9/1/09
Description Triple-digit temperatures, extremely low relative humidities, dense vegetation that has not burned in decades, and years of extended drought are all contributing to the explosive growth of wildfires throughout Southern California. The Station fire, which began Aug. 26, 2009, in La Canada/Flintridge, not far from NASA's Jet Propulsion Laboratory, had reportedly burned 105,000 acres (164 square miles) of the Angeles National Forest by mid-day Aug. 31, destroying at least 21 homes and threatening more than 12,000 others. It is one of four major fires burning in Southern California at the present time. This image was acquired mid-morning on Aug. 30 by the backward (northward)-viewing camera of the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite. The image is shown in an approximate perspective view at an angle of 46 degrees off of vertical. The area covered by the image is 245 kilometers (152 miles) wide. Several pyrocumulus clouds, created by the Station Fire, are visible above the smoke plumes rising from the San Gabriel Mountains north of Los Angeles in the left-center of the image. Smoke from the Station fire is seen covering the interior valleys along the south side of the San Gabriel Mountains, along with parts of the City of Los Angeles and Orange County, and can be seen drifting for hundreds of kilometers to the east over the Mojave Desert. The accompanying plots are histograms that display the heights of the smoke plumes and wind speeds. In this data set, the plume is injecting smoke more than 7 kilometers (4.3 miles) above sea level. MISR observes the daylit Earth continuously and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. This image was generated from a portion of the imagery acquired during Terra orbit 51601. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Science Mission Directorate, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, Md. The MISR data were obtained from the NASA Langley Research Center Atmospheric Science Data Center.

Date 5/19/00
Description The fire that has raged out of control this month near Los Alamos, New Mexico, was captured in a series of images by the Multi-angle Imaging Spectro-Radiometer (MISR) on NASA's Terra satellite. The picture is available at http://www.jpl.nasa.gov/pictures/misr These true-color images covering north-central New Mexico capture the bluish-white smoke plume of the Los Alamos fire, just west of the Rio Grande river. The middle image is a downward-looking or "nadir" view taken by MISR. As the satellite flew from north to south, the instrument viewed the scene from nine different angles. The top image was taken by the MISR camera looking 60 degrees forward along its orbit, whereas the bottom image looks 60 degrees aft. The fire plume stands out more dramatically in the steep-angle views. Its color and brightness also change with angle. By comparison, a thin, white water cloud appears in the upper right portion of the scene, and is most easily detected in the top image. MISR scientists use these angle-to-angle differences to monitor particulate pollution and to identify different types of haze. Such observations allow scientists to study how airborne particles interact with sunlight, a measure of their impact on Earth's climate system. The images are about 400 km (250 miles) wide. The spatial resolution of the nadir image is 275 meters (300 yards), resolution is 1.1 kilometers (1,200 yards) for the off-nadir images. North is toward the top. MISR is managed by the Jet Propulsion Laboratory, a division of the California Institute of Technology, for NASA' s Office of Earth Science, Washington, D.C.

Date 8/18/00
Description These images show forest fires raging in Montana and Hurricane Hector swirling in the Pacific. These two unrelated, large-scale examples of nature's fury were captured by the Multi-angle Imaging SpectroRadiometer (MISR) during a single orbit of NASA's Terra satellite on August 14, 2000. In the left image, huge smoke plumes rise from devastating wildfires in the Bitterroot Mountain Range near the Montana-Idaho border. Flathead Lake is near the upper left, and the Great Salt Lake is at the bottom right. Smoke accumulating in the canyons and plains is also visible. This image was generated from the MISR camera that looks forward at a steep angle (60 degrees), the instrument has nine different cameras viewing Earth at different angles. The smoke is far more visible when seen at this highly oblique angle than it would be in a conventional, straight- downward (nadir) view. The wide extent of the smoke is evident from comparison with the image on the right, a view of Hurricane Hector acquired from MISR's nadir-viewing camera. Both images show an area of approximately 400 kilometers (250 miles) in width and about 850 kilometers (530 miles) in length. When this image of Hector was taken, the eastern Pacific tropical cyclone was located approximately 1,100 kilometers (680 miles) west of the southern tip of Baja California, Mexico. The eye is faintly visible and measures 25 kilometers (16 miles) in diameter. The storm was beginning to weaken, and 24 hours later the National Weather Service downgraded Hector from a hurricane to a tropical storm. MISR, built and managed by the Jet Propulsion Laboratory, is one of several Earth-observing instruments aboard Terra, which was launched in December 1999.

Description The desert takes to the skies in these images of eastern China from NASA's Multi-angle Imaging SpectroRadiometer (MISR). A hazy summer view from July 9, 2000, (left) compares with a spectacularly dusty spring view from April 7, 2001, (middle). The two images cover an area from central Manchuria near the top to portions of North and South Korea at the bottom. The image on the right is a higher resolution MISR nadir- camera view of a portion of the April 7, 2001, dust cloud. When viewed at full magnification, a number of atmospheric wave features, like the ridges and valleys of a fingerprint, are apparent. These are probably induced by surface topography, which can disturb the wind flow. A few small cumulus clouds are also visible and are casting shadows on the thick lower dust layer. According to the Xinhua News Agency in China, nearly one million tons of Gobi Desert dust blow into Beijing each year. During a similar dust outbreak last year, the Associated Press reported that the visibility in Beijing had been reduced to the point where buildings were barely visible across city streets and airline schedules were significantly disrupted. The dust has also been implicated in adverse health effects such as respiratory discomfort and eye irritation. Asia's desert areas are prone to soil erosion, as underground water tables are lowered by prolonged drought and by industrial and agricultural water use. Heavy winds blowing eastward across the arid and sparsely vegetated surfaces of Mongolia and western China pick up large quantities of yellow dust. Airborne dust clouds from the April 2001 storm blew across the Pacific Ocean and were carried as far as North America. The minerals transported in this manner are believed to provide nutrients for both oceanic and land ecosystems. The left-hand and middle images are from Terra orbits 2,967 and 6,928 respectively. They are approximately 380 kilometers (236 miles) in width. The right-hand image covers an area roughly 250 kilometers (155 miles) wide by 470 kilometers (292 miles) high. Analyses of images such as these constitute one phase of MISR's participation in the Asian-Pacific Regional Aerosol Characterization Experiment, an international campaign aimed at studying the offshore transport of airborne particles from the Asian continent. More information about this international endeavor is available online at http://saga.pmel.noaa.gov/aceasia/ . MISR, built and managed by NASA's Jet Propulsion Laboratory, is one of several Earth-observing experiments aboard Terra, launched in December 1999. MISR acquires images of the Earth at nine angles simultaneously, using nine separate cameras pointed forward, downward, and backward along its flight path.

Description Nicaraguan Volcanoes The true-color image at left is a downward-looking (nadir) view of the area around the San Cristobal volcano, which erupted the previous day. This image is oriented with east at the top and north at the left. The right image is a stereo anaglyph of the same area, created from red band multi-angle data taken by the 45.6-degree aftward and 70.5-degree aftward cameras on the Multi- angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite. View this image through red/blue 3D glasses, with the red filter over the left eye. A plume from San Cristobal (approximately at image center) is much easier to see in the anaglyph, due to 3 effects: the long viewing path through the atmosphere at the oblique angles, the reduced reflection from the underlying water, and the 3D stereoscopic height separation. In this image, the plume floats between the surface and the overlying cumulus clouds. A second plume is also visible in the upper right (southeast of San Cristobal). This very thin plume may originate from the Masaya volcano, which is continually degassing at a slow rate. The spatial resolution is 275 meters (300 yards). MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

Description Multi-Angle Views of the Appalachian Mountains The true-color image at left is a downward-looking (nadir) view of the eastern United States, stretching from Lake Ontario to northern Georgia, and spanning the Appalachian Mountains. The three images to the right are also in true-color, taken by the forward 45.6-degree, 60.0-degree, and 70.5-degree cameras, respectively, of the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite. As the slant angle increases, the line- of-sight through the atmosphere grows longer, and a pall of haze over the Appalachians becomes progressively more apparent. You can see a similar effect by scanning from near-nadir to the horizon when standing on a mountain top or looking out an airplane window. MISR uses this multi-angle technique to monitor particulate pollution and to distinguish different types of haze. These observations reveal how airborne particles are interacting with sunlight, a measure of their impact on Earth's climate system. The images are about 400 km (250 miles) wide, and the spatial resolution is 1.1 kilometers (1,200 yards). North is toward the top. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

Description A multi-angle view of the Canary Islands in a dust storm, 29 February 2000. At left is a true-color image taken by the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite. This image was captured by the MISR camera looking at a 70.5-degree angle to the surface, ahead of the spacecraft. The middle image was taken by the MISR downward- looking (nadir) camera, and the right image is from the aftward 70.5-degree camera. The images are reproduced using the same radiometric scale, so variations in brightness, color, and contrast represent true variations in surface and atmospheric reflectance with angle. Windblown dust from the Sahara Desert is apparent in all three images, and is much brighter in the oblique views. This illustrates how MISR's oblique imaging capability makes the instrument a sensitive detector of dust and other particles in the atmosphere. Data for all channels are presented in a Space Oblique Mercator map projection to facilitate their co-registration. The images are about 400 km (250 miles) wide, with a spatial resolution of about 1.1 kilometers (1,200 yards). North is toward the top. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

Description At left is a true-color image from the downward-looking (nadir) camera on the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite. The false-color image at right is a composite of red band data taken by the MISR forward 45.6-degree, nadir, and aftward 45.6-degree cameras, displayed in blue, green, and red colors, respectively. Color variations in the left image highlight spectral (true-color) differences, whereas those in the right image highlight differences in angular reflectance properties. The purple areas in the right image are low cloud, and light blue at the edge of the bay is due to increased forward scattering by the fast (smooth) ice. The orange areas are rougher ice, which scatters more light in the backward direction. This example illustrates how multi-angle viewing can distinguish physical structures and textures. Data for all channels are presented in a Space Oblique Mercator map projection to facilitate their co- registration. The images are about 400 km (250 miles) wide with a spatial resolution of about 275 meters (300 yards). North is toward the top.

Date 4/3/01
Description These two images of Pine Island Glacier in Antarctica show the recently discovered 25-kilometer (15-mile) long crack that scientists expect will turn into a large iceberg within the next 18 months. The views from NASA's Multi-angle Imaging SpectroRadiometer (MISR) on the Terra satellite also reveal differences in the ice sheet's surface texture, highlighting surface fractures and enabling distinction of rough crevasses from smooth blue ice. The image data shown was acquired on December 12, 2000, during Terra orbit 5246. At left is a conventional, true-color image from the downward-looking (nadir) camera. The false-color image at right is a composite of red-band data taken by the MISR forward 60-degree, nadir, and aftward 60-degree cameras, displayed in red, green and blue, respectively. Color variations in the true-color image at left highlight spectral differences. In the multi-angle composite, on the other hand, color variations act as a proxy for differences in the angular reflectance properties of the scene. In this representation, clouds show up as light purple. Blue to orange gradations on the surface indicate a transition in ice texture from smooth to rough. For example, the bright orange carrot-like features are rough crevasses on the glacier's tongue. In the conventional nadir view, the blue ice labeled "rough crevasses"' and "smooth blue ice" are similarly colored, but the multi-angle composite reveals their different textures, with the smoother ice appearing dark purple instead of orange. This could be an indicator of different mechanisms by which this ice is exposed. The multi-angle view also reveals subtle roughness variations on the frozen sea ice between the glacier and the open water in Pine Island Bay. To the left of the 'icebergs' label are chunks of floating ice. Smaller icebergs embedded in the frozen sea ice are visible below and to the right of the label. These small icebergs are associated with dark streaks. Analysis of the illumination geometry suggests that these streaks are surface features, not shadows. Wind-driven motion and thinning of the sea ice in the vicinity of the icebergs are a possible explanation. Recently, Robert Bindschadler, a glaciologist at the NASA Goddard Space Flight Center discovered in Landsat 7 imagery a newly-formed crack traversing the Pine Island Glacier. This crack is visible as an off-vertical dark line in the MISR nadir view. In the multi-angle composite, the crack and other stress fractures show up very clearly in bright orange. Radar observations of Pine Island Glacier in the 1990's showed the glacier to be shrinking, and the newly discovered crack is expected to eventually lead to the calving of a major iceberg.

Title Hubble's Sharpest View of Mars
General Information What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. The recently refurbished Hubble telescope obtained the sharpest view of Mars ever taken from Earth. This stunning portrait was taken with March 10, 1997, just before the Red Planet made one of its closest passes to Earth (about 60 million miles or 100 million kilometers). The Martian North Pole is at the top [near the center of the bright polar cap] and east is to the right. This view of Mars was taken on the last day of Martian spring in the Northern Hemisphere.
A Summer View of Russia's Le …
Title A Summer View of Russia's Lena Delta and Olenek River
Description These views of the Russian Arctic were acquired by NASA's Multi-angle Imaging SpectroRadiometer (MISR) instrument on July 11, 2004. The brief arctic summer had transformed the frozen tundra and the thousands of lakes, channels, and rivers of the Lena Delta into a fertile wetland, and the usual blanket of thick snow had melted from the vast plains and taiga forests. The images show an area in the northern part of the Sakha Republic in eastern Siberia. The Olenek River wends northeast from the bottom of the images to the upper left, and the delta through which the mighty Lena River empties into the Laptev Sea dominate the top portions of the images. Creating accurate maps of vegetation structure is essential for understanding the seasonal exchanges of energy and water at the Earth's surface and for preserving biodiversity. The left-hand image is a natural-color image from MISR's nadir (vertical-viewing) camera, in which the rivers appear murky due to sediment, and photosynthetically active vegetation appears green. The center image is also from MISR's nadir camera, but is a false-color view in which the predominant red color is due to the brightness of vegetation at near-infrared wavelengths. Apart from the Lena Delta, the most photosynthetically active regions are within the lower half of the image and throughout the great stretch of land that curves across the Olenek River.  The relatively barren ranges of the Volyoi Mountains appear as the pale tan-colored area to the right of image center. The right-hand image is a multiangle, false-color view made from the red band data of the 60-degree-backward, nadir, and 60-degree-forward cameras, displayed as red, green and blue, respectively. Water appears blue in this image because sun glint makes smooth, wet surfaces look brighter at the forward camera's view angle. Much of the landscape and many low clouds appear purple because these surfaces are both forward and backward scattering, and clouds that are further from the surface appear in a different spot for each view angle, creating a rainbow-like appearance. The highly vegetated region in the natural-color nadir image exhibits a faint greenish hue in the multi-angle composite. This subtle effect suggests that the nadir camera is observing more of the brighter, underlying surface than the oblique cameras, providing information about the distribution and density of trees and shrubs in this area. The Multiangle Imaging SpectroRadiometer observes the daylit Earth continuously, and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. The MISR Browse Image Viewer [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://eosweb.larc.nasa.gov/MISRBR/ ], provides access to low-resolution true-color versions of these images. These data products were generated from a portion of the imagery acquired during Terra orbit 24273. The panels cover an area of about 230 kilometers x 420 kilometers, and utilize data from blocks 30 to 34 within World Reference System-2 path 134.

Angora Fire
Title Angora Fire
Description On the weekend of June 23, 2007, a wildfire broke out south of Lake Tahoe, which stretches across the California-Nevada border. By June 28, the Angora Fire [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14323 ] had burned more than 200 homes and forced some 2,000 residents to evacuate, according to The Seattle Times and the Central Valley Business Times. On June 27, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite captured this image of the burn scar left by the Angora fire. The burn scar is dark gray, or charcoal. Water bodies, including the southern tip of Lake Tahoe and Fallen Leaf Lake, are pale silvery blue, the silver color a result of sunlight reflecting off the surface of the water. Vegetation ranges in color from dark to bright green. Streets are light gray, and the customary pattern of meandering residential streets and cul-de-sacs appears throughout the image, including the area that burned. The burn scar shows where the fire obliterated some of the residential areas just east of Fallen Leaf Lake. According to news reports, the U.S. Forest Service had expressed optimism about containing the fire within a week of the outbreak, but a few days after the fire started, it jumped a defense, forcing the evacuation of hundreds more residents. Strong winds that had been forecast for June 27, however, did not materialize, allowing firefighters to regain ground in controlling the blaze. On June 27, authorities hoped that the fire would be completely contained by July 3. According to estimates provided in the daily report from the National Interagency Fire Center, [ http://www.nifc.gov/information.html ] the fire had burned 3,100 acres (about 12.5 square kilometers) and was about 55 percent contained as of June 28. Some mandatory evacuations remained in effect. You can download a 15-meter-resolution KMZ file of the Angora fire [ http://earthobservatory.nasa.gov/Newsroom/NewImages/Images/tahoe_ast_2007178.kmz ] suitable for use with Google Earth.

Cloud Heights of Frances and …
Title Cloud Heights of Frances and Ivan
Description NASA's Multi-angle Imaging SpectroRadiometer [ http://www-misr.jpl.nasa.gov ] (MISR) captured these images and cloud-top height retrievals of Hurricane Frances on September 4, 2004, when the eye sat just off the coast of eastern Florida, and Hurricane Ivan on September 5, after the storm had devastated Grenada and was heading toward the central and western Caribbean. Hurricane Frances made landfall in the early hours of September 5, and was downgraded to Tropical Storm status as it swept inland through the Florida panhandle and continued northward. Following on the heels of Frances is Hurricane Ivan, which is on record as the strongest tropical hurricane to form at such a low latitude in the Atlantic, and was the most powerful storm to have hit the Caribbean in nearly a decade. The ability of forecasters to predict the intensity and amount of rainfall associated with hurricanes still requires improvement, especially on the 24- to 48-hour timescale vital for disaster planning. To improve the operational models used to make hurricane forecasts, scientists need to better understand the multi-scale interactions at the cloud, mesoscale and synoptic scales that lead to hurricane intensification and dissipation, as well as the various physical processes that determine hurricane intensity and rainfall distributions. Because these uncertainties with regard to how to represent cloud processes still exist, it is vital that the model findings be evaluated against hurricane observations whenever possible. Two-dimensional maps of cloud height such as those shown here offer an unprecedented opportunity for comparing simulated cloud fields against actual hurricane observations. The lefthand panel in each image pair is a natural-color view from MISR's nadir camera. The righthand panels are cloud-top height retrievals produced by automated computer recognition of the distinctive spatial features between images acquired at different view angles. These results indicate that at the time that these images were acquired, clouds within Frances and Ivan had attained altitudes of 15-16 kilometers (9-10 miles) above sea level, respectively. The height fields pictured here are uncorrected for the effects of cloud motion. Wind-corrected heights (which have higher accuracy but coarser spatial coverage) are within about 1 kilometer of the heights shown here. (Visit the Earth Observatory's Natural Hazards Severe Storms [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?topic=storm ] section to view more recent images of Hurricanes Ivan and Frances.)

Day Fire in Southern Califor …
Title Day Fire in Southern California
Description While the outline of a fire may be hidden by thick smoke in a photo-like, "natural-color" image, "false-color" images that use visible as well as short-wave or near-infrared light observed by remote-sensing instruments can reveal details on the ground. This pair of images shows the Day Fire in southern California northwest of Los Angeles on September 19, 2006. The images are based on data collected by an aircraft-based sensor called MASTER, [ http://masterweb.jpl.nasa.gov/ ] a simulator for two sensors on NASA's Terra [ http://terra.nasa.gov ] satellite. (NASA uses airborne simulators to cross-check the accuracy of satellite data.) In the natural-color version (bottom), dingy white smoke hangs over most of the scene, hiding the outline of the fire. But in the infrared-enhanced version (top), the actively burning areas around the perimeter of the blaze are obvious as glowing pink and yellow spots, while the smoke fades into a transparent blue. Unburned vegetation appears green, while the burned area appears in shades of brown and gold. The MASTER instrument simulates the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensors on Terra. The instrument can be mounted on several different aircraft, including NASA's ER-2 [ http://www.nasa.gov/centers/dryden/news/FactSheets/FS-046-DFRC.html ] and WB-57 [ http://jsc-aircraft-ops.jsc.nasa.gov/wb57/index.html ] airplanes.

Hurricane Ivan
Title Hurricane Ivan
Description Interstate 10 is a heavily traveled roadway connecting Florida?s panhandle to the west. The road stretches from the eastern shore of northern Florida to Los Angeles, California, skirting the Gulf shore to Houston, then following the Mexican border to California. Just before leaving Florida, a traveler on I-10 would cross Escambia Bay near Pensacola. That was before Hurricane Ivan blasted through the Florida panhandle. The storm?s fierce 130-mile-per-hour winds and possibly its storm surge cut through the bridge, leaving a wide gap in Interstate 10. The gap is visible in this image, acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER [ http://asterweb.jpl.nasa.gov/ ]) aboard NASA?s Terra [ http://terra.nasa.gov/ ] satellite on September 21, 2004, five days after Ivan made landfall. The road forms a thin white line across the dark waters of Escambia Bay in a comparison image, taken on September 28, 2003. In the 2004 image, the line is broken. Further evidence of Ivan's fury is visible in the top image. Large tracts of darker red regions along the Escambia River, left, and the Yellow River, right, are probably flooded. This pair of false-color composite images was made by combining the near infrared, red, and green wavelengths (ASTER bands 3, 2, & 1), making vegetation appear red and water look black.

Just before leaving Florida, a traveler on I-10 would cross Escambia Bay near Pensacola. That was before Hurricane Ivan blasted through the Florida panhandle. The storm?s fierce 130-mile-per-hour winds and possibly its storm surge cut through the bridge, leaving a wide gap in Interstate 10. The gap is visible in this image, acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER [ http://asterweb.jpl.nasa.gov/ ]) aboard NASA?s Terra [ http://terra.nasa.gov/ ] satellite on September 21, 2004, five days after Ivan made landfall. The road forms a thin white line across the dark waters of Escambia Bay in a comparison image, taken on September 28, 2003. In the 2004 image, the line is broken. Further evidence of Ivan's fury is visible in the top image. Large tracts of darker red regions along the Escambia River, left, and the Yellow River, right, are probably flooded. This pair of false-color composite images was made by combining the near infrared, red, and green wavelengths (ASTER bands 3, 2, & 1), making vegetation appear red and water look black.

Caption details provided by Clare Averill (Raytheon ITSS/Jet Propulsion Laboratory), David J. Diner, Mike Garay and Ralph Kahn (Jet Propulsion Laboratory) and Greg McFarquhar (University of Illinois at Urbana-Champaign)., MISR stereo-height estimates (not shown here) indicate that the highest clouds reach 18-19 kilometers above the surface of the Earth. The stereo anaglyph shows relative height variations and enhances the appearance of thin clouds, such as those that mark the series of gravity waves north-east of the eyewall. Atmospheric gravity waves are caused by air displacements in an otherwise stable air layer. In this case, the gravity waves are above the hurricane arms in the upper troposphere, and were probably generated as the towering storm updraft tried to push into the stable air between the troposphere and the stratosphere (known as the tropopause). Some of Katrina's cloud tops were about 2 kilometers above the tropopause. Such high "overshooting tops" are also characteristic of strong and rapidly growing storms. The animation progresses from MISR's most forward-pointing camera, which views the scene first, to the most backward-pointing camera, which views the scene last. It was created by aligning the views from all 9 cameras using the high clouds within the eyewall as a reference point. North is at the top. The convective cloud towers, especially those along the eastern sides of the inner and outer eyewalls, attain the highest altitudes and indicate that the storm is strengthening. Those areas that do not exhibit cloud-top convection are clouds experiencing vertical wind shear, and tend to be lower than the towering cloud structures. The vertical and horizontal development of the convective clouds and the formation of an outer ring of growing clouds (referred to as an "eyewall replacement cycle") also indicate rapid strengthening. During this stage of hurricane development, an outer band of clouds may gradually move inward to replace the existing hurricane eyewall, causing the central pressure to increase and weaken the storm in the short term. However, eyewall replacement may sometimes be a forerunner for rapid strengthening in the longer term. This was the case with Hurricane Katrina, whose central pressure increased slightly on Saturday, but then dropped again significantly on Sunday when Katrina became a Category 5 storm. Observing the development of a concentric eyewall at this spatial and temporal resolution is a unique feature of these MISR observations. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously, viewing the entire globe between 82 degrees North and 82 degrees South latitude every nine days.

Title Earthquake Raises Reefs in the Solomon Islands
Description When people talk about change happening on a geologic time scale, most of the time, they mean that the change happens over the course of millions of years: the Colorado River gradually cuts through the soft rock of the Colorado Plateau until it has made a 4,000-foot-deep chasm, the Grand Canyon, continents drift centimeters at a time, slowly changing the shape and position of landmasses on the Earth. Most of the time, change is slow, but sometimes, geologic change happens all at once. This was the case on Ranongga Island in the Solomon Islands. In the early morning hours of April 2, 2007, a magnitude 8.1 earthquake shook the Solomon Islands, its epicenter southwest of Ranongga Island. The huge quake pushed much of the island up, raising the coral reefs that ringed the island above the water. In the course of a few minutes, Ranongga Island acquired several meters of new beach. The newly exposed reef forms a gray rim along the eastern shore of the island in the left image, acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on April 12, 2007. In the right image, taken on March 31, 2006, the shallowly submerged reefs color the water a lighter shade of blue. The uplift may be more dramatic than the images show. When ASTER took the 2007 image, the tide was 29.4 centimeters higher than it was when the 2006 image was taken, and yet the uplift is still visible. The lush vegetation that covers the tropical island is bright red in this image, which is made from both visible and infrared light. Out of its aquatic environment, the reef died, becoming the foundation of new land. Such evolution is common in earthquake zones in the Pacific and Indian Oceans. During the December 26, 2004, earthquake that generated the massive Indian Ocean tsunami, Simeulue Island was lifted as much as 150 centimeters (4.9 feet), exposing the reef that surrounded it. A similar set of exposed fossilized reefs on the shores of Papua New Guinea, near the Solomon Islands, provided proof that wobbles in the Earth's orbit trigger ice ages.

Rice Cultivation in Northwes …
Title Rice Cultivation in Northwest Italy
Description The lowlands of Lombardy and Piedmont in northwest Italy are some of the most highly developed irrigation areas in the world. Irrigated lands cover at least 160,000 acres in this part of Italy, where rice is the most important crop. These views of the region were acquired on May 8, 2005, by NASA's Multi-angle Imaging SpectroRadiometer (MISR). The multiple viewing angles provided by MISR's nine cameras make it possible to tell wet surfaces, including flooded lands, from other surfaces, and they also make cities easy to locate. The left-hand image is a natural-color view acquired by MISR's downward-looking (nadir) camera, and the right-hand image is a combination of red band data from MISR's 60-degree-backward-, nadir, and 60-degree-forward-viewing cameras. (Red band is what scientists call the "channel" on the sensor that detects red light.) Color changes indicate surface texture, which is influenced by terrain, vegetation structure, soil type, and surface wetness. Wet surfaces or areas with standing water appear in blue or purple-blue hues. The purple-blue areas that dominate the center-left part of the image are part of the extensive irrigation network that exists throughout the plains and meadows of the region. Cities with tall buildings appear in red-orange hues. In this type of image, the city of Milan is the most obvious. The small orange area in the center of the purple inundated area indicates the location of Vercelli, and the larger city of Milan is the orange area to the northeast, on the other side of the Ticino River. To a lesser extent, the cities of Novara, Pavia, Galliate, Mortara, and Vigevano are also identifiable by their orange hues. MISR can tell various surface features like cities or irrigated areas apart because of the way surfaces reflect light. A smooth water surface tends to reflect sunlight away from the Sun. This effect is most apparent when a satellite views the surface with the Sun in front of the camera. Similarly, rough surfaces tend to reflect light back towards the Sun, and this "backward scattering" is most obvious when a satellites views a surface with the Sun behind the camera. Clouds present over the high country to the west of the Lago Maggiore (upper left corner) and along the coast of the Golfo di Genova (bottom) appear in a different spot for each view angle, creating a rainbow-like appearance. Mountains also have a "wavy" look in the multi-angle combination because, like clouds, their height above the surface makes them appear in a different spot in each camera's view angle. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously, viewing the entire globe between 82 degrees North and 82 degrees South latitude every nine days. This image covers an area of about 131 kilometers by 191 kilometers. These data products were generated from a portion of the imagery acquired during Terra orbit 28660 and utilize data from block 54 within World Reference System-2 path 193.

Title San Miguel and Santa Rosa Islands
Description Off the California coast lies a series of small islands, all part of the Channel Islands National Park. [ http://www.nps.gov/chis ] On May 29, 2005, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite captured this image of two of those islands: San Miguel and Santa Rosa. The westernmost island, San Miguel, is primarily a plateau, most of it with an elevation of approximately 150 meters (500 feet), although some hills on the island reach roughly 250 meters (800 feet). At just 9,500 acres (38 square kilometers), San Miguel faces a constant barrage of North Pacific winds. Strong stripes, resulting from linear sand dunes, cross this island from its northwestern beaches toward the southeast. In between the dunes, however, vegetation appears lush. According to the National Park Service, the island had been characterized as a "barren lump of sand" in the late nineteenth century, thanks to a century of overgrazing. Removal of the grazing animals eventually restored the island's flora. San Miguel's neighbor, Santa Rosa, sports no stripes, and seems slightly less lush. Santa Rosa is the second-largest island off the California coast, at 53,000 acres (214 square kilometers). Only its eastern neighbor, Santa Cruz, is larger. Santa Rosa has generally low elevation except for its central mountain range that reaches up to roughly 484 meters (1,589 feet). Like its elevation, Santa Rosa's coastline also varies, from wide sandy beaches to steep cliffs. In the water around the islands, kelp forests rise up from the ocean floor.

Title Sierra Nevada Range, Mokelumne Wilderness
Description South of Lake Tahoe, in the Sierra Nevada mountain range in California, the boundaries of three national forests—Stanislaus, El Dorado, and Humboldt-Toiyabe—meet. At the intersection of these boundaries sits the Mokelumne Wilderness Area, [ http://www.fs.fed.us/r5/stanislaus/visitor/mokelumne.shtml ] which straddles the crest of the Sierra Nevada. On June 29, 2007, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image of the Mokelumne and surrounding forests. In this simulated true-color image, dark green indicates thick vegetation, pale green indicates sparse vegetation, dark blue indicates water, and beige and gray indicate bare ground. National Park boundaries appear in white. The terrain in the area is rugged, with steep mountain crags interspersed with occasional lakes with jagged contours. At high elevations, forests give way to alpine plants, and finally, to bare rock. A pale shoreline outlines Spicer Reservoir, near the bottom of the image, suggesting a dip in the lake's water level, consistent with warm, dry [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14393 ] conditions that predominated in the American West in the early summer of 2007. Not all national forests are wilderness area, many forests offer timber concessions. In Stanislaus National Forest, in the lower left corner of this image, tiny pale patches break the forest cover. In the high-resolution imagery, the precise geometric outlines of these patches are more obvious, such patterns are consistent with clear-cut logging.

Fires in Southern California
Title Fires in Southern California
Description *High-resolution Images:* November 2, 2003(3.9 Mb JPEG) September 22, 2003 (3.2 Mb JPEG) The image above (top) shows burn scars around Lake Piru in the Santa Susana Mountains near Santa Clara, California, northwest of Los Angeles. The earlier image shows the same area on September 22, 2003, prior to when the fires swept through. In the earlier image, healthy vegetation appears green, and naturally bare ground (or ground with sparse vegetation) appears pink. A few weeks later, fire has transformed the scene. The areas to the east and northeast of the lake appear unchanged, while the entire left and lower right portions of the scene exhibit the deep red color that burned areas take on in false-color images made from satellite observations of the near and shortwave infrared part of the electromagentic spectrum. In the November 2, 2003, image, the nothern end of the lake is quite turbid, which could have been caused by ash and fire debris. This pair of false-color ASTER image composites was created using shortwave infrared, near infrared, and green wavelengths (ASTER bands 5, 3, and 1). Please also see a high-resolution view of the Santa Monica hills using a different set of ASTER bands to emphasis different details, as well as a MODIS false-color image showing a wider area.

Fires in Southern California
Title Fires in Southern California
Description Part of the firestorm that swept through Southern California in late October 2007, the Poomacha Fire east of Pauma Valley was still smoldering in a few interior locations as of November 8, according to the National Interagency Fire Center. This image from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite on November 6 shows the burned landscape of the Poomacha Fire using a combination of visible and infrared light. The burned area in the center of the image is bright pink. Naturally bare (or thinly vegetated) land surfaces are lighter pink. Vegetation is bright green. The fire took its name from a street in a community on the reservation, La Jolla Amago, where at least 8 homes were destroyed. You can download a 15-meter-resolution KMZ file of the Poomacha fire scar [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Nov2007/scal_ast_2007310.kmz ] suitable for use with Google Earth.

Tropical Cyclone Monty
Title Tropical Cyclone Monty
Description The Multi-angle Imaging SpectroRadiometer (MISR) acquired these natural color images and cloud top height measurements for Monty before and after the storm made landfall over the remote Pilbara region of Western Australia, on February 29 and March 2, 2004 (shown as the left and right-hand image sets, respectively). On February 29, Monty was upgraded to category 4 cyclone status. After traveling inland about 300 kilometers to the south, the cyclonic circulation had decayed considerably, although category 3 force winds were reported on the ground. Some parts of the drought-affected Pilbara region received more than 300 millimeters of rainfall, and serious and extensive flooding has occurred. The natural color images cover much of the same area, although the right-hand panels are offset slightly to the east. Automated stereoscopic processing of data from multiple MISR cameras was utilized to produce the cloud-top height fields. The distinctive spatial patterns of the clouds provide the necessary contrast to enable automated feature matching between images acquired at different view angles. The height retrievals are at this stage uncorrected for the effects of the high winds associated with cyclone rotation. Areas where heights could not be retrieved are shown in dark gray. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. These data products were generated from a portion of the imagery acquired during Terra orbits 22335 and 22364. The panels cover an area of about 380 kilometers x 985 kilometers, and utilize data from blocks 105 to 111 within World Reference System-2 paths 115 and 113. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

Title Zaca Wildfire, Southern California
Description In early August 2007, the month-old Zaca Fire in Southern California was racing over the hilly terrain along the southwest margin of the Los Padres National Forest. Started accidentally on private ranch land near the forest in early July, the fire quickly got out of control in the hot, dry, windy conditions the area was experiencing in summer 2007. As of August 8, the fire had burned an estimated 72,050 acres and was about 68 percent contained. This image of the fire was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA'Terra [ http://terra.nasa.gov ] satellite on August 7. Unburned vegetation appears green, while the burned area appears charcoal-colored. Smoke hangs over the area. You can download a 15-meter-resolution KMZ file of the Zaca fire [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Aug2007/zaca_ast_2007218.kmz ] suitable for use with Google Earth.

Spring Flooding on the Missi …
Title Spring Flooding on the Mississippi
Description The mighty Mississippi River, from its source at Lake Itasca, Minnesota to the Gulf of Mexico, is approximately 3780 kilometers long and has flooded many times during its history. In April 2001, residents of Minnesota, Wisconsin, Iowa, and Illinois once again battled near-record water levels. These Multi-angle Imaging SpectroRadiometer (MISR) images, acquired one month apart, illustrate the effects of snowmelt and heavy rainfall on areas traversed by the upper Mississippi River. Each image in this pair covers an identical 195-kilometer x 339-kilometer area. The one on the left was acquired March 26, 2001 (Terra orbit 6762), and the one on the right is from April 27 (Terra orbit 7228). Both are false-color composites, displaying data from the near-infrared band of the instrument's nadir (vertical-viewing) camera as red, the green band of the nadir camera as green, and the red band of the 26-degree forward camera as blue. Data from the forward-viewing camera is included to enhance the reflectivity of water. The near-infrared data provide a good indicator of the abundance of vegetation since plants are highly reflective in this spectral region. The redder color of the right-hand image is due to increased vegetation cover brought about by wet conditions and the onset of spring. Locations of major cities are marked on the left-hand image, major rivers are marked on the right. The portion of the Mississippi River captured in these views extends from just north of La Crosse, Wisconsin to south of Davenport, Iowa. The Wisconsin River joins the Mississippi just below Prairie du Chien. On March 26, snow can clearly be seen over much of the northern portions of the left-hand image. At this point in time, the snow had already begun to melt and the Wapsipinicon River was 52 centimeters above flood stage at De Witt, Iowa (between Clinton and Davenport). By mid-April heavy rainfall swelled the Mississippi and Wisconsin rivers. In the early morning of April 25, two days before the right-hand image was acquired, the Mississippi River crested in Davenport, Iowa at 680 centimeters, slightly below the level reached in the record-setting flood of 1993. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.
