Title Great Zoom into Chicago, IL: The Sears Tower
Abstract Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves floating in virtual space just above the ground.

At 1:00 p.m., National Weather Service gauges [ http://newweb.erh.noaa.gov/ahps2/hydrograph.php?wfo=cle&gage=fdyo1&view=1,1,1,1,1,1,1,1&toggles=10,7,8,2,9,15,6 ] in Findlay, Ohio, recorded water levels of 18.46 feet, just under six and a half inches short of the record crest of 18.5 feet set on March 13, 1913. In both cases, the river rose more than seven feet above its flood stage of 11 feet. The August 22 flood swamped the city of Findlay, forcing hundreds from their homes and putting the city in a state of emergency, reported the Associated Press on August 23. The disastrous floods along the Blanchard River can be seen in the top image. The image was made with a combination of visible and infrared light to increase the contrast between water and land. Water is dark blue or black, while plant-covered land is bright green. Tiny squares of plant-free land, most like fallow fields in this case, are tan. Cities are gray, looking like a dark smudge against the bright green landscape. Lingering clouds are light blue and white. The severity of the flood can be gauged by comparing the top image with the lower image, which was taken on August 13, 2007. In the lower image, the Blanchard River is too small to be visible. By August 22, the river and many of its tributaries are clearly visible. The river expands over Findlay, and then bends south. Ohio was not the only state that experienced floods in mid-August. A string of severe thunderstorms [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14462 ] dumped heavy rain on several Midwest states, including Minnesota, Wisconsin, Iowa, Illinois, Indiana, and Ohio. At the same time, the remnants of Tropical Storm Erin [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14454 ] triggered deadly flooding in Oklahoma and Texas.

Illinois, Indiana, and Kentucky are shown in these false-color Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) images where water is black, vegetation is green, and clouds are white and peach. In the top image, taken on January 7, 2004, by the Terra [ http://terra.nasa.gov/ ] satellite, the Ohio, Wabash, and White Rivers are noticeably wider compared to an image acquired just one week earlier. The Ohio and the Wabash Rivers form a ?v? in the center of the image, with the Ohio River on the south. Near the top of the image, the White River branches off of the Wabash River. Other area rivers also appear to be fuller. The states affected by the floods include Illinois, Indiana, Ohio, Kentucky, and West Virginia. According to news reports, the flood waters are covering mostly farmland, though houses and roads were also flooded. Cold temperatures followed the storm, making clean-up difficult. The high-resolution images provided above have a resolution of 500 meters per pixel.

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.) The MISR observes the daylit Earth continuously and every 9 days views the entire globe between 82° north and 82° south latitude. These data products were generated from a portion of the imagery acquired during Terra [ http://terra.nasa.gov ], orbits 25081 and 25094. The panels cover an area of 380 kilometers x 924 kilometers, and utilize data from within blocks 65 to 87 within World Reference System-2 paths 14 and 222, respectively. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

Haze Over the Midwestern Uni …
Title Haze Over the Midwestern United States
Description High pressure over the central United States led to hot temperatures and an accumulation of pollutants on August 8, 2005. The Environmental Protection Agency warned that air quality index levels could be unhealthy for the Midwest, and western and southern Great Lakes areas. The EPA advised individuals with respiratory sensitivity to avoid outdoor exercise. Meanwhile, as reported by the CBS 2 Chicago Website, Illinois officials designated August 9, 2005, the ninth air pollution action day this summer, and the second air pollution action day in a row. To cut down on ozone accumulation, city officials encouraged Chicago residents to use public transportation. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Terra [ http://terra.nasa.gov/ ] satellite captured this image on August 8, 2005. In this image, a layer of haze stretches southwards from the Great Lakes through the Midwest. The sharp line running diagonally through the picture is caused by different passes of the Terra satellite. The images from these passes were stitched together to make a complete picture. Because the passes occurred at different times, cloud and aerosol cover differ, but the cloud of haze persists.

Hurricane Katrina
Title Hurricane Katrina
Description Goddard Space Flight Center, Greenbelt, MD. JPL is managed for NASA by the California Institute of Technology. Images and movie courtesy of NASA/GSFC/LaRC/JPL, MISR Team. 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. The still images each cover an area of about 827 kilometers by 380 kilometers, and the animation covers an area of about 202 kilometers by 214 kilometers. The data products were generated from a portion of the imagery acquired during Terra orbit 30280 and utilize data from blocks 69 to 74 within World Reference System-2 path 17. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Science Mission Directorate, Washington, DC. The Terra satellite is managed by NASA's, This image and animation from NASA's Multi-angle Imaging SpectroRadiometer (MISR) show the strong convective development of Hurricane Katrina on Saturday, August 27, as it moved west through the Gulf of Mexico. Over 7 minutes during which all 9 MISR cameras viewed Katrina, the animation captures the cloud-top sides, the counterclockwise rotation of the eyewall, and the bubbling growth of the towering cloud structures. At this time, Katrina was undergoing rapid development— it had just been upgraded to a Category 3 hurricane, and within 24 hours it would reach Category 5. On Monday morning when the eyewall made landfall over the United States, it was a Category 4 storm. Hurricane Katrina was one of the most powerful and destructive storms on record for the Atlantic Basin. The image above is a false-color view (near-infrared, red, and blue wavelengths of reflected light displayed as red, green and blue) from MISR's nadir (pointing straight down) camera. In the image above, north is up. The high resolution image linked above shows a wider view of this false-color image, with north to the left. The vegetated Alabama coast in the upper left-hand corner in this high-resolution image appears in red hues. The bottom panel in the high-resolution image is a 3-D stereo anaglyph created with red band data from MISR's 70-degree-forward-viewing and 60-degree-forward-viewing cameras, displayed as red and green/blue, respectively. To observe the height variations in 3-D, you will need to use red/blue glasses. [ http://photojournal.jpl.nasa.gov/Help/VendorList.html#Glasses ]

Hurricane Wilma
Title Hurricane Wilma
Description (MISR) acquired this sequence of images and cloud-top height observations for Hurricane Wilma as it progressed across the Caribbean in October 2005. Each pair in the sequence has a photo-like view of the storm on the left and a matching color-coded image of cloud-top height on the right. Cloud-top heights range from 0 (purple) to 18 (red) kilometers altitude. Areas where cloud heights could not be determined are shown in dark gray. The pair on the left shows Wilma on Tuesday, October 18, when Hurricane watches were posted for Cuba and Mexico. The central pair shows the eye of Hurricane Wilma just hours before the storm began to cross the Yucatan Peninsula on Friday, October 21. At that time, Wilma was a powerful Category 4 Hurricane on the Saffir-Simpson scale, and had a minimum recorded central pressure of 930 millibars. Hurricane Wilma surged from tropical storm to Category 5 hurricane status in record time, but the storm slowed and weakened considerably after battering Mexico's Yucatan Peninsula and the Caribbean. The right-hand image pair displays the eastern edges of a weakened Wilma, when Wilma had been reduced to Category 2 status and was just starting to reach southern Florida on the morning of Sunday, October 23. Wilma gathered speed and strengthened on Sunday night, crossing Florida as a Category 3 storm on Monday, October 24. On the 18th, Wilma looked a bit ragged. Its eye is located at the center of the left edge, and its outer bands of clouds appear to be dominated by a rather loose collection of thunderstorms. In the photo-like images, these look like areas of "boiling clouds," and in the cloud-height image, these appear as orange blobs, sometimes topped with pinkish-red. On October 21 (center), when Wilma was a Category 4 storm, cloud-top height on the eastern side of the storm near the eye reached 18 kilometers in altitude, with lower heights on the western side. The image from the 23rd shows the eastern edge of Wilma as it approached Florida (upper right) and Cuba (center right). MISR has nine different cameras that view the Earth from a variety of angles. Shifts in the clouds' apparent position from one camera's perspective to another's allows MISR to measure the height of the cloud-tops. MISR scientists have programmed computers to compare the different views, identify features that appear to shift from view to view, and use that information to calculate cloud height automatically. The height fields pictured have not been corrected for the effects of cloud motion. Wind-corrected heights (which have higher accuracy but sparser spatial coverage) are within about 1 kilometer of the heights shown here. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously, viewing the entire globe between 82° North and 82° South latitude every nine days. Each image covers an area of about 380 kilometers by 1,830 kilometers. The data products were generated from a portion of the imagery acquired during Terra orbits, 31037, 31081 and 31110, and utilize data from within blocks 68-83 within World Reference System-2 paths 13, 16 and 18, respectively.

MODIS Image Shows Below-Aver …
Title MODIS Image Shows Below-Average Snow Cover in North America
Description The winter of 1999/2000 brought relatively little snow cover to the North American continent. This MODIS eight-day composite map shows the maximum snow cover in North America during the period from March 5-12. When compared to the snow extent during average years, it is apparent that there was significantly less area covered by snow this year for each month from November through April. In this image, the areas covered by snow are colored white, the non-snow covered land surface is colored green, those regions obstructed by clouds appear as grey, and water is blue. The red line represents the "average" March snow line, and the yellow line represents the "average" February snow line, as determined from NOAA/NESDIS snow maps (1966-present). Note that the snow line in March of 2000 is considerably farther north than the average February or March snow lines. By February, scientists reported that water levels in the Great Lakes--the world's largest inland bodies of fresh water--were much lower than normal. Lakes Michigan and Huron were 18 inches below average, and Lakes Superior and Erie were 9 inches below average. From 30 to 40 percent of these lakes' annual water supply comes from melting snow, the lack of which is contributing to the lower water levels. A concern is that the paltry snowpacks of this past winter, combined with high evaporative rates this coming summer, could result in the lowest lake levels on record. By the time these data were acquired, the snow line had retreated into southern Canada, but in the continental U.S., the Rocky Mountains, Cascades, Coast Range, and Sierra Nevada were still covered by snow, as were other isolated areas in the western states. Additionally, there was a band of snow spanning parts of Ohio, Indiana, Illinois, and Missouri. This band of snow was quite short-lived, lasting only a day or so, but was captured by MODIS because of its frequent coverage. The smaller extent and earlier northward retreat of the snow cover during this past winter has led to an earlier drying of the soils in many areas, which has contributed to the large number of wildfires so far this year. MODIS flies aboard the Terra spacecraft, launched in December 1999. The sensor first opened its doors and began acquiring data on Feb. 24, 2000. The MODIS sensor and Terra mission are managed by NASA's Goddard Space Flight Center. Image data courtesy Dorothy Hall, Nick DiGirolamo, George Riggs, and Janet Chien - MODIS Land Science Team
Fires Scorch Oregon
Title Fires Scorch Oregon
Description Continuing hot, dry weather is challenging firefighters in the West. This Moderate Resolution Imaging Spectroradiometer (MODIS) image from July 30, 2002, shows heavy smoke billowing from multiple large wildfires in central and southwestern Oregon (upper left). Burning in a roughly north to south line, the Florence and Sour Biscuit Fire in the Illinois River Valley region of southwestern Oregon are among the largest, and the latter has crept over the California state line and continues to burn southward. These two fires alone have burned over 96,000 acres. Eleven additional large fires are burning elsewhere in the state. In southern California, east of the fertile San Joaquin Valley, the McNalley Fire (southwest of image center) continues to grow and threaten hundreds of residences as well as 11 of the ancient Giant Sequoia Groves in the southern Sierra Nevada Mountains. Between Monday morning (July 29) and Tuesday evening (July 30), the fire grew from 73,000 to 83,000 acres and came within 2 miles of one of the Sequoia Groves. According to reports from the USDA Forest Service, the fire is expected to spread significantly to the east and north over the coming days.

The Mississippi River rose up to 12 feet above flood stage in the area shown here. Southeast Missouri and northern Arkansas, which are west of the great river, felt the brunt of the floods. Altogether, more than 50 counties in the state of Missouri reported flood damage. Farther north in Illinois, Gov. George Ryan declared the entire state a natural disaster area. Severe floods also occurred to the east in Kentucky, Ohio, and Indiana. Normally, all the rivers in this image would resemble thin black lines (left image). Though skies in the region are clear now, thunderstorms are forecast for later this week, and heavy rains could lead to continued flooding.

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.
