Title Hurricane Katrina Erodes the U.S. Gulf Coast
Description Gulf Coast cities weren't the only land surfaces to take a beating from Hurricane Katrina in August 2005. Barrier islands stretching from Texas to Florida were also scoured by the wind and waves of the powerful storm. Permanent changes to the shape and elevation of Timbalier Island and its northeastern companions are visible in this pair of infrared-enhanced images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite. Timbalier Island, the largest island pictured here, sits at the interface between the Gulf of Mexico (south) and Terrebonne Bay (north) along the Louisiana coast southwest of New Orleans. Compared to the image from 2000 (bottom), a large swath of bright sand dominates the eastern side of Timbalier Island in the September 13 image, having either been piled there or exposed by waves and storm surge. To the east-northeast, two small, curving islands have disappeared completely, while farther north, the fierce seas turned two small slots in a barrier island into a single large gap.

Hurricane Rita
Title Hurricane Rita
Description Rita was building into an extremely dangerous Category 5 hurricane when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image at 12:10 p.m., U.S. Eastern time on September 21, 2005. The storm bears the markings of a powerful hurricane: it is compact and circular, with an open eye through which the deep blue waters of the Gulf of Mexico are visible. At the time this image was acquired, Rita had winds of 220 kilometers per hour (140 miles per hour) with gusts to 270 kph (170 mph). Within a few hours, the storm intensified to a Category 5 hurricane with sustained winds of 265 kph (165 mph). Rita is the second Category 5 storm of the 2005 Atlantic hurricane season. The first was Hurricane Katrina, which devastated much of the Mississippi, Louisiana, and Alabama shoreline when it came ashore on August 29. Rita is expected to weaken slightly before coming ashore over the Texas or Louisiana coastline on September 23 or 24 as a major hurricane (Category 3 or higher). In this photo-like image, the Gulf Coast of the United States frames the open water to the north, while the Yucatan Peninsula is visible to the south. MODIS detected several fires, marked with red dots, burning in the southeastern United States. The fires are probably agricultural fires. The large image has a resolution of 500 meters per pixel. It is available in additional resolutions, including MODIS' maximum resolution of 250 meters per pixel, from the MODIS Rapid Response Team.

Title Hurricane Rita Floods U.S. Gulf Coast
Description Hurricane Rita pummeled the Louisiana and Texas shoreline when it came ashore on September 24, 2005. Though the Category 3 storm spared major cities, it left much of the southwestern and central Louisiana shoreline under water. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image of the floods on September 25, 2005. The trailing edge of Rita's clouds, light blue and white in this false-color image, still cover the region. The shoreline resembles a line of barrier islands fringing a large bay more than the solid coast that existed four days earlier, lower image. Many of the communities most severely affected by the storm are shown in these images, including hard-hit Lake Charles and Cameron, Louisiana. Lake Charles isn't clearly visible under the clouds, but traces of dark blue beneath the clouds hint at flooding in the region. Cameron and other coastal communities like Pecan Island and Grand Chenier (located on the shore just east of the plume of smoke seen in the lower image) appear to be almost entirely under water. Offshore, sediment swirls in the waters of the Gulf of Mexico, coloring the water blue in contrast to its normal inky black. The sediment is probably a combination of sludge stirred up from the ocean floor when Rita's winds and rains churned Gulf waters and run-off from the extensive flooding seen in this image. The large images provided above are at MODIS' maximum resolution of 250 meters per pixel. The MODIS Rapid Response Team provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA7 ] of the region in a variety of resolutions.

Smoke from Alaska Fires
Title Smoke from Alaska Fires
Description Smoke from large forest fires in Alaska has made the rounds across several parts of the Northern Hemisphere since the fires began in mid-June 2004. The plumes of grayish-yellow smoke have drifted across Canada and out to the Atlantic, southward to Louisiana and the Gulf of Mexico, and eastward over the Bering Strait to Russia. In this scene, smoke from fires located in the top center of the scene, in east-central Alaska, is spreading southward along the western arc of the Alaska Range Mountains and the Alaska Peninsula. Below and to the left of center, the smoke breaks eastward across the mountain barrier and streams out over the Gulf of Alaska in two parallel paths?north and south of Kodiak Island. The smoke is getting swirled into a counter clockwise-spinning region of low atmospheric pressure in Gulf. This image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Terra satellite on August 29, 2004.

Title Smoke from Alaskan Fires over Louisiana
Description This image of the southern United States from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite is a picture-perfect example of what meteorologists mean when they describe the atmosphere as a fluid. In the center of the image, an airborne river of smoke from fires raging across Alaska is flowing down the Mississippi River corridor and spreading out across the shoreline of the Gulf of Mexico, at the bottom of the scene. Thick smoke hangs over Louisiana (bottom center) as well as Texas, to the west, and Arkansas to the north. MODIS captured the image on July 19, 2004.

Tropical Storm Allison
Title Tropical Storm Allison
Description The Atlantic Hurricane Season officially began June 1 and almost on cue Tropical Storm Allison formed June 5 in the northwest Gulf of Mexico. A slow-moving storm with sustained winds around 60 miles per hour (97 km per hour), Allison made her way steadily northwestward toward Galveston, Texas. Quite extensive in her reach, Allison packed tropical storm-force winds up to 90 miles (145 km) from the center of the storm. Like an uninvited guest who doesn't know when to leave, Allison is still hanging around a week after she formed, still drawing in moisture from the Gulf and thoroughly soaking the Gulf Coast states from Texas to Florida. In Houston, Texas, Allison dropped as much as 25 inches of rain over the weekend. She dropped another two feet of water in many parts of southern Louisiana. The storm has caused at least 20 fatalities, due to the flooding, high winds and one caused by lightning. In southeastern Texas, roughly 3,500 homes have been damaged by flood waters and many counties have been declared disaster areas. Officials estimate the damage in Texas alone will exceed $1 billion. In this true-color image acquired on June 11 by the Moderate-resolution Imaging Spectroradiometer [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://modarch.gsfc.nasa.gov/ ] (MODIS), flying aboard NASA's Terra [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://terra.nasa.gov/ ] satellite, the storm center appears to be located over the Mississippi-Alabama border. Allison continues to move slowly toward the northeast. Today (June 12) her effects are still being felt in the southeastern states of Louisiana, Mississippi, Alabama, Georgia, Florida, and the Carolinas. Meanwhile, the hurricane forecast team at Colorado State University, led by professor William Gray, revised its prediction for the Atlantic Hurricane season. They expect there will be 12 tropical storms this year (up from their original estimate of 10), 7 hurricanes (up from 6), and 3 major hurricanes (up from 2).

Title Tropical Storm Bertha in the Gulf of Mexico
Description Now downgraded to a tropical depression, Tropical Storm Bertha can be seen at full strength in this true-color image taken on August 4, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS), flying aboard NASA?s Terra spacecraft. Originating in the Gulf of Mexico, the tropical storm touched land 20 miles (32 kilometers) south of New Orleans, Louisiana, which is covered by clouds in the above image. The storm continued northeast into Mississippi and Alabama, dumping up to five inches of rain in some areas and generating gusts of up to 30 miles (48 kilometers) per hour. Other than the flooding of neighborhood streets, the storm caused no damage. Image courtesy Jesse Allen, NASA Earth Observatory, data provided by MODIS Land Rapid Response Team at NASA GSFC

Title Tropical Storm Bertha in the Gulf of Mexico
Description Remnants of Tropical Storm Bertha dumped heavy rains across parts of Louisiana and Mississippi on August 5, 2002. As much as 6.73 inches of rain fell in Pascagoula, Miss., according to news reports. Meanwhile, another tropical depression formed off the coast of South Carolina on Aug. 5 and is gathering strength. As of Aug. 6, the storm had maximum sustained winds of 35 mph, just 4 mph short of becoming a tropical storm, and was moving slowly eastward. If it continues to intensify, it will become Tropical Storm Cristobol. Elsewhere in this scene, a widespread pall of haze can be seen spanning from Arkansas and Missouri across Tennessee and Kentucky, and into Ohio, West Virginia, and Maryland. Many of these regions received Code Red air quality warnings. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC

Title Flooding in the Aftermath of Hurricane Katrina
Original Caption Released with Image These views of the Louisiana and Mississippi regions were acquired before and one day after Katrina made landfall along the Gulf of Mexico coast, and highlight many of the changes to the rivers and vegetation that occurred between the two views. The images were acquired by NASA's Multi-angle Imaging SpectroRadiometer (MISR) on August 14 and August 30, 2005. These multiangular, multispectral false-color composites were created using red band data from MISR's 46° backward and forward-viewing cameras, and near-infrared data from MISR's nadir camera. Such a display causes water bodies and inundated soil to appear in blue and purple hues, and highly vegetated areas to appear bright green. The scene differentiation is a result of both spectral effects (living vegetation is highly reflective at near-infrared wavelengths whereas water is absorbing) and of angular effects (wet surfaces preferentially forward scatter sunlight). The two images were processed identically and extend from the regions of Greenville, Mississippi (upper left) to Mobile Bay, Alabama (lower right). There are numerous rivers along the Mississippi coast that were not apparent in the pre-Katrina image, the most dramatic of these is a new inlet in the Pascagoula River that was not apparent before Katrina. The post-Katrina flooding along the edges of Lake Pontchartrain and the city of New Orleans is also apparent. In addition, the agricultural lands along the Mississippi floodplain in the upper left exhibit stronger near-infrared brightness before Katrina. After Katrina, many of these agricultural areas exhibit a stronger signal to MISR's oblique cameras, indicating the presence of inundated soil throughout the floodplain. Note that clouds appear in a different spot for each view angle due to a parallax effect resulting from their height above the surface. 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 410 kilometers. The data products were generated from a portion of the imagery acquired during Terra orbits 30091 and 30324 and utilize data from blocks 64-67 within World Reference System-2 path 22. 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 Goddard Space Flight Center, Greenbelt, MD. JPL is managed for NASA by the California Institute of Technology.

Title Wetlands of the Gulf Coast
Original Caption Released with Image This set of images from the Multi-angle Imaging SpectroRadiometer highlights coastal areas of four states along the Gulf of Mexico: Louisiana, Mississippi, Alabama and part of the Florida panhandle. The images were acquired on October 15, 2001 (Terra orbit 9718)and represent an area of 345 kilometers x 315 kilometers. The two smaller images on the right are (top) a natural color view comprised of red, green, and blue band data from MISR's nadir(vertical-viewing) camera, and (bottom) a false-color view comprised of near-infrared, red, and blue band data from the same camera. The predominantly red color of the false-color image is due to the presence of vegetation, which is bright at near-infrared wavelengths. Cities appear as grey patches, with New Orleans visible at the southern edge of Lake Pontchartrain, along the left-hand side of the images. The Lake Pontchartrain Bridge runs approximately north-south across the middle of the lake. The distinctive shape of the Mississippi River Delta can be seen to the southeast of New Orleans. Other coastal cities are visible east of the Mississippi, including Biloxi, Mobile and Pensacola. The large image is similar to the true-color nadir view, except that red band data from the 60-degree backward-looking camera has been substituted into the red channel, the blue and green data from the nadir camera have been preserved. In this visualization, green hues appear somewhat subdued, and a number of areas with a reddish color are present, particularly near the mouths of the Mississippi, Pascagoula, Mobile-Tensaw, and Escambia Rivers. Here, the red color is highlighting differences in surface texture. This combination of angular and spectral information differentiates areas with aquatic vegetation associated with poorly drained bottom lands, marshes, and/or estuaries from the surrounding surface vegetation. These wetland regions are not as well differentiated in the conventional nadir views. Variations in ocean color are apparent in all three views, and represent the outflow of suspended sediment from the seabed shelf to the open waters of the Gulf of Mexico. Major features include the Mississippi Delta, where large amounts of land-derived sediments have been deposited in shallow coastal waters. These deltaic environments form a complex, interconnected web of estuarine channels and extensive coastal wetlands that provide important habitat for fisheries. The city of New Orleans is prone to flooding, with about 45% of the metropolitan core situated at or below sea level. The city is protected by levees, but the wetlands which also function as a buffer from storm surges have been disappearing. 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.
