Hurricane Dennis
Title Hurricane Dennis
Description Hurricane Dennis was bearing down on the Gulf Coast of the United States on July 10, 2005, at 12:15 p.m. (16:15 UTC) when the Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov/ ] on NASA?s Terra [ http://terra.nasa.gov/ ] satellite captured this image. With winds of 135 miles per hour (217 kph), Dennis was a powerful Category 4 storm just hours away from making landfall. At the time this image was taken, the eye of the storm was about 55 miles (90 kilometers) south, southeast of Pensacola, Florida, and the storm was moving northwest at about 18 miles per hour (29 kph). The size of the storm put clouds of rain over most of the southeastern United States well before the storm came ashore. In this image, Dennis covers all of Florida, Alabama, Mississippi, and stretches over parts of Louisiana. The northern fringes of the storm appear to be over Tennessee and North Carolina. For additional information and warnings about this storm, please visit the National Hurricane Center. This image is available in additional resolutions from the MODIS Rapid Response Team.

Hurricane Katrina
Title Hurricane Katrina
Description Hurricane Katrina was sprawled across all or part of 16 states at 2:15 p.m. CDT on August 29, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image. After nearly eight hours over land, Katrina was still a Category 1 storm, with winds of 150 kilometers per hour (95 miles per hour) and stronger gusts. In this image, Katrina measures about 1,260 kilometers (780 miles) from east to west and about the same distance from north to south across its center. While most states under its clouds have only experienced rain so far, Louisiana, Mississippi, Alabama, and Florida have all been pummeled by furious winds, heavy rain, and a powerful storm surge. Katrina was a strong Category 3 storm when its eye moved ashore earlier in the day. The large image provided above has a resolution of 500 meters per pixel. The MODIS Rapid Response Team provides the image in additional resolutions, including MODIS' maximum resolution of 250 meters per pixel.

Title Hurricane Katrina Floods the Southeastern United States
Description In the wake of Hurricane Katrina, much of New Orleans is under water in the top satellite image, taken on August 30, 2005, at 11:45 a.m. CDT by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite. Early news reports say that as much as 80 percent of the city is flooded after levees failed to hold Katrina's massive storm surge back. The flooding is getting worse as water slowly seeps into the city from Lake Pontchartrain. On Saturday, August 27, 2005, New Orleans formed a tan and green grid sandwiched between the lake shore and the river in the lower image. Three days later, dark pools of water covered the eastern half of the city, and a large section of Lake Pontchartrain ballooned into the region immediately west of the city. Widespread flooding is visible elsewhere in the top image. Lake Pontchartrain and Lake Maurepas have nearly blended into a single body of water, separated only by a narrow strip of land. Dark smudges line the rivers flowing into both lakes, a sign that water covers the ground around them. The images are shown in false color to make water visible against the land. Water is black or dark blue where it is colored with mud, vegetation is bright green, and clouds are light blue and white. The large images provided above provide a broader view of the region. They show flooding along the Mississippi and Alabama coast [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13090 ], particularly around Mobile Bay and parts of coastal Mississippi. The large images are at MODIS' maximum resolution, but both the August 30 and August 27 images are available in additional resolutions from the MODIS Rapid Response Team.

Title Hurricane Katrina Floods the Southeastern United States
Description Nearly a full week after Hurricane Katrina blasted ashore over southeastern Louisiana and southern Mississippi, the clouds cleared to give the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) a clear view of extensive flooding in the wetlands southeast of New Orleans. The floods are black against bright green vegetation in these false-color MODIS images taken on September 4, top, and August 9, bottom. The floods demonstrate how coastal wetlands function to protect inland regions from the destructive storm surge unleashed during powerful hurricanes such as Katrina. The wetlands act as a sponge, soaking up water that pounds the coast during the storm. After the storm, the wetlands retain water, which is why widespread flooding is still evident six days after the storm had passed. If the wetlands had not been there, the storm surge could have penetrated much farther inland. By contrast, there were no wetlands to buffer New Orleans from Lake Pontchartrain, so the storm-churned lake was able to burst through the levees that separated it from the city. Wetlands also act as nature's "kidneys," filtering pollutants from the water. However, like kidneys, too much pollution will destroy the wetlands. If the contaminated flood water currently covering New Orleans were to be drained through the wetlands seen here, the wetlands could be damaged. Wetland loss in coastal Louisiana is a rising concern among scientists. The United States Geological Survey reports that Louisiana lost 1,900 square miles of land between 1932 and 2000, with an average 34 square miles of land disappearing every year. Though many things contribute to wetland loss, one of the primary reasons wetlands are disappearing is water use. Canals and levees prevent the regular floods along the Mississippi River that would otherwise carry sediment to the wetlands. Meanwhile, the daily ebb and flow of the ocean washes away bits of land. Since the sediment is not replaced by regular floods, the ocean gradually eats away at the wetlands until they disappear. As the top image demonstrates, without wetlands, inland cities would be more prone to storms. Though extensive flooding is evident in the wetlands, is not yet known what long-term impact Katrina had on Louisiana's wetlands. The large images provided above are at MODIS' maximum resolution of 250 meters per pixel. Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA7 ] of the region are available in a variety of resolutions.

Hurricane Rita
Title Hurricane Rita
Description Rita became a Category 5 hurricane late on September 21, 2005, with sustained wind speeds of 275 kilometers per hour (170 miles per hour), making it the fourth most powerful storm ever measured. It was easing off this strength slightly by mid-day September 22 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 12:55 p.m., U.S. Eastern time. The storm bears the markings of a powerful hurricane: it is compact and circular, though clouds have formed in the eye of the storm. This closed or "dirty" eye shape is typical of a storm which has reached its peak strength and is slackening. However, Rita remained a remarkably powerful storm. At the time this image was acquired, Rita had winds of 250 kilometers per hour (155 miles per hour) with gusts as high as 310 km/hr (195 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. The air just below the cloud banks of Rita is remarkably clear, where wind and pressure patterns caused by the storm have banked polluted air away to the north and west. The large image has a resolution of 250 meters per pixel. It is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2005265-0922/Rita.A2005265.1655 ] from the MODIS Rapid Response Team.

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 Fires Across the United States
Description This expansive image of the United States was captured by the Moderate Resolution Imaging Spectroradiometers (MODIS) on NASA?s Terra and Aqua satellites. The left hand portion of the image comes from Aqua MODIS observations captured on the afternoon of October 22, 2003, while the right hand part of the image is from Terra MODIS observations captured a few hours earlier. Several geographic regions are experiencing fires, which were detected by the sensors and are marked with red dots. At upper left, fires are still burning across the Northern Rockies, the highest concentration is in Idaho, with additional fires in Montana to its east, and southeastern Washington and northeastern Oregon, to the west. In the Southwest, fires are burning in southern California near Los Angeles (gray patch right at edge of image to the north of the Baja Peninsula), as well as in the arc of mountains running through Arizona. At top center, fires are scattered across the northern Great Plains, from North Dakota and across the United States? border into Canada. Far to the south, dozens more fires are burning in the Mississippi River Valley in Mississippi (against right edge), Louisiana (to the west) and Arkansas (north of Louisiana).

Title Fires and Haze Along U.S. Gulf Coast
Description In Louisiana and other sugarcane-producing states in the Deep South, the burning of the sugarcane fields prior to autumn harvest is a long-standing agricultural practice. Burning eliminates the non-sugar-containing parts of the plants before they are harvested, reducing harvest time and processing costs. Like other open field burning, however, there is a downside to the practice: air pollution. Because of the potential negative health impacts of the particulates and carbon monoxide released during open agricultural burning, the Environmental Protection Agency is working with the agriculture industry to develop guidelines for agricultural burning that will reduce its contribution to poor air quality. This Moderate Resolution Imaging Spectroradiometer (MODIS) image from the Terra satellite on October 3 shows a broad swath of haze across the Gulf Coast states in the southern United States. The Mississippi River Valley runs through the center of the scene in a broad tan-colored swath. Scattered fires are marked in red. Fires and resulting build-ups of haze have been occurring on and off since the remnants of Hurricane Ivan came ashore for the second time in late September. NASA image created by Jesse Allen, Earth Observatory, based on data from the Goddard Earth Sciences DAAC.

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.
