Title Floods in the Midwestern United States
Description Water levels on the Blanchard River in northwestern Ohio reached near-record levels a short time after the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image at 12:30 p.m. Eastern Daylight Time, on August 22, 2007. 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. These images are shown at MODIS' maximum resolution of 250 meters per pixel. Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA3/2007234 ] of the U.S. Midwest are available from the MODIS Rapid Response System in a variety of resolutions.

Title Floods in the Ohio River Valley
Description A small break in the clouds on January 9, 2005, provided the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying aboard NASA?s Terra [ http://terra.nasa.gov/ ] satellite a peek at the swollen rivers of the Ohio River Valley in the Central Lowlands of the United States. Winter weather has pushed the Ohio River and many of its tributaries past flood stage. In the above MODIS image, the Ohio River, Wabash River, White River and the East Branch White River are all swollen compared to conditions on December 17, 2004, shown in the lower image. A false-color band combination has been used to make the flood waters more apparent. In both images, water is dark blue and black, clouds are light blue and white, vegetation is bright green, and bare earth is pink.

Floods in the U.S. Midwest
Title Floods in the U.S. Midwest
Description *Floods in the U.S. Midwest* Heavy rain and snow on January 4 and 5, 2004, have left swollen rivers throughout the U.S. Midwest. 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.

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

Title Flooding along the Mississippi
Description *large images:*  April 25, 2002 (1.8 MB JPEG)  May 18, 2002 (2.3 MB JPEG) Over the past two weeks, heavy rains gave rise to floods all across the midwestern United States, killing 8 people and forcing many more from their homes. These false-color images show the junction of the Ohio River and the Mississippi River where the flooding was at its worse. The images compare April 25, 2002, to May 18, 2002, with data from the Moderate-resolution Imaging Spectroradiometer [ http://modarch.gsfc.nasa.gov/ ] (MODIS), flying aboard NASA's Terra [ http://terra.nasa.gov/ ] spacecraft. 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. In these false-color images, green shows bare land surface and black is water. The orange-brown shades show vegetated areas and the pinkish-white patches are clouds.

Title Spring in Southeastern Illinois and Central Indiana
Original Caption Released with Image 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., Vegetation across southeast Illinois and central Indiana is shown in this set of multispectral and multiangle images from the Multi-angle Imaging SpectroRadiometer (MISR). Across the center of the image area, the Wabash River runs southward, and in some places corresponds with the Illinois-Indiana border. The White River flows through the city of Indianapolis (to the right of image center), and into Monroe Lake (a dark-colored reservoir at bottom-right). The majority of these fertile lands are used to grow crops, with woodlands present along the rivers and in the rolling hills of South Indiana, indicated in the lower right-hand portion of the images. The top-left panel is a natural color image from MISR's nadir camera, and the top-right panel is false-color image, also from MISR's nadir camera, but displaying data from MISR's near-infrared, red and green bands as red, green and blue, respectively. Living vegetation is highly reflective at near-infrared wavelengths and so appears in red hues in the false-color image. The lower-left panel is a multi-angular composite in which data from the red band of MISR's 46 backward, nadir, and 46 forward viewing cameras are displayed as red, green and blue, respectively. The lower-right panel displays near-infrared band data in the same configuration from the same cameras. Color variations in the angular composites serve as a proxy for changes in angular reflectance, which are in turn influenced by the vegetation structure, terrain, soil type, and the solar illumination conditions. When MISR captured this image on April 5, 2004, areas with strongest near-infrared reflectance corresponded with wooded areas, or with the perimeters of cities, while the croplands on the Illinois side of the Wabash River had yet to undergo vigorous springtime growth. On the Indiana side of the Wabash River, a large tract of forested land is situated about 70 kilometers south of Indianapolis, and appears in dark green hues in both the red and the near-infrared angular composites, indicating that it is more reflective in the nadir view than at the off-nadir angles. This can occur if the underlying soil is brighter than the vegetation at both wavelengths. However, many forested areas that appear in dark green hues in the red-band angular composite exhibit more neutral tones in the near-infrared angular composite. This suggests greater near-infrared reflectivity in the nadir view in those areas, possibly due to enhanced abundance of understory vegetation. The Multiangle Imaging SpectroRadiometer 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 orbit 22868. The panels cover an area of about 235 kilometers x 170 kilometers, and utilize data from blocks 58 to 59 within World Reference System-2 path 22. MISR was built and is managed by NASA's Jet Propulsion Laboratory,
