Gamma Ray Bursts May Have Ca

| Title |
Gamma Ray Bursts May Have Caused Ancient Extinctions |
| Abstract |
Scientists at NASA the University of Kansas say that a mass extinction on Earth hundreds of millions of years ago could have been triggered by a star explosion called a gamma-ray burst. The scientists do not have direct evidence that such a burst activated the ancient extinction. The strength of their work is their atmospheric modeling -- essentially a 'what if' scenario. The scientists calculated that gamma-ray radiation from a relatively nearby star explosion, hitting the Earth for only ten seconds, could deplete up to half of the atmosphere's protective ozone layer. Recovery could take at least five years. With the ozone layer damaged, ultraviolet radiation from the Sun could kill much of the life on land and near the surface of oceans and lakes, and disrupt the food chain. These scientists calculated the potential effect of ultraviolet radiation on life. Deep-sea creatures living several feet below water would be protected. Surface-dwelling plankton and other life near the surface, however, would not survive. Plankton is the foundation of the marine food chain. This visualization shows the regions of the planet most susceptible to DNA damage (shown in red) if a large gamma ray burst were to occur close to Earth.

Floods in Kansas and Missour

| Title |
Floods in Kansas and Missouri |
| Description |
According to the U.S. Geological Survey, [ http://water.usgs.gov/cgi-bin/wwdp?region_cd=ks ] the Marais des Cygnes River was 10 feet above flood stage in Ottawa, Kansas, on July 4, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image. The river is not normally visible in MODIS images. In the lower image, taken on June 8, 2007, by Terra MODIS, the river's course is defined only by the tan, plant-free land that surrounds it. But on July 4, the dark blue water of the swollen river is clearly visible. The floods along the Marais des Cygnes forced 2,000 people from their homes in Osawatomie, Kansas, reported the Kansas City Star, but by July 4, water levels on the river had started to drop. Additional flooding along the Neosho and Verdigris Rivers can be seen in the large image. These images were made with visible and infrared light to highlight the presence of water on the ground. In this type of image, water is black, though sediment may color it dark blue. Clouds are light blue and white, and plant-covered land is bright green. Bare earth is tan-pink. Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA7/2007185 ] of Kansas are available from the MODIS Rapid Response System in both false color, as shown here, and photo-like true color.

Floods in Kansas and Missouri |
| Description |
The skies over southeastern Kansas were filled with a mix of cloud and haze on July 2, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image. But beneath the clouds, the flood-swollen Neosho and Verdigris Rivers and tributaries can be seen. Normally these river rivers would be too small to be visible in MODIS images (as shown by the lower image from June 8, 2007), but on July 2, the rivers paint a wide blue ribbon across the Kansas plains. Water is normally black in this type of false-color image, which is made with visible and infrared light. On July 2, the rivers are blue partly because sediment colors the water and partly because sunlight is reflecting off the surface of the water. Clouds are light turquoise and white, plant-covered land is green, and bare earth (largely freshly planted, rectangular farm fields) is tan. Additional flooding in western Missouri is visible in the large images. By July 2, the floods had forced thousands from their homes throughout Kansas, Missouri, Oklahoma, and Texas, reported CNN. The flood-swollen Verdigris River, image center, surrounded an oil refinery in Coffeyville, Kansas, where more than 42,000 gallons of crude oil spilled into the river, said CNN. The polluted portion of the river is under clouds in this image. The storms and the flooding in Kansas led President Bush to declare a major disaster in the state, CNN added. The Neosho River, along the right side of the image, crested at 35 feet, 10 feet above flood stage, at its highest point on July 2, and the Verdigris reached its highest point, 49 feet, 19 feet above flood stage, in Independence, Kansas, said the National Weather Service.

Floods in Kansas and Missouri |
| Description |
Floods that started with heavy rain on June 26, 2007, still surrounded parts of Coffeyville, Kansas, on July 9, when 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 the top image. Coffeyville was flooded on July 1, when the swollen Verdigris River burst through a levee. Water swamped neighborhoods and businesses, including the Coffeyville Resources Refinery. Though the refinery had been shut down in anticipation of the flooding, it leaked more than 42,000 gallons of crude oil into the Verdigris River, reported the Environment News Service. [ http://www.ens-newswire.com/ens/jul2007/2007-07-03-01.asp ] The Environmental Protection Agency [ http://www.epa.gov/region7/cleanup/coffeyville/index.html ] was coordinating with Coffeyville Resources to clean up the spill and to ensure that oil did not contaminate drinking water downstream. In these false-color images, the city of Coffeeville is silver and white. Vegetation is red, bare earth is pale gray, and water is dark blue. The Coffeyville Resources Refinery is the concentrated mass of silver, accented with large, white circular storage tanks, northeast of the city. In the top image, the refinery is surrounded by a pool of blue flood water. The lower image, taken on May 19, 2007, shows the area in normal conditions. Downstream from the refinery (to the south) is a grid of streets surrounded by plant-covered land. A few clusters of buildings line the larger streets, but few other large buildings are evident in the area, indicating that this is probably a residential neighborhood. Residual oil-tainted water creates traces of dark blue in the eastern half of the neighborhood. Smudges of blue west of the refinery indicate that the river flooded this part of the city as well. Beyond these areas, the flooded river seemed to remain confined behind levees on its flood plain. The high levees resemble dark red walls hemming in defined geometric shapes, which are filled with water in the top image, but are mud-gray in the lower image. Additional flooding along the Verdigris River is shown in the large image. A broader view [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14353 ] of floods in southeastern Kansas is available in the Natural Hazards section of the Earth Observatory.

Floods in the Midwestern United States |
| Description |
The rivers of northwestern Missouri were still swollen in the wake of intense spring storms when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image on May 10, 2007. The image is made from a combination of infrared and visible light to make the floods more visible than they would be in a photo-like image. In this type of image, water is dark blue or black, clouds are light blue and white, plant-covered land is bright green, and bare earth is pink-tinted tan. Fires are outlined with red boxes. The Missouri River runs along the left edge of the image, then curves east along the bottom of the image. Though the most flooded regions were covered in clouds, a few breaks reveal that the Missouri was swollen far beyond its banks. Nestled in a bend in the river near the Nebraska, Kansas, and Missouri border is the town of Big Lake. The image shows that the river's curve has turned into a broad lake. The town was completely submerged in the flood when levees along the river broke, reported the Associated Press. [ http://www.cnn.com/2007/WEATHER/05/11/missouri.flooding.ap/index.html ] Beyond Big Lake, many communities along the Grand and the Platte Rivers and their tributaries have also been flooded or threatened by floods. All of these rivers are clearly running high in the image. MODIS captured the lower image on April 29, 2007, not quite a week before the rains began. By providing a clear view of normal water levels, the image illustrates just how extensively the rivers were flooded on May 10. Photo-like versions of both the April 29 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA3/2007119/USA3.2007119.aqua ] and May 10 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA3/2007130/USA3.2007130.terra ] images are available from the MODIS Rapid Response System.

Early May 2007 brought torrential spring rains to the Midwestern United States, and by May 9, the National Weather Service [ http://www.nws.noaa.gov/oh/hic/ ] had recorded flooding at 111 locations from North Dakota to Texas. At 15 locations, many of which were in Missouri, gauges measured major flooding. Thousands of people fled as the Missouri burst through levees in Missouri and Kansas, reported the Associated Press [ http://www.cnn.com/2007/WEATHER/05/09/missouri.flooding.ap/index.html ] on May 9. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of floods along the Missouri River and its tributaries on May 8. Though clouds still covered much of the Midwest on May 8, a few breaks revealed the flood-swollen Missouri, Grand, and Thompson Rivers. The large image shows additional flooding in Missouri, Iowa, and Kansas. Both this and the lower image, taken on April 29 before the rains began to fall, were made with a combination of visible and infrared light to highlight the presence of water on the ground. In this type of image, clouds are pale blue and white, water is dark blue or black, plant-covered land is green, and bare earth is tan pink. The tan and green speckled appearance of the landscape seen in the lower image is typical of agricultural land.

Growing-Season Fires in Central United States |
| Description |
Agricultural burning in preparation for the growing season was underway in the central United States at the time of this image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite on March 31, 2004. Across the dun-colored witner landscape, spring green is beginning to spread across the south-central parts of the country, including (top left to bottom) Kansas, Oklahoma, and Texas, and (top right to bottom) Missouri, Arkansas, and Louisiana. Fires have been marked with red dots in the image. The smokier fires in Arkansas may be prescribed burns on state or federal lands that are set in the spring to decrease built-up underbrush and other vegetation that could contribute to more severe wildfires later in the season. Though not necessarily hazardous, large-scale burning can have an impact on weather, climate, human health, and natural resources. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions. Image courtesy Jacques Descloitres, MODIS Rapid Response Team, NASA-Goddard Space Flight Center |

Growing-Season Fires in Central United States |
| Description |
Agricultural burning continues across the Central Plains of the United States on April 4, 2004. The fires, detected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite have been marked with red dots in this image. The fires are concentrated in Kansas and Oklahoma (top left and bottom left), with additional fires in Missouri and Arkansas (top right and bottom right). The widespread nature of the fires and their location (generally located away from remaining natural vegetation, which appears deeper green) suggests that these fires are being set intentionally for agricultural purposes. Though not necessarily hazardous, such large-scale burning can have an impact on weather, climate, human health, and natural resources. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions. Two large rivers flow from west to east across the scene. The Missouri River runs out of Kansas into Missouri through Kansas City, which sits right on the border of the two states. To the south, the Arkansas River flows out of Oklahoma into Arkansas where it weaves between the Boston Mountains, which appear reddish brown, and the Ouachita Mountains, whose ridges are deep brown and punctuated by green valleys.

By January 7, 2007, Colorado had endured three major snowstorms in as many weeks. The first [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14054 ] storm arrived on December 20. The second arrived on December 28, and the third struck on January 5. According to Denver's Channel 4 news station snow totals for the second storm [ http://cbs4denver.com/weatherblog/local_blogentry_363165702.html ] ranged from 15 to 70 centimeters (6 to 27.5 inches), and for the third storm [ http://cbs4denver.com/weatherblog/local_blogentry_005213333.html ] ranged from 9 to 37 centimeters (3.5 to 14.6 inches). The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image on January 7, 2007. In this relatively cloud-free image, nearly the entire state of Colorado is buried under a blanket of snow. Only a small patch in the southwest corner of the state remains relatively dry. Snow cover extends well into Kansas and Nebraskanot surprising as the weekly snowstorms moved off in that direction. The metropolitan Denver area appears as a pale gray patch where buildings and paved surfaces interrupt the snow cover. Likewise, the mountains to the west of Denver carve meandering lines in the snow cover. The western portion of the state generally saw less snowfall than the eastern plains. As of January 8, 2007, a fourth weekly storm was predicted to hit the area a few days later. Added to the snow were high winds, with gusts up to 185 kilometers (115 miles) per hour creating snowdrifts up to 1.2 meters (4 feet) high on the roads between Denver and Boulder, home to the University of Colorado. The drifts trapped some drivers for hours. According to the Rocky Mountain News, another unlucky group of drivers were buried in their cars when an avalanche covered part of U.S. Highway 40 in the Colorado mountains on January 6, 2006.

Heatwave in the Western United States |
| Description |
The oppressive heat that crept over parts of the western United States during the first few days of July 2007 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14380 ] took hold of the entire West during the week of July 4 through July 11. Deep red tones blanket every western state in this land surface temperature image, an indication that temperatures were warmer than in previous years. The image was made with data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite and shows temperatures recorded between July 4 and July 11, 2007, compared to the average of temperatures observed during the same period in 2000, 2001, and 2002. Areas that are warmer than during that three-year period are red, while cooler areas are blue. Triple-digit temperatures broke or matched records from Las Vegas, Nevada, to Great Falls, Montana, during this period. In this image, a cluster of red-black over eastern Washington, northern Idaho, and eastern Montana indicates that these regions experienced much warmer temperatures than in previous years. Western South Dakota (the Black Hills region) was also exceptionally warm. On the other end of the scale, Texas was much cooler than it had been in 2000, 2001, and 2002. Heavy rains pounded Texas on and off throughout this period, contributing to wide-spread flooding.

Heatwave in the Western United States |
| Description |
Extreme heat lingered over much of the western United States in early July 2007. Temperatures soared to triple digits, meeting or breaking records from Las Vegas, Nevada, to Great Falls, Montana, said news reports. The oppressive heat contributed to creating prime fire conditions, so that, when dry thunderstorms (lightning storms accompanied by little or no rain) rolled through on July 7, lightning sparked dozens of fast-moving wildfires. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14358 ] This image, created from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite from June 26 though July 3, 2007, shows land surface temperatures compared to average temperatures observed during the same period in 2000, 2001, and 2002. Deep red across the Southwest and the Intermountain West indicate that temperatures were much higher than they were in 2000-2002. The Southeast also experienced warmer temperatures. Northern California, Oregon, and Washington appear to be cooler than in previous years, as indicated by the blue tones. The heat wave started mid-way through the week-long period shown in this image. While temperatures may have soared at the end of the period, cooler temperatures earlier in the week dominate the signal. Land surface temperatures from July 4-11 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14393 ] show that these areas warmed significantly the following week. The Southern Plains are dark blue where temperatures were much cooler than they had been in previous years. During this period, torrential rains drenched the region, causing wide-spread flooding in Texas and Oklahoma [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14363 ] and in Kansas and Missouri. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14383 ] The gray region over Kansas and Oklahoma is an area in which MODIS could not record the land's temperature because of perpetual cloud cover during the week-long period.

The reddish-orange bull's-eye over southeastern Louisiana is evidence of the torrential rains that pounded visitors to the annual New Orleans Jazz Festival. South-central Texas' Edward Plateau was soaked with more than 240 millimeters of rain during the period, as well. From May 4 to May 8, the National Weather Service [ http://www.nws.noaa.gov/ ] received approximately 683 reports of severe weather, 140 of which were reports of tornadoes, including the massive F5 [ http://www.crh.noaa.gov/crnews/display_story.php?wfo=ddc&storyid=7828&source=0 ] tornado that devastated the city of Greensburg, Kansas. Beyond the damaging winds and tornadoes, the torrential rain triggered extensive flooding throughout the Central Plains. On the evening of May 7, flood warnings [ http://www.crh.noaa.gov/crnews/display_story.php?wfo=crh&storyid=7865&source=0 ] were in effect from South Dakota to southern Texas, and by May 8, the Hydrologic Information Center [ http://www.weather.gov/ahps/ ] reported moderate to major flooding at 53 stream gauge sites in South Dakota, Iowa, Kansas, Nebraska, Missouri, and Arkansas.

Killer Storms in the southern Plains and the Southeast |
| Description |
*animations: * small movie (848 KB) large movie (2.8 MB) Severe thunder storms formed over the midwestern United States on May 4, 2003, and spawned dozens of tornadoes that swept through parts of Kansas, Missouri, Arkansas, and Tennessee, leaving a wake of destruction and killing as many as 35 people. Eighty-three tornadoes were reported, according to an official with the Federal Emergency Management Agency, but the official count has not yet been confirmed. Pierce City, MO, was among the locations hardest hit. Residents of the small town in southwestern Missouri report that almost every structure in the townhouses and businesses alikewere flattened in a span of about 30 seconds by the tornado that roared through there. After forming late in the day over southeastern Kansas and Missouri, the line of thunder storms moved quickly eastward. Much of the damage appears to be along the Kansas-Missouri border. One official with the National Weather Service estimates that the storm that ripped through Pierce City was at least a Category F3 tornadopacking winds between 158 and 206 miles per hour. Eastern states have been put on alert as the storm system moves toward the southern states, bringing the potential for more tornadoes to occur in Kentucky, eastern Tennessee, and northern Georgia. The image above was acquired by the NOAA GOES-12 satellite on May 4. The time series animation shows cloud tops of the storm system forming over southeastern Kansas and Missouri and then moving eastward as night falls.

Killer Storms in the southern Plains and the Southeast |
| Description |
TRMM Eyes Great Plains Severe Thunderstorms On Sunday, May 4, a super outbreak of tornadoes and severe thunderstorms swarmed across the southern Plains region of the United States. According to the Storm Prediction Center, there were 275 reports of large hail, 89 reports of wind damage and 84 tornadoes. On this day, 187 tornado warnings were issued across Tennessee, Arkansas, Missouri, Kansas, Oklahoma, North Dakota and South Dakota. The Tropical Rainfall Measurement Mission, which contains the world's only spaceborne weather radar, overflew several of these deadly thunderstorm cells late on May 4. The image shows the white, cloudy tops of several thunderstorm cells from the vantage of the GOES satellite. The TRMM orbit (dark shading) is superimposed on this cloudy background. There is a particularly intense storm cell located over western Oklahoma (left side of image). Whereas the GOES satellite shows this to be a single, isolated storm, the TRMM precipitation radar reveals that it is actually composed of three smaller precipitation cores in various stages of development. The vertical scale of the rain features has been greatly exaggerated to show details. The dark blue colors correspond to the tallest rain cells (approaching 15-16 km depth) while red colors indicated shallower rain features. This particular "multicell" storm produced damaging hail as it moved from west to east across Oklahoma.

Severe Weather in the US Midwest |
| Description |
A stationary front draped across the Midwest provided the focus for several days of strong springtime thunderstorms that delivered severe weather and heavy rains to the region. On May 21, 2004, a strong complex of thunderstorms known as an MCS or mesoscale convective system moved across southern Michigan, Ohio and into parts of the Appalachians leaving behind numerous reports of wind damage. Long-lived MCSs that generate wind damage over a wide area are also known as 'derechos' as was the case for this event. On May 22, there were numerous reports of tornados from Nebraska into Iowa. One woman was killed in Nebraska, and the town of Hallam, Nebraska was flattened by a tornado. On May 23, two children were swept away in Wisconsin as runoff from heavy rains drained into the Milwaukee river. And on May 24, there were more tornados, large hail and wind damage across parts of Iowa, Kansas, Missouri, and Illinois. In addition to tornados, hail and wind damage, strong thunderstorms can produce heavy rains and flooding especially when storms occur over the same area. The Tropical Rainfall Measuring Mission satellite uses onboard sensors to measure rainfall from space. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global tropics. MPA rainfall totals are shown for May 21-24, 2004 over the Midwest. Red areas indicate rainfall totals in excess of 10 inches across portions of northern Iowa, southern Minnesota, Wisconsin, eastern Michigan, northeast Ohio and southeast Ontario. Areas in between shaded in green received near 5 inches. TRMM is a joint mission between NASA and the Japanese space agency JAXA.

A thick cloud of aerosols hung over part of North America on March 12, 2006. Aerosols, tiny particles suspended in the atmosphere, can result from a variety of sources, including dust storms, pollution, and smoke. This aerosol cloud, extending from northern Mexico through Kansas, likely resulted in a large part from fires [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13411 ] in Texas and Oklahoma. Windy conditions that helped spread some wildfires might also have lofted dust particles into the air. The Ozone Monitoring Instrument (OMI) [ http://aura.gsfc.nasa.gov/instruments/omi/index.html ] flying onboard the Aura [ http://aura.gsfc.nasa.gov/index.html ] satellite captured this image on March 12, 2006. This false-color image shows the thickness of dust, smoke, or pollution in the atmosphere. The most intense aerosol concentrations appear in bright red, followed by yellow and green. A band of thick aerosols appears just south of a large swath of cloud cover (appearing in white) in the Midwestern United States. This aerosol cloud, stretching from the New Mexico-Mexico border northeast into Kansas, shows patches of high concentrations throughout, although the biggest patches of intense aerosols appear in Oklahoma and Kansas.

Snow Across the Western United States |
| Description |
The Sunday after Thanksgiving is traditionally one of the busiest travel days of the year in the United States as people return home from the four-day weekend. Sunday, November 28, 2004, was no exception, but this year, Mother Nature snarled traffic across a large swath of the west with an intense snow storm. The storm dumped up to 24 inches (0.6 meters) of snow on the mountains of southern Utah, and blanketed the surrounding states. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image the following day, on November 29, after the clouds moved out. The storm's path is clearly visible in this image: a track of white extends from southeastern Oregon and the Sierra Nevada Mountains in California to Colorado and New Mexico in the east. The National Weather Service reports that the storm moved east across the Plains States of Nebraska, Kansas, Oklahoma, Texas, Missouri, and Iowa on November 29 and November 30. The snow highlights some interesting features of the Western United States that might not otherwise be obvious in satellite imagery. Sandwiched between the straight diagonal line of the Sierra Nevada Mountains in the west (the straight edge of the snow) and the Rocky Mountains in Central Utah in the east is the Great Basin Desert. This high desert basin covers a heart-shaped region of southern Oregon, Nevada, Utah, and southern Idaho and is clearly outlined in snow. Hemmed between two large mountain ranges that trap moisture from the east and the west, it is the United States' largest desert. It receives on average 7-12 inches of precipitation every year. The water that does fall in the region drains to interior, closed basins instead of the ocean, giving the region its name. The Great Basin Desert is made up of a series of mostly north-south running mountain ranges and valleys that give the land a wrinkled, wash-board appearance, particularly in Nevada. The snow highlights elevation change elsewhere in the image. The imposing Rocky Mountains appear slightly darker than the valleys around them, and the peaks and high plateaus in the south are covered in snow while the pink desert lowlands remain bare. On the right edge of the image, the flat plains of eastern Wyoming and Colorado are an even, uninterrupted white.

Snow Storm in Colorado

Snow Storm in Colorado |
| Description |
A big snowstorm brought much-needed moisture to the state of Colorado on January 19, 2006. As reported by the Rocky Mountain News, before the storm, the state's assistant climatologist had warned that drought was beginning to affect the foothills west of the Denver metro area and the plains to the east of the city. A week later, relief arrived, although opinions varied as to whether it was enough to stop the developing drought conditions. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Terra [ http://terra.nasa.gov/ ] satellite took this picture of Colorado and surrounding states on January 20, 2006. In this image, snow blankets the Rocky Mountains and extends to the east in a counterclockwise direction towards Kansas and Nebraska. The same storm system that brought moisture to Colorado continued dropping precipitation through the Midwest. For Colorado residents, the snow was a mixed blessing. On January 19, temperatures remained warm enough to melt much of the snow as soon as it hit the ground. Overnight temperatures, however, plummeted. The day this image was taken, commuters throughout the state were contending with roads like ice rinks. According to the Colorado Springs Gazette, authorities urged commuters to drive slowly to avoid crashes.

The Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) on the Terra [ http://terra.nasa.gov/ ] satellite tracked a blue trail of snow across northern Texas, New Mexico, and Southern Colorado on February 25. Blue patches of snow also appear in southern Utah, upper left corner. In this false-color image, the snow is blue, bare ground is pink, vegetation is bright green, and clouds are white and light blue. The states shown in this image include, starting in the upper left corner and going clockwise, Utah, Colorado, Kansas, Oklahoma, Texas, New Mexico, and Arizona.

Snowstorm in the American Midwest |
| Description |
The vernal equinox marks the start of spring in the Northern Hemisphere. But after a record-setting warm winter, the start of spring 2006 came with an ironic twist: a powerful snowstorm that blanketed most of the American Midwest in heavy snow. According to the Associated Press, snow fell as rapidly as two inches an hour in Illinois and Indiana, while in parts of Nebraska, total accumulations were as much as two feet (roughly 60 centimeters) of snow, closing sections of Interstate 80. In Colorado and Kansas, the same snow system also forced closings along Interstate 70 on March 20. The AP was also reporting that at least five deaths had been attributed to the snow in Colorado, Nebraska, and Texas. The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite observed the wake behind the storm at 12:55 p.m. Mountain Time (19:45 UTC) on March 21, 2006. In this false-color image, clouds appear white, snow and ice appear blue, and land colors vary from reddish tans to greens in areas of lesser or greater vegetation. While a thin layer of cloud covers much of the area where the heaviest snow fell the previous day, the long, wide swath of blue, occasionally visible through the thin cloud cover, shows the path of the snowstorm.

Snowstorm Rolls Across the U.S. |
| Description |
A severe winter storm rolled eastward across the central United States between December 23 and 25, 2002, bringing a white Christmas to millions of people in a wide swath stretching from the southern Great Plains region all the way to New England. Many areas in the northeast reported blizzard conditions during the storm, in which snow accumulated on the ground at a rate of up to 5 inches (12 cm) per hour. As much as 3 feet (1 meter) of snow fell in some places over the 48-hour span. Unfortunately, the storm resulted in at least 19 deaths. There have been a number of car accidents reported in many states and tens of thousands of people living in the northeast were left without power. This true-color image was acquired on Dec. 25, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS) flying aboard NASA?s Aqua satellite. The wide white swath running from west to east through the scene shows the southern Great Plains region blanketed by snow ? from the Texas panhandle across northern Oklahoma and southern Kansas into Missouri and northwestern Arkansas.

According to Denver's Channel 4 news station snow totals for the second storm [ http://cbs4denver.com/weatherblog/local_blogentry_363165702.html ] ranged from 15 to 70 centimeters (6 to 27.5 inches), and for the third storm [ http://cbs4denver.com/weatherblog/local_blogentry_005213333.html ] ranged from 9 to 37 centimeters (3.5 to 14.6 inches). The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image on January 7, 2007. In this relatively cloud-free image, nearly the entire state of Colorado is buried under a blanket of snow. Only a small patch in the southwest corner of the state remains relatively dry. Snow cover extends well into Kansas and Nebraskanot surprising as the weekly snowstorms moved off in that direction. The metropolitan Denver area appears as a pale gray patch where buildings and paved surfaces interrupt the snow cover. Likewise, the mountains to the west of Denver carve meandering lines in the snow cover. The western portion of the state generally saw less snowfall than the eastern plains. As of January 8, 2007, a fourth weekly storm was predicted to hit the area a few days later. Added to the snow were high winds, with gusts up to 185 kilometers (115 miles) per hour creating snowdrifts up to 1.2 meters (4 feet) high on the roads between Denver and Boulder, home to the University of Colorado. The drifts trapped some drivers for hours. According to the Rocky Mountain News, another unlucky group of drivers were buried in their cars when an avalanche covered part of U.S. Highway 40 in the Colorado mountains on January 6, 2006.

| Title |
Stressed Crops in Ukraine and Russia |
| Description |
Flat, fertile plains stretch northward from the Black Sea in Ukraine and southern Russia. With a climate similar to that of Kansas, roughly two-thirds of the Ukraine is agricultural land. The main crops in the region are wheat, barley, and corn. Most wheat (about 95 percent) is planted in the late fall and harvested in July and August of the following year. Across the border in southern Russia, winter wheat is similarly important. As the wheat grows, farmers rely on rain to nourish the developing plants. In 2005, however, farmers faced a problem. As of September 29, little or no rain had fallen over the region since mid-August. Without rain, farmers could not plant on time. Those who did plant faced the prospect of a poor crop unless rain began to fall. The effects of dry conditions on plants across Ukraine and southern Russia are shown in this vegetation image, made from data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) between October 2 and October 10, 2005. Dry areas are shown in brown, while normal conditions are tan, and better-than-normal conditions are green. The drought seems to be particularly bad on Crimea, the island-like peninsula in the Black Sea, and in Russia to its east, where deep red points to very stressed vegetation. The vegetation index is a measure of the amount of light absorbed by plants over a large area during photosynthesis. When crops are healthy, they produce more leaves and, as a result, absorb more light in photosynthesis. When they are stressed by drought, crops produce fewer leaves and absorb less light. In this image, the vegetation index was compared to the average of measurements made during the same period in 2001-2004. The resulting image shows that plants are significantly more stressed in 2005 than they were during this period in the previous four years. NASA image created by Jesse Allen, Earth Observatory, using data provided by Inbal Reshef and information provided by Assaf Anyamba as part of the Global Agricultural Monitoring Project between NASA, USDA's Foreign Agricultural Service (FAS), and the University of Maryland.

Fires in the Great Plains
| Title |
Fires in the Great Plains |
| Description |
Before European colonization of North America?s Great Plains, spring and summer fires, triggered both by lightning and by Native Americans who used the fires to drive game, would race across the prairies, suppressing invasion from woody plants and hastening the germination of new grass seeds. Today, the springtime fires in places such as Kansas are mostly agricultural fires. Farmers and ranchers use fire to clear last year's stubble. This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Aqua satellite on April 14, 2005, shows dozens of fires (marked in red) burning in eastern Kansas. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the MODIS Rapid Response team. |

Fires in the Great Plains |
| Description |
In the plains south of Topeka, Kansas, on April 9, 2006, the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite detected numerous fires burning. The larger image shows fires to the south in Oklahoma, as well. Marked in red in this photo-like satellite image, many of the fires are associated with dark-colored burn scars. MODIS cannot tell the cause of the fires it detects, but this area supports numerous ranches and farms and it is possible that the fires are for brush or pasture clearing. Many parts of the Great Plains and the Southern Plains have experienced significant early-season fire activity this year, however, so some of the fires may be natural or accidental wildfires. The high-resolution image provided above has a spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Fires in the Great Plains |
| Description |
In Kansas, dozens of active fires were burning when the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite passed overhead on April 12, 2006. The fires are marked in red in the scene. The tan-and green-speckled landscape is darkened by burn scars as well. Many of these fires may be intentional fires set by people to clear ranch or farmland of brush for grazing, planting, or to reduce fire danger later in the season. The high-resolution image provided above has a spatial resolution of 500 meters per pixel. The MODIS Rapid Response System provides images of this part of the United States at additional resolutions.

Fires in the Southern Midwest |
| Description |
On April 4, 2007, dozens of fires were burning in the southern portions of the U.S. Midwest. Marked with red dots in this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite, the fires are scattered across Kansas, Missouri, Arkansas, and Oklahoma. Winds are blowing nearly due south, stretching smoke plumes from several of the fires. Though much of the landscape has "greened up" with the arrival of spring, higher elevations, such as the Ouachita Mountains, are still showing winter brown. The large image provided above has a spatial resolution (level of detail) of 500 meters per pixel.

Texas Greenup

Texas Greenup |
| Description |
June 2007 was one of the wettest Junes on record for the state of Texas. Starting in late May, a string of low-pressure systems settled in over the U.S. Southern Plains and unleashed weeks of heavy to torrential rain. During the final week of June, much of Texas, Oklahoma, and Kansas received more than 330 percent of their average rainfall, said the National Climatic Data Center. [ http://www.ncdc.noaa.gov/oa/climate/research/us-weekly.php?year=2007&month=06&sat=30&submit_form=Submit&_submit_check=1#panom ] The widespread heavy rain brought deadly floods [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14350 ] to the entire region. On July 6, the Associated Press reported that every major river basin in Texas was at flood stage, an event that had not occurred since 1957. In addition to causing floods, the rains stimulated plant growth. The grassy, often arid, plains and plateaus of northern Mexico (bottom left), Texas (center), and New Mexico (top, left of center) burst to life with dense vegetation as this vegetation anomaly image shows. Regions where plants were growing more quickly or fuller than average are green, while areas where growth is below average are brown. Most of Texas is green, with a concentrated deep green, almost black, spot where vegetation growth was greatest. This area of western Texas is where the Pecos River flows out of New Mexico and heads southeast to the Rio Grande. In the darkest areas, vegetation was more than 100 percent above average. The brown spots in northeastern Texas and Oklahoma (top, right of center) may be areas where persistent clouds or water on the ground are hiding the plants from the satellite's view. Plants may also be growing less than average if swamped by too much rain. The image was made with data collected by the SPOT satellite between June 11 and June 20, 2007. NASA imagery created by Jesse Allen, Earth Observatory, using SPOT data provided courtesy of the USDA Foreign Agricultural Service and processed by Jennifer Small and Assaf Anyamba of the GIMMS Group [ http://ltpwww.gsfc.nasa.gov/gimms/htdocs/ ] at NASA GSFC. |
