Description This space radar image illustrates the recent rapid urban development occurring along the lower Colorado River at the Nevada/Arizona state line. Lake Mohave is the dark feature that occupies the river valley in the upper half of the image. The lake is actually a reservoir created behind Davis Dam, the bright white line spanning the river near the center of the image. The dam, completed in 1953, is used both for generating electric power and regulating the river's flow downstream. Straddling the river south of Davis Dam, shown in white and bright green, are the cities of Laughlin, Nevada (west of the river) and Bullhead City, Arizona (east of the river). The runway of the Laughlin, Bullhead City Airport is visible as a dark strip just east of Bullhead City. The area has experienced rapid growth associated with the gambling industry in Laughlin and on the Fort Mojave Indian Reservation to the south. The community of Riviera is the bright green area in a large bend of the river in the lower left part of the image. Complex drainage patterns and canyons are the dark lines seen throughout the image. Radar is a useful tool for studying these patterns because of the instrument's sensitivity to roughness, vegetation and subtle topographic differences. This image is 50 kilometers by 35 kilometers (31 miles by 22 miles) and is centered at 35.25 degrees north latitude, 114.67 degrees west longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations as follows: red is L-band, horizontally transmitted and received, green is L-band, horizontally transmitted and vertically received, and blue is C-band, horizontally transmitted and vertically received. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR- C/X-SAR) on April 13, 1994, onboard the space shuttle Endeavour. SIR-C/X-SAR, a joint mission of the German, Italian and United States space agencies, is part of NASA's Office of Mission to Planet Earth. #####

Title National Map Showing Habitat Suitability for Tamarisk Invasion
Abstract The spread of invasive species is one of the most daunting environmental, economic, and human-health problems facing the United States and the World today. It is one of several grand challenge environmental problems being addressed by NASA's Science Mission Directorate through a national application partnership with the US Geological Survey. NASA and USGS are working together to develop a National Invasive Species Forecasting System (ISFS) for the management and control of invasive species on Department of Interior and adjacent lands. The system provides a framework for using USGS's early detection and monitoring protocols and predictive models to process MODIS, ETM+, ASTER and commercial remote sensing data, to create on-demand, regional-scale assessments of invasive species likely habitats. Recent work on the Invasive Species Forecasting System (ISFS) project has shown the importance of remotely-sensed time-series data in geostatistical models for mapping the distribution of Tamarisk and other invasive plant species. This video shows the habitat suitability for a Tamarisk invasion in the continental United States. Red indicates areas that are highly suitable and yellow indicates areas which are less suitable. Texas, New Mexico, and Nevada are the most highly suitable states. Utah and Arizona have the next greatest risk. California, Arizona, Montana, Colorado, Oregon, Ohio, Wyoming, and Florida also have a significant risk.

Lake Mead Shrinks!
Title Lake Mead Shrinks!
Abstract Lake Mead reservoir is nestled between Arizona and Nevada and runs up to the Hoover Dam. The reservoir stores Colorado River water and supplies it to farms, homes and business in Southern Nevada, Arizona, southern California and northern Mexico. Scientists at NASA are releasing dramatic pictures of the dwindling water supplies in the drought-stricken western United States. According to the Bureau of Reclamation, the Colorado Basin is in its fourth year of drought and computer models project water levels will go down another 15 to 20 feet (4.6 to 6.1 m) by next year. Despite low water levels, The National Park Service says there is still plenty of water for recreation. The Landsat 7 satellite captured images of Lake Mead May 2000, and May 2003. The 2003 image clearly shows a shrinking lake.

Cloudy winter in Mexico and …
Title Cloudy winter in Mexico and the Southern United States
Description February was a cloudy and, in some places, a rainy month for much of the southern United States and Mexico. Heavy rains flooded southern California, Nevada, Utah and Arizona. This image hints at patterns of cloud cover during February. The image is a measurement of outgoing longwave radiation, the heat emitted by the Earth's surface. Clouds are cooler than land, so outgoing longwave radiation is less intense where there are clouds. The above image shows anomalies—where February 2005 differed from average values measured in February 1979-1995. Regions where there were more clouds than normal are blue, while areas with fewer clouds are red. The blue regions seen here confirm the days of rain that southern North America experienced in February. This image was derived from measurements made by the TIROS Operational Vertical Sounder (TOVS) onboard the NOAA-POES satellite series.

Heatwave in Southern Califor …
Title Heatwave in Southern California
Description September 5, 2007, marked the end of a week-long heat wave that led to 31 deaths and triggered power outages across southern California, reported the L.A. Times. Temperatures climbed above 38 degrees Celsius (100 Fahrenheit) when a high-pressure system blocked cool air from the Pacific. The effect of the heat wave on different locations in the Southwest is shown in this pair of images, taken on September 5, at 11:25 a.m. local time (18:25 UTC) by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Terra [ http://terra.nasa.gov/ ], in Northern California filters down from the top edge of the scene. NASA image created by Jesse Allen, using data obtained from the Goddard Land Processes data archives (LAADS). [ http://laads.gsfc.nasa.gov/ ], satellite. The photo-like, natural-color image (top) and corresponding land surface temperature image (bottom) illustrate the relationship between land cover, elevation, and temperature. The images show much of California and Nevada, and a smaller portion of Arizona and Utah. Not surprisingly, the hottest areas, shown in yellow, correspond with sparsely vegetated desert regions. In the natural-color image, the brush-covered Mojave Desert on the California-Nevada border is tan with splashes of pink where iron-rich sandstone is exposed. The small-leafed, woody vegetation provides little shade, allowing the Earth's surface to be exposed to the Sun. The rock-and-dirt desert absorbs sunlight, and temperatures climb (yellow areas of bottom image). The other hot spots in the image occur in the cactus-dotted Sonoran Desert, which encompasses the southernmost portions of inland California and southwestern Arizona, and the much smaller Colorado Desert west of the Salton Sea. Irrigated land south of the Salton Sea and along the Colorado River is a web of brown-green. The presence of water and vegetation in these irrigated areas makes the land cooler. Elevation also plays a role in the surface temperatures of the Sonoran Desert. Pockets of low-elevation land are much warmer than the lines of mountains that separate them, particularly in southwestern Arizona. The coolest parts of California, shown in purple and blue, are in the mountains, most prominently the Sierra Nevada, but also the San Bernardino Mountains east of Los Angeles. In the photo-like images, the mountain ranges are dark green, colored by trees. The vegetation cover and the high elevation keep the land cooler than surrounding low-elevation sites. The other significant cool spot in the image is the San Joaquin Valley. Like the irrigated farm land bordering the Salton Sea and the Colorado River, this area is kept cool by the presence of water and plants. The coldest areas in the image appear to be in Arizona, Utah, and Nevada, which are marked by streaks of dark purple. These cold signatures are from clouds.The final correlation between land cover and temperature can be seen in urban areas along the coast. In the photo-like image, Los Angles sprawls as a silver-gray patch from the coast to the San Bernardino Mountains. Since urban surfaces absorb heat, Los Angles is slightly warmer in the surface temperature image than the surrounding landscape. In the north, the San Francisco urban area is similarly warmer than its surroundings. Though the extreme temperatures raised the fire danger in Southern California, MODIS did not detect any fires in the region. Fires, marked with red dots, were burning in Central California south and east of San Francisco.

Title Drought in Southwestern United States
Description The southwestern United States pined for water in late March and early April 2007. This image is based on data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite from March 22 through April 6, 2007, and it shows the Normalized Difference Vegetation Index, or NDVI, for the period. In this NDVI color scale, green indicates areas of healthier-than-usual vegetation, and only small patches of green appear in this image, near the California-Nevada border and in Utah. Larger areas of below-normal vegetation are more common, especially throughout California. Pale yellow indicates areas with generally average vegetation. Gray areas appear where no data were available, likely due to persistent clouds or snow cover. According to the April 10, 2007, update from the U.S. Drought Monitor, [ http://www.drought.unl.edu/dm/monitor.html ] most of the southwestern United Sates, including Utah, Nevada, California, and Arizona, experienced moderate to extreme drought. The hardest hit areas were southeastern California and southwestern Arizona. Writing for the Drought Monitor, David Miskus of the Joint Agricultural Weather Facility reported that March 2007 had been unusually dry for the southwestern United States. While California's and Utah's reservoir storage was only slightly below normal, reservoir storage was well below normal for New Mexico and Arizona. In early April, an international research team published an online paper in Science noting that droughts could become more common for the southwestern United States and northern Mexico, as these areas were already showing signs of drying. Relying on the same computer models used in the Intergovernmental Panel on Climate Change (IPCC) report released in early 2007, the researchers who published in Science concluded that global warming could make droughts more common, not just in the American Southwest, but also in semiarid regions of southern Europe, Mediterranean northern Africa, and the Middle East.

Fires in the Southwest
Title Fires in the Southwest
Description The Southern Nevada Complex Fire has scorched more than 500,000 acres in the area between the White and Virgin Rivers in the U.S. Southwest. The fires in the complex were started by lightning and are burning in juniper-pinyon woodlands and grass. This image of southern Nevada (left), Utah (upper right), and Arizona (lower right), shows the huge area involved in the Southern Nevada Fire as well as numerous smaller fires burning on June 30, 2005. The image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA'a Aqua satellite. Active fire locations are outlined in red. Vegetation is bright green, naturally bare or thinly vegetated soil is tan or pink, and burned areas are deep reddish-brown.

Fires in the Southwest
Title Fires in the Southwest
Description Fire season in the U.S. West got off to a roaring start in the third week of June 2005. Fires triggered by ?dry? lightning (lightning without rain) sprang up in several Western states and grew explosively in a matter of days. In this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Aqua [ http://aqua.nasa.gov ] satellite, fires (outlined in red) are burning in California, Nevada, Utah, and Arizona. Among the largest are the Cave Creek Fire to the northeast of Phoenix, Arizona, the Good Springs Fire in Nevada, to the southwest of Las Vegas, and the Hackberry Fire in California. To read more about these fires, visit the Current Wildland Fire Information [ http://www.nifc.gov/information.html ] Webpage on the National Interagency Fire Center Website.

The Colorado River
Title The Colorado River
Description This Moderate-resolution Imaging Spectroradiometer (MODIS) true-color image shows the passage of the Colorado River through several southwestern states. The river begins, in this image, in Utah at the far upper right, where Lake Powell is visible as dark pixels surrounded by the salmon-colored rocks of the Colorado Plateau. The Colorado flows southwest through Glen Canyon, to the Glen Canyon Dam, on the Utah-Arizona border. From there it flows south into Arizona, and then turns sharply west where the Grand Canyon of the Colorado cuts through the mountains. The Colorado flows west to the Arizona-Nevada (upper left) border, where it is dammed again, this time by the Hoover Dam. The dark-colored pixels surrounding the bend in the river are Lake Mead. The river flows south along the border of first Nevada and Arizona and then California and Arizona. The Colorado River, which begins in Rocky Mountain National Park in Colorado, empties into the Gulf of California, seen at the bottom center of this image.

Fires Scorch Oregon
Title Fires Scorch Oregon
Description Throughout the western United States, wildfire danger is high and expected to remain so, with the peak of the annual fire season not expected until August. The total number of acres already burned is more than triple the ten-year average. National attention has shifted as one state after another experiences a flare up of forest fires?from California, to Colorado, to Arizona. This Moderate Resolution Imaging Spectroradiometer (MODIS) image from July 15, 2002, places Oregon in the spotlight, with numerous large fires (red dots) scattered throughout the state. The northernmost fire is the Eyerly Fire, which is greater than 17,000 acres and only 40 percent contained. The four large fires dominating the south-central part of the state are the (north-south) Silver, Toolbox, Winter, and Grizzly Complex Fires. The large outline of those fires indicates that MODIS has detected active fire in numerous adjacent 1-km by 1-km pixels, which suggests fires are burning actively on many fronts. Reports from the National Interagency Fire Center state that none of those four fires is more than 5 percent contained. To the south, a large complex of wildfires burning on the California-Nevada border south of Lake Tahoe is proving difficult to contain due to high winds and steep terrain. The Gate Complex Fire is threatening at least 275 structures, and power and water have been lost in some areas as fires burned through power lines. The fire is greater than 10,000 acres and still growing. Please note that the high-resolution scene provided here is 500 meters per pixel.

Winter Storms Lash the Weste …
Title Winter Storms Lash the Western United States
Description Heavy snow covered most of the western United States on January 12, 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. Much of the snow has fallen in a series of storms that started at the end of December. Between December 27 and January 3, 12 to 14 feet (3.7 to 4.3 meters) of snow fell on the Sierra Nevada around Lake Tahoe, and additional snow has fallen since that time. Heavy snow has also fallen on the mountains of Nevada, Utah, and Arizona. As this image shows, the snow is not confined to the mountains. The valleys are also draped in white. Tucked between two mountain ranges, Cache Valley in northern Utah received up to 20 inches (0.51 m) of snow between January 8 and January 12?enough snow to cause trees and power lines to topple and roofs to bow. Not all of the white seen in the true-color image (top) can be attributed to snow. Clouds also cover parts of the region. The false-color image helps distinguish between cloud and snow. Created using visible and infrared wavelengths of energy, the image shows snow and ice as a turquoise blue and warmer water clouds as white. High ice clouds, such as those covering southwestern Colorado, are also turquoise. Vegetation is bright green, and water is dark blue and black. Because water stands out more clearly in the false-color image, floods are also visible. In this image, water has accumulated on the Bonneville Salt Flats west of the Great Salt Lake in northern Utah. Formerly part of a massive lake bed, the Salt Flats consist of a broad, flat plain that is crusted with a deposit of salty minerals and devoid of vegetation. Winter precipitation typically covers the plain with a light layer of water that evaporates in the spring and summer. The ground is bare in the southwest, where the precipitation has fallen as rain. Devastating floods have raged along the rivers of southwestern Utah, northwestern Arizona, and southeastern Nevada, destroying bridges, roads, and homes. In southern California, the rain has triggered widespread floods and a deadly mudslide. Destructive though the floods may be, they are not clearly visible in this image. Despite the problems the storms have caused, the snowfall is a boon to the parched west, where a prolonged drought has drained reservoirs over the past four years. In the western United States, as in many semi-arid regions, the water supply depends on snow melt flowing down from the mountains during the summer. Currently, the snowpack water content (the amount of water stored in mountain snow) is 150 percent of normal in much of the Southwest, reports a scientist from the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center. [ http://www.noaanews.noaa.gov/stories2005/s2364.htm ], The snow could start to relieve the drought as long as a warm spring does not melt the snow too early.

As Earth [ http://antwrp.gsfc.nasa.gov/apod/ap010204.html ] and Mars [ http://antwrp.gsfc.nasa.gov/apod/ap030728.html ] near their closest approach in nearly 60,000 years [ http://mars.jpl.nasa.gov/spotlight/marsClose01.html ] on August 27, the red planet [ http://www.nineplanets.org/mars.html ] has begun to appear dramatically bright and show interesting details [ http://antwrp.gsfc.nasa.gov/apod/ap030724.html ] through telescopes and binoculars. Although not yet visible at sunset, Mars [ http://www.tnni.net/~dustymars/2003_MARS.htm ] can be seen rising [ http://skyandtelescope.com/observing/ataglance/article_110_1.asp ] increasingly earlier in the evening. Once above the horizon, Mars is easy to spot [ http://skyandtelescope.com/observing/objects/planets/article_985_1.asp ], as it sports a distinct orange-red hue and it is the brightest object in the sky after the Sun [ http://antwrp.gsfc.nasa.gov/apod/sun.html ], the nearby Moon [ http://antwrp.gsfc.nasa.gov/apod/moon.html ], and Venus [ http://antwrp.gsfc.nasa.gov/apod/venus.html ]. After Earth overtakes Mars [ http://www.earthsky.com/2003/es030728.html ] in their respective solar orbits, Mars will be visible [ http://www.space.com/spacewatch/mars_preview_021108.html ] right from sunset, although its historic brightness will then begin to fade [ http://www.lpl.arizona.edu/~rhill/alpo/marstuff/ephems/ephem2003.html ]. Pictured above [ http://www.astropics.com/mars/index.htm ], Mars was captured rising in the south east next to Poodle Rock in Valley of Fire State Park [ http://parks.nv.gov/vf.htm ], Nevada [ http://quickfacts.census.gov/qfd/index.html ], USA [ http://www.cia.gov/cia/publications/factbook/geos/us.html ].

Title Alluvial Fans in Mojave Crater: Did It Rain on Mars?
Original Caption Released with Image Click on image for larger version This HiRISE image at up to 29 cm/pixel scale supports the alluvial fan interpretation, in particular by showing that the sizes of the largest rocks decrease away from the mouths of the fans. Aptly-named Mojave crater in the Xanthe Terra region has alluvial fans that look remarkably similar to landforms in the Mojave Desert of southeastern California and portions of Nevada and Arizona. Alluvial fans are fan-shaped deposits of water-transported material (alluvium). They typically form at the base of hills or mountains where there is a marked break, or flattening of slope. They typically deposit big rocks near their mouths (close to the mountains) and smaller rocks at greater distances. Alluvial fans form as a result of heavy desert downpours, typically thundershowers. Because deserts are poorly vegetated, heavy and short-lived downpours create a great deal of erosion and nearby deposition. There are fans inside and around the outsides of Mojave crater on Mars that perfectly match the morphology of alluvial fans on Earth, with the exception of a few small impact craters dotting this Martian landscape. Channels begin at the apex of topographic ridges, consistent with precipitation as the source of water, rather than groundwater. This remarkable landscape was first discovered from Mars Orbital Camera images. Mars researchers have suggested that impact-induced atmospheric precipitation may have created these unique landscapes. Image PSP_001415_1875 [ http://hiroc.lpl.arizona.edu/images/PSP/PSP_001415_1875/ ] was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on November 14, 2006. The complete image is centered at 7.6 degrees latitude, 327.4 degrees East longitude. The range to the target site was 273.5 km (170.9 miles). At this distance the image scale ranges from 27.4 cm/pixel (with 1 x 1 binning) to 109.4 cm/pixel (with 4 x 4 binning). The image shown here has been map-projected to 25 cm/pixel and north is up. The image was taken at a local Mars time of 3:29 PM and the scene is illuminated from the west with a solar incidence angle of 52 degrees, thus the sun was about 38 degrees above the horizon. At a solar longitude of 135.4 degrees, the season on Mars is Northern Summer. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, is the prime contractor for the project and built the spacecraft. The High Resolution Imaging Science Experiment is operated by the University of Arizona, Tucson, and the instrument was built by Ball Aerospace and Technology Corp., Boulder, Colo.

Title Western United States and Southwestern Canada
Original Caption Released with Image This natural-color image from the Multi-angle Imaging SpectroRadiometer (MISR) captures the beauty of the western United States and Canada. Data from 45 swaths from MISR's vertical-viewing (nadir) camera were combined to create this cloud-free mosaic. The image extends from 48° N 128° W in the northwest, to 32°N, 104° W in the southeast, and has been draped over a shaded relief Digital Terrain Elevation Model from the United States Geological Survey. The image area includes much of British Columbia, Alberta and Saskatchewan in the north, and extends southward to California, Arizona and New Mexico. The snow-capped Rocky Mountains are a prominent feature extending through British Columbia, Montana, Wyoming, Colorado and New Mexico. Many major rivers originate in the Columbia Plateau region of Washington, Oregon and Idaho. The Colorado Plateau region is characterized by the vibrant red-colored rocks of the Painted Desert in Utah and Arizona, and in New Mexico, White Sands National Park is the large white feature in the Southeast corner of the image with the Malpais lava flow just to its North. The southwest is dominated by the Mojave Desert of California and Nevada, California's San Joaquin Valley, the Los Angeles basin and the Pacific Ocean. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously from pole to pole, and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. This data product was generated from a portion of the imagery acquired during 2000-2002. The panels utilize data from blocks 45 to 65 within World Reference System-2 paths 31 to 53. 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.
