It covers an area 20 by 30 miles (33 by 48 kilometers). From the vantage point of the Terra satellite, the instrument can detect the scarred land that the wildfire, burning north of Tucson, is leaving in its wake. Version 3 also features a new global product: the ASTER Water Body Dataset (ASTWBD). Vegetated areas range in color from red to pink, snow is white, water is black, and bare rock is earth-toned. This perspective image of a complex volcanic landscape in the Andean mountain range was assembled from data acquired by ASTER on April 9, 2003. (EOS) launched in December 1999. Read more on NASA’s Earth Observatory. Dust storms over the Caspian Sea lead to increased evaporation. Regardless, snow levels in the Sierra Nevada mountains were still below average. The first ASTER GDEM was released in 2009, with Version 2 being released in 2011. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging instrument onboard Terra, the flagship satellite of NASA's Earth Observing System (EOS) launched in December 1999. Efforts to contain the fire continue with 21 hand crews, 10 helicopters and dozens of fire engines deployed to the area. Does Dust Affect Water Levels of the Caspian Sea. Learn more about this phenomenon on NASA’s Earth Observatory. Regardless, snow levels in the Sierra Nevada mountains were still below average. ASTER Web Site (Jet Propulsion Laboratory), Satellite Data Meets Cellular DNA for Species of Interest, NASA Observations Aid Efforts to Track California’s Wildfire Smoke From Space, NASA's Terra Highlights Aerosols From Western Fires in Danger Zone. The August Complex Fire and others this fire season have been sending far-reaching plumes of wildfire smoke into the atmosphere that worsen air quality in California and beyond. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite acquired an image of the burn scar on June 19, 2016. As Hawaii’s Kilauea continues to erupt, ASTER continues to monitor the eruption from space. The U.S. science team is located at NASA’s Jet Propulsion Laboratory in Southern California. This is not a typical location dust events such as this one. The Moderate Imaging Spectroradiometer (MODIS) on NASA’s Terra Satellite captured images of a whiting event in Lake Kivu. Vegetated areas range in color from red to pink, snow is white, water is black, and bare rock is earth-toned. Greening Ascension Island – When Charles Darwin first visited Ascension Island it was barren, but with the assistance of Joseph Hooker in the 1800s plants were introduced and now cover much of this once bleak island. The Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites acquired images of the ash plume at 11:45 a.m on March 28, 2016. Satellite Data Meets Cellular DNA for Species of Interest, NASA Observations Aid Efforts to Track California’s Wildfire Smoke From Space, NASA's Terra Highlights Aerosols From Western Fires in Danger Zone, NASA’s ASTER Sees Arizona’s Bighorn Fire Burn Scar From Space. ASTER data are used to create detailed maps of land surface temperature, reflectance,
The Moderate Imaging Spectroradiometer on NASA’s Terra Satellite captured this striking image of the formation of two new icebergs as they broke away from the Nansen Ice Shelf into the Southern Ocean on April 7, 2016. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging
When it erupts lahars, flows of volcanic debris and sediment, can have devastating impacts, prompting geologists to regularly monitor the volcano, using the Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA’s Terra satellite. A Sudden Color Change on Lake Kivu – The Moderate Imaging Spectroradiometer (MODIS) on NASA’s Terra Satellite captured images of a whiting event in Lake Kivu. Extremely dry vegetation and windy conditions caused the fire to spread quickly.
These “streets of the sky” called cloud streets are long parallel bands of cumulus clouds. Images from NASA’s Moderate Imaging Spectroradiometer (MODIS) clearly show the difference between years. NASA’s Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument aboard the Terra satellite imaged some of the burned area on June 29. In a joint announcement by the US and Japan, the entire ASTER archive was opened to the public. and a drop in lake level according to new research using observations of dust collected by instruments on several satellites including the Moderate Imaging Spectroradiometer (MODIS ) and the Multi-angle Imaging Spectroradiometer (MISR) on Terra.
Images from NASA’s Moderate Imaging Spectroradiometer (MODIS) clearly show the difference between years. Antarctic Ice Shelf Sheds Bergs – The Moderate Imaging Spectroradiometer on NASA’s Terra Satellite captured this striking image of the formation of two new icebergs as they broke away from the Nansen Ice Shelf into the Southern Ocean on April 7, 2016. The coordinated system of EOS satellites, including Terra, is a major component
Any scene, and all derived products, can be ordered by anyone. ASTER is uniquely capable of turning to see areas where volcanoes are erupting in very high resolution (between 15 in the thermal bands – 90 meter spatial resolution in the visible light spectral bands).
