NASA's latest Earth-observing satellite, the NPOESS Preparatory Project (NPP), is scheduled to launch from Vandenberg Air Force Base on Oct. 28 to extend key environmental data records established by an earlier generation of NASA satellites. To mark the launch, they are looking back at one of the scientific legacies NPP will build upon: the global fire data record.
During the first two weeks of September, and the peak of the Atlantic Hurricane season, NASA satellites were keeping tabs on a number of tropical systems. NASA’s Aqua, Terra, EO-1 and Tropical Rainfall Measuring Mission (TRMM) satellites provided rainfall rates, cloud height, cloud temperature, sea surface temperatures, and extent of cloud cover throughout the life of all the tropical cyclones.
Within the framework of the international Committee on SatelliteEarth Observation (CEOS), the Canadian Space Agency (CSA) is collaborating with NASA on various projects helping to monitor, manage and respond to natural disasters.
A workshop has brought together leading representatives from space agencies and international experts to discuss key issues related to global response and cooperation in the event of a Near Earth Object (NEO) impact threat to Earth.
Flooding along the Missouri River continues as shown in recent Landsat satellite images of the Nebraska and Iowa border. Heavy rains and snowmelt have caused the river to remain above flood stage for an extended period.
A Landsat 5 image of the area from May 5, 2011 shows normal flow. In contrast, a Landsat 7 image from July 17 depicts flood conditions in the same location.
Researchers have devised a model to anticipate drought and forest fires in the Amazon rainforest.The research, which used precipitation records dating back to 1970 and hotspots tracked by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA satellites, finds a strong correlation between sea surf
Ordinarily, the flashes of white in South America’s Atacama Desert rise from salt pans.But on July 7, 2011, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired these images, the white came from a far rarer commodity: snow.
Landsat 5 captured an image of flooding occurring along the Iowa/Nebraska border on June 30, 2011. Flooding is still occurring on July 6, and Flood Warnings are still in effect from the National Weather Service.
The Landsat 5 image captured was an enlargement of the area just north of Omaha. The flood waters show up as very dark blue and, where the water is shallow, medium blue. In the image, the Interstate is cut off by flood waters, just south of Missouri Valley, Iowa, and about 20 miles north of Omaha.
