After a two-week period without any named storms, the 2011 Atlantic hurricane season revived in late October with the arrival of Hurricane Rina. The storm, which began as a tropical depression on October 23 in the western Caribbean, is adding misery and destruction to a region that has been battered by heavy rain and flooding events.
NASA's Tropical Rainfall Measuring Mission satellite called "TRMM" and NASA's Aqua satellite captured radar and temperaturedata that showed Tropical Storm Rina forming in the western Caribbean Sea yesterday.
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
