[ Watch the Video ] 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, we are looking back at one of the scientific legacies NPP will build upon: the global fire data record. An instrument on NPP called the Visible Infrared Imager Radiometer Suite (VIIRS) will extend this...

BU researchers find that modeling errors produced exaggerated claims A new, comprehensive study by an international team of scientists, including scientists at Boston University in the US and the Universities of Viçosa and Campinas in Brazil, has been published in the current issue of Science (August 26, 2011) refuting earlier alarmist claims that drought has induced a decline in global plant productivity during the past decade and posed a threat to global food security....

A new study funded by NASA has found that Amazon forests are losing their greenness due to last year's record-breaking drought. "The greenness levels of Amazonian vegetation -- a measure of its health -- decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," Liang Xu of Boston University and the study's lead author said in a statement. Researchers used computer models...

Recent research surrounding the impact of drought in the Amazon has provided contradictory findings as to how tropical forests react to a drier and warmer climate. A new study published in the August 2 Early Edition of the Proceedings of the National Academy of Sciences (PNAS) examines the response of Amazon forests to variations in climate conditions, specifically considering how those changes may influence forest productivity. These findings provide possible context for why previous studies...

NASA's Terra satellite captured an image of the ash plume from Iceland's Eyjafjallajökull volcano this morning, April 20, as it flew overhead from its vantage point in space. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite captured visible image of the ash plume (consisting of fine particles of pulverized rock) at 11:55 UTC (7:55 a.m. EDT). The plume appeared to be lighter in color than the previous few days, and it was drifting south and...

A national early warning system designed to assist land managers in rapidly detecting threats to forest health is featured in the cover article of the October 2009 issue of Photogrammetric Engineering and Remote Sensing (PE&RS), the journal of the American Society for Photogrammetry and Remote Sensing (ASPRS). The article, entitled "Toward a National Early Warning System for Forest Disturbances Using Remotely Sensed Canopy Phenology," describes the vision and progress of the system in...

About half of the oil in the ocean bubbles up naturally from the seafloor, with Earth giving it up freely like it was of no value. Likewise, NASA satellites collect thousands of images and 1.5 terabytes of data every year, but some of it gets passed over because no one thinks there is a use for it. Scientists recently found black gold bubbling up from an otherwise undistinguished mass of ocean imagery. Chuanmin Hu, an optical oceanographer at the University of South Florida, St. Petersburg,...
