06.07.12 - Ground radar set up on the Eastern Shore of Virginia to validate satellite rain measurements will do double duty for The Nature Conservancy as a tool to track migratory birds.
04.20.12 - The Southern Appalachians are one of the rainiest places in the United States, and scientists have discovered that much of it is difficult to detect light rain.
04.03.12 - On March 30, the Japan Aerospace Exploration Agency officially handed off a new satellite instrument to NASA.
03.20.12 - The Dual-frequency Precipitation Radararrived on Friday, March 16 and was unloaded today at Goddard.
03.01.12 - The Global Precipitation Measurement Microwave Imager (GMI) instrument has arrived at Goddard for integration into NASA's upcoming Earth science spacecraft.
01.12.12 - NASA's DC-8 research plane will begin six weeks of flights over Canada next week in support of a difficult task of the upcoming Global Precipitation Measurement (GPM) mission -- measuring snowfall from space.
01.09.11 - The GPM Cold-season Precipitation Experiment (GCPEx) will be conducted in cooperation with Environment Canada in Ontario, Canada from January 15th to February 26, 2012.
10.19.11 - In the clean room at NASA Goddard Space Flight Center, the GPM mission's Core satellite is steadily taking shape.
The GPM Core Spacecraft is being developed and tested in-house at NASA Goddard Space Flight Center. At 8,000 pounds and flying 485 miles above the ground, the Core carries the two scientific instruments to make measurements of rainfall on Earth: the GPM Microwave Imager (GMI) and the Dual-frequency Precipitation Radar (DPR).
Constantly scanning the Earth’s surface, the TRMM Microwave Imager (TMI) allows scientists to both track tropical cyclones and forecast their progression.
