Successful Electrical Integration of GPM’s Two Instruments

The electrical integration of the Global Precipitation Measurement Microwave Imager (GMI) instrument onto the GPM Core Observatory was successfully completed in April 2012. Ball Aerospace and Technologies Corp. Boulder, Colo. built the GMI, which arrived at NASA's Goddard Space Flight Center in Greenbelt, Md. in early March and after post shipment processing it was handed over to NASA. The GMI is one of the key instruments for the GPM Core Observatory. This instrument is a passive radiometer with 13 channels covering frequencies from 10 to 183 GHz. In May, 2012, the Dual-frequency

JAXA Launches GCOM-W1 Satellite

Congratulations to our partner, the Japan Aerospace Exploration Agency (JAXA), for the successful launch yesterday of the Global Change Observation Mission 1st - Water (GCOM-W1). GCOM-W1 carries the Advanced Microwave Scanning Radiometer 2 (AMSR2) which successfully deployed its antenna on orbit. AMSR2 will detect microwave radiation to measure sea surface temperature, sea surface wind speed, sea ice concentration, snow depth, soil moisture, water vapor, cloud liquid water, and precipitation. GCOM-W1 will be a part of the GPM constellation, contributing its measurements to the GPM global data

Handover of Japan-built Radar to NASA

By Ellen Gray, NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 4/3/12) On March 30, the Japan Aerospace Exploration Agency (JAXA) officially handed off a new satellite instrument to NASA at Goddard Space Flight Center, Greenbelt, Md. The Dual-frequency Precipitation Radar (DPR) was designed and built by JAXA and Japan's National Institute of Information and Communications Technology (NTSpace).

Light Rain in The Smoky Mountains

A misty mountaintop in The Smoky Mountains
Tuesday, April 24, 2012
By Lisa-Natalie Anjozian , NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 4/24/12) If you walk into a cloud at the top of a mountain with a cup to slake your thirst, it might take a while for your cup to fill. The tiny, barely-there droplets are difficult to see, and for scientists they, along with rain and snow, are among the hardest variables to measure in Earth Science, says Ana Barros, professor of engineering at Duke University. As part of the Science Team for NASA's Precipitation Measurement Missions (PMM) that measure rainfall from space, Barros and her...
