JAXA's Dual-Frequency Precipitation Radar Arrives at Goddard
Released on March 19, 2012
The Dual-frequency Precipitation Radar (DPR) built by the Japan Aerospace Exploration Agency (JAXA) for the Global Precipitation Measurement (GPM) mission's Core Observatory arrived on Friday, March 16 and was unloaded today at NASA's Goddard Space Flight Center, Greenbelt, Md. Comprised of two radars, the DPR is one of two instruments that will fly on the Core Observatory scheduled for launch in February 2014. The GPM mission will provide a new generation of satellite observations of rain and snow worldwide every three hours for scientific research and societal benefits. NASA's mission partner JAXA developed the DPR in cooperation with Japan's National Institute of Information and Communications Technology. The instrument will provide 3-D measurements of the shapes and sizes of raindrops and snowflakes and other physical characteristics that will allow scientists to better understand the physical properties of storms.
GPM Project Manager Art Azarbarzin and Deputy Project Manager Candace Carlisle discuss the Dual-Frequency Precipitation Radar (DPR) as it arrives from Japan and prepares for testing and integration at Goddard.
