Global Precipitation Measurement Constellation

Submitted by JacobAdmin on

Nine U.S. and international satellites will soon be united by the Global Precipitation Measurement (GPM) mission, a partnership co-led by NASA and the Japan Aerospace Exploration Agency (JAXA). NASA and JAXA will provide the GPM Core satellite to serve as a reference for precipitation measurements made by this constellation of satellites, which will be combined into a single global dataset continually refreshed every three hours.
 

Late Season Tropical Storm Kuena Forms

A tropical storm called Kuena formed in the southwest Indian Ocean east of Madagascar on June 6, 2012. This is a little unusual because the tropical cyclone season in that area normally ends on May 15. The TRMM satellite had an excellent view of Kuena when it flew directly above the newly formed storm on June 6, 2012 at 1607 UTC. A rainfall analysis that used data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS) instrument. This analysis shows that heavy convective storms

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
