GPM Core Observatory and Partner Satellites. Scheduled to launch in 2014. Therefore the GPM Core Observatory will carry the first space-borne Ku/Ka-band Dual-frequency Precipitation Radar. Also a multi-channel GPM Microwave Imager (GMI).
It will be supported by a network of partner-provided satellites to provide near-real-time precipitation measurements around the globe. Therefore the GPM mission is a joint effort between NASA. And the Japan Aerospace Exploration Agency. (JAXA) And other international partners. GPM Core Observatory and Partner Satellites also have a ton of tracking.
Therefore the GPM mission will improve climate, weather and hydrological predictions by providing more accurate precipitation measurements from space. Also the first space borne radar at the observatory. The GMI instrument will play an essential role in the worldwide measurement of precipitation and environmental forecasting when GPM launches. The GMI will be extremely beneficial to forecasters during extreme weather events. GMI data will allow scientists to both track tropical cyclones and forecast their progression or detect falling snow from space.
GPM builds on the notable successes of the Tropical Rainfall Measuring Mission (TRMM), which was also a joint NASA-JAXA activity. The project is managed by NASA’s Goddard Space Flight Center, and consists of a GPM Core Observatory satellite assisted by a constellation of spacecraft from other agencies and missions.
