[Via Satellite 01-28-2014] NASA’s new Global Precipitation Measurement (GPM) Core Observatory, a joint project with the Japan Aerospace Exploration Agency (JAXA), is scheduled to launch Feb. 27. As the first coordinated international satellite, the GPM will provide near real-time observations on all types of precipitation. Data form the GPM will be used to study climate change, freshwater resources, floods and droughts, and hurricane formation and tracking.

“GPM will provide scientists and forecasters critical information to help us understand and cope with future extreme weather events and fresh water resources,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington.

GPM’s Core Observatory will carry two instruments to measure rain and snowfall: the Dual-frequency Precipitation Radar (DPR) and the GPM Microwave Imager (GMI). These instruments will provide new capabilities for observing smaller particles of rain, ice and snow.
