Spaceborne Precipitation Radar Ships from Japan to U.S.
By Aries Keck, NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 2/8/12) GREENBELT, Md. – Japanese scientists and engineers have completed construction on a new instrument designed to take 3-D measurements of the shapes, sizes and other physical characteristics of both raindrops and snowflakes. The instrument will be shipped from Japan to NASA's Goddard Space Flight Center, Greenbelt, Md., to be integrated into an upcoming NASA Earth science satellite. Designed and built by the Japan Aerospace Exploration Agency (JAXA) and Japan's National Institute of Information
GPM's Snow Ground Validation Underway
The GPM Cold-season Precipitation Experiment (GCPEx) to measure falling snow is currently underway in Ontario, Canada. The field campaign, which runs from January 17 to February 29, 2012, is designed to improve satellite estimates of falling snow and test ground validation capabilities for GPM.
