The Joint NASA-Japanese Global Precipitation Measurement (GPM) Core Observatory (GPM-CO) spacecraft is an advanced successor to the Tropical Rainfall Measuring Mission (TRMM, 1998-2015), with additional channels on both the dual-frequency precipitation radar (DPR) and on the GPM Microwave Imager (GMI) with capabilities specifically designed to sense falling snow along with light, moderate, and heavy precipitation rates. GPM was launched February 2014 and provides data in near-real-time for application and operational users and later for detailed science investigations. More information can be found at: gpm.nasa.gov
