Abstract

The Tropical Rainfall Measuring Mission (TRMM) has demonstrated the importance of rain measurements for both the science and the meteorological communities. The National Aeronautics and Space Administration (NASA) has established a Pre-Formulation Office to initiate the planning for Global Precipitation Measurement (GPM), a follow-on to TRMM. GPM is envisioned as a multi-satellite constellation using passive and active microwave sensors to take rainfall measurements every few hours on a global basis. This paper discusses the programmatic status of GPM, and opportunities for international partnership arrangements. In addition, the top-level science requirements as currently identified, and concepts under consideration for obtaining the desired measurements, are briefly discussed. Finally, ground data processing and distribution, and an overview of instrument concepts is addressed
