  • Engineers working on the GPM Core Observatory
    NASA's GPM Core Observatory satellite went through its first complete comprehensive performance test (CPT), beginning on Oct. 4, 2012 at NASA's Goddard Space Flight Center in Greenbelt, Md. The testing ran twenty-four hours, seven days a week and lasted ten days as the entire spacecraft was put through its paces. 
  • Shelf cloud approaching the beach.
    Thank you to everyone who submitted photos to the first installment of our GPM Extreme Weather Photo Competition. We loved all of your entries and thoroughly appreciate your participation! The GPM Photo Competition Committee is happy to announce our top 5 picks. We’ll be sending the submitters NASA bags and GPM stickers. Please stay tuned for additional contests and activities.
  • Map of tracking hurricane Irene
    On August 28, 2011, Tropical Storm Irene hit Vermont, causing widespread damage and the worst flooding in 75 years. Irene's impact in New England shows that tropical cyclones can greatly affect regions outside the view of TRMM. The Global Precipitation Measurement (GPM) mission will build upon TRMM's legacy by examining a larger swath of Earth with more sensitive instruments. 
  • NASA engineer working on GPM
    The electrical integration of the GPM Microwave Imager (GMI) instrument onto the GPM Core Observatory was successfully completed in April 2012. In May, 2012, the Dual-frequency Precipitation Radar (DPR) instrument electrical integration was also successfully completed.
  • The NPOL radar and a Summer Tanger
    NASA and The Nature Conservancy have joined forces to support the ability to measure precipitation on a global scale while also understanding migratory bird habitats on the Eastern Shore of Virginia. The organizations have signed a Space Act Agreement that will provide a location to support NASA’s Precipitation Science programs, in particular the NASA-JAXA Global Precipitation Measurement mission. As a byproduct of this research, data also will be collected that can be used by Nature Conservancy-affiliated researchers to study migratory birds on Virginia’s Eastern Shore.  
  • Water droplets
    In this promotional video NASA scientists discuss why it is so important to study and track Earth's freshwater resources, and explain the purpose of the Global Precipitation Measurement mission. 
  • A misty mountaintop in The Smoky Mountains
    Understanding precipitation in the mountains is one of the first steps to understanding local ecology, regional climate, and the effects of any changes that might impact the nearly 30 million people in Georgia, South and North Carolina, and Tennessee whose water supply comes from southern Appalachian headwaters. To answer some of these big questions, scientists are increasingly turning to satellite data.
  • NASA and JAXA officials at the DPR signing event
    On March 30, the Japan Aerospace Exploration Agency (JAXA) officially handed off a new satellite instrument to NASA at Goddard Space Flight Center, Greenbelt, Md. The Dual-frequency Precipitation Radar (DPR) was designed and built by JAXA and Japan's National Institute of Information and Communications Technology (NICT).
