The Data Downpour

  • Released Tuesday, January 28, 2014

In a data-processing room at NASA’s Goddard Space Flight Center in Greenbelt, Md., racks of high-powered computers are getting ready to make a map. It's not the familiar satellite map of farms, forests and cities. Instead, this map will show what's hovering above the ground — snowfall and rainfall. The data will come from the Global Precipitation Measurement mission, an international partnership led by NASA and the Japan Aerospace Exploration Agency. The GPM Core Observatory will launch in early 2014, but the mission goes beyond data gathering data from one satellite. Eleven spacecraft from U.S. agencies and other countries, all carrying similar instruments to measure rainfall, will contribute data to this global rain map. Compiling observations from these eleven sources into one unified global data set is the job of the Precipitation Processing System at Goddard.
