![]() The precipitation data collected covers the 87 percent of the globe that falls between 60 degrees north and 60 degrees south latitude, updated every half hour.The map covers more of the globe than any previous NASA precipitation data set, allowing scientists to see how rain and snowstorms move around nearly the entire planet. The result is NASA's Integrated Multi-satellite Retrievals for GPM data product, called IMERG, which combines all of these data from 12 satellites into a single, seamless map.This first IMERG data set spans the initial months of GPM data collection from April to September, 2014. 27, 2014 as a collaboration between NASA and the Japan Aerospace Exploration Agency – acts as the standard to unify precipitation measurements from a network of 12 satellites. Global Precipitation Measurement mission has produced its first global map of rainfall and snowfall.Like a lead violin tuning an orchestra, the GPM Core Observatory – launched one year ago on Feb. New NASA Earth Science Mission Expand View of Our Home Planet. NASA Releases First Global Rainfall and Snowfall Map from New Mission. Matthew McGill, Cloud Aerosol Transport System (CATS) principal investigator, NASA’s Goddard Space Flight Center Ralph Basilio, Orbiting Carbon Observatory-2 project manager, NASA’s Jet Propulsion Laboratory, Pasadena, Californiaīryan Stiles, ISS-RapidScat science processing lead, NASA’s Jet Propulsion Laboratory Gail Skofronick-Jackson, GPM project scientist, NASA’s Goddard Space Flight Center, Greenbelt, Maryland Peg Luce, deputy director of the Earth Science Division in NASA’s Science Mission Directorate, Headquarters, Washington New views of global carbon dioxide, rain and snowfall, ocean winds, and aerosol particles in the atmosphere will be presented during the briefing. NASA scientists will discuss early observations from the new missions and their current status during a media teleconference at 2 p.m. Over the past 12 months NASA has added five missions to its orbiting Earth-observing fleet – the biggest one-year increase in more than a decade.
