GPM

The 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. 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. 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. The map covers more of the globe than any...

Download this video in HD formats from NASA Goddard's Scientific Visualization Studio The Global Precipitation Measurement (GPM) Core Observatory captured a 3-D image of a winter storm on Feb. 17, 2015, that left 6 to 12 inches of snow over much of Kentucky, southwestern West Virginia and northwestern North Carolina. The shades of blue indicate rates of snowfall, with more intense snowfall shown in darker blue. Intense rainfall is shown in red. The imagery shows great variation in precipitation types over the southeastern United States. Download this video in HD formats from NASA Goddard's...

At 5:05 p.m. EST Monday, Jan. 26, 2015, the Global Precipitation Measurement mission's Core Observatory flew over the Nor'easter that dumped snow on New England. This satellite image shows the rate of rainfall, with low amounts in green and high in red, and snowfall, in blue to purple. The center of the storm, shown in 3-D, was offshore with far reaching bands of snowfall. More intense snow rates are shown in darker blue, which can be seen on the northern edge of the storm. Visible in the 3-D image of the center of the storm are the snowy tops of the clouds in blue and underneath where it...

This spring, students worldwide are invited to grab rain gauges and learn how scientists use ground measurements to validate satellite precipitation data. NASA's Global Precipitation Measurement, or GPM, mission is partnering with the Global Learning and Observations to Benefit the Environment (GLOBE) program to conduct a field campaign where students will measure rain and snow in their hometowns from Feb. 1 through mid-April 2015 and then analyze the data. A webinar for teachers to learn more about the campaign and how to participate is scheduled for Jan. 21, 2015. GLOBE is a worldwide hands...

On December 5, 2014 (1032UTC) the Global Precipitation Measurement (GPM) mission's Core Observatory flew over Typhoon Hagupit as it headed towards the Philippines. A few hours later at 1500 UTC (10 a.m. EST), Super Typhoon Hagupit's maximum sustained winds were near 130 knots (149.6 mph/241 kph), down from 150 knots (172 mph/277.8 kph). Typhoon-force winds extend out 40 nautical miles (46 miles/74 km) from the center, while tropical-storm-force winds extend out to 120 miles (138 miles/222 km).
