Integrated Precipitation and Hydrology EXperiment The Integrated Precipitation and Hydrology Experiment (IPHEx) is a ground validation field campaign that will take place in the southern Appalachian Mountains in the eastern United States from May 1 to June 15, 2014. IPHEx is co-led by NASA's Global Precipitation Measurement mission, with partners at Duke University and NOAA's Hydrometerological Testbed. The field campaign has two primary goals. The first is to evaluate how well observations from precipitation-monitoring satellites, including the recently launched GPM Core Observatory, match up...

The Global Precipitation Measurement (GPM) Core Observatory, launched on Feb. 27, 2015, from Tanegashima Space Center in Japan, will help advance our understanding of Earth's water and energy cycles, improve the forecasting of extreme events that cause natural disasters, and extend current capabilities of using satellite precipitation information to directly benefit society. The GPM mission will provide unprecedented data on rain and snowfall. The science instruments on the GPM Core Observatory will provide data that will yield the greatest clarity on rain and snow yet gathered from orbiting...

The Global Precipitation Measurement (GPM) Core Observatory, a joint Earth-observing mission between NASA and the Japan Aerospace Exploration Agency (JAXA), thundered into space at 1:37 p.m. EST Thursday, Feb. 27 (3:37 a.m. JST Friday, Feb. 28) from Japan.

The H-IIA rocket with the Global Precipitation Measurement Core Observatory aboard rolled out to Launch Pad 1 at 1:04 p.m. on Feb. 27 (Japan time) at Tanegashima Space Center, Japan. The rocket is scheduled to lift off during a launch window that opens at 3:37 a.m. (JST) on Feb. 28. (1:37 p.m. Feb. 27 EST).

Global Precipitation Measurement is a big mission. You've got questions? We've got answers. Three days before launch of the Global Precipitation Measurement (GPM) Core Observatory from Tanegashima Space Center in Japan, NASA staff supporting the mission set up shop in the lobby of the Sun Pearl Hotel in nearby Minamitane for a live Twitter Q-and-A to answer questions about the mission and what it will do in orbit. GPM Project Manager Art Azarbarzin and supporting staff Ellen Gray and Rani Gran taking part in the GPM Twitter Q-and-A from the Sun Pearl Hotel on Feb. 25. They were also joined by...
