The Global Precipitation Measurement mission's Core Observatory flew over Hurricane Arthur five times between July 1 and July 6, 2014. Arthur is the first tropical cyclone of the 2014 Atlantic Hurricane season. It formed as a tropical storm on Tuesday, July 1 and reached maximum intensity as a Category 2 hurricane on July 4, disrupting some coastal U.S. Independence Day celebrations. This visualization is taken from the flyover on July 3, 2014 with Hurricane Arthur just off the South Carolina coast.

GPM Data Release Schedule Announced

The GPM Core Observatory satellite was successfully launched on February 27th, 2014. Data from the GPM Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) have the following release schedule. All data are freely available through the NASA's Precipitation Processing System at http://pps.gsfc.nasa.gov June 16th – GMI Level 1 Brightness Temperature data have been released. This includes GMI instrument swath data. July 14th – GMI Level 2 Precipitation Rate data will be released. This includes precipitation rates estimated using the Goddard Profiling algorithm (GPROF14) and are

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...

GPM Launches from Tanegashima Space Center

A Japanese H-IIA rocket with the NASA-Japan Aerospace Exploration Agency (JAXA), Global Precipitation Measurement (GPM) Core Observatory onboard, is seen launching from the Tanegashima Space Center, Friday, Feb. 28, 2014, Tanegashima Space Center. The GPM spacecraft will collect information that unifies data from an international network of existing and future satellites to map global rainfall and snowfall every three hours.

GPM Power Positive

The GPM Core Observatory has successfully deployed its solar arrays and is stable and pointed at the sun. GPM’s solar arrays are pointed at the sun and collecting power. We have confirmation that the arrays are rotating properly, charging the batteries and providing power to the spacecraft.

Solar Array Deployment Begins

Solar array deployment begins. GPM has two arrays to power the spacecraft because of its orbit. It circles the Earth at an angle slanted 65 degrees up from the equator. This means it does not cross the equator at the same time every day – an advantage for monitoring rainfall at different times of day and night.

Second Flight Attitude Control Test Completed

A second scheduled test of the guidance and control system on the H-IIA launch vehicle has been completed to confirm that all devices for flight attitude control are working as expected. NASA Television has begun coverage of the GPM Core Observatory launch originating from Goddard Space Flight Center in Greenbelt, Md. Watch online at: http://www.nasa.gov/nasatv
