An old adage about environmental stewardship goes, “Think Globally, Act Locally.” When it came to rainfall, however, Arthur Hou, project scientist for the Global Precipitation Measurement mission from 2005 until his passing on November 20, 2013, took an approach of Think Globally, Act Globally.

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.
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.

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.
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.
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. 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.

The green light has been given to the X-60 minutes countdown operation for launch of the NASA-JAXA GPM Core Observatory from Tanegashima Space Center, Japan.
Launch is scheduled for 3:37 a.m. JST (Feb. 27 at 1:37 p.m. EST).
