The most accurate and comprehensive collection of rain, snowfall and other types of precipitation data ever assembled now is available to the public. This new resource for climate studies, weather forecasting, and other applications is based on observations by the Global Precipitation Measurement (GPM) Core Observatory, a joint mission of NASA and the Japan Aerospace Exploration Agency (JAXA), with contributions from a constellation of international partner satellites.
On September 26, the Global Precipitation Measurement (GPM) satellite flew over an extra-tropical cyclone whose center was approaching Norway. The Norwegian weather service reported that this storm brought gale-force winds to parts of Norway's coast and mountains (20 m/s in the mountains and 50 m/s just off-coast, late at night on September 26).
One of the first storms observed by the NASA/JAXA GPM Core Observatory on March 17, 2014, in the eastern United States revealed a full range of precipitation, from rain to snow.

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 Global Precipitation Measurement mission's Core Observatory is performing normally. On April 2, the GPM Core Observatory fired its thrusters for an 80-second delta-V burn that accelerated the spacecraft and circularized its orbit. The Core Observatory is now flying in its final orbit, 253 miles (407 kilometers) above Earth's surface.
