Updated GPM Radiometer Products JacobAdmin Fri, 12/05/2014
The Precipitation Processing System (PPS) has begun producing updated GPM radiometer products as of 12/4/2014 due to an error discovered in the calculation of the Sun Angle in the PPS Geolocation Toolkit. This is considered a minor update with the Product Version being incremented in letter only. Please see the list of affected products here: http://pps.gsfc.nasa.gov/Documents/GPM_PPS_SunAngle_Products_20141204.p… For most radiometers the sun angle is used as ancillary information, but for the TRMM microwave imager (TMI) the correction also slightly impacts brightness temperature and

GPM Measures Rainfall In Tropical Storm Adjali

Moderate rainfall was occurring around the center of Tropical Storm Adjali before it dissipated, according to data from NASA and the Japan Aerospace Exploration Agency's Global Precipitation Measurement or GPM satellites. Adjali became the first named storm of the Southwest Indian Ocean 2014/2015 cyclone season when it formed on November 16, 2014. Adjali became a strong tropical storm the next day and just two days later started to dissipate. The GPM observatory captured data on Adjali's rainfall rates on Nov. 18. GPM's Microwave Imager (GMI) instrument is similar to the Tropical Rainfall
GPM Data Goes Public JacobAdmin Wed, 10/08/2014
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. The GPM Core Observatory, launched from Japan on Feb. 27, carries two advanced instruments to measure rainfall, snowfall, ice

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). Extra-tropical cyclones this strong or stronger are a regular feature of northern European winters. The particularly damaging ones are called "windstorms." Borrowing a page from hurricane forecasters, some weather agencies in affected countries name...

Level 2 GPM Microwave Imager (GMI) Data Released JacobAdmin Mon, 08/04/2014
The Global Precipitation Measurement (GPM) mission's Precipitation Processing System at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has released the Level 2 GPM Microwave Imager (GMI) data to the public. The data set includes precipitation rates, which show how much rain and snowfall accumulate over a given time period. This Level 2 data set of falling rain and snow is computed from Level 1 brightness temperature observations from GMI, the basic measurement made by the instrument of naturally occurring energy radiated, in this case, by precipitation particles (raindrops or

Arthur is the first tropical cyclone of the 2014 Atlantic hurricane season. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency. The Core Observatory was launched Feb. 27 from Japan and began its prime mission on May 29, just in time...
