IPWG
International Precipitation Working Group
The International Precipitation Working Group (IPWG) was established
as a permanent Working Group of the Coordination Group for Meteorological Satellites
(CGMS) on 20-22 June 2001 in Ft. Collins, CO.
The IPWG is co-sponsored by CGMS and the World Meteorological Organization (WMO)
and focuses the scientific community on operational and research satellite based quantitative
precipitation measurement issues and challenges.
It provides a forum for operational and research users of satellite precipitation measurements to
exchange information on methods for measuring precipitation and the impact of space borne precipitation
measurements in numerical weather and hydrometeorological prediction and climate studies.
The IPWG-GPM Application Training
8 - 15 - 22 September, 2021| The three-part webinar series hosted by IPWG and GPM Applications Program will focus on the use of GPM data products
for applications. Specifically, the participant will learn more about how to access GPM data and will be provided demonstrations on precipitation
data access and analysis using NASA's Giovanni tool and Google Earth Engine.
