Dr. George J. Huffman is a Research Physical Scientist at NASA Goddard Space Flight Center (GSFC), Greenbelt, Maryland. After completing a B.S. in Physics at The Ohio State University (1976) and a Ph.D. in Meteorology at Massachusetts Institute of Technology (1982), he was an Assistant Professor at University of Maryland, College Park, then moved to GSFC in 1988, where he consulted until entering government service in 2012. Dr. Huffman’s primary focus has been the design, implementation, and extension of combined (satellite-gauge) estimates of global precipitation. The resulting data sets include the Global Precipitation Climatology Project (GPCP) monthly and daily products (carried out as a contribution to the World Climate Research Program, WCRP); the NASA Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis; and the successor NASA Global Precipitation Measurements (GPM) mission’s Integrated Multi-satellitE Retrievals for GPM (IMERG). Allied work includes estimating errors and extreme precipitation event statistics. Dr. Huffman is the Project Scientist for GPM, as well as the lead for the GPM Multi-satellite Algorithm Team. His research has resulted in 145 publications, 15 as first author, and numerous presentations. As well, he is the Chief for the Mesoscale Atmospheric Processes Lab at GSFC. Recent awards include NASA/GSFC Special Act Team Award, Earth Sciences Division Lab Management, 2021; NASA/GSFC Robert H. Goddard Group Award for Science, IMERG Development Team, 2019; Fellow of the American Meteorological Society, 2019; and NASA Exceptional Service Medal, 2018.
A key goal for the Global Precipitation Measurement (GPM) mission is to assemble data from the international constellation of precipitation-relevant satellites, intercalibrate them to the standard provided by the GPM Core Observatory, and combine them in an optimal way that provides stable, global, fine-scale precipitation maps for the entire TRMM-GPM era. The algorithms to do this are considered national (versus "project" for the Core Observatory products). IMERG is the U.S. National product, representing a code-level merger of legacy algorithms from NASA, NOAA, and Univ. of Calif. Irvine. IMERG data fields are computed on a 0.1°x0.1° global grid (although gaps exist at high latitudes at present). The data are computed on 30-minute and monthly intervals. The Early, Late, and Final Runs are computed with latencies of 3 hours, 12 hours, and 3.5 months, with the last including precipitation gauge data. Data start 1 June 2000. The new Version 07 is slated to begin production in August 2022. IMERG datasets are the most-requested datasets in GPM.
The Global Precipitation Climatology Project (GPCP) was established by the Global Energy and Water Experiment (GEWEX; now Global Energy and Water Exchange project) in the early 1990's to provide climate-scale, fully global precipitation products as an international community effort involving data providers and precipitation scientists. The precipitation research group at Goddard has provided detailed product development for GPCP. The legacy Version 2.3 GPCP is computed on a 2.5°x2.5° monthly grid for 1979-present in Version 2.3 and 1°x1° daily grid for October 1996-present. A group at Univ. of Maryland College Park is leading Version 2.3 as a formal Climate Data Record (CDR) in NOAA. Version 3 GPCP datasets (currently in V3.2) provide monthly and daily products on a 0.5°x0.5° grid for 1983-present and June 2000-present, respectively. These are computed at Goddard and archived in the Goddard Earth Sciences Data and Information Services Center (GES DISC). For both collections, the datasets are fully global, emphasize data record homogeneity, and ensure consistency between the monthly and daily products for each version. The GPCP data sets are highly cited in the scientific literature.
Produce, revise, analyze GPCP Satellite-Gauge and One-Degree Daily data sets; develop, revise, analyze TRMM Multi-satellite Precipitation Analysis data sets in real (3B42RT) and post-real (3B42, 3B43) time; leading IMERG, the U.S. GPM Day-1 multi-satellite algorithm; Deputy Project Scientist, then Project Scientist for GPM and Deputy Chief, then Chief for the Mesoscale Atmospheric Processes Lab. Funded on projects as P.I. and Co-I.

Dr. George J. Huffman is a Research Physical Scientist at NASA Goddard Space Flight Center (GSFC), Greenbelt, Maryland. After completing a B.S. in Physics at The Ohio State University (1976) and a Ph.D. in Meteorology at Massachusetts Institute of Technology (1982), he was an Assistant Professor at University of Maryland, College Park, then moved to GSFC in 1988, where he consulted until entering government service in 2012. Dr. Huffman’s primary focus has been the design, implementation, and extension of combined (satellite-gauge) estimates of global precipitation. The resulting data sets include the Global Precipitation Climatology Project (GPCP) monthly and daily products (carried out as a contribution to the World Climate Research Program, WCRP); the NASA Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis; and the successor NASA Global Precipitation Measurements (GPM) mission’s Integrated Multi-satellitE Retrievals for GPM (IMERG). Allied work includes estimating errors and extreme precipitation event statistics. Dr. Huffman is the Project Scientist for GPM, as well as the lead for the GPM Multi-satellite Algorithm Team. His research has resulted in 145 publications, 15 as first author, and numerous presentations. As well, he is the Chief for the Mesoscale Atmospheric Processes Lab at GSFC. Recent awards include NASA/GSFC Special Act Team Award, Earth Sciences Division Lab Management, 2021; NASA/GSFC Robert H. Goddard Group Award for Science, IMERG Development Team, 2019; Fellow of the American Meteorological Society, 2019; and NASA Exceptional Service Medal, 2018.
