Profile

Georg A. Grell


Georg Grell received his Ph.D. as a collaborative dissertation (NCAR and the University of Miami) in 1988. He first worked at NCAR before coming to NOAA - Forecast Systems Laboratory (FSL) in 1992. He spent 4 years (1994 – 1998) in Germany at the University of Munich and at the Fraunhofer Institute in Garmisch-Partenkirchen with a research focus on regional climate applications and air quality forecasting, developing the online MM5-Chemistry model. He rejoined FSL in January of 1999, where he led the development of the Weather Research and Forecast model coupled with Chemistry (WRF-Chem) as well as the development of convective parameterizations. Georg serves on the Scientific Advisory Group on Near-Real-Time applications of the Global Atmospheric Watch (GAW) program of the World Meteorological. Organization (WMO). He leads the WRF-Chem working group (http://wrf-model.org/WG11), is a member of the WRF Research and Applications Board, and served as an invited expert on COST (European Corporation in the field of Scientific and Technical Research) actions. Georg is affiliated with the University of Alaska in Fairbanks, and a member of the scientific steering committee of the Shanghai Typhoon Center. Georg is a Co-Chair of the UFS physics working group and the convective parameterization sub-group.
