CIRES Scientist III
Global Systems Division
Dr. Georg Grell leads the development of the online WRF-chemistry model. The Weather Research and Forecast (WRF) model is a next generation Numerical Weather Prediction (NWP) model. Grell collaborates with scientists from many other NOAA laboratories, as well as other national and international institutes and universities on further development of WRF/Chem. Grell also is developing a new approach to parameterize convection using ensemble and data assimilation techniques, and is supervising the effort to develop chemical data assimilation 3DVAR methods for use in real-time air quality forecasting.
