Biography

Dr. William Gustafson has wide-ranging experience applying atmospheric models across scales ranging from large-scale Tropical dynamics to urban air quality. His recent work focuses primarily on development and application of the WRF-Chem meteorology and atmospheric chemistry model for studies of aerosols and their impact on climate via interactions with radiation and clouds. He also is active in using mesoscale models to downscale global climate model simulations. Past research includes investigations of the Madden-Julian Oscillation, storm events in the California Central Valley, and flow in complex topography.
