About:
Dr. Steven J. Greybush is an Associate Professor in the Department of Meteorology and Atmospheric Science, and a Co-Hire of the Institute for Computational and Data Sciences. His research interests include numerical weather modeling, data assimilation, and planetary atmospheres, specifically weather on Earth and Mars. His research team has produced the Ensemble Mars Atmosphere Reanalysis System (EMARS), the first ensemble reanalysis of the Martian atmosphere, which takes spacecraft observations from the NASA Mars Global Surveyor and Mars Reconnaissance Orbiter and combines them with simulations from a Mars Global Climate Model (MGCM) using ensemble data assimilation to produce hourly weather maps of temperatures, winds, atmospheric pressure, dust, and other variables spanning several Martian years. His group has studied Martian weather systems, dust storms, the water cycle, and atmospheric predictability. He also serves as Associate Director for the Center for Advanced Data Assimilation and Predictability Techniques.
