Education:

Doctor of Philosophy, Physics

Aug 1998, State University of New York, Stony Brook, NY

Ph. D. Thesis: Estimates of Diabatic Terms in the GEOS-1 DAS: The Roles of Biases

Evaluated the diagnostic diabatic fields in the GEOS-1 DAS by comparing with observations

Identified possible causes for systematic errors in those fields

Isolated the roles of biases of the prognostic fields that caused those errors, by running assimilation experiments.
