Doctor of Philosophy, Physics
Aug 1998, State University of New York, Stony Brook,
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.
