The postdoctoral fellow will focus their research interests to broadly cover the use of satellite data to provide observational constraints on general circulation and chemical transport models through the use of optimal state estimation (data assimilation) techniques. Interesting aspects of this problem include the application of these techniques to understanding processes controlling ozone and their impact on air quality and climate, providing “top-down” constraints on carbon dioxide fluxes, and creating a framework to reduce uncertainty in the climate response to anthropogenic forcing. At JPL, 4D variational assimilation based on the adjoint of GEOS-Chem has been used. Other approaches, including ensemble Kalman filtering techniques, could also be used.
