Over the past years we have developed methods to estimate surface fluxes of net solar radiation and latent heat using multi-sensor satellite observations. Using a combination of Special Sensor Microwave Imager (SSM/I) products and data from the Comprehensive Ocean-Atmosphere Data Set (COADS), our estimates of surface evaporation cover a total of six-years (1988-1993). The surface net solar radiation is estimated with data from the International Satellite Cloud Climatology Project (ISCCP), and covers the period from July 1983 through June 1991.
Along with satellite estimates of precipitation, we have recently computed global fields of surface freshwater fluxes, as well as global estimates of oceanic freshwater transport. Our current research aims to diagnose interannual variations in surface freshwater fluxes and oceanic transport.
We are particularly interested in using our satellite data in combination with ocean General Circulation Models (GCM's) to study the role that interannual variations in surface freshwater fluxes play in long term variations in the oceanic circulation.
