ABSTRACT
This study explores the utilization of Special Sensor Microwave/Imager (SSM/I) data in coastal regions where the measured signal consists of radiation received from both land and water surfaces. The problem of mixed land/water measurements ("footprints") is solved using a high-resolution land-sea mask to infer the fraction of water surface for each measurement. A method to combine high-resolution datasets with SSM/II data is described in section 2 and its error characteristics are investigated. It is then used to derive the fraction of water surface within each SSM/II footprint from a high-resolution land-sea mask. The navigation uncertainty of the SSM/I was identified to be the ...
