Long-Term Multifrequency Polarimetric Observations of the Sea Surface Emission
Abstract
The long-term goal of this research is to provide passive microwave observations in conjunction with in-situ ocean surface measurements in order to improve empirical and geophysical models of the effect of the ocean surface wind vector on microwave brightness temperatures. Improvements in these models are expected to increase the accuracy of ocean wind vector retrievals from microwave data collected by spaceborne polarimetric microwave radiometers. Airborne and spaceborne ocean sensors necessarily average over large areas (from hundreds of meters to tens of kilometers in diameter) of the surface. Therefore, these sensors measure the integrated emission from a wide variety of sea states or surface conditions. Near-surface observations from geographically dispersed platforms, accompanied by in-situ data, contribute additional quantitative knowledge of surface and sea state effects, providing information to improve ocean surface emission models.
