Abstract

A detailed evaluation of NASA scatterometer (NSCAT) data has recently been performed to determine the error characteristics of this data type and its applicability to ocean surface analysis and numerical weather prediction. The first component of this evaluation consisted of both subjective and objective comparisons of NSCAT winds to ship and buoy observations, Goddard EOS (GEOS) and National Centers for Environmental Prediction (NCEP) wind analyses, European Space Agency European Remote Sensing Satellite wind vectors, and Special Sensor Microwave Imager wind speeds. This was then followed by a series of data assimilation and forecast experiments using the GEOS-1 data assimilation system (DAS), the prototype for the GEOS-2 DAS, and an earlier version of the NCEP DAS, that was operational in 1995. This paper will provide a brief summary of these experiments and a few illustrations of the results obtained.
