Improved Data Anlaysis Methods and Impact Studies for Satellite Surface Winds in the Labrador Sea.

摘要

LONG TERM GOAL. The goal of this project is to improve surface wind analyses over the high latitude oceans. OBJECTIVES. The specific objectives are to: (1) develop improved methodologies for the utilization of satellite data in four-dimensional data assimilation and in forecasting, (2) conduct data assimilation experiments in support of the Labrador Sea Experiment, and (3) conduct Observing System Simulation Experiments (OSSE's) to evaluate the potential for advanced passive microwave radiometer to improve ocean surface wind analysis. APPROACH. The approach is to develop a high resolution variational analysis capable of assimilating different types of satellite surface wind data; produce analyses for the Labrador Sea with and without the satellite data, and then evaluate the data impact.
