Performance Evaluation of GPS-based Ocean Surface Wind Retrievals
Abstract
Since 1997, researchers at NASA Langley Research Center have been conducting flight tests with a Delay Mapping Receiver (DMR). The data from these flights are archived at the University of Colorado along with concurrent measurements from ERS, TOPEX, QuikSCAT, and buoys. Ocean model estimates are also used for comparison. Improved techniques for GPS-based wind retrieval are applied to all of the valid data in the archive. We will present an analysis of the accuracy of the GPS method for this extensive archive. In particular we categorize the performance based on the reliability of the reference data and the proximity of the reference measurement to the GPS-based measurement in both time and spatial separation. This comprehensive analysis will help to quantify the performance that can be achieved using the DMR for ocean surface wind sensing.
