Abstract:
Numerous improvements have been made to WindSat ground data processing software and retrieval algorithms since the initial evaluations of WindSat capabilities were published in 2006. These improvements include higher resolution retrievals, improved wind vector ambiguity selection, improved instrument characterization, better brightness temperature calibration and improved high wind speed retrievals. We briefly describe some of these improvements and provide statistical comparisons of the current WindSat ocean vector wind products to the older versions of the WindSat products. We also present comparisons for individual wind fields including examples of gap wind events and cyclonic storms. Limitations of the WindSat products and the underlying causes such as resolution and rain effects will be discussed.
