Impact of Assimilating COWVR in the Navy's Global Numerical Model

Abstract

This work assimilates the Compact Ocean Wind Vector Radiometer (COWVR) clear-sky radiances and evaluate their influence on the Navy's global numerical weather prediction system. COWVR assimilation in NAVGEM shows a comparable positive impact on the 24-h model forecasts to that of legacy microwave sensors. Furthermore, the assimilation of COWVR radiances demonstrates a substantial positive impact on wind forecasts beyond the 72-h lead-time, particularly in the Tropics and Southern Hemisphere.
