Description:Ocean surface wind remote sensing using reflectometry measurements from S-band (2.3 GHz) digital communication satellite transmissions is demonstrat ed in tropical cyclones. Twelve days of airborne data were collected during the 2014 Atlantic hurricane season. An empirical model function, relating the sensed ocean surface mean square slope to wind speed, was first developed by fitting mean square slope estimates to comparison wind speed data from the Stepped Frequency Microwave Radiometeron the same aircraft and wind direction data from the Hurricane Weather Research and Forecasting model. This model function was then applied for wind speed retrievals using an independent set of reflectometry measurements and validated against four data sources: Stepped Frequency MicrowaveRadiometer, the Hurricane Weather Research and Forecasting model, dropsondes, and flight-level winds.
