Abstract :
An algorithm that characterizes the measured brightness temperature components due to the atmosphere for the WindSat instrument is described. This study looks at the attenuation due to clear air and non-precipitating clouds in the frequency range of WindSat. A performance assessment of current radiative transfer models and atmospheric absorption models is preformed using comparisons with SSM/I with near-coincident radiosonde profiles of the atmosphere and buoy observations of the surface wind fields. Results of this effort will be reported.
