The lack of adequate tropospheric observations over marine areas adversely affects the forecast skill of numerical weather prediction systems, and can therefore pose a threat to fleet operations. Clearly, space-based remote sensors must be employed to derive high-quality observations to help fill these data voids. In addition, it is important to marry these data with assimilation systems that c...
