A prognostic scheme of sea surface skin temperature for modeling and data assimilation

A prognostic scheme is derived for the computation of sea surface skin temperature in weather forecasting, four-dimensional data assimilation, and ocean- atmosphere coupled modeling. This scheme is then tested using the in situ data over tropical and midlatitude oceans. By implementing this scheme into the ECMWF model, the diurnal variation of sea surface temperature as measured by the geostationary satellite can also be reproduced.
