Satellite - Model Interaction

Oceanic environmental models have reached a point of sophistication whereby they depict numerous observed hydrographic features. Advances in numerical techniques and computer processing capabilities have helped achieve these goals. However, sparse oceanographic data have historically limited ocean forecast modeling efforts. Recent satellite programs utilizing passive and active microwave instruments (SEASAT-A, Nimbus-G, and GEOS-3) have indicated a potential to produce a quantum leap in satisfying numerical model input parameter requirements. Previous results and the potential of scatterometer, Scanning Multichannel Microwave Radiometer (SMMR) and altimeter derived measurements with regards to ocean models will be reviewed. New efforts directed at sea surface temperature (SST) and conversion to sea surface heights and input to ocean models will also be explored.
