Abstract

Atmospheric surface pressure can be remotely sensed from a satellite by an active instrument which measures return echoes from the ocean at frequencies near the 60 GHz oxygen absorption band. We optimize the instrument by selecting its frequencies of operation, transmitter powers and antenna size through a new procedure based on numerical simulation which maximizes the retrieval accuracy. The predicted standard deviation error in the retrieved surface pressure is 1 mb. In addition the measurements can be used to retrieve water vapour, cloud liquid water and sea state, which is related to wind speed. -Authors
