Abstract

In this work, we examine the relevance of an improved model for the microwave brightness temperature over calm ocean to the TOPEX/Poseidon satellite. The model is divided into two sub-models, the atmospheric absorption model and the ocean surface emissivity model. Both models are developed from a comparison via Newthon-Raphson iterative method of ancillary data as required by the radiative transfer equation, with well calibrated radiometer data. Finally, the contribution of both models to the overall error budget for the wet troposphere propagation path delay estimation algorithm is presented. The path delay is used to correct the altimeter sensor on board of the satellite utilized to measure global sea surface topography. The improvement in the accuracy of the path delay is found to be 37% which render more accurate measurements from this satellite mission.
