Radar altimeter missions require precise estimates of the satellite radial orbit position in order to support measurement of surface heights.
The TOPEX/POSEIDON orbit maintenance strategy was changed following launch to include the effects of observed unmodeled, and hence anomalous, along-track accelerations.
Investigated in this study is the response of a global ocean general circulation model to forcing provided by two wind products: operational analysis from the National Center for Environmental Prediction (NCEP); observations made by the ERS-1 radar scatterometer.
