Description
On SKYLAB, a combination microwave radar-radiometer (S193) made measurements from which the winds near the sea surface could be inferred. The analysis of the measurements showed that the wind speed could be computed from the radar measurements with at least the accuracy of the wind speed that would have been reported by a weather ship at the time and location of the radar measurement. The impact of this remote sensing capability will be realized in 1978 with the launch of SEASAT-A, which will carry operational versions of active and passive microwave sensors that will be able to measure both wind speed and direction. Global over ocean routine vector wind measurements should significantly improve the specification of the surface wind and indirectly the surface pressure over the oceans, determine the intensity and structure of tropical cyclones and contribute to improved accuracy of numerical weather forecasting models applied to both the tropics and extratropical atmosphere.
