Abstract The scheduled February 1985 launch of a radar altimeter aboard the U.S. Navy satellite Geosat has
motivated an in-depth investigation of wind speed retrieval from satellite altimeters. The accuracy of sea
surface wind speed estimated by the Seasat altimeter is examined by comparison with wind speed
estimated by the Seasat scatterometer. The intercomparison is based on globally distributed spatial and
temporal averages of the estimated wind speed. It is shown that there are systematic differences between
altimeter and scatterometer wind speed estimates. These differences arc traced to errors in the Seasat
altimeter geophysical data record wind speed algorithm. A new algorithm is proposed which yields
consistent estimates from the two satellite sensors. Using this new algorithm, the rms difference between
spatial and temporal averages of the Iwo wind speed estimates is less than 1 m/s, and their correlation is
greater than 0.9.
