GRIDDED SURFACE WIND-STRESS PRODUCT OVER THE WORLD OCEAN CONSTRUCTED BY SATELLITE SCATTEROMETER DATA AND ITS COMPARISON WITH NWP PRODUCTSDOI: 10.4067/S0717-65382004000300006 Abstract: products of gridded surface wind and wind-stress vectors over the world ocean are constructed by satellite scatterometer (ers-1/2 and qscat/seawinds) data with highly temporal and spatial resolutions. data of the ers-1/2 and the qscat/seawinds cover periods of 1992-2000 and since august 1999, respectively, and permit us to establish a long-term time series. we make validation for our products by inter-comparison with in-situ data (tao and ndbc buoys), and find that our qscat product has high reliability in the almost whole area around buoy locations. for areas where there are no in-situ data such as the high-latitude southern ocean, we also make inter-comparison of our products with numerical weather prediction(nwp) ones (ncep and ecmwf). results reveal that there are significant differences in the westerly region of 40°- 60°s, suggesting that the wind-stress magnitudes calculated from the ncep reanalysis 6-hourly product are overestimated in the high latitudes
