GRIDDED SURFACE WIND-STRESS PRODUCT OVER THE WORLD OCEAN CONSTRUCTED BY SATELLITE SCATTEROMETER DATA AND ITS COMPARISON WITH NWP PRODUCTS
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, respec...
