Satellite-measured winds, verified with 15 U.S. west coast buoys, were within 1.3 m s-1 and 26ﾰ RMS. Upwelling estimates derived from geostrophic winds using the Pacific Fisheries Environmental Laboratory (PFEL) technique were compared to those derived from both satellite-measured winds and modelderived winds. Upwelling estimates from model-derived winds agreed with satellite-based estimates at all 14 North American sites and 9 of 11 South American sites. Estimates from geostrophic winds agreed with satellite-based estimates at 12 of 14 North American sites and 7 of 11 South American sites. These comparisons showed that upwelling estimates based on the Navy's global model winds were accurate in more regions than those based on geostrophic winds. A fine-scale upwelling investigation using the Navy's high-resolution atmospheric model (COAMPS) revealed narrow near-shore bands of strong wind-stress and wind-stress-curl missed in the above upwelling estimates.
