Monthly and Climatological Tropical Pacific Wind Stress

Five million international ship observations of the Pacific trade winds are presented in monthly summaries. For each month in the period from 1947 to 1973, a 10-degree latitude by 2-degree longitude grid includes various wind and wind stress information. Coverage within the grid is not 100% as most observations occurred along shipping routes. Most of the raw wind observations were Beaufort estimates that were converted to wind speed and direction.
