Ocean Wind Stress

Wind stress is defined as the tangential (drag) force per unit area exerted on the surface of the ocean by the adjacent layer of moving air. Wind stress is the most important forcing parameter in the upper ocean circulation. OSCAT Daily Wind Stress Composites have been generated using DIVA generated 2-days wind field composites. For wind stress computation, Large and Pond (1981) drag coefficients, modified by Trenberth et al. 1990, are used. These products are available on daily basis from 2010-2013. The output products consist of zonal and meridional wind stress components.

Daily OSCAT Ocean wind stress at 25Km, 50Km grid data from 2010-2014, daily SCATSAT Ocean wind curl at 25Km, 50Km grid data from 2016-18 are hosted on Bhuvan-Ocean Wind Curl .
