    • Wind Diffusivity Current, Metop-A ASCAT, 0.25°, Global, Near Real Time, 2009-present (Monthly), Lon+/-180

    Metadata Updated: June 10, 2023

    NOAA CoastWatch distributes science quality Ekman current (in zonal, meridional, and modulus sets) and Ekman upwelling data. This data begins with wind velocity measurements from the ASCAT instrument onboard EUMETSAT's Metop-A satellite. ASCAT is a microwave scatterometer designed to measure surface winds over the global ocean. NOAA CoastWatch processes wind velocity to wind stress and wind stress curl, and finally to Ekman current and Ekman upwelling. (This is a monthly composite.)
