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 SeaWinds instrument onboard NASA's QuikSCAT satellite. SeaWinds 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.

The data is the 25 hour running average of the zonal component of ocean surface currents derived from High Frequency Radio-derived measurements. THIS IS AN EXPERIMENTAL PRODUCT: intended strictly for scientific evaluation by professional marine scientists.
