The PreScat Regional Wind Product contains measurements of the wind direction and wind speed above the sea surface. The measurements are obtained through the processing of scatterometer data originating from the AMI instrument on ESA's ERS-2 satellite. PreScat is developed under the Ocean and Sea Ice Satellite Application Facility project. A scatterometer is a radar instrument that is sensitive to small waves at the sea surface. These small waves, and therefore the backscattered signal, are related to the wind just above the sea surface.
