OSCAT-2, aboard the SCATSAT-1 mission of the Indian Space Research Organization (ISRO), is an active microwave sensor used to determine ocean surface level wind vectors through estimation of radar backscatter.  The ISRO sensor data are processed by the NOAA OSVW team to estimate wind speed and direction in near real time with global coverage, every 4 hours with a spatial resolution of about 12.5 km.  NOAA CoastWatch maps and distributes the OSVW products.
