Oceansat-2 L2 25 km winds data record, release 2

Released Climate product

The OSCAT scatterometer onboard the Oceansat-2 satellite, launched in September 2009 by the Indian Space Research Organisation (ISRO), provided observations until February 2014. Reprocessed Oceansat-2 L2 25 km and 50 km winds Data Records have been created covering the period from December 2009 until February 2014, using the latest state-of-the-art wind retrieval algorithms. Scatterometer data have been collocated with ECMWF ERA-5 winds.
