ERS L2 25 km winds data record

Released Climate product

Reprocessed ERS-1 and ERS-2 L2 25 km winds Climate Data Records (CDR) have been created covering the period from March 1992 until January 2001, using the latest state-of-the-art wind retrieval algorithms. Scatterometer data have been collocated with ECMWF ERA-Interim winds and scatterometer level 2 wind products have been created at 25 km swath grid. The reprocessed data are in BUFR and NetCDF format.
