OceanSat-3 50 km wind vectors

Development Near real time product

Near-real time level 2 ocean wind vectors on a 50 km swath grid, based on the backscatter measurements of the Indian Space Research Organisation (ISRO) OceanSat-3/OSCAT-3 scatterometer.

OSI SAF producer : Royal Netherlands Meteorological Institute
Identifier : OSI-113-b
Processing level : L2
Satellite input : OceanSat-3/ OSCAT-3
Other input : NWP outputs (wind, SST, land-sea mask)
