SeaWinds L2 25 km winds data record, release 2
Development Climate productReprocessed SeaWinds L2 25 km and 50 km winds Climate Data Records (CDR) have been created covering the full mission history from July 1999 until November 2009. Scatterometer data have been collocated with ECMWF ERA-5 winds and scatterometer level 2 wind products have been created at 25-km and 50-km swath grids.
Identification
OSI SAF producer : Royal Netherlands Meteorological Institute
Identifier : OSI-151-c
Digital object identifier (DOI) 10.15770/EUM_SAF_OSI_0016
Acronym for EDC (APNM) : OR2SWW025
Characteristics
Processing level : L2
Satellite input : QuikSCAT/SeaWinds L2A from PO.DAAC
Other input : ECMWF ERA5 re-analysis outputs (wind, SST, land-sea mask)
Temporal sampling : Once
Timeliness :
?
The timeliness is the time elapsing from the sensing time of the last contributing file to the product dissemination to users. It is similar to the latency.
