Metop-A ASCAT coastal Winds

IDENTIFICATION
DescriptionThe ASCAT Wind Product contains measurements of the wind direction and wind speed above the sea surface. The measurements are obtained through the processing of scatterometer data originating from the ASCAT instrument on EUMETSAT's Metop-A satellite, as described in the ASCAT Wind Product User Manual.

HISTORY, COMMENTS
  • This product superseded :
  • EO:EUM:DAT:METOP:OAS012 (from 28/02/2011 to 28/04/2015)
  • EO:EUM:DAT:METOP:ASCAT12 (from 31/12/2008 to 28/02/2011)
  • It is recommended that the reprocessed ASCAT winds data records (EO:EUM:DAT:METOP:OSI-150-B, EO:EUM:DAT:METOP:OSI-150-A) are used instead of this archived NRT product.
  • See also OSI-104-b (Metop-B ASCAT 12.5 km Winds)
  • Product upgraded on 2018-09-25: geophysical model function CMOD7 used instead of CMOD5, auxiliary data " stress-equivalent ECMWF winds " instead of "real 10m ECMWF background model winds"
