They are estimated from near real time satellite observations (QuikScat scatteromter and SSM/I radiometers) and ECMWF operational wind analysis. The spatial and temporal resolutions are 0.25x0.25 degrees in longitude and latitude, and 6 hours.
The blended products are available at synoptic time 00h:00; 06h:00; 12h:00; 18h:00 with a short delay from the real time (24 hours in a nominal mode).
This product is processed at the IFREMER CERSAT data center within the Mersea project.

Description of observation methods/instruments: is given in a pdf file

Quality / Accuracy / Calibration information: is given in a pdf file

Suitability, Expected type of users / uses: for circulation models, oceanography, interaction ocean-atmosphere, climate
