SST Match to Data Base

The accuracy of the Atlantic SST fields has been routinely checked at the hourly level against drifting buoy measurements for more than one year. A Match up database (MDB) has been built from in situ data collected daily through the GTS. The corresponding satellite data have been collected in 5*5 pixel boxes (IR resolution) providing the cloud coverage of the box is below 60%. The matchup time window is 1/2 hour. Cloud free cases correspond to a cloud average of the validation boxes below 10%. The maximum admitted value of the satellite zenith angle is 75 degrees. The bias is the mean satellite estimate - buoy SST difference.

Results

The last 12 month validation results are available under a graphic form or as text files.
Select below your satellite and day/night configuration (solar zenith angle lower or larger than 90 deg.)
The broad (limited) validation data set correspond to validation box cloud covers below 60 % (resp. 10%).
