A Group for High Resolution Sea Surface Temperature (GHRSST) dataset for the Eastern Atlantic Region from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) on the Meteosat Second Generation (MSG-3) satellites (launched 5 July 2012).

The European Organization for the Exploitation of Meteorological Satellites (EUMETSAT),

Ocean and Sea Ice Satellite Application Facility (OSI SAF) is producing SST products in near real

time from MSG/SEVIRI. SEVIRI level 1.5 data are acquired at Meteo-France/Centre de

Meteorologie Spatiale (CMS) through the EUMETSAT/EUMETCAST system. SST is retrieved

from the SEVIRI infrared channels (10.8 and 12.0 micrometer) using a multispectral algorithm.

Atmospheric profiles of water vapor and temperature from a numerical weather prediction model,

together with a radiatiave transfer model, are used to correct the multispectral algorithm for

regional and seasonal biases due to changing atmospheric conditions. Every 15 minutes slot is

processed at full satellite resolution. The operational products are then produced by remapping

over a 0.05 degree regular grid (60S-60N and 60W-60E) SST fields obtained by aggregating all 15

minute SST data available in one hour time, and the priority being given to the value the closest in

time to the product nominal hour. The product format is compliant with the GHRSST Data

Specification (GDS) version 2.
