GHRSST Level 3C Atlantic sub-skin Sea Surface Temperature from the Spinning Enhanced Visible and Infrared Imager (SEVIRI) on MSG at 0 degree longitude (GDS V2) produced by OSI SAF

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.
