GHRSST Level 2P sub-skin Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on Metop satellites (currently Metop-A) (GDS V2) produced by OSI SAF (GDS version 2)

A global 1 km Group for High Resolution Sea Surface Temperature (GHRSST) Level 2P dataset based on multi-channel sea surface temperature (SST) retrievals generated in real-time from the Advanced Very High Resolution Radiometer (AVHRR) on the European Meteorological Operational-A (MetOp-A)satellite (launched 19 Oct 2006).

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 Metop/AVHRR. Global AVHRR level 1b data are acquired at Meteo-France/Centre de

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

from the AVHRR infrared channels (3.7, 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. This product is delivered at

full resolution in satellite projection as metagranule corresponding to 3 minutes of acquisition. The

product format is compliant with the GHRSST Data Specification (GDS) version 2.
