GHRSST Level 3C North Atlantic Regional (NAR) subskin Sea Surface Temperature from Metop/AVHRR (GDS V2) produced by OSI SAF

Published by NASA/JPL/PODAAC;EUMETSAT/OSISAF | National Aeronautics and Space Administration | Metadata Last Checked: February 21, 2026 | Last Modified: 2026-02-17
A Group for High Resolution Sea Surface Temperature (GHRSST) dataset for the North Atlantic Region (NAR) derived from the Advanced Very High Resolution Radiometer (AVHRR) on the European Meteorological Operational-B (MetOp-B) platform (launched 17 Sep 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 realtime from Metop/AVHRR and SNPP/VIIRS. Global AVHRR level 1b data are acquired at Meteo-France/Centre de Meteorologie Spatiale (CMS) through the EUMETSAT/EUMETCAST system.NAR SNPP/VIIRS level 0 data are acquired through direct readout and converted into l1b at CMS.SST is retrieved from the AVHRR and VIIRS infrared channels using a multispectral algorithm.This product is delivered as four six hourly collated files per day on a regular 2km grid. Theproduct format is compliant with the GHRSST Data Specification (GDS) version 2.
