The satellite input data has successively come from Metop-A, Metop-B and Metop-C level 1 data processed at EUMETSAT. SST is retrieved from AVHRR infrared channels (3.7, 10.8 and 12.0 µm) using a multispectral algorithm and a cloud mask. Atmospheric profiles of water vapor and temperature from a numerical weather prediction model, Sea Surface Temperature from an analysis, together with a radiative transfer model, are used to correct the multispectral algorithm for regional and seasonal biases due to changing atmospheric conditions. The quality of the products is monitored regularly by daily comparison of the satellite estimates against buoy measurements.The product format is compliant with the GHRSST Data Specification (GDS) version 2. Users are advised to use data only with quality levels 3,4 and 5. onGoing Stéphane Saux Picart Météo-France stephane.sauxpicart@meteo.fr author OSI SAF Help Desk osi-saf.helpdesk@meteo.fr pointOfContact Ifremer/CERSAT > Centre de Recherche et d'Exploitation Satellitaire, Institut Français de Recherche et d'Exploitation de la Mer cersat@ifremer.fr distributor EUMETSAT ops@eumetsat.int distributor NASA/JPL/PODAAC > Physical Oceanography Distributed Active Archive Center, Jet Propulsion Laboratory, NASA podaac@podaac.jpl.nasa.gov distributor Météo-France osi-saf.ops@meteo.fr originator EUMETSAT osi-saf.manager@meteo.fr funder Météo-France osi-saf.manager@meteo.fr funder https://sextant.ifremer.fr/geonetwork/srv/api/records/cac10327-d8c6-4b34-91b9-11306a7c3ddb/attachments/Metop_1_Granule_Gibraltar_14052023_1granule_3.jpg Example of Metop L2P Full resolution Sea Surface Temperature metagranule CERSAT Remote sensing Oceanographic geographical features GEMET - INSPIRE themes, version 1.0 2018-01-01 publication 2018-07-27T14:39:48 publication geonetwork.thesaurus.external.theme.httpinspireeceuropaeutheme-theme Ocean Temperature Cersat - Parameter 2024-07-26 publication 2024-07-26 publication geonetwork.thesaurus.local.theme.cersat_parameter OSI SAF GHRSST Cersat - Project 2025-07-31 publication 2025-07-31 publication geonetwork.thesaurus.local.theme.cersat_project Less than 6 hours Cersat - Latency 2024-07-26 publication 2024-07-26 publication geonetwork.thesaurus.local.theme.cersat_latency /Ocean Temperature/Sea Surface Temperature /Ocean Temperature Cersat - GCMD parameter 2024-01-04 publication 2024-01-04 publication geonetwork.thesaurus.external.theme.GCMDparameter /Imagery/Satellite Imagery Thèmes Sextant 2024-09-27 publication 2024-09-27 publication geonetwork.thesaurus.local.theme.sextant-theme L1 Cersat - Processing level 2019-05-17 publication geonetwork.thesaurus.external.theme.cersat_processing_level CDS-CERSAT Centre de données ODATIS 2024-10-16 publication 2024-10-16 publication geonetwork.thesaurus.local.theme.odatis_centre_donnees /Observational data/satellite Type de jeux de donnée ODATIS 2024-10-15 publication 2024-10-15 publication geonetwork.thesaurus.local.theme.type_jeux_donnee Sea temperature ODATIS aggregation parameters and Essential Variable names 2025-07-29 publication 2025-07-29 publication geonetwork.thesaurus.external.theme.NVS.OD1 Issue validityBegins validityExpires Update None Open Licence EUMETSAT Ocean and Sea Ice Satellite Application Facility, Full resolution Sea Surface Temperature metagranules (Metop-B) 2016-onwards, doi:10.15770/EUM_SAF_OSI_NRT_2013, data for [extracted period], [extracted domain], accessed [download date] from [distributor/distribution mean].
