Fields are in monthly files with one variable per file. Files are compressed with a deflate level of 6 and chunked to the grid dimension. Please note that as 04-03-2021 all months in the database from 202101 up to 202102 are considered ERA5T.

Please note that even if the output of sst and siconc is available hourly from CDS API, it only change one time a day, so it was downloaded only at 12Z.

ERA5 (Hersbach et al., 2019) est la dernière version des réanalyses de ECMWF. Plusieurs sources d’informations sont assimillées dans le cadre de la réanalyse ERA5 comme les observations de stations de surface, les observations satellitaires, les METAR, etc. Les données ont été téléchargés à partir du Climate Data Store de Copernicus (C3S, 2017). L'extension 1950-1978 est considérée comme étant préliminaire dû à un problème avec la vitesse des vents dans les cyclones tropicaux. L'utilisation de ces données pour l'étude des cyclones tropicaux n'est donc pas appropriée.

ERA5-Land (Muñoz Sabater, 2019) est une simulation hors-ligne du modèle de surface à 0.1° qui est forcé par les réanalyses ERA5. Il n’y a pas d’assimilation de données. Toutefois, les observations atmosphériques s’y retrouvent indirectement via le forçage. Ces données peuvent être très utiles dans des endroits où il y a peu d’observations au niveau de la surface. Les données ont été téléchargés à partir du Climate Data Store de Copernicus (C3S, 2019)
