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). Une correction a été faites par ECMWF pour les années 2000 à 2006 dû à un biais froid dans la stratosphère.
3-D fields (RPN only)
1-hourly from 1979 to current. We keep adding recent months upon request.
The following fields are available on these pressure levels:
1000, 975, 950, 925, 900, 875, 850, 825, 800, 775, 750, 700, 650, 600, 550, 500,
450, 400, 350, 300, 250, 225, 200, 175, 150, 125, 100, 70, 50, 30, 20, 10, 7, 5, 3, 2, 1
| TT | air temperature [°C] |

SST & sea ice fraction (RPN only)
Even though these fields are available 1-hourly, they change over ocean only once a day between 22Z and 23Z. Therefore we only have these fields once per day at 12Z.
| TM | sea surface temperature [°K] |
| GL | sea ice fraction [0-1] |
