The full ERA5 and ERA5T datasets are held in the ECMWF data archive (MARS) and a pertinent sub-set of these data, interpolated to a regular latitude/longitude grid, has been copied to the C3S Climate Data Store (CDS) disks. ERA5.1 is not available from the CDS disks, but is available from MARS (for advice on using ERA5.1 in conjunction with ERA5, CDS data, see "ERA5: mixing CDS and MARS data" in 82870405). On the CDS disks, where most single level and pressure level data parameters are available, analyses are provided rather than forecasts, unless the parameter is only available from the forecasts.
...
Information on all ECMWF parameters (e.g. columns shortName and paramId) is available from the ECMWF parameter database.Note: If a parameter name listed in the tables below does not have a Variable name in CDS, this means that this particular parameter is only available from the ECMWF MARS tape archive using CDS-API (see Data Organisation section above).

Parameters described as "invariants" below, are invariant in time. Parameters described as "instantaneous" below, are valid at the specified time. |
