Currently, the family of ERA5 datasets is comprised of ERA5, ERA5.1 and ERA5-Land.
ERA5 back extension (preliminary version), from 1950 to 1978 was made available separately from ERA5. Reason for this is it appeared to suffer from tropical cyclones that are sometimes unrealistically intense. This has now been resolved for 1950 to 1978. Access to this preliminary product was discontinued on August 15, 2023.
Usually, access to the family of ERA5 datasets is through the C3S Climate Data Store (CDS). The complete datasets are held in ECMWF's tape archive, MARS, but a sub-set of the datasets (all of the dataset for ERA5-Land) have been interpolated to a regular latitude, longitude grid and put on the CDS disks. Data access from the CDS disks is faster than from MARS, so if possible it is better to retrieve the data from the CDS disks. Please see the Climate Data Store (CDS) documentation for further details.
The sub-set of data on the CDS disks comprises some single level parameters and pressure level parameters. The data are available hourly throughout the whole period. Monthly mean data are also available, in two forms: monthly means (of daily means) and monthly means for each hour of the day (synoptic monthly means). The CDS catalogue entries are:
The complete ERA5 dataset, at full resolution on the native grid, is stored in MARS. ERA5 data that has not been made available on the CDS disks includes:
For ERA5-Land, the data comprises some single level parameters.
The data are available hourly throughout the whole period. Monthly mean data are also available, in two forms: monthly means (of daily means) and monthly means for each hour of the day (synoptic monthly means). The CDS catalogue entries are:
