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 single level and pressure level data are available, analyses are provided rather than forecasts, unless the parameter is only available from the forecasts.

Data ERA5 data on the CDS disks can be downloaded either from the relevant CDS download page or using the CDS API.

Getting data from the CDS disks provides the fastest access to ERA5 data.

ERA5 data in MARS can be accessed using the CDS API, but access is relatively slow.

titleData organisation on the CDS disks

ERA5 data on the CDS disks can be downloaded either from the relevant CDS download page or, for larger data volumes in particular, using the CDS API. Subdivisions of the data are labelled using dataset and product_type.

Datasets reanalysis-era5-single-levels and reanalysis-era5-pressure-levels contain the following product types:

  • reanalysis (sub-daily)
  • ensemble_mean (sub-daily)
  • ensemble_spread (sub-daily)
  • ensemble_members (sub-daily)

Datasets reanalysis-era5-single-levels-monthly-means and reanalysis-era5-pressure-levels-monthly-means contain the following product types:

  • monthly_averaged_reanalysis
  • monthly_averaged_reanalysis_by_hour_of_day
  • monthly_averaged_ensemble_members
  • monthly_averaged_ensemble_members_by_hour_of_day

Datasets reanalysis-era5-single-levels-preliminary-back-extension and reanalysis-era5-pressure-levels-preliminary-back-extension contain the following product types:

  • reanalysis (sub-daily)
  • ensemble_mean (sub-daily)
  • ensemble_spread (sub-daily)
  • ensemble_members (sub-daily)

Datasets reanalysis-era5-single-levels-monthly-means-preliminary-back-extension and reanalysis-era5-pressure-levels-monthly-means-preliminary-back-extension contain the following product types:

  • monthly_averaged_reanalysis
  • monthly_averaged_reanalysis_by_hour_of_day
  • monthly_averaged_ensemble_members
  • monthly_averaged_ensemble_members_by_hour_of_day
