ERA5 is the latest European Centre for Medium-Range Weather Forecasts (ECMWF) global atmospheric reanalysis of the period 1979 to present. This follows on from the ERA-15, ERA-40 and ERA-Interim re-analysis projects. This dataset collection includes data on surface and model levels on a regular latitude-longitude grid in netCDF from :
- a high resolution 'HRES' (31 km horizontal, 137 model level, hourly output) reanalysis model
- a reduced resolution ten member member ensemble runs, including data from all 10 members as well as means and spreads - produced to provide an uncertainty estimate for the 'HRES' output.
- initial release 'ERA5t' data
- re-run model output for 2000-2006 to address issues for this period - ERA5.1

Note, the parameter selection for the data held in the CEDA archive is not the full range of available parameters. Users requiring other parameters or data on alternative level types should seek these products via the Copernicus Data Store (CDS) - see linked data tool resource.

For further details of the datasets and CEDA's holdings please see the individual datasets linked to on this dataset collection record.
