ERA5 monthly averaged data on single levels

This is a subset of ERA5 data for world atmospheric, ocean-wave and land surface quantities called ERA5 monthly means data on single levels. The data are available from 1940 until the last closed month and updated monthly and are regridded to a regular lat-lon grid of 0.25 degrees.

They are presented as a Zarr archive optimised for time analysis.

How to download the data

The default (and preferred) way to access the data requires accessing the api.earthdatahub.destine.eu domain and a valid API key.

Method 1: quick access

It is possible to include the token directly in the URL.

1import xarray as xr
2
3xr.open_dataset(
4    "https://edh:<your personal access token>@api.earthdatahub.destine.eu/era5/reanalysis-era5-single-levels-monthly-means-v0.zarr",
5    chunks={},
6    engine="zarr",
7)

Method 2: advanced access

The Python snippet gather the token from a netrc file.

It's required to before running the code snippet below.
