ERA5 hourly data on pressure levels

This is a subset of ERA5 reanalysis atmospheric quantities on pressure levels derived from ERA5 hourly data on pressure levels. The subset only includes pressure levels 1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20, 10, 5, 1 [hPa].

Data are available from 1940 until the last closed month and updated monthly.

They are presented as a ARCO Zarr archive optimised for spatial 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-pressure-levels-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.
