Ensemble spread of ERA5 hourly data on single levels

This is a subset of the ensemble spread for ERA5 single levels quantities ERA5 hourly data on single levels.

The data are available from 1940 until the last closed month and updated monthly. They are presented as a ARCO Zarr v3 archive optimised for time analysis.

Accessing this dataset requires a Zarr v3-compatible library (e.g., zarr-python >= 3.x). Python users can upgrade via pip install "zarr>3".

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/era5-single-levels-ensemble-spread-v0.zarr",
5    chunks={},
6    engine="zarr",
7    zarr_format=3,
8)

Method 2: advanced access

The Python snippet gather the token from a netrc file.

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

1import xarray as xr
2
3xr.open_dataset(
4    "https://api.earthdatahub.destine.eu/era5/era5-single-levels-ensemble-spread-v0.zarr",
5    storage_options={"client_kwargs":{"trust_env":True}},
6    chunks={},
7    engine="zarr",
8    zarr_format=3,
9)
