ERA5 hourly data on single levels
Here we propose a subset of ERA5 data for world atmospheric, ocean-wave and land surface quantities called ERA5 hourly 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 access
import xarray as xr xr.open_dataset( "https://data.earthdatahub.destine.eu/era5/reanalysis-era5-single-levels-v0.zarr", storage_options={"client_kwargs":{"trust_env":"true"}}, chunks={}, engine="zarr", )
