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

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