ERA5 monthly data on pressure levels
This dataset is a Zarr mirror of ECMWF’s ERA5 monthly averaged data on pressure levels from 1940 to present.
It is designed to offer a fast, highly accessible alternative for querying ERA5 presure levels' monthly averaged data.
The dataset employs a spatio-temporal chunking scheme of 10 years × 60° latitude × 60° longitude. This corresponds to an array chunk shape of 120 (valid_time) × 240 (latitude) × 240 (longitude).
