Ensemble spreads of ERA5 single levels

Name: Ensemble spreads of ERA5 single levels - Earth Data Hub
Creator: ECMWF

This is a subset of the ensemble spreads of ERA5 hourly data on single levels from ECMWF.

Built upon its Climate Data Store (CDS) version, this dataset is distributed as a Zarr archive. It is designed to offer a fast, highly accessible alternative for querying ERA5 global reanalysis's ensemble spreads.

📊 Chunking Specifications

To optimize data access performance for regional and time-series analyses, the dataset employs a spatio-temporal chunking scheme of 180 days × 20° latitude × 20° longitude. This corresponds to an array chunk shape of 1440 (valid_time) × 40 (latitude) × 40 (longitude).
