Storage location
This dataset is stored in the East US 2 Azure region, in the following blob container:
https://metdatasa.blob.core.windows.net/metoffice-20cr-ds
Allocating compute resources in East US 2 is recommended for affinity.
How the data is organized
The root of the container includes folders for each time scale: hourly, 3hrly, 6hrly, daily, and monthly. Each of these folders represents a Zarr dataset, with one variable or aggregated variable per folder. For example, the folder:
https://metdatasa.blob.core.windows.net/metoffice-20cr-ds/daily/surface_temperature_max
…contains maximum surface temperature at daily granularity.
