This endpoint returns analysis and reanalysis gridded data as Zarr (default) or NetCDF.
A source parameter is provided in the URL path to specify which data source to retrieve from. Available variables can be found via the Variables endpoint. Use the Available Times endpoint to discover which timestamps can be queried.
