ERA5-Land

ERA5-Land samples are date-only files with global coverage. This release covers all daily input files from 2016-01-01 through 2023-12-31: 2,921 dates.

Sidecar Byte Ranges

Each tar shard has a matching JSON sidecar under tar_index/. Sidecars contain tar member byte offsets and sizes so readers can fetch individual samples without downloading whole tar files.
