Release Notes

  • global_availability_index.parquet -> satellite/metadata.parquet

Layout

  • satellite/metadata.parquet: satellite sample metadata.
  • satellite/shards/: WebDataset tar shards.
  • satellite/tar_index/: byte-offset sidecar JSON for each satellite tar.
  • era5_land/metadata.parquet: ERA5-Land daily metadata.
  • era5_land/shards/: ERA5-Land daily WebDataset tar shards.
  • era5_land/tar_index/: byte-offset sidecar JSON for each ERA5-Land tar.

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.
