|
| ## 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. |
