# CREST forcing (parquet)
EF5/CREST hourly forcing for CONUS, 2016-present, packed as **one tar per variable/year**.

| dir | variable | source | cadence |
|-----|----------|--------|---------|
| `mrms/` | precipitation | MRMS QPE (corrected) | hourly |
| `temp/` | 2 m temperature | NLDAS-2 FORA | hourly |
| `pet/`  | potential ET | FEWS NET daily PET | daily |

Each `*.tar` expands to individual `.pqf` (Apache Arrow parquet) grids readable by the
EF5 v4.5 native parquet reader. Used by the Space `vincewin/CREST_AI`.

Download + extract one year, e.g.:
```python
from huggingface_hub import hf_hub_download
import tarfile
p = hf_hub_download("vincewin/CREST_data", "mrms/mrms_2023.tar", repo_type="dataset")
tarfile.open(p).extractall("forcing/mrms")
```
