## Dataset Card

By Mathias Pedersen, published under cc-by-4.0, revision 04650bd03f68.

Training data and model artifact dataset for the Aarhus weather pipeline. Maintained by Ciroc0.

### Primary files

| File | Purpose | Produced by |
| --- | --- | --- |
| training_matrix.parquet | Current source of truth for training rows and causal observation context | dmi-collector |
| model_registry.json | Active bucket registry per target | dmi-ml-trainer |
| model_meta.json | Training timestamp, sample count and training window | dmi-ml-trainer |
| temperature_models.pkl | Temperature bundle | dmi-ml-trainer |
| wind_speed_models.pkl | Wind speed bundle | dmi-ml-trainer |
| wind_gust_models.pkl | Wind gust bundle | dmi-ml-trainer |
| rain_event_models.pkl | Rain event bundle | dmi-ml-trainer |
| rain_amount_models.pkl | Rain amount bundle | dmi-ml-trainer |

### Compatibility files

| File | Status | Notes |
| --- | --- | --- |
| data.parquet | Legacy | Still readable by compatibility code |
| xgb_model.pkl | Legacy | Older single-target artifact, not the current multi-target source of truth |
