## Dataset Card

By Mathias Pedersen, published under cc-by-4.0, revision a379f66cca26.

Prediction and frontend contract dataset for the Aarhus weather pipeline. Maintained by Ciroc0.

### Primary files

| File | Purpose | Produced by |
| --- | --- | --- |
| predictions_latest.parquet | Current future + verified prediction store | dmi-collector |
| frontend_snapshot.json | Primary integration contract for the Vercel frontend | dmi-collector |

### Compatibility files

| File | Status | Notes |
| --- | --- | --- |
| predictions.parquet | Legacy | Still read by compatibility code |
| history_snapshot.json | Legacy | Only used by older frontend fallback logic |

### Update pattern

- predictions_latest.parquet is rewritten on scheduled prediction runs
- verification updates actual columns once the target hour is in the past
- frontend_snapshot.json is regenerated after prediction and verification writes

### Schema highlights for predictions_latest.parquet

- target_timestamp
- reference_time
- lead_time_hours
- lead_bucket
- prediction_made_at
- city
- verified
- dmi_temperature_2m_pred
- dmi_windspeed_10m_pred
- dmi_windgusts_10m_pred
- dmi_precipitation_probability_pred
- dmi_precipitation_pred
- ml_temp
- ml_wind_speed
- ml_wind_gust
- ml_rain_prob
- ml_rain_amount
- actual_temp
- actual_wind_speed
- actual_wind_gust
- actual_precipitation
- actual_rain_event
- actual_rain_amount

### Snapshot contract

frontend_snapshot.json is the main public-facing contract and contains:

- location metadata
- generated timestamp
- target labels and explanations
- current weather block
- 48-hour forecast rows
- historical backtest payload
- verification metrics
- lead-bucket summary
- feature importance
- model info
- alert rows
