API Response
Data Source
This API uses global UKMO Global 10 km weather forecasts and combines them with high-resolution UKV 2 km model for the United Kingdom and Ireland. Information about UKMO weather models is available here. For UKMO Global, values are interpolated from 3-hourly to 1-hourly after 54 hours and from 6-hourly data after 144 hours.
Note: UKMO open-data has an additional delay of 4 hours. The forecast is therefore not as accurate as it could be.
| Weather Model | Region | Spatial Resolution | Temporal Resolution | Forecast Length | Update frequency |
|---|---|---|---|---|---|
| UKMO Global | Global | 0.09° (~10 km) | Hourly, 3-hourly after 54 hours, 6-hourly after 144 hours | 7 days | Every 6 hours |
| UKMO UKV | UK and Ireland | 2 km | Hourly | 2 days | Every hour |
API Documentation
For a detailed list of all available weather variables please refer to the general Weather Forecast API. Only notable remarks are listed below
- Direct Solar Radiation: UKMO provides direct solar radiation. Many other weather models only provide global solar radiation and direct solar radiation must be calculated user separation models.
- Shortwave solar radiation: The Global UKMO domain does not include solar shortwave radiation. Therefore diffuse and tilted radiation are not available as well.
- Wind Forecasts at 100m and above: Wind forecasts at different levels above ground are only available for the 2 km UKV model.
- Cloud Cover (2m): UKMO UKV 2 km provides cloud cover at 2 metre above ground which can be interpreted as fog. This is remarkable, because only very weather models are capable of modeling low level cloud cover and fog with a good degree of accuracy.
