Data Sources

DMI provides weather forecasts from the HARMONIE AROME model with ECMWF IFS initialization. This is a collaboration of multiple European national weather services under the name "United Weather Centres-West" (UWC-West). Forecasts for Europe use 2 km resolution and provide a large range of weather variables. All data is updated every 3 hours and provides forecast for up to 2.5 days. After 2.5 days, Open-Meteo combines forecasts with the ECMWF IFS 0.25° model to provide up to 10 days of forecast.

You can find the update timings in the model updates documentation.

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: DMI provides direct solar radiation. Many other weather models only provide global solar radiation and direct solar radiation must be calculated user separation models.
Direct Normalized Irradiance (DNI): Although DNI is available, it has not been integrated. Open-Meteo uses solar position algorithms which calculate DNI from direct radiation with (almost) the same results.
Wind Direction Correction: Wind direction has been calculated from U/V wind component vectors. Special care has been taken to correct for the Lambert Conformal Conic projection. Without this correction, wind directions have an error of up to 15°.
Cloud Cover (2m): DMI provides cloud cover at 2 metre abouve 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.
