Weather models and updating frequencyEdit
Yr.no generates weather forecasts for millions of places around the world. Its 3-day forecast uses two different weather models with a 2.5 km resolution in Scandinavia and the Norwegian islands, and for other places, the ECMWF's IFS model in high-resolution configuration (HRES), with a 9 km resolution.
For the 10 day forecast, yr.no employs the ECMWF-ENS model with a 18 km resolution for Norwegian territories, and for the rest of the world, IFS-HRES with a 9 km resolution.
Outside of Scandinavia, the 3-day forecasts are updated every six hours, and the 10-day forecasts every 12 hours.
In addition to data from the Norwegian Meteorological Institute, yr.no uses open data from various collaborators such as
- European Organisation for the Exploitation of Meteorological Satellites
- The Norwegian Polar Institute
It also collects information from different types of private weather stations.
