The information is only available in Norwegian. You have to be able to understand Norwegian or get someone to translate the requirements and regulations into your language. It is very important that you understand and follow the guidelines! We regularily monitor the downloads of our XML-files, and will block you without warning if you don't follow the requirements.
We are sorry that this information is not available in English. yr.no is financed by Norwegian tax and license fee payers, and our main focus is Norwegian forecasts and services, although we do offer forecasts for every country and all major cities of the world. We are afraid to get overloaded with traffic if we translate the guidelines and promote the free weather data service in English.
