I think I have stumbled upon a new opportunity that you may or may not want to pursue. The Consortium for Small-Scale Modelling (COSMO) weather model is a nonhydrostatic limited-area atmospheric prediction model. It forecasts most of Europe. There is a free license available for research applications or for developing countries. Or the paid license is available for 20000 Euros a year. http://www.cosmo-model.org/content/default.htm
i think icon is free
@ivo True that. After a lot of looking, I finally found out how you could access the Deutscher Wetterdienst weather data. You just need to create an account in the links provided. Hopefully, you will be able to use the data I provided. I've checked, it should be available in XML format. The ICON model should be in there.
