Our Weather Forecast API is based on high quality weather models. We optimize global forecasts to specific sites using Model Output Statistics. Our solar forecasts based on this methodology have earned top marks in benchmarks. For complex parameters such as wind fields or precipitation we rely on the COSMO-1 model. The model is specifically adapted to the alpine region and has a fine mesh of only 1 km.
Typical applications of the weather forecasts API are:
