Meteonorm dataset limitations

Meteonorm dataset limitations

The key limitations of Meteonorm's representativeness lie within the use of 1) interpolated and 2) synthetic data. Interpolations rely heavily on surface observation data, which are not equally distributed. Synthetic estimates are useful when high quality direct observational data does not exist. However, given the presence of a global fleet of high resolution weather satellites that directly image cloud cover - this is not the case.

Global Solar Irradiance Forecasts and Historical Datasets

When we first launched the Solcast API in early 2017, the Solcast team was excited to learn more about the market for historical and forecast solar irradiance and solar power data services. Now, 18 months later, with nearly a thousand users across five continents, we see no better way to launch our company blog than by thanking those users for their commitment to the integration of solar energy, and for being such forward-thinking early adopters of the Solcast API. So - Thank you!
