When I entered the coordinates and imported Meteonorm 8.0, "Meteonorm 8.0 (1981-2009), Sat = 23%" was obtained.
What kind of calculation is the Monthly meteo (Global irradiance, Global diffuse, Temperature, etc.) of this "Meteonorm 8.0 (1981-2009), Sat = 23%" calculated?

Is it the average value of station data in several nearby locations?
Or is it the value calculated by the mathematical model?

Thanks,

Hello,

Sat = 23% means that the share of satellite data when interpolating is 23%, the rest corresponds to station data, interpolated from nearby stations. Meteonorm does use a mixture of satellite and station data. The further one is from the stations the greater the weight of satellite data.
