Comparison between METEONORM and SARAH3

[Loïs Masson]

Hello, 

Does anyone know whether Meteonorm or SARAH3 is the most accurate database for France?

Do you know of any scientific papers on this topic?

Thank you in advance.

Hello,

Indeed there can be big discrepancies between databases. It is very difficult to estimate which one is the best suited for a given project or location, and what the probable error is.

The following Help page provides comparisons of several databases across different sites:
