Spectral Correction without Precipitable Water Data

[td97]

I'm modeling a plant using First Solar modules and hoping to use the built-in spectral correction feature. My weather data provider does not include precipitable water but does include relative humidity.

When uploading weather data in the PVsyst standard format, relative humidity does not appear in the options for parameters to include that would be used by PVsyst.

How can I upload weather data that would be usable for this model?

Thanks!

Create a custom format to import your weather file, and include RH
