Hello, I tried to import a file meteo ASCII with in input global irradiance on tilted plane measured, date, hour and minute and i saw that after conversion, PVsyst calculate ambient temperature. I would like to understand how the software can calculate ambient temperature starting from global on tilted plane(what kind of formula is used). Because i have ambient temperature measured too but the time step is different from global on tilted plane (global on tilted plane every minute, ambient temperature every 10 minutes) so i can't import ambient temperature at the same time with global on tilted plane. I hope I was clear. Regards, Fabio
