Zhe,
Are you speaking about the calculation performed in Type54? If so, the algorithms are discussed in section 4.10.4 of the volume 4 Mathematical Reference manual.
Regards,
David

Dear All,

Thanks for your time.

I am looking for the inside knowledge of how TRNSYS works out monthly clearness index values for a year from input monthly solar radiation values for a year?

Is there any document or journal paper explains it?

Thank you very much for your help.

Zhe Li
