> Hi all,
> The sky temperature module (type 69) provides two

> between sky diffuse and total readiation; ii) by
> reading the cloudiness factor from a file.
> I would like to use the second option by reading the
> total sky cover and opaque sky cover from a TMY2
> weather file using type 89d. The problem is that I
> don´t know the equation to obtain the TRNSYS
> cloudiness factor from the two read fields (total
> and
> opaque sky cover). I have searched for information
> in
> the TRNSYS documentation but no success.
> Thanks for your help,
