<p>Huseyin,</p>
<p> I think that your point 2 is the right direction. You can read
your data (including GHI) using Type9 and then feed GHI, T, and RH
to a Type16 radiation processor. Type16 has a number of algorithms
for estimating solar on tilted surfaces. The most basic of these
requires only GHI but there is an improved algorithm that takes
GHI, T, and RH.</p>
<p>kind regards,</p>
<p> David</p>
