Weather file input into SAM

Hi Paul,

I have a weather file with measurements (Year,Month,Day,Hour,Beam,Tdry,RH,Pres,Wspd) that works in the parabolic trough model (with a lot of warnings) but not in the empirical trough model, which is the one that I need, since it stops at error.

I don't know where the problem lies, but could it be related with the column variables I'm using? SAM calculates Tdew through Tdry and RH but maybe I have misplaced them! Could you please help me with this? I've attached here the .csv file!

Thank you very much for the attention!

Best regards,

Paul Gilman

Dear Francis,

It looks like there are some hours with atmospheric pressure of zero. I'm not sure if that is causing the simulation problems, but you might try changing those values to something reasonable, perhaps by interpolating from data points before and after those times.

Best regards,
Paul.
