Artemi,
TMY2 files are just plain text files, you can open them in
Notepad. However, due to the format, they're difficult to read like that. Excel
can open them and be set up to split the data fields properly, or you can just
use a template like this one: http://sel.me.wisc.edu/trnsys/weather/tmy2.xls
Type 109 knows that the input from a TMY2 file is in W/m2, and
converts its output for kJ/hm2, you shouldn't have to change anything for it to
work properly. What exactly is the problem you're getting?

Dear David and TRNSYS users Thanks again for your helpful advice.
I think I found the reason that gives
me strange results. I created a *.tm2 file of meteorological data using
Meteonorm software. The created file gives the radiation in W/m^2. The component
that reads this file (type109-TMY2), has by default the unit of solar radiation
in kj/hrm^2. Have you got any idea about how can I change this, without changing
the whole proforma (this is because the proforma has already a lot of changes
that I don’t want to be change in this
project). Is there any way to view this *.tm2
file? (maybe another software?). I connect it with type65a, in order to view
some data, but it seems to be quite different in comparison to the preview
results of Meteonorm. I think that this is the reason that gives me “weird”
results in my simulation. Thank you for your helpful
advices. Best regards, Artemi Spanaki check out the rest of the Windows Live™. More than mail–Windows Live™ goes way beyond your inbox. More than messages
