Karim,
I am afraid I am not familiar with either of those factors. The
cloudiness factor is a value from 0 to 1 that tries to estimate
how overcast the sky is so as to do a better job of splitting up
the total radiation into a beam component and a diffuse component.
Obviously a haziness and a scatter factor are related to the
cloudiness but I am afraid I do not know specifically in what way.
Perhaps there are other users who have some experience? If not
perhaps contacting the Meteonorm people might lead to a
suggestion.
kind regards,
David

Karim,
I would steer you towards using Type9 to read the data file
and
Type16 to process whatever solar radiation you might need.
kind regards,

Dear Trnsys users,
We are applying for an energy certificate, which needs a
thermal
simulation for a building with daily outdoor temperatures
ranging
between -8°C and -10°C and the solar radiation should be
assigned
certain attributes. While the location is in Vienna, we don't
really
know how to overwrite the data in the tm2 weather file of
Vienna in
certain days ? I tried to explore types 54, 99 and 109, but I
couldn't reach anything. Thank you in advance.
Best regards
Karim Rezk, MSc.

Hello David,
Thank you very much for your reply. Actually the sky radiation
settings I need to edit are: Haziness factor (Linke factor), which
has a range from 3 to 40, And Scatter factor (Reitz factor), which
has a range from 0 to 1. I found only Cloudiness in the
documentation of components in Type69. Do you know which input in
which Type is suitable for the mentioned factors ?
Best regards
Karim
