[TRNSYS-users] Raw weather data

[David Bradley]

Dimas,
 The combination of Type9 (generic data reader) and Type16 (radiation 
processor) might offer some possibilities. Type16 has modes in which it 
takes total radiation on the horizontal (and temperature and humidity if 
you have them as well) to come up with an estimate of total radiation on 
a tilted surface. Since you have beam on the horizontal and not diffuse 
on the horizontal, I am not entirely sure what to suggest. You might 
refer to some of the basic texts on radiation processing such as Duffie 
and Beckman's Solar Engineering of Thermal Processes for some possible 
correlations.
Kind regards,
 David
