[TRNSYS-users] RADIACTION PROCESSOR

[David Bradley]

Javier,
  The solar constant parameter in Type16 is the amount of solar radiation 
falling on a 1 m2 surface outside the earth's atmosphere. There are a 
number of different estimates of this amount dating back to various 
research projects before the birth of TRNSYS. If you are getting only 6 
warnings about radiation exceeding extraterrestrial during the course of 
your simulation, I would not worry too much about it. The math and sun 
earth geometry can cause such calculation. If you are getting hundreds of 
those warnings then that is a good indication that there is something 
incorrect about your input file.
Kind regards,
  David
