[TRNSYS-users] Fw: read weather data type9a

[David BRADLEY]

Saja,
   I would recommend that you start with JUST Type9 and an online 
plotter. Use the online plotter to make sure that the data reader is 
reading what you think it is reading. It can be tricky to get the data 
reader settings correct. For example, you do not want to interpolate 
solar radiation readings. You can interpolate temperature and other 
readings. There are also a number of parameters that tell whether the 
data in the file is given as average values over the data interval or 
instantaneous values reported at the end of the interval. Once you are 
certain that Type9 is reading the file in a way that makes sense then 
look very carefully at the Type16 parameters, especially if your data 
file does not start on January 1 at midnight. One of that parameters 
asks for the starting /day /of the simulation. Others ask whether the 
data being read is in solar time or local (standard) time and if it is 
in local time, what the difference in longitude is between the data file 
location and the standard longitude for the timezone. These must all be 
set correctly in order to avoid the kind of problems that you are seeing.

   If you are really stuck after working to get the parameters set 
correctly then you should send the project and data file to your 
distributor for assistance.
Kind regards,
  David
