[TRNSYS-users] Using radiation processor (type 99, type 16i or any ) with 1 min measured global and diffused radiation on horizontal surface

[David BRADLEY]

Ashmin,

   It may be possible to use Type99 in the manner that you want but I 
would recommend that you use Type9 to read the minute data and then 
Type16 to process it and compute the values on the other surfaces.

kind regards,

  David
