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

Dear all,

I was using type 99 for reading the data and was using it as a
radiation processor (with hourly input data for global radiation on
horizontal and diffuse radiation on horizontal). But now I need to
validate my simulation with my experimental work . *I have weather
data from measurements (global radiation on horizontal and diffuse
radiation on horizontal) at 1 min interval for some  particular days.
* I couldn’t  obtain tilted surface radiation (radiation on the
building facade) within 1 min. data. My question is how to input 1 min
global and diffuse horizontal radiation data and get the value for
each facade of the building using the radiation processor (be it type
99 or type 16 i or any other radiation processor).

I tried to input the weather data similar to what we do for hourly
data by changing the hours in minutes as follows  but i couldn't get
any data for radiation in other tilted surfaces (building walls).

I am unaware of how to input minutes data in type 99 and get the
values of radiation on tilted surfaces (building walls)  . Please let
me know how to do it. I will be indebted.

Thanking you
