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
