Hi all, I'm doing a simulation in permanent regime, and I need the results of ESP-r algorithm for the sky temperature. I see from the help that with trace facility we can get the sky temperature, but In fact I don't understand very well how it works. I was trying also to put simulation in mode 3 to get all temperature analysis, but I didn't get the sky temperature. Can someone give me a more easy way to get hourly sky temperature in ESP-r?
