Hi everyone
I'm currently working on predicting the climate change impacts. I'm using LARS-WG (Weather Generator) a statistical downscaling model. LARS-WG takes four parameters as inputs. Maximum and minimum temperature, precipitation and solar radiation. If solar radiation is not available, sunshine hours can be used. LARS-WG receives these parameters on a daily basis. I saw some websites and some Educational videos that receives sunshine hours on an average monthly basis. But I'm not sure about that. Even in LARS's help, this issue has not been mentioned. So if anyone sends me an authoritative article that describes it, I will be very grateful.
Best Regards.
