Went manually through the RS vs RSO graph for each day in February for the csu station. Counted anything over 75% as a sun hour. I got ~192 hours which is about 65% possible.
Seems too low especially since February felt like a sunny month and it was very dry. Hard to judge the accuracy though without doing more months but it’s a pain in the ass so I probably won’t do more months soon.

I don't see why you don't just use the daily mean solar radiation values and plug them into the sunshine calculator (after converting to MJ). I get 225 hours (77%) this way, which seems reasonable. |

I’ve tried that, none of the Fort Collins seem to hey reasonable values that way. The AERC and Christman field get <2800 hours a year, the CSU station gets over 90% sunshine some months and the Redstone RAWS also gets too low numbers. I could use the ARDC station near Wellington but I’d be hesitant to use something further out in the plains as that makes a big difference here. |
