I’ve been using Dragonfly recently to generate “urban” weather files from rural mesurements (using UWG).
I realized that my conception of “rural” was rather vague, so I wonder if there is a rule or maybe some good practice regarding the choice of the rural weather file.
Here is the issue in my specific case : there is a weather station in park 2km away from my urban site. I first used it to run the UWG, then I realized that this park was very likely affected by the global UHI effect (since it is located in the city).
Therefore I think I have to use an airport weather file. The closest one available is not affected by the UHI, but it is located around 20km away…
What do you think? I guess the main criterion is the absence of UHI, so I’d go with the airport EPW, but I wonder is someone had the same problem.
Thanks in advance.
