I 100% understand what you are saying, you are trying to estimate the wind above treetop height, right?
To me it’s like saying your temperature is 35F on a night the station says 45F… but saying “well if the trees weren’t there and it was open to the sky above, I’d have radiated more.”
Do you live 100 feet up above the canopy? I feel like that caveat is important to mention.
