I dont understand why 30 feet is the offical height to measure wind?
The higher up you go, the wonder it is so how does 30 feet give a real indication of wind? Go 50 feet and its higher again, 20 feet its lower?
Would not a real indication of true wind with no obstacles be 5 ro 6 or so feet the more true to wind speed indication?
I cannot see how it why 30 feet is used unless it’s to be above every obstacle possible, but being g higher you get more wind, so how can even 30 feet be a true real indication?
I have mine at 9 feet and to me gives a true wind speed indication than at 30 feet.
Also for a 5 in 1 they always recommend a height of 10 feet as ideal.
Anything higher than 10 feet and weather flow your getting false rain. So it’s a compromise.
Why does weather flow, if offical wind speed is 30 feet,? Then if your 10 feet then be able to calibrate it to tell your weather flow its 30 feet up tell it how high your station is and self calibrates to indicate the same type of wind speeds as though your 30 feet up or your station learns the average wind speeds over time and works out the speeds if your station was 30 feet up?
You already ask for height of sky above ground so surely could not be hard for your station to work out at 30 feet how strong the wind would be and adjust accordingly.
I have found through experimenting with 5.1 stations 10 feet is the optimal height and gives the best all round results apart from wind of you got obstacles. Temps, dew point, humidity and rain are the best compromise at this height and closer to offical temps and rainfalls, etc.
The higher you go the higher the wind is rain is more angled so can see how this as well as false rainfall will through weather flow off.
I find mine accurate at 9 feet so far.
Have had 3 days rain and it’s better than my ambient and vantage vue and raincheck does not work over here in New Zealand as far as I know?
