Note:
The wind gust is also affected by the wind speed

Discussion
: Wind speed and wind gust are adversely
affected by installation constraints. The rule of thumb is to
install the weather station four times the distance of the height
of the tallest obstruction (for example, a 6 m house would
require an installation 24 m away).
In many instances, due to trees and other obstructions, this is
not possible. The wind speed calibration allows you to correct
for these obstructions.
In addition to installation challenges, wind speed bearings (any
