ASOS measures winds at approximately how many feet above ground?

Explanation:
ASOS winds are measured at about 10 meters above ground, which is roughly 33 feet. This standardized height (10 m) is used for surface weather observations like ASOS/METAR, providing a consistent reference for wind data in fire behavior calculations. Wind speed does change with height due to surface friction, but the 10 m measurement is the convention used for reporting and modeling, so 33 feet is the commonly cited equivalent.
