It's really complicated, Hugh!
10 metres EFFECTIVE height, so any nearby trees and buildings need to be taken into account within 10x their height from the anemometer.
Some anemometers look really high - say 20 metres, but their effective height is only 10 metres.
Have a look at the Observers' Handbook if you can, it's all in there.
Only mean speed should be adjusted, gusts remain as read.
Best wishes,
