Anenometer installation height

(1/5) > >>

I know the standard height is 10m (33ft) but that seems rather high!

I am able to install my anenometer well away from buildings or other obstructions - I'm going to mount the pole on a gatepost between two fields. There is a dry-stone field-wall only about a meter (3ft) high, and one medium tree about 50m (160ft) away.

With what I have available I'll fairly easily be able to install my anenometer at a height of over 4m (approx 13ft-14ft) or perhaps 5m (16ft). That is high enough, isn't it? What % difference in wind speed might I see if I went higher?

Thanks

See attached, from UK Met Office.

Hmm, so 4-5m is not really very high then...

Siting of weather stations, like life itself, is full of compromises. . .

Just do the best you can  :-)

And don't forget that table only applies to heights in an unobstructed open field. If there are obstructions then the factor will likely be significantly higher.
