Recently when driving around I've noticed what appear to be weather stations
positioned by the side of roads. Trouble is you see one then you start
noticing them all over the place !!!

They are all on poles about 10 ft high, look to be solar powered, and have
various instruments on. These are presumably for measuring wind strength,
direction, temperature, etc. From what I can see they aren't the air quality
measuring stations that are also cropping up.

I've noted them on the M4 (betwen Reading and Newbury) , M4 spur road to
Heathrow, A22 Godstone, Surrey.

Hopefully someone will be able to enlighten me as to what they are used for
and who they belong to.

Thanks
