I wonder whereabouts on the airport the weather station is actually
located? Yes, I could check Google Maps, but the area is so large, it'd
be a needle-in-a-haystck search.


The meteorological instrument enclosure is on the north side of the airport.
It's about 130 metres north of the edge of the northern runway and about 20
metres south of the northern perimeter road. It is about 180 metres ESE of
the northern entrance to the tunnel at the south end of the M4 spur.
Co-ordinates are 51°28'45"N 0°27'2"W.

Thanks - I think I've got it now.


On Google Earth it's fascinating to see how Heathrow has developed over the
years. There's imagery for various years back to 1999 and, somewhat
surprisingly, pretty good imagery for 1st Jan 1945. The 1945 imagery covers
some quite large parts of the country. Getting a bit off-topic now but the
expanse of Croydon Airport stands out on the 1945 imagery though it was clearly
no longer operational. Comparison of the 1945 imagery with present day imagery
shows that the extreme SE end of the runway at Croydon still exists. It has a
very distinct white circle on it today. Looking on Google Streetview it can be
seen from the A23. Nice to see that a bit of history has survived.
