Note: is on the roof of a WWII underground bunker. May or may not be heated today, is under many feet of earth and concrete, negligible thermal conductance but leakage via ventilation and services might be significant.

UHI, local is undecided, distance, 50km centre of London.


Google Street view revealed the site in the woods has a… windsock. Maybe that’s regulations, Sir.

A little fun nearby.

    On several occasions recently I’ve notice reports this met site is lowest day maximum, the case yesterday

    “24 hours ending 2100 on 9 Feb 2013:
    UK Highest max 0900-2100 10.6 °C Isles Of Scilly
    Lowest max 0900-2100 1.5 °C High Wycombe
    Lowest min 2100-0900 -3.1 °C Writtle
    Highest rainfall 2100-2100 13.2 mm Giants Causeway
    Sunniest 2100-2100 8.1 hours Leconfield”

    This points to poor exposure. The site is essentially in a wood which has been growing for many years, the site origin was a camouflaged command centre during WWII.

    A close look around via Google Streetview with this problem in mind points to topography as an additional site feature, on the edge of a wooded escarpment. Figuring out if and why the site is a little odd would I think need the full site data and local knowledge.
