Altitude 236 metres.

Provisional estimate Class 3, fails Class 2 on buildings and paving within 30 metres. (229.6+53.8+85.3+63.6+9.5) / 2827.4 =15.6%, limit 10%

Please discuss whether this is a fair assessment. Basis is image below, click for larger.

Note: the location of the Stevenson screen is uncertain. If that is the current met enclosure it is rather small. The site is hidden from overlook but photos are needed. There might be images published by one of the organisations involved. Aerial is less likely because this region is notoriously cloud covered and wet.

See comments for images.

UHI, local built environment otherwise none.

This is one of or the most major Met Office sites / observatories in the UK, co-managed by BGS (British Geological Survey). The latter part best explained by BGS http://www.geomag.bgs.ac.uk/operations/eskdale.htm

The area might have unstable vegetation from human changes. I also note the WMO number has suffix 0 which means or ought to mean the primary site but the long site history will mean many equipment changes etc. The lack of space for a Class 1 station is mostly a matter of changing Standards over the years.

The original thermometers were almost certainly much closer to the buildings so there was less walking in foul weather, is now automated.

Lets see what people dig out.

    A higher resolution picture here, When blown up to 400% I think the Stevenson screen may be halfway along the path and not at the end.

    Old photo here, Hard to tell from the perspective if that is the diagonal path seen today or whether it is the one that runs straight out from the building

    I agree especially given the elderly image shows a wide screen as does the first.

    Long time since I did any photo geometric work, sure there are tools which help these days. Maybe someone can figure it out.

    Quick guess, stays Class 2, to which I add the slopes etc. do not help instrument exposure.

    Cracked it, 34 seconds into this video. The Stevenson screen is indeed halfway along the diagonal path.

    Elementary my dear Stevenson.

    Well done Caz. 😉

    Seem to have got away with an offline edit and redo.
