Haze is visable in these shots from summer 1940.
Very nice photos, thanks..... but except for the first one, they could not have been taken before 7th September since there are extensive areas of bomb damage.

Anyway, they do not address the question of haze since they may well have been taken on cloudy days which are the norm in the UK, due to the prevailing damp westerly airstream off the Atlantic, as we all agree.

The issue is the haze level during periods of high pressure, which is what CoD with a weather setting of "fine" and no clouds should be emulating. IMHO it is about right, but the London area should have an overlay of grey haze, fairly thin from May-October and thick and horrible in November-April.

BTW Although coal was not rationed until 1941 it was in scarce supply in London during the BoB as the LW had been sinking the coal convoys, so the power stations had first priority IIRC (not of the war, of a source ). As a child in London during the 50s I can assure readers that only the richest and most extravagant would have lit coal fires during the summer months indeed until until well into October. We wore extra sweaters on chilly days.
