CoD vs some other sims that model Kent?

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.

Worth noting that high pressure isn't particularly good for more localised air quality/visibilty as with very little wind (associated with high pressure systems) there's nothing to clear the air. A prime example of this is the recent urban smog alerts that were out across the UK. Smoke, sea fog, pollen/dust etc etc - all tend to linger at low altitude during periods of high pressure.

Also worth noting that fires aren't just for heat. I grew up in rural Somerset, and it would be unusual for fires not to be kept in throughout the year. The haze of woodsmoke on still summer evenings being a memorable and evocative feature Of course there are added benefits of the warmth in winter, but hot water, laundry, cooking etc all need to be done regardless of the season! Whilst I realise this isn't particularly applicable to London, it is applicable to the rest of the map that isn't London ...mind you, if the devs are worrying about getting the right levels of smoke from domestic chimneys then they'll already have done enough to get the game looking great!

Looks like I did get to opine after all

As a townie I can say that I thought woodsmoke was a brand of cigarette....London cooking and water heaters mostly powered by gas from the gasworks so while an indirect product of coal burning not requiring domestic use. Laundry only washed once a week anyway, I suppose everyone just got used to the pong. I was not aware that Zumerset yokels washed at all, but that is the wonder of forums, one learns so much!

Of course you are right about the high pressure - I just caught the end of the era of great London smogs and these always occurred during winter anticyclones.

Just wanted to add two piccies I happened to take while testing some stuff earlier





Three blue lines on horizon is the annoying ATI bug btw.

Peace out.
