Haze?

[Tudor Hughes]

There is very little blue in the sky here.  The sunlight is weak and yellowish (1630Z) and the sky is completely uniform so I doubt it's a layer of Cs.  Is this just thick haze?  If so, at what altitude and where does it come from?  I shouldn't  need to be asking this at my advanced age (81) but I am genuinely puzzled.

It's been the same here Tudor, this morning the sky was just a very weak blue colour, but apart from a few very small Cu, no real evidence of cloud for a good 2 hours. Same again early afternoon as the photo in my earlier post today shows. Visibility at ground level much less than I expected as well. Really strange in a WNW airflow which tracks right back across the Atlantic.

And the same here too. Sun shining through a cloudless thick haze that turned the sky white. It seriously impacted on the strength of the sun with the UV maximum today of 4.7, well down on previous days which got as high as 8.4 just 3 days ago.

The dry theme continues with 17 mm since mid-July. Only 6 mm so far this month.

I have been told that the cause of the haze is dust from the forest fires in Canada.  Similar sky in Brussels today as well.
