... now (1200Z), the sky is *very* milky-white; the distinction of the
Cu is similar to that you would get on a very warm, hazy summer's day
in late July or August, yet of course the air mass is coming from the
north. I've no doubt that there is some broader 'air mass' element,
but I think we're seeing the effect of the volcanic ejecta into the
upper troposphere/lower stratosphere.

On the other hand, the absence of aircraft vapour trails is also very
noticeable.

Are there measurements and records of solar intensity that would show
the effects of any 'global dimming'.
