The current eruption on Iceland of Eyjafjöll has spread it's wings pretty
far. Radio Scotland reporting that Scottish airspace may be closed for the
rest of today, tomorrow and possibly beyond.
Rather hazy, overcast skies at the moment in the central lowlands, I'd be
surprised if that were a consequence of the ash.
Spectacular sunsets and sunrises possibly in store?

.... (0830Z): given that the air mass is coming out of the north, with
an upper flow out of the north as well, the 'blue' of the sky is much
milkier than I would have expected; difficult to judge whether that's
specifically to do with this event or a general pollution of the upper
atmosphere. As you write, the sunset tonight might be interesting.

I woke up at about 05:30 and noticed that the bedroom seemed somewhat
lighter than it would normally be at that time, even assuming a fairly
clear sky; it was more like I'd expect it to be some 30 or 45 minutes
later. I'm wondering if, even in the S of England, there could have been
enough high-level dust by then to reflect some sunlight downwards.

.... 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'.
