Whats the actual measured data
As I have not read all posts I'm sorry if this has been covered before.
1 Has any research aircraft / UAV flown and measured the concentration of dust in the different areas around the volcano. I fail to understand how an area from 85 east to 55 west and 70 north to 40 south can all have dangerous concentrations of dust. As an astronomer last night the sky at my home in Essex was the clearest I've seen it in months.
2 Of course understand that directly downwind for a certain distance that there will be danger however what is the dispersal rate of the dust. Where I live in the UK every summer we have dust fall out from the Desert and nobody seems bothered by that.
3 What is the validation of the computer model used to show the rate of contamination / dispersion of the dust. i.e. how valid are these predictions. Somebody please tell me that this is a tested and proved computer model and not just a met mans whim!!!
4 I expect the 'Be safe police / regulators ' will jump on my mail but I'm schedule to fly to the far east on Tuesday and if I'm cancelled I want to know it was for the right reason and not some government nerd covering his butt.
