Well that is good news, however even if it is blown out to sea so to
speak, it still must rise to the upper atmosphere and stay for quite
awhile. I wonder how long it takes to dissipate.
This would also go in line if a meteor would hit the earth and spray
dust and smoke into the atmosphere. I am sure that scientists have
studied the effects of volcano ash in the atmosphere, to calculate
how long it would take to dissipate but not sure what their findings
are.

I am sure there is a great difference. Much like when the
meteorologists say x% cloud, as astronomers take it as a washed out
observing session.

Has there been any measurement on what the concentration is like.
Much like a smog count ? I think in Los Angeles they have a smog
report throughout the day, just wondering if they are counting the
smoke the same way.

It will be clear soon. It must be clear for July: ) Hope you can
make it to the East Coast NAMN get together.
