How Far Do Aerosols Carry?

Josh Marshall at TPM links to an article which seems to take aim at the science behind the 6 foot distance, arguing it's old science and modern instruments can offer more accurate measurements.

I'm no expert--Marshall repeats the suggestion if you're close enough to smoker to smell the tobacco, you're likely too close for covid-19.  That's the sort of layman's measurement which appeals.  Might not be right but appeals.  I'd offer another layman's measurement: in season 3 of the Last King some episodes are set in winter.  It appears they shot in winter, because the exhaled breaths of people and horses are very visible.  Hard to guess the distance traveled, but often likely over 6 feet.
