Thank you for your help, gansub, especially the link. Do you know of any experiments made to test dispersion of particles via jet streams or other air currents?

you need to give the particle size and the point of release or this will not be possible to answer.

Molecular-sized. I purposely chose no specific point of release, but for example's sake, how about several points of release: in Belize, in Kenya, in Estonia, in Papua New Guinea (chosen at random by looking at a Mercator map!) I'm curious to know if molecules travel around the entire globe via atmospheric circulation...

For fine particles to get dispersed throughout the globe via atmospheric circulation, in what level of the atmosphere would they have to travel?
