This is a fairly well-known phenomenon, and sometimes comes up in geoengineering discussions. It’s dangerous ground; thing about fine particulate matter is you generally don’t want to breathe it.

Ideally we would want a fine particulate that stays high in the atmosphere, and doesn't come down where we need to breathe

Fine particulates aren't a problem if you wear a gas mask though.
