I believe I read somewhere that SO2 in low atmosphere leads to acid rainand other unwanted outcomes... But if released high in the atmosphere (ie deliberately using eg high altitude balloons) we can get the global cooling benefit without the negative effects.

IMO2020 - instead of switching to low sulfur fuel ships installed stack scrubbers to remove the sulfur and meet the new standard.. Cleaner air but it caused ocean pollution as the scrubbers discharged to the ocean. And the reduction in sulfur in the atmosphere increased global warming. Sigh! Side note: I once was told that most of the crude oil from Venezuela was high in sulfur.
