Nonsense. The cooling is less effective at higher altitudes, and all the sulfate currently in the atmosphere provides a forced cooling of .4 W/m^2 vs the greenhouse gas warming of 2.4 W/m^2. The cooling relies on atmospheric water which decreases the higher you go.
We would need to dump way, way more sulfates/sulfites into the air than we do currently.
