Alan, The soot layer is more likely to be on the ground, combined with large areas of misc. constructions and clearance of land mass. This would give a larger emission factor of the ground and a warming of the lower atmosphere. Maybe the global waring have a contribution from this also. The

Much simpler. Readjust the aircraft fuel controls to make a smokier exhaust. It will only cost 1-2% in additional fuel, and the particles wil be very small, practically invisible. The result, however, will be reflected sunlight and increased emission of IR radiation, thus cooling the earth,
