To what degree of "likely" are we talking about? Also, would there be issues with clumping which could create condensed areas within the SRM layer which could mimic PSC? Further, will the SRM particles *augment*PSC's warming ability when the 2 mix?
The fact that the IR energy will be coming in under the SRM layer and the particles would be reflecting IR down and PSCs are well known for trapping heat due to that same issue, should we not have a detailed understanding of the full dynamics. Does anyone have data on the actual polar atmospheric temperatures during the full Pinatubo event?
