Those are the famous TTAPS papers:

With an update here:

Nuclear Winter: Physics and Physical Mechanisms

R.P.Turco, O.B. Toon, T.P. Ackerman, J.B. Pollack, C. Sagan
Ann. Rev. Earth Planet. Sci. (1991) 19, 282-422.

It's a dense paper, well-written, and I expect you will find what you are
looking for there. I purchased the paper last summer, thinking about the
Antarctica volcano: Erebus' strombolian eruptions, and what might be the
transport mechanisms of dust into the upper atmosphere. I'll email it to
you.
