We get a lot of stuff from various think tanks on what the outcome of a nuke strike would be, and frankly the scholarly work is usually pretty dodgy.
However, the very respected Atmospheric Chemistry and Physics Journal has published a paper on something that interests us in this field with up to date academic modellling and no political bias.
It's
Toon, O. B., Turco, R. P., Robock, A., Bardeen, C., Oman, L., and Stenchikov, G. L.: Atmospheric effects and societal consequences of regional scale nuclear conflicts and acts of individual nuclear terrorism, Atmos. Chem. Phys., 7, 1973-2002, 2007. and goes into detail on the short, mid and long term effects of tactical strikes on cities. A must-read.
