A large-scale nuclear war would inject smoke into the atmosphere which could fall out onto snow and ice. A global energy balance climate model is used to investigate the maximum effect these "dirty snow' albedos have on the surface temperature in nuclear winter simulations which span several years. These effects are investigated for different nuclear winter scenarios, snow precipitation rates, latitudinal distributions of smoke, and seasonal timings. We find that dirty snow, in general, would have a small temperature effect at mid- and low latitudes but could have a large temperature effect at polar latitudes, particularly if the soot is able to reappear significantly in later summers. -from Authors
