Ben, if you ever do get around to running the model with PSCs, I would be interested in viewing the results and learning more about the details of your model.
As I have had my concerns over this sulfur/PSC issue for years, I've read up on a number of models specifically crafted for PSCs and most authors on the subject believe PSCs need unique treatment. I just don't see how your type of model can depict the full range of PSC factors. Just on the issue of topography alone, which some PSC specific models factor in as topography is a factor in some PSC formations, seems to be absent within this new model. I would like to know how your model can fully depict the many factors related to PSCs. As to the BC, you may wish to adjust your model for wetted BC even if for the only the reason that such modeling may represent a first effort of its kind. I guess that, and that alone, would give it value. As to the valcanic sulfur thing, there would seem to be far more wetted BC being released each year from ffs and fires than valcanic sulfur. Why not model for wetted BC?
