very nice

Do you have topography?
No. My model doesn't take it into account so I just ignore it. In theory it shouldn't be too hard to generate a grid cell topographic map from open source data though? I've never tried.
For a still-in-progress project related to nuclear burning, I have a lot of datasets relating to land cover and urban build-up. Someday hope to integrate those into things (have a student working on it)...
“nuclear burning” is a fun phrase. 
It's fun to be able to say, "ah, yeah, that comes out of the nuclear burning account."
Can someone define "nuclear burning"? Does this refer to things igniting?
Right. I'm interested in coming up with rough, on-the-fly numbers for how much smoke would be created from any given nuke going off, based on terrain parameters (e.g. grassland vs. desert), density and flammability of buildings, etc.
If I could get reasonable back of the envelope numbers on the fly (e.g., less than a second of calculation per detonation, like the casualty numbers NUKEMAP can already generate very quickly), I could do interesting things with that.
