@wellerstein Why does the 100% probability for 3rd degree burns energy density vary by height and yield?
Yield changes both the intensity of the heat and the duration of the thermal pulse, which means you need different amounts of heat energy to burn (so for 150 kt you need 10 cal/cm^2, for 15 kt it is only 9 cal/cm^2 to burn).

That’s interesting. I modeled some yesterday morning. Had me contemplating hardeing my house. Wondered about heat flux rate and burning wood...

Height matters because the radii are showing ground effects, and so it is a slant range. (Similar to this: http://blog.nuclearsecrecy.com/wp-content/uploads/2013/12/Hiroshima-detonation-500-rem-radius-slant-range.jpg …)
