[QUOTE="casualguitar, post: 6894036, member: 695787"] Hi Chet, looking further into the CO2 desublimation rate function, these are plots of temperature versus sublimation pressure (the gas-solid curve), and then temperature versus desublimation rate for a range of ##k_i## values, and ##y_{CO2}## = 0.2 (as it is in Tuinier et al). Note that for the sublimation pressure curve, for temperature values above the triple point temperature (216K), i've used the liquid-vapour curve. Is there an alternative here? We could possibly say: if T is less than the triple point temperature, use the sublimation pressure curve, if T is greater than the triple point temeprature, let sublimation pressure = some large number?
