What is the significance of the evaporation coefficient ($ extalpha_e$) in ice sublimation science?

Answer

It corrects the theoretical sublimation rate to match the experimentally observed rate.

The evaporation coefficient ($ extalpha_e$) is a factor introduced to reconcile the theoretical sublimation rate, derived from simple kinetic gas theory, with the rate actually measured during vacuum experiments.
