Notes. (a) Cooling dominated by radiation from the start. Ecool is the total released thermal energy of the grain, with the proportion of energy radiated away as photons Erad given as the percentage of Ecool. Tswitch and tswitch are the temperature and time for switching from evaporative to radiative cooling. The last column gives the final ice thickness after the grain has cooled.
