Ice supersaturations exceeding 100% at the cold tropical tropopause: implications for cirrus formation and dehydration

Recent in situ measurements at tropical tropopause temperatures as low as 187 K indicate supersaturations with respect to ice exceeding 100% with little or no ice present. In contrast, models used to simulate cloud formation near the tropopause assume a supersaturation threshold for ice nucleation o...
