Abstract

Based on combined lidar-radar observations, two mixed-phase cloud cases from Limassol and Punta Arenas are studied. While the mixed-phase cloud observed over Limassol was embedded in a dust plume, the case over Punta Arenas was associated with continental and marine aerosols. Good agreement between the number concentrations of ice crystals (ICNC) and ice-nucleating particles (INPC) can be found in both cases, indicating the crucial role of INPs in ice formation. Abundant dust INPs at Limassol result in a large ICNC of 1-10 L^-1. In contrast, much lower INPC was found at Punta Arenas, contributed by continental aerosols, resulting in two orders of magnitude lower ICNC (10^-2-10^-1 L^-1).
