Predicting global atmospheric ice nuclei distributions and their impacts on climate
Knowledge of cloud and precipitation formation processes remains incomplete, yet global precipitation is predominantly produced by clouds containing the ice phase. Ice first forms in clouds warmerExpand

The susceptibility of ice formation in upper tropospheric clouds to insoluble aerosol components
Ice may form by both homogeneous and heterogeneous freezing nucleation processes in clouds at temperatures below -35°C. Most investigations have focused on the former process. This paper presentsExpand

Water droplet calibration of the Cloud Droplet Probe (CDP) and in-flight performance in liquid, ice and mixed-phase clouds during ARCPAC
Abstract. Laboratory calibrations of the Cloud Droplet Probe (CDP) sample area and droplet sizing are performed using water droplets of known size, generated at a known rate. Although calibrationsExpand
