Microphysical Properties of Antarctic Polar Stratospheric Clouds and their Dependence on Tropospheric Cloud Systems
Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) and CloudSat satellite measurements are used to investigate the impact of tropospheric high and deep clouds on the microphysical properties of polar stratospheric clouds (PSCs) over Antarctica during the 2006 and 2007 winter...
