The altocumulus layers developed in aged Saharan dust layers between 3.5 km (-20 C) and 7.5 km height (-35 C cloud top temperature). We observed such altocumulus developments on 12 days. By applying our recently developed polarization-lidar method we estimated the ice-nucleating particle concentration (INPC, immersion freezing) at cloud level (before the clouds developed and after their dissolution). Simultaneously performed Doppler lidar observations of the terminal … | Description: | test | URI: | https://hdl.handle.net/20.500.14279/29442 | Type: | Conference Papers | Affiliation : | Leibniz Institute for Tropospheric Research Cyprus University of Technology The Cyprus Institute, Energy, Environment and Water Research Centre |
