In this study, the microphysical sensitivity of Arctic mixed-phase multilayer clouds are examined via two case studies observed during the MOSAiC campaign in September 2020. Sensitivity simulations on cloud droplet activation, primary ice, and secondary ice processes were performed. The ICON model is used to model these clouds and observational data from the MOSAiC campaign is used to constrain and evaluate the model.

All data has been postprocessed and only contains the mean values over a smaller region ~15km surrounding the ship. Files follow the format <GRID>_<DATE>_<comment>.nc Please see Table 1 in the paper for the description of the simulations performed. Each 2-moment run has accumulated process rates associated with the simulation named <GRID>_<DATE>_<comment>_process_rates.nc. en 10.5194/egusphere-2024-2988 Bundesministerium für Bildung und Forschung 501100002347 03F0891B 8,2 MB application/x-tar
