Short summary
The novelty of the paper is to combine a large set of measurements and meteorological models to study the genesis of thick cloud and diamond dust/ice fog (ice crystals) episodes above Dome C, Antarctica. The originality of the work is to attribute the presence of thick cloud and diamond dust/ice fog to advection and microphysical processes with oceanic and continental origin of air masses, respectively. Thick cloud episodes are reproduced by the models but not diamond dust/ice fog episode.
