Short summary
Recent research has analyzed the formation of a particle (CN) layer in the stratosphere above Antarctica after sunrise. We investigate the CN layer formation processes with our particle formation model and derive sulfuric acid profiles (no measurements exist). Our study confirms existing explanations and gives more insights into the formation process, leading to higher derived concentrations. Therefore, this paper improves our understanding of the processes in the high atmosphere.
