The study provides the first in-situ observation of secondary ice production at temperatures as low as -27°C. These observations are unique and important. I recommend to accept the paper with minor revisions.
Minor comments are:
Please discuss the possible role of the freezing of drops, which concentration is several orders higher than that of ice crystals, in production of cloud ice. It would be reasonable to refer in this context the study by Khain et al. (2022), in which A. Korolev is a co-author.
Can you compare the rates of immersion drop freezing and the rates of the mechanisms of primary ice nucleation mentioned in the paper?
