Interactive comment on “Repeatability and randomness in heterogeneous freezing nucleation” by G. Vali

Data included in the paper under discussion were obtained with two slightly different soil suspensions and with a distilled water sample. Key results are consistent for all three samples even though they contained materials of various chemical composition and physical state. This fact raises the possibility, but with a question mark, that the concepts arrived at in the paper are perhaps applicable to most ice nuclei, independent of composition. The purpose of this short note is to reinforce that expectation by extending the list of materials for which experiments have yielded similar results. The experiments with these samples were conducted essentially the same way as that described in the paper but had different primary goals and therefore only statistical data are available not the individual drop histories. Consequently, these data could not be
