CONTENTS ----------- File listing handling_blank.csv: Contains the temperature binned data from all the handling blanks used in this paper. unheated.zip: Contains the temperature binned, size resolved ice-nucleating activity data for Copper River valley dusts. heated.zip: Contains the temperature binned, size resolved ice-nucleating activity data for Copper River valley dusts where heat was applied to test for the presence of biological ice nucleating entities. Notes: 1. File names and column headers contain dates corresponding to the sample collection in the form YYMMDD. 2. Headers in the data files correspond to variables in the corresponding paper (Barr et al., 2023) as follows: ff = f_ice, kt = k(T), Kt = K(T), inp = N_INP (per litre), ns = n_s (per cm^2) 5. METHODS ---------- Refer to the associated paper for a full description of the methods (Barr et al., 2023).
