| contents | Number concentration of ice nucleating particles N(INP) in the Arctic were derived from filter samples collected at Villum Research Station (VRS, Northern Greenland) during the course of two years, from July 2018 to September 2020. Each filter aimed at sampling for 3.5 days, and in total, 181 samples were retrieved for this study. Filter analysis was done with two well proven INP analysis techniques, ultimately resulting in a spectrum of N(INP) for each filter. We also included a heat treatment of the samples (1 hour at 90°C, or at 85°C for a few exceptions, due to instrumental issues). With this, one can determine the fraction of proteinaceous INP, which are of biological origin. For each filter sample, we here provide the temperature dependent measured frozen fractions (f_ice) of each filter from both instruments LINA (Leipzig Ice Nucleation Array) and INDA (Ice Nucleation Droplet Array) included in separate files (e.g. INDA2_20180716_1 for INDA; LINA_20190923_1 for LINA). Most filters underwent thermal treatment and therefore the f_ice of the treated samples is also provided in separate files (e.g. INDA2_20200622_heated_90_1h_1). For each filter sample, values of N(INP) spectra from LINA and INDA were interpolated to values at 0.1K intervals, and then the two spectra were merged. Details on this procedure can be found in Sze et al. (2023). The here presented data include all datasets (f_ice over the measured temperature range) for all samples, separately for all measurements (i.e., LINA, INDA and thermally treated INDA). A list of all these separate datasets is given, together with some details related to the sample (see the table of parameters below). Each of the datasets is separately available. For more details on the separate samples and for concentration data (given as merged spectra), refer to the related data (doi:10.1594/PANGAEA.953838). |
