Offline INP measurements at Ny-Ålesund (Svalbard) in 2018

This dataset reports atmospheric ice nucleating particle (INP) concentrations, measured offline on samples collected at ground level in Ny-Ålesund (Svalbard; 78°55’ N, 11°56’ E), in spring and summer 2018. The ice nucleation properties of the samples were characterized by means of two offline instruments: the Dynamic Filter Processing Chamber (DFPC), detecting condensation freezing INPs, and the West Texas Cryogenic Refrigerator Applied to Freezing Test system (WT-CRAFT), measuring INPs by immersion freezing. Sampling for DFPC occurred on a campaign basis (one in spring and one in summer) with daily resolution and sampling time of about four hours, while filters for WT-CRAFT were collected continuously from April to August, with four days sampling intervals. Meteorological data from 15 April to 15 August 2018 are also reported. Meteorological parameters were taken from the Amundsen-Nobile Climate Change Tower, positioned less than 1 Km N-E of the sampling point. This dataset is discussed in a manuscript titled “Condensation and immersion freezing Ice Nucleating Particle measurements at Ny-Ålesund (Svalbard) during 2018: evidence of multiple source contribution” by M. Rinaldi et al., which is currently under review for Atmospheric Chemistry and Physics
