Ice-nucleating particle concentration measurements from Ny-Ålesund during the Arctic spring–summer in 2018
In this study, we present atmospheric ice-nucleating particle (INP) concentrations from the Gruvebadet (GVB) observatory in Ny-Ålesund (Svalbard). All aerosol particle sampling activities were conducted in April–August 2018. Ambient INP concentrations ( n INP) were measured for aerosol particles col...
