Ice nucleating particle concentrations at Macquarie Island, 2017/8
These data list ice nucleating particle (INP) number concentrations active in the immersion freezing mode. Aerosol filters were collected during late March 2017 to March 2018 as part of the Macquarie Island Cloud and Radiation Experiment (MICRE), located at the Australian Antarctic Division's M...
