Diverse sources and aging change the mixing state and ice nucleation properties of aerosol particles over the western Pacific and Southern Ocean

Atmospheric Chemistry and Physics has published an article by Xue et Al which presents “micro-spectroscopic characterizations and ice nucleation properties of particles collected during a cruise from South Korea to Antarctica in 2019”. The abstract concludes: “our analysis shows that assuming an internally mixed particle population in the marine atmosphere can lead to errors of several orders of magnitude in predicting ice nucleation rates.”

The aerosol particles were collected on board the RV Araon – a large icebreaker operated by the Government of South Korea. Some samples were collected on Silson’s silicon nitride coated chips for ice nucleation experiments.
