Ice nucleation by kaolinite: Morphology shapes the size dependence of ice nucleation active sites on dust particles

Mineral dusts are the most important type of ice-nucleating particles and play a key role in cloud formation and climate. Their activity is commonly assumed to scale with particle surface area, yet whether this assumption holds across particle sizes remains unverified. Here, we q...

Summertime ice-nucleating particle concentrations over the Eurasian-Arctic Seas

Abstract. Ice nucleating particles (INPs) catalyze primary ice formation in Arctic low-level mixed-phase clouds, influencing their persistence and radiative properties. Knowledge of the abundance, sources, and nature of INPs over the remote Arctic Ocean is scarce, particularly in...
