CNT Parameterization Based on the Observed INP Concentration during Arctic Summer Campaigns in a Marine Environment
Aerosol–cloud interactions present a large source of uncertainties in atmospheric and climate models. One of the main challenges to simulate ice clouds is to reproduce the right ice nucleating particle concentration. In this study, we derive a parameterization for immersion freezing according to the...

Aerosol–cloud interactions present a large source of uncertainties in atmospheric and climate models.
