Short summary

Ambient particle populations and associated ice-nucleating particles (INPs) were examined from particle samples collected on board aircraft in the marine boundary layer and free troposphere in the eastern North Atlantic during summer and winter. Chemical imaging shows distinct differences in the particle populations seasonally and with sampling altitudes, which are reflected in the INP types. Freezing parameterizations are derived for implementation in cloud-resolving and climate models.
