Short summary

We investigated the importance of mineral dust, sea spray aerosol, and anthropogenic aerosol to the ice-nucleating particle (INP) population in the Canadian Arctic during spring 2016. The results suggest that mineral dust transported from the Gobi Desert was a major source of the INP population studied, and that sea spray aerosol decreased the ice-nucleating ability of mineral dust. The results should be useful for testing and improving models used to predict INPs and climate in the Arctic.
