Short summary
It is important to study ice-nucleating particles in the environment to learn more about cloud formation. We studied the composition of ice particle residuals and total aerosol particles sampled in parallel during mixed-phase cloud events at Jungfraujoch and discovered that soot and complex secondary particles were not present. In contrast, silica, aluminosilicates, and other aluminosilicates were the most important ice particle residual groups at site temperatures between −11 and −18 °C.
