Short summary

The coupled system of the Manchester Aerosol Chamber and Manchester Ice Cloud Chamber was used to study the ice-forming abilities of secondary organic aerosol particles under mixed-phase cloud conditions. Given the vast abundance of secondary organic particles in the atmosphere, they might present an important contribution to ice-nucleating particles. However, we find that in the studied temperature range (20 to 28 °C) the secondary organic particles do not nucleate ice particles.
