Rime splintering significantly boosts ice crystal number concentration in Arctic mixed-phase clouds.
Simulations required a tenfold increase in splinter production to match observed ice crystal counts during ACLOUD.
Secondary ice production became self-sustaining in simulations, independent of initial freezing from ice-nucleating particles.
Model sensitivity tests indicated that ice production efficiency varies greatly with parametrizations and temperature.
