Short summary
In this study the freezing behavior of ash particles immersed in supercooled cloud droplets was investigated. It was found that ash from coal burning initiates freezing well above the limit for homogeneous ice nucleation and may contribute to cloud glaciation and precipitation formation on a regional scale. Furthermore, the experimental results were influenced by a change in sample preparation and/or particle generation which must be accounted for when comparing to previous studies.
