Short summary
This paper describes a newly designed cold electrodynamic balance (EDB) which can be used to study the evaporation kinetics and freezing properties of aerosols at temperatures down to -40˚C. The abilities of the new EDB are exemplified through the study of the immersion freezing properties of water droplets containing extracts of water birch pollen (Betula fontinalis occidentalis). Protein-rich pollen extracts are found to be significantly more ice-active than non-proteinaceous extracts.
