2,000 water droplets with soot particles immersed are monitored individually to establish the link between physico-chemical properties and freezing efficiency. Soot behaviour in water (relating with number density and agglomerate size), wetting, and water soluble fraction (WSF) are found as key parameters defining the freezing temperature. The maximum freezing efficiency, 6°C, is reported for homogeneously distributed low size soot agglomerates of low number density and with hydrophilic coverage.
Keywords Heterogeneous freezing, soot aerosols, wetting, hydration
