Heterogeneous Ice Nucleation by Soufriere Hills Volcanic Ash Immersed in Water Droplets
Fig 2
Values of ns in units of cm-2 as a function of temperature, at concentrations of 0.01-0.1 wt%, for droplets of nanolitre and microlitre volume containing Soufriere Hills volcanic ash.
Parameterisations of K-feldspar taken from Atkinson et al. [31] and desert dusts taken from Niemand et al. [36] are included for comparison.
