As already noted in the introductory sections, AIDA ice nucleation studies primarily focus on a precise determination of the critical ice saturation ratio for relevant aerosol types like H2SO4/H2O solution droplets, mineral dust and soot particles, as well as internally mixed aerosol particles. The ice saturation ratio Sice(T)... [Pg.77]

The onset of HNO3 uptake into H2SO4/H2O solutions was first inferred from vapor pressure measurements by Molina and coworkers . These authors concluded that under very cold stratospheric conditions the solution droplets would take up H2O and HNO3 and then freeze. However, laboratory freezing experiments by Koop et al showed that even bulk samples of such solutions can be brought to extremely low temperatures without freezing. [Pg.148]
