Abstract
Balloon observation of stratospheric aerosols was carried out at Tsuku ba, Japan, on 24 August 1993, about two years after the Pinatubo volca nic eruption. Stratospheric aerosol particles collected from the strat ospheric aerosol layer using an impactor were analyzed by an analytica l electron microscope. Crustal particles were not detected in all size ranges. The results indicated that most of the particles observed ove r Tsukuba were aqueous H2SO4 droplets without a solid nucleus. This su ggests that these particles were formed through homogeneous nucleation processes.
