In situ measurements of stratospheric H2SO4- and HSO3-vapors using passive chemical ionization mass spectrometry were made in October 1982 after the eruption of volcano El Chichon. Data were obtained between about 20 and 41 km showing [H2SO4 + HSO3] sum concentrations between about 104 and 2 × 105 cm-3 below 29 km and a steep rise above this altitude. Maximum [H2SO4 + HSO3] values of about 3 × 106 cm-3 are reached above 35 km.
Partial [HSO3] concentrations increase above 34 km reaching about 4 × 105 cm -3 around 40 km. From the measurements it is concluded that H2SO4- and probably HSO3-photolysis have an important influence above 34 km leading to the observed increase of [HSO3] and a depletion of H2SO4-vapor.
It also seems that the data support the view of heterogeneous HSO3 removal. If correct, this would imply that stratospheric aerosols are formed primarily from HSO3- rather than H2SO4-vapor.
