Summary
Using an aircraft preliminary investigations have been carried out into the chemical composition of clouds. Rather high concentrations of H3O+, Cl-, NO -3 , SO 2-4 , NH +4 and H2O2 were measured. Except H2O2 these components are scavenged very fast during transport over short distances over source regions. Moreover H3O+, NO -3 and SO 2-4 are likely to be formed by chemical reactions of gaseous precursors with oxidants in the liquid phase. These reactions may cause the strong decrease in high background H2O2 concentrations (ppm range).
Occasionally the chloride concentration was found to be much higher than may be expected from rain network data.
