摘要：

Measurements of H2O2 and related species were made by aircraft on 18 flights over 11 days during June 1987 over Ohio. Measurements focussed on conditions conducive to the formation of convective storms. Concentrations of H2O2 ranged from <0.2 to 7ppb and exhibited as much as a factor of 10 variability even on a given day at fixed altitude, as well as between days. Hydrogen peroxide concentration typically was low near the surface, rose to a maximum near the top of the boundary layer, then slowly decreased with altitude. In contrast, SO2 and NOy were largely confined to the surface layer. Comparison of the profile shapes of H2O2 and SO2 suggest that mixing processes will have a large influence on the extent to which these two species will react in convective systems. -from Authors
