Hydrogen Peroxide Concentration Variations in Marine Tropospheric Atmosphere

  • P. Jacob
  • D. Klockow

Summary

Hydrogen peroxide, one of the key compounds in multiphase atmospheric chemistry, was measured on an Atlantic cruise of the German research vessel “Polarstern”, in rain, seawater and ambient air by a chemiluminescence technique, gas phase H2O2 after cryogenic sampling.

The presented results show an increase of gas phase mixing ratios of about 45 pptv per egree latitue between 50°N and 0°, and a maximum of 3.5 ppbv around the equator. Generally higher mixing ratios were observed in the southern hemisphere, with a clear diurnal variation.

Correlations with meteorological parameters and concentrations of other atmospheric trace gases are given, as well as comparisons with model calculations.
