Short summary

Hydrogen peroxide is a key contributor to the oxidative chemistry of the atmosphere through its link to the most prominent oxidants controlling its self-cleansing capacity, HO_x. During the CAFE-Africa campaign, H₂O₂ was measured over the Atlantic Ocean and western Africa in August/September 2018. The study gives an overview of the distribution of H₂O₂ in the upper tropical troposphere and investigates the impact of convective processes in the Intertropical Convergence Zone on the budget of H₂O₂.
