      abstract     = {In this work we present airborne in situ trace gas
                      observations of hydrogen peroxide (H2O2) and the sum of
                      organic hydroperoxides over Europe during the Chemistry of
                      the Atmosphere – Field Experiments in Europe (CAFE-EU,
                      also known as BLUESKY) aircraft campaign using a wet
                      chemical monitoring system, the HYdrogen Peroxide and Higher
                      Organic Peroxide (HYPHOP) monitor. The campaign took place
                      in May–June 2020 over central and southern Europe with two
                      additional flights dedicated to the North Atlantic flight
                      corridor. Airborne measurements were performed on the High
                      Altitude and LOng-range (HALO) research operating out of
                      Oberpfaffenhofen (southern Germany). We report average
                      mixing ratios for H2O2 of 0.32 ± 0.25, 0.39 ± 0.23
                      and 0.38 ± 0.21 ppbv in the upper and middle
                      troposphere and the boundary layer over Europe,
                      respectively. Vertical profiles of measured H2O2 reveal a
                      significant decrease, in particular above the boundary
                      layer, contrary to previous observations, most likely due to
                      cloud scavenging and subsequent rainout of soluble species.
                      In general, the expected inverted C-shaped vertical trend
                      with maximum hydrogen peroxide mixing ratios at 3–7 km
                      was not found during BLUESKY. This deviates from
                      observations during previous airborne studies over Europe,
                      i.e., 1.64 ± 0.83 ppbv during the HOOVER campaign and
                      1.67 ± 0.97 ppbv during UTOPIHAN-ACT II/III.
                      Simulations with the global chemistry–transport model EMAC
                      partly reproduce the strong effect of rainout loss on the
                      vertical profile of H2O2. A sensitivity study without H2O2
                      scavenging performed using EMAC confirms the strong
                      influence of clouds and precipitation scavenging on hydrogen
                      peroxide concentrations. Differences between model
                      simulations and observations are most likely due to
                      difficulties in the simulation of wet scavenging processes
                      due to the limited model resolution.},
