MAX-DOAS and CE-DOAS Measurements on RV Sonne during the SHIVA campaign — •Johannes Lampel1, Martin Horbanski1, Denis Pöhler1, Enno Peters2, Folkard Wittrock2, Udo Frieß1, and Ulrich Platt1 — 1Institut für Umweltphysik, Universität Heidelberg — 2Institut für Umweltphysik, Universität Bremen
During the SHIVA campaign (Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere) on RV Sonne along the coast of Borneo in November 2011 two MAX-DOAS instruments from IUP Heidelberg and Bremen and additionally a CE-DOAS System to measure iodine monoxide mixing ratios were operated. First results from these instruments and a comparison, if applicable, will be shown. Reactive bromine and iodine compounds emitted from the ocean in the atmosphere can be of great importance for the chemical balance of the marine boundary layer, even if they are present, if at all, in very small amounts of only some parts per trillion. Furthermore they might be transported to the stratosphere due to convection. Their impact ranges from the destruction of ozone and the modification of the oxidative capacity to possible creation of cloud condensing nuclei.
