Messungen von Peroxyradikalen in unterschiedlichen Luftgebieten

Peroxy Radicals have been measured in different regions in Europe. These different environmentsare characterized by mean or moderate anthropogenic impacts at the lower atmosphere(troposphere). Measurements were performed during the projects FIELDVOC and OCTA in 1993and 1994. The aim of these projects is an improved investigation of tropospheric ozone generation.The first measurements during both campaigns in 1993 were performed using an instrument, whichwas developed at the Max-Planck-Institut für Chmie (Mainz). For the measurements in 1994 theinstrument and the calibration method was improved for operation during field campaigns. Themeasured data are compared with results of a photochemical model to identify the role of Non-Methane-Hydrocarbons and to determine local ozone production.
