The Schauinsland Ozone Precursor Experiment: SLOPE Invited contribution to subproject LOOP Andreas Volz-Thomas and the SLOPE Science Team ** Institutfur Chemie und Dynamik der Geosphare II, Forschungszentrum Julich, D-52425 Julich, Germany Abstract The Schauinsland Ozone Precursor Experiment (SLOPE) was conducted in September 1992 and June 1996 as part of the former EUROTRAC subproject TOR (Tropospheric Ozone Research) in order to study the photochemical formation of ozone and the degradation of the precursors in the plume of the city of Freiburg on its way to Schauinsland. Details of the 1996 experiment are also discussed in Kalthoff et al, see volume 2; and Kolahgar et a/., this volume. During both campaigns, unexpectedly large OH-radical concentrations were derived from the hydrocarbon decay in view of the high NO% concentrations in the Freiburg plume. The results indicate the potential for th
