Continuous measurements ofH202and organic hydroperoxides were performed at the field station Schauinsland between January 1989 and June 1991 using an ezyme catalysed fluorescence instrument. The mixing ratios were in the range of the detection limit (20 ppt) up to 4.4 ppb for ~Oz and 1.7 ppb for ROOR. Both Hz02 and ROOH show a strong seasonal variation with maximum concentrations in summer. The observed seasonal trend is in line with the photochemical formation mechanism on the one hand and the main atmospheric loss processes on the other hand. The mixing ratios ofHz02 and ROOH are strongly influenced by wet deposition. For interpretation ofthe behavior ofthese ...
