      abstract     = {[1] Meteorological and chemical measurements, including
                      peroxy radicals, made during the Berlin Ozone Experiment
                      (BERLIOZ) in summer 1998 at Pabstthum, a rural site about 50
                      km NW of the city, are described. The analytical techniques
                      and data quality are discussed, including the comparison of
                      different methods deployed side by side at Pabstthum. The
                      highest concentrations of NOx (>20 ppb) and other precursors
                      were observed on days when relatively young air was advected
                      to Pabstthum from the greater Berlin area. NOx often
                      increased during the night due to emissions from the
                      surrounding soils under stagnant conditions with a shallow
                      boundary layer as is evident in the strong negative
                      correlation between nocturnal NO mixing ratios and product
                      of ozone and wind speed. The ozone production rate (PO3)
                      calculated from the photostationary state (PSS) of NOx and
                      O-3 increased with NO and reached values of up to 90 ppb
                      h(-1). PO3 calculated from NO and the measured peroxy
                      radical concentrations was much lower, around or below 10
                      ppb h(-1). The lower production rates obtained from the
                      peroxy radical measurements are consistent with the ozone
                      budget in the city plume of Berlin. The new JPL
                      recommendation for the rate coefficient of the reaction of
                      NO with O-3 slightly improves the disagreement between PSS
                      and measured peroxy radicals. However, another enhancement
                      of $10-20\%$ in the rate coefficient would be required in
                      order to match the results within the uncertainty of the
                      measurements in the high NOx regime. Even then, PSS remains
                      to overpredict PO3 by a factor of 2 at low NOx
                      concentrations. Hence, a yet unidentified process must exist
                      in the atmosphere that converts NO to NO2 without leading to
                      a net production of ozone. The PSS results from other
                      studies are similar as at Pabstthum, suggesting that the
                      overestimation of peroxy radicals and PO3 by the PSS
                      approach is not a particular feature of the conditions at
                      the site.},
