      abstract     = {During the Berlin Ozone Experiment BERLIOZ in July-August
                      1998 quasi-continuous measurements of C-2-C-12 nonmethane
                      hydrocarbons (NMHCs) were carried out at 10 sites in and
                      around the city of Berlin using on-line gas-chromatographic
                      systems (GCs) with a temporal resolution of 20-120 minutes.
                      Additional airborne NMHC measurements were made using
                      canister sampling on three aircraft and an on-line GC system
                      on a fourth aircraft. The ground based data are analyzed to
                      characterize the different sites and to identify the
                      influence of emissions from Berlin on its surroundings.
                      Benzene mixing ratios at the 4 rural sites were rather low
                      (<0.5 ppbv). Berlin (and the surrounding highway ring) was
                      identified as the main source of anthropogenic NMHCs at
                      Eichstadt and Blossin, whilst other sources were important
                      at the furthermost site Menz. The median toluene/benzene
                      concentration ratio in Berlin was 2.3 ppbv/ppbv, agreeing
                      well with measurements in other German cities. As expected,
                      the ratios at the background sites decreased with increasing
                      distance to Berlin and were usually around one or below. On
                      20 and 21 July, the three northwesterly sites were situated
                      downwind of Berlin and thus were influenced by its
                      emissions. Considering the distance between the sites and
                      the windspeed, the city plume was observed at reasonable
                      time scales, showing decreasing toluene/benzene ratios of
                      2.3, 1.6 and 1.3 with increasing distance from Berlin.
                      Isoprene was the only biogenic NMHC measured at BERLIOZ. It
                      was the most abundant compound at the background sites on
                      the hotter days, dominating the local NMHC reactivity with
                      averaged contributions to the total OH loss rate of $51\%$
                      and $70\%$ at Pabstthum and Blossin, respectively. Emission
                      ratios (relative to CO and to the sum of analysed NMHCs)
                      were derived from airborne measurements. The comparison with
                      an emission inventory suggests traffic-related emissions to
                      be the predominating source of the considered hydrocarbon
                      species. Problems were identified with the emission
                      inventory for propane, ethene and pentanes.},
