Abstract. The “Berlin Air quality and Ecosystem Research: Local and long-range Impact ofanthropogenic and Natural hydrocarbons” (BAERLIN2014) campaign was conductedduring the 3 summer months (June–August) of 2014. During thismeasurement campaign, both stationary and mobile measurements were undertakento address complementary aims. This paper provides an overview of thestationary measurements and results that were focused on characterization ofgaseous and particulate pollution, including source attribution, in theBerlin–Potsdam area, and quantification of the role of natural sources indetermining levels of ozone and related gaseous pollutants. Results show thatbiogenic contributions to ozone and particulate matter are substantial. Oneindicator for ozone formation, the OH reactivity, showed a 31 %(0.82  ±  0.44 s −1) and 75 % (3.7  ±  0.90 s −1) contribution from biogenic non-methane volatile organic compounds (NMVOCs) for urban background(2.6  ±  0.68 s −1) and urban park (4.9  ±  1.0 s −1) location, respectively, emphasizing the importance of such locations assources of biogenic NMVOCs in urban areas. A comparison to NMVOC measurementsmade in Berlin approximately 20 years earlier generally show lower levels today foranthropogenic NMVOCs. A substantial contribution of secondary organic andinorganic aerosol to PM10 concentrations was quantified. Inaddition to secondary aerosols, source apportionment analysis of the organiccarbon fraction identified the contribution of biogenic (plant-based)particulate matter, as well as primary contributions from vehicles, with alarger contribution from diesel compared to gasoline vehicles, as well as arelatively small contribution from wood burning, linked to measuredlevoglucosan.
