摘 要:
We report on importance of conducting comprehensive studies of atmospheric aerosol particles, which cannot bedone if information from various complementary sensors is unavailable. We present an example for suchapplication and recommend on the types of sensors that should be used in view of the ACTRIS and RI-URBANSnew strategies for monitoring at supersites. Although active and passive remote sensing data was not available incontinuous mode, we show that synergic use of them with in-situ observations allows for comprehensive study oftemporal and height-resolved distribution of aerosol in the lower troposphere and it can be successfully combinedto assess biomass burning impact on air quality and optical properties.The analysed period was divided into three episodes based on the measured black carbon (BC) concentrationand the prevailing wind direction. The dominant 72-h backward trajectories were ending in western Europe, mid-Atlantic and western Russia, respectively, The in-situ measured mass concentrations of BCtotal and BCapportioned to biomass burning as well as particulate matter (PM) concentrations in accumulation mode weretwice higher during the first and last episodes compared to the second episode, representing long-range transportfrom different source regions. The obtained complementary surface, column-integrated, and layer-derived sizedistributions and other parameters demonstrate the added value of multisensor analyses.
