      abstract     = {Atmospheric aerosol plays an ambivalent role for mankind.
                      On the one hand, aerosol is known to have adverse health
                      effects and even increase mortality. On the other hand, a
                      raised aerosol concentration in the atmosphere is the only
                      anthropogenic contribution to the Earth’s climate known to
                      have a net cooling effect by scattering light and acting as
                      cloud condensation nuclei (CCN). Among other things, the
                      magnitude of these effects depend on the chemical
                      composition of the aerosol. In this work, an Aerosol Mass
                      Spectrometer (AMS) was adapted for airborne aerosol chemical
                      composition measurements on a Zeppelin NT airship. The
                      Zeppelinplatform allows for measurements with high spatial
                      resolution throughout the entire planetary boundary layer
                      (PBL). The new instrument was successfully operated aboard
                      the Zeppelin NT on nine out of ten flight days of a seven
                      week campaign in two countries in the context of the
                      European project PEGASOS. The mass concentrations of the
                      measured aerosol chemical species are presented for these
                      days.The campaign observations revealed a higher relative
                      concentration of nitrate aerosol in the Netherlands compared
                      to the Po Valley in northern Italy. For sulfate aerosol, the
                      situation was opposite. Furthermore, the organic aerosol was
                      more aged in the Po Valley than in the Netherlands. The
                      influence of the aerosol chemical composition on the cloud
                      droplet activation was studied by computation of the
                      critical activation diameter and comparing to aerosol number
                      size distribution measurements. In some situations, the
                      chemical composition was the driving force behind changes in
                      CCN concentration, in other situations its effect was
                      overshadowed by changes in the size distribution.
                      Differences between the individual layers of the PBL were
                      identified in the mass concentrations of the aerosol
                      chemical species and the organic aerosol age. A backward
                      trajectory analysis was used in conjunction with the
                      obtained data to estimate the aerosol production rate of the
                      Po Valley to 0.60 ($\mu$g/m$^{3}$)/h for organic aerosol,
                      0.88 ($\mu$g/m$^{3}$)/h for nitrate aerosol, and 0.15
                      ($\mu$g/m$^{3}$)/h for sulfate aerosol.The aerosol ion
                      balance was used to gain insights into organic aerosol
                      functionalization patterns.},
