Abstrakt: Atmospheric aerosols (AA) harm human health (e.g., Liu et al. 2019) and affect the climate through cloud formation and radiation forcing (Mahowald 2011). Their effect on climate is still associated with large uncertainties within climate modeling (IPCC 2021). The assessment of aerosol global effects is usually done through ground-based measurement in rural areas to avoid local pollution sources. However, the changes in the planetary boundary layer (PBL) and the high population density of Europe limit the representativeness of those measurements. Higher elevation measurements and vertical profiles of atmospheric pollutants and meteorological quantities are needed to assess the spatial representativeness of those ground-based measurements and distinguish local from long-range transported aerosols. The wide range of aerosol particle size and the variety of chemical components make it difficult to predict their impact on the state of the PBL, the atmospheric transport, and the radiative forcing in the upper and lower troposphere (Schwarz et al. 2016, Ramanathan et al. 2002). Solar radiation changes due to the presence of aerosols and can provoke greater ozone production and high aerosol concentrations and influence cloud condensation and ice nuclei (Tao et al. 2014, Liu et al. 2021). Thus, it is crucial to measure aerosols bothinside and above the PBL together with vertical detailed characterizations of meteorological parameters. Few tall towers enable online aerosol studies (Bosveld et al. 2020), and most of the existing ones are located in cities. Therefore, this study allows operating measurements that have not been done yet and promises valuable results to reduce uncertainty induced by aerosols.
