During three flight campaigns: around the world (2012, 2016) and over the Arctic (2013) we demonstrated the feasibility of scientific research and aerial measurements of aerosolized black carbon (BC) with ultra-light aircraft. Measurements provided first ever information on BC concentrations and sources over such a large area at altitude. These data and especially the vertical distribution of BC are a crucial requirement for our understanding of the dispersion of pollutant species of anthropogenic origin, and their possible effects on radiative forcing, cloud condensation, and other phenomena which can contribute to adverse outcomes. Light absorbing carbonaceous aerosols and BC in particular are a unique tracer for combustion emissions, and can be detected rapidly and with great sensitivity by filter-based optical methods.
