Aerosol absorption profiling from the synergy of lidar and sun-photometry : The ACTRIS-2 campaigns in Germany, Greece and Cyprus

Aerosol absorption profiling is crucial for radiative transfercalculations and climate modelling. Here, we utilize the synergyof lidar with sun-photometermeasurements to derive the absorption coefficient and single scattering albedoprofiles during the ACTRIS-2 campaigns held in Germany, Greece and Cyprus. The remote sensing techniques are compared with in situ measurements in order to harmonize and validate the different methodologies and reduce the absorption profiling uncertainties.
