Present and retrospective state of organic versus inorganic aerosol over europe : implication for climate

Objective

The project attempts to quantify the radiative impact of organic/inorganic aerosol in Europe since ~ AD 1850. Present-day aerosol composition is investigated at remote sites on a west-east transect including precipitation samples. Apart from inorganic species, specific analyses comprise elemental, particulate and secondary carbon fractions as well as organic tracers including 14C for fossil/biomass differentiation. The change of organic/inorganic aerosol load over Europe since the pre-industrial era will there be reconstructed from available Alpine ice cores via experimental air/snow relationship at the glacier sites. Model simulations and observed organic aerosol distributions are iteratively used to estimate natural versus anthropogenic (primary/secondary) source contributions at present and past. From that, past trends in radiative aerosol forcing due to change in load and composition are quantified with regional model simulations.
