Background

Main motivation: * model intercomparison / performances for BaP, also in relation with modelling of correlated species: PM, EC, levo * reference BaP levels for exposure assessment in relation with EU target levels * Link BaP with PAHs in general in relation with Gothenburg Protocol Review * Sensitivity to modelled processes

Modelling experiment

Annual simulation encompassing IMP field campaing in the winter of 2017/2018 Referred to as Experiment “E” of Eurodelta-Carb PM modelling phase, with adaptation in the model technical specifications below
