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
