Abstract: Global anthropogenic emissions from the EDGAR-HTAPv3 and CAMS are helpful information as an input to air quality photochemistry models with good simulation results compared to observations if all sectors are considered. However, emission values belonging to industrial and road transport sectors should be more consistent with previous local studies about source apportionment and experimental tunnel campaigns. This is because experimental campaigns and source apportionment results have proved the road transport sector is the main source of contribution to the local air quality of the Metropolitan Area of São Paulo. This study aims to refine EDGAR-HTAPv3’s emissions for the industrial and road transport sectors by considering previous studies related to and assimilated into the LAPAt model as long as the calculation of dust-paved road resuspension. The refining emissions will be evaluated with an air quality photochemistry model (e.g., WRF-Chem or WRF-CMAQ), and their fine particulate matter simulations will also be compared to observations. Although road transport emissions for São Paulo have been reducing since 1980, some secondary pollutants such as ozone and fine particles remained steady. Therefore, anthropogenic emission corrections are essential to evaluate future environmental scenarios in which sources by sectors must be analyzed to establish plans of emission controls on the road transport sector of São Paulo.
