Short summary
Molecular characterization of organic aerosol in the Po Valley exhibits differences between an urban and an agricultural site, despite similar concentration of organic aerosol mass. Multivariate statistical analysis on one year of samples further reveals specific sources such as biomass burning, agricultural activities and biogenic secondary organic aerosol. Light-absorbing molecules appear to be linked to combustion, peaking at both sites during winter season.
