Chemical composition of particulate matter (PM) contains a large proportion of organic aerosols (OA), but its molecular speciation remains unresolved (Liang et al., 2017). OA associated with anthropogenic and secondary sources are extensively studied, while the contributions from primary biogenic aerosols (PBOA) remain poorly documented. Primary sugar compounds (SC, i.e. polyols and monosaccharides) are ubiquitous water-soluble class of OA, and have been widely proposed as reliable tracers to characterize and apportion PBOA sources (Bauer et al., 2008). However, quantitative data on SC annual, spatial and seasonal distributions are still limited. Furthermore, the characterization of sources and the quantification of PBOA mass associated with these SC’s remain elusive. Here, we provide a large overview of PBOA contribution to the total OM mass in France, as well their major components...
