  abstract = {{A} growing number of studies are using specific primary sugar species, such as sugar alcohols or primary saccharides, as marker compounds to characterize and apportion primary biogenic organic aerosols ({PBOA}s) in the atmosphere. {T}o better understand their annual cycles, as well as their spatiotemporal abundance in terms of concentrations and sources, we conducted a large study focusing on three major atmospheric primary sugar compounds (i.e., arabitol, mannitol, and glucose) measured in various environmental conditions for about 5300 filter samples collected at 28 sites in {F}rance. {O}ur results show significant atmospheric concentrations of polyols (defined here as the sum of arabitol and mannitol) and glucose at each sampling location, highlighting their ubiquity. {R}esults also confirm that polyols and glucose are mainly associated with the coarse rather than the fine aerosol mode. {A}t nearly all sites, atmospheric concentrations of polyols and glucose display a well-marked seasonal pattern, with maximum concentrations from late spring to early autumn, followed by an abrupt decrease in late autumn, and a minimum concentration during wintertime. {S}uch seasonal patterns support biogenic emissions associated with higher biological metabolic activities (sporulation, growth, etc.) during warmer periods. {R}esults from a previous comprehensive study using positive matrix factorization ({PMF}) based on an extended aerosol chemical composition dataset of up to 130 species for 16 of the same sample series have also been used in the present work. {T}he polyols-to-{PMPBOA} ratio is 0.024 +/- 0.010 on average for all sites, with no clear distinction between traffic, urban, or rural typology. {O}verall, even if the exact origin of the {PBOA} source is still under investigation, it appears to be an important source of particulate matter ({PM}), especially during summertime. {R}esults also show that {PBOA}s are significant sources of total organic matter ({OM}) in {PM}10 (13 +/- 4% on a yearly average, and up to 40% in some environments in summer) at most of the investigated sites. {T}he mean {PBOA} chemical profile is clearly dominated by contribution from {OM} (78 +/- 9% of the mass of the {PBOA} {PMF} on average), and only a minor contribution from the dust class (3 +/- 4 %), suggesting that ambient polyols are most likely associated with biological particle emissions (e.g., active spore discharge) rather than soil dust resuspension.},
