Short summary
Speciation of organic aerosol was performed in the westerlies and in the Saharan Air Layer, where biogenic secondary organic aerosol (oxidation of isoprene and alpha-pinene) and primary combustion compounds (hopanes and PAHs) were observed. In the Saharan Air Layer, species (saccharides) linked to soil emission – plant tissues and microorganisms – in the inner Sahara were also identified, whereas in the westerlies biomass burning compounds (e.g. levoglucosan) from North America also occurred.
