Short summary

Optical properties of polar and non-polar extracts of biomass burning organic aerosols (BBOAs) generated by burning of globally and regionally important fuels were studied. The non-polar fraction of BBOAs was found to be more light absorbing than the polar fraction. Laboratory aging of BBOAs produced by flaming fuels increased aerosol light absorption attributed to the formation of organo-nitrogen compounds. Refractive indices were retrieved for both polar and non-polar extracts of BBOAs.
