Short summary
Online measurements of bulk aerosol organic nitrogen (ON), in conjunction with a comprehensive array of source markers, have revealed five emission sources and five potentially significant formation processes of nitrogenous organic aerosols. This study provides a first quantitative source analysis of ON aerosol and valuable observational evidence of secondary ON aerosol formation through NH3 and NOx chemistries.
