The range of aerosol yield results from several different experiments with higher yields observed from higher initial alpha-pinene concentrations. dFrom nine different experiments. Average of reported range of temperatures. eAerosol yields are reported as the maximum carbon yield (19 - 27%). To convert to total SOA mass yield for comparison with other experiments, we assumed the aerosol was 60% carbon. fPercent molar yield of identified carboxylic acids and carbonyls in the aerosol phase. gSOA yields are expressed on a percent mass basis, using the ratio of mug organic aerosol m-3 to mug parent terpene m-3, assuming an aerosol density of 1.25 g cm-3.
