Short summary
First- and higher order -generation products formed from the oxidation of isoprene and methacrolein with OH radicals in the presence of NOx have been studied in a simulation chamber. Differences in light source are proposed to partially explain the discrepancies observed between different studies in the literature for both isoprene- and methacrolein-SOA mass yields. According to our results, these SOA yields in the atmosphere could be lower than suggested by most of the current chamber studies.
