Short summary
Delhi, India, is the most polluted megacity on the planet, posing acute challenges to public health. We report on source apportionment conducted on 15 months of highly time-resolved mass spectrometer data. We find that severe air pollution episodes are dominated by primary organic aerosol, while secondary organic aerosol dominates the fractional contributions year-round, suggesting the importance of sources as well as their atmospheric processing on pollution levels in Delhi.
