Molecular Markers of Secondary Organic Aerosol in Mumbai, India
Biogenic secondary organic aerosols (SOA) are generally considered to be more abundant in summer than in winter. Here, polar organic marker compounds in urban background aerosols from Mumbai were measured using gas chromatography-mass spectrometry. Surprisingly, we found that concentrations of bioge...

Biogenic secondary organic aerosols (SOA) are generally considered to be more abundant in summer than in winter.
