PM2.5-bound biogenic secondary organic aerosol tracers over a regionally representative site in central India: Characteristics and sources

Chemical Characteristics and Source Apportionment of Biogenic Primary and Secondary Organic Aerosols in an Alpine Ecosystem of Tibetan Plateau

“…However, the total BSOA concentration in Mt. Gongga was lower than those in a forest site of Sapporo (35.4 ng/m 3 ), nine sites in Guangdong (73.9 ng/m 3 ), and central India (116 ng/m 3 ) (Haque et al., 2023; Nirmalkar et al., 2023; Zhang et al., 2019). The seasonal variation of total BSOA concentration followed the order of winter (39.4 ± 18.5 ng/m 3 ) > summer (33.6 ± 14.5 ng/m 3 ) > autumn (27.6 ± 15.8 ng/m 3 ) > spring (25.3 ± 10.4 ng/m 3 ).…”
