...The aforementioned values are well within the range of previously reported PM1 values (100–530μg/m 3) from filter studies and AMS measurements at the same location [Tare et al., 2006; Gupta and Mandariya, 2013; Singh et al., 2014; Bhattu and Tripathi, 2015]....

...The size distribution of the organics was broader than that of the other species and extended to smaller sizes, as reported in another AMS study from this location [Bhattu and Tripathi, 2015]....

...…better closure results obtained are unexpected because atmospheric processes, such as coagulation, gas condensation, and photochemical transformation, will shift these aerosols to an internally mixed state [Moore et al., 2011; De Gouw and Jimenez, 2009; Jimenez et al., 2009; Shamjad et al., 2012]....

...Even after considerable efforts, the dependence of aerosol hygroscopicity on the degree of oxygenation under subsaturated and supersaturated conditions is not well understood [Jimenez et al., 2009; Chang et al., 2010; Juranyi et al., 2009]....
