Heterogeneity in seasonal variability of aerosol Sconc and extinction
Winter aerosol extinction was 0.1 lower than summer.
Summer UAL extinction was four times of that during winter.
Intensity of airmass updraft higher in evening over coastal WBGP unlike near-by urban location.
Higher Sconc and UAL extinction due to SB effects at KGP than at KOL over coastal WBGP
