Abstract

Absorbing aerosols uniquely impact radiative forcing, aerosol chemical transport, and meteorology. This paper uniquely quantifies BC core and sulfate shell size and mass using decadal measurements of multi-spectral AOD, SSA, and AE from AERONET stations located throughout East, Southeast, and South Asia, in connection with a MIE model. All sites are uniquely characterized into four types: urban, biomass burning, long-range transport, and clean. The size and mass of the core and shell are calculated as probability distributions, and found to be unique within each classification. Well known urban, biomass burning, and clean sites are all properly identified. Furthermore, two unique sites previously thought to not have multiple characteristics are identified, with urban and biomass burning significant in Beijing and long-range transport significant in the otherwise clean South China Sea at Taiping island. It is hoped that these results will allow for advances in attribution and radiative forcing studies.
