Abstract:
<span" roman"="Roman"" new="New">
The long term observations of aerosol properties from ground-based instrument indicate that aerosol type of mineral dusts, smoke plumes and anthropogenic pollutants can be potentially identified with the characteristics of optical properties, such as Ångström exponent (AE) and Single Scattering Albedo (SSA). However, the retrieval of SSA is not frequently available for the application over some of regions from both ground-based observations and satellite retrievals while aerosol optical depth (AOD) can be provided frequently. In order to overcome such kind of limitation (lack of SSA information), this study aims at the spectral variance in AOD for the discrimination of the aerosol types under the constraint on an equivalent amount of particulate matter (PM). The performance of proposed approach in discrimination smoke aerosols from anthropogenic pollutants are examined with MODIS data. After the compared with ground-based observations from AERONET sites and aerosol subtype of CALIPSO product, the results show the well agreement implying that the variation of spectral property within the similar PM concentration is highly practical for the discrimination of aerosol types.Keywords: Biomass Burning, Anthropogenic Pollutants, Spectral Property, MODIS, AERONET, CALIPSO
