Abstract

Equivalent black carbon (EBC) aerosols, produced from incomplete combustion processes of fossil fuel
and biomass burning at a semi-arid site, is collected using aethalometer instrument from June-2014 to
May-2016 to understand its absorption characteristics. The variation in EBC mass concentration was not
only due to anthropogenic activities, but also due to changes in the atmospheric boundary layer height.
The variation of EBC is highly influenced by the wind speed at the study site. Aerosol Optical Depth
(AOD) has good correlation with rainfall and a poor correlation with EBC at the study site indicating the
dominance of other aerosols at the location.
