Black carbon (BC) aerosol formed from incomplete combustion of fossil fuel and biomass combustion is collected at an educational institute, Madurai Kamaraj University, Madurai located in Southern India. The sampling is done using an Aethalometer (AE-31) from January to March (2015 to 2017) to study the effect of meteorological parameters and anthropogenic activities during the transition from winter to summer. BC identified from a variety of sources showed strong diurnal variation with two peaks, first one at early morning hours and the ot. her one at evening hours, but this peak timings varied with the seasons. It is observed that biomass combustion and tobacco smoke at the study site dominates other sources. Raman spectral analysis showed strong organic source peak.
