摘要：

We conducted the campaign studies on Black Carbon (BC) aerosol measured at two different locations such as semi-arid rural, Anantapur (ATP) and tropical wet and dry urban, Tirupati (TPTY) of Andhra Pradesh. The campaign took place from June 1 to June 30, 2015. We studied diurnal variations and weekdays/weekends differences of BC mass Concentration and its correlations with meteorological parameters for two sites. BC exhibits a strong weekly cycle in which weekend concentrations are significantly lower than weekday concentrations by similar to 14 and 31% for ATP and TPTY due to the decrease in the local traffic volumes during weekends due to a well-known 'weekend effect'. An estimation of percentage of contribution of BC indicates the main sources of BC as fossil fuel combustion and which is dominantly observed at TPTY than at ATP. Finally, the influence of the transported air masses has also been discussed with the help of HYSPLIT air mass backward trajectories.
