Study of aerosol behavior on the basis of morphological characteristics during festival events in India

► Concept of setting velocity was used to assess impact of festival events on the atmosphere chemistry. ► SEM-EDX analysis was used to determine terminal setting velocity. ► Correlation between BC, AOC and aerosol load was used to determine the settling time of the aerosols. ► Role of morphology of aerosols in altering the atmospheric chemistry was also highlighted in the study.
