In this paper, the tropospheric aerosol load morphological classification and its impact on temporal variation of visibility are investigated using a continuous 23-hour single channel CSIR-NLC mobile LIDAR backscatter measurement. The trajectory of the air mass that arrived at the measurement site was traced back using online HYSPLIT model. The visibility range has been calculated and presented, using average aerosol extinction co-efficient profile and assuming that the atmosphere is homogeneous. The results show that the measurement site is loaded predominantly in the middle and upper troposphere by a transported hazy air-mass.
