Seasonal Variability of Satellite-Derived Aerosol Optical Depth in Smart City, Bhubaneshwar
With the increase in industrialization and urbanization, the environment is being polluted by the addition of harmful products by the anthropogenic activities of human beings. The rapid increase in population accounts for the aerosol concentration that is increasing with time and having a significant impact on climatic conditions. The study focuses on the variation of aerosol optical depth (AOD), Angstrom exponent (AE), concentrated weighted trajectory (CWT) and potential source contribution function (PSCF) in smart city Bhubaneswar in the year 2017. The present study analyses MODIS (Moderate Resolution Imaging Spectroradiometer) data in the year to estimate the AOD level. Results show that the daily mean value for AOD and AE from the satellite data product showed the range falls between 0.16–2.17 and 0.01–1.80, respectively. The corresponding monthly mean for AOD in winter, summer, monsoon and post-monsoon is found to be 0.27 ± 0.16, 0.22 ± 0.05, 0.24 ± 0.1 and 0.18 ± 0.02, respectively. Similarly, the values for AE for the above seasons are obtained as 1.53 ± 0.10, 1.52 ± 0.1, 1.19 ± 1.05 and 1.61 ± 0.09, respectively. The CWT and PSCF are analysed for the seasons of winter (DJF), summer (MAM), monsoon (JJA) and post-monsoon (SON) in the given year.
