<p>The present study deals with the concentration of blue aerosol in the lower atmosphere and its modeling for the assessment of the climate of the Barrackpore municipal area (BMA). Since the concentration of blue aerosol is not spatially correlated, its modeling seems to have a meager relation with the municipal boundary. The present study utilizes SIR-C images to find out the concentration of blue aerosols since these images contain microwave sensing to estimate the depth of the aerosol layer. Here, the aerosol optical depth (AOD) in the blue band ranges between 0.01 (extremely clean) and 1.0 (extremely polluted). The results show that the concentration of blue aerosol is found to be higher near the major river Hooghly, whereas itsr concentration is found to be lower in the rural counterpart. The concentration of blue aerosol is found to be higher in the evening, increasing the harshness of the city climate in the nighttime. The normal QQ plot shows the linear positive relation between the theoretical and actual observations, indicating the significance of the observation at the 0.01 level. The study concludes with the finding of the discontinuous and heterogeneous nature of blue aerosols through the computation of neighborhood functions, where the root mean square error (RMSE) value is found to concentrate near 0.2 (less error).</p>
