Abstract: Urban expansion and microclimatic modification both are correlated with each other. Urban expansion is changing the urban microclimate and destroy the standard air components in the urban region. Urban Air pollutants are day to day increase due to rapid population explosion in these selected cities. The objective of this paper is to provide insight details about the increasing rate of different air pollutants in different cities in India. Assess the spatiotemporal changes in air pollutants at different times in various cities. Comparison between Environmental Determinism and Anthropogenic Determinism for Urban microclimate modification. The National Air Quality Index (NAQI) ensures comparison amongst various cites of various air pollutants with different times. In this paper, I assess the Landsat 8 (libra.developmentseed.org) data also using the important reference coordinate systems, like Universal Transverse Mercator (UTM), World Geodetic System 1984 (WGS84) North Zone 45. I used the originally 2014 and 2018 satellite images, which urban growth image created by the use of three bands (B2 - Blue, B5 - Near Infrared, B7 - Shortwave Infrared 2). This series satellite image is used to show only the urban density analysis of various cities. A significant correlation between urban expansion due to population explosion in selected cities based on geospatial analysis and Air pollutants level dynamic change with the different time.
