Abstract
The literature suggests that Delhi and its neighbouring areas have witnessed increases in air pollution and population (Kumar and Foster, 2007; Narain; Census of India). [...]the chosen study area is important for assessing the trend of air pollution (inside and outside the city) before and after the interventions, and the association shed light on the direct and indirect effects of environmental interventions on local and regional air pollution. [...]AOD is an indirect proxy of air quality (Chen et al., 2013; Kumar et al., 2013). [...]annual trends of AOD can provide indirect measures of changes in air are changing with the growth in numbers of new vehicles and industries.\n in AOD; for example, the total increase in built-up areas, largely concentrated in the southern parts of the study area, was 0.68 percent, and the increase in AOD in these areas was more than 0.1 (~14.9 percent of the average AOD value).
