Assessment of spatio-temporal variations in air quality of Jaipur city, Rajasthan, India

A severe deterioration of air quality in Jaipur, Rajasthan, is driven by high concentrations of suspended particulate matter (SPM) and PM10, particularly in winter and summer, with specific hotspots like Vidhyadhar Nagar, Civil Lines, Hawa Mahal, Kishanpole, and Aadarsh Nagar showing critical pollution levels. The study, analyzing data from 2004 to 2015, found that while NOX and SO2 concentrations remained within CPCB standards, the spatial distribution of Air Quality Index (AQI) revealed strong positive autocorrelation with weather parameters such as relative humidity, temperature, and wind speed. Using geo-spatial and geo-statistical techniques, including Ordinary Least Squares regression and bivariate Moran’s I analysis, researchers identified significant correlations between AQI and weather conditions during summer and winter seasons. This combination of GIS and statistical analyses highlights critical areas needing targeted interventions to mitigate air pollution in Jaipur.
