Abstract Delhi is facing severe air pollution and the government has set up air pollutant monitoring network to inform the public and increase the understanding of air pollution events. One year-long air pollutants data collected from the network were analyzed in this study. This is the first time to the spatial and temporal variations of particulate matter with aerodynamic diameter less than 2.5 µm (PM2.5) and less than 10 µm (PM10) as well as gaseous species were studied in Delhi using hourly data from 8 sites during 2017. Delhi is facing tremendous air pollution as all major pollutants have concentrations reaching severe pollution levels. Seasonal variations are analyzed and correlations between different pollutants and same pollutants at different sites are investigated. In addition, three extreme PM2.5 events (hourly average concentration exceeding 300 μg/m3 for ~40 hours) are examined with the consideration of meteorological conditions. This study can greatly support the research on formation, transport and human health effects of air pollutants in Delhi and India.
