Short summary
Delhi experiences particulate matter concentrations that are among the highest in the world. We conducted a long-term campaign to make highly time-resolved measurements of submicron particle (PM1) chemical composition in Delhi. Our dataset illuminates key sources and atmospheric processes that impact Delhi's PM1 concentrations, with sharp differences among seasons and between day and night. In addition to local sources, Delhi's PM1 levels are amplified by regional pollution and meteorology.
