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.
