Short summary
Aerosol physiochemical properties were characterized for three prominent air masses over New Delhi, a highly polluted megacity. The chemical composition and size distribution data were used to deduce the hygroscopicity parameter and cloud condensation nuclei (CCN) number concentration. The activated fraction was the highest in the world for any continental site. The aerosol physiochemical properties and their diurnal patterns were interlinked and impacted aerosol hygroscopicity and CCN activity.
