Synergistic HNO$_{3}$–H$_{2}$SO$_{4}$–NH$_{3}$ upper tropospheric particle formation
New particle formation in the upper free troposphere is a major global source of cloud condensation nuclei (CCN). However, the precursor vapours that drive the process are not well understood. With experiments performed under upper tropospheric conditions in the CERN CLOUD chamber, we show that nitr...
