Elucidating the chemistry of particulate and chlorinated nitrates in the troposphere through method development, and chamber and field studies ...
This thesis explores the chemistry of chlorinated and particulate nitrogen oxides in the troposphere which can impact the budgets of atmospheric oxidants and aerosol. Mixing ratios of nitryl chloride (ClNO2) were measured by chemical ionization mass spectrometry (CIMS) during the ORCA campaign in Ju...
