Particulate chloride (Cl–) can be transformed to nitryl chloride (ClNO2) via heterogeneous reaction with nitrogen pentoxide (N2O5) at night. Photolysis of ClNO2 and subsequent reactions of chlorine radical with other gases can significantly affect the atmospheric photochemistry. In China, the only available integrated anthropogenic chloride emission inventory was compiled in the 1990s with ...
