Extensive field evidence for the release of HONO from the photolysis of nitrate aerosols

Science Advances, 2023
Particulate nitrate (pNO3−) has long been considered a permanent sink for NOx (NO and NO2), removing a gaseous pollutant that is central to air quality and that influences the global self-cleansing capacity of the atmosphere.

Aerosol–photolysis interaction reduces particulate matter during wintertime haze events

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Aerosol–radiation interaction (ARI) not only constitutes one of the major uncertainties in climate prediction, but also significantly deteriorates particulate matter (PM) pollution during heavy haze events.
