Changing aerosol chemistry is redefining HONO sources

Abstract Heterogeneous reactions of NO2 on particulate matter have been considered an important source of HONO (Nitrous acid) in the troposphere, whereas its contribution is controversial due to the lack of uptake coefficient of NO2 (γNO2) on the surfaces of ambient particulate matter (PM). Here we...
