Atmospheric measurements of trace oxides of nitrogen, are at variance with accepted photochemical theory. In particular, measured NO3 levels at night are lower than expected from photochemical equilibrium, observed HONO concentrations increase throughout the night, and HNO3 or NO3 - is produced rapidly in cloud and plume. We investigate theoretically the potential role of wet particles in the chemistry of NO3, HONO, and HNO3 through a model that incorporates H-N-O photochemistry and a heterogeneous scavenging parameterization. -from Authors
