Snow‐Induced Perturbations in Nitrous Acid (HONO) Levels: Insights Into Heterogeneous Reactions During Wintertime in Mid‐Latitude Regions

Snow‐Induced Perturbations in Nitrous Acid (HONO) Levels: Insights Into Heterogeneous Reactions During Wintertime in Mid‐Latitude Regions

Abstract Nitrous acid (HONO) governs wintertime hydroxyl radical (OH) production, critically linking radical cycling, tropospheric oxidative capacity, and air pollution. During a mid‐latitude snowfall event, rapid HONO enrichment was observed alongside concurrent depletion of other pollutants. This...
