The impact of different nitrous acid sources in the air quality levels of the Iberian Peninsula

Hydroxyl radical (OH) is a primary oxidant in the atmosphere and affects both gasphase pollutants and particulate matter levels. Nitrous acid (HONO) acts as an important source of OH in the urban atmosphere. Therefore it is important to account accu- 5 rately for HONO sources within air quality mode...
