Abstract |
The photochemical process responsible for ozone formation is the oxidation of nitrogen oxides (NO and NO2), referred to as NOx, in the presence of nonmethane hydrocarbons. In the process NOx is itself oxidized to more stable products such as HNO3 and peroxyacetyl nitrate (PAN). New measurement capabilities (low concentrations and new species) are allowing us to gain an improved understanding of this nitrogen chemistry in the rural environment. An important element of the evaluation of regional models with regard to photochemistry is a comparison of the resultant species of the NOx oxidation process predicted by the model with the resultant species observed in the 'real world.' The dynamics are inferred from species concentration relationships. |
