| Abstract |
Aerometric data were examined to define relationships between atmospheric NO2 and its precursors. A descriptive and critical analysis of the nationwide data base of NO2 was carried out, followed by the formulation application and testing of empirical models relating ambient NO2 changes to NOx and hydrocarbon (HC) emission controls. The examination showed that (1) other factors being constant, annual mean and yearly maximum NO2 are proportional to NOx input; (2) HC control yields slight-to-moderate reductions in yearly maximum NO2; (3) HC control yields essentially negligible benefits for annual mean NO2; and (4) the exact form of the NO2/precursor relationship may vary somewhat from one location to the next, depending on local conditions. |
