Abstract During the period 1975-1977, 51 monitoring stations in California collectively recorded about 1,800 sit-days in which hourly nitrogen dioxide (NO2) concentrations exceeded 0.20 ppm. This work investigates potential causes of these high NO2 events, the physical phenomena involved in their occurrence, and their spatial and temporal patterns. In addition, the potential association between emission sources and the frequency and magnitude of high NO2 levels at the various locations is analyzed using detailed site-description data compiled in this study. The relationship between annual maximum hourly levels and annual mean concentration is explored, and the quality of the NO2 data is evaluated.
