Abstract Oxidant concentrations exceeding 160 microgram/cu m were observed at many locations in a seven-county area in southern California from February 25 to March 4, 1975. Because this was a violation of the air quality standard at a time when relatively low concentrations were normally anticipated, the meteorological conditions associated with this large scale episode were evaluated. A more complete understanding of the meteorology associated with the episode should provide a better background for devising an abatement strategy. The episode was associated with very slow air movement, slightly elevated temperatures, abundant solar radiation, limited vertical mixing at the coast, and vertical mixing varying from negligible at night to relatively deep in the daytime at inland sites. The maximum temperatures were 3 to 6 C cooler than those normally associated with high oxidant concentrations, but the solar radiation, as deduced from sky cover and sunshine records, was about equivalent to that at the end of the usual oxidant season. The differences in vertical mixing, combined with the overall stagnation and weak sea breeze at the surface in the afternoon, appeared to cause the oxidant concentrations to be higher inland.
