Abstract Areas within which the National Ambient Air Quality Standard (NAAQS) for ozone is likely to have been exceeded are shown to be related to the observed annual second-maximum ozone concentrations. All sets of SAROAD stations separated by 500 km or less that had nearly complete annual data sets were considered for the years 1974 to 1977 to determine the probability that the NAAQS would be exceeded at one station of the pair, given the observed second-maximum ozone concentration at the other and their separation. Circles were drawn around each SAROAD monitoring site to show the area within which it is 95 % probable that the 120 ppb NAAQS has been exceeded for two or more hours during one or more years. The report describes meteorological situations and seasons during which high ozone concentrations are most likely in various parts of the country, so that special monitoring studies can be designed to supplement existing data. An aircraft monitoring protocol is given that will provide observations that are representative of ground-level conditions. Conditions that cause ozone data to be unrepresentative are described as are uncertainties associated with instrumental and calibration factors.
