Pollutant variability in the area represented by a stationary point monitoring site causes an uncertainty in representative sampling. This uncertainty has been determined for selected sites in the Regional Air Pollution Study (RAPS) in St. Louis by using portable sampling and monitoring equipment. RAPS ozone concentrations averaged over twenty minutes are linearly related to the values taken in the surrounding area with almost 1:1 correspondence at both urban and rural sites. Carbon monoxide values are linearly related at the rural site but not at the urban site.
