The major emphasis of this investigation centered on the collection of particulate and gaseous pollutant data, and detailed micrometeorological data in a non-urban setting adjacent to the heavily travelled Long Island Expressway. The purposes for collecting the data were to (1) document the distribution of sulfate, lead, total particulates and carbon monoxide at an array of sampling points adjacent to the highway; (2) study the micrometeorology associated with the highway, with special attention to those parameters important in the determination of atmospheric dispersion, (3) reevaluate highway air pollutant emission factors from data gathered in tracer gas experiments; and (5) examine the applicability of existing highway air pollutant dispersion models. The location of the sites and the experimental setup for collecting pollutant data are described, and details of the data acquisition procedures are presented.

The major thrust of this investigation was the collection of data on particulate and gaseous pollutant concentrations, and detailed micrometeorological data in the vicinity of a major highway in a non-urban setting. A site on a relatively undeveloped section of the heavily travelled Long Island Expressway was selected for the collection of this data for the purpose of: (i) documentation of the distribution of sulfate, lead, total particulates and carbon monoxide at an array of sampling points adjacent to the highway; (ii) studying the micrometeorology associated with the highway, with special attention to those parameters important in the determination of atmospheric dispersion; (iii) reevaluating highway air pollutant emission factors from data gathered in tracer gas experiments; and (iv) examining the applicability of existing highway air pollutant dispersion models. The location of the site and the experimental setup for collection of pollutant data are described. Details of the data acquisition procedures also are presented in this report.
