NARSTO-CE: A major Canadian field study of photochemical smog
- Environment Canada, Downsview, Ontario (Canada). Atmospheric Environment Service
The Canadian NO{sub x}/VOC Management Plan`s Science Program is comprised of three component parts: 1. scientific understanding of the formation and loss of ozone; 2. source/receptor modeling; and 3. emission controls and inventories. As part of this Program and Canada`s contribution to NARSTO, a major field study, called NARSTO-CE (Canada East), was carried out during May--September 1996, in coordination with a similar effort in the Ozone Transport Region of the US, called NARSTO-Northeast. The primary goal of NARSTO-CE was to collect air quality and meteorology measurements in order to improve the reliability in simulating source receptor relationships for tropospheric ozone. The Canadian field study was focused on two questions: (1) how accurately do the regional oxidant models developed under the NO{sub x}/VOC Management Plan`s Science Program represent the atmospheric chemistry of oxidant formation in an eastern North American setting; (2) how well does the MC2 meteorological driver in these models reproduce the dynamics of the nocturnal and marine boundary layers? There were several components under the overall NARSTO-CE umbrella: (1) airborne measurements of meteorological parameters to test MC2; (2) special chemistry measurements of smog products, intermediates and precursors at St.Anicet (a site upwind of Montreal), on Mt.Sutton in Quebec, and at Kejimkujik in Nova Scotia; (3) airborne and surface measurements in the Montreal area (which were also part of MAOS, the Montreal Area Oxidants Study), and in southern Ontario (part of SONTOS, the Southern Ontario Oxidants Study), and (4) upper air soundings at several sites using tethersondes, radiosondes and ozonesondes. This paper will describe the measurement program, and discuss some of the preliminary results. The future plans for use of the data in support of smog control policy development will also be discussed.
