The 1997 Southern California ozone study-NARSTO: Supplemental air quality sampling network
- California Air Resources Board, Sacramento, CA (United States)
Characteristically, air pollution monitoring sites are located in urban areas where the health impacts of air pollution are of greatest concern. However, to understand the formation and distribution of ozone on a regional scale, additional monitoring is needed in areas where the recirculation and transport of ozone and ozone chemical precursors may occur. This is especially important aloft, where the formation and distribution of ozone concentrations measured during previous studies in southern California are understood inadequately. To better understand the distribution of ozone on a regional scale, the SCOS97-NARSTO provided for an expanded network of air quality measurements at the surface and aloft. The expanded network included an increased number of monitoring sites. Speciated volatile organic compounds (VOC) measurements were taken four times daily during each intensive operational period (IOP). Monitors to measure total reactive nitrogen species (NOY) and nitric acid were also deployed. Air quality measurements aloft were conducted using six aircraft, seven ozonesonde sites, and two ground-based lidars. The design of this network and the expected uses of these data for air quality modeling are described.
