Abstract
On 6-7 July 2002 a nearly stationary upper level circulation over Maine produced an extended fetch of northerly flow that transported smoke into the mid-Atlantic and New England regions from wildfires 1500 kilometers north of Philadelphia, PA, where an air quality study was being conducted. Continuous measurements of trace gases (CO, SO2, O3, NO/NO2/NOX), fine particle mass from three ambient samplers (TEOM, CAMM, and RAMS), EC/OC, β-scattering coefficients and PM2.5, and conventional meteorological data were being collected at the surface, while a tethered balloon and RASS profiler documented aloft distributions of PM2.5, virtual temperature, and wind velocity. The measurement campaign was part of the Northeast Oxidant and Particle Study (NE-OPS), an investigation of meteorological and chemical processes that control the evolution of air pollution events in near-urban environments. NEOPS is part of the North American Research Strategy for Tropospheric Ozone (NARSTO), and the site is located at the Samuel Baxter Water Treatment Plant 18 km northeast of center city Philadelphia. Intensive observing campaigns (IOPs) have been carried out at this location during the summer seasons of 1998, 1999 and 2001. In July 2002, a continuation of this project was conducted under the sponsorship of the Pennsylvania Department of Environmental Protection (PA-DEP).
