NARSTO EPA Supersite (SS) Pittsburgh Gas Concentration and Particulate matter (PM) Physical Properties Data

Description

NARSTO_EPA_SS_PITTSBURGH_GAS_PM_PROPERTY_DATA is the North American Research Strategy for Tropospheric Ozone (NARSTO) Environmental Protection Agency (EPA) Supersite Pittsburgh Gas Concentration and Particulate matter (PM) Physical Properties Data product. Data was obtained between May 23, 2001 and September 1, 2002 during the Pittsburgh Air Quality Study (PAQS). The data set provides Particulate Matter Composition Data of the following types: 1) Total, Organic, and Hydrogen Peroxide data 2) Filter based measurement of PM10 and PM2.5 Mass concentration using a Dichotomous sampler 3) Epiphaniometer total particle active surface area 4) Filter based measurement of PM2.5 Mass using the Federal Reference Method 5) Integrating nephelometer based measurement of PM2.5 light scattering 6) TSI Scanning Mobility Particle Sizer (Long-column/model 3936L10) 7) Measurements of PM mass size distribution using a MOUDI cascade impactor 8) In-situ VOC measurements by pre-concentration and gc/msd/fid9) Surface air concentrations of O3, NO, NOx, SO2, CO, and PM2.5 mass. Pittsburgh Air Quality Study (PAQS), along with the Pittsburgh Supersite Program, was a comprehensive, multi-disciplinary investigation to characterize the ambient PM in the Pittsburgh region, to improve understanding the links between ambient PM and public health, and to develop new instrumentation for PM measurements. The Pittsburgh supersite was designed to achieve several objectives: to determine the physical and chemical characteristics of PM in the Pittsburgh region; to develop and evaluate the next generation of atmospheric aerosol monitoring techniques; to update emission profiles for important regional sources; to quantify the impact of the various sources on the local PM concentrations; and to predict changes in the PM characteristics due to proposed changes in emissions. The last objective was based on concurrent modeling studies and was designed to support the development of regulations. These objectives were addressed through four components of the research: (1) ambient monitoring at a central site and a set of satellite sites in the region; (2) an instrument development and evaluation study; (3) a data analysis and synthesis component; and (4) a comprehensive modeling component. The central supersite was located on a grassy hill in a large urban park adjacent to the Carnegie Mellon University campus, approximately 6km east of downtown Pittsburgh. It was separated from the city in the predominant upwind direction (south and west) by roughly 1km of parkland. It was at least several hundred meters from any other major source of air pollution: the site was positioned approximately 50m past the end of a dead end street, and several hundred meters from the nearest heavily traveled street. Five additional sites were operated as Satellite sites to character the spatial variation of the PM. The measurement campaign lasted for 14 months (July 2001-September 2002). Intensive monitoring was performed during two periods, from 1 July to 3 August, 2001 (ESP01) and 1 January to 15 January, 2002 (ESP02). Baseline monitoring was conducted for the rest of the study. Baseline measurements included daily filter samples for fine particle mass and composition (OC/EC, major ions, elemental composition). The U.S. EPA Particulate Matter (PM) super sites Program was an ambient air monitoring research program from 1999-2004 designed to provide information of value to the atmospheric sciences, and human health and exposure research communities. Eight geographically diverse projects were chosen to specifically address these EPA research priorities: (1) to characterize PM, its constituents, precursors, co-pollutants, atmospheric transport, and its source categories that affect the PM in any region; (2) to address the research questions and scientific uncertainties about PM source-receptor and exposure-health effects relationships; and (3) to compare and evaluate different method
