This is the second semi-annual report of the "Pittsburgh Air Quality Project" (PAQS)
funded by the U.S. Department of Energy's National Energy Technology Laboratory
under DOE Cooperative Agreement No. DE-FC26-01NT41017 to Carnegie Mellon
University. This work is also supported by the US EPA through the Supersites program.
In this three-year project, Carnegie Mellon University will conduct detailed studies of the
ambient particulate matter in the Pittsburgh, PA metropolitan area. The work includes
ambient monitoring, source characterization, and modeling (statistical and deterministic)
for source apportionment. The major objectives of the project include:
" To achieve advanced characterization of the PM in the Pittsburgh region.
Measurements include the PM size, surface, volume, and mass distribution; chemical
composition as a function of size and on a single particle basis; temporal and spatial
" To obtain accurate current fingerprints of the major primary PM sources in the
Pittsburgh region using traditional filter-based sampling and state-of-the-art
techniques such as dilution sampling and single particle analysis using mass
spectroscopy and LIBS.
" To estimate the impact of the various sources (transportation, power plants, natural,
etc.) on the PM concentrations in the area using both statistical and deterministic
" To quantify the responses of the PM characteristics to changes in these emissions in
support of the emission control decision making in the area.
" To develop and evaluate current and next generation aerosol monitoring techniques
for both regulatory applications and for determination of source-receptor
SUMMARY OF TECHNICAL PROGRESS
This section provides an overview of the progress made on the various project
activities. This project period the majority of the effort went into activity 2 ambient
monitoring; more limited effort was spent planning the upcoming source characterization
effort and in the continued development of three-dimensional air quality models.
Activity 1. Project Management
During this project period the first data analysis workshop was held to review data
from the Summer 01 intensive sampling period and to coordinate future work. The
workshop was held on December 13 and 14 at Carnegie Mellon University. Personnel
from Carnegie Mellon University also participated in the EPA Supersites data workshop
held on November 13 and 14 in Research Triangle Park, NC.
Here’s what’s next.
