Regional Haze and PM2.5 Analysis
Background
This is a brief proposal to EPA OAQPS as part of the Cooperative Agreement CX
825834 "Ozone and PM Air Quality Analysis in Support of Public Needs" between EPA
and CAPITA.
The new haze regulations will require the states to estimate the level of haze based upon
the chemical composition of the dry ambient aerosol. The states as well as the general
public needs to better understand the causal mechanism for haze as well as the
relationship between the measured PM2.5concentrations and the haze regulations. The
purpose of the proposed analysis is to provide background information on haze including
the PM2.5-haze relationship. The information will be presented in such a way that it can
aid all the main stakeholders involved including federal, state and local agencies as well
as the interested public.
In addition, the first year of the FRM PM2.5 data, collected by the National fine particle
monitoring network, is due to be delivered by the States to AIRS by March 31, 2000.
CAPITA will cooperate with OAQPS in obtaining and exploring these data, followed by
initial analysis of these data.
The specific goals of the this sub-project has three parts:
1) Write a chapter on haze for the PM Analysis Workbook.
2) Explore the first year of FRM PM2.5 data examining the content of the database, its
quality and generating overall statistics.
Haze Chapter for the PM Analysis Workbook
The new haze regulations require states to establish baseline haze levels and the natural
conditions, i.e. haze levels that would exist without anthropogenic contributions, for all
Class I areas. In addition, all states will need to access their contributions to haze in
Class I areas and provide State Implementation Plans to remove their contributions to the
anthropogenic haze in the Class I areas. The PMfine workbook haze chapter will contain
three sections to aid states in complying with the new haze rules.
1) Background information on the physical mechanism responsible for haze.
Many states are unfamiliar with the causal factor of haze. Therefore, a section
that provides background information on haze from the nature of light to its
interaction with ambient particles will be provided. There are a number of
excellent sources of information on the causes of haze such as the 1978 Visibility
Report to Congress, the NAPAP report Volume 24 and the more recent
publication "Introduction to Visibility" by William Malm that will be drawn upon
for this section.
2) Relationship between haze and PM2.5. The new haze regulations require
haze levels to be estimated from measured aerosol samples. This section of the
workbook will describe the relationship between haze and PM2.5, as well as
established technique for reconstructing haze from the measured aerosol samples.

3) Fine mass and haze patterns and trends. National and seasonal patterns of
the PM2.5 mass, its constituents and the haze levels reconstructed from the
aerosol data will be presented. In addition National haze maps derived from
visibility airport concentrations and their long-term trends, i.e. from 1940-95, will
be presented. Last, estimates of the natural background levels as report in the
NAPAP report will be provided.
Exploration of FRM PM2.5 Data - Year 1
The national PM2.5 network has been in operation since January 1999 and the first year
of data will be available from AIRS for analysis in early April. CAPITA will cooperate
with OAQPS in the initial analysis of these data in four ways:
1) Enhancing the data availability. The FRM PM2.5 data will be available
from the EPA AIRS database. Experience has shown that there are a number of
resistances to accessing AIRS data which are difficult for most people to
overcome. Therefore, CAPITA will obtain all FRM PM2.5 data from AIRS, and
reformat it into ASCII and Voyager files. These resulting data files will be made
available via the PMfine workbook website.
2) FRM PM2.5 monitoring sites and data collection statistics. The overall
distribution of the data will be documented. This will include maps of the
location of the monitoring sites, the monitoring sites starting dates and the
monitoring sites collection statistics.
3) Quality assurance and control of the database. Initial quality assurance and
control will be conducted by examining the data for each site for spatial and
temporal consistency. This cursory examination will be designed to identify
outlying data points.
4) PM2.5 data analysis. Simple statistical analyses examining overall spatial and
temporal patterns of the data will be conducted. These analyses will include
examination of PM2.5 seasonal maps as well regional statistics including, mean,
standard deviation, and the upper and lower percentiles.
The initial exploration of the database will be completed by the end of May, in time for
EPA's initial FRM PM2.5 data report. More detailed data analysis of the data will
continue after May. The exact analyses to be conducted will be guided by the results of
the initial analysis and feedback from interaction with the data users.
Schedule
The work will be conducted during August, 2000 – April, 2001. Intermediate outputs will
be discussed with the Project Officer, Lara Autry.
Budget
The budget for the project is $40,000. The detailed budget is listed in the attachment. The
project will be conducted through incremental funding to the Cooperative Agreement CX
825834 between EPA and CAPITA “Ozone and PM Air Quality Analysis in Support of
Public Needs”

Personnel
The project will be conducted by Professor Rudolf B. Husar, director of the Center for
Air Pollution Impact and Trend Analysis. One or two graduate students will participate in
the project. Drs. Stefan Falke and Bret Schichtel will serve as consultants to the project.
