Objectives of the Project:
The broad objective
of this Project is to develop and implement an improved, sustainable and transferrable
program of (a) monitoring local air quality and (b) providing timely and effective
public access to useful information about air quality and related meteorology
for metro Birmingham and its regional environment (southeastern and eastern
USA). The air quality monitoring and public outreach activities and focus
are to be expanded in several major ways, each constituting a significant
innovation in the way local agencies and communities encounter air quality.
Our specific objectives and approach are outlined below in the form of specific
Project Tasks:
Task 1. Continue the present program of air quality monitoring and
public access;
Task 2. Expand the continuous monitoring program for PM2.5, particularly
to explore urban-regional exchanges;
Task 3. Extend program focus from mainly ozone to ozone and PM2.5;
Task 4. Extend program focus from local only to local and regional;
Task 5. Extend forecast modeling capability for meteorology and chemistry,
utilizing both upgraded statistical modeling and state-of-the-art real-time
3D Eulerian grid modeling for ozone;
Task 6. Extend timely and effective public outreach via internet, the
news media, and other means;
Task 7. Provide for local program sustainability and national program
transferrability.
Progress/Accomplishments Report (by Task):
Year 1 activities have been mostly of a developmental nature. The focus in
Year 2 will shift more to completing the development of the program, to testing
its performance, improving it, and documenting/institutionalizing the process
for sustainability and national transferability. This section is a brief task-by-task
summary of the items noted above, documentation of what was accomplished in
Year 1.
Task 1: Continuation of pre-existing program.
The pre-existing program of air quality (AQ) management for the Birmingham
Ozone Non-attainment Area (BONA) of Jefferson and Shelby Counties (see Fig.
1), consisting of the following, was continued during 2001:
- Continuous AQ monitoring -- ozone (9 sites), CO (2 sites), SO2 and NOx (1
site), PM2.5 (1 site);
- 24-hour average sampling and analysis of PM2.5 -- every day (2 sites) and
every three days (6 sites);
- Daily ozone forecasting based on statistical modeling using local input
variables only;
- Public outreach involving local educational programs and sharing daily ozone
forecasts with selected
stakeholders.
Task 2: Expansion of the local continuous monitoring program
Six new continuous monitors of PM2.5 were purchased (four with EMPACT funds),
tested and installed during the first half of the year, and were in operation
from about August 1. Four of them were installed at rural sites in the periphery
of the BONA (Pinson, Corner, Providence and McAdory) to capture information
about regional inflow/outflow of PM2.5 relative to the urban area; the other
two were installed at urban-suburban sites (Wylam and Hoover), and complement
the one already in existence at the N. Birmingham site. Each of these seven
sites now has a Ruprecht & Patashnik Model 1400ab Continuous Particle
Analyzer or a TEOM (Tapered Element Oscillating Microbalance) to monitor the
particle concentrations, as well as a new ESC Data Logger to transmit the
data to the central computer seven times a day (to be increased to hourly
in 2002). The central computer subsequently sends the data to the main EMPACT
web site at UAH at the end of each polling session. Ozone is also monitored
continuously at each of the seven continuous PM2.5 sites. A new ozone monitoring
site was also added in 2001 at a rural peripheral site in Leeds (Jefferson
CO). In addition, a new continuous SO2 monitor was installed at one of the
ozone monitoring sites (Fairfield).
Task 3: Extension of program focus from ozone only to ozone and PM2.5
With the installation of the PM2.5 continuous monitors at seven of the eleven
monitoring sites, in addition to monitoring of ozone at ten sites (all except
Wylam), program focus has now definitely been expanded from ozone only to
ozone and PM2.5. The PM2.5 program also includes 24-hour-average filter sampling
at eight sites (daily at two sites and every three days at six sites), seven
of them co-located with the continuous PM sites (the eighth one at Helena).
These samples are routinely analyzed for chemical composition.
Task 4: Extension of program focus from local only to local and regional
A major new innovation of the Birmingham AQ management program has been the
expansion of its focus from local only to local + regional. We have done this
in terms of both observational information and modeling information. Observationally,
two new elements have been added: (a) the continuous monitoring of both ozone
and PM2.5 not only at urban-suburban sites but also at a number of rural sites
in the periphery of the BONA (this provides specific information to track
regional inflows/outflows of these two secondary pollutants relative to metro
Birmingham, and to distinguish regional impacts locally from local contributions)
and (b) daily tracking of regional (Eastern USA) midday ozone distribution
(AIRNOW contour maps) for the past four days, providing a dynamical perspective
also of regional ozone pollution. In addition, we have also successfully implemented
a daily local-regional quantitative program of ozone forecasting based on
real-time photochemical modeling in forecast mode. At the same time, we have
also continued our daily ozone forecast program based on local statistical
modeling.
Task 5: Extend forecast modeling capability for meteorology and chemistry
Under this Task, we had two main objectives: (a) to upgrade the statistical
ozone forecasting by including the role of regional ozone transport (by changing
the use of todays observed ozone in the statistical formula for predicting
tomorrows peak ozone from the locally-observed value to that observed
in the upwind airmass predicted to arrive in Birmingham tomorrow); and (b)
to
implement and test the utility of a comprehensive uban-regional photochemical
ozone forecast modeling system (including the role of regional ozone transport
and chemistry) as an additional input to local ozone forecasting. Task (5a)
remains to be accomplished during 2002, but we were able to successfully implement
Task (5b) -- a Real-Time Ozone Forecast System (RTOFS) based on urban-regional
meteorological/ emissions/photochemical modeling, and we are currently in
the process of testing its utility in local ozone forecasting.
Task 6: Public outreach
The main new element in the area of public outreach has been the development
of a new web site at UAH. Links to the web site will be available from the
JCDH and ADEM web sites. The developmental work is still continuing and the
new site will be opened to the public at the beginning of the 2002 ozone season,
in fully operational status. Particularly since it is possible for the Birmingham
area to be designated in attainment of the 1-hour ozone NAAQS at the end of
the 2002 ozone season, an intense public outreach campaign is being planned,
to be launched in conjunction with a special media event to promote the Birmingham
EMPACT program. We plan to inaugurate the new web site at that time. Our public
outreach program has other elements also. Local media services have been extremely
supportive of getting news about air quality to the public (especially noteworthy
were The Birmingham News, The Birmingham Post-Herald, and local television
meteorologists from NBC, ABC, and FOX6 affiliates). Stakeholders in the local
ozone action program, especially the Alabama Partners for Clean Air (APCA),
have also helped to provide "timely public access to air quality information."
Educational programs have been numerous and have included outreach programs
to approximately forty neighborhood associations, to many public and private
schools, as well as colleges and universities (one of the APCA members alone
spread the air quality news to 35,000 students), and to many civic-social,
business, and environmental groups.
Task 7: Program sustainability and national transferrability
In Year 1, the focus was on program development. The task of program sustainability
and national transferrability will be met in Year 2.
Future
Activities (by Task):
Continue the following tasks in Year 2:
Tasks 3, 4: Regional visibility mapping as a surrogate for PM2.5.
Task 6: Public Outreach.
