Visualization of Transboundary Air Pollutant Transport
to the US
Background.
Anthropogenic and natural pollutants generated in one country are regularly transported
to other countries adding to their air quality burden. This is particularly true for Persistent
Organic Pollutants (POP) that reside in the atmosphere for days or weeks.
The transboundary transport affects the seasonal and yearly average concentrations in the
US by elevating the ‘background’ levels. Local emissions are then superimposed on this
elevated background, leaving less margin for homegrown contributions. Transboundary
transport is also episodic, i.e. highly non-uniform in time.
This is a continuation of work conducted under the project: "Investigation of Regional
and Global Transport and Deposition of Persistent Organic Pollutants", a collaborative
research projected between the North Carolina Supercomputing Center (NCSC) and the
Center for Air Pollution Impact and Trend Analysis (CAPITA). The results of the
CAPITA contribution to that project are available at the webpage:

Goal of the Project
Overall goal of the work is to create visualizations of transboundary airmass transport to
the United States. The visualizations need to be suitable for presentation to national and
international policy analysts.
Specific Objectives of this Work
The previous analysis examined the probable airmass pathways to 9 receptor sites during
the spring of 1999. This proposed projected will expand on the previous work in three
ways:
1. Airmass history residence time analysis will be conducted for 12 receptor sites
including two sites in Alaska.
2. Airmass transport probabilities for the West Coast will be aggregated
3. Airmass transport pathways will be derived for all four seasons of 1999 as well as
the yearly average.
Approach
Residence time analysis will be used to estimate the probable airmass transport pathways
to the US border for each season as well as for the entire year of 1999. The residence
time analysis uses back trajectories to estimate the fraction of time airmasses reside over
a given region prior to impacting the receptor. By placing a uniform grid over a region
and calculating the fraction of residence time for each cell residence time probability
maps can be constructed. The most probable airmass pathways are then the regions with
the highest airmass residence probability.
This analysis will use an airmass history database consisting of ten day airmass histories
for receptor sites space ~ 100 km apart along the boundaries of the conterminous US and
Alaska. The airmass histories will be calculated every 6 hours over the year 1999 using
the CAPITA Monte Carlo Model driven by the FNL global meteorological data. The
FNL data will be obtained from the Air Resource Laboratories READY website and be
reprocessed for suitable input into the Monte Carlo Model.
Residence time probability fields will be calculated for each receptor site in the database
for a winter, spring, summer and fall seasons of 1999, where the winter season is
comprised of the months December, January, and February. The residence time analysis
for West Coast, will be conducted by integrating the residence time analyses for each
receptor along the West Coast.

Output of the Work
The main product of this work will be seasonal and yearly maps of airmass transport
probabilities to each of the receptor site as well as to the West Coast. The general map
layout is illustrated below.
We will also explore additional displays including animations and 3D rendering of
transport.
Schedule
The work will be conducted during August, 2000 – April, 2001. Intermediate
visualization outputs will be discussed with the Project Officer, Angela L. Bandemehr.
Budget
The budget for the project is $30,000. 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. He will be assisted by one or two graduate
students. Dr. Bret Schichtel will serve as a consultant to the project regarding the
trajectory computations.
