Sources of carbon emissions
In 1996, the United States produced 1,463 million metric tons of carbon, or about 24 percent of the world’s total.

Ip =
IHi – ILo
(Cp – BPLo) + ILo
BPHi - BPLo
Ip
= the index for pollutant p
Cp = the rounded concentration of pollutant p
BPHi = breakpoint greater than or equal to Cp
BPLo = breakpoint less than or equal to Cp
IHi = AQI value corresponding to BPHi
ILo = AQI value corresponding to BPLo

Air Pollution Study Sites
Oxford, Mississippi - MS Highway 6
(Skyborne DIAL Test in March-April 2001)
(Rural area; LIDAR data, aerial photos and GIS available from the DOT - ITS project)
Tupelo, Mississippi - Airport
(Groundtruth data available)
Auburn, Alabama –
NCAT Highway Test Track
(Accelerated testing; 5 years traffic in one year;
record of fuel and oil consumption accessible
for calculating emissions on ground; in Year 2)
Memphis, Tennessee and South Haven, Mississippi –
I-55, US78, Memphis International Airport
(Heavy truck traffic and aviation traffic; in Year 2 or Year 3)

The University of Mississippi - CAIT Project (Air Quality)
Year 1 Project Goals and Procedures:
Literature review on current remote sensing methods being used and data collected in North America and
Europe. Terrestrial data on air quality in Mississippi identified for groundtruthing.
Three study sites are identified for air quality analysis. Mississippi Highway 6 in Oxford, adjacent to the
University of Mississippi campus, is one site. Airborne LIDAR and color aerial photography will be carried out
for the Oxford area in March 2001. A follow up remote sensing survey is planned using DIAL (Differential
Absorption LIDAR) remote sensing technology for measuring air pollutants.
A second potential site is the Auburn Highway Test Track where 5 years of heavy truck traffic will be
accomplished in one year, starting Fall 2000. A site visit to the test track has been made and the Director of the
test track has agreed for the use of truck fuel and emission data. Applications of available emission models.
The third potential site will be selected on I-55 or US Highway 78 corridors between Memphis, Tennessee and
South Haven region in Northern Mississippi. Tupelo is another candidate site in North Mississippi where
groundtruth data on air pollution are available.
Participation in advisory committee and TRB meetings. Preparation of second year work plan and budget.
Year 2 Project Goals and Procedures:
Collection of available terrestrial air quality data, traffic and climatic data on the selected sites. Collection of
spaceborne data and images and exploratory analysis. Airborne LIDAR data collection over the Auburn test
track. Evaluation of emission models used by the DOT and EPA. Development of artificial neural network and
other advanced nonlinear models to quantify the effects of wind on dispersion of air pollutants.
A state-of-the-art protocol will be developed for air quality analysis using remote sensing LIDAR data.
