High Resolution Air Quality and Health Risk Modeling of Air Pollution in 
a Large Megacity in the U.S.
Dr. Sarav Arunachalam (The University of North Carolina at Chapel Hill, 
Estados Unidos)
En colaboración con ChimSur Webinars

Air Pollution Exposure to PM2.5and NO2 is associated with hundreds and 
sometimes thousands of annual premature mortalities in megacities.  
Current air quality and health impact assessment tools provide 
county-wide estimates but are inadequate for assessing health benefits 
at neighborhood scales, especially for evaluating policy options related 
to energy efficiency or climate goals. This presentation introduces 
Tract-level Air Pollution Policy Assessment Tool for New York City 
(TRAPPA-NYC), a new high resolution web-based modeling tool that 
integrates two reduced-form modeling tools to models changes in 
emissions and associated air quality and monetized health risks at a 
census tract scale for New York City. This easy-to-use interactive tool 
empowers users to rapidly model specific policy scenarios and quantify 
health benefits in the support of policy-making to protect public health 
and supports modeling both PM2.5 and NO2. Recent advances to the tool 
that focuses on better characterization of regional-scale transport as 
well as local-scale processes for NO2 will be discussed, along with 
application of specific policy scenarios for transportation and energy 
efficiency measures. We have also expanded this tool to other large 
cities including Atlanta and Dallas Fort-Worth, and potential 
consideration for adapting this tool to other cities in South America 
will be discussed.

Dr. Arunachalam, Deputy Director and Research Professor with the UNC 
Institute for the Environment and UNC Gillings School of Public Health’s 
Department of Environmental Sciences and Engineering. He directs the 
EPA-funded Center for Community Modeling and Analyses System (CMAS) to 
provide modeling support for a global user community, and the U.S. DOT 
funded Center of Excellence on Aviation Emissions to study aircraft 
emissions and their impacts on the environment. Dr. Arunachalam’s 
interests and expertise are in emissions and multi-scale air quality 
modeling with a focus on atmospheric chemistry, source apportionment and 
health risk assessment. His work has been recognized by the U.S .EPA and 
U.S. DOT with multiple awards, and he is a U.S. nominee for multiple 
committees on the ICAO Committee on Aviation Environmental Protection 
(CAEP).  He received his Ph.D. in Chemical Engineering from Rutgers, the 
State University of New Jersey in 1998.

¡¡Les esperamos!!
