Hagler, G. AND H. Brantley. Near-source air quality in rail yard environments – an overview of recent EPA measurement and modeling findings. Presented at Atlanta Rail Yard Study (ARYS, Atlanta, GA, September 10, 2014.
Impact/Purpose:
This is a product for ACE Task 019 - providing an overview of field and modeling research related to near-source air quality and rail yard emissions.
Description:
This presentation will providing a summary of field measurements conducted in areas surrounding two major rail yards as well as modeling simulations of rail yard emissions dispersion. The Cicero Rail Yard Study (CIRYS) was recently released to the public and includes mobile and stationary monitoring, as well as inverse modeling of the stationary measurements. The Atlanta Rail Yard Study (ARYS) involved extensive speciation of the air pollution mixture surrounding a major rail yard area, utilizing an expanded mobile monitoring approach. The computational fluid dynamics modeling study complemented the field measurements, investigating how rail yard emissions dispersion is affected by the surrounding terrain and wind direction.
