Data for Dispersion at the Edges of Near-Road Barriers

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: August 02, 2025 | Last Modified: 2020-11-30
The data is from a wind tunnel study conducted to examine the dispersion of traffice-related emissions at the edges of near-road noise barriers. The data were collected in the EPA's meteorological wind tunnel using a hydrocarbon tracer to simulate emissions from a roadway. The data are presented as normalized concentration distributions (as described in the accompanying paper) for a number of different near road noise barrier configurations.
