Near-Source Modeling Updates: Building Downwash & Near-Road
Heist, D. Near-Source Modeling Updates: Building Downwash & Near-Road. UK-US meeting on Air-Quality Modelling & Exposure Science, Kings College, London, UK, September 29 - 30, 2016.
The National Exposure Research Laboratory (NERL) Computational Exposure Division (CED) develops and evaluates data, decision-support tools, and models to be applied to media-specific or receptor-specific problem areas. CED uses modeling-based approaches to characterize exposures, evaluate fate and transport, and support environmental diagnostics/forensics with input from multiple data sources. It also develops media- and receptor-specific models, process models, and decision support tools for use both within and outside of EPA.
The presentation describes recent research efforts in near-source model development focusing on building downwash and near-road barriers. The building downwash section summarizes a recent wind tunnel study, ongoing computational fluid dynamics simulations and efforts to improve model algorithms used in AERMOD. The section on near-road barriers discusses wind tunnel and field studies, summarizes work on the effects of vegetative barriers.
