Atmospheric Dispersion Modeling Expert Witnesses

Atmospheric dispersion models are also known as atmospheric diffusion models, air dispersion models, air quality models, and air pollution dispersion models. An atmospheric dispersion modeling expert witness typically has a background in meteorology, regulatory requirements, mathematics, and/or atmospheric dispersion.
Based on mathematical formulations, atmospheric dispersion modeling is the simulation of how air pollutants disperse in the ambient atmosphere. Air quality models are used to determine compliance with regulatory requirements including the National Ambient Air Quality Standards (NAAQS). As examples, dispersion models are used to estimate air pollutants emitted from industrial plants, traffic emissions and accidental chemical releases.
Dispersion models vary, but all require input of data that may include:
- Meteorological conditions
- Source term (the concentration of toxins)
- Emissions or release parameters (e.g., source location, type of source, velocity, exit temperature)
- Terrain elevations at the source and receptor locations
- The location and size of obstructions (such as buildings)
Litigation support by an atmospheric dispersion modeling expert could include analysis, deposition, expert report, and expert witness testimony at a trial. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a qualified expert with prior expert witness experience. In addition, clients may seek an industry expert for pre-litigation consulting work. An expert witness needs to not only have expertise in the subject, but must also possess the ability to explain evidence to a juror.
