Air Dispersion Modeling


Air dispersion modeling uses information about sources and meteorological conditions to calculate how a pollutant moves through the atmosphere and what the pollutant concentration is at specific points.


AERMOD View

Our most commonly used air dispersion model and is applicable to a wide range of buoyant or neutrally buoyant emissions up to a range of 50km. Also suitable for complex terrain and urban dispersion scenarios.

CALPUFF View

A non-steady state Gaussian puff model, suitable for long range transport, atmospheric chemistry, visibility and scenarios with complex wind fields, such as coastal and complex terrain areas.

CALRoads View

A traffic dispersion model specifically designed for modeling emissions from vehicles. CALRoads can model timed intersections, parking lots and account from traffic patterns.

AERSCREEN View

A screening-level air quality model based on the US EPA AERMOD model which estimates worst-case ground level concentrations for a single source.

AUSTAL View

A Lagrangian particle tracer model. Widely used in Germany, AUSTAL is capable of modeling complex wind fields and transient behavior.
