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.
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.
A traffic dispersion model specifically designed for modeling emissions from vehicles. CALRoads can model timed intersections, parking lots and account from traffic patterns.
A screening-level air quality model based on the US EPA AERMOD model which estimates worst-case ground level concentrations for a single source.
A Lagrangian particle tracer model. Widely used in Germany, AUSTAL is capable of modeling complex wind fields and transient behavior.
