Air Dispersion Modeling
Air Dispersion Modeling is at the heart of what we do here at our Singapore offices in BroadTech Engineering.
We can perform some of the most complex and precise Air Dispersion Modeling (ADM) simulations using state-of-art emission estimation techniques and computer modeling software.
Based on your client-specific modeling requirement and site conditions, our team of professional and experienced CFD simulation consultants will be able to provide you an accurate simulation of air pollutant dispersion using one of the USEPA recommended air dispersion modeling systems.
*The air dispersion modeling systems that we use are models that are officially recommended and preferred by USEPA
Uses of Air Dispersion Modeling (ADM)
Air dispersion modeling is carried out for several purposes, such as
- Environmental Impact Assessment (EIA)
- Pollution Control Study
- The large-scale urban planning of built environment base on data from Airflow modeling.
Dispersion modeling is most often used as part of the air permitting process when a company plans to construct or modify an industrial facility. It is also useful for emergency planning and capital planning
What is Air Dispersion Modeling?
Air dispersion modeling is a key concept in environmental regulations. It is the process of estimating air pollutant concentration that results from an air emission source.
This takes into account analysis inputs and factors such as Source parameters, Meteorological conditions, and Topography of the area under study
Initially performed with manual numerical calculations in the early days, modern air dispersion modeling today is facilitated with powerful engineering simulation software tools that can perform thousands of calculations in minutes.

Air Dispersion Modeling Scenarios
The Types of air dispersion model and the air quality modeling scenarios that it can simulate includes
1. AERMOD Air Dispersion Modeling System
AERMOD is used for air dispersion modeling of most near airfield industrial scenarios.
It is a steady-state plume simulation modeling system, that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts.
This includes treatment of both surface and elevated sources, as well as geographical terrains which are both simple and complex.
The AERMOD air dispersion modeling system consists of various input data processors, such as
1. AERMET
AERMET is a meteorological data preprocessor that accounts for air dispersion based on turbulence at planetary boundary layer structure and scaling concepts. AERMET is a regulatory component of the AEROMOD modeling system
2. AERSCREEN
AERSCREEN is a screening version of AERMOD. It is used for worse case screening analysis
3. AERMAP
AERMAP is a terrain data preprocessor that incorporates complex terrain using USGS Digital Elevation Data. AERMAP is a regulatory component of the AEROMOD modeling system
4. BPIPPRIM
BPIPPRIM a multi-building dimensions program which uses the GEP technical procedures for PRIME applications.
5. AERSURFACE
AERSURFACE is a surface characteristics preprocessor used for input parameter into AERMOD air dispersion modeling
2. CALPUFF Air Dispersion Modeling System
CALPUFF is for Air Dispersion situations when the source is greater than 50km from the area of concern study
It is a non-steady-state, Multi-layer, Multi-species puff dispersion model that simulates the effects of time- and space-varying climatic conditions on pollution transport, transformation, and removal.
CALPUFF is equipped with computation algorithms which can be applied to
3. BLP
BLP is a Gaussian plume dispersion model specifically adapted to solve unique air dispersion modeling challenges associated with to industrial emission sources, such as aluminum reduction industrial plants where the environmental effects of plume rise and downwash from stationary line sources are critical.
4. CALINE3
CALINE3 is a steady-state Gaussian dispersion modeling system specifically designed to evaluate air contaminant concentrations at receptor locations downwind of highways located in relatively simple geographical terrain.
In practice, CALINE3 is integrated into the more refined CAL3QHC and CAL3QHCR air dispersion models.
5. CAL3QHC/CAL3QHCR
CAL3QHC is a CALINE3 based CO model with queuing and hotspot computation and with a traffic simulation model to calculate delays and queues that occur at signalized intersections.
CAL3QHCR is a more evolved version built based on CAL3QHC that requires an input of local meteorological data.
6. DEGADIS
Dispersion modeling of industrial emission of dense gases that slumps and disperse
7. Puff Models
Accidental releases from tank rupture or other equipment failures
8. Regional Scale Models
Regional scale models where the model is used to study and evaluate pollutant impact for the entire metropolitan area
