Screening Air Dispersion Model SCREEN View is a free software package and is designed for screening level air dispersion modeling. With conservative calculations and simplified input requirements, SCREEN View is ideal for initial screening runs. The modeling system consists of three main components and a set of preprocessing and post-processing programs. The main components of the modeling system are CALMET (a diagnostic three-dimensional meteorological model), CALPUFF (an air quality dispersion model), and CALPOST (a post-processing package).

What is Air Dispersion Modeling?
Air Dispersion Modeling allows us to create a simulation of how atmospheric processes disperse pollutants in the ambient atmosphere using mathematical formulations to provide quantitative air concentration and surface deposition data.
Trinity Consulting Services: Air Dispersion Modeling
For more than 40 years, Trinity Consultants has performed air dispersion modeling for industrial facilities, utilities, and government agencies. Trinity is recognized nationally and internationally for our skills and advanced modeling software/infrastructure, enabling Trinity to formulate and conduct dispersion modeling studies for numerous applications.
Trinity Consultants can assist you with the following:
- Assessing impacts of air emissions from a single site or cumulative sites to demonstrate compliance with ambient air quality standards and other air quality-related values (acid deposition, visibility, regional haze, etc.) utilizing U.S. EPA preferred models (e.g., AERMOD), and beta-version AERCOARE (the marine environment version of AERMOD), and long range screening models such as CALPUFF and SCICHEM
- Assessing impacts of offshore emissions on the air quality of coastal regions using the Offshore and Coastal Dispersion (OCD) model
- Assessing visible plumes, icing, and fogging impacts due to high water-content air emissions using specialized models such as FOG, SACTI, and CALPUFF
- Performing off-site consequence analyses for risk management planning and meeting state and local air toxic modeling requirements using AERMOD and EPA dispersion, fire, and explosion models included in BREEZE Incident Analyst
- Evaluating individual and cumulative human and ecological risk, and performing probabilistic risk analyses using various modeling tools including BREEZE Risk Analyst and other risk modeling tools
- Conducting off-site impact and deposition studies to support litigation activities
- Performing fatal flaw analyses for siting considerations
- Predicting the impact of roadway air emissions with MOVES and AERMOD (EPA is proposing to replace CALINE as a preferred roadway model)
- Conducting regional modeling studies with the Community Multi-scale Air Quality (CMAQ) model and the Comprehensive Air-quality Model with extensions (CAMx, a photochemical model) for regional haze analyses, control strategy evaluations, ozone/PM2.5 impact assessments, and inter-pollutant credit demonstrations in support of nonattainment new source review permitting
- Conducting odor concentration modeling and predicting the effect of different abatement strategies using SCREEN3, AERSCREEN, AERMOD, and CALPUFF
- Analyzing potential risks associated with release of liquefied fuel gas (LFG) and liquefied natural gas (LNG) using BREEZE LFG Fire/Risk and Incident Analyst
- Predicting structural damage and personnel injury from the detonation of high explosives and vapor cloud explosions with BREEZE ExDAM, and illustrating setup and results in powerful 3D graphs and animations
- Processing model-ready meteorological data from surface/upper air observations as well as prognostic meso-scale meteorological models (WRF/MM5) to support to various dispersion models (AERMOD, CALPUFF, CMAQ, CAMx, OCD, etc.)

AERMOD View Introduction AERMOD View is a complete and powerful air dispersion modeling package which seamlessly incorporates the popular U.S. EPA models into one interface: AERMOD, ISCST3, and ISC-PRIME. These models are used extensively to assess pollution concentration and deposition from a wide variety of sources. AERMOD is the next generation air dispersion model designed for short-range (up to 50 kilometers) dispersion of air pollutant emissions from stationary industrial sources. AERMOD is a steady-state plume model that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling, including treatment of both surface and elevated sources, and both simple and complex terrain | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
