AERMOD ViewTM (Gaussian Plume Air Dispersion Model)

AERMOD View is a complete and powerful air dispersion-modeling package, which seamlessly incorporates the following popular U.S. EPA air dispersion models into one integrated interface:


These US EPA air dispersion models are used extensively to assess pollution concentration and deposition from a wide variety of sources.

The AMS/EPA Regulatory Model (AERMOD) is the next generation air dispersion model based on planetary boundary layer theory.

AERMOD utilizes a similar input and output structure to ISCST3 and shares many of the same features, as well as offering additional features.

AERMOD fully incorporates the PRIME building downwash algorithms, advanced depositional parameters, local terrain effects, and advanced meteorological turbulence calculations.

Mathematical Model CALPUFF ViewTM

CALPUFF View provides a complete graphical solution for the CALPUFF modeling system: CALPUFF, CALMET, CALPOST, and their related pre- and post-processors. All three modeling systems are supported by the interface:

 · USEPA Approved Version 5.8  · Version 6  · Version 7

CALPUFF View includes powerful and independent QA tools, stunning report-ready results, ready for technical dispersion reports and a wide range of visualization options.

CALPUFF is a sophisticated model and is used in many modeling scenarios including:

 · Toxic pollutant deposition
 · Visibility assessments
 · Complex terrain
 · Secondary pollutant formation
 · Long range and overwater transport
 · Building downwash

· Costal interaction effects
· Dry deposition
· Fumigation conditions
· Chemical transformation
· Sub-hourly time steps

Risk Planning (Mathematical Models):

·  EcoRisk View is an advanced ecological risk assessment program.
·  SEVEX View is an advanced 3D model of dense gas over complex terrain.
·  SLAB View - Simulation of accidental leaks of denser gases than air.

Other Products Mathematical Model of Simulation: 

·  CCALRoads View is a model for predicting the impacts of pollutants near highways.
·  AERMETView - AERMOD Preprocessor of meteorological data.
