Atmospheric Dispersion Models
1) Gaussian Model
2) Puff Model
3) MUC Model

Gaussian Model• The Gaussian Model is
one of the most widely used models in the world to study dispersion phenomena, notably by the EPA (Environmental Protection Agency). This model estimates pollutant concentrations at any point in space based on various factors:
1. Wind Speed & Direction
2. Atmospheric Stability3. Mixing Height4. Temperature
Gaussian Dispersion Plume

Puff Model
• The Puff Model was designed to simulate instantaneous releases into the atmosphere.
This model is used to predict the impact of an accident (tanker truck, holding tank leak or broken pipeline) to allow effective emergency planning.

MUC Model
• The MUC (Montreal Urban Community) model comprises the four formulae specified in MUC By-Law 90 regarding the atmospheric dispersion of gaseous contaminants.

Plume Rise• Polair© 4.2 takes in account the plume
rise elevation by correcting the value of the stack height. In order to effectively evaluate this height, 3 models can be used:
1. U.S. Environmental Protection Agency (EPA)
2. Holland3. Montreal Urban Community (MUC)
