Air Dispersion Modeling

How To Choose - Software Solutions

Air dispersion modeling uses information about sources and meteorological conditions to calculate how a pollutant moves through the atmosphere and what the pollutant concentration is at specific points

AERMOD View

AERSCREEN View

Gaussian Plume Air Dispersion Model AERMOD View
AERMOD View is 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.  In addition to more straight forward cases, AERMOD is also suitable for complex terrain and urban dispersion scenarios.

ARTM View

AUSTALView

Atmospheric Radionuclide Transport Model
ARTM View
ARTM View is an ergonomical and intuitive graphical user-interface for the German Federal Office for Radiation (BfS) ARTM model. The ARTM model (Atmospheric Radionuclide Transport Model) calculates the dispersion and deposition of released airborne radioactive materials in the atmosphere.
