The AERMOD air dispersion model allows users to input time-varying concentration data to represent background sources to be added to the model’s calculations. This can be done by directly adding background concentrations to modeled pollutant concentrations or, in the case of nitrogen dioxide (NO2), by adding background ozone or NOx concentrations to assist in estimating how much NO2 is formed through chemical transformation.

The Graphical Options within Lakes Software’s wide range of commercial products give users the customization options that modelers need. These options are accessed via buttons on either the main toolbar or Annotation Toolbar.
