In Gaussian Dispersion Equation?

The Gaussian air pollutant dispersion equation (discussed above) requires the input of H which is the pollutant plume's centerline height above ground level—and H is the sum of H_s (the actual physical height of the pollutant plume's emission source point) plus ΔH (the plume rise due to the plume's buoyancy).

What is the Gaussian plume equation?

By making the assumption that the flow is steady and that the advective term along wind is much greater than the eddy diffusion along wind there is an analytical solution: the so called gaussian plume model solution, which is described by the following equation: C(x,y,z)=\frac{Q}{2\pi u \sigma _y \sigma _z}\exp\left(-\ ...

What are four types of dispersion models?

Section 5 - Page 1: Types of dispersion models

We have the MM5 model, the WRF, and the GFS, for example. There are many kinds of dispersion models, as well. We'll focus primarily on the Gaussian model, which assumes a "normal distribution" and is the most common type of model used.
