PENETRATED SOURCE CONTRIBUTION TO CONCENTRATION CALCULATIONS IN THE CBL

The penetrated source concentration expression is a simple Gaussian form (for both vertical and horizontal plume distributions). The contribution from the horizontal plume state is given by the following:

The total concentration for the terrain responding state has the form of eq.(76) with z_r replaced by z_p .

The dispersion coefficients (_yp & _zp ) resulting from the total turbulence (ambient, buoyancy induced & building induced) are calculated using eq.(86).
