6.2.2 Indirect Source Contribution to Concentration Calculations in the CBL
The concentration contribution from the horizontal state of the indirect source is calculated as follow:
The height of the indirect source rj is calculated from eq. (75). The total concentration for the terrain responding state has the form of eq.(74) with zr replaced by zp .
The dispersion coefficients (y ,z1 & z2 ) resulting from the total turbulence (ambient, buoyancy y z1 z2 induced & building induced) are calculated using eqs. (85) and (98) thru (103). The height of the indirect plume is given by the following expression:
h is calculated from eq. (118). The aj‚Äôs in eq. (75) are calculated from eq. (72).
