4.1.4 Potential Temperature Profiling in the Interface
Primarily for use in plume rise calculations, AERMOD develops the vertical profile of potential temperature from its estimate of the temperature gradient. First the model computes the potential temperature at the reference height for temperature (i.e., zTref ) and from the reference temperature corrected to sea level pressure such that
and Z SB is the stack base height above mean sea level averaged over all sources. Then for both the CBL and SBL the potential temperature is calculated as follows:
Note that for z < zTref , z < 0.
