As also discussed in Section 5.4, the AERMOD urban option (URBANOPT) should be selected

for urban applications, regardless of whether the meteorological measurement site is located in

an urban setting. This is due to the fact that the limited surface meteorological measurements

available from the meteorological measurement program (even with measured turbulence) will

not adequately account for the meteorological characteristics of the urban boundary layer

included in the AERMOD urban algorithms.

 

4.0 TERRAIN DATA AND PROCESSING

4.1 MODELING SOURCES WITH TERRAIN-FOLLOWING PLUMES IN SLOPING

TERRAIN (01/09/08)

Under the regulatory default mode (DFAULT option on the MODELOPT keyword), for all

situations in which there is a difference in elevation between the source and receptor, AERMOD

simulates the total concentration as the weighted sum of 2 plume states (Cimorelli, et al., 2004):

1) a horizontal plume state (where the plume’s elevation is assumed to be determined by release

height and plume rise effects only, and thereby allowing for impingement if terrain rises to the

elevation of the plume); and, 2) a terrain-responding plume state (where the plume is assumed to

be entirely terrain following).
