CALPUFF Control File Inputs - Input Group 2
Technical Options
Variable Type Description Default Value
MGAUSS integer Control variable determining the vertical
distribution used in the near field
(0 = uniform, 1 = Gaussian)
MCTADJ integer Terrain adjustment method
0 = no adjustment
1 = ISC-type of terrain adjustment
2 = simple, CALPUFF-type of terrain adjustment
3 = partial plume path adjustment
MCTSG integer CALPUFF subgrid scale complex terrain module
(CTSG) flag
(0 = CTSG not modeled, 1 = CTSG modeled)
MSLUG integer Near-field puffs modeled as elongated "slugs"
(0 = no, 1 = yes)
MTRANS integer Transitional plume rise modeled
(0 = only final rise computed, 1 = transitional rise
computed) Note: Transitional plume rise is
always computed for sources subject to building
downwash effects.
MTIP integer Stack tip downwash modeled
0 = no (i.e., no stack tip downwash)
1 = yes (i.e., use stack tip downwash)
MRISE interger Method used to compute plume rise for point
sources not subject to downwash
1 = Briggs plume rise
2 = Numerical plume rise
MBDW integer Method used to simulate building downwash
1 = ISC method
2 = PRIME method
