The Decay Term (D)

The Decay Term is a simple method of accounting for pollutant removal by physical or chemical processes. It is of the form:

D=exp(-psi x/us)    for psi > 0   (36)

D=0                for psi = 0   (37)

where:

psi= the decay coefficient (s-1) (a value of zero means decay is not considered)

x= downwind distance (m)

For example, if T1/2 is the pollutant half life in seconds, the user can obtain y from the relationship:

psi=0.693/T1/2          (38)

The default value for psi is zero. That is, decay is not considered in the model calculations unless y is specified. However, a decay half life of 4 hours (y = 0.0000481 s-1) corresponds to SO2 when modeled.
