CALPUFF Control File Inputs - Input Group 16
Volume Source Parameters
The variables in Input Group 16b are entered for each of the "NVL1" volume sources. The data for each
source is treated as a separate input subgroup, and therefore, must end with an input group terminator
(i.e., !END!). Note that the source number is an optional user comment which is outside of the delimiter
containing the required source data. The data for each source must follow an opening delimiter and "X=".
The data for each source is followed by a closing delimiter and an input group terminator.
The format of Input Group 16b for a simulation with eight species is shown below.

Data for each source are treated as a separate input subgroup
and therefore must end with an input group terminator.
b
An emission rate must be entered for every pollutant modeled.
Enter emission rate of zero for secondary pollutants that are
modeled, but not emitted. Units are specified by IVLU
(e.g. 1 for g/s).
