Line Source Parameters
Variable Type Description Default Value
HTL real Release height (m) -
ELEVL real Base elevation (m) -
QL real Emissions rate (g/s) of each pollutant
-
The variables in Input Group 15b are entered for each of the "NLINES" line sources. The data for each
line is treated as a separate input subgroup, and therefore, must end with an input group terminator (i.e.,
!END!). Note that the line number is an optional user comment which is outside of the delimiter
containing the required source data. The data for each line must follow an opening delimiter and "X=".
The data for each line is followed by a closing delimiter and an input group terminator.
The format of Input Group 15b for a simulation with eight species is shown below.

a
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 ILNTU
(e.g. 1 for g/s).
