CALPUFF Control File Inputs - Input Group 14
Area Source Parameters
Variable Type Description Default Value
(Input Group 14c - Vertex Data for Area Sources with Constant Parameters or
Emissions Scale Factors)
SRCNAM
character*12
Source name, used to coordinate inputs in Subgroups
b,c,d
-
XVERT
real
X coordinates (km) of each vertex of the area source on
the meteorological grid
-
YVERT real Y coordinate (km) of each vertex of the area source on
-
the meteorological grid
The variables in Input Group 14c are entered for each of the "NAR1" area 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 14c is shown below.
