CALPUFF Control File Inputs - Input Group 17
Non-Gridded (Discrete) Receptor Data
Variable Type Description Default Value
(Input Group 17a - General Discrete Receptor Data)
NREC integer Number of non-gridded receptors -
(Input Group 17b - Discrete Receptor Data)
XKM real X coordinate (km) of the discrete receptor on the
meteorological grid
YKM real Y coordinate (km) of the discrete receptor on the
meteorological grid
-
-
ELEV real Ground elevation (m) above mean sea level of the receptor -
ZREC real Height (m) of discrete receptor above the ground 0.0
The variables in Input Group 17b are entered for each of the "NREC" discrete receptors. The data for
each receptor is treated as a separate input subgroup, and therefore, must end with an input group
terminator (i.e., !END!). The format of Input Group 17b is shown below.

Data for each receptor are treated as a separate input subgroup
and therefore must end with an input group terminator.
b
Receptor height above ground is optional. If no value is entered,
the receptor is placed on the ground.
Note that the receptor number is an optional user comment which is outside of the delimiter. The data for
