CALPUFF and Postprocessors

Table G-21 (Continued)
CALPOST Control File Inputs - Input Group 1
General Run Control Parameters
Variable Type Description Default
METRUN
integer
Option to run all periods in CALPUFF file (0,1)
0
0 = no, run the period defined by ISYR, ISMO, ISDY,
ISHR, and NHRS
1 = yes, run all periods found in the file instead of any
period defined by ISYR, ISMO, ISDY, ISHR, and NHRS
ISYR
ISMO
integer
integer
Starting year of data to process (four digits)
Starting month a
-
-
ISDY
integer
Starting day a
-
ISHR
integer
Starting hour a (0-23). Uses ending hour convention (e.g.,
-
NHRS
integer
Hour 1 refers to the period from 0:00 - 1:00).
Number of hours to process a
-
NREP
integer
Process every "NREP th "hour of data
1
1 = process every hour
2 = process every 2nd hour
ASPEC
character*12
5 = process every 5th hour
Name of "species" to process b
-
ILAYER
integer
Code indicating layer of concentrations (always "1" when
1
processing concentrations from CALPUFF, "-1" for dry
deposition fluxes, "-2" for wet deposition fluxes, and "-3"
for total deposition fluxes)
A
real
Multiplicative scaling factor applied to modeled
0.0
concentrations or deposition fluxes (not applied if
A = B = 0.0)
B
real
Additive factor applied to modeled concentrations or
0.0
deposition fluxes (not applied if A = B = 0.0)
LBACK
logical
Add background concentrations/deposition fluxes from
F
external file
a Used only if METRUN = 0.
b Sample values of ASPEC: SO2, SO4, NOX, HNO3, NO3. For visibility calculations, the species name must be entered as VISIB, which is
not a species name actually used in the CALPUFF run: the species included in the visibility calculations are selected by the LVSO4, LVNO3,
etc. parameters.
