Figure 6.14, “Smkinven input and output files for area sources” shows the input and output files for Smkinven for area sources. If importing gridded data, Smkinven reads the AG file; for the annual inventory, Smkinven reads the ARINV file. The ARTOPNT file is used to assign point-source locations to area sources, and the COSTCY file is used to assign time zones to the annual inventory data. Smkinven also uses the inventory data table (INVTABLE), the optional NONHAP exclusions file (NHAPEXCLUDE), and the SCC description file (SCCDESC) if processing area-to-point sources.
Smkinven outputs an annual and average-day inventory emissions file (AREA), a file listing the inventory SCCs (ASCC), a log file (LOGFILE), and a report containing various information about the processed inventory (REPINVEN).
Figure 6.15, “Smkinven input and output files for mobile sources” shows the input and output files for Smkinven for mobile sources. The input files include the country, state and county codes file (COSTCY), the inventory data table (INVTABLE), the raw inventory file (MBINV), and the mobile codes file (MCODES). The NONHAP exclusions file (NHAPEXCLUDE) is optional as is the VMTMIX file.
Smkinven outputs a log file (LOGFILE), an annual and average-day inventory emissions file (MOBL), a file listing the inventory SCCs (MSCC), and a report containing various information about the processed inventory (REPINVEN).
Figure 6.16, “Smkinven input and output files for point sources” shows the input and output files for Smkinven for point sources. The input files include the optional CEM summary file (CEMSUM) created by CEMScan, the country, state and county codes file (COSTCY), the inventory data table (INVTABLE), and the optional NONHAP exclusions file (NHAPEXCLUDE). If importing hour-specific data, the ORIS facility description file ORISDESC is used. The PSTK file provides replacement stack parameters. Day-specific data is read from the PTDAY file, while hour-specific data comes from the PTHOUR file; the PTINV file provides the raw inventory data. For hour-specific data, the SCC description file (SCCDESC) is also needed.
Smkinven outputs a log file (LOGFILE), and optional day-specific inventory (PDAY), and an optional hour-spceific inventory (PHOUR). The annual and average-day inventory emissions are stored in the PNTS file and the PSCC file lists the inventory SCCs. For EMS-95 formatted inputs, an optional temporal profiles file (PTREF_ALT) is output. Finally, the REPINVEN report contains various information about the processed inventory.

-
CHECK_STACKS_YN: [default: Y]Indicates if stack parameter values should be checked for missing or out-of-range values; only checked if
SMK_SOURCEis set to P.-
Y: Check input stack parameters for missing or out-of-range values
-
N: Do not check input stack parameter values
-
-
DAY_SPECIFIC_YN: [default: N]Defines whether to import day-specific inventory data.
-
Y: Import day-specific data
-
N: Do not import day-specific data
-
-
FILL_ANNUAL: [default N]Allows annual data to be filled in with average-day data.
-
Y: Use “Y” when annual emission numbers are blank for some records of the inventory but not all records. The emissions values will be filled in using the average-day emissions field, by multiplying the average-day number by the number of days in the inventory year (365 or 366). This option is useful when some sources have only annual data and some sources have only average-day data. Although the annual number will be filled in using the average-day one, the average-day emissions will be output from SMOKE as a whole. Note that
SMK_AVEDAY_YNshould be set to N in other SMOKE programs when this option has been selected. -
N: Do not fill in annual data based on average-day emissions values.
-
-
FLOW_RATE_FACTOR: [default: 15875 ft3/MMBTU]Used to calculate hourly flow rates from hourly heat input when reading CEM data. If
FLOW_RATE_FACTORis set to zero or unset, then Smkinven will not calculate hourly flow rates. TDetail information is described in Section 2.9.19, “Processing hour-specific CEM data”hourly flow rate (m3/s) = [
FLOW_RATE_FACTOR(ft3/MMBTU) * hourly heat input (MMBTU/hr) * 0.02831 m3/ft3] / 3600 s/hr -
FULLSCC_ONLY: See description in Section 6.2.3.2, “Input Environment Variables”. In this context, this option affects cross-referencing for theARTOPNT,NHAPEXCLUDE, andVMTMIXfiles by preventing left-7 SCC assignments. It also prevents left-2 and left-4 SCC assignments for NHAPEXCLUDE. -
HOUR_SPECIFIC_YN: [default: N]Defines whether to import hour-specific inventory data.

-
-
HOURLY_TO_PROFILE: [default: N]Defines whether to treat the hour-specific inputs as hour-specific temporal profiles.
-
Y: Treat hourly data as temporal profile, and divide each hourly value by value in the daily total column of the file. The values are not renormalized. The resulting hour-specific output file will be recognized by the Temporal program as containing hourly profiles. This setting does not work for input of hour-specific data using CEM format.
-

Y: Read
NHAPEXCLUDEcross-reference file and do not integrate the specified sources. See also Section 2.9.5, “Combine toxics and criteria inventories” for a description of criteria/HAP VOC integration. For all sources that will not be integrated, Smkinven will automatically create additional pollutants in the intermediate inventory file output by the program, based on input HAP pollutants that meet the following conditions in the Inventory Table (INVTABLE) file:-
A "Y" appears in the "Keep" field (of the Inventory Table)
-
A "V" or "T" appears in the "VOC or TOG component" field
-
A "Y" appears in the "Model species" field
-
Something other than "Y" appears in the "Explicit in mechanism" field (e.g., "N" or blank)
The purpose of this operation is described in Section 2.9.5.1.4, “Toxics-CB4, no-integrate”

-
-
SMK_SOURCE: See description in Section 6.2.3.2, “Input Environment Variables” -
SMK_TMPDIR: [default:.]Sets the path for writing temporary files needed when importing the inventory.
-
SMKINVEN_FORMULA: [default: blank]Allows you to specify a formula for computing one or more pollutant values from the values of other pollutants. To use, users should set the value of
SMKINVEN_FORMULAto a double-quote-enclosed string of 512 characters or less, using a comma-delimited list of formulas. No spaces are necessary in the formula list. Only formulas of a specific structure are accepted. Specifically, one of the following:- OUTPUT = INPUT1 + INPUT2
- OUTPUT = INPUT1 - INPUT2
For example, if the formula is set to “PMC=PM10-PM2_5,EXH__PMC=EXH__PM10-EXH__PM2_5”, then Smkinven will compute two new variables: (1) PMC, as the difference between PM10 and PM2.5 and (2) EXH__PMC as the difference between exhaust PM10 and exhaust PM2.5. The pollutant units are taken from the first variable in each formula. The variables used as input in the formula will still be output to the SMOKE inventory file. If the formula is not set, no additional variables will be written to the SMOKE inventory file. An output from one formula may not be used as an input to another formula. In the OUTPUT pollutant name is the same as an INPUT pollutant name from the inventory file, Smkinven will give an error indicating that the second pollutant could not be written (e.g. if computing PMC when PMC is already in the raw inventory data). If INPUT2 is ommitted, an error will also occur. Formulas using multiplication and division are not yet implemented.
-
VELOC_RECALC: [default: N]Defines whether stack velocity is recalculated in order to make the velocity consistent with the reported flow and diameter.
-
Y: Recalculate stack velocity
-
N: Output the input stack velocity
-

-
-
WKDAY_NORMALIZE: [default: Y for EMS-95 input format, N for all other formats]Clarifies the nature of the “average-day” data read in by Smkinven and will impact the Temporal program processing of EMS-95 formatted data of type “AD” and average-day data for all other formats.
-
Y: Average-day emissions input to Smkinven are based on weekday emissions only. In Temporal, these emissions will be adjusted with weekly profiles normalized with weekdays only (Monday through Friday)
-
N: Average-day emissions input to Smkinven are based on all days of the week. In Temporal, these emissions will be adjusted with weekly profiles normalized with all days of the week.
-
-
WRITE_ANN_ZERO: [default: N]Indicates if annual emission values equal to zero should be written to the intermediate inventory file
-
Y: Write zero emission values; this option makes the intermediate inventory file larger but is sometimes necessary when only daily or hourly data is provided and the entries in the annual inventory are dummy values
-
N: Do not write zero values
