Input directories, which contain SMOKE input files, are one of the subdirectory types that make up the $SMKDAT directory shown in Figure 3.1, “Basic SMOKE directories: the first three levels of the directory structure” as $SMK_HOME/data. In this section, we provide the structure of these input directories.

Figure 3.3, “SMOKE input files directory structure” shows all of the input directories that stem from $SMKDAT. In the diagram, note how some paths depend on environment variables set in the Assigns file. For example, the INVID environment variable listed in Section 3.2.1, “Example Assigns file” is defined by the user (as we will describe in Chapter 4, How to Use SMOKE) to label the inventory name. This variable is used to build the name of the INVDIR directory as follows:

INVDIR = $SMKDAT/inventory/$INVID

So, if a user decided to label the inventory “nei99”, then the Assigns file would have INVID = nei99 and the INVDIR directory would be $SMKDAT/inventory/nei99. Another example of this in the figure is the SMK_M6PATH directory. The full path depends upon the setting of the MSCEN variable; if MSCEN is set to “case1”, then SMK_M6PATH would be $SMKDAT/run_case1/static/m6.

In some cases, we do not have environment variables associated with a directory name. One example is the $SMKDAT/inventory directory. In these cases, we did not assign variables simply because they were not very useful and we have to limit the number of SMOKE environment variables. Most operating systems have a limit on the number of environment variables (usually 256), so when the variables were not really useful we did not assign them. If desired, you can add environment variables to the Assigns file and/or the set_dirs.scr helper script.

Figure 3.3. SMOKE input files directory structure

In the list below, we describe the purpose of each of these directories, along with the file names and in some cases file descriptions for those files that you may need to change. You can refer to Chapter 8, SMOKE Input Files for more information about each of these files (look under the logical file names). Chapter 4, How to Use SMOKE provides step-by-step instructions on how to create and install each of the files listed.

ge_dat: This directory contains the cross-reference files, profile files, spatial surrogates, and other files that are likely to be shared among multiple cases of processing inventories with SMOKE. The logical file names for files included in this directory are listed here; many physical files could be available in the ge_dat directory for each file type. For example, you may have dozens of surrogate files for different modeling grids and several speciation profiles for different model-mechanism combinations. More detailed descriptions of these files are in Chapter 8, SMOKE Input Files; descriptions of the example files provide with SMOKE are in Section 4.2, “Test case descriptions”.
- BGPRO: The spatial surrogates file biogenics (for computing county-total emissions with Smkmerge).
- SRGPRO_PATH: The location of the spatial surrogates file for nonpoint (stationary area)/nonroad and on-road mobile sources.
- AGREF, MGREF: The spatial cross-reference files for nonpoint (stationary area)/nonroad and on-road mobile sources. These two logical file names can all reference the same physical file.
- ATPRO, MTPRO, PTPRO: The temporal profiles files for nonpoint (stationary area)/nonroad, on-road mobile, and point sources. These three logical file names can all reference the same physical file.
- ATREF, MTREF, PTREF: The temporal cross-reference files for nonpoint (stationary area)/nonroad, on-road mobile, and point sources. These three logical file names can all reference the same physical file.
- B3FAC: The BEIS3.14 normalized emission factors.
- B360FAC: The BEIS3.60 normalized emission factors.
- BIOSEASON: I/O API file indicating which grid cells in a domain are winter and which are summer for biogenics modeling purposes, for each day of the year or episode.
- COSTCY: The country, state, and county information file.
- GRIDDESC: The grid definitions file.
- SRGDESC: The surrogate definitions/description file.
- GSREF, GSPRO, GSCNV: The chemical speciation cross-reference file, speciation profiles file, and pollutant-to-pollutant conversion file (e.g., VOC-to-TOG factors), respectively.
- HOLIDAYS: The dates that SMOKE should process as holidays and the day of the week to use for each date instead of its actual day of the week (the substitute is usually a Saturday or Sunday).
- PROCDATES: The sequential/non-sequential user-specified dates that SMOKE should process.
- PSTK: The point-source replacement stack parameters.
- SCCDESC, SRGDESC, ORISDESC, SICDESC, MACTDESC, NAICSDESC: The descriptions of each known SCC, surrogate code, ORIS ID, SIC code, MACT code, and NAICS code.
inventory: The location of all inventory files for each inventory case (as defined by the $INVID environment variable in an Assigns file), land use data, and other data.
- $INVID: This directory name depends on the name given to the inventory in the Assigns file. (This is the case for any directory name in the figure that is preceded with “$” to indicate that it is an environment variable.) The files in the subdirectories are specific to your inventory files and modeling case. This directory contains subdirectories for each of the major source categories by default:
  - area: Contains the nonpoint or stationary area inventories. Optionally, it may contain nonroad mobile inventories. Can include any inventory that will be processed as a SMOKE area source (e.g. criteria, particulates, and/or toxics inventories). Files should include:
    
    ARINV (raw area-source inventory file). If this is a list file, the files listed within it should also be included in this directory.
    
    ARDAY (raw day-specific area-source inventory file). If this optional file is a list file, the files listed within it should also be included in this directory.
    
    ARHOUR (raw hour-specific area-source inventory file). If this optional file is a list file, the files listed within it should also be included in this directory.
    
    GCNTL (control packet file). The growth and control packet files for each growth or control scenario. The default naming scheme for these files is described in the default SMOKE scripts.
  - biog: Contains the gridded BELD3 and/or BELD4 land use data. These files are listed in the Assigns files as BELD3_A, BELD3_B, and BELD3_TOT for BEIS3.14. This directory could optionally contain the gridded BELD4 land use data if proceessing using BEIS3.60); this file is listed in the Assigns file as BELD4.
  - mobile (MOVES): Contains the on-road mobile inventory and other on-road mobile-specific input files. Files should include:
    
    GCNTL (control packet file). The growth and control packet files for each growth or control scenario. The default naming scheme for these files is described in the default SMOKE scripts.
    
    MBINV (raw on-road mobile-source inventory file). This is a FF10 activity inventory format for VMT, SPEED and VPOP inventory data. EAA - put in a link to input file description.. If this is a list file, the files listed within it should also be included in this directory.
    
    MCXREF (mobile-source county cross-reference). For MOVES modeling only, contains the representative county assignments (see Section 2.8.4.6, “Representative Counties” for an explanation of representative counties).
    
    MEPROC (mobile-source processing file). For MOVES modeling only, contains the pollutants to be modeled by MOVES by the emission processes (e.g., exhaust, evaporative, break and tire wear).
    
    SPDPRO (speed profiles file). For MOVES modeling only, contains the optional weekday/weekend hour-specific speed profiles for use of MOVES on-roadway emission rates.
  - point: Contains the point-source inventory and other point-specific input files. Files should include:
    
    CEMSUM (CEM summary file). When processing CEM data, this file contains a summary of a year’s worth of CEM data and is produced by CEMScan.
    
    GCNTL (control packet file). The growth and control packet files for each growth or control scenario. The default naming scheme for these files is described in the default SMOKE scripts.
    
    PELVCONFIG (elevated-source selection configuration file). When using the Elevpoint program to select elevated and PinG sources, this file is required to specify the selection criteria.
    
    PTDAY (raw day-specific point-source inventory file). If this optional file is a list file, which is typically the case, the files listed within it should also be included in this directory.
    
    PTHOUR (raw hour-specific point-source inventory file). If this optional file is a list file, which is typically the case, the files listed within it should also be included in this directory.
    
    PTINV (raw point-source inventory file). If this is a list file, the files listed within it should also be included in this directory.
- other: Contains files that are associated with the various inventories, but which may be shared by more than one source category. These files are:
  - ARTOPNT (area-to-point file). Contains the area-to-point assignments by SCC with the point locations for each county in which a SMOKE area source will be assigned to point locations.
  - INVTABLE (inventory table file). Contains a list of the valid inventory pollutants and whether or not emissions associated with each pollutant should be kept when reading the inventory files, among other purposes.
  - NHAPEXCLUDE (non-HAP exclusions file). Contains the SCCs that will be excluded from a NONHAPVOC or NONHAPTOG calculation when integrating toxics and criteria inventories.
  - REPCONFIG (report configuration file). Contains instructions used by Smkreport to configure reports. The SMOKE installation includes only the REPCONFIG files for the default reports included with the SMOKE default scripts.
met/run_$METSCEN: This directory contains the meteorology files that are needed for running (1) biogenic emissions; (2) on-roadway and off-network mobile sources with MOVES using gridded, hourly meteorology data; or (3) point sources for the CMAQ model. Meteorology data are required in all of these cases. SMOKE can use output files from CMAQ’s MCIP and MCIP2 meteorology processors or from the Meteorology Coupler (MCPL) processor. SMOKE automatically checks for the different variable names that may be used for the same meteorology data in the different file formats. See Section 8.8, “Meteorology Files” for more information about the meteorology data needed by SMOKE.
