Figure 6.7. Met4moves input and output files

Met4moves input and output files

Figure 6.7, “Met4moves input and output files” shows the input and output files for the Met4moves program. The input files are the Grid Description File from MCIP(GRIDDESC), the Surrogate Description file (SRGDESC), the MCIP List of Meteorology File (METLIST), and the reference county cross-reference file (MCXREF).

Met4moves outputs datasets for SMOKE that contain the daily gridded min/max temperatures and averaged RH. Met4moves outputs for MOVES datasets that provide all (min/max) temperature combinations for a reference county, reflecting all min/max combinations for all inventory counties in that county group. The associated RH values are also included in these datasets. In addition, the datasets include the 24-h diurnal profiles needed for the RPP emission process, and contain user-specified temperature increments for use by MOVES.

6.7.3.1. Input Files

File Name Format Description
COSTCY ASCII Country, state, county codes file, with time zones
GRIDDESC ASCII Modeling Domain Grid Description File
MCXREF ASCII Reference county cross-reference file; NOTE: The list of counties in the MCXREF file used by Met4moves must match the list of inventory counties used by SMOKE
METLIST ASCII A list of meteorology files containing temperature, mixing ratio, and surface pressure data created by Metcombine
MFMREF ASCII Reference county fuel monthcross-reference file; NOTE: The list of counties in the MFMREF file used by Met4moves must match the list of inventory counties used by SMOKE
SRGDESC ASCII Surrogate Description File
Surrogate File(s) ASCII Surrogate file(s) selected by SRG_LIST

6.7.3.2. Input Environment Variables

  • STDATE: [default: 0]

    This environment variable sets the overall episode start date: Julian format (YYYYDDD) for Movesmrg.

  • ENDDATE: [default: 0]

    Sets the overall episode end date; Julian format (YYYYDDD).

  • ENDTIME: [default: 230000]

  • PD_TEMP_INCREMENT: [default: 5]

    Defines the temperature increment (in deg. F) for RPD lookup table to create combinations of min/max temperature bins

  • PH_TEMP_INCREMENT: [default: 5]

    Defines the temperature increment (in deg. F) for RPH lookup table to create combinations of min/max temperature bins

  • PV_TEMP_INCREMENT: [default: 5]

    Defines the temperature increment (in deg. F) for RPV lookup table to create combinations of min/max temperature bins

  • PP_TEMP_INCREMENT: [default: 10]

    Defines the temperature increment (in deg. F) for RPP lookup table to create combinations of min/max temperature bins

  • MIN_NO_RH_BY_TEMPBIN: [default: 1]

    Defines the minimum number of data point for computing averaged RH by tempearature bin

  • SPECIFIC_HUMIDITY_YN: [default: N]

    Defines whether compute specific humidity instead of relative humidity

  • SRG_LIST: [default: N]

    Specifies the code(s) of the spatial surrogate(s) to be used in selecting the grid cells for the county (example: setenv SRG_LIST '100,230').

  • SRGPRO_PATH: [default: N]

    Defines the location of spatial surrogate files.

  • TEMP_BUFFER_BIN: [default: 0.0]

    Defines the temperature buffer value (°F). This value will allow Met4moves to expand the min/max temperature range for MOVES RPP processing. If TEMP_BUFFER_BIN is set to 10.0, the original max temperature which is 90.0°F will be treated as 100.0°F, and minimum temperaure (=30°F) will be treated as 20.0°F internally in Met4moves.

  • TVARNAME: [default: TEMP2]

    Specifies the variable name for the temperature to extract from the Met4moves output file (MOVES_OUTFILE).
