Tmpbeis3 input and output files

Figure 6.25, “Tmpbeis3 input and output files” shows the input and output files for the Tmpbeis3 program. The input files include the gridded, normalized biogenic emissions from Normbeis3 (B3GRD) and, if BIOSW_YN = Y, then a gridded, seasonal switch file output from Metscan is required (BIOSEASON). The biogenic speciation profiles are read from the GSPRO file and the GRID_CRO_2D contains the latitude and longitute for each grid cell. Tmpbeis3 reads surface pressure and radiation/cloud data from MET_FILE1 and optionally from MET_FILE2 if BIOMET_SAME = N.

Tmpbeis3 outputs gridded, speciated, hourly biogenic emissions files in moles/hour (B3GTS_L) and tons/hour (B3GTS_S). The program also outputs an execution log file (LOGFILE).

6.17.3.1. Input Files

File Name Format Description
B3GRD I/O API NetCDF Gridded, normalized biogenic emissions, output from Normbeis3
BIOSEASON (optional) I/O API NetCDF Gridded seasonal switch file containing daily data, with “0” meaning use winter normalized emissions and “1” meaning use the summer normalized emissions, produced by Metscan
GSPRO ASCII Speciation profiles file (do not use the same profiles used in SMOKE-BEIS2; use profile named “BV309)
GRID_CRO_2D I/O API NetCDF Meteorology file containing latitude and longitude coordinates for each grid cell
MET_FILE1 I/O API NetCDF Meteorology file containing temperature and surface pressure data and possibly radiation/cloud data as well (see BIOMET_SAME environment variable)
MET_FILE2 (optional) I/O API NetCDF Meteorology file containing radiation/cloud data if not in MET_FILE1

6.17.3.2. Input Environment Variables

  • BG_CLOUD_TYPE: [default: 1]

    Specifies which meteorological data to use.

    • 1: Use RGND or RSD (solar radiation reaching the ground) from MM5 to calculate PAR. No other options are supported at this time.

  • BIOG_SPRO: [default: BV309]

    Specifies the speciation profile for biogenic emissions from GSPRO.

  • BIOMET_SAME: [default: N]

    Defines whether the radiation/cloud data are in the same file as the temperature data (MET_FILE1) or in a different file (MET_FILE2).

  • BIOSW_YN: [default: Y]

    Indicates whether to use a gridded seasonal switch file.

    • Y: Use gridded seasonal switch file BIOSEASON

    • N: Use environment variable SUMMER_YN to determine season

  • OUTZONE: See description in Section 6.11.3.2, “Input Environment Variables”

  • PRES_VAR: [default: PRSFC]

    Specifies the variable name for surface pressure data to extract from MET_FILE1.

  • RAD_VAR: [default: RGRND]

    Specifies the variable name for radiation/cloud data to extract from either MET_FILE1 or optional MET_FILE2.

  • SUMMER_YN: [default: Y]

    Indicates whether summer or winter normalized emissions should be used; only used when BIOSW_YN is N.

    • Y: Use summer normalized emissions

    • N: Use winter normalized emissions

  • TMPR_VAR: [default: TA]

    Specifies the variable name for temperature to extract from MET_FILE1.
