The steps you need to take to use BEIS2 for your modeling case are:
Ensure that the land use file has been created and properly installed.
See Section 4.4.9.2, “Installing or changing spatial input files”, step 4) for more information on creating and installing the land use data.
Ensure that the meteorology data are correct.
See Section 4.4.9.2, “Installing or changing spatial input files”, step 5) and Section 4.4.17, “Change meteorology data” for more information on creating and installing the meteorology data.
Ensure that summer and/or winter emission factors are in place.
The BFAC and BFAC_W files are installed by SMOKE and do not need to be changed, so it is very unlikely that these files will not be in their
GE_DAT
Set up your BEIS2 run script.
To set up your BEIS2 run, copy the example BEIS2 run script listed in Section 4.2.3, “Example script files and their purposes” and reset the script settings. The settings that you may need to reset are as follows (see Chapter 6, SMOKE Core Programs for all program options):
RUN_METSCAN: Set to Y if you need to use the BIOSEASON file (see Section 4.4.9.2, “Installing or changing spatial input files”, step 6).
Rawbio options
Tmpbio options
Smkmerge options - this program is used to create state/county totals and/or to change units for CMAQ from moles/hr (output by Tmpbio) to moles/s. Depending on the purpose for running Smkmerge in your script, adjust the Smkmerge options accordingly. Please note that you cannot create gridded outputs in moles/s and state/county totals in tons/day in a single run.
If creating state/county totals, make sure the AREA_SURROGATE_NUM setting is set to the cell-area surrogate number in your BGPRO file.
SPC_OVERRIDE: May be needed in some cases (see Section 4.2.4, “Script settings”)
Run the BEIS2 script.
