Figure 4.11, “Mrgpt input and output files” shows the input and output files for the Mrgpt program. The input files are a list of the logical file names for the speciated hourly emissions files from Smkmerge to be merged (FILELIST_INLN) and a list of the logical file names for the ASCII elevated output files from Elevpoint to be merged (FILELIST_STACK). The program outputs a log file (LOGFILE), a merged specated hourly emissions file (OUTFILE_INLN), a merged ASCII elevated output file (OUTFILE_STACK), and if merging different days, a report file (REPMRGGRID).
| File Name | Format | Description |
|---|---|---|
FILELIST_INLN |
ASCII | List of logical file name for hourly speciated I/O API NetCDF files; this file cannot contain the full paths and file names. Users should
make sure that the logical file names that appear in FILELIST_INLN are defined prior to running Mrgpt.
|
FILELIST_STACK |
ASCII | List of logical file name for ASCII elevated output files; this file cannot contain the full paths and file names. Users should make sure
that the logical file names that appear in FILELIST_STACK are defined prior to running Mrgpt.
|
ADJ_FACS(optional) |
ASCII |
File that lists the species name, the logical file name, and the factor to be applied to all grid cells. The species name
must be in columns A, the logical file name in column B, and the factor in columns C. SMOKE will ignore the case of the text,
treating lower- and uppercase characters as if they were the same. For example, the following NO, PTNONIPMTS_L_INLN, 1.3 PAR, PTIPMTS_L_INLN, 0.6 |
-
MRG_DIFF_DAYS: [default: N]This environment variable allows Mrgpt to merge files with data from different days.
-
Y: Allow data from different dates to be merged together
Mrgpt will use the environment variables
G_STDATE,G_STTIME,G_RUNLEN, andG_TSTEPto set the start date, start time, length, and time step of the output file. All input files must have the same starting time asG_STTIME, the same time step asG_TSTEP, and must contain more thanG_RUNLENsteps of data. For each input file, if it contains data to cover the actual episode requested byG_STDATE,G_STTIME, andG_RUNLEN, then the data for the actual episode will be used; otherwise, data starting at the first time step of the file will be used. -
N: Require all merged data to be from the same date
Mrgpt will determine the output file time period based on the latest starting input file and the earliest ending input file.

| File Name | Format | Description |
|---|---|---|
LOGFILE |
ASCII | Log generated from executing Mrgpt |
OUTFILE_INLN |
I/O API NetCDF | Merged inline-mode hourly speciated emission file |
OUTFILE_STACK |
ASCII | Merged inline-mode ASCII point elevated file |
REPMRGGRID |
ASCII | Report file generated when MRG_DIFF_DAYS is set to Y; the report lists the date and time for each output time step along with the actual date and time of the data
read from each file
|
REPMERG_ADJ |
ASCII | Report file generated when ADJ_FACS is set; the report lists the date, the logical file name, the species name, the factor applied, a daily total of species
before and after applying adjustment factor, and the ratio (after/ratio). The report only lists when the ratio is not equal
to 1.0
