Update on testing mrgpt program:

Confirming several corrections need to be made either to src/smkmerge/mrgpt.f or to section 4.11.3 in SMOKE Userguide (UG):

• mrgpt looks for FILELIST_S instead of FILELIST_STACK as stated in UG
• mrgpt looks for FILELIST_E instead of FILELIST_INLN as stated in UG
• mrgpt uses OUTFILE_S instead of OUTFILE_STACK as output file for merged stack group
• mrgpt uses OUTFILE_E instead of OUTFILE_INLN as output for merged inline stack emission
• REPMRGGRID and REPMERG_ADJ have no effect as there are no report files created in accordance with these settings
• Setting for CREATE_REPORT variable (Y or N) needs to be added to UG. This tells mrgpt to write report file or not. Name of the report file is determined by setting of REPORT_BY_STATE
• Setting for REPORT_BY_STATE (format ASCII file) need to be added to UG to specify output report filename

Additional findings from this test:

• Typo in the header of REPORT_BY_STATE report file where "SATET FIP" should be corrected to "STATE FIPS"
• Currently MRG_DIFF_DAYS (Y|N) has no effect. mrgpt will crash if there is no overlap time in the input files even with MRG_DIFF_DAYS set to Y

In overall it looks like mrgpt is a rough addoption of mrggrid with quite a few incompletions which need improvements.

Update on testing inline2d:

Confirming that section 3.3.6 of SMOKE User Guide needs update to include descriptions of required environmental variables GRIDDESC and IOAPI_GRIDNAME_1 (src/emutil/inlineto2d.f calls external function src/lib/dscm3grd.f which checks for these two variable).
