How to reset the FCST_VAR and 1FCST_UNITS in Config file

[Ho-ChunHuang-NOAA]

The FCST_VAR and FCST_UNITS in the output PointStats are read from the FCST grib2 file, e.g., MASSDEN and kg/m^3.

(a) I have two PointStat both with fcst var name as "MASSDEN" from fcst_input_grib2_file but for different meaning. I want to rename the output fcst_var_name in the output PointStat file so I can identified proper variable in the following plots step, e.g. VAR_CHG. I tried

POINT_STAT_FCST_VAR = NA

but nothing changed.

(b) The PointStat input fcst unit is in "kg/m^3". When computing PointStat, it was converted to 10^-6g/m^3 then compared with the observation which the unit is 10^-6g/m^3. The output PointStat column "FCST_UNITS" remains to be "kg/m^3". I would like to rename the FCST_UNITS in the PointStat output as "10^-6g/m^3" for the following plot step.

I tried

POINT_STAT_FCST_UNITS = NA

But nothing changed in PointStat output.

Have anyone try to overwrite the default METPlus setting ? Please let me know if you found a way to do it.

I am aware that I can use "sed -e" to replace "MASSDEN" to "VAR_CHG" of a ascii file at the command line. I simply want to know whether it can be done using different METPlus config setting.

I have an example of renaming the variable and units here

Thank you Mallory. Your example is helpful to reset the FCST_VAR and FCST_UNITS in the output stats files.
