user_nl_mpaso--output variables

[Xinyuan-Lv]

Hi,

In the case: GMPAS-NYF (grid: T62_oQU480), I want to change output variables by user_nl_mpaso. There are some questions:

1 I am looking for output variable names for the MPAS-O component of E3SM-1.2.0. What's the short name for each variable? And, what are the default output variables? Where are they recorded?
2 As a first step, I just want to try to get an mpaso output file that contains only the potential temperature.

Here is my user_nl_mpaso looks like:
hist_empty_htapes = .true.
hist_fincl1 = 'TEMP'

After './case.setup --reset':
ERROR: Command: '/home/lxyccyethz/e3sm-1.2.0/components/mpas-ocean/bld/build-namelist -infile /home/lxyccyethz/e3sm-1.2.0/cime/scripts/GMPAS-NYF_T62_oQU480/Buildconf/mpasoconf/cesm_namelist -caseroot /home/lxyccyethz/e3sm-1.2.0/cime/scripts/GMPAS-NYF_T62_oQU480 -casebuild /home/lxyccyethz/e3sm-1.2.0/cime/scripts/GMPAS-NYF_T62_oQU480/Buildconf -cimeroot /home/lxyccyethz/e3sm-1.2.0/cime -inst_string '' -decomp_prefix 'mpas-o.graph.info.' -date_stamp '151209' -ocn_grid 'oQU480' -ocn_forcing 'datm_forced' -ocn_iceberg 'false' -ocn_ismf 'false' -ocn_bgc 'no_bgc' -ocn_co2_type 'constant' -atm_co2_const_val '379.0' -ice_bgc 'no_ice_bgc' -ntasks_ocn '64' -ninst_ocn '1'' failed with error 'b'** ERROR: either hist_empty_htapes is not a valid MPASO namelist variable or hist_empty_htapes = .true. is not a valid value; please fix user_nl_mpaso. Note that hist_empty_htapes may appear in multiple namelists, in which case you need to specify the correct namelist in user_nl_mpaso using the format hist_empty_htapes&namelist_nml = .true., where &namelist_nml is the mpaso_in namelist containing hist_empty_htapes.**'' from dir '/home/lxyccyethz/e3sm-1.2.0/cime/scripts/GMPAS-NYF_T62_oQU480/Buildconf/mpasoconf'

Therefore, in mpaso, does user_nl_mpaso have its own rules? What changes should I make to achieve my small goal?

In addition, according to the default setting of this case, there are several mpaso related files to be output. When modifying the output variable, does the system specify to generate a new file? Is the default output of these files unchanged?

Thanks in advance!
