Namelists
To run a simulation, a namelist .nml file is required, specifying the value of configuration options in a variety of categories or namelists. A diagnostic table file is also required to specify what diagnostics to save for the experiment.
Each page in this section is devoted to a particular namelist, indicating the source code where it is specified and any relevant pages on Isca's website. There are then two sections, Options and Diagnostics:
Options
This section is related to the namelist .nml file and indicates the available options that can be configured in that particular namelist, as well as their default values.
These options can be found, by looking at the module source code (e.g.
idealized_moist_phys.F90 for
idealized_moist_phys_nml) and searching for the word namelist.
You should then find some code like that below, indicating all the options in the namelist.
namelist / idealized_moist_phys_nml / turb, lwet_convection, do_bm, do_ras, &
roughness_heat, do_cloud_simple, &
two_stream_gray, do_rrtm_radiation, &
do_damping
Diagnostics
This section is related to the diagnostic table file and indicates the diagnostics relevant to the namelist that can be saved to the data directory.
These diagnostics can be found, by looking at the module source code (e.g.
idealized_moist_phys.F90 for
idealized_moist_phys_nml) and searching for the word mod_name.
You should then find some code like that below, indicating the available diagnostics for the namelist.
id_cond_dt_qg = register_diag_field(mod_name, 'dt_qg_condensation', &
axes(1:3), Time, 'Moisture tendency from condensation','kg/kg/s')
id_cond_dt_tg = register_diag_field(mod_name, 'dt_tg_condensation', &
axes(1:3), Time, 'Temperature tendency from condensation','K/s')
mod_name
The mod_name used in the diagnostic table file is not always the same
as the corresponding namelist associated with it. The table below gives the mod_name associated with each
namelist. There is a flowchart on Isca's website
which is quite useful for understanding how the modules are related to each other.
