Description
Context
The application of namelist integrity checking tools to 4.0-HEAD@13089 revealed several irregularities that this ticket seeks to address. Most are resolved with trivial changes but a couple of the changes proposed here should be reviewed by those more familiar with those parts of the code. Namely the changes to the PISCES reference namelist and to the stochastic parameterisation module.
Analysis
Firstly, there are two changes to the code base to replace valid code with code more conformant with the conventions used elsewhere. These are merely to allow the namelist integrity checks to correctly identify namelists.
The first is uncontroversial and merely inserts a leading ampersand on a continuation line:
-
OCE/SBC/sbcwave.F90
391 391 & sn_tauwoc, sn_tauwx, sn_tauwy ! informations about the fields to be read 392 392 ! 393 393 NAMELIST/namsbc_wave/ sn_cdg, cn_dir, sn_usd, sn_vsd, sn_hsw, sn_wmp, sn_wfr, & 394 394 & sn_wnum, sn_tauwoc, sn_tauwx, sn_tauwy 395 395 !!--------------------------------------------------------------------- 396 396 ! 397 397 REWIND( numnam_ref ) ! Namelist namsbc_wave in reference namelist : File for drag coeff. from wave model
The second should also be uncontroversial unless there was an obscure reason for appending to the namelist in the manner used uniquely in bdydta.F90 (alignment of variables? Problems with a particular compiler?). Otherwise, the proposal is to replace the multiple declarations with a single declaration and continuation lines:
-
OCE/BDY/bdydta.F90
395 395 TYPE(FLD_N), DIMENSION(:), POINTER :: bn_alias ! must be an array to be used with fld_fill 396 396 TYPE(FLD ), DIMENSION(:), POINTER :: bf_alias 397 397 ! 398 NAMELIST/nambdy_dta/ cn_dir, bn_tem, bn_sal, bn_u3d, bn_v3d, bn_ssh, bn_u2d, bn_v2d 399 NAMELIST/nambdy_dta/ bn_a_i, bn_h_i, bn_h_s, bn_t_i, bn_t_s, bn_tsu, bn_s_i, bn_aip, bn_hip400 NAMELIST/nambdy_dta/ rn_ice_tem, rn_ice_sal, rn_ice_age, rn_ice_apnd, rn_ice_hpnd401 NAMELIST/nambdy_dta/ln_full_vel, ln_zinterp398 NAMELIST/nambdy_dta/ cn_dir, bn_tem, bn_sal, bn_u3d, bn_v3d, bn_ssh, bn_u2d, bn_v2d, & 399 & bn_a_i, bn_h_i, bn_h_s, bn_t_i, bn_t_s, bn_tsu, bn_s_i, bn_aip, bn_hip, & 400 & rn_ice_tem, rn_ice_sal, rn_ice_age, rn_ice_apnd, rn_ice_hpnd, & 401 & ln_full_vel, ln_zinterp 402 402 !!--------------------------------------------------------------------------- 403 403 ! 404 404 IF(lwp) WRITE(numout,*)
With these changes the namelist integrity checks reveal the issues shown in part 3 of:
Namelist checks
Many of the issues flagged relating to derived type variables (sn*) or array varaibles are not real issues. They are flagged simply because only the derived type name or array name appears in the namelist declaration but individual elements are set in the namelists. Ignoring these items there are still the following issues to be addressed:
Recommendation
OCE
ln_rnf_icb declared in namsbc_rnf (sbcrnf.F90) with no namelist_ref entry sn_i_rnf declared in namsbc_rnf (sbcrnf.F90) with no namelist_ref entry ln_time_average_weight declared in namberg (icb_oce.F90, icbini.F90) with no namelist_ref entry a large block of 23 variables declared in namsto (stopar.F90) with no namelist_ref entries
The first two of these are related and seem to be a simple omission. The proposed change is to add them to the namelist_ref:
-
SHARED/namelist_ref
416 416 rn_rnf_max = 5.735e-4 ! max value of the runoff climatologie over global domain ( ln_rnf_depth_ini = .true ) 417 417 rn_dep_max = 150. ! depth over which runoffs is spread ( ln_rnf_depth_ini = .true ) 418 418 nn_rnf_depth_file = 0 ! create (=1) a runoff depth file or not (=0) 419 ln_rnf_icb = .false. ! read in iceberg flux from a file (fill sn_i_rnf if .true.) 419 420 420 421 cn_dir = './' ! root directory for the runoff data location 421 422 !___________!_________________________!___________________!___________!_____________!________!___________!__________________!__________!_______________! … … 426 427 sn_s_rnf = 'runoffs' , 24. , 'rosaline', .true. , .true. , 'yearly' , '' , '' , '' 427 428 sn_t_rnf = 'runoffs' , 24. , 'rotemper', .true. , .true. , 'yearly' , '' , '' , '' 428 429 sn_dep_rnf = 'runoffs' , 0. , 'rodepth' , .false. , .true. , 'yearly' , '' , '' , '' 430 sn_i_rnf = 'NOT_USED' , -1. , 'sorunoff', .true. , .true. , 'yearly' , '' , '' , '' 429 431 / 430 432 !----------------------------------------------------------------------- 431 433 &namsbc_apr ! Atmospheric pressure used as ocean forcing (ln_apr_dyn =T)
The next variable is a logical switch which has no code to activate and no explanation of its intention. The proposed change is to remove it:

The unused stochastic parameterisation variables present more of a dilemma. The entire namsto namelist declared in stopar.F90 is:
NAMELIST/namsto/ ln_sto_ldf, rn_ldf_std, rn_ldf_tcor, & & ln_sto_hpg, rn_hpg_std, rn_hpg_tcor, & & ln_sto_pstar, rn_pstar_std, rn_pstar_tcor, nn_pstar_flt, nn_pstar_ord, & & ln_sto_trd, rn_trd_std, rn_trd_tcor, & & ln_sto_eos, nn_sto_eos, rn_eos_stdxy, rn_eos_stdz, & & rn_eos_tcor, nn_eos_ord, nn_eos_flt, rn_eos_lim, & & ln_sto_trc, nn_sto_trc, rn_trc_stdxy, rn_trc_stdz, & & rn_trc_tcor, nn_trc_ord, nn_trc_flt, rn_trc_lim, & & ln_rststo, ln_rstseed, cn_storst_in, cn_storst_out
but of these only:
NAMELIST/namsto/ ln_sto_eos, nn_sto_eos, rn_eos_stdxy, rn_eos_stdz, & & rn_eos_tcor, nn_eos_ord, nn_eos_flt, rn_eos_lim, & & ln_rststo, ln_rstseed, cn_storst_in, cn_storst_out
are reported to ocean.output. The intent seems to be to limit access to only these options but the other options could be activated via the namelist and will activate code within the stochastic parameterisation module. The proposed change here is to properly disable the other options by:
-

TOP
The issues found in the TOP code reduce to just two mis-spelt variables and two missing default settings in namelist_top_ref. In fact the two missing character strings don't seem to have defaults set in the code either so the choice made here should be verified:
-
namelist_top_ref
121 121 nn_trd_trc = 5475 ! time step frequency and tracers trends 122 122 nn_ctls_trc = 0 ! control surface type in mixed-layer trends (0,1 or n<jpk) 123 123 rn_ucf_trc = 1 ! unit conversion factor (=1 -> /seconds ; =86400. -> /day) 124 ln_trdmld_trc_restart = .false. ! restart for ML diagnostics 125 ln_trdmld_trc_instant = .true. ! flag to diagnose trends of instantantaneous or mean ML T/S 124 ln_trdmxl_trc_restart = .false. ! restart for ML diagnostics 125 ln_trdmxl_trc_instant = .true. ! flag to diagnose trends of instantantaneous or mean ML T/S 126 cn_trdrst_trc_in = 'restart_trd' ! suffix of pass. tracer trends restart name (input) 127 cn_trdrst_trc_out = 'restart_trd' ! suffix of pass. tracer trends restart name (output) 126 128 ln_trdtrc( 1) = .true. 127 129 ln_trdtrc( 2) = .true. 128 130 ln_trdtrc(23) = .true.
PISCES
The issues found in PISCES are just two mis-spelt variables. Because there are many variables sharing names between the p4z and p5z versions it isn't immediately obvious what the correct choices are. The changes proposed here are a best guess but both the choice of variable and the validity of the default value should be verified:
