| 9 |
|
- Add adjoint monitor output for packages exf, seaice |
| 10 |
|
and update relevant testreport output |
| 11 |
|
o pkg/seaice: |
| 12 |
|
- re-order diags inits so that they appear in order in available_diagnostics.log |
| 13 |
|
- added diags: hsnow thermo. rates of change, area preceeding ridiging process, |
| 14 |
|
area/heff/hsnow preceeding thermodynamic growth/melt. |
| 15 |
|
- modified diag: SIdA; output actual effect, as the description states. |

| 17 |
|
- retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh. |
| 18 |

I. Fenty: 18-Jun-2011: |
| 25 |
|
Minor changes to seaice package: |
| 26 |
|
1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and |
| 27 |
|
added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor) |
| 28 |
|
- Differentiated "regularization variables" from "floor variables" |
| 29 |
|
* areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor |
| 30 |
|
* hiceMin became SEAICE_hice_reg (old hiceMin) |
| 31 |
|
(with _reg meaning regularization variable) |
| 32 |
|
- SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion |
| 33 |
|
so as to ensure energy conservation when going between phases |
| 34 |
|
- A22 was not used anywhere |
| 35 |
|
2) Changed regularization procedure for heffActual and hsnowActual to ensure |
| 36 |
|
well-boundedness and smooth adjoint in seaice_growth.F |
| 37 |
|
3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells |
| 38 |
|
because the old regularization always set heffActual >= 0.05 cm |
| 39 |
|
4) Changed the model so that the default behavior is to put a small (10^-5) "floor" |
| 40 |
|
on AREA when HEFF > 0. |
| 41 |
|
- went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to |
| 42 |
|
requiring that DISABLE_AREA_FLOOR *not* be defined |
| 43 |
|
Affected verifications: |
| 44 |
|
- 1D_ocean_ice_column (output.txt output_adm.txt) |
| 45 |
|
- global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt) |
| 46 |
|
o pkg/diagnostics: |
| 47 |
|
- move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R). |
| 48 |
|
- rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument |
| 49 |
|
(was _RL, now integer) with option = 0 to retrieve all levels. |
| 50 |
|
- add pieces of code to compute velocity potential at each level (new diagnostics |
| 51 |
|
PhiVEL, works only when UVELMASS & VVELMASS are also turned on); |
| 52 |
|
for now, using same params as CG2D (target-resisual, max Nb of iter ...). |
| 53 |
|
- fix few issues with counter diagnostics in diagnostics_setdiag.F & |
| 54 |
|
diagstats_setdiag.F (if diagnostic counter is itself a counter diag) |
| 55 |
|
and in diagnostics_fract_fill.F (do not need a valid pointer for the |
| 56 |
|
diagnostics counter-mate); check that definition of counter-diagnostic |
| 57 |
|
includes a valid counter-mate (in diagnostics_set_levels.F). |
| 58 |
|
o model/src (rStar): |
| 59 |
|
- add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F); |
| 60 |
|
affect solution only if z* with full pressure in EOS; |
| 61 |
|
update output of test-exp global_ocean.90x40x15. |
| 62 |
|
o pkg/seaice: |
| 63 |
|
- introduce siEps=1e-5 parameter |
| 64 |
|
- use areaMax in AREA update (part 4), consistent with ridging step (part 2.5). |
| 65 |
|
- re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code. |
| 66 |
|
- introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer. |
| 67 |
|
For now it covers, and was tested for, ice salinity and age (attached to HEFF), |
| 68 |
|
as well as ice cover age and ridging index (attached to AREA). |
| 69 |
|
For now the run time parameters (in data.seaice/SEAICE_PARM03) are |
| 70 |
|
SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA'). |
| 71 |
|
Up to SItrMaxNum=3 tracers can be used simultaneously. |
| 72 |
|
o pkg/salt_plume: |
| 73 |
|
-introduce SPsalFRAC run time parameter that sets the fraction of the |
| 74 |
|
salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically) |
| 75 |
|
that gets vertically redistributed (fluxed down) by pkg/salt_plume. |
| 76 |
|
o model debug options: |
| 77 |
|
- Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored |
| 78 |
|
in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h). |
| 79 |
|
- Refine debug-msg printing selection (3 new levels): |
| 80 |
|
debugMode : controls printing of debug messages (sequence of S/R calls). |
| 81 |
|
debugLevel : controls printing of algorithm-relevant auxiliary/debug messages |
| 82 |
|
debLevZero = 0 ; /* level of disabled aux. msg printing */ |
| 83 |
|
debLevA = 1 ; /* level of minimum aux. msg printing */ |
| 84 |
|
debLevB = 2 ; /* level of low aux. print (report read-file opening)*/ |
| 85 |
|
debLevC = 3 ; /* level of moderate debug prt (most pkgs debug msg) */ |
| 86 |
|
debLevD = 4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */ |
| 87 |
|
debLevE = 5 ; /* level of extensive debug printing */ |
| 88 |
|
New debugLevel default: with default debugMode value (=F), |
| 89 |
|
= 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.; |
| 90 |
|
and if debugMode=T, default debugLevel = 4 (debLevD). |
| 91 |
|
Relation with previous settings: |
| 92 |
|
debLevB (=2) corresponds to former debLevA (=1) |
| 93 |
|
debLevD (=4) corresponds to former debLevB (=2) |
| 94 |
|
Note: |
| 95 |
|
a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before); |
| 96 |
|
b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs); |
| 97 |
|
to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5) |
| 98 |
|
- Add new parameter (printResidualFreq, read from PARM02 namelist) to print |
| 99 |
|
detailed CG solvers convergence; off (=0) by default, except if debugLevel=5. |
| 100 |
|
o pkg/obcs: |
| 101 |
|
- change OBCSfixTopo default from True to False (should not change the results); |
| 102 |
|
keep OBCSfixTopo=T in verification-exp. seaice_obcs. |
| 103 |
o pkg/thsice: |
o pkg/thsice: |
| 104 |
- fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in |
- fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in |
| 105 |
