|
o pkg/seaice: remove (almost) all divisions by constants within loops |
| 8 |
|
in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d |
| 9 |
|
results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only |
| 10 |
|
those, caused by 1/QI -> recip_QI) -> update output.seaice.txt |
| 11 |
|
o pkg/seaice : |
| 12 |
|
- simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula.EQ. |
| 13 |
|
1 or 2, using newly added run time parameter SEAICE_availHeatTaper. |
| 14 |
|
- fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148. |
| 15 |
|
- add permanent SItflux diag that corresponds to TFLUX but includes |
| 16 |
|
ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget. |
| 17 |
|
- allow activation/testing of a fix for suspected missing term in |
| 18 |
|
ocn-ice heat budget (to be confirmed). To test this, you want to |
| 19 |
|
undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param |
| 20 |
|
SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic. |
| 21 |
|
- no change in results, fwd or ad. |
| 22 |
|
o global_ocean.cs32x15/results: three changes following from the pkg/seaice commit below. |
| 23 |
|
- switch to variable freezing point. |
| 24 |
|
Results change : cg2d -> 1 digits; ad -> 3-6-6 digits. |
| 25 |
|
- bug fix : the sublimation term that was missing is now activated. |
| 26 |
|
Results change : cg2d -> 2 digits; ad -> 8-6-6 digits. |
| 27 |
|
- bug fix : flooding sign term for SIsal0.NE.0. |
| 28 |
|
Result change : cg2d -> 8 digits; ad -> 11-12-9 digits. |
| 29 |
|
o pkg/seaice: |
| 30 |
|
- unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT |
| 31 |
|
is now the default, and the old default constant freezing point is recovered with |
| 32 |
|
SEAICE_tempFrz0 = -1.96, |
| 33 |
|
SEAICE_dTempFrz_dS = 0., |
| 34 |
|
- retire SEAICE_freeze that was the old way of specifycing the constant freezing point. |
| 35 |
|
- remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there. |
| 36 |
|
- bug fix (thanks to M. Losch) : the sublimation term that was missing is now |
| 37 |
|
activated. To reproduce old results that had this bug define SEAICE_DISABLE_SUBLIM. |
| 38 |
|
- bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211) |
| 39 |
|
was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail). |
| 40 |
|
- bug fix (thanks to O. Jahn) : area loss for melting got messed up in |
| 41 |
|
seaice_growth r149 for legacy branch (no results change). |
| 42 |
|
- introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code from I. Fenty). |
| 43 |
|
- results did not change except for global_ocean.cs32x15, mostly due to the switch |
| 44 |
|
to variable freezing point (see above item for detail). |
| 45 |
|
o pkg/thsice: |
| 46 |
|
- fix and simplify interface to salt_plume pkg ; diagnose directly amount of |
| 47 |
|
seawater freezing in thsice_calc_thickn (not used). |
| 48 |
|
o pkg/seaice: turbulent flux term specification via run time params. |
| 49 |
|
- replace CPP switches with run time switches to facilitate testing |
| 50 |
|
- retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX, GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR |
| 51 |
|
- added runtime parameter : SEAICEturbFluxFormula |
| 52 |
|
- move Mcphee constants to SEAICE_PARAMS.h |
| 53 |
|
- seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula; |
| 54 |
|
SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply); remove |
| 55 |
|
seaice_summary call (moved to seaice_init_fixed) |
| 56 |
|
- seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on |
| 57 |
|
SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms) |
| 58 |
|
- seaice_summary.F : add missing report of read turbulent flux term set up (and SITRACER). |
| 59 |
|
- seaice_check.F : check range; inform and stop if retired CPPs are used (incl. SEAICE_AGE). |
| 60 |
|
- seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without |
| 61 |
|
CPP switch, same computation as before for the different options. |
| 62 |
|
- change results at the truncation level. |
| 63 |
|
o pkg/seaice: |
| 64 |
|
- remove un-used parameters LAD & MAX_TICE ; add new run-time parameters: |
| 65 |
|
useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and |
| 66 |
|
SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY. |
| 67 |
|
- update verification/*/input*/data.seaice: |
| 68 |
|
to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY |
| 69 |
|
code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ; |
| 70 |
|
and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code, |
| 71 |
|
set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0. |
| 72 |
|
o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY): |
| 73 |
|
- remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same |
| 74 |
|
algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0); |
| 75 |
|
difference in results only due to machine truncation. |
| 76 |
|
- remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using |
| 77 |
|
MaykutPolySatVap; keep MIN_LWDOWN. |
| 78 |
|
- adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation. |
| 79 |
|
- update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87, |
| 80 |
|
+ 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits). |
| 81 |
|
o pkg/salt_plume: |
| 82 |
|
- isolate saltPlumeFlux array exch into a specific S/R called from |
| 83 |
|
do_oceanic_phys.F |
| 84 |
|
- add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice. |
| 85 |
|
o verification: |
| 86 |
|
- move untested set-up to MITgcm_contrib/verification_other. |
| 87 |
|
o pkg/seaice: |
| 88 |
|
- retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER. |
| 89 |
o pkg/seaice: |
o pkg/seaice: |
| 90 |
- seaice_solve4temp.F (keeping results unchanged): |
- seaice_solve4temp.F (keeping results unchanged): |
| 91 |
* add 2 future run-time params to select which saturation vapor pressure |
* add 2 future run-time params to select which saturation vapor pressure |
