|
|
| 7 |
|
o pkg/diagnostics (velocity potential): |
| 8 |
|
- fix mask for OBCS (still problems in stream-function with OBCS); |
| 9 |
|
- add specific parameter (default = main code CG2D params) for solver; |
| 10 |
|
- in case of poor convergence, use solution corresponding to lowest residual. |
| 11 |
|
o pkg/seaice/seaice_growth.F: small changes that permit vectorizable |
| 12 |
|
adjoint code. In general statements like tmpscal=fld(i,j) are problematic |
| 13 |
|
and should be avoided where possible. |
| 14 |
|
o model/src (rStar): |
| 15 |
|
- include r* effect on reference-state (PhiRef) in totPhiHyd |
| 16 |
|
(so that it's really the potential anomaly at the cell center); |
| 17 |
|
affect solution only if z* with full pressure in EOS. |
| 18 |
|
- test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and |
| 19 |
|
update output (because of z* in totPhiHyd and viscA4 changes); |
| 20 |
|
- keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly |
| 21 |
|
@ constant r) until interpolation at constant r is implemented. |
| 22 |
|
o pkg/diagnostics |
| 23 |
|
- fix RCENTER diagnostics in case cell center is not at interface middle |
| 24 |
|
o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use |
| 25 |
|
this eos with eosType = 'TEOS10', in data (PARM01). This eos implies |
| 26 |
|
that THETA and SALT are "conservative temperature" and "absolute |
| 27 |
|
salinity" |
| 28 |
|
o pkg/ctrl |
| 29 |
|
- fix computation of endrec in s/r ctrl_init_rec |
| 30 |
|
- ctrl_pack/unpack_*: remove unused variables and some obsolete code |
| 31 |
|
o pkg/seaice/seaice_growth.F |
| 32 |
|
- fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code, |
| 33 |
|
remove then obsolete STORE directives |
| 34 |
|
- fix STORE directives for tice and tices, so that only the |
| 35 |
|
appropriate part of the fields are stored (and not the entire |
| 36 |
|
field); update global_ocean.cs32x15.seaice AD output. |
| 37 |
|
- cosmetic changes: adjust CPP flags and indentation for better |
| 38 |
|
legibilty |
| 39 |
|
o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by |
| 40 |
|
Chris Wilson) |
| 41 |
|
o pkg/gmredi: |
| 42 |
|
Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF), |
| 43 |
|
and test it in verification exp. "front_relax.bvp" (update output.bvp.txt) |
| 44 |
|
|
| 45 |
|
checkpoint63 (2011/07/11) |
| 46 |
|
o pkg/exch2: |
| 47 |
|
- rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h |
| 48 |
|
- exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the |
| 49 |
|
(2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y |
| 50 |
|
increments, calculates Cumul-Sum @ tile origin and sends results to each tile. |
| 51 |
|
o pkg/diagnostics: |
| 52 |
|
- deal with pairs of post-processed diags which are computed together; in |
| 53 |
|
particular, re-order list of diags within 1 file to save 2nd computation. |
| 54 |
|
- add S/R to compute velocity stream-function (called after velocity-potential |
| 55 |
|
calculation) from divergence free transport -> new diagnostics "PsiVEL". |
| 56 |
|
- add parameter to select grid-point location where PsiVEL == 0. |
| 57 |
|
o eesupp/src: |
| 58 |
|
new S/R to calculate cumulated sum on tiled array, corner grid-cell location |
| 59 |
|
(specific S/R needed with exch2 topology - for now, just print an error msg) |
| 60 |
|
o pkg/shelfice |
| 61 |
|
- Implement friction velocity-dependent transfer coefficients following |
| 62 |
|
Holland and Jenkins, JPO, 1999 |
| 63 |
|
Original code by M. Losch with small modifs. |
| 64 |
|
Enable with CPP option SHI_ALLOW_GAMMAFRICT |
| 65 |
|
and runtime flag SHELFICEuseGammaFrict |
| 66 |
|
o verification lab_sea & global_ocean.cs32x15: |
| 67 |
|
- use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local): |
| 68 |
|
does not miss some dependencies (but is slower) and also works with many files |
| 69 |
|
(default makedepend limitation for AD built). |
| 70 |
|
- use cyrus_makedepend in adjustment.128x64x1 (so that it still tested). |
| 71 |
|
o pkg/diagnostics: |
| 72 |
|
- add run-time parameter "useMissingValue" (def=False) to fill land-point |
| 73 |
|
(i.e., where mask=0) with MissingValue ; used only in MNC output file. |
| 74 |
|
This replaces CPP-option DIAGNOSTICS_MISSING_VALUE. |
| 75 |
|
- Extend the use of "missing_value" setting from data.diagnostics for the case |
| 76 |
|
of counter-diagnostics (where fraction-weight is zero). This applies both to |
| 77 |
|
MNC and MDS output files. |
| 78 |
|
o pkg/seaice/seaice_growth.F: |
| 79 |
|
- add 'a priori' cap of latent heat flux based on actual mass considerations |
| 80 |
|
when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the |
| 81 |
|
non-legacy seaice_solve4temp. |
| 82 |
|
- add diagnostic of the residual sublimation freshwater flux (the freshwater |
| 83 |
|
flux taken from the ocean if the total actual latent heat fluxes exceed |
| 84 |
|
the maximum) |
| 85 |
|
- remove the CPP switch around the *_FWbySublim unit change and move diagnostic |
| 86 |
|
fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F. |
| 87 |
|
- add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef |
| 88 |
|
SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim). |
| 89 |
|
- bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET. |
| 90 |
|
- bug fix : missing part to Martin's r_FWbySublim pathological case fix. |
| 91 |
|
o verification 1D_ocean_ice_column: |
| 92 |
|
made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet |
| 93 |
|
update results |
| 94 |
|
o pkg/diagnostics: |
| 95 |
|
- Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P') |
| 96 |
|
which are not filled-up but computed from other diags ; In this case, the mate |
| 97 |
|
diag points to the primary (filled-up) diag to used for post processing. |
| 98 |
|
- Update Velocity-potential computation using post-processed diag framework. |
| 99 |
|
==> Change the ordering of fields and time-periods in MDS output file |
| 100 |
|
when using periodic averaging: now writes one time record with the full set |
| 101 |
|
of fields for this time period, then the next time reccord (it used to be |
| 102 |
|
one field with the full set of time records then the next field). |
| 103 |
|
Note: this is now similar to NetCDF (MNC) output file. <== |
| 104 |
|
|
| 105 |
|
checkpoint62z (2011/06/21) |
| 106 |
|
o adjoint monitor: |
| 107 |
|
- Add adjoint monitor output for packages exf, seaice |
| 108 |
|
and update relevant testreport output |
| 109 |
|
o pkg/seaice: |
| 110 |
|
- re-order diags inits so that they appear in order in available_diagnostics.log |
| 111 |
|
- added diags: hsnow thermo. rates of change, area preceeding ridiging process, |
| 112 |
|
area/heff/hsnow preceeding thermodynamic growth/melt. |
| 113 |
|
- modified diag: SIdA; output actual effect, as the description states. |
| 114 |
|
- modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW. |
| 115 |
|
- retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh. |
| 116 |
|
(SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO; |
| 117 |
|
and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO) |
| 118 |
|
- modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates. |
| 119 |
|
- added diagnostics for seaice generic tracers (SItr*). |
| 120 |
|
- added SItrUnit and SItrNameLong run time param (for SItr* diags). |
| 121 |
|
- in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'. |
| 122 |
|
I. Fenty: 18-Jun-2011: |
| 123 |
|
Minor changes to seaice package: |
| 124 |
|
1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and |
| 125 |
|
added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor) |
| 126 |
|
- Differentiated "regularization variables" from "floor variables" |
| 127 |
|
* areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor |
| 128 |
|
* hiceMin became SEAICE_hice_reg (old hiceMin) |
| 129 |
|
(with _reg meaning regularization variable) |
| 130 |
|
- SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion |
| 131 |
|
so as to ensure energy conservation when going between phases |
| 132 |
|
- A22 was not used anywhere |
| 133 |
|
2) Changed regularization procedure for heffActual and hsnowActual to ensure |
| 134 |
|
well-boundedness and smooth adjoint in seaice_growth.F |
| 135 |
|
3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells |
| 136 |
|
because the old regularization always set heffActual >= 0.05 cm |
| 137 |
|
4) Changed the model so that the default behavior is to put a small (10^-5) "floor" |
| 138 |
|
on AREA when HEFF > 0. |
| 139 |
|
- went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to |
| 140 |
|
requiring that DISABLE_AREA_FLOOR *not* be defined |
| 141 |
|
Affected verifications: |
| 142 |
|
- 1D_ocean_ice_column (output.txt output_adm.txt) |
| 143 |
|
- global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt) |
| 144 |
|
o pkg/diagnostics: |
| 145 |
|
- move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R). |
| 146 |
|
- rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument |
| 147 |
|
(was _RL, now integer) with option = 0 to retrieve all levels. |
| 148 |
|
- add pieces of code to compute velocity potential at each level (new diagnostics |
| 149 |
|
PhiVEL, works only when UVELMASS & VVELMASS are also turned on); |
| 150 |
|
for now, using same params as CG2D (target-resisual, max Nb of iter ...). |
| 151 |
|
- fix few issues with counter diagnostics in diagnostics_setdiag.F & |
| 152 |
|
diagstats_setdiag.F (if diagnostic counter is itself a counter diag) |
| 153 |
|
and in diagnostics_fract_fill.F (do not need a valid pointer for the |
| 154 |
|
diagnostics counter-mate); check that definition of counter-diagnostic |
| 155 |
|
includes a valid counter-mate (in diagnostics_set_levels.F). |
| 156 |
|
o model/src (rStar): |
| 157 |
|
- add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F); |
| 158 |
|
affect solution only if z* with full pressure in EOS; |
| 159 |
|
update output of test-exp global_ocean.90x40x15. |
| 160 |
|
o pkg/seaice: |
| 161 |
|
- introduce siEps=1e-5 parameter |
| 162 |
|
- use areaMax in AREA update (part 4), consistent with ridging step (part 2.5). |
| 163 |
|
- re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code. |
| 164 |
|
- introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer. |
| 165 |
|
For now it covers, and was tested for, ice salinity and age (attached to HEFF), |
| 166 |
|
as well as ice cover age and ridging index (attached to AREA). |
| 167 |
|
For now the run time parameters (in data.seaice/SEAICE_PARM03) are |
| 168 |
|
SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA'). |
| 169 |
|
Up to SItrMaxNum=3 tracers can be used simultaneously. |
| 170 |
|
o pkg/salt_plume: |
| 171 |
|
-introduce SPsalFRAC run time parameter that sets the fraction of the |
| 172 |
|
salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically) |
| 173 |
|
that gets vertically redistributed (fluxed down) by pkg/salt_plume. |
| 174 |
o model debug options: |
o model debug options: |
| 175 |
- Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored |
- Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored |
| 176 |
in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h). |
in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h). |
