============================== |
============================== |
| 6 |
|
|
| 7 |
|
o pkg/seaice: |
| 8 |
|
- remove un-used parameters LAD & MAX_TICE ; add new run-time parameters: |
| 9 |
|
useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and |
| 10 |
|
SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY. |
| 11 |
|
- update verification/*/input*/data.seaice: |
| 12 |
|
to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY |
| 13 |
|
code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ; |
| 14 |
|
and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code, |
| 15 |
|
set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0. |
| 16 |
|
o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY): |
| 17 |
|
- remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same |
| 18 |
|
algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0); |
| 19 |
|
difference in results only due to machine truncation. |
| 20 |
|
- remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using |
| 21 |
|
MaykutPolySatVap; keep MIN_LWDOWN. |
| 22 |
|
- adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation. |
| 23 |
|
- update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87, |
| 24 |
|
+ 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits). |
| 25 |
|
o pkg/salt_plume: |
| 26 |
|
- isolate saltPlumeFlux array exch into a specific S/R called from |
| 27 |
|
do_oceanic_phys.F |
| 28 |
|
- add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice. |
| 29 |
|
o verification: |
| 30 |
|
- move untested set-up to MITgcm_contrib/verification_other. |
| 31 |
|
o pkg/seaice: |
| 32 |
|
- retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER. |
| 33 |
|
o pkg/seaice: |
| 34 |
|
- seaice_solve4temp.F (keeping results unchanged): |
| 35 |
|
* add 2 future run-time params to select which saturation vapor pressure |
| 36 |
|
formula is used and how post-iteration fluxes are set. |
| 37 |
|
Temporary set these 2 params according to option SOLVE4TEMP_LEGACY; |
| 38 |
|
* New piece of code (not used) to update surf. atmos. heat flux F_ia using |
| 39 |
|
the linearized expression to stay consistent with tsurf finding. |
| 40 |
|
- seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x |
| 41 |
|
can be < 0. |
| 42 |
|
o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef): |
| 43 |
|
- remove from F_ia (and from it's derivative dFiDTs1) the contribution of |
| 44 |
|
conductive heat flux F_c , and add it explicitly when updating tsurf as |
| 45 |
|
solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf |
| 46 |
|
so that now F_ia has a consistent meaning through the entire routine. |
| 47 |
|
This causes differences at truncation level: update output of fwd exp. |
| 48 |
|
global_ocean.cs32x15.seaice. |
| 49 |
|
o pkg/seaice: |
| 50 |
|
- lots of editing/cleaning in seaice_solve4temp.F + better documentation |
| 51 |
|
of arrays, sign/direction of fluxes; no effect on results. |
| 52 |
|
- replace hard coded 273.16 (=previous value of celsius2K) by celsius2K |
| 53 |
|
in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part); |
| 54 |
|
note: this should have been done before changing celsius2K default. |
| 55 |
|
- to keep results unchanged, add back old value of celsius2K in verification |
| 56 |
|
exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs |
| 57 |
|
- replace hard coded seawater freezing temp in seaice_solve4temp.F (part |
| 58 |
|
SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default |
| 59 |
|
value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater |
| 60 |
|
freezing temp is consistent with value in seaice_growth.F ; this causes |
| 61 |
|
differences at machine truncation level: update lab_sea AD output (3/4). |
| 62 |
|
o pkg/seaice: |
| 63 |
|
- mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask |
| 64 |
|
and climsst/sss even when using seaice (to prevent calculation that might |
| 65 |
|
use SST on land); does not affect any verification exp. |
| 66 |
|
- apply mask to taux,tauy (in seaice_get_dynforcing.F); update output |
| 67 |
|
of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix. |
| 68 |
|
o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness |
| 69 |
|
over land (non-legacy code) |
| 70 |
|
o vectorize salt_plume package: |
| 71 |
|
- add extra code to salt_plume_frac and salt_plume_tendency_apply_s |
| 72 |
|
- this code computes plumebk everywhere (also over land), thus requires |
| 73 |
|
code to avoid divisions by zero and catch the case of kLev=Nr. |
| 74 |
|
- efficiency of salt_plume_frac is still sub-optimal |
| 75 |
|
o tools (genmake2): |
| 76 |
|
- fix makefile NAME specification (option: -makefile NAME) by adding |
| 77 |
|
"-f $MAKEFILE" in few places where it was missing including makedepend |
| 78 |
|
command (contribution from Paul). |
| 79 |
|
|
| 80 |
|
checkpoint63i (2012/01/24) |
| 81 |
|
o model/src: |
| 82 |
|
- add factorized versions of some EOS code to find_rho.F, |
| 83 |
|
define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX) |
| 84 |
|
o model/src: |
| 85 |
|
- add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h; |
| 86 |
|
- change default celsius2K from 273.16 to 273.15 |
| 87 |
|
- to keep results unchanged, add back old value of celsius2K in verification |
| 88 |
|
exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd), |
| 89 |
|
global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm). |
| 90 |
|
o model/src: add a little initialisation trick to find_rho.F and find_alpha.F |
| 91 |
|
to make TAF generate vectorizable code |
| 92 |
|
o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows. |
| 93 |
|
Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers |
| 94 |
|
have flags that do this more efficiently. |
| 95 |
|
o pkg/diagnostics/diagstats_calc.F |
| 96 |
|
- for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact |
| 97 |
|
o pkg/obcs (with exch2): |
| 98 |
|
- derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F) |
| 99 |
|
and remove code (in obcs_readparms.F) which was based on EXCH of indices |
| 100 |
|
(through buffer) and did not account for exch2 (e.g., CS-grid) topology. |
| 101 |
|
o pkg/exf and seaice exp: |
| 102 |
|
- change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0) |
| 103 |
|
so that switching off area & heff advection flags does not affect results. |
| 104 |
|
- change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h |
| 105 |
|
- keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef |
| 106 |
|
EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update |
| 107 |
|
results of verification experiments: 1D_ocean_ice_column(fwd), |
| 108 |
|
global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8) |
| 109 |
|
and offline_exf_seaice (all 4). |
| 110 |
|
o pkg/seaice: |
| 111 |
|
- remove array YNEG, RIVER, TMIX (replaced by local var) from common block; |
| 112 |
|
remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef. |
| 113 |
|
- fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY) |
| 114 |
|
but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and |
| 115 |
|
not multi-dim advection; |
| 116 |
|
- fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and |
| 117 |
|
SHORTWAVE_HEATING #undef. |
| 118 |
|
o optim: make Makefile more robust (?) |
| 119 |
|
o pkg/obcs: |
| 120 |
|
* fix treatment of obcs_read_pickup for TAF |
| 121 |
|
o pkg/shelfice: |
| 122 |
|
* add missing initialisation of num_shifwflx |
| 123 |
|
* new adjoint verification exp. for isomip |
| 124 |
|
* change Prandtl and Schmidt numbers from generic formulations |
| 125 |
|
(in terms of model diffus. and visc.) to separate runtime |
| 126 |
|
parameters, with Holland and Jenkins (1999) default values. |
| 127 |
|
o pkg/exf (interpolation): |
| 128 |
|
- extended input field (2 rows) near the N & S poles: |
| 129 |
|
* fill in with the symetric value (when even Nb of data in longitude) |
| 130 |
|
* add average value at the poles only for scalar quantities ; for vector |
| 131 |
|
component interpolation, skip the averaging and keep duplicated values, |
| 132 |
|
unless the 2 components have same location (uvInterp=T) in which case |
| 133 |
|
interpolate the 2 components together using S/R EXF_INTERP_UV. |
| 134 |
|
- new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field |
| 135 |
|
together: this allows to account properly for local orientation when |
| 136 |
|
averaging at N & S pole. |
| 137 |
|
- add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding |
| 138 |
|
exf-interpolation near N & S poles. Undef by default. |
| 139 |
|
- add debug check/print on 1rst iter if debugLevel >=2. |
| 140 |
|
o pkg/exf: |
| 141 |
|
- change masking flags definition (no longer "parameter"), put them in |
| 142 |
|
common block and set them in S/R EXF_INIT_FIXED. |
| 143 |
|
- change recognized masking flag from s,u,v to c,w,s since the mask |
| 144 |
|
to use (maskC,W,S) depends on position on model grid and has little to |
| 145 |
|
do with scalar/vector difference; fix masking if using P-coordinates. |
| 146 |
|
- fix masking of wind-stress (was wrong if interpolated or read on A-grid) |
| 147 |
|
and update results of exp. global_with_exf (x2). |
| 148 |
|
- fix setting of zenith-angle table when SHORTWAVE_HEATING is undef. |
| 149 |
|
o pkg/obcs |
| 150 |
|
- S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate) |
| 151 |
|
o pkg/exf (interpolation): |
| 152 |
|
- assume periodicity in X only if input field cover full longitude range. |
| 153 |
|
- improve search for lat. index (supposed to be faster, in ~log2(ny) steps, |
| 154 |
|
and should vectorise). |
| 155 |
|
- fix input lat of the 2 added row (in case we provide N.pole data). |
| 156 |
|
|
| 157 |
|
checkpoint63h (2011/12/30) |
| 158 |
|
o pkg/seaice: |
| 159 |
|
- change declaration of UVM from _RL to _RS in order to get B-grid |
| 160 |
|
uIce,vIce monitor when _RS = real*4 |
| 161 |
|
o pkg/offline: |
| 162 |
|
- new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags); |
| 163 |
|
- compute vertical velocity if not read from file (switch on exactConserv |
| 164 |
|
& staggerTimeStep); |
| 165 |
|
- fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq. |
| 166 |
|
o verification: |
| 167 |
|
- update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input) |
| 168 |
|
with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m": |
| 169 |
|
fix Pb in yG definition @ 2 missing corners (previously yG was averaged); |
| 170 |
|
- update output of exp. global_ocean.cs32x15.viscA4 after changing |
| 171 |
|
grid-file angles (used here for coriolis-3d); |
| 172 |
|
- remove (or gzip) few files not needed to run fizhi-cs experiments. |
| 173 |
|
o pkg/exf (vector interpolation): |
| 174 |
|
- rotate vector component toward local grid-axis orientation using grid-angles |
| 175 |
|
(stored in GRID.h) instead of locally computed rotation angle; keep old code |
| 176 |
|
available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default). |
| 177 |
|
o pkg/seaice: |
| 178 |
|
- allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION |
| 179 |
|
undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined. |
| 180 |
|
o pkg/PKG_OPTIONS.h files: |
| 181 |
|
- move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h", |
| 182 |
|
outside of the #ifdef ALLOW_THISPKG / #endif block. |
| 183 |
|
- update verification/*/code/PKG_OPTIONS.h files. |
| 184 |
|
o add a verification experiment (offline_exf_seaice/input.seaice) that test |
| 185 |
|
the B-grid LSOR solver |
| 186 |
|
o pkg/seaice: sort out emissivity and long wave radiation step 2: |
| 187 |
|
- add emissivity for snow and ice as new run-time parameters |
| 188 |
|
(unfortunately) that default to the corresponding exf values; this |
| 189 |
|
changes results in most verification experiments so that for backward |
| 190 |
|
compatibility these parameter have to be set explicitly to inconsistent |
| 191 |
|
values (ugly); |
| 192 |
|
- the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired |
| 193 |
|
emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp |
| 194 |
|
until we agree how to handle this bug properly |
| 195 |
|
o pkg/exf (interpolation): |
| 196 |
|
- add a set of run-time param ({inputfield}_interpMethod), one for |
| 197 |
|
each interpolated input field, to select the interpolation method |
| 198 |
|
with a value of zero switching off the interpolation; |
| 199 |
|
- print interpolation parameters to standard output; |
| 200 |
|
- refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined |
| 201 |
|
(to use instead runoff_interpMethod=0 in data.exf). |
| 202 |
|
- simplify default setting of interpolation parameters (for all fields, |
| 203 |
|
set position to match model grid cell-center position, leading to trivial |
| 204 |
|
interpolation in case of regular Lat-Lon grid) and fix for the case of |
| 205 |
|
non-uniform delY. |
| 206 |
|
o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for |
| 207 |
|
within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1. |
| 208 |
|
this factor is absolutely required, because the lw exitance (= out-going |
| 209 |
|
long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown, |
| 210 |
|
where the reflectivity rho = 1-emissivity for conservation reasons. Once |
| 211 |
|
this is established, we can remove the CPP-Flag (if we want to). |
| 212 |
|
o pkg/seaice: |
| 213 |
|
- qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and |
| 214 |
|
ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined |
| 215 |
|
- sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity |
| 216 |
|
what the name implies (and not emissivity*BoltzmannConstant), this means |
| 217 |
|
the old default value of 5.5e-8 now means |
| 218 |
|
5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in |
| 219 |
|
S/R exf_readparms |
| 220 |
|
- FV-discretization of the B-grid LSOR solver, turn on with |
| 221 |
|
SEAICE_LSRBNEW. This new solver also involves a slight re-organization |
| 222 |
|
of the calling routine dynsolver, so that B and C-grid code look a |
| 223 |
|
little more alike. |
| 224 |
|
- fix index bugs in ostres.F (B-grid code) |
| 225 |
|
o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better |
| 226 |
|
o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the |
| 227 |
|
default for SEAICE_emissivity, if useEXF; requires setting a wrong |
| 228 |
|
parameter value in global_ocean.cs32x15/input.seaice/data.seaice for |
| 229 |
|
backward compatiblity |
| 230 |
|
o model/src: use sigmaR in calc_ivdc |
| 231 |
|
|
| 232 |
|
checkpoint63g (2011/12/16) |
| 233 |
|
o pkg/seaice/seaice_growth.F: |
| 234 |
|
fix heat conservation of the coupled ocean-seaice system. |
| 235 |
|
when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of |
| 236 |
|
solid vs liquid water treatment is resolved via QNET. |
| 237 |
|
o pkg/seaice/seaice_growth.F: |
| 238 |
|
add missing term for sublimation in saltFlux, which was breaking conservation. |
| 239 |
|
o pkg/seaice/seaice_model.F: |
| 240 |
|
Remove this patholigical case treatment in evolution branch, |
| 241 |
|
where it is un-necessary and breaks conservation. |
| 242 |
|
Update global_ocean.cs32x15/results accordingly for |
| 243 |
|
output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt |
| 244 |
|
o model/src: |
| 245 |
|
useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in |
| 246 |
|
external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE. |
| 247 |
|
o pkg/obcs: |
| 248 |
|
modify Stevens boundary conditions so that S/R obcs_calc_stevens computes |
| 249 |
|
tendency for temperature and salinity that is then applied to update |
| 250 |
|
theta and salt in S/R obcs_apply_ts; this requires proper masking of all |
| 251 |
|
horizontal advection and diffusion contributions on the boundary (in |
| 252 |
|
S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and |
| 253 |
|
removing the mask in S/R timestep_tracer. The advantage of this approach is |
| 254 |
|
that the updated tracer values include contributions from the surface |
| 255 |
|
forcing and vertical diffusion. |
| 256 |
|
This modification changes exp4.stevens because of vertical diffusion. |
| 257 |
|
o model/src: |
| 258 |
|
change non-curvilinear grid setting to also work with exch2 + blank tiles: |
| 259 |
|
- move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst |
| 260 |
|
face dimensions. |
| 261 |
|
- new S/R INI_LOCAL_GRID to define model tile-local grid (using same units |
| 262 |
|
as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID |
| 263 |
|
and INI_SPHERICAL_POLAR_GRID. |
| 264 |
|
change test-experiment global_ocean.90x40x15: |
| 265 |
|
- split the domain in many more tiles (9x4 tiles of 10x10 each); |
| 266 |
|
- switch to exch2 and remove 1 blank-tile (but only for MPI test). |
| 267 |
|
- update results of both test (std & dwnslp). |
| 268 |
|
o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in |
| 269 |
|
tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation |
| 270 |
|
o model/src: |
| 271 |
|
- take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS |
| 272 |
|
and fix initialisation when using sigma-coords. |
| 273 |
o model/src: |
o model/src: |
| 274 |
- improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc. |
- improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc. |
| 275 |
to their current value at the beginning of forward_step.F": add a new run-time |
to their current value at the beginning of forward_step.F": add a new run-time |
| 276 |
switch "doResetHFactors" (default=false) and use it to do (or not) the resetting. |
switch "doResetHFactors" (default=false) and use it to do (or not) the resetting. |
| 277 |
