|
o pkg/seaice: |
| 8 |
|
- seaice_solve4temp.F (keeping results unchanged): |
| 9 |
|
* add 2 future run-time params to select which saturation vapor pressure |
| 10 |
|
formula is used and how post-iteration fluxes are set. |
| 11 |
|
Temporary set these 2 params according to option SOLVE4TEMP_LEGACY; |
| 12 |
|
* New piece of code (not used) to update surf. atmos. heat flux F_ia using |
| 13 |
|
the linearized expression to stay consistent with tsurf finding. |
| 14 |
|
- seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x |
| 15 |
|
can be < 0. |
| 16 |
|
o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef): |
| 17 |
|
- remove from F_ia (and from it's derivative dFiDTs1) the contribution of |
| 18 |
|
conductive heat flux F_c , and add it explicitly when updating tsurf as |
| 19 |
|
solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf |
| 20 |
|
so that now F_ia has a consistent meaning through the entire routine. |
| 21 |
|
This causes differences at truncation level: update output of fwd exp. |
| 22 |
|
global_ocean.cs32x15.seaice. |
| 23 |
|
o pkg/seaice: |
| 24 |
|
- lots of editing/cleaning in seaice_solve4temp.F + better documentation |
| 25 |
|
of arrays, sign/direction of fluxes; no effect on results. |
| 26 |
|
- replace hard coded 273.16 (=previous value of celsius2K) by celsius2K |
| 27 |
|
in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part); |
| 28 |
|
note: this should have been done before changing celsius2K default. |
| 29 |
|
- to keep results unchanged, add back old value of celsius2K in verification |
| 30 |
|
exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs |
| 31 |
|
- replace hard coded seawater freezing temp in seaice_solve4temp.F (part |
| 32 |
|
SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default |
| 33 |
|
value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater |
| 34 |
|
freezing temp is consistent with value in seaice_growth.F ; this causes |
| 35 |
|
differences at machine truncation level: update lab_sea AD output (3/4). |
| 36 |
|
o pkg/seaice: |
| 37 |
|
- mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask |
| 38 |
|
and climsst/sss even when using seaice (to prevent calculation that might |
| 39 |
|
use SST on land); does not affect any verification exp. |
| 40 |
|
- apply mask to taux,tauy (in seaice_get_dynforcing.F); update output |
| 41 |
|
of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix. |
| 42 |
|
o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness |
| 43 |
|
over land (non-legacy code) |
| 44 |
|
o vectorize salt_plume package: |
| 45 |
|
- add extra code to salt_plume_frac and salt_plume_tendency_apply_s |
| 46 |
|
- this code computes plumebk everywhere (also over land), thus requires |
| 47 |
|
code to avoid divisions by zero and catch the case of kLev=Nr. |
| 48 |
|
- efficiency of salt_plume_frac is still sub-optimal |
| 49 |
|
o tools (genmake2): |
| 50 |
|
- fix makefile NAME specification (option: -makefile NAME) by adding |
| 51 |
|
"-f $MAKEFILE" in few places where it was missing including makedepend |
| 52 |
|
command (contribution from Paul). |
| 53 |
|
|
| 54 |
|
checkpoint63i (2012/01/24) |
| 55 |
|
o model/src: |
| 56 |
|
- add factorized versions of some EOS code to find_rho.F, |
| 57 |
|
define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX) |
| 58 |
|
o model/src: |
| 59 |
|
- add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h; |
| 60 |
|
- change default celsius2K from 273.16 to 273.15 |
| 61 |
|
- to keep results unchanged, add back old value of celsius2K in verification |
| 62 |
|
exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd), |
| 63 |
|
global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm). |
| 64 |
|
o model/src: add a little initialisation trick to find_rho.F and find_alpha.F |
| 65 |
|
to make TAF generate vectorizable code |
| 66 |
|
o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows. |
| 67 |
|
Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers |
| 68 |
|
have flags that do this more efficiently. |
| 69 |
|
o pkg/diagnostics/diagstats_calc.F |
| 70 |
|
- for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact |
| 71 |
|
o pkg/obcs (with exch2): |
| 72 |
|
- derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F) |
| 73 |
|
and remove code (in obcs_readparms.F) which was based on EXCH of indices |
| 74 |
|
(through buffer) and did not account for exch2 (e.g., CS-grid) topology. |
| 75 |
|
o pkg/exf and seaice exp: |
| 76 |
|
- change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0) |
| 77 |
|
so that switching off area & heff advection flags does not affect results. |
| 78 |
|
- change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h |
| 79 |
|
- keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef |
| 80 |
|
EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update |
| 81 |
|
results of verification experiments: 1D_ocean_ice_column(fwd), |
| 82 |
|
global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8) |
| 83 |
|
and offline_exf_seaice (all 4). |
| 84 |
|
o pkg/seaice: |
| 85 |
|
- remove array YNEG, RIVER, TMIX (replaced by local var) from common block; |
| 86 |
|
remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef. |
| 87 |
|
- fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY) |
| 88 |
|
but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and |
| 89 |
|
not multi-dim advection; |
| 90 |
|
- fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and |
| 91 |
|
SHORTWAVE_HEATING #undef. |
| 92 |
|
o optim: make Makefile more robust (?) |
| 93 |
|
o pkg/obcs: |
| 94 |
|
* fix treatment of obcs_read_pickup for TAF |
| 95 |
|
o pkg/shelfice: |
| 96 |
|
* add missing initialisation of num_shifwflx |
| 97 |
|
* new adjoint verification exp. for isomip |
| 98 |
|
* change Prandtl and Schmidt numbers from generic formulations |
| 99 |
|
(in terms of model diffus. and visc.) to separate runtime |
| 100 |
|
parameters, with Holland and Jenkins (1999) default values. |
| 101 |
|
o pkg/exf (interpolation): |
| 102 |
|
- extended input field (2 rows) near the N & S poles: |
| 103 |
|
* fill in with the symetric value (when even Nb of data in longitude) |
| 104 |
|
* add average value at the poles only for scalar quantities ; for vector |
| 105 |
|
component interpolation, skip the averaging and keep duplicated values, |
| 106 |
|
unless the 2 components have same location (uvInterp=T) in which case |
| 107 |
|
interpolate the 2 components together using S/R EXF_INTERP_UV. |
| 108 |
|
- new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field |
| 109 |
|
together: this allows to account properly for local orientation when |
| 110 |
|
averaging at N & S pole. |
| 111 |
|
- add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding |
| 112 |
|
exf-interpolation near N & S poles. Undef by default. |
| 113 |
|
- add debug check/print on 1rst iter if debugLevel >=2. |
| 114 |
|
o pkg/exf: |
| 115 |
|
- change masking flags definition (no longer "parameter"), put them in |
| 116 |
|
common block and set them in S/R EXF_INIT_FIXED. |
| 117 |
|
- change recognized masking flag from s,u,v to c,w,s since the mask |
| 118 |
|
to use (maskC,W,S) depends on position on model grid and has little to |
| 119 |
|
do with scalar/vector difference; fix masking if using P-coordinates. |
| 120 |
|
- fix masking of wind-stress (was wrong if interpolated or read on A-grid) |
| 121 |
|
and update results of exp. global_with_exf (x2). |
| 122 |
|
- fix setting of zenith-angle table when SHORTWAVE_HEATING is undef. |
| 123 |
|
o pkg/obcs |
| 124 |
|
- S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate) |
| 125 |
|
o pkg/exf (interpolation): |
| 126 |
|
- assume periodicity in X only if input field cover full longitude range. |
| 127 |
|
- improve search for lat. index (supposed to be faster, in ~log2(ny) steps, |
| 128 |
|
and should vectorise). |
| 129 |
|
- fix input lat of the 2 added row (in case we provide N.pole data). |
| 130 |
|
|
| 131 |
|
checkpoint63h (2011/12/30) |
| 132 |
|
o pkg/seaice: |
| 133 |
|
- change declaration of UVM from _RL to _RS in order to get B-grid |
| 134 |
|
uIce,vIce monitor when _RS = real*4 |
| 135 |
|
o pkg/offline: |
| 136 |
|
- new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags); |
| 137 |
|
- compute vertical velocity if not read from file (switch on exactConserv |
| 138 |
|
& staggerTimeStep); |
| 139 |
|
- fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq. |
| 140 |
|
o verification: |
| 141 |
|
- update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input) |
| 142 |
|
with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m": |
| 143 |
|
fix Pb in yG definition @ 2 missing corners (previously yG was averaged); |
| 144 |
|
- update output of exp. global_ocean.cs32x15.viscA4 after changing |
| 145 |
|
grid-file angles (used here for coriolis-3d); |
| 146 |
|
- remove (or gzip) few files not needed to run fizhi-cs experiments. |
| 147 |
|
o pkg/exf (vector interpolation): |
| 148 |
|
- rotate vector component toward local grid-axis orientation using grid-angles |
| 149 |
|
(stored in GRID.h) instead of locally computed rotation angle; keep old code |
| 150 |
|
available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default). |
| 151 |
|
o pkg/seaice: |
| 152 |
|
- allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION |
| 153 |
|
undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined. |
| 154 |
|
o pkg/PKG_OPTIONS.h files: |
| 155 |
|
- move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h", |
| 156 |
|
outside of the #ifdef ALLOW_THISPKG / #endif block. |
| 157 |
|
- update verification/*/code/PKG_OPTIONS.h files. |
| 158 |
|
o add a verification experiment (offline_exf_seaice/input.seaice) that test |
| 159 |
|
the B-grid LSOR solver |
| 160 |
o pkg/seaice: sort out emissivity and long wave radiation step 2: |
