5      ==============================      ==============================
6    
7  o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for  o pkg/seaice: turbulent flux term specification via run time params.
8      - replace CPP switches with run time switches to facilitate testing
9      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX, GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
10      - added runtime parameter : SEAICEturbFluxFormula
11      - move Mcphee constants to SEAICE_PARAMS.h
12      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
13       SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply); remove
14       seaice_summary call (moved to seaice_init_fixed)
15      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
16       SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
17      - seaice_summary.F : add missing report of read turbulent flux term set up (and SITRACER).
18      - seaice_check.F : check range; inform and stop if retired CPPs are used (incl. SEAICE_AGE).
19      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
20            CPP switch, same computation as before for the different options.
21      - change results at the truncation level.
22    o pkg/seaice:
23      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
24        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
25        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
26      - update verification/*/input*/data.seaice:
27        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
28        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
29        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
30        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
31    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
32      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
33        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
34        difference in results only due to machine truncation.
35      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
36        MaykutPolySatVap; keep MIN_LWDOWN.
37      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
38      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
39        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
40    o pkg/salt_plume:
41      - isolate saltPlumeFlux array exch into a specific S/R called from
42        do_oceanic_phys.F
43      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
44    o verification:
45      - move untested set-up to MITgcm_contrib/verification_other.
46    o pkg/seaice:
47      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
48    o pkg/seaice:
49      - seaice_solve4temp.F (keeping results unchanged):
50        * add 2 future run-time params to select which saturation vapor pressure
51          formula is used and how post-iteration fluxes are set.
52          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
53        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
54          the linearized expression to stay consistent with tsurf finding.
55      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
56        can be < 0.
57    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
58      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
59        conductive heat flux F_c , and add it explicitly when updating tsurf as
60        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
61        so that now F_ia has a consistent meaning through the entire routine.
62        This causes differences at truncation level: update output of fwd exp.
63        global_ocean.cs32x15.seaice.
64    o pkg/seaice:
65      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
66        of arrays, sign/direction of fluxes; no effect on results.
67      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
68        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
69        note: this should have been done before changing celsius2K default.
70      - to keep results unchanged, add back old value of celsius2K in verification
71        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
72      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
73        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
74        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
75        freezing temp is consistent with value in seaice_growth.F ; this causes
76        differences at machine truncation level: update lab_sea AD output (3/4).
77    o pkg/seaice:
78      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
79        and climsst/sss even when using seaice (to prevent calculation that might
80        use SST on land); does not affect any verification exp.
81      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
82        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
83    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
84      over land (non-legacy code)
85    o vectorize salt_plume package:
86      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
87      - this code computes plumebk everywhere (also over land), thus requires
88        code to avoid divisions by zero and catch the case of kLev=Nr.
89      - efficiency of salt_plume_frac is still sub-optimal
90    o tools (genmake2):
91      - fix makefile NAME specification (option: -makefile NAME) by adding
92        "-f $MAKEFILE" in few places where it was missing including makedepend
93        command (contribution from Paul).
94    
95    checkpoint63i (2012/01/24)
96    o model/src:
97      - add factorized versions of some EOS code to find_rho.F,
98        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
99    o model/src:
100      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
101      - change default celsius2K from 273.16 to 273.15
102      - to keep results unchanged, add back old value of celsius2K in verification
103        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
104         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
105    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
106      to make TAF generate vectorizable code
107    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
108       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
109       have flags that do this more efficiently.
110    o pkg/diagnostics/diagstats_calc.F
111      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
112    o pkg/obcs (with exch2):
113      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
114        and remove code (in obcs_readparms.F) which was based on EXCH of indices
115        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
116    o pkg/exf and seaice exp:
117      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
118        so that switching off area & heff advection flags does not affect results.
119      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
120      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
121        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
122        results of verification experiments: 1D_ocean_ice_column(fwd),
123        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
124        and offline_exf_seaice (all 4).
125    o pkg/seaice:
126      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
127        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
128      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
129        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
130        not multi-dim advection;
131      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
132        SHORTWAVE_HEATING #undef.
133    o optim: make Makefile more robust (?)
134    o pkg/obcs:
135      * fix treatment of obcs_read_pickup for TAF
136    o pkg/shelfice:
137      * add missing initialisation of num_shifwflx
138      * new adjoint verification exp. for isomip
139      * change Prandtl and Schmidt numbers from generic formulations
140        (in terms of model diffus. and visc.) to separate runtime
141        parameters, with Holland and Jenkins (1999) default values.
142    o pkg/exf (interpolation):
143      - extended input field (2 rows) near the N & S poles:
144        * fill in with the symetric value (when even Nb of data in longitude)
145        * add average value at the poles only for scalar quantities ; for vector
146          component interpolation, skip the averaging and keep duplicated values,
147          unless the 2 components have same location (uvInterp=T) in which case
148          interpolate the 2 components together using S/R EXF_INTERP_UV.
149      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
150        together: this allows to account properly for local orientation when
151        averaging at N & S pole.
152      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
153        exf-interpolation near N & S poles. Undef by default.
154      - add debug check/print on 1rst iter if debugLevel >=2.
155    o pkg/exf:
156      - change masking flags definition (no longer "parameter"), put them in
157        common block and set them in S/R EXF_INIT_FIXED.
158      - change recognized masking flag from s,u,v to c,w,s since the mask
159        to use (maskC,W,S) depends on position on model grid and has little to
160        do with scalar/vector difference; fix masking if using P-coordinates.
161      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
162        and update results of exp. global_with_exf (x2).
163      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
164    o pkg/obcs
165      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
166    o pkg/exf (interpolation):
167      - assume periodicity in X only if input field cover full longitude range.
168      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
169        and should vectorise).
170      - fix input lat of the 2 added row (in case we provide N.pole data).
171    
172    checkpoint63h (2011/12/30)
173    o pkg/seaice:
174      - change declaration of UVM from _RL to _RS in order to get B-grid
175        uIce,vIce monitor when _RS = real*4
176    o pkg/offline:
177      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
178      - compute vertical velocity if not read from file (switch on exactConserv
179        & staggerTimeStep);
180      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
181    o verification:
182      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
183        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
184        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
185      - update output of exp. global_ocean.cs32x15.viscA4 after changing
186        grid-file angles (used here for coriolis-3d);
187      - remove (or gzip) few files not needed to run fizhi-cs experiments.
188    o pkg/exf (vector interpolation):
189      - rotate vector component toward local grid-axis orientation using grid-angles
190        (stored in GRID.h) instead of locally computed rotation angle; keep old code
191        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
192    o pkg/seaice:
193      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
194        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
195    o pkg/PKG_OPTIONS.h files:
196      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
197        outside of the #ifdef ALLOW_THISPKG / #endif block.
198      - update verification/*/code/PKG_OPTIONS.h files.
199    o add a verification experiment (offline_exf_seaice/input.seaice) that test
200      the B-grid LSOR solver
201    o pkg/seaice: sort out emissivity and long wave radiation step 2:
202      - add emissivity for snow and ice as new run-time parameters
203        (unfortunately) that default to the corresponding exf values; this
204        changes results in most verification experiments so that for backward
205        compatibility these parameter have to be set explicitly to inconsistent
206        values (ugly);
207      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
208        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
209        until we agree how to handle this bug properly
210    o pkg/exf (interpolation):
211      - add a set of run-time param ({inputfield}_interpMethod), one for
212        each interpolated input field, to select the interpolation method
213        with a value of zero switching off the interpolation;
214      - print interpolation parameters to standard output;
215      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
216        (to use instead runoff_interpMethod=0 in data.exf).
217      - simplify default setting of interpolation parameters (for all fields,
218        set position to match model grid cell-center position, leading to trivial
219        interpolation in case of regular Lat-Lon grid) and fix for the case of
220        non-uniform delY.
221    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
222     within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.     within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
223     this factor is absolutely required, because the lw exitance (= out-going     this factor is absolutely required, because the lw exitance (= out-going

225     where the reflectivity rho = 1-emissivity for conservation reasons. Once     where the reflectivity rho = 1-emissivity for conservation reasons. Once
226     this is established, we can remove the CPP-Flag (if we want to).     this is established, we can remove the CPP-Flag (if we want to).
