5      ==============================      ==============================
6    
7    o global_ocean.cs32x15/results: three changes following from the pkg/seaice commit below.
8      - switch to variable freezing point.
9           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
10      - bug fix : the sublimation term that was missing is now activated.
11           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
12      - bug fix : flooding sign term for SIsal0.NE.0.
13           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
14    o pkg/seaice:
15      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
16     is now the default, and the old default constant freezing point is recovered with
17     SEAICE_tempFrz0    = -1.96,
18     SEAICE_dTempFrz_dS = 0.,
19      - retire SEAICE_freeze that was the old way of specifycing the constant freezing point.
20      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
21      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
22     activated. To reproduce old results that had this bug define SEAICE_DISABLE_SUBLIM.
23      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
24     was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
25      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
26     seaice_growth r149 for legacy branch (no results change).
27      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code from I. Fenty).
28      - results did not change except for global_ocean.cs32x15, mostly due to the switch
29      to variable freezing point (see above item for detail).
30    o pkg/thsice:
31      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
32        seawater freezing in thsice_calc_thickn (not used).
33    o pkg/seaice: turbulent flux term specification via run time params.
34      - replace CPP switches with run time switches to facilitate testing
35      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX, GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
36      - added runtime parameter : SEAICEturbFluxFormula
37      - move Mcphee constants to SEAICE_PARAMS.h
38      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
39        SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply); remove
40        seaice_summary call (moved to seaice_init_fixed)
41      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
42        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
43      - seaice_summary.F : add missing report of read turbulent flux term set up (and SITRACER).
44      - seaice_check.F : check range; inform and stop if retired CPPs are used (incl. SEAICE_AGE).
45      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
46            CPP switch, same computation as before for the different options.
47      - change results at the truncation level.
48    o pkg/seaice:
49      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
50        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
51        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
52      - update verification/*/input*/data.seaice:
53        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
54        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
55        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
56        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
57    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
58      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
59        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
60        difference in results only due to machine truncation.
61      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
62        MaykutPolySatVap; keep MIN_LWDOWN.
63      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
64      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
65        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
66    o pkg/salt_plume:
67      - isolate saltPlumeFlux array exch into a specific S/R called from
68        do_oceanic_phys.F
69      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
70    o verification:
71      - move untested set-up to MITgcm_contrib/verification_other.
72    o pkg/seaice:
73      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
74    o pkg/seaice:
75      - seaice_solve4temp.F (keeping results unchanged):
76        * add 2 future run-time params to select which saturation vapor pressure
77          formula is used and how post-iteration fluxes are set.
78          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
79        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
80          the linearized expression to stay consistent with tsurf finding.
81      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
82        can be < 0.
83    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
84      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
85        conductive heat flux F_c , and add it explicitly when updating tsurf as
86        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
87        so that now F_ia has a consistent meaning through the entire routine.
88        This causes differences at truncation level: update output of fwd exp.
89        global_ocean.cs32x15.seaice.
90    o pkg/seaice:
91      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
92        of arrays, sign/direction of fluxes; no effect on results.
93      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
94        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
95        note: this should have been done before changing celsius2K default.
96      - to keep results unchanged, add back old value of celsius2K in verification
97        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
98      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
99        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
100        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
101        freezing temp is consistent with value in seaice_growth.F ; this causes
102        differences at machine truncation level: update lab_sea AD output (3/4).
103    o pkg/seaice:
104      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
105        and climsst/sss even when using seaice (to prevent calculation that might
106        use SST on land); does not affect any verification exp.
107      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
108        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
109    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
110      over land (non-legacy code)
111    o vectorize salt_plume package:
112      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
113      - this code computes plumebk everywhere (also over land), thus requires
114        code to avoid divisions by zero and catch the case of kLev=Nr.
115      - efficiency of salt_plume_frac is still sub-optimal
116    o tools (genmake2):
117      - fix makefile NAME specification (option: -makefile NAME) by adding
118        "-f $MAKEFILE" in few places where it was missing including makedepend
119        command (contribution from Paul).
120    
121    checkpoint63i (2012/01/24)
122    o model/src:
123      - add factorized versions of some EOS code to find_rho.F,
124        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
125    o model/src:
126      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
127      - change default celsius2K from 273.16 to 273.15
128      - to keep results unchanged, add back old value of celsius2K in verification
129        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
130         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
131    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
132      to make TAF generate vectorizable code
133    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
134       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
135       have flags that do this more efficiently.
136    o pkg/diagnostics/diagstats_calc.F
137      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
138    o pkg/obcs (with exch2):
139      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
140        and remove code (in obcs_readparms.F) which was based on EXCH of indices
141        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
142    o pkg/exf and seaice exp:
143      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
144        so that switching off area & heff advection flags does not affect results.
145      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
146      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
147        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
148        results of verification experiments: 1D_ocean_ice_column(fwd),
149        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
150        and offline_exf_seaice (all 4).
151    o pkg/seaice:
152      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
153        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
154      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
155        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
156        not multi-dim advection;
157      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
158        SHORTWAVE_HEATING #undef.
159    o optim: make Makefile more robust (?)
160    o pkg/obcs:
161      * fix treatment of obcs_read_pickup for TAF
162    o pkg/shelfice:
163      * add missing initialisation of num_shifwflx
164      * new adjoint verification exp. for isomip
165      * change Prandtl and Schmidt numbers from generic formulations
166        (in terms of model diffus. and visc.) to separate runtime
167        parameters, with Holland and Jenkins (1999) default values.
168    o pkg/exf (interpolation):
169      - extended input field (2 rows) near the N & S poles:
170        * fill in with the symetric value (when even Nb of data in longitude)
171        * add average value at the poles only for scalar quantities ; for vector
172          component interpolation, skip the averaging and keep duplicated values,
173          unless the 2 components have same location (uvInterp=T) in which case
174          interpolate the 2 components together using S/R EXF_INTERP_UV.
175      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
176        together: this allows to account properly for local orientation when
177        averaging at N & S pole.
178      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
179        exf-interpolation near N & S poles. Undef by default.
180      - add debug check/print on 1rst iter if debugLevel >=2.
181    o pkg/exf:
182      - change masking flags definition (no longer "parameter"), put them in
183        common block and set them in S/R EXF_INIT_FIXED.
184      - change recognized masking flag from s,u,v to c,w,s since the mask
185        to use (maskC,W,S) depends on position on model grid and has little to
186        do with scalar/vector difference; fix masking if using P-coordinates.
187      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
188        and update results of exp. global_with_exf (x2).
189      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
190    o pkg/obcs
191      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
192    o pkg/exf (interpolation):
193      - assume periodicity in X only if input field cover full longitude range.
194      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
195        and should vectorise).
196      - fix input lat of the 2 added row (in case we provide N.pole data).
197    
198    checkpoint63h (2011/12/30)
199    o pkg/seaice:
200      - change declaration of UVM from _RL to _RS in order to get B-grid
201        uIce,vIce monitor when _RS = real*4
202    o pkg/offline:
203      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
204      - compute vertical velocity if not read from file (switch on exactConserv
205        & staggerTimeStep);
206      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
207    o verification:
208      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
209        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
210        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
211      - update output of exp. global_ocean.cs32x15.viscA4 after changing
212        grid-file angles (used here for coriolis-3d);
213      - remove (or gzip) few files not needed to run fizhi-cs experiments.
214    o pkg/exf (vector interpolation):
215      - rotate vector component toward local grid-axis orientation using grid-angles
216        (stored in GRID.h) instead of locally computed rotation angle; keep old code
217        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
218    o pkg/seaice:
219      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
220        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
221    o pkg/PKG_OPTIONS.h files:
222      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
223        outside of the #ifdef ALLOW_THISPKG / #endif block.
224      - update verification/*/code/PKG_OPTIONS.h files.
225    o add a verification experiment (offline_exf_seaice/input.seaice) that test
226      the B-grid LSOR solver
227    o pkg/seaice: sort out emissivity and long wave radiation step 2:
228      - add emissivity for snow and ice as new run-time parameters
229        (unfortunately) that default to the corresponding exf values; this
230        changes results in most verification experiments so that for backward
231        compatibility these parameter have to be set explicitly to inconsistent
232        values (ugly);
233      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
234        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
235        until we agree how to handle this bug properly
236    o pkg/exf (interpolation):
237      - add a set of run-time param ({inputfield}_interpMethod), one for
238        each interpolated input field, to select the interpolation method
239        with a value of zero switching off the interpolation;
240      - print interpolation parameters to standard output;
241      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
242        (to use instead runoff_interpMethod=0 in data.exf).
243      - simplify default setting of interpolation parameters (for all fields,
244        set position to match model grid cell-center position, leading to trivial
245        interpolation in case of regular Lat-Lon grid) and fix for the case of
246        non-uniform delY.
247    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
248       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
249       this factor is absolutely required, because the lw exitance (= out-going
250       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
251       where the reflectivity rho = 1-emissivity for conservation reasons. Once
252       this is established, we can remove the CPP-Flag (if we want to).
253    o pkg/seaice:
254      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
255        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
256      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
257        what the name implies (and not emissivity*BoltzmannConstant), this means
258        the old default value of 5.5e-8 now means
259        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
260        S/R exf_readparms
261      - FV-discretization of the B-grid LSOR solver, turn on with
262        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
263        of the calling routine dynsolver, so that B and C-grid code look a
264        little more alike.
265      - fix index bugs in ostres.F (B-grid code)
266    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
267    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
268      default for SEAICE_emissivity, if useEXF; requires setting a wrong
269      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
270      backward compatiblity
271    o model/src: use sigmaR in calc_ivdc
272    
273    checkpoint63g (2011/12/16)
274    o pkg/seaice/seaice_growth.F:
275      fix heat conservation of the coupled ocean-seaice system.
276      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
277      solid vs liquid water treatment is resolved via QNET.
278    o pkg/seaice/seaice_growth.F:
279      add missing term for sublimation in saltFlux, which was breaking conservation.
280    o pkg/seaice/seaice_model.F:
281      Remove this patholigical case treatment in evolution branch,
282      where it is un-necessary and breaks conservation.
283      Update global_ocean.cs32x15/results accordingly for
284      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
285    o model/src:
286      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
287      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
288    o pkg/obcs:
289      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
290      tendency for temperature and salinity that is then applied to update
291      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
292      horizontal advection and diffusion contributions on the boundary (in
293      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
294      removing the mask in S/R timestep_tracer. The advantage of this approach is
295      that the updated tracer values include contributions from the surface
296      forcing and vertical diffusion.
297      This modification changes exp4.stevens because of vertical diffusion.
298    o model/src:
299      change non-curvilinear grid setting to also work with exch2 + blank tiles:
300      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
301        face dimensions.
302      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
303        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
304        and INI_SPHERICAL_POLAR_GRID.
305      change test-experiment global_ocean.90x40x15:
306      - split the domain in many more tiles (9x4 tiles of 10x10 each);
307      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
308      - update results of both test (std & dwnslp).
309    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
310       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
311    o model/src:
312      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
313        and fix initialisation when using sigma-coords.
314    o model/src:
315     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
316       to their current value at the beginning of forward_step.F": add a new run-time
317       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
318     - set doResetHFactors=T in the following test exp:
319        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
320        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
321        and tutorial_global_oce_in_p (nonLinFS in p)
322    o pkg/ecco
323      - added IES cost term
324    o verification/advect_xz
325      - scale down the depth by 1/100 (from 200 km to just 2.km)
326      - add secondary test using divergent flow, r-star and implicit vertical advection.
327      - add note (check_conserve_TS.txt) and matlab script to check global
328        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
329    o pkg/rbcs:
330      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
331    o pkg/obcs (Stevens BCs):
332      - fix various problems in the phase speed computations of the Stevens
333        boundary conditions:
334        - sign error for western and southern boundaries,
335        - time tendencies were underestimated by factor of dTracerLev and some just
336          zero (for multidim advection schemes) -> now estimate time tendencies
337          from difference between previous (n) time level and the one before (n-1);
338          this requires storing a field per tracer per boundary, also in the pickup
339          files.
340        - replace deltaTmom in cflMer/Zon computation with dTracerLev
341        - set default phase velocity to cflMer/Zon
342      - update verification experiment exp4.stevens
343    o pkg/generic_advdiff (implicit_r):
344      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
345        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
346      - fix implicit vertical diffusion or advection with NonLin FreeSurf
347        (was using current recip_hFacC instead of future recip_hFacC): set future
348        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
349        solver S/R ;
350      - fill diagnostics of vertical advective fluxes (computed from tendency)
351        when using implicit vert. advection;
352      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
353         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
354         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
355         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
356    o pkg/diagnostics:
357      - add diags for T & S tendency which goes through Adams-Bashforth.
358    
359    checkpoint63f (2011/11/30)
360    o pkg/obcs/obcs_calc_stevens.F:
361      - join some loops to reduce number of if-statements
362      - fix a bug in code for northern and southern boundaries.
363    o pkg/seaice/seaice_init_varia.F
364      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
365        caused zero ice-velocities for the B-grid code
366    o pkg/seaice/seaice_init_fixed.F
367      - fix a bug in the initialisation of the second metric terms
368        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
369      - this affects all seaice configurations with useCurviLinearGrid = .true.
370        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
371        = .true. (default)
372      - the only verification experiment affected is global_ocean.cs32x15:
373        icedyn, seaice, and seaice_dynmix (AD)
374    o pkg/thsice/thsice_diagnostics_state.F
375      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
376        not contain garbage that can lead to surprises in diagstats_calc.F
377    o model/src:
378      - move bi,bj loops inside INTEGR_CONTINUITY ;
379      - call INTEGR_CONTINUITY directly from forward_step.F
380        (previously called from momentum_correction_step.F)
381      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
382        forward_step.F and pkg/ecco/the_main_loop.F
383    o model/src/do_oceanic_phys.F:
384      - reset addMass to zero only if useICEFRONT ;
385      - separated k-loop for rhoInSitu calculation ;
386      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
387        and at constant T,S (= WdRHOdP);
388      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
389        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
390        transport of locally-referenced potential density);
391        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
392    o gluemnc:
393      - replace ncrcat with ncks when adding variables to *.glob.nc
394      - change the way variables without record dimensions are handled so that
395        files that have variables with and without record variables can be glued:
396        add a record dimension with a new unique name to be able to differentiate
397        between variable with and without a-prior record dimensions. Remove
398        this record dimension before adding the variable to the *.glob.nc file.
399        This procedure automatically works also for grid.*.nc files that do not
400        have any record dimension.
401    o verification/cpl_aim+ocn:
402      - generate new reference output on baudelaire (gfortran, mpich2) (previously
403        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
404    o pkg/obcs/obcs_calc_stevens.F:
405      - add code for northern and southern boundaries.
406      - reorder some loops to save some operations and so that drFBar can be scalar
407    o model/src:
408      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
409        truncation) and add diagnostics for Adams-Bashforth tendency increment.
410      - update test-exp. AD output:
411        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
412      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
413        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
414        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
415        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
416        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
417        tutorial_plume_on_slope.
418    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
419      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
420      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
421      does not even come with an F77 compiler anymore, this should not be
422      a limitation
423    
424    checkpoint63e (2011/11/06)
425    o pkg/seaice adjoint of LSR:
426      - substantially rework STORE dirs.
427      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
428        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
429        and only perform SOLV_MAX_FIXED adjoint iters.
430        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
431        always goes to same record, meaning that the last forward field will be
432        the one used in the adjoint - an approximation.
433      - now produces non-zero LSR-related gradients, and acceptable gradients for
434        An's zonal (x-z) test case (to be checked in)
435      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
436        (but these are screwed up by the thermodynamics in the first place);
437        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
438        output_adm.txt also reflects changes to seaice_lsr
439      - global_ocean.cs32x15:
440        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
441          (output_adm.seaice.txt was updated)
442        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
443          (output_adm.seaice_dynmix.txt)
444    o test-exp. exp4+stevens:
445      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
446    o pkg/seaice (lsr solver):
447      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
448        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
449      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
450      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
451        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
452      - compute (with new S/R) and print initial (+ free-driff sol. if available)
453        and final residual of linearised system.
454    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
455      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
456    o pkg/obcs: Stevens BCs (still only for east and west)
457      - fix Stevens BCs by using intermediate velocities of previous
458        time step as "baroclinic" contribution rather velocity of one grid cell
459        inside the boundaries; more consistent but makes the entire treatment
460        more complicated, requires new pickup files and two new S/Rs:
461        obcs_copy_uv_n and obcs_save_uv_n
462        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
463        (undefined by default)
464      - silently move computation of some grid factors into separate loops to
465        save some recomputations
466      - add a hack for non-linear free surface
467      - add a verification experiment to exp4 that tests this code
468    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
469    
470    checkpoint63d (2011/10/25)
471    o pkg/obcs + seaice-dynamics:
472      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
473        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
474        values (consistent with an implicit method).
475      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
476        return to older implementation (same results as before); note that none of
477        the "experimental" OBCS_SEAICE options are implemented in the new version.
478      - switch test exp. seaice_obcs to use new version (update output).
479    o pkg/seaice:
480      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
481      - add parenthesis in Water-Ice drag calculations (evp & lsr);
482      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
483        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
484      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
485        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
486    o pkg/layers:
487      - Include potential density as new coordinate (Thanks to David Munday)
488    o pkg/dic:
489      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
490        carbonate computation/output to CALC_PCO2_APPROX
491    o pkg/generic_advdiff
492      - make TAF generate code that vectorizes:
493        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
494    o model/src:
495      - improve vectorization also for adjoint code of
496        solve_tridiagonal and solve_pentadiagonal. As this requires up to
497        5 new 3D-fields, this code is only turned on for the combination of
498        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
499        for singular matrix check (only for TARGET_NEC_SX).
500      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
501        ALLOW_AUTODIFF. This flag now needs to be set outside of
502        solve_tri/pentadiagonal.F
503    o pkg/exf:
504      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
505        optional namelist EXF_NML_OBCS).
506      - add many debug-print (to trace down where pkg/cal error msg comes from)
507    o pkg/mom_vecinv/mom_vi_hdissip.F
508      - rearrange loops so that vectorization is improved and in particular
509        the adjoint routine vectorizes. The code is a little longer now, but I
510        think easier to read.
511        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
512    o pkg/seaice:
513      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
514    o pkg/exch2:
515      - alternative code (without tile x tile matrix) for cumulated (global) sum;
516        used as default; keep using matrix version in adjustment.cs-32x32x1.
517    o tools/build_options:
518      - after merging some MPI and/or multi-threads specific optfiles so that
519        the modified default optfile support both built (using genmake2 -mpi
520        for the MPI built, using genmake2 -omp for OpenMP built),
521        move now obsolete optfiles to tools/build_options/unsupported/
522       (add copy of email sent to support list in doc/optfiles_changes.txt)
523    
524    checkpoint63c (2011/09/28)
525    o pkg/ebm:
526      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
527        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
528    o pkg/seaice (SItracer pickup)
529    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
530      To be done:
531      - thorough testing of missing fields in S/R seaice_read_pickup
532      - thorough matching between generic tracers and specific fields used
533        (e.g. volume-weighted age, area-weighted age, salinity, ...)
534    o pkg/grdchk:
535      - all procs calculate and print finite-difference gradient (for testreport)
536      - change description output used by testreport;
537      - AD testing: also compare and report Finite-difference gradient;
538        => update all output_adm*.txt
539    o test exp. global_ocean_ebm:
540      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
541        and turn on exactConserve; update (fwd) output.
542    o pkg/seaice (LSR):
543      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
544      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
545        * identical results with non-CS topology (but save up to half of EXCH calls)
546        * no much changes in cs-32 verification tests since no ice at face edges
547         (differences due to convergence criteria, since nb of iterations changed)
548        * expect some differences on lat-lon-cap grid.
549        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
550    o pkg/exch2:
551      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
552        many tiles); until alternative coding is added, just add a stop.
553    o pkg/kpp:
554      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
555        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
556    o optfiles:
557      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
558        into corresponding standard one, which now support different build:
559        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
560      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
561    o pkg/obcs (seaice):
562      - add missing EXCH for uIce,vIce after applying OBCS;
563      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
564        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
565        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
566      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
567      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
568        and eedata.mth for MPI and mutlti-threaded testing.
569    o pkg/flt:
570      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
571      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
572      - fix pickup and trajectories + profiles output with multi-threads;
573      - add parameter to select group of fields to write along trajectory and
574        profile (default unchanged);
575      - only call PORT_RAND* function when flt_noise <> 0;
576      - add multi-threaded test for verification exp. flt_example.
577    o eesupp/src:
578      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
579      - USE_OMP_THREADING: check that number of threads (from eedata) matches
580        actual number (from env.var. setting).
581    o pkg/ebm:
582      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
583      - add multi-threaded test for verification exp. global_ocean_ebm
584    
585    checkpoint63b (2011/08/29)
586    o pkg/ebm:
587      - fix sign of runoff;
588      - update directly forcing fields (Qnet,EmPmR) to use standard
589        external_forcing_surf.F (remove ebm_forcing_surf.F);
590      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
591      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
592        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
593      - update global_ocean_ebm parameters file data and update output (fwd+ad).
594    o verification/matrix_example:
595      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
596        MPI and mutlti-threaded testing.
597    o pkg/matrix:
598      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
599      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
600      - fix for multi-threaded (remove DATA statement);
601      - use standard DIFFERENT_MULTIPLE function;
602      - add MATRIX_OPTIONS.h
603    o verification/matrix_example:
604       To allow to split the domain in several tiles, change the domain size
605        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
606        Western side) of land points.
607    o (*_)write_pickup:
608      - fix few bugs in mypackage_read/write_pickup.F
609      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
610        array of length 1 (was caught by compiler syntax-check).
611    o pkg/diagnostics (velocity potential solver):
612      - fix initialisation of main diagonal matrix (for overlap values)
613    o tools/build_options:
614      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
615        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
616      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
617        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
618        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
619        and use "-devel" testreport option for standard testing on baudelaire.
620    o pkg/grdchk:
621      - Assume that all gradient-check position are within the same tile
622        corresponding to global indices (iGloTile,jGloTile) and that
623        positions (i,j indices or nbeg) are local to this tile;
624      - set tile local-indices and proc. number according to tile global-indices;
625      - remove grdchkwhichproc from namelist (retired param);
626      - send adjoint gradient to all procs so that all procs print it to STDOUT;
627      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
628    o adding package bbl (Bottom Boundary Layer)
629      description in MITgcm/pkg/bbl/bbl_description.tex
630      example/test experiment in MITgcm_contrib/bbl
631    o adjoint verifications
632      - changed 5 experiments to multi-tiles
633        * global_ocean.90x40x15
634        * obcs_ctrl
635        * offline_exf_seaice
636        * tutorial_dic_adjoffline
637        * tutorial_tracer_adjsens
638        changed reference output for those that crossed tile boundaries
639        (changed choices of gradient check positions)
640      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
641      - temporary bug fix in grdchk_loc.F for obcs
642    o genmake2 & testreport
643      - add target "obj" (just for OBJFILES files) to Makefile;
644      - add option to specify FEXTRAFLAGS on command line.
645    o pkg/mypackage:
646      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
647    
648    checkpoint63a (2011/08/02)
649    o pkg/diagnostics (velocity potential):
650      - fix velocity-potential calculation when using OBCS: balance net inflow
651        at each level (new S/R OBCS_DIAG_BALANCE).
652      - fix some of the problems with OBCS in stream-function calculation.
653    o pkg/exf/exf_readparms.F
654      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
655        EXF_NML_OBCS) more consistent, so that you need not have these lists
656        in data.exf when they are not used.
657    o optim/optim_readdata.F:
658      - add some output about obcs variables that might help debugging
659      - add a check about nvarlength
660    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
661    o pkg/diagnostics (velocity potential):
