4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
8      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
9        conductive heat flux F_c , and add it explicitly when updating tsurf as
10        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
11        so that now F_ia has a consistent meaning through the entire routine.
12        This causes differences at truncation level: update output of fwd exp.
13        global_ocean.cs32x15.seaice.
14    o pkg/seaice:
15      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
16        of arrays, sign/direction of fluxes; no effect on results.
17      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
18        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
19        note: this should have been done before changing celsius2K default.
20      - to keep results unchanged, add back old value of celsius2K in verification
21        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
22      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
23        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
24        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
25        freezing temp is consistent with value in seaice_growth.F ; this causes
26        differences at machine truncation level: update lab_sea AD output (3/4).
27    o pkg/seaice:
28      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
29        and climsst/sss even when using seaice (to prevent calculation that might
30        use SST on land); does not affect any verification exp.
31      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
32        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
33    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
34      over land (non-legacy code)
35    o vectorize salt_plume package:
36      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
37      - this code computes plumebk everywhere (also over land), thus requires
38        code to avoid divisions by zero and catch the case of kLev=Nr.
39      - efficiency of salt_plume_frac is still sub-optimal
40    o tools (genmake2):
41      - fix makefile NAME specification (option: -makefile NAME) by adding
42        "-f $MAKEFILE" in few places where it was missing including makedepend
43        command (contribution from Paul).
44    
45    checkpoint63i (2012/01/24)
46    o model/src:
47      - add factorized versions of some EOS code to find_rho.F,
48        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
49    o model/src:
50      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
51      - change default celsius2K from 273.16 to 273.15
52      - to keep results unchanged, add back old value of celsius2K in verification
53        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
54         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
55    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
56      to make TAF generate vectorizable code
57    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
58       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
59       have flags that do this more efficiently.
60    o pkg/diagnostics/diagstats_calc.F
61      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
62    o pkg/obcs (with exch2):
63      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
64        and remove code (in obcs_readparms.F) which was based on EXCH of indices
65        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
66    o pkg/exf and seaice exp:
67      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
68        so that switching off area & heff advection flags does not affect results.
69      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
70      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
71        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
72        results of verification experiments: 1D_ocean_ice_column(fwd),
73        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
74        and offline_exf_seaice (all 4).
75    o pkg/seaice:
76      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
77        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
78      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
79        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
80        not multi-dim advection;
81      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
82        SHORTWAVE_HEATING #undef.
83    o optim: make Makefile more robust (?)
84    o pkg/obcs:
85      * fix treatment of obcs_read_pickup for TAF
86    o pkg/shelfice:
87      * add missing initialisation of num_shifwflx
88      * new adjoint verification exp. for isomip
89      * change Prandtl and Schmidt numbers from generic formulations
90        (in terms of model diffus. and visc.) to separate runtime
91        parameters, with Holland and Jenkins (1999) default values.
92    o pkg/exf (interpolation):
93      - extended input field (2 rows) near the N & S poles:
94        * fill in with the symetric value (when even Nb of data in longitude)
95        * add average value at the poles only for scalar quantities ; for vector
96          component interpolation, skip the averaging and keep duplicated values,
97          unless the 2 components have same location (uvInterp=T) in which case
98          interpolate the 2 components together using S/R EXF_INTERP_UV.
99      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
100        together: this allows to account properly for local orientation when
101        averaging at N & S pole.
102      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
103        exf-interpolation near N & S poles. Undef by default.
104      - add debug check/print on 1rst iter if debugLevel >=2.
105    o pkg/exf:
106      - change masking flags definition (no longer "parameter"), put them in
107        common block and set them in S/R EXF_INIT_FIXED.
108      - change recognized masking flag from s,u,v to c,w,s since the mask
109        to use (maskC,W,S) depends on position on model grid and has little to
110        do with scalar/vector difference; fix masking if using P-coordinates.
111      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
112        and update results of exp. global_with_exf (x2).
113      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
114    o pkg/obcs
115      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
116    o pkg/exf (interpolation):
117      - assume periodicity in X only if input field cover full longitude range.
118      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
119        and should vectorise).
120      - fix input lat of the 2 added row (in case we provide N.pole data).
121    
122    checkpoint63h (2011/12/30)
123    o pkg/seaice:
124      - change declaration of UVM from _RL to _RS in order to get B-grid
125        uIce,vIce monitor when _RS = real*4
126    o pkg/offline:
127      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
128      - compute vertical velocity if not read from file (switch on exactConserv
129        & staggerTimeStep);
130      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
131    o verification:
132      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
133        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
134        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
135      - update output of exp. global_ocean.cs32x15.viscA4 after changing
136        grid-file angles (used here for coriolis-3d);
137      - remove (or gzip) few files not needed to run fizhi-cs experiments.
138    o pkg/exf (vector interpolation):
139      - rotate vector component toward local grid-axis orientation using grid-angles
140        (stored in GRID.h) instead of locally computed rotation angle; keep old code
141        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
142    o pkg/seaice:
143      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
144        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
145    o pkg/PKG_OPTIONS.h files:
146      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
147        outside of the #ifdef ALLOW_THISPKG / #endif block.
148      - update verification/*/code/PKG_OPTIONS.h files.
149    o add a verification experiment (offline_exf_seaice/input.seaice) that test
150      the B-grid LSOR solver
151    o pkg/seaice: sort out emissivity and long wave radiation step 2:
152      - add emissivity for snow and ice as new run-time parameters
153        (unfortunately) that default to the corresponding exf values; this
154        changes results in most verification experiments so that for backward
155        compatibility these parameter have to be set explicitly to inconsistent
156        values (ugly);
157      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
158        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
159        until we agree how to handle this bug properly
160    o pkg/exf (interpolation):
161      - add a set of run-time param ({inputfield}_interpMethod), one for
162        each interpolated input field, to select the interpolation method
163        with a value of zero switching off the interpolation;
164      - print interpolation parameters to standard output;
165      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
166        (to use instead runoff_interpMethod=0 in data.exf).
167      - simplify default setting of interpolation parameters (for all fields,
168        set position to match model grid cell-center position, leading to trivial
169        interpolation in case of regular Lat-Lon grid) and fix for the case of
170        non-uniform delY.
171    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
172       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
173       this factor is absolutely required, because the lw exitance (= out-going
174       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
175       where the reflectivity rho = 1-emissivity for conservation reasons. Once
176       this is established, we can remove the CPP-Flag (if we want to).
177    o pkg/seaice:
178      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
179        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
180      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
181        what the name implies (and not emissivity*BoltzmannConstant), this means
182        the old default value of 5.5e-8 now means
183        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
184        S/R exf_readparms
185      - FV-discretization of the B-grid LSOR solver, turn on with
186        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
187        of the calling routine dynsolver, so that B and C-grid code look a
188        little more alike.
189      - fix index bugs in ostres.F (B-grid code)
190    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
191    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
192      default for SEAICE_emissivity, if useEXF; requires setting a wrong
193      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
194      backward compatiblity
195    o model/src: use sigmaR in calc_ivdc
196    
197    checkpoint63g (2011/12/16)
198    o pkg/seaice/seaice_growth.F:
199      fix heat conservation of the coupled ocean-seaice system.
200      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
201      solid vs liquid water treatment is resolved via QNET.
202    o pkg/seaice/seaice_growth.F:
203      add missing term for sublimation in saltFlux, which was breaking conservation.
204    o pkg/seaice/seaice_model.F:
205      Remove this patholigical case treatment in evolution branch,
206      where it is un-necessary and breaks conservation.
207      Update global_ocean.cs32x15/results accordingly for
208      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
209    o model/src:
210      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
211      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
212    o pkg/obcs:
213      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
214      tendency for temperature and salinity that is then applied to update
215      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
216      horizontal advection and diffusion contributions on the boundary (in
217      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
218      removing the mask in S/R timestep_tracer. The advantage of this approach is
219      that the updated tracer values include contributions from the surface
220      forcing and vertical diffusion.
221      This modification changes exp4.stevens because of vertical diffusion.
222    o model/src:
223      change non-curvilinear grid setting to also work with exch2 + blank tiles:
224      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
225        face dimensions.
226      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
227        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
228        and INI_SPHERICAL_POLAR_GRID.
229      change test-experiment global_ocean.90x40x15:
230      - split the domain in many more tiles (9x4 tiles of 10x10 each);
231      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
232      - update results of both test (std & dwnslp).
233    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
234       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
235    o model/src:
236      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
237        and fix initialisation when using sigma-coords.
238    o model/src:
239     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
240       to their current value at the beginning of forward_step.F": add a new run-time
241       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
242     - set doResetHFactors=T in the following test exp:
243        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
244        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
245        and tutorial_global_oce_in_p (nonLinFS in p)
246    o pkg/ecco
247      - added IES cost term
248    o verification/advect_xz
249      - scale down the depth by 1/100 (from 200 km to just 2.km)
250      - add secondary test using divergent flow, r-star and implicit vertical advection.
251      - add note (check_conserve_TS.txt) and matlab script to check global
252        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
253    o pkg/rbcs:
254      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
255    o pkg/obcs (Stevens BCs):
256      - fix various problems in the phase speed computations of the Stevens
257        boundary conditions:
258        - sign error for western and southern boundaries,
259        - time tendencies were underestimated by factor of dTracerLev and some just
260          zero (for multidim advection schemes) -> now estimate time tendencies
261          from difference between previous (n) time level and the one before (n-1);
262          this requires storing a field per tracer per boundary, also in the pickup
263          files.
264        - replace deltaTmom in cflMer/Zon computation with dTracerLev
265        - set default phase velocity to cflMer/Zon
266      - update verification experiment exp4.stevens
267    o pkg/generic_advdiff (implicit_r):
268      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
269        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
270      - fix implicit vertical diffusion or advection with NonLin FreeSurf
271        (was using current recip_hFacC instead of future recip_hFacC): set future
272        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
273        solver S/R ;
274      - fill diagnostics of vertical advective fluxes (computed from tendency)
275        when using implicit vert. advection;
276      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
277         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
278         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
279         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
280    o pkg/diagnostics:
281      - add diags for T & S tendency which goes through Adams-Bashforth.
282    
283    checkpoint63f (2011/11/30)
284    o pkg/obcs/obcs_calc_stevens.F:
285      - join some loops to reduce number of if-statements
286      - fix a bug in code for northern and southern boundaries.
287    o pkg/seaice/seaice_init_varia.F
288      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
289        caused zero ice-velocities for the B-grid code
290    o pkg/seaice/seaice_init_fixed.F
291      - fix a bug in the initialisation of the second metric terms
292        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
293      - this affects all seaice configurations with useCurviLinearGrid = .true.
294        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
295        = .true. (default)
296      - the only verification experiment affected is global_ocean.cs32x15:
297        icedyn, seaice, and seaice_dynmix (AD)
298    o pkg/thsice/thsice_diagnostics_state.F
299      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
300        not contain garbage that can lead to surprises in diagstats_calc.F
301    o model/src:
302      - move bi,bj loops inside INTEGR_CONTINUITY ;
303      - call INTEGR_CONTINUITY directly from forward_step.F
304        (previously called from momentum_correction_step.F)
305      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
306        forward_step.F and pkg/ecco/the_main_loop.F
307    o model/src/do_oceanic_phys.F:
308      - reset addMass to zero only if useICEFRONT ;
309      - separated k-loop for rhoInSitu calculation ;
310      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
311        and at constant T,S (= WdRHOdP);
312      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
313        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
314        transport of locally-referenced potential density);
315        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
316    o gluemnc:
317      - replace ncrcat with ncks when adding variables to *.glob.nc
318      - change the way variables without record dimensions are handled so that
319        files that have variables with and without record variables can be glued:
320        add a record dimension with a new unique name to be able to differentiate
321        between variable with and without a-prior record dimensions. Remove
322        this record dimension before adding the variable to the *.glob.nc file.
323        This procedure automatically works also for grid.*.nc files that do not
324        have any record dimension.
325    o verification/cpl_aim+ocn:
326      - generate new reference output on baudelaire (gfortran, mpich2) (previously
327        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
328    o pkg/obcs/obcs_calc_stevens.F:
329      - add code for northern and southern boundaries.
330      - reorder some loops to save some operations and so that drFBar can be scalar
331    o model/src:
332      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
333        truncation) and add diagnostics for Adams-Bashforth tendency increment.
334      - update test-exp. AD output:
335        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
336      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
337        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
338        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
339        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
340        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
341        tutorial_plume_on_slope.
342    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
343      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
344      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
345      does not even come with an F77 compiler anymore, this should not be
346      a limitation
347    
348    checkpoint63e (2011/11/06)
349    o pkg/seaice adjoint of LSR:
350      - substantially rework STORE dirs.
351      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
352        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
353        and only perform SOLV_MAX_FIXED adjoint iters.
354        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
355        always goes to same record, meaning that the last forward field will be
356        the one used in the adjoint - an approximation.
357      - now produces non-zero LSR-related gradients, and acceptable gradients for
358        An's zonal (x-z) test case (to be checked in)
359      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
360        (but these are screwed up by the thermodynamics in the first place);
361        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
362        output_adm.txt also reflects changes to seaice_lsr
363      - global_ocean.cs32x15:
364        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
365          (output_adm.seaice.txt was updated)
366        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
367          (output_adm.seaice_dynmix.txt)
368    o test-exp. exp4+stevens:
369      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
370    o pkg/seaice (lsr solver):
371      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
372        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
373      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
374      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
375        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
376      - compute (with new S/R) and print initial (+ free-driff sol. if available)
377        and final residual of linearised system.
378    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
379      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
380    o pkg/obcs: Stevens BCs (still only for east and west)
381      - fix Stevens BCs by using intermediate velocities of previous
382        time step as "baroclinic" contribution rather velocity of one grid cell
383        inside the boundaries; more consistent but makes the entire treatment
384        more complicated, requires new pickup files and two new S/Rs:
385        obcs_copy_uv_n and obcs_save_uv_n
386        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
387        (undefined by default)
388      - silently move computation of some grid factors into separate loops to
389        save some recomputations
390      - add a hack for non-linear free surface
391      - add a verification experiment to exp4 that tests this code
392    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
393    
394    checkpoint63d (2011/10/25)
395    o pkg/obcs + seaice-dynamics:
396      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
397        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
398        values (consistent with an implicit method).
399      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
400        return to older implementation (same results as before); note that none of
401        the "experimental" OBCS_SEAICE options are implemented in the new version.
402      - switch test exp. seaice_obcs to use new version (update output).
403    o pkg/seaice:
404      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
405      - add parenthesis in Water-Ice drag calculations (evp & lsr);
406      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
407        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
408      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
409        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
410    o pkg/layers:
411      - Include potential density as new coordinate (Thanks to David Munday)
412    o pkg/dic:
413      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
414        carbonate computation/output to CALC_PCO2_APPROX
415    o pkg/generic_advdiff
416      - make TAF generate code that vectorizes:
417        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
418    o model/src:
419      - improve vectorization also for adjoint code of
420        solve_tridiagonal and solve_pentadiagonal. As this requires up to
421        5 new 3D-fields, this code is only turned on for the combination of
422        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
423        for singular matrix check (only for TARGET_NEC_SX).
424      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
425        ALLOW_AUTODIFF. This flag now needs to be set outside of
426        solve_tri/pentadiagonal.F
427    o pkg/exf:
428      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
429        optional namelist EXF_NML_OBCS).
430      - add many debug-print (to trace down where pkg/cal error msg comes from)
431    o pkg/mom_vecinv/mom_vi_hdissip.F
432      - rearrange loops so that vectorization is improved and in particular
433        the adjoint routine vectorizes. The code is a little longer now, but I
434        think easier to read.
435        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
436    o pkg/seaice:
437      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
438    o pkg/exch2:
439      - alternative code (without tile x tile matrix) for cumulated (global) sum;
440        used as default; keep using matrix version in adjustment.cs-32x32x1.
441    o tools/build_options:
442      - after merging some MPI and/or multi-threads specific optfiles so that
443        the modified default optfile support both built (using genmake2 -mpi
444        for the MPI built, using genmake2 -omp for OpenMP built),
445        move now obsolete optfiles to tools/build_options/unsupported/
446       (add copy of email sent to support list in doc/optfiles_changes.txt)
447    
448    checkpoint63c (2011/09/28)
449    o pkg/ebm:
450      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
451        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
452    o pkg/seaice (SItracer pickup)
453    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
454      To be done:
455      - thorough testing of missing fields in S/R seaice_read_pickup
456      - thorough matching between generic tracers and specific fields used
457        (e.g. volume-weighted age, area-weighted age, salinity, ...)
458    o pkg/grdchk:
459      - all procs calculate and print finite-difference gradient (for testreport)
460      - change description output used by testreport;
461      - AD testing: also compare and report Finite-difference gradient;
462        => update all output_adm*.txt
463    o test exp. global_ocean_ebm:
464      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
465        and turn on exactConserve; update (fwd) output.
466    o pkg/seaice (LSR):
467      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
468      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
469        * identical results with non-CS topology (but save up to half of EXCH calls)
470        * no much changes in cs-32 verification tests since no ice at face edges
471         (differences due to convergence criteria, since nb of iterations changed)
472        * expect some differences on lat-lon-cap grid.
473        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
474    o pkg/exch2:
475      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
476        many tiles); until alternative coding is added, just add a stop.
477    o pkg/kpp:
478      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
479        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
480    o optfiles:
481      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
482        into corresponding standard one, which now support different build:
483        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
484      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
485    o pkg/obcs (seaice):
486      - add missing EXCH for uIce,vIce after applying OBCS;
487      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
488        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
489        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
490      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
491      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
492        and eedata.mth for MPI and mutlti-threaded testing.
493    o pkg/flt:
494      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
495      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
496      - fix pickup and trajectories + profiles output with multi-threads;
497      - add parameter to select group of fields to write along trajectory and
498        profile (default unchanged);
499      - only call PORT_RAND* function when flt_noise <> 0;
500      - add multi-threaded test for verification exp. flt_example.
501    o eesupp/src:
502      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
503      - USE_OMP_THREADING: check that number of threads (from eedata) matches
504        actual number (from env.var. setting).
505    o pkg/ebm:
506      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
507      - add multi-threaded test for verification exp. global_ocean_ebm
508    
509    checkpoint63b (2011/08/29)
510    o pkg/ebm:
511      - fix sign of runoff;
512      - update directly forcing fields (Qnet,EmPmR) to use standard
513        external_forcing_surf.F (remove ebm_forcing_surf.F);
514      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
515      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
516        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
517      - update global_ocean_ebm parameters file data and update output (fwd+ad).
518    o verification/matrix_example:
519      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
520        MPI and mutlti-threaded testing.
521    o pkg/matrix:
522      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
523      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
524      - fix for multi-threaded (remove DATA statement);
525      - use standard DIFFERENT_MULTIPLE function;
526      - add MATRIX_OPTIONS.h
527    o verification/matrix_example:
528       To allow to split the domain in several tiles, change the domain size
529        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
530        Western side) of land points.
531    o (*_)write_pickup:
532      - fix few bugs in mypackage_read/write_pickup.F
533      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
534        array of length 1 (was caught by compiler syntax-check).
535    o pkg/diagnostics (velocity potential solver):
536      - fix initialisation of main diagonal matrix (for overlap values)
537    o tools/build_options:
538      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
539        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
540      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
541        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
542        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
543        and use "-devel" testreport option for standard testing on baudelaire.
544    o pkg/grdchk:
545      - Assume that all gradient-check position are within the same tile
546        corresponding to global indices (iGloTile,jGloTile) and that
547        positions (i,j indices or nbeg) are local to this tile;
548      - set tile local-indices and proc. number according to tile global-indices;
549      - remove grdchkwhichproc from namelist (retired param);
550      - send adjoint gradient to all procs so that all procs print it to STDOUT;
551      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
552    o adding package bbl (Bottom Boundary Layer)
553      description in MITgcm/pkg/bbl/bbl_description.tex
554      example/test experiment in MITgcm_contrib/bbl
555    o adjoint verifications
556      - changed 5 experiments to multi-tiles
557        * global_ocean.90x40x15
558        * obcs_ctrl
559        * offline_exf_seaice
560        * tutorial_dic_adjoffline
561        * tutorial_tracer_adjsens
562        changed reference output for those that crossed tile boundaries
563        (changed choices of gradient check positions)
564      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
565      - temporary bug fix in grdchk_loc.F for obcs
566    o genmake2 & testreport
567      - add target "obj" (just for OBJFILES files) to Makefile;
568      - add option to specify FEXTRAFLAGS on command line.
569    o pkg/mypackage:
570      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
571    
572    checkpoint63a (2011/08/02)
573    o pkg/diagnostics (velocity potential):
574      - fix velocity-potential calculation when using OBCS: balance net inflow
575        at each level (new S/R OBCS_DIAG_BALANCE).
576      - fix some of the problems with OBCS in stream-function calculation.
577    o pkg/exf/exf_readparms.F
578      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
579        EXF_NML_OBCS) more consistent, so that you need not have these lists
580        in data.exf when they are not used.
581    o optim/optim_readdata.F:
582      - add some output about obcs variables that might help debugging
583      - add a check about nvarlength
584    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
585    o pkg/diagnostics (velocity potential):
586      - fix mask for OBCS (still problems in stream-function with OBCS);
587      - add specific parameter (default = main code CG2D params) for solver;
588      - in case of poor convergence, use solution corresponding to lowest residual.
589    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
590      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
591      and should be avoided where possible.
592    o model/src (rStar):
593      - include r* effect on reference-state (PhiRef) in totPhiHyd
594        (so that it's really the potential anomaly at the cell center);
595        affect solution only if z* with full pressure in EOS.
596      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
597        update output (because of z* in totPhiHyd and viscA4 changes);
598      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
599        @ constant r) until interpolation at constant r is implemented.
600    o pkg/diagnostics
601      - fix RCENTER diagnostics in case cell center is not at interface middle
602    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
603      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
604      that THETA and SALT are "conservative temperature" and "absolute
605      salinity"
606    o pkg/ctrl
607      - fix computation of endrec in s/r ctrl_init_rec
608      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
609    o pkg/seaice/seaice_growth.F
610      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
611        remove then obsolete STORE directives
612      - fix STORE directives for tice and tices, so that only the
613        appropriate part of the fields are stored (and not the entire
614        field); update global_ocean.cs32x15.seaice AD output.
615      - cosmetic changes: adjust CPP flags and indentation for better
616        legibilty
617    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
618      Chris Wilson)
619    o pkg/gmredi:
620       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
621       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
622    
623    checkpoint63  (2011/07/11)
624    o pkg/exch2:
625     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
626     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
627       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
628       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
629    o pkg/diagnostics:
630     - deal with pairs of post-processed diags which are computed together; in
631       particular, re-order list of diags within 1 file to save 2nd computation.
632     - add S/R to compute velocity stream-function (called after velocity-potential
633       calculation) from divergence free transport -> new diagnostics "PsiVEL".
634     - add parameter to select grid-point location where PsiVEL == 0.
635    o eesupp/src:
636       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
637       (specific S/R needed with exch2 topology - for now, just print an error msg)
638    o pkg/shelfice
639     - Implement friction velocity-dependent transfer coefficients following
640       Holland and Jenkins, JPO, 1999
641       Original code by M. Losch with small modifs.
642       Enable with CPP option SHI_ALLOW_GAMMAFRICT
643       and runtime flag SHELFICEuseGammaFrict
644    o verification lab_sea & global_ocean.cs32x15:
645     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
646       does not miss some dependencies (but is slower) and also works with many files
647       (default makedepend limitation for AD built).
648     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
649    o pkg/diagnostics:
650     - add run-time parameter "useMissingValue" (def=False) to fill land-point
651        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
652       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
653     - Extend the use of "missing_value" setting from data.diagnostics for the case
654       of counter-diagnostics (where fraction-weight is zero). This applies both to
655       MNC and MDS output files.
656    o pkg/seaice/seaice_growth.F:
657      - add 'a priori' cap of latent heat flux based on actual mass considerations
658        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
659        non-legacy seaice_solve4temp.
660      - add diagnostic of the residual sublimation freshwater flux (the freshwater
661        flux taken from the ocean if the total actual latent heat fluxes exceed
662        the maximum)
663      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
664       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
665      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
666       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
667      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
668      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
669    o verification 1D_ocean_ice_column:
670       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
671       update results
672    o pkg/diagnostics:
673     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
674       which are not filled-up but computed from other diags ; In this case, the mate
675       diag points to the primary (filled-up) diag to used for post processing.
676     - Update Velocity-potential computation using post-processed diag framework.
677     ==> Change the ordering of fields and time-periods in MDS output file
678       when using periodic averaging: now writes one time record with the full set
679       of fields for this time period, then the next time reccord (it used to be
680       one field with the full set of time records then the next field).
681         Note: this is now similar to NetCDF (MNC) output file. <==
682    
683    checkpoint62z (2011/06/21)
684    o adjoint monitor:
685     - Add adjoint monitor output for packages exf, seaice
686       and update relevant testreport output
687    o pkg/seaice:
688     - re-order diags inits so that they appear in order in available_diagnostics.log
689     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
690       area/heff/hsnow preceeding thermodynamic growth/melt.
691     - modified diag: SIdA; output actual effect, as the description states.
692     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
693     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
694       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
695        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
696     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
697     - added diagnostics for seaice generic tracers (SItr*).
698     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
699     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
700     I. Fenty: 18-Jun-2011:
701     Minor changes to seaice package:
702     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
703        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
704       - Differentiated "regularization variables" from "floor variables"
705        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
706        * hiceMin became SEAICE_hice_reg (old hiceMin)
707          (with _reg meaning regularization variable)
708       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
709        so as to ensure energy conservation when going between phases
710      - A22 was not used anywhere
711     2) Changed regularization procedure for heffActual and hsnowActual to ensure
712        well-boundedness and smooth adjoint in seaice_growth.F
713     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
714        because the old regularization always set heffActual >= 0.05 cm
715     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
716        on AREA when HEFF > 0.
717      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
718        requiring that DISABLE_AREA_FLOOR *not* be defined
719     Affected verifications:
720      - 1D_ocean_ice_column (output.txt output_adm.txt)
721      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
722    o pkg/diagnostics:
723      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
724      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
725        (was _RL, now integer) with option = 0 to retrieve all levels.
726      - add pieces of code to compute velocity potential at each level (new diagnostics
727        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
728        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
729      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
730        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
731        and in diagnostics_fract_fill.F (do not need a valid pointer for the
732        diagnostics counter-mate); check that definition of counter-diagnostic
733        includes a valid counter-mate (in diagnostics_set_levels.F).
734    o model/src (rStar):
735      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
736        affect solution only if z* with full pressure in EOS;
737        update output of test-exp global_ocean.90x40x15.
738    o pkg/seaice:
739      - introduce siEps=1e-5 parameter
740      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
741      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
742      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
743        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
744        as well as ice cover age and ridging index (attached to AREA).
745        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
746        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
747        Up to SItrMaxNum=3 tracers can be used simultaneously.
748    o pkg/salt_plume:
749      -introduce SPsalFRAC run time parameter that sets the fraction of the
750       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
751       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
752    o model debug options:
753      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
754        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
755      - Refine debug-msg printing selection (3 new levels):
756        debugMode  : controls printing of debug messages (sequence of S/R calls).
757        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
758         debLevZero =  0 ; /* level of disabled aux. msg printing */
759         debLevA =  1 ; /* level of minimum  aux. msg printing */
760         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
761         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
762         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
763         debLevE =  5 ; /* level of extensive debug printing */
764        New debugLevel default: with default debugMode value (=F),
765          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
766          and if debugMode=T, default debugLevel = 4 (debLevD).
767        Relation with previous settings:
768         debLevB (=2) corresponds to former debLevA (=1)
769         debLevD (=4) corresponds to former debLevB (=2)
770        Note:
771         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
772         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
773            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
774      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
775        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
776    o pkg/obcs:
777      - change OBCSfixTopo default from True to False (should not change the results);
778        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
779    o pkg/thsice:
780      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
781        2nd layer seaice sublimation (unlikely to happen)
782      - use Interior mask for OBCS in thsice_advection.F (similar to what is
783        done in gad_advection & seaice_advection).
784    o adjoint:
785      bug fix spotted by Gael Forget:
786      seaice_advection and thsice_advection still had
787      legacy CPP options to avoid CS corner updates for adjoint
788    o pkg/seaice:
789      => Change some of the defaults (2011/05/29):
790         - change SEAICEuseFluxForm default (from False to True)
791         - change DIFF1 default (from 0.004 m/s to 0. m/s)
792         And print warnings if DIFF1 is not set in data.seaice and centered
793          avection scheme is used without any diffusion.
794      also:
795      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
796      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
797      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
798        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
799        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
800      update results of test exp.:
801         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
802             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
803             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
804         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
805         seaice_obcs: output (SEAICEuseFluxForm=T)
806      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
807          for standard fwd & AD lab_sea tests (to keep the same output).
808    o pkg/seaice/seaice_growth.F:
809      - use Ian Fenty's capping formulas for actual ice
810      thickness thoughout EVOLUTION branch.
811      - put treatment pathological case #2) in CPP brackets
812      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
813      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
814    o pkg/seaice:
815      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
816      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
817      also pass fac as a param, which can be 1. (to update the tendency
818      field) or the time step (to update the field itself).
819      - seaice_advdiff.F: for multidim, call seaice_diffusion with
820      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
821      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
822      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
823      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
824    o pkg/seaice:
825      diffusion with centered advection scheme (diffus.F & advect.F):
826      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
827        to just compute the laplacian of input-field.
828      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
829      - fix flux-form version in diffus.F to conserve tracer.
830      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
831       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
832    
833    checkpoint62y (2011/05/26)
834    o pkg/seaice:
835     - seaice_growth.F : in EVOLUTION branch, always include
836       a_QSWbyATM_cover in qnet (as it should be).
837     - verification/global_ocean.cs32x15 : update results accordingly
838       (output.seaice.txt output_adm.seaice.txt).
839    o pkg/seaice + obcs:
840     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
841       equivalent of assuming no tracer gradient outside the OB region.
842       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
843     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
844       after changes above);
845     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
846       only at OB location (instead of over a band of OLx width).
847    o pkg/seaice:
848     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
849       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
850    o pkg/obcs:
851      - split header file "OBCS.h" into 4 separated files:
852        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
853       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
854         (contain no conditional statement which depends on OBCS options).
855      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
856        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
857    o ctrl, cost, grdchk & autodiff pkgs:
858      - make options file more standard (like other {PKG}_OPTIONS.h file but
859        with AD_CONFIG.h); clean-up some of the included header files.
860    o pkg/obcs:
861      - do not mask tracer when applying OB (tracer == 0 could generate problems)
862      - apply tracer OB values to tracer field only at OB location (instead of
863        over a band of OLx width)
864      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
865      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
866        obcs_apply_tloc.F & obcs_apply_sloc.F
867    o obcs in model/src:
868      - call OBCS_APPLY_W only if NonHydrostatic.
869      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
870      - reset dEtaHdt and wVel to zero outside OB interior region ;
871      - leave tracer unchanged outside OB interior region: This has no effect
872        on the solution but just to prevent unrealistic tracer value outside OB.
873      - zero out velocity outside OB interior region: This has no effect on
874        the solution but just to prevent unrealistic velocity outside OB.
875    o obcs and non-lin free-surf:
876       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
877       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
878       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
879       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
880       update results of test-exp. exp4(nlfs).
881    o exp4 (nlfs) test-exp:
882       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
883       with NonLin-FreeSurf); update output.nlfs.txt
884    o obcs and 2d/3d solver norm:
885       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
886       and outside OB interior region (will allow to place OB further inside the
887       domain). Depending on the domain, can affects cg2d-Norm (previous
888       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
889       and cg3d-Norm (previous Norm was computed before canceling OB terms),
890       e.g. in tutorial_plume_on_slope.
891      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
892    o pkg rbcs:
893      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
894      - add capability to apply relaxation to horizontal velocity uVel & vVel.
895    o pkg/grdchk: add gradient check for control variable xx_shifwflx
896    o pkg/shelfice/shelfice_init_fixed.F
897      fix CPP-flag combinations
898    o pkg/seaice: Merge iceage code of Pierre Rampal
899      * update/change/correct ice age calculations
900      * add age updates for pathological cases
901      Probably needs more testing...
902    
903    checkpoint62x (2011/05/13)
904    o pkg/mom_vecinv:
905       high-order vorticity scheme: use interior masks (maskInW & S)
906       to zero-out (outside OB) gradient of vorticity.
907    o verification exp.:
908       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
909       hs94.128x64x5 and seaice_obcs ; update results.
910    o pkg/obcs:
911      fix bug in OBeta for YZ sections in obcs_exf_load.F
912    o pkg/ctrl, pkg/shelfice, and optim:
913      - add new control variable xx_shifwflx (fresh water flux underneath ice
914        shelves). This is almost as tedious as obcs-ctrl, because the
915        variables needs its own mask.
916      - add a cost function term that penalizes the deviation of xx_shifwflx
917        from the first guess (zero) in analogy to other control variables
918    o pkg/shelfice:
919      - start basic adjoint
920    o pkg/ctrl:
921      - remove extra 2D field "for good measure" when initializing in
922        ctrl_set_globfld_[xy/xz/yz].F
923      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
924      - improve error messages in ctrl_set_unpack_*
925    o OBC implementation in momentum:
926       use interior masks (maskInC,W & S) in momentum S/R:
927       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
928       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
929       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
930       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
931       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
932        (and also with Leith/Smagorinsky harmonic-viscosity).
933       Update output of experiment dome and exp4 (+nlfs).
934    o exp4 test-exp:
935      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
936        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
937        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
938        time-varying OB at Western-side for wVel (NonHyd); update output.
939      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
940        and biharmonic-viscosity ; also use prescribed time varying OB.
941    o pkg/obcs:
942      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
943    o model/src:
944      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
945      - initialise startTime & nIter0 with unlikely values: allows to set one
946        from the other without ambiguity.
947    o seaice_obcs test-exp.:
948      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
949    o pkg/obcs:
950      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
951        no longer needed with maskInC,W,S in pkg/generic_advdiff.
952    o pkg/seaice:
953      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
954        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
955      - fixed bug in the initialization of sea ice salinity variable HSALT
956        in seaice_init_varia.F  (removed dependence on ICE2WATR)
957    o fizhi-cs test exp.:
958       switch reference output convention for these 2 non-standard test-exp,
959        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
960          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
961       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
962    o model/inc:
963      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
964        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
965    o pkg/seaice:
966      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
967    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
968      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
969        and initial HSALT
970    
971    checkpoint62w (2011/04/26)
972    o pkg/mom_fluxform:
973      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
974      - use parameter "sideDragFactor" in no-slip BC side-drag part.
975      - update output of exp. global_ocean.90x40x15
976    o pkg/mom_vecinv:
977      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
978    o update seaice exp.:
979      use more consistent parameter values (remove "backward compatability only":
980       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
981      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
982       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
983    o update test-exp global_ocean.90x40x15:
984      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
985      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
986      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
987      o turn on zStar & viscA4 in standard set-up (dir input/)
988        and update output files: output.txt & output.dwnslp.txt
989    o new AD-test experiment: obcs_ctrl
990      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
991    o pkg/dic:
992      fix two bugs in handling water vapour pressure in carbonate chemistry
993      and air-sea fluxes. Found by Val Bennington and Galen McKinley
994      (add DIC Option = WATERVAP_BUG to recover old results)
995      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
996    o adding allowInteriorFreezing option to check for water below freezing point
997      at depth and bring the negative heat anomaly to the surface level
998    o pkgs _fields_load:
999      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
1000      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
1001        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
1002        rbcs to get interpolation weights and time reccord number.
1003      - fix multi-threading in aim_fields_load.F
1004      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
1005    o external_fields_load:
1006      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
1007       interpolation weights) to use in a periodic time-series ; do not divide by
1008       time-step to convert to integer:
1009       - this fixes case where externForcingPeriod is not multiple of time-step
1010          (Thanks to Christopher L. Wolfe)
1011       - this fixes case where externForcingPeriod is an odd multiple of time-step
1012         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
1013      store index of time-record which is currently loaded:
1014       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
1015       - needed for the adjoint but not yet used because of extensive recomputations;
1016         (to be fixed soon)
1017    
1018    checkpoint62v (2011/04/02)
1019    o verification/1D_ocean_ice_column added to test Ian Fenty's
1020      pkg/seaice_growth.F modifications for improving sea ice code differentiability
1021    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
1022      (new velocity statistics after changing maskInW & maskInS definition)
1023    o pkg/generic_advdiff with OBCS:
1024      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
1025      equivalent to assumption of no tracer gradient outside the OB region.
1026      This will affect the results if using obcs+biharmonic diffusion.
1027      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
1028    o pkg/obcs:
1029      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
1030      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
1031      in Interior region. No impact on solution but affects Velocity monitor stats.
1032    o pkg/ptracers (adjoint)
1033      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
1034      tape file for each tracer
1035    o model/inc/src and pkg/autodiff: add parameters that allow to turn
1036      of parts of the adjoint code at run time. For now, there are only
1037      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
1038      parameters are set in data.pkg.
1039      This is the lazy coward's version of doing this, but still useful for
1040      debugging. In order to do it right, everything needs to be moved to
1041      pkg/autodiff.
1042    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
1043      the end; this fixes the adjoint balancing code for open boundaries.
1044    o pkg/ctrl:
1045      - change behavior of xx_${varname}period to be analogous to exf-conventions:
1046        xx_${varname}period =   0.,  means time-independent control part
1047        xx_${varname}period = -12., means one-year-periodic monthly control part
1048      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
1049        clean up ctrl_init a little, remove unused variables
1050      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
1051      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
1052    
1053    checkpoint62u (2011/03/15)
1054    o model/src:
1055      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
1056        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
1057      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
1058        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
1059    o pkg/ctrl/obcs/ecco:
1060      - remove obsolete, unused, and partially broken code:
1061        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
1062        ALLOW_CTRL_OBCS_BALANCE
1063      - put a stop statement into ecco/cost_obcsvol.F, but also add
1064        cost_obcsvol to ecco_ad_diff.list
1065    o pkg/ecco: fix counting cost function contributions for obcs (code
1066      by Matt M.) and diffkr for diagnostics
1067    o pkg/ecco, pkg/ctrl, pkg/grdchk:
1068      add cost penalty terms for initial uvel, vvel, eta controls
1069      and I/O for prior error files
1070    o pkg/mdsio:
1071       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
1072       (new argument) to check for tiled file in mdsioLocalDir : this fix the
1073       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
1074    o pkg/ctrl:
1075     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
1076       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
1077       unused and superfluous variables
1078     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
1079    o pkg/ecco
1080     - enable adjoint of Stevens OB
1081    o pkg/ctrl/ecco/grdchk:
1082      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
1083        Fortunately, we do not have any tests for the numerous cpp-flagged
1084        option of "obcs as control parameters" so we will never know
1085        if this is an improvement (but at least now things compile).
1086      - remove an obsolete initialization from ecco_cost_init_barfiles.F
1087      - fix some problems within never used ifdefs to make the code compile
1088    o pkg/obcs:
1089     - Refine Interior mask definition to work with more complex OB (e.g.
1090       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
1091       read in Interior mask from file. Check if Interior mask is consistent
1092       with OB list of indices.
1093    o pkg/seaice
1094     - beginning code for a seaice tracer package,
1095       but currently only used for seaice age: SEAICE_AGE
1096       SEAICE_num = 4
1097       iTracer = 1: area-weighted ice age
1098               = 2: volume-weighted ice age
1099               = 3, 4: template for one-year vs. multi-year ice
1100       data.seaice has new namelist SEAICE_PARM03 for arrays related to
1101       SEAICE_num
1102    
1103    checkpoint62t (2011/03/05)
1104    o pkg/obcs:
1105     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
1106       then normal component. This ensures that the normal component is set
1107       correctly even when it conficts with tangential setting from an other OB.
1108       Affects results of test-experiment seaice_obcs: update the output.txt
1109    o pkg/obcs:
1110     - add code to monitor statistics of dynamical fields at OB.
1111     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
1112       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
1113       - change default: balance the Net inflow through all OB (instead of balancing
1114         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
1115     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
1116       to match Nortern OB inflow (OBCS_balanceFacN=0).
1117    o pkg/seaice:
1118     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
1119    o pkg/seaice (seaice_growth v 1.113):
1120     - reverting seaice_growth to v 1.111 in order to have code with exact bit
1121       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
1122       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
1123       runtime flag SEAICEareaFormula is kept but is inactive
1124    o model/src:
1125     - add new param to scale curvilinear grid distance and area when using
1126       a different sphere radius from the grid-files.
1127     - test/check multi-threads EXCH applied to local variable (cg2d_x)
1128    o adjoint:
1129     - enable adjoint of Stevens OB
1130     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
1131       (a bit delicate because of potentially modified adj. common block structure;
1132       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
1133    
1134    checkpoint62s (2011/02/15)
1135    o pkg/seaice (seaice_growth v 1.112):
1136     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
1137       computing the ice cover tendency from effective thickness tendencies. Include
1138       Ian Fenty's formula.
1139     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
1140       SEAICEareaFormula.
1141     - simplify notations for the various d_HEFF/d_AREA terms.
1142    o pkg/gmredi:
1143     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
1144       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
1145       add a verification test-run (front_relax.bvp) to test GM_useBVP.
1146    o pkg/seaice (seaice_growth v 1.111):
1147     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
1148     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
1149       also melt ice.
1150    o pkg/seaice:
1151     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
1152     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
1153    o pkg/cheapaml:
1154     - from Nico Wienders: New version of this package.
1155    o pkg/flt:
1156     - add CPP options to prevent floats to re-enter the opposite side of
1157       a periodic domain (default: keep periodicity)
1158    o pkg/gmredi:
1159     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
1160       (needed for multi-dim advection).
1161     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
1162    o model/src:
1163     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
1164    o tutorial_tracer_adjsens
1165     - extend to NLFS and replace maskC by hFacC
1166       (change reference output accordingly)
1167    
1168    checkpoint62r (2011/01/24)
1169    o testreport:
1170     - add option -deloutp (-do) to remove output file after successful run
1171     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
1172       extract exact list of procs from this file ; adjust COMMAND by
1173       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
1174    o pkg/ecco: replace old ineffective way of penalizing deviations from
1175      first guess (of obcs) with code by Matt Mazloff
1176    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
1177      exf/cal
1178      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
1179        and handle case of obcs?period == 0
1180        Not affected by these changes: There is still an inconsistency in
1181        the computation of start/endrec for the obcs variables for ALLOW_CAL
1182        defined (see comment by Menemenlis, 7-Mar-2003)
1183      - make S/R ctrl_get_gen_rec return something meaningful even if
1184        ALLOW_CAL is not defined
1185      - ctrl_getobcs?: simplify code so that it does not need to use
1186                       S/R exf_swapfields
1187    o testreport:
1188       allow to test MPI with different number of processors for each experiment:
1189       create file "SIZE.h.mpi" in each build dir.
1190       Note: update of "-command" argument not yet implemented.
1191    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
1192      alleviate the need for additional 3D tapes when using
1193      the non-inear free surface in the adjoint. This is done
1194      by adding an 'update' of hfacc etc. to their current
1195      value at the beginning of forward_step.F.
1196    o pkg/seaice
1197      seaice_lsr: move stress-divergence computations out of outer pseudo-
1198      timestepping loop
1199    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
1200      up, so that the calls of the ctrl_* subroutines are really at the end
1201      of the routine.
1202    o pkg/gmredi:
1203      allow to specify a 2-D horizontal map and a 1-D vertical profil
1204      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
1205    o pkg/seaice:
1206      move lsr iterations from seaice_dynsolver to seaice_lsr.
1207    o pkg/seaice:
1208      reduce memory footprint of seaice mutldim advection tapes,
1209      by using a 2D tape independent of the generic_advdiff ones,
1210      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1211    
1212    checkpoint62q (2010/12/29)
1213    o model/src:
1214      - check horizontal grid-spacing for unset or zero/negative values.
1215      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1216    o pkg/flt:
1217      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1218      - precision of input and output files set according to readBinaryPrec
1219        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1220      - initial float position from tiled file was not converted to index space
1221        (looks like a bug): fixed to make it similar to initial pos. global file.
1222    o global_ocean.cs32x15:
1223       change SIZE.h of AD set-up to get same tiling as with MPI.
1224       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1225    o model/src:
1226       add flag to control printing of domain fields (bathymetry, hFac ...) in
1227       ini_mask_etc (call to plot_fieds_xy*).
1228    o pkg/thsice:
1229       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1230       over the interior only + apply EXCH at the end (like with SEAICE advection).
1231    o pkg/mdsio:
1232      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1233        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1234      - change barrier call for safe multi-threads access to 3-D shared buffer.
1235      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1236      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1237        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1238    o pkg/flt:
1239      - add fourth-order Runge-Kutta integration
1240      - add basic exch2 support (only 1 facet supported so far!)
1241    o pkg/mdsio+rw:
1242      new S/R to read local (or tile independent) vector (read counterpart of
1243       mds_writevec_loc, and front-end write_glvec_rl/rs).
1244    o global_ocean.cs32x15: additional input_ad.seaice experiment
1245        that uses pkg/seaice rather than pkg/thsice.
1246        (using multidim advection for seaice)
1247    o towards more F95 syntax for array specification in namelist:
1248      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1249        of all verification experiments.
1250           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1251          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1252      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1253    o global_ocean.cs32x15: additional input.seaice experiment
1254        that uses pkg/seaice rather than pkg/thsice.
1255    
1256    checkpoint62p (2010/12/17)
1257    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1258        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1259    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1260        allow for use of multim. advection in seaice adjoint.
1261    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1262      - first attempt to close budgets by taking into account the freshwater
1263        flux implied by the sublimation of snow and ice. So far only the
1264        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1265        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1266    o eesupp/src:
1267      new S/R with new option (NML_EXTENDED_F77) to change array specification
1268      from F95 standard to commonly accepted extended F77 form.
1269      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1270      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1271      for less tolerant f77 compiler (e.g., pgf77, g77).
1272    o globalFiles:
1273      commented out in parameter file "data" since it's not safe with MPI
1274      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1275      in this case); no longer commented out in restart test (tst_2+2).
1276    o add adTapeDir to specify a special directory where adjoint tapes are
1277      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1278      and cannot be used together with mdsioLocalDir.
1279    o nesting pkgs:
1280      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1281      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1282      - add parameter files + utils dir + output from short run on beagle.
1283    o pkg/seaice:
1284        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1285    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1286      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1287    
1288    checkpoint62o (2010/11/25)
1289    o pkg/exf:
1290      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1291    o pkg/seaice:
1292      - seaice_ocean_stress: split a loop for better vectorization of the
1293        adjoint code
1294      - seaice_growth.F: fix bug in conservation of freshwater connected to
1295        capping of heff, put contribution into d_HEFFbyNEG
1296      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1297        by something more sensible (parameters that are what their name implies)
1298      - change some defaults, so that by default exf-parameters are used for
1299        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1300        to reproduce the old results, many data.seaice now contain funny values
1301        for cpAir and latent heat of sublimation
1302    o packages_readparms.F: move exf_readparms up in line so that
1303        exf-parameters are visible for other packages (e.g. seaice)
1304    o debugMode & debugLevel=2:
1305      - differentiate between debugMode & debugLevel=2:
1306        debugMode: controls printing of debug messages (sequence of S/R calls).
1307        debugLevel: controls printing of algorithm intermediate results and stats.
1308      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1309        => allows to print debug-stats without all sequence of call messages.
1310      - switch control of debug print from debugLevel to debugMode in many S/R.
1311    o pkg/obcs (obcs-sponge):
1312        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1313        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1314    o pkg/generic_advdiff:
1315      - record overlap minimum size for each advection scheme;
1316      - refine criteria on overlap minimum size;
1317      - check and stop (in gad_check) if overlap size is too small.
1318    o pkg/obcs:
1319      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1320        once, in ptracers_implicit.F)
1321      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1322        apply OB values when tile has OB)
1323    o model/src, coriolis setting:
1324      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1325        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1326        files (selectCoriMap=3) with any grid.
1327      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1328    o pkg/seaice/seaice_growth.F:
1329        a few cosmetic changes that reduce the number of lines of code
1330    o pkg/obcs: add boundary conditions following Stevens (1990)
1331      - the code follows old MOM/NAOSIM code
1332      - so far it is only implemented for the eastern and western boundaries
1333        and NOT for pTracers
1334    o pkg/rbcs:
1335      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1336        beginning of the first rbcs forcing period.
1337      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1338        offline package, i.e., one file per time, labeled by iteration number;
1339        deltaTrbcs sets the timestep with which the data was generated;
1340        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1341      - rbcsForcingCycle=0 makes forcing non-cyclic.
1342      - make arithmetic safe for negative times and odd forcing periods.
1343    
1344    checkpoint62n (2010/11/09)
1345    o pkg/seaice:
1346        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1347    o pkg/obcs:
1348       New S/R to copy tracer value from the OB location to narrow band region
1349        (width = same as overlap) beyond the OB: preserve OB value (needed for
1350        high-order scheme) which were overwritten by EXCH call if in overlap
1351        region. Applied to theta, salt, ptracer and advected seaice variables.
1352       With seaice: use maskInC in similar way as in gad_advection.F,
1353        in seaice_advection.F and advect.F.
1354       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1355        4th order Adv.Scheme. for pasive salt and ptracer.
1356    o tools/genmake2:
1357      - when looking for an optfile (not specified), only search for Fortran compiler
1358        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1359      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1360        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1361      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1362        an optfile, but otherwise default was just "cpp".
1363      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1364      - when "CC" is not set in the optfile, look for possible C compiler
1365        (instead of just setting CC=cc)
1366      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1367        => add a ".F" to ".o" rule for source files with no "#include" (such as
1368           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1369      - move gfortran before g77 in list of possible Fortran compiler (consistent
1370        with reference compiler switch from g77 to gfortran)
1371    o pkg/seaice:
1372      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1373        seaice_check that stops the model, when the CPP flag is used.
1374      o seaice_growth.F: make capping of ice volume conserving by returning the
1375        capped ice as freshwater to EmPmR. This does not change the verification
1376        experiments but will change runs where the capping is acutally active
1377    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1378      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1379         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1380         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1381    o tools/genmake2:
1382      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1383      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1384      - clean previous genmake log files before anything else.
1385      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1386        files only with "CLEAN" target (instead of "Clean");
1387    o pkg/generic_advdiff:
1388      Change OBCS in multiDim advection (gad_advection.F):
1389       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1390       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1391       which were applying future time-step OB values.
1392      This way, all explicit calculations use current-time-step OB values
1393       (simpler and more consistent).
1394      Affects results when set-up uses time-varying OBC and multi-dim advection;
1395       update output of experiment seaice_obcs.
1396    o pkg/seaice:
1397      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1398       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1399         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1400      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1401       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1402       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1403    o pkg aim (2010/10/26):
1404      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1405        formulation with obliquity, eccentricity, ... as run-time parameters,
1406      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1407        upward shortwave radition at the surface (all-sky and clear-sky).
1408    o pkg/obcs:
1409      - writing sections with globalFiles=T does not work: switch to tiled-files
1410        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1411      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1412      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1413    
1414    checkpoint62m (2010/10/21)
1415    o pkg/seaice: vectorize seaice_solve4temp.F
1416      - move iterations loops outside of i/j-loops
1417      - requires 2D arrays for TB and effConduct
1418      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1419        modified in this routine
1420      - a little bit of clean up, adjusting indentation, etc.
1421      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1422        performance and '**TWO' by '**2' (because TWO is a float),
1423        replaced ONE, ZERO
1424    o eesupp/src:
1425       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1426    o pkg/seaice/seaice_growth.F
1427      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1428      merging process. The merged routine has two branches, and one activates the 'evolution'
1429      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1430      In summary, here is what the '10/10 revision' did consist of
1431        part 1: seaice_growth.F revisions 1.71 to 1.75
1432          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1433            The emphasis here was on improving readability (e.g. by trying to use meaningful
1434            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1435        part 1.5:
1436          - revising the lab_sea experiment to make it a more useful (i.e. stable
1437            and representative of an actual model run). This was done by generating a
1438            (winter) pickup to start from, switching back the main experiment dynamic
1439            solver from evp to lsr, having one of the experiments use the free drift solution.
1440        part 2: seaice_growth.F revisions 1.76 to 1.85
1441          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1442          - Sorting out the various fields units and sign (set early on and reset at the end)
1443            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1444            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1445          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1446            and simplifying logical expressions to further improve readibility.
1447        part 3: seaice_growth.F revisions 1.86 to 1.89
1448          - Re-organize the blocks of code more logically.
1449          - Merging the '_if.F' pieces that add something new.
1450    o pkg/thsice:
1451      - vectorize thsice_solve4temp and thsice_get_exf.
1452        Problem: thsice_solve4temp has an unvectorizable statement that
1453        might also be problematic for TAF
1454      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1455        does not change the verifcation experiment, but will change all
1456        experiments that have this flag undefined (not tested in verification);
1457        a little reorganization to save a few 2D fields and recomputations
1458      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1459      - 2nd step:  fix some store dirs
1460        o seems to work somewhat, i.e. using ifort but not g77
1461        o likely cause are incomplete init. or recomputation
1462        o start verification/global_ocean.cs32x15/input_ad.thsice
1463    o pkg/obcs: add support for exch2
1464      - the position of the boundary and prescribed values are specified using
1465        a global domain with exch2 facets stacked
1466        - in x for N,S boundaries (like W2_mapIO=-1)
1467        - in y for E,W boundaries (so E,W boundaries do not overlap)
1468    o pkg/mdsio: add support for writing global sections with exch2
1469        file layout is as for obcs described above:
1470        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1471        - for y-z sections, facets are stacked in y
1472    o pkg/thsice:
1473       - change a few routines for better vectorization: thsice_albedo.F,
1474         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1475         not affected, but in particular the latter routine has changed
1476         dramatically (not necessarily easier to read now).
1477       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1478       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1479    o verification/lab_sea:
1480      - overhaul of the forward model experiments. The main motivation
1481        for this revision is that lab_sea has proven quite fragile (when
1482        changing the sea-ice code, and switching platforms) to a point
1483        when failures were very hard to attribute to specific code problems.
1484      - the suspected reason for this fragility is noise amplification by evp so,
1485        to start with, we decided to replace evp with lsr in the main experiment.
1486      - the input.lsr experiment thus became obsolete and was removed.
1487      - it was replaced with the input.fd experiment that uses an
1488        analytical "free drift" solution as the ice velocity field.
1489      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1490        will hopefully allow us to discriminate problems due to dynamic solvers
1491        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1492        us to test additional options, along with the salt plume package.
1493      - Finally a pickup was generated (at the end of a one year run) to
1494        make the tests more representative of an actual model run. Previously
1495        the tests starting point was a 1m thickness of ice everywhere.
1496    o pkg/seaice:
1497      - introducing S\R seaice_freedrift.F that compute the
1498        analytical solution to an approximate ice momentum
1499        equation (i.e. the simple stress/coriolis balance).
1500      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1501        of the free drift velocity field, and enable its use.
1502        To actually use the free drift solution as the model ice
1503        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1504    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1505    
1506    checkpoint62l (2010/10/04)
1507    o pkg/seaice:
1508      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1509      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1510       version (with USE_ORIGINAL_SBI undef);
1511    o add hooks for new packages OASIS, the package will follow
1512      (hooks exclude the seaice pkg for now)
1513    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1514      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1515      rather than mdsio_readvector.F/mdsio_writevector.F, within
1516      adread_adwrite.F to read/write adjoint-related tapes to disk.
1517    o eesupp and pkg/mdsio: ALLOW_WHIO
1518      Option to write/read 2D fields to files including tiles halos.
1519      The main purpose is for adjoint related "tape I/O".
1520      The secondary purpose is for debugging phases.
1521      A word on those rather specifically intended purposes.
1522      The code was meant to be stripped down to the bare minimum.
1523      Typically, there is a unique and basic mapping to the global
1524      buffer (tile by tile, then proc by proc, then level by level), and
1525      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1526      meant to generate user friendly outputs of various shapes and forms.
1527      Rather it is intended, for the knowledgeabale developers,
1528      to be largely independent of the many mdsio options, to allow
1529      outputs of tiles+halos in debugging phases and in adjoint runs,
1530      and to allow some flexibility in tuning (adoint) I/O depending on each
1531      file system behavior. With regard to tuning, most of the potential knobs
1532      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1533      to specify directories, to specify the typical size of I/O calls, etc.)
1534      are not yet included, and will be added if they prove useful.
1535    o pkg/seaice:
1536       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1537    o pkg/seaice:
1538       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1539       code (seaice_budget_ice_if.F) which enable to recover old standard
1540       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
1541       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
1542    o model/src (rStar):
1543       use simple average (not area weighted) of rStarFac at U,V point when using
1544       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
1545       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
1546    
1547    checkpoint62k (2010/09/17)
1548    o adjoint
1549       * changed verification/global_ocean.cs32x15 ; adjoint now tests
1550         Adams-Bashforth 3 + NLFS + RSTAR
1551       * some more modifs required for ECCO-GODAE v4
1552    o pkg/seaice
1553       add SEAICE_AGE_VOL option to use volume instead of area for
1554       integrating SEAICE_AGE
1555    o model/src:
1556       first check-in of sigma & hybrid-sigma coordinate code ; also includes
1557       non-linear free-surface parts ; but pressure-gradient not yet coded.
1558    o pkg/ptracers:
1559       option for ptracer to convert Salt Relax into additional EmP.
1560        tested in exp. global_ocean.90x40x15.dwnslp (update output)
1561    
1562    checkpoint62j (2010/08/25)
1563    o pkg/ggl90:
1564       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
1565    o pkg/dic: car_flux.F, phos_flux.F
1566      - reduce number of exp-calls in order to improve performance
1567      - clean up a little (replace fields by their macros, etc., fix
1568        typo in CPP-flag)
1569    o pkg/ggl90: minor changes
1570      - GGL90diffKrS was removed --> always use GGL90diffKr
1571      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
1572      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
1573        (commented out for now)
1574      - change in max/min operations to ensure that smoothing is ok
1575      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
1576      - always use diffKrNrT as background profile (i.e. never use diffKr field)
1577    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
1578    o pkg/dic:
1579      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
1580        vectorization
1581      - small bug fix in insol for the unlikely case of a cartesian grid
1582      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
1583        + now vectorize, which also removes adjoint recomputations;
1584        + replace integer maksp1 by _RL maskp1
1585        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
1586    
1587    checkpoint62i (2010/07/21)
1588    o pkg/flt:
1589      - with OBCS: stop floats which enter the OB region
1590    o model/src:
1591      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
1592        for implicit vertical advection.
1593    o pkg/seaice:
1594     - account for melting in seaice age evolution.
1595     - remove double counting of seaice ridging effect on seaice age.
1596    
1597    checkpoint62h (2010/06/18)
1598    o pkg/exch2:
1599     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
1600    o tools/genmake2
1601      - remove "-pdefault" option: redundant with the use of "packages.conf";
1602      - remove file pkg/pkg_default : set the default as a pkg group
1603        ("default_pkg_list") defined in pkg/pkg_groups;
1604      - fix for case pkg/pkg_depend is missing (was hanging before);
1605      - add option "-pgroups" to specify a different pkg_groups than the default.
1606    o verification/adjustment.cs-32x32x1:
1607       add a "minimal" set-up test (code_min & input_min) which only compiles
1608       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
1609    o tools/genmake2
1610      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
1611      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
1612  o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these  o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
