4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ecco:
8      - retire old codes to the Attic. The calls to retired
9        functions are left in a commented form in case they
10        ever need to be re-activated.
11      - ecco_check.F: issue warning if any old CPP option is
12        defined that corresponds to retired codes -- then stop.
13    o pkg/atm_compon_interf:
14      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
15        coupler: use last time-step value instead of average over cplSendFrq_iter
16        time-step, similar to what is done for seaIceMass.
17        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
18    o eesupp & genmake2:
19      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
20        <= remove until a fix is found for some ifort version on ia32 machine.
21    o pkg/seaice/seaice_evp:
22      - refine residual computation
23    
24    checkpoint65q (2015/11/18)
25    o pkg/seaice/seaice_evp:
26      - fix residual computations so that they no longer affect the actual
27        simulation code
28      - fix seaice_readparams to be able to actually set new parameters
29        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
30    o model/src:
31      - fix wrong truncation (single prec) from "FLOAT" function in expressions
32        like: deltaT*FLOAT(myIter) when myIter is large:
33         a) replaced by DFLOAT (if not seen by TAF);
34         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
35    o pkg/aim_v23:
36      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
37        when pickupSuff is set ; do write rolling pickups + at the end of the run.
38    o pkg/atm_ocn_coupler + ocn_compon_interf:
39      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
40        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
41        add corresponding call in DO_OCEANIC_PHYS.
42    o coupler pkgs:
43      Start a new way to set-up optionally-exchanged variables (previously, only
44       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
45       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
46       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
47       compononent param default can be set accordingly).
48      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
49       but rather applies to a group a fields (going both ways like for DIC)
50       and corresponds to an option of coupling config.
51      coupler (pkg/atm_ocn_coupler):
52      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
53        and read namelist directly (without eessup S/R calls) instead of
54        in the very un-flexible old way, 1 param per line, in fixed order;
55      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
56        cleanly in CPL_CHECK_CPLCONFIG
57      - add new coupling-exchange selectors (some not yet active) including
58        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
59                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
60      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
61        component ; called directly from coupler.F, after comp. registrations;
62      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
63         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
64          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
65      components (pkg/atm_ & ocn_compon_interf):
66      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
67        CPP header file in all pkg source files.
68      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
69        ATM/OCN_CHECK_CPLCONFIG;
70      - add error-counter to track errors (e.g., in "data.cpl") and to stop
71        cleanly in ATM/OCN_CHECK_CPLCONFIG;
72      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
73        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
74        before PACKAGES_READPARMS;
75      verification/cpl_aim+ocn/:
76      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
77        "data.cpl" for coupler (in input_cpl).
78    o eesupp/inc:
79      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
80        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
81        to always cumulate tile local-sum in the same order (still uses
82        MPI_Allreduce like standard code).
83      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
84        that are now identical to standard version (in eesupp/inc).
85    o pkg/shelfice:
86      - add SHELFICETransCoeffTFile for initializing spatially varying
87        heat and salt transfer coefficients
88    o pkg/atm_compon_interf & ocn_compon_interf:
89      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
90        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
91      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
92    o pkg/atm_ocn_coupler:
93      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
94    o pkg/rbcs:
95      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
96        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
97      - add a short report (to STDOUT) about RBCS-mask settings.
98    
99    checkpoint65p (2015/10/23)
100    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
101        there is no adjoint test for EVP, we don't know what it does to the adjoint
102        solution, but at least there are no more recomputation warnings left
103    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
104        a chance of giving the same results as a fully converged VP (JFNK) solver
105    o tools/adjoint_options/adjoint_diva:
106      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
107    o pkg/streamice:
108      - spotted bug in streamice_driving_stress using dyG where should have been dxG
109    o pkg/exf:
110      - remove STOP statement that prevented to use wind or (wind-)stress
111        interpolation for constant-in-time forcing fields (wind/stress period = 0).
112    o pkg/seaice:
113      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
114        5 additionals 2D fields and 6 new store directives
115      - change logic in seaice_readparms.F: EVP code can now be turned on in
116        various ways, setting SEAICE_deltaTev is no longer required,
117        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
118        or SEAICEaEVPcoeff
119    o pkg/shelfice/shelfice_thermodynamics.F
120      - redefining uLoc/vLoc to u/v, instead of 2u/v
121    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
122      - this is an intermediate state of a truely converging EVP that has
123        the potential of outperforming implicit VP methods, I do not recommend
124        using it yet.
125      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
126        and all parameters are hardwired
127      - for convergence it still requires very smooth regularisations, that means,
128        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
129        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
130        specific averaging appears to be required, still subject to tuning
131      - still needs cleaning and I need to turn parameter into runtime parameters
132      - add code to compute and print residuals of iteration, compile with
133        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
134    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
135      that entered with r1.54 on Sep04, 2015, -> update results
136    
137    checkpoint65o (2015/09/14)
138    o pkg/mom_vecinv & mom_common:
139      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
140        called from there.
141      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
142        allows to use Vector-Invariant form in deep atmos and anelastic formulation
143    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
144      and Koenig-Beatty+Holland (2012)
145      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
146      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
147      - requires an extra input argument for S/R seaice_calc_viscosities
148      - tensileStrength's depth dependence is different from Itkin et al. (2015)
149        (to be changed and played with, for now exponential)
150    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
151      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
152        by AREA according to Connelly et al. (2004), JPO.
153      - For EVP and the LSR solver, the implicit part of the drag term is
154        the only non-zero term in the denominator when there is no ice (which
155        prevented running the model with zero ice-ocean drag). If
156        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
157        (or zero main diagonals BU/BV) which need to be caught. A practical
158        consequence is that for open water, the momentum equation reduce
159        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
160        they happen to be zero, often leading to a non-zero solution over
161        open water.
162    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
163        efficient EVP method.
164      - introduce area-weighted averages for e12 (analogously to
165        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
166        remain, but also changing the order of terms in the previous average
167        changed the results as much) -> update experiment
168      - add SEAICE_DELTA_SMOOTHREG code
169      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
170        TEM-code
171      - adjust loop bounds so that only required fields are computed
172      - add new averaging code for zetaZ/deltaZ (again similar to
173        seaice_calc_viscosities.F), inactive by default for now (will change
174        results again), but will replace old code eventually
175    o eesupp/src:
176      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
177        to always cumulate tile local-sum in the same order
178        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
179        Still uses MPI_Allreduce (like standard code) but on array of tiles
180        and should be faster than GLOBAL_SUM_SEND_RECV code.
181      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
182        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
183      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
184         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
185         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
186         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
187         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
188    
189    checkpoint65n (2015/07/29)
190    o pkg/thsice:
191      - add a warning when used with pkg/aim but without updating SST
192        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
193    o pkg/offline:
194      - change where Offline-Fields are loaded, from load_fields_driver.F to
195        directly within FORWARD_STEP, just after updating iter number and time;
196      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
197        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
198       These changes allow:
199        a) to recover exactly on-line results using deltaToffline=deltaTClock,
200        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
201        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
202        time-step, both with GM & KPP files and with recomputing these fields;
203        b) no needs to switch on staggerTimeStep anymore;
204        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
205      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
206    o pkg/offline:
207      - change (rarely used) offset-iteration parameter to an offset time (in s):
208        can easily recover previous offset-iter effect by setting offset-time
209        (offlineTimeOffset) to offset-iter x deltaToffline;
210      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
211        in KPP as part of surface buoyancy forcing) in offline run.
212      - fix ptracers KPP non-local term in the case where KPP is re-computed.
213    o OpenAD
214      - Adding preliminary ggl90 test to OpenAD verification.
215        Config. with ggl90 currently diverges after 64 time steps
216        so will need more work to become more stable
217      - Adding preliminary kpp test to OpenAD verification.
218        required small tweakes in kpp_routines.F
219      - Merge and update from Krishna Narayanan's contrib area:
220        * Add one variable for preliminary OpenAD DIVA
221        * Add replacement time-stepping for OpenAD DIVA
222        * genmake2 flag -diva (but only for OpenAD; preliminary)
223        * required modifs for OAD_support
224        successful preliminary test for tutorial_global_oce_biogeo/
225    o pkg/seaice:
226      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
227      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
228        delta with a smooth function in s/r seaice_calc_viscosity
229        (no effect on EVP)
230      - rename local suffix "sqr" into "sq" for more consistent variable names
231    o pkg/seaice:
232        add new parameter SEAICE_deltaMin that is used ***only***
233        for regularizing Delta (and nothing else, like the parameter
234        which is also used for all sorts of things SEAICE_EPS).
235        Defaults to SEAICE_EPS for backward compatibility only.
236    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
237        the wrong key by inialising it before use -> fixes a recomputation
238        problem but does not fix the gradient
239    o pkg/layers:
240      - move resetting of flux arrays to outside the iLa loop
241        (this caused layers_diapycnal to not work with more than one layer coord.)
242      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
243    o pkg/layers:
244      - remove from common block 3D layers fields (used to diagnose transport
245        in tracer coords) and declare them as local arrays in layers_calc.F
246    o pkg/seaice:
247      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
248        in lab_sea forward experiment (changes results -> updated)
249      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
250    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
251       computations; for SEAICE_VECTORIZE_LSR
252      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
253        sweep to the outside,
254      - remove store directives and add "CADJ loop sequential" directives
255        in analogy to model/src/solve_tridiagonal.F
256      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
257        boundaries to yield more readable code. This has also the charming side
258        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
259        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
260        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
261        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
262        an additional option)
263       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
264       but the adjoint gradients (which are affected by this change) still explode.
265    o coupler (atm & ocn _compon_interf):
266      - avoid using Exch2 IO mapping if not suitable.
267    
268    checkpoint65m (2015/06/15)
269    o pkg/layers:
270      - clean-up old parameters setting (from Sep 2012):
271        + remove old parameters setting from common block (declared locally);
272        + stop if any old parameter is mixed with new parameters;
273        + check for valid or consistent parameter setting (e.g., layers_name)
274      - check that layers_bounds for Pot.Density are in the right range;
275        this is supposed to catch un-updated setting after recently shifting
276        potential density field "prho" by -1000 (now in "sigma" scale).
277    o pkg/layers:
278      - Added missing call to layers_fill for keeping track of tottend in
279        pkg/diagnostics/diagnostics_fill_state.F
280    o pkg/layers:
281      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
282        of diapycnal fluxes
283    o pkg/layers:
284      - reverted changes to interpolation to previous treatment; there
285        was never actually a problem
286    o pkg/layers:
287      - fix interpolation of layers tracers in the presence of partial cells
288      - add lots of new functionality to compute water mass transformation
289        (enabled by CPP flag LAYERS_THERMODYNAMICS)
290      - add new calls from main code (diags_oceanic_surf_flux.F,
291        thermodynamics.F, impldiff.F) and gad to save the necessary fields
292        for layers_thermodynamics calculations
293    o pkg/ptracers:
294      - add capability of stepping a passive tracer forward without advection
295        by setting PTRACERS_advScheme to 0.
296    o pkg/diagnostics:
297      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
298    o pkg/layers:
299      - shift potential density field "prho" by -1000 for density layer averaging so
300        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
301        Note that density bin boundaries (layers_bounds in data.layers) have
302        to be set accordingly (i.e., shifted, in sigma scale).
303    o pkg/layers:
304      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
305      - fix calculation of layer non-weighted velocity and layer probability
306      - add diagnostics for pot.density used for layer averaging
307    o pkg/seaice:
308      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
309        positiveness, modify a few comments and improve variable names,
310      - the changed computation of deltaC affects most seaice-related
311        experiments at the truncation level.
312        seaice_itd.thermo is affected by far the most, with
313        only 7 digits of agreement remaining; update experiments.
314    
315    checkpoint65l (2015/05/04)
316    o pkg/shelfice:
317      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
318        factor drKp1 to zero where it is negative (ie. do not use
319        SHELFICEBoundaryLayer if hFacC>1)
320      - the same for factor drLoc in shelfice_forcing.F
321    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
322        with modules in ptracers, when using testreport option "-small_f"
323    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
324      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
325    o verification/testreport
326      - add new option -small_f
327        with this option testreport first makes the target small_f (*.f files)
328        before running make (all). This is useful for explicit inlining when
329        all sources need to be full available.
330    o pkg/exf/exf_interp.F:
331        remove previous changes related to reverse (decreasing) input grids latitude
332    
333    checkpoint65k (2015/04/01)
334    o pkg/ecco:
335        fix missing cosphi initialization; use eccoiter in place of optimcycle;
336        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
337        instead of active read/write
338    o pkg/ctrl:
339        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
340        instead of active read/write.
341    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
342        return if .NOT.useAUTODIFF
343    o pkg/seaice: add CPP brackets (cost function related).
344    o model/src:
345        add useAUTODIFF run time switch.
346    o pkg/exf/exf_interp.F:
347        add code to allow input grids with latitude starting in the north (i.e. when
348        j=1 corresponds to northern edge of field); modify global_with_exf to test
349        this feature.
350    o verification/testreport:
351      - replace "grep -A3" with POSIX conformal sed command, because there are
352        implementations of grep that cannot do contextual searches
353      - replace "cat -n" by "nl" (two occurrences), because not all implementations
354        of "cat" have the option "-n"
355    o model/src:
356        add new file gsw_teos10.F that contains 3 functions, more or less a copy
357        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
358        convert from conservative to potential temperature. For now they are not
359        called anywhere.
360    o pkg/ggl90: make "useIDEMIX" useful
361      - re-organize code in s/r ggl90_calc a little to move computations that
362        are different for idemix into separate loops (changes verification
363        experiment idemix at truncation level, 12 digits remain -> updated)
364      - requires 2 new 2D fields KappaM, verticalShear
365      - make hFacI and recip_hFacI local 3D variables that are passed to
366        s/r ggl90_idemix
367      - fix and improve some comments
368    
369    checkpoint65j (2015/02/25)
370    o pkg/openad
371      - synchronize seawater.F with version in model/src: replace routine
372        body of sw_temp by calling sw_ptmp and fix/add a few comments.
373    o pkg/mnc:
374      - change default value of pickup_read/write_mnc params to FALSE
375        (since few features are missing in reading MNC pickup files).
376    o model/src:
377      - change default (background) vertical diffusivity for salt to be the
378        temperature (background) vertical diffusivity.
379      - change background vertical diffusivity in vertical mixing pkgs ggl90,
380        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
381        This makes ptracers default diffusivity (that uses salt diffKr) more
382        consistent with vertical mixing schemes.
383    o verification/testreport:
384      - fix typo in "-pcls" option ;
385      - put temp files in /tmp (instead of in local dir)
386      - add option "-ncad" to use genmake2 new option "-nocat4ad"
387      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
388    o pkg/ggl90 (idemix code):
389      - apply few fixes ; add some missing "_d 0" ; update output of exp.
390        global_ocean.90x40x15.idemix
391    o OpenAD
392      - enable active file I/O and begin removal of work-around code
393        for OpenAD for handling control variables (memory vs. active files)
394      - new CPP options file OPENAD_OPTIONS.h
395      - revert to genarr2d gradient check for hs94.1x64x5
396      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
397      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
398    o tools/genmake2:
399      - add option for an alternative Makefile (from Martin) where multiple
400        source files are sent to TAF (instead of all in one file).
401    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
402      - code provided by Carsten Eden as an extension of ggl90
403      - so far the code is turned on within ggl90 by setting a CPP-flag at
404        compile time; a runtime flag implementation is not yet complete
405      - tested in new verification experiment global_ocean.90x40x15.idemix
406    o verification:
407      - reduce length of the AD test run by half for experiments
408        global_ocean.cs32x15 (std + thsice) and isomip
409      - enable active file I/O for OpenAD, adjust verifications accordingly
410      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
411    o verification/testreport:
412      - fix two non-POSIX sed statements so that there are no error messages
413        on Mac OS X
414      - replace hostname -s with hostname | sed 's/\..*$//'
415    o model/src/seawater.F:
416      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
417        (following the matlab code), which would have avoided the bug caught
418        by Matt (see below) in the first place
419    o pkg/shelfice:
420      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
421        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
422      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
423        ice-shelf case (i.e., within surface level).
424      - add config summary in shelfice_check.F
425      - remove global variable recip_SHELFICElatentHeat and replace by a local
426        variable recip_latentHeat
427      - introduce diagnostics for friction velocity uStar (in case of
428        SHELFICEuseGammaFrict)
429      - change verification experiment isomip.htd:
430        + start from pickup (as input_ad at nIter0=8640)
431        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
432        + test SHELFICEuseGammaFrict = .TRUE.
433        + test SHELFICEadvDiffHeatFlux = .TRUE.
434    o model/src:
435      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
436        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
437        update output of experiments global_with_exf.yearly and isomip (all 6).
438    o pkg/shelfice:
439      - change setting of kTopC to also be zero where there is no ice-shelf.
440      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
441        ice-shelf is.
442      - first attempt to get RealFreshWaterFlux effects: for now, only without
443        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
444    o pkg/seaice: add the option to prescribe a fixed thickness PDF
445      for thermodynamic calculations
446      - because of divisions of the type 7/7 not exactly equal to 1, this change
447        affects results of some verification experiments by up to 4 digits:
448        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
449        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
450        adjoint: lab_sea, lab_sea.noseaicedyn
451        -> updated
452    
453    checkpoint65i (2015/01/23)
454    o model/src:
455      - change units of frictionHeating field from W to W/m^2
456      - fix bug in frictional heating from stratospheric drag in
457        S/R ATM_PHYS_TENDENCY_APPLY_V
458      - with synchronous time-stepping: move resetting to zero of frictionHeating
459        field from load_fields_driver.F to thermodynamics.F ;
460      - add diagnostics for frictional heating.
461    o model/src & gmredi K3D:
462      - add frictionHeating field to pickup-files (for synchronous time-stepping)
463      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
464      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
465        and name in pickup file).
466      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
467    o model/src:
468      - move (from ini_forcing.F) initialisation of all arrays in header file
469        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
470        (since Nov 2012) with option selectAddFluid=1.
471    o pkg/shelfice:
472      - change units (+ document) of newly added field "shelfIceMassDynTendency"
473      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
474    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
475    o pkg/seaice: two new runtime parameters:
476      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
477        long overdue
478      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
479        parameterization of tensil stress for fast ice (does not do anything yet)
480    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
481        for LSR: move checking overlaps out of JFNK-if-block
482    o pkg/atm_phys:
483      - move copy of grid and dynamical fields out of atm_phys_driver.F into
484        new S/R ATM_PHYS_DYN2PHYS.
485      - fix level height for Linear Free-Surf case (to be consistent with
486        fixed-in-time pressure levels).
487    o pkg/mom_common (bottomdrag):
488      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
489        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
490        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
491    o pkg/shelfice (u/v_drag):
492      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
493      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
494        (now similar to shelfice_u_drag.F)
495      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
496        from mom_vecinv.F (similar to mom_fluxform calls).
497    o pkg/mom_common (bottomdrag):
498      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
499      - add options for alternative discretisation of velocity norm in quadratic
500        bottom drag: averaging of grid-cell-center KE to U.point and V.point
501        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
502        improves when averaging only the other component (e.g. vVel for U bottom
503        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
504      - add options (bottomVisc_pCell) to account for partial-cell in bottom
505        friction (no-slip BC) thus getting the true distance from the bottom;
506        off by default since this also reduces model stability (explicit bottom
507        friction). Changes produce different machine truncation with linear-drag
508        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
509        front_relax (bvp & mxl, 10 & 11 digits).
510    o model/src & mom pkgs:
511      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
512        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
513      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
514        just copy level Nr value to level Nr+1.
515    o doc:
516      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
517    o pkg/streamice:
518      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
519        SHELFICE.h: move array shelficemass to init_varia, initialise
520        from array shelficemassinit, which is set in init_fixed and
521        has option to be set from file; introduce array
522        shelficeMassDynTend array, set thru file in init_fixed
523      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
524        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
525        pkg/streamice
526      - shelfice_thermodynamics.F: call shelfice_step_icemass if
527        SHELFICEMassStepping = .true.
528      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
529    
530    checkpoint65h (2014/12/17)
531    o verification/global_ocean.90x40x15, global_ocean_ebm:
532      - update to generic controls.
533    o pkg/ctrl:
534      - ctrl_map_ini_genarr.F: test for igen>0
535      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
536      - move gentim2d part of ctrl_map_ini_genarr.F to
537        new separate routine : ctrl_map_ini_gentim2d.F
538      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
539        add time variable weights and cyclic controls (time mean,
540        seasonal cycle, etc) capabilities to gentim2d
541    o pkg/ecco:
542      - move reading of error, conversion to weights from
543        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
544    o global_oce_llc90, cs32:
545      - activte sbo.
546      - CTRL_SIZE.h : add maxCtrlProc.
547      - activate the new genctrl capabilities.
548      - update following reorganization of global_oce_input_fields.tar.gz  
549    o pkg/ctrl/ctrl_ad_diff.list:
550      - add missing ctrl_init_rec.f
551    o tools/OAD_support/keepOriginal:
552      - add ctrl_init_rec.F
553    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
554      - avoid recomputations of xx_gentim2d_dummy.
555    o momentum diagnostics:
556      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
557        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
558    o pkg/seaice/seaice_lsr.F:
559      - fix computation of BU/BV, make sure they are non-zero, only necessary
560        for cubed sphere exchanges and SEAICE_OLx/y>0.
561        This makes calling s/r fill_cs_corner_rl obsolete (removed).
562    o verification/global_ocean.cs32x15/input.seaice
563      - add test for strong implicit coupling and restricted addtive Schwarz
564        methods for LSR
565      - update results/output.seaice.txt
566    o verification/tutorial_global_oce_biogeo:
567      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
568        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
569        update output_adm,_oadm,_tlm.txt
570    o pkg/dic:
571      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
572      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
573        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
574    o verification/tutorial_global_oce_biogeo:
575      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
576        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
577        update output_adm,_oadm,_tlm.txt
578    o eesupp/src:
579      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
580        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
581    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
582      LSR (following Hutchings et al. 2004)
583      - introduce zetaZ as a global variable (requires adjustments in
584        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
585        in seaice_calc_viscosities.F
586      - new flag SEAICEuseStrImpCpl (default off)
587      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
588        momentum equations
589      - JFNK-solver (preconditioner) adjusted to allow using this method
590        (where it does not have any positive effect)
591    o pkg/seaice
592      - add overlap for restrictive additive Schwartz method also to LSR, but
593        turn it off by default (because it only seems to work for non-cubed
594        sphere/llc topologies)
595    o pkg/autodiff
596      - add extra exchanges in addummy_in_steppging also for mnc output
597    o pkg/seaice:
598      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
599        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
600    o pkg/obcs:
601      - add option to specify domain-connected piece Id along OB though files
602        (for now, only used to diagnose PhiVel; default =1 -> global correction)
603      - modify obcs_diag_balance.F to process each connected-part separately;
604        exclude OB where Id = 0 but keep the full divergence there (-> constant
605        Psi along this portion of OB and all inflow derived from grad(Phi))
606      - add example of OB-conect files in verification/so_box_biogeo/input.
607    o pkg/diagnostics:
608      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
609      a) use non zero matrix element across OB and solve for Phi 1 grid point
610         outside OB (i.e, where tracer OBCS are applied).
611      b) global imbalance of inFlow/outFlow across OB: instead of modifying
612         velocity across OB, spread it uniformly along the OB in the RHS.
613    
614    checkpoint65g (2014/11/19)
615    o pkg/diagnostcis:
616      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
617    o pkg/my82,pp81,kl10:
618      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
619        field diffKr as background diffusivity to set minimum diffusivity value.
620    o pkg/seaice:
621      - add new parameter SEAICEuseEVPrev (for revisited EVP by
622        Bouillon et al 2013)
623      - add SEAICE_evpAlpha/Beta to namelist
624      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
625        involve trivial re-ordering of divisions/multiplications that should not
626        have any effects, but ... they do change the results of lab_sea.hb87 so
627        that only 2 digits of agreement remain, in line with the general
628        instability/fragility of the evp-code. For now, I do not care and just
629        update the verification experiment
630    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
631      - remove xx_genarr2d_numsmooth etc
632      - use xx_genarr2d_preproc etc instead
633      - carry out smooth_correl2D at initialization stage rather than during
634        time stepping.
635      - get smoothOpNb from xx_gentim2d_preproc
636    o global_oce_cs32 :
637      - add test of generic ecco capabilities.
638    o pkg/exf/exf_getsurfacefluxes.F :
639      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
640    o pkg/ctrl,ecco :
641      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
642        is defined.
643    o pkg/seaice: add diagnostics for Delta (deformation parameter)
644    o model/src:
645      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
646        diffusivity (background) is specified but ignored.
647    o verification:
648      - in testreport, convert hostname to lower case for default output dir name
649    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
650    o pkg/dic: add modifications from Hajoon:
651      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
652      - light attenuation: add self-shading effect by climatological Chlorophyll
653        (read from file).
654    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
655        compiles when SEAICE_ALLOW_DYNAMICS is undefined
656    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
657        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
658        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
659        approach where CPP_OPTIONS.h includes an omnipotent
660        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
661    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
662        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
663    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
664        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
665        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
666    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
667      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
668      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
669      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
670      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
671    o pkg/ctrl,ecco,exf :
672      - remove variables associated with NON-generic costs,
673        unless ECCO_CTRL_DEPRECATED is defined.
674      - remove NON-generic NON-obcs controls,
675        unless ECCO_CTRL_DEPRECATED is defined.
676    o pkg/ctrl : added ctrl_local_params.h
677    o pkg/ecco : added ecco_local_params.h
678    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
679        experiments, which will progressively be removed once the
680        experiments are revised to use only generic controls/costs.
681    
682    checkpoint65f (2014/10/13)
683    o pkg/ctrl, ecco, seaice : minor changes in headers
684    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
685        cost function and control capabilities added since checkpoint65c.
686    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
687    o pkg/ecco: increase modularity and improve logic
688      - ecco_toolbox.F (new) : basic operations that are often used,
689        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
690        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
691      - cost_gencal.F (new) : determine filnames and records.
692      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.

695      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
696      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
697        using_ers, using_gfo, using_mdt is now only defined within gencost)
698    o pkg/ecco: extend generic cost capabilities
699      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
700        capabilities via gencost_preproc (+ _c,_i,_r related params),
701        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
702        gencost_outputlevel arguments to cost_generic
703      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
704        and active_read, making room for gencost_preproc to take effect.
705        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
706      - pkg/ecco/cost_generic.F :
707        compute and store misfit maks*(model-data) in localdif that is
708        then used in cost and for output, output misfit if outlev.GT.0
709      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
710        rather gencost_barfile for deciding whether to write barfile
711      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
712      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
713        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
714      - pkg/ecco/ecco_summary.F : report gencost variables
715      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
716    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
717    o pkg/ecco: internal re-organization
718      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
719        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
720        mv relevant variables definition from ecco_cost.h to ecco.h,
721        make sure gencost routines only include ecco.h)
722      - throughout : add missing CCP switches, rm unused variables,
723        and rm un-necessary CPP switches
724      - throughout gencost routines : replace modelstartdate with
725        gencost_startdate when needed
726      - cost_bp_read.F : use arguments, instead of common blocs
727        so that it can be used also by (new) cost_gencost_bpv4.F
728      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
729      - ecco_phys.F : compute etanFull
730      - ecco_readparms.F : rename using_topex as using_tpj, add
731        bpv4-grace to gencost list, initialize added parameters
732      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
733    
734    checkpoint65e (2014/09/28)

740        (see pkg/obcs/OBCS_OPTIONS.h for details)
741    o pkg/atm_phys:
742      - implement simple (obliquity only, assuming circular planet orbit)
743        seasonal cycle for incoming insolation ; used when run-time parameter
744        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
745    o pkg/exf, pkg/ecco, pkg/ctrl:
746      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
747      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
748      - implement gentim2d for xx_tauu, xx_tauv
749    o pkg/ctrl, pkg/ecco :
750      - fix and complement the generic controls implementation
751    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
752        pkg/shelfice/shelfice_thermodynamics.F,
753        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
754        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
755      - add weight in CTRL_GET_GEN calls
756    o pkg/ctrl :
757      - ctrl_get_gen.F : add weight as input parameter, and apply
758        it directly rather than using smooth_correl2Dw (to be retired).
759      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
760    o pkg/ctrl :
761      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,

771    
772    checkpoint65d (2014/09/15)
773    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
774      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
775        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
776    o pkg/ctrl/ctrl_map_ini_genarr.F :
777      - remove compilation failure
778      - replace hard coded example
779      - use ctrl_map_ini_gen2D, 3D
780    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :

797      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
798    o ecco/ecco_ad_diff.list :
799      - add ecco_init_varia.f
800    o ecco/ecco_init_varia.F
801      - new routine
802    o pkg/streamice:
803      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
804        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
805      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
806    o pkg/generic_advdiff:
807      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
808    o pkg/exf:
809      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
810         xxg_precip capability
811      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
812    o pkg/ctrl:
813      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
814    o model/src/load_fields_driver.F :
815      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
816        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
817    o OpenAD verification experiments:
818      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
819        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
820        for now, only in pkgs used in OpenAD verification experiments.
821      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
822        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
823        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
824        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
825    o OpenAD verification tests:
826      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
827      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
828        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
829      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
830        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
831    o model/src & generic_advdiff:
832      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
833        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
834        dynamics requires valid tracer forcing only over tile interior but, for
835        some diagnostics, may need to extend it over 1 point in tile halo region.
836      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
837        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
838        setting in temp/salt/ptracer_integrate.F
839    o pkg/dic:
840      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
841        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
842        in gchem_forcing_sep.F
843    o pkg/autodiff & obcs:
844      - add storage of current OB values for U & V (was already done for T & S).
845    
846    checkpoint65c (2014/08/30)
847    o pkg/dic:
848      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
849        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
850        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
851    o verification:
852      - new experiment testing OBCS and DIC pkgs, using params & output from
853        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
854        passage: take OBCS from the last year of a 2 yrs simulation and initial
855        conditions from t=1.yr while keeping the same forcing.
856    o model/src:
857      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
858        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
859    o pkg/diagnostics (Stats-Diags):
860      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
861        a) refine region where stats are computed, excluding where arrhFac=0 ;
862        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
863        c) extend regional stats over the region edges (for U or V pt location).
864    o pkg/gchem:
865      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
866        pkg/dic is currently changing/updating ptracers values beyond the OB).
867    o verification (hs94):
868      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
869        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
870        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
871        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
872    o pkg/ptracers:
873      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
874        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
875      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
876        with AB-2 code (so that it get tested).
877    o model/src:
878      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
879        with AB-2 code (previously only available with AB-3 code).
880        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
881        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
882        there, by calling CYCLE_AB_TRACER).
883    o pkg/generic_advdiff:
884      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
885        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
886        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
887        S/R temp/salt/ptracers_integrate.F
888    o model/src & pkg/ptracers:
889      - remove common block variables gT,gS (in DYNVARS.h), except when
890         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
891      - remove common block variable gPtr.
892    o model/src & pkgs:
893      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
894         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
895         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
896         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
897      + change accordingly all calling S/R.
898      - use local temperature/salinity/ptracer tendency array (without bi,bj)
899        in S/R temp/salt/ptracers_integrate.F
900    o pkg/seaice:
901      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
902        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
903      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
904        in seaice_lsr
905      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
906        in s/r seaice_lsr_calc_coeffs
907    o pkg/mdsio:
908      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
909        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
910        too long (e.g., > MAX_LEN_FNAM/2 )
911    
912    checkpoint65b (2014/08/12)
913    o pkg/matrix:
914      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
915    o model/src:
916      - fix initialisation of geothermalFile; compile geothermal-flux code in
917        natl_box verification experiment.
918    o model/src & pkg/down_slope:
919      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
920      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
921        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
922        results at machine truncation level: update output of experiments
923        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
924    o pkg/diagnostics (Stats-Diags):
925      - do not cumulate the full volume when DIAGNOSTICS_FILL is
926        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
927        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
928        times (but Min,Max and StD are still wrong).
929    o model/src:
930      - add geothermal flux forcing: read in ini_forcing.F as time-constant
931        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
932    o model/src:
933      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
934        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
935        arrays are already updated while adjustments (filters, conv.adjustment) are
936        still applied later, in S/R TRACERS_CORRECTION_STEP.
