5      ==============================      ==============================
6    
7    o pkg/atm_ocn_coupler + ocn_compon_interf:
8      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
9        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
10        add corresponding call in DO_OCEANIC_PHYS.
11    o coupler pkgs:
12      Start a new way to set-up optionally-exchanged variables (previously, only
13       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
14       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
15       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
16       compononent param default can be set accordingly).
17      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
18       but rather applies to a group a fields (going both ways like for DIC)
19       and corresponds to an option of coupling config.
20      coupler (pkg/atm_ocn_coupler):
21      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
22        and read namelist directly (without eessup S/R calls) instead of
23        in the very un-flexible old way, 1 param per line, in fixed order;
24      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
25        cleanly in CPL_CHECK_CPLCONFIG
26      - add new coupling-exchange selectors (some not yet active) including
27        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
28                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
29      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
30        component ; called directly from coupler.F, after comp. registrations;
31      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
32         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
33          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
34      components (pkg/atm_ & ocn_compon_interf):
35      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
36        CPP header file in all pkg source files.
37      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
38        ATM/OCN_CHECK_CPLCONFIG;
39      - add error-counter to track errors (e.g., in "data.cpl") and to stop
40        cleanly in ATM/OCN_CHECK_CPLCONFIG;
41      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
42        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
43        before PACKAGES_READPARMS;
44      verification/cpl_aim+ocn/:
45      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
46        "data.cpl" for coupler (in input_cpl).
47    o eesupp/inc:
48      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
49        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
50        to always cumulate tile local-sum in the same order (still uses
51        MPI_Allreduce like standard code).
52      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
53        that are now identical to standard version (in eesupp/inc).
54    o pkg/shelfice:
55      - add SHELFICETransCoeffTFile for initializing spatially varying
56        heat and salt transfer coefficients
57    o pkg/atm_compon_interf & ocn_compon_interf:
58      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
59        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
60      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
61    o pkg/atm_ocn_coupler:
62      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
63    o pkg/rbcs:
64      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
65        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
66      - add a short report (to STDOUT) about RBCS-mask settings.
67    
68    checkpoint65p (2015/10/23)
69    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
70        there is no adjoint test for EVP, we don't know what it does to the adjoint
71        solution, but at least there are no more recomputation warnings left
72    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
73        a chance of giving the same results as a fully converged VP (JFNK) solver
74    o tools/adjoint_options/adjoint_diva:
75      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
76    o pkg/streamice:
77      - spotted bug in streamice_driving_stress using dyG where should have been dxG
78    o pkg/exf:
79      - remove STOP statement that prevented to use wind or (wind-)stress
80        interpolation for constant-in-time forcing fields (wind/stress period = 0).
81    o pkg/seaice:
82      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
83        5 additionals 2D fields and 6 new store directives
84      - change logic in seaice_readparms.F: EVP code can now be turned on in
85        various ways, setting SEAICE_deltaTev is no longer required,
86        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
87        or SEAICEaEVPcoeff
88    o pkg/shelfice/shelfice_thermodynamics.F
89      - redefining uLoc/vLoc to u/v, instead of 2u/v
90    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
91      - this is an intermediate state of a truely converging EVP that has
92        the potential of outperforming implicit VP methods, I do not recommend
93        using it yet.
94      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
95        and all parameters are hardwired
96      - for convergence it still requires very smooth regularisations, that means,
97        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
98        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
99        specific averaging appears to be required, still subject to tuning
100      - still needs cleaning and I need to turn parameter into runtime parameters
101      - add code to compute and print residuals of iteration, compile with
102        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
103    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
104      that entered with r1.54 on Sep04, 2015, -> update results
105    
106    checkpoint65o (2015/09/14)
107    o pkg/mom_vecinv & mom_common:
108      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
109        called from there.
110      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
111        allows to use Vector-Invariant form in deep atmos and anelastic formulation
112    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
113      and Koenig-Beatty+Holland (2012)
114      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
115      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
116      - requires an extra input argument for S/R seaice_calc_viscosities
117      - tensileStrength's depth dependence is different from Itkin et al. (2015)
118        (to be changed and played with, for now exponential)
119    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
120      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
121        by AREA according to Connelly et al. (2004), JPO.
122      - For EVP and the LSR solver, the implicit part of the drag term is
123        the only non-zero term in the denominator when there is no ice (which
124        prevented running the model with zero ice-ocean drag). If
125        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
126        (or zero main diagonals BU/BV) which need to be caught. A practical
127        consequence is that for open water, the momentum equation reduce
128        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
129        they happen to be zero, often leading to a non-zero solution over
130        open water.
131    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
132        efficient EVP method.
133      - introduce area-weighted averages for e12 (analogously to
134        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
135        remain, but also changing the order of terms in the previous average
136        changed the results as much) -> update experiment
137      - add SEAICE_DELTA_SMOOTHREG code
138      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
139        TEM-code
140      - adjust loop bounds so that only required fields are computed
141      - add new averaging code for zetaZ/deltaZ (again similar to
142        seaice_calc_viscosities.F), inactive by default for now (will change
143        results again), but will replace old code eventually
144    o eesupp/src:
145      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
146        to always cumulate tile local-sum in the same order
147        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
148        Still uses MPI_Allreduce (like standard code) but on array of tiles
149        and should be faster than GLOBAL_SUM_SEND_RECV code.
150      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
151        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
152      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
153         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
154         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
155         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
156         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
157    
158    checkpoint65n (2015/07/29)
159    o pkg/thsice:
160      - add a warning when used with pkg/aim but without updating SST
161        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
162    o pkg/offline:
163      - change where Offline-Fields are loaded, from load_fields_driver.F to
164        directly within FORWARD_STEP, just after updating iter number and time;
165      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
166        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
167       These changes allow:
168        a) to recover exactly on-line results using deltaToffline=deltaTClock,
169        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
170        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
171        time-step, both with GM & KPP files and with recomputing these fields;
172        b) no needs to switch on staggerTimeStep anymore;
173        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
174      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
175    o pkg/offline:
176      - change (rarely used) offset-iteration parameter to an offset time (in s):
177        can easily recover previous offset-iter effect by setting offset-time
178        (offlineTimeOffset) to offset-iter x deltaToffline;
179      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
180        in KPP as part of surface buoyancy forcing) in offline run.
181      - fix ptracers KPP non-local term in the case where KPP is re-computed.
182    o OpenAD
183      - Adding preliminary ggl90 test to OpenAD verification.
184        Config. with ggl90 currently diverges after 64 time steps
185        so will need more work to become more stable
186      - Adding preliminary kpp test to OpenAD verification.
187        required small tweakes in kpp_routines.F
188      - Merge and update from Krishna Narayanan's contrib area:
189        * Add one variable for preliminary OpenAD DIVA
190        * Add replacement time-stepping for OpenAD DIVA
191        * genmake2 flag -diva (but only for OpenAD; preliminary)
192        * required modifs for OAD_support
193        successful preliminary test for tutorial_global_oce_biogeo/
194    o pkg/seaice:
195      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
196      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
197        delta with a smooth function in s/r seaice_calc_viscosity
198        (no effect on EVP)
199      - rename local suffix "sqr" into "sq" for more consistent variable names
200    o pkg/seaice:
201        add new parameter SEAICE_deltaMin that is used ***only***
202        for regularizing Delta (and nothing else, like the parameter
203        which is also used for all sorts of things SEAICE_EPS).
204        Defaults to SEAICE_EPS for backward compatibility only.
205    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
206        the wrong key by inialising it before use -> fixes a recomputation
207        problem but does not fix the gradient
208    o pkg/layers:
209      - move resetting of flux arrays to outside the iLa loop
210        (this caused layers_diapycnal to not work with more than one layer coord.)
211      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
212    o pkg/layers:
213      - remove from common block 3D layers fields (used to diagnose transport
214        in tracer coords) and declare them as local arrays in layers_calc.F
215    o pkg/seaice:
216      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
217        in lab_sea forward experiment (changes results -> updated)
218      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
219    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
220       computations; for SEAICE_VECTORIZE_LSR
221      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
222        sweep to the outside,
223      - remove store directives and add "CADJ loop sequential" directives
224        in analogy to model/src/solve_tridiagonal.F
225      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
226        boundaries to yield more readable code. This has also the charming side
227        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
228        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
229        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
230        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
231        an additional option)
232       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
233       but the adjoint gradients (which are affected by this change) still explode.
234    o coupler (atm & ocn _compon_interf):
235      - avoid using Exch2 IO mapping if not suitable.
236    
237    checkpoint65m (2015/06/15)
238    o pkg/layers:
239      - clean-up old parameters setting (from Sep 2012):
240        + remove old parameters setting from common block (declared locally);
241        + stop if any old parameter is mixed with new parameters;
242        + check for valid or consistent parameter setting (e.g., layers_name)
243      - check that layers_bounds for Pot.Density are in the right range;
244        this is supposed to catch un-updated setting after recently shifting
245        potential density field "prho" by -1000 (now in "sigma" scale).
246    o pkg/layers:
247      - Added missing call to layers_fill for keeping track of tottend in
248        pkg/diagnostics/diagnostics_fill_state.F
249    o pkg/layers:
250      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
251        of diapycnal fluxes
252    o pkg/layers:
253      - reverted changes to interpolation to previous treatment; there
254        was never actually a problem
255    o pkg/layers:
256      - fix interpolation of layers tracers in the presence of partial cells
257      - add lots of new functionality to compute water mass transformation
258        (enabled by CPP flag LAYERS_THERMODYNAMICS)
259      - add new calls from main code (diags_oceanic_surf_flux.F,
260        thermodynamics.F, impldiff.F) and gad to save the necessary fields
261        for layers_thermodynamics calculations
262    o pkg/ptracers:
263      - add capability of stepping a passive tracer forward without advection
264        by setting PTRACERS_advScheme to 0.
265    o pkg/diagnostics:
266      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
267    o pkg/layers:
268      - shift potential density field "prho" by -1000 for density layer averaging so
269        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
270        Note that density bin boundaries (layers_bounds in data.layers) have
271        to be set accordingly (i.e., shifted, in sigma scale).
272    o pkg/layers:
273      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
274      - fix calculation of layer non-weighted velocity and layer probability
275      - add diagnostics for pot.density used for layer averaging
276    o pkg/seaice:
277      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
278        positiveness, modify a few comments and improve variable names,
279      - the changed computation of deltaC affects most seaice-related
280        experiments at the truncation level.
281        seaice_itd.thermo is affected by far the most, with
282        only 7 digits of agreement remaining; update experiments.
283    
284    checkpoint65l (2015/05/04)
285    o pkg/shelfice:
286      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
287        factor drKp1 to zero where it is negative (ie. do not use
288        SHELFICEBoundaryLayer if hFacC>1)
289      - the same for factor drLoc in shelfice_forcing.F
290    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
291        with modules in ptracers, when using testreport option "-small_f"
292    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
293      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
294    o verification/testreport
295      - add new option -small_f
296        with this option testreport first makes the target small_f (*.f files)
297        before running make (all). This is useful for explicit inlining when
298        all sources need to be full available.
299    o pkg/exf/exf_interp.F:
300        remove previous changes related to reverse (decreasing) input grids latitude
301    
302    checkpoint65k (2015/04/01)
303    o pkg/ecco:
304        fix missing cosphi initialization; use eccoiter in place of optimcycle;
305        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
306        instead of active read/write
307    o pkg/ctrl:
308        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
309        instead of active read/write.
310    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
311        return if .NOT.useAUTODIFF
312    o pkg/seaice: add CPP brackets (cost function related).
313    o model/src:
314        add useAUTODIFF run time switch.
315    o pkg/exf/exf_interp.F:
316        add code to allow input grids with latitude starting in the north (i.e. when
317        j=1 corresponds to northern edge of field); modify global_with_exf to test
318        this feature.
319    o verification/testreport:
320      - replace "grep -A3" with POSIX conformal sed command, because there are
321        implementations of grep that cannot do contextual searches
322      - replace "cat -n" by "nl" (two occurrences), because not all implementations
323        of "cat" have the option "-n"
324    o model/src:
325        add new file gsw_teos10.F that contains 3 functions, more or less a copy
326        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
327        convert from conservative to potential temperature. For now they are not
328        called anywhere.
329    o pkg/ggl90: make "useIDEMIX" useful
330      - re-organize code in s/r ggl90_calc a little to move computations that
331        are different for idemix into separate loops (changes verification
332        experiment idemix at truncation level, 12 digits remain -> updated)
333      - requires 2 new 2D fields KappaM, verticalShear
334      - make hFacI and recip_hFacI local 3D variables that are passed to
335        s/r ggl90_idemix
336      - fix and improve some comments
337    
338    checkpoint65j (2015/02/25)
339    o pkg/openad
340      - synchronize seawater.F with version in model/src: replace routine
341        body of sw_temp by calling sw_ptmp and fix/add a few comments.
342    o pkg/mnc:
343      - change default value of pickup_read/write_mnc params to FALSE
344        (since few features are missing in reading MNC pickup files).
345    o model/src:
346      - change default (background) vertical diffusivity for salt to be the
347        temperature (background) vertical diffusivity.
348      - change background vertical diffusivity in vertical mixing pkgs ggl90,
349        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
350        This makes ptracers default diffusivity (that uses salt diffKr) more
351        consistent with vertical mixing schemes.
352    o verification/testreport:
353      - fix typo in "-pcls" option ;
354      - put temp files in /tmp (instead of in local dir)
355      - add option "-ncad" to use genmake2 new option "-nocat4ad"
356      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
357    o pkg/ggl90 (idemix code):
358      - apply few fixes ; add some missing "_d 0" ; update output of exp.
359        global_ocean.90x40x15.idemix
360    o OpenAD
361      - enable active file I/O and begin removal of work-around code
362        for OpenAD for handling control variables (memory vs. active files)
363      - new CPP options file OPENAD_OPTIONS.h
364      - revert to genarr2d gradient check for hs94.1x64x5
365      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
366      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
367    o tools/genmake2:
368      - add option for an alternative Makefile (from Martin) where multiple
369        source files are sent to TAF (instead of all in one file).
370    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
371      - code provided by Carsten Eden as an extension of ggl90
372      - so far the code is turned on within ggl90 by setting a CPP-flag at
373        compile time; a runtime flag implementation is not yet complete
374      - tested in new verification experiment global_ocean.90x40x15.idemix
375    o verification:
376      - reduce length of the AD test run by half for experiments
377        global_ocean.cs32x15 (std + thsice) and isomip
378      - enable active file I/O for OpenAD, adjust verifications accordingly
379      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
380    o verification/testreport:
381      - fix two non-POSIX sed statements so that there are no error messages
382        on Mac OS X
383      - replace hostname -s with hostname | sed 's/\..*$//'
384    o model/src/seawater.F:
385      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
386        (following the matlab code), which would have avoided the bug caught
387        by Matt (see below) in the first place
388    o pkg/shelfice:
389      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
390        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
391      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
392        ice-shelf case (i.e., within surface level).
393      - add config summary in shelfice_check.F
394      - remove global variable recip_SHELFICElatentHeat and replace by a local
395        variable recip_latentHeat
396      - introduce diagnostics for friction velocity uStar (in case of
397        SHELFICEuseGammaFrict)
398      - change verification experiment isomip.htd:
399        + start from pickup (as input_ad at nIter0=8640)
400        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
401        + test SHELFICEuseGammaFrict = .TRUE.
402        + test SHELFICEadvDiffHeatFlux = .TRUE.
403    o model/src:
404      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
405        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
406        update output of experiments global_with_exf.yearly and isomip (all 6).
407    o pkg/shelfice:
408      - change setting of kTopC to also be zero where there is no ice-shelf.
409      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
410        ice-shelf is.
411      - first attempt to get RealFreshWaterFlux effects: for now, only without
412        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
413    o pkg/seaice: add the option to prescribe a fixed thickness PDF
414      for thermodynamic calculations
415      - because of divisions of the type 7/7 not exactly equal to 1, this change
416        affects results of some verification experiments by up to 4 digits:
417        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
418        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
419        adjoint: lab_sea, lab_sea.noseaicedyn
420        -> updated
421    
422    checkpoint65i (2015/01/23)
423    o model/src:
424      - change units of frictionHeating field from W to W/m^2
425      - fix bug in frictional heating from stratospheric drag in
426        S/R ATM_PHYS_TENDENCY_APPLY_V
427      - with synchronous time-stepping: move resetting to zero of frictionHeating
428        field from load_fields_driver.F to thermodynamics.F ;
429      - add diagnostics for frictional heating.
430    o model/src & gmredi K3D:
431      - add frictionHeating field to pickup-files (for synchronous time-stepping)
432      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
433      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
434        and name in pickup file).
435      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
436    o model/src:
437      - move (from ini_forcing.F) initialisation of all arrays in header file
438        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
439        (since Nov 2012) with option selectAddFluid=1.
440    o pkg/shelfice:
441      - change units (+ document) of newly added field "shelfIceMassDynTendency"
442      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
443    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
444    o pkg/seaice: two new runtime parameters:
445      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
446        long overdue
447      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
448        parameterization of tensil stress for fast ice (does not do anything yet)
449    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
450        for LSR: move checking overlaps out of JFNK-if-block
451    o pkg/atm_phys:
452      - move copy of grid and dynamical fields out of atm_phys_driver.F into
453        new S/R ATM_PHYS_DYN2PHYS.
454      - fix level height for Linear Free-Surf case (to be consistent with
455        fixed-in-time pressure levels).
456    o pkg/mom_common (bottomdrag):
457      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
458        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
459        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
460    o pkg/shelfice (u/v_drag):
461      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
462      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
463        (now similar to shelfice_u_drag.F)
464      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
465        from mom_vecinv.F (similar to mom_fluxform calls).
466    o pkg/mom_common (bottomdrag):
467      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
468      - add options for alternative discretisation of velocity norm in quadratic
469        bottom drag: averaging of grid-cell-center KE to U.point and V.point
470        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
471        improves when averaging only the other component (e.g. vVel for U bottom
472        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
473      - add options (bottomVisc_pCell) to account for partial-cell in bottom
474        friction (no-slip BC) thus getting the true distance from the bottom;
475        off by default since this also reduces model stability (explicit bottom
476        friction). Changes produce different machine truncation with linear-drag
477        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
478        front_relax (bvp & mxl, 10 & 11 digits).
479    o model/src & mom pkgs:
480      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
481        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
482      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
483        just copy level Nr value to level Nr+1.
484    o doc:
485      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
486    o pkg/streamice:
487      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
488        SHELFICE.h: move array shelficemass to init_varia, initialise
489        from array shelficemassinit, which is set in init_fixed and
490        has option to be set from file; introduce array
491        shelficeMassDynTend array, set thru file in init_fixed
492      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
493        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
494        pkg/streamice
495      - shelfice_thermodynamics.F: call shelfice_step_icemass if
496        SHELFICEMassStepping = .true.
497      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
498    
499    checkpoint65h (2014/12/17)
500    o verification/global_ocean.90x40x15, global_ocean_ebm:
501      - update to generic controls.
502    o pkg/ctrl:
503      - ctrl_map_ini_genarr.F: test for igen>0
504      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
505      - move gentim2d part of ctrl_map_ini_genarr.F to
506        new separate routine : ctrl_map_ini_gentim2d.F
507      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
508        add time variable weights and cyclic controls (time mean,
509        seasonal cycle, etc) capabilities to gentim2d
510    o pkg/ecco:
511      - move reading of error, conversion to weights from
512        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
513    o global_oce_llc90, cs32:
514      - activte sbo.
515      - CTRL_SIZE.h : add maxCtrlProc.
516      - activate the new genctrl capabilities.
517      - update following reorganization of global_oce_input_fields.tar.gz  
518    o pkg/ctrl/ctrl_ad_diff.list:
519      - add missing ctrl_init_rec.f
520    o tools/OAD_support/keepOriginal:
521      - add ctrl_init_rec.F
522    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
523      - avoid recomputations of xx_gentim2d_dummy.
524    o momentum diagnostics:
525      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
526        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
527    o pkg/seaice/seaice_lsr.F:
528      - fix computation of BU/BV, make sure they are non-zero, only necessary
529        for cubed sphere exchanges and SEAICE_OLx/y>0.
530        This makes calling s/r fill_cs_corner_rl obsolete (removed).
531    o verification/global_ocean.cs32x15/input.seaice
532      - add test for strong implicit coupling and restricted addtive Schwarz
533        methods for LSR
534      - update results/output.seaice.txt
535    o verification/tutorial_global_oce_biogeo:
536      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
537        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
538        update output_adm,_oadm,_tlm.txt
539    o pkg/dic:
540      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
541      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
542        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
543    o verification/tutorial_global_oce_biogeo:
544      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
545        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
546        update output_adm,_oadm,_tlm.txt
547    o eesupp/src:
548      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
549        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
550    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
551      LSR (following Hutchings et al. 2004)
552      - introduce zetaZ as a global variable (requires adjustments in
553        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
554        in seaice_calc_viscosities.F
555      - new flag SEAICEuseStrImpCpl (default off)
556      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
557        momentum equations
558      - JFNK-solver (preconditioner) adjusted to allow using this method
559        (where it does not have any positive effect)
560    o pkg/seaice
561      - add overlap for restrictive additive Schwartz method also to LSR, but
562        turn it off by default (because it only seems to work for non-cubed
563        sphere/llc topologies)
564    o pkg/autodiff
565      - add extra exchanges in addummy_in_steppging also for mnc output
566    o pkg/seaice:
567      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
568        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
569    o pkg/obcs:
570      - add option to specify domain-connected piece Id along OB though files
571        (for now, only used to diagnose PhiVel; default =1 -> global correction)
572      - modify obcs_diag_balance.F to process each connected-part separately;
573        exclude OB where Id = 0 but keep the full divergence there (-> constant
574        Psi along this portion of OB and all inflow derived from grad(Phi))
575      - add example of OB-conect files in verification/so_box_biogeo/input.
576    o pkg/diagnostics:
577      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
578      a) use non zero matrix element across OB and solve for Phi 1 grid point
579         outside OB (i.e, where tracer OBCS are applied).
580      b) global imbalance of inFlow/outFlow across OB: instead of modifying
581         velocity across OB, spread it uniformly along the OB in the RHS.
582    
583    checkpoint65g (2014/11/19)
584    o pkg/diagnostcis:
585      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
586    o pkg/my82,pp81,kl10:
587      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
588        field diffKr as background diffusivity to set minimum diffusivity value.
589    o pkg/seaice:
590      - add new parameter SEAICEuseEVPrev (for revisited EVP by
591        Bouillon et al 2013)
592      - add SEAICE_evpAlpha/Beta to namelist
593      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
594        involve trivial re-ordering of divisions/multiplications that should not
595        have any effects, but ... they do change the results of lab_sea.hb87 so
596        that only 2 digits of agreement remain, in line with the general
597        instability/fragility of the evp-code. For now, I do not care and just
598        update the verification experiment
599    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
600      - remove xx_genarr2d_numsmooth etc
601      - use xx_genarr2d_preproc etc instead
602      - carry out smooth_correl2D at initialization stage rather than during
603        time stepping.
604      - get smoothOpNb from xx_gentim2d_preproc
605    o global_oce_cs32 :
606      - add test of generic ecco capabilities.
607    o pkg/exf/exf_getsurfacefluxes.F :
608      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
609    o pkg/ctrl,ecco :
610      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
611        is defined.
612    o pkg/seaice: add diagnostics for Delta (deformation parameter)
613    o model/src:
614      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
615        diffusivity (background) is specified but ignored.
616    o verification:
617      - in testreport, convert hostname to lower case for default output dir name
618    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
619    o pkg/dic: add modifications from Hajoon:
620      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
621      - light attenuation: add self-shading effect by climatological Chlorophyll
622        (read from file).
623    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
624        compiles when SEAICE_ALLOW_DYNAMICS is undefined
625    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
626        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
627        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
628        approach where CPP_OPTIONS.h includes an omnipotent
629        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
630    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
631        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
632    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
633        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
634        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
635    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
636      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
637      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
638      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
639      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
640    o pkg/ctrl,ecco,exf :
641      - remove variables associated with NON-generic costs,
642        unless ECCO_CTRL_DEPRECATED is defined.
643      - remove NON-generic NON-obcs controls,
644        unless ECCO_CTRL_DEPRECATED is defined.
645    o pkg/ctrl : added ctrl_local_params.h
646    o pkg/ecco : added ecco_local_params.h
647    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
648        experiments, which will progressively be removed once the
649        experiments are revised to use only generic controls/costs.
650    
651    checkpoint65f (2014/10/13)
652    o pkg/ctrl, ecco, seaice : minor changes in headers
653    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
654        cost function and control capabilities added since checkpoint65c.
655    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
656    o pkg/ecco: increase modularity and improve logic
657      - ecco_toolbox.F (new) : basic operations that are often used,
658        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
659        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
660      - cost_gencal.F (new) : determine filnames and records.
661      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
662      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
663        and exploit the above functions leading to more compact code.
664      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
665      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
666        using_ers, using_gfo, using_mdt is now only defined within gencost)
667    o pkg/ecco: extend generic cost capabilities
668      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
669        capabilities via gencost_preproc (+ _c,_i,_r related params),
670        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
671        gencost_outputlevel arguments to cost_generic
672      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
673        and active_read, making room for gencost_preproc to take effect.
674        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
675      - pkg/ecco/cost_generic.F :
676        compute and store misfit maks*(model-data) in localdif that is
677        then used in cost and for output, output misfit if outlev.GT.0
678      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
679        rather gencost_barfile for deciding whether to write barfile
680      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
681      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
682        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
683      - pkg/ecco/ecco_summary.F : report gencost variables
684      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
685    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
686    o pkg/ecco: internal re-organization
687      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
688        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
689        mv relevant variables definition from ecco_cost.h to ecco.h,
690        make sure gencost routines only include ecco.h)
691      - throughout : add missing CCP switches, rm unused variables,
692        and rm un-necessary CPP switches
693      - throughout gencost routines : replace modelstartdate with
694        gencost_startdate when needed
695      - cost_bp_read.F : use arguments, instead of common blocs
696        so that it can be used also by (new) cost_gencost_bpv4.F
697      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
698      - ecco_phys.F : compute etanFull
699      - ecco_readparms.F : rename using_topex as using_tpj, add
700        bpv4-grace to gencost list, initialize added parameters
701      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
702    
703    checkpoint65e (2014/09/28)
704    o pkg/obcs:
705      - replaced the just-added CPP options with run-time variables
706        (see pkg/obcs/OBCS_PARAMS.h for details)
707    o pkg/obcs:
708      - add additional CPP options for sponge boundary layers
709        (see pkg/obcs/OBCS_OPTIONS.h for details)
710    o pkg/atm_phys:
711      - implement simple (obliquity only, assuming circular planet orbit)
712        seasonal cycle for incoming insolation ; used when run-time parameter
713        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
714    o pkg/exf, pkg/ecco, pkg/ctrl:
715      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
716      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
717      - implement gentim2d for xx_tauu, xx_tauv
718    o pkg/ctrl, pkg/ecco :
719      - fix and complement the generic controls implementation
720    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
721        pkg/shelfice/shelfice_thermodynamics.F,
722        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
723        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
724      - add weight in CTRL_GET_GEN calls
725    o pkg/ctrl :
726      - ctrl_get_gen.F : add weight as input parameter, and apply
727        it directly rather than using smooth_correl2Dw (to be retired).
728      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
729    o pkg/ctrl :
730      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
731        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
732      - re-activate ctrl_summary (call in ctrl_init.F)
733    o pkg/ctrl/ctrl_cost_gen.F :
734      - fix CCP brackets, remove un-necessary myiter, mytime
735    o pkg/ecco, pkg/ctrl :
736      - remove cost_genctrl.F (now pkg/ctrl/ctrl_cost_driver.F)
737      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
738      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
739      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
740    
741    checkpoint65d (2014/09/15)
742    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
743      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
744        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
745    o pkg/ctrl/ctrl_map_ini_genarr.F :
746      - remove compilation failure
747      - replace hard coded example
748      - use ctrl_map_ini_gen2D, 3D
749    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
750      - on/off switch based upon xx_genarr2d_weight,3d
751    o src/packages_init_variables.F :
752      - regroup pkg/estimation calls
753      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
754        (moved to ctrl_init_variables)
755    o cost/cost_init_varia.F :
756      - remove ecco_cost_init_varia
757        (moved to ecco_init_varia)
758    o ctrl/ctrl_init_variables.F :
759      - add CTRL_MAP_INI, CTRL_MAP_INI_ECCO
760      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
761    o ctrl/ctrl_map_ini.F :
762      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
763        (moved to ctrl_init_variables)
764    o ctrl/ctrl_map_ini_ecco.F :
765      - remove ECCO_PHYS (mv to ecco_init_varia)
766      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
767    o ecco/ecco_ad_diff.list :
768      - add ecco_init_varia.f
769    o ecco/ecco_init_varia.F
770      - new routine
771    o pkg/streamice:
772      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
773        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
774      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
775    o pkg/generic_advdiff:
776      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
777    o pkg/exf:
778      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
779         xxg_precip capability
780      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
781    o pkg/ctrl:
782      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
783    o model/src/load_fields_driver.F :
784      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
785        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
786    o OpenAD verification experiments:
787      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
788        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
789        for now, only in pkgs used in OpenAD verification experiments.
790      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
791        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
792        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
793        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
794    o OpenAD verification tests:
795      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
796      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
797        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
798      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
799        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
800    o model/src & generic_advdiff:
801      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
802        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
803        dynamics requires valid tracer forcing only over tile interior but, for
804        some diagnostics, may need to extend it over 1 point in tile halo region.
805      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
806        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
807        setting in temp/salt/ptracer_integrate.F
808    o pkg/dic:
809      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
810        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
811        in gchem_forcing_sep.F
812    o pkg/autodiff & obcs:
813      - add storage of current OB values for U & V (was already done for T & S).
814    
815    checkpoint65c (2014/08/30)
816    o pkg/dic:
817      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
818        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
819        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
820    o verification:
821      - new experiment testing OBCS and DIC pkgs, using params & output from
822        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
823        passage: take OBCS from the last year of a 2 yrs simulation and initial
824        conditions from t=1.yr while keeping the same forcing.
825    o model/src:
826      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
827        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
828    o pkg/diagnostics (Stats-Diags):
829      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
830        a) refine region where stats are computed, excluding where arrhFac=0 ;
831        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
832        c) extend regional stats over the region edges (for U or V pt location).
833    o pkg/gchem:
834      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
835        pkg/dic is currently changing/updating ptracers values beyond the OB).
836    o verification (hs94):
837      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
838        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
839        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
840        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
841    o pkg/ptracers:
842      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
843        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
844      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
845        with AB-2 code (so that it get tested).
846    o model/src:
847      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
848        with AB-2 code (previously only available with AB-3 code).
849        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
850        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
851        there, by calling CYCLE_AB_TRACER).
852    o pkg/generic_advdiff:
853      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
854        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
855        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
856        S/R temp/salt/ptracers_integrate.F
857    o model/src & pkg/ptracers:
858      - remove common block variables gT,gS (in DYNVARS.h), except when
859         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
860      - remove common block variable gPtr.
861    o model/src & pkgs:
862      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
863         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
864         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
865         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
866      + change accordingly all calling S/R.
867      - use local temperature/salinity/ptracer tendency array (without bi,bj)
868        in S/R temp/salt/ptracers_integrate.F
869    o pkg/seaice:
870      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
871        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
872      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
873        in seaice_lsr
874      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
875        in s/r seaice_lsr_calc_coeffs
876    o pkg/mdsio:
877      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
878        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
879        too long (e.g., > MAX_LEN_FNAM/2 )
880    
881    checkpoint65b (2014/08/12)
882    o pkg/matrix:
883      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
884    o model/src:
885      - fix initialisation of geothermalFile; compile geothermal-flux code in
886        natl_box verification experiment.
887    o model/src & pkg/down_slope:
888      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
889      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
890        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
891        results at machine truncation level: update output of experiments
892        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
893    o pkg/diagnostics (Stats-Diags):
894      - do not cumulate the full volume when DIAGNOSTICS_FILL is
895        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
896        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
897        times (but Min,Max and StD are still wrong).
898    o model/src:
899      - add geothermal flux forcing: read in ini_forcing.F as time-constant
900        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
901    o model/src:
902      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
903        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
904        arrays are already updated while adjustments (filters, conv.adjustment) are
905        still applied later, in S/R TRACERS_CORRECTION_STEP.
906    o model/src:
907      - store in common bloc array "rhoInSitu" the virtual potential temperature
908        anomaly that is used to compute geopotential: this make the atmos code
909        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
910    o pkg/seaice/seaice_lsr.F
911      - rename integer variable ilcall to ipass (that's what it is called
912        in the residual diagnostics
913      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
914        default) for improved non-linear convergence of the first few steps
915      - adjust a few comments and add new ones to explain some of the store
916        directives
917    o pkg/generic_advdiff (& ptracers):
918      - re-work the code to check for valid advection scheme and for minimum
919        size of overlap (now stored in local common bloc in gad_advscheme.F)
920    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
921      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
922      - add an auxilliary variable "bet" and fix store directives and keys in
923        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
924        less exact gradients in my tests); but there are still
925        recomputation warning (although gradients are sort of OK), when
926        SEAICE_LSR_VECTORIZE is not defined, so this flag and
927        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
928      - update verification experiments lab_sea.
929      - change some comments in S/R seaice_calc_viscosities
930    o model/src:
931      - if staggerTimeStep=T, always apply exchange to velocity field in
932        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
933        (independent of using multi-dim advection or not); no effect on FWD run
934        but affects AD results (at machine truncation level): update output of
935        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
936        and isomip (oad: 12.d).
937    o pkg/generic_advdiff:
938      - stop if doAB_onGtGs is set to FALSE but ignored
939      - refine warning related to stability of tracer time-stepping
940        regarding internal wave dynamics.
941      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
942        on staggerTimeStep & implicitIntGravWave (will now get a warning
943        if potentially unstable).
944    o pkg/kl10:
945      - add new pkg "kl10" for mixing due to internal wave breaking, from
946        http://www.sciencedirect.com/science/article/pii/S1463500310000144
947        (contribution from Jody Klymak), tested in verification experiment
948        verification/internal_wave/input.kl10/
949    o isomip experiment:
950      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
951        (input.htd) and update the output.
952    o cd_code experiments:
953      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
954        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
955        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
956        update the corresponding output.
957    o pkg/seaice:
958      - reduce the number of include files and store directives in
959        S/R seaice_lsr_tridiagu/v
960      - change the order of loops in one case in S/R seaice_lsr_tridiagv
961        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
962        get rid off one store directive (a TAF bug?)
963      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
964        S/R seaice_lsr_tridiagv to change the loop range for consistency
965      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
966      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
967        S/R seaice_lsr_tridiagu/v (requires update of
968        offline_exf_seaice/input.dyn_jfnk)
969    
970    checkpoint65a (2014/07/27)
971    o model/src:
972      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
973        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
974        (topo in p-coords, ice-shelf in z-coords); update output of experiments
975        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
976    o model/src:
977      - collect momentum forcing tendency into local 2-D array (passed as argument
978        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
979        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
980        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
981      - collect T & S forcing tendency into local 2-D array (passed as argument to
982        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
983        affects results at machine truncation level (e.g., ocean: if using
984        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
985        correction due to vertical advection).
986      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
987        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
988        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
989        obcs_ctrl (ad & fwd grd @ 12 & 7).
990    o pkg/ptracers & diagnostics:
991      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
992        title (to avoid some unexpected truncation); sort out ptracers diags units.
993      - collect ptracer forcing tendency into local 2-D array (passed as argument
994        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
995    
996    checkpoint65 (2014/07/18)
997    o pkg/fizhi:
998      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
999        affects results at machine truncation level. Update output of experiments
1000        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1001    o pkg/seaice: more clean up
1002      - rename TAF common block tapes to be more consistent and remove
1003        unnecessary duplicates
1004      - add store directives to remove more recomputations, but use smaller
1005        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1006        The idea behind this flag is to reduce the memory footprint when the
1007        adjoint of the LSR is not required. As of now, defining the flag
1008        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1009        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1010        For experiment offline_exf_seaice, this means on a linux box with gfortran
1011        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1012        this experiment):
1013        > size mitgcmuv_ad
1014        text    data        bss     dec        hex
1015        5100659 1216  220458952  225560827  d71c8fb
1016        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1017        but only a moderate increase of 36% for global_ocean.cs32x15:
1018        text    data        bss     dec        hex
1019        6695027 1648 1014578664 1021275339 3cdf6ccb
1020        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1021      - note: there are still recomputations in global_ocean.cs32x15 and
1022        offline_exf_seaice and the gradient agreement changes (gets a
1023        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1024      - in general, the AD gradients still are wrong
1025    o OpenAD
1026      - clean up code_oad/ directories somewhat by moving files
1027        dontCompile, dontTransform, keepOriginal to OAD_support/
1028    o model/src:
1029      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1030        (not currently tested): add dissipation terms before NLFS rescaling of
1031        tendencies (previously done after).
1032    o pkg/diagnostics:
1033      - write stats-diags in ascii file with more digits (same as in monitor).
1034    o pkg/down_slope:
1035      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1036        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1037    o model/src:
1038      - new file "apply_forcing.F" containing all the code previously in
1039        external_forcing.F, but with new argument list: pass, as new argument,
1040        the current level tendency array to update (instead of a direct update
1041        of the common bloc array). Change the corresponding calls.
1042      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1043        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1044    o pkg/seaice/seaice_lsr, a little bit of clean up
1045      - rearrange some code blocks, so that now all calculations for
1046        setting up the right-hand-sides done within one single block
1047        (I find that easier to read and understand)
1048      - rearrange freedrift-code to reduce the number of ifdefs
1049      - adjust some indentations and comments
1050    
1051    checkpoint64z (2014/07/10)
1052    o model/src and several pkgs:
1053      - change argument list of all S/R called from external_forcing.F and
1054        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1055        to pass, as argument, the current level tendency array to update
1056        (instead of a direct update of the common bloc array).
1057      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1058      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1059    o pkg/seaice/seaice_lsr.F
1060      - always initialize local arrays in seaice_lsr_tridiagu/v
1061      - add more local tapes to seaice_lsr_tridiagu/v
1062      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1063        keep it in bi/bj loop; this seems to be essential
1064      - gradients are still wrong but only by 4-7 orders of magnitude
1065        instead of 15 orders of magnitude, lab_sea improves a little
1066    o pkg/seaice
1067      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1068        generates unnecessary code in seaice_lsr_ad
1069      - add more store directives in seaice_lsr to avoid unnecessary code
1070        in seaice_lsr_ad
1071      - exclude some residual computations in seaice_lsr when
1072        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1073        in seaice_lsr_ad
1074      - add more storing, a new tape (model/src/the_main_loop.F) and
1075        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1076        and klockey should be checked by a specialist)
1077      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1078        and update lab_sea after previous changes in pkg/seaice below
1079    o pkg/autodiff:
1080      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1081        viscFacInAd : run time parameters allowing for adjoint switches
1082        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1083    o pkg/ecco:
1084      - introduce cost_gencost_boxmean.F that computes a box mean
1085        temperature (for use in adjoint sensitivity studies).
1086    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1087    o pkg/mom_common/mom_calc_visc.F:
1088      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1089    o pkg/seaice/seaice_summary.F:
1090      - statement for SEAICEadjMODE now in autodiff_readparms.F
1091    o pkg/seaice:
1092      - remove some store directives and add new ones in an effort to get
1093        finally rid off the recomputation warnings. This is successful
1094        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1095        defined (i.e. no extensive recomputation warnings left), but there
1096        are still too many recomputations on the solver iteration level
1097      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1098      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1099        SEAICE_SIZE.h
1100      - add a store directive in S/R seaice_calc_viscosities
1101    o pkg/seaice (ITD code):
1102      - fix definition of Hlimit for multi-threaded case
1103      - use double precision arithmetic to compute Hlimit: this affects results;
1104        update output of experiment seaice_itd.
1105    o replace content of verification/seaice_itd
1106      - instead of a 1D column use the configuration of offline_exf_seaice
1107        to test the ice thickness distribution code with ridging
1108      - this is a first shot at this experiment
1109      - change of some defaults of ridging parameters SEAICEhStar (from
1110        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1111        and lot of new comments.
1112    
1113    checkpoint64y (2014/06/20)
1114    o pkg/seaice/seaice_reg_ridge.F:
1115      - modify the regularization of very small volumes of ice; only check
1116        total volume HEFF, and do not apply correction to individual ice
1117        classes because that leads to funny patterns in the heat and fw-fluxes
1118        into the ocean. Adjust seaice_itd/results/output.txt
1119      - replace nITD by SEAICE_multDim in loop-ranges
1120    o pkg/exf:
1121      - add code to process the case field period = -12. with UV interpolation.
1122      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1123        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1124    o verification/global_with_exf:
1125      - switch all fields period to -12. (was previously untested) in input/data.exf
1126        (but keep secondary test ".yearly" unchanged); update the reference output.
1127    o pkg/cal:
1128      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1129    o pkg/exf:
1130      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1131        to replace logical switch "exf_verbose"
1132      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1133    o pkg/sbo:
1134      - update from Katherine Quinn: evaluate mass directly from density and SSH
1135        (budget using Finite Volume method) instead of from bottom pressure.
1136      - allow testreport to collect few selected SBO output ; tested in exp.
1137        global_ocean.90x40x15 (after updating the results, to include SBO output).
1138      - fix some multi-threading issues (in output part).
1139  o model/src & most packages:  o model/src & most packages:
1140    - always call {PKG}_READPARMS even if corresponding use{PKG}=F;    - always call {PKG}_READPARMS even if corresponding use{PKG}=F;

1146  o pkg/seaice:  o pkg/seaice:
1147    - remove code that resets useThSice in S/R seaice_readparms and    - remove code that resets useThSice in S/R seaice_readparms and
