# Line 5  $Name$ Line 5  $Name$
5      ==============================      ==============================
6    
7  o pkg/diagnostics:  o pkg/diagnostics:
8      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
9    o pkg/layers:
10      - shift potential density field "prho" by -1000 for density layer averaging so
11        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
12        Note that density bin boundaries (layers_bounds in data.layers) have
13        to be set accordingly (i.e., shifted, in sigma scale).
14    o pkg/layers:
15      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
16      - fix calculation of layer non-weighted velocity and layer probability
17      - add diagnostics for pot.density used for layer averaging
18    o pkg/seaice:
19      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
20        positiveness, modify a few comments and improve variable names,
21      - the changed computation of deltaC affects most seaice-related
22        experiments at the truncation level.
23        seaice_itd.thermo is affected by far the most, with
24        only 7 digits of agreement remaining; update experiments.
25    
26    checkpoint65l (2015/05/04)
27    o pkg/shelfice:
28      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
29        factor drKp1 to zero where it is negative (ie. do not use
30        SHELFICEBoundaryLayer if hFacC>1)
31      - the same for factor drLoc in shelfice_forcing.F
32    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
33        with modules in ptracers, when using testreport option "-small_f"
34    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
35      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
36    o verification/testreport
37      - add new option -small_f
38        with this option testreport first makes the target small_f (*.f files)
39        before running make (all). This is useful for explicit inlining when
40        all sources need to be full available.
41    o pkg/exf/exf_interp.F:
42        remove previous changes related to reverse (decreasing) input grids latitude
43    
44    checkpoint65k (2015/04/01)
45    o pkg/ecco:
46        fix missing cosphi initialization; use eccoiter in place of optimcycle;
47        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
48        instead of active read/write
49    o pkg/ctrl:
50        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
51        instead of active read/write.
52    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
53        return if .NOT.useAUTODIFF
54    o pkg/seaice: add CPP brackets (cost function related).
55    o model/src:
56        add useAUTODIFF run time switch.
57    o pkg/exf/exf_interp.F:
58        add code to allow input grids with latitude starting in the north (i.e. when
59        j=1 corresponds to northern edge of field); modify global_with_exf to test
60        this feature.
61    o verification/testreport:
62      - replace "grep -A3" with POSIX conformal sed command, because there are
63        implementations of grep that cannot do contextual searches
64      - replace "cat -n" by "nl" (two occurrences), because not all implementations
65        of "cat" have the option "-n"
66    o model/src:
67        add new file gsw_teos10.F that contains 3 functions, more or less a copy
68        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
69        convert from conservative to potential temperature. For now they are not
70        called anywhere.
71    o pkg/ggl90: make "useIDEMIX" useful
72      - re-organize code in s/r ggl90_calc a little to move computations that
73        are different for idemix into separate loops (changes verification
74        experiment idemix at truncation level, 12 digits remain -> updated)
75      - requires 2 new 2D fields KappaM, verticalShear
76      - make hFacI and recip_hFacI local 3D variables that are passed to
77        s/r ggl90_idemix
78      - fix and improve some comments
79    
80    checkpoint65j (2015/02/25)
81    o pkg/openad
82      - synchronize seawater.F with version in model/src: replace routine
83        body of sw_temp by calling sw_ptmp and fix/add a few comments.
84    o pkg/mnc:
85      - change default value of pickup_read/write_mnc params to FALSE
86        (since few features are missing in reading MNC pickup files).
87    o model/src:
88      - change default (background) vertical diffusivity for salt to be the
89        temperature (background) vertical diffusivity.
90      - change background vertical diffusivity in vertical mixing pkgs ggl90,
91        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
92        This makes ptracers default diffusivity (that uses salt diffKr) more
93        consistent with vertical mixing schemes.
94    o verification/testreport:
95      - fix typo in "-pcls" option ;
96      - put temp files in /tmp (instead of in local dir)
97      - add option "-ncad" to use genmake2 new option "-nocat4ad"
98      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
99    o pkg/ggl90 (idemix code):
100      - apply few fixes ; add some missing "_d 0" ; update output of exp.
101        global_ocean.90x40x15.idemix
102    o OpenAD
103      - enable active file I/O and begin removal of work-around code
104        for OpenAD for handling control variables (memory vs. active files)
105      - new CPP options file OPENAD_OPTIONS.h
106      - revert to genarr2d gradient check for hs94.1x64x5
107      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
108      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
109    o tools/genmake2:
110      - add option for an alternative Makefile (from Martin) where multiple
111        source files are sent to TAF (instead of all in one file).
112    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
113      - code provided by Carsten Eden as an extension of ggl90
114      - so far the code is turned on within ggl90 by setting a CPP-flag at
115        compile time; a runtime flag implementation is not yet complete
116      - tested in new verification experiment global_ocean.90x40x15.idemix
117    o verification:
118      - reduce length of the AD test run by half for experiments
119        global_ocean.cs32x15 (std + thsice) and isomip
120      - enable active file I/O for OpenAD, adjust verifications accordingly
121      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
122    o verification/testreport:
123      - fix two non-POSIX sed statements so that there are no error messages
124        on Mac OS X
125      - replace hostname -s with hostname | sed 's/\..*$//'
126    o model/src/seawater.F:
127      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
128        (following the matlab code), which would have avoided the bug caught
129        by Matt (see below) in the first place
130    o pkg/shelfice:
131      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
132        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
133      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
134        ice-shelf case (i.e., within surface level).
135      - add config summary in shelfice_check.F
136      - remove global variable recip_SHELFICElatentHeat and replace by a local
137        variable recip_latentHeat
138      - introduce diagnostics for friction velocity uStar (in case of
139        SHELFICEuseGammaFrict)
140      - change verification experiment isomip.htd:
141        + start from pickup (as input_ad at nIter0=8640)
142        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
143        + test SHELFICEuseGammaFrict = .TRUE.
144        + test SHELFICEadvDiffHeatFlux = .TRUE.
145    o model/src:
146      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
147        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
148        update output of experiments global_with_exf.yearly and isomip (all 6).
149    o pkg/shelfice:
150      - change setting of kTopC to also be zero where there is no ice-shelf.
151      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
152        ice-shelf is.
153      - first attempt to get RealFreshWaterFlux effects: for now, only without
154        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
155    o pkg/seaice: add the option to prescribe a fixed thickness PDF
156      for thermodynamic calculations
157      - because of divisions of the type 7/7 not exactly equal to 1, this change
158        affects results of some verification experiments by up to 4 digits:
159        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
160        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
161        adjoint: lab_sea, lab_sea.noseaicedyn
162        -> updated
163    
164    checkpoint65i (2015/01/23)
165    o model/src:
166      - change units of frictionHeating field from W to W/m^2
167      - fix bug in frictional heating from stratospheric drag in
168        S/R ATM_PHYS_TENDENCY_APPLY_V
169      - with synchronous time-stepping: move resetting to zero of frictionHeating
170        field from load_fields_driver.F to thermodynamics.F ;
171      - add diagnostics for frictional heating.
172    o model/src & gmredi K3D:
173      - add frictionHeating field to pickup-files (for synchronous time-stepping)
174      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
175      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
176        and name in pickup file).
177      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
178    o model/src:
179      - move (from ini_forcing.F) initialisation of all arrays in header file
180        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
181        (since Nov 2012) with option selectAddFluid=1.
182    o pkg/shelfice:
183      - change units (+ document) of newly added field "shelfIceMassDynTendency"
184      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
185    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
186    o pkg/seaice: two new runtime parameters:
187      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
188        long overdue
189      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
190        parameterization of tensil stress for fast ice (does not do anything yet)
191    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
192        for LSR: move checking overlaps out of JFNK-if-block
193    o pkg/atm_phys:
194      - move copy of grid and dynamical fields out of atm_phys_driver.F into
195        new S/R ATM_PHYS_DYN2PHYS.
196      - fix level height for Linear Free-Surf case (to be consistent with
197        fixed-in-time pressure levels).
198    o pkg/mom_common (bottomdrag):
199      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
200        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
201        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
202    o pkg/shelfice (u/v_drag):
203      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
204      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
205        (now similar to shelfice_u_drag.F)
206      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
207        from mom_vecinv.F (similar to mom_fluxform calls).
208    o pkg/mom_common (bottomdrag):
209      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
210      - add options for alternative discretisation of velocity norm in quadratic
211        bottom drag: averaging of grid-cell-center KE to U.point and V.point
212        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
213        improves when averaging only the other component (e.g. vVel for U bottom
214        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
215      - add options (bottomVisc_pCell) to account for partial-cell in bottom
216        friction (no-slip BC) thus getting the true distance from the bottom;
217        off by default since this also reduces model stability (explicit bottom
218        friction). Changes produce different machine truncation with linear-drag
219        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
220        front_relax (bvp & mxl, 10 & 11 digits).
221    o model/src & mom pkgs:
222      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
223        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
224      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
225        just copy level Nr value to level Nr+1.
226    o doc:
227      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
228    o pkg/streamice:
229      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
230        SHELFICE.h: move array shelficemass to init_varia, initialise
231        from array shelficemassinit, which is set in init_fixed and
232        has option to be set from file; introduce array
233        shelficeMassDynTend array, set thru file in init_fixed
234      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
235        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
236        pkg/streamice
237      - shelfice_thermodynamics.F: call shelfice_step_icemass if
238        SHELFICEMassStepping = .true.
239      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
240    
241    checkpoint65h (2014/12/17)
242    o verification/global_ocean.90x40x15, global_ocean_ebm:
243      - update to generic controls.
244    o pkg/ctrl:
245      - ctrl_map_ini_genarr.F: test for igen>0
246      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
247      - move gentim2d part of ctrl_map_ini_genarr.F to
248        new separate routine : ctrl_map_ini_gentim2d.F
249      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
250        add time variable weights and cyclic controls (time mean,
251        seasonal cycle, etc) capabilities to gentim2d
252    o pkg/ecco:
253      - move reading of error, conversion to weights from
254        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
255    o global_oce_llc90, cs32:
256      - activte sbo.
257      - CTRL_SIZE.h : add maxCtrlProc.
258      - activate the new genctrl capabilities.
259      - update following reorganization of global_oce_input_fields.tar.gz  
260    o pkg/ctrl/ctrl_ad_diff.list:
261      - add missing ctrl_init_rec.f
262    o tools/OAD_support/keepOriginal:
263      - add ctrl_init_rec.F
264    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
265      - avoid recomputations of xx_gentim2d_dummy.
266    o momentum diagnostics:
267      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
268        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
269    o pkg/seaice/seaice_lsr.F:
270      - fix computation of BU/BV, make sure they are non-zero, only necessary
271        for cubed sphere exchanges and SEAICE_OLx/y>0.
272        This makes calling s/r fill_cs_corner_rl obsolete (removed).
273    o verification/global_ocean.cs32x15/input.seaice
274      - add test for strong implicit coupling and restricted addtive Schwarz
275        methods for LSR
276      - update results/output.seaice.txt
277    o verification/tutorial_global_oce_biogeo:
278      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
279        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
280        update output_adm,_oadm,_tlm.txt
281    o pkg/dic:
282      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
283      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
284        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
285    o verification/tutorial_global_oce_biogeo:
286      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
287        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
288        update output_adm,_oadm,_tlm.txt
289    o eesupp/src:
290      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
291        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
292    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
293      LSR (following Hutchings et al. 2004)
294      - introduce zetaZ as a global variable (requires adjustments in
295        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
296        in seaice_calc_viscosities.F
297      - new flag SEAICEuseStrImpCpl (default off)
298      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
299        momentum equations
300      - JFNK-solver (preconditioner) adjusted to allow using this method
301        (where it does not have any positive effect)
302    o pkg/seaice
303      - add overlap for restrictive additive Schwartz method also to LSR, but
304        turn it off by default (because it only seems to work for non-cubed
305        sphere/llc topologies)
306    o pkg/autodiff
307      - add extra exchanges in addummy_in_steppging also for mnc output
308    o pkg/seaice:
309      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
310        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
311    o pkg/obcs:
312      - add option to specify domain-connected piece Id along OB though files
313        (for now, only used to diagnose PhiVel; default =1 -> global correction)
314      - modify obcs_diag_balance.F to process each connected-part separately;
315        exclude OB where Id = 0 but keep the full divergence there (-> constant
316        Psi along this portion of OB and all inflow derived from grad(Phi))
317      - add example of OB-conect files in verification/so_box_biogeo/input.
318    o pkg/diagnostics:
319      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
320      a) use non zero matrix element across OB and solve for Phi 1 grid point
321         outside OB (i.e, where tracer OBCS are applied).
322      b) global imbalance of inFlow/outFlow across OB: instead of modifying
323         velocity across OB, spread it uniformly along the OB in the RHS.
324    
325    checkpoint65g (2014/11/19)
326    o pkg/diagnostcis:
327      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
328    o pkg/my82,pp81,kl10:
329      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
330        field diffKr as background diffusivity to set minimum diffusivity value.
331    o pkg/seaice:
332      - add new parameter SEAICEuseEVPrev (for revisited EVP by
333        Bouillon et al 2013)
334      - add SEAICE_evpAlpha/Beta to namelist
335      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
336        involve trivial re-ordering of divisions/multiplications that should not
337        have any effects, but ... they do change the results of lab_sea.hb87 so
338        that only 2 digits of agreement remain, in line with the general
339        instability/fragility of the evp-code. For now, I do not care and just
340        update the verification experiment
341    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
342      - remove xx_genarr2d_numsmooth etc
343      - use xx_genarr2d_preproc etc instead
344      - carry out smooth_correl2D at initialization stage rather than during
345        time stepping.
346      - get smoothOpNb from xx_gentim2d_preproc
347    o global_oce_cs32 :
348      - add test of generic ecco capabilities.
349    o pkg/exf/exf_getsurfacefluxes.F :
350      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
351    o pkg/ctrl,ecco :
352      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
353        is defined.
354    o pkg/seaice: add diagnostics for Delta (deformation parameter)
355    o model/src:
356      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
357        diffusivity (background) is specified but ignored.
358    o verification:
359      - in testreport, convert hostname to lower case for default output dir name
360    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
361    o pkg/dic: add modifications from Hajoon:
362      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
363      - light attenuation: add self-shading effect by climatological Chlorophyll
364        (read from file).
365    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
366        compiles when SEAICE_ALLOW_DYNAMICS is undefined
367    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
368        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
369        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
370        approach where CPP_OPTIONS.h includes an omnipotent
371        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
372    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
373        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
374    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
375        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
376        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
377    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
378      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
379      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
380      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
381      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
382    o pkg/ctrl,ecco,exf :
383      - remove variables associated with NON-generic costs,
384        unless ECCO_CTRL_DEPRECATED is defined.
385      - remove NON-generic NON-obcs controls,
386        unless ECCO_CTRL_DEPRECATED is defined.
387    o pkg/ctrl : added ctrl_local_params.h
388    o pkg/ecco : added ecco_local_params.h
389    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
390        experiments, which will progressively be removed once the
391        experiments are revised to use only generic controls/costs.
392    
393    checkpoint65f (2014/10/13)
394    o pkg/ctrl, ecco, seaice : minor changes in headers
395    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
396        cost function and control capabilities added since checkpoint65c.
397    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
398    o pkg/ecco: increase modularity and improve logic
399      - ecco_toolbox.F (new) : basic operations that are often used,
400        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
401        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
402      - cost_gencal.F (new) : determine filnames and records.
403      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
404      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
405        and exploit the above functions leading to more compact code.
406      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
407      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
408        using_ers, using_gfo, using_mdt is now only defined within gencost)
409    o pkg/ecco: extend generic cost capabilities
410      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
411        capabilities via gencost_preproc (+ _c,_i,_r related params),
412        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
413        gencost_outputlevel arguments to cost_generic
414      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
415        and active_read, making room for gencost_preproc to take effect.
416        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
417      - pkg/ecco/cost_generic.F :
418        compute and store misfit maks*(model-data) in localdif that is
419        then used in cost and for output, output misfit if outlev.GT.0
420      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
421        rather gencost_barfile for deciding whether to write barfile
422      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
423      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
424        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
425      - pkg/ecco/ecco_summary.F : report gencost variables
426      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
427    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
428    o pkg/ecco: internal re-organization
429      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
430        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
431        mv relevant variables definition from ecco_cost.h to ecco.h,
432        make sure gencost routines only include ecco.h)
433      - throughout : add missing CCP switches, rm unused variables,
434        and rm un-necessary CPP switches
435      - throughout gencost routines : replace modelstartdate with
436        gencost_startdate when needed
437      - cost_bp_read.F : use arguments, instead of common blocs
438        so that it can be used also by (new) cost_gencost_bpv4.F
439      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
440      - ecco_phys.F : compute etanFull
441      - ecco_readparms.F : rename using_topex as using_tpj, add
442        bpv4-grace to gencost list, initialize added parameters
443      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
444    
445    checkpoint65e (2014/09/28)
446    o pkg/obcs:
447      - replaced the just-added CPP options with run-time variables
448        (see pkg/obcs/OBCS_PARAMS.h for details)
449    o pkg/obcs:
450      - add additional CPP options for sponge boundary layers
451        (see pkg/obcs/OBCS_OPTIONS.h for details)
452    o pkg/atm_phys:
453      - implement simple (obliquity only, assuming circular planet orbit)
454        seasonal cycle for incoming insolation ; used when run-time parameter
455        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
456    o pkg/exf, pkg/ecco, pkg/ctrl:
457      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
458      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
459      - implement gentim2d for xx_tauu, xx_tauv
460    o pkg/ctrl, pkg/ecco :
461      - fix and complement the generic controls implementation
462    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
463        pkg/shelfice/shelfice_thermodynamics.F,
464        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
465        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
466      - add weight in CTRL_GET_GEN calls
467    o pkg/ctrl :
468      - ctrl_get_gen.F : add weight as input parameter, and apply
469        it directly rather than using smooth_correl2Dw (to be retired).
470      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
471    o pkg/ctrl :
472      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
473        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
474      - re-activate ctrl_summary (call in ctrl_init.F)
475    o pkg/ctrl/ctrl_cost_gen.F :
476      - fix CCP brackets, remove un-necessary myiter, mytime
477    o pkg/ecco, pkg/ctrl :

479      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
480      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
481      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
482    
483    checkpoint65d (2014/09/15)
484    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
485      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
486        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
487    o pkg/ctrl/ctrl_map_ini_genarr.F :
488      - remove compilation failure
489      - replace hard coded example
490      - use ctrl_map_ini_gen2D, 3D
491    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
492      - on/off switch based upon xx_genarr2d_weight,3d
493    o src/packages_init_variables.F :
494      - regroup pkg/estimation calls
495      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
496        (moved to ctrl_init_variables)
497    o cost/cost_init_varia.F :
498      - remove ecco_cost_init_varia
499        (moved to ecco_init_varia)
500    o ctrl/ctrl_init_variables.F :

502      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
503    o ctrl/ctrl_map_ini.F :
504      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
505        (moved to ctrl_init_variables)
506    o ctrl/ctrl_map_ini_ecco.F :
507      - remove ECCO_PHYS (mv to ecco_init_varia)
508      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
509    o ecco/ecco_ad_diff.list :
510      - add ecco_init_varia.f
511    o ecco/ecco_init_varia.F
512      - new routine
513    o pkg/streamice:
514      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
515        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
516      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
517    o pkg/generic_advdiff:
518      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
519    o pkg/exf:
520      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
521         xxg_precip capability
522      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
523    o pkg/ctrl:
524      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
525    o model/src/load_fields_driver.F :
526      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
527        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
528    o OpenAD verification experiments:
529      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
530        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
531        for now, only in pkgs used in OpenAD verification experiments.
532      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
533        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
534        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
535        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
536    o OpenAD verification tests:
537      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
538      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
539        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
540      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
541        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
542    o model/src & generic_advdiff:
543      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
544        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
545        dynamics requires valid tracer forcing only over tile interior but, for
546        some diagnostics, may need to extend it over 1 point in tile halo region.
547      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
548        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
549        setting in temp/salt/ptracer_integrate.F
550    o pkg/dic:
551      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
552        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
553        in gchem_forcing_sep.F
554    o pkg/autodiff & obcs:
555      - add storage of current OB values for U & V (was already done for T & S).
556    
557    checkpoint65c (2014/08/30)
558    o pkg/dic:
559      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
560        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
561        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
562    o verification:
563      - new experiment testing OBCS and DIC pkgs, using params & output from
564        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
565        passage: take OBCS from the last year of a 2 yrs simulation and initial
566        conditions from t=1.yr while keeping the same forcing.
567    o model/src:
568      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
569        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
570    o pkg/diagnostics (Stats-Diags):
571      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
572        a) refine region where stats are computed, excluding where arrhFac=0 ;
573        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
574        c) extend regional stats over the region edges (for U or V pt location).
575    o pkg/gchem:
576      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
577        pkg/dic is currently changing/updating ptracers values beyond the OB).
578    o verification (hs94):
579      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
580        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
581        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
582        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
583    o pkg/ptracers:
584      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
585        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
586      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
587        with AB-2 code (so that it get tested).
588    o model/src:
589      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
590        with AB-2 code (previously only available with AB-3 code).
591        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
592        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
593        there, by calling CYCLE_AB_TRACER).
594    o pkg/generic_advdiff:
595      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
596        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
597        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
598        S/R temp/salt/ptracers_integrate.F
599    o model/src & pkg/ptracers:
600      - remove common block variables gT,gS (in DYNVARS.h), except when
601         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
602      - remove common block variable gPtr.
603    o model/src & pkgs:
604      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
605         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
606         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
607         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
608      + change accordingly all calling S/R.
609      - use local temperature/salinity/ptracer tendency array (without bi,bj)
610        in S/R temp/salt/ptracers_integrate.F
611    o pkg/seaice:
612      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
613        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
614      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
615        in seaice_lsr
616      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
617        in s/r seaice_lsr_calc_coeffs
618    o pkg/mdsio:
619      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
620        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
621        too long (e.g., > MAX_LEN_FNAM/2 )
622    
623    checkpoint65b (2014/08/12)
624    o pkg/matrix:
625      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
626    o model/src:
627      - fix initialisation of geothermalFile; compile geothermal-flux code in
628        natl_box verification experiment.
629    o model/src & pkg/down_slope:
630      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
631      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
632        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
633        results at machine truncation level: update output of experiments
634        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
635    o pkg/diagnostics (Stats-Diags):
636      - do not cumulate the full volume when DIAGNOSTICS_FILL is
637        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
638        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
639        times (but Min,Max and StD are still wrong).
640    o model/src:
641      - add geothermal flux forcing: read in ini_forcing.F as time-constant
642        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
643    o model/src:
644      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
645        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
646        arrays are already updated while adjustments (filters, conv.adjustment) are
647        still applied later, in S/R TRACERS_CORRECTION_STEP.
648    o model/src:
649      - store in common bloc array "rhoInSitu" the virtual potential temperature
650        anomaly that is used to compute geopotential: this make the atmos code
651        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
652    o pkg/seaice/seaice_lsr.F
653      - rename integer variable ilcall to ipass (that's what it is called
654        in the residual diagnostics
655      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
656        default) for improved non-linear convergence of the first few steps
657      - adjust a few comments and add new ones to explain some of the store
658        directives
659    o pkg/generic_advdiff (& ptracers):
660      - re-work the code to check for valid advection scheme and for minimum
661        size of overlap (now stored in local common bloc in gad_advscheme.F)
662    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
663      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
664      - add an auxilliary variable "bet" and fix store directives and keys in
665        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
666        less exact gradients in my tests); but there are still
667        recomputation warning (although gradients are sort of OK), when
668        SEAICE_LSR_VECTORIZE is not defined, so this flag and
669        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
670      - update verification experiments lab_sea.
671      - change some comments in S/R seaice_calc_viscosities
672    o model/src:
673      - if staggerTimeStep=T, always apply exchange to velocity field in
674        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
675        (independent of using multi-dim advection or not); no effect on FWD run
676        but affects AD results (at machine truncation level): update output of
677        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
678        and isomip (oad: 12.d).
679    o pkg/generic_advdiff:
680      - stop if doAB_onGtGs is set to FALSE but ignored
681      - refine warning related to stability of tracer time-stepping
682        regarding internal wave dynamics.
683      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
684        on staggerTimeStep & implicitIntGravWave (will now get a warning
685        if potentially unstable).
686    o pkg/kl10:
687      - add new pkg "kl10" for mixing due to internal wave breaking, from
688        http://www.sciencedirect.com/science/article/pii/S1463500310000144
689        (contribution from Jody Klymak), tested in verification experiment
690        verification/internal_wave/input.kl10/
691    o isomip experiment:
692      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
693        (input.htd) and update the output.
694    o cd_code experiments:
695      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
696        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
697        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
698        update the corresponding output.
699    o pkg/seaice:
700      - reduce the number of include files and store directives in
701        S/R seaice_lsr_tridiagu/v
702      - change the order of loops in one case in S/R seaice_lsr_tridiagv
703        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
704        get rid off one store directive (a TAF bug?)
705      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
706        S/R seaice_lsr_tridiagv to change the loop range for consistency
707      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
708      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
709        S/R seaice_lsr_tridiagu/v (requires update of
710        offline_exf_seaice/input.dyn_jfnk)
711    
712    checkpoint65a (2014/07/27)
713    o model/src:
714      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
715        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
716        (topo in p-coords, ice-shelf in z-coords); update output of experiments
717        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
718    o model/src:
719      - collect momentum forcing tendency into local 2-D array (passed as argument
720        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
721        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
722        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
723      - collect T & S forcing tendency into local 2-D array (passed as argument to
724        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
725        affects results at machine truncation level (e.g., ocean: if using
726        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
727        correction due to vertical advection).
728      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
729        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
730        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
731        obcs_ctrl (ad & fwd grd @ 12 & 7).
732    o pkg/ptracers & diagnostics:
733      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
734        title (to avoid some unexpected truncation); sort out ptracers diags units.
735      - collect ptracer forcing tendency into local 2-D array (passed as argument
736        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
737    
738    checkpoint65 (2014/07/18)
739    o pkg/fizhi:
740      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
741        affects results at machine truncation level. Update output of experiments
742        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
743    o pkg/seaice: more clean up
744      - rename TAF common block tapes to be more consistent and remove
745        unnecessary duplicates
746      - add store directives to remove more recomputations, but use smaller
747        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
748        The idea behind this flag is to reduce the memory footprint when the
749        adjoint of the LSR is not required. As of now, defining the flag
750        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
751        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
752        For experiment offline_exf_seaice, this means on a linux box with gfortran
753        nearly a factor of 10 (but keep in mind there is mostly seaice code in
754        this experiment):
755        > size mitgcmuv_ad
756        text    data        bss     dec        hex
757        5100659 1216  220458952  225560827  d71c8fb
758        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
759        but only a moderate increase of 36% for global_ocean.cs32x15:
760        text    data        bss     dec        hex
761        6695027 1648 1014578664 1021275339 3cdf6ccb
762        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
763      - note: there are still recomputations in global_ocean.cs32x15 and
764        offline_exf_seaice and the gradient agreement changes (gets a
765        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
766      - in general, the AD gradients still are wrong
767    o OpenAD
768      - clean up code_oad/ directories somewhat by moving files
769        dontCompile, dontTransform, keepOriginal to OAD_support/
770    o model/src:
771      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
772        (not currently tested): add dissipation terms before NLFS rescaling of
773        tendencies (previously done after).
774    o pkg/diagnostics:
775      - write stats-diags in ascii file with more digits (same as in monitor).
776    o pkg/down_slope:
777      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
778        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
779    o model/src:
780      - new file "apply_forcing.F" containing all the code previously in
781        external_forcing.F, but with new argument list: pass, as new argument,
782        the current level tendency array to update (instead of a direct update
783        of the common bloc array). Change the corresponding calls.
784      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
785        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
786    o pkg/seaice/seaice_lsr, a little bit of clean up
787      - rearrange some code blocks, so that now all calculations for
788        setting up the right-hand-sides done within one single block
789        (I find that easier to read and understand)
790      - rearrange freedrift-code to reduce the number of ifdefs
791      - adjust some indentations and comments
792    
793    checkpoint64z (2014/07/10)
794    o model/src and several pkgs:
795      - change argument list of all S/R called from external_forcing.F and
796        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
797        to pass, as argument, the current level tendency array to update
798        (instead of a direct update of the common bloc array).
799      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
800      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
801    o pkg/seaice/seaice_lsr.F
802      - always initialize local arrays in seaice_lsr_tridiagu/v
803      - add more local tapes to seaice_lsr_tridiagu/v
804      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
805        keep it in bi/bj loop; this seems to be essential
806      - gradients are still wrong but only by 4-7 orders of magnitude
807        instead of 15 orders of magnitude, lab_sea improves a little
808    o pkg/seaice
809      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
810        generates unnecessary code in seaice_lsr_ad
811      - add more store directives in seaice_lsr to avoid unnecessary code
812        in seaice_lsr_ad
813      - exclude some residual computations in seaice_lsr when
814        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
815        in seaice_lsr_ad
816      - add more storing, a new tape (model/src/the_main_loop.F) and
817        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
818        and klockey should be checked by a specialist)
819      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
820        and update lab_sea after previous changes in pkg/seaice below
821    o pkg/autodiff:
822      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
823        viscFacInAd : run time parameters allowing for adjoint switches
824        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
825    o pkg/ecco:
826      - introduce cost_gencost_boxmean.F that computes a box mean
827        temperature (for use in adjoint sensitivity studies).
828    o model/src/set_defaults.F : initialize viscFacAdj to 1.
829    o pkg/mom_common/mom_calc_visc.F:
830      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
831    o pkg/seaice/seaice_summary.F:
832      - statement for SEAICEadjMODE now in autodiff_readparms.F
833    o pkg/seaice:
834      - remove some store directives and add new ones in an effort to get
835        finally rid off the recomputation warnings. This is successful
836        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
837        defined (i.e. no extensive recomputation warnings left), but there
838        are still too many recomputations on the solver iteration level
839      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
840      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
841        SEAICE_SIZE.h
842      - add a store directive in S/R seaice_calc_viscosities
843    o pkg/seaice (ITD code):
844      - fix definition of Hlimit for multi-threaded case
845      - use double precision arithmetic to compute Hlimit: this affects results;
846        update output of experiment seaice_itd.
847    o replace content of verification/seaice_itd
848      - instead of a 1D column use the configuration of offline_exf_seaice
849        to test the ice thickness distribution code with ridging
850      - this is a first shot at this experiment
851      - change of some defaults of ridging parameters SEAICEhStar (from
852        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
853        and lot of new comments.
854    
855    checkpoint64y (2014/06/20)
856    o pkg/seaice/seaice_reg_ridge.F:
857      - modify the regularization of very small volumes of ice; only check
858        total volume HEFF, and do not apply correction to individual ice
859        classes because that leads to funny patterns in the heat and fw-fluxes
860        into the ocean. Adjust seaice_itd/results/output.txt
861      - replace nITD by SEAICE_multDim in loop-ranges
862    o pkg/exf:
863      - add code to process the case field period = -12. with UV interpolation.
864      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
865        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
866    o verification/global_with_exf:
867      - switch all fields period to -12. (was previously untested) in input/data.exf
868        (but keep secondary test ".yearly" unchanged); update the reference output.
869    o pkg/cal:
870      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
871    o pkg/exf:
872      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
873        to replace logical switch "exf_verbose"
874      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
875    o pkg/sbo:
876      - update from Katherine Quinn: evaluate mass directly from density and SSH
877        (budget using Finite Volume method) instead of from bottom pressure.
878      - allow testreport to collect few selected SBO output ; tested in exp.
879        global_ocean.90x40x15 (after updating the results, to include SBO output).
880      - fix some multi-threading issues (in output part).
881    o model/src & most packages:
882      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
883      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
884        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
885        "data.{pkg}" exist ; and leave the S/R (return) just after.
886      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
887        + call LAND_READPARMS from packages_readparms.F
888    o pkg/seaice:
889      - remove code that resets useThSice in S/R seaice_readparms and
890        replace it by a warning in S/R seaice_check
891      - remove parameter MULTDIM, replace with nITD and runtime
892        parameter SEAICE_multDim (still hard-wired to nITD if
893        SEAICE_ITD is defined)
894    
895    checkpoint64x (2014/05/24)
896    o verification/lab_sea:
897      - update adjoint and TLM output following changes to pkg/salt_plume
898      - un-do the update after putting back local recip_Cp in few places.
899    o pkg/salt_plume: modifications by An Nguyen:
900      - add capability to do brine rejection (salt-plume) as function of
901        volume+tracers (instead of only salinity tracer).
902      - conserve volume by exchanging volume from each kLev to above to
903        accommodate in-coming brine volume
904      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
905      - switch KPP surf buoyancy due to brine forcing to 3-d
906        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
907      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
908      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
909        in East/West Arctic.
910    o pkg/sbo:
911      - incorporate modifications from Katherine Quinn to enable the use of sbo
912        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
913        output for future testreport verification (unfinished).
914    o pkg/atm_phys:
915      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
916        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
917        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
918    o pkg/seaice
919      seaice_calc_ice_strength.F: modify expression to avoid divisions
920        (affects truncation)
921      seaice_do_ridging.F: clean up the insectarium
922      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
923      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
924      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
925      - add some debugging information and error messages (warnings)
926    o model/src: modifications relatd to atmosphere p*:
927      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
928      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
929        of vertical profile tRef in geopotential background and anomaly.
930      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
931        and pkg/atm_phys.
932      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
933        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
934    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
935    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
936        not used right now, but can be used in BGC packages to fix conservation.
937    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
938        other packages too.
939    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
940        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
941    o model/src:
942      - since we have several heat capacity (even in model/src), define "recip_Cp"
943        as local variable (no longer in common block) to avoid any confusion.
944      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
945    o pkg/exf:
946      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
947        air density as function of air Temp, Humidity and atm pressure.
948    
949    checkpoint64w (2014/05/02)
950    o verification:
951      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
952        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
953        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
954        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
955        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
956    o model/src: for atmosphere in p* coords:
957      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
958      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
959        but not yet activated.
960    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
961      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
962      - this changes the results (but not for any verification experiment, because
963        none tests this), but avoids having an extra field in the restart files
964    o pkg/seaice: remove global variable TICE (not needed)
965      - replace by TICES or local variable where necessary (cost_seaice_test,
966        seaice_diagnostics_state)
967      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
968      - use specific read/write routines for reading and writing individual leves
969        of a multilevel field
970    o pkg/ctrl & model/inc:
971      - move additional anomaly fields of control vars (related to options:
972         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
973        from DYNVARS.h into new header file: CTRL_FIELDS.h
974    o pkg/seaice: some small modifications to the ridging code
975      - make fw2ObyRidge a global variable and add the freshwater flux to
976        seaice_growth
977      - pass actual thickness from seaice_prepare_ridging, so that it is
978        computed only in one place and compute it in the same way as in
979        seaice_growth
980      - initialise more fields in seaice_do_ridging that where cause floating
981        point exceptions over land
982    o pkg/seaice: preparations for ridging code and first real ridging code
983      - move most of "PART 1" of S/R seaice_growth into a new and separate
984        S/R seaice_reg_ridge that will both regularize the state variable after
985        advection call the actual ridging routine;
986      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
987        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
988      - remove ridging code from seaice_advdiff
989      - clean up remaining part 1 of seaice_growth in an attempt to make it
990        more readable (this is probably subjective)
991      - call seaice_itd_redist once in the initialisation phase to have the initial
992        conditions in the correct category
993      - finally: add new ridging routine for ITD code
994    
995    checkpoint64v (2014/04/11)
996    o pkg/ecco:
997      - add runtime parameters mdt[start,end]date[1,2]
998      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
999    o pkg/seaice:
1000      - make deltaC a global variable, so that it can be used in ridging code
1001      - first step towards ridging: introduce new routines that compute
1002        ice strength based on ridging parameters
1003      - add diagnostic for HSNOWITD
1004      - add opnWtrFrac as a global variable (required for ridging scheme)
1005    o pkg/salt_plume + pkg/seaice/seaice_growth.F
1006      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
1007        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
1008    o verification/hs94.1x64x5:
1009      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
1010      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
1011    o autodiff:
1012      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
1013        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
1014        For now, only in pkgs used in verification/hs94.1x64x5.
1015      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
1016        which are specific to TAF/TAMC).
1017      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
1018        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
1019        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
1020      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
1021        building mitgcmuv_ad (make adAll).
1022    o pkg/ecco:
1023      - cost_gencost_seaicev4.F:
1024         reformulate proxy cost as function of sst and local param SEAICE_freeze
1025         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
1026      - add stop statement if old names siv4-[sst,vol] are used
1027      - add snapshots + cost reports for atmospheric longwave
1028      - remove factor 0.1 in front of wtau[u,v]
1029      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
1030         ALLOW_TMI_SST_COST_CONTRIBUTION
1031    o pkg/atm_phys:
1032      - add some diagnostics for Short-wave and for convection S/R.
1033    o pkg/seaice/seaice_growth:
1034      - fix a bug in the lateral melt parameterization for SEAICE_ITD
1035        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
1036      - rearrange loop order for better vector code in the same code block
1037      - rewrite the floeDiameter formula to have fewer divisions
1038      -  (miraculously) none of this changes the results of seaice_itd
1039    o pkg/smooth:
1040      - move param smooth2Ddiffnbt to pkg/ecco
1041    o pkg/salt_plume:
1042      - salt_plume_frac.F:
1043         clean up local param names
1044         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
1045    o pkg/rw:
1046      - add RS version of S/R READ_MFLDS_LEV.
1047    o pkg/streamice:
1048      - fix the restart test by writing/reading pickup_streamice files.
1049    o pkg/seaice:
1050      - refine checks for jfnk-related parameters
1051      - comment out if statement with SEAICEuseIMEX parameter as long as there
1052        is no IMEX code to avoid confusion and surprises
1053    
1054    checkpoint64u (2014/03/07)
1055    o verification/MLAdjust:
1056      - rename secondary test suffix:
1057         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
1058         0.leithD -> AhFlxF  + switch to flux-form
1059         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
1060         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
1061    o pkg/mom_vecinv:
1062      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
1063        to be before mom_calc_visc.F)
1064      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
1065      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
1066        this is simpler for the adjoint and for diagnostics.
1067    o model/src + pkg/momentum:
1068      - add input files for  2-D additional Western and Southern cell-edge wall
1069         (e.g., to add "thin-wall" where it is =1).
1070      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
1071        using 2nd hFacZ that is computed from initial (fix domain) hFac
1072      - known limitations of thin wall implementation: not yet coded for sigma
1073        coords; not working with CD-scheme neither.
1074    o pkg/seaice:
1075      - rename recently introduced parameters from (wrong name) AB to
1076        BDF (backward difference time discretisation)
1077      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
1078    o tools/adjoint_options:
1079      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
1080    
1081    checkpoint64t (2014/02/01)
1082    o pkg/ecco
1083      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
1084        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
1085      - replace hard-coded record number and period which only work for monthly
1086        with read-in runtime param that works for other periods (month,day,year)
1087    o pkg/thsice
1088      - corrected store directive fixes thsice adjoint gradient checks
1089    o genmake2 & testreport:
1090      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
1091        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
1092        Update testreport accordingly. No need to set "export OPENAD=true"
1093        in adjoint_options/adjoint_oad anymore (will be removed later).
1094    o pkg/shelfice:
1095      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
1096        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
1097        so that surface forcing applies to k=kSurf if using pkg/shelfice.
1098    o pkg/ctrl, pkg/grdchk, pkg/ecco:
1099      - Changes to make GENARR more modular (i.e. invisible if not used)
1100    o model/src/temp_integrate.F and salt_integrate.F
1101      - re-include store directives that were removed on Dec 27th.
1102    o model/src/external_forcing_surf.F
1103      - add storage directives for EmPmR and PmEpR to avoid recomputation of
1104        seaice_model in the adjoint that is problematic when seaice_model is
1105        turned off in the adjoint. The resolved issue dated back to July when
1106        EXTERNAL_FORCING_SURF call was moved.
1107        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
1108    o pkg/exf/exf_check.F
1109      - fix a small bug again (originally found by Wentao Liu, now found again)
1110      - streamline error output
1111    o pkg/streamice and aim_v23:
1112      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
1113        Apple's /usr/bin/cpp knows what to do:
1114        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
1115        Target: x86_64-apple-darwin13.0.0
1116    
1117    checkpoint64s (2014/01/05)
1118    o tools/adjoint_options:
1119      - switch to fastopt.net TAF server (instead of default fastopt.de) for
1120        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
1121    o model/src:
1122      - remove some unnecessary TAF storage directives in forward_step.F and
1123        in dynamics.F (note: not always removed by TAF, e.g., double storage
1124        of kappaRU,kappaRV in former version of dynamics.F).
1125    o model/src & pkg/ptracers:
1126      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
1127        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
1128        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
1129      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
1130      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
1131      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
1132    o useSingleCpuInput separates single-CPU input from single-CPU output;
1133        for now only implemented for in exf_interp_read.F
1134    o verification/advect_xy:
1135      - fix missing EXCH call in local version of ini_salt.F and update output.
1136    o momentum diagnostics:
1137      - fix which deltaT is used in Total-Tendency diagnostics.
1138      - fix typo in diagnostics for momentum tendency from AB.
1139    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
1140        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
1141    
1142    checkpoint64r (2013/12/08)
1143    o verification/*/results:
1144      - Update reference output of experiments that were passing with just 13 digits
1145         (make it easier to detect future changes in results)
1146    o model/src & pkg/ptracers:
1147      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
1148        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
1149        to inside ptracers_integrate.F ; remove ptracers_advection.F
1150    o coupling interface pkgs:
1151        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
1152      - change the config check to test the agreement of Ocean Depth
1153        with ATM land/sea mask (instead of ATM orography);
1154      - send to coupler the number of coupler time-steps to do for this run:
1155        this allows to check for consistency and don't need anymore to be
1156        specified in parameter file "data";
1157      in coupler:
1158      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
1159      - improve report to log-file of config setting (pass log-file unit to few S/R)
1160    o pkg/compon_communic:
1161      - add coupling send/receive for non-tiled integer vector;
1162      - add S/R to check and stop if any proc has an error (similar to
1163        eesupp/src/stop_if_error.F but single thread and across Comm_World).
1164    o pkg/exch2:
1165      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
1166        through list of all tiles my proc owns.
1167    o model/src:
1168      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
1169        from rTrans) to simplify dependencies (no need to store rTrans anymore in
1170        calling S/R); this affects AD results at machine truncation level:
1171        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
1172        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
1173    o tools/build_options:
1174      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
1175    o coupling interface pkgs:
1176        [compon_communic, atm_compon_interf & ocn_compon_interf]
1177      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
1178        to each S/R that needs it; remove un-used variables.
1179      - change component tile registration (cpl_register.F in both compon_interf
1180        and mitcomponent_tile_register.F) to pass the full list of tiles
1181        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
1182      - with pkg/exch2: adopt the same convention used for I/O to define mapping
1183        towards coupler global array (unless W2_useE2ioLayOut=F):
1184         a) can now use different tiling between atm & ocn comp.
1185         b) no needs to modify the run-Off map when changing tiling (was needed
1186            even if using the same tiling between atm & ocn).
1187         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
1188            full land tiles); not yet tested.
1189      - check for valid mapping from comp. tile to coupler global array
1190      - improve report of tile registration results to log file.
1191    o pkg/exch2:
1192      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
1193        tile-registration (CPL_REGISTER);
1194      - activate (un-comment) definition and setting of "W2_tileIndex" list to
1195        store the local bi,bj indices of each tile;
1196      - also print bi,bj in local report to log file;
1197      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
1198        Jun 2009 modif of pkg/exch2).
1199    o testing on baudelaire:
1200      - run 2 tests at a time: no significant slow down (since enough cpu) and
1201        get the full set of test done earlier
1202      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
1203    o model/src/thermodynamics.F and routines called from it:
1204      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
1205        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
1206        velocity (outp) by adding bolus velocity.
1207      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
1208        mass transport from velocity + lateral grid cell area
1209      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
1210      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
1211     in thermodynamics.F
1212      - remove k from thermodynamics.F and move it to temp_integrate.F
1213        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
1214        loop).
1215      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
1216        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
1217        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
1218        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
1219      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
1220        global_ocean.90x40x15, tutorial_global_oce_biogeo and
1221        tutorial_tracer_adjsens (+ TLM output).
1222    o tools/OAD_support and (verification/*/) code_oad:
1223      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
1224        module conversion ; remove unneeded CPP_EEOPTIONS.h.
1225      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
1226        version (closer to model/inc/CPP_OPTIONS.h).
1227    o model/src:
1228      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
1229        retired list of parameters (routine FREEZE has been replace by surface
1230        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
1231    o pkg/gmredi:
1232      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
1233        velocity (same scheme but affects machine truncation) for GM_AdvForm.
1234      - update output of FWD experiments: front_relax.bvp,
1235        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
1236    
1237    checkpoint64q (2013/11/17)
1238    o verification:
1239      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
1240        tutorial_global_oce_biogeo and global_ocean.90x40x15.
1241      - generate new output (growth & melt) for seaice_itd experiment after
1242        updating the input pickup_seaice files (previously wrong).
1243    o pkg/cost:
1244      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
1245        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
1246        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
1247          cannot be applied to var in common block).
1248        o allows to get results independent of tile-per-proc setting (if using
1249          slower GLOBAL_SUM_SEND_RECV option).
1250      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
1251        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
1252        forward gradients: update output).
1253      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
1254        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
1255    o pkg/mom_common:
1256      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
1257        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
1258        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
1259        ensure that all field value that are used are set.
1260    o tutorial_deep_convection (smag3d):
1261      - add missing scaling in mom_calc_smag_3d.F;
1262      - set smag3D_coeff in input.smag3d such that results do not change.
1263    o pkg/dic:
1264      - change dic_cost.F to compute cost on each tile first and then apply
1265        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
1266        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
1267      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
1268    o eesupp/src & pkg/mdsio:
1269      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
1270        (from pkg/mdsio) since they are no longer used for tape IO.
1271      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
1272        (+ keep a copy in pkg/atm_ocn_coupler).
1273    o verification/isomip:
1274      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
1275    o tools/build_options:
1276      - optfile linux_amd64_ifort11, fast (no ieee) case:
1277        to get a working restart for all experiments, add "-fp-model source"
1278        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
1279    
1280    checkpoint64p (2013/10/20)
1281    o pkg/autodiff:
1282      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
1283        criteria, return to simple (default) tape IO format.
1284    o pkg/mdsio (+ eesupp/src):
1285      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
1286        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
1287      - fix globalFile and singleCpuIO options using simpler global mapping.
1288      - new pairs of scatter/gather vector S/R (one for each type, generated from
1289        template) corresponding to simpler global mapping.
1290      - adread_write.F: switch to new S/R (but leave old calls commented) and write
1291        to globalFile when parameter globalFiles is set to True.
1292      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
1293    o pkg/autodiff:
1294      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
1295        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
1296        missing, just add a STOP if array type do not match.
1297    o pkg/exf:
1298      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
1299         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
1300         and rename array obsSIce to exf_iceFraction.
1301    o tutorial_deep_convection:
1302      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
1303        for now all in this exp. code dir.
1304      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
1305        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
1306    o eesupp/src:
1307      - added SINGLE_DISK_IO option because reading of parameter files on
1308        very large number of processors did not work with existing set-up
1309    
1310    checkpoint64o (2013/09/25)
1311    o pkg/atm_phys & atm_compon_interf:
1312      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
1313    o tools/build_options:
1314      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
1315        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
1316        remove CPP setting (was identical to genmake2 default).
1317    o pkg/gmredi & model/src: Some updating and work done on the residual model.
1318      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
1319      - fixed up the calculation of the eddy stress and how it is added to the
1320        external forcing via taueddy_external_forcing.F
1321      - at the moment, it is very experimental and only works with the variable eddy
1322        diffusivity calculated in gmredi_k3d.F
1323    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
1324        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
1325    o testreport (& tools/do_tst_2+2):
1326      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
1327    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
1328      - remove CPP='cpp -traditional -P' (this is genmake2 default)
1329      - add switch (for big setups) to use 'medium' memory-model (but leave it
1330        commented out for now). Note: needed with FC 19 to compile big setups.
1331    o pkg/atm_compon_interf:
1332      - regroup per field origin (model & pkgs) the coupling storage routines
1333         (which accumalate in time each coupling field)
1334      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
1335        update accordingly + simplify aim_do_physics.F
1336    
1337    checkpoint64n (2013/08/26)
1338    o pkg/bbl:
1339      - update formulation to reduce dispersion of tracer properties in bbl
1340      - replaced horizontal and vertical transport parameters with velocities
1341      - changes results for verification/global_with_exf.yearly
1342    o verification/halfpipe_streamice:
1343      - change to matrix construction; update both Fwd & AD output.
1344    o verification/tutorial_tracer_adjsens:
1345      - OpenAD test: switch to vector-invariant momentum since fluxform with
1346        rStar causes problems with OpenAD; update output.
1347    o tools:
1348      - genmake2: define a common prefix for all temp-file names ; move them
1349        to local /tmp disk (but would be easy to move them back);
1350      - xmakedepend: apply the same switch for temp-files.
1351    o pkg/offline:
1352      - changes for use with rStar (NLFS): assume that we continue to provide
1353        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
1354        output files) and apply r* scaling at each time-step (function of the time
1355        varying Eta field); use normal pickup files (needed for restart with NLFS).
1356    o adjoint with OpenAD:
1357      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
1358        package openad.  This package has to be compiled for all runs with OpenAD
1359        instead of specifying code_oad_all as a modification directory.
1360      - link the fortran templates from tools/OAD_support to the build directory
1361        for preprocessing to avoid conflicts between different setups compiled
1362        simultaneously and simplify cleanup.
1363    o pkg/exf:
1364      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
1365        main model or other pkgs are exchanged in EXF_MAPFIELDS).
1366    o model/src:
1367      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
1368        (similar to do_fields_blocking_exchanges.F).
1369    o tools/genmake2:
1370      - remove TAF output src code just before calling staf (when not doing a fresh
1371        built, will stop if things go wrong with staf).
1372      - fix target "adobj" (left from TAF version-2 transition)
1373    o pkg/diagnostics:
1374      - add a parameter to track the status of pkg/diagnostics activation;
1375        this replace/extend the use of logical param "settingDiags" (to check
1376        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
1377        New S/R to print error message and stop when pkgStatus is not right.
1378      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
1379    
1380    checkpoint64m (2013/08/13)
1381    o model/inc:
1382      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
1383        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
1384    o pkg/kpp & aim_v23:
1385      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1386    o pkg/seaice:
1387      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
1388        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
1389      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1390    o eesupp/src:
1391      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
1392        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
1393    o switch to TAF version-2:
1394      - add flow directives to "freeze" naming convention for ad-routines that
1395        are used in I/O routines of adjoint state and associated common blocks
1396        that are used in adcommon.h (backward compatible with version-1)
1397      - update all ad-optfiles (in tools/adjoint_options + few local to some
1398        verification exp) to switch to latest TAF version (currently 2.5.5);
1399        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
1400        out except for diva).
1401      - the major change with TAF version-2 is that both the differentiated
1402        routines and the forward routines (new) are returned as part of the TAF
1403        output source code. Update genmake2 accordingly.
1404      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
1405        with version-2 when compared to TLM or FWD gradient); other experiments
1406        output show minor changes (machine truncation level); update the few AD &
1407        TLM output with 12 matching digits only (some prior to version-2 switch).
1408    
1409    checkpoint64l (2013/08/05)
1410    o model/src:
1411      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
1412      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
1413        when using TAF but only if using OpenAD.
1414    o pkg/mom_common+fluxform+vecinv:
1415      - always set horiz. viscosity arrays to background value before calling
1416        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
1417        only when using variable horiz. viscosity (useVariableVisc=T);
1418      - simplify mom_vecinv.F (only 1 block for momViscosity).
1419    o pkg/mom_common: variable horiz. viscosity in NH code
1420      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
1421        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
1422      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
1423        useBiharmonicVisc & useVariableVisc.
1424      - fix old bug (already in 1rst implementation of variable horizontal viscosity
1425        in calc_gw.F, version 1.27, 2006/06/20):
1426        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
1427        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
1428      - change background horiz viscosity in vertical momentum (gW) to always be
1429        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
1430        any type of variable viscosity, e.g., viscAh/4Grid)
1431      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
1432        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
1433        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
1434        default viscAh,viscA4 is zero).
1435    o model/src:
1436      - extend length of drC & recip_drC from Nr to Nr+1.
1437    o Divided Adjoint (DIVA) with MPI:
1438      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
1439      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
1440        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
1441    
1442    checkpoint64k (2013/07/23)
1443    o tools/OAD_support:
1444      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
1445        and remove it from genmake2.
1446    o tools/build_options:
1447      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
1448        MPI_HEADER_FILES list (let genmake2 find the missing headers)
1449    o verification/halfpipe_streamice:
1450      - change to driving stress formulation; update both Fwd & AD output.
1451    o tools/genmake2 and Divided Adjoint with MPI:
1452      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
1453      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
1454      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
1455        Makefile, which is set by genmake2, and check which mpi-headers are needed.
1456        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
1457      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
1458    o testreport:
1459      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
1460        perform additional runs (number of additional runs is "add_DIVA_runs" taken
1461        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
1462    o verification/lab_sea (AD test):
1463      - change to test Divided Adjoint Run in this set-up (both standard AD test
1464        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
1465    o pkg atm_ & ocn_compon_interf:
1466      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
1467        staggerTimeStep implementation) and disable (retired) corresponding
1468        parameter.
1469    o pkg/offline:
1470      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
1471      - add S/R OFFLINE_CHECK to print offline parameter summary
1472        and stop if loading a file that is not used;
1473      - enable to calculate GMRedi tensor, KPP mixing and convective index
1474        when the corresponding file(s) is/are not specified (but pkg is used).
1475      - comment out resetting of monitorFreq (to endTime) since it still useful
1476        for monitoring CFL numbers and checking offline fields.
1477    o OpenAD:
1478      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
1479        smaller standard output) and generate new (smaller) output (on baudelaire
1480        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
1481    o model/src:
1482      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
1483        (where external_forcing_adjust was called) and change list of arguments;
1484      - merge external_forcing_adjust.F into external_forcing_surf.F
1485      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
1486        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
1487        previously in file "balance_relax.F", now removed); remove corresponding
1488        arrays in FFIELDS.h.
1489      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
1490        a hack for getting back surfaceForcingS (loaded from file) when using
1491        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
1492      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
1493        (was getting only 11 digits for AD-grad, due to different truncation
1494         error in AD code).
1495    
1496    checkpoint64j (2013/07/04)
1497    o pkg/offline:
1498      - to enable the use of other features with pkg offline (e.g., obcs),
1499        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
1500      - comment out "allowFreezing" (now active) in 2 offline testing exp.
1501    o pkg/exf ALLOW_RUNOFTEMP
1502      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
1503      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
1504      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
1505    o pkg/atm_phys:
1506      - allows to add some damping on uVel,vVel (strength only function of k).
1507    o verification, ad-tests:
1508      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
1509        global_ocean_ebm and offline_exf_seaice.thsice.
1510    o verification/halfpipe_streamice:
1511      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
1512        flux input boundary conditions to be ignored; a fix for this bug changed
1513        verification results for forward test.
1514      - add adjoint test.
1515    o pkg/ptracers:
1516      - allow to restart without SOM pickup (resetting SOM to zero).
1517    o pkg/gmredi:
1518      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
1519      - It uses mixing length theory and suppression by steering level effects to
1520        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
1521        to JPO, for more details).
1522      - It also uses the diffusivity to calculate an eddy induced streamfunction
1523        based on a PV closure (rather than a buoyancy closure as in GM).
1524      - New files added to pkg/gmredi:
1525        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
1526          induced overturning streamfunction (called from gmredi_calc_tensor)
1527        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
1528          for use in gmredi_k3d
1529        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
1530          the eddy diffusivity
1531    
1532    checkpoint64i (2013/06/18)
1533    o pkg/cheapaml:
1534      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
1535        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
1536        with pkg/cheapaml.
1537    o utils/python: add subpackage for cubed sphere function, first example is
1538        simple cs.pcol to plot 2D fields on a map
1539    o pkg/streamice:
1540      - This is a new package in MITgcm, which solves dynamic equations for ice
1541         sheets and ice streams
1542      - At the moment it is independent of atmosphere/ocean dynamics, or any
1543        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
1544        ed that this will change)
1545      - There is a new verification exercise that tests it, halfpipe_streamice,
1546        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
1547        rectangular embayment
1548      - halfpipe_streamice is forward-only for now, will have TAF test soon
1549      - for questions, email dgoldber@mit.edu
1550    o pkg/thsice:
1551      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
1552        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
1553      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
1554         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
1555      - allow precip from pkg/cheapaml to make snow over seaice.
1556    o pkg/cfc:
1557      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
1558      - remove atmos CFC 2-D arrays from common bloc (now local variables)
1559      - change some hard-coded constant to run time parameter for reading and
1560        and interpolating atmospheric CFC ; keep same default as previously.
1561      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
1562      - put arguments in standard order: myTime, myIter, myThid
1563      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
1564        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
1565      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
1566      - new routine to print summary of CFC params and check for consistency.
1567    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
1568      similar to thsice_advdiff.
1569      Note that for the B-grid case the routine parameters uc/vc are overwritten.
1570    o pkg/cfc:
1571      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
1572        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
1573      - fix interpolation of atmphspheric CFC between Sorthern and Northern
1574        hemisphere value.
1575    o pkg/seaice:
1576      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
1577    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
1578                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
1579      - requires an additional time level that is stored in the pickup
1580      - you can start with AB2 from a pickup without this time level with
1581        pickupStrictlyMatch = .false.
1582    
1583    checkpoint64h (2013/05/26)
1584    o pkg/cheapaml:
1585      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
1586        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
1587      - consistent treatment of uWind,vWind location: assume everywhere in
1588        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
1589        (Note: was already the case for Tair,Qair advection);
1590        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
1591      - compute diabatic forcing only in the interior (excluding overlap regions)
1592      - fill in array "Qsw" (for short-wave heating);
1593      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
1594        before any update (consistent with MITgcm state var diagnostics);
1595      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
1596        non periodic ; + adjusted for uWind,vWind (C-grid).
1597    o pkg/seaice:
1598      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
1599        add explicitly pkg/exf in experiments that currently use pkg/seaice.
1600      - allows to compile pkg/seaice without pkg/exf.
1601    o tools/OAD_support:
1602      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
1603        of array "ourStepOf" in function rvNextAction (revolve.F90).
1604    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
1605      - change pkg name (to be used with other atmospheric physics pkg)
1606        but by-pass CVS when making the new pkg so that we keep the CVS history.
1607    o pkg/offline:
1608      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
1609        (previously called from pkg/dic_surfforcing_init.F)
1610    o model/src:
1611      - re-order sequence of calls within packages_init_variables.F, using
1612        standard order, except for:
1613         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
1614         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
1615    o new pkg: atm_phys
1616      - add entry point and source code (previously in contrib
1617          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
1618        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
1619      - re-order sequence of calls within packages_readparms.F,
1620         packages_init_fixed.F and packages_write_pickup.F
1621        (but skip packages_init_variables.F because of TAF issues).
1622      - update contrib/*/atm_gray/ experiment.
1623    o pkg/seaice (ITD code):
1624      - simplify and fix the writing of pickup-files for ITD case
1625    o pkg/seaice (ITD code):
1626      - introduce floe size dependent lateral melt for ITD case;
1627      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
1628      - update seaice_itd experiment main output.
1629    o pkg/thsice:
1630      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
1631        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
1632        changed accordingly pkg/atm2d.
1633    
1634    checkpoint64g (2013/05/01)
1635    o pkg/exf ALLOW_RUNOFTEMP
1636      - if defined,  river and glacier runoff temperature can be read-in from
1637        runoftempfile; runoftempfile needs to have same format as runofffile
1638    o pkg/thsice (& pkg/bulk_force):
1639      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
1640        for energy content of Precip + RunOff & Evap (like with pkg/exf).
1641      - change computation domain to always be the interior (without overlap).
1642      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
1643    o verification/tutorial_global_oce_biogeo:
1644      - add preliminary OpenAD setup (still has problems)
1645    o pkg/seaice:
1646      - turn some parameters for choosing the convergence criterion of
1647        the inexact Newton method (JFNK) into runtime parameters for convenience
1648      - clean up seaice_calc_viscosities.F: remove/retire two options for
1649        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
1650        the results of lab_sea/input because a division has been replaced by
1651        a multiplication with the reciprocal (sumNorm)
1652      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
1653        convergence of solver (changes results, of course), and to test some
1654        new features
1655    o model/src:
1656      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
1657      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
1658      - move forcing adjustment (balancing surface forcing) in specific S/R
1659        where might also be applied exchanges (if needed) to forcing arrays.
1660    o pkg/shelfice:
1661      - allow to specify the Ice-Shelf mass per unit area (instead of
1662        shelficeLoadAnomaly) and do the conversion from one to the other
1663      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
1664        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
1665        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
1666        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
1667      - update isomip experiment forward output (get machine truncation error
1668        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
1669    o verification/offline_exf_seaice:
1670      revise data.seaice in input.thermo and input_ad and update results accordingly
1671        HO = 0.2, SEAICE_areaLossFormula = 2,
1672        SEAICE_growMeltByConv = .TRUE.,
1673        SEAICE_doOpenWaterMelt = .TRUE.,
1674      Improve consistency with input.thsice and fix the spurious 500m ice corners
1675    o verification/global_ocean.cs32x15:
1676      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
1677        in icedyn (thsice+seaice-dyn) test and update output.
1678    o verification/offline_exf_seaice:
1679      - adjust list of tested variables (with testreport) and update
1680        standard test output with better slection of monitored fields.
1681    o pkg/cd_code:
1682      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
1683        experiment lab_sea.hb87
1684    o tools/genmake2:
1685      - change default makedepend from the system default to tools/xmakedepend:
1686        When no makedepend is specified, select tools/xmakedepend it the test pass,
1687        otherwise select the system default (if exist and pass the test) or
1688        try to build cyrus-makedepend ; stop if none of the 3 works.
1689    o pkg/exf & pkg/thsice:
1690      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
1691        for energy content of Precip + RunOff & Evap. Assumes:
1692       1) Rain has same temp as Air.
1693       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
1694       3) Run-Off comes at the temp of surface water (with same Cp)
1695       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
1696        put directly into Latent Heat flux & should use water-vapor heat capacity.
1697       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
1698        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
1699    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
1700        (compile when SEAICE_ALLOW_JFNK is defined)
1701    o pkg/thsice:
1702      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
1703        implementation): move THSICE_AVE call after the advection (called directly
1704        from thsice_do_advect.F).
1705    o verification/global_ocean.90x40x15 and OpenAD:
1706      New experiment for OpenAD is identical to the one in input_ad except that
1707        multiDimAdvection=.FALSE.,
1708      There is still an issue with this.
1709    o pkg/thsice:
1710      - account for ice velocity (ocean relative velocity) in turbulent heat flux
1711        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
1712        and offline_exf_seaice (main test).
1713    
1714    checkpoint64f (2013/03/31)
1715    o verification/OpenAD:
1716      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
1717    o verification/isomip, pkg/shelfice and OpenAD:
1718      - add OpenAD setup to this exp and make shelfice package work with OpenAD
1719    o verification/tutorial_global_oce_biogeo:
1720      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
1721    o verification/offline_exf_seaice:
1722      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
1723    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
1724      - add OpenAD setup to this exp and make ptracers package work with OpenAD
1725    o pkg/seaice/seaice_evp.F:
1726       mask the asymmetric contribution of the ice-ocean stress (when
1727       the turningAngle is non-zero) over open water to avoid stripes
1728       in the EVP-solutions after many EVP-substeps. This does not change
1729       the verification experiment (because turningAngle=0 in that experiment),
1730       but will affect other EVP solutions with turningAngle.ne.0
1731    o verification, AD & TLM output:
1732      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
1733        additions and multiplications which affect results at machine truncation
1734        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
1735        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
1736        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
1737        digits of matching.
1738    o pkg/seaice:
1739       modify lsr-algorithm so that it vectorizes AND converges by using a
1740       "zebra" method: split vector loop into two with step size 2; this
1741       solves a general convergence problem for the JFNK solver on a vector
1742       computer. It has the potential to even improve convergence for
1743       non-vector machines, but it does change the results so it is turned
1744       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
1745       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
1746    
1747    checkpoint64e (2013/03/05)
1748    o pkg/ecco and several verification experiments:
1749       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
1750       from ecco package, and revert to unified routine in model/src/
1751       Adjust verification experiments accordingly, especially gloal_oce_llc90
1752       Should conclude long-standing work by Gael to reconsile the_main_loop with
1753       ECCO and will enable OpenAD's revolve loop in ECCO setup.
1754    o pkg/generic_advdiff:
1755      - implement compressible flow method for multi-dim advection (similar to
1756        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
1757        TAF generates many recomputations) to use it; no yet coded with implicit
1758        vertical advection.
1759      - change experiment advect_cs (new output) and advect_xy (same output)
1760        to test compressible flow multi-dim advection.
1761    o pkg/generic_advdiff:
1762      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
1763        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
1764    o pkg/seaice:
1765      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
1766        bug affects two verification experiments (lab_sea and lab_sea.hb87),
1767        recover old (wrong) results by setting noSlipFac = 2. in
1768        seaice_calc_strainrates.F;
1769      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
1770      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
1771        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
1772      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
1773    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
1774      - new subroutines seaice_lsr_tridiagu/v
1775      - introduce loop bounds i/jmin/max to be able to use a restricted
1776        additive Schwarz method, but not used for now.
1777      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
1778      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
1779    o OpenAD support
1780       Reorganize S/R call for overall time-stepping loop to facilitate
1781       OpenAD revolve loop replacement
1782       (new S/R main_do_loop.F)
1783    o model/src:
1784      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
1785      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
1786        ADAMS_BASHFORTH2.
1787    o pkg/cheapaml:
1788      - add new parameter (default=F, same as before) to disable full domain
1789        (including land) periodicity in X & Y dir.
1790      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
1791        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
1792        into single S/R CHEAPAML_TIMESTEP.
1793    
1794    checkpoint64d (2013/02/17)
1795    o pkg/monitor (angular momentum):
1796      - do not add Eta contribution to the total AM if using rigid-lid;
1797      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
1798      - horizontal discretisation: compute Zonal wind contribution separately for
1799        each component (instead of from cell centered averaged) and use the 4
1800        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
1801      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
1802        FreeSurf) if using vectorInvariant momentum.
1803    o model/src (horizontal grid):
1804      - move initialisation of all horizontal grid arrays to null value
1805        from specific horizontal grid S/R to main S/R INI_GRID;
1806      - add 2 new arrays to project model C-grid velocity on to zonal direction
1807        (similar to AngleCosC & -AngleSinC but at U and V point location) and
1808        compute them in S/R CALC_GRID_ANGLES.
1809    o pkg/seaice: replace a hard coded parameter by a runtime parameter
1810        SEAICE_JFNK_tolIter
1811    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
1812        preconditioner for JFNK (run LSR into the overlaps as far as possible,
1813        i.e OLx/y-2, but overwrite the solution in the overlaps)
1814      - extend loop range in seaice_calc_viscosity
1815      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
1816      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
1817      - slightly modify loops in tridiagonal solver lsr-preconditioner
1818      - by default remove the extra exchange in seaice_preconditioner with a
1819        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
1820      - modify offline_exf_seaice so that old results without RAS are reproduced
1821        for output.dyn_jfnk.txt
1822      in seaice_fgmres.F (unrelated to RAS)
1823      - add a cpp-flag option for a re-ordered mapping (potentially more
1824        efficient), but because this changes the results, turn it off by
1825        default
1826      - replace the save statement by local common blocks
1827    o utils/matlab:
1828      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
1829      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
1830        instead of local script "load_cs.m".
1831    o pkg/seaice:
1832      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
1833        to the scalarProductMetric and the unrolling. By chance this does not
1834        change the verification experiment, because of the particular domain
1835        decomposition
1836    o pkg/diagnostics:
1837    - change default missing_value from UNSET_RL to -999.    - change default missing_value from UNSET_RL to -999.
1838  o pkg/layers: improve vectorization of layers_fluxcalc.F  o pkg/layers: improve vectorization of layers_fluxcalc.F
