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

394        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
395      - cost_gencal.F (new) : determine filnames and records.
396      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
397      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
398        and exploit the above functions leading to more compact code.
399      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
400      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
401        using_ers, using_gfo, using_mdt is now only defined within gencost)
402    o pkg/ecco: extend generic cost capabilities
403      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
404        capabilities via gencost_preproc (+ _c,_i,_r related params),
405        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
406        gencost_outputlevel arguments to cost_generic
407      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
408        and active_read, making room for gencost_preproc to take effect.
409        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
410      - pkg/ecco/cost_generic.F :
411        compute and store misfit maks*(model-data) in localdif that is
412        then used in cost and for output, output misfit if outlev.GT.0
413      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
414        rather gencost_barfile for deciding whether to write barfile
415      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
416      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
417        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
418      - pkg/ecco/ecco_summary.F : report gencost variables
419      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
420    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
421    o pkg/ecco: internal re-organization
422      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
423        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
424        mv relevant variables definition from ecco_cost.h to ecco.h,
425        make sure gencost routines only include ecco.h)
426      - throughout : add missing CCP switches, rm unused variables,
427        and rm un-necessary CPP switches
428      - throughout gencost routines : replace modelstartdate with
429        gencost_startdate when needed
430      - cost_bp_read.F : use arguments, instead of common blocs
431        so that it can be used also by (new) cost_gencost_bpv4.F
432      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
433      - ecco_phys.F : compute etanFull
434      - ecco_readparms.F : rename using_topex as using_tpj, add
435        bpv4-grace to gencost list, initialize added parameters
436      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
437    
438    checkpoint65e (2014/09/28)
439    o pkg/obcs:
440      - replaced the just-added CPP options with run-time variables
441        (see pkg/obcs/OBCS_PARAMS.h for details)
442    o pkg/obcs:
443      - add additional CPP options for sponge boundary layers
444        (see pkg/obcs/OBCS_OPTIONS.h for details)
445    o pkg/atm_phys:
446      - implement simple (obliquity only, assuming circular planet orbit)
447        seasonal cycle for incoming insolation ; used when run-time parameter
448        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
449    o pkg/exf, pkg/ecco, pkg/ctrl:
450      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
451      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
452      - implement gentim2d for xx_tauu, xx_tauv
453    o pkg/ctrl, pkg/ecco :
454      - fix and complement the generic controls implementation
455    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
456        pkg/shelfice/shelfice_thermodynamics.F,
457        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
458        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
459      - add weight in CTRL_GET_GEN calls
460    o pkg/ctrl :
461      - ctrl_get_gen.F : add weight as input parameter, and apply
462        it directly rather than using smooth_correl2Dw (to be retired).
463      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
464    o pkg/ctrl :
465      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
466        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
467      - re-activate ctrl_summary (call in ctrl_init.F)

475    
476    checkpoint65d (2014/09/15)
477    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
478      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
479        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
480    o pkg/ctrl/ctrl_map_ini_genarr.F :
481      - remove compilation failure
482      - replace hard coded example
483      - use ctrl_map_ini_gen2D, 3D

501      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
502    o ecco/ecco_ad_diff.list :
503      - add ecco_init_varia.f
504    o ecco/ecco_init_varia.F
505      - new routine
506    o pkg/streamice:
507      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
508        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
509      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
510    o pkg/generic_advdiff:
511      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
512    o pkg/exf:
513      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
514         xxg_precip capability
515      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
516    o pkg/ctrl:
517      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
518    o model/src/load_fields_driver.F :
519      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
520        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
521    o OpenAD verification experiments:
522      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
523        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
524        for now, only in pkgs used in OpenAD verification experiments.
525      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
526        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
527        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
528        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
529    o OpenAD verification tests:
530      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
531      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
532        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
533      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
534        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
535    o model/src & generic_advdiff:
536      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
537        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
538        dynamics requires valid tracer forcing only over tile interior but, for
539        some diagnostics, may need to extend it over 1 point in tile halo region.
540      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
541        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
542        setting in temp/salt/ptracer_integrate.F
543    o pkg/dic:
544      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
545        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
546        in gchem_forcing_sep.F
547    o pkg/autodiff & obcs:
548      - add storage of current OB values for U & V (was already done for T & S).
549    
550    checkpoint65c (2014/08/30)
551    o pkg/dic:
552      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
553        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
554        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
555    o verification:
556      - new experiment testing OBCS and DIC pkgs, using params & output from
557        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
558        passage: take OBCS from the last year of a 2 yrs simulation and initial
559        conditions from t=1.yr while keeping the same forcing.
560    o model/src:
561      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
562        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
563    o pkg/diagnostics (Stats-Diags):
564      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
565        a) refine region where stats are computed, excluding where arrhFac=0 ;
566        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
567        c) extend regional stats over the region edges (for U or V pt location).
568    o pkg/gchem:
569      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
570        pkg/dic is currently changing/updating ptracers values beyond the OB).
571    o verification (hs94):
572      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
573        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
574        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
575        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
576    o pkg/ptracers:
577      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
578        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
579      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
580        with AB-2 code (so that it get tested).
581    o model/src:
582      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
583        with AB-2 code (previously only available with AB-3 code).
584        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
585        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
586        there, by calling CYCLE_AB_TRACER).
587    o pkg/generic_advdiff:
588      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
589        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
590        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
591        S/R temp/salt/ptracers_integrate.F
592    o model/src & pkg/ptracers:
593      - remove common block variables gT,gS (in DYNVARS.h), except when
594         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
595      - remove common block variable gPtr.
596    o model/src & pkgs:
597      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
598         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
599         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
600         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
601      + change accordingly all calling S/R.
602      - use local temperature/salinity/ptracer tendency array (without bi,bj)
603        in S/R temp/salt/ptracers_integrate.F
604    o pkg/seaice:
605      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
606        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
607      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
608        in seaice_lsr
609      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
610        in s/r seaice_lsr_calc_coeffs
611    o pkg/mdsio:
612      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
613        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
614        too long (e.g., > MAX_LEN_FNAM/2 )
615    
616    checkpoint65b (2014/08/12)
617    o pkg/matrix:
618      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
619    o model/src:
620      - fix initialisation of geothermalFile; compile geothermal-flux code in
621        natl_box verification experiment.
622    o model/src & pkg/down_slope:
623      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
624      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
625        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
626        results at machine truncation level: update output of experiments
627        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
628    o pkg/diagnostics (Stats-Diags):
629      - do not cumulate the full volume when DIAGNOSTICS_FILL is
630        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
631        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
632        times (but Min,Max and StD are still wrong).
633    o model/src:
634      - add geothermal flux forcing: read in ini_forcing.F as time-constant
635        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
636    o model/src:
637      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
638        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
639        arrays are already updated while adjustments (filters, conv.adjustment) are
640        still applied later, in S/R TRACERS_CORRECTION_STEP.
641    o model/src:
642      - store in common bloc array "rhoInSitu" the virtual potential temperature
643        anomaly that is used to compute geopotential: this make the atmos code
644        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
645    o pkg/seaice/seaice_lsr.F
646      - rename integer variable ilcall to ipass (that's what it is called
647        in the residual diagnostics
648      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
649        default) for improved non-linear convergence of the first few steps
650      - adjust a few comments and add new ones to explain some of the store
651        directives
652    o pkg/generic_advdiff (& ptracers):
653      - re-work the code to check for valid advection scheme and for minimum
654        size of overlap (now stored in local common bloc in gad_advscheme.F)
655  o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics  o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
