4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
8      - remove xx_genarr2d_numsmooth etc
9      - use xx_genarr2d_preproc etc instead
10      - carry out smooth_correl2D at initialization
11      stage rather than during time stepping.
12      - get smoothOpNb from xx_gentim2d_preproc
13    o global_oce_cs32 :
14      - add test of generic ecco capabilities.
15    o pkg/exf/exf_getsurfacefluxes.F :
16      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
17    o pkg/ctrl,ecco :
18      -  omit un-necessary arguments to ctrl_cost_gen.F
19      unless ECCO_CTRL_DEPRECATED is defined.
20    o pkg/seaice: add diagnostics for Delta (deformation parameter)
21    o model/src:
22      - when ALLOW_3D_DIFFKR is defined, add a STOP if any of the vertical
23        diffusivity (background) is specified but ignored.
24    o verification:
25      - in testreport, convert hostname to lower case for default output dir name
26    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
27    o pkg/dic: add modifications from Hajoon:
28      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
29      - light attenuation: add self-shading effect by climatological Chlorophyll
30        (read from file).
31    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
32        compiles when SEAICE_ALLOW_DYNAMICS is undefined
33    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
34        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
35        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
36        approach where CPP_OPTIONS.h includes an omnipotent
37        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
38    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
39        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
40    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
41        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
42        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
43    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
44      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
45      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
46      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
47      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
48    o pkg/ctrl,ecco,exf :
49      - remove variables associated with NON-generic costs,
50        unless ECCO_CTRL_DEPRECATED is defined.
51      - remove NON-generic NON-obcs controls,
52        unless ECCO_CTRL_DEPRECATED is defined.
53    o pkg/ctrl : added ctrl_local_params.h
54    o pkg/ecco : added ecco_local_params.h
55    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
56        experiments, which will progressively be removed once the
57        experiments are revised to use only generic controls/costs.
58    
59    checkpoint65f (2014/10/13)
60    o pkg/ctrl, ecco, seaice : minor changes in headers
61    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
62        cost function and control capabilities added since checkpoint65c.
63    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
64    o pkg/ecco: increase modularity and improve logic
65      - ecco_toolbox.F (new) : basic operations that are often used,
66        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
67        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
68      - cost_gencal.F (new) : determine filnames and records.
69      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
70      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
71        and exploit the above functions leading to more compact code.
72      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
73      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
74        using_ers, using_gfo, using_mdt is now only defined within gencost)
75    o pkg/ecco: extend generic cost capabilities
76      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
77        capabilities via gencost_preproc (+ _c,_i,_r related params),
78        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
79        gencost_outputlevel arguments to cost_generic
80      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
81        and active_read, making room for gencost_preproc to take effect.
82        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
83      - pkg/ecco/cost_generic.F :
84        compute and store misfit maks*(model-data) in localdif that is
85        then used in cost and for output, output misfit if outlev.GT.0
86      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
87        rather gencost_barfile for deciding whether to write barfile
88      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
89      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
90        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
91      - pkg/ecco/ecco_summary.F : report gencost variables
92      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
93    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
94    o pkg/ecco: internal re-organization
95      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
96        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
97        mv relevant variables definition from ecco_cost.h to ecco.h,
98        make sure gencost routines only include ecco.h)
99      - throughout : add missing CCP switches, rm unused variables,
100        and rm un-necessary CPP switches
101      - throughout gencost routines : replace modelstartdate with
102        gencost_startdate when needed
103      - cost_bp_read.F : use arguments, instead of common blocs
104        so that it can be used also by (new) cost_gencost_bpv4.F
105      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
106      - ecco_phys.F : compute etanFull
107      - ecco_readparms.F : rename using_topex as using_tpj, add
108        bpv4-grace to gencost list, initialize added parameters
109      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
110    
111    checkpoint65e (2014/09/28)
112    o pkg/obcs:
113      - replaced the just-added CPP options with run-time variables
114        (see pkg/obcs/OBCS_PARAMS.h for details)
115    o pkg/obcs:
116      - add additional CPP options for sponge boundary layers
117        (see pkg/obcs/OBCS_OPTIONS.h for details)
118    o pkg/atm_phys:
119      - implement simple (obliquity only, assuming circular planet orbit)
120        seasonal cycle for incoming insolation ; used when run-time parameter
121        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
122    o pkg/exf, pkg/ecco, pkg/ctrl:
123      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
124      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
125      - implement gentim2d for xx_tauu, xx_tauv
126    o pkg/ctrl, pkg/ecco :
127      - fix and complement the generic controls implementation
128    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
129        pkg/shelfice/shelfice_thermodynamics.F,
130        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
131        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
132      - add weight in CTRL_GET_GEN calls
133    o pkg/ctrl :
134      - ctrl_get_gen.F : add weight as input parameter, and apply
135        it directly rather than using smooth_correl2Dw (to be retired).
136      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
137    o pkg/ctrl :
138      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,

150    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
151      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
152        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
153    o pkg/ctrl/ctrl_map_ini_genarr.F :
154      - remove compilation failure
155      - replace hard coded example

175    o ecco/ecco_ad_diff.list :
176      - add ecco_init_varia.f
177    o ecco/ecco_init_varia.F
178      - new routine
179    o pkg/streamice:
180      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
181        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
182      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
183    o pkg/generic_advdiff:
184      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
185    o pkg/exf:
186      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
187         xxg_precip capability
188      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
189    o pkg/ctrl:
190      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
191    o model/src/load_fields_driver.F :
192      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
193        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
194    o OpenAD verification experiments:
195      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
196        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
197        for now, only in pkgs used in OpenAD verification experiments.
198      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
199        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
200        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
201        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
202    o OpenAD verification tests:
203      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
204      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
205        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
206      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
207        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
208    o model/src & generic_advdiff:
209      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
210        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
211        dynamics requires valid tracer forcing only over tile interior but, for
212        some diagnostics, may need to extend it over 1 point in tile halo region.
213      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
214        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
215        setting in temp/salt/ptracer_integrate.F
216    o pkg/dic:
217      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
218        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
219        in gchem_forcing_sep.F
220    o pkg/autodiff & obcs:
221      - add storage of current OB values for U & V (was already done for T & S).
222    
223    checkpoint65c (2014/08/30)
224    o pkg/dic:
225      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
226        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
227        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
228    o verification:
229      - new experiment testing OBCS and DIC pkgs, using params & output from
230        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
231        passage: take OBCS from the last year of a 2 yrs simulation and initial
232        conditions from t=1.yr while keeping the same forcing.
233    o model/src:
234      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
235        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
236    o pkg/diagnostics (Stats-Diags):
237      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
238        a) refine region where stats are computed, excluding where arrhFac=0 ;
239        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
240        c) extend regional stats over the region edges (for U or V pt location).
241    o pkg/gchem:
242      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
243        pkg/dic is currently changing/updating ptracers values beyond the OB).
244    o verification (hs94):
245      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
246        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
247        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
248        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
249    o pkg/ptracers:
250      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
251        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
252      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
253        with AB-2 code (so that it get tested).
254    o model/src:
255      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
256        with AB-2 code (previously only available with AB-3 code).
257        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
258        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
259        there, by calling CYCLE_AB_TRACER).
260    o pkg/generic_advdiff:
261      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
262        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
263        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
264        S/R temp/salt/ptracers_integrate.F
265    o model/src & pkg/ptracers:
266      - remove common block variables gT,gS (in DYNVARS.h), except when
267         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
268      - remove common block variable gPtr.
269    o model/src & pkgs:
270      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
271         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
272         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
273         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
274      + change accordingly all calling S/R.
275      - use local temperature/salinity/ptracer tendency array (without bi,bj)
276        in S/R temp/salt/ptracers_integrate.F
277    o pkg/seaice:
278      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
279        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
280      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
281        in seaice_lsr
282      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
283        in s/r seaice_lsr_calc_coeffs
284    o pkg/mdsio:
285      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
286        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
287        too long (e.g., > MAX_LEN_FNAM/2 )
288    
289    checkpoint65b (2014/08/12)
290    o pkg/matrix:
291      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
292    o model/src:
293      - fix initialisation of geothermalFile; compile geothermal-flux code in
294        natl_box verification experiment.
295    o model/src & pkg/down_slope:
296      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
297      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
298        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
299        results at machine truncation level: update output of experiments
300        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
301    o pkg/diagnostics (Stats-Diags):
302      - do not cumulate the full volume when DIAGNOSTICS_FILL is
303        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
304        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
305        times (but Min,Max and StD are still wrong).
306    o model/src:
307      - add geothermal flux forcing: read in ini_forcing.F as time-constant
308        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
309    o model/src:
310      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
311        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
312        arrays are already updated while adjustments (filters, conv.adjustment) are
313        still applied later, in S/R TRACERS_CORRECTION_STEP.
314    o model/src:
315      - store in common bloc array "rhoInSitu" the virtual potential temperature
316        anomaly that is used to compute geopotential: this make the atmos code
317        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
318    o pkg/seaice/seaice_lsr.F
319      - rename integer variable ilcall to ipass (that's what it is called
320        in the residual diagnostics
321      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
322        default) for improved non-linear convergence of the first few steps
323      - adjust a few comments and add new ones to explain some of the store
324        directives
325    o pkg/generic_advdiff (& ptracers):
326      - re-work the code to check for valid advection scheme and for minimum
327        size of overlap (now stored in local common bloc in gad_advscheme.F)
328    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
329      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
330      - add an auxilliary variable "bet" and fix store directives and keys in
331        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
332        less exact gradients in my tests); but there are still
333        recomputation warning (although gradients are sort of OK), when
334        SEAICE_LSR_VECTORIZE is not defined, so this flag and
335        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
336      - update verification experiments lab_sea.
337      - change some comments in S/R seaice_calc_viscosities
338    o model/src:
339      - if staggerTimeStep=T, always apply exchange to velocity field in
340        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
341        (independent of using multi-dim advection or not); no effect on FWD run
342        but affects AD results (at machine truncation level): update output of
343        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
344        and isomip (oad: 12.d).
345    o pkg/generic_advdiff:
346      - stop if doAB_onGtGs is set to FALSE but ignored
347      - refine warning related to stability of tracer time-stepping
348        regarding internal wave dynamics.
349      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
350        on staggerTimeStep & implicitIntGravWave (will now get a warning
351        if potentially unstable).
352    o pkg/kl10:
353      - add new pkg "kl10" for mixing due to internal wave breaking, from
354        http://www.sciencedirect.com/science/article/pii/S1463500310000144
355        (contribution from Jody Klymak), tested in verification experiment
356        verification/internal_wave/input.kl10/
357    o isomip experiment:
358      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
359        (input.htd) and update the output.
360    o cd_code experiments:
361      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
362        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
363        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
364        update the corresponding output.
365    o pkg/seaice:
366      - reduce the number of include files and store directives in
367        S/R seaice_lsr_tridiagu/v
368      - change the order of loops in one case in S/R seaice_lsr_tridiagv
369        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
370        get rid off one store directive (a TAF bug?)
371      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
372        S/R seaice_lsr_tridiagv to change the loop range for consistency
373      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
374      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
375        S/R seaice_lsr_tridiagu/v (requires update of
376        offline_exf_seaice/input.dyn_jfnk)
377    
378    checkpoint65a (2014/07/27)
379    o model/src:
380      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
381        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
382        (topo in p-coords, ice-shelf in z-coords); update output of experiments
383        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
384    o model/src:
385      - collect momentum forcing tendency into local 2-D array (passed as argument
386        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
387        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
388        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
389      - collect T & S forcing tendency into local 2-D array (passed as argument to
390        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
391        affects results at machine truncation level (e.g., ocean: if using
392        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
393        correction due to vertical advection).
394      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
395        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
396        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
397        obcs_ctrl (ad & fwd grd @ 12 & 7).
398    o pkg/ptracers & diagnostics:
399      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
400        title (to avoid some unexpected truncation); sort out ptracers diags units.
401      - collect ptracer forcing tendency into local 2-D array (passed as argument
402        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
403    
404    checkpoint65 (2014/07/18)
405    o pkg/fizhi:
406      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
407        affects results at machine truncation level. Update output of experiments
408        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
409    o pkg/seaice: more clean up
410      - rename TAF common block tapes to be more consistent and remove
411        unnecessary duplicates
412      - add store directives to remove more recomputations, but use smaller
413        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
414        The idea behind this flag is to reduce the memory footprint when the
415        adjoint of the LSR is not required. As of now, defining the flag
416        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
417        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
418        For experiment offline_exf_seaice, this means on a linux box with gfortran
419        nearly a factor of 10 (but keep in mind there is mostly seaice code in
420        this experiment):
421        > size mitgcmuv_ad
422        text    data        bss     dec        hex  
423        5100659 1216  220458952  225560827  d71c8fb
424        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
425        but only a moderate increase of 36% for global_ocean.cs32x15:
426        text    data        bss     dec        hex
427        6695027 1648 1014578664 1021275339 3cdf6ccb
428        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
429      - note: there are still recomputations in global_ocean.cs32x15 and
430        offline_exf_seaice and the gradient agreement changes (gets a
431        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
432      - in general, the AD gradients still are wrong
433    o OpenAD
434      - clean up code_oad/ directories somewhat by moving files
435        dontCompile, dontTransform, keepOriginal to OAD_support/
436    o model/src:
437      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
438        (not currently tested): add dissipation terms before NLFS rescaling of
439        tendencies (previously done after).
440    o pkg/diagnostics:
441      - write stats-diags in ascii file with more digits (same as in monitor).
442    o pkg/down_slope:
443      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
444        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
445    o model/src:
446      - new file "apply_forcing.F" containing all the code previously in
447        external_forcing.F, but with new argument list: pass, as new argument,
448        the current level tendency array to update (instead of a direct update
449        of the common bloc array). Change the corresponding calls.
450      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
451        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
452    o pkg/seaice/seaice_lsr, a little bit of clean up
453      - rearrange some code blocks, so that now all calculations for
454        setting up the right-hand-sides done within one single block
455        (I find that easier to read and understand)
456      - rearrange freedrift-code to reduce the number of ifdefs
457      - adjust some indentations and comments
458    
459    checkpoint64z (2014/07/10)
460    o model/src and several pkgs:
461      - change argument list of all S/R called from external_forcing.F and
462        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
463        to pass, as argument, the current level tendency array to update
464        (instead of a direct update of the common bloc array).
465      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
466      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
467    o pkg/seaice/seaice_lsr.F
468      - always initialize local arrays in seaice_lsr_tridiagu/v
469      - add more local tapes to seaice_lsr_tridiagu/v
470      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
471        keep it in bi/bj loop; this seems to be essential
472      - gradients are still wrong but only by 4-7 orders of magnitude
473        instead of 15 orders of magnitude, lab_sea improves a little
474    o pkg/seaice
475      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
476        generates unnecessary code in seaice_lsr_ad
477      - add more store directives in seaice_lsr to avoid unnecessary code
478        in seaice_lsr_ad
479      - exclude some residual computations in seaice_lsr when
480        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
481        in seaice_lsr_ad
482      - add more storing, a new tape (model/src/the_main_loop.F) and
483        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
484        and klockey should be checked by a specialist)
485      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
486        and update lab_sea after previous changes in pkg/seaice below
487    o pkg/autodiff:
488      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
489        viscFacInAd : run time parameters allowing for adjoint switches
490        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
491    o pkg/ecco:
492      - introduce cost_gencost_boxmean.F that computes a box mean
493        temperature (for use in adjoint sensitivity studies).
494    o model/src/set_defaults.F : initialize viscFacAdj to 1.
495    o pkg/mom_common/mom_calc_visc.F:
496      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
497    o pkg/seaice/seaice_summary.F:
498      - statement for SEAICEadjMODE now in autodiff_readparms.F
499    o pkg/seaice:
500      - remove some store directives and add new ones in an effort to get
501        finally rid off the recomputation warnings. This is successful
502        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
503        defined (i.e. no extensive recomputation warnings left), but there
504        are still too many recomputations on the solver iteration level
505      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
506      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
507        SEAICE_SIZE.h
508      - add a store directive in S/R seaice_calc_viscosities
509    o pkg/seaice (ITD code):
510      - fix definition of Hlimit for multi-threaded case
511      - use double precision arithmetic to compute Hlimit: this affects results;
512        update output of experiment seaice_itd.
513    o replace content of verification/seaice_itd
514      - instead of a 1D column use the configuration of offline_exf_seaice
515        to test the ice thickness distribution code with ridging
516      - this is a first shot at this experiment
517      - change of some defaults of ridging parameters SEAICEhStar (from
518        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
519        and lot of new comments.
520    
521    checkpoint64y (2014/06/20)
522    o pkg/seaice/seaice_reg_ridge.F:
523      - modify the regularization of very small volumes of ice; only check
524        total volume HEFF, and do not apply correction to individual ice
525        classes because that leads to funny patterns in the heat and fw-fluxes
526        into the ocean. Adjust seaice_itd/results/output.txt
527      - replace nITD by SEAICE_multDim in loop-ranges
528    o pkg/exf:
529      - add code to process the case field period = -12. with UV interpolation.
530      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
531        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
532    o verification/global_with_exf:
533      - switch all fields period to -12. (was previously untested) in input/data.exf
534        (but keep secondary test ".yearly" unchanged); update the reference output.
535    o pkg/cal:
536      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
537    o pkg/exf:
538      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
539        to replace logical switch "exf_verbose"
540      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
541    o pkg/sbo:
542      - update from Katherine Quinn: evaluate mass directly from density and SSH
543        (budget using Finite Volume method) instead of from bottom pressure.
544      - allow testreport to collect few selected SBO output ; tested in exp.
545        global_ocean.90x40x15 (after updating the results, to include SBO output).
546      - fix some multi-threading issues (in output part).
547    o model/src & most packages:
548      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
549      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
550        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
551        "data.{pkg}" exist ; and leave the S/R (return) just after.
552      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
553        + call LAND_READPARMS from packages_readparms.F
554    o pkg/seaice:
555      - remove code that resets useThSice in S/R seaice_readparms and
556        replace it by a warning in S/R seaice_check
557      - remove parameter MULTDIM, replace with nITD and runtime
558        parameter SEAICE_multDim (still hard-wired to nITD if
559        SEAICE_ITD is defined)
560    
561    checkpoint64x (2014/05/24)
562    o verification/lab_sea:
563      - update adjoint and TLM output following changes to pkg/salt_plume
564      - un-do the update after putting back local recip_Cp in few places.
565    o pkg/salt_plume: modifications by An Nguyen:
566      - add capability to do brine rejection (salt-plume) as function of
567        volume+tracers (instead of only salinity tracer).
568      - conserve volume by exchanging volume from each kLev to above to
569        accommodate in-coming brine volume
570      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
571      - switch KPP surf buoyancy due to brine forcing to 3-d
572        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
573      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
574      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
575        in East/West Arctic.
576    o pkg/sbo:
577      - incorporate modifications from Katherine Quinn to enable the use of sbo
578        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
579        output for future testreport verification (unfinished).
580    o pkg/atm_phys:
581      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
582        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
583        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
584    o pkg/seaice
585      seaice_calc_ice_strength.F: modify expression to avoid divisions
586        (affects truncation)
587      seaice_do_ridging.F: clean up the insectarium
588      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
589      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
590      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
591      - add some debugging information and error messages (warnings)
592    o model/src: modifications relatd to atmosphere p*:
593      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
594      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
595        of vertical profile tRef in geopotential background and anomaly.
596      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
597        and pkg/atm_phys.
598      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
599        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
600    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
601    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
602        not used right now, but can be used in BGC packages to fix conservation.
603    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
604        other packages too.
605    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
606        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
607    o model/src:
608      - since we have several heat capacity (even in model/src), define "recip_Cp"
609        as local variable (no longer in common block) to avoid any confusion.
610      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
611    o pkg/exf:
612      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
613        air density as function of air Temp, Humidity and atm pressure.
614    
615    checkpoint64w (2014/05/02)
616    o verification:
617      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
618        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
619        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
620        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
621        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
622    o model/src: for atmosphere in p* coords:
623      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
624      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
625        but not yet activated.
626    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
627      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
628      - this changes the results (but not for any verification experiment, because
629        none tests this), but avoids having an extra field in the restart files
630    o pkg/seaice: remove global variable TICE (not needed)
631      - replace by TICES or local variable where necessary (cost_seaice_test,
632        seaice_diagnostics_state)
633      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
634      - use specific read/write routines for reading and writing individual leves
635        of a multilevel field
636    o pkg/ctrl & model/inc:
637      - move additional anomaly fields of control vars (related to options:
638         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
639        from DYNVARS.h into new header file: CTRL_FIELDS.h
640    o pkg/seaice: some small modifications to the ridging code
641      - make fw2ObyRidge a global variable and add the freshwater flux to
642        seaice_growth
643      - pass actual thickness from seaice_prepare_ridging, so that it is
644        computed only in one place and compute it in the same way as in
645        seaice_growth
646      - initialise more fields in seaice_do_ridging that where cause floating
647        point exceptions over land
648  o pkg/seaice: preparations for ridging code and first real ridging code  o pkg/seaice: preparations for ridging code and first real ridging code
649    - move most of "PART 1" of S/R seaice_growth into a new and separate    - move most of "PART 1" of S/R seaice_growth into a new and separate
650      S/R seaice_reg_ridge that will both regularize the state variable after      S/R seaice_reg_ridge that will both regularize the state variable after
651      advection call the actual ridging routine;      advection call the actual ridging routine;
652    - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,    - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
