4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8      => Change some of the defaults (2011/05/29):
9         - change SEAICEuseFluxForm default (from False to True)
10         - change DIFF1 default (from 0.004 m/s to 0. m/s)
11         And print warnings if DIFF1 is not set in data.seaice and centered
12          avection scheme is used without any diffusion.
13      also:
14      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
15      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
16      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
17        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
18        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
19      update results of test exp.:
20         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
21             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
22             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
23         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
24         seaice_obcs: output (SEAICEuseFluxForm=T)
25      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
26          for standard fwd & AD lab_sea tests (to keep the same output).
27    o pkg/seaice/seaice_growth.F:
28      - use Ian Fenty's capping formulas for actual ice
29      thickness thoughout EVOLUTION branch.
30      - put treatment pathological case #2) in CPP brackets
31      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
32      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
33    o pkg/seaice:
34      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
35      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
36      also pass fac as a param, which can be 1. (to update the tendency
37      field) or the time step (to update the field itself).
38      - seaice_advdiff.F: for multidim, call seaice_diffusion with
39      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
40      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
41      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
42      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
43    o pkg/seaice:
44      diffusion with centered advection scheme (diffus.F & advect.F):
45      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
46        to just compute the laplacian of input-field.
47      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
48      - fix flux-form version in diffus.F to conserve tracer.
49      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
50       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
51    
52    checkpoint62y (2011/05/26)
53    o pkg/seaice:
54     - seaice_growth.F : in EVOLUTION branch, always include
55       a_QSWbyATM_cover in qnet (as it should be).
56     - verification/global_ocean.cs32x15 : update results accordingly
57       (output.seaice.txt output_adm.seaice.txt).
58    o pkg/seaice + obcs:
59     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
60       equivalent of assuming no tracer gradient outside the OB region.
61       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
62     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
63       after changes above);
64     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
65       only at OB location (instead of over a band of OLx width).
66    o pkg/seaice:
67     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
68       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
69    o pkg/obcs:
70      - split header file "OBCS.h" into 4 separated files:
71        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
72       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
73         (contain no conditional statement which depends on OBCS options).
74      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
75        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
76    o ctrl, cost, grdchk & autodiff pkgs:
77      - make options file more standard (like other {PKG}_OPTIONS.h file but
78        with AD_CONFIG.h); clean-up some of the included header files.
79    o pkg/obcs:
80      - do not mask tracer when applying OB (tracer == 0 could generate problems)
81      - apply tracer OB values to tracer field only at OB location (instead of
82        over a band of OLx width)
83      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
84      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
85        obcs_apply_tloc.F & obcs_apply_sloc.F
86    o obcs in model/src:
87      - call OBCS_APPLY_W only if NonHydrostatic.
88      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
89      - reset dEtaHdt and wVel to zero outside OB interior region ;
90      - leave tracer unchanged outside OB interior region: This has no effect
91        on the solution but just to prevent unrealistic tracer value outside OB.
92      - zero out velocity outside OB interior region: This has no effect on
93        the solution but just to prevent unrealistic velocity outside OB.
94    o obcs and non-lin free-surf:
95       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
96       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
97       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
98       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
99       update results of test-exp. exp4(nlfs).
100    o exp4 (nlfs) test-exp:
101       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
102       with NonLin-FreeSurf); update output.nlfs.txt
103    o obcs and 2d/3d solver norm:
104       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
105       and outside OB interior region (will allow to place OB further inside the
106       domain). Depending on the domain, can affects cg2d-Norm (previous
107       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
108       and cg3d-Norm (previous Norm was computed before canceling OB terms),
109       e.g. in tutorial_plume_on_slope.
110      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
111    o pkg rbcs:
112      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
113      - add capability to apply relaxation to horizontal velocity uVel & vVel.
114    o pkg/grdchk: add gradient check for control variable xx_shifwflx
115    o pkg/shelfice/shelfice_init_fixed.F
116      fix CPP-flag combinations
117    o pkg/seaice: Merge iceage code of Pierre Rampal
118      * update/change/correct ice age calculations
119      * add age updates for pathological cases
120      Probably needs more testing...
121    
122    checkpoint62x (2011/05/13)
123    o pkg/mom_vecinv:
124       high-order vorticity scheme: use interior masks (maskInW & S)
125       to zero-out (outside OB) gradient of vorticity.
126    o verification exp.:
127       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
128       hs94.128x64x5 and seaice_obcs ; update results.
129    o pkg/obcs:
130      fix bug in OBeta for YZ sections in obcs_exf_load.F
131    o pkg/ctrl, pkg/shelfice, and optim:
132      - add new control variable xx_shifwflx (fresh water flux underneath ice
133        shelves). This is almost as tedious as obcs-ctrl, because the
134        variables needs its own mask.
135      - add a cost function term that penalizes the deviation of xx_shifwflx
136        from the first guess (zero) in analogy to other control variables
137    o pkg/shelfice:
138      - start basic adjoint
139    o pkg/ctrl:
140      - remove extra 2D field "for good measure" when initializing in
141        ctrl_set_globfld_[xy/xz/yz].F
142      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
143      - improve error messages in ctrl_set_unpack_*
144    o OBC implementation in momentum:
145       use interior masks (maskInC,W & S) in momentum S/R:
146       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
147       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
148       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
149       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
150       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
151        (and also with Leith/Smagorinsky harmonic-viscosity).
152       Update output of experiment dome and exp4 (+nlfs).
153    o exp4 test-exp:
154      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
155        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
156        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
157        time-varying OB at Western-side for wVel (NonHyd); update output.
158      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
159        and biharmonic-viscosity ; also use prescribed time varying OB.
160    o pkg/obcs:
161      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
162    o model/src:
163      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
164      - initialise startTime & nIter0 with unlikely values: allows to set one
165        from the other without ambiguity.
166    o seaice_obcs test-exp.:
167      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
168    o pkg/obcs:
169      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
170        no longer needed with maskInC,W,S in pkg/generic_advdiff.
171    o pkg/seaice:
172      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
173        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
174      - fixed bug in the initialization of sea ice salinity variable HSALT
175        in seaice_init_varia.F  (removed dependence on ICE2WATR)
176    o fizhi-cs test exp.:
177       switch reference output convention for these 2 non-standard test-exp,
178        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
179          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
180       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
181    o model/inc:
182      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
183        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
184    o pkg/seaice:
185      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
186    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
187      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
188        and initial HSALT
189    
190    checkpoint62w (2011/04/26)
191    o pkg/mom_fluxform:
192      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
193      - use parameter "sideDragFactor" in no-slip BC side-drag part.
194      - update output of exp. global_ocean.90x40x15
195    o pkg/mom_vecinv:
196      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
197    o update seaice exp.:
198      use more consistent parameter values (remove "backward compatability only":
199       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
200      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
201       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
202    o update test-exp global_ocean.90x40x15:
203      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
204      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
205      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
206      o turn on zStar & viscA4 in standard set-up (dir input/)
207        and update output files: output.txt & output.dwnslp.txt
208    o new AD-test experiment: obcs_ctrl
209      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
210    o pkg/dic:
211      fix two bugs in handling water vapour pressure in carbonate chemistry
212      and air-sea fluxes. Found by Val Bennington and Galen McKinley
213      (add DIC Option = WATERVAP_BUG to recover old results)
214      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
215    o adding allowInteriorFreezing option to check for water below freezing point
216      at depth and bring the negative heat anomaly to the surface level
217    o pkgs _fields_load:
218      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
219      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
220        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
221        rbcs to get interpolation weights and time reccord number.
222      - fix multi-threading in aim_fields_load.F
223      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
224    o external_fields_load:
225      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
226       interpolation weights) to use in a periodic time-series ; do not divide by
227       time-step to convert to integer:
228       - this fixes case where externForcingPeriod is not multiple of time-step
229          (Thanks to Christopher L. Wolfe)
230       - this fixes case where externForcingPeriod is an odd multiple of time-step
231         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
232      store index of time-record which is currently loaded:
233       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
234       - needed for the adjoint but not yet used because of extensive recomputations;
235         (to be fixed soon)
236    
237    checkpoint62v (2011/04/02)
238    o verification/1D_ocean_ice_column added to test Ian Fenty's
239      pkg/seaice_growth.F modifications for improving sea ice code differentiability
240    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
241      (new velocity statistics after changing maskInW & maskInS definition)
242    o pkg/generic_advdiff with OBCS:
243      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
244      equivalent to assumption of no tracer gradient outside the OB region.
245      This will affect the results if using obcs+biharmonic diffusion.
246      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
247    o pkg/obcs:
248      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
249      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
250      in Interior region. No impact on solution but affects Velocity monitor stats.
251    o pkg/ptracers (adjoint)
252      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
253      tape file for each tracer
254    o model/inc/src and pkg/autodiff: add parameters that allow to turn
255      of parts of the adjoint code at run time. For now, there are only
256      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
257      parameters are set in data.pkg.
258      This is the lazy coward's version of doing this, but still useful for
259      debugging. In order to do it right, everything needs to be moved to
260      pkg/autodiff.
261    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
262      the end; this fixes the adjoint balancing code for open boundaries.
263    o pkg/ctrl:
264      - change behavior of xx_${varname}period to be analogous to exf-conventions:
265        xx_${varname}period =   0.,  means time-independent control part
266        xx_${varname}period = -12., means one-year-periodic monthly control part
267      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
268        clean up ctrl_init a little, remove unused variables
269      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
270      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
271    
272    checkpoint62u (2011/03/15)
273    o model/src:
274      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
275        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
276      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
277        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
278    o pkg/ctrl/obcs/ecco:
279      - remove obsolete, unused, and partially broken code:
280        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
281        ALLOW_CTRL_OBCS_BALANCE
282      - put a stop statement into ecco/cost_obcsvol.F, but also add
283        cost_obcsvol to ecco_ad_diff.list
284    o pkg/ecco: fix counting cost function contributions for obcs (code
285      by Matt M.) and diffkr for diagnostics
286    o pkg/ecco, pkg/ctrl, pkg/grdchk:
287      add cost penalty terms for initial uvel, vvel, eta controls
288      and I/O for prior error files
289    o pkg/mdsio:
290       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
291       (new argument) to check for tiled file in mdsioLocalDir : this fix the
292       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
293    o pkg/ctrl:
294     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
295       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
296       unused and superfluous variables
297     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
298    o pkg/ecco
299     - enable adjoint of Stevens OB
300    o pkg/ctrl/ecco/grdchk:
301      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
302        Fortunately, we do not have any tests for the numerous cpp-flagged
303        option of "obcs as control parameters" so we will never know
304        if this is an improvement (but at least now things compile).
305      - remove an obsolete initialization from ecco_cost_init_barfiles.F
306      - fix some problems within never used ifdefs to make the code compile
307    o pkg/obcs:
308     - Refine Interior mask definition to work with more complex OB (e.g.
309       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
310       read in Interior mask from file. Check if Interior mask is consistent
311       with OB list of indices.
312    o pkg/seaice
313     - beginning code for a seaice tracer package,
314       but currently only used for seaice age: SEAICE_AGE
315       SEAICE_num = 4
316       iTracer = 1: area-weighted ice age
317               = 2: volume-weighted ice age
318               = 3, 4: template for one-year vs. multi-year ice
319       data.seaice has new namelist SEAICE_PARM03 for arrays related to
320       SEAICE_num
321    
322    checkpoint62t (2011/03/05)
323    o pkg/obcs:
324     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
325       then normal component. This ensures that the normal component is set
326       correctly even when it conficts with tangential setting from an other OB.
327       Affects results of test-experiment seaice_obcs: update the output.txt
328    o pkg/obcs:
329     - add code to monitor statistics of dynamical fields at OB.
330     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
331       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
332       - change default: balance the Net inflow through all OB (instead of balancing
333         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
334     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
335       to match Nortern OB inflow (OBCS_balanceFacN=0).
336    o pkg/seaice:
337     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
338    o pkg/seaice (seaice_growth v 1.113):
339     - reverting seaice_growth to v 1.111 in order to have code with exact bit
340       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
341       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
342       runtime flag SEAICEareaFormula is kept but is inactive
343    o model/src:
344     - add new param to scale curvilinear grid distance and area when using
345       a different sphere radius from the grid-files.
346     - test/check multi-threads EXCH applied to local variable (cg2d_x)
347    o adjoint:
348     - enable adjoint of Stevens OB
349     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
350       (a bit delicate because of potentially modified adj. common block structure;
351       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)

354    o pkg/seaice (seaice_growth v 1.112):
355     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
356       computing the ice cover tendency from effective thickness tendencies. Include
357       Ian Fenty's formula.
358     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
359       SEAICEareaFormula.
360     - simplify notations for the various d_HEFF/d_AREA terms.
