4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/obcs:
8      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
9    o pkg/dic & seaice:
10      - fix compilation of ocean component for coupled atm+ocn model with
11        seaice dynamics & dic.
12    
13    checkpoint65x (2016/06/11)
14    o add a license text file in main MITgcm tree.
15    o added pkg/bling:
16      - intermediate complexity biogeochemical model
17      - see bling_description.txt for details
18      - verification experiment is global_oce_biogeo_bling (for now, in
19        Contrib/verification_other/); tested daily on baudelaire with gfortran.
20      - add entry point in pkg/gchem for new pkg "bling".
21    o pkg/seaice: fix tensile stength computation
22      - replace global field tensileStrength by tensileStrFac
23      - tensileStrFac can be computed once in S/R seaice_init_varia
24      - fortunately that does not affect any verification results
25    
26    checkpoint65w (2016/05/12)
27    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
28         with ECCO_CTRL_DEPRECATED defined
29    o verification/global_ocean.cs32x15:
30      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
31        with "selectNHfreeSurf=1".
32    o model/src (non-hydrostatic free-surface):
33      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
34        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
35      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
36        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
37        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
38        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
39      - Update output (changes at machine truncation level) of verification exp:
40        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
41        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
42    o pkg/seaice: ITD code
43      - fix picking up from a single category model by initialising
44        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
45      - split a long warning message in seaice_check_pickup.F into two lines,
46        because NEC SX-ACE cannot deal with the long line.
47    o model/src:
48      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
49    o pkg/seaice:
50      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
51    o pkg/seaice:
52      - add basal stress as parameterisation for grounding ice
53        following Lemieux et al. (2015)
54      - turn on by setting new parameter SEAICEbasalDragK2 to a value
55        larger than 0. Lemieux et al. (2015) recommend 15.
56      - The adjoint complains with extra recomputations so there is also a
57        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
58        order to postpone the problem
59      - compile the new code in lab_sea
60    o verification/halfpipe_streamice:
61      - update both TAF and OpenAD adm output (machine truncation differences)
62    
63    checkpoint65v (2016/04/08)
64    o verification/advect_xz:
65      - increase overlap size from 3 to 4 and add new secondary test for PQM
66        advection scheme (with mono & wino limiter).
67      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
68    o model/src:
69      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
70        added phi0Ref) to set vertical axis origin and phiRef origin;
71        keep Ro_SeaLevel for backward compatibility (with a warning).
72       According to coordinate and fluid type:
73        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
74        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
75        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
76        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
77      - remove Ro_SeaLevel from ATM experiment parameter files;
78      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
79        complement; update output.txt (changes at machine truncation level).
80    o pkg/seaice/seaice_evp.F
81      - simplify computation of deltaZ and zetaZ to simple averaging following
82        Bouillon et al. (2013). This removes a lot of code, but also changes
83        verification experiment lab_sea.hb87 -> updated
84    
85    checkpoint65u (2016/03/14)
86    o pkg/generic_advdiff:
87      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
88        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
89        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
90        testing and not for actual use.
91    o model/src:
92      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
93        origin r = rF(1);
94      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
95        in EOS for height coordinate: enable to include NH Pressure or to use
96        more accurate pressure vertical profile; options not linked to EOS type
97        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
98      - start to implement variable gravity (along vertical): for now, only with
99        z-coords (not even z*).
100      - add Ideal Gas equation of state for height coordinate.
101      - update OpenAD output (affected at machine truncation level) of exp:
102        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
103    o pkg/exf:
104      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
105        of exf interpolation (before any rescaling, rotation or interpolation
106        to velocity point) for each field that gets loaded from file. This option
107        identically mimics the input file organization (e.g. record numbers in year
108        by year input files) besides the change in horizontal grid.
109      - add rotateStressOnAgrid run-time switch so that wind stress fields
110        can be provided on the A-grid in zonal/meridional direction and
111        rotated on the fly. This only applies to the case when the exf
112        interpolation is off and rotateStressOnAgrid is false by default.
113    o model/src:
114      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
115        it's also used with pkg/atm_phys) and add few more parameters (but still
116        inactive, src code yet to come)
117    
118    checkpoint65t (2016/02/10)
119    o pkg/atm_phys:
120      - from Ruth Geen: add optical depth dependence on CO2 concentration.
121    o model/src:
122      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
123        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
124        Update output of exp. deep_anelastic (changes at truncation level).
125    o tools:
126      - add a hack in "remove_comments_sed" (used only with TAF) for recent
127        version of OpenMPI (shipped with FC.23): comment out the new header
128        file "mpif-sizeof.h" which causes problems to TAF.
129    o pkg/seaice:
130      - change the termination criterion so that maxits (SEAICElinearIterMax)
131        has an effect
132      - unify iteration parameters for implicit solvers (JFNK and Picard)
133        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
134        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
135        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
136        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
137        SEAICEnonLinTol     replaces JFNKgamma_nonlin
138      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
139      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
140        use with SEAICEuseKrylov
141    o pkg/seaice/seaice_lsr.F
142        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
143        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
144        an effect.
145    o pkg/seaice: add two new parameters
146      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
147        parameter is not in any namelist)
148      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
149        a preconditioner for the non-linear Newton iteration of the JFNK
150        solver
151    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
152      affects some experiments at truncation level:
153      - global_ocean.cs32x15.icedyn (11 digits),
154      - global_ocean.cs32x15.seaice (11 digits),
155      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
156      - also update global_ocean.cs32x15 adjoint and tangent-linear results
157    o pkg/salt_plume & pkg/thsice:
158      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
159        connect salt_plume flux to ATM-OCN coupling pkgs interface:
160       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
161         export to coupler interface) even without compiling pkg/salt_plume ;
162       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
163         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
164    o pkg/dic:
165      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
166        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
167        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
168      - move also update with values from ATM-OCN Coupler in the same new S/R
169        (previously done in ocn_apply_import.F).
170    o tools/adjoint_options:
171      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
172        has been changed on Jan 14, 2016.
173    o pkg/ggl90:
174      - add alternative discretisation of vertical shear (off by default), to
175        compute the mean (@ grid-cell center) of vertical shear compon instead of
176        vertical shear of mean flow (@ grid-cell center).
177      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
178        results on adjacent faces of cubed-sphere grids; this fix the restart.
179    o pkg/atm_compon_interf:
180      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
181        pass last value, stored directly before export to CPL ;
182        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
183      - remove atmSLPr from pickup files (no longer needed for restart)
184    
185    checkpoint65s (2016/01/13)
186    o eesupp & genmake2:
187       - first check for Function ETIME and, if it fails, then check for subroutine
188         ETIME and consistent output; use the appropriate version in timers.F
189    o model/src:
190      - to check restart test, add option to apply EXCH to U,V earlier, just before
191        integr_continuity; turned off by default.
192    o pkg/dic:
193      - remove CPP option USE_ATMOSCO2 (not needed)
194    o tools/tst_2+2:
195      - try to ignore difference between +0 and -0 in binary file, causing test
196        to fail for no good reason.
197    o eesupp & genmake2:
198      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
199        but also check (in genmake2) that test runs and returns meaningful results.
200    o coupler pkgs:
201      Finish implementation of optionally-exchanged variable switches (started on
202       Nov 12) with addition of few more exchanged fields, including 2-way exchange
203       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
204       advection in OCN component; this requires sequential coupling.
205      coupler (pkg/atm_ocn_coupler):
206      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
207        routines (useful for debug).
208      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
209         flux, DIC fields) if corresponding switch is ON.
210      - add option to export RunOff to OCN (to use for DIC river input)
211      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
212      components (pkg/atm_ & ocn_compon_interf):
213      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
214        optionally exchanged fields; add a check & stop in cpl_readparms.F.
215        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
216        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
217      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
218        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
219      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
220      - hold in common block coupler optionally-exchanged variable switch
221        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
222      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
223        this is intended to replace the OCN cplFldtave.* output files (not updated
224        to contain new additional exchanged fields).
225    o pkg/dic:
226      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
227    o pkg/thsice:
228      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
229        and writing of thsice pickup files.
230    o pkg/atm_compon_interf:
231      - move all field individual export-call out of cpl_export_import_data.F
232        into new S/R ATM_EXPORT_FIELDS
233    o pkg/atm_compon_interf:
234      - store state variables (for now, only thSIce fields) just before beeing
235        exported (in cpl_export_import_data.F, like on ocean side) instead of from
236        atm_store_my_data.F like all exported fluxes.
237      - new version of pickup_cpl: write field names into meta file and read meta
238        file to find field postion in pickup. Also only write/read fields meeded for
239        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
240    o pkg/dic:
241      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
242    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
243        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
244        value can be from domain [0,1] to average between the two methods
245    o pkg/atm_phys:
246      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
247        hold fixed in time).
248    
249    checkpoint65r (2015/12/21)
250    o pkg/seaice:
251        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
252        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
253    o pkg/seaice:
254      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
255        when SEAICEscaleSurfStress=.TRUE.,
256      - apply areaW and areaS in S/R seaice_calc_lhs
257    o pkg/atm_phys:
258      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
259        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
260        for individual contribution (convection, LSC cond, radiation)
261      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
262        information); activated with: solar_exponent=0. and wv_exponent=-1.
263    o pkg/ggl90:
264      - within IDEMIX add upper limit for horizontal group velocity to
265        avoid instability problems in the explicit horizontal diffusion term for
266        long time steps or high resolution
267    o pkg/diagnostics:
268      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
269        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
270    o testreport:
271      - remove "-v" (verbose option) in default mpirun command.
272    o pkg/seaice/seaice_growth:
273      - catch potential division by zero in ITD code, does not change
274        verification results
275    o pkg/ecco:
276      - retire old codes to the Attic. The calls to retired functions are
277        left in a commented form in case they ever need to be re-activated.
278      - ecco_check.F: issue warning if any old CPP option is
279        defined that corresponds to retired codes -- then stop.
280    o pkg/atm_compon_interf:
281      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
282        coupler: use last time-step value instead of average over cplSendFrq_iter
283        time-step, similar to what is done for seaIceMass.
284        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
285    o eesupp & genmake2:
286      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
287        <= remove until a fix is found for some ifort version on ia32 machine.
288    o pkg/seaice/seaice_evp:
289      - refine residual computation
290    
291    checkpoint65q (2015/11/18)
292    o pkg/seaice/seaice_evp:
293      - fix residual computations so that they no longer affect the actual
294        simulation code
295      - fix seaice_readparams to be able to actually set new parameters
296        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
297    o model/src:
298      - fix wrong truncation (single prec) from "FLOAT" function in expressions
299        like: deltaT*FLOAT(myIter) when myIter is large:
300         a) replaced by DFLOAT (if not seen by TAF);
301         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
302    o pkg/aim_v23:
303      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
304        when pickupSuff is set ; do write rolling pickups + at the end of the run.
305    o pkg/atm_ocn_coupler + ocn_compon_interf:
306      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
307        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
308        add corresponding call in DO_OCEANIC_PHYS.
309    o coupler pkgs:
310      Start a new way to set-up optionally-exchanged variables (previously, only
311       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
312       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
313       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
314       compononent param default can be set accordingly).
315      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
316       but rather applies to a group a fields (going both ways like for DIC)
317       and corresponds to an option of coupling config.
318      coupler (pkg/atm_ocn_coupler):
319      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
320        and read namelist directly (without eessup S/R calls) instead of
321        in the very un-flexible old way, 1 param per line, in fixed order;
322      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
323        cleanly in CPL_CHECK_CPLCONFIG
324      - add new coupling-exchange selectors (some not yet active) including
325        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
326                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
327      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
328        component ; called directly from coupler.F, after comp. registrations;
329      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
330         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
331          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
332      components (pkg/atm_ & ocn_compon_interf):
333      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
334        CPP header file in all pkg source files.
335      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
336        ATM/OCN_CHECK_CPLCONFIG;
337      - add error-counter to track errors (e.g., in "data.cpl") and to stop
338        cleanly in ATM/OCN_CHECK_CPLCONFIG;
339      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
340        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
341        before PACKAGES_READPARMS;
342      verification/cpl_aim+ocn/:
343      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
344        "data.cpl" for coupler (in input_cpl).
345    o eesupp/inc:
346      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
347        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
348        to always cumulate tile local-sum in the same order (still uses
349        MPI_Allreduce like standard code).
350      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
351        that are now identical to standard version (in eesupp/inc).
352    o pkg/shelfice:
353      - add SHELFICETransCoeffTFile for initializing spatially varying
354        heat and salt transfer coefficients
355    o pkg/atm_compon_interf & ocn_compon_interf:
356      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
357        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
358      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
359    o pkg/atm_ocn_coupler:
360      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
361    o pkg/rbcs:
362      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
363        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
364      - add a short report (to STDOUT) about RBCS-mask settings.
365    
366    checkpoint65p (2015/10/23)
367    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
368        there is no adjoint test for EVP, we don't know what it does to the adjoint
369        solution, but at least there are no more recomputation warnings left
370    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
371        a chance of giving the same results as a fully converged VP (JFNK) solver
372    o tools/adjoint_options/adjoint_diva:
373      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
374    o pkg/streamice:
375      - spotted bug in streamice_driving_stress using dyG where should have been dxG
376    o pkg/exf:
377      - remove STOP statement that prevented to use wind or (wind-)stress
378        interpolation for constant-in-time forcing fields (wind/stress period = 0).
379    o pkg/seaice:
380      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
381        5 additionals 2D fields and 6 new store directives
382      - change logic in seaice_readparms.F: EVP code can now be turned on in
383        various ways, setting SEAICE_deltaTev is no longer required,
384        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
385        or SEAICEaEVPcoeff
386    o pkg/shelfice/shelfice_thermodynamics.F
387      - redefining uLoc/vLoc to u/v, instead of 2u/v
388    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
389      - this is an intermediate state of a truely converging EVP that has
390        the potential of outperforming implicit VP methods, I do not recommend
391        using it yet.
392      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
393        and all parameters are hardwired
394      - for convergence it still requires very smooth regularisations, that means,
395        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
396        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
397        specific averaging appears to be required, still subject to tuning
398      - still needs cleaning and I need to turn parameter into runtime parameters
399      - add code to compute and print residuals of iteration, compile with
400        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
401    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
402      that entered with r1.54 on Sep04, 2015, -> update results
403    
404    checkpoint65o (2015/09/14)
405    o pkg/mom_vecinv & mom_common:
406      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
407        called from there.
408      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
409        allows to use Vector-Invariant form in deep atmos and anelastic formulation
410    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
411      and Koenig-Beatty+Holland (2012)
412      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
413      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
414      - requires an extra input argument for S/R seaice_calc_viscosities
415      - tensileStrength's depth dependence is different from Itkin et al. (2015)
416        (to be changed and played with, for now exponential)
417    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
418      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
419        by AREA according to Connelly et al. (2004), JPO.
420      - For EVP and the LSR solver, the implicit part of the drag term is
421        the only non-zero term in the denominator when there is no ice (which
422        prevented running the model with zero ice-ocean drag). If
423        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
424        (or zero main diagonals BU/BV) which need to be caught. A practical
425        consequence is that for open water, the momentum equation reduce
426        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
427        they happen to be zero, often leading to a non-zero solution over
428        open water.
429    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
430        efficient EVP method.
431      - introduce area-weighted averages for e12 (analogously to
432        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
433        remain, but also changing the order of terms in the previous average
434        changed the results as much) -> update experiment
435      - add SEAICE_DELTA_SMOOTHREG code
436      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
437        TEM-code
438      - adjust loop bounds so that only required fields are computed
439      - add new averaging code for zetaZ/deltaZ (again similar to
440        seaice_calc_viscosities.F), inactive by default for now (will change
441        results again), but will replace old code eventually
442    o eesupp/src:
443      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
444        to always cumulate tile local-sum in the same order
445        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
446        Still uses MPI_Allreduce (like standard code) but on array of tiles
447        and should be faster than GLOBAL_SUM_SEND_RECV code.
448      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
449        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
450      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
451         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
452         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
453         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
454         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
455    
456    checkpoint65n (2015/07/29)
457    o pkg/thsice:
458      - add a warning when used with pkg/aim but without updating SST
459        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
460    o pkg/offline:
461      - change where Offline-Fields are loaded, from load_fields_driver.F to
462        directly within FORWARD_STEP, just after updating iter number and time;
463      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
464        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
465       These changes allow:
466        a) to recover exactly on-line results using deltaToffline=deltaTClock,
467        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
468        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
469        time-step, both with GM & KPP files and with recomputing these fields;
470        b) no needs to switch on staggerTimeStep anymore;
471        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
472      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
473    o pkg/offline:
474      - change (rarely used) offset-iteration parameter to an offset time (in s):
475        can easily recover previous offset-iter effect by setting offset-time
476        (offlineTimeOffset) to offset-iter x deltaToffline;
477      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
478        in KPP as part of surface buoyancy forcing) in offline run.
479      - fix ptracers KPP non-local term in the case where KPP is re-computed.
480    o OpenAD
481      - Adding preliminary ggl90 test to OpenAD verification.
482        Config. with ggl90 currently diverges after 64 time steps
483        so will need more work to become more stable
484      - Adding preliminary kpp test to OpenAD verification.
485        required small tweakes in kpp_routines.F
486      - Merge and update from Krishna Narayanan's contrib area:
487        * Add one variable for preliminary OpenAD DIVA
488        * Add replacement time-stepping for OpenAD DIVA
489        * genmake2 flag -diva (but only for OpenAD; preliminary)
490        * required modifs for OAD_support
491        successful preliminary test for tutorial_global_oce_biogeo/
492    o pkg/seaice:
493      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
494      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
495        delta with a smooth function in s/r seaice_calc_viscosity
496        (no effect on EVP)
497      - rename local suffix "sqr" into "sq" for more consistent variable names
498    o pkg/seaice:
499        add new parameter SEAICE_deltaMin that is used ***only***
500        for regularizing Delta (and nothing else, like the parameter
501        which is also used for all sorts of things SEAICE_EPS).
502        Defaults to SEAICE_EPS for backward compatibility only.
503    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
504        the wrong key by inialising it before use -> fixes a recomputation
505        problem but does not fix the gradient
506    o pkg/layers:
507      - move resetting of flux arrays to outside the iLa loop
508        (this caused layers_diapycnal to not work with more than one layer coord.)
509      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
510    o pkg/layers:
511      - remove from common block 3D layers fields (used to diagnose transport
512        in tracer coords) and declare them as local arrays in layers_calc.F
513    o pkg/seaice:
514      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
515        in lab_sea forward experiment (changes results -> updated)
516      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
517    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
518       computations; for SEAICE_VECTORIZE_LSR
519      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
520        sweep to the outside,
521      - remove store directives and add "CADJ loop sequential" directives
522        in analogy to model/src/solve_tridiagonal.F
523      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
524        boundaries to yield more readable code. This has also the charming side
525        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
526        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
527        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
528        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
529        an additional option)
530       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
531       but the adjoint gradients (which are affected by this change) still explode.
532    o coupler (atm & ocn _compon_interf):
533      - avoid using Exch2 IO mapping if not suitable.
534    
535    checkpoint65m (2015/06/15)
536    o pkg/layers:
537      - clean-up old parameters setting (from Sep 2012):
538        + remove old parameters setting from common block (declared locally);
539        + stop if any old parameter is mixed with new parameters;
540        + check for valid or consistent parameter setting (e.g., layers_name)
541      - check that layers_bounds for Pot.Density are in the right range;
542        this is supposed to catch un-updated setting after recently shifting
543        potential density field "prho" by -1000 (now in "sigma" scale).
544    o pkg/layers:
545      - Added missing call to layers_fill for keeping track of tottend in
546        pkg/diagnostics/diagnostics_fill_state.F
547    o pkg/layers:
548      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
549        of diapycnal fluxes
550    o pkg/layers:
551      - reverted changes to interpolation to previous treatment; there
552        was never actually a problem
553    o pkg/layers:
554      - fix interpolation of layers tracers in the presence of partial cells
555      - add lots of new functionality to compute water mass transformation
556        (enabled by CPP flag LAYERS_THERMODYNAMICS)
557      - add new calls from main code (diags_oceanic_surf_flux.F,
558        thermodynamics.F, impldiff.F) and gad to save the necessary fields
559        for layers_thermodynamics calculations
560    o pkg/ptracers:
561      - add capability of stepping a passive tracer forward without advection
562        by setting PTRACERS_advScheme to 0.
563    o pkg/diagnostics:
564      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
565    o pkg/layers:
566      - shift potential density field "prho" by -1000 for density layer averaging so
567        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
568        Note that density bin boundaries (layers_bounds in data.layers) have
569        to be set accordingly (i.e., shifted, in sigma scale).
570    o pkg/layers:
571      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
572      - fix calculation of layer non-weighted velocity and layer probability
573      - add diagnostics for pot.density used for layer averaging
574    o pkg/seaice:
575      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
576        positiveness, modify a few comments and improve variable names,
577      - the changed computation of deltaC affects most seaice-related
578        experiments at the truncation level.
579        seaice_itd.thermo is affected by far the most, with
580        only 7 digits of agreement remaining; update experiments.
581    
582    checkpoint65l (2015/05/04)
583    o pkg/shelfice:
584      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
585        factor drKp1 to zero where it is negative (ie. do not use
586        SHELFICEBoundaryLayer if hFacC>1)
587      - the same for factor drLoc in shelfice_forcing.F
588    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
589        with modules in ptracers, when using testreport option "-small_f"
590    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
591      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
592    o verification/testreport
593      - add new option -small_f
594        with this option testreport first makes the target small_f (*.f files)
595        before running make (all). This is useful for explicit inlining when
596        all sources need to be full available.
597    o pkg/exf/exf_interp.F:
598        remove previous changes related to reverse (decreasing) input grids latitude
599    
600    checkpoint65k (2015/04/01)
601    o pkg/ecco:
602        fix missing cosphi initialization; use eccoiter in place of optimcycle;
603        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
604        instead of active read/write
605    o pkg/ctrl:
606        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
607        instead of active read/write.
608    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
609        return if .NOT.useAUTODIFF
610    o pkg/seaice: add CPP brackets (cost function related).
611    o model/src:
612        add useAUTODIFF run time switch.
613    o pkg/exf/exf_interp.F:
614        add code to allow input grids with latitude starting in the north (i.e. when
615        j=1 corresponds to northern edge of field); modify global_with_exf to test
616        this feature.
617    o verification/testreport:
618      - replace "grep -A3" with POSIX conformal sed command, because there are
619        implementations of grep that cannot do contextual searches
620      - replace "cat -n" by "nl" (two occurrences), because not all implementations
621        of "cat" have the option "-n"
622    o model/src:
623        add new file gsw_teos10.F that contains 3 functions, more or less a copy
624        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
625        convert from conservative to potential temperature. For now they are not
626        called anywhere.
627    o pkg/ggl90: make "useIDEMIX" useful
628      - re-organize code in s/r ggl90_calc a little to move computations that
629        are different for idemix into separate loops (changes verification
630        experiment idemix at truncation level, 12 digits remain -> updated)
631      - requires 2 new 2D fields KappaM, verticalShear
632      - make hFacI and recip_hFacI local 3D variables that are passed to
633        s/r ggl90_idemix
634      - fix and improve some comments
635    
636    checkpoint65j (2015/02/25)
637    o pkg/openad
638      - synchronize seawater.F with version in model/src: replace routine
639        body of sw_temp by calling sw_ptmp and fix/add a few comments.
640    o pkg/mnc:
641      - change default value of pickup_read/write_mnc params to FALSE
642        (since few features are missing in reading MNC pickup files).
643    o model/src:
644      - change default (background) vertical diffusivity for salt to be the
645        temperature (background) vertical diffusivity.
646      - change background vertical diffusivity in vertical mixing pkgs ggl90,
647        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
648        This makes ptracers default diffusivity (that uses salt diffKr) more
649        consistent with vertical mixing schemes.
650    o verification/testreport:
651      - fix typo in "-pcls" option ;
652      - put temp files in /tmp (instead of in local dir)
653      - add option "-ncad" to use genmake2 new option "-nocat4ad"
654      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
655    o pkg/ggl90 (idemix code):
656      - apply few fixes ; add some missing "_d 0" ; update output of exp.
657        global_ocean.90x40x15.idemix
658    o OpenAD
659      - enable active file I/O and begin removal of work-around code
660        for OpenAD for handling control variables (memory vs. active files)
661      - new CPP options file OPENAD_OPTIONS.h
662      - revert to genarr2d gradient check for hs94.1x64x5
663      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
664      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
665    o tools/genmake2:
666      - add option for an alternative Makefile (from Martin) where multiple
667        source files are sent to TAF (instead of all in one file).
668    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
669      - code provided by Carsten Eden as an extension of ggl90
670      - so far the code is turned on within ggl90 by setting a CPP-flag at
671        compile time; a runtime flag implementation is not yet complete
672      - tested in new verification experiment global_ocean.90x40x15.idemix
673    o verification:
674      - reduce length of the AD test run by half for experiments
675        global_ocean.cs32x15 (std + thsice) and isomip
676      - enable active file I/O for OpenAD, adjust verifications accordingly
677      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
678    o verification/testreport:
679      - fix two non-POSIX sed statements so that there are no error messages
680        on Mac OS X
681      - replace hostname -s with hostname | sed 's/\..*$//'
682    o model/src/seawater.F:
683      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
684        (following the matlab code), which would have avoided the bug caught
685        by Matt (see below) in the first place
686    o pkg/shelfice:
687      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
688        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
689      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
690        ice-shelf case (i.e., within surface level).
691      - add config summary in shelfice_check.F
692      - remove global variable recip_SHELFICElatentHeat and replace by a local
693        variable recip_latentHeat
694      - introduce diagnostics for friction velocity uStar (in case of
695        SHELFICEuseGammaFrict)
696      - change verification experiment isomip.htd:
697        + start from pickup (as input_ad at nIter0=8640)
698        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
699        + test SHELFICEuseGammaFrict = .TRUE.
700        + test SHELFICEadvDiffHeatFlux = .TRUE.
701    o model/src:
702      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
703        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
704        update output of experiments global_with_exf.yearly and isomip (all 6).
705    o pkg/shelfice:
706      - change setting of kTopC to also be zero where there is no ice-shelf.
707      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
708        ice-shelf is.
709      - first attempt to get RealFreshWaterFlux effects: for now, only without
710        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
711    o pkg/seaice: add the option to prescribe a fixed thickness PDF
712      for thermodynamic calculations
713      - because of divisions of the type 7/7 not exactly equal to 1, this change
714        affects results of some verification experiments by up to 4 digits:
715        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
716        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
717        adjoint: lab_sea, lab_sea.noseaicedyn
718        -> updated
719    
720    checkpoint65i (2015/01/23)
721    o model/src:
722      - change units of frictionHeating field from W to W/m^2
723      - fix bug in frictional heating from stratospheric drag in
724        S/R ATM_PHYS_TENDENCY_APPLY_V
725      - with synchronous time-stepping: move resetting to zero of frictionHeating
726        field from load_fields_driver.F to thermodynamics.F ;
727      - add diagnostics for frictional heating.
728    o model/src & gmredi K3D:
729      - add frictionHeating field to pickup-files (for synchronous time-stepping)
730      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
731      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
732        and name in pickup file).
733      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
734    o model/src:
735      - move (from ini_forcing.F) initialisation of all arrays in header file
736        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
737        (since Nov 2012) with option selectAddFluid=1.
738    o pkg/shelfice:
739      - change units (+ document) of newly added field "shelfIceMassDynTendency"
740      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
741    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
742    o pkg/seaice: two new runtime parameters:
743      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
744        long overdue
745      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
746        parameterization of tensil stress for fast ice (does not do anything yet)
747    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
748        for LSR: move checking overlaps out of JFNK-if-block
749    o pkg/atm_phys:
750      - move copy of grid and dynamical fields out of atm_phys_driver.F into
751        new S/R ATM_PHYS_DYN2PHYS.
752      - fix level height for Linear Free-Surf case (to be consistent with
753        fixed-in-time pressure levels).
754    o pkg/mom_common (bottomdrag):
755      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
756        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
757        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
758    o pkg/shelfice (u/v_drag):
759      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
760      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
761        (now similar to shelfice_u_drag.F)
762      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
763        from mom_vecinv.F (similar to mom_fluxform calls).
764    o pkg/mom_common (bottomdrag):
765      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
766      - add options for alternative discretisation of velocity norm in quadratic
767        bottom drag: averaging of grid-cell-center KE to U.point and V.point
768        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
769        improves when averaging only the other component (e.g. vVel for U bottom
770        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
771      - add options (bottomVisc_pCell) to account for partial-cell in bottom
772        friction (no-slip BC) thus getting the true distance from the bottom;
773        off by default since this also reduces model stability (explicit bottom
774        friction). Changes produce different machine truncation with linear-drag
775        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
776        front_relax (bvp & mxl, 10 & 11 digits).
777    o model/src & mom pkgs:
778      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
779        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
780      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
781        just copy level Nr value to level Nr+1.
782    o doc:
783      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
784    o pkg/shelfice:
785      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
786        SHELFICE.h: move array shelficemass to init_varia, initialise
787        from array shelficemassinit, which is set in init_fixed and
788        has option to be set from file; introduce array
789        shelficeMassDynTend array, set thru file in init_fixed
790      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
791        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
792        pkg/streamice
793      - shelfice_thermodynamics.F: call shelfice_step_icemass if
794        SHELFICEMassStepping = .true.
795      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
796    
797    checkpoint65h (2014/12/17)
798    o verification/global_ocean.90x40x15, global_ocean_ebm:
799      - update to generic controls.
800    o pkg/ctrl:
801      - ctrl_map_ini_genarr.F: test for igen>0
802      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
803      - move gentim2d part of ctrl_map_ini_genarr.F to
804        new separate routine : ctrl_map_ini_gentim2d.F
805      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
806        add time variable weights and cyclic controls (time mean,
807        seasonal cycle, etc) capabilities to gentim2d
808    o pkg/ecco:
809      - move reading of error, conversion to weights from
810        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
811    o global_oce_llc90, cs32:
812      - activte sbo.
813      - CTRL_SIZE.h : add maxCtrlProc.
814      - activate the new genctrl capabilities.
815      - update following reorganization of global_oce_input_fields.tar.gz  
816    o pkg/ctrl/ctrl_ad_diff.list:
817      - add missing ctrl_init_rec.f
818    o tools/OAD_support/keepOriginal:
819      - add ctrl_init_rec.F
820    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
821      - avoid recomputations of xx_gentim2d_dummy.
822    o momentum diagnostics:
823      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
824        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
825    o pkg/seaice/seaice_lsr.F:
826      - fix computation of BU/BV, make sure they are non-zero, only necessary
827        for cubed sphere exchanges and SEAICE_OLx/y>0.
828        This makes calling s/r fill_cs_corner_rl obsolete (removed).
829    o verification/global_ocean.cs32x15/input.seaice
830      - add test for strong implicit coupling and restricted addtive Schwarz
831        methods for LSR
832      - update results/output.seaice.txt
833    o verification/tutorial_global_oce_biogeo:
834      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
835        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
836        update output_adm,_oadm,_tlm.txt
837    o pkg/dic:
838      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
839      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
840        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
841    o verification/tutorial_global_oce_biogeo:
842      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
843        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
844        update output_adm,_oadm,_tlm.txt
845    o eesupp/src:
846      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
847        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
848    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
849      LSR (following Hutchings et al. 2004)
850      - introduce zetaZ as a global variable (requires adjustments in
851        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
852        in seaice_calc_viscosities.F
853      - new flag SEAICEuseStrImpCpl (default off)
854      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
855        momentum equations
856      - JFNK-solver (preconditioner) adjusted to allow using this method
857        (where it does not have any positive effect)
858    o pkg/seaice
859      - add overlap for restrictive additive Schwartz method also to LSR, but
860        turn it off by default (because it only seems to work for non-cubed
861        sphere/llc topologies)
862    o pkg/autodiff
863      - add extra exchanges in addummy_in_steppging also for mnc output
864    o pkg/seaice:
865      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
866        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
867    o pkg/obcs:
868      - add option to specify domain-connected piece Id along OB though files
869        (for now, only used to diagnose PhiVel; default =1 -> global correction)
870      - modify obcs_diag_balance.F to process each connected-part separately;
871        exclude OB where Id = 0 but keep the full divergence there (-> constant
872        Psi along this portion of OB and all inflow derived from grad(Phi))
873      - add example of OB-conect files in verification/so_box_biogeo/input.
874    o pkg/diagnostics:
875      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
876      a) use non zero matrix element across OB and solve for Phi 1 grid point
877         outside OB (i.e, where tracer OBCS are applied).
878      b) global imbalance of inFlow/outFlow across OB: instead of modifying
879         velocity across OB, spread it uniformly along the OB in the RHS.
880    
881    checkpoint65g (2014/11/19)
882    o pkg/diagnostcis:
883      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
884    o pkg/my82,pp81,kl10:
885      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
886        field diffKr as background diffusivity to set minimum diffusivity value.
887    o pkg/seaice:
888      - add new parameter SEAICEuseEVPrev (for revisited EVP by
889        Bouillon et al 2013)
890      - add SEAICE_evpAlpha/Beta to namelist
891      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
892        involve trivial re-ordering of divisions/multiplications that should not
893        have any effects, but ... they do change the results of lab_sea.hb87 so
894        that only 2 digits of agreement remain, in line with the general
895        instability/fragility of the evp-code. For now, I do not care and just
896        update the verification experiment
897    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
898      - remove xx_genarr2d_numsmooth etc
899      - use xx_genarr2d_preproc etc instead
900      - carry out smooth_correl2D at initialization stage rather than during
901        time stepping.
902      - get smoothOpNb from xx_gentim2d_preproc
903    o global_oce_cs32 :
904      - add test of generic ecco capabilities.
905    o pkg/exf/exf_getsurfacefluxes.F :
906      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
907    o pkg/ctrl,ecco :
908      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
909        is defined.
910    o pkg/seaice: add diagnostics for Delta (deformation parameter)
911    o model/src:
912      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
913        diffusivity (background) is specified but ignored.
914    o verification:
915      - in testreport, convert hostname to lower case for default output dir name
916    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
917    o pkg/dic: add modifications from Hajoon:
918      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
919      - light attenuation: add self-shading effect by climatological Chlorophyll
920        (read from file).
921    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
922        compiles when SEAICE_ALLOW_DYNAMICS is undefined
923    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
924        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
925        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
926        approach where CPP_OPTIONS.h includes an omnipotent
927        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
928    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
929        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
930    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
931        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
932        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
933    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
934      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
935      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
936      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
937      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
938    o pkg/ctrl,ecco,exf :
939      - remove variables associated with NON-generic costs,
940        unless ECCO_CTRL_DEPRECATED is defined.
941      - remove NON-generic NON-obcs controls,
942        unless ECCO_CTRL_DEPRECATED is defined.
943    o pkg/ctrl : added ctrl_local_params.h
944    o pkg/ecco : added ecco_local_params.h
945    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
946        experiments, which will progressively be removed once the
947        experiments are revised to use only generic controls/costs.
948    
949    checkpoint65f (2014/10/13)
950    o pkg/ctrl, ecco, seaice : minor changes in headers
951    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
952        cost function and control capabilities added since checkpoint65c.
953    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
954    o pkg/ecco: increase modularity and improve logic
955      - ecco_toolbox.F (new) : basic operations that are often used,
956        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
957        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
958      - cost_gencal.F (new) : determine filnames and records.
959      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
960      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
961        and exploit the above functions leading to more compact code.
962      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
963      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
964        using_ers, using_gfo, using_mdt is now only defined within gencost)
965    o pkg/ecco: extend generic cost capabilities
966      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
967        capabilities via gencost_preproc (+ _c,_i,_r related params),
968        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
969        gencost_outputlevel arguments to cost_generic
970      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
971        and active_read, making room for gencost_preproc to take effect.
972        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
973      - pkg/ecco/cost_generic.F :
974        compute and store misfit maks*(model-data) in localdif that is
975        then used in cost and for output, output misfit if outlev.GT.0
976      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
977        rather gencost_barfile for deciding whether to write barfile
978      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
979      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
980        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
981      - pkg/ecco/ecco_summary.F : report gencost variables
982      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
983    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
984    o pkg/ecco: internal re-organization
985      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
986        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
987        mv relevant variables definition from ecco_cost.h to ecco.h,
988        make sure gencost routines only include ecco.h)
989      - throughout : add missing CCP switches, rm unused variables,
990        and rm un-necessary CPP switches
991      - throughout gencost routines : replace modelstartdate with
992        gencost_startdate when needed
993      - cost_bp_read.F : use arguments, instead of common blocs
994        so that it can be used also by (new) cost_gencost_bpv4.F
995      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
996      - ecco_phys.F : compute etanFull
997      - ecco_readparms.F : rename using_topex as using_tpj, add
998        bpv4-grace to gencost list, initialize added parameters
999      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1000    
1001    checkpoint65e (2014/09/28)
1002    o pkg/obcs:
1003      - replaced the just-added CPP options with run-time variables
1004        (see pkg/obcs/OBCS_PARAMS.h for details)
1005    o pkg/obcs:
1006      - add additional CPP options for sponge boundary layers
1007        (see pkg/obcs/OBCS_OPTIONS.h for details)
1008    o pkg/atm_phys:
1009      - implement simple (obliquity only, assuming circular planet orbit)
1010        seasonal cycle for incoming insolation ; used when run-time parameter
1011        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1012    o pkg/exf, pkg/ecco, pkg/ctrl:
1013      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1014      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
1015      - implement gentim2d for xx_tauu, xx_tauv
1016    o pkg/ctrl, pkg/ecco :
1017      - fix and complement the generic controls implementation
1018    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
1019        pkg/shelfice/shelfice_thermodynamics.F,
1020        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
1021        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1022      - add weight in CTRL_GET_GEN calls
1023    o pkg/ctrl :
1024      - ctrl_get_gen.F : add weight as input parameter, and apply
1025        it directly rather than using smooth_correl2Dw (to be retired).
1026      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1027    o pkg/ctrl :
1028      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1029        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1030      - re-activate ctrl_summary (call in ctrl_init.F)
1031    o pkg/ctrl/ctrl_cost_gen.F :
1032      - fix CCP brackets, remove un-necessary myiter, mytime
1033    o pkg/ecco, pkg/ctrl :
1034      - remove cost_genctrl.F (now pkg/ctrl/ctrl_cost_driver.F)
1035      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
1036      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
1037      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1038    
1039    checkpoint65d (2014/09/15)
1040    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
1041      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
1042        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1043    o pkg/ctrl/ctrl_map_ini_genarr.F :
1044      - remove compilation failure
1045      - replace hard coded example
1046      - use ctrl_map_ini_gen2D, 3D
1047    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
1048      - on/off switch based upon xx_genarr2d_weight,3d
1049    o src/packages_init_variables.F :
1050      - regroup pkg/estimation calls
1051      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1052        (moved to ctrl_init_variables)
1053    o cost/cost_init_varia.F :
1054      - remove ecco_cost_init_varia
1055        (moved to ecco_init_varia)
1056    o ctrl/ctrl_init_variables.F :
1057      - add CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1058      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
1059    o ctrl/ctrl_map_ini.F :
1060      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
1061        (moved to ctrl_init_variables)
1062    o ctrl/ctrl_map_ini_ecco.F :
1063      - remove ECCO_PHYS (mv to ecco_init_varia)
1064      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1065    o ecco/ecco_ad_diff.list :
1066      - add ecco_init_varia.f
1067    o ecco/ecco_init_varia.F
1068      - new routine
1069    o pkg/streamice:
1070      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1071        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1072      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1073    o pkg/generic_advdiff:
1074      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1075    o pkg/exf:
1076      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1077         xxg_precip capability
1078      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1079    o pkg/ctrl:
1080      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1081    o model/src/load_fields_driver.F :
1082      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1083        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1084    o OpenAD verification experiments:
1085      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1086        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1087        for now, only in pkgs used in OpenAD verification experiments.
1088      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1089        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1090        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1091        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1092    o OpenAD verification tests:
1093      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1094      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1095        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1096      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1097        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1098    o model/src & generic_advdiff:
1099      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1100        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1101        dynamics requires valid tracer forcing only over tile interior but, for
1102        some diagnostics, may need to extend it over 1 point in tile halo region.
1103      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1104        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1105        setting in temp/salt/ptracer_integrate.F
1106    o pkg/dic:
1107      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1108        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1109        in gchem_forcing_sep.F
1110    o pkg/autodiff & obcs:
1111      - add storage of current OB values for U & V (was already done for T & S).
1112    
1113    checkpoint65c (2014/08/30)
1114    o pkg/dic:
1115      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1116        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1117        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1118    o verification:
1119      - new experiment testing OBCS and DIC pkgs, using params & output from
1120        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1121        passage: take OBCS from the last year of a 2 yrs simulation and initial
1122        conditions from t=1.yr while keeping the same forcing.
1123    o model/src:
1124      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1125        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1126    o pkg/diagnostics (Stats-Diags):
1127      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1128        a) refine region where stats are computed, excluding where arrhFac=0 ;
1129        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1130        c) extend regional stats over the region edges (for U or V pt location).
1131    o pkg/gchem:
1132      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1133        pkg/dic is currently changing/updating ptracers values beyond the OB).
1134    o verification (hs94):
1135      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1136        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1137        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1138        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1139    o pkg/ptracers:
1140      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1141        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1142      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1143        with AB-2 code (so that it get tested).
1144    o model/src:
1145      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1146        with AB-2 code (previously only available with AB-3 code).
1147        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1148        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1149        there, by calling CYCLE_AB_TRACER).
1150    o pkg/generic_advdiff:
1151      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1152        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1153        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1154        S/R temp/salt/ptracers_integrate.F
1155    o model/src & pkg/ptracers:
1156      - remove common block variables gT,gS (in DYNVARS.h), except when
1157         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1158      - remove common block variable gPtr.
1159    o model/src & pkgs:
1160      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1161         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1162         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1163         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1164      + change accordingly all calling S/R.
1165      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1166        in S/R temp/salt/ptracers_integrate.F
1167    o pkg/seaice:
1168      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1169        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1170      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1171        in seaice_lsr
1172      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1173        in s/r seaice_lsr_calc_coeffs
1174    o pkg/mdsio:
1175      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1176        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1177        too long (e.g., > MAX_LEN_FNAM/2 )
1178    
1179    checkpoint65b (2014/08/12)
1180    o pkg/matrix:
1181      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1182    o model/src:
1183      - fix initialisation of geothermalFile; compile geothermal-flux code in
1184        natl_box verification experiment.
1185    o model/src & pkg/down_slope:
1186      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1187      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1188        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1189        results at machine truncation level: update output of experiments
1190        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1191    o pkg/diagnostics (Stats-Diags):
1192      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1193        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1194        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1195        times (but Min,Max and StD are still wrong).
1196    o model/src:
1197      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1198        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1199    o model/src:
1200      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1201        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1202        arrays are already updated while adjustments (filters, conv.adjustment) are
1203        still applied later, in S/R TRACERS_CORRECTION_STEP.
1204    o model/src:
1205      - store in common bloc array "rhoInSitu" the virtual potential temperature
1206        anomaly that is used to compute geopotential: this make the atmos code
1207        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1208    o pkg/seaice/seaice_lsr.F
1209      - rename integer variable ilcall to ipass (that's what it is called
1210        in the residual diagnostics
1211      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1212        default) for improved non-linear convergence of the first few steps
1213      - adjust a few comments and add new ones to explain some of the store
1214        directives
1215    o pkg/generic_advdiff (& ptracers):
1216      - re-work the code to check for valid advection scheme and for minimum
1217        size of overlap (now stored in local common bloc in gad_advscheme.F)
1218    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1219      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1220      - add an auxilliary variable "bet" and fix store directives and keys in
1221        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1222        less exact gradients in my tests); but there are still
1223        recomputation warning (although gradients are sort of OK), when
1224        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1225        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1226      - update verification experiments lab_sea.
1227      - change some comments in S/R seaice_calc_viscosities
1228    o model/src:
1229      - if staggerTimeStep=T, always apply exchange to velocity field in
1230        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1231        (independent of using multi-dim advection or not); no effect on FWD run
1232        but affects AD results (at machine truncation level): update output of
1233        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1234        and isomip (oad: 12.d).
1235    o pkg/generic_advdiff:
1236      - stop if doAB_onGtGs is set to FALSE but ignored
1237      - refine warning related to stability of tracer time-stepping
1238        regarding internal wave dynamics.
1239      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1240        on staggerTimeStep & implicitIntGravWave (will now get a warning
1241        if potentially unstable).
1242    o pkg/kl10:
1243      - add new pkg "kl10" for mixing due to internal wave breaking, from
1244        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1245        (contribution from Jody Klymak), tested in verification experiment
1246        verification/internal_wave/input.kl10/
1247    o isomip experiment:
1248      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1249        (input.htd) and update the output.
1250    o cd_code experiments:
1251      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1252        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1253        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1254        update the corresponding output.
1255    o pkg/seaice:
1256      - reduce the number of include files and store directives in
1257        S/R seaice_lsr_tridiagu/v
1258      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1259        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1260        get rid off one store directive (a TAF bug?)
1261      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1262        S/R seaice_lsr_tridiagv to change the loop range for consistency
1263      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1264      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1265        S/R seaice_lsr_tridiagu/v (requires update of
1266        offline_exf_seaice/input.dyn_jfnk)
