4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate  o model/src:
8    AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than    - more robust ordering of column thickness integral (=Sum_k(drF*hFac) )
9    ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,      to get same expression (regarding machine truncation) in different places
10    approach where CPP_OPTIONS.h includes an omnipotent      in ini_masks_etc.F (e.g., rSurfC,W,S is now exactly zero when it should).
11    ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').      Update forward output of experiments: global_ocean.cs32x15 (all 5 except
12  o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where      viscA4), isomip (x3), tutorial_global_oce_in_p & tutorial_plume_on_slope.
13    ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.  o pkg/shelfice:
14      - ALLOW_SHIFWFLX_CONTROL: move setting of maskSHI from shelfice_update_masks.F
15        to shelfice_init_fixed.F
16      - change S/R SHELFICE_UPDATE_MASKS to SHELFICE_INIT_DEPTHS (still called from
17        ini_masks_etc.F for now) to update ocean upper boundary position according
18        to ice-shelf topography (instead of directly updating hFacC).
19    o model/src:
20      - move call to CTRL_INIT & CTRL_ADMTLM from the middle to the bottom of
21        packages_init_fixed.F to allow other pkgs to set mask and weight fields.
22    
23    checkpoint66f (2017/04/06)
24    o model/src:
25      - add specific run-time param to select level of printed plot-field-maps,
26        set by default to debugLevel. Remove internal param "printDomain".
27    o pkg/seaice:
28      - add flag to add snow mass to seaiceMassC/U/V, the default is
29        SEAICEaddSnowMass=.FALSE., not to change previous results
30    o pkg/bling
31      - Bug fix in bling_production regarding unit conversion for diagnostics
32        being put in the wrong place
33    o model/src:
34      - add back recomputation of rSurfW & S to ensure consistent column thickness
35        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
36        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
37        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
38    o pkg/autodiff:
39      - clean-up "checkpoint.flow"
40    o pkg/rw (Contribution from Jody Klymak):
41        option to set mds file suffix as function of time in simulation:
42        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
43           to select file suffix format; by default (=0), use iteration number;
44        *) add simple routine to return file suffix according to rwSuffixType;
45        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
46           use new S/R to get file suffix, except for debug output file (diagFreq)
47           and pkgs offline & rbcs input files.
48    o pkg/rw:
49      - uniform processing of "I10" suffix across writing fld routines; used to
50        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
51        (similar to cg3d.F, cg3d_ex0.F)
52    o pkg/mom_vecinv:
53      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
54        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
55    o pkg/bling:
56      - Many small changes intended to clean the code.
57        Unnecessary ADJOINT_SAFEs removed ;
58        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
59        diagnostics added.
60    
61    checkpoint66e (2017/03/14)
62    o pkg/exf:
63      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
64        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
65        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
66        avoid any dynamic allocation ;
67      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
68        read-in ; add warning when file is read-in but not used within pkg/exf ;
69        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
70      - update exf_summary.F (print {FLD}RepCycle).
71    o verification/global_with_exf:
72      - switch on exf interpolation in AD test (just like the forward test)
73    o pkg/mom_vecinv:
74      - add storage directives to avoid recomputations within mom_vecinv.F
75        which were generating seg. fault with gfortran -devel
76    o pkg/ctrl, pkg/smooth:
77      - initialize array halos which were generating seg. fault with
78        gfortran -devel in adjoint mode
79    o pkg/exf:
80      - for each input field, enable to specify a field specific repeat-cycle
81        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
82    o verification/lab_sea:
83      - update AD results of primary test and noseaicedyn test after switching
84        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
85        check stays about the same.
86    o pkg/exf:
87      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
88      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
89    o pkg/bling, USE_EXFCO2 code:
90      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
91      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
92    o pkg/exf:
93      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
94      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
95        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
96        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
97      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
98        EXF_INIT_FLD) and update calls in exf_init_varia.F
99      - For now, for backward compatibility, keep a simplified version of S/Rs
100        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
101      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
102        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
103    o tools/genmake2:
104      - replace "bc -l" (only used once) by "expr" (already used).
105    o verification/global_ocean.cs32x15:
106      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
107        Note: exf setting (data.exf) can be compared to other exf secondary exp
108        "seaice" (kept with useCAL=T) which has same time dependent forcing.
109    
110    checkpoint66d (2017/02/13)
111    o pkg/exf:
112      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
113        early on (in packages_boot.F) to stress this change in pkg setting.
114      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
115    o model/src:
116      - move call to ecco_phys to end of time step; this may induce minor
117        cost function changes by shifting time averages by one time step
118        for some variables; this revision resulted in changed adjoint results
119        in MITgcm_contrib/verification_other/global_oce_cs32
120    o pkg/exf:
121      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
122        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
123        e.g. precip, are not available.
124    o pkg/flt:
125      - flt_init_varia.F: use pickupSuff if specified
126      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
127        intermediate, step towards completing pkg/exch2 support within pkg/flt;
128        ifdef DEVEL_FLT_EXCH2 then:
129        - flt_init_fixed.F: comment out stop
130        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
131        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
132        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
133        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
134    o tools/genmake2 & pkg/pkg_depend:
135      - define new type of pkg dependency rule ("=pkg_x"), less strict than
136        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
137        (-pkg_x in packages.conf).
138      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
139      - add "+cal" to dependency list of pkg/ecco (needed to compile).
140      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
141    o utils/matlab:
142      - adding ocean_basin routines for defining basin masks.
143    o pkg/exf:
144      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
145        arguments, allowing to check (and stop) if parameter setting of
146         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
147        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
148        for backward compatibility.
149      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
150        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
151    o pkg/bling (USE_EXFCO2 code):
152      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
153        by adding a call to S/R EXF_GETFFIELD_START.
154    o pkg/exf:
155      - allows to compile without pkg/cal (but disabled by current dependency
156        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
157        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
158        of {FLD}startdate1 & date2 ; consistency check not yet coded.
159    o verification/global_ocean.cs32x15:
160      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
161        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
162    o pkg/exf:
163      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
164        calculations); change FWD experiment global_ocean.cs32x15
165        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
166    o pkg/exf:
167      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
168         {FIELD}startdate to {FIELD}StartTime
169        Note: new name also fit better the content, i.e, a start time in second.
170    o eesupp/src:
171      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
172    o pkg/exf:
173      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
174        to allow to read-in Sensible & Latent Heat flux ;
175      - simplify pkg/exf main options:
176        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
177           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
178           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
179        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
180           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
181        3) improve options documentation in EXF_OPTIONS.h.
182    o pkg/ecco:
183      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
184        ecco_summary.F: add passive tracer cost functions to gencost;
185        m_ptracer and m_boxmean_ptracer
186    o pkg/ctrl:
187      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
188        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
189        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
190        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
191    o model/src:
192      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
193        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
194    o pkg/exf:
195      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
196        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
197    
198    checkpoint66c (2017/01/19)
199    o verification:
200      - add new option "-src" to testreport to only produce source code (*.f),
201        including taf output src code (if using '-adm'/'-tlm' option).
202    o pkg/exf:
203      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
204    o pkg/diagnostics:
205      - add run-time variable diagMdsDir to specify a subdirectory for
206        diagnostic output when mds is being used and mdsioLocalDir is not.
207    o pkg/mnc:
208      - mnc_utils.F: edit stop message
209    o pkg/autodiff:
210      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
211        add HAVE_SYSTEM bracket around system call to mkdir
212    o pkg/profiles:
213      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
214        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
215      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
216        add HAVE_SYSTEM bracket around system call to mkdir
217    o pkg/smooth:
218      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
219      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
220      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
221    o pkg/exf:
222      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
223        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
224        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
225      - summary: skip detailed field report if not used (empty file-name).
226    o tools/xmakedepend:
227      - In case line editor "ed" is missing, switch to "sed" command to clean-up
228        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
229    o pkg/exf:
230      - change definition of "hflux" input file to always include Short-Wave;
231        this is now consistent with hflux computation (if using bulk-formulae)
232        and hflux diagnostic & documentation (in EXF_FIELDS.h).
233    
234    checkpoint66b (2016/12/01)
235    o model & momentum pkgs:
236      - implement fully implicit bottom friction combined with implicit surf.
237        pressure, for now, only in hydrostic formulation:
238        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
239          and run with selectImplicitDrag=2 ;
240        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
241      - partial implicit time-stepping (bot. friction + vert. visc first, then
242        surf. press) corresponding to selectImplicitDrag=1 should be applicable
243        to NH formulation but not available until we solve for surf. pressure
244        increment (instead of full etaN).
245      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
246        with implicit vertical viscosity.
247    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
248      - this is a first version that includes many regularisations that may
249        not all be necessary, to be sorted out,
250      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
251      - change one verification experiment in seaice_itd to use and test new code
252      - seaice_growth: catch a case where the argument of log can be zero
253        or smaller (important for code stability)
254    o model/src:
255      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
256        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
257        similar A.X'=Y' system (with same matrix A) in subsequent calls;
258        switch based on errCode (In/Out) argument value; in calling routines,
259        initialise errCode before first call.
260    
261    checkpoint66a (2016/10/18)
262    o pkg/bling:
263      - BLING package now loads in atmospheric pCO2 file using exf package routines
264        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
265    o model/src & pkg/ptracers:
266      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
267        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
268        implicitDiffusion (respectively) are used (even without momImplVertAdv
269        or temp,salt,PTRACERS_ImplVertAdv).
270    o model/src & generic_advdiff:
271      - add parenthesis in main diagonal calculation of implicit vertical
272        diffusion matrix (impldiff.F & gad_implicit_r.F).
273        This affects results at machine truncation level; update output of many
274        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
275    o pkg/mom_commom & generic_advdiff:
276      - add deep atmosphere and anelastic scaling factor in implicit vertical
277        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
278    o model/src:
279      - remove few unnecessary temp array copies in solve_tridiagonal.F
280        & solve_pentadiagonal.F
281    
282    checkpoint65z (2016/09/28)
283    o pkg/seaice: fix multithreading for seaice_fgmres.F
284      - remove unecessary variables from common blocks
285      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
286        basis, that are stored in commom blocks (including integer variable i1)
287      - clean up code a little by removing commented lines that refer to
288        original code
289      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
290    o MITgcm manual:
291      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
292        preliminary documentation for generic controls (8.3; ctrl.tex),
293        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
294        ecco_costfunction.tex
295    o pkg/ecco:
296      - update and cleanup list of CCP options
297      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
298        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
299      - add checks that retired run-time options are not used, and in relation
300        to gencost_mask and gencost_errfile
301      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
302        gencost_nrecperiod
303      - fix m_eta computation for virtual salt flux case
304      - add m_horflux_vol case (selected via gencost_barfile) that computes
305        transports via cost_gencost_boxmean (gencost_flag=-3)
306      - use gencost_flag more systematically (i.e., avoid using gencost_name)
307        for code switches (aside from physical variable selection)
308    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
309      attempt appears to be a bit of a hack and my need some repair down the road
310    o pkg/exf:
311      - interpolation near South Pole: fix criteria on input field latitude.
312    o pkg/icefront & pkg/exf:
313      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
314        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
315    o pkg/exf:
316      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
317        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
318        (add suffix "_out" instead of a prefix); keep same record number as in
319        input file but always write record 1 first (to avoid a STOP in I/O S/R).
320        Change output file content by writing interpolated field before applying
321        land-sea mask (helpful for debug).
322      - 2 compon. vector interpolation with rotation: apply scaling factor on
323        each compon. (Eastward and Northward) just before rotation.
324    o pkg/bling:
325      - Cleaned package. Removed not needed code and comments.
326      - adjoint example now works
327        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
328    o pkg/ptracers:
329      - add Bruno Deremble's code to complete the linear surface correction
330        for tracer conservation;
331      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
332    
333    checkpoint65y (2016/07/29)
334    o pkg/debug (stats):
335      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
336        proc/thread mapping);
337      - fix Min & Max for case where 1 thread has only empty tiles;
338      - use RL variable to count number of wet grid points (with big domain,
339        can be too large to fit into integer*4).
340    o pkg/monitor:
341      - use RL variable to count number of wet grid points (but used only for del2)
342      - add new routine to compute Advective CFL within tracer time-stepping with
343        writing delayed until next monitor output.
344    o pkg/obcs:
345      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
346    o pkg/cal:
347      - calandar-dump: treat case myTime < timePhase in the same way as in
348        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
349    o pkg/dic & seaice:
350      - fix compilation of ocean component for coupled atm+ocn model with
351        seaice dynamics & dic.
352    
353    checkpoint65x (2016/06/11)
354    o add a license text file in main MITgcm tree.
355    o added pkg/bling:
356      - intermediate complexity biogeochemical model
357      - see bling_description.txt for details
358      - verification experiment is global_oce_biogeo_bling (for now, in
359        Contrib/verification_other/); tested daily on baudelaire with gfortran.
360      - add entry point in pkg/gchem for new pkg "bling".
361    o pkg/seaice: fix tensile stength computation
362      - replace global field tensileStrength by tensileStrFac
363      - tensileStrFac can be computed once in S/R seaice_init_varia
364      - fortunately that does not affect any verification results
365    
366    checkpoint65w (2016/05/12)
367    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
368         with ECCO_CTRL_DEPRECATED defined
369    o verification/global_ocean.cs32x15:
370      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
371        with "selectNHfreeSurf=1".
372    o model/src (non-hydrostatic free-surface):
373      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
374        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
375      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
376        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
377        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
378        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
379      - Update output (changes at machine truncation level) of verification exp:
380        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
381        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
382    o pkg/seaice: ITD code
383      - fix picking up from a single category model by initialising
384        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
385      - split a long warning message in seaice_check_pickup.F into two lines,
386        because NEC SX-ACE cannot deal with the long line.
387    o model/src:
388      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
389    o pkg/seaice:
390      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
391    o pkg/seaice:
392      - add basal stress as parameterisation for grounding ice
393        following Lemieux et al. (2015)
394      - turn on by setting new parameter SEAICEbasalDragK2 to a value
395        larger than 0. Lemieux et al. (2015) recommend 15.
396      - The adjoint complains with extra recomputations so there is also a
397        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
398        order to postpone the problem
399      - compile the new code in lab_sea
400    o verification/halfpipe_streamice:
401      - update both TAF and OpenAD adm output (machine truncation differences)
402    
403    checkpoint65v (2016/04/08)
404    o verification/advect_xz:
405      - increase overlap size from 3 to 4 and add new secondary test for PQM
406        advection scheme (with mono & wino limiter).
407      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
408    o model/src:
409      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
410        added phi0Ref) to set vertical axis origin and phiRef origin;
411        keep Ro_SeaLevel for backward compatibility (with a warning).
412       According to coordinate and fluid type:
413        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
414        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
415        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
416        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
417      - remove Ro_SeaLevel from ATM experiment parameter files;
418      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
419        complement; update output.txt (changes at machine truncation level).
420    o pkg/seaice/seaice_evp.F
421      - simplify computation of deltaZ and zetaZ to simple averaging following
422        Bouillon et al. (2013). This removes a lot of code, but also changes
423        verification experiment lab_sea.hb87 -> updated
424    
425    checkpoint65u (2016/03/14)
426    o pkg/generic_advdiff:
427      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
428        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
429        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
430        testing and not for actual use.
431    o model/src:
432      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
433        origin r = rF(1);
434      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
435        in EOS for height coordinate: enable to include NH Pressure or to use
436        more accurate pressure vertical profile; options not linked to EOS type
437        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
438      - start to implement variable gravity (along vertical): for now, only with
439        z-coords (not even z*).
440      - add Ideal Gas equation of state for height coordinate.
441      - update OpenAD output (affected at machine truncation level) of exp:
442        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
443    o pkg/exf:
444      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
445        of exf interpolation (before any rescaling, rotation or interpolation
446        to velocity point) for each field that gets loaded from file. This option
447        identically mimics the input file organization (e.g. record numbers in year
448        by year input files) besides the change in horizontal grid.
449      - add rotateStressOnAgrid run-time switch so that wind stress fields
450        can be provided on the A-grid in zonal/meridional direction and
451        rotated on the fly. This only applies to the case when the exf
452        interpolation is off and rotateStressOnAgrid is false by default.
453    o model/src:
454      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
455        it's also used with pkg/atm_phys) and add few more parameters (but still
456        inactive, src code yet to come)
457    
458    checkpoint65t (2016/02/10)
459    o pkg/atm_phys:
460      - from Ruth Geen: add optical depth dependence on CO2 concentration.
461    o model/src:
462      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
463        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
464        Update output of exp. deep_anelastic (changes at truncation level).
465    o tools:
466      - add a hack in "remove_comments_sed" (used only with TAF) for recent
467        version of OpenMPI (shipped with FC.23): comment out the new header
468        file "mpif-sizeof.h" which causes problems to TAF.
469    o pkg/seaice:
470      - change the termination criterion so that maxits (SEAICElinearIterMax)
471        has an effect
472      - unify iteration parameters for implicit solvers (JFNK and Picard)
473        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
474        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
475        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
476        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
477        SEAICEnonLinTol     replaces JFNKgamma_nonlin
478      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
479      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
480        use with SEAICEuseKrylov
481    o pkg/seaice/seaice_lsr.F
482        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
483        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
484        an effect.
485    o pkg/seaice: add two new parameters
486      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
487        parameter is not in any namelist)
488      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
489        a preconditioner for the non-linear Newton iteration of the JFNK
490        solver
491    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
492      affects some experiments at truncation level:
493      - global_ocean.cs32x15.icedyn (11 digits),
494      - global_ocean.cs32x15.seaice (11 digits),
495      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
496      - also update global_ocean.cs32x15 adjoint and tangent-linear results
497    o pkg/salt_plume & pkg/thsice:
498      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
499        connect salt_plume flux to ATM-OCN coupling pkgs interface:
500       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
501         export to coupler interface) even without compiling pkg/salt_plume ;
502       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
503         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
504    o pkg/dic:
505      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
506        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
507        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
508      - move also update with values from ATM-OCN Coupler in the same new S/R
509        (previously done in ocn_apply_import.F).
510    o tools/adjoint_options:
511      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
512        has been changed on Jan 14, 2016.
513    o pkg/ggl90:
514      - add alternative discretisation of vertical shear (off by default), to
515        compute the mean (@ grid-cell center) of vertical shear compon instead of
516        vertical shear of mean flow (@ grid-cell center).
517      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
518        results on adjacent faces of cubed-sphere grids; this fix the restart.
519    o pkg/atm_compon_interf:
520      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
521        pass last value, stored directly before export to CPL ;
522        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
523      - remove atmSLPr from pickup files (no longer needed for restart)
524    
525    checkpoint65s (2016/01/13)
526    o eesupp & genmake2:
527       - first check for Function ETIME and, if it fails, then check for subroutine
528         ETIME and consistent output; use the appropriate version in timers.F
529    o model/src:
530      - to check restart test, add option to apply EXCH to U,V earlier, just before
531        integr_continuity; turned off by default.
532    o pkg/dic:
533      - remove CPP option USE_ATMOSCO2 (not needed)
534    o tools/tst_2+2:
535      - try to ignore difference between +0 and -0 in binary file, causing test
536        to fail for no good reason.
537    o eesupp & genmake2:
538      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
539        but also check (in genmake2) that test runs and returns meaningful results.
540    o coupler pkgs:
541      Finish implementation of optionally-exchanged variable switches (started on
542       Nov 12) with addition of few more exchanged fields, including 2-way exchange
543       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
544       advection in OCN component; this requires sequential coupling.
545      coupler (pkg/atm_ocn_coupler):
546      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
547        routines (useful for debug).
548      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
549         flux, DIC fields) if corresponding switch is ON.
550      - add option to export RunOff to OCN (to use for DIC river input)
551      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
552      components (pkg/atm_ & ocn_compon_interf):
553      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
554        optionally exchanged fields; add a check & stop in cpl_readparms.F.
555        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
556        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
557      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
558        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
559      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
560      - hold in common block coupler optionally-exchanged variable switch
561        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
562      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
563        this is intended to replace the OCN cplFldtave.* output files (not updated
564        to contain new additional exchanged fields).
565    o pkg/dic:
566      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
567    o pkg/thsice:
568      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
569        and writing of thsice pickup files.
570    o pkg/atm_compon_interf:
571      - move all field individual export-call out of cpl_export_import_data.F
572        into new S/R ATM_EXPORT_FIELDS
573    o pkg/atm_compon_interf:
574      - store state variables (for now, only thSIce fields) just before beeing
575        exported (in cpl_export_import_data.F, like on ocean side) instead of from
576        atm_store_my_data.F like all exported fluxes.
577      - new version of pickup_cpl: write field names into meta file and read meta
578        file to find field postion in pickup. Also only write/read fields meeded for
579        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
580    o pkg/dic:
581      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
582    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
583        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
584        value can be from domain [0,1] to average between the two methods
585    o pkg/atm_phys:
586      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
587        hold fixed in time).
588    
589    checkpoint65r (2015/12/21)
590    o pkg/seaice:
591        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
592        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
593    o pkg/seaice:
594      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
595        when SEAICEscaleSurfStress=.TRUE.,
596      - apply areaW and areaS in S/R seaice_calc_lhs
597    o pkg/atm_phys:
598      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
599        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
600        for individual contribution (convection, LSC cond, radiation)
601      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
602        information); activated with: solar_exponent=0. and wv_exponent=-1.
603    o pkg/ggl90:
604      - within IDEMIX add upper limit for horizontal group velocity to
605        avoid instability problems in the explicit horizontal diffusion term for
606        long time steps or high resolution
607    o pkg/diagnostics:
608      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
609        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
610    o testreport:
611      - remove "-v" (verbose option) in default mpirun command.
612    o pkg/seaice/seaice_growth:
613      - catch potential division by zero in ITD code, does not change
614        verification results
615    o pkg/ecco:
616      - retire old codes to the Attic. The calls to retired functions are
617        left in a commented form in case they ever need to be re-activated.
618      - ecco_check.F: issue warning if any old CPP option is
619        defined that corresponds to retired codes -- then stop.
620    o pkg/atm_compon_interf:
621      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
622        coupler: use last time-step value instead of average over cplSendFrq_iter
623        time-step, similar to what is done for seaIceMass.
624        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
625    o eesupp & genmake2:
626      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
627        <= remove until a fix is found for some ifort version on ia32 machine.
628    o pkg/seaice/seaice_evp:
629      - refine residual computation
630    
631    checkpoint65q (2015/11/18)
632    o pkg/seaice/seaice_evp:
633      - fix residual computations so that they no longer affect the actual
634        simulation code
635      - fix seaice_readparams to be able to actually set new parameters
636        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
637    o model/src:
638      - fix wrong truncation (single prec) from "FLOAT" function in expressions
639        like: deltaT*FLOAT(myIter) when myIter is large:
640         a) replaced by DFLOAT (if not seen by TAF);
641         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
642    o pkg/aim_v23:
643      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
644        when pickupSuff is set ; do write rolling pickups + at the end of the run.
645    o pkg/atm_ocn_coupler + ocn_compon_interf:
646      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
647        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
648        add corresponding call in DO_OCEANIC_PHYS.
649    o coupler pkgs:
650      Start a new way to set-up optionally-exchanged variables (previously, only
651       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
652       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
653       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
654       compononent param default can be set accordingly).
655      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
656       but rather applies to a group a fields (going both ways like for DIC)
657       and corresponds to an option of coupling config.
658      coupler (pkg/atm_ocn_coupler):
659      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
660        and read namelist directly (without eessup S/R calls) instead of
661        in the very un-flexible old way, 1 param per line, in fixed order;
662      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
663        cleanly in CPL_CHECK_CPLCONFIG
664      - add new coupling-exchange selectors (some not yet active) including
665        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
666                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
667      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
668        component ; called directly from coupler.F, after comp. registrations;
669      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
670         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
671          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
672      components (pkg/atm_ & ocn_compon_interf):
673      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
674        CPP header file in all pkg source files.
675      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
676        ATM/OCN_CHECK_CPLCONFIG;
677      - add error-counter to track errors (e.g., in "data.cpl") and to stop
678        cleanly in ATM/OCN_CHECK_CPLCONFIG;
679      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
680        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
681        before PACKAGES_READPARMS;
682      verification/cpl_aim+ocn/:
683      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
684        "data.cpl" for coupler (in input_cpl).
685    o eesupp/inc:
686      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
687        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
688        to always cumulate tile local-sum in the same order (still uses
689        MPI_Allreduce like standard code).
690      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
691        that are now identical to standard version (in eesupp/inc).
692    o pkg/shelfice:
693      - add SHELFICETransCoeffTFile for initializing spatially varying
694        heat and salt transfer coefficients
695    o pkg/atm_compon_interf & ocn_compon_interf:
696      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
697        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
698      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
699    o pkg/atm_ocn_coupler:
700      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
701    o pkg/rbcs:
702      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
703        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
704      - add a short report (to STDOUT) about RBCS-mask settings.
705    
706    checkpoint65p (2015/10/23)
707    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
708        there is no adjoint test for EVP, we don't know what it does to the adjoint
709        solution, but at least there are no more recomputation warnings left
710    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
711        a chance of giving the same results as a fully converged VP (JFNK) solver
712    o tools/adjoint_options/adjoint_diva:
713      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
714    o pkg/streamice:
715      - spotted bug in streamice_driving_stress using dyG where should have been dxG
716    o pkg/exf:
717      - remove STOP statement that prevented to use wind or (wind-)stress
718        interpolation for constant-in-time forcing fields (wind/stress period = 0).
719    o pkg/seaice:
720      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
721        5 additionals 2D fields and 6 new store directives
722      - change logic in seaice_readparms.F: EVP code can now be turned on in
723        various ways, setting SEAICE_deltaTev is no longer required,
724        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
725        or SEAICEaEVPcoeff
726    o pkg/shelfice/shelfice_thermodynamics.F
727      - redefining uLoc/vLoc to u/v, instead of 2u/v
728    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
729      - this is an intermediate state of a truely converging EVP that has
730        the potential of outperforming implicit VP methods, I do not recommend
731        using it yet.
732      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
733        and all parameters are hardwired
734      - for convergence it still requires very smooth regularisations, that means,
735        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
736        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
737        specific averaging appears to be required, still subject to tuning
738      - still needs cleaning and I need to turn parameter into runtime parameters
739      - add code to compute and print residuals of iteration, compile with
740        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
741    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
742      that entered with r1.54 on Sep04, 2015, -> update results
743    
744    checkpoint65o (2015/09/14)
745    o pkg/mom_vecinv & mom_common:
746      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
747        called from there.
748      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
749        allows to use Vector-Invariant form in deep atmos and anelastic formulation
750    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
751      and Koenig-Beatty+Holland (2012)
752      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
753      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
754      - requires an extra input argument for S/R seaice_calc_viscosities
755      - tensileStrength's depth dependence is different from Itkin et al. (2015)
756        (to be changed and played with, for now exponential)
757    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
758      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
759        by AREA according to Connelly et al. (2004), JPO.
760      - For EVP and the LSR solver, the implicit part of the drag term is
761        the only non-zero term in the denominator when there is no ice (which
762        prevented running the model with zero ice-ocean drag). If
763        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
764        (or zero main diagonals BU/BV) which need to be caught. A practical
765        consequence is that for open water, the momentum equation reduce
766        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
767        they happen to be zero, often leading to a non-zero solution over
768        open water.
769    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
770        efficient EVP method.
771      - introduce area-weighted averages for e12 (analogously to
772        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
773        remain, but also changing the order of terms in the previous average
774        changed the results as much) -> update experiment
775      - add SEAICE_DELTA_SMOOTHREG code
776      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
777        TEM-code
778      - adjust loop bounds so that only required fields are computed
779      - add new averaging code for zetaZ/deltaZ (again similar to
780        seaice_calc_viscosities.F), inactive by default for now (will change
781        results again), but will replace old code eventually
782    o eesupp/src:
783      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
784        to always cumulate tile local-sum in the same order
785        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
786        Still uses MPI_Allreduce (like standard code) but on array of tiles
787        and should be faster than GLOBAL_SUM_SEND_RECV code.
788      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
789        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
790      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
791         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
792         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
793         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
794         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
795    
796    checkpoint65n (2015/07/29)
797    o pkg/thsice:
798      - add a warning when used with pkg/aim but without updating SST
799        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
800    o pkg/offline:
801      - change where Offline-Fields are loaded, from load_fields_driver.F to
802        directly within FORWARD_STEP, just after updating iter number and time;
803      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
804        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
805       These changes allow:
806        a) to recover exactly on-line results using deltaToffline=deltaTClock,
807        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
808        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
809        time-step, both with GM & KPP files and with recomputing these fields;
810        b) no needs to switch on staggerTimeStep anymore;
811        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
812      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
813    o pkg/offline:
814      - change (rarely used) offset-iteration parameter to an offset time (in s):
815        can easily recover previous offset-iter effect by setting offset-time
816        (offlineTimeOffset) to offset-iter x deltaToffline;
817      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
818        in KPP as part of surface buoyancy forcing) in offline run.
819      - fix ptracers KPP non-local term in the case where KPP is re-computed.
820    o OpenAD
821      - Adding preliminary ggl90 test to OpenAD verification.
822        Config. with ggl90 currently diverges after 64 time steps
823        so will need more work to become more stable
824      - Adding preliminary kpp test to OpenAD verification.
825        required small tweakes in kpp_routines.F
826      - Merge and update from Krishna Narayanan's contrib area:
827        * Add one variable for preliminary OpenAD DIVA
828        * Add replacement time-stepping for OpenAD DIVA
829        * genmake2 flag -diva (but only for OpenAD; preliminary)
830        * required modifs for OAD_support
831        successful preliminary test for tutorial_global_oce_biogeo/
832    o pkg/seaice:
833      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
834      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
835        delta with a smooth function in s/r seaice_calc_viscosity
836        (no effect on EVP)
837      - rename local suffix "sqr" into "sq" for more consistent variable names
838    o pkg/seaice:
839        add new parameter SEAICE_deltaMin that is used ***only***
840        for regularizing Delta (and nothing else, like the parameter
841        which is also used for all sorts of things SEAICE_EPS).
842        Defaults to SEAICE_EPS for backward compatibility only.
843    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
844        the wrong key by inialising it before use -> fixes a recomputation
845        problem but does not fix the gradient
846    o pkg/layers:
847      - move resetting of flux arrays to outside the iLa loop
848        (this caused layers_diapycnal to not work with more than one layer coord.)
849      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
850    o pkg/layers:
851      - remove from common block 3D layers fields (used to diagnose transport
852        in tracer coords) and declare them as local arrays in layers_calc.F
853    o pkg/seaice:
854      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
855        in lab_sea forward experiment (changes results -> updated)
856      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
857    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
858       computations; for SEAICE_VECTORIZE_LSR
859      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
860        sweep to the outside,
861      - remove store directives and add "CADJ loop sequential" directives
862        in analogy to model/src/solve_tridiagonal.F
863      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
864        boundaries to yield more readable code. This has also the charming side
865        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
866        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
867        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
868        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
869        an additional option)
870       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
871       but the adjoint gradients (which are affected by this change) still explode.
872    o coupler (atm & ocn _compon_interf):
873      - avoid using Exch2 IO mapping if not suitable.
874    
875    checkpoint65m (2015/06/15)
876    o pkg/layers:
877      - clean-up old parameters setting (from Sep 2012):
878        + remove old parameters setting from common block (declared locally);
879        + stop if any old parameter is mixed with new parameters;
880        + check for valid or consistent parameter setting (e.g., layers_name)
881      - check that layers_bounds for Pot.Density are in the right range;
882        this is supposed to catch un-updated setting after recently shifting
883        potential density field "prho" by -1000 (now in "sigma" scale).
884    o pkg/layers:
885      - Added missing call to layers_fill for keeping track of tottend in
886        pkg/diagnostics/diagnostics_fill_state.F
887    o pkg/layers:
888      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
889        of diapycnal fluxes
890    o pkg/layers:
891      - reverted changes to interpolation to previous treatment; there
892        was never actually a problem
893    o pkg/layers:
894      - fix interpolation of layers tracers in the presence of partial cells
895      - add lots of new functionality to compute water mass transformation
896        (enabled by CPP flag LAYERS_THERMODYNAMICS)
897      - add new calls from main code (diags_oceanic_surf_flux.F,
898        thermodynamics.F, impldiff.F) and gad to save the necessary fields
899        for layers_thermodynamics calculations
900    o pkg/ptracers:
901      - add capability of stepping a passive tracer forward without advection
902        by setting PTRACERS_advScheme to 0.
903    o pkg/diagnostics:
904      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
905    o pkg/layers:
906      - shift potential density field "prho" by -1000 for density layer averaging so
907        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
908        Note that density bin boundaries (layers_bounds in data.layers) have
909        to be set accordingly (i.e., shifted, in sigma scale).
910    o pkg/layers:
911      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
912      - fix calculation of layer non-weighted velocity and layer probability
913      - add diagnostics for pot.density used for layer averaging
914    o pkg/seaice:
915      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
916        positiveness, modify a few comments and improve variable names,
917      - the changed computation of deltaC affects most seaice-related
918        experiments at the truncation level.
919        seaice_itd.thermo is affected by far the most, with
920        only 7 digits of agreement remaining; update experiments.
921    
922    checkpoint65l (2015/05/04)
923    o pkg/shelfice:
924      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
925        factor drKp1 to zero where it is negative (ie. do not use
926        SHELFICEBoundaryLayer if hFacC>1)
927      - the same for factor drLoc in shelfice_forcing.F
928    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
929        with modules in ptracers, when using testreport option "-small_f"
930    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
931      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
932    o verification/testreport
933      - add new option -small_f
934        with this option testreport first makes the target small_f (*.f files)
935        before running make (all). This is useful for explicit inlining when
936        all sources need to be full available.
937    o pkg/exf/exf_interp.F:
938        remove previous changes related to reverse (decreasing) input grids latitude
939    
940    checkpoint65k (2015/04/01)
941    o pkg/ecco:
942        fix missing cosphi initialization; use eccoiter in place of optimcycle;
943        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
944        instead of active read/write
945    o pkg/ctrl:
946        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
947        instead of active read/write.
948    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
949        return if .NOT.useAUTODIFF
950    o pkg/seaice: add CPP brackets (cost function related).
951    o model/src:
952        add useAUTODIFF run time switch.
953    o pkg/exf/exf_interp.F:
954        add code to allow input grids with latitude starting in the north (i.e. when
955        j=1 corresponds to northern edge of field); modify global_with_exf to test
956        this feature.
957    o verification/testreport:
958      - replace "grep -A3" with POSIX conformal sed command, because there are
959        implementations of grep that cannot do contextual searches
960      - replace "cat -n" by "nl" (two occurrences), because not all implementations
961        of "cat" have the option "-n"
962    o model/src:
963        add new file gsw_teos10.F that contains 3 functions, more or less a copy
964        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
965        convert from conservative to potential temperature. For now they are not
966        called anywhere.
967    o pkg/ggl90: make "useIDEMIX" useful
968      - re-organize code in s/r ggl90_calc a little to move computations that
969        are different for idemix into separate loops (changes verification
970        experiment idemix at truncation level, 12 digits remain -> updated)
971      - requires 2 new 2D fields KappaM, verticalShear
972      - make hFacI and recip_hFacI local 3D variables that are passed to
973        s/r ggl90_idemix
974      - fix and improve some comments
975    
976    checkpoint65j (2015/02/25)
977    o pkg/openad
978      - synchronize seawater.F with version in model/src: replace routine
979        body of sw_temp by calling sw_ptmp and fix/add a few comments.
980    o pkg/mnc:
981      - change default value of pickup_read/write_mnc params to FALSE
982        (since few features are missing in reading MNC pickup files).
983    o model/src:
984      - change default (background) vertical diffusivity for salt to be the
985        temperature (background) vertical diffusivity.
986      - change background vertical diffusivity in vertical mixing pkgs ggl90,
987        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
988        This makes ptracers default diffusivity (that uses salt diffKr) more
989        consistent with vertical mixing schemes.
990    o verification/testreport:
991      - fix typo in "-pcls" option ;
992      - put temp files in /tmp (instead of in local dir)
993      - add option "-ncad" to use genmake2 new option "-nocat4ad"
994      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
995    o pkg/ggl90 (idemix code):
996      - apply few fixes ; add some missing "_d 0" ; update output of exp.
997        global_ocean.90x40x15.idemix
998    o OpenAD
999      - enable active file I/O and begin removal of work-around code
1000        for OpenAD for handling control variables (memory vs. active files)
1001      - new CPP options file OPENAD_OPTIONS.h
1002      - revert to genarr2d gradient check for hs94.1x64x5
1003      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
1004      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
1005    o tools/genmake2:
1006      - add option for an alternative Makefile (from Martin) where multiple
1007        source files are sent to TAF (instead of all in one file).
1008    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
1009      - code provided by Carsten Eden as an extension of ggl90
1010      - so far the code is turned on within ggl90 by setting a CPP-flag at
1011        compile time; a runtime flag implementation is not yet complete
1012      - tested in new verification experiment global_ocean.90x40x15.idemix
1013    o verification:
1014      - reduce length of the AD test run by half for experiments
1015        global_ocean.cs32x15 (std + thsice) and isomip
1016      - enable active file I/O for OpenAD, adjust verifications accordingly
1017      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
1018    o verification/testreport:
1019      - fix two non-POSIX sed statements so that there are no error messages
1020        on Mac OS X
1021      - replace hostname -s with hostname | sed 's/\..*$//'
1022    o model/src/seawater.F:
1023      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
1024        (following the matlab code), which would have avoided the bug caught
1025        by Matt (see below) in the first place
1026    o pkg/shelfice:
1027      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
1028        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
1029      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
1030        ice-shelf case (i.e., within surface level).
1031      - add config summary in shelfice_check.F
1032      - remove global variable recip_SHELFICElatentHeat and replace by a local
1033        variable recip_latentHeat
1034      - introduce diagnostics for friction velocity uStar (in case of
1035        SHELFICEuseGammaFrict)
1036      - change verification experiment isomip.htd:
1037        + start from pickup (as input_ad at nIter0=8640)
1038        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
1039        + test SHELFICEuseGammaFrict = .TRUE.
1040        + test SHELFICEadvDiffHeatFlux = .TRUE.
1041    o model/src:
1042      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
1043        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
1044        update output of experiments global_with_exf.yearly and isomip (all 6).
1045    o pkg/shelfice:
1046      - change setting of kTopC to also be zero where there is no ice-shelf.
1047      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1048        ice-shelf is.
1049      - first attempt to get RealFreshWaterFlux effects: for now, only without
1050        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1051    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1052      for thermodynamic calculations
1053      - because of divisions of the type 7/7 not exactly equal to 1, this change
1054        affects results of some verification experiments by up to 4 digits:
1055        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1056        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1057        adjoint: lab_sea, lab_sea.noseaicedyn
1058        -> updated
1059    
1060    checkpoint65i (2015/01/23)
1061    o model/src:
1062      - change units of frictionHeating field from W to W/m^2
1063      - fix bug in frictional heating from stratospheric drag in
1064        S/R ATM_PHYS_TENDENCY_APPLY_V
1065      - with synchronous time-stepping: move resetting to zero of frictionHeating
1066        field from load_fields_driver.F to thermodynamics.F ;
1067      - add diagnostics for frictional heating.
1068    o model/src & gmredi K3D:
1069      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1070      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1071      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1072        and name in pickup file).
1073      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1074    o model/src:
1075      - move (from ini_forcing.F) initialisation of all arrays in header file
1076        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1077        (since Nov 2012) with option selectAddFluid=1.
1078    o pkg/shelfice:
1079      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1080      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1081    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1082    o pkg/seaice: two new runtime parameters:
1083      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1084        long overdue
1085      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1086        parameterization of tensil stress for fast ice (does not do anything yet)
1087    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1088        for LSR: move checking overlaps out of JFNK-if-block
1089    o pkg/atm_phys:
1090      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1091        new S/R ATM_PHYS_DYN2PHYS.
1092      - fix level height for Linear Free-Surf case (to be consistent with
1093        fixed-in-time pressure levels).
1094    o pkg/mom_common (bottomdrag):
1095      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1096        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1097        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1098    o pkg/shelfice (u/v_drag):
1099      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1100      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1101        (now similar to shelfice_u_drag.F)
1102      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1103        from mom_vecinv.F (similar to mom_fluxform calls).
1104    o pkg/mom_common (bottomdrag):
1105      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1106      - add options for alternative discretisation of velocity norm in quadratic
1107        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1108        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1109        improves when averaging only the other component (e.g. vVel for U bottom
1110        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1111      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1112        friction (no-slip BC) thus getting the true distance from the bottom;
1113        off by default since this also reduces model stability (explicit bottom
1114        friction). Changes produce different machine truncation with linear-drag
1115        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1116        front_relax (bvp & mxl, 10 & 11 digits).
1117    o model/src & mom pkgs:
1118      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1119        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1120      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1121        just copy level Nr value to level Nr+1.
1122    o doc:
1123      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1124    o pkg/shelfice:
1125      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1126        SHELFICE.h: move array shelficemass to init_varia, initialise
1127        from array shelficemassinit, which is set in init_fixed and
1128        has option to be set from file; introduce array
1129        shelficeMassDynTend array, set thru file in init_fixed
1130      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1131        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1132        pkg/streamice
1133      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1134        SHELFICEMassStepping = .true.
1135      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1136    
1137    checkpoint65h (2014/12/17)
1138    o verification/global_ocean.90x40x15, global_ocean_ebm:
1139      - update to generic controls.
1140    o pkg/ctrl:
1141      - ctrl_map_ini_genarr.F: test for igen>0
1142      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1143      - move gentim2d part of ctrl_map_ini_genarr.F to
1144        new separate routine : ctrl_map_ini_gentim2d.F
1145      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1146        add time variable weights and cyclic controls (time mean,
1147        seasonal cycle, etc) capabilities to gentim2d
1148    o pkg/ecco:
1149      - move reading of error, conversion to weights from
1150        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1151    o global_oce_llc90, cs32:
1152      - activte sbo.
1153      - CTRL_SIZE.h : add maxCtrlProc.
1154      - activate the new genctrl capabilities.
1155      - update following reorganization of global_oce_input_fields.tar.gz  
1156    o pkg/ctrl/ctrl_ad_diff.list:
1157      - add missing ctrl_init_rec.f
1158    o tools/OAD_support/keepOriginal:
1159      - add ctrl_init_rec.F
1160    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1161      - avoid recomputations of xx_gentim2d_dummy.
1162    o momentum diagnostics:
1163      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1164        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1165    o pkg/seaice/seaice_lsr.F:
1166      - fix computation of BU/BV, make sure they are non-zero, only necessary
1167        for cubed sphere exchanges and SEAICE_OLx/y>0.
1168        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1169    o verification/global_ocean.cs32x15/input.seaice
1170      - add test for strong implicit coupling and restricted addtive Schwarz
1171        methods for LSR
1172      - update results/output.seaice.txt
1173    o verification/tutorial_global_oce_biogeo:
1174      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1175        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1176        update output_adm,_oadm,_tlm.txt
1177    o pkg/dic:
1178      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1179      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1180        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1181    o verification/tutorial_global_oce_biogeo:
1182      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1183        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1184        update output_adm,_oadm,_tlm.txt
1185    o eesupp/src:
1186      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1187        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1188    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1189      LSR (following Hutchings et al. 2004)
1190      - introduce zetaZ as a global variable (requires adjustments in
1191        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1192        in seaice_calc_viscosities.F
1193      - new flag SEAICEuseStrImpCpl (default off)
1194      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1195        momentum equations
1196      - JFNK-solver (preconditioner) adjusted to allow using this method
1197        (where it does not have any positive effect)
1198    o pkg/seaice
1199      - add overlap for restrictive additive Schwartz method also to LSR, but
1200        turn it off by default (because it only seems to work for non-cubed
1201        sphere/llc topologies)
1202    o pkg/autodiff
1203      - add extra exchanges in addummy_in_steppging also for mnc output
1204    o pkg/seaice:
1205      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1206        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1207    o pkg/obcs:
1208      - add option to specify domain-connected piece Id along OB though files
1209        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1210      - modify obcs_diag_balance.F to process each connected-part separately;
1211        exclude OB where Id = 0 but keep the full divergence there (-> constant
1212        Psi along this portion of OB and all inflow derived from grad(Phi))
1213      - add example of OB-conect files in verification/so_box_biogeo/input.
1214    o pkg/diagnostics:
1215      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1216      a) use non zero matrix element across OB and solve for Phi 1 grid point
1217         outside OB (i.e, where tracer OBCS are applied).
1218      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1219         velocity across OB, spread it uniformly along the OB in the RHS.
1220    
1221    checkpoint65g (2014/11/19)
1222    o pkg/diagnostcis:
1223      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1224    o pkg/my82,pp81,kl10:
1225      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1226        field diffKr as background diffusivity to set minimum diffusivity value.
1227    o pkg/seaice:
1228      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1229        Bouillon et al 2013)
1230      - add SEAICE_evpAlpha/Beta to namelist
1231      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1232        involve trivial re-ordering of divisions/multiplications that should not
1233        have any effects, but ... they do change the results of lab_sea.hb87 so
1234        that only 2 digits of agreement remain, in line with the general
1235        instability/fragility of the evp-code. For now, I do not care and just
1236        update the verification experiment
1237    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1238      - remove xx_genarr2d_numsmooth etc
1239      - use xx_genarr2d_preproc etc instead
1240      - carry out smooth_correl2D at initialization stage rather than during
1241        time stepping.
1242      - get smoothOpNb from xx_gentim2d_preproc
1243    o global_oce_cs32 :
1244      - add test of generic ecco capabilities.
1245    o pkg/exf/exf_getsurfacefluxes.F :
1246      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1247    o pkg/ctrl,ecco :
1248      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1249        is defined.
1250    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1251    o model/src:
1252      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1253        diffusivity (background) is specified but ignored.
1254    o verification:
1255      - in testreport, convert hostname to lower case for default output dir name
1256    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1257    o pkg/dic: add modifications from Hajoon:
1258      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1259      - light attenuation: add self-shading effect by climatological Chlorophyll
1260        (read from file).
1261    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1262        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1263    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1264        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1265        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1266        approach where CPP_OPTIONS.h includes an omnipotent
1267        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1268    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1269        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1270  o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF  o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
