4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where  checkpoint66h (2017/06/02)
8    ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.  o pkg/seaice:
9      - add new routines to compute stress tensor components and stress tensor
10        divergence to be reused in s/r seaice_lsr and s/r seaice_calc_lhs
11      - change names of diagnostics SIsigI/II (commonly used for invariants)
12        to SIsig1/sig2 (more common for principal components) to avoid confusion
13    o pkf/exf:
14      - add a stop if useRelativeWind with un-updated uwind/vwind (e.g., constant);
15        similarly, stop if rotateStressOnAgrid with constant wind-stress.
16    o pkg/seaice:
17      - remove (comment out) diagnostics SIuwind,SIvwind,SIfu,SIfv (duplicate of
18        EXFuwind,EXFvwind,oceTAUX,oceTAUY) and point them to their equivalent.
19      - add diagnostics of wind-stress over seaice (SItaux,SItauy) and seaice
20        fraction weighted wind stress over ocean+seaice (SIatmTx,SIatmTy).
21    o pkg/diagnostics:
22      - small piece of code to rename (old) diagnostics, when namelist is processed.
23    o model/src:
24      - new run-time param (useMin4hFacEdges) to select method for setting hFacW,S:
25        originally, set as minimum of adjacent hFacC factor ; now (new default)
26        computed from rSurfW,S and rLowW,S by applying same rules as for hFacC.
27        Only matters when useShelfIce=T with particular ice-shelf cavity geometry.
28    o pkg/seaice:
29      - add momemtum advection, off by default, still in test phase
30        most of the momentum advection code is adapted and reused from mom_vecinv
31    o pkg/mom_vecinv:
32      - pass these runtime flags:
33        selectVortScheme, highOrderVorticity, upwindVorticity, useJamartMomAdv
34        as formal parameters to s/r mom_vi_u/v_coriolis, mom_vi_u/v_coriolis_c4,
35        so that these routines can also be used in pkg/seaice.
36    
37    checkpoint66g (2017/04/24)
38    o model/src:
39      - more robust ordering of column thickness integral (=Sum_k(drF*hFac) )
40        to get same expression (regarding machine truncation) in different places
41        in ini_masks_etc.F (e.g., rSurfC,W,S is now exactly zero when it should).
42        Update forward output of experiments: global_ocean.cs32x15 (all 5 except
43        viscA4), isomip (x3), tutorial_global_oce_in_p & tutorial_plume_on_slope.
44    o pkg/shelfice:
45      - ALLOW_SHIFWFLX_CONTROL: move setting of maskSHI from shelfice_update_masks.F
46        to shelfice_init_fixed.F
47      - change S/R SHELFICE_UPDATE_MASKS to SHELFICE_INIT_DEPTHS (still called from
48        ini_masks_etc.F for now) to update ocean upper boundary position according
49        to ice-shelf topography (instead of directly updating hFacC).
50    o model/src:
51      - move call to CTRL_INIT & CTRL_ADMTLM from the middle to the bottom of
52        packages_init_fixed.F to allow other pkgs to set mask and weight fields.
53    
54    checkpoint66f (2017/04/06)
55    o model/src:
56      - add specific run-time param to select level of printed plot-field-maps,
57        set by default to debugLevel. Remove internal param "printDomain".
58    o pkg/seaice:
59      - add flag to add snow mass to seaiceMassC/U/V, the default is
60        SEAICEaddSnowMass=.FALSE., not to change previous results
61    o pkg/bling
62      - Bug fix in bling_production regarding unit conversion for diagnostics
63        being put in the wrong place
64    o model/src:
65      - add back recomputation of rSurfW & S to ensure consistent column thickness
66        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
67        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
68        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
69    o pkg/autodiff:
70      - clean-up "checkpoint.flow"
71    o pkg/rw (Contribution from Jody Klymak):
72        option to set mds file suffix as function of time in simulation:
73        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
74           to select file suffix format; by default (=0), use iteration number;
75        *) add simple routine to return file suffix according to rwSuffixType;
76        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
77           use new S/R to get file suffix, except for debug output file (diagFreq)
78           and pkgs offline & rbcs input files.
79    o pkg/rw:
80      - uniform processing of "I10" suffix across writing fld routines; used to
81        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
82        (similar to cg3d.F, cg3d_ex0.F)
83    o pkg/mom_vecinv:
84      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
85        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
86    o pkg/bling:
87      - Many small changes intended to clean the code.
88        Unnecessary ADJOINT_SAFEs removed ;
89        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
90        diagnostics added.
91    
92    checkpoint66e (2017/03/14)
93    o pkg/exf:
94      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
95        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
96        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
97        avoid any dynamic allocation ;
98      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
99        read-in ; add warning when file is read-in but not used within pkg/exf ;
100        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
101      - update exf_summary.F (print {FLD}RepCycle).
102    o verification/global_with_exf:
103      - switch on exf interpolation in AD test (just like the forward test)
104    o pkg/mom_vecinv:
105      - add storage directives to avoid recomputations within mom_vecinv.F
106        which were generating seg. fault with gfortran -devel
107    o pkg/ctrl, pkg/smooth:
108      - initialize array halos which were generating seg. fault with
109        gfortran -devel in adjoint mode
110    o pkg/exf:
111      - for each input field, enable to specify a field specific repeat-cycle
112        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
113    o verification/lab_sea:
114      - update AD results of primary test and noseaicedyn test after switching
115        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
116        check stays about the same.
117    o pkg/exf:
118      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
119      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
120    o pkg/bling, USE_EXFCO2 code:
121      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
122      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
123    o pkg/exf:
124      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
125      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
126        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
127        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
128      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
129        EXF_INIT_FLD) and update calls in exf_init_varia.F
130      - For now, for backward compatibility, keep a simplified version of S/Rs
131        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
132      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
133        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
134    o tools/genmake2:
135      - replace "bc -l" (only used once) by "expr" (already used).
136    o verification/global_ocean.cs32x15:
137      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
138        Note: exf setting (data.exf) can be compared to other exf secondary exp
139        "seaice" (kept with useCAL=T) which has same time dependent forcing.
140    
141    checkpoint66d (2017/02/13)
142    o pkg/exf:
143      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
144        early on (in packages_boot.F) to stress this change in pkg setting.
145      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
146    o model/src:
147      - move call to ecco_phys to end of time step; this may induce minor
148        cost function changes by shifting time averages by one time step
149        for some variables; this revision resulted in changed adjoint results
150        in MITgcm_contrib/verification_other/global_oce_cs32
151    o pkg/exf:
152      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
153        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
154        e.g. precip, are not available.
155    o pkg/flt:
156      - flt_init_varia.F: use pickupSuff if specified
157      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
158        intermediate, step towards completing pkg/exch2 support within pkg/flt;
159        ifdef DEVEL_FLT_EXCH2 then:
160        - flt_init_fixed.F: comment out stop
161        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
162        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
163        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
164        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
165    o tools/genmake2 & pkg/pkg_depend:
166      - define new type of pkg dependency rule ("=pkg_x"), less strict than
167        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
168        (-pkg_x in packages.conf).
169      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
170      - add "+cal" to dependency list of pkg/ecco (needed to compile).
171      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
172    o utils/matlab:
173      - adding ocean_basin routines for defining basin masks.
174    o pkg/exf:
175      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
176        arguments, allowing to check (and stop) if parameter setting of
177         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
178        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
179        for backward compatibility.
180      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
181        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
182    o pkg/bling (USE_EXFCO2 code):
183      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
184        by adding a call to S/R EXF_GETFFIELD_START.
185    o pkg/exf:
186      - allows to compile without pkg/cal (but disabled by current dependency
187        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
188        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
189        of {FLD}startdate1 & date2 ; consistency check not yet coded.
190    o verification/global_ocean.cs32x15:
191      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
192        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
193    o pkg/exf:
194      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
195        calculations); change FWD experiment global_ocean.cs32x15
196        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
197    o pkg/exf:
198      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
199         {FIELD}startdate to {FIELD}StartTime
200        Note: new name also fit better the content, i.e, a start time in second.
201    o eesupp/src:
202      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
203    o pkg/exf:
204      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
205        to allow to read-in Sensible & Latent Heat flux ;
206      - simplify pkg/exf main options:
207        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
208           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
209           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
210        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
211           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
212        3) improve options documentation in EXF_OPTIONS.h.
213    o pkg/ecco:
214      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
215        ecco_summary.F: add passive tracer cost functions to gencost;
216        m_ptracer and m_boxmean_ptracer
217    o pkg/ctrl:
218      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
219        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
220        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
221        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
222    o model/src:
223      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
224        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
225    o pkg/exf:
226      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
227        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
228    
229    checkpoint66c (2017/01/19)
230    o verification:
231      - add new option "-src" to testreport to only produce source code (*.f),
232        including taf output src code (if using '-adm'/'-tlm' option).
233    o pkg/exf:
234      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
235    o pkg/diagnostics:
236      - add run-time variable diagMdsDir to specify a subdirectory for
237        diagnostic output when mds is being used and mdsioLocalDir is not.
238    o pkg/mnc:
239      - mnc_utils.F: edit stop message
240    o pkg/autodiff:
241      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
242        add HAVE_SYSTEM bracket around system call to mkdir
243    o pkg/profiles:
244      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
245        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
246      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
247        add HAVE_SYSTEM bracket around system call to mkdir
248    o pkg/smooth:
249      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
250      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
251      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
252    o pkg/exf:
253      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
254        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
255        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
256      - summary: skip detailed field report if not used (empty file-name).
257    o tools/xmakedepend:
258      - In case line editor "ed" is missing, switch to "sed" command to clean-up
259        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
260    o pkg/exf:
261      - change definition of "hflux" input file to always include Short-Wave;
262        this is now consistent with hflux computation (if using bulk-formulae)
263        and hflux diagnostic & documentation (in EXF_FIELDS.h).
264    
265    checkpoint66b (2016/12/01)
266    o model & momentum pkgs:
267      - implement fully implicit bottom friction combined with implicit surf.
268        pressure, for now, only in hydrostic formulation:
269        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
270          and run with selectImplicitDrag=2 ;
271        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
272      - partial implicit time-stepping (bot. friction + vert. visc first, then
273        surf. press) corresponding to selectImplicitDrag=1 should be applicable
274        to NH formulation but not available until we solve for surf. pressure
275        increment (instead of full etaN).
276      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
277        with implicit vertical viscosity.
278    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
279      - this is a first version that includes many regularisations that may
280        not all be necessary, to be sorted out,
281      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
282      - change one verification experiment in seaice_itd to use and test new code
283      - seaice_growth: catch a case where the argument of log can be zero
284        or smaller (important for code stability)
285    o model/src:
286      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
287        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
288        similar A.X'=Y' system (with same matrix A) in subsequent calls;
289        switch based on errCode (In/Out) argument value; in calling routines,
290        initialise errCode before first call.
291    
292    checkpoint66a (2016/10/18)
293    o pkg/bling:
294      - BLING package now loads in atmospheric pCO2 file using exf package routines
295        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
296    o model/src & pkg/ptracers:
297      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
298        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
299        implicitDiffusion (respectively) are used (even without momImplVertAdv
300        or temp,salt,PTRACERS_ImplVertAdv).
301    o model/src & generic_advdiff:
302      - add parenthesis in main diagonal calculation of implicit vertical
303        diffusion matrix (impldiff.F & gad_implicit_r.F).
304        This affects results at machine truncation level; update output of many
305        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
306    o pkg/mom_commom & generic_advdiff:
307      - add deep atmosphere and anelastic scaling factor in implicit vertical
308        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
309    o model/src:
310      - remove few unnecessary temp array copies in solve_tridiagonal.F
311        & solve_pentadiagonal.F
312    
313    checkpoint65z (2016/09/28)
314    o pkg/seaice: fix multithreading for seaice_fgmres.F
315      - remove unecessary variables from common blocks
316      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
317        basis, that are stored in commom blocks (including integer variable i1)
318      - clean up code a little by removing commented lines that refer to
319        original code
320      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
321    o MITgcm manual:
322      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
323        preliminary documentation for generic controls (8.3; ctrl.tex),
324        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
325        ecco_costfunction.tex
326    o pkg/ecco:
327      - update and cleanup list of CCP options
328      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
329        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
330      - add checks that retired run-time options are not used, and in relation
331        to gencost_mask and gencost_errfile
332      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
333        gencost_nrecperiod
334      - fix m_eta computation for virtual salt flux case
335      - add m_horflux_vol case (selected via gencost_barfile) that computes
336        transports via cost_gencost_boxmean (gencost_flag=-3)
337      - use gencost_flag more systematically (i.e., avoid using gencost_name)
338        for code switches (aside from physical variable selection)
339    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
340      attempt appears to be a bit of a hack and my need some repair down the road
341    o pkg/exf:
342      - interpolation near South Pole: fix criteria on input field latitude.
343    o pkg/icefront & pkg/exf:
344      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
345        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
346    o pkg/exf:
347      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
348        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
349        (add suffix "_out" instead of a prefix); keep same record number as in
350        input file but always write record 1 first (to avoid a STOP in I/O S/R).
351        Change output file content by writing interpolated field before applying
352        land-sea mask (helpful for debug).
353      - 2 compon. vector interpolation with rotation: apply scaling factor on
354        each compon. (Eastward and Northward) just before rotation.
355    o pkg/bling:
356      - Cleaned package. Removed not needed code and comments.
357      - adjoint example now works
358        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
359    o pkg/ptracers:
360      - add Bruno Deremble's code to complete the linear surface correction
361        for tracer conservation;
362      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
363    
364    checkpoint65y (2016/07/29)
365    o pkg/debug (stats):
366      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
367        proc/thread mapping);
368      - fix Min & Max for case where 1 thread has only empty tiles;
369      - use RL variable to count number of wet grid points (with big domain,
370        can be too large to fit into integer*4).
371    o pkg/monitor:
372      - use RL variable to count number of wet grid points (but used only for del2)
373      - add new routine to compute Advective CFL within tracer time-stepping with
374        writing delayed until next monitor output.
375    o pkg/obcs:
376      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
377    o pkg/cal:
378      - calandar-dump: treat case myTime < timePhase in the same way as in
379        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
380    o pkg/dic & seaice:
381      - fix compilation of ocean component for coupled atm+ocn model with
382        seaice dynamics & dic.
383    
384    checkpoint65x (2016/06/11)
385    o add a license text file in main MITgcm tree.
386    o added pkg/bling:
387      - intermediate complexity biogeochemical model
388      - see bling_description.txt for details
389      - verification experiment is global_oce_biogeo_bling (for now, in
390        Contrib/verification_other/); tested daily on baudelaire with gfortran.
391      - add entry point in pkg/gchem for new pkg "bling".
392    o pkg/seaice: fix tensile stength computation
393      - replace global field tensileStrength by tensileStrFac
394      - tensileStrFac can be computed once in S/R seaice_init_varia
395      - fortunately that does not affect any verification results
396    
397    checkpoint65w (2016/05/12)
398    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
399         with ECCO_CTRL_DEPRECATED defined
400    o verification/global_ocean.cs32x15:
401      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
402        with "selectNHfreeSurf=1".
403    o model/src (non-hydrostatic free-surface):
404      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
405        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
406      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
407        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
408        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
409        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
410      - Update output (changes at machine truncation level) of verification exp:
411        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
412        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
413    o pkg/seaice: ITD code
414      - fix picking up from a single category model by initialising
415        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
416      - split a long warning message in seaice_check_pickup.F into two lines,
417        because NEC SX-ACE cannot deal with the long line.
418    o model/src:
419      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
420    o pkg/seaice:
421      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
422    o pkg/seaice:
423      - add basal stress as parameterisation for grounding ice
424        following Lemieux et al. (2015)
425      - turn on by setting new parameter SEAICEbasalDragK2 to a value
426        larger than 0. Lemieux et al. (2015) recommend 15.
427      - The adjoint complains with extra recomputations so there is also a
428        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
429        order to postpone the problem
430      - compile the new code in lab_sea
431    o verification/halfpipe_streamice:
432      - update both TAF and OpenAD adm output (machine truncation differences)
433    
434    checkpoint65v (2016/04/08)
435    o verification/advect_xz:
436      - increase overlap size from 3 to 4 and add new secondary test for PQM
437        advection scheme (with mono & wino limiter).
438      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
439    o model/src:
440      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
441        added phi0Ref) to set vertical axis origin and phiRef origin;
442        keep Ro_SeaLevel for backward compatibility (with a warning).
443       According to coordinate and fluid type:
444        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
445        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
446        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
447        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
448      - remove Ro_SeaLevel from ATM experiment parameter files;
449      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
450        complement; update output.txt (changes at machine truncation level).
451    o pkg/seaice/seaice_evp.F
452      - simplify computation of deltaZ and zetaZ to simple averaging following
453        Bouillon et al. (2013). This removes a lot of code, but also changes
454        verification experiment lab_sea.hb87 -> updated
455    
456    checkpoint65u (2016/03/14)
457    o pkg/generic_advdiff:
458      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
459        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
460        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
461        testing and not for actual use.
462    o model/src:
463      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
464        origin r = rF(1);
465      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
466        in EOS for height coordinate: enable to include NH Pressure or to use
467        more accurate pressure vertical profile; options not linked to EOS type
468        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
469      - start to implement variable gravity (along vertical): for now, only with
470        z-coords (not even z*).
471      - add Ideal Gas equation of state for height coordinate.
472      - update OpenAD output (affected at machine truncation level) of exp:
473        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
474    o pkg/exf:
475      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
476        of exf interpolation (before any rescaling, rotation or interpolation
477        to velocity point) for each field that gets loaded from file. This option
478        identically mimics the input file organization (e.g. record numbers in year
479        by year input files) besides the change in horizontal grid.
480      - add rotateStressOnAgrid run-time switch so that wind stress fields
481        can be provided on the A-grid in zonal/meridional direction and
482        rotated on the fly. This only applies to the case when the exf
483        interpolation is off and rotateStressOnAgrid is false by default.
484    o model/src:
485      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
486        it's also used with pkg/atm_phys) and add few more parameters (but still
487        inactive, src code yet to come)
488    
489    checkpoint65t (2016/02/10)
490    o pkg/atm_phys:
491      - from Ruth Geen: add optical depth dependence on CO2 concentration.
492    o model/src:
493      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
494        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
495        Update output of exp. deep_anelastic (changes at truncation level).
496    o tools:
497      - add a hack in "remove_comments_sed" (used only with TAF) for recent
498        version of OpenMPI (shipped with FC.23): comment out the new header
499        file "mpif-sizeof.h" which causes problems to TAF.
500    o pkg/seaice:
501      - change the termination criterion so that maxits (SEAICElinearIterMax)
502        has an effect
503      - unify iteration parameters for implicit solvers (JFNK and Picard)
504        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
505        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
506        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
507        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
508        SEAICEnonLinTol     replaces JFNKgamma_nonlin
509      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
510      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
511        use with SEAICEuseKrylov
512    o pkg/seaice/seaice_lsr.F
513        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
514        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
515        an effect.
516    o pkg/seaice: add two new parameters
517      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
518        parameter is not in any namelist)
519      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
520        a preconditioner for the non-linear Newton iteration of the JFNK
521        solver
522    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
523      affects some experiments at truncation level:
524      - global_ocean.cs32x15.icedyn (11 digits),
525      - global_ocean.cs32x15.seaice (11 digits),
526      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
527      - also update global_ocean.cs32x15 adjoint and tangent-linear results
528    o pkg/salt_plume & pkg/thsice:
529      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
530        connect salt_plume flux to ATM-OCN coupling pkgs interface:
531       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
532         export to coupler interface) even without compiling pkg/salt_plume ;
533       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
534         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
535    o pkg/dic:
536      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
537        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
538        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
539      - move also update with values from ATM-OCN Coupler in the same new S/R
540        (previously done in ocn_apply_import.F).
541    o tools/adjoint_options:
542      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
543        has been changed on Jan 14, 2016.
544    o pkg/ggl90:
545      - add alternative discretisation of vertical shear (off by default), to
546        compute the mean (@ grid-cell center) of vertical shear compon instead of
547        vertical shear of mean flow (@ grid-cell center).
548      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
549        results on adjacent faces of cubed-sphere grids; this fix the restart.
550    o pkg/atm_compon_interf:
551      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
552        pass last value, stored directly before export to CPL ;
553        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
554      - remove atmSLPr from pickup files (no longer needed for restart)
555    
556    checkpoint65s (2016/01/13)
557    o eesupp & genmake2:
558       - first check for Function ETIME and, if it fails, then check for subroutine
559         ETIME and consistent output; use the appropriate version in timers.F
560    o model/src:
561      - to check restart test, add option to apply EXCH to U,V earlier, just before
562        integr_continuity; turned off by default.
563    o pkg/dic:
564      - remove CPP option USE_ATMOSCO2 (not needed)
565    o tools/tst_2+2:
566      - try to ignore difference between +0 and -0 in binary file, causing test
567        to fail for no good reason.
568    o eesupp & genmake2:
569      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
570        but also check (in genmake2) that test runs and returns meaningful results.
571    o coupler pkgs:
572      Finish implementation of optionally-exchanged variable switches (started on
573       Nov 12) with addition of few more exchanged fields, including 2-way exchange
574       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
575       advection in OCN component; this requires sequential coupling.
576      coupler (pkg/atm_ocn_coupler):
577      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
578        routines (useful for debug).
579      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
580         flux, DIC fields) if corresponding switch is ON.
581      - add option to export RunOff to OCN (to use for DIC river input)
582      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
583      components (pkg/atm_ & ocn_compon_interf):
584      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
585        optionally exchanged fields; add a check & stop in cpl_readparms.F.
586        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
587        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
588      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
589        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
590      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
591      - hold in common block coupler optionally-exchanged variable switch
592        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
593      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
594        this is intended to replace the OCN cplFldtave.* output files (not updated
595        to contain new additional exchanged fields).
596    o pkg/dic:
597      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
598    o pkg/thsice:
599      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
600        and writing of thsice pickup files.
601    o pkg/atm_compon_interf:
602      - move all field individual export-call out of cpl_export_import_data.F
603        into new S/R ATM_EXPORT_FIELDS
604    o pkg/atm_compon_interf:
605      - store state variables (for now, only thSIce fields) just before beeing
606        exported (in cpl_export_import_data.F, like on ocean side) instead of from
607        atm_store_my_data.F like all exported fluxes.
608      - new version of pickup_cpl: write field names into meta file and read meta
609        file to find field postion in pickup. Also only write/read fields meeded for
610        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
611    o pkg/dic:
612      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
613    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
614        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
615        value can be from domain [0,1] to average between the two methods
616    o pkg/atm_phys:
617      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
618        hold fixed in time).
619    
620    checkpoint65r (2015/12/21)
621    o pkg/seaice:
622        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
623        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
624    o pkg/seaice:
625      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
626        when SEAICEscaleSurfStress=.TRUE.,
627      - apply areaW and areaS in S/R seaice_calc_lhs
628    o pkg/atm_phys:
629      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
630        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
631        for individual contribution (convection, LSC cond, radiation)
632      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
633        information); activated with: solar_exponent=0. and wv_exponent=-1.
634    o pkg/ggl90:
635      - within IDEMIX add upper limit for horizontal group velocity to
636        avoid instability problems in the explicit horizontal diffusion term for
637        long time steps or high resolution
638    o pkg/diagnostics:
639      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
640        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
641    o testreport:
642      - remove "-v" (verbose option) in default mpirun command.
643    o pkg/seaice/seaice_growth:
644      - catch potential division by zero in ITD code, does not change
645        verification results
646    o pkg/ecco:
647      - retire old codes to the Attic. The calls to retired functions are
648        left in a commented form in case they ever need to be re-activated.
649      - ecco_check.F: issue warning if any old CPP option is
650        defined that corresponds to retired codes -- then stop.
651    o pkg/atm_compon_interf:
652      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
653        coupler: use last time-step value instead of average over cplSendFrq_iter
654        time-step, similar to what is done for seaIceMass.
655        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
656    o eesupp & genmake2:
657      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
658        <= remove until a fix is found for some ifort version on ia32 machine.
659    o pkg/seaice/seaice_evp:
660      - refine residual computation
661    
662    checkpoint65q (2015/11/18)
663    o pkg/seaice/seaice_evp:
664      - fix residual computations so that they no longer affect the actual
665        simulation code
666      - fix seaice_readparams to be able to actually set new parameters
667        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
668    o model/src:
669      - fix wrong truncation (single prec) from "FLOAT" function in expressions
670        like: deltaT*FLOAT(myIter) when myIter is large:
671         a) replaced by DFLOAT (if not seen by TAF);
672         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
673    o pkg/aim_v23:
674      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
675        when pickupSuff is set ; do write rolling pickups + at the end of the run.
676    o pkg/atm_ocn_coupler + ocn_compon_interf:
677      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
678        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
679        add corresponding call in DO_OCEANIC_PHYS.
680    o coupler pkgs:
681      Start a new way to set-up optionally-exchanged variables (previously, only
682       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
683       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
684       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
685       compononent param default can be set accordingly).
686      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
687       but rather applies to a group a fields (going both ways like for DIC)
688       and corresponds to an option of coupling config.
689      coupler (pkg/atm_ocn_coupler):
690      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
691        and read namelist directly (without eessup S/R calls) instead of
692        in the very un-flexible old way, 1 param per line, in fixed order;
693      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
694        cleanly in CPL_CHECK_CPLCONFIG
695      - add new coupling-exchange selectors (some not yet active) including
696        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
697                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
698      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
699        component ; called directly from coupler.F, after comp. registrations;
700      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
701         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
702          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
703      components (pkg/atm_ & ocn_compon_interf):
704      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
705        CPP header file in all pkg source files.
706      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
707        ATM/OCN_CHECK_CPLCONFIG;
708      - add error-counter to track errors (e.g., in "data.cpl") and to stop
709        cleanly in ATM/OCN_CHECK_CPLCONFIG;
710      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
711        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
712        before PACKAGES_READPARMS;
713      verification/cpl_aim+ocn/:
714      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
715        "data.cpl" for coupler (in input_cpl).
716    o eesupp/inc:
717      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
718        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
719        to always cumulate tile local-sum in the same order (still uses
720        MPI_Allreduce like standard code).
721      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
722        that are now identical to standard version (in eesupp/inc).
723    o pkg/shelfice:
724      - add SHELFICETransCoeffTFile for initializing spatially varying
725        heat and salt transfer coefficients
726    o pkg/atm_compon_interf & ocn_compon_interf:
727      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
728        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
729      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
730    o pkg/atm_ocn_coupler:
731      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
732    o pkg/rbcs:
733      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
734        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
735      - add a short report (to STDOUT) about RBCS-mask settings.
736    
737    checkpoint65p (2015/10/23)
738    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
739        there is no adjoint test for EVP, we don't know what it does to the adjoint
740        solution, but at least there are no more recomputation warnings left
741    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
742        a chance of giving the same results as a fully converged VP (JFNK) solver
743    o tools/adjoint_options/adjoint_diva:
744      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
745    o pkg/streamice:
746      - spotted bug in streamice_driving_stress using dyG where should have been dxG
747    o pkg/exf:
748      - remove STOP statement that prevented to use wind or (wind-)stress
749        interpolation for constant-in-time forcing fields (wind/stress period = 0).
750    o pkg/seaice:
751      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
752        5 additionals 2D fields and 6 new store directives
753      - change logic in seaice_readparms.F: EVP code can now be turned on in
754        various ways, setting SEAICE_deltaTev is no longer required,
755        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
756        or SEAICEaEVPcoeff
757    o pkg/shelfice/shelfice_thermodynamics.F
758      - redefining uLoc/vLoc to u/v, instead of 2u/v
759    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
760      - this is an intermediate state of a truely converging EVP that has
761        the potential of outperforming implicit VP methods, I do not recommend
762        using it yet.
763      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
764        and all parameters are hardwired
765      - for convergence it still requires very smooth regularisations, that means,
766        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
767        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
768        specific averaging appears to be required, still subject to tuning
769      - still needs cleaning and I need to turn parameter into runtime parameters
770      - add code to compute and print residuals of iteration, compile with
771        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
772    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
773      that entered with r1.54 on Sep04, 2015, -> update results
774    
775    checkpoint65o (2015/09/14)
776    o pkg/mom_vecinv & mom_common:
777      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
778        called from there.
779      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
780        allows to use Vector-Invariant form in deep atmos and anelastic formulation
781    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
782      and Koenig-Beatty+Holland (2012)
783      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
784      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
785      - requires an extra input argument for S/R seaice_calc_viscosities
786      - tensileStrength's depth dependence is different from Itkin et al. (2015)
787        (to be changed and played with, for now exponential)
788    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
789      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
790        by AREA according to Connelly et al. (2004), JPO.
791      - For EVP and the LSR solver, the implicit part of the drag term is
792        the only non-zero term in the denominator when there is no ice (which
793        prevented running the model with zero ice-ocean drag). If
794        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
795        (or zero main diagonals BU/BV) which need to be caught. A practical
796        consequence is that for open water, the momentum equation reduce
797        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
798        they happen to be zero, often leading to a non-zero solution over
799        open water.
800    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
801        efficient EVP method.
802      - introduce area-weighted averages for e12 (analogously to
803        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
804        remain, but also changing the order of terms in the previous average
805        changed the results as much) -> update experiment
806      - add SEAICE_DELTA_SMOOTHREG code
807      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
808        TEM-code
809      - adjust loop bounds so that only required fields are computed
810      - add new averaging code for zetaZ/deltaZ (again similar to
811        seaice_calc_viscosities.F), inactive by default for now (will change
812        results again), but will replace old code eventually
813    o eesupp/src:
814      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
815        to always cumulate tile local-sum in the same order
816        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
817        Still uses MPI_Allreduce (like standard code) but on array of tiles
818        and should be faster than GLOBAL_SUM_SEND_RECV code.
819      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
820        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
821      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
822         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
823         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
824         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
825         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
826    
827    checkpoint65n (2015/07/29)
828    o pkg/thsice:
829      - add a warning when used with pkg/aim but without updating SST
830        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
831    o pkg/offline:
832      - change where Offline-Fields are loaded, from load_fields_driver.F to
833        directly within FORWARD_STEP, just after updating iter number and time;
834      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
835        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
836       These changes allow:
837        a) to recover exactly on-line results using deltaToffline=deltaTClock,
838        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
839        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
840        time-step, both with GM & KPP files and with recomputing these fields;
841        b) no needs to switch on staggerTimeStep anymore;
842        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
843      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
844    o pkg/offline:
845      - change (rarely used) offset-iteration parameter to an offset time (in s):
846        can easily recover previous offset-iter effect by setting offset-time
847        (offlineTimeOffset) to offset-iter x deltaToffline;
848      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
849        in KPP as part of surface buoyancy forcing) in offline run.
850      - fix ptracers KPP non-local term in the case where KPP is re-computed.
851    o OpenAD
852      - Adding preliminary ggl90 test to OpenAD verification.
853        Config. with ggl90 currently diverges after 64 time steps
854        so will need more work to become more stable
855      - Adding preliminary kpp test to OpenAD verification.
856        required small tweakes in kpp_routines.F
857      - Merge and update from Krishna Narayanan's contrib area:
858        * Add one variable for preliminary OpenAD DIVA
859        * Add replacement time-stepping for OpenAD DIVA
860        * genmake2 flag -diva (but only for OpenAD; preliminary)
861        * required modifs for OAD_support
862        successful preliminary test for tutorial_global_oce_biogeo/
863    o pkg/seaice:
864      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
865      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
866        delta with a smooth function in s/r seaice_calc_viscosity
867        (no effect on EVP)
868      - rename local suffix "sqr" into "sq" for more consistent variable names
869    o pkg/seaice:
870        add new parameter SEAICE_deltaMin that is used ***only***
871        for regularizing Delta (and nothing else, like the parameter
872        which is also used for all sorts of things SEAICE_EPS).
873        Defaults to SEAICE_EPS for backward compatibility only.
874    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
875        the wrong key by inialising it before use -> fixes a recomputation
876        problem but does not fix the gradient
877    o pkg/layers:
878      - move resetting of flux arrays to outside the iLa loop
879        (this caused layers_diapycnal to not work with more than one layer coord.)
880      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
881    o pkg/layers:
882      - remove from common block 3D layers fields (used to diagnose transport
883        in tracer coords) and declare them as local arrays in layers_calc.F
884    o pkg/seaice:
885      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
886        in lab_sea forward experiment (changes results -> updated)
887      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
888    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
889       computations; for SEAICE_VECTORIZE_LSR
890      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
891        sweep to the outside,
892      - remove store directives and add "CADJ loop sequential" directives
893        in analogy to model/src/solve_tridiagonal.F
894      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
895        boundaries to yield more readable code. This has also the charming side
896        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
897        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
898        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
899        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
900        an additional option)
901       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
902       but the adjoint gradients (which are affected by this change) still explode.
903    o coupler (atm & ocn _compon_interf):
904      - avoid using Exch2 IO mapping if not suitable.
905    
906    checkpoint65m (2015/06/15)
907    o pkg/layers:
908      - clean-up old parameters setting (from Sep 2012):
909        + remove old parameters setting from common block (declared locally);
910        + stop if any old parameter is mixed with new parameters;
911        + check for valid or consistent parameter setting (e.g., layers_name)
912      - check that layers_bounds for Pot.Density are in the right range;
913        this is supposed to catch un-updated setting after recently shifting
914        potential density field "prho" by -1000 (now in "sigma" scale).
915    o pkg/layers:
916      - Added missing call to layers_fill for keeping track of tottend in
917        pkg/diagnostics/diagnostics_fill_state.F
918    o pkg/layers:
919      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
920        of diapycnal fluxes
921    o pkg/layers:
922      - reverted changes to interpolation to previous treatment; there
923        was never actually a problem
924    o pkg/layers:
925      - fix interpolation of layers tracers in the presence of partial cells
926      - add lots of new functionality to compute water mass transformation
927        (enabled by CPP flag LAYERS_THERMODYNAMICS)
928      - add new calls from main code (diags_oceanic_surf_flux.F,
929        thermodynamics.F, impldiff.F) and gad to save the necessary fields
930        for layers_thermodynamics calculations
931    o pkg/ptracers:
932      - add capability of stepping a passive tracer forward without advection
933        by setting PTRACERS_advScheme to 0.
934    o pkg/diagnostics:
935      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
936    o pkg/layers:
937      - shift potential density field "prho" by -1000 for density layer averaging so
938        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
939        Note that density bin boundaries (layers_bounds in data.layers) have
940        to be set accordingly (i.e., shifted, in sigma scale).
941    o pkg/layers:
942      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
943      - fix calculation of layer non-weighted velocity and layer probability
944      - add diagnostics for pot.density used for layer averaging
945    o pkg/seaice:
946      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
947        positiveness, modify a few comments and improve variable names,
948      - the changed computation of deltaC affects most seaice-related
949        experiments at the truncation level.
950        seaice_itd.thermo is affected by far the most, with
951        only 7 digits of agreement remaining; update experiments.
952    
953    checkpoint65l (2015/05/04)
954    o pkg/shelfice:
955      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
956        factor drKp1 to zero where it is negative (ie. do not use
957        SHELFICEBoundaryLayer if hFacC>1)
958      - the same for factor drLoc in shelfice_forcing.F
959    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
960        with modules in ptracers, when using testreport option "-small_f"
961    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
962      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
963    o verification/testreport
964      - add new option -small_f
965        with this option testreport first makes the target small_f (*.f files)
966        before running make (all). This is useful for explicit inlining when
967        all sources need to be full available.
968    o pkg/exf/exf_interp.F:
969        remove previous changes related to reverse (decreasing) input grids latitude
970    
971    checkpoint65k (2015/04/01)
972    o pkg/ecco:
973        fix missing cosphi initialization; use eccoiter in place of optimcycle;
974        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
975        instead of active read/write
976    o pkg/ctrl:
977        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
978        instead of active read/write.
979    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
980        return if .NOT.useAUTODIFF
981    o pkg/seaice: add CPP brackets (cost function related).
982    o model/src:
983        add useAUTODIFF run time switch.
984    o pkg/exf/exf_interp.F:
985        add code to allow input grids with latitude starting in the north (i.e. when
986        j=1 corresponds to northern edge of field); modify global_with_exf to test
987        this feature.
988    o verification/testreport:
989      - replace "grep -A3" with POSIX conformal sed command, because there are
990        implementations of grep that cannot do contextual searches
991      - replace "cat -n" by "nl" (two occurrences), because not all implementations
992        of "cat" have the option "-n"
993    o model/src:
994        add new file gsw_teos10.F that contains 3 functions, more or less a copy
995        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
996        convert from conservative to potential temperature. For now they are not
997        called anywhere.
998    o pkg/ggl90: make "useIDEMIX" useful
999      - re-organize code in s/r ggl90_calc a little to move computations that
1000        are different for idemix into separate loops (changes verification
1001        experiment idemix at truncation level, 12 digits remain -> updated)
1002      - requires 2 new 2D fields KappaM, verticalShear
1003      - make hFacI and recip_hFacI local 3D variables that are passed to
1004        s/r ggl90_idemix
1005      - fix and improve some comments
1006    
1007    checkpoint65j (2015/02/25)
1008    o pkg/openad
1009      - synchronize seawater.F with version in model/src: replace routine
1010        body of sw_temp by calling sw_ptmp and fix/add a few comments.
1011    o pkg/mnc:
1012      - change default value of pickup_read/write_mnc params to FALSE
1013        (since few features are missing in reading MNC pickup files).
1014    o model/src:
1015      - change default (background) vertical diffusivity for salt to be the
1016        temperature (background) vertical diffusivity.
1017      - change background vertical diffusivity in vertical mixing pkgs ggl90,
1018        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
1019        This makes ptracers default diffusivity (that uses salt diffKr) more
1020        consistent with vertical mixing schemes.
1021    o verification/testreport:
1022      - fix typo in "-pcls" option ;
1023      - put temp files in /tmp (instead of in local dir)
1024      - add option "-ncad" to use genmake2 new option "-nocat4ad"
1025      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
1026    o pkg/ggl90 (idemix code):
1027      - apply few fixes ; add some missing "_d 0" ; update output of exp.
1028        global_ocean.90x40x15.idemix
1029    o OpenAD
1030      - enable active file I/O and begin removal of work-around code
1031        for OpenAD for handling control variables (memory vs. active files)
1032      - new CPP options file OPENAD_OPTIONS.h
1033      - revert to genarr2d gradient check for hs94.1x64x5
1034      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
1035      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
1036    o tools/genmake2:
1037      - add option for an alternative Makefile (from Martin) where multiple
1038        source files are sent to TAF (instead of all in one file).
1039    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
1040      - code provided by Carsten Eden as an extension of ggl90
1041      - so far the code is turned on within ggl90 by setting a CPP-flag at
1042        compile time; a runtime flag implementation is not yet complete
1043      - tested in new verification experiment global_ocean.90x40x15.idemix
1044    o verification:
1045      - reduce length of the AD test run by half for experiments
1046        global_ocean.cs32x15 (std + thsice) and isomip
1047      - enable active file I/O for OpenAD, adjust verifications accordingly
1048      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
1049    o verification/testreport:
1050      - fix two non-POSIX sed statements so that there are no error messages
1051        on Mac OS X
1052      - replace hostname -s with hostname | sed 's/\..*$//'
1053    o model/src/seawater.F:
1054      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
1055        (following the matlab code), which would have avoided the bug caught
1056        by Matt (see below) in the first place
1057    o pkg/shelfice:
1058      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
1059        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
1060      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
1061        ice-shelf case (i.e., within surface level).
1062      - add config summary in shelfice_check.F
1063      - remove global variable recip_SHELFICElatentHeat and replace by a local
1064        variable recip_latentHeat
1065      - introduce diagnostics for friction velocity uStar (in case of
1066        SHELFICEuseGammaFrict)
1067      - change verification experiment isomip.htd:
1068        + start from pickup (as input_ad at nIter0=8640)
1069        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
1070        + test SHELFICEuseGammaFrict = .TRUE.
1071        + test SHELFICEadvDiffHeatFlux = .TRUE.
1072    o model/src:
1073      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
1074        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
1075        update output of experiments global_with_exf.yearly and isomip (all 6).
1076    o pkg/shelfice:
1077      - change setting of kTopC to also be zero where there is no ice-shelf.
1078      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1079        ice-shelf is.
1080      - first attempt to get RealFreshWaterFlux effects: for now, only without
1081        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1082    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1083      for thermodynamic calculations
1084      - because of divisions of the type 7/7 not exactly equal to 1, this change
1085        affects results of some verification experiments by up to 4 digits:
1086        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1087        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1088        adjoint: lab_sea, lab_sea.noseaicedyn
1089        -> updated
1090    
1091    checkpoint65i (2015/01/23)
1092    o model/src:
1093      - change units of frictionHeating field from W to W/m^2
1094      - fix bug in frictional heating from stratospheric drag in
1095        S/R ATM_PHYS_TENDENCY_APPLY_V
1096      - with synchronous time-stepping: move resetting to zero of frictionHeating
1097        field from load_fields_driver.F to thermodynamics.F ;
1098      - add diagnostics for frictional heating.
1099    o model/src & gmredi K3D:
1100      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1101      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1102      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1103        and name in pickup file).
1104      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1105    o model/src:
1106      - move (from ini_forcing.F) initialisation of all arrays in header file
1107        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1108        (since Nov 2012) with option selectAddFluid=1.
1109    o pkg/shelfice:
1110      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1111      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1112    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1113    o pkg/seaice: two new runtime parameters:
1114      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1115        long overdue
1116      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1117        parameterization of tensil stress for fast ice (does not do anything yet)
1118    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1119        for LSR: move checking overlaps out of JFNK-if-block
1120    o pkg/atm_phys:
1121      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1122        new S/R ATM_PHYS_DYN2PHYS.
1123      - fix level height for Linear Free-Surf case (to be consistent with
1124        fixed-in-time pressure levels).
1125    o pkg/mom_common (bottomdrag):
1126      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1127        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1128        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1129    o pkg/shelfice (u/v_drag):
1130      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1131      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1132        (now similar to shelfice_u_drag.F)
1133      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1134        from mom_vecinv.F (similar to mom_fluxform calls).
1135    o pkg/mom_common (bottomdrag):
1136      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1137      - add options for alternative discretisation of velocity norm in quadratic
1138        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1139        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1140        improves when averaging only the other component (e.g. vVel for U bottom
1141        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1142      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1143        friction (no-slip BC) thus getting the true distance from the bottom;
1144        off by default since this also reduces model stability (explicit bottom
1145        friction). Changes produce different machine truncation with linear-drag
1146        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1147        front_relax (bvp & mxl, 10 & 11 digits).
1148    o model/src & mom pkgs:
1149      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1150        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1151      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1152        just copy level Nr value to level Nr+1.
1153    o doc:
1154      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1155    o pkg/shelfice:
1156      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1157        SHELFICE.h: move array shelficemass to init_varia, initialise
1158        from array shelficemassinit, which is set in init_fixed and
1159        has option to be set from file; introduce array
1160        shelficeMassDynTend array, set thru file in init_fixed
1161      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1162        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1163        pkg/streamice
1164      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1165        SHELFICEMassStepping = .true.
1166      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1167    
1168    checkpoint65h (2014/12/17)
1169    o verification/global_ocean.90x40x15, global_ocean_ebm:
1170      - update to generic controls.
1171    o pkg/ctrl:
1172      - ctrl_map_ini_genarr.F: test for igen>0
1173      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1174      - move gentim2d part of ctrl_map_ini_genarr.F to
1175        new separate routine : ctrl_map_ini_gentim2d.F
1176      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1177        add time variable weights and cyclic controls (time mean,
1178        seasonal cycle, etc) capabilities to gentim2d
1179    o pkg/ecco:
1180      - move reading of error, conversion to weights from
1181        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1182    o global_oce_llc90, cs32:
1183      - activte sbo.
1184      - CTRL_SIZE.h : add maxCtrlProc.
1185      - activate the new genctrl capabilities.
1186      - update following reorganization of global_oce_input_fields.tar.gz  
1187    o pkg/ctrl/ctrl_ad_diff.list:
1188      - add missing ctrl_init_rec.f
1189    o tools/OAD_support/keepOriginal:
1190      - add ctrl_init_rec.F
1191    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1192      - avoid recomputations of xx_gentim2d_dummy.
1193    o momentum diagnostics:
1194      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1195        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1196    o pkg/seaice/seaice_lsr.F:
1197      - fix computation of BU/BV, make sure they are non-zero, only necessary
1198        for cubed sphere exchanges and SEAICE_OLx/y>0.
1199        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1200    o verification/global_ocean.cs32x15/input.seaice
1201      - add test for strong implicit coupling and restricted addtive Schwarz
1202        methods for LSR
1203      - update results/output.seaice.txt
1204    o verification/tutorial_global_oce_biogeo:
1205      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1206        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1207        update output_adm,_oadm,_tlm.txt
1208    o pkg/dic:
1209      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1210      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1211        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1212    o verification/tutorial_global_oce_biogeo:
1213      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1214        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1215        update output_adm,_oadm,_tlm.txt
1216    o eesupp/src:
1217      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1218        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1219    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1220      LSR (following Hutchings et al. 2004)
1221      - introduce zetaZ as a global variable (requires adjustments in
1222        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1223        in seaice_calc_viscosities.F
1224      - new flag SEAICEuseStrImpCpl (default off)
1225      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1226        momentum equations
1227      - JFNK-solver (preconditioner) adjusted to allow using this method
1228        (where it does not have any positive effect)
1229    o pkg/seaice
1230      - add overlap for restrictive additive Schwartz method also to LSR, but
1231        turn it off by default (because it only seems to work for non-cubed
1232        sphere/llc topologies)
1233    o pkg/autodiff
1234      - add extra exchanges in addummy_in_steppging also for mnc output
1235    o pkg/seaice:
1236      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1237        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1238    o pkg/obcs:
1239      - add option to specify domain-connected piece Id along OB though files
1240        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1241      - modify obcs_diag_balance.F to process each connected-part separately;
1242        exclude OB where Id = 0 but keep the full divergence there (-> constant
1243        Psi along this portion of OB and all inflow derived from grad(Phi))
1244      - add example of OB-conect files in verification/so_box_biogeo/input.
1245    o pkg/diagnostics:
1246      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1247      a) use non zero matrix element across OB and solve for Phi 1 grid point
1248         outside OB (i.e, where tracer OBCS are applied).
1249      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1250         velocity across OB, spread it uniformly along the OB in the RHS.
1251    
1252    checkpoint65g (2014/11/19)
1253    o pkg/diagnostcis:
1254      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1255    o pkg/my82,pp81,kl10:
1256      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1257        field diffKr as background diffusivity to set minimum diffusivity value.
1258    o pkg/seaice:
1259      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1260        Bouillon et al 2013)
1261      - add SEAICE_evpAlpha/Beta to namelist
1262      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1263        involve trivial re-ordering of divisions/multiplications that should not
1264        have any effects, but ... they do change the results of lab_sea.hb87 so
1265        that only 2 digits of agreement remain, in line with the general
1266        instability/fragility of the evp-code. For now, I do not care and just
1267        update the verification experiment
1268    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1269      - remove xx_genarr2d_numsmooth etc
1270      - use xx_genarr2d_preproc etc instead
1271      - carry out smooth_correl2D at initialization stage rather than during
1272        time stepping.
1273      - get smoothOpNb from xx_gentim2d_preproc
1274    o global_oce_cs32 :
1275      - add test of generic ecco capabilities.
1276    o pkg/exf/exf_getsurfacefluxes.F :
1277      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1278    o pkg/ctrl,ecco :
1279      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1280        is defined.
1281    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1282    o model/src:
1283      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1284        diffusivity (background) is specified but ignored.
1285    o verification:
1286      - in testreport, convert hostname to lower case for default output dir name
1287    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1288    o pkg/dic: add modifications from Hajoon:
1289      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1290      - light attenuation: add self-shading effect by climatological Chlorophyll
1291        (read from file).
1292    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1293        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1294    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1295        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1296        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1297        approach where CPP_OPTIONS.h includes an omnipotent
1298        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1299    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1300        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1301  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
