4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8      - prevent JFNK and KRYLOV solvers from trying to reduce a residual of 0
9      - add the option to compute no-slip du/dy, dv/dx (i.e.
10        the offdiagonal strain rate e12) by a second order approximation
11        on the boundary; works only with JFNK, KRYLOV, or EVP solvers, because
12        it is too messy to implement for the implicit LSR matrix.
13        SEAICE_2ndOrderBC = .FALSE. by default
14    
15    checkpoint66h (2017/06/02)
16    o pkg/seaice:
17      - add new routines to compute stress tensor components and stress tensor
18        divergence to be reused in s/r seaice_lsr and s/r seaice_calc_lhs
19      - change names of diagnostics SIsigI/II (commonly used for invariants)
20        to SIsig1/sig2 (more common for principal components) to avoid confusion
21    o pkf/exf:
22      - add a stop if useRelativeWind with un-updated uwind/vwind (e.g., constant);
23        similarly, stop if rotateStressOnAgrid with constant wind-stress.
24    o pkg/seaice:
25      - remove (comment out) diagnostics SIuwind,SIvwind,SIfu,SIfv (duplicate of
26        EXFuwind,EXFvwind,oceTAUX,oceTAUY) and point them to their equivalent.
27      - add diagnostics of wind-stress over seaice (SItaux,SItauy) and seaice
28        fraction weighted wind stress over ocean+seaice (SIatmTx,SIatmTy).
29    o pkg/diagnostics:
30      - small piece of code to rename (old) diagnostics, when namelist is processed.
31    o model/src:
32      - new run-time param (useMin4hFacEdges) to select method for setting hFacW,S:
33        originally, set as minimum of adjacent hFacC factor ; now (new default)
34        computed from rSurfW,S and rLowW,S by applying same rules as for hFacC.
35        Only matters when useShelfIce=T with particular ice-shelf cavity geometry.
36    o pkg/seaice:
37      - add momemtum advection, off by default, still in test phase
38        most of the momentum advection code is adapted and reused from mom_vecinv
39    o pkg/mom_vecinv:
40      - pass these runtime flags:
41        selectVortScheme, highOrderVorticity, upwindVorticity, useJamartMomAdv
42        as formal parameters to s/r mom_vi_u/v_coriolis, mom_vi_u/v_coriolis_c4,
43        so that these routines can also be used in pkg/seaice.
44    
45    checkpoint66g (2017/04/24)
46    o model/src:
47      - more robust ordering of column thickness integral (=Sum_k(drF*hFac) )
48        to get same expression (regarding machine truncation) in different places
49        in ini_masks_etc.F (e.g., rSurfC,W,S is now exactly zero when it should).
50        Update forward output of experiments: global_ocean.cs32x15 (all 5 except
51        viscA4), isomip (x3), tutorial_global_oce_in_p & tutorial_plume_on_slope.
52    o pkg/shelfice:
53      - ALLOW_SHIFWFLX_CONTROL: move setting of maskSHI from shelfice_update_masks.F
54        to shelfice_init_fixed.F
55      - change S/R SHELFICE_UPDATE_MASKS to SHELFICE_INIT_DEPTHS (still called from
56        ini_masks_etc.F for now) to update ocean upper boundary position according
57        to ice-shelf topography (instead of directly updating hFacC).
58    o model/src:
59      - move call to CTRL_INIT & CTRL_ADMTLM from the middle to the bottom of
60        packages_init_fixed.F to allow other pkgs to set mask and weight fields.
61    
62    checkpoint66f (2017/04/06)
63    o model/src:
64      - add specific run-time param to select level of printed plot-field-maps,
65        set by default to debugLevel. Remove internal param "printDomain".
66    o pkg/seaice:
67      - add flag to add snow mass to seaiceMassC/U/V, the default is
68        SEAICEaddSnowMass=.FALSE., not to change previous results
69    o pkg/bling
70      - Bug fix in bling_production regarding unit conversion for diagnostics
71        being put in the wrong place
72    o model/src:
73      - add back recomputation of rSurfW & S to ensure consistent column thickness
74        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
75        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
76        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
77    o pkg/autodiff:
78      - clean-up "checkpoint.flow"
79    o pkg/rw (Contribution from Jody Klymak):
80        option to set mds file suffix as function of time in simulation:
81        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
82           to select file suffix format; by default (=0), use iteration number;
83        *) add simple routine to return file suffix according to rwSuffixType;
84        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
85           use new S/R to get file suffix, except for debug output file (diagFreq)
86           and pkgs offline & rbcs input files.
87    o pkg/rw:
88      - uniform processing of "I10" suffix across writing fld routines; used to
89        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
90        (similar to cg3d.F, cg3d_ex0.F)
91    o pkg/mom_vecinv:
92      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
93        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
94    o pkg/bling:
95      - Many small changes intended to clean the code.
96        Unnecessary ADJOINT_SAFEs removed ;
97        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
98        diagnostics added.
99    
100    checkpoint66e (2017/03/14)
101    o pkg/exf:
102      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
103        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
104        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
105        avoid any dynamic allocation ;
106      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
107        read-in ; add warning when file is read-in but not used within pkg/exf ;
108        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
109      - update exf_summary.F (print {FLD}RepCycle).
110    o verification/global_with_exf:
111      - switch on exf interpolation in AD test (just like the forward test)
112    o pkg/mom_vecinv:
113      - add storage directives to avoid recomputations within mom_vecinv.F
114        which were generating seg. fault with gfortran -devel
115    o pkg/ctrl, pkg/smooth:
116      - initialize array halos which were generating seg. fault with
117        gfortran -devel in adjoint mode
118    o pkg/exf:
119      - for each input field, enable to specify a field specific repeat-cycle
120        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
121    o verification/lab_sea:
122      - update AD results of primary test and noseaicedyn test after switching
123        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
124        check stays about the same.
125    o pkg/exf:
126      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
127      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
128    o pkg/bling, USE_EXFCO2 code:
129      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
130      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
131    o pkg/exf:
132      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
133      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
134        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
135        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
136      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
137        EXF_INIT_FLD) and update calls in exf_init_varia.F
138      - For now, for backward compatibility, keep a simplified version of S/Rs
139        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
140      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
141        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
142    o tools/genmake2:
143      - replace "bc -l" (only used once) by "expr" (already used).
144    o verification/global_ocean.cs32x15:
145      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
146        Note: exf setting (data.exf) can be compared to other exf secondary exp
147        "seaice" (kept with useCAL=T) which has same time dependent forcing.
148    
149    checkpoint66d (2017/02/13)
150    o pkg/exf:
151      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
152        early on (in packages_boot.F) to stress this change in pkg setting.
153      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
154    o model/src:
155      - move call to ecco_phys to end of time step; this may induce minor
156        cost function changes by shifting time averages by one time step
157        for some variables; this revision resulted in changed adjoint results
158        in MITgcm_contrib/verification_other/global_oce_cs32
159    o pkg/exf:
160      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
161        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
162        e.g. precip, are not available.
163    o pkg/flt:
164      - flt_init_varia.F: use pickupSuff if specified
165      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
166        intermediate, step towards completing pkg/exch2 support within pkg/flt;
167        ifdef DEVEL_FLT_EXCH2 then:
168        - flt_init_fixed.F: comment out stop
169        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
170        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
171        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
172        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
173    o tools/genmake2 & pkg/pkg_depend:
174      - define new type of pkg dependency rule ("=pkg_x"), less strict than
175        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
176        (-pkg_x in packages.conf).
177      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
178      - add "+cal" to dependency list of pkg/ecco (needed to compile).
179      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
180    o utils/matlab:
181      - adding ocean_basin routines for defining basin masks.
182    o pkg/exf:
183      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
184        arguments, allowing to check (and stop) if parameter setting of
185         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
186        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
187        for backward compatibility.
188      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
189        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
190    o pkg/bling (USE_EXFCO2 code):
191      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
192        by adding a call to S/R EXF_GETFFIELD_START.
193    o pkg/exf:
194      - allows to compile without pkg/cal (but disabled by current dependency
195        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
196        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
197        of {FLD}startdate1 & date2 ; consistency check not yet coded.
198    o verification/global_ocean.cs32x15:
199      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
200        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
201    o pkg/exf:
202      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
203        calculations); change FWD experiment global_ocean.cs32x15
204        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
205    o pkg/exf:
206      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
207         {FIELD}startdate to {FIELD}StartTime
208        Note: new name also fit better the content, i.e, a start time in second.
209    o eesupp/src:
210      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
211    o pkg/exf:
212      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
213        to allow to read-in Sensible & Latent Heat flux ;
214      - simplify pkg/exf main options:
215        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
216           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
217           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
218        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
219           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
220        3) improve options documentation in EXF_OPTIONS.h.
221    o pkg/ecco:
222      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
223        ecco_summary.F: add passive tracer cost functions to gencost;
224        m_ptracer and m_boxmean_ptracer
225    o pkg/ctrl:
226      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
227        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
228        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
229        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
230    o model/src:
231      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
232        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
233    o pkg/exf:
234      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
235        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
236    
237    checkpoint66c (2017/01/19)
238    o verification:
239      - add new option "-src" to testreport to only produce source code (*.f),
240        including taf output src code (if using '-adm'/'-tlm' option).
241    o pkg/exf:
242      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
243    o pkg/diagnostics:
244      - add run-time variable diagMdsDir to specify a subdirectory for
245        diagnostic output when mds is being used and mdsioLocalDir is not.
246    o pkg/mnc:
247      - mnc_utils.F: edit stop message
248    o pkg/autodiff:
249      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
250        add HAVE_SYSTEM bracket around system call to mkdir
251    o pkg/profiles:
252      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
253        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
254      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
255        add HAVE_SYSTEM bracket around system call to mkdir
256    o pkg/smooth:
257      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
258      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
259      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
260    o pkg/exf:
261      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
262        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
263        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
264      - summary: skip detailed field report if not used (empty file-name).
265    o tools/xmakedepend:
266      - In case line editor "ed" is missing, switch to "sed" command to clean-up
267        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
268    o pkg/exf:
269      - change definition of "hflux" input file to always include Short-Wave;
270        this is now consistent with hflux computation (if using bulk-formulae)
271        and hflux diagnostic & documentation (in EXF_FIELDS.h).
272    
273    checkpoint66b (2016/12/01)
274    o model & momentum pkgs:
275      - implement fully implicit bottom friction combined with implicit surf.
276        pressure, for now, only in hydrostic formulation:
277        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
278          and run with selectImplicitDrag=2 ;
279        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
280      - partial implicit time-stepping (bot. friction + vert. visc first, then
281        surf. press) corresponding to selectImplicitDrag=1 should be applicable
282        to NH formulation but not available until we solve for surf. pressure
283        increment (instead of full etaN).
284      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
285        with implicit vertical viscosity.
286    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
287      - this is a first version that includes many regularisations that may
288        not all be necessary, to be sorted out,
289      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
290      - change one verification experiment in seaice_itd to use and test new code
291      - seaice_growth: catch a case where the argument of log can be zero
292        or smaller (important for code stability)
293    o model/src:
294      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
295        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
296        similar A.X'=Y' system (with same matrix A) in subsequent calls;
297        switch based on errCode (In/Out) argument value; in calling routines,
298        initialise errCode before first call.
299    
300    checkpoint66a (2016/10/18)
301    o pkg/bling:
302      - BLING package now loads in atmospheric pCO2 file using exf package routines
303        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
304    o model/src & pkg/ptracers:
305      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
306        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
307        implicitDiffusion (respectively) are used (even without momImplVertAdv
308        or temp,salt,PTRACERS_ImplVertAdv).
309    o model/src & generic_advdiff:
310      - add parenthesis in main diagonal calculation of implicit vertical
311        diffusion matrix (impldiff.F & gad_implicit_r.F).
312        This affects results at machine truncation level; update output of many
313        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
314    o pkg/mom_commom & generic_advdiff:
315      - add deep atmosphere and anelastic scaling factor in implicit vertical
316        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
317    o model/src:
318      - remove few unnecessary temp array copies in solve_tridiagonal.F
319        & solve_pentadiagonal.F
320    
321    checkpoint65z (2016/09/28)
322    o pkg/seaice: fix multithreading for seaice_fgmres.F
323      - remove unecessary variables from common blocks
324      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
325        basis, that are stored in commom blocks (including integer variable i1)
326      - clean up code a little by removing commented lines that refer to
327        original code
328      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
329    o MITgcm manual:
330      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
331        preliminary documentation for generic controls (8.3; ctrl.tex),
332        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
333        ecco_costfunction.tex
334    o pkg/ecco:
335      - update and cleanup list of CCP options
336      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
337        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
338      - add checks that retired run-time options are not used, and in relation
339        to gencost_mask and gencost_errfile
340      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
341        gencost_nrecperiod
342      - fix m_eta computation for virtual salt flux case
343      - add m_horflux_vol case (selected via gencost_barfile) that computes
344        transports via cost_gencost_boxmean (gencost_flag=-3)
345      - use gencost_flag more systematically (i.e., avoid using gencost_name)
346        for code switches (aside from physical variable selection)
347    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
348      attempt appears to be a bit of a hack and my need some repair down the road
349    o pkg/exf:
350      - interpolation near South Pole: fix criteria on input field latitude.
351    o pkg/icefront & pkg/exf:
352      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
353        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
354    o pkg/exf:
355      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
356        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
357        (add suffix "_out" instead of a prefix); keep same record number as in
358        input file but always write record 1 first (to avoid a STOP in I/O S/R).
359        Change output file content by writing interpolated field before applying
360        land-sea mask (helpful for debug).
361      - 2 compon. vector interpolation with rotation: apply scaling factor on
362        each compon. (Eastward and Northward) just before rotation.
363    o pkg/bling:
364      - Cleaned package. Removed not needed code and comments.
365      - adjoint example now works
366        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
367    o pkg/ptracers:
368      - add Bruno Deremble's code to complete the linear surface correction
369        for tracer conservation;
370      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
371    
372    checkpoint65y (2016/07/29)
373    o pkg/debug (stats):
374      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
375        proc/thread mapping);
376      - fix Min & Max for case where 1 thread has only empty tiles;
377      - use RL variable to count number of wet grid points (with big domain,
378        can be too large to fit into integer*4).
379    o pkg/monitor:
380      - use RL variable to count number of wet grid points (but used only for del2)
381      - add new routine to compute Advective CFL within tracer time-stepping with
382        writing delayed until next monitor output.
383    o pkg/obcs:
384      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
385    o pkg/cal:
386      - calandar-dump: treat case myTime < timePhase in the same way as in
387        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
388    o pkg/dic & seaice:
389      - fix compilation of ocean component for coupled atm+ocn model with
390        seaice dynamics & dic.
391    
392    checkpoint65x (2016/06/11)
393    o add a license text file in main MITgcm tree.
394    o added pkg/bling:
395      - intermediate complexity biogeochemical model
396      - see bling_description.txt for details
397      - verification experiment is global_oce_biogeo_bling (for now, in
398        Contrib/verification_other/); tested daily on baudelaire with gfortran.
399      - add entry point in pkg/gchem for new pkg "bling".
400    o pkg/seaice: fix tensile stength computation
401      - replace global field tensileStrength by tensileStrFac
402      - tensileStrFac can be computed once in S/R seaice_init_varia
403      - fortunately that does not affect any verification results
404    
405    checkpoint65w (2016/05/12)
406    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
407         with ECCO_CTRL_DEPRECATED defined
408    o verification/global_ocean.cs32x15:
409      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
410        with "selectNHfreeSurf=1".
411    o model/src (non-hydrostatic free-surface):
412      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
413        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
414      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
415        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
416        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
417        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
418      - Update output (changes at machine truncation level) of verification exp:
419        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
420        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
421    o pkg/seaice: ITD code
422      - fix picking up from a single category model by initialising
423        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
424      - split a long warning message in seaice_check_pickup.F into two lines,
425        because NEC SX-ACE cannot deal with the long line.
426    o model/src:
427      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
428    o pkg/seaice:
429      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
430    o pkg/seaice:
431      - add basal stress as parameterisation for grounding ice
432        following Lemieux et al. (2015)
433      - turn on by setting new parameter SEAICEbasalDragK2 to a value
434        larger than 0. Lemieux et al. (2015) recommend 15.
435      - The adjoint complains with extra recomputations so there is also a
436        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
437        order to postpone the problem
438      - compile the new code in lab_sea
439    o verification/halfpipe_streamice:
440      - update both TAF and OpenAD adm output (machine truncation differences)
441    
442    checkpoint65v (2016/04/08)
443    o verification/advect_xz:
444      - increase overlap size from 3 to 4 and add new secondary test for PQM
445        advection scheme (with mono & wino limiter).
446      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
447    o model/src:
448      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
449        added phi0Ref) to set vertical axis origin and phiRef origin;
450        keep Ro_SeaLevel for backward compatibility (with a warning).
451       According to coordinate and fluid type:
452        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
453        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
454        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
455        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
456      - remove Ro_SeaLevel from ATM experiment parameter files;
457      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
458        complement; update output.txt (changes at machine truncation level).
459    o pkg/seaice/seaice_evp.F
460      - simplify computation of deltaZ and zetaZ to simple averaging following
461        Bouillon et al. (2013). This removes a lot of code, but also changes
462        verification experiment lab_sea.hb87 -> updated
463    
464    checkpoint65u (2016/03/14)
465    o pkg/generic_advdiff:
466      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
467        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
468        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
469        testing and not for actual use.
470    o model/src:
471      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
472        origin r = rF(1);
473      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
474        in EOS for height coordinate: enable to include NH Pressure or to use
475        more accurate pressure vertical profile; options not linked to EOS type
476        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
477      - start to implement variable gravity (along vertical): for now, only with
478        z-coords (not even z*).
479      - add Ideal Gas equation of state for height coordinate.
480      - update OpenAD output (affected at machine truncation level) of exp:
481        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
482    o pkg/exf:
483      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
484        of exf interpolation (before any rescaling, rotation or interpolation
485        to velocity point) for each field that gets loaded from file. This option
486        identically mimics the input file organization (e.g. record numbers in year
487        by year input files) besides the change in horizontal grid.
488      - add rotateStressOnAgrid run-time switch so that wind stress fields
489        can be provided on the A-grid in zonal/meridional direction and
490        rotated on the fly. This only applies to the case when the exf
491        interpolation is off and rotateStressOnAgrid is false by default.
492    o model/src:
493      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
494        it's also used with pkg/atm_phys) and add few more parameters (but still
495        inactive, src code yet to come)
496    
497    checkpoint65t (2016/02/10)
498    o pkg/atm_phys:
499      - from Ruth Geen: add optical depth dependence on CO2 concentration.
500    o model/src:
501      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
502        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
503        Update output of exp. deep_anelastic (changes at truncation level).
504    o tools:
505      - add a hack in "remove_comments_sed" (used only with TAF) for recent
506        version of OpenMPI (shipped with FC.23): comment out the new header
507        file "mpif-sizeof.h" which causes problems to TAF.
508    o pkg/seaice:
509      - change the termination criterion so that maxits (SEAICElinearIterMax)
510        has an effect
511      - unify iteration parameters for implicit solvers (JFNK and Picard)
512        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
513        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
514        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
515        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
516        SEAICEnonLinTol     replaces JFNKgamma_nonlin
517      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
518      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
519        use with SEAICEuseKrylov
520    o pkg/seaice/seaice_lsr.F
521        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
522        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
523        an effect.
524    o pkg/seaice: add two new parameters
525      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
526        parameter is not in any namelist)
527      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
528        a preconditioner for the non-linear Newton iteration of the JFNK
529        solver
530    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
531      affects some experiments at truncation level:
532      - global_ocean.cs32x15.icedyn (11 digits),
533      - global_ocean.cs32x15.seaice (11 digits),
534      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
535      - also update global_ocean.cs32x15 adjoint and tangent-linear results
536    o pkg/salt_plume & pkg/thsice:
537      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
538        connect salt_plume flux to ATM-OCN coupling pkgs interface:
539       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
540         export to coupler interface) even without compiling pkg/salt_plume ;
541       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
542         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
543    o pkg/dic:
544      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
545        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
546        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
547      - move also update with values from ATM-OCN Coupler in the same new S/R
548        (previously done in ocn_apply_import.F).
549    o tools/adjoint_options:
550      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
551        has been changed on Jan 14, 2016.
552    o pkg/ggl90:
553      - add alternative discretisation of vertical shear (off by default), to
554        compute the mean (@ grid-cell center) of vertical shear compon instead of
555        vertical shear of mean flow (@ grid-cell center).
556      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
557        results on adjacent faces of cubed-sphere grids; this fix the restart.
558    o pkg/atm_compon_interf:
559      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
560        pass last value, stored directly before export to CPL ;
561        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
562      - remove atmSLPr from pickup files (no longer needed for restart)
563    
564    checkpoint65s (2016/01/13)
565    o eesupp & genmake2:
566       - first check for Function ETIME and, if it fails, then check for subroutine
567         ETIME and consistent output; use the appropriate version in timers.F
568    o model/src:
569      - to check restart test, add option to apply EXCH to U,V earlier, just before
570        integr_continuity; turned off by default.
571    o pkg/dic:
572      - remove CPP option USE_ATMOSCO2 (not needed)
573    o tools/tst_2+2:
574      - try to ignore difference between +0 and -0 in binary file, causing test
575        to fail for no good reason.
576    o eesupp & genmake2:
577      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
578        but also check (in genmake2) that test runs and returns meaningful results.
579    o coupler pkgs:
580      Finish implementation of optionally-exchanged variable switches (started on
581       Nov 12) with addition of few more exchanged fields, including 2-way exchange
582       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
583       advection in OCN component; this requires sequential coupling.
584      coupler (pkg/atm_ocn_coupler):
585      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
586        routines (useful for debug).
587      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
588         flux, DIC fields) if corresponding switch is ON.
589      - add option to export RunOff to OCN (to use for DIC river input)
590      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
591      components (pkg/atm_ & ocn_compon_interf):
592      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
593        optionally exchanged fields; add a check & stop in cpl_readparms.F.
594        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
595        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
596      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
597        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
598      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
599      - hold in common block coupler optionally-exchanged variable switch
600        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
601      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
602        this is intended to replace the OCN cplFldtave.* output files (not updated
603        to contain new additional exchanged fields).
604    o pkg/dic:
605      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
606    o pkg/thsice:
607      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
608        and writing of thsice pickup files.
609    o pkg/atm_compon_interf:
610      - move all field individual export-call out of cpl_export_import_data.F
611        into new S/R ATM_EXPORT_FIELDS
612    o pkg/atm_compon_interf:
613      - store state variables (for now, only thSIce fields) just before beeing
614        exported (in cpl_export_import_data.F, like on ocean side) instead of from
615        atm_store_my_data.F like all exported fluxes.
616      - new version of pickup_cpl: write field names into meta file and read meta
617        file to find field postion in pickup. Also only write/read fields meeded for
618        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
619    o pkg/dic:
620      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
621    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
622        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
623        value can be from domain [0,1] to average between the two methods
624    o pkg/atm_phys:
625      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
626        hold fixed in time).
627    
628    checkpoint65r (2015/12/21)
629    o pkg/seaice:
630        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
631        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
632    o pkg/seaice:
633      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
634        when SEAICEscaleSurfStress=.TRUE.,
635      - apply areaW and areaS in S/R seaice_calc_lhs
636    o pkg/atm_phys:
637      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
638        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
639        for individual contribution (convection, LSC cond, radiation)
640      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
641        information); activated with: solar_exponent=0. and wv_exponent=-1.
642    o pkg/ggl90:
643      - within IDEMIX add upper limit for horizontal group velocity to
644        avoid instability problems in the explicit horizontal diffusion term for
645        long time steps or high resolution
646    o pkg/diagnostics:
647      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
648        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
649    o testreport:
650      - remove "-v" (verbose option) in default mpirun command.
651    o pkg/seaice/seaice_growth:
652      - catch potential division by zero in ITD code, does not change
653        verification results
654    o pkg/ecco:
655      - retire old codes to the Attic. The calls to retired functions are
656        left in a commented form in case they ever need to be re-activated.
657      - ecco_check.F: issue warning if any old CPP option is
658        defined that corresponds to retired codes -- then stop.
659    o pkg/atm_compon_interf:
660      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
661        coupler: use last time-step value instead of average over cplSendFrq_iter
662        time-step, similar to what is done for seaIceMass.
663        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
664    o eesupp & genmake2:
665      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
666        <= remove until a fix is found for some ifort version on ia32 machine.
667    o pkg/seaice/seaice_evp:
668      - refine residual computation
669    
670    checkpoint65q (2015/11/18)
671    o pkg/seaice/seaice_evp:
672      - fix residual computations so that they no longer affect the actual
673        simulation code
674      - fix seaice_readparams to be able to actually set new parameters
675        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
676    o model/src:
677      - fix wrong truncation (single prec) from "FLOAT" function in expressions
678        like: deltaT*FLOAT(myIter) when myIter is large:
679         a) replaced by DFLOAT (if not seen by TAF);
680         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
681    o pkg/aim_v23:
682      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
683        when pickupSuff is set ; do write rolling pickups + at the end of the run.
684    o pkg/atm_ocn_coupler + ocn_compon_interf:
685      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
686        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
687        add corresponding call in DO_OCEANIC_PHYS.
688    o coupler pkgs:
689      Start a new way to set-up optionally-exchanged variables (previously, only
690       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
691       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
692       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
693       compononent param default can be set accordingly).
694      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
695       but rather applies to a group a fields (going both ways like for DIC)
696       and corresponds to an option of coupling config.
697      coupler (pkg/atm_ocn_coupler):
698      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
699        and read namelist directly (without eessup S/R calls) instead of
700        in the very un-flexible old way, 1 param per line, in fixed order;
701      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
702        cleanly in CPL_CHECK_CPLCONFIG
703      - add new coupling-exchange selectors (some not yet active) including
704        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
705                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
706      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
707        component ; called directly from coupler.F, after comp. registrations;
708      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
709         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
710          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
711      components (pkg/atm_ & ocn_compon_interf):
712      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
713        CPP header file in all pkg source files.
714      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
715        ATM/OCN_CHECK_CPLCONFIG;
716      - add error-counter to track errors (e.g., in "data.cpl") and to stop
717        cleanly in ATM/OCN_CHECK_CPLCONFIG;
718      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
719        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
720        before PACKAGES_READPARMS;
721      verification/cpl_aim+ocn/:
722      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
723        "data.cpl" for coupler (in input_cpl).
724    o eesupp/inc:
725      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
726        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
727        to always cumulate tile local-sum in the same order (still uses
728        MPI_Allreduce like standard code).
729      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
730        that are now identical to standard version (in eesupp/inc).
731    o pkg/shelfice:
732      - add SHELFICETransCoeffTFile for initializing spatially varying
733        heat and salt transfer coefficients
734    o pkg/atm_compon_interf & ocn_compon_interf:
735      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
736        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
737      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
738    o pkg/atm_ocn_coupler:
739      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
740    o pkg/rbcs:
741      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
742        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
743      - add a short report (to STDOUT) about RBCS-mask settings.
744    
745    checkpoint65p (2015/10/23)
746    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
747        there is no adjoint test for EVP, we don't know what it does to the adjoint
748        solution, but at least there are no more recomputation warnings left
749    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
750        a chance of giving the same results as a fully converged VP (JFNK) solver
751    o tools/adjoint_options/adjoint_diva:
752      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
753    o pkg/streamice:
754      - spotted bug in streamice_driving_stress using dyG where should have been dxG
755    o pkg/exf:
756      - remove STOP statement that prevented to use wind or (wind-)stress
757        interpolation for constant-in-time forcing fields (wind/stress period = 0).
758    o pkg/seaice:
759      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
760        5 additionals 2D fields and 6 new store directives
761      - change logic in seaice_readparms.F: EVP code can now be turned on in
762        various ways, setting SEAICE_deltaTev is no longer required,
763        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
764        or SEAICEaEVPcoeff
765    o pkg/shelfice/shelfice_thermodynamics.F
766      - redefining uLoc/vLoc to u/v, instead of 2u/v
767    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
768      - this is an intermediate state of a truely converging EVP that has
769        the potential of outperforming implicit VP methods, I do not recommend
770        using it yet.
771      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
772        and all parameters are hardwired
773      - for convergence it still requires very smooth regularisations, that means,
774        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
775        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
776        specific averaging appears to be required, still subject to tuning
777      - still needs cleaning and I need to turn parameter into runtime parameters
778      - add code to compute and print residuals of iteration, compile with
779        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
780    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
781      that entered with r1.54 on Sep04, 2015, -> update results
782    
783    checkpoint65o (2015/09/14)
784    o pkg/mom_vecinv & mom_common:
785      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
786        called from there.
787      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
788        allows to use Vector-Invariant form in deep atmos and anelastic formulation
789    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
790      and Koenig-Beatty+Holland (2012)
791      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
792      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
793      - requires an extra input argument for S/R seaice_calc_viscosities
794      - tensileStrength's depth dependence is different from Itkin et al. (2015)
795        (to be changed and played with, for now exponential)
796    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
797      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
798        by AREA according to Connelly et al. (2004), JPO.
799      - For EVP and the LSR solver, the implicit part of the drag term is
800        the only non-zero term in the denominator when there is no ice (which
801        prevented running the model with zero ice-ocean drag). If
802        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
803        (or zero main diagonals BU/BV) which need to be caught. A practical
804        consequence is that for open water, the momentum equation reduce
805        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
806        they happen to be zero, often leading to a non-zero solution over
807        open water.
808    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
809        efficient EVP method.
810      - introduce area-weighted averages for e12 (analogously to
811        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
812        remain, but also changing the order of terms in the previous average
813        changed the results as much) -> update experiment
814      - add SEAICE_DELTA_SMOOTHREG code
815      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
816        TEM-code
817      - adjust loop bounds so that only required fields are computed
818      - add new averaging code for zetaZ/deltaZ (again similar to
819        seaice_calc_viscosities.F), inactive by default for now (will change
820        results again), but will replace old code eventually
821    o eesupp/src:
822      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
823        to always cumulate tile local-sum in the same order
824        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
825        Still uses MPI_Allreduce (like standard code) but on array of tiles
826        and should be faster than GLOBAL_SUM_SEND_RECV code.
827      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
828        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
829      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
830         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
831         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
832         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
833         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
834    
835    checkpoint65n (2015/07/29)
836    o pkg/thsice:
837      - add a warning when used with pkg/aim but without updating SST
838        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
839    o pkg/offline:
840      - change where Offline-Fields are loaded, from load_fields_driver.F to
841        directly within FORWARD_STEP, just after updating iter number and time;
842      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
843        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
844       These changes allow:
845        a) to recover exactly on-line results using deltaToffline=deltaTClock,
846        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
847        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
848        time-step, both with GM & KPP files and with recomputing these fields;
849        b) no needs to switch on staggerTimeStep anymore;
850        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
851      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
852    o pkg/offline:
853      - change (rarely used) offset-iteration parameter to an offset time (in s):
854        can easily recover previous offset-iter effect by setting offset-time
855        (offlineTimeOffset) to offset-iter x deltaToffline;
856      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
857        in KPP as part of surface buoyancy forcing) in offline run.
858      - fix ptracers KPP non-local term in the case where KPP is re-computed.
859    o OpenAD
860      - Adding preliminary ggl90 test to OpenAD verification.
861        Config. with ggl90 currently diverges after 64 time steps
862        so will need more work to become more stable
863      - Adding preliminary kpp test to OpenAD verification.
864        required small tweakes in kpp_routines.F
865      - Merge and update from Krishna Narayanan's contrib area:
866        * Add one variable for preliminary OpenAD DIVA
867        * Add replacement time-stepping for OpenAD DIVA
868        * genmake2 flag -diva (but only for OpenAD; preliminary)
869        * required modifs for OAD_support
870        successful preliminary test for tutorial_global_oce_biogeo/
871    o pkg/seaice:
872      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
873      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
874        delta with a smooth function in s/r seaice_calc_viscosity
875        (no effect on EVP)
876      - rename local suffix "sqr" into "sq" for more consistent variable names
877    o pkg/seaice:
878        add new parameter SEAICE_deltaMin that is used ***only***
879        for regularizing Delta (and nothing else, like the parameter
880        which is also used for all sorts of things SEAICE_EPS).
881        Defaults to SEAICE_EPS for backward compatibility only.
882    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
883        the wrong key by inialising it before use -> fixes a recomputation
884        problem but does not fix the gradient
885    o pkg/layers:
886      - move resetting of flux arrays to outside the iLa loop
887        (this caused layers_diapycnal to not work with more than one layer coord.)
888      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
889    o pkg/layers:
890      - remove from common block 3D layers fields (used to diagnose transport
891        in tracer coords) and declare them as local arrays in layers_calc.F
892    o pkg/seaice:
893      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
894        in lab_sea forward experiment (changes results -> updated)
895      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
896    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
897       computations; for SEAICE_VECTORIZE_LSR
898      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
899        sweep to the outside,
900      - remove store directives and add "CADJ loop sequential" directives
901        in analogy to model/src/solve_tridiagonal.F
902      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
903        boundaries to yield more readable code. This has also the charming side
904        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
905        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
906        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
907        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
908        an additional option)
909       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
910       but the adjoint gradients (which are affected by this change) still explode.
911    o coupler (atm & ocn _compon_interf):
912      - avoid using Exch2 IO mapping if not suitable.
913    
914    checkpoint65m (2015/06/15)
915    o pkg/layers:
916      - clean-up old parameters setting (from Sep 2012):
917        + remove old parameters setting from common block (declared locally);
918        + stop if any old parameter is mixed with new parameters;
919        + check for valid or consistent parameter setting (e.g., layers_name)
920      - check that layers_bounds for Pot.Density are in the right range;
921        this is supposed to catch un-updated setting after recently shifting
922        potential density field "prho" by -1000 (now in "sigma" scale).
923    o pkg/layers:
924      - Added missing call to layers_fill for keeping track of tottend in
925        pkg/diagnostics/diagnostics_fill_state.F
926    o pkg/layers:
927      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
928        of diapycnal fluxes
929    o pkg/layers:
930      - reverted changes to interpolation to previous treatment; there
931        was never actually a problem
932    o pkg/layers:
933      - fix interpolation of layers tracers in the presence of partial cells
934      - add lots of new functionality to compute water mass transformation
935        (enabled by CPP flag LAYERS_THERMODYNAMICS)
936      - add new calls from main code (diags_oceanic_surf_flux.F,
937        thermodynamics.F, impldiff.F) and gad to save the necessary fields
938        for layers_thermodynamics calculations
939    o pkg/ptracers:
940      - add capability of stepping a passive tracer forward without advection
941        by setting PTRACERS_advScheme to 0.
942    o pkg/diagnostics:
943      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
944    o pkg/layers:
945      - shift potential density field "prho" by -1000 for density layer averaging so
946        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
947        Note that density bin boundaries (layers_bounds in data.layers) have
948        to be set accordingly (i.e., shifted, in sigma scale).
949    o pkg/layers:
950      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
951      - fix calculation of layer non-weighted velocity and layer probability
952      - add diagnostics for pot.density used for layer averaging
953    o pkg/seaice:
954      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
955        positiveness, modify a few comments and improve variable names,
956      - the changed computation of deltaC affects most seaice-related
957        experiments at the truncation level.
958        seaice_itd.thermo is affected by far the most, with
959        only 7 digits of agreement remaining; update experiments.
960    
961    checkpoint65l (2015/05/04)
962    o pkg/shelfice:
963      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
964        factor drKp1 to zero where it is negative (ie. do not use
965        SHELFICEBoundaryLayer if hFacC>1)
966      - the same for factor drLoc in shelfice_forcing.F
967    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
968        with modules in ptracers, when using testreport option "-small_f"
969    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
970      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
971    o verification/testreport
972      - add new option -small_f
973        with this option testreport first makes the target small_f (*.f files)
974        before running make (all). This is useful for explicit inlining when
975        all sources need to be full available.
976    o pkg/exf/exf_interp.F:
977        remove previous changes related to reverse (decreasing) input grids latitude
978    
979    checkpoint65k (2015/04/01)
980    o pkg/ecco:
981        fix missing cosphi initialization; use eccoiter in place of optimcycle;
982        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
983        instead of active read/write
984    o pkg/ctrl:
985        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
986        instead of active read/write.
987    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
988        return if .NOT.useAUTODIFF
989    o pkg/seaice: add CPP brackets (cost function related).
990    o model/src:
991        add useAUTODIFF run time switch.
992    o pkg/exf/exf_interp.F:
993        add code to allow input grids with latitude starting in the north (i.e. when
994        j=1 corresponds to northern edge of field); modify global_with_exf to test
995        this feature.
996    o verification/testreport:
997      - replace "grep -A3" with POSIX conformal sed command, because there are
998        implementations of grep that cannot do contextual searches
999      - replace "cat -n" by "nl" (two occurrences), because not all implementations
1000        of "cat" have the option "-n"
1001    o model/src:
1002        add new file gsw_teos10.F that contains 3 functions, more or less a copy
1003        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
1004        convert from conservative to potential temperature. For now they are not
1005        called anywhere.
1006    o pkg/ggl90: make "useIDEMIX" useful
1007      - re-organize code in s/r ggl90_calc a little to move computations that
1008        are different for idemix into separate loops (changes verification
1009        experiment idemix at truncation level, 12 digits remain -> updated)
1010      - requires 2 new 2D fields KappaM, verticalShear
1011      - make hFacI and recip_hFacI local 3D variables that are passed to
1012        s/r ggl90_idemix
1013      - fix and improve some comments
1014    
1015    checkpoint65j (2015/02/25)
1016    o pkg/openad
1017      - synchronize seawater.F with version in model/src: replace routine
1018        body of sw_temp by calling sw_ptmp and fix/add a few comments.
1019    o pkg/mnc:
1020      - change default value of pickup_read/write_mnc params to FALSE
1021        (since few features are missing in reading MNC pickup files).
1022    o model/src:
1023      - change default (background) vertical diffusivity for salt to be the
1024        temperature (background) vertical diffusivity.
1025      - change background vertical diffusivity in vertical mixing pkgs ggl90,
1026        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
1027        This makes ptracers default diffusivity (that uses salt diffKr) more
1028        consistent with vertical mixing schemes.
1029    o verification/testreport:
1030      - fix typo in "-pcls" option ;
1031      - put temp files in /tmp (instead of in local dir)
1032      - add option "-ncad" to use genmake2 new option "-nocat4ad"
1033      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
1034    o pkg/ggl90 (idemix code):
1035      - apply few fixes ; add some missing "_d 0" ; update output of exp.
1036        global_ocean.90x40x15.idemix
1037    o OpenAD
1038      - enable active file I/O and begin removal of work-around code
1039        for OpenAD for handling control variables (memory vs. active files)
1040      - new CPP options file OPENAD_OPTIONS.h
1041      - revert to genarr2d gradient check for hs94.1x64x5
1042      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
1043      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
1044    o tools/genmake2:
1045      - add option for an alternative Makefile (from Martin) where multiple
1046        source files are sent to TAF (instead of all in one file).
1047    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
1048      - code provided by Carsten Eden as an extension of ggl90
1049      - so far the code is turned on within ggl90 by setting a CPP-flag at
1050        compile time; a runtime flag implementation is not yet complete
1051      - tested in new verification experiment global_ocean.90x40x15.idemix
1052    o verification:
1053      - reduce length of the AD test run by half for experiments
1054        global_ocean.cs32x15 (std + thsice) and isomip
1055      - enable active file I/O for OpenAD, adjust verifications accordingly
1056      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
1057    o verification/testreport:
1058      - fix two non-POSIX sed statements so that there are no error messages
1059        on Mac OS X
1060      - replace hostname -s with hostname | sed 's/\..*$//'
1061    o model/src/seawater.F:
1062      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
1063        (following the matlab code), which would have avoided the bug caught
1064        by Matt (see below) in the first place
1065    o pkg/shelfice:
1066      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
1067        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
1068      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
1069        ice-shelf case (i.e., within surface level).
1070      - add config summary in shelfice_check.F
1071      - remove global variable recip_SHELFICElatentHeat and replace by a local
1072        variable recip_latentHeat
1073      - introduce diagnostics for friction velocity uStar (in case of
1074        SHELFICEuseGammaFrict)
1075      - change verification experiment isomip.htd:
1076        + start from pickup (as input_ad at nIter0=8640)
1077        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
1078        + test SHELFICEuseGammaFrict = .TRUE.
1079        + test SHELFICEadvDiffHeatFlux = .TRUE.
1080    o model/src:
1081      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
1082        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
1083        update output of experiments global_with_exf.yearly and isomip (all 6).
1084    o pkg/shelfice:
1085      - change setting of kTopC to also be zero where there is no ice-shelf.
1086      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1087        ice-shelf is.
1088      - first attempt to get RealFreshWaterFlux effects: for now, only without
1089        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1090    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1091      for thermodynamic calculations
1092      - because of divisions of the type 7/7 not exactly equal to 1, this change
1093        affects results of some verification experiments by up to 4 digits:
1094        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1095        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1096        adjoint: lab_sea, lab_sea.noseaicedyn
1097        -> updated
1098    
1099    checkpoint65i (2015/01/23)
1100    o model/src:
1101      - change units of frictionHeating field from W to W/m^2
1102      - fix bug in frictional heating from stratospheric drag in
1103        S/R ATM_PHYS_TENDENCY_APPLY_V
1104      - with synchronous time-stepping: move resetting to zero of frictionHeating
1105        field from load_fields_driver.F to thermodynamics.F ;
1106      - add diagnostics for frictional heating.
1107    o model/src & gmredi K3D:
1108      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1109      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1110      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1111        and name in pickup file).
1112      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1113    o model/src:
1114      - move (from ini_forcing.F) initialisation of all arrays in header file
1115        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1116        (since Nov 2012) with option selectAddFluid=1.
1117    o pkg/shelfice:
1118      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1119      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1120    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1121    o pkg/seaice: two new runtime parameters:
1122      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1123        long overdue
1124      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1125        parameterization of tensil stress for fast ice (does not do anything yet)
1126    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1127        for LSR: move checking overlaps out of JFNK-if-block
1128    o pkg/atm_phys:
1129      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1130        new S/R ATM_PHYS_DYN2PHYS.
1131      - fix level height for Linear Free-Surf case (to be consistent with
1132        fixed-in-time pressure levels).
1133    o pkg/mom_common (bottomdrag):
1134      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1135        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1136        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1137    o pkg/shelfice (u/v_drag):
1138      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1139      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1140        (now similar to shelfice_u_drag.F)
1141      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1142        from mom_vecinv.F (similar to mom_fluxform calls).
1143    o pkg/mom_common (bottomdrag):
1144      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1145      - add options for alternative discretisation of velocity norm in quadratic
1146        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1147        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1148        improves when averaging only the other component (e.g. vVel for U bottom
1149        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1150      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1151        friction (no-slip BC) thus getting the true distance from the bottom;
1152        off by default since this also reduces model stability (explicit bottom
1153        friction). Changes produce different machine truncation with linear-drag
1154        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1155        front_relax (bvp & mxl, 10 & 11 digits).
1156    o model/src & mom pkgs:
1157      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1158        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1159      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1160        just copy level Nr value to level Nr+1.
1161    o doc:
1162      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1163    o pkg/shelfice:
1164      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1165        SHELFICE.h: move array shelficemass to init_varia, initialise
1166        from array shelficemassinit, which is set in init_fixed and
1167        has option to be set from file; introduce array
1168        shelficeMassDynTend array, set thru file in init_fixed
1169      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1170        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1171        pkg/streamice
1172      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1173        SHELFICEMassStepping = .true.
1174      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1175    
1176    checkpoint65h (2014/12/17)
1177    o verification/global_ocean.90x40x15, global_ocean_ebm:
1178      - update to generic controls.
1179    o pkg/ctrl:
1180      - ctrl_map_ini_genarr.F: test for igen>0
1181      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1182      - move gentim2d part of ctrl_map_ini_genarr.F to
1183        new separate routine : ctrl_map_ini_gentim2d.F
1184      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1185        add time variable weights and cyclic controls (time mean,
1186        seasonal cycle, etc) capabilities to gentim2d
1187    o pkg/ecco:
1188      - move reading of error, conversion to weights from
1189        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1190    o global_oce_llc90, cs32:
1191      - activte sbo.
1192      - CTRL_SIZE.h : add maxCtrlProc.
1193      - activate the new genctrl capabilities.
1194      - update following reorganization of global_oce_input_fields.tar.gz  
1195    o pkg/ctrl/ctrl_ad_diff.list:
1196      - add missing ctrl_init_rec.f
1197    o tools/OAD_support/keepOriginal:
1198      - add ctrl_init_rec.F
1199    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1200      - avoid recomputations of xx_gentim2d_dummy.
1201    o momentum diagnostics:
1202      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1203        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1204    o pkg/seaice/seaice_lsr.F:
1205      - fix computation of BU/BV, make sure they are non-zero, only necessary
1206        for cubed sphere exchanges and SEAICE_OLx/y>0.
1207        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1208    o verification/global_ocean.cs32x15/input.seaice
1209      - add test for strong implicit coupling and restricted addtive Schwarz
1210        methods for LSR
1211      - update results/output.seaice.txt
1212    o verification/tutorial_global_oce_biogeo:
1213      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1214        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1215        update output_adm,_oadm,_tlm.txt
1216    o pkg/dic:
1217      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1218      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1219        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1220    o verification/tutorial_global_oce_biogeo:
1221      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1222        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1223        update output_adm,_oadm,_tlm.txt
1224    o eesupp/src:
1225      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1226        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1227    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1228      LSR (following Hutchings et al. 2004)
1229      - introduce zetaZ as a global variable (requires adjustments in
1230        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1231        in seaice_calc_viscosities.F
1232      - new flag SEAICEuseStrImpCpl (default off)
1233      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1234        momentum equations
1235      - JFNK-solver (preconditioner) adjusted to allow using this method
1236        (where it does not have any positive effect)
1237    o pkg/seaice
1238      - add overlap for restrictive additive Schwartz method also to LSR, but
1239        turn it off by default (because it only seems to work for non-cubed
1240        sphere/llc topologies)
1241    o pkg/autodiff
1242      - add extra exchanges in addummy_in_steppging also for mnc output
1243    o pkg/seaice:
1244      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1245        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1246    o pkg/obcs:
1247      - add option to specify domain-connected piece Id along OB though files
1248        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1249      - modify obcs_diag_balance.F to process each connected-part separately;
1250        exclude OB where Id = 0 but keep the full divergence there (-> constant
1251        Psi along this portion of OB and all inflow derived from grad(Phi))
1252      - add example of OB-conect files in verification/so_box_biogeo/input.
1253    o pkg/diagnostics:
1254      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1255      a) use non zero matrix element across OB and solve for Phi 1 grid point
1256         outside OB (i.e, where tracer OBCS are applied).
1257      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1258         velocity across OB, spread it uniformly along the OB in the RHS.
1259    
1260    checkpoint65g (2014/11/19)
1261    o pkg/diagnostcis:
1262      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1263    o pkg/my82,pp81,kl10:
1264      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1265        field diffKr as background diffusivity to set minimum diffusivity value.
1266    o pkg/seaice:
1267      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1268        Bouillon et al 2013)
1269      - add SEAICE_evpAlpha/Beta to namelist
1270      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1271        involve trivial re-ordering of divisions/multiplications that should not
1272        have any effects, but ... they do change the results of lab_sea.hb87 so
1273        that only 2 digits of agreement remain, in line with the general
1274        instability/fragility of the evp-code. For now, I do not care and just
1275        update the verification experiment
1276    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1277      - remove xx_genarr2d_numsmooth etc
1278      - use xx_genarr2d_preproc etc instead
1279      - carry out smooth_correl2D at initialization stage rather than during
1280        time stepping.
1281      - get smoothOpNb from xx_gentim2d_preproc
1282    o global_oce_cs32 :
1283      - add test of generic ecco capabilities.
1284    o pkg/exf/exf_getsurfacefluxes.F :
1285      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1286    o pkg/ctrl,ecco :
1287      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1288        is defined.
1289    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1290    o model/src:
1291      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1292        diffusivity (background) is specified but ignored.
1293    o verification:
1294      - in testreport, convert hostname to lower case for default output dir name
1295    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1296    o pkg/dic: add modifications from Hajoon:
1297      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1298      - light attenuation: add self-shading effect by climatological Chlorophyll
1299        (read from file).
1300    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1301        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1302    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1303        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1304        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1305        approach where CPP_OPTIONS.h includes an omnipotent
1306        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1307    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1308        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1309    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
1310        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
1311        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
1312    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
1313      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
1314      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
1315      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
1316      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
1317    o pkg/ctrl,ecco,exf :
1318      - remove variables associated with NON-generic costs,
1319        unless ECCO_CTRL_DEPRECATED is defined.
1320      - remove NON-generic NON-obcs controls,
1321        unless ECCO_CTRL_DEPRECATED is defined.
1322    o pkg/ctrl : added ctrl_local_params.h
1323    o pkg/ecco : added ecco_local_params.h
1324    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
1325        experiments, which will progressively be removed once the
1326        experiments are revised to use only generic controls/costs.
1327    
1328    checkpoint65f (2014/10/13)
1329    o pkg/ctrl, ecco, seaice : minor changes in headers
1330    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
1331        cost function and control capabilities added since checkpoint65c.
1332    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
1333    o pkg/ecco: increase modularity and improve logic
1334      - ecco_toolbox.F (new) : basic operations that are often used,
1335        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
1336        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1337      - cost_gencal.F (new) : determine filnames and records.
1338      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1339      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1340        and exploit the above functions leading to more compact code.
1341      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1342      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1343        using_ers, using_gfo, using_mdt is now only defined within gencost)
1344    o pkg/ecco: extend generic cost capabilities
1345      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1346        capabilities via gencost_preproc (+ _c,_i,_r related params),
1347        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1348        gencost_outputlevel arguments to cost_generic
1349      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1350        and active_read, making room for gencost_preproc to take effect.
1351        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1352      - pkg/ecco/cost_generic.F :

1361      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1362    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1363    o pkg/ecco: internal re-organization
1364      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1365        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1366        mv relevant variables definition from ecco_cost.h to ecco.h,
1367        make sure gencost routines only include ecco.h)
1368      - throughout : add missing CCP switches, rm unused variables,
1369        and rm un-necessary CPP switches
1370      - throughout gencost routines : replace modelstartdate with
1371        gencost_startdate when needed
1372      - cost_bp_read.F : use arguments, instead of common blocs
1373        so that it can be used also by (new) cost_gencost_bpv4.F

1375      - ecco_phys.F : compute etanFull
1376      - ecco_readparms.F : rename using_topex as using_tpj, add
1377        bpv4-grace to gencost list, initialize added parameters
1378      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1379    
1380    checkpoint65e (2014/09/28)

1386        (see pkg/obcs/OBCS_OPTIONS.h for details)
1387    o pkg/atm_phys:
1388      - implement simple (obliquity only, assuming circular planet orbit)
1389        seasonal cycle for incoming insolation ; used when run-time parameter

1400        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1401      - add weight in CTRL_GET_GEN calls
1402    o pkg/ctrl :
1403      - ctrl_get_gen.F : add weight as input parameter, and apply
1404        it directly rather than using smooth_correl2Dw (to be retired).

1421        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1422    o pkg/ctrl/ctrl_map_ini_genarr.F :
1423      - remove compilation failure
1424      - replace hard coded example
1425      - use ctrl_map_ini_gen2D, 3D
1426    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :

1443      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1444    o ecco/ecco_ad_diff.list :
1445      - add ecco_init_varia.f
1446    o ecco/ecco_init_varia.F
1447      - new routine
1448    o pkg/streamice:
1449      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1450        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1451      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1452    o pkg/generic_advdiff:
1453      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1454    o pkg/exf:
1455      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1456         xxg_precip capability
1457      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch

1461      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1462        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1463    o OpenAD verification experiments:
1464      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1465        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1466        for now, only in pkgs used in OpenAD verification experiments.
1467      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1468        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1469        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1470        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1471    o OpenAD verification tests:
1472      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1473      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1474        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1475      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1476        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1477    o model/src & generic_advdiff:
1478      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1479        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1480        dynamics requires valid tracer forcing only over tile interior but, for
1481        some diagnostics, may need to extend it over 1 point in tile halo region.
1482      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1483        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1484        setting in temp/salt/ptracer_integrate.F
1485  o pkg/dic:  o pkg/dic:
1486    - multiply tracer tendencies by maskInC (if ussing OBCS) before updating    - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
