4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model:
8      - add missing CPP brackets (ALLOW_COST, ALLOW_CTRL in load_fields_driver.F
9        and the_model_main.F)
10    o ctrl:
11      - use zeroRL in place of fc when ALLOW_COST is not compiled (in ctrl_pack.F)
12      - call MDS_READ_FIELD / MDS_WRITE_FIELD instead of deprecated
13        mdsreadfield / mdswritefield (in ctrl_get_gen.F, ctrl_map_ini_gen.F,
14        ctrl_map_ini_genarr.F, and ctrl_map_ini_gentim2d.F )
15    o eesupp:
16      - add CPP option to activate some pieces of code for coupling to GEOS AGCM;
17      - shift commonly used IO unit (in eeboot.F) for coupling to GEOS AGCM.
18    o pkg/bling:
19      - bling_production: Fix typo in calcium carbonate uptake. Also rearranging
20        and cleaning
21    o model/src:
22      - move k loop inside correction_step.F (+ update calling S/R)
23      - collect implicit pressure gradient tendencies in local 2-D array;
24        affect results (at machine truncation level) when using 3-D solver; update
25        output of exp.: exp4 (x1), global_ocean.cs32x15 (x2),hs94.cs-32x32x5.impIGW,
26                        rotating_tank, short_surf_wave,tutorial_deep_convection (x2)
27                        & tutorial_plume_on_slope.
28    
29    checkpoint66j (2017/08/15)
30    o pkg/ptracers:
31      - fix surface forcing under ice-shelf (useShelfIce=T).
32    o pkg/atm_phys:
33      - use hFac weighted average when applying A-grid atm-phys momentum tendency
34        to C-grid dynamics; this ensures wind-stress match mom tendency.
35    o eesupp/src:
36      - change default for opening scratch files to avoid STATUS='SCRATCH'
37      - close scratch files with STATUS='DELETE'
38      - changes affect eeset_parms.F and open_copy_data_file.F and many routines
39        that read namelists (because they close the scratch files)
40      - you can revert to old default by setting USE_FORTRAN_SCRATCH_FILES
41        in CPP_EEOPTIONS.h (tested in ideal_2D_oce/code & lab_sea/code_ad)
42    o pkg/atm_phys:
43      - fix unset arguments in (unused) S/R surface_flux_0d.
44    o eesupp/src:
45      - add argument "procId" to S/R EESET_PARMS to fix  scratchFile1 & 2 setting
46        (case TARGET_BGL or TARGET_CRAYXT) for early call (from eeboot_minimal.F):
47        called with myProcId in eeboot.F and with mpiMyWId in eeboot_minimal.F
48    o pkg/streamice:
49      - remove blank between _EXCH_XY_RL and "()", which my Apple Xcode
50        preprocessor /usr/bin/cpp cannot interpret; 3 instances in total in
51        streamice_driving_stress_fd.F and streamice_advect_2dtracer.F
52    o pkg/diagnostics:
53      - new option to allow to cumulate thickness-factor (hFac) weighted field
54        (if field permitted); implemented by changing sign of "jdiag" pointer
55        (> 0: cumlulate field, < 0: cumulate hFac weighted field).
56        a) restricted to 3-d (Nr levels), level centered diagnostics at U,V or Cell
57           center position (gcode(2)='U','V','M' & gcode(3,5,9:10)='R',' ','MR')
58        b) for now, activated by setting fileFlags 3rd character to 'h'.
59    
60    checkpoint66i (2017/07/18)
61    o pkg/cheapaml:
62      - add parameter "useRelativeWind", default set to False; this change the
63        previous setting which was always using relative wind.
64    o add hooks for the Parallel Data Assimilation Framework PDAF
65        (http://pdaf.awi.de/) in eeboot_minimal.F and the_main_loop.F;
66        to use set CPP-flag USE_PDAF in CPP_EEOPTIONS.h
67    o pkg/exf:
68      - interpolation of vector fields (exf_interp_uv.F): fix bug in calculation
69        of South-Pole mean value.  
70      - interpolation near the poles, case where second additional row is at the
71        pole (or beyond the pole and moved to the pole): change first addition row
72        value to a linear interpolation between pole and 1rst (S.pole)/last (N.pole)
73        row (instead of just a copy of it).
74    o pkg/seaice:
75      - prevent JFNK and KRYLOV solvers from trying to reduce a residual of 0
76      - add the option to compute no-slip du/dy, dv/dx (i.e.
77        the offdiagonal strain rate e12) by a second order approximation
78        on the boundary; works only with JFNK, KRYLOV, or EVP solvers, because
79        it is too messy to implement for the implicit LSR matrix.
80        SEAICE_2ndOrderBC = .FALSE. by default
81    
82    checkpoint66h (2017/06/02)
83    o pkg/seaice:
84      - add new routines to compute stress tensor components and stress tensor
85        divergence to be reused in s/r seaice_lsr and s/r seaice_calc_lhs
86      - change names of diagnostics SIsigI/II (commonly used for invariants)
87        to SIsig1/sig2 (more common for principal components) to avoid confusion
88    o pkf/exf:
89      - add a stop if useRelativeWind with un-updated uwind/vwind (e.g., constant);
90        similarly, stop if rotateStressOnAgrid with constant wind-stress.
91    o pkg/seaice:
92      - remove (comment out) diagnostics SIuwind,SIvwind,SIfu,SIfv (duplicate of
93        EXFuwind,EXFvwind,oceTAUX,oceTAUY) and point them to their equivalent.
94      - add diagnostics of wind-stress over seaice (SItaux,SItauy) and seaice
95        fraction weighted wind stress over ocean+seaice (SIatmTx,SIatmTy).
96    o pkg/diagnostics:
97      - small piece of code to rename (old) diagnostics, when namelist is processed.
98    o model/src:
99      - new run-time param (useMin4hFacEdges) to select method for setting hFacW,S:
100        originally, set as minimum of adjacent hFacC factor ; now (new default)
101        computed from rSurfW,S and rLowW,S by applying same rules as for hFacC.
102        Only matters when useShelfIce=T with particular ice-shelf cavity geometry.
103    o pkg/seaice:
104      - add momemtum advection, off by default, still in test phase
105        most of the momentum advection code is adapted and reused from mom_vecinv
106    o pkg/mom_vecinv:
107      - pass these runtime flags:
108        selectVortScheme, highOrderVorticity, upwindVorticity, useJamartMomAdv
109        as formal parameters to s/r mom_vi_u/v_coriolis, mom_vi_u/v_coriolis_c4,
110        so that these routines can also be used in pkg/seaice.
111    
112    checkpoint66g (2017/04/24)
113    o model/src:
114      - more robust ordering of column thickness integral (=Sum_k(drF*hFac) )
115        to get same expression (regarding machine truncation) in different places
116        in ini_masks_etc.F (e.g., rSurfC,W,S is now exactly zero when it should).
117        Update forward output of experiments: global_ocean.cs32x15 (all 5 except
118        viscA4), isomip (x3), tutorial_global_oce_in_p & tutorial_plume_on_slope.
119    o pkg/shelfice:
120      - ALLOW_SHIFWFLX_CONTROL: move setting of maskSHI from shelfice_update_masks.F
121        to shelfice_init_fixed.F
122      - change S/R SHELFICE_UPDATE_MASKS to SHELFICE_INIT_DEPTHS (still called from
123        ini_masks_etc.F for now) to update ocean upper boundary position according
124        to ice-shelf topography (instead of directly updating hFacC).
125    o model/src:
126      - move call to CTRL_INIT & CTRL_ADMTLM from the middle to the bottom of
127        packages_init_fixed.F to allow other pkgs to set mask and weight fields.
128    
129    checkpoint66f (2017/04/06)
130    o model/src:
131      - add specific run-time param to select level of printed plot-field-maps,
132        set by default to debugLevel. Remove internal param "printDomain".
133    o pkg/seaice:
134      - add flag to add snow mass to seaiceMassC/U/V, the default is
135        SEAICEaddSnowMass=.FALSE., not to change previous results
136    o pkg/bling
137      - Bug fix in bling_production regarding unit conversion for diagnostics
138        being put in the wrong place
139    o model/src:
140      - add back recomputation of rSurfW & S to ensure consistent column thickness
141        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
142        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
143        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
144    o pkg/autodiff:
145      - clean-up "checkpoint.flow"
146    o pkg/rw (Contribution from Jody Klymak):
147        option to set mds file suffix as function of time in simulation:
148        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
149           to select file suffix format; by default (=0), use iteration number;
150        *) add simple routine to return file suffix according to rwSuffixType;
151        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
152           use new S/R to get file suffix, except for debug output file (diagFreq)
153           and pkgs offline & rbcs input files.
154    o pkg/rw:
155      - uniform processing of "I10" suffix across writing fld routines; used to
156        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
157        (similar to cg3d.F, cg3d_ex0.F)
158    o pkg/mom_vecinv:
159      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
160        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
161    o pkg/bling:
162      - Many small changes intended to clean the code.
163        Unnecessary ADJOINT_SAFEs removed ;
164        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
165        diagnostics added.
166    
167    checkpoint66e (2017/03/14)
168    o pkg/exf:
169      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
170        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
171        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
172        avoid any dynamic allocation ;
173      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
174        read-in ; add warning when file is read-in but not used within pkg/exf ;
175        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
176      - update exf_summary.F (print {FLD}RepCycle).
177    o verification/global_with_exf:
178      - switch on exf interpolation in AD test (just like the forward test)
179    o pkg/mom_vecinv:
180      - add storage directives to avoid recomputations within mom_vecinv.F
181        which were generating seg. fault with gfortran -devel
182    o pkg/ctrl, pkg/smooth:
183      - initialize array halos which were generating seg. fault with
184        gfortran -devel in adjoint mode
185    o pkg/exf:
186      - for each input field, enable to specify a field specific repeat-cycle
187        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
188    o verification/lab_sea:
189      - update AD results of primary test and noseaicedyn test after switching
190        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
191        check stays about the same.
192    o pkg/exf:
193      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
194      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
195    o pkg/bling, USE_EXFCO2 code:
196      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
197      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
198    o pkg/exf:
199      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
200      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
201        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
202        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
203      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
204        EXF_INIT_FLD) and update calls in exf_init_varia.F
205      - For now, for backward compatibility, keep a simplified version of S/Rs
206        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
207      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
208        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
209    o tools/genmake2:
210      - replace "bc -l" (only used once) by "expr" (already used).
211    o verification/global_ocean.cs32x15:
212      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
213        Note: exf setting (data.exf) can be compared to other exf secondary exp
214        "seaice" (kept with useCAL=T) which has same time dependent forcing.
215    
216    checkpoint66d (2017/02/13)
217    o pkg/exf:
218      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
219        early on (in packages_boot.F) to stress this change in pkg setting.
220      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
221    o model/src:
222      - move call to ecco_phys to end of time step; this may induce minor
223        cost function changes by shifting time averages by one time step
224        for some variables; this revision resulted in changed adjoint results
225        in MITgcm_contrib/verification_other/global_oce_cs32
226    o pkg/exf:
227      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
228        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
229        e.g. precip, are not available.
230    o pkg/flt:
231      - flt_init_varia.F: use pickupSuff if specified
232      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
233        intermediate, step towards completing pkg/exch2 support within pkg/flt;
234        ifdef DEVEL_FLT_EXCH2 then:
235        - flt_init_fixed.F: comment out stop
236        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
237        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
238        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
239        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
240    o tools/genmake2 & pkg/pkg_depend:
241      - define new type of pkg dependency rule ("=pkg_x"), less strict than
242        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
243        (-pkg_x in packages.conf).
244      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
245      - add "+cal" to dependency list of pkg/ecco (needed to compile).
246      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
247    o utils/matlab:
248      - adding ocean_basin routines for defining basin masks.
249    o pkg/exf:
250      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
251        arguments, allowing to check (and stop) if parameter setting of
252         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
253        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
254        for backward compatibility.
255      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
256        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
257    o pkg/bling (USE_EXFCO2 code):
258      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
259        by adding a call to S/R EXF_GETFFIELD_START.
260    o pkg/exf:
261      - allows to compile without pkg/cal (but disabled by current dependency
262        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
263        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
264        of {FLD}startdate1 & date2 ; consistency check not yet coded.
265    o verification/global_ocean.cs32x15:
266      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
267        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
268    o pkg/exf:
269      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
270        calculations); change FWD experiment global_ocean.cs32x15
271        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
272    o pkg/exf:
273      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
274         {FIELD}startdate to {FIELD}StartTime
275        Note: new name also fit better the content, i.e, a start time in second.
276    o eesupp/src:
277      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
278    o pkg/exf:
279      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
280        to allow to read-in Sensible & Latent Heat flux ;
281      - simplify pkg/exf main options:
282        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
283           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
284           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
285        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
286           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
287        3) improve options documentation in EXF_OPTIONS.h.
288    o pkg/ecco:
289      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
290        ecco_summary.F: add passive tracer cost functions to gencost;
291        m_ptracer and m_boxmean_ptracer
292    o pkg/ctrl:
293      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
294        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
295        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
296        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
297    o model/src:
298      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
299        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
300    o pkg/exf:
301      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
302        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
303    
304    checkpoint66c (2017/01/19)
305    o verification:
306      - add new option "-src" to testreport to only produce source code (*.f),
307        including taf output src code (if using '-adm'/'-tlm' option).
308    o pkg/exf:
309      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
310    o pkg/diagnostics:
311      - add run-time variable diagMdsDir to specify a subdirectory for
312        diagnostic output when mds is being used and mdsioLocalDir is not.
313    o pkg/mnc:
314      - mnc_utils.F: edit stop message
315    o pkg/autodiff:
316      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
317        add HAVE_SYSTEM bracket around system call to mkdir
318    o pkg/profiles:
319      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
320        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
321      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
322        add HAVE_SYSTEM bracket around system call to mkdir
323    o pkg/smooth:
324      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
325      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
326      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
327    o pkg/exf:
328      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
329        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
330        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
331      - summary: skip detailed field report if not used (empty file-name).
332    o tools/xmakedepend:
333      - In case line editor "ed" is missing, switch to "sed" command to clean-up
334        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
335    o pkg/exf:
336      - change definition of "hflux" input file to always include Short-Wave;
337        this is now consistent with hflux computation (if using bulk-formulae)
338        and hflux diagnostic & documentation (in EXF_FIELDS.h).
339    
340    checkpoint66b (2016/12/01)
341    o model & momentum pkgs:
342      - implement fully implicit bottom friction combined with implicit surf.
343        pressure, for now, only in hydrostic formulation:
344        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
345          and run with selectImplicitDrag=2 ;
346        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
347      - partial implicit time-stepping (bot. friction + vert. visc first, then
348        surf. press) corresponding to selectImplicitDrag=1 should be applicable
349        to NH formulation but not available until we solve for surf. pressure
350        increment (instead of full etaN).
351      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
352        with implicit vertical viscosity.
353    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
354      - this is a first version that includes many regularisations that may
355        not all be necessary, to be sorted out,
356      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
357      - change one verification experiment in seaice_itd to use and test new code
358      - seaice_growth: catch a case where the argument of log can be zero
359        or smaller (important for code stability)
360    o model/src:
361      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
362        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
363        similar A.X'=Y' system (with same matrix A) in subsequent calls;
364        switch based on errCode (In/Out) argument value; in calling routines,
365        initialise errCode before first call.
366    
367    checkpoint66a (2016/10/18)
368    o pkg/bling:
369      - BLING package now loads in atmospheric pCO2 file using exf package routines
370        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
371    o model/src & pkg/ptracers:
372      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
373        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
374        implicitDiffusion (respectively) are used (even without momImplVertAdv
375        or temp,salt,PTRACERS_ImplVertAdv).
376    o model/src & generic_advdiff:
377      - add parenthesis in main diagonal calculation of implicit vertical
378        diffusion matrix (impldiff.F & gad_implicit_r.F).
379        This affects results at machine truncation level; update output of many
380        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
381    o pkg/mom_commom & generic_advdiff:
382      - add deep atmosphere and anelastic scaling factor in implicit vertical
383        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
384    o model/src:
385      - remove few unnecessary temp array copies in solve_tridiagonal.F
386        & solve_pentadiagonal.F
387    
388    checkpoint65z (2016/09/28)
389    o pkg/seaice: fix multithreading for seaice_fgmres.F
390      - remove unecessary variables from common blocks
391      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
392        basis, that are stored in commom blocks (including integer variable i1)
393      - clean up code a little by removing commented lines that refer to
394        original code
395      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
396    o MITgcm manual:
397      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
398        preliminary documentation for generic controls (8.3; ctrl.tex),
399        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
400        ecco_costfunction.tex
401    o pkg/ecco:
402      - update and cleanup list of CCP options
403      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
404        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
405      - add checks that retired run-time options are not used, and in relation
406        to gencost_mask and gencost_errfile
407      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
408        gencost_nrecperiod
409      - fix m_eta computation for virtual salt flux case
410      - add m_horflux_vol case (selected via gencost_barfile) that computes
411        transports via cost_gencost_boxmean (gencost_flag=-3)
412      - use gencost_flag more systematically (i.e., avoid using gencost_name)
413        for code switches (aside from physical variable selection)
414    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
415      attempt appears to be a bit of a hack and my need some repair down the road
416    o pkg/exf:
417      - interpolation near South Pole: fix criteria on input field latitude.
418    o pkg/icefront & pkg/exf:
419      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
420        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
421    o pkg/exf:
422      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
423        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
424        (add suffix "_out" instead of a prefix); keep same record number as in
425        input file but always write record 1 first (to avoid a STOP in I/O S/R).
426        Change output file content by writing interpolated field before applying
427        land-sea mask (helpful for debug).
428      - 2 compon. vector interpolation with rotation: apply scaling factor on
429        each compon. (Eastward and Northward) just before rotation.
430    o pkg/bling:
431      - Cleaned package. Removed not needed code and comments.
432      - adjoint example now works
433        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
434    o pkg/ptracers:
435      - add Bruno Deremble's code to complete the linear surface correction
436        for tracer conservation;
437      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
438    
439    checkpoint65y (2016/07/29)
440    o pkg/debug (stats):
441      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
442        proc/thread mapping);
443      - fix Min & Max for case where 1 thread has only empty tiles;
444      - use RL variable to count number of wet grid points (with big domain,
445        can be too large to fit into integer*4).
446    o pkg/monitor:
447      - use RL variable to count number of wet grid points (but used only for del2)
448      - add new routine to compute Advective CFL within tracer time-stepping with
449        writing delayed until next monitor output.
450    o pkg/obcs:
451      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
452    o pkg/cal:
453      - calandar-dump: treat case myTime < timePhase in the same way as in
454        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
455    o pkg/dic & seaice:
456      - fix compilation of ocean component for coupled atm+ocn model with
457        seaice dynamics & dic.
458    
459    checkpoint65x (2016/06/11)
460    o add a license text file in main MITgcm tree.
461    o added pkg/bling:
462      - intermediate complexity biogeochemical model
463      - see bling_description.txt for details
464      - verification experiment is global_oce_biogeo_bling (for now, in
465        Contrib/verification_other/); tested daily on baudelaire with gfortran.
466      - add entry point in pkg/gchem for new pkg "bling".
467    o pkg/seaice: fix tensile stength computation
468      - replace global field tensileStrength by tensileStrFac
469      - tensileStrFac can be computed once in S/R seaice_init_varia
470      - fortunately that does not affect any verification results
471    
472    checkpoint65w (2016/05/12)
473    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
474         with ECCO_CTRL_DEPRECATED defined
475    o verification/global_ocean.cs32x15:
476      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
477        with "selectNHfreeSurf=1".
478    o model/src (non-hydrostatic free-surface):
479      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
480        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
481      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
482        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
483        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
484        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
485      - Update output (changes at machine truncation level) of verification exp:
486        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
487        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
488    o pkg/seaice: ITD code
489      - fix picking up from a single category model by initialising
490        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
491      - split a long warning message in seaice_check_pickup.F into two lines,
492        because NEC SX-ACE cannot deal with the long line.
493    o model/src:
494      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
495    o pkg/seaice:
496      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
497    o pkg/seaice:
498      - add basal stress as parameterisation for grounding ice
499        following Lemieux et al. (2015)
500      - turn on by setting new parameter SEAICEbasalDragK2 to a value
501        larger than 0. Lemieux et al. (2015) recommend 15.
502      - The adjoint complains with extra recomputations so there is also a
503        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
504        order to postpone the problem
505      - compile the new code in lab_sea
506    o verification/halfpipe_streamice:
507      - update both TAF and OpenAD adm output (machine truncation differences)
508    
509    checkpoint65v (2016/04/08)
510    o verification/advect_xz:
511      - increase overlap size from 3 to 4 and add new secondary test for PQM
512        advection scheme (with mono & wino limiter).
513      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
514    o model/src:
515      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
516        added phi0Ref) to set vertical axis origin and phiRef origin;
517        keep Ro_SeaLevel for backward compatibility (with a warning).
518       According to coordinate and fluid type:
519        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
520        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
521        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
522        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
523      - remove Ro_SeaLevel from ATM experiment parameter files;
524      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
525        complement; update output.txt (changes at machine truncation level).
526    o pkg/seaice/seaice_evp.F
527      - simplify computation of deltaZ and zetaZ to simple averaging following
528        Bouillon et al. (2013). This removes a lot of code, but also changes
529        verification experiment lab_sea.hb87 -> updated
530    
531    checkpoint65u (2016/03/14)
532    o pkg/generic_advdiff:
533      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
534        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
535        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
536        testing and not for actual use.
537    o model/src:
538      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
539        origin r = rF(1);
540      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
541        in EOS for height coordinate: enable to include NH Pressure or to use
542        more accurate pressure vertical profile; options not linked to EOS type
543        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
544      - start to implement variable gravity (along vertical): for now, only with
545        z-coords (not even z*).
546      - add Ideal Gas equation of state for height coordinate.
547      - update OpenAD output (affected at machine truncation level) of exp:
548        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
549    o pkg/exf:
550      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
551        of exf interpolation (before any rescaling, rotation or interpolation
552        to velocity point) for each field that gets loaded from file. This option
553        identically mimics the input file organization (e.g. record numbers in year
554        by year input files) besides the change in horizontal grid.
555      - add rotateStressOnAgrid run-time switch so that wind stress fields
556        can be provided on the A-grid in zonal/meridional direction and
557        rotated on the fly. This only applies to the case when the exf
558        interpolation is off and rotateStressOnAgrid is false by default.
559    o model/src:
560      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
561        it's also used with pkg/atm_phys) and add few more parameters (but still
562        inactive, src code yet to come)
563    
564    checkpoint65t (2016/02/10)
565    o pkg/atm_phys:
566      - from Ruth Geen: add optical depth dependence on CO2 concentration.
567    o model/src:
568      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
569        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
570        Update output of exp. deep_anelastic (changes at truncation level).
571    o tools:
572      - add a hack in "remove_comments_sed" (used only with TAF) for recent
573        version of OpenMPI (shipped with FC.23): comment out the new header
574        file "mpif-sizeof.h" which causes problems to TAF.
575    o pkg/seaice:
576      - change the termination criterion so that maxits (SEAICElinearIterMax)
577        has an effect
578      - unify iteration parameters for implicit solvers (JFNK and Picard)
579        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
580        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
581        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
582        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
583        SEAICEnonLinTol     replaces JFNKgamma_nonlin
584      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
585      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
586        use with SEAICEuseKrylov
587    o pkg/seaice/seaice_lsr.F
588        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
589        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
590        an effect.
591    o pkg/seaice: add two new parameters
592      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
593        parameter is not in any namelist)
594      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
595        a preconditioner for the non-linear Newton iteration of the JFNK
596        solver
597    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
598      affects some experiments at truncation level:
599      - global_ocean.cs32x15.icedyn (11 digits),
600      - global_ocean.cs32x15.seaice (11 digits),
601      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
602      - also update global_ocean.cs32x15 adjoint and tangent-linear results
603    o pkg/salt_plume & pkg/thsice:
604      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
605        connect salt_plume flux to ATM-OCN coupling pkgs interface:
606       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
607         export to coupler interface) even without compiling pkg/salt_plume ;
608       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
609         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
610    o pkg/dic:
611      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
612        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
613        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
614      - move also update with values from ATM-OCN Coupler in the same new S/R
615        (previously done in ocn_apply_import.F).
616    o tools/adjoint_options:
617      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
618        has been changed on Jan 14, 2016.
619    o pkg/ggl90:
620      - add alternative discretisation of vertical shear (off by default), to
621        compute the mean (@ grid-cell center) of vertical shear compon instead of
622        vertical shear of mean flow (@ grid-cell center).
623      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
624        results on adjacent faces of cubed-sphere grids; this fix the restart.
625    o pkg/atm_compon_interf:
626      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
627        pass last value, stored directly before export to CPL ;
628        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
629      - remove atmSLPr from pickup files (no longer needed for restart)
630    
631    checkpoint65s (2016/01/13)
632    o eesupp & genmake2:
633       - first check for Function ETIME and, if it fails, then check for subroutine
634         ETIME and consistent output; use the appropriate version in timers.F
635    o model/src:
636      - to check restart test, add option to apply EXCH to U,V earlier, just before
637        integr_continuity; turned off by default.
638    o pkg/dic:
639      - remove CPP option USE_ATMOSCO2 (not needed)
640    o tools/tst_2+2:
641      - try to ignore difference between +0 and -0 in binary file, causing test
642        to fail for no good reason.
643    o eesupp & genmake2:
644      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
645        but also check (in genmake2) that test runs and returns meaningful results.
646    o coupler pkgs:
647      Finish implementation of optionally-exchanged variable switches (started on
648       Nov 12) with addition of few more exchanged fields, including 2-way exchange
649       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
650       advection in OCN component; this requires sequential coupling.
651      coupler (pkg/atm_ocn_coupler):
652      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
653        routines (useful for debug).
654      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
655         flux, DIC fields) if corresponding switch is ON.
656      - add option to export RunOff to OCN (to use for DIC river input)
657      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
658      components (pkg/atm_ & ocn_compon_interf):
659      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
660        optionally exchanged fields; add a check & stop in cpl_readparms.F.
661        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
662        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
663      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
664        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
665      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
666      - hold in common block coupler optionally-exchanged variable switch
667        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
668      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
669        this is intended to replace the OCN cplFldtave.* output files (not updated
670        to contain new additional exchanged fields).
671    o pkg/dic:
672      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
673    o pkg/thsice:
674      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
675        and writing of thsice pickup files.
676    o pkg/atm_compon_interf:
677      - move all field individual export-call out of cpl_export_import_data.F
678        into new S/R ATM_EXPORT_FIELDS
679    o pkg/atm_compon_interf:
680      - store state variables (for now, only thSIce fields) just before beeing
681        exported (in cpl_export_import_data.F, like on ocean side) instead of from
682        atm_store_my_data.F like all exported fluxes.
683      - new version of pickup_cpl: write field names into meta file and read meta
684        file to find field postion in pickup. Also only write/read fields meeded for
685        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
686    o pkg/dic:
687      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
688    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
689        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
690        value can be from domain [0,1] to average between the two methods
691    o pkg/atm_phys:
692      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
693        hold fixed in time).
694    
695    checkpoint65r (2015/12/21)
696    o pkg/seaice:
697        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
698        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
699    o pkg/seaice:
700      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
701        when SEAICEscaleSurfStress=.TRUE.,
702      - apply areaW and areaS in S/R seaice_calc_lhs
703    o pkg/atm_phys:
704      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
705        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
706        for individual contribution (convection, LSC cond, radiation)
707      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
708        information); activated with: solar_exponent=0. and wv_exponent=-1.
709    o pkg/ggl90:
710      - within IDEMIX add upper limit for horizontal group velocity to
711        avoid instability problems in the explicit horizontal diffusion term for
712        long time steps or high resolution
713    o pkg/diagnostics:
714      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
715        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
716    o testreport:
717      - remove "-v" (verbose option) in default mpirun command.
718    o pkg/seaice/seaice_growth:
719      - catch potential division by zero in ITD code, does not change
720        verification results
721    o pkg/ecco:
722      - retire old codes to the Attic. The calls to retired functions are
723        left in a commented form in case they ever need to be re-activated.
724      - ecco_check.F: issue warning if any old CPP option is
725        defined that corresponds to retired codes -- then stop.
726    o pkg/atm_compon_interf:
727      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
728        coupler: use last time-step value instead of average over cplSendFrq_iter
729        time-step, similar to what is done for seaIceMass.
730        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
731    o eesupp & genmake2:
732      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
733        <= remove until a fix is found for some ifort version on ia32 machine.
734    o pkg/seaice/seaice_evp:
735      - refine residual computation
736    
737    checkpoint65q (2015/11/18)
738    o pkg/seaice/seaice_evp:
739      - fix residual computations so that they no longer affect the actual
740        simulation code
741      - fix seaice_readparams to be able to actually set new parameters
742        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
743    o model/src:
744      - fix wrong truncation (single prec) from "FLOAT" function in expressions
745        like: deltaT*FLOAT(myIter) when myIter is large:
746         a) replaced by DFLOAT (if not seen by TAF);
747         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
748    o pkg/aim_v23:
749      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
750        when pickupSuff is set ; do write rolling pickups + at the end of the run.
751    o pkg/atm_ocn_coupler + ocn_compon_interf:
752      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
753        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
754        add corresponding call in DO_OCEANIC_PHYS.
755    o coupler pkgs:
756      Start a new way to set-up optionally-exchanged variables (previously, only
757       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
758       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
759       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
760       compononent param default can be set accordingly).
761      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
762       but rather applies to a group a fields (going both ways like for DIC)
763       and corresponds to an option of coupling config.
764      coupler (pkg/atm_ocn_coupler):
765      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
766        and read namelist directly (without eessup S/R calls) instead of
767        in the very un-flexible old way, 1 param per line, in fixed order;
768      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
769        cleanly in CPL_CHECK_CPLCONFIG
770      - add new coupling-exchange selectors (some not yet active) including
771        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
772                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
773      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
774        component ; called directly from coupler.F, after comp. registrations;
775      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
776         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
777          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
778      components (pkg/atm_ & ocn_compon_interf):
779      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
780        CPP header file in all pkg source files.
781      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
782        ATM/OCN_CHECK_CPLCONFIG;
783      - add error-counter to track errors (e.g., in "data.cpl") and to stop
784        cleanly in ATM/OCN_CHECK_CPLCONFIG;
785      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
786        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
787        before PACKAGES_READPARMS;
788      verification/cpl_aim+ocn/:
789      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
790        "data.cpl" for coupler (in input_cpl).
791    o eesupp/inc:
792      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
793        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
794        to always cumulate tile local-sum in the same order (still uses
795        MPI_Allreduce like standard code).
796      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
797        that are now identical to standard version (in eesupp/inc).
798    o pkg/shelfice:
799      - add SHELFICETransCoeffTFile for initializing spatially varying
800        heat and salt transfer coefficients
801    o pkg/atm_compon_interf & ocn_compon_interf:
802      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
803        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
804      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
805    o pkg/atm_ocn_coupler:
806      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
807    o pkg/rbcs:
808      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
809        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
810      - add a short report (to STDOUT) about RBCS-mask settings.
811    
812    checkpoint65p (2015/10/23)
813    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
814        there is no adjoint test for EVP, we don't know what it does to the adjoint
815        solution, but at least there are no more recomputation warnings left
816    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
817        a chance of giving the same results as a fully converged VP (JFNK) solver
818    o tools/adjoint_options/adjoint_diva:
819      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
820    o pkg/streamice:
821      - spotted bug in streamice_driving_stress using dyG where should have been dxG
822    o pkg/exf:
823      - remove STOP statement that prevented to use wind or (wind-)stress
824        interpolation for constant-in-time forcing fields (wind/stress period = 0).
825    o pkg/seaice:
826      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
827        5 additionals 2D fields and 6 new store directives
828      - change logic in seaice_readparms.F: EVP code can now be turned on in
829        various ways, setting SEAICE_deltaTev is no longer required,
830        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
831        or SEAICEaEVPcoeff
832    o pkg/shelfice/shelfice_thermodynamics.F
833      - redefining uLoc/vLoc to u/v, instead of 2u/v
834    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
835      - this is an intermediate state of a truely converging EVP that has
836        the potential of outperforming implicit VP methods, I do not recommend
837        using it yet.
838      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
839        and all parameters are hardwired
840      - for convergence it still requires very smooth regularisations, that means,
841        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
842        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
843        specific averaging appears to be required, still subject to tuning
844      - still needs cleaning and I need to turn parameter into runtime parameters
845      - add code to compute and print residuals of iteration, compile with
846        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
847    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
848      that entered with r1.54 on Sep04, 2015, -> update results
849    
850    checkpoint65o (2015/09/14)
851    o pkg/mom_vecinv & mom_common:
852      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
853        called from there.
854      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
855        allows to use Vector-Invariant form in deep atmos and anelastic formulation
856    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
857      and Koenig-Beatty+Holland (2012)
858      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
859      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
860      - requires an extra input argument for S/R seaice_calc_viscosities
861      - tensileStrength's depth dependence is different from Itkin et al. (2015)
862        (to be changed and played with, for now exponential)
863    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
864      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
865        by AREA according to Connelly et al. (2004), JPO.
866      - For EVP and the LSR solver, the implicit part of the drag term is
867        the only non-zero term in the denominator when there is no ice (which
868        prevented running the model with zero ice-ocean drag). If
869        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
870        (or zero main diagonals BU/BV) which need to be caught. A practical
871        consequence is that for open water, the momentum equation reduce
872        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
873        they happen to be zero, often leading to a non-zero solution over
874        open water.
875    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
876        efficient EVP method.
877      - introduce area-weighted averages for e12 (analogously to
878        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
879        remain, but also changing the order of terms in the previous average
880        changed the results as much) -> update experiment
881      - add SEAICE_DELTA_SMOOTHREG code
882      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
883        TEM-code
884      - adjust loop bounds so that only required fields are computed
885      - add new averaging code for zetaZ/deltaZ (again similar to
886        seaice_calc_viscosities.F), inactive by default for now (will change
887        results again), but will replace old code eventually
888    o eesupp/src:
889      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
890        to always cumulate tile local-sum in the same order
891        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
892        Still uses MPI_Allreduce (like standard code) but on array of tiles
893        and should be faster than GLOBAL_SUM_SEND_RECV code.
894      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
895        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
896      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
897         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
898         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
899         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
900         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
901    
902    checkpoint65n (2015/07/29)
903    o pkg/thsice:
904      - add a warning when used with pkg/aim but without updating SST
905        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
906    o pkg/offline:
907      - change where Offline-Fields are loaded, from load_fields_driver.F to
908        directly within FORWARD_STEP, just after updating iter number and time;
909      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
910        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
911       These changes allow:
912        a) to recover exactly on-line results using deltaToffline=deltaTClock,
913        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
914        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
915        time-step, both with GM & KPP files and with recomputing these fields;
916        b) no needs to switch on staggerTimeStep anymore;
917        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
918      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
919    o pkg/offline:
920      - change (rarely used) offset-iteration parameter to an offset time (in s):
921        can easily recover previous offset-iter effect by setting offset-time
922        (offlineTimeOffset) to offset-iter x deltaToffline;
923      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
924        in KPP as part of surface buoyancy forcing) in offline run.
925      - fix ptracers KPP non-local term in the case where KPP is re-computed.
926    o OpenAD
927      - Adding preliminary ggl90 test to OpenAD verification.
928        Config. with ggl90 currently diverges after 64 time steps
929        so will need more work to become more stable
930      - Adding preliminary kpp test to OpenAD verification.
931        required small tweakes in kpp_routines.F
932      - Merge and update from Krishna Narayanan's contrib area:
933        * Add one variable for preliminary OpenAD DIVA
934        * Add replacement time-stepping for OpenAD DIVA
935        * genmake2 flag -diva (but only for OpenAD; preliminary)
936        * required modifs for OAD_support
937        successful preliminary test for tutorial_global_oce_biogeo/
938    o pkg/seaice:
939      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
940      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
941        delta with a smooth function in s/r seaice_calc_viscosity
942        (no effect on EVP)
943      - rename local suffix "sqr" into "sq" for more consistent variable names
944    o pkg/seaice:
945        add new parameter SEAICE_deltaMin that is used ***only***
946        for regularizing Delta (and nothing else, like the parameter
947        which is also used for all sorts of things SEAICE_EPS).
948        Defaults to SEAICE_EPS for backward compatibility only.
949    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
950        the wrong key by inialising it before use -> fixes a recomputation
951        problem but does not fix the gradient
952    o pkg/layers:
953      - move resetting of flux arrays to outside the iLa loop
954        (this caused layers_diapycnal to not work with more than one layer coord.)
955      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
956    o pkg/layers:
957      - remove from common block 3D layers fields (used to diagnose transport
958        in tracer coords) and declare them as local arrays in layers_calc.F
959    o pkg/seaice:
960      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
961        in lab_sea forward experiment (changes results -> updated)
962      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
963    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
964       computations; for SEAICE_VECTORIZE_LSR
965      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
966        sweep to the outside,
967      - remove store directives and add "CADJ loop sequential" directives
968        in analogy to model/src/solve_tridiagonal.F
969      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
970        boundaries to yield more readable code. This has also the charming side
971        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
972        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
973        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
974        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
975        an additional option)
976       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
977       but the adjoint gradients (which are affected by this change) still explode.
978    o coupler (atm & ocn _compon_interf):
979      - avoid using Exch2 IO mapping if not suitable.
980    
981    checkpoint65m (2015/06/15)
982    o pkg/layers:
983      - clean-up old parameters setting (from Sep 2012):
984        + remove old parameters setting from common block (declared locally);
985        + stop if any old parameter is mixed with new parameters;
986        + check for valid or consistent parameter setting (e.g., layers_name)
987      - check that layers_bounds for Pot.Density are in the right range;
988        this is supposed to catch un-updated setting after recently shifting
989        potential density field "prho" by -1000 (now in "sigma" scale).
990    o pkg/layers:
991      - Added missing call to layers_fill for keeping track of tottend in
992        pkg/diagnostics/diagnostics_fill_state.F
993    o pkg/layers:
994      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
995        of diapycnal fluxes
996    o pkg/layers:
997      - reverted changes to interpolation to previous treatment; there
998        was never actually a problem
999    o pkg/layers:
1000      - fix interpolation of layers tracers in the presence of partial cells
1001      - add lots of new functionality to compute water mass transformation
1002        (enabled by CPP flag LAYERS_THERMODYNAMICS)
1003      - add new calls from main code (diags_oceanic_surf_flux.F,
1004        thermodynamics.F, impldiff.F) and gad to save the necessary fields
1005        for layers_thermodynamics calculations
1006    o pkg/ptracers:
1007      - add capability of stepping a passive tracer forward without advection
1008        by setting PTRACERS_advScheme to 0.
1009    o pkg/diagnostics:
1010      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
1011    o pkg/layers:
1012      - shift potential density field "prho" by -1000 for density layer averaging so
1013        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
1014        Note that density bin boundaries (layers_bounds in data.layers) have
1015        to be set accordingly (i.e., shifted, in sigma scale).
1016    o pkg/layers:
1017      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
1018      - fix calculation of layer non-weighted velocity and layer probability
1019      - add diagnostics for pot.density used for layer averaging
1020    o pkg/seaice:
1021      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
1022        positiveness, modify a few comments and improve variable names,
1023      - the changed computation of deltaC affects most seaice-related
1024        experiments at the truncation level.
1025        seaice_itd.thermo is affected by far the most, with
1026        only 7 digits of agreement remaining; update experiments.
1027    
1028    checkpoint65l (2015/05/04)
1029    o pkg/shelfice:
1030      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
1031        factor drKp1 to zero where it is negative (ie. do not use
1032        SHELFICEBoundaryLayer if hFacC>1)
1033      - the same for factor drLoc in shelfice_forcing.F
1034    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
1035        with modules in ptracers, when using testreport option "-small_f"
1036    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
1037      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
1038    o verification/testreport
1039      - add new option -small_f
1040        with this option testreport first makes the target small_f (*.f files)
1041        before running make (all). This is useful for explicit inlining when
1042        all sources need to be full available.
1043    o pkg/exf/exf_interp.F:
1044        remove previous changes related to reverse (decreasing) input grids latitude
1045    
1046    checkpoint65k (2015/04/01)
1047    o pkg/ecco:
1048        fix missing cosphi initialization; use eccoiter in place of optimcycle;
1049        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
1050        instead of active read/write
1051    o pkg/ctrl:
1052        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
1053        instead of active read/write.
1054    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
1055        return if .NOT.useAUTODIFF
1056    o pkg/seaice: add CPP brackets (cost function related).
1057    o model/src:
1058        add useAUTODIFF run time switch.
1059    o pkg/exf/exf_interp.F:
1060        add code to allow input grids with latitude starting in the north (i.e. when
1061        j=1 corresponds to northern edge of field); modify global_with_exf to test
1062        this feature.
1063    o verification/testreport:
1064      - replace "grep -A3" with POSIX conformal sed command, because there are
1065        implementations of grep that cannot do contextual searches
1066      - replace "cat -n" by "nl" (two occurrences), because not all implementations
1067        of "cat" have the option "-n"
1068    o model/src:
1069        add new file gsw_teos10.F that contains 3 functions, more or less a copy
1070        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
1071        convert from conservative to potential temperature. For now they are not
1072        called anywhere.
1073    o pkg/ggl90: make "useIDEMIX" useful
1074      - re-organize code in s/r ggl90_calc a little to move computations that
1075        are different for idemix into separate loops (changes verification
1076        experiment idemix at truncation level, 12 digits remain -> updated)
1077      - requires 2 new 2D fields KappaM, verticalShear
1078      - make hFacI and recip_hFacI local 3D variables that are passed to
1079        s/r ggl90_idemix
1080      - fix and improve some comments
1081    
1082    checkpoint65j (2015/02/25)
1083    o pkg/openad
1084      - synchronize seawater.F with version in model/src: replace routine
1085        body of sw_temp by calling sw_ptmp and fix/add a few comments.
1086    o pkg/mnc:
1087      - change default value of pickup_read/write_mnc params to FALSE
1088        (since few features are missing in reading MNC pickup files).
1089    o model/src:
1090      - change default (background) vertical diffusivity for salt to be the
1091        temperature (background) vertical diffusivity.
1092      - change background vertical diffusivity in vertical mixing pkgs ggl90,
1093        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
1094        This makes ptracers default diffusivity (that uses salt diffKr) more
1095        consistent with vertical mixing schemes.
1096    o verification/testreport:
1097      - fix typo in "-pcls" option ;
1098      - put temp files in /tmp (instead of in local dir)
1099      - add option "-ncad" to use genmake2 new option "-nocat4ad"
1100      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
1101    o pkg/ggl90 (idemix code):
1102      - apply few fixes ; add some missing "_d 0" ; update output of exp.
1103        global_ocean.90x40x15.idemix
1104    o OpenAD
1105      - enable active file I/O and begin removal of work-around code
1106        for OpenAD for handling control variables (memory vs. active files)
1107      - new CPP options file OPENAD_OPTIONS.h
1108      - revert to genarr2d gradient check for hs94.1x64x5
1109      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
1110      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
1111    o tools/genmake2:
1112      - add option for an alternative Makefile (from Martin) where multiple
1113        source files are sent to TAF (instead of all in one file).
1114    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
1115      - code provided by Carsten Eden as an extension of ggl90
1116      - so far the code is turned on within ggl90 by setting a CPP-flag at
1117        compile time; a runtime flag implementation is not yet complete
1118      - tested in new verification experiment global_ocean.90x40x15.idemix
1119    o verification:
1120      - reduce length of the AD test run by half for experiments
1121        global_ocean.cs32x15 (std + thsice) and isomip
1122      - enable active file I/O for OpenAD, adjust verifications accordingly
1123      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
1124    o verification/testreport:
1125      - fix two non-POSIX sed statements so that there are no error messages
1126        on Mac OS X
1127      - replace hostname -s with hostname | sed 's/\..*$//'
1128    o model/src/seawater.F:
1129      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
1130        (following the matlab code), which would have avoided the bug caught
1131        by Matt (see below) in the first place
1132    o pkg/shelfice:
1133      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
1134        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
1135      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
1136        ice-shelf case (i.e., within surface level).
1137      - add config summary in shelfice_check.F
1138      - remove global variable recip_SHELFICElatentHeat and replace by a local
1139        variable recip_latentHeat
1140      - introduce diagnostics for friction velocity uStar (in case of
1141        SHELFICEuseGammaFrict)
1142      - change verification experiment isomip.htd:
1143        + start from pickup (as input_ad at nIter0=8640)
1144        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
1145        + test SHELFICEuseGammaFrict = .TRUE.
1146        + test SHELFICEadvDiffHeatFlux = .TRUE.
1147    o model/src:
1148      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
1149        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
1150        update output of experiments global_with_exf.yearly and isomip (all 6).
1151    o pkg/shelfice:
1152      - change setting of kTopC to also be zero where there is no ice-shelf.
1153      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1154        ice-shelf is.
1155      - first attempt to get RealFreshWaterFlux effects: for now, only without
1156        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1157    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1158      for thermodynamic calculations
1159      - because of divisions of the type 7/7 not exactly equal to 1, this change
1160        affects results of some verification experiments by up to 4 digits:
1161        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1162        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1163        adjoint: lab_sea, lab_sea.noseaicedyn
1164        -> updated
1165    
1166    checkpoint65i (2015/01/23)
1167    o model/src:
1168      - change units of frictionHeating field from W to W/m^2
1169      - fix bug in frictional heating from stratospheric drag in
1170        S/R ATM_PHYS_TENDENCY_APPLY_V
1171      - with synchronous time-stepping: move resetting to zero of frictionHeating
1172        field from load_fields_driver.F to thermodynamics.F ;
1173      - add diagnostics for frictional heating.
1174    o model/src & gmredi K3D:
1175      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1176      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1177      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1178        and name in pickup file).
1179      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1180    o model/src:
1181      - move (from ini_forcing.F) initialisation of all arrays in header file
1182        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1183        (since Nov 2012) with option selectAddFluid=1.
1184    o pkg/shelfice:
1185      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1186      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1187    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1188    o pkg/seaice: two new runtime parameters:
1189      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1190        long overdue
1191      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1192        parameterization of tensil stress for fast ice (does not do anything yet)
1193    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1194        for LSR: move checking overlaps out of JFNK-if-block
1195    o pkg/atm_phys:
1196      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1197        new S/R ATM_PHYS_DYN2PHYS.
1198      - fix level height for Linear Free-Surf case (to be consistent with
1199        fixed-in-time pressure levels).
1200    o pkg/mom_common (bottomdrag):
1201      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1202        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1203        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1204    o pkg/shelfice (u/v_drag):
1205      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1206      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1207        (now similar to shelfice_u_drag.F)
1208      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1209        from mom_vecinv.F (similar to mom_fluxform calls).
1210    o pkg/mom_common (bottomdrag):
1211      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1212      - add options for alternative discretisation of velocity norm in quadratic
1213        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1214        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1215        improves when averaging only the other component (e.g. vVel for U bottom
1216        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1217      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1218        friction (no-slip BC) thus getting the true distance from the bottom;
1219        off by default since this also reduces model stability (explicit bottom
1220        friction). Changes produce different machine truncation with linear-drag
1221        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1222        front_relax (bvp & mxl, 10 & 11 digits).
1223    o model/src & mom pkgs:
1224      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1225        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1226      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1227        just copy level Nr value to level Nr+1.
1228    o doc:
1229      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1230    o pkg/shelfice:
1231      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1232        SHELFICE.h: move array shelficemass to init_varia, initialise
1233        from array shelficemassinit, which is set in init_fixed and
1234        has option to be set from file; introduce array
1235        shelficeMassDynTend array, set thru file in init_fixed
1236      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1237        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1238        pkg/streamice
1239      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1240        SHELFICEMassStepping = .true.
1241      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1242    
1243    checkpoint65h (2014/12/17)
1244    o verification/global_ocean.90x40x15, global_ocean_ebm:
1245      - update to generic controls.
1246    o pkg/ctrl:
1247      - ctrl_map_ini_genarr.F: test for igen>0
1248      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1249      - move gentim2d part of ctrl_map_ini_genarr.F to
1250        new separate routine : ctrl_map_ini_gentim2d.F
1251      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1252        add time variable weights and cyclic controls (time mean,
1253        seasonal cycle, etc) capabilities to gentim2d
1254    o pkg/ecco:
1255      - move reading of error, conversion to weights from
1256        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1257    o global_oce_llc90, cs32:
1258      - activte sbo.
1259      - CTRL_SIZE.h : add maxCtrlProc.
1260      - activate the new genctrl capabilities.
1261      - update following reorganization of global_oce_input_fields.tar.gz  
1262    o pkg/ctrl/ctrl_ad_diff.list:
1263      - add missing ctrl_init_rec.f
1264    o tools/OAD_support/keepOriginal:
1265      - add ctrl_init_rec.F
1266    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1267      - avoid recomputations of xx_gentim2d_dummy.
1268    o momentum diagnostics:
1269      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1270        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1271    o pkg/seaice/seaice_lsr.F:
1272      - fix computation of BU/BV, make sure they are non-zero, only necessary
1273        for cubed sphere exchanges and SEAICE_OLx/y>0.
1274        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1275    o verification/global_ocean.cs32x15/input.seaice
1276      - add test for strong implicit coupling and restricted addtive Schwarz
1277        methods for LSR
1278      - update results/output.seaice.txt
1279    o verification/tutorial_global_oce_biogeo:
1280      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1281        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1282        update output_adm,_oadm,_tlm.txt
1283    o pkg/dic:
1284      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1285      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1286        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1287    o verification/tutorial_global_oce_biogeo:
1288      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1289        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1290        update output_adm,_oadm,_tlm.txt
1291    o eesupp/src:
1292      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1293        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1294    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1295      LSR (following Hutchings et al. 2004)
1296      - introduce zetaZ as a global variable (requires adjustments in
1297        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1298        in seaice_calc_viscosities.F
1299      - new flag SEAICEuseStrImpCpl (default off)
1300      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1301        momentum equations
1302      - JFNK-solver (preconditioner) adjusted to allow using this method
1303        (where it does not have any positive effect)
1304    o pkg/seaice
1305      - add overlap for restrictive additive Schwartz method also to LSR, but
1306        turn it off by default (because it only seems to work for non-cubed
1307        sphere/llc topologies)
1308    o pkg/autodiff
1309      - add extra exchanges in addummy_in_steppging also for mnc output
1310    o pkg/seaice:
1311      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1312        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1313    o pkg/obcs:
1314      - add option to specify domain-connected piece Id along OB though files
1315        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1316      - modify obcs_diag_balance.F to process each connected-part separately;
1317        exclude OB where Id = 0 but keep the full divergence there (-> constant
1318        Psi along this portion of OB and all inflow derived from grad(Phi))
1319      - add example of OB-conect files in verification/so_box_biogeo/input.
1320    o pkg/diagnostics:
1321      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1322      a) use non zero matrix element across OB and solve for Phi 1 grid point
1323         outside OB (i.e, where tracer OBCS are applied).
1324      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1325         velocity across OB, spread it uniformly along the OB in the RHS.
1326    
1327    checkpoint65g (2014/11/19)
1328    o pkg/diagnostcis:
1329      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1330    o pkg/my82,pp81,kl10:
1331      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1332        field diffKr as background diffusivity to set minimum diffusivity value.
1333    o pkg/seaice:
1334      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1335        Bouillon et al 2013)
1336      - add SEAICE_evpAlpha/Beta to namelist
1337      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1338        involve trivial re-ordering of divisions/multiplications that should not
1339        have any effects, but ... they do change the results of lab_sea.hb87 so
1340        that only 2 digits of agreement remain, in line with the general
1341        instability/fragility of the evp-code. For now, I do not care and just
1342        update the verification experiment
1343    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1344      - remove xx_genarr2d_numsmooth etc
1345      - use xx_genarr2d_preproc etc instead
1346      - carry out smooth_correl2D at initialization stage rather than during
1347        time stepping.
1348      - get smoothOpNb from xx_gentim2d_preproc
1349    o global_oce_cs32 :
1350      - add test of generic ecco capabilities.
1351    o pkg/exf/exf_getsurfacefluxes.F :
1352      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1353    o pkg/ctrl,ecco :
1354      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1355        is defined.
1356    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1357    o model/src:
1358      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1359        diffusivity (background) is specified but ignored.
1360    o verification:
1361      - in testreport, convert hostname to lower case for default output dir name
1362    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1363    o pkg/dic: add modifications from Hajoon:
1364      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1365      - light attenuation: add self-shading effect by climatological Chlorophyll
1366        (read from file).
1367    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1368        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1369    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1370        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1371        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1372        approach where CPP_OPTIONS.h includes an omnipotent
1373        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1374    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1375        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1376    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
1377        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
1378        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
1379    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
1380      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
1381      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
1382      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
1383      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
1384    o pkg/ctrl,ecco,exf :
1385      - remove variables associated with NON-generic costs,
1386        unless ECCO_CTRL_DEPRECATED is defined.
1387      - remove NON-generic NON-obcs controls,
1388        unless ECCO_CTRL_DEPRECATED is defined.
1389    o pkg/ctrl : added ctrl_local_params.h
1390    o pkg/ecco : added ecco_local_params.h
1391    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
1392        experiments, which will progressively be removed once the
1393        experiments are revised to use only generic controls/costs.
1394    
1395    checkpoint65f (2014/10/13)
1396    o pkg/ctrl, ecco, seaice : minor changes in headers

1399    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
1400    o pkg/ecco: increase modularity and improve logic

1402        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
1403        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1404      - cost_gencal.F (new) : determine filnames and records.
1405      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1406      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1407        and exploit the above functions leading to more compact code.
1408      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1409      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1410        using_ers, using_gfo, using_mdt is now only defined within gencost)
1411    o pkg/ecco: extend generic cost capabilities
1412      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1413        capabilities via gencost_preproc (+ _c,_i,_r related params),
1414        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1415        gencost_outputlevel arguments to cost_generic
1416      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1417        and active_read, making room for gencost_preproc to take effect.
1418        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1419      - pkg/ecco/cost_generic.F :
1420        compute and store misfit maks*(model-data) in localdif that is
1421        then used in cost and for output, output misfit if outlev.GT.0
1422      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
1423        rather gencost_barfile for deciding whether to write barfile
1424      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
1425      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
1426        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
1427      - pkg/ecco/ecco_summary.F : report gencost variables
1428      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1429    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1430    o pkg/ecco: internal re-organization
1431      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1432        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1433        mv relevant variables definition from ecco_cost.h to ecco.h,
1434        make sure gencost routines only include ecco.h)
1435      - throughout : add missing CCP switches, rm unused variables,
1436        and rm un-necessary CPP switches
1437      - throughout gencost routines : replace modelstartdate with
1438        gencost_startdate when needed
1439      - cost_bp_read.F : use arguments, instead of common blocs
1440        so that it can be used also by (new) cost_gencost_bpv4.F
1441      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1442      - ecco_phys.F : compute etanFull
1443      - ecco_readparms.F : rename using_topex as using_tpj, add
1444        bpv4-grace to gencost list, initialize added parameters
1445      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1446    
1447    checkpoint65e (2014/09/28)
1448    o pkg/obcs:
1449      - replaced the just-added CPP options with run-time variables
1450        (see pkg/obcs/OBCS_PARAMS.h for details)
1451    o pkg/obcs:
1452      - add additional CPP options for sponge boundary layers
1453        (see pkg/obcs/OBCS_OPTIONS.h for details)
1454    o pkg/atm_phys:
1455      - implement simple (obliquity only, assuming circular planet orbit)
1456        seasonal cycle for incoming insolation ; used when run-time parameter
1457        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1458    o pkg/exf, pkg/ecco, pkg/ctrl:
1459      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1460      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
1461      - implement gentim2d for xx_tauu, xx_tauv
1462    o pkg/ctrl, pkg/ecco :
1463      - fix and complement the generic controls implementation
1464    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
1465        pkg/shelfice/shelfice_thermodynamics.F,
1466        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
1467        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1468      - add weight in CTRL_GET_GEN calls
1469    o pkg/ctrl :
1470      - ctrl_get_gen.F : add weight as input parameter, and apply
1471        it directly rather than using smooth_correl2Dw (to be retired).
1472      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1473    o pkg/ctrl :
1474      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1475        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1476      - re-activate ctrl_summary (call in ctrl_init.F)

1483      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1484    
1485    checkpoint65d (2014/09/15)
1486    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
1487      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
1488        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1489    o pkg/ctrl/ctrl_map_ini_genarr.F :
1490      - remove compilation failure
1491      - replace hard coded example
1492      - use ctrl_map_ini_gen2D, 3D
1493    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
1494      - on/off switch based upon xx_genarr2d_weight,3d
1495    o src/packages_init_variables.F :

1510      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1511    o ecco/ecco_ad_diff.list :
1512      - add ecco_init_varia.f
1513    o ecco/ecco_init_varia.F
1514      - new routine
1515    o pkg/streamice:
1516      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1517        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1518      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1519    o pkg/generic_advdiff:
1520      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1521    o pkg/exf:
1522      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1523         xxg_precip capability
1524      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1525    o pkg/ctrl:
1526      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1527    o model/src/load_fields_driver.F :
1528      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1529        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1530    o OpenAD verification experiments:
1531      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1532        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1533        for now, only in pkgs used in OpenAD verification experiments.
1534      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1535        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1536        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1537        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1538    o OpenAD verification tests:
1539      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1540      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1541        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1542      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1543        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1544    o model/src & generic_advdiff:
1545      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1546        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1547        dynamics requires valid tracer forcing only over tile interior but, for
1548        some diagnostics, may need to extend it over 1 point in tile halo region.
1549      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1550        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1551        setting in temp/salt/ptracer_integrate.F
1552    o pkg/dic:
1553      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1554        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1555        in gchem_forcing_sep.F
1556    o pkg/autodiff & obcs:
1557      - add storage of current OB values for U & V (was already done for T & S).
1558    
1559    checkpoint65c (2014/08/30)
1560    o pkg/dic:
1561      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1562        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1563        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1564    o verification:
1565      - new experiment testing OBCS and DIC pkgs, using params & output from
1566        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1567        passage: take OBCS from the last year of a 2 yrs simulation and initial
1568        conditions from t=1.yr while keeping the same forcing.
1569    o model/src:
1570      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1571        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1572    o pkg/diagnostics (Stats-Diags):
1573      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1574        a) refine region where stats are computed, excluding where arrhFac=0 ;
1575        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1576        c) extend regional stats over the region edges (for U or V pt location).
1577    o pkg/gchem:
1578      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1579        pkg/dic is currently changing/updating ptracers values beyond the OB).
1580    o verification (hs94):
1581      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1582        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1583        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1584        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1585    o pkg/ptracers:
1586      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1587        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1588      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1589        with AB-2 code (so that it get tested).
1590    o model/src:
1591      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1592        with AB-2 code (previously only available with AB-3 code).
1593        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1594        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1595        there, by calling CYCLE_AB_TRACER).
1596    o pkg/generic_advdiff:
1597      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1598        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1599        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1600        S/R temp/salt/ptracers_integrate.F
1601    o model/src & pkg/ptracers:
1602      - remove common block variables gT,gS (in DYNVARS.h), except when
1603         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1604      - remove common block variable gPtr.
1605    o model/src & pkgs:
1606      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1607         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1608         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1609         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1610      + change accordingly all calling S/R.
1611      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1612        in S/R temp/salt/ptracers_integrate.F
1613    o pkg/seaice:
1614      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1615        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1616      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1617        in seaice_lsr
1618      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1619        in s/r seaice_lsr_calc_coeffs
1620    o pkg/mdsio:
1621      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1622        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1623        too long (e.g., > MAX_LEN_FNAM/2 )
1624    
1625    checkpoint65b (2014/08/12)
1626    o pkg/matrix:
1627      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1628    o model/src:
1629      - fix initialisation of geothermalFile; compile geothermal-flux code in
1630        natl_box verification experiment.
1631    o model/src & pkg/down_slope:
1632      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1633      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1634        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1635        results at machine truncation level: update output of experiments
1636        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1637    o pkg/diagnostics (Stats-Diags):
1638      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1639        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1640        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1641        times (but Min,Max and StD are still wrong).
1642    o model/src:
1643      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1644        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1645    o model/src:
1646      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1647        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1648        arrays are already updated while adjustments (filters, conv.adjustment) are
1649        still applied later, in S/R TRACERS_CORRECTION_STEP.
1650    o model/src:
1651      - store in common bloc array "rhoInSitu" the virtual potential temperature
1652        anomaly that is used to compute geopotential: this make the atmos code
1653        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1654    o pkg/seaice/seaice_lsr.F
1655      - rename integer variable ilcall to ipass (that's what it is called
1656        in the residual diagnostics
1657      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1658        default) for improved non-linear convergence of the first few steps
1659      - adjust a few comments and add new ones to explain some of the store
1660        directives
1661    o pkg/generic_advdiff (& ptracers):
1662      - re-work the code to check for valid advection scheme and for minimum
1663        size of overlap (now stored in local common bloc in gad_advscheme.F)
1664    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1665      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1666      - add an auxilliary variable "bet" and fix store directives and keys in
1667        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1668        less exact gradients in my tests); but there are still
1669        recomputation warning (although gradients are sort of OK), when
1670        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1671        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1672      - update verification experiments lab_sea.
1673      - change some comments in S/R seaice_calc_viscosities
1674    o model/src:
1675      - if staggerTimeStep=T, always apply exchange to velocity field in
1676        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1677        (independent of using multi-dim advection or not); no effect on FWD run
1678        but affects AD results (at machine truncation level): update output of
1679        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1680        and isomip (oad: 12.d).
1681    o pkg/generic_advdiff:
1682      - stop if doAB_onGtGs is set to FALSE but ignored
1683      - refine warning related to stability of tracer time-stepping
1684        regarding internal wave dynamics.
1685      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1686        on staggerTimeStep & implicitIntGravWave (will now get a warning
1687        if potentially unstable).
1688    o pkg/kl10:
1689      - add new pkg "kl10" for mixing due to internal wave breaking, from
1690        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1691        (contribution from Jody Klymak), tested in verification experiment
1692        verification/internal_wave/input.kl10/
1693    o isomip experiment:
1694      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1695        (input.htd) and update the output.
1696    o cd_code experiments:
1697      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1698        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1699        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1700        update the corresponding output.
1701    o pkg/seaice:
1702      - reduce the number of include files and store directives in
1703        S/R seaice_lsr_tridiagu/v
1704      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1705        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1706        get rid off one store directive (a TAF bug?)
1707      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1708        S/R seaice_lsr_tridiagv to change the loop range for consistency
1709      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1710      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1711        S/R seaice_lsr_tridiagu/v (requires update of
1712        offline_exf_seaice/input.dyn_jfnk)
1713    
1714    checkpoint65a (2014/07/27)
1715    o model/src:
1716      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1717        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1718        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1719        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1720    o model/src:
1721      - collect momentum forcing tendency into local 2-D array (passed as argument
1722        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1723        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1724        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1725      - collect T & S forcing tendency into local 2-D array (passed as argument to
1726        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1727        affects results at machine truncation level (e.g., ocean: if using
1728        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1729        correction due to vertical advection).
1730      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1731        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1732        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1733        obcs_ctrl (ad & fwd grd @ 12 & 7).
1734    o pkg/ptracers & diagnostics:
1735      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1736        title (to avoid some unexpected truncation); sort out ptracers diags units.
1737      - collect ptracer forcing tendency into local 2-D array (passed as argument
1738        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1739    
1740    checkpoint65 (2014/07/18)
1741    o pkg/fizhi:
1742      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1743        affects results at machine truncation level. Update output of experiments
1744        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1745    o pkg/seaice: more clean up
1746      - rename TAF common block tapes to be more consistent and remove
1747        unnecessary duplicates
1748      - add store directives to remove more recomputations, but use smaller
1749        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1750        The idea behind this flag is to reduce the memory footprint when the
1751        adjoint of the LSR is not required. As of now, defining the flag
1752        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1753        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1754        For experiment offline_exf_seaice, this means on a linux box with gfortran
1755        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1756        this experiment):
1757        > size mitgcmuv_ad
1758        text    data        bss     dec        hex
1759        5100659 1216  220458952  225560827  d71c8fb
1760        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1761        but only a moderate increase of 36% for global_ocean.cs32x15:
1762        text    data        bss     dec        hex
1763        6695027 1648 1014578664 1021275339 3cdf6ccb
1764        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1765      - note: there are still recomputations in global_ocean.cs32x15 and
1766        offline_exf_seaice and the gradient agreement changes (gets a
1767        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1768      - in general, the AD gradients still are wrong
1769    o OpenAD
1770      - clean up code_oad/ directories somewhat by moving files
1771        dontCompile, dontTransform, keepOriginal to OAD_support/
1772    o model/src:
1773      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1774        (not currently tested): add dissipation terms before NLFS rescaling of
1775        tendencies (previously done after).
1776    o pkg/diagnostics:
1777      - write stats-diags in ascii file with more digits (same as in monitor).
1778    o pkg/down_slope:
1779      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1780        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1781    o model/src:
1782      - new file "apply_forcing.F" containing all the code previously in
1783        external_forcing.F, but with new argument list: pass, as new argument,
1784        the current level tendency array to update (instead of a direct update
1785        of the common bloc array). Change the corresponding calls.
1786      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1787        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1788    o pkg/seaice/seaice_lsr, a little bit of clean up
1789      - rearrange some code blocks, so that now all calculations for
1790        setting up the right-hand-sides done within one single block
1791        (I find that easier to read and understand)
1792      - rearrange freedrift-code to reduce the number of ifdefs
1793      - adjust some indentations and comments
1794    
1795    checkpoint64z (2014/07/10)
1796    o model/src and several pkgs:
1797      - change argument list of all S/R called from external_forcing.F and
1798        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1799        to pass, as argument, the current level tendency array to update
1800        (instead of a direct update of the common bloc array).
1801      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1802      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1803    o pkg/seaice/seaice_lsr.F
1804      - always initialize local arrays in seaice_lsr_tridiagu/v
1805      - add more local tapes to seaice_lsr_tridiagu/v
1806      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1807        keep it in bi/bj loop; this seems to be essential
1808      - gradients are still wrong but only by 4-7 orders of magnitude
1809        instead of 15 orders of magnitude, lab_sea improves a little
1810    o pkg/seaice
1811      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1812        generates unnecessary code in seaice_lsr_ad
1813      - add more store directives in seaice_lsr to avoid unnecessary code
1814        in seaice_lsr_ad
1815      - exclude some residual computations in seaice_lsr when
1816        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1817        in seaice_lsr_ad
1818      - add more storing, a new tape (model/src/the_main_loop.F) and
1819        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1820        and klockey should be checked by a specialist)
1821      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1822        and update lab_sea after previous changes in pkg/seaice below
1823    o pkg/autodiff:
1824      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1825        viscFacInAd : run time parameters allowing for adjoint switches
1826        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1827    o pkg/ecco:
1828      - introduce cost_gencost_boxmean.F that computes a box mean
1829        temperature (for use in adjoint sensitivity studies).
1830    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1831    o pkg/mom_common/mom_calc_visc.F:
1832      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1833    o pkg/seaice/seaice_summary.F:
1834      - statement for SEAICEadjMODE now in autodiff_readparms.F
1835    o pkg/seaice:
1836      - remove some store directives and add new ones in an effort to get
1837        finally rid off the recomputation warnings. This is successful
1838        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1839        defined (i.e. no extensive recomputation warnings left), but there
1840        are still too many recomputations on the solver iteration level
1841      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1842      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1843        SEAICE_SIZE.h
1844      - add a store directive in S/R seaice_calc_viscosities
1845    o pkg/seaice (ITD code):
1846      - fix definition of Hlimit for multi-threaded case
1847      - use double precision arithmetic to compute Hlimit: this affects results;
1848        update output of experiment seaice_itd.
1849    o replace content of verification/seaice_itd
1850      - instead of a 1D column use the configuration of offline_exf_seaice
1851        to test the ice thickness distribution code with ridging
1852      - this is a first shot at this experiment
1853      - change of some defaults of ridging parameters SEAICEhStar (from
1854        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1855        and lot of new comments.
1856    
1857    checkpoint64y (2014/06/20)
1858    o pkg/seaice/seaice_reg_ridge.F:
1859      - modify the regularization of very small volumes of ice; only check
1860        total volume HEFF, and do not apply correction to individual ice
1861        classes because that leads to funny patterns in the heat and fw-fluxes
1862        into the ocean. Adjust seaice_itd/results/output.txt
1863      - replace nITD by SEAICE_multDim in loop-ranges
1864    o pkg/exf:
1865      - add code to process the case field period = -12. with UV interpolation.
1866      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1867        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1868    o verification/global_with_exf:
1869      - switch all fields period to -12. (was previously untested) in input/data.exf
1870        (but keep secondary test ".yearly" unchanged); update the reference output.
1871    o pkg/cal:
1872      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1873    o pkg/exf:
1874      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1875        to replace logical switch "exf_verbose"
1876      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1877    o pkg/sbo:
1878      - update from Katherine Quinn: evaluate mass directly from density and SSH
1879        (budget using Finite Volume method) instead of from bottom pressure.
1880      - allow testreport to collect few selected SBO output ; tested in exp.
1881        global_ocean.90x40x15 (after updating the results, to include SBO output).
1882      - fix some multi-threading issues (in output part).
1883    o model/src & most packages:
1884      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1885      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1886        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1887        "data.{pkg}" exist ; and leave the S/R (return) just after.
1888      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1889        + call LAND_READPARMS from packages_readparms.F
1890    o pkg/seaice:
1891      - remove code that resets useThSice in S/R seaice_readparms and
1892        replace it by a warning in S/R seaice_check
1893      - remove parameter MULTDIM, replace with nITD and runtime
1894        parameter SEAICE_multDim (still hard-wired to nITD if
1895        SEAICE_ITD is defined)
1896    
1897    checkpoint64x (2014/05/24)
1898    o verification/lab_sea:
1899      - update adjoint and TLM output following changes to pkg/salt_plume
1900      - un-do the update after putting back local recip_Cp in few places.
1901    o pkg/salt_plume: modifications by An Nguyen:
1902      - add capability to do brine rejection (salt-plume) as function of
1903        volume+tracers (instead of only salinity tracer).
1904      - conserve volume by exchanging volume from each kLev to above to
1905        accommodate in-coming brine volume
1906      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1907      - switch KPP surf buoyancy due to brine forcing to 3-d
1908        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1909      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1910      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1911        in East/West Arctic.
1912    o pkg/sbo:
1913      - incorporate modifications from Katherine Quinn to enable the use of sbo
1914        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1915        output for future testreport verification (unfinished).
1916    o pkg/atm_phys:
1917      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1918        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1919        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1920    o pkg/seaice
1921      seaice_calc_ice_strength.F: modify expression to avoid divisions
1922        (affects truncation)
1923      seaice_do_ridging.F: clean up the insectarium
1924      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1925      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1926      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1927      - add some debugging information and error messages (warnings)
1928    o model/src: modifications relatd to atmosphere p*:
1929      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1930      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1931        of vertical profile tRef in geopotential background and anomaly.
1932      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1933        and pkg/atm_phys.
1934      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1935        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1936    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1937    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1938        not used right now, but can be used in BGC packages to fix conservation.
1939    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1940        other packages too.
1941    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1942        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1943    o model/src:
1944      - since we have several heat capacity (even in model/src), define "recip_Cp"
1945        as local variable (no longer in common block) to avoid any confusion.
1946      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1947    o pkg/exf:
1948      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1949        air density as function of air Temp, Humidity and atm pressure.
1950    
1951    checkpoint64w (2014/05/02)
1952    o verification:
1953      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1954        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1955        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1956        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1957        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1958    o model/src: for atmosphere in p* coords:
1959      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1960      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1961        but not yet activated.
1962    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1963      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1964      - this changes the results (but not for any verification experiment, because
1965        none tests this), but avoids having an extra field in the restart files
1966    o pkg/seaice: remove global variable TICE (not needed)
1967      - replace by TICES or local variable where necessary (cost_seaice_test,
1968        seaice_diagnostics_state)
1969      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1970      - use specific read/write routines for reading and writing individual leves
1971        of a multilevel field
1972    o pkg/ctrl & model/inc:
1973      - move additional anomaly fields of control vars (related to options:
1974         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1975        from DYNVARS.h into new header file: CTRL_FIELDS.h
1976    o pkg/seaice: some small modifications to the ridging code
1977      - make fw2ObyRidge a global variable and add the freshwater flux to
1978        seaice_growth
