4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/exf:
8      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
9      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
10        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
11        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
12      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
13        EXF_INIT_FLD) and update calls in exf_init_varia.F
14      - For now, for backward compatibility, keep a simplified version of S/Rs
15        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
16      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
17        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
18    o tools/genmake2:
19      - replace "bc -l" (only used once) by "expr" (already used).
20    o verification/global_ocean.cs32x15:
21      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
22        Note: exf setting (data.exf) can be compared to other exf secondary exp
23        "seaice" (kept with useCAL=T) which has same time dependent forcing.
24    
25    checkpoint66d (2017/02/13)
26    o pkg/exf:
27      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
28        early on (in packages_boot.F) to stress this change in pkg setting.
29      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
30    o model/src:
31      - move call to ecco_phys to end of time step; this may induce minor
32        cost function changes by shifting time averages by one time step
33        for some variables; this revision resulted in changed adjoint results
34        in MITgcm_contrib/verification_other/global_oce_cs32
35    o pkg/exf:
36      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
37        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
38        e.g. precip, are not available.
39    o pkg/flt:
40      - flt_init_varia.F: use pickupSuff if specified
41      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
42        intermediate, step towards completing pkg/exch2 support within pkg/flt;
43        ifdef DEVEL_FLT_EXCH2 then:
44        - flt_init_fixed.F: comment out stop
45        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
46        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
47        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
48        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
49    o tools/genmake2 & pkg/pkg_depend:
50      - define new type of pkg dependency rule ("=pkg_x"), less strict than
51        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
52        (-pkg_x in packages.conf).
53      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
54      - add "+cal" to dependency list of pkg/ecco (needed to compile).
55      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
56    o utils/matlab:
57      - adding ocean_basin routines for defining basin masks.
58    o pkg/exf:
59      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
60        arguments, allowing to check (and stop) if parameter setting of
61         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
62        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
63        for backward compatibility.
64      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
65        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
66    o pkg/bling (USE_EXFCO2 code):
67      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
68        by adding a call to S/R EXF_GETFFIELD_START.
69    o pkg/exf:
70      - allows to compile without pkg/cal (but disabled by current dependency
71        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
72        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
73        of {FLD}startdate1 & date2 ; consistency check not yet coded.
74    o verification/global_ocean.cs32x15:
75      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
76        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
77    o pkg/exf:
78      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
79        calculations); change FWD experiment global_ocean.cs32x15
80        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
81    o pkg/exf:
82      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
83         {FIELD}startdate to {FIELD}StartTime
84        Note: new name also fit better the content, i.e, a start time in second.
85    o eesupp/src:
86      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
87    o pkg/exf:
88      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
89        to allow to read-in Sensible & Latent Heat flux ;
90      - simplify pkg/exf main options:
91        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
92           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
93           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
94        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
95           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
96        3) improve options documentation in EXF_OPTIONS.h.
97    o pkg/ecco:
98      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
99        ecco_summary.F: add passive tracer cost functions to gencost;
100        m_ptracer and m_boxmean_ptracer
101    o pkg/ctrl:
102      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
103        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
104        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
105        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
106    o model/src:
107      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
108        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
109    o pkg/exf:
110      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
111        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
112    
113    checkpoint66c (2017/01/19)
114    o verification:
115      - add new option "-src" to testreport to only produce source code (*.f),
116        including taf output src code (if using '-adm'/'-tlm' option).
117    o pkg/exf:
118      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
119    o pkg/diagnostics:
120      - add run-time variable diagMdsDir to specify a subdirectory for
121        diagnostic output when mds is being used and mdsioLocalDir is not.
122    o pkg/mnc:
123      - mnc_utils.F: edit stop message
124    o pkg/autodiff:
125      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
126        add HAVE_SYSTEM bracket around system call to mkdir
127    o pkg/profiles:
128      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
129        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
130      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
131        add HAVE_SYSTEM bracket around system call to mkdir
132    o pkg/smooth:
133      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
134      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
135      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
136    o pkg/exf:
137      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
138        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
139        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
140      - summary: skip detailed field report if not used (empty file-name).
141    o tools/xmakedepend:
142      - In case line editor "ed" is missing, switch to "sed" command to clean-up
143        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
144    o pkg/exf:
145      - change definition of "hflux" input file to always include Short-Wave;
146        this is now consistent with hflux computation (if using bulk-formulae)
147        and hflux diagnostic & documentation (in EXF_FIELDS.h).
148    
149    checkpoint66b (2016/12/01)
150    o model & momentum pkgs:
151      - implement fully implicit bottom friction combined with implicit surf.
152        pressure, for now, only in hydrostic formulation:
153        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
154          and run with selectImplicitDrag=2 ;
155        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
156      - partial implicit time-stepping (bot. friction + vert. visc first, then
157        surf. press) corresponding to selectImplicitDrag=1 should be applicable
158        to NH formulation but not available until we solve for surf. pressure
159        increment (instead of full etaN).
160      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
161        with implicit vertical viscosity.
162    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
163      - this is a first version that includes many regularisations that may
164        not all be necessary, to be sorted out,
165      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
166      - change one verification experiment in seaice_itd to use and test new code
167      - seaice_growth: catch a case where the argument of log can be zero
168        or smaller (important for code stability)
169    o model/src:
170      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
171        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
172        similar A.X'=Y' system (with same matrix A) in subsequent calls;
173        switch based on errCode (In/Out) argument value; in calling routines,
174        initialise errCode before first call.
175    
176    checkpoint66a (2016/10/18)
177    o pkg/bling:
178      - BLING package now loads in atmospheric pCO2 file using exf package routines
179        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
180    o model/src & pkg/ptracers:
181      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
182        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
183        implicitDiffusion (respectively) are used (even without momImplVertAdv
184        or temp,salt,PTRACERS_ImplVertAdv).
185    o model/src & generic_advdiff:
186      - add parenthesis in main diagonal calculation of implicit vertical
187        diffusion matrix (impldiff.F & gad_implicit_r.F).
188        This affects results at machine truncation level; update output of many
189        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
190    o pkg/mom_commom & generic_advdiff:
191      - add deep atmosphere and anelastic scaling factor in implicit vertical
192        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
193    o model/src:
194      - remove few unnecessary temp array copies in solve_tridiagonal.F
195        & solve_pentadiagonal.F
196    
197    checkpoint65z (2016/09/28)
198    o pkg/seaice: fix multithreading for seaice_fgmres.F
199      - remove unecessary variables from common blocks
200      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
201        basis, that are stored in commom blocks (including integer variable i1)
202      - clean up code a little by removing commented lines that refer to
203        original code
204      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
205    o MITgcm manual:
206      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
207        preliminary documentation for generic controls (8.3; ctrl.tex),
208        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
209        ecco_costfunction.tex
210    o pkg/ecco:
211      - update and cleanup list of CCP options
212      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
213        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
214      - add checks that retired run-time options are not used, and in relation
215        to gencost_mask and gencost_errfile
216      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
217        gencost_nrecperiod
218      - fix m_eta computation for virtual salt flux case
219      - add m_horflux_vol case (selected via gencost_barfile) that computes
220        transports via cost_gencost_boxmean (gencost_flag=-3)
221      - use gencost_flag more systematically (i.e., avoid using gencost_name)
222        for code switches (aside from physical variable selection)
223    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
224      attempt appears to be a bit of a hack and my need some repair down the road
225    o pkg/exf:
226      - interpolation near South Pole: fix criteria on input field latitude.
227    o pkg/icefront & pkg/exf:
228      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
229        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
230    o pkg/exf:
231      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
232        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
233        (add suffix "_out" instead of a prefix); keep same record number as in
234        input file but always write record 1 first (to avoid a STOP in I/O S/R).
235        Change output file content by writing interpolated field before applying
236        land-sea mask (helpful for debug).
237      - 2 compon. vector interpolation with rotation: apply scaling factor on
238        each compon. (Eastward and Northward) just before rotation.
239    o pkg/bling:
240      - Cleaned package. Removed not needed code and comments.
241      - adjoint example now works
242        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
243    o pkg/ptracers:
244      - add Bruno Deremble's code to complete the linear surface correction
245        for tracer conservation;
246      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
247    
248    checkpoint65y (2016/07/29)
249    o pkg/debug (stats):
250      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
251        proc/thread mapping);
252      - fix Min & Max for case where 1 thread has only empty tiles;
253      - use RL variable to count number of wet grid points (with big domain,
254        can be too large to fit into integer*4).
255    o pkg/monitor:
256      - use RL variable to count number of wet grid points (but used only for del2)
257      - add new routine to compute Advective CFL within tracer time-stepping with
258        writing delayed until next monitor output.
259    o pkg/obcs:
260      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
261    o pkg/cal:
262      - calandar-dump: treat case myTime < timePhase in the same way as in
263        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
264    o pkg/dic & seaice:
265      - fix compilation of ocean component for coupled atm+ocn model with
266        seaice dynamics & dic.
267    
268    checkpoint65x (2016/06/11)
269    o add a license text file in main MITgcm tree.
270    o added pkg/bling:
271      - intermediate complexity biogeochemical model
272      - see bling_description.txt for details
273      - verification experiment is global_oce_biogeo_bling (for now, in
274        Contrib/verification_other/); tested daily on baudelaire with gfortran.
275      - add entry point in pkg/gchem for new pkg "bling".
276    o pkg/seaice: fix tensile stength computation
277      - replace global field tensileStrength by tensileStrFac
278      - tensileStrFac can be computed once in S/R seaice_init_varia
279      - fortunately that does not affect any verification results
280    
281    checkpoint65w (2016/05/12)
282    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
283         with ECCO_CTRL_DEPRECATED defined
284    o verification/global_ocean.cs32x15:
285      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
286        with "selectNHfreeSurf=1".
287    o model/src (non-hydrostatic free-surface):
288      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
289        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
290      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
291        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
292        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
293        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
294      - Update output (changes at machine truncation level) of verification exp:
295        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
296        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
297    o pkg/seaice: ITD code
298      - fix picking up from a single category model by initialising
299        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
300      - split a long warning message in seaice_check_pickup.F into two lines,
301        because NEC SX-ACE cannot deal with the long line.
302    o model/src:
303      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
304    o pkg/seaice:
305      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
306    o pkg/seaice:
307      - add basal stress as parameterisation for grounding ice
308        following Lemieux et al. (2015)
309      - turn on by setting new parameter SEAICEbasalDragK2 to a value
310        larger than 0. Lemieux et al. (2015) recommend 15.
311      - The adjoint complains with extra recomputations so there is also a
312        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
313        order to postpone the problem
314      - compile the new code in lab_sea
315    o verification/halfpipe_streamice:
316      - update both TAF and OpenAD adm output (machine truncation differences)
317    
318    checkpoint65v (2016/04/08)
319    o verification/advect_xz:
320      - increase overlap size from 3 to 4 and add new secondary test for PQM
321        advection scheme (with mono & wino limiter).
322      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
323    o model/src:
324      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
325        added phi0Ref) to set vertical axis origin and phiRef origin;
326        keep Ro_SeaLevel for backward compatibility (with a warning).
327       According to coordinate and fluid type:
328        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
329        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
330        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
331        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
332      - remove Ro_SeaLevel from ATM experiment parameter files;
333      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
334        complement; update output.txt (changes at machine truncation level).
335    o pkg/seaice/seaice_evp.F
336      - simplify computation of deltaZ and zetaZ to simple averaging following
337        Bouillon et al. (2013). This removes a lot of code, but also changes
338        verification experiment lab_sea.hb87 -> updated
339    
340    checkpoint65u (2016/03/14)
341    o pkg/generic_advdiff:
342      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
343        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
344        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
345        testing and not for actual use.
346    o model/src:
347      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
348        origin r = rF(1);
349      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
350        in EOS for height coordinate: enable to include NH Pressure or to use
351        more accurate pressure vertical profile; options not linked to EOS type
352        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
353      - start to implement variable gravity (along vertical): for now, only with
354        z-coords (not even z*).
355      - add Ideal Gas equation of state for height coordinate.
356      - update OpenAD output (affected at machine truncation level) of exp:
357        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
358    o pkg/exf:
359      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
360        of exf interpolation (before any rescaling, rotation or interpolation
361        to velocity point) for each field that gets loaded from file. This option
362        identically mimics the input file organization (e.g. record numbers in year
363        by year input files) besides the change in horizontal grid.
364      - add rotateStressOnAgrid run-time switch so that wind stress fields
365        can be provided on the A-grid in zonal/meridional direction and
366        rotated on the fly. This only applies to the case when the exf
367        interpolation is off and rotateStressOnAgrid is false by default.
368    o model/src:
369      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
370        it's also used with pkg/atm_phys) and add few more parameters (but still
371        inactive, src code yet to come)
372    
373    checkpoint65t (2016/02/10)
374    o pkg/atm_phys:
375      - from Ruth Geen: add optical depth dependence on CO2 concentration.
376    o model/src:
377      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
378        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
379        Update output of exp. deep_anelastic (changes at truncation level).
380    o tools:
381      - add a hack in "remove_comments_sed" (used only with TAF) for recent
382        version of OpenMPI (shipped with FC.23): comment out the new header
383        file "mpif-sizeof.h" which causes problems to TAF.
384    o pkg/seaice:
385      - change the termination criterion so that maxits (SEAICElinearIterMax)
386        has an effect
387      - unify iteration parameters for implicit solvers (JFNK and Picard)
388        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
389        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
390        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
391        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
392        SEAICEnonLinTol     replaces JFNKgamma_nonlin
393      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
394      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
395        use with SEAICEuseKrylov
396    o pkg/seaice/seaice_lsr.F
397        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
398        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
399        an effect.
400    o pkg/seaice: add two new parameters
401      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
402        parameter is not in any namelist)
403      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
404        a preconditioner for the non-linear Newton iteration of the JFNK
405        solver
406    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
407      affects some experiments at truncation level:
408      - global_ocean.cs32x15.icedyn (11 digits),
409      - global_ocean.cs32x15.seaice (11 digits),
410      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
411      - also update global_ocean.cs32x15 adjoint and tangent-linear results
412    o pkg/salt_plume & pkg/thsice:
413      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
414        connect salt_plume flux to ATM-OCN coupling pkgs interface:
415       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
416         export to coupler interface) even without compiling pkg/salt_plume ;
417       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
418         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
419    o pkg/dic:
420      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
421        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
422        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
423      - move also update with values from ATM-OCN Coupler in the same new S/R
424        (previously done in ocn_apply_import.F).
425    o tools/adjoint_options:
426      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
427        has been changed on Jan 14, 2016.
428    o pkg/ggl90:
429      - add alternative discretisation of vertical shear (off by default), to
430        compute the mean (@ grid-cell center) of vertical shear compon instead of
431        vertical shear of mean flow (@ grid-cell center).
432      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
433        results on adjacent faces of cubed-sphere grids; this fix the restart.
434    o pkg/atm_compon_interf:
435      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
436        pass last value, stored directly before export to CPL ;
437        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
438      - remove atmSLPr from pickup files (no longer needed for restart)
439    
440    checkpoint65s (2016/01/13)
441    o eesupp & genmake2:
442       - first check for Function ETIME and, if it fails, then check for subroutine
443         ETIME and consistent output; use the appropriate version in timers.F
444    o model/src:
445      - to check restart test, add option to apply EXCH to U,V earlier, just before
446        integr_continuity; turned off by default.
447    o pkg/dic:
448      - remove CPP option USE_ATMOSCO2 (not needed)
449    o tools/tst_2+2:
450      - try to ignore difference between +0 and -0 in binary file, causing test
451        to fail for no good reason.
452    o eesupp & genmake2:
453      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
454        but also check (in genmake2) that test runs and returns meaningful results.
455    o coupler pkgs:
456      Finish implementation of optionally-exchanged variable switches (started on
457       Nov 12) with addition of few more exchanged fields, including 2-way exchange
458       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
459       advection in OCN component; this requires sequential coupling.
460      coupler (pkg/atm_ocn_coupler):
461      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
462        routines (useful for debug).
463      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
464         flux, DIC fields) if corresponding switch is ON.
465      - add option to export RunOff to OCN (to use for DIC river input)
466      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
467      components (pkg/atm_ & ocn_compon_interf):
468      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
469        optionally exchanged fields; add a check & stop in cpl_readparms.F.
470        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
471        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
472      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
473        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
474      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
475      - hold in common block coupler optionally-exchanged variable switch
476        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
477      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
478        this is intended to replace the OCN cplFldtave.* output files (not updated
479        to contain new additional exchanged fields).
480    o pkg/dic:
481      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
482    o pkg/thsice:
483      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
484        and writing of thsice pickup files.
485    o pkg/atm_compon_interf:
486      - move all field individual export-call out of cpl_export_import_data.F
487        into new S/R ATM_EXPORT_FIELDS
488    o pkg/atm_compon_interf:
489      - store state variables (for now, only thSIce fields) just before beeing
490        exported (in cpl_export_import_data.F, like on ocean side) instead of from
491        atm_store_my_data.F like all exported fluxes.
492      - new version of pickup_cpl: write field names into meta file and read meta
493        file to find field postion in pickup. Also only write/read fields meeded for
494        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
495    o pkg/dic:
496      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
497    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
498        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
499        value can be from domain [0,1] to average between the two methods
500    o pkg/atm_phys:
501      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
502        hold fixed in time).
503    
504    checkpoint65r (2015/12/21)
505    o pkg/seaice:
506        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
507        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
508    o pkg/seaice:
509      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
510        when SEAICEscaleSurfStress=.TRUE.,
511      - apply areaW and areaS in S/R seaice_calc_lhs
512    o pkg/atm_phys:
513      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
514        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
515        for individual contribution (convection, LSC cond, radiation)
516      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
517        information); activated with: solar_exponent=0. and wv_exponent=-1.
518    o pkg/ggl90:
519      - within IDEMIX add upper limit for horizontal group velocity to
520        avoid instability problems in the explicit horizontal diffusion term for
521        long time steps or high resolution
522    o pkg/diagnostics:
523      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
524        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
525    o testreport:
526      - remove "-v" (verbose option) in default mpirun command.
527    o pkg/seaice/seaice_growth:
528      - catch potential division by zero in ITD code, does not change
529        verification results
530    o pkg/ecco:
531      - retire old codes to the Attic. The calls to retired functions are
532        left in a commented form in case they ever need to be re-activated.
533      - ecco_check.F: issue warning if any old CPP option is
534        defined that corresponds to retired codes -- then stop.
535    o pkg/atm_compon_interf:
536      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
537        coupler: use last time-step value instead of average over cplSendFrq_iter
538        time-step, similar to what is done for seaIceMass.
539        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
540    o eesupp & genmake2:
541      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
542        <= remove until a fix is found for some ifort version on ia32 machine.
543    o pkg/seaice/seaice_evp:
544      - refine residual computation
545    
546    checkpoint65q (2015/11/18)
547    o pkg/seaice/seaice_evp:
548      - fix residual computations so that they no longer affect the actual
549        simulation code
550      - fix seaice_readparams to be able to actually set new parameters
551        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
552    o model/src:
553      - fix wrong truncation (single prec) from "FLOAT" function in expressions
554        like: deltaT*FLOAT(myIter) when myIter is large:
555         a) replaced by DFLOAT (if not seen by TAF);
556         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
557    o pkg/aim_v23:
558      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
559        when pickupSuff is set ; do write rolling pickups + at the end of the run.
560    o pkg/atm_ocn_coupler + ocn_compon_interf:
561      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
562        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
563        add corresponding call in DO_OCEANIC_PHYS.
564    o coupler pkgs:
565      Start a new way to set-up optionally-exchanged variables (previously, only
566       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
567       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
568       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
569       compononent param default can be set accordingly).
570      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
571       but rather applies to a group a fields (going both ways like for DIC)
572       and corresponds to an option of coupling config.
573      coupler (pkg/atm_ocn_coupler):
574      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
575        and read namelist directly (without eessup S/R calls) instead of
576        in the very un-flexible old way, 1 param per line, in fixed order;
577      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
578        cleanly in CPL_CHECK_CPLCONFIG
579      - add new coupling-exchange selectors (some not yet active) including
580        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
581                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
582      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
583        component ; called directly from coupler.F, after comp. registrations;
584      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
585         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
586          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
587      components (pkg/atm_ & ocn_compon_interf):
588      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
589        CPP header file in all pkg source files.
590      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
591        ATM/OCN_CHECK_CPLCONFIG;
592      - add error-counter to track errors (e.g., in "data.cpl") and to stop
593        cleanly in ATM/OCN_CHECK_CPLCONFIG;
594      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
595        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
596        before PACKAGES_READPARMS;
597      verification/cpl_aim+ocn/:
598      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
599        "data.cpl" for coupler (in input_cpl).
600    o eesupp/inc:
601      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
602        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
603        to always cumulate tile local-sum in the same order (still uses
604        MPI_Allreduce like standard code).
605      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
606        that are now identical to standard version (in eesupp/inc).
607    o pkg/shelfice:
608      - add SHELFICETransCoeffTFile for initializing spatially varying
609        heat and salt transfer coefficients
610    o pkg/atm_compon_interf & ocn_compon_interf:
611      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
612        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
613      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
614    o pkg/atm_ocn_coupler:
615      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
616    o pkg/rbcs:
617      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
618        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
619      - add a short report (to STDOUT) about RBCS-mask settings.
620    
621    checkpoint65p (2015/10/23)
622    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
623        there is no adjoint test for EVP, we don't know what it does to the adjoint
624        solution, but at least there are no more recomputation warnings left
625    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
626        a chance of giving the same results as a fully converged VP (JFNK) solver
627    o tools/adjoint_options/adjoint_diva:
628      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
629    o pkg/streamice:
630      - spotted bug in streamice_driving_stress using dyG where should have been dxG
631    o pkg/exf:
632      - remove STOP statement that prevented to use wind or (wind-)stress
633        interpolation for constant-in-time forcing fields (wind/stress period = 0).
634    o pkg/seaice:
635      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
636        5 additionals 2D fields and 6 new store directives
637      - change logic in seaice_readparms.F: EVP code can now be turned on in
638        various ways, setting SEAICE_deltaTev is no longer required,
639        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
640        or SEAICEaEVPcoeff
641    o pkg/shelfice/shelfice_thermodynamics.F
642      - redefining uLoc/vLoc to u/v, instead of 2u/v
643    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
644      - this is an intermediate state of a truely converging EVP that has
645        the potential of outperforming implicit VP methods, I do not recommend
646        using it yet.
647      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
648        and all parameters are hardwired
649      - for convergence it still requires very smooth regularisations, that means,
650        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
651        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
652        specific averaging appears to be required, still subject to tuning
653      - still needs cleaning and I need to turn parameter into runtime parameters
654      - add code to compute and print residuals of iteration, compile with
655        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
656    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
657      that entered with r1.54 on Sep04, 2015, -> update results
658    
659    checkpoint65o (2015/09/14)
660    o pkg/mom_vecinv & mom_common:
661      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
662        called from there.
663      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
664        allows to use Vector-Invariant form in deep atmos and anelastic formulation
665    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
666      and Koenig-Beatty+Holland (2012)
667      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
668      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
669      - requires an extra input argument for S/R seaice_calc_viscosities
670      - tensileStrength's depth dependence is different from Itkin et al. (2015)
671        (to be changed and played with, for now exponential)
672    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
673      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
674        by AREA according to Connelly et al. (2004), JPO.
675      - For EVP and the LSR solver, the implicit part of the drag term is
676        the only non-zero term in the denominator when there is no ice (which
677        prevented running the model with zero ice-ocean drag). If
678        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
679        (or zero main diagonals BU/BV) which need to be caught. A practical
680        consequence is that for open water, the momentum equation reduce
681        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
682        they happen to be zero, often leading to a non-zero solution over
683        open water.
684    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
685        efficient EVP method.
686      - introduce area-weighted averages for e12 (analogously to
687        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
688        remain, but also changing the order of terms in the previous average
689        changed the results as much) -> update experiment
690      - add SEAICE_DELTA_SMOOTHREG code
691      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
692        TEM-code
693      - adjust loop bounds so that only required fields are computed
694      - add new averaging code for zetaZ/deltaZ (again similar to
695        seaice_calc_viscosities.F), inactive by default for now (will change
696        results again), but will replace old code eventually
697    o eesupp/src:
698      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
699        to always cumulate tile local-sum in the same order
700        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
701        Still uses MPI_Allreduce (like standard code) but on array of tiles
702        and should be faster than GLOBAL_SUM_SEND_RECV code.
703      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
704        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
705      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
706         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
707         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
708         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
709         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
710    
711    checkpoint65n (2015/07/29)
712    o pkg/thsice:
713      - add a warning when used with pkg/aim but without updating SST
714        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
715    o pkg/offline:
716      - change where Offline-Fields are loaded, from load_fields_driver.F to
717        directly within FORWARD_STEP, just after updating iter number and time;
718      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
719        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
720       These changes allow:
721        a) to recover exactly on-line results using deltaToffline=deltaTClock,
722        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
723        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
724        time-step, both with GM & KPP files and with recomputing these fields;
725        b) no needs to switch on staggerTimeStep anymore;
726        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
727      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
728    o pkg/offline:
729      - change (rarely used) offset-iteration parameter to an offset time (in s):
730        can easily recover previous offset-iter effect by setting offset-time
731        (offlineTimeOffset) to offset-iter x deltaToffline;
732      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
733        in KPP as part of surface buoyancy forcing) in offline run.
734      - fix ptracers KPP non-local term in the case where KPP is re-computed.
735    o OpenAD
736      - Adding preliminary ggl90 test to OpenAD verification.
737        Config. with ggl90 currently diverges after 64 time steps
738        so will need more work to become more stable
739      - Adding preliminary kpp test to OpenAD verification.
740        required small tweakes in kpp_routines.F
741      - Merge and update from Krishna Narayanan's contrib area:
742        * Add one variable for preliminary OpenAD DIVA
743        * Add replacement time-stepping for OpenAD DIVA
744        * genmake2 flag -diva (but only for OpenAD; preliminary)
745        * required modifs for OAD_support
746        successful preliminary test for tutorial_global_oce_biogeo/
747    o pkg/seaice:
748      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
749      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
750        delta with a smooth function in s/r seaice_calc_viscosity
751        (no effect on EVP)
752      - rename local suffix "sqr" into "sq" for more consistent variable names
753    o pkg/seaice:
754        add new parameter SEAICE_deltaMin that is used ***only***
755        for regularizing Delta (and nothing else, like the parameter
756        which is also used for all sorts of things SEAICE_EPS).
757        Defaults to SEAICE_EPS for backward compatibility only.
758    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
759        the wrong key by inialising it before use -> fixes a recomputation
760        problem but does not fix the gradient
761    o pkg/layers:
762      - move resetting of flux arrays to outside the iLa loop
763        (this caused layers_diapycnal to not work with more than one layer coord.)
764      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
765    o pkg/layers:
766      - remove from common block 3D layers fields (used to diagnose transport
767        in tracer coords) and declare them as local arrays in layers_calc.F
768    o pkg/seaice:
769      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
770        in lab_sea forward experiment (changes results -> updated)
771      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
772    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
773       computations; for SEAICE_VECTORIZE_LSR
774      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
775        sweep to the outside,
776      - remove store directives and add "CADJ loop sequential" directives
777        in analogy to model/src/solve_tridiagonal.F
778      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
779        boundaries to yield more readable code. This has also the charming side
780        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
781        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
782        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
783        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
784        an additional option)
785       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
786       but the adjoint gradients (which are affected by this change) still explode.
787    o coupler (atm & ocn _compon_interf):
788      - avoid using Exch2 IO mapping if not suitable.
789    
790    checkpoint65m (2015/06/15)
791    o pkg/layers:
792      - clean-up old parameters setting (from Sep 2012):
793        + remove old parameters setting from common block (declared locally);
794        + stop if any old parameter is mixed with new parameters;
795        + check for valid or consistent parameter setting (e.g., layers_name)
796      - check that layers_bounds for Pot.Density are in the right range;
797        this is supposed to catch un-updated setting after recently shifting
798        potential density field "prho" by -1000 (now in "sigma" scale).
799    o pkg/layers:
800      - Added missing call to layers_fill for keeping track of tottend in
801        pkg/diagnostics/diagnostics_fill_state.F
802    o pkg/layers:
803      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
804        of diapycnal fluxes
805    o pkg/layers:
806      - reverted changes to interpolation to previous treatment; there
807        was never actually a problem
808    o pkg/layers:
809      - fix interpolation of layers tracers in the presence of partial cells
810      - add lots of new functionality to compute water mass transformation
811        (enabled by CPP flag LAYERS_THERMODYNAMICS)
812      - add new calls from main code (diags_oceanic_surf_flux.F,
813        thermodynamics.F, impldiff.F) and gad to save the necessary fields
814        for layers_thermodynamics calculations
815    o pkg/ptracers:
816      - add capability of stepping a passive tracer forward without advection
817        by setting PTRACERS_advScheme to 0.
818    o pkg/diagnostics:
819      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
820    o pkg/layers:
821      - shift potential density field "prho" by -1000 for density layer averaging so
822        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
823        Note that density bin boundaries (layers_bounds in data.layers) have
824        to be set accordingly (i.e., shifted, in sigma scale).
825    o pkg/layers:
826      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
827      - fix calculation of layer non-weighted velocity and layer probability
828      - add diagnostics for pot.density used for layer averaging
829    o pkg/seaice:
830      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
831        positiveness, modify a few comments and improve variable names,
832      - the changed computation of deltaC affects most seaice-related
833        experiments at the truncation level.
834        seaice_itd.thermo is affected by far the most, with
835        only 7 digits of agreement remaining; update experiments.
836    
837    checkpoint65l (2015/05/04)
838    o pkg/shelfice:
839      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
840        factor drKp1 to zero where it is negative (ie. do not use
841        SHELFICEBoundaryLayer if hFacC>1)
842      - the same for factor drLoc in shelfice_forcing.F
843    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
844        with modules in ptracers, when using testreport option "-small_f"
845    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
846      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
847    o verification/testreport
848      - add new option -small_f
849        with this option testreport first makes the target small_f (*.f files)
850        before running make (all). This is useful for explicit inlining when
851        all sources need to be full available.
852    o pkg/exf/exf_interp.F:
853        remove previous changes related to reverse (decreasing) input grids latitude
854    
855    checkpoint65k (2015/04/01)
856    o pkg/ecco:
857        fix missing cosphi initialization; use eccoiter in place of optimcycle;
858        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
859        instead of active read/write
860    o pkg/ctrl:
861        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
862        instead of active read/write.
863    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
864        return if .NOT.useAUTODIFF
865    o pkg/seaice: add CPP brackets (cost function related).
866    o model/src:
867        add useAUTODIFF run time switch.
868    o pkg/exf/exf_interp.F:
869        add code to allow input grids with latitude starting in the north (i.e. when
870        j=1 corresponds to northern edge of field); modify global_with_exf to test
871        this feature.
872    o verification/testreport:
873      - replace "grep -A3" with POSIX conformal sed command, because there are
874        implementations of grep that cannot do contextual searches
875      - replace "cat -n" by "nl" (two occurrences), because not all implementations
876        of "cat" have the option "-n"
877    o model/src:
878        add new file gsw_teos10.F that contains 3 functions, more or less a copy
879        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
880        convert from conservative to potential temperature. For now they are not
881        called anywhere.
882    o pkg/ggl90: make "useIDEMIX" useful
883      - re-organize code in s/r ggl90_calc a little to move computations that
884        are different for idemix into separate loops (changes verification
885        experiment idemix at truncation level, 12 digits remain -> updated)
886      - requires 2 new 2D fields KappaM, verticalShear
887      - make hFacI and recip_hFacI local 3D variables that are passed to
888        s/r ggl90_idemix
889      - fix and improve some comments
890    
891    checkpoint65j (2015/02/25)
892    o pkg/openad
893      - synchronize seawater.F with version in model/src: replace routine
894        body of sw_temp by calling sw_ptmp and fix/add a few comments.
895    o pkg/mnc:
896      - change default value of pickup_read/write_mnc params to FALSE
897        (since few features are missing in reading MNC pickup files).
898    o model/src:
899      - change default (background) vertical diffusivity for salt to be the
900        temperature (background) vertical diffusivity.
901      - change background vertical diffusivity in vertical mixing pkgs ggl90,
902        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
903        This makes ptracers default diffusivity (that uses salt diffKr) more
904        consistent with vertical mixing schemes.
905    o verification/testreport:
906      - fix typo in "-pcls" option ;
907      - put temp files in /tmp (instead of in local dir)
908      - add option "-ncad" to use genmake2 new option "-nocat4ad"
909      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
910    o pkg/ggl90 (idemix code):
911      - apply few fixes ; add some missing "_d 0" ; update output of exp.
912        global_ocean.90x40x15.idemix
913    o OpenAD
914      - enable active file I/O and begin removal of work-around code
915        for OpenAD for handling control variables (memory vs. active files)
916      - new CPP options file OPENAD_OPTIONS.h
917      - revert to genarr2d gradient check for hs94.1x64x5
918      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
919      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
920    o tools/genmake2:
921      - add option for an alternative Makefile (from Martin) where multiple
922        source files are sent to TAF (instead of all in one file).
923    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
924      - code provided by Carsten Eden as an extension of ggl90
925      - so far the code is turned on within ggl90 by setting a CPP-flag at
926        compile time; a runtime flag implementation is not yet complete
927      - tested in new verification experiment global_ocean.90x40x15.idemix
928    o verification:
929      - reduce length of the AD test run by half for experiments
930        global_ocean.cs32x15 (std + thsice) and isomip
931      - enable active file I/O for OpenAD, adjust verifications accordingly
932      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
933    o verification/testreport:
934      - fix two non-POSIX sed statements so that there are no error messages
935        on Mac OS X
936      - replace hostname -s with hostname | sed 's/\..*$//'
937    o model/src/seawater.F:
938      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
939        (following the matlab code), which would have avoided the bug caught
940        by Matt (see below) in the first place
941    o pkg/shelfice:
942      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
943        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
944      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
945        ice-shelf case (i.e., within surface level).
946      - add config summary in shelfice_check.F
947      - remove global variable recip_SHELFICElatentHeat and replace by a local
948        variable recip_latentHeat
949      - introduce diagnostics for friction velocity uStar (in case of
950        SHELFICEuseGammaFrict)
951      - change verification experiment isomip.htd:
952        + start from pickup (as input_ad at nIter0=8640)
953        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
954        + test SHELFICEuseGammaFrict = .TRUE.
955        + test SHELFICEadvDiffHeatFlux = .TRUE.
956    o model/src:
957      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
958        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
959        update output of experiments global_with_exf.yearly and isomip (all 6).
960    o pkg/shelfice:
961      - change setting of kTopC to also be zero where there is no ice-shelf.
962      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
963        ice-shelf is.
964      - first attempt to get RealFreshWaterFlux effects: for now, only without
965        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
966    o pkg/seaice: add the option to prescribe a fixed thickness PDF
967      for thermodynamic calculations
968      - because of divisions of the type 7/7 not exactly equal to 1, this change
969        affects results of some verification experiments by up to 4 digits:
970        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
971        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
972        adjoint: lab_sea, lab_sea.noseaicedyn
973        -> updated
974    
975    checkpoint65i (2015/01/23)
976    o model/src:
977      - change units of frictionHeating field from W to W/m^2
978      - fix bug in frictional heating from stratospheric drag in
979        S/R ATM_PHYS_TENDENCY_APPLY_V
980      - with synchronous time-stepping: move resetting to zero of frictionHeating
981        field from load_fields_driver.F to thermodynamics.F ;
982      - add diagnostics for frictional heating.
983    o model/src & gmredi K3D:
984      - add frictionHeating field to pickup-files (for synchronous time-stepping)
985      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
986      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
987        and name in pickup file).
988      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
989    o model/src:
990      - move (from ini_forcing.F) initialisation of all arrays in header file
991        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
992        (since Nov 2012) with option selectAddFluid=1.
993    o pkg/shelfice:
994      - change units (+ document) of newly added field "shelfIceMassDynTendency"
995      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
996    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
997    o pkg/seaice: two new runtime parameters:
998      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
999        long overdue
1000      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1001        parameterization of tensil stress for fast ice (does not do anything yet)
1002    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1003        for LSR: move checking overlaps out of JFNK-if-block
1004    o pkg/atm_phys:
1005      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1006        new S/R ATM_PHYS_DYN2PHYS.
1007      - fix level height for Linear Free-Surf case (to be consistent with
1008        fixed-in-time pressure levels).
1009    o pkg/mom_common (bottomdrag):
1010      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1011        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1012        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1013    o pkg/shelfice (u/v_drag):
1014      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1015      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1016        (now similar to shelfice_u_drag.F)
1017      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1018        from mom_vecinv.F (similar to mom_fluxform calls).
1019    o pkg/mom_common (bottomdrag):
1020      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1021      - add options for alternative discretisation of velocity norm in quadratic
1022        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1023        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1024        improves when averaging only the other component (e.g. vVel for U bottom
1025        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1026      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1027        friction (no-slip BC) thus getting the true distance from the bottom;
1028        off by default since this also reduces model stability (explicit bottom
1029        friction). Changes produce different machine truncation with linear-drag
1030        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1031        front_relax (bvp & mxl, 10 & 11 digits).
1032    o model/src & mom pkgs:
1033      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1034        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1035      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1036        just copy level Nr value to level Nr+1.
1037    o doc:
1038      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1039    o pkg/shelfice:
1040      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1041        SHELFICE.h: move array shelficemass to init_varia, initialise
1042        from array shelficemassinit, which is set in init_fixed and
1043        has option to be set from file; introduce array
1044        shelficeMassDynTend array, set thru file in init_fixed
1045      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1046        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1047        pkg/streamice
1048      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1049        SHELFICEMassStepping = .true.
1050      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1051    
1052    checkpoint65h (2014/12/17)
1053    o verification/global_ocean.90x40x15, global_ocean_ebm:
1054      - update to generic controls.
1055    o pkg/ctrl:
1056      - ctrl_map_ini_genarr.F: test for igen>0
1057      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1058      - move gentim2d part of ctrl_map_ini_genarr.F to
1059        new separate routine : ctrl_map_ini_gentim2d.F
1060      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1061        add time variable weights and cyclic controls (time mean,
1062        seasonal cycle, etc) capabilities to gentim2d
1063    o pkg/ecco:
1064      - move reading of error, conversion to weights from
1065        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1066    o global_oce_llc90, cs32:
1067      - activte sbo.
1068      - CTRL_SIZE.h : add maxCtrlProc.
1069      - activate the new genctrl capabilities.
1070      - update following reorganization of global_oce_input_fields.tar.gz  
1071    o pkg/ctrl/ctrl_ad_diff.list:
1072      - add missing ctrl_init_rec.f
1073    o tools/OAD_support/keepOriginal:
1074      - add ctrl_init_rec.F
1075    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1076      - avoid recomputations of xx_gentim2d_dummy.
1077    o momentum diagnostics:
1078      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1079        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1080    o pkg/seaice/seaice_lsr.F:
1081      - fix computation of BU/BV, make sure they are non-zero, only necessary
1082        for cubed sphere exchanges and SEAICE_OLx/y>0.
1083        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1084    o verification/global_ocean.cs32x15/input.seaice
1085      - add test for strong implicit coupling and restricted addtive Schwarz
1086        methods for LSR
1087      - update results/output.seaice.txt
1088    o verification/tutorial_global_oce_biogeo:
1089      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1090        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1091        update output_adm,_oadm,_tlm.txt
1092    o pkg/dic:
1093      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1094      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1095        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1096    o verification/tutorial_global_oce_biogeo:
1097      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1098        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1099        update output_adm,_oadm,_tlm.txt
1100    o eesupp/src:
1101      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1102        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1103    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1104      LSR (following Hutchings et al. 2004)
1105      - introduce zetaZ as a global variable (requires adjustments in
1106        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1107        in seaice_calc_viscosities.F
1108      - new flag SEAICEuseStrImpCpl (default off)
1109      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1110        momentum equations
1111      - JFNK-solver (preconditioner) adjusted to allow using this method
1112        (where it does not have any positive effect)
1113    o pkg/seaice
1114      - add overlap for restrictive additive Schwartz method also to LSR, but
1115        turn it off by default (because it only seems to work for non-cubed
1116        sphere/llc topologies)
1117    o pkg/autodiff
1118      - add extra exchanges in addummy_in_steppging also for mnc output
1119    o pkg/seaice:
1120      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1121        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1122    o pkg/obcs:
1123      - add option to specify domain-connected piece Id along OB though files
1124        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1125      - modify obcs_diag_balance.F to process each connected-part separately;
1126        exclude OB where Id = 0 but keep the full divergence there (-> constant
1127        Psi along this portion of OB and all inflow derived from grad(Phi))
1128      - add example of OB-conect files in verification/so_box_biogeo/input.
1129    o pkg/diagnostics:
1130      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1131      a) use non zero matrix element across OB and solve for Phi 1 grid point
1132         outside OB (i.e, where tracer OBCS are applied).
1133      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1134         velocity across OB, spread it uniformly along the OB in the RHS.
1135    
1136    checkpoint65g (2014/11/19)
1137    o pkg/diagnostcis:
1138      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1139    o pkg/my82,pp81,kl10:
1140      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1141        field diffKr as background diffusivity to set minimum diffusivity value.
1142    o pkg/seaice:
1143      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1144        Bouillon et al 2013)
1145      - add SEAICE_evpAlpha/Beta to namelist
1146      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1147        involve trivial re-ordering of divisions/multiplications that should not
1148        have any effects, but ... they do change the results of lab_sea.hb87 so
1149        that only 2 digits of agreement remain, in line with the general
1150        instability/fragility of the evp-code. For now, I do not care and just
1151        update the verification experiment
1152    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1153      - remove xx_genarr2d_numsmooth etc
1154      - use xx_genarr2d_preproc etc instead
1155      - carry out smooth_correl2D at initialization stage rather than during
1156        time stepping.
1157      - get smoothOpNb from xx_gentim2d_preproc
1158    o global_oce_cs32 :
1159      - add test of generic ecco capabilities.
1160    o pkg/exf/exf_getsurfacefluxes.F :
1161      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1162    o pkg/ctrl,ecco :
1163      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1164        is defined.
1165    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1166    o model/src:
1167      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1168        diffusivity (background) is specified but ignored.
1169    o verification:
1170      - in testreport, convert hostname to lower case for default output dir name
1171    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1172    o pkg/dic: add modifications from Hajoon:
1173      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1174      - light attenuation: add self-shading effect by climatological Chlorophyll
1175        (read from file).
1176    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1177        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1178    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1179        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1180        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1181        approach where CPP_OPTIONS.h includes an omnipotent
1182        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1183    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1184        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1185    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
1186        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
1187        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
1188    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
1189      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
1190      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
1191      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
1192      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
1193    o pkg/ctrl,ecco,exf :
1194      - remove variables associated with NON-generic costs,
1195        unless ECCO_CTRL_DEPRECATED is defined.
1196      - remove NON-generic NON-obcs controls,
1197        unless ECCO_CTRL_DEPRECATED is defined.
1198    o pkg/ctrl : added ctrl_local_params.h
1199    o pkg/ecco : added ecco_local_params.h
1200    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
1201        experiments, which will progressively be removed once the
1202        experiments are revised to use only generic controls/costs.
1203    
1204    checkpoint65f (2014/10/13)
1205    o pkg/ctrl, ecco, seaice : minor changes in headers
1206    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
1207        cost function and control capabilities added since checkpoint65c.
1208    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
1209    o pkg/ecco: increase modularity and improve logic
1210      - ecco_toolbox.F (new) : basic operations that are often used,
1211        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
1212        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1213      - cost_gencal.F (new) : determine filnames and records.
1214      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1215      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1216        and exploit the above functions leading to more compact code.
1217      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1218      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1219        using_ers, using_gfo, using_mdt is now only defined within gencost)
1220    o pkg/ecco: extend generic cost capabilities
1221      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1222        capabilities via gencost_preproc (+ _c,_i,_r related params),
1223        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1224        gencost_outputlevel arguments to cost_generic
1225      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1226        and active_read, making room for gencost_preproc to take effect.
1227        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1228      - pkg/ecco/cost_generic.F :
1229        compute and store misfit maks*(model-data) in localdif that is
1230        then used in cost and for output, output misfit if outlev.GT.0
1231      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
1232        rather gencost_barfile for deciding whether to write barfile
1233      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
1234      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
1235        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
1236      - pkg/ecco/ecco_summary.F : report gencost variables
1237      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1238    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1239    o pkg/ecco: internal re-organization
1240      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1241        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1242        mv relevant variables definition from ecco_cost.h to ecco.h,
1243        make sure gencost routines only include ecco.h)
1244      - throughout : add missing CCP switches, rm unused variables,
1245        and rm un-necessary CPP switches
1246      - throughout gencost routines : replace modelstartdate with
1247        gencost_startdate when needed
1248      - cost_bp_read.F : use arguments, instead of common blocs
1249        so that it can be used also by (new) cost_gencost_bpv4.F
1250      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1251      - ecco_phys.F : compute etanFull
1252      - ecco_readparms.F : rename using_topex as using_tpj, add
1253        bpv4-grace to gencost list, initialize added parameters
1254      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1255    
1256    checkpoint65e (2014/09/28)
1257    o pkg/obcs:
1258      - replaced the just-added CPP options with run-time variables
1259        (see pkg/obcs/OBCS_PARAMS.h for details)
1260    o pkg/obcs:
1261      - add additional CPP options for sponge boundary layers
1262        (see pkg/obcs/OBCS_OPTIONS.h for details)
1263    o pkg/atm_phys:
1264      - implement simple (obliquity only, assuming circular planet orbit)
1265        seasonal cycle for incoming insolation ; used when run-time parameter
1266        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1267    o pkg/exf, pkg/ecco, pkg/ctrl:
1268      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1269      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip

1277      - add weight in CTRL_GET_GEN calls
1278    o pkg/ctrl :
1279      - ctrl_get_gen.F : add weight as input parameter, and apply

1281      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1282    o pkg/ctrl :
1283      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1284        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1285      - re-activate ctrl_summary (call in ctrl_init.F)
1286    o pkg/ctrl/ctrl_cost_gen.F :
1287      - fix CCP brackets, remove un-necessary myiter, mytime
1288    o pkg/ecco, pkg/ctrl :

1290      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
1291      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
1292      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1293    
1294    checkpoint65d (2014/09/15)
1295    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :

1303      - on/off switch based upon xx_genarr2d_weight,3d
1304    o src/packages_init_variables.F :
1305      - regroup pkg/estimation calls
1306      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1307        (moved to ctrl_init_variables)

1313      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
1314    o ctrl/ctrl_map_ini.F :
1315      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
1316        (moved to ctrl_init_variables)
1317    o ctrl/ctrl_map_ini_ecco.F :
1318      - remove ECCO_PHYS (mv to ecco_init_varia)
1319      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1320    o ecco/ecco_ad_diff.list :
1321      - add ecco_init_varia.f
1322    o ecco/ecco_init_varia.F
1323      - new routine
1324    o pkg/streamice:
1325      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1326        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1327      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1328    o pkg/generic_advdiff:
1329      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1330    o pkg/exf:

1336    o model/src/load_fields_driver.F :
1337      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1338        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1339    o OpenAD verification experiments:
1340      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1341        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1342        for now, only in pkgs used in OpenAD verification experiments.
1343      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1344        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1345        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1346        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1347    o OpenAD verification tests:
1348      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1349      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1350        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1351      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1352        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1353    o model/src & generic_advdiff:
1354      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1355        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1356        dynamics requires valid tracer forcing only over tile interior but, for
1357        some diagnostics, may need to extend it over 1 point in tile halo region.
1358      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1359        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1360        setting in temp/salt/ptracer_integrate.F
1361    o pkg/dic:
1362      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1363        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1364        in gchem_forcing_sep.F
1365    o pkg/autodiff & obcs:
1366      - add storage of current OB values for U & V (was already done for T & S).
1367    
1368    checkpoint65c (2014/08/30)
1369    o pkg/dic:
1370      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1371        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1372        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1373    o verification:
1374      - new experiment testing OBCS and DIC pkgs, using params & output from
1375        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1376        passage: take OBCS from the last year of a 2 yrs simulation and initial
1377        conditions from t=1.yr while keeping the same forcing.
1378    o model/src:
1379      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1380        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1381    o pkg/diagnostics (Stats-Diags):
1382      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1383        a) refine region where stats are computed, excluding where arrhFac=0 ;
1384        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1385        c) extend regional stats over the region edges (for U or V pt location).
1386    o pkg/gchem:
1387      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1388        pkg/dic is currently changing/updating ptracers values beyond the OB).
1389    o verification (hs94):
1390      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1391        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1392        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1393        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1394    o pkg/ptracers:
1395      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1396        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1397      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1398        with AB-2 code (so that it get tested).
1399    o model/src:
1400      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1401        with AB-2 code (previously only available with AB-3 code).
1402        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1403        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1404        there, by calling CYCLE_AB_TRACER).
1405    o pkg/generic_advdiff:
1406      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1407        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1408        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1409        S/R temp/salt/ptracers_integrate.F
1410    o model/src & pkg/ptracers:
1411      - remove common block variables gT,gS (in DYNVARS.h), except when
1412         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1413      - remove common block variable gPtr.
1414    o model/src & pkgs:
1415      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1416         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1417         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1418         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1419      + change accordingly all calling S/R.
1420      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1421        in S/R temp/salt/ptracers_integrate.F
1422    o pkg/seaice:
1423      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1424        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1425      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1426        in seaice_lsr
1427      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1428        in s/r seaice_lsr_calc_coeffs
1429    o pkg/mdsio:
1430      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1431        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1432        too long (e.g., > MAX_LEN_FNAM/2 )
1433    
1434    checkpoint65b (2014/08/12)
1435    o pkg/matrix:
1436      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1437    o model/src:
1438      - fix initialisation of geothermalFile; compile geothermal-flux code in
1439        natl_box verification experiment.
1440    o model/src & pkg/down_slope:
1441      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1442      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1443        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1444        results at machine truncation level: update output of experiments
1445        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1446    o pkg/diagnostics (Stats-Diags):
1447      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1448        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1449        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1450        times (but Min,Max and StD are still wrong).
1451    o model/src:
1452      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1453        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1454    o model/src:
1455      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1456        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1457        arrays are already updated while adjustments (filters, conv.adjustment) are
1458        still applied later, in S/R TRACERS_CORRECTION_STEP.
1459    o model/src:
1460      - store in common bloc array "rhoInSitu" the virtual potential temperature
1461        anomaly that is used to compute geopotential: this make the atmos code
1462        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1463    o pkg/seaice/seaice_lsr.F
1464      - rename integer variable ilcall to ipass (that's what it is called
1465        in the residual diagnostics
1466      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1467        default) for improved non-linear convergence of the first few steps
1468      - adjust a few comments and add new ones to explain some of the store
1469        directives
1470    o pkg/generic_advdiff (& ptracers):
1471      - re-work the code to check for valid advection scheme and for minimum
1472        size of overlap (now stored in local common bloc in gad_advscheme.F)
1473    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1474      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1475      - add an auxilliary variable "bet" and fix store directives and keys in
1476        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1477        less exact gradients in my tests); but there are still
1478        recomputation warning (although gradients are sort of OK), when
1479        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1480        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1481      - update verification experiments lab_sea.
1482      - change some comments in S/R seaice_calc_viscosities
1483    o model/src:
1484      - if staggerTimeStep=T, always apply exchange to velocity field in
1485        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1486        (independent of using multi-dim advection or not); no effect on FWD run
1487        but affects AD results (at machine truncation level): update output of
1488        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1489        and isomip (oad: 12.d).
1490    o pkg/generic_advdiff:
1491      - stop if doAB_onGtGs is set to FALSE but ignored
1492      - refine warning related to stability of tracer time-stepping
1493        regarding internal wave dynamics.
1494      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1495        on staggerTimeStep & implicitIntGravWave (will now get a warning
1496        if potentially unstable).
1497    o pkg/kl10:
1498      - add new pkg "kl10" for mixing due to internal wave breaking, from
1499        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1500        (contribution from Jody Klymak), tested in verification experiment
1501        verification/internal_wave/input.kl10/
1502    o isomip experiment:
1503      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1504        (input.htd) and update the output.
1505    o cd_code experiments:
1506      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1507        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1508        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1509        update the corresponding output.
1510    o pkg/seaice:
1511      - reduce the number of include files and store directives in
1512        S/R seaice_lsr_tridiagu/v
1513      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1514        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1515        get rid off one store directive (a TAF bug?)
1516      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1517        S/R seaice_lsr_tridiagv to change the loop range for consistency
1518      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1519      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1520        S/R seaice_lsr_tridiagu/v (requires update of
1521        offline_exf_seaice/input.dyn_jfnk)
1522    
1523    checkpoint65a (2014/07/27)
1524    o model/src:
1525      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1526        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1527        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1528        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1529    o model/src:
1530      - collect momentum forcing tendency into local 2-D array (passed as argument
1531        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1532        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1533        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1534      - collect T & S forcing tendency into local 2-D array (passed as argument to
1535        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1536        affects results at machine truncation level (e.g., ocean: if using
1537        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1538        correction due to vertical advection).
1539      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1540        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1541        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1542        obcs_ctrl (ad & fwd grd @ 12 & 7).
1543    o pkg/ptracers & diagnostics:
1544      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1545        title (to avoid some unexpected truncation); sort out ptracers diags units.
1546      - collect ptracer forcing tendency into local 2-D array (passed as argument
1547        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1548    
1549    checkpoint65 (2014/07/18)
1550    o pkg/fizhi:
1551      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1552        affects results at machine truncation level. Update output of experiments
1553        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1554    o pkg/seaice: more clean up
1555      - rename TAF common block tapes to be more consistent and remove
1556        unnecessary duplicates
1557      - add store directives to remove more recomputations, but use smaller
1558        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1559        The idea behind this flag is to reduce the memory footprint when the
1560        adjoint of the LSR is not required. As of now, defining the flag
1561        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1562        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1563        For experiment offline_exf_seaice, this means on a linux box with gfortran
1564        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1565        this experiment):
1566        > size mitgcmuv_ad
1567        text    data        bss     dec        hex
1568        5100659 1216  220458952  225560827  d71c8fb
1569        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1570        but only a moderate increase of 36% for global_ocean.cs32x15:
1571        text    data        bss     dec        hex
1572        6695027 1648 1014578664 1021275339 3cdf6ccb
1573        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1574      - note: there are still recomputations in global_ocean.cs32x15 and
1575        offline_exf_seaice and the gradient agreement changes (gets a
1576        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1577      - in general, the AD gradients still are wrong
1578    o OpenAD
1579      - clean up code_oad/ directories somewhat by moving files
1580        dontCompile, dontTransform, keepOriginal to OAD_support/
1581    o model/src:
1582      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1583        (not currently tested): add dissipation terms before NLFS rescaling of
1584        tendencies (previously done after).
1585    o pkg/diagnostics:
1586      - write stats-diags in ascii file with more digits (same as in monitor).
1587    o pkg/down_slope:
1588      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1589        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1590    o model/src:
1591      - new file "apply_forcing.F" containing all the code previously in
1592        external_forcing.F, but with new argument list: pass, as new argument,
1593        the current level tendency array to update (instead of a direct update
1594        of the common bloc array). Change the corresponding calls.
1595      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1596        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1597    o pkg/seaice/seaice_lsr, a little bit of clean up
1598      - rearrange some code blocks, so that now all calculations for
1599        setting up the right-hand-sides done within one single block
1600        (I find that easier to read and understand)
1601      - rearrange freedrift-code to reduce the number of ifdefs
1602      - adjust some indentations and comments
1603    
1604    checkpoint64z (2014/07/10)
1605    o model/src and several pkgs:
1606      - change argument list of all S/R called from external_forcing.F and
1607        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1608        to pass, as argument, the current level tendency array to update
1609        (instead of a direct update of the common bloc array).
1610      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1611      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1612    o pkg/seaice/seaice_lsr.F
1613      - always initialize local arrays in seaice_lsr_tridiagu/v
1614      - add more local tapes to seaice_lsr_tridiagu/v
1615      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1616        keep it in bi/bj loop; this seems to be essential
1617      - gradients are still wrong but only by 4-7 orders of magnitude
1618        instead of 15 orders of magnitude, lab_sea improves a little
1619  o pkg/seaice  o pkg/seaice
1620    - remove unnecessary u/vTmp from subroutine call of    - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1621      seaice_lsr_tridiagu/v      generates unnecessary code in seaice_lsr_ad
1622      - add more store directives in seaice_lsr to avoid unnecessary code
1623        in seaice_lsr_ad
1624      - exclude some residual computations in seaice_lsr when
1625        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1626        in seaice_lsr_ad
1627      - add more storing, a new tape (model/src/the_main_loop.F) and
1628        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1629        and klockey should be checked by a specialist)
1630      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1631        and update lab_sea after previous changes in pkg/seaice below
1632    o pkg/autodiff:
1633      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1634        viscFacInAd : run time parameters allowing for adjoint switches
1635        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1636    o pkg/ecco:
1637      - introduce cost_gencost_boxmean.F that computes a box mean
1638        temperature (for use in adjoint sensitivity studies).
1639    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1640    o pkg/mom_common/mom_calc_visc.F:
1641      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1642    o pkg/seaice/seaice_summary.F:
1643      - statement for SEAICEadjMODE now in autodiff_readparms.F
1644    o pkg/seaice:
1645    - remove some store directives and add new ones in an effort to get    - remove some store directives and add new ones in an effort to get
