4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/dic:
8      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
9        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
10        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
11      - move also update with values from ATM-OCN Coupler in the same new S/R
12        (previously done in ocn_apply_import.F).
13    o tools/adjoint_options:
14      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
15        has been changed on Jan 14, 2016.
16    o pkg/ggl90:
17      - add alternative discretisation of vertical shear (off by default), to
18        compute the mean (@ grid-cell center) of vertical shear compon instead of
19        vertical shear of mean flow (@ grid-cell center).
20      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
21        results on adjacent faces of cubed-sphere grids; this fix the restart.
22    o pkg/atm_compon_interf:
23      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
24        pass last value, stored directly before export to CPL ;
25        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
26      - remove atmSLPr from pickup files (no longer needed for restart)
27    
28    checkpoint65s (2016/01/13)
29    o eesupp & genmake2:
30       - first check for Function ETIME and, if it fails, then check for subroutine
31         ETIME and consistent output; use the appropriate version in timers.F
32    o model/src:
33      - to check restart test, add option to apply EXCH to U,V earlier, just before
34        integr_continuity; turned off by default.
35    o pkg/dic:
36      - remove CPP option USE_ATMOSCO2 (not needed)
37    o tools/tst_2+2:
38      - try to ignore difference between +0 and -0 in binary file, causing test
39        to fail for no good reason.
40    o eesupp & genmake2:
41      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
42        but also check (in genmake2) that test runs and returns meaningful results.
43    o coupler pkgs:
44      Finish implementation of optionally-exchanged variable switches (started on
45       Nov 12) with addition of few more exchanged fields, including 2-way exchange
46       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
47       advection in OCN component; this requires sequential coupling.
48      coupler (pkg/atm_ocn_coupler):
49      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
50        routines (useful for debug).
51      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
52         flux, DIC fields) if corresponding switch is ON.
53      - add option to export RunOff to OCN (to use for DIC river input)
54      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
55      components (pkg/atm_ & ocn_compon_interf):
56      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
57        optionally exchanged fields; add a check & stop in cpl_readparms.F.
58        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
59        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
60      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
61        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
62      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
63      - hold in common block coupler optionally-exchanged variable switch
64        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
65      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
66        this is intended to replace the OCN cplFldtave.* output files (not updated
67        to contain new additional exchanged fields).
68    o pkg/dic:
69      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
70    o pkg/thsice:
71      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
72        and writing of thsice pickup files.
73    o pkg/atm_compon_interf:
74      - move all field individual export-call out of cpl_export_import_data.F
75        into new S/R ATM_EXPORT_FIELDS
76    o pkg/atm_compon_interf:
77      - store state variables (for now, only thSIce fields) just before beeing
78        exported (in cpl_export_import_data.F, like on ocean side) instead of from
79        atm_store_my_data.F like all exported fluxes.
80      - new version of pickup_cpl: write field names into meta file and read meta
81        file to find field postion in pickup. Also only write/read fields meeded for
82        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
83    o pkg/dic:
84      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
85    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
86        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
87        value can be from domain [0,1] to average between the two methods
88    o pkg/atm_phys:
89      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
90        hold fixed in time).
91    
92    checkpoint65r (2015/12/21)
93    o pkg/seaice:
94        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
95        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
96    o pkg/seaice:
97      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
98        when SEAICEscaleSurfStress=.TRUE.,
99      - apply areaW and areaS in S/R seaice_calc_lhs
100    o pkg/atm_phys:
101      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
102        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
103        for individual contribution (convection, LSC cond, radiation)
104      - add Ruth Geen etal, GRL 2016, radiation optionis (see paper supp.
105        information); activated with: solar_exponent=0. and wv_exponent=-1.
106    o pkg/ggl90:
107      - within IDEMIX add upper limit for horizontal group velocity to
108        avoid instability problems in the explicit horizontal diffusion term for
109        long time steps or high resolution
110    o pkg/diagnostics:
111      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
112        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
113    o testreport:
114      - remove "-v" (verbose option) in default mpirun command.
115    o pkg/seaice/seaice_growth:
116      - catch potential division by zero in ITD code, does not change
117        verification results
118    o pkg/ecco:
119      - retire old codes to the Attic. The calls to retired functions are
120        left in a commented form in case they ever need to be re-activated.
121      - ecco_check.F: issue warning if any old CPP option is
122        defined that corresponds to retired codes -- then stop.
123    o pkg/atm_compon_interf:
124      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
125        coupler: use last time-step value instead of average over cplSendFrq_iter
126        time-step, similar to what is done for seaIceMass.
127        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
128    o eesupp & genmake2:
129      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
130        <= remove until a fix is found for some ifort version on ia32 machine.
131    o pkg/seaice/seaice_evp:
132      - refine residual computation
133    
134    checkpoint65q (2015/11/18)
135    o pkg/seaice/seaice_evp:
136      - fix residual computations so that they no longer affect the actual
137        simulation code
138      - fix seaice_readparams to be able to actually set new parameters
139        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
140    o model/src:
141      - fix wrong truncation (single prec) from "FLOAT" function in expressions
142        like: deltaT*FLOAT(myIter) when myIter is large:
143         a) replaced by DFLOAT (if not seen by TAF);
144         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
145    o pkg/aim_v23:
146      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
147        when pickupSuff is set ; do write rolling pickups + at the end of the run.
148    o pkg/atm_ocn_coupler + ocn_compon_interf:
149      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
150        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
151        add corresponding call in DO_OCEANIC_PHYS.
152    o coupler pkgs:
153      Start a new way to set-up optionally-exchanged variables (previously, only
154       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
155       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
156       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
157       compononent param default can be set accordingly).
158      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
159       but rather applies to a group a fields (going both ways like for DIC)
160       and corresponds to an option of coupling config.
161      coupler (pkg/atm_ocn_coupler):
162      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
163        and read namelist directly (without eessup S/R calls) instead of
164        in the very un-flexible old way, 1 param per line, in fixed order;
165      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
166        cleanly in CPL_CHECK_CPLCONFIG
167      - add new coupling-exchange selectors (some not yet active) including
168        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
169                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
170      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
171        component ; called directly from coupler.F, after comp. registrations;
172      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
173         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
174          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
175      components (pkg/atm_ & ocn_compon_interf):
176      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
177        CPP header file in all pkg source files.
178      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
179        ATM/OCN_CHECK_CPLCONFIG;
180      - add error-counter to track errors (e.g., in "data.cpl") and to stop
181        cleanly in ATM/OCN_CHECK_CPLCONFIG;
182      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
183        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
184        before PACKAGES_READPARMS;
185      verification/cpl_aim+ocn/:
186      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
187        "data.cpl" for coupler (in input_cpl).
188    o eesupp/inc:
189      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
190        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
191        to always cumulate tile local-sum in the same order (still uses
192        MPI_Allreduce like standard code).
193      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
194        that are now identical to standard version (in eesupp/inc).
195    o pkg/shelfice:
196      - add SHELFICETransCoeffTFile for initializing spatially varying
197        heat and salt transfer coefficients
198    o pkg/atm_compon_interf & ocn_compon_interf:
199      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
200        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
201      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
202    o pkg/atm_ocn_coupler:
203      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
204    o pkg/rbcs:
205      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
206        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
207      - add a short report (to STDOUT) about RBCS-mask settings.
208    
209    checkpoint65p (2015/10/23)
210    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
211        there is no adjoint test for EVP, we don't know what it does to the adjoint
212        solution, but at least there are no more recomputation warnings left
213    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
214        a chance of giving the same results as a fully converged VP (JFNK) solver
215    o tools/adjoint_options/adjoint_diva:
216      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
217    o pkg/streamice:
218      - spotted bug in streamice_driving_stress using dyG where should have been dxG
219    o pkg/exf:
220      - remove STOP statement that prevented to use wind or (wind-)stress
221        interpolation for constant-in-time forcing fields (wind/stress period = 0).
222    o pkg/seaice:
223      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
224        5 additionals 2D fields and 6 new store directives
225      - change logic in seaice_readparms.F: EVP code can now be turned on in
226        various ways, setting SEAICE_deltaTev is no longer required,
227        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
228        or SEAICEaEVPcoeff
229    o pkg/shelfice/shelfice_thermodynamics.F
230      - redefining uLoc/vLoc to u/v, instead of 2u/v
231    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
232      - this is an intermediate state of a truely converging EVP that has
233        the potential of outperforming implicit VP methods, I do not recommend
234        using it yet.
235      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
236        and all parameters are hardwired
237      - for convergence it still requires very smooth regularisations, that means,
238        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
239        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
240        specific averaging appears to be required, still subject to tuning
241      - still needs cleaning and I need to turn parameter into runtime parameters
242      - add code to compute and print residuals of iteration, compile with
243        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
244    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
245      that entered with r1.54 on Sep04, 2015, -> update results
246    
247    checkpoint65o (2015/09/14)
248    o pkg/mom_vecinv & mom_common:
249      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
250        called from there.
251      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
252        allows to use Vector-Invariant form in deep atmos and anelastic formulation
253    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
254      and Koenig-Beatty+Holland (2012)
255      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
256      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
257      - requires an extra input argument for S/R seaice_calc_viscosities
258      - tensileStrength's depth dependence is different from Itkin et al. (2015)
259        (to be changed and played with, for now exponential)
260    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
261      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
262        by AREA according to Connelly et al. (2004), JPO.
263      - For EVP and the LSR solver, the implicit part of the drag term is
264        the only non-zero term in the denominator when there is no ice (which
265        prevented running the model with zero ice-ocean drag). If
266        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
267        (or zero main diagonals BU/BV) which need to be caught. A practical
268        consequence is that for open water, the momentum equation reduce
269        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
270        they happen to be zero, often leading to a non-zero solution over
271        open water.
272    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
273        efficient EVP method.
274      - introduce area-weighted averages for e12 (analogously to
275        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
276        remain, but also changing the order of terms in the previous average
277        changed the results as much) -> update experiment
278      - add SEAICE_DELTA_SMOOTHREG code
279      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
280        TEM-code
281      - adjust loop bounds so that only required fields are computed
282      - add new averaging code for zetaZ/deltaZ (again similar to
283        seaice_calc_viscosities.F), inactive by default for now (will change
284        results again), but will replace old code eventually
285    o eesupp/src:
286      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
287        to always cumulate tile local-sum in the same order
288        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
289        Still uses MPI_Allreduce (like standard code) but on array of tiles
290        and should be faster than GLOBAL_SUM_SEND_RECV code.
291      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
292        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
293      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
294         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
295         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
296         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
297         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
298    
299    checkpoint65n (2015/07/29)
300    o pkg/thsice:
301      - add a warning when used with pkg/aim but without updating SST
302        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
303    o pkg/offline:
304      - change where Offline-Fields are loaded, from load_fields_driver.F to
305        directly within FORWARD_STEP, just after updating iter number and time;
306      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
307        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
308       These changes allow:
309        a) to recover exactly on-line results using deltaToffline=deltaTClock,
310        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
311        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
312        time-step, both with GM & KPP files and with recomputing these fields;
313        b) no needs to switch on staggerTimeStep anymore;
314        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
315      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
316    o pkg/offline:
317      - change (rarely used) offset-iteration parameter to an offset time (in s):
318        can easily recover previous offset-iter effect by setting offset-time
319        (offlineTimeOffset) to offset-iter x deltaToffline;
320      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
321        in KPP as part of surface buoyancy forcing) in offline run.
322      - fix ptracers KPP non-local term in the case where KPP is re-computed.
323    o OpenAD
324      - Adding preliminary ggl90 test to OpenAD verification.
325        Config. with ggl90 currently diverges after 64 time steps
326        so will need more work to become more stable
327      - Adding preliminary kpp test to OpenAD verification.
328        required small tweakes in kpp_routines.F
329      - Merge and update from Krishna Narayanan's contrib area:
330        * Add one variable for preliminary OpenAD DIVA
331        * Add replacement time-stepping for OpenAD DIVA
332        * genmake2 flag -diva (but only for OpenAD; preliminary)
333        * required modifs for OAD_support
334        successful preliminary test for tutorial_global_oce_biogeo/
335    o pkg/seaice:
336      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
337      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
338        delta with a smooth function in s/r seaice_calc_viscosity
339        (no effect on EVP)
340      - rename local suffix "sqr" into "sq" for more consistent variable names
341    o pkg/seaice:
342        add new parameter SEAICE_deltaMin that is used ***only***
343        for regularizing Delta (and nothing else, like the parameter
344        which is also used for all sorts of things SEAICE_EPS).
345        Defaults to SEAICE_EPS for backward compatibility only.
346    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
347        the wrong key by inialising it before use -> fixes a recomputation
348        problem but does not fix the gradient
349    o pkg/layers:
350      - move resetting of flux arrays to outside the iLa loop
351        (this caused layers_diapycnal to not work with more than one layer coord.)
352      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
353    o pkg/layers:
354      - remove from common block 3D layers fields (used to diagnose transport
355        in tracer coords) and declare them as local arrays in layers_calc.F
356    o pkg/seaice:
357      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
358        in lab_sea forward experiment (changes results -> updated)
359      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
360    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
361       computations; for SEAICE_VECTORIZE_LSR
362      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
363        sweep to the outside,
364      - remove store directives and add "CADJ loop sequential" directives
365        in analogy to model/src/solve_tridiagonal.F
366      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
367        boundaries to yield more readable code. This has also the charming side
368        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
369        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
370        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
371        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
372        an additional option)
373       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
374       but the adjoint gradients (which are affected by this change) still explode.
375    o coupler (atm & ocn _compon_interf):
376      - avoid using Exch2 IO mapping if not suitable.
377    
378    checkpoint65m (2015/06/15)
379    o pkg/layers:
380      - clean-up old parameters setting (from Sep 2012):
381        + remove old parameters setting from common block (declared locally);
382        + stop if any old parameter is mixed with new parameters;
383        + check for valid or consistent parameter setting (e.g., layers_name)
384      - check that layers_bounds for Pot.Density are in the right range;
385        this is supposed to catch un-updated setting after recently shifting
386        potential density field "prho" by -1000 (now in "sigma" scale).
387    o pkg/layers:
388      - Added missing call to layers_fill for keeping track of tottend in
389        pkg/diagnostics/diagnostics_fill_state.F
390    o pkg/layers:
391      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
392        of diapycnal fluxes
393    o pkg/layers:
394      - reverted changes to interpolation to previous treatment; there
395        was never actually a problem
396    o pkg/layers:
397      - fix interpolation of layers tracers in the presence of partial cells
398      - add lots of new functionality to compute water mass transformation
399        (enabled by CPP flag LAYERS_THERMODYNAMICS)
400      - add new calls from main code (diags_oceanic_surf_flux.F,
401        thermodynamics.F, impldiff.F) and gad to save the necessary fields
402        for layers_thermodynamics calculations
403    o pkg/ptracers:
404      - add capability of stepping a passive tracer forward without advection
405        by setting PTRACERS_advScheme to 0.
406    o pkg/diagnostics:
407      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
408    o pkg/layers:
409      - shift potential density field "prho" by -1000 for density layer averaging so
410        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
411        Note that density bin boundaries (layers_bounds in data.layers) have
412        to be set accordingly (i.e., shifted, in sigma scale).
413    o pkg/layers:
414      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
415      - fix calculation of layer non-weighted velocity and layer probability
416      - add diagnostics for pot.density used for layer averaging
417    o pkg/seaice:
418      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
419        positiveness, modify a few comments and improve variable names,
420      - the changed computation of deltaC affects most seaice-related
421        experiments at the truncation level.
422        seaice_itd.thermo is affected by far the most, with
423        only 7 digits of agreement remaining; update experiments.
424    
425    checkpoint65l (2015/05/04)
426    o pkg/shelfice:
427      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
428        factor drKp1 to zero where it is negative (ie. do not use
429        SHELFICEBoundaryLayer if hFacC>1)
430      - the same for factor drLoc in shelfice_forcing.F
431    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
432        with modules in ptracers, when using testreport option "-small_f"
433    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
434      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
435    o verification/testreport
436      - add new option -small_f
437        with this option testreport first makes the target small_f (*.f files)
438        before running make (all). This is useful for explicit inlining when
439        all sources need to be full available.
440    o pkg/exf/exf_interp.F:
441        remove previous changes related to reverse (decreasing) input grids latitude
442    
443    checkpoint65k (2015/04/01)
444    o pkg/ecco:
445        fix missing cosphi initialization; use eccoiter in place of optimcycle;
446        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
447        instead of active read/write
448    o pkg/ctrl:
449        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
450        instead of active read/write.
451    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
452        return if .NOT.useAUTODIFF
453    o pkg/seaice: add CPP brackets (cost function related).
454    o model/src:
455        add useAUTODIFF run time switch.
456    o pkg/exf/exf_interp.F:
457        add code to allow input grids with latitude starting in the north (i.e. when
458        j=1 corresponds to northern edge of field); modify global_with_exf to test
459        this feature.
460    o verification/testreport:
461      - replace "grep -A3" with POSIX conformal sed command, because there are
462        implementations of grep that cannot do contextual searches
463      - replace "cat -n" by "nl" (two occurrences), because not all implementations
464        of "cat" have the option "-n"
465    o model/src:
466        add new file gsw_teos10.F that contains 3 functions, more or less a copy
467        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
468        convert from conservative to potential temperature. For now they are not
469        called anywhere.
470    o pkg/ggl90: make "useIDEMIX" useful
471      - re-organize code in s/r ggl90_calc a little to move computations that
472        are different for idemix into separate loops (changes verification
473        experiment idemix at truncation level, 12 digits remain -> updated)
474      - requires 2 new 2D fields KappaM, verticalShear
475      - make hFacI and recip_hFacI local 3D variables that are passed to
476        s/r ggl90_idemix
477      - fix and improve some comments
478    
479    checkpoint65j (2015/02/25)
480    o pkg/openad
481      - synchronize seawater.F with version in model/src: replace routine
482        body of sw_temp by calling sw_ptmp and fix/add a few comments.
483    o pkg/mnc:
484      - change default value of pickup_read/write_mnc params to FALSE
485        (since few features are missing in reading MNC pickup files).
486    o model/src:
487      - change default (background) vertical diffusivity for salt to be the
488        temperature (background) vertical diffusivity.
489      - change background vertical diffusivity in vertical mixing pkgs ggl90,
490        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
491        This makes ptracers default diffusivity (that uses salt diffKr) more
492        consistent with vertical mixing schemes.
493    o verification/testreport:
494      - fix typo in "-pcls" option ;
495      - put temp files in /tmp (instead of in local dir)
496      - add option "-ncad" to use genmake2 new option "-nocat4ad"
497      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
498    o pkg/ggl90 (idemix code):
499      - apply few fixes ; add some missing "_d 0" ; update output of exp.
500        global_ocean.90x40x15.idemix
501    o OpenAD
502      - enable active file I/O and begin removal of work-around code
503        for OpenAD for handling control variables (memory vs. active files)
504      - new CPP options file OPENAD_OPTIONS.h
505      - revert to genarr2d gradient check for hs94.1x64x5
506      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
507      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
508    o tools/genmake2:
509      - add option for an alternative Makefile (from Martin) where multiple
510        source files are sent to TAF (instead of all in one file).
511    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
512      - code provided by Carsten Eden as an extension of ggl90
513      - so far the code is turned on within ggl90 by setting a CPP-flag at
514        compile time; a runtime flag implementation is not yet complete
515      - tested in new verification experiment global_ocean.90x40x15.idemix
516    o verification:
517      - reduce length of the AD test run by half for experiments
518        global_ocean.cs32x15 (std + thsice) and isomip
519      - enable active file I/O for OpenAD, adjust verifications accordingly
520      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
521    o verification/testreport:
522      - fix two non-POSIX sed statements so that there are no error messages
523        on Mac OS X
524      - replace hostname -s with hostname | sed 's/\..*$//'
525    o model/src/seawater.F:
526      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
527        (following the matlab code), which would have avoided the bug caught
528        by Matt (see below) in the first place
529    o pkg/shelfice:
530      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
531        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
532      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
533        ice-shelf case (i.e., within surface level).
534      - add config summary in shelfice_check.F
535      - remove global variable recip_SHELFICElatentHeat and replace by a local
536        variable recip_latentHeat
537      - introduce diagnostics for friction velocity uStar (in case of
538        SHELFICEuseGammaFrict)
539      - change verification experiment isomip.htd:
540        + start from pickup (as input_ad at nIter0=8640)
541        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
542        + test SHELFICEuseGammaFrict = .TRUE.
543        + test SHELFICEadvDiffHeatFlux = .TRUE.
544    o model/src:
545      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
546        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
547        update output of experiments global_with_exf.yearly and isomip (all 6).
548    o pkg/shelfice:
549      - change setting of kTopC to also be zero where there is no ice-shelf.
550      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
551        ice-shelf is.
552      - first attempt to get RealFreshWaterFlux effects: for now, only without
553        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
554    o pkg/seaice: add the option to prescribe a fixed thickness PDF
555      for thermodynamic calculations
556      - because of divisions of the type 7/7 not exactly equal to 1, this change
557        affects results of some verification experiments by up to 4 digits:
558        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
559        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
560        adjoint: lab_sea, lab_sea.noseaicedyn
561        -> updated
562    
563    checkpoint65i (2015/01/23)
564    o model/src:
565      - change units of frictionHeating field from W to W/m^2
566      - fix bug in frictional heating from stratospheric drag in
567        S/R ATM_PHYS_TENDENCY_APPLY_V
568      - with synchronous time-stepping: move resetting to zero of frictionHeating
569        field from load_fields_driver.F to thermodynamics.F ;
570      - add diagnostics for frictional heating.
571    o model/src & gmredi K3D:
572      - add frictionHeating field to pickup-files (for synchronous time-stepping)
573      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
574      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
575        and name in pickup file).
576      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
577    o model/src:
578      - move (from ini_forcing.F) initialisation of all arrays in header file
579        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
580        (since Nov 2012) with option selectAddFluid=1.
581    o pkg/shelfice:
582      - change units (+ document) of newly added field "shelfIceMassDynTendency"
583      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
584    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
585    o pkg/seaice: two new runtime parameters:
586      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
587        long overdue
588      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
589        parameterization of tensil stress for fast ice (does not do anything yet)
590    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
591        for LSR: move checking overlaps out of JFNK-if-block
592    o pkg/atm_phys:
593      - move copy of grid and dynamical fields out of atm_phys_driver.F into
594        new S/R ATM_PHYS_DYN2PHYS.
595      - fix level height for Linear Free-Surf case (to be consistent with
596        fixed-in-time pressure levels).
597    o pkg/mom_common (bottomdrag):
598      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
599        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
600        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
601    o pkg/shelfice (u/v_drag):
602      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
603      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
604        (now similar to shelfice_u_drag.F)
605      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
606        from mom_vecinv.F (similar to mom_fluxform calls).
607    o pkg/mom_common (bottomdrag):
608      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
609      - add options for alternative discretisation of velocity norm in quadratic
610        bottom drag: averaging of grid-cell-center KE to U.point and V.point
611        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
612        improves when averaging only the other component (e.g. vVel for U bottom
613        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
614      - add options (bottomVisc_pCell) to account for partial-cell in bottom
615        friction (no-slip BC) thus getting the true distance from the bottom;
616        off by default since this also reduces model stability (explicit bottom
617        friction). Changes produce different machine truncation with linear-drag
618        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
619        front_relax (bvp & mxl, 10 & 11 digits).
620    o model/src & mom pkgs:
621      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
622        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
623      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
624        just copy level Nr value to level Nr+1.
625    o doc:
626      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
627    o pkg/streamice:
628      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
629        SHELFICE.h: move array shelficemass to init_varia, initialise
630        from array shelficemassinit, which is set in init_fixed and
631        has option to be set from file; introduce array
632        shelficeMassDynTend array, set thru file in init_fixed
633      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
634        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
635        pkg/streamice
636      - shelfice_thermodynamics.F: call shelfice_step_icemass if
637        SHELFICEMassStepping = .true.
638      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
639    
640    checkpoint65h (2014/12/17)
641    o verification/global_ocean.90x40x15, global_ocean_ebm:
642      - update to generic controls.
643    o pkg/ctrl:
644      - ctrl_map_ini_genarr.F: test for igen>0
645      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
646      - move gentim2d part of ctrl_map_ini_genarr.F to
647        new separate routine : ctrl_map_ini_gentim2d.F
648      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
649        add time variable weights and cyclic controls (time mean,
650        seasonal cycle, etc) capabilities to gentim2d
651    o pkg/ecco:
652      - move reading of error, conversion to weights from
653        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
654    o global_oce_llc90, cs32:
655      - activte sbo.
656      - CTRL_SIZE.h : add maxCtrlProc.
657      - activate the new genctrl capabilities.
658      - update following reorganization of global_oce_input_fields.tar.gz  
659    o pkg/ctrl/ctrl_ad_diff.list:
660      - add missing ctrl_init_rec.f
661    o tools/OAD_support/keepOriginal:
662      - add ctrl_init_rec.F
663    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
664      - avoid recomputations of xx_gentim2d_dummy.
665    o momentum diagnostics:
666      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
667        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
668    o pkg/seaice/seaice_lsr.F:
669      - fix computation of BU/BV, make sure they are non-zero, only necessary
670        for cubed sphere exchanges and SEAICE_OLx/y>0.
671        This makes calling s/r fill_cs_corner_rl obsolete (removed).
672    o verification/global_ocean.cs32x15/input.seaice
673      - add test for strong implicit coupling and restricted addtive Schwarz
674        methods for LSR
675      - update results/output.seaice.txt
676    o verification/tutorial_global_oce_biogeo:
677      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
678        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
679        update output_adm,_oadm,_tlm.txt
680    o pkg/dic:
681      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
682      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
683        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
684    o verification/tutorial_global_oce_biogeo:
685      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
686        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
687        update output_adm,_oadm,_tlm.txt
688    o eesupp/src:
689      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
690        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
691    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
692      LSR (following Hutchings et al. 2004)
693      - introduce zetaZ as a global variable (requires adjustments in
694        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
695        in seaice_calc_viscosities.F
696      - new flag SEAICEuseStrImpCpl (default off)
697      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
698        momentum equations
699      - JFNK-solver (preconditioner) adjusted to allow using this method
700        (where it does not have any positive effect)
701    o pkg/seaice
702      - add overlap for restrictive additive Schwartz method also to LSR, but
703        turn it off by default (because it only seems to work for non-cubed
704        sphere/llc topologies)
705    o pkg/autodiff
706      - add extra exchanges in addummy_in_steppging also for mnc output
707    o pkg/seaice:
708      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
709        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
710    o pkg/obcs:
711      - add option to specify domain-connected piece Id along OB though files
712        (for now, only used to diagnose PhiVel; default =1 -> global correction)
713      - modify obcs_diag_balance.F to process each connected-part separately;
714        exclude OB where Id = 0 but keep the full divergence there (-> constant
715        Psi along this portion of OB and all inflow derived from grad(Phi))
716      - add example of OB-conect files in verification/so_box_biogeo/input.
717    o pkg/diagnostics:
718      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
719      a) use non zero matrix element across OB and solve for Phi 1 grid point
720         outside OB (i.e, where tracer OBCS are applied).
721      b) global imbalance of inFlow/outFlow across OB: instead of modifying
722         velocity across OB, spread it uniformly along the OB in the RHS.
723    
724    checkpoint65g (2014/11/19)
725    o pkg/diagnostcis:
726      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
727    o pkg/my82,pp81,kl10:
728      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
729        field diffKr as background diffusivity to set minimum diffusivity value.
730    o pkg/seaice:
731      - add new parameter SEAICEuseEVPrev (for revisited EVP by
732        Bouillon et al 2013)
733      - add SEAICE_evpAlpha/Beta to namelist
734      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
735        involve trivial re-ordering of divisions/multiplications that should not
736        have any effects, but ... they do change the results of lab_sea.hb87 so
737        that only 2 digits of agreement remain, in line with the general
738        instability/fragility of the evp-code. For now, I do not care and just
739        update the verification experiment
740    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
741      - remove xx_genarr2d_numsmooth etc
742      - use xx_genarr2d_preproc etc instead
743      - carry out smooth_correl2D at initialization stage rather than during
744        time stepping.
745      - get smoothOpNb from xx_gentim2d_preproc
746    o global_oce_cs32 :
747      - add test of generic ecco capabilities.
748    o pkg/exf/exf_getsurfacefluxes.F :
749      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
750    o pkg/ctrl,ecco :
751      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
752        is defined.
753    o pkg/seaice: add diagnostics for Delta (deformation parameter)
754    o model/src:
755      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
756        diffusivity (background) is specified but ignored.
757    o verification:
758      - in testreport, convert hostname to lower case for default output dir name
759    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
760    o pkg/dic: add modifications from Hajoon:
761      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
762      - light attenuation: add self-shading effect by climatological Chlorophyll
763        (read from file).
764    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
765        compiles when SEAICE_ALLOW_DYNAMICS is undefined
766    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
767        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
768        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
769        approach where CPP_OPTIONS.h includes an omnipotent
770        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
771    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
772        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
773    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
774        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
775        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
776    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
777      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
778      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
779      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
780      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
781    o pkg/ctrl,ecco,exf :
782      - remove variables associated with NON-generic costs,
783        unless ECCO_CTRL_DEPRECATED is defined.
784      - remove NON-generic NON-obcs controls,
785        unless ECCO_CTRL_DEPRECATED is defined.
786    o pkg/ctrl : added ctrl_local_params.h
787    o pkg/ecco : added ecco_local_params.h
788    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
789        experiments, which will progressively be removed once the
790        experiments are revised to use only generic controls/costs.
791    
792    checkpoint65f (2014/10/13)
793    o pkg/ctrl, ecco, seaice : minor changes in headers

797    o pkg/ecco: increase modularity and improve logic
798      - ecco_toolbox.F (new) : basic operations that are often used,

800        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
801      - cost_gencal.F (new) : determine filnames and records.
802      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
803      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
804        and exploit the above functions leading to more compact code.
805      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
806      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
807        using_ers, using_gfo, using_mdt is now only defined within gencost)
808    o pkg/ecco: extend generic cost capabilities
809      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
810        capabilities via gencost_preproc (+ _c,_i,_r related params),
811        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
812        gencost_outputlevel arguments to cost_generic
813      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
814        and active_read, making room for gencost_preproc to take effect.
815        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
816      - pkg/ecco/cost_generic.F :
817        compute and store misfit maks*(model-data) in localdif that is
818        then used in cost and for output, output misfit if outlev.GT.0
819      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
820        rather gencost_barfile for deciding whether to write barfile
821      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
822      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
823        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
824      - pkg/ecco/ecco_summary.F : report gencost variables
825      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
826    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
827    o pkg/ecco: internal re-organization
828      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
829        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
830        mv relevant variables definition from ecco_cost.h to ecco.h,
831        make sure gencost routines only include ecco.h)
832      - throughout : add missing CCP switches, rm unused variables,
833        and rm un-necessary CPP switches
834      - throughout gencost routines : replace modelstartdate with
835        gencost_startdate when needed
836      - cost_bp_read.F : use arguments, instead of common blocs
837        so that it can be used also by (new) cost_gencost_bpv4.F
838      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
839      - ecco_phys.F : compute etanFull
840      - ecco_readparms.F : rename using_topex as using_tpj, add
841        bpv4-grace to gencost list, initialize added parameters
842      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
843    
844    checkpoint65e (2014/09/28)
845    o pkg/obcs:
846      - replaced the just-added CPP options with run-time variables
847        (see pkg/obcs/OBCS_PARAMS.h for details)
848    o pkg/obcs:
849      - add additional CPP options for sponge boundary layers
850        (see pkg/obcs/OBCS_OPTIONS.h for details)
851    o pkg/atm_phys:
852      - implement simple (obliquity only, assuming circular planet orbit)
853        seasonal cycle for incoming insolation ; used when run-time parameter
854        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
855    o pkg/exf, pkg/ecco, pkg/ctrl:
856      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
857      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
858      - implement gentim2d for xx_tauu, xx_tauv
859    o pkg/ctrl, pkg/ecco :
860      - fix and complement the generic controls implementation
861    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
862        pkg/shelfice/shelfice_thermodynamics.F,
863        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
864        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
865      - add weight in CTRL_GET_GEN calls
866    o pkg/ctrl :
867      - ctrl_get_gen.F : add weight as input parameter, and apply
868        it directly rather than using smooth_correl2Dw (to be retired).
869      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
870    o pkg/ctrl :
871      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
872        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
873      - re-activate ctrl_summary (call in ctrl_init.F)

881    
882    checkpoint65d (2014/09/15)
883    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
884      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
885        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
886    o pkg/ctrl/ctrl_map_ini_genarr.F :
887      - remove compilation failure
888      - replace hard coded example
889      - use ctrl_map_ini_gen2D, 3D
890    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
891      - on/off switch based upon xx_genarr2d_weight,3d
892    o src/packages_init_variables.F :
893      - regroup pkg/estimation calls
894      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
895        (moved to ctrl_init_variables)
896    o cost/cost_init_varia.F :
897      - remove ecco_cost_init_varia
898        (moved to ecco_init_varia)
899    o ctrl/ctrl_init_variables.F :
900      - add CTRL_MAP_INI, CTRL_MAP_INI_ECCO
901      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
902    o ctrl/ctrl_map_ini.F :
903      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
904        (moved to ctrl_init_variables)
905    o ctrl/ctrl_map_ini_ecco.F :
906      - remove ECCO_PHYS (mv to ecco_init_varia)
907      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
908    o ecco/ecco_ad_diff.list :
909      - add ecco_init_varia.f
910    o ecco/ecco_init_varia.F
911      - new routine
912    o pkg/streamice:
913      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
914        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
915      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
916    o pkg/generic_advdiff:
917      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
918    o pkg/exf:
919      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
920         xxg_precip capability
921      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
922    o pkg/ctrl:
923      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
924    o model/src/load_fields_driver.F :
925      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
926        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
927    o OpenAD verification experiments:
928      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
929        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
930        for now, only in pkgs used in OpenAD verification experiments.
931      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
932        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
933        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
934        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
935    o OpenAD verification tests:
936      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
937      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
938        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
939      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
940        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
941    o model/src & generic_advdiff:
942      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
943        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
944        dynamics requires valid tracer forcing only over tile interior but, for
945        some diagnostics, may need to extend it over 1 point in tile halo region.
946      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
947        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
948        setting in temp/salt/ptracer_integrate.F
949    o pkg/dic:
950      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
951        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
952        in gchem_forcing_sep.F
953    o pkg/autodiff & obcs:
954      - add storage of current OB values for U & V (was already done for T & S).
955    
956    checkpoint65c (2014/08/30)
957    o pkg/dic:
958      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
959        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
960        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
961    o verification:
962      - new experiment testing OBCS and DIC pkgs, using params & output from
963        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
964        passage: take OBCS from the last year of a 2 yrs simulation and initial
965        conditions from t=1.yr while keeping the same forcing.
966    o model/src:
967      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
968        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
969    o pkg/diagnostics (Stats-Diags):
970      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
971        a) refine region where stats are computed, excluding where arrhFac=0 ;
972        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
973        c) extend regional stats over the region edges (for U or V pt location).
974    o pkg/gchem:
975      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
976        pkg/dic is currently changing/updating ptracers values beyond the OB).
977    o verification (hs94):
978      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
979        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
980        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
981        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
982    o pkg/ptracers:
983      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
984        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
985      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
986        with AB-2 code (so that it get tested).
987    o model/src:
988      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
989        with AB-2 code (previously only available with AB-3 code).
990        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
991        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
992        there, by calling CYCLE_AB_TRACER).
993    o pkg/generic_advdiff:
994      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
995        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
996        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
997        S/R temp/salt/ptracers_integrate.F
998    o model/src & pkg/ptracers:
999      - remove common block variables gT,gS (in DYNVARS.h), except when
1000         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1001      - remove common block variable gPtr.
1002    o model/src & pkgs:
1003      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1004         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1005         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1006         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1007      + change accordingly all calling S/R.
1008      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1009        in S/R temp/salt/ptracers_integrate.F
1010    o pkg/seaice:
1011      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1012        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1013      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1014        in seaice_lsr
1015      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1016        in s/r seaice_lsr_calc_coeffs
1017    o pkg/mdsio:
1018      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1019        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1020        too long (e.g., > MAX_LEN_FNAM/2 )
1021    
1022    checkpoint65b (2014/08/12)
1023    o pkg/matrix:
1024      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1025    o model/src:
1026      - fix initialisation of geothermalFile; compile geothermal-flux code in
1027        natl_box verification experiment.
1028    o model/src & pkg/down_slope:
1029      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1030      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1031        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1032        results at machine truncation level: update output of experiments
1033        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1034    o pkg/diagnostics (Stats-Diags):
1035      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1036        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1037        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1038        times (but Min,Max and StD are still wrong).
1039    o model/src:
1040      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1041        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1042    o model/src:
1043      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1044        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1045        arrays are already updated while adjustments (filters, conv.adjustment) are
1046        still applied later, in S/R TRACERS_CORRECTION_STEP.
1047    o model/src:
1048      - store in common bloc array "rhoInSitu" the virtual potential temperature
1049        anomaly that is used to compute geopotential: this make the atmos code
1050        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1051    o pkg/seaice/seaice_lsr.F
1052      - rename integer variable ilcall to ipass (that's what it is called
1053        in the residual diagnostics
1054      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1055        default) for improved non-linear convergence of the first few steps
1056      - adjust a few comments and add new ones to explain some of the store
1057        directives
1058    o pkg/generic_advdiff (& ptracers):
1059      - re-work the code to check for valid advection scheme and for minimum
1060        size of overlap (now stored in local common bloc in gad_advscheme.F)
1061    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1062      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1063      - add an auxilliary variable "bet" and fix store directives and keys in
1064        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1065        less exact gradients in my tests); but there are still
1066        recomputation warning (although gradients are sort of OK), when
1067        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1068        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1069      - update verification experiments lab_sea.
1070      - change some comments in S/R seaice_calc_viscosities
1071    o model/src:
1072      - if staggerTimeStep=T, always apply exchange to velocity field in
1073        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1074        (independent of using multi-dim advection or not); no effect on FWD run
1075        but affects AD results (at machine truncation level): update output of
1076        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1077        and isomip (oad: 12.d).
1078    o pkg/generic_advdiff:
1079      - stop if doAB_onGtGs is set to FALSE but ignored
1080      - refine warning related to stability of tracer time-stepping
1081        regarding internal wave dynamics.
1082      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1083        on staggerTimeStep & implicitIntGravWave (will now get a warning
1084        if potentially unstable).
1085    o pkg/kl10:
1086      - add new pkg "kl10" for mixing due to internal wave breaking, from
1087        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1088        (contribution from Jody Klymak), tested in verification experiment
1089        verification/internal_wave/input.kl10/
1090    o isomip experiment:
1091      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1092        (input.htd) and update the output.
1093    o cd_code experiments:
1094      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1095        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1096        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1097        update the corresponding output.
1098    o pkg/seaice:
1099      - reduce the number of include files and store directives in
1100        S/R seaice_lsr_tridiagu/v
1101      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1102        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1103        get rid off one store directive (a TAF bug?)
1104      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1105        S/R seaice_lsr_tridiagv to change the loop range for consistency
1106      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1107      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1108        S/R seaice_lsr_tridiagu/v (requires update of
1109        offline_exf_seaice/input.dyn_jfnk)
1110    
1111    checkpoint65a (2014/07/27)
1112    o model/src:
1113      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1114        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1115        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1116        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1117    o model/src:
1118      - collect momentum forcing tendency into local 2-D array (passed as argument
1119        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1120        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1121        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1122      - collect T & S forcing tendency into local 2-D array (passed as argument to
1123        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1124        affects results at machine truncation level (e.g., ocean: if using
1125        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1126        correction due to vertical advection).
1127      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1128        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1129        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1130        obcs_ctrl (ad & fwd grd @ 12 & 7).
1131    o pkg/ptracers & diagnostics:
1132      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1133        title (to avoid some unexpected truncation); sort out ptracers diags units.
1134      - collect ptracer forcing tendency into local 2-D array (passed as argument
1135        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1136    
1137    checkpoint65 (2014/07/18)
1138    o pkg/fizhi:
1139      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1140        affects results at machine truncation level. Update output of experiments
1141        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1142    o pkg/seaice: more clean up
1143      - rename TAF common block tapes to be more consistent and remove
1144        unnecessary duplicates
1145      - add store directives to remove more recomputations, but use smaller
1146        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1147        The idea behind this flag is to reduce the memory footprint when the
1148        adjoint of the LSR is not required. As of now, defining the flag
1149        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1150        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1151        For experiment offline_exf_seaice, this means on a linux box with gfortran
1152        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1153        this experiment):
1154        > size mitgcmuv_ad
1155        text    data        bss     dec        hex
1156        5100659 1216  220458952  225560827  d71c8fb
1157        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1158        but only a moderate increase of 36% for global_ocean.cs32x15:
1159        text    data        bss     dec        hex
1160        6695027 1648 1014578664 1021275339 3cdf6ccb
1161        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1162      - note: there are still recomputations in global_ocean.cs32x15 and
1163        offline_exf_seaice and the gradient agreement changes (gets a
1164        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1165      - in general, the AD gradients still are wrong
1166    o OpenAD
1167      - clean up code_oad/ directories somewhat by moving files
1168        dontCompile, dontTransform, keepOriginal to OAD_support/
1169    o model/src:
1170      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1171        (not currently tested): add dissipation terms before NLFS rescaling of
1172        tendencies (previously done after).
1173    o pkg/diagnostics:
1174      - write stats-diags in ascii file with more digits (same as in monitor).
1175    o pkg/down_slope:
1176      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1177        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1178    o model/src:
1179      - new file "apply_forcing.F" containing all the code previously in
1180        external_forcing.F, but with new argument list: pass, as new argument,
1181        the current level tendency array to update (instead of a direct update
1182        of the common bloc array). Change the corresponding calls.
1183      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1184        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1185    o pkg/seaice/seaice_lsr, a little bit of clean up
1186      - rearrange some code blocks, so that now all calculations for
1187        setting up the right-hand-sides done within one single block
1188        (I find that easier to read and understand)
1189      - rearrange freedrift-code to reduce the number of ifdefs
1190      - adjust some indentations and comments
1191    
1192    checkpoint64z (2014/07/10)
1193    o model/src and several pkgs:
1194      - change argument list of all S/R called from external_forcing.F and
1195        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1196        to pass, as argument, the current level tendency array to update
1197        (instead of a direct update of the common bloc array).
1198      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1199      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1200    o pkg/seaice/seaice_lsr.F
1201      - always initialize local arrays in seaice_lsr_tridiagu/v
1202      - add more local tapes to seaice_lsr_tridiagu/v
1203      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1204        keep it in bi/bj loop; this seems to be essential
1205      - gradients are still wrong but only by 4-7 orders of magnitude
1206        instead of 15 orders of magnitude, lab_sea improves a little
1207    o pkg/seaice
1208      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1209        generates unnecessary code in seaice_lsr_ad
1210      - add more store directives in seaice_lsr to avoid unnecessary code
1211        in seaice_lsr_ad
1212      - exclude some residual computations in seaice_lsr when
1213        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1214        in seaice_lsr_ad
1215      - add more storing, a new tape (model/src/the_main_loop.F) and
1216        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1217        and klockey should be checked by a specialist)
1218      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1219        and update lab_sea after previous changes in pkg/seaice below
1220    o pkg/autodiff:
1221      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1222        viscFacInAd : run time parameters allowing for adjoint switches
1223        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1224    o pkg/ecco:
1225      - introduce cost_gencost_boxmean.F that computes a box mean
1226        temperature (for use in adjoint sensitivity studies).
1227    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1228    o pkg/mom_common/mom_calc_visc.F:
1229      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1230    o pkg/seaice/seaice_summary.F:
1231      - statement for SEAICEadjMODE now in autodiff_readparms.F
1232    o pkg/seaice:
1233      - remove some store directives and add new ones in an effort to get
1234        finally rid off the recomputation warnings. This is successful
1235        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1236        defined (i.e. no extensive recomputation warnings left), but there
1237        are still too many recomputations on the solver iteration level
1238      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1239      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1240        SEAICE_SIZE.h
1241      - add a store directive in S/R seaice_calc_viscosities
1242    o pkg/seaice (ITD code):
1243      - fix definition of Hlimit for multi-threaded case
1244      - use double precision arithmetic to compute Hlimit: this affects results;
1245        update output of experiment seaice_itd.
1246    o replace content of verification/seaice_itd
1247      - instead of a 1D column use the configuration of offline_exf_seaice
1248        to test the ice thickness distribution code with ridging
1249      - this is a first shot at this experiment
1250      - change of some defaults of ridging parameters SEAICEhStar (from
1251        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1252        and lot of new comments.
1253    
1254    checkpoint64y (2014/06/20)
1255    o pkg/seaice/seaice_reg_ridge.F:
1256      - modify the regularization of very small volumes of ice; only check
1257        total volume HEFF, and do not apply correction to individual ice
1258        classes because that leads to funny patterns in the heat and fw-fluxes
1259        into the ocean. Adjust seaice_itd/results/output.txt
1260      - replace nITD by SEAICE_multDim in loop-ranges
1261    o pkg/exf:
1262      - add code to process the case field period = -12. with UV interpolation.
1263      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1264        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1265    o verification/global_with_exf:
1266      - switch all fields period to -12. (was previously untested) in input/data.exf
1267        (but keep secondary test ".yearly" unchanged); update the reference output.
1268    o pkg/cal:
1269      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1270    o pkg/exf:
1271      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1272        to replace logical switch "exf_verbose"
1273      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1274    o pkg/sbo:
1275      - update from Katherine Quinn: evaluate mass directly from density and SSH
1276        (budget using Finite Volume method) instead of from bottom pressure.
1277      - allow testreport to collect few selected SBO output ; tested in exp.
1278        global_ocean.90x40x15 (after updating the results, to include SBO output).
1279      - fix some multi-threading issues (in output part).
1280    o model/src & most packages:
1281      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1282      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1283        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1284        "data.{pkg}" exist ; and leave the S/R (return) just after.
1285      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1286        + call LAND_READPARMS from packages_readparms.F
1287    o pkg/seaice:
1288      - remove code that resets useThSice in S/R seaice_readparms and
1289        replace it by a warning in S/R seaice_check
1290      - remove parameter MULTDIM, replace with nITD and runtime
1291        parameter SEAICE_multDim (still hard-wired to nITD if
1292        SEAICE_ITD is defined)
1293    
1294    checkpoint64x (2014/05/24)
1295    o verification/lab_sea:
1296      - update adjoint and TLM output following changes to pkg/salt_plume
1297      - un-do the update after putting back local recip_Cp in few places.
1298    o pkg/salt_plume: modifications by An Nguyen:
1299      - add capability to do brine rejection (salt-plume) as function of
1300        volume+tracers (instead of only salinity tracer).
1301      - conserve volume by exchanging volume from each kLev to above to
1302        accommodate in-coming brine volume
1303      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1304      - switch KPP surf buoyancy due to brine forcing to 3-d
1305        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1306      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1307      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1308        in East/West Arctic.
1309    o pkg/sbo:
1310      - incorporate modifications from Katherine Quinn to enable the use of sbo
1311        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1312        output for future testreport verification (unfinished).
1313    o pkg/atm_phys:
1314      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1315        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1316        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1317    o pkg/seaice
1318      seaice_calc_ice_strength.F: modify expression to avoid divisions
1319        (affects truncation)
1320      seaice_do_ridging.F: clean up the insectarium
1321      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1322      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1323      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1324      - add some debugging information and error messages (warnings)
1325    o model/src: modifications relatd to atmosphere p*:
1326      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1327      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1328        of vertical profile tRef in geopotential background and anomaly.
1329      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1330        and pkg/atm_phys.
1331      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1332        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1333    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1334    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1335        not used right now, but can be used in BGC packages to fix conservation.
1336    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1337        other packages too.
1338    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1339        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1340    o model/src:
1341      - since we have several heat capacity (even in model/src), define "recip_Cp"
1342        as local variable (no longer in common block) to avoid any confusion.
1343      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1344    o pkg/exf:
1345      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1346        air density as function of air Temp, Humidity and atm pressure.
1347    
1348    checkpoint64w (2014/05/02)
1349    o verification:
1350      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1351        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1352        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1353        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1354        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1355    o model/src: for atmosphere in p* coords:
1356      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1357      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1358        but not yet activated.
1359    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1360      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1361      - this changes the results (but not for any verification experiment, because
1362        none tests this), but avoids having an extra field in the restart files
1363    o pkg/seaice: remove global variable TICE (not needed)
1364      - replace by TICES or local variable where necessary (cost_seaice_test,
1365        seaice_diagnostics_state)
1366      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1367      - use specific read/write routines for reading and writing individual leves
1368        of a multilevel field
1369    o pkg/ctrl & model/inc:
1370      - move additional anomaly fields of control vars (related to options:
1371         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1372        from DYNVARS.h into new header file: CTRL_FIELDS.h
1373    o pkg/seaice: some small modifications to the ridging code
1374      - make fw2ObyRidge a global variable and add the freshwater flux to
1375        seaice_growth
1376      - pass actual thickness from seaice_prepare_ridging, so that it is
1377        computed only in one place and compute it in the same way as in
1378        seaice_growth
1379      - initialise more fields in seaice_do_ridging that where cause floating
1380        point exceptions over land
1381  o pkg/seaice: preparations for ridging code and first real ridging code  o pkg/seaice: preparations for ridging code and first real ridging code
1382    - move most of "PART 1" of S/R seaice_growth into a new and separate    - move most of "PART 1" of S/R seaice_growth into a new and separate
