5      ==============================      ==============================
6    
7    o coupler pkgs:
8      Start a new way to set-up optionally-exchanged variables (previously, only
9       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
10       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
11       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
12       compononent param default can be set accordingly).
13      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
14       but rather applies to a group a fields (going both ways like for DIC)
15       and corresponds to an option of coupling config.
16      coupler (pkg/atm_ocn_coupler):
17      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
18        and read namelist directly (without eessup S/R calls) instead of
19        in the very un-flexible old way, 1 param per line, in fixed order;
20      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
21        cleanly in CPL_CHECK_CPLCONFIG
22      - add new coupling-exchange selectors (some not yet active) including
23        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
24                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
25      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
26        component ; called directly from coupler.F, after comp. registrations;
27      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
28         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
29          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
30      components (pkg/atm_ & ocn_compon_interf):
31      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
32        CPP header file in all pkg source files.
33      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
34        ATM/OCN_CHECK_CPLCONFIG;
35      - add error-counter to track errors (e.g., in "data.cpl") and to stop
36        cleanly in ATM/OCN_CHECK_CPLCONFIG;
37      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
38        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
39        before PACKAGES_READPARMS;
40      verification/cpl_aim+ocn/:
41      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
42        "data.cpl" for coupler (in input_cpl).
43    o eesupp/inc:
44      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
45        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
46        to always cumulate tile local-sum in the same order (still uses
47        MPI_Allreduce like standard code).
48      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
49        that are now identical to standard version (in eesupp/inc).
50    o pkg/shelfice:
51      - add SHELFICETransCoeffTFile for initializing spatially varying
52        heat and salt transfer coefficients
53    o pkg/atm_compon_interf & ocn_compon_interf:
54      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
55        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
56      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
57    o pkg/atm_ocn_coupler:
58      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
59    o pkg/rbcs:
60      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
61        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
62      - add a short report (to STDOUT) about RBCS-mask settings.
63    
64    checkpoint65p (2015/10/23)
65    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
66        there is no adjoint test for EVP, we don't know what it does to the adjoint
67        solution, but at least there are no more recomputation warnings left
68    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
69        a chance of giving the same results as a fully converged VP (JFNK) solver
70    o tools/adjoint_options/adjoint_diva:
71      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
72    o pkg/streamice:
73      - spotted bug in streamice_driving_stress using dyG where should have been dxG
74    o pkg/exf:
75      - remove STOP statement that prevented to use wind or (wind-)stress
76        interpolation for constant-in-time forcing fields (wind/stress period = 0).
77    o pkg/seaice:
78      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
79        5 additionals 2D fields and 6 new store directives
80      - change logic in seaice_readparms.F: EVP code can now be turned on in
81        various ways, setting SEAICE_deltaTev is no longer required,
82        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
83        or SEAICEaEVPcoeff
84    o pkg/shelfice/shelfice_thermodynamics.F
85      - redefining uLoc/vLoc to u/v, instead of 2u/v
86    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
87      - this is an intermediate state of a truely converging EVP that has
88        the potential of outperforming implicit VP methods, I do not recommend
89        using it yet.
90      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
91        and all parameters are hardwired
92      - for convergence it still requires very smooth regularisations, that means,
93        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
94        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
95        specific averaging appears to be required, still subject to tuning
96      - still needs cleaning and I need to turn parameter into runtime parameters
97      - add code to compute and print residuals of iteration, compile with
98        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
99    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
100      that entered with r1.54 on Sep04, 2015, -> update results
101    
102    checkpoint65o (2015/09/14)
103    o pkg/mom_vecinv & mom_common:
104      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
105        called from there.
106      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
107        allows to use Vector-Invariant form in deep atmos and anelastic formulation
108    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
109      and Koenig-Beatty+Holland (2012)
110      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
111      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
112      - requires an extra input argument for S/R seaice_calc_viscosities
113      - tensileStrength's depth dependence is different from Itkin et al. (2015)
114        (to be changed and played with, for now exponential)
115    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
116      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
117        by AREA according to Connelly et al. (2004), JPO.
118      - For EVP and the LSR solver, the implicit part of the drag term is
119        the only non-zero term in the denominator when there is no ice (which
120        prevented running the model with zero ice-ocean drag). If
121        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
122        (or zero main diagonals BU/BV) which need to be caught. A practical
123        consequence is that for open water, the momentum equation reduce
124        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
125        they happen to be zero, often leading to a non-zero solution over
126        open water.
127    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
128        efficient EVP method.
129      - introduce area-weighted averages for e12 (analogously to
130        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
131        remain, but also changing the order of terms in the previous average
132        changed the results as much) -> update experiment
133      - add SEAICE_DELTA_SMOOTHREG code
134      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
135        TEM-code
136      - adjust loop bounds so that only required fields are computed
137      - add new averaging code for zetaZ/deltaZ (again similar to
138        seaice_calc_viscosities.F), inactive by default for now (will change
139        results again), but will replace old code eventually
140    o eesupp/src:
141      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
142        to always cumulate tile local-sum in the same order
143        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
144        Still uses MPI_Allreduce (like standard code) but on array of tiles
145        and should be faster than GLOBAL_SUM_SEND_RECV code.
146      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
147        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
148      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
149         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
150         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
151         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
152         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
153    
154    checkpoint65n (2015/07/29)
155    o pkg/thsice:
156      - add a warning when used with pkg/aim but without updating SST
157        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
158    o pkg/offline:
159      - change where Offline-Fields are loaded, from load_fields_driver.F to
160        directly within FORWARD_STEP, just after updating iter number and time;
161      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
162        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
163       These changes allow:
164        a) to recover exactly on-line results using deltaToffline=deltaTClock,
165        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
166        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
167        time-step, both with GM & KPP files and with recomputing these fields;
168        b) no needs to switch on staggerTimeStep anymore;
169        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
170      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
171    o pkg/offline:
172      - change (rarely used) offset-iteration parameter to an offset time (in s):
173        can easily recover previous offset-iter effect by setting offset-time
174        (offlineTimeOffset) to offset-iter x deltaToffline;
175      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
176        in KPP as part of surface buoyancy forcing) in offline run.
177      - fix ptracers KPP non-local term in the case where KPP is re-computed.
178    o OpenAD
179      - Adding preliminary ggl90 test to OpenAD verification.
180        Config. with ggl90 currently diverges after 64 time steps
181        so will need more work to become more stable
182      - Adding preliminary kpp test to OpenAD verification.
183        required small tweakes in kpp_routines.F
184      - Merge and update from Krishna Narayanan's contrib area:
185        * Add one variable for preliminary OpenAD DIVA
186        * Add replacement time-stepping for OpenAD DIVA
187        * genmake2 flag -diva (but only for OpenAD; preliminary)
188        * required modifs for OAD_support
189        successful preliminary test for tutorial_global_oce_biogeo/
190    o pkg/seaice:
191      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
192      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
193        delta with a smooth function in s/r seaice_calc_viscosity
194        (no effect on EVP)
195      - rename local suffix "sqr" into "sq" for more consistent variable names
196    o pkg/seaice:
197        add new parameter SEAICE_deltaMin that is used ***only***
198        for regularizing Delta (and nothing else, like the parameter
199        which is also used for all sorts of things SEAICE_EPS).
200        Defaults to SEAICE_EPS for backward compatibility only.
201    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
202        the wrong key by inialising it before use -> fixes a recomputation
203        problem but does not fix the gradient
204    o pkg/layers:
205      - move resetting of flux arrays to outside the iLa loop
206        (this caused layers_diapycnal to not work with more than one layer coord.)
207      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
208    o pkg/layers:
209      - remove from common block 3D layers fields (used to diagnose transport
210        in tracer coords) and declare them as local arrays in layers_calc.F
211    o pkg/seaice:
212      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
213        in lab_sea forward experiment (changes results -> updated)
214      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
215    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
216       computations; for SEAICE_VECTORIZE_LSR
217      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
218        sweep to the outside,
219      - remove store directives and add "CADJ loop sequential" directives
220        in analogy to model/src/solve_tridiagonal.F
221      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
222        boundaries to yield more readable code. This has also the charming side
223        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
224        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
225        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
226        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
227        an additional option)
228       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
229       but the adjoint gradients (which are affected by this change) still explode.
230    o coupler (atm & ocn _compon_interf):
231      - avoid using Exch2 IO mapping if not suitable.
232    
233    checkpoint65m (2015/06/15)
234    o pkg/layers:
235      - clean-up old parameters setting (from Sep 2012):
236        + remove old parameters setting from common block (declared locally);
237        + stop if any old parameter is mixed with new parameters;
238        + check for valid or consistent parameter setting (e.g., layers_name)
239      - check that layers_bounds for Pot.Density are in the right range;
240        this is supposed to catch un-updated setting after recently shifting
241        potential density field "prho" by -1000 (now in "sigma" scale).
242    o pkg/layers:
243      - Added missing call to layers_fill for keeping track of tottend in
244        pkg/diagnostics/diagnostics_fill_state.F
245    o pkg/layers:
246      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
247        of diapycnal fluxes
248    o pkg/layers:
249      - reverted changes to interpolation to previous treatment; there
250        was never actually a problem
251    o pkg/layers:
252      - fix interpolation of layers tracers in the presence of partial cells
253      - add lots of new functionality to compute water mass transformation
254        (enabled by CPP flag LAYERS_THERMODYNAMICS)
255      - add new calls from main code (diags_oceanic_surf_flux.F,
256        thermodynamics.F, impldiff.F) and gad to save the necessary fields
257        for layers_thermodynamics calculations
258    o pkg/ptracers:
259      - add capability of stepping a passive tracer forward without advection
260        by setting PTRACERS_advScheme to 0.
261    o pkg/diagnostics:
262      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
263    o pkg/layers:
264      - shift potential density field "prho" by -1000 for density layer averaging so
265        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
266        Note that density bin boundaries (layers_bounds in data.layers) have
267        to be set accordingly (i.e., shifted, in sigma scale).
268    o pkg/layers:
269      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
270      - fix calculation of layer non-weighted velocity and layer probability
271      - add diagnostics for pot.density used for layer averaging
272    o pkg/seaice:
273      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
274        positiveness, modify a few comments and improve variable names,
275      - the changed computation of deltaC affects most seaice-related
276        experiments at the truncation level.
277        seaice_itd.thermo is affected by far the most, with
278        only 7 digits of agreement remaining; update experiments.
279    
280    checkpoint65l (2015/05/04)
281    o pkg/shelfice:
282      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
283        factor drKp1 to zero where it is negative (ie. do not use
284        SHELFICEBoundaryLayer if hFacC>1)
285      - the same for factor drLoc in shelfice_forcing.F
286    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
287        with modules in ptracers, when using testreport option "-small_f"
288    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
289      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
290    o verification/testreport
291      - add new option -small_f
292        with this option testreport first makes the target small_f (*.f files)
293        before running make (all). This is useful for explicit inlining when
294        all sources need to be full available.
295    o pkg/exf/exf_interp.F:
296        remove previous changes related to reverse (decreasing) input grids latitude
297    
298    checkpoint65k (2015/04/01)
299    o pkg/ecco:
300        fix missing cosphi initialization; use eccoiter in place of optimcycle;
301        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
302        instead of active read/write
303    o pkg/ctrl:
304        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
305        instead of active read/write.
306    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
307        return if .NOT.useAUTODIFF
308    o pkg/seaice: add CPP brackets (cost function related).
309    o model/src:
310        add useAUTODIFF run time switch.
311    o pkg/exf/exf_interp.F:
312        add code to allow input grids with latitude starting in the north (i.e. when
313        j=1 corresponds to northern edge of field); modify global_with_exf to test
314        this feature.
315    o verification/testreport:
316      - replace "grep -A3" with POSIX conformal sed command, because there are
317        implementations of grep that cannot do contextual searches
318      - replace "cat -n" by "nl" (two occurrences), because not all implementations
319        of "cat" have the option "-n"
320    o model/src:
321        add new file gsw_teos10.F that contains 3 functions, more or less a copy
322        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
323        convert from conservative to potential temperature. For now they are not
324        called anywhere.
325    o pkg/ggl90: make "useIDEMIX" useful
326      - re-organize code in s/r ggl90_calc a little to move computations that
327        are different for idemix into separate loops (changes verification
328        experiment idemix at truncation level, 12 digits remain -> updated)
329      - requires 2 new 2D fields KappaM, verticalShear
330      - make hFacI and recip_hFacI local 3D variables that are passed to
331        s/r ggl90_idemix
332      - fix and improve some comments
333    
334    checkpoint65j (2015/02/25)
335    o pkg/openad
336      - synchronize seawater.F with version in model/src: replace routine
337        body of sw_temp by calling sw_ptmp and fix/add a few comments.
338    o pkg/mnc:
339      - change default value of pickup_read/write_mnc params to FALSE
340        (since few features are missing in reading MNC pickup files).
341    o model/src:
342      - change default (background) vertical diffusivity for salt to be the
343        temperature (background) vertical diffusivity.
344      - change background vertical diffusivity in vertical mixing pkgs ggl90,
345        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
346        This makes ptracers default diffusivity (that uses salt diffKr) more
347        consistent with vertical mixing schemes.
348    o verification/testreport:
349      - fix typo in "-pcls" option ;
350      - put temp files in /tmp (instead of in local dir)
351      - add option "-ncad" to use genmake2 new option "-nocat4ad"
352      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
353    o pkg/ggl90 (idemix code):
354      - apply few fixes ; add some missing "_d 0" ; update output of exp.
355        global_ocean.90x40x15.idemix
356    o OpenAD
357      - enable active file I/O and begin removal of work-around code
358        for OpenAD for handling control variables (memory vs. active files)
359      - new CPP options file OPENAD_OPTIONS.h
360      - revert to genarr2d gradient check for hs94.1x64x5
361      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
362      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
363    o tools/genmake2:
364      - add option for an alternative Makefile (from Martin) where multiple
365        source files are sent to TAF (instead of all in one file).
366    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
367      - code provided by Carsten Eden as an extension of ggl90
368      - so far the code is turned on within ggl90 by setting a CPP-flag at
369        compile time; a runtime flag implementation is not yet complete
370      - tested in new verification experiment global_ocean.90x40x15.idemix
371    o verification:
372      - reduce length of the AD test run by half for experiments
373        global_ocean.cs32x15 (std + thsice) and isomip
374      - enable active file I/O for OpenAD, adjust verifications accordingly
375      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
376    o verification/testreport:
377      - fix two non-POSIX sed statements so that there are no error messages
378        on Mac OS X
379      - replace hostname -s with hostname | sed 's/\..*$//'
380    o model/src/seawater.F:
381      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
382        (following the matlab code), which would have avoided the bug caught
383        by Matt (see below) in the first place
384    o pkg/shelfice:
385      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
386        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
387      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
388        ice-shelf case (i.e., within surface level).
389      - add config summary in shelfice_check.F
390      - remove global variable recip_SHELFICElatentHeat and replace by a local
391        variable recip_latentHeat
392      - introduce diagnostics for friction velocity uStar (in case of
393        SHELFICEuseGammaFrict)
394      - change verification experiment isomip.htd:
395        + start from pickup (as input_ad at nIter0=8640)
396        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
397        + test SHELFICEuseGammaFrict = .TRUE.
398        + test SHELFICEadvDiffHeatFlux = .TRUE.
399    o model/src:
400      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
401        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
402        update output of experiments global_with_exf.yearly and isomip (all 6).
403    o pkg/shelfice:
404      - change setting of kTopC to also be zero where there is no ice-shelf.
405      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
406        ice-shelf is.
407      - first attempt to get RealFreshWaterFlux effects: for now, only without
408        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
409    o pkg/seaice: add the option to prescribe a fixed thickness PDF
410      for thermodynamic calculations
411      - because of divisions of the type 7/7 not exactly equal to 1, this change
412        affects results of some verification experiments by up to 4 digits:
413        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
414        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
415        adjoint: lab_sea, lab_sea.noseaicedyn
416        -> updated
417    
418    checkpoint65i (2015/01/23)
419    o model/src:
420      - change units of frictionHeating field from W to W/m^2
421      - fix bug in frictional heating from stratospheric drag in
422        S/R ATM_PHYS_TENDENCY_APPLY_V
423      - with synchronous time-stepping: move resetting to zero of frictionHeating
424        field from load_fields_driver.F to thermodynamics.F ;
425      - add diagnostics for frictional heating.
426    o model/src & gmredi K3D:
427      - add frictionHeating field to pickup-files (for synchronous time-stepping)
428      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
429      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
430        and name in pickup file).
431      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
432    o model/src:
433      - move (from ini_forcing.F) initialisation of all arrays in header file
434        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
435        (since Nov 2012) with option selectAddFluid=1.
436    o pkg/shelfice:
437      - change units (+ document) of newly added field "shelfIceMassDynTendency"
438      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
439    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
440    o pkg/seaice: two new runtime parameters:
441      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
442        long overdue
443      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
444        parameterization of tensil stress for fast ice (does not do anything yet)
445    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
446        for LSR: move checking overlaps out of JFNK-if-block
447    o pkg/atm_phys:
448      - move copy of grid and dynamical fields out of atm_phys_driver.F into
449        new S/R ATM_PHYS_DYN2PHYS.
450      - fix level height for Linear Free-Surf case (to be consistent with
451        fixed-in-time pressure levels).
452    o pkg/mom_common (bottomdrag):
453      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
454        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
455        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
456    o pkg/shelfice (u/v_drag):
457      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
458      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
459        (now similar to shelfice_u_drag.F)
460      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
461        from mom_vecinv.F (similar to mom_fluxform calls).
462    o pkg/mom_common (bottomdrag):
463      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
464      - add options for alternative discretisation of velocity norm in quadratic
465        bottom drag: averaging of grid-cell-center KE to U.point and V.point
466        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
467        improves when averaging only the other component (e.g. vVel for U bottom
468        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
469      - add options (bottomVisc_pCell) to account for partial-cell in bottom
470        friction (no-slip BC) thus getting the true distance from the bottom;
471        off by default since this also reduces model stability (explicit bottom
472        friction). Changes produce different machine truncation with linear-drag
473        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
474        front_relax (bvp & mxl, 10 & 11 digits).
475    o model/src & mom pkgs:
476      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
477        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
478      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
479        just copy level Nr value to level Nr+1.
480    o doc:
481      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
482    o pkg/streamice:
483      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
484        SHELFICE.h: move array shelficemass to init_varia, initialise
485        from array shelficemassinit, which is set in init_fixed and
486        has option to be set from file; introduce array
487        shelficeMassDynTend array, set thru file in init_fixed
488      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
489        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
490        pkg/streamice
491      - shelfice_thermodynamics.F: call shelfice_step_icemass if
492        SHELFICEMassStepping = .true.
493      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
494    
495    checkpoint65h (2014/12/17)
496    o verification/global_ocean.90x40x15, global_ocean_ebm:
497      - update to generic controls.
498    o pkg/ctrl:
499      - ctrl_map_ini_genarr.F: test for igen>0
500      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
501      - move gentim2d part of ctrl_map_ini_genarr.F to
502        new separate routine : ctrl_map_ini_gentim2d.F
503      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
504        add time variable weights and cyclic controls (time mean,
505        seasonal cycle, etc) capabilities to gentim2d
506    o pkg/ecco:
507      - move reading of error, conversion to weights from
508        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
509    o global_oce_llc90, cs32:
510      - activte sbo.
511      - CTRL_SIZE.h : add maxCtrlProc.
512      - activate the new genctrl capabilities.
513      - update following reorganization of global_oce_input_fields.tar.gz  
514    o pkg/ctrl/ctrl_ad_diff.list:
515      - add missing ctrl_init_rec.f
516    o tools/OAD_support/keepOriginal:
517      - add ctrl_init_rec.F
518    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
519      - avoid recomputations of xx_gentim2d_dummy.
520    o momentum diagnostics:
521      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
522        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
523    o pkg/seaice/seaice_lsr.F:
524      - fix computation of BU/BV, make sure they are non-zero, only necessary
525        for cubed sphere exchanges and SEAICE_OLx/y>0.
526        This makes calling s/r fill_cs_corner_rl obsolete (removed).
527    o verification/global_ocean.cs32x15/input.seaice
528      - add test for strong implicit coupling and restricted addtive Schwarz
529        methods for LSR
530      - update results/output.seaice.txt
531    o verification/tutorial_global_oce_biogeo:
532      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
533        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
534        update output_adm,_oadm,_tlm.txt
535    o pkg/dic:
536      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
537      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
538        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
539    o verification/tutorial_global_oce_biogeo:
540      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
541        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
542        update output_adm,_oadm,_tlm.txt
543    o eesupp/src:
544      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
545        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
546    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
547      LSR (following Hutchings et al. 2004)
548      - introduce zetaZ as a global variable (requires adjustments in
549        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
550        in seaice_calc_viscosities.F
551      - new flag SEAICEuseStrImpCpl (default off)
552      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
553        momentum equations
554      - JFNK-solver (preconditioner) adjusted to allow using this method
555        (where it does not have any positive effect)
556    o pkg/seaice
557      - add overlap for restrictive additive Schwartz method also to LSR, but
558        turn it off by default (because it only seems to work for non-cubed
559        sphere/llc topologies)
560    o pkg/autodiff
561      - add extra exchanges in addummy_in_steppging also for mnc output
562    o pkg/seaice:
563      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
564        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
565    o pkg/obcs:
566      - add option to specify domain-connected piece Id along OB though files
567        (for now, only used to diagnose PhiVel; default =1 -> global correction)
568      - modify obcs_diag_balance.F to process each connected-part separately;
569        exclude OB where Id = 0 but keep the full divergence there (-> constant
570        Psi along this portion of OB and all inflow derived from grad(Phi))
571      - add example of OB-conect files in verification/so_box_biogeo/input.
572    o pkg/diagnostics:
573      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
574      a) use non zero matrix element across OB and solve for Phi 1 grid point
575         outside OB (i.e, where tracer OBCS are applied).
576      b) global imbalance of inFlow/outFlow across OB: instead of modifying
577         velocity across OB, spread it uniformly along the OB in the RHS.
578    
579    checkpoint65g (2014/11/19)
580    o pkg/diagnostcis:
581      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
582    o pkg/my82,pp81,kl10:
583      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
584        field diffKr as background diffusivity to set minimum diffusivity value.
585    o pkg/seaice:
586      - add new parameter SEAICEuseEVPrev (for revisited EVP by
587        Bouillon et al 2013)
588      - add SEAICE_evpAlpha/Beta to namelist
589      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
590        involve trivial re-ordering of divisions/multiplications that should not
591        have any effects, but ... they do change the results of lab_sea.hb87 so
592        that only 2 digits of agreement remain, in line with the general
593        instability/fragility of the evp-code. For now, I do not care and just
594        update the verification experiment
595    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
596      - remove xx_genarr2d_numsmooth etc
597      - use xx_genarr2d_preproc etc instead
598      - carry out smooth_correl2D at initialization stage rather than during
599        time stepping.
600      - get smoothOpNb from xx_gentim2d_preproc
601    o global_oce_cs32 :
602      - add test of generic ecco capabilities.
603    o pkg/exf/exf_getsurfacefluxes.F :
604      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
605    o pkg/ctrl,ecco :
606      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
607        is defined.
608    o pkg/seaice: add diagnostics for Delta (deformation parameter)
609    o model/src:
610      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
611        diffusivity (background) is specified but ignored.
612    o verification:
613      - in testreport, convert hostname to lower case for default output dir name
614    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
615    o pkg/dic: add modifications from Hajoon:
616      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
617      - light attenuation: add self-shading effect by climatological Chlorophyll
618        (read from file).
619    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
620        compiles when SEAICE_ALLOW_DYNAMICS is undefined
621    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
622        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
623        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
624        approach where CPP_OPTIONS.h includes an omnipotent
625        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
626    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
627        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
628    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
629        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
630        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
631    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
632      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
633      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
634      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
635      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
636    o pkg/ctrl,ecco,exf :
637      - remove variables associated with NON-generic costs,
638        unless ECCO_CTRL_DEPRECATED is defined.
639      - remove NON-generic NON-obcs controls,
640        unless ECCO_CTRL_DEPRECATED is defined.
641    o pkg/ctrl : added ctrl_local_params.h
642    o pkg/ecco : added ecco_local_params.h
643    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
644        experiments, which will progressively be removed once the
645        experiments are revised to use only generic controls/costs.
646    
647    checkpoint65f (2014/10/13)
648    o pkg/ctrl, ecco, seaice : minor changes in headers
649    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
650        cost function and control capabilities added since checkpoint65c.
651    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
652    o pkg/ecco: increase modularity and improve logic
653      - ecco_toolbox.F (new) : basic operations that are often used,
654        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
655        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
656      - cost_gencal.F (new) : determine filnames and records.
657      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
658      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
659        and exploit the above functions leading to more compact code.
660      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
661      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
662        using_ers, using_gfo, using_mdt is now only defined within gencost)
663    o pkg/ecco: extend generic cost capabilities
664      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
665        capabilities via gencost_preproc (+ _c,_i,_r related params),
666        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
667        gencost_outputlevel arguments to cost_generic
668      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
669        and active_read, making room for gencost_preproc to take effect.
670        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
671      - pkg/ecco/cost_generic.F :
672        compute and store misfit maks*(model-data) in localdif that is
673        then used in cost and for output, output misfit if outlev.GT.0
674      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
675        rather gencost_barfile for deciding whether to write barfile
676      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
677      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
678        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
679      - pkg/ecco/ecco_summary.F : report gencost variables
680      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
681    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
682    o pkg/ecco: internal re-organization
683      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
684        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
685        mv relevant variables definition from ecco_cost.h to ecco.h,
686        make sure gencost routines only include ecco.h)
687      - throughout : add missing CCP switches, rm unused variables,
688        and rm un-necessary CPP switches
689      - throughout gencost routines : replace modelstartdate with
690        gencost_startdate when needed
691      - cost_bp_read.F : use arguments, instead of common blocs
692        so that it can be used also by (new) cost_gencost_bpv4.F
693      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
694      - ecco_phys.F : compute etanFull
695      - ecco_readparms.F : rename using_topex as using_tpj, add
696        bpv4-grace to gencost list, initialize added parameters
697      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
698    
699    checkpoint65e (2014/09/28)
700    o pkg/obcs:
701      - replaced the just-added CPP options with run-time variables
702        (see pkg/obcs/OBCS_PARAMS.h for details)
703    o pkg/obcs:
704      - add additional CPP options for sponge boundary layers
705        (see pkg/obcs/OBCS_OPTIONS.h for details)
706    o pkg/atm_phys:
707      - implement simple (obliquity only, assuming circular planet orbit)
708        seasonal cycle for incoming insolation ; used when run-time parameter
709        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
710    o pkg/exf, pkg/ecco, pkg/ctrl:
711      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
712      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
713      - implement gentim2d for xx_tauu, xx_tauv
714    o pkg/ctrl, pkg/ecco :
715      - fix and complement the generic controls implementation
716    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
717        pkg/shelfice/shelfice_thermodynamics.F,
718        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
719        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
720      - add weight in CTRL_GET_GEN calls
721    o pkg/ctrl :
722      - ctrl_get_gen.F : add weight as input parameter, and apply
723        it directly rather than using smooth_correl2Dw (to be retired).
724      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
725    o pkg/ctrl :
726      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
727        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
728      - re-activate ctrl_summary (call in ctrl_init.F)
729    o pkg/ctrl/ctrl_cost_gen.F :
730      - fix CCP brackets, remove un-necessary myiter, mytime
731    o pkg/ecco, pkg/ctrl :
732      - remove cost_genctrl.F (now pkg/ctrl/ctrl_cost_driver.F)
733      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
734      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
735      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
736    
737    checkpoint65d (2014/09/15)
738    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
739      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
740        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
741    o pkg/ctrl/ctrl_map_ini_genarr.F :
742      - remove compilation failure
743      - replace hard coded example
744      - use ctrl_map_ini_gen2D, 3D
745    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
746      - on/off switch based upon xx_genarr2d_weight,3d
747    o src/packages_init_variables.F :
748      - regroup pkg/estimation calls
749      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
750        (moved to ctrl_init_variables)
751    o cost/cost_init_varia.F :
752      - remove ecco_cost_init_varia
753        (moved to ecco_init_varia)
754    o ctrl/ctrl_init_variables.F :

756      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
757    o ctrl/ctrl_map_ini.F :
758      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
759        (moved to ctrl_init_variables)
760    o ctrl/ctrl_map_ini_ecco.F :
761      - remove ECCO_PHYS (mv to ecco_init_varia)
762      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
763    o ecco/ecco_ad_diff.list :
764      - add ecco_init_varia.f
765    o ecco/ecco_init_varia.F
766      - new routine
767    o pkg/streamice:
768      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
769        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
770      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
771    o pkg/generic_advdiff:
772      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
773    o pkg/exf:
774      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
775         xxg_precip capability
776      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
777    o pkg/ctrl:
778      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
779    o model/src/load_fields_driver.F :
780      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
781        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
782    o OpenAD verification experiments:
783      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
784        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
785        for now, only in pkgs used in OpenAD verification experiments.
786      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
787        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
788        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
789        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
790    o OpenAD verification tests:
791      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
792      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
793        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
794      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
795        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
796    o model/src & generic_advdiff:
797      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
798        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
799        dynamics requires valid tracer forcing only over tile interior but, for
800        some diagnostics, may need to extend it over 1 point in tile halo region.
801      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
802        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
803        setting in temp/salt/ptracer_integrate.F
804    o pkg/dic:
805      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
806        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
807        in gchem_forcing_sep.F
808    o pkg/autodiff & obcs:
809      - add storage of current OB values for U & V (was already done for T & S).
810    
811    checkpoint65c (2014/08/30)
812    o pkg/dic:
813      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
814        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
815        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
816    o verification:
817      - new experiment testing OBCS and DIC pkgs, using params & output from
818        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
819        passage: take OBCS from the last year of a 2 yrs simulation and initial
820        conditions from t=1.yr while keeping the same forcing.
821    o model/src:
822      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
823        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
824    o pkg/diagnostics (Stats-Diags):
825      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
826        a) refine region where stats are computed, excluding where arrhFac=0 ;
827        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
828        c) extend regional stats over the region edges (for U or V pt location).
829    o pkg/gchem:
830      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
831        pkg/dic is currently changing/updating ptracers values beyond the OB).
832    o verification (hs94):
833      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
834        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
835        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
836        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
837    o pkg/ptracers:
838      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
839        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
840      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
841        with AB-2 code (so that it get tested).
842    o model/src:
843      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
844        with AB-2 code (previously only available with AB-3 code).
845        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
846        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
847        there, by calling CYCLE_AB_TRACER).
848    o pkg/generic_advdiff:
849      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
850        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
851        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
852        S/R temp/salt/ptracers_integrate.F
853    o model/src & pkg/ptracers:
854      - remove common block variables gT,gS (in DYNVARS.h), except when
855         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
856      - remove common block variable gPtr.
857    o model/src & pkgs:
858      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
859         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
860         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
861         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
862      + change accordingly all calling S/R.
863      - use local temperature/salinity/ptracer tendency array (without bi,bj)
864        in S/R temp/salt/ptracers_integrate.F
865    o pkg/seaice:
866      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
867        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
868      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
869        in seaice_lsr
870      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
871        in s/r seaice_lsr_calc_coeffs
872    o pkg/mdsio:
873      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
874        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
875        too long (e.g., > MAX_LEN_FNAM/2 )
876    
877    checkpoint65b (2014/08/12)
878    o pkg/matrix:
879      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
880    o model/src:
881      - fix initialisation of geothermalFile; compile geothermal-flux code in
882        natl_box verification experiment.
883    o model/src & pkg/down_slope:
884      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
885      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
886        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
887        results at machine truncation level: update output of experiments
888        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
889    o pkg/diagnostics (Stats-Diags):
890      - do not cumulate the full volume when DIAGNOSTICS_FILL is
891        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
892        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
893        times (but Min,Max and StD are still wrong).
894    o model/src:
895      - add geothermal flux forcing: read in ini_forcing.F as time-constant
896        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
897    o model/src:
898      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
899        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
900        arrays are already updated while adjustments (filters, conv.adjustment) are
901        still applied later, in S/R TRACERS_CORRECTION_STEP.
902    o model/src:
903      - store in common bloc array "rhoInSitu" the virtual potential temperature
904        anomaly that is used to compute geopotential: this make the atmos code
905        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
906    o pkg/seaice/seaice_lsr.F
907      - rename integer variable ilcall to ipass (that's what it is called
908        in the residual diagnostics
909      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
910        default) for improved non-linear convergence of the first few steps
911      - adjust a few comments and add new ones to explain some of the store
912        directives
913    o pkg/generic_advdiff (& ptracers):
914      - re-work the code to check for valid advection scheme and for minimum
915        size of overlap (now stored in local common bloc in gad_advscheme.F)
916    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
917      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
918      - add an auxilliary variable "bet" and fix store directives and keys in
919        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
920        less exact gradients in my tests); but there are still
921        recomputation warning (although gradients are sort of OK), when
922        SEAICE_LSR_VECTORIZE is not defined, so this flag and
923        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
924      - update verification experiments lab_sea.
925      - change some comments in S/R seaice_calc_viscosities
926    o model/src:
927      - if staggerTimeStep=T, always apply exchange to velocity field in
928        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
929        (independent of using multi-dim advection or not); no effect on FWD run
930        but affects AD results (at machine truncation level): update output of
931        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
932        and isomip (oad: 12.d).
933    o pkg/generic_advdiff:
934      - stop if doAB_onGtGs is set to FALSE but ignored
935      - refine warning related to stability of tracer time-stepping
936        regarding internal wave dynamics.
937      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
938        on staggerTimeStep & implicitIntGravWave (will now get a warning
939        if potentially unstable).
940    o pkg/kl10:
941      - add new pkg "kl10" for mixing due to internal wave breaking, from
942        http://www.sciencedirect.com/science/article/pii/S1463500310000144
943        (contribution from Jody Klymak), tested in verification experiment
944        verification/internal_wave/input.kl10/
945    o isomip experiment:
946      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
947        (input.htd) and update the output.
948    o cd_code experiments:
949      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
950        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
951        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
952        update the corresponding output.
953    o pkg/seaice:
954      - reduce the number of include files and store directives in
955        S/R seaice_lsr_tridiagu/v
956      - change the order of loops in one case in S/R seaice_lsr_tridiagv
957        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
958        get rid off one store directive (a TAF bug?)
959      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
960        S/R seaice_lsr_tridiagv to change the loop range for consistency
961      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
962      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
963        S/R seaice_lsr_tridiagu/v (requires update of
964        offline_exf_seaice/input.dyn_jfnk)
965    
966    checkpoint65a (2014/07/27)
967    o model/src:
968      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
969        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
970        (topo in p-coords, ice-shelf in z-coords); update output of experiments
971        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
972    o model/src:
973      - collect momentum forcing tendency into local 2-D array (passed as argument
974        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
975        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
976        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
977      - collect T & S forcing tendency into local 2-D array (passed as argument to
978        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
979        affects results at machine truncation level (e.g., ocean: if using
980        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
981        correction due to vertical advection).
982      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
983        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
984        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
985        obcs_ctrl (ad & fwd grd @ 12 & 7).
986    o pkg/ptracers & diagnostics:
987      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
988        title (to avoid some unexpected truncation); sort out ptracers diags units.
989      - collect ptracer forcing tendency into local 2-D array (passed as argument
990        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
991    
992    checkpoint65 (2014/07/18)
993    o pkg/fizhi:
994      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
995        affects results at machine truncation level. Update output of experiments
996        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
997    o pkg/seaice: more clean up
998      - rename TAF common block tapes to be more consistent and remove
999        unnecessary duplicates
1000      - add store directives to remove more recomputations, but use smaller
1001        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1002        The idea behind this flag is to reduce the memory footprint when the
1003        adjoint of the LSR is not required. As of now, defining the flag
1004        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1005        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1006        For experiment offline_exf_seaice, this means on a linux box with gfortran
1007        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1008        this experiment):

1013        but only a moderate increase of 36% for global_ocean.cs32x15:
1014        text    data        bss     dec        hex
1015        6695027 1648 1014578664 1021275339 3cdf6ccb
1016        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1017      - note: there are still recomputations in global_ocean.cs32x15 and
1018        offline_exf_seaice and the gradient agreement changes (gets a
1019        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1020      - in general, the AD gradients still are wrong
1021    o OpenAD
1022      - clean up code_oad/ directories somewhat by moving files
1023        dontCompile, dontTransform, keepOriginal to OAD_support/
1024    o model/src:
1025      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1026        (not currently tested): add dissipation terms before NLFS rescaling of
1027        tendencies (previously done after).
1028    o pkg/diagnostics:
1029      - write stats-diags in ascii file with more digits (same as in monitor).
1030    o pkg/down_slope:
1031      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1032        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1033    o model/src:
1034      - new file "apply_forcing.F" containing all the code previously in
1035        external_forcing.F, but with new argument list: pass, as new argument,
1036        the current level tendency array to update (instead of a direct update
1037        of the common bloc array). Change the corresponding calls.
1038      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1039        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1040    o pkg/seaice/seaice_lsr, a little bit of clean up
1041      - rearrange some code blocks, so that now all calculations for
1042        setting up the right-hand-sides done within one single block
1043        (I find that easier to read and understand)
1044      - rearrange freedrift-code to reduce the number of ifdefs
1045      - adjust some indentations and comments
1046    
1047    checkpoint64z (2014/07/10)
1048    o model/src and several pkgs:
1049      - change argument list of all S/R called from external_forcing.F and
1050        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1051        to pass, as argument, the current level tendency array to update
1052        (instead of a direct update of the common bloc array).
1053      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1054      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1055    o pkg/seaice/seaice_lsr.F
1056      - always initialize local arrays in seaice_lsr_tridiagu/v
1057      - add more local tapes to seaice_lsr_tridiagu/v
1058      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1059        keep it in bi/bj loop; this seems to be essential
1060      - gradients are still wrong but only by 4-7 orders of magnitude
1061        instead of 15 orders of magnitude, lab_sea improves a little
1062    o pkg/seaice
1063      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1064        generates unnecessary code in seaice_lsr_ad
1065      - add more store directives in seaice_lsr to avoid unnecessary code
1066        in seaice_lsr_ad
1067      - exclude some residual computations in seaice_lsr when
1068        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1069        in seaice_lsr_ad
1070      - add more storing, a new tape (model/src/the_main_loop.F) and
1071        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1072        and klockey should be checked by a specialist)
1073      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1074        and update lab_sea after previous changes in pkg/seaice below
1075    o pkg/autodiff:
1076      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1077        viscFacInAd : run time parameters allowing for adjoint switches
1078        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1079    o pkg/ecco:
1080      - introduce cost_gencost_boxmean.F that computes a box mean
1081        temperature (for use in adjoint sensitivity studies).
1082    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1083    o pkg/mom_common/mom_calc_visc.F:
1084      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1085    o pkg/seaice/seaice_summary.F:
1086      - statement for SEAICEadjMODE now in autodiff_readparms.F
1087    o pkg/seaice:
1088      - remove some store directives and add new ones in an effort to get
1089        finally rid off the recomputation warnings. This is successful
1090        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1091        defined (i.e. no extensive recomputation warnings left), but there
1092        are still too many recomputations on the solver iteration level
1093      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1094      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1095        SEAICE_SIZE.h
1096      - add a store directive in S/R seaice_calc_viscosities
1097    o pkg/seaice (ITD code):
1098      - fix definition of Hlimit for multi-threaded case
1099      - use double precision arithmetic to compute Hlimit: this affects results;
1100        update output of experiment seaice_itd.
1101    o replace content of verification/seaice_itd
1102      - instead of a 1D column use the configuration of offline_exf_seaice
1103        to test the ice thickness distribution code with ridging
1104      - this is a first shot at this experiment
1105      - change of some defaults of ridging parameters SEAICEhStar (from
1106        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1107        and lot of new comments.
1108    
1109    checkpoint64y (2014/06/20)
1110    o pkg/seaice/seaice_reg_ridge.F:
1111      - modify the regularization of very small volumes of ice; only check
1112        total volume HEFF, and do not apply correction to individual ice
1113        classes because that leads to funny patterns in the heat and fw-fluxes
1114        into the ocean. Adjust seaice_itd/results/output.txt
1115      - replace nITD by SEAICE_multDim in loop-ranges
1116    o pkg/exf:
1117      - add code to process the case field period = -12. with UV interpolation.
1118      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1119        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1120    o verification/global_with_exf:
1121      - switch all fields period to -12. (was previously untested) in input/data.exf
1122        (but keep secondary test ".yearly" unchanged); update the reference output.
1123    o pkg/cal:
1124      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1125    o pkg/exf:
1126      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1127        to replace logical switch "exf_verbose"
1128      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1129    o pkg/sbo:
1130      - update from Katherine Quinn: evaluate mass directly from density and SSH
1131        (budget using Finite Volume method) instead of from bottom pressure.
1132      - allow testreport to collect few selected SBO output ; tested in exp.
1133        global_ocean.90x40x15 (after updating the results, to include SBO output).
1134      - fix some multi-threading issues (in output part).
1135    o model/src & most packages:
1136      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1137      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1138        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1139        "data.{pkg}" exist ; and leave the S/R (return) just after.
1140      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1141        + call LAND_READPARMS from packages_readparms.F
1142    o pkg/seaice:
1143      - remove code that resets useThSice in S/R seaice_readparms and
1144        replace it by a warning in S/R seaice_check
1145      - remove parameter MULTDIM, replace with nITD and runtime
1146        parameter SEAICE_multDim (still hard-wired to nITD if
1147        SEAICE_ITD is defined)
1148    
1149    checkpoint64x (2014/05/24)
1150    o verification/lab_sea:
1151      - update adjoint and TLM output following changes to pkg/salt_plume
1152      - un-do the update after putting back local recip_Cp in few places.
1153    o pkg/salt_plume: modifications by An Nguyen:
1154      - add capability to do brine rejection (salt-plume) as function of
1155        volume+tracers (instead of only salinity tracer).
1156      - conserve volume by exchanging volume from each kLev to above to
1157        accommodate in-coming brine volume
1158      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1159      - switch KPP surf buoyancy due to brine forcing to 3-d
1160        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1161      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1162      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1163        in East/West Arctic.
1164    o pkg/sbo:
1165      - incorporate modifications from Katherine Quinn to enable the use of sbo
1166        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1167        output for future testreport verification (unfinished).
1168    o pkg/atm_phys:
1169      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1170        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1171        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1172    o pkg/seaice
1173      seaice_calc_ice_strength.F: modify expression to avoid divisions
1174        (affects truncation)
1175      seaice_do_ridging.F: clean up the insectarium
1176      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1177      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1178      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1179      - add some debugging information and error messages (warnings)
1180    o model/src: modifications relatd to atmosphere p*:
1181      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1182      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1183        of vertical profile tRef in geopotential background and anomaly.
1184      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1185        and pkg/atm_phys.
1186      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1187        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1188    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1189    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1190        not used right now, but can be used in BGC packages to fix conservation.
1191    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1192        other packages too.
1193    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1194        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1195    o model/src:
1196      - since we have several heat capacity (even in model/src), define "recip_Cp"
1197        as local variable (no longer in common block) to avoid any confusion.
1198      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1199    o pkg/exf:
1200      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1201        air density as function of air Temp, Humidity and atm pressure.
1202    
1203    checkpoint64w (2014/05/02)
1204    o verification:
1205      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1206        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1207        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1208        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1209        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1210    o model/src: for atmosphere in p* coords:
1211      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1212      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1213        but not yet activated.
1214    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1215      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1216      - this changes the results (but not for any verification experiment, because
1217        none tests this), but avoids having an extra field in the restart files
1218    o pkg/seaice: remove global variable TICE (not needed)
1219      - replace by TICES or local variable where necessary (cost_seaice_test,
1220        seaice_diagnostics_state)
1221      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1222      - use specific read/write routines for reading and writing individual leves
1223        of a multilevel field
1224    o pkg/ctrl & model/inc:
1225      - move additional anomaly fields of control vars (related to options:
1226         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1227        from DYNVARS.h into new header file: CTRL_FIELDS.h
1228    o pkg/seaice: some small modifications to the ridging code
1229      - make fw2ObyRidge a global variable and add the freshwater flux to
1230        seaice_growth
1231      - pass actual thickness from seaice_prepare_ridging, so that it is
1232        computed only in one place and compute it in the same way as in
1233        seaice_growth
1234      - initialise more fields in seaice_do_ridging that where cause floating
1235        point exceptions over land
1236  o pkg/seaice: preparations for ridging code and first real ridging code  o pkg/seaice: preparations for ridging code and first real ridging code
1237    - 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
