# Line 5  $Name$ Line 5  $Name$
5      ==============================      ==============================
6    
7  o model/src:  o model/src:
8      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
9        added phi0Ref) to set vertical axis origin and phiRef origin;
10        keep Ro_SeaLevel for backward compatibility (with a warning).
11       According to coordinate and fluid type:
12        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
13        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
14        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
15        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
16    o pkg/seaice/seaice_evp.F
17      - simplify computation of deltaZ and zetaZ to simple averaging following
18        Bouillon et al. (2013). This removes a lot of code, but also changes
19        verification experiment lab_sea.hb87 -> updated
20    
21    checkpoint65u (2016/03/14)
22    o pkg/generic_advdiff:
23      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
24        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
25        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
26        testing and not for actual use.
27    o model/src:
28      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
29        origin r = rF(1);
30      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
31        in EOS for height coordinate: enable to include NH Pressure or to use
32        more accurate pressure vertical profile; options not linked to EOS type
33        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
34      - start to implement variable gravity (along vertical): for now, only with
35        z-coords (not even z*).
36      - add Ideal Gas equation of state for height coordinate.
37      - update OpenAD output (affected at machine truncation level) of exp:
38        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
39    o pkg/exf:
40      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
41        of exf interpolation (before any rescaling, rotation or interpolation
42        to velocity point) for each field that gets loaded from file. This option
43        identically mimics the input file organization (e.g. record numbers in year
44        by year input files) besides the change in horizontal grid.
45      - add rotateStressOnAgrid run-time switch so that wind stress fields
46        can be provided on the A-grid in zonal/meridional direction and
47        rotated on the fly. This only applies to the case when the exf
48        interpolation is off and rotateStressOnAgrid is false by default.
49    o model/src:
50      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
51        it's also used with pkg/atm_phys) and add few more parameters (but still
52        inactive, src code yet to come)
53    
54    checkpoint65t (2016/02/10)
55    o pkg/atm_phys:
56      - from Ruth Geen: add optical depth dependence on CO2 concentration.
57    o model/src:
58      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
59        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
60        Update output of exp. deep_anelastic (changes at truncation level).
61    o tools:
62      - add a hack in "remove_comments_sed" (used only with TAF) for recent
63        version of OpenMPI (shipped with FC.23): comment out the new header
64        file "mpif-sizeof.h" which causes problems to TAF.
65    o pkg/seaice:
66      - change the termination criterion so that maxits (SEAICElinearIterMax)
67        has an effect
68      - unify iteration parameters for implicit solvers (JFNK and Picard)
69        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
70        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
71        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
72        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
73        SEAICEnonLinTol     replaces JFNKgamma_nonlin
74      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
75      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
76        use with SEAICEuseKrylov
77    o pkg/seaice/seaice_lsr.F
78        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
79        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
80        an effect.
81    o pkg/seaice: add two new parameters
82      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
83        parameter is not in any namelist)
84      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
85        a preconditioner for the non-linear Newton iteration of the JFNK
86        solver
87    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
88      affects some experiments at truncation level:
89      - global_ocean.cs32x15.icedyn (11 digits),
90      - global_ocean.cs32x15.seaice (11 digits),
91      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
92      - also update global_ocean.cs32x15 adjoint and tangent-linear results
93    o pkg/salt_plume & pkg/thsice:
94      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
95        connect salt_plume flux to ATM-OCN coupling pkgs interface:
96       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
97         export to coupler interface) even without compiling pkg/salt_plume ;
98       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
99         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
100    o pkg/dic:
101      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
102        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
103        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
104      - move also update with values from ATM-OCN Coupler in the same new S/R
105        (previously done in ocn_apply_import.F).
106    o tools/adjoint_options:
107      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
108        has been changed on Jan 14, 2016.
109    o pkg/ggl90:
110      - add alternative discretisation of vertical shear (off by default), to
111        compute the mean (@ grid-cell center) of vertical shear compon instead of
112        vertical shear of mean flow (@ grid-cell center).
113      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
114        results on adjacent faces of cubed-sphere grids; this fix the restart.
115    o pkg/atm_compon_interf:
116      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
117        pass last value, stored directly before export to CPL ;
118        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
119      - remove atmSLPr from pickup files (no longer needed for restart)
120    
121    checkpoint65s (2016/01/13)
122    o eesupp & genmake2:
123       - first check for Function ETIME and, if it fails, then check for subroutine
124         ETIME and consistent output; use the appropriate version in timers.F
125    o model/src:
126      - to check restart test, add option to apply EXCH to U,V earlier, just before
127        integr_continuity; turned off by default.
128    o pkg/dic:
129      - remove CPP option USE_ATMOSCO2 (not needed)
130    o tools/tst_2+2:
131      - try to ignore difference between +0 and -0 in binary file, causing test
132        to fail for no good reason.
133    o eesupp & genmake2:
134      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
135        but also check (in genmake2) that test runs and returns meaningful results.
136    o coupler pkgs:
137      Finish implementation of optionally-exchanged variable switches (started on
138       Nov 12) with addition of few more exchanged fields, including 2-way exchange
139       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
140       advection in OCN component; this requires sequential coupling.
141      coupler (pkg/atm_ocn_coupler):
142      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
143        routines (useful for debug).
144      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
145         flux, DIC fields) if corresponding switch is ON.
146      - add option to export RunOff to OCN (to use for DIC river input)
147      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
148      components (pkg/atm_ & ocn_compon_interf):
149      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
150        optionally exchanged fields; add a check & stop in cpl_readparms.F.
151        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
152        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
153      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
154        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
155      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
156      - hold in common block coupler optionally-exchanged variable switch
157        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
158      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
159        this is intended to replace the OCN cplFldtave.* output files (not updated
160        to contain new additional exchanged fields).
161    o pkg/dic:
162      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
163    o pkg/thsice:
164      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
165        and writing of thsice pickup files.
166    o pkg/atm_compon_interf:
167      - move all field individual export-call out of cpl_export_import_data.F
168        into new S/R ATM_EXPORT_FIELDS
169    o pkg/atm_compon_interf:
170      - store state variables (for now, only thSIce fields) just before beeing
171        exported (in cpl_export_import_data.F, like on ocean side) instead of from
172        atm_store_my_data.F like all exported fluxes.
173      - new version of pickup_cpl: write field names into meta file and read meta
174        file to find field postion in pickup. Also only write/read fields meeded for
175        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
176    o pkg/dic:
177      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
178    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
179        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
180        value can be from domain [0,1] to average between the two methods
181    o pkg/atm_phys:
182      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
183        hold fixed in time).
184    
185    checkpoint65r (2015/12/21)
186    o pkg/seaice:
187        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
188        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
189    o pkg/seaice:
190      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
191        when SEAICEscaleSurfStress=.TRUE.,
192      - apply areaW and areaS in S/R seaice_calc_lhs
193    o pkg/atm_phys:
194      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
195        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
196        for individual contribution (convection, LSC cond, radiation)
197      - add Ruth Geen etal, GRL 2016, radiation optionis (see paper supp.
198        information); activated with: solar_exponent=0. and wv_exponent=-1.
199    o pkg/ggl90:
200      - within IDEMIX add upper limit for horizontal group velocity to
201        avoid instability problems in the explicit horizontal diffusion term for
202        long time steps or high resolution
203    o pkg/diagnostics:
204      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
205        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
206    o testreport:
207      - remove "-v" (verbose option) in default mpirun command.
208    o pkg/seaice/seaice_growth:
209      - catch potential division by zero in ITD code, does not change
210        verification results
211    o pkg/ecco:
212      - retire old codes to the Attic. The calls to retired functions are
213        left in a commented form in case they ever need to be re-activated.
214      - ecco_check.F: issue warning if any old CPP option is
215        defined that corresponds to retired codes -- then stop.
216    o pkg/atm_compon_interf:
217      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
218        coupler: use last time-step value instead of average over cplSendFrq_iter
219        time-step, similar to what is done for seaIceMass.
220        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
221    o eesupp & genmake2:
222      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
223        <= remove until a fix is found for some ifort version on ia32 machine.
224    o pkg/seaice/seaice_evp:
225      - refine residual computation
226    
227    checkpoint65q (2015/11/18)
228    o pkg/seaice/seaice_evp:
229      - fix residual computations so that they no longer affect the actual
230        simulation code
231      - fix seaice_readparams to be able to actually set new parameters
232        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
233    o model/src:
234      - fix wrong truncation (single prec) from "FLOAT" function in expressions
235        like: deltaT*FLOAT(myIter) when myIter is large:
236         a) replaced by DFLOAT (if not seen by TAF);
237         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
238    o pkg/aim_v23:
239      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
240        when pickupSuff is set ; do write rolling pickups + at the end of the run.
241    o pkg/atm_ocn_coupler + ocn_compon_interf:
242      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
243        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
244        add corresponding call in DO_OCEANIC_PHYS.
245    o coupler pkgs:
246      Start a new way to set-up optionally-exchanged variables (previously, only
247       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
248       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
249       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
250       compononent param default can be set accordingly).
251      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
252       but rather applies to a group a fields (going both ways like for DIC)
253       and corresponds to an option of coupling config.
254      coupler (pkg/atm_ocn_coupler):
255      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
256        and read namelist directly (without eessup S/R calls) instead of
257        in the very un-flexible old way, 1 param per line, in fixed order;
258      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
259        cleanly in CPL_CHECK_CPLCONFIG
260      - add new coupling-exchange selectors (some not yet active) including
261        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
262                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
263      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
264        component ; called directly from coupler.F, after comp. registrations;
265      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
266         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
267          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
268      components (pkg/atm_ & ocn_compon_interf):
269      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
270        CPP header file in all pkg source files.
271      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
272        ATM/OCN_CHECK_CPLCONFIG;
273      - add error-counter to track errors (e.g., in "data.cpl") and to stop
274        cleanly in ATM/OCN_CHECK_CPLCONFIG;
275      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
276        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
277        before PACKAGES_READPARMS;
278      verification/cpl_aim+ocn/:
279      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
280        "data.cpl" for coupler (in input_cpl).
281    o eesupp/inc:
282      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
283        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
284        to always cumulate tile local-sum in the same order (still uses
285        MPI_Allreduce like standard code).
286      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
287        that are now identical to standard version (in eesupp/inc).
288    o pkg/shelfice:
289      - add SHELFICETransCoeffTFile for initializing spatially varying
290        heat and salt transfer coefficients
291    o pkg/atm_compon_interf & ocn_compon_interf:
292      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
293        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
294      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
295    o pkg/atm_ocn_coupler:
296      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
297    o pkg/rbcs:
298      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
299        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
300      - add a short report (to STDOUT) about RBCS-mask settings.
301    
302    checkpoint65p (2015/10/23)
303    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
304        there is no adjoint test for EVP, we don't know what it does to the adjoint
305        solution, but at least there are no more recomputation warnings left
306    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
307        a chance of giving the same results as a fully converged VP (JFNK) solver
308    o tools/adjoint_options/adjoint_diva:
309      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
310    o pkg/streamice:
311      - spotted bug in streamice_driving_stress using dyG where should have been dxG
312    o pkg/exf:
313      - remove STOP statement that prevented to use wind or (wind-)stress
314        interpolation for constant-in-time forcing fields (wind/stress period = 0).
315    o pkg/seaice:
316      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
317        5 additionals 2D fields and 6 new store directives
318      - change logic in seaice_readparms.F: EVP code can now be turned on in
319        various ways, setting SEAICE_deltaTev is no longer required,
320        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
321        or SEAICEaEVPcoeff
322    o pkg/shelfice/shelfice_thermodynamics.F
323      - redefining uLoc/vLoc to u/v, instead of 2u/v
324    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
325      - this is an intermediate state of a truely converging EVP that has
326        the potential of outperforming implicit VP methods, I do not recommend
327        using it yet.
328      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
329        and all parameters are hardwired
330      - for convergence it still requires very smooth regularisations, that means,
331        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
332        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
333        specific averaging appears to be required, still subject to tuning
334      - still needs cleaning and I need to turn parameter into runtime parameters
335      - add code to compute and print residuals of iteration, compile with
336        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
337    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
338      that entered with r1.54 on Sep04, 2015, -> update results
339    
340    checkpoint65o (2015/09/14)
341    o pkg/mom_vecinv & mom_common:
342      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
343        called from there.
344      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
345        allows to use Vector-Invariant form in deep atmos and anelastic formulation
346    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
347      and Koenig-Beatty+Holland (2012)
348      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
349      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
350      - requires an extra input argument for S/R seaice_calc_viscosities
351      - tensileStrength's depth dependence is different from Itkin et al. (2015)
352        (to be changed and played with, for now exponential)
353    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
354      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
355        by AREA according to Connelly et al. (2004), JPO.
356      - For EVP and the LSR solver, the implicit part of the drag term is
357        the only non-zero term in the denominator when there is no ice (which
358        prevented running the model with zero ice-ocean drag). If
359        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
360        (or zero main diagonals BU/BV) which need to be caught. A practical
361        consequence is that for open water, the momentum equation reduce
362        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
363        they happen to be zero, often leading to a non-zero solution over
364        open water.
365    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
366        efficient EVP method.
367      - introduce area-weighted averages for e12 (analogously to
368        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
369        remain, but also changing the order of terms in the previous average
370        changed the results as much) -> update experiment
371      - add SEAICE_DELTA_SMOOTHREG code
372      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
373        TEM-code
374      - adjust loop bounds so that only required fields are computed
375      - add new averaging code for zetaZ/deltaZ (again similar to
376        seaice_calc_viscosities.F), inactive by default for now (will change
377        results again), but will replace old code eventually
378    o eesupp/src:
379      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
380        to always cumulate tile local-sum in the same order
381        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
382        Still uses MPI_Allreduce (like standard code) but on array of tiles
383        and should be faster than GLOBAL_SUM_SEND_RECV code.
384      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
385        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
386      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
387         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
388         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
389         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
390         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
391    
392    checkpoint65n (2015/07/29)
393    o pkg/thsice:
394      - add a warning when used with pkg/aim but without updating SST
395        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
396    o pkg/offline:
397      - change where Offline-Fields are loaded, from load_fields_driver.F to
398        directly within FORWARD_STEP, just after updating iter number and time;
399      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
400        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
401       These changes allow:
402        a) to recover exactly on-line results using deltaToffline=deltaTClock,
403        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
404        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
405        time-step, both with GM & KPP files and with recomputing these fields;
406        b) no needs to switch on staggerTimeStep anymore;
407        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
408      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
409    o pkg/offline:
410      - change (rarely used) offset-iteration parameter to an offset time (in s):
411        can easily recover previous offset-iter effect by setting offset-time
412        (offlineTimeOffset) to offset-iter x deltaToffline;
413      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
414        in KPP as part of surface buoyancy forcing) in offline run.
415      - fix ptracers KPP non-local term in the case where KPP is re-computed.
416    o OpenAD
417      - Adding preliminary ggl90 test to OpenAD verification.
418        Config. with ggl90 currently diverges after 64 time steps
419        so will need more work to become more stable
420      - Adding preliminary kpp test to OpenAD verification.
421        required small tweakes in kpp_routines.F
422      - Merge and update from Krishna Narayanan's contrib area:
423        * Add one variable for preliminary OpenAD DIVA
424        * Add replacement time-stepping for OpenAD DIVA
425        * genmake2 flag -diva (but only for OpenAD; preliminary)
426        * required modifs for OAD_support
427        successful preliminary test for tutorial_global_oce_biogeo/
428    o pkg/seaice:
429      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
430      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
431        delta with a smooth function in s/r seaice_calc_viscosity
432        (no effect on EVP)
433      - rename local suffix "sqr" into "sq" for more consistent variable names
434    o pkg/seaice:
435        add new parameter SEAICE_deltaMin that is used ***only***
436        for regularizing Delta (and nothing else, like the parameter
437        which is also used for all sorts of things SEAICE_EPS).
438        Defaults to SEAICE_EPS for backward compatibility only.
439    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
440        the wrong key by inialising it before use -> fixes a recomputation
441        problem but does not fix the gradient
442    o pkg/layers:
443      - move resetting of flux arrays to outside the iLa loop
444        (this caused layers_diapycnal to not work with more than one layer coord.)
445      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
446    o pkg/layers:
447      - remove from common block 3D layers fields (used to diagnose transport
448        in tracer coords) and declare them as local arrays in layers_calc.F
449    o pkg/seaice:
450      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
451        in lab_sea forward experiment (changes results -> updated)
452      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
453    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
454       computations; for SEAICE_VECTORIZE_LSR
455      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
456        sweep to the outside,
457      - remove store directives and add "CADJ loop sequential" directives
458        in analogy to model/src/solve_tridiagonal.F
459      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
460        boundaries to yield more readable code. This has also the charming side
461        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
462        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
463        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
464        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
465        an additional option)
466       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
467       but the adjoint gradients (which are affected by this change) still explode.
468    o coupler (atm & ocn _compon_interf):
469      - avoid using Exch2 IO mapping if not suitable.
470    
471    checkpoint65m (2015/06/15)
472    o pkg/layers:
473      - clean-up old parameters setting (from Sep 2012):
474        + remove old parameters setting from common block (declared locally);
475        + stop if any old parameter is mixed with new parameters;
476        + check for valid or consistent parameter setting (e.g., layers_name)
477      - check that layers_bounds for Pot.Density are in the right range;
478        this is supposed to catch un-updated setting after recently shifting
479        potential density field "prho" by -1000 (now in "sigma" scale).
480    o pkg/layers:
481      - Added missing call to layers_fill for keeping track of tottend in
482        pkg/diagnostics/diagnostics_fill_state.F
483    o pkg/layers:
484      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
485        of diapycnal fluxes
486    o pkg/layers:
487      - reverted changes to interpolation to previous treatment; there
488        was never actually a problem
489    o pkg/layers:
490      - fix interpolation of layers tracers in the presence of partial cells
491      - add lots of new functionality to compute water mass transformation
492        (enabled by CPP flag LAYERS_THERMODYNAMICS)
493      - add new calls from main code (diags_oceanic_surf_flux.F,
494        thermodynamics.F, impldiff.F) and gad to save the necessary fields
495        for layers_thermodynamics calculations
496    o pkg/ptracers:
497      - add capability of stepping a passive tracer forward without advection
498        by setting PTRACERS_advScheme to 0.
499    o pkg/diagnostics:
500      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
501    o pkg/layers:
502      - shift potential density field "prho" by -1000 for density layer averaging so
503        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
504        Note that density bin boundaries (layers_bounds in data.layers) have
505        to be set accordingly (i.e., shifted, in sigma scale).
506    o pkg/layers:
507      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
508      - fix calculation of layer non-weighted velocity and layer probability
509      - add diagnostics for pot.density used for layer averaging
510    o pkg/seaice:
511      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
512        positiveness, modify a few comments and improve variable names,
513      - the changed computation of deltaC affects most seaice-related
514        experiments at the truncation level.
515        seaice_itd.thermo is affected by far the most, with
516        only 7 digits of agreement remaining; update experiments.
517    
518    checkpoint65l (2015/05/04)
519    o pkg/shelfice:
520      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
521        factor drKp1 to zero where it is negative (ie. do not use
522        SHELFICEBoundaryLayer if hFacC>1)
523      - the same for factor drLoc in shelfice_forcing.F
524    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
525        with modules in ptracers, when using testreport option "-small_f"
526    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
527      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
528    o verification/testreport
529      - add new option -small_f
530        with this option testreport first makes the target small_f (*.f files)
531        before running make (all). This is useful for explicit inlining when
532        all sources need to be full available.
533    o pkg/exf/exf_interp.F:
534        remove previous changes related to reverse (decreasing) input grids latitude
535    
536    checkpoint65k (2015/04/01)
537    o pkg/ecco:
538        fix missing cosphi initialization; use eccoiter in place of optimcycle;
539        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
540        instead of active read/write
541    o pkg/ctrl:
542        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
543        instead of active read/write.
544    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
545        return if .NOT.useAUTODIFF
546    o pkg/seaice: add CPP brackets (cost function related).
547    o model/src:
548        add useAUTODIFF run time switch.
549    o pkg/exf/exf_interp.F:
550        add code to allow input grids with latitude starting in the north (i.e. when
551        j=1 corresponds to northern edge of field); modify global_with_exf to test
552        this feature.
553    o verification/testreport:
554      - replace "grep -A3" with POSIX conformal sed command, because there are
555        implementations of grep that cannot do contextual searches
556      - replace "cat -n" by "nl" (two occurrences), because not all implementations
557        of "cat" have the option "-n"
558    o model/src:
559        add new file gsw_teos10.F that contains 3 functions, more or less a copy
560        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
561        convert from conservative to potential temperature. For now they are not
562        called anywhere.
563    o pkg/ggl90: make "useIDEMIX" useful
564      - re-organize code in s/r ggl90_calc a little to move computations that
565        are different for idemix into separate loops (changes verification
566        experiment idemix at truncation level, 12 digits remain -> updated)
567      - requires 2 new 2D fields KappaM, verticalShear
568      - make hFacI and recip_hFacI local 3D variables that are passed to
569        s/r ggl90_idemix
570      - fix and improve some comments
571    
572    checkpoint65j (2015/02/25)
573    o pkg/openad
574      - synchronize seawater.F with version in model/src: replace routine
575        body of sw_temp by calling sw_ptmp and fix/add a few comments.
576    o pkg/mnc:
577      - change default value of pickup_read/write_mnc params to FALSE
578        (since few features are missing in reading MNC pickup files).
579    o model/src:
580      - change default (background) vertical diffusivity for salt to be the
581        temperature (background) vertical diffusivity.
582      - change background vertical diffusivity in vertical mixing pkgs ggl90,
583        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
584        This makes ptracers default diffusivity (that uses salt diffKr) more
585        consistent with vertical mixing schemes.
586    o verification/testreport:
587      - fix typo in "-pcls" option ;
588      - put temp files in /tmp (instead of in local dir)
589      - add option "-ncad" to use genmake2 new option "-nocat4ad"
590      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
591    o pkg/ggl90 (idemix code):
592      - apply few fixes ; add some missing "_d 0" ; update output of exp.
593        global_ocean.90x40x15.idemix
594    o OpenAD
595      - enable active file I/O and begin removal of work-around code
596        for OpenAD for handling control variables (memory vs. active files)
597      - new CPP options file OPENAD_OPTIONS.h
598      - revert to genarr2d gradient check for hs94.1x64x5
599      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
600      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
601    o tools/genmake2:
602      - add option for an alternative Makefile (from Martin) where multiple
603        source files are sent to TAF (instead of all in one file).
604    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
605      - code provided by Carsten Eden as an extension of ggl90
606      - so far the code is turned on within ggl90 by setting a CPP-flag at
607        compile time; a runtime flag implementation is not yet complete
608      - tested in new verification experiment global_ocean.90x40x15.idemix
609    o verification:
610      - reduce length of the AD test run by half for experiments
611        global_ocean.cs32x15 (std + thsice) and isomip
612      - enable active file I/O for OpenAD, adjust verifications accordingly
613      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
614    o verification/testreport:
615      - fix two non-POSIX sed statements so that there are no error messages
616        on Mac OS X
617      - replace hostname -s with hostname | sed 's/\..*$//'
618    o model/src/seawater.F:
619      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
620        (following the matlab code), which would have avoided the bug caught
621        by Matt (see below) in the first place
622    o pkg/shelfice:
623      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
624        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
625      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
626        ice-shelf case (i.e., within surface level).
627      - add config summary in shelfice_check.F
628      - remove global variable recip_SHELFICElatentHeat and replace by a local
629        variable recip_latentHeat
630      - introduce diagnostics for friction velocity uStar (in case of
631        SHELFICEuseGammaFrict)
632      - change verification experiment isomip.htd:
633        + start from pickup (as input_ad at nIter0=8640)
634        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
635        + test SHELFICEuseGammaFrict = .TRUE.
636        + test SHELFICEadvDiffHeatFlux = .TRUE.
637    o model/src:
638      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
639        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
640        update output of experiments global_with_exf.yearly and isomip (all 6).
641    o pkg/shelfice:
642      - change setting of kTopC to also be zero where there is no ice-shelf.
643      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
644        ice-shelf is.
645      - first attempt to get RealFreshWaterFlux effects: for now, only without
646        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
647    o pkg/seaice: add the option to prescribe a fixed thickness PDF
648      for thermodynamic calculations
649      - because of divisions of the type 7/7 not exactly equal to 1, this change
650        affects results of some verification experiments by up to 4 digits:
651        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
652        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
653        adjoint: lab_sea, lab_sea.noseaicedyn
654        -> updated
655    
656    checkpoint65i (2015/01/23)
657    o model/src:
658      - change units of frictionHeating field from W to W/m^2
659      - fix bug in frictional heating from stratospheric drag in
660        S/R ATM_PHYS_TENDENCY_APPLY_V
661      - with synchronous time-stepping: move resetting to zero of frictionHeating
662        field from load_fields_driver.F to thermodynamics.F ;
663      - add diagnostics for frictional heating.
664    o model/src & gmredi K3D:
665      - add frictionHeating field to pickup-files (for synchronous time-stepping)
666      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
667      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
668        and name in pickup file).
669      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
670    o model/src:
671    - move (from ini_forcing.F) initialisation of all arrays in header file    - move (from ini_forcing.F) initialisation of all arrays in header file
672      FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart      FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
673      (since Nov 2012) with option selectAddFluid=1.      (since Nov 2012) with option selectAddFluid=1.
