4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - move call to CTRL_INIT & CTRL_ADMTLM from the middle to the bottom of
9        packages_init_fixed.F to allow other pkgs to set mask and weight fields.
10    
11    checkpoint66f (2017/04/06)
12    o model/src:
13      - add specific run-time param to select level of printed plot-field-maps,
14        set by default to debugLevel. Remove internal param "printDomain".
15    o pkg/seaice:
16      - add flag to add snow mass to seaiceMassC/U/V, the default is
17        SEAICEaddSnowMass=.FALSE., not to change previous results
18    o pkg/bling
19      - Bug fix in bling_production regarding unit conversion for diagnostics
20        being put in the wrong place
21    o model/src:
22      - add back recomputation of rSurfW & S to ensure consistent column thickness
23        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
24        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
25        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
26    o pkg/autodiff:
27      - clean-up "checkpoint.flow"
28    o pkg/rw (Contribution from Jody Klymak):
29        option to set mds file suffix as function of time in simulation:
30        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
31           to select file suffix format; by default (=0), use iteration number;
32        *) add simple routine to return file suffix according to rwSuffixType;
33        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
34           use new S/R to get file suffix, except for debug output file (diagFreq)
35           and pkgs offline & rbcs input files.
36    o pkg/rw:
37      - uniform processing of "I10" suffix across writing fld routines; used to
38        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
39        (similar to cg3d.F, cg3d_ex0.F)
40    o pkg/mom_vecinv:
41      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
42        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
43    o pkg/bling:
44      - Many small changes intended to clean the code.
45        Unnecessary ADJOINT_SAFEs removed ;
46        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
47        diagnostics added.
48    
49    checkpoint66e (2017/03/14)
50    o pkg/exf:
51      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
52        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
53        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
54        avoid any dynamic allocation ;
55      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
56        read-in ; add warning when file is read-in but not used within pkg/exf ;
57        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
58      - update exf_summary.F (print {FLD}RepCycle).
59    o verification/global_with_exf:
60      - switch on exf interpolation in AD test (just like the forward test)
61    o pkg/mom_vecinv:
62      - add storage directives to avoid recomputations within mom_vecinv.F
63        which were generating seg. fault with gfortran -devel
64    o pkg/ctrl, pkg/smooth:
65      - initialize array halos which were generating seg. fault with
66        gfortran -devel in adjoint mode
67    o pkg/exf:
68      - for each input field, enable to specify a field specific repeat-cycle
69        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
70    o verification/lab_sea:
71      - update AD results of primary test and noseaicedyn test after switching
72        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
73        check stays about the same.
74    o pkg/exf:
75      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
76      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
77    o pkg/bling, USE_EXFCO2 code:
78      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
79      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
80    o pkg/exf:
81      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
82      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
83        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
84        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
85      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
86        EXF_INIT_FLD) and update calls in exf_init_varia.F
87      - For now, for backward compatibility, keep a simplified version of S/Rs
88        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
89      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
90        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
91    o tools/genmake2:
92      - replace "bc -l" (only used once) by "expr" (already used).
93    o verification/global_ocean.cs32x15:
94      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
95        Note: exf setting (data.exf) can be compared to other exf secondary exp
96        "seaice" (kept with useCAL=T) which has same time dependent forcing.
97    
98    checkpoint66d (2017/02/13)
99    o pkg/exf:
100      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
101        early on (in packages_boot.F) to stress this change in pkg setting.
102      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
103    o model/src:
104      - move call to ecco_phys to end of time step; this may induce minor
105        cost function changes by shifting time averages by one time step
106        for some variables; this revision resulted in changed adjoint results
107        in MITgcm_contrib/verification_other/global_oce_cs32
108    o pkg/exf:
109      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
110        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
111        e.g. precip, are not available.
112    o pkg/flt:
113      - flt_init_varia.F: use pickupSuff if specified
114      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
115        intermediate, step towards completing pkg/exch2 support within pkg/flt;
116        ifdef DEVEL_FLT_EXCH2 then:
117        - flt_init_fixed.F: comment out stop
118        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
119        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
120        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
121        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
122    o tools/genmake2 & pkg/pkg_depend:
123      - define new type of pkg dependency rule ("=pkg_x"), less strict than
124        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
125        (-pkg_x in packages.conf).
126      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
127      - add "+cal" to dependency list of pkg/ecco (needed to compile).
128      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
129    o utils/matlab:
130      - adding ocean_basin routines for defining basin masks.
131    o pkg/exf:
132      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
133        arguments, allowing to check (and stop) if parameter setting of
134         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
135        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
136        for backward compatibility.
137      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
138        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
139    o pkg/bling (USE_EXFCO2 code):
140      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
141        by adding a call to S/R EXF_GETFFIELD_START.
142    o pkg/exf:
143      - allows to compile without pkg/cal (but disabled by current dependency
144        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
145        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
146        of {FLD}startdate1 & date2 ; consistency check not yet coded.
147    o verification/global_ocean.cs32x15:
148      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
149        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
150    o pkg/exf:
151      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
152        calculations); change FWD experiment global_ocean.cs32x15
153        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
154    o pkg/exf:
155      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
156         {FIELD}startdate to {FIELD}StartTime
157        Note: new name also fit better the content, i.e, a start time in second.
158    o eesupp/src:
159      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
160    o pkg/exf:
161      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
162        to allow to read-in Sensible & Latent Heat flux ;
163      - simplify pkg/exf main options:
164        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
165           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
166           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
167        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
168           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
169        3) improve options documentation in EXF_OPTIONS.h.
170    o pkg/ecco:
171      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
172        ecco_summary.F: add passive tracer cost functions to gencost;
173        m_ptracer and m_boxmean_ptracer
174    o pkg/ctrl:
175      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
176        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
177        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
178        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
179    o model/src:
180      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
181        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
182    o pkg/exf:
183      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
184        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
185    
186    checkpoint66c (2017/01/19)
187    o verification:
188      - add new option "-src" to testreport to only produce source code (*.f),
189        including taf output src code (if using '-adm'/'-tlm' option).
190    o pkg/exf:
191      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
192    o pkg/diagnostics:
193      - add run-time variable diagMdsDir to specify a subdirectory for
194        diagnostic output when mds is being used and mdsioLocalDir is not.
195    o pkg/mnc:
196      - mnc_utils.F: edit stop message
197    o pkg/autodiff:
198      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
199        add HAVE_SYSTEM bracket around system call to mkdir
200    o pkg/profiles:
201      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
202        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
203      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
204        add HAVE_SYSTEM bracket around system call to mkdir
205    o pkg/smooth:
206      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
207      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
208      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
209    o pkg/exf:
210      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
211        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
212        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
213      - summary: skip detailed field report if not used (empty file-name).
214    o tools/xmakedepend:
215      - In case line editor "ed" is missing, switch to "sed" command to clean-up
216        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
217    o pkg/exf:
218      - change definition of "hflux" input file to always include Short-Wave;
219        this is now consistent with hflux computation (if using bulk-formulae)
220        and hflux diagnostic & documentation (in EXF_FIELDS.h).
221    
222    checkpoint66b (2016/12/01)
223    o model & momentum pkgs:
224      - implement fully implicit bottom friction combined with implicit surf.
225        pressure, for now, only in hydrostic formulation:
226        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
227          and run with selectImplicitDrag=2 ;
228        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
229      - partial implicit time-stepping (bot. friction + vert. visc first, then
230        surf. press) corresponding to selectImplicitDrag=1 should be applicable
231        to NH formulation but not available until we solve for surf. pressure
232        increment (instead of full etaN).
233      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
234        with implicit vertical viscosity.
235    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
236      - this is a first version that includes many regularisations that may
237        not all be necessary, to be sorted out,
238      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
239      - change one verification experiment in seaice_itd to use and test new code
240      - seaice_growth: catch a case where the argument of log can be zero
241        or smaller (important for code stability)
242    o model/src:
243      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
244        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
245        similar A.X'=Y' system (with same matrix A) in subsequent calls;
246        switch based on errCode (In/Out) argument value; in calling routines,
247        initialise errCode before first call.
248    
249    checkpoint66a (2016/10/18)
250    o pkg/bling:
251      - BLING package now loads in atmospheric pCO2 file using exf package routines
252        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
253    o model/src & pkg/ptracers:
254      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
255        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
256        implicitDiffusion (respectively) are used (even without momImplVertAdv
257        or temp,salt,PTRACERS_ImplVertAdv).
258    o model/src & generic_advdiff:
259      - add parenthesis in main diagonal calculation of implicit vertical
260        diffusion matrix (impldiff.F & gad_implicit_r.F).
261        This affects results at machine truncation level; update output of many
262        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
263    o pkg/mom_commom & generic_advdiff:
264      - add deep atmosphere and anelastic scaling factor in implicit vertical
265        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
266    o model/src:
267      - remove few unnecessary temp array copies in solve_tridiagonal.F
268        & solve_pentadiagonal.F
269    
270    checkpoint65z (2016/09/28)
271    o pkg/seaice: fix multithreading for seaice_fgmres.F
272      - remove unecessary variables from common blocks
273      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
274        basis, that are stored in commom blocks (including integer variable i1)
275      - clean up code a little by removing commented lines that refer to
276        original code
277      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
278    o MITgcm manual:
279      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
280        preliminary documentation for generic controls (8.3; ctrl.tex),
281        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
282        ecco_costfunction.tex
283    o pkg/ecco:
284      - update and cleanup list of CCP options
285      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
286        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
287      - add checks that retired run-time options are not used, and in relation
288        to gencost_mask and gencost_errfile
289      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
290        gencost_nrecperiod
291      - fix m_eta computation for virtual salt flux case
292      - add m_horflux_vol case (selected via gencost_barfile) that computes
293        transports via cost_gencost_boxmean (gencost_flag=-3)
294      - use gencost_flag more systematically (i.e., avoid using gencost_name)
295        for code switches (aside from physical variable selection)
296    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
297      attempt appears to be a bit of a hack and my need some repair down the road
298    o pkg/exf:
299      - interpolation near South Pole: fix criteria on input field latitude.
300    o pkg/icefront & pkg/exf:
301      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
302        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
303    o pkg/exf:
304      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
305        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
306        (add suffix "_out" instead of a prefix); keep same record number as in
307        input file but always write record 1 first (to avoid a STOP in I/O S/R).
308        Change output file content by writing interpolated field before applying
309        land-sea mask (helpful for debug).
310      - 2 compon. vector interpolation with rotation: apply scaling factor on
311        each compon. (Eastward and Northward) just before rotation.
312    o pkg/bling:
313      - Cleaned package. Removed not needed code and comments.
314      - adjoint example now works
315        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
316    o pkg/ptracers:
317      - add Bruno Deremble's code to complete the linear surface correction
318        for tracer conservation;
319      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
320    
321    checkpoint65y (2016/07/29)
322    o pkg/debug (stats):
323      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
324        proc/thread mapping);
325      - fix Min & Max for case where 1 thread has only empty tiles;
326      - use RL variable to count number of wet grid points (with big domain,
327        can be too large to fit into integer*4).
328    o pkg/monitor:
329      - use RL variable to count number of wet grid points (but used only for del2)
330      - add new routine to compute Advective CFL within tracer time-stepping with
331        writing delayed until next monitor output.
332    o pkg/obcs:
333      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
334    o pkg/cal:
335      - calandar-dump: treat case myTime < timePhase in the same way as in
336        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
337    o pkg/dic & seaice:
338      - fix compilation of ocean component for coupled atm+ocn model with
339        seaice dynamics & dic.
340    
341    checkpoint65x (2016/06/11)
342    o add a license text file in main MITgcm tree.
343    o added pkg/bling:
344      - intermediate complexity biogeochemical model
345      - see bling_description.txt for details
346      - verification experiment is global_oce_biogeo_bling (for now, in
347        Contrib/verification_other/); tested daily on baudelaire with gfortran.
348      - add entry point in pkg/gchem for new pkg "bling".
349    o pkg/seaice: fix tensile stength computation
350      - replace global field tensileStrength by tensileStrFac
351      - tensileStrFac can be computed once in S/R seaice_init_varia
352      - fortunately that does not affect any verification results
353    
354    checkpoint65w (2016/05/12)
355    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
356         with ECCO_CTRL_DEPRECATED defined
357    o verification/global_ocean.cs32x15:
358      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
359        with "selectNHfreeSurf=1".
360    o model/src (non-hydrostatic free-surface):
361      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
362        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
363      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
364        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
365        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
366        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
367      - Update output (changes at machine truncation level) of verification exp:
368        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
369        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
370    o pkg/seaice: ITD code
371      - fix picking up from a single category model by initialising
372        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
373      - split a long warning message in seaice_check_pickup.F into two lines,
374        because NEC SX-ACE cannot deal with the long line.
375    o model/src:
376      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
377    o pkg/seaice:
378      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
379    o pkg/seaice:
380      - add basal stress as parameterisation for grounding ice
381        following Lemieux et al. (2015)
382      - turn on by setting new parameter SEAICEbasalDragK2 to a value
383        larger than 0. Lemieux et al. (2015) recommend 15.
384      - The adjoint complains with extra recomputations so there is also a
385        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
386        order to postpone the problem
387      - compile the new code in lab_sea
388    o verification/halfpipe_streamice:
389      - update both TAF and OpenAD adm output (machine truncation differences)
390    
391    checkpoint65v (2016/04/08)
392    o verification/advect_xz:
393      - increase overlap size from 3 to 4 and add new secondary test for PQM
394        advection scheme (with mono & wino limiter).
395      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
396    o model/src:
397      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
398        added phi0Ref) to set vertical axis origin and phiRef origin;
399        keep Ro_SeaLevel for backward compatibility (with a warning).
400       According to coordinate and fluid type:
401        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
402        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
403        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
404        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
405      - remove Ro_SeaLevel from ATM experiment parameter files;
406      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
407        complement; update output.txt (changes at machine truncation level).
408    o pkg/seaice/seaice_evp.F
409      - simplify computation of deltaZ and zetaZ to simple averaging following
410        Bouillon et al. (2013). This removes a lot of code, but also changes
411        verification experiment lab_sea.hb87 -> updated
412    
413    checkpoint65u (2016/03/14)
414    o pkg/generic_advdiff:
415      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
416        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
417        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
418        testing and not for actual use.
419    o model/src:
420      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
421        origin r = rF(1);
422      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
423        in EOS for height coordinate: enable to include NH Pressure or to use
424        more accurate pressure vertical profile; options not linked to EOS type
425        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
426      - start to implement variable gravity (along vertical): for now, only with
427        z-coords (not even z*).
428      - add Ideal Gas equation of state for height coordinate.
429      - update OpenAD output (affected at machine truncation level) of exp:
430        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
431    o pkg/exf:
432      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
433        of exf interpolation (before any rescaling, rotation or interpolation
434        to velocity point) for each field that gets loaded from file. This option
435        identically mimics the input file organization (e.g. record numbers in year
436        by year input files) besides the change in horizontal grid.
437      - add rotateStressOnAgrid run-time switch so that wind stress fields
438        can be provided on the A-grid in zonal/meridional direction and
439        rotated on the fly. This only applies to the case when the exf
440        interpolation is off and rotateStressOnAgrid is false by default.
441    o model/src:
442      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
443        it's also used with pkg/atm_phys) and add few more parameters (but still
444        inactive, src code yet to come)
445    
446    checkpoint65t (2016/02/10)
447    o pkg/atm_phys:
448      - from Ruth Geen: add optical depth dependence on CO2 concentration.
449    o model/src:
450      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
451        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
452        Update output of exp. deep_anelastic (changes at truncation level).
453    o tools:
454      - add a hack in "remove_comments_sed" (used only with TAF) for recent
455        version of OpenMPI (shipped with FC.23): comment out the new header
456        file "mpif-sizeof.h" which causes problems to TAF.
457    o pkg/seaice:
458      - change the termination criterion so that maxits (SEAICElinearIterMax)
459        has an effect
460      - unify iteration parameters for implicit solvers (JFNK and Picard)
461        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
462        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
463        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
464        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
465        SEAICEnonLinTol     replaces JFNKgamma_nonlin
466      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
467      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
468        use with SEAICEuseKrylov
469    o pkg/seaice/seaice_lsr.F
470        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
471        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
472        an effect.
473    o pkg/seaice: add two new parameters
474      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
475        parameter is not in any namelist)
476      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
477        a preconditioner for the non-linear Newton iteration of the JFNK
478        solver
479    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
480      affects some experiments at truncation level:
481      - global_ocean.cs32x15.icedyn (11 digits),
482      - global_ocean.cs32x15.seaice (11 digits),
483      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
484      - also update global_ocean.cs32x15 adjoint and tangent-linear results
485    o pkg/salt_plume & pkg/thsice:
486      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
487        connect salt_plume flux to ATM-OCN coupling pkgs interface:
488       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
489         export to coupler interface) even without compiling pkg/salt_plume ;
490       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
491         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
492    o pkg/dic:
493      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
494        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
495        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
496      - move also update with values from ATM-OCN Coupler in the same new S/R
497        (previously done in ocn_apply_import.F).
498    o tools/adjoint_options:
499      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
500        has been changed on Jan 14, 2016.
501    o pkg/ggl90:
502      - add alternative discretisation of vertical shear (off by default), to
503        compute the mean (@ grid-cell center) of vertical shear compon instead of
504        vertical shear of mean flow (@ grid-cell center).
505      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
506        results on adjacent faces of cubed-sphere grids; this fix the restart.
507    o pkg/atm_compon_interf:
508      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
509        pass last value, stored directly before export to CPL ;
510        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
511      - remove atmSLPr from pickup files (no longer needed for restart)
512    
513    checkpoint65s (2016/01/13)
514    o eesupp & genmake2:
515       - first check for Function ETIME and, if it fails, then check for subroutine
516         ETIME and consistent output; use the appropriate version in timers.F
517    o model/src:
518      - to check restart test, add option to apply EXCH to U,V earlier, just before
519        integr_continuity; turned off by default.
520    o pkg/dic:
521      - remove CPP option USE_ATMOSCO2 (not needed)
522    o tools/tst_2+2:
523      - try to ignore difference between +0 and -0 in binary file, causing test
524        to fail for no good reason.
525    o eesupp & genmake2:
526      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
527        but also check (in genmake2) that test runs and returns meaningful results.
528    o coupler pkgs:
529      Finish implementation of optionally-exchanged variable switches (started on
530       Nov 12) with addition of few more exchanged fields, including 2-way exchange
531       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
532       advection in OCN component; this requires sequential coupling.
533      coupler (pkg/atm_ocn_coupler):
534      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
535        routines (useful for debug).
536      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
537         flux, DIC fields) if corresponding switch is ON.
538      - add option to export RunOff to OCN (to use for DIC river input)
539      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
540      components (pkg/atm_ & ocn_compon_interf):
541      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
542        optionally exchanged fields; add a check & stop in cpl_readparms.F.
543        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
544        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
545      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
546        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
547      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
548      - hold in common block coupler optionally-exchanged variable switch
549        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
550      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
551        this is intended to replace the OCN cplFldtave.* output files (not updated
552        to contain new additional exchanged fields).
553    o pkg/dic:
554      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
555    o pkg/thsice:
556      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
557        and writing of thsice pickup files.
558    o pkg/atm_compon_interf:
559      - move all field individual export-call out of cpl_export_import_data.F
560        into new S/R ATM_EXPORT_FIELDS
561    o pkg/atm_compon_interf:
562      - store state variables (for now, only thSIce fields) just before beeing
563        exported (in cpl_export_import_data.F, like on ocean side) instead of from
564        atm_store_my_data.F like all exported fluxes.
565      - new version of pickup_cpl: write field names into meta file and read meta
566        file to find field postion in pickup. Also only write/read fields meeded for
567        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
568    o pkg/dic:
569      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
570    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
571        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
572        value can be from domain [0,1] to average between the two methods
573    o pkg/atm_phys:
574      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
575        hold fixed in time).
576    
577    checkpoint65r (2015/12/21)
578    o pkg/seaice:
579        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
580        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
581    o pkg/seaice:
582      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
583        when SEAICEscaleSurfStress=.TRUE.,
584      - apply areaW and areaS in S/R seaice_calc_lhs
585    o pkg/atm_phys:
586      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
587        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
588        for individual contribution (convection, LSC cond, radiation)
589      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
590        information); activated with: solar_exponent=0. and wv_exponent=-1.
591    o pkg/ggl90:
592      - within IDEMIX add upper limit for horizontal group velocity to
593        avoid instability problems in the explicit horizontal diffusion term for
594        long time steps or high resolution
595    o pkg/diagnostics:
596      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
597        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
598    o testreport:
599      - remove "-v" (verbose option) in default mpirun command.
600    o pkg/seaice/seaice_growth:
601      - catch potential division by zero in ITD code, does not change
602        verification results
603    o pkg/ecco:
604      - retire old codes to the Attic. The calls to retired functions are
605        left in a commented form in case they ever need to be re-activated.
606      - ecco_check.F: issue warning if any old CPP option is
607        defined that corresponds to retired codes -- then stop.
608    o pkg/atm_compon_interf:
609      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
610        coupler: use last time-step value instead of average over cplSendFrq_iter
611        time-step, similar to what is done for seaIceMass.
612        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
613    o eesupp & genmake2:
614      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
615        <= remove until a fix is found for some ifort version on ia32 machine.
616    o pkg/seaice/seaice_evp:
617      - refine residual computation
618    
619    checkpoint65q (2015/11/18)
620    o pkg/seaice/seaice_evp:
621      - fix residual computations so that they no longer affect the actual
622        simulation code
623      - fix seaice_readparams to be able to actually set new parameters
624        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
625    o model/src:
626      - fix wrong truncation (single prec) from "FLOAT" function in expressions
627        like: deltaT*FLOAT(myIter) when myIter is large:
628         a) replaced by DFLOAT (if not seen by TAF);
629         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
630    o pkg/aim_v23:
631      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
632        when pickupSuff is set ; do write rolling pickups + at the end of the run.
633    o pkg/atm_ocn_coupler + ocn_compon_interf:
634      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
635        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
636        add corresponding call in DO_OCEANIC_PHYS.
637    o coupler pkgs:
638      Start a new way to set-up optionally-exchanged variables (previously, only
639       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
640       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
641       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
642       compononent param default can be set accordingly).
643      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
644       but rather applies to a group a fields (going both ways like for DIC)
645       and corresponds to an option of coupling config.
646      coupler (pkg/atm_ocn_coupler):
647      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
648        and read namelist directly (without eessup S/R calls) instead of
649        in the very un-flexible old way, 1 param per line, in fixed order;
650      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
651        cleanly in CPL_CHECK_CPLCONFIG
652      - add new coupling-exchange selectors (some not yet active) including
653        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
654                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
655      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
656        component ; called directly from coupler.F, after comp. registrations;
657      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
658         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
659          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
660      components (pkg/atm_ & ocn_compon_interf):
661      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
662        CPP header file in all pkg source files.
663      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
664        ATM/OCN_CHECK_CPLCONFIG;
665      - add error-counter to track errors (e.g., in "data.cpl") and to stop
666        cleanly in ATM/OCN_CHECK_CPLCONFIG;
667      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
668        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
669        before PACKAGES_READPARMS;
670      verification/cpl_aim+ocn/:
671      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
672        "data.cpl" for coupler (in input_cpl).
673    o eesupp/inc:
674      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
675        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
676        to always cumulate tile local-sum in the same order (still uses
677        MPI_Allreduce like standard code).
678      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
679        that are now identical to standard version (in eesupp/inc).
680    o pkg/shelfice:
681      - add SHELFICETransCoeffTFile for initializing spatially varying
682        heat and salt transfer coefficients
683    o pkg/atm_compon_interf & ocn_compon_interf:
684      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
685        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
686      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
687    o pkg/atm_ocn_coupler:
688      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
689    o pkg/rbcs:
690      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
691        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
692      - add a short report (to STDOUT) about RBCS-mask settings.

694    checkpoint65p (2015/10/23)
695    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
696        there is no adjoint test for EVP, we don't know what it does to the adjoint
697        solution, but at least there are no more recomputation warnings left
698    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
699        a chance of giving the same results as a fully converged VP (JFNK) solver
700    o tools/adjoint_options/adjoint_diva:
701      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
702    o pkg/streamice:
703      - spotted bug in streamice_driving_stress using dyG where should have been dxG
704    o pkg/exf:
705      - remove STOP statement that prevented to use wind or (wind-)stress
706        interpolation for constant-in-time forcing fields (wind/stress period = 0).
707    o pkg/seaice:
708      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
709        5 additionals 2D fields and 6 new store directives
710      - change logic in seaice_readparms.F: EVP code can now be turned on in
711        various ways, setting SEAICE_deltaTev is no longer required,
712        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
713        or SEAICEaEVPcoeff
714    o pkg/shelfice/shelfice_thermodynamics.F
715      - redefining uLoc/vLoc to u/v, instead of 2u/v
716  o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz  o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
