5      ==============================      ==============================
6    
7    checkpoint59d
8    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
9     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
10     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
11    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
12     and change default value of parameter "GM_Small_Number";
13     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
14       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
15       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
16    o pkg/ecco: cost function when applying pkg/smooth to controls
17    o pkg/ctrl: add forcingPrecond run time parameter
18    o pkg/seaice:
19     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
20     - fix bug in metric terms of u-equation in LSR solver (implicit part),
21       changes verification/lab_sea
22     - rearrange implicit part of u-equation in LSR solver to make it easier to
23       read, understand, and debug. This causes changes at the truncation level.
24     - fix (serious) bug in the boundary conditions (sign error in the implicit
25       part) of the LSR solver. Changes all LSR results.
26     - fixed problem with HSNOW initialization to avoid thick snow when AREA
27       is initilized with small values - does not change lab_sea results.
28     - added HsnowFile initialization capability
29    o pkg/smooth: addition to model/src and pkg/ctrl so allow
30     initialization of pkg/smooth and application to control vector
31    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
32    o dependencies: pkg/profiles requires pkg/cal
33    o pkg/profiles:
34     - added option ALLOW_PROFILES_GENERICGRID
35         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
36         that interpolation information (grid points and coefficients) is provided
37         within the netcdf input files.
38         -> sample matlab scripts can be found in MITgcm_contrib/gael
39         that allow you to prepare netcdf input files.
40     - also modified: cleaner include statements, cleaner error print statements,
41       cleaner stops when error, and more tests of the netcdf input files consistency.
42    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
43    o pkg/seaice:
44     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
45       requires a new routine: seaice_diagnostics_fill.F
46     - make sure that seaice does not move if not forced (pressure replacement
47       method, Hibler and Ip, 1995), changes results
48     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
49     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
50       It is turned off by default (=-1.), because it changes the results.
51     - make it possible to read AREA from a file, too.
52    
53    checkpoint59c
54    o add S/R and diagnostics for oceanic mixed-layer depth
55    o move GMRedi call after all vertical mixing schemes (including KPP)
56    o pkg/thsice:
57     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
58      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
59    o pkg/obcs:
60     - bug fix for balance code
61    o pkg/seaice:
62      - allow values of SEAICE_elasticParm > 1
63      - add new parameter SEAICE_evpTauRelax as an alternative
64        to SEAICE_elasticParm
65      - make lsr boundary conditions free slip (by default), changes result
66      - add code for no slip boundary conditions for lsr
67      - set minimum of zeta to zero (and not 4e8) (changes results)
68      - add a cap on AREA after advecting AREA if seaice_growth is not called
69    o change calculation of Visbeck K:
70      - no longer depend on tapering scheme; instead, compute slope (limited
71        by GM_maxSlope). this is equivalent to what was comuted before with
72        clipping or linear tappering.
73      - fix vertical averaging (wrong by 1/2 level)
74      - leave the old version (but will not be maintained) within
75        #ifdef OLD_VISBECK_CALC / #endif
76      - update output of exp. ideal_2D_oce
77    o change error catch in calc_r_star to improve vectorization
78    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
79      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
80    o adjoint:
81      Re-organized adjoint checkpointing according to Matt Mazloff
82      (but with modifs/completions/cleanups)
83      Storing is now bundled into large arrays to optimized I/O
84      (and second step in cleanup of the_main_loop)
85    
86    checkpoint59b
87    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
88      - export/import (between ocean & coupler) fields needed for ocean DIC.
89    o pkg/seaice:
90      - get rid of three more exchanges seaice_calc_viscosities (required
91        different loop boundaries in seaice_lsr and seaice_ocean_stress)
92      - bug fix in seaice_ocean_stress (update of lab_sea required)
93      - reduce loop boundaries to necessary minimum also in seaice_evp
94      - go back to the old way of computing deltaC/Z as the adjoint likes that
95        better
96    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
97      passive tracer to an Age Tracer) + update output.txt
98    o pkg/exf:
99      - implement A-grid / C-grid selection for wind-stress input files.
100      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
101      for now, in exf_bulk_largeyeager04.F only :
102      - change implementation for case where windspeed + 2. components wind-stress
103        are read-in. AND use rhoConstFresh to convert evap.
104    o pkg/seaice:
105      - use correct EXCH_UV for wind-forcing (on A-grid).
106      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
107        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
108    o pkg/exf:
109      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
110      EXF_INTERPOLATION:
111      - merge global_with_exf/code version of exf_interp_read.F
112        to the main code ;
113      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
114        reading the file ; Important: This options needs to be defined to recover
115        previous code.
116        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
117      - no longer loose real*8 precision along the way when using exf_iprec=64.
118    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
119      - change discretisation of evp-solver in order to avoid another exchange
120        (changes lab_sea) and clean up a little
121      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
122        help the adjoint (this also changes the results slightly)
123      - add a few "_d 0" where they had been missing in seaice_evp.F
124      - cleaning up: remove unused seaice_calc_rhs.F
125    o pkg/exf: some cleaning-up:
126      - change various "constants" into runtime parameters
127      - cleaned-up Large&Yeager04 routine which should eventually
128        replace exf_bulkformulae.F (changed names of S/R and CPP)
129        and merged various ALLOW_ATM_WIND options
130     only used with thsice pkg (in thsice_get_exf.F):
131      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
132        which are used when useStabilityFct_overIce=TRUE (= the default)
133      - change default values of ice & snow emissivity and scale downward LW
134        by ice & snow emissivity.
135    o pkg/thsice:
136     fix few little problems, in thsice_calc_thickn.F:
137      - growth vertically (and not laterally) if iceFrac == iceMaskMax
138      - melt only laterally if hIce < hThinIce (as the comments say)
139      and in thsice_extend.F:
140      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
141      - start to form ice as soon as the minimum ice-volume is reachable.
142     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
143      and cpl_aim+ocn
144    o pkg/kpp
145     - move computation of surface related input fields to KPP into a new
146       subroutine kpp_forcing_surf.F
147     - remove wrong (within bi,bj loops) EXCH calls.
148     - little cleaning (add argument myThid in last position, cvs header ...)
149     - for now, fix conservation problem by exchanging KPPviscAz (may not
150       be the best fix)
151    o pkg/seaice
152     - check for inconsistent evp parameter/cpp-flag combination
153     - remove leftover errIO flat for obsolete name list error handling
154    o OpenAD
155     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
156    
157    checkpoint59a
158    o pkg/seaice: some parameter clarifications and a little bit of clean up
159    o pkg/thsice: rename run-time parameters:
160       himin       -> hIceMin
161       himin0      -> hThinIce
162       hihig       -> hThickIce
163       i0          -> i0swFrac
164       transCoef   -> bMeltCoef
165       frac_energy -> fracMelting
166      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
167       with default values (for now) that do not change the results.
168      remove old version of thsice vars advection in pkg/seaice.
169    o in FFIELDS.h:
170      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
171      - make pLoad & sIceLoad always available (but still only used if
172         ATMOSPHERIC_LOADING is #define).
173    o pkg/kpp: replaced _KPP_RL with _RL
174    o bug fixes for vertical diffusivity computations when both KPP and
175        3D diffusivity arrays are used.
176    o pkg/seaice: fix bug in evp solver, while doing that
177      - change (improve?) discretization of stress computations for both
178        cgrid-lsr and evp solver
179      - add a new routine to compute strain rates
180      - the above changes lab_sea results
181      - add no slip conditions for evp solver (off by default), lsr-version
182        may follow
183      - fix exchange for shear at Z-points (does not change lab_sea)
184      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
185        (to force the user to pick a time step since there is not "safe" way
186        of choosing it)
187      - add principal stress diagnostics
188      - rearrange fields for evp a little to avoid having to call a: too many
189        exchanges and b: exchanges for stress trensor components which we do
190        not have.
191      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
192        of evp, complete rewrite for lsr case (latter is does not yet work
193        in all cases)
194    o pkg/kpp: add code to have mixing in shelf ice caverns
195      - add myThid to all kpp routines (long overdue)
196    
197    checkpoint59
198    o pkg/exf:
199      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
200        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
201      - move exf header files from lower_case.h to UPPER_CASE.h ;
202        add missing cvs Header & Name
203      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
204      - add namelist param. selectStressGridPosition, exf_monFreq
205      - retire many _CLIM routines, and remove data.exf_clim
206        + params moved to data.exf
207        + climsst, climsss now handled by exf_set_gen, i.e.
208          climss?period=0 refers to constant field,
209          climss?period=-12 to monthly forcing
210      - split up namelists in data.exf
211    o pkg/seaice:
212      - remove seaice_exch and seaice_exch_uv
213      - remove superfluous exchange of theta
214      - add myThid to seaice_budget_ocean/ice
215      - add new interface for atmospheric wind forcing (C-grid only)
216        + new routine
217        + two new field (taux, tauy for stress over ice)
218        + removed one global field (DAIRN) for C-grid case only
219    o pkg/thsise
220      - 2nd set of modifs for thsice adjoint in conjunction with exf
221    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
222    
223    checkpoint58y_post
224    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
225      vertical diffusivity, similar to that in MOM4; turned on using
226      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
227      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
228    o Added capability for 3D specification of background vertical diffusion
229      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
230      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
231      "data" file that contains the 3D vertical diffusivity coefficients.
232    o ice dynamics (pkg/seaice) with thsice thermodynamics:
233      - add code within pkg thsice to advect & diffuse sea-ice fields
234      similar to (and will replace) what has been added in  seaice_advdiff.F,
235      but: - conserving Mass, Heat & Salt.
236           - better when using non-linear advection scheme (not yet fully tested)
237           - can also be used in atmospheric set-up (for now, only the diffusion).
238    
239    checkpoint58x_post
240    o IO option for global-file compact format:
241      - add options when generating topology (utils/exch2/matlab-topology-generator)
242      - add I/O capability (pkg/mdsio).
243      - adapt utils/matlab/rdmds.m to read this format.
244      for now long-line format not yet supported by pkg/mdsio (& exch2).
245    o shelfice: add a few diagnostics
246    
247    checkpoint58w_post
248    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
249      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
250      (and replace horiVertRatio in NH code).
251      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
252                         and tutorial_plume_on_slope (sensitive to truncation)
253    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
254      directly to drive seaice model (C-grid only)
255    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
256     - reintroduce computation of wind from stress,
257     - compute tau (in exf_bulkformulae.F) from windstress averaged to
258       mass points to avoid tau = 0
259     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
260    o rdmnc.m: make it work with "global" files created with gluemnc
261    o rdmnc.m : some improvements in dealing with singleton dimension
262      (tested on all testreport mnc output files).
263    o genmake2: disable pkg/profiles if netcdf test fails.
264    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
265    o move call to cal_readparms up to make calendar parameters/variable available
266      to all packages
267    
268    checkpoint58v_post
269    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
270      useDynP_inEos_Zc tested.
271    o pkg/exf: changes to properly interpolate/mask/scale initial fields
272    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
273      and portions thereof.  See read_cs.txt for description and examples.
274    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
275      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
276      following the great-circle arc between those 2 points.
277    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
278      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
279    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
280     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
281     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
282     - still needs work (not working with some options ; efficiency to improve)
283       and serious testing.
284     - use this scheme for temperature & salinity in 2 advection test exp.:
285       advect_xy & advect_xz, respectively.
286    
287    checkpoint58u_post
288    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
289    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
290    o testreport: add option "-skipdir" to skip some test.
291    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
292      momentum calculation.
293    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
294    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
295      remove checkpoint.F and the_correction_step.F (no longer used);
296      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
297    o add option (linFSConserveTr) to correct for tracer source/sink due to
298      Linear Free surface
299    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
300    o pkg/thsice: fix reading mnc-pickups
301    
302    checkpoint58t_post
303    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
304    o pkg/mdsio:
305     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
306       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
307       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
308     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
309     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
310       either MDS_READ_FIELD or MDS_WRITE_FIELD )
311     - new S/R (to replace MDSWRITEMETA), which allows to write more
312       informations (variable names, time ...) to meta files.
313     - modify rdmds.m to give back the meta file content.
314    o pkg/diagnostics: change vertical interpolation to be safer, and more
315       flexible (define p-levels to interpolate to in data.diagnostics);
316      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
317       diagnostic pointer.
318    o pkg/seaice: more cleaning up of seaice_growth, added many comments
319    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
320    o fix multi-category seaice:
321     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
322       SEAICE_MULTICATEGORY
323     - fix short wave heat flux
324    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
325       and allow to use EVP solver. Change forward lab_sea: test both EVP
326       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
327    o Initial check-in of lab_sea adjoint
328      (very similar to natl_box_adjoint/code_seaice)
329      * used C-grid and EVP solver
330      * used KPP, GM/Redi
331      * uses inAdExact=.TRUE.
332      * gradient checks fail for both ADM and TLM
333        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
334        f.d. gradients actually seem more problematic than ADM, TLM gradients;
335        issue is related to forward mismatch between g77 an ifort
336    o pkg/seaice: overhaul of thermodynamics
337     - growth.F and groatb.F are replaced by new routine seaice_growth.F
338     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
339     - move a few global fields out of SEAICE.h into seaice_growth.F and
340       make them 2D (FICE/QNETO/ ...)
341     - remove FO (it is the same as QNETO)
342     - introduce a few local fields to avoid modifying external fields such
343       as atemp, etc.
344    
345    checkpoint58s_post
346    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
347      changed exf_set_gen.F so that
348        genperiod=0 means input file is one time-constant field and
349        genperiod=-12 means input file contains 12 monthly means
350    o CG2D: use pre-computed solver main-diagonal (stored in common block);
351      this affects truncation error ; generate new output file for exp. which
352      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
353        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
354        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
355        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
356        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
357        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
358    o start implementation of deep-atmosphere and anelastic formulation
