8    o adjoint testing: in preparation for changing testreport:
9      - output format: cost and grad written on separated lines
10      - ad output results in directory "results" (instead of "results_ad")
11    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
12    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
13    o pkg/ecco: allow user defined cost function contributions
14    o testreport:
15      Allow to choose (per experiment) the list of tested output variables
16       and the main variable (used to issue a pass/FAIL ) ;
17      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
18      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
19      Also modify printing of summary:
20       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
21       b) echo the list of tested variables in the individual summary.txt of
22          each experiment.
23    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
24      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
25      (but still depend on the tile decompostion of the domain).
26    o pkg/seaice: change a discretization detail to make the B-grid code
27      "more symmetric". This change is likely to remove all "ridges/leads" that
28      where quasi-aligned with the grid in B-grid solutions. It may also be
29      the solution to the stress coupling issues with the B-grid.
30    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
31      remove .cvsignore from input dir. (since testreport no longer run here).
32    o pkg/thsice:
33     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
34     - fix reshaping of sea-ice just after advection:
35       melt all the ice only if ice-volume is too small.
36     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
37       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
38     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
39    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
40      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
41    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
42      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
43      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
44      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
45      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
46      -> update output.txt
47    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
48     this affects truncation error: -> update output.txt of exp:
49      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
50      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
51    
52    checkpoint59f
53    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
54    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
55      a bounded range (in forward mode)
56    o pkg/ecco, ctrl, autodiff and mom_common:
57     internal parameter controls, completements of implementations
58    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
59    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
60      (not seem any difference in testing results).
61    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
62       at face corners.
63    o pkg/generic_advdiff:
64     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
65      loop range indices for computing vertical advection tendency
66      and do the calculation in the interior only (no overlap) ;
67      for now, only implemented for SOM advection (to save CPU time).
68     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
69    o exch2 adjoint
70      First set of changes:
71      - add exch2 hand-written adjoint templates
72      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
73        This will require cleanup in pkg/autodiff/*.F
74        (changed routines currently kept separate in verif. code/)
75      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
76        that used to hide exch2 or cubed-sphere specific code
77        (commented via 'cph-exch2')
78    o pkg/seaice
79      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
80    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
81       output of global_ocean.cs32x15.thsice .
82    
83    checkpoint59e
84    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
85      for B-grid vector (not yet tested) and C-grid vector (<- only used
86      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
87    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
88      (#ifdef ALLOW_SALT_PLUME)
89    o gather_2d/scatter_2d: removed halo regions
90    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
91      scheme and the corresponding test case (under front_relax dir). For now,
92      only available with Skew-flux form and not yet tested in realistic set-up.
93      adjoint: store directives updated, but gradient checks deteriorated,
94      so maybe GM/Redi adjoint is now broken.
95    o seaice adjoint
96      * add AREA, HEFF, HSNOW as control variable
97        (should not change lab_sea results)
98      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
99    o pkg/seaice:
100      * added computation of saltFlux in seaice_growth;
101        For time being, sea ice salinity is assumed constant
102        contribution of snow flooding to freshening of sea ice is neglected.
103        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
104        defaults to 0.0 in order to maintain backward compatibility.
105        Typical values for SEAICE_salinity are 4 to 10 g/kg.
106      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
107      * added SEAICE_availHeatFrac, which specifies fraction of surface level
108        heat content used to melt or grow ice
109      * commented out cap of HICE: it helps keep ice thinner
110      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
111      * applied OBCS T/S mask to HEFFM sea ice mask
112    
113    checkpoint59d
114    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
115     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
116     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
117    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
118     and change default value of parameter "GM_Small_Number";
119     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
120       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
121       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
122    o pkg/ecco: cost function when applying pkg/smooth to controls
123    o pkg/ctrl: add forcingPrecond run time parameter
124    o pkg/seaice:
125     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
126     - fix bug in metric terms of u-equation in LSR solver (implicit part),
127       changes verification/lab_sea
128     - rearrange implicit part of u-equation in LSR solver to make it easier to
129       read, understand, and debug. This causes changes at the truncation level.
130     - fix (serious) bug in the boundary conditions (sign error in the implicit
131       part) of the LSR solver. Changes all LSR results.
132     - fixed problem with HSNOW initialization to avoid thick snow when AREA
133       is initilized with small values - does not change lab_sea results.
134     - added HsnowFile initialization capability
135    o pkg/smooth: addition to model/src and pkg/ctrl so allow
136     initialization of pkg/smooth and application to control vector
137    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
138    o dependencies: pkg/profiles requires pkg/cal
139    o pkg/profiles:
140     - added option ALLOW_PROFILES_GENERICGRID
141         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
142         that interpolation information (grid points and coefficients) is provided
143         within the netcdf input files.
144         -> sample matlab scripts can be found in MITgcm_contrib/gael
145         that allow you to prepare netcdf input files.
146     - also modified: cleaner include statements, cleaner error print statements,
147       cleaner stops when error, and more tests of the netcdf input files consistency.
148    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
149    o pkg/seaice:
150     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
151       requires a new routine: seaice_diagnostics_fill.F
152     - make sure that seaice does not move if not forced (pressure replacement
153       method, Hibler and Ip, 1995), changes results
154     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
155     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
156       It is turned off by default (=-1.), because it changes the results.
157     - make it possible to read AREA from a file, too.
158    
159    checkpoint59c
160    o add S/R and diagnostics for oceanic mixed-layer depth
161    o move GMRedi call after all vertical mixing schemes (including KPP)
162    o pkg/thsice:
163     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
164      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
165    o pkg/obcs:
166     - bug fix for balance code
167    o pkg/seaice:
168      - allow values of SEAICE_elasticParm > 1
169      - add new parameter SEAICE_evpTauRelax as an alternative
170        to SEAICE_elasticParm
171      - make lsr boundary conditions free slip (by default), changes result
172      - add code for no slip boundary conditions for lsr
173      - set minimum of zeta to zero (and not 4e8) (changes results)
174      - add a cap on AREA after advecting AREA if seaice_growth is not called
175    o change calculation of Visbeck K:
176      - no longer depend on tapering scheme; instead, compute slope (limited
177        by GM_maxSlope). this is equivalent to what was comuted before with
178        clipping or linear tappering.
179      - fix vertical averaging (wrong by 1/2 level)
180      - leave the old version (but will not be maintained) within
181        #ifdef OLD_VISBECK_CALC / #endif
182      - update output of exp. ideal_2D_oce
183    o change error catch in calc_r_star to improve vectorization
184    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
185      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
186    o adjoint:
187      Re-organized adjoint checkpointing according to Matt Mazloff
188      (but with modifs/completions/cleanups)
189      Storing is now bundled into large arrays to optimized I/O
190      (and second step in cleanup of the_main_loop)
191    
192    checkpoint59b
193    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
194      - export/import (between ocean & coupler) fields needed for ocean DIC.
195    o pkg/seaice:
196      - get rid of three more exchanges seaice_calc_viscosities (required
197        different loop boundaries in seaice_lsr and seaice_ocean_stress)
198      - bug fix in seaice_ocean_stress (update of lab_sea required)
199      - reduce loop boundaries to necessary minimum also in seaice_evp
200      - go back to the old way of computing deltaC/Z as the adjoint likes that
201        better
202    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
203      passive tracer to an Age Tracer) + update output.txt
204    o pkg/exf:
205      - implement A-grid / C-grid selection for wind-stress input files.
206      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
207      for now, in exf_bulk_largeyeager04.F only :
208      - change implementation for case where windspeed + 2. components wind-stress
209        are read-in. AND use rhoConstFresh to convert evap.
210    o pkg/seaice:
211      - use correct EXCH_UV for wind-forcing (on A-grid).
212      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
213        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
214    o pkg/exf:
215      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
216      EXF_INTERPOLATION:
217      - merge global_with_exf/code version of exf_interp_read.F
218        to the main code ;
219      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
220        reading the file ; Important: This options needs to be defined to recover
221        previous code.
222        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
223      - no longer loose real*8 precision along the way when using exf_iprec=64.
224    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
225      - change discretisation of evp-solver in order to avoid another exchange
226        (changes lab_sea) and clean up a little
227      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
228        help the adjoint (this also changes the results slightly)
229      - add a few "_d 0" where they had been missing in seaice_evp.F
230      - cleaning up: remove unused seaice_calc_rhs.F
231    o pkg/exf: some cleaning-up:
232      - change various "constants" into runtime parameters
233      - cleaned-up Large&Yeager04 routine which should eventually
234        replace exf_bulkformulae.F (changed names of S/R and CPP)
235        and merged various ALLOW_ATM_WIND options
236     only used with thsice pkg (in thsice_get_exf.F):
237      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
238        which are used when useStabilityFct_overIce=TRUE (= the default)
239      - change default values of ice & snow emissivity and scale downward LW
240        by ice & snow emissivity.
241    o pkg/thsice:
242     fix few little problems, in thsice_calc_thickn.F:
243      - growth vertically (and not laterally) if iceFrac == iceMaskMax
244      - melt only laterally if hIce < hThinIce (as the comments say)
245      and in thsice_extend.F:
246      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
247      - start to form ice as soon as the minimum ice-volume is reachable.
248     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
249      and cpl_aim+ocn
250    o pkg/kpp
251     - move computation of surface related input fields to KPP into a new
252       subroutine kpp_forcing_surf.F
253     - remove wrong (within bi,bj loops) EXCH calls.
254     - little cleaning (add argument myThid in last position, cvs header ...)
255     - for now, fix conservation problem by exchanging KPPviscAz (may not
256       be the best fix)
257    o pkg/seaice
258     - check for inconsistent evp parameter/cpp-flag combination
259     - remove leftover errIO flat for obsolete name list error handling
260    o OpenAD
261     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
262    
263    checkpoint59a
264    o pkg/seaice: some parameter clarifications and a little bit of clean up
265    o pkg/thsice: rename run-time parameters:
266       himin       -> hIceMin
267       himin0      -> hThinIce
268       hihig       -> hThickIce
269       i0          -> i0swFrac
270       transCoef   -> bMeltCoef
271       frac_energy -> fracMelting
272      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
273       with default values (for now) that do not change the results.
274      remove old version of thsice vars advection in pkg/seaice.
275  o in FFIELDS.h:  o in FFIELDS.h:
276    - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD    - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
