4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o eesupp & mdsio (SingleCpuIO):
8     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
9       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
10       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
11     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
12     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
13       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
14    o pkg/exch2:
15     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
16       read parameter file "data.exch2" if it exists; otherwise try default regular
17       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
18     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
19       with new code (not to be used, just as a backup solution).
20     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
21       in utils/exch2/input.
22    
23    checkpoint61n
24    o eesupp & mdsio (SingleCpuIO):
25      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
26        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
27        receive real*4 array (instead of real*8) to read/write 32.bit files.
28        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
29         and remove new mapping S/R)
30    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
31      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
32        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
33        when using exch2. Add S/R to map global io-buffer to global model array.
34      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
35    
36    checkpoint61m
37    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
38      and add 3 other S/R for other types (R4,R8,RS).
39      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
40    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
41     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
42     - reduce number of macro definitions (keep only those which are used);
43       can always call directly the corrresponding S/R if needed.
44     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
45       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
46     Fixed wrong type of arg in:
47       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
48       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
49     To fix: global_sum of var in common block is wrong (multi-threaded) in:
50       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
51     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
52    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
53      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
54    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
55    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
56      edges are closed (zero depth); might happen with "blank tiles";
57      for now, disabled if using OBCS.
58    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
59      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
60    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
61      to reduce length of 1.D array print in STDOUT.
62    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
63      + use 48 tiles (16x8): this will allow to test "blank tiles".
64    o start to test MPI + multi-threaded (change testreport to skip tests
65      where number of tiles do not match).
66    o genmake2: add option "-omp" to turn on Open-MP ;
67      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
68    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
69      and keep the original tile numbering. Note: compatible with old
70      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
71    
72    checkpoint61l
73    o Overlaps had been forgotten in calculating ijk keys : fixed
74    o fix cyrus makedepend for gcc 4.4
75    o experiment fizhi-cs-aqualev20:
76      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
77      and generate new output. Note: new output is much closer to the old
78      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
79      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
80    o pkg/fizhi:
81     - change to avoid indices going deliberately over array-bounds
82     - remove unnecessary MPI stuff
83     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
84     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
85       does not go over array-bounds and therefore returns reliable output.
86     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
87       this S/R has 4 output arguments, which are used inside "get_alarm";
88       when it is called with the same variable "ndum" in place of several
89       output arguments, this produces weird side effect inside "get_alarm"
90      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
91       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
92       address) and produces error.
93    o tools/gemake2: (March 27-29 2009)
94      with option "-mpi": link *_mpi files from "MODS" dir (this is what
95      testreport does).
96    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
97    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
98       update lab_sea.lsr & lab_sea.salt_plume results
99    o pkg/seaice:
100      Major overhaul of the LSOR solver: change discretization from original
101      finite differences to finite volume. The old routine is still in the
102      file seaice_lsr.F and can be turned on with the CPP-flag
103      SEAICE_OLD_AND_BAD_DISCRETIZATION
104      Along with this change, the discretization of the strain rates is changed.
105      The same flag turns on the old discretization in seaice_calc_strainrates.F
106      All verification experiments with seaice are affected (except for
107      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
108      results by setting the above flag.
109      Further changes involve changes in defaults:
110      - ALLOW_FLOODING is defined and turned on by default
111      - SEAICEadvSnow = .true. is now the default
112      - SEAICEadvSalt = .true. is now the default
113      - SEAICEadvAge  = .true. is now the default
114      - SEAICE_clipVelocities  = .false. is now the default
115                                         (as per J. Zhang's recommendation)
116      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
117        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
118      - seaice_growth: replace computation of UG by a simple copy from wspeed
119    
120    checkpoint61k
121    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
122      seaice_lsr: fixed a few metric terms,
123                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
124                  add more debugging diagnostics
125      seaice_evp: removed superfluous many metric terms of FV discretization
126                  of stress divergence
127                  affects lab_sea, lab_sea.hb87
128      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
129                  of stress divergence for non-evp solver
130                  (this part is not tested anywhere)
131      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
132                  they were effectively only half slip
133                  affects lab_sea.hb87
134      updated all relevant verification experiments (except lab_sea//output_adm.txt
135        which was left over, but fails at level 7 & 6)
136    
137    checkpoint61j
138    o pkg/seaice: turn a few hard wired parameters into run time parameters
139    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
140      time in seconds as promised by the usints in seaice_monitor and exf_monitor
141    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
142      that are not cubed-sphere grids
143    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
144    o pkg/ctrl:
145      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
146    o non-hydrostatic (calc_gw.F):
147      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
148      update output of exp. global_ocean.cs32x15.viscA4
149    o remove backward compatibility for thetaMin,phiMin
150      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
151    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
152      interpolated wind field not only for curvilineargrid=.true., but also
153      for a rotated grid (rotateGrid=.true.)
154    o pkg/exf: add capability to bypass interpolation for runoff
155      by setting yet another CPP-flag
156    o eesupp/src, B-grid exchange:
157      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
158    o autodiff
159      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
160      allows to switch to single-prec common blocks;
161      corresponding switch occurs in tamc.h, integer isbyte
162      TAF store directivs "byte" and "kind" seem equivalent;
163      Most tamc.h have been updated correspondingly.
164    
165    checkpoint61i
166    o autodiff:
167      fix autodiff_sore/_restore indices for obcs
168      (spotted by I. Hoteit, M. Mazloff)
169    o pkg/autodiff, pkg/ctrl:
170      Add flag to reduce all tapelev I/O to single-prec.
171      In data.ctrl set
172        doSinglePrecTapelev = .TRUE.
173    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
174      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
175    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
176      real fresh water flux (not yet)
177    o pkg/mdsio & rw:
178     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
179     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
180    o pkg/flt:
181     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
182       init_fixed & ini_varia.
183     - clean-up & simplify linear interpolation S/R:
184       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
185     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
186     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
187     - add vert. coordinate & horiz. indices to output files.
188     - change vertical position in initial condition, from index to depth [m].
189     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
190       (easier to get to a curvilinear grid) ; delX,delY no longer used.
191    o pkg/ggl90: a few modifications:
192     - fix bottom boundary condition, and interpolation of KappaE
193       near top and bottom
194     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
195     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
196     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
197    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
198      (maintain temporary backward compatibility, until next checkpoint)
199    
200    checkpoint61h
201    o pkg/diagnostics with "periodic averaging diagnostics":
202      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
203    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
204    o pkg/obcs: fix loop ranges for balancing code
205    o pkg/flt:
206     - improve criteria for finding which tile owns a float.
207     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
208    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
209      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
210      with ocean biogeo)
211    o pkg/flt:
212     - do some cleaning and fix the restart ;
213     - add output.txt in flt_example/results to get this pkg tested.
214    o genmake2: add an EXTENDED_SRC option and flag.
215       for now, cannot be turned on on command line (only through genmake_local)
216    o pkg/mdsio: read/write vector:
217     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
218     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
219       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
220     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
221      (drop to 4 digits matching for grad). But this test does not look very
222      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
223    
224    checkpoint61g
225    o pkg/flt:
226      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
227       + make OPTIONS file more standard.
228      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
229      - fix _BYTESWAPIO CPP-Flag
230      - standard reading of file-parameter "data.flt"
231      - fix argument list of S/R FLT_RESTART
232      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
233    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
234    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
235      a still unfixed compiler/optimization bug
236    
237    checkpoint61f
238    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
239      update results of global_ocean.cs32x15.icedyn test.
240    o move getcon.F from model/src to pkg/fizhi.
241    o pkg/exf: add parameter for extrapolation of temp up to the surface
242       and option to prevent negative evap (in bulk_largeyeager04 only).
243    o Prather Advection scheme: fix tracer conservation for divergent flow
244      (e.g., when using NonLin Free-Surface).
245    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
246    o gmredi (Visbeck-variable-K):
247     - add more parameters to Visbeck-variable-K.
248     - use a 5 points average for dSigmaR in Visbeck-K calculation
249       (more "homogenous": same stencil and same weights as in dSigmaH)
250     - update output of ideal_2D_oce experiment.
251    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
252      (#undef REAL4_IS_SLOW)
253     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
254       coordinate variable
255     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
256       (surface forcing fields), removes some of the functionality
257     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
258     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
259       probably not all: copy _RS surface flux fields to RL field before
260       calling DIAGNOSTICS_FILL
261     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
262       real*4 (CALL EXCH_*_RS) versions.
263     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
264       (generate new output).
265    
266    checkpoint61e
267    o gmredi (Visbeck-variable-K):
268      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
269      - change computation of Visbeck-K where Slope > Smax :        
270        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
271        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
272    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
273      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
274    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
275    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
276      does not become too large (to avoid precision problems in implicit-diffusion
277      solver); update ideal_2D_oce output.
278    o pkg ggl90:
279      - in ggl90_cal.F: compute only one set of visc/diff, used to
280        step forward TKE/T/S/momentum
281      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
282        have Prandlt =1)
283    o gmredi (fm07):
284      - add lower limit on Transition layer thickness + lower limit on 1/lambda
285      - allow to set few more params from data.gmredi
286    o pkg ggl90:
287          - add missing sqrt(2) factor in computation of mixing length
288            scale in ggl90_calc.F
289            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
290    
291    checkpoint61d
292    o adjoint modifs
293      - adapt to new field rhoInSitu
294      - allow to revert from StoreDynVars2D, StoreDynVars3D
295        to individual fields
296        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
297    o store 3-D (in-situ) density in commom block (DYNVARS.h)
298     - save 1 rho computation.
299     - no longer modify T & S inland when using down_slope pkg.
300    o gad_som : allow to switch to SOM advection for T & S without corresponding
301      pickup files (using new S/R: MDS_CHECK4FILE).
302    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
303      (for useSingleCpuIO to work in multi-threaded)
304    o pkg/shelfice:
305     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
306       with SHELFICEtopoFile in data.shelfice
307     - move code for reading ice shelf topography and modifying hFacC into separate
308       subroutines of the shelfice package
309     - separate initialisation of "fixed" and "variable" variables
310     - kTopC is not (yet) replaced by kSurfC, although this is possible
311    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
312    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
313      and rename:
314      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
315      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
316    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
317    
318    checkpoint61c
319    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
320      to add mass source/sink of fluid in the interior (3-D generalisation
321      of oceanic real-fresh water flux).
322    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
323    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
324    o new pkg: down_slope
325      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
326      - presently, modify T & S inland (dwnslp_calc_rho.F).
327        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
328      - implementation for ocean in P-coords not tested.
329      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
330    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
331      (to facilitate conversion of oceanic pkg to p-coordinate).
332    o change FIND_RHO to FIND_RHO_2D :
333      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
334    o new pkg: cheapaml
335    
336    checkpoint61b
337    o exch2:
338      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
339      - no longer depend on the order sequence (N,S,E,W).
340      - 3rd exchange no longer needed (tested with 24 tiles).
341      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
342      - exch_UV_A-grid readily available (but not yet tested).
343      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
344      (both are no longer needed) in exch_uv: no effect in forward run; but
345       get truncation error differences with adjoint exch.
346    o exch2:
347     - change index-bounds storage (moved from target to local tile,
348       more intuitive this way) ; rename/remove some variables.
349     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
350    
351    checkpoint61a
352    o exch2/matlab-topology-generator:
353      fix bug in index bounds for N-S internal exchange (hard to tell if this
354      had any effect on the solution).
355    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
356      is exceeded
357    o testreport: modify syntax of awk, so that it works also with
358      awk, and not only with nawk and gawk
359    
360    checkpoint61
361    o autodiff
362      Change default for TAF usage by removing argument '-nonew_arg'
363      This changes TAF subroutine argument list (ordering of active var.)
364      Omission of this flag leads to incompatibility w.r.t. TAMC
365      To restore TAMC-compatibility, need following modifs:
366      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
367      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
368      Tested TAF version is 1.9.22
369      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
370    
371    checkpoint60
372    --->>> This is the last checkpoint for which generating the adjoint
373    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
374    --->>> by default.
375    --->>> Future checkpoints will ommit this flag by default.
376    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
377    o pkg/grdchk: Add gradient check to etan0 perturbations.
378    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
379    o pkg/autodiff: more flexibility in zeroadj.
380      model/src: modifying do_oceanic_phys.F accordingly.
381    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
382    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
383      special setup of gmredi for which the adjoint is stable
384      enough for parameter optimization.
385    o bridging the gap between eddy stress and GM.
386      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
387          along with a change in CPP option (now ALLOW_EDDYPSI).
388      -> when using GM w/ GM_AdvForm:
389          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
390          is applied either in the tracer Eq. or in momentum Eq.
391          depending on data.gmredi (intro. GM_InMomAsStress).
392      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
393      The key modifications are in model/src/taueddy_external_forcing.F
394      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
395    
396    checkpoint59r
397    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
398      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
399      fix option to read coriolis(@ cell-corner) from files with CS-grid.
400    o pkg/mnc: add some attributes to standard 1D-coordinate variables
401    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
402      mass points, when using mnc for output
403      - add runtime parameter (missing_value, missing_value_int) to override
404        default (which is the value of getcon('UNDEF'))
405    o pkg/mnc: prepare mnc for the actual use of missing values with the
406      diagnostics package: small fix in mnc_cw_readwrite.template and more
407      initialisation of never used fields
408      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
409      versions
410    o pkg/thsice/thsice_ini_vars.F added default initial values so that
411      thermodynamics sea ice solver does not blow up when some initial fields
412      are missing.
413    o move from external_forcing_surf.F to ini_forcing.F
414      the p-coord. hack consisting in using pLoad to set phi0surf ;
415      update output of tutorial_global_oce_in_p (affected @ truncation level).
416    o Freshen up a bit hs94.1x64x5, notably:
417      remove rotationPeriod and tRef=5*0. (adjoint only), and add
418      exactConserv=.TRUE.
419    o pkg/generic_advdiff:
420      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
421      applies to files where Temperature & Salinity 2nd Order moments are used.
422    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
423      this uses a dynamically allocated internal state data structure
424      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
425      and requires a fortran 90 compiler
426    
427    checkpoint59q
428    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
429       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
430    o Refresh tutorial_global_oce_biogeo, notably:
431      - change bathymetry (put back seamounts in ACC, use hFacs)
432      - change EOS (POLY3 --> JMD95Z)
433      - use Bryan-Lewis vertical diffusivity
434      - use multidimensional advection
435      - remove old virtual virtual in dic pkg, now done through ptracer pkg
436      - change a couple of parameters in dic pkg
437    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
438    o pkg/obcs: change default to OBCSfixTopo = .true.,
439      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
440      - replace "debugMode" with "debugLevel .GE. debLevB"
441    o implementation of TAF directives for gchem,cfc,dic
442    o remove "exp5" (replaced by tutorial_deep_convection).
443    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
444      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
445      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
446      --> changes results in exp4, seaice_obcs
447    o tutorial_deep_convection :
448      update the set-up and increase resolution and domain size ; start
449      from pseudo initial conditions = output at t=120mn in order to see
450      something happening when running testreport.
451    o pkg/seaice: add os7mp as an advection scheme
452                  add check for advection schemes
453                  add a flag for restoring T and S underneath sea ice
454    o pkg/my82: add netcdf-support and diagnostics
455    o thsice pkg:
456      - Now hsMax limits snow height by turning it into ice following
457        flooding scheme (and now conserving energy)
458      - Slight rewriting of the formula in thsice_calc_thick.F
459      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
460      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
461    
462    checkpoint59p
463    o gchem / dic / cfc :
464      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
465      - add new parameter files: "data.dic" & "data.cfc" ;
466      - various re-arrangement in initialisation & header file ;
467      - fix tutorial_global_oce_biogeo for multi-threaded test.
468    o pkg/dic: test for "pickup_dic" file when restarting ;
469      if no pickup-file, can restart with a re-initialised pH (same as it did
470      before) providing pickupStrictlyMatch is set to False.
471    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
472      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
473    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
474      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
475    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
476     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
477       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
478    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
479       scheme to use for vorticty-term ;
480     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
481       (with default selectVortScheme, return to original discretisation)
482     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
483    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
484    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
485      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
486      also fix diagnostics VISCAHW & VISCA4W.
487    
488    checkpoint59o
489    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
490    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
491      move a few statemens out the main loop into separate loops
492    o pkg/shelfice:
493      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
494        (kg/m^2/s), does not break tests, because in verification/isomip,
495        rhoConstFresh=rhoConst (by accident)
496      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
497      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
498        new file model/src/seawater.F, so that they are available for all pkgs.
499      - convert potential temperature into in-situ temperature. This changes the
500        isomip tests => update tests
501    o add a flag writePickupAtEnd (default=true) to be able to suppress
502      writing a pickup at the last timestep
503    o tools/mpack-1.6 :
504      - disable automake (not working) and autoconf (not needed).
505      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
506        also cleaner with much less compilation warnings.
507    o pkg/profiles:
508      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
509      (for "less than 32 characters name" compiler requirement)
510    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
511      conditions that have a different sampling frequency than S/T/U/V obcs
512    o pkg/diagnostics (stats-diags):
513      - fix global Min/Max in case 1 processor get only empty tiles
514    o genmake2: replace (4 times)
515         make genmake_tc_1.o >> genmake_warnings 2>&1
516      with
517         COMM="$CC $CFLAGS -c genmake_tc_1.c"
518         echo $COMM >> genmake_warnings
519         $COMM >> genmake_warnings 2>&1
520      to make genmake2 always see the value of CC as specified in the optfile.
521    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
522      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
523      - modify verification advect_cs test to test SOM-advection on CS-grid.
524    o pkg/ctrl:
525      - Rewrite of ctrl_map_ini_ecco.F,
526        introducing a generic routine (ctrl_map_ini_gen.F).
527      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
528    
529    checkpoint59n
530    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
531      number in dedicate array "hdiag":
532      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
533        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
534      - many small changes (integer format) for large number of diagnostics
535      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
536        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
537    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
538      usingSphericalGrid, this allows to define the rotated grid coordinates
539      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
540      geographical coordinates according to the inverse of the rotation defined
541      by the Euler angles, so that Coriolis parameter and online-interpolation by
542      exf works with the geographical coordinates on XC/YC/XG/YG.
543      Naturally, this feature does not work with all packages, so some
544      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
545      profiles), because there the coordinates are assumed to be regular
546      spherical grid coordinates.
547    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
548      - introduce isopycnal diffusion coefficient control.
549    o tools/adjoint_options:
550      - additional control vector components.
551    o pkg/mnc: have mnc create marginally meaning full coordinate variables
552      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
553    o pkg/mypackage:
554      - add example of read/write pickup for state-var ;
555      - add entry points to the main code for state-vars diags & write-pickup.
556    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
557      transitions for useExfYearlyFields
558      - add new subroutine that determines the file to read from for
559        use*YearlyFields = .TRUE. and .FALSE.
560      - add a verification experiment to global_with_exf that tests
561        useExfYearlyFields with USE_EXF_INTERPOLATION defined
562    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
563      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
564      subroutines (which could be generated from a template, because they are
565      almost identical), for now they are included in obcs_prescribe_read.F for
566      simplicity
567    o pkg/exf:
568      - add a little more diagnostic to exf_interp_read (in analogy to
569        mds_read_field, can be turned off with debugLevel < debugLevA=1)
570      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
571        ugly but fast by unrolling short inner loops, inserting a unroll=8
572        directive in routine lagran, and splitting a loop and making do while the
573        outermost loop (the latter requires the intoduction of index arrays)
574    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
575    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
576      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
577    o verification/seaice_obcs: updated for restart test and latest options
578    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
579      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
580      for now this is only available for the C-grid code and also within
581      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
582    
583    checkpoint59m
584    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
585      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
586    o gad_som : fix flux output (& diagnostics) to have same units as other  
587      advection scheme fluxes (was previously multiplied by deltaT).  
588    o added verification/seaice_obcs both to test seaice open boundaries
589      and to provide an example matlab scrpt for generating them
590    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
591    o pkg/salt_plume: clean up salt_plume_frac.F to
592      remove redundancy in PlumeMethod 1 and 4
593    o pkg/kpp: added saltplume diagnostics
594    o pkg/obcs and pkg/seaice:
595      - do not set uice and vice to zero when OB*icefile are unspecified
596      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
597      - moved seaice tracer obcs after call to seaice_growth
598    o pkg/salt_plume: added various options for salt plume depth
599      criterion and for vertical distribution of the salt
600    
601    checkpoint59l
602    o pkg/ptracers: new version of ptracers pickup:
603      read meta file and write only fields which are needed to restart.
604      ( same logic as main pickup file ; also using pickupStrictlyMatch )
605    o pkg/seaice:
606      - add timescale for melting due to warm mixed layer as a means of
607        setting SEAICE_availHeatFrac more conveniently
608      - add a CPP-flag/runtime parameter check for flooding algorithm
609      - reformulated availHeat in seaice_growth.F to be independent of AREA
610    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
611      unit changes
612    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
613    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
614      SX vector computer.
615    o pkg/seaice:
616      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
617        seaice forcing fields can now be read only through pkg/exf
618      - removed some unused halos
619    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
620    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
621      or U/VICE from U/VWIND before computing U/VSTRESS
622    
623    checkpoint59k
624    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
625      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
626    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
627      all experiments pass when compile with un-initialised var. checking option.
628    o added pkg/salt_plume
629    o script to test restart (for now, in MITgcm_contrib/jmc_script)
630    o pkg/seaice: new read/write pickup version.
631      read meta file and write only fields which are needed to restart.
632      ( same logic as main pickup file ; also using pickupStrictlyMatch )
633    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
634    o lab_sea.hb87: modify the domain & update output.hb87.txt :
635      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
636      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
637      process. Fixed here by closing the domain at the Northern boundary.
638    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
639    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
640      a set of consecutive levels in/from a 3-D array.
641    o pkg/ptracers:
642      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
643      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
644    
645    checkpoint59j
646    o in pkgs: dic, obcs, offline, rbcs:
647      standard way to compute coeff. for time interpolation between 2 time reccords
648      which retains full precision (& make results less dependent on compiler).
649      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
650    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
651      packages instead of reading ice cover and wind speed separately
652    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
653     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
654      to allow to compile customized code before the update)
655    o cleaning-up:
656      - fix CPP instruction syntax in pkg/obcs
657      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
658        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
659      - fix some threads issue in IO parts.
660    o pkg/dic:
661      - add tons of "_d 0" (--> much better testreports !)
662       and then update outputs of tutorial_global_oce_biogeo
663    o pkg/mom_fluxform:
664      add a special version of momentum advection intended to conserve momentum
665      next to a bathymetry step or a coastline edge. (default = off = #undef)
666    o new read/write pickup version:
667      - for now, only implemented for main (mdsio) pickup file.
668      - write out only what is needed to restart; merge pickup_nh , pickup_ph
669        and main pickup together.
670      - read meta file; read only what is needed to restart; stop if a field
671        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
672        if it make sense (even if the restart is not perfect).
673      - if no meta file, assume that pickup to read corresponds exactly to
674        a pickup that would currently be written.
675      - read pickup written in the old format (until checkpoint59i) if it
676        recognizes an old meta file (no field-list).
677      - add a meta file in exp. which starts from a pickup: 2 cases:
678        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
679         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
680        b) a meta file describing the content of the associated pickup file
681         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
682    o pkg/mdsio & pkg/rw:
683      - new routine to read a meta file ; new set of routine to read
684        Multiple-fields file (with meta file).
685    o added open boundary conditions capability for seaice
686        HSNOW, HSALT, UICE, and VICE
687    
688    checkpoint59i
689    o adjoint:
690      * fix multiDimAdvection adjoint
691        (partial recomputation problem by TAF for fVerT(:,:,kDown)
692        and comlev1 size definition (maxpass vs. max. number of tracers)
693      * verification/global_ocean.90x45x15 adjoint now tests
694        NLFS and multiDimAdvection using DST3 (=30)
695      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
696    o pkg/kpp: add "_d 0" to real constant (if missing);
697      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
698      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
699    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
700      for internal parameters related to restart process (formerly from PARAMS.h)
701      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
702    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
703      as argument. (only atm2d & obcs write_pickup have not yet been updated)
704    o pkg/monitor:
705      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
706      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
707      - account for deep Atmosphere factor and density factor (anelastic)
708    o added open boundary conditions capability for seaice HEFF and AREA
709    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
710      thermodynamics
711      - requires a little reorganization, which affects the testreport results
712        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
713        so that now the conservative form is tested
714      - add a few comments
715    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
716    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
717    o add new diagnostics to seaice: advective, diffusive fluxes (only for
718      multidim-advection, for scheme 2 they are not filled) and transports,
719      thermodynamic growth rates
720    o change units of EmPmR (inside the code, + within coupling interface)
721      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
722      Affects results @ truncation level (cg2d match) and update output of
723       experiments: lab_sea(6), global_ocean.90x40x15(10),
724      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
725      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
726      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
727      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
728    
729    checkpoint59h
730    o pkg/exf:
731      - improve vectorization by moving if-statement out of loops in
732        exf_mapfields, exf_radiation
733      - exf_bulkformulae.F: introduce 2D fields and vectorize code
734    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
735    o testreport:
736      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
737        monitor & update offline_exf_seaice exp. output.
738      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
739    o pkg/seaice:
740      - bug fix in the evp solver: boundary conditions were affected be
741        masking of zMax/zMin (changes results)
742      - minor bug fix in boundary conditions in seaice_calc_strainrates
743        (changes results for no_slip)
744      - seaice_lsr.F: make interpolation of eta dependent on boundaries
745      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
746      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
747        stress formulation and no-slip boundary conditions
748    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
749      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
750    o pkg/seaice: a first HSALT time stepping equation has been checked in
751    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
752      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
753      without requiring DO-IF statements
754    o pkg/thsice:
755      use continuous power-law function for partition of energy between lateral
756      melting/freezing and thinning/thickening ; old code using step function
757      still available with #undef THSICE_FRACEN_POWERLAW
758      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
759    o testreport: change AD testing : check against results/output_adm.txt
760      using same scripts as for forward test.
761    
762    checkpoint59g
763    o adjoint testing: in preparation for changing testreport:
764      - output format: cost and grad written on separated lines
765      - ad output results in directory "results" (instead of "results_ad")
766    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
767    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
768    o pkg/ecco: allow user defined cost function contributions
769    o testreport:
770      Allow to choose (per experiment) the list of tested output variables
771       and the main variable (used to issue a pass/FAIL ) ;
772      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
773      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
774      Also modify printing of summary:
775       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
776       b) echo the list of tested variables in the individual summary.txt of
777          each experiment.
778    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
779      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
780      (but still depend on the tile decompostion of the domain).
781    o pkg/seaice: change a discretization detail to make the B-grid code
782      "more symmetric". This change is likely to remove all "ridges/leads" that
783      where quasi-aligned with the grid in B-grid solutions. It may also be
784      the solution to the stress coupling issues with the B-grid.
785    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
786      remove .cvsignore from input dir. (since testreport no longer run here).
787    o pkg/thsice:
788     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
789     - fix reshaping of sea-ice just after advection:
790       melt all the ice only if ice-volume is too small.
791     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
792       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
793     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
794    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
795      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
796    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
797      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
798      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
799      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
800      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
801      -> update output.txt
802    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
803     this affects truncation error: -> update output.txt of exp:
804      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
805      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
806    
807    checkpoint59f
808    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
809    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
810      a bounded range (in forward mode)
811    o pkg/ecco, ctrl, autodiff and mom_common:
812     internal parameter controls, completements of implementations
813    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
814    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
815      (not seem any difference in testing results).
816    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
817       at face corners.
818    o pkg/generic_advdiff:
819     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
820      loop range indices for computing vertical advection tendency
821      and do the calculation in the interior only (no overlap) ;
822      for now, only implemented for SOM advection (to save CPU time).
823     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
824    o exch2 adjoint
825      First set of changes:
826      - add exch2 hand-written adjoint templates
827      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
828        This will require cleanup in pkg/autodiff/*.F
829        (changed routines currently kept separate in verif. code/)
830      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
831        that used to hide exch2 or cubed-sphere specific code
832        (commented via 'cph-exch2')
833    o pkg/seaice
834      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
835    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
836       output of global_ocean.cs32x15.thsice .
837    
838    checkpoint59e
839    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
840      for B-grid vector (not yet tested) and C-grid vector (<- only used
841      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
842    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
843      (#ifdef ALLOW_SALT_PLUME)
844    o gather_2d/scatter_2d: removed halo regions
845    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
846      scheme and the corresponding test case (under front_relax dir). For now,
847      only available with Skew-flux form and not yet tested in realistic set-up.
848      adjoint: store directives updated, but gradient checks deteriorated,
849      so maybe GM/Redi adjoint is now broken.
850    o seaice adjoint
851      * add AREA, HEFF, HSNOW as control variable
852        (should not change lab_sea results)
853      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
854    o pkg/seaice:
855      * added computation of saltFlux in seaice_growth;
856        For time being, sea ice salinity is assumed constant
857        contribution of snow flooding to freshening of sea ice is neglected.
858        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
859        defaults to 0.0 in order to maintain backward compatibility.
860        Typical values for SEAICE_salinity are 4 to 10 g/kg.
861      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
862      * added SEAICE_availHeatFrac, which specifies fraction of surface level
863        heat content used to melt or grow ice
864      * commented out cap of HICE: it helps keep ice thinner
865      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
866      * applied OBCS T/S mask to HEFFM sea ice mask
867    
868    checkpoint59d
869    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
870     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
871     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
872    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
873     and change default value of parameter "GM_Small_Number";
874     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
875       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
876       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
877    o pkg/ecco: cost function when applying pkg/smooth to controls
878    o pkg/ctrl: add forcingPrecond run time parameter
879    o pkg/seaice:
880     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
881     - fix bug in metric terms of u-equation in LSR solver (implicit part),
882       changes verification/lab_sea
883     - rearrange implicit part of u-equation in LSR solver to make it easier to
884       read, understand, and debug. This causes changes at the truncation level.
885     - fix (serious) bug in the boundary conditions (sign error in the implicit
886       part) of the LSR solver. Changes all LSR results.
887     - fixed problem with HSNOW initialization to avoid thick snow when AREA
888       is initilized with small values - does not change lab_sea results.
889     - added HsnowFile initialization capability
890    o pkg/smooth: addition to model/src and pkg/ctrl so allow
891     initialization of pkg/smooth and application to control vector
892    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
893    o dependencies: pkg/profiles requires pkg/cal
894    o pkg/profiles:
895     - added option ALLOW_PROFILES_GENERICGRID
896         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
897         that interpolation information (grid points and coefficients) is provided
898         within the netcdf input files.
899         -> sample matlab scripts can be found in MITgcm_contrib/gael
900         that allow you to prepare netcdf input files.
901     - also modified: cleaner include statements, cleaner error print statements,
902       cleaner stops when error, and more tests of the netcdf input files consistency.
903    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
904    o pkg/seaice:
905     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
906       requires a new routine: seaice_diagnostics_fill.F
907     - make sure that seaice does not move if not forced (pressure replacement
908       method, Hibler and Ip, 1995), changes results
909     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
910     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
911       It is turned off by default (=-1.), because it changes the results.
912     - make it possible to read AREA from a file, too.
913    
914    checkpoint59c
915    o add S/R and diagnostics for oceanic mixed-layer depth
916    o move GMRedi call after all vertical mixing schemes (including KPP)
917    o pkg/thsice:
918     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
919      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
920    o pkg/obcs:
921     - bug fix for balance code
922    o pkg/seaice:
923      - allow values of SEAICE_elasticParm > 1
924      - add new parameter SEAICE_evpTauRelax as an alternative
925        to SEAICE_elasticParm
926      - make lsr boundary conditions free slip (by default), changes result
927      - add code for no slip boundary conditions for lsr
928      - set minimum of zeta to zero (and not 4e8) (changes results)
929      - add a cap on AREA after advecting AREA if seaice_growth is not called
930    o change calculation of Visbeck K:
931      - no longer depend on tapering scheme; instead, compute slope (limited
932        by GM_maxSlope). this is equivalent to what was comuted before with
933        clipping or linear tappering.
934      - fix vertical averaging (wrong by 1/2 level)
935      - leave the old version (but will not be maintained) within
936        #ifdef OLD_VISBECK_CALC / #endif
937      - update output of exp. ideal_2D_oce
938    o change error catch in calc_r_star to improve vectorization
939    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
940      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
941    o adjoint:
942      Re-organized adjoint checkpointing according to Matt Mazloff
943      (but with modifs/completions/cleanups)
944      Storing is now bundled into large arrays to optimized I/O
945      (and second step in cleanup of the_main_loop)
946    
947    checkpoint59b
948    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
949      - export/import (between ocean & coupler) fields needed for ocean DIC.
950    o pkg/seaice:
951      - get rid of three more exchanges seaice_calc_viscosities (required
952        different loop boundaries in seaice_lsr and seaice_ocean_stress)
953      - bug fix in seaice_ocean_stress (update of lab_sea required)
954      - reduce loop boundaries to necessary minimum also in seaice_evp
955      - go back to the old way of computing deltaC/Z as the adjoint likes that
956        better
957    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
958      passive tracer to an Age Tracer) + update output.txt
959    o pkg/exf:
960      - implement A-grid / C-grid selection for wind-stress input files.
961      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
962      for now, in exf_bulk_largeyeager04.F only :
963      - change implementation for case where windspeed + 2. components wind-stress
964        are read-in. AND use rhoConstFresh to convert evap.
965    o pkg/seaice:
966      - use correct EXCH_UV for wind-forcing (on A-grid).
967      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
968        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
969    o pkg/exf:
970      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
971      EXF_INTERPOLATION:
972      - merge global_with_exf/code version of exf_interp_read.F
973        to the main code ;
974      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
975        reading the file ; Important: This options needs to be defined to recover
976        previous code.
977        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
978      - no longer loose real*8 precision along the way when using exf_iprec=64.
979    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
980      - change discretisation of evp-solver in order to avoid another exchange
981        (changes lab_sea) and clean up a little
982      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
983        help the adjoint (this also changes the results slightly)
984      - add a few "_d 0" where they had been missing in seaice_evp.F
985      - cleaning up: remove unused seaice_calc_rhs.F
986    o pkg/exf: some cleaning-up:
987      - change various "constants" into runtime parameters
988      - cleaned-up Large&Yeager04 routine which should eventually
989        replace exf_bulkformulae.F (changed names of S/R and CPP)
990        and merged various ALLOW_ATM_WIND options
991     only used with thsice pkg (in thsice_get_exf.F):
992      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
993        which are used when useStabilityFct_overIce=TRUE (= the default)
994      - change default values of ice & snow emissivity and scale downward LW
995        by ice & snow emissivity.
996    o pkg/thsice:
997     fix few little problems, in thsice_calc_thickn.F:
998      - growth vertically (and not laterally) if iceFrac == iceMaskMax
999      - melt only laterally if hIce < hThinIce (as the comments say)
1000      and in thsice_extend.F:
1001      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1002      - start to form ice as soon as the minimum ice-volume is reachable.
1003     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1004      and cpl_aim+ocn
1005    o pkg/kpp
1006     - move computation of surface related input fields to KPP into a new
1007       subroutine kpp_forcing_surf.F
1008     - remove wrong (within bi,bj loops) EXCH calls.
1009     - little cleaning (add argument myThid in last position, cvs header ...)
1010     - for now, fix conservation problem by exchanging KPPviscAz (may not
1011       be the best fix)
1012    o pkg/seaice
1013     - check for inconsistent evp parameter/cpp-flag combination
1014     - remove leftover errIO flat for obsolete name list error handling
1015    o OpenAD
1016     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1017    
1018    checkpoint59a
1019    o pkg/seaice: some parameter clarifications and a little bit of clean up
1020    o pkg/thsice: rename run-time parameters:
1021       himin       -> hIceMin
1022       himin0      -> hThinIce
1023       hihig       -> hThickIce
1024       i0          -> i0swFrac
1025       transCoef   -> bMeltCoef
1026       frac_energy -> fracMelting
1027      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1028       with default values (for now) that do not change the results.
1029      remove old version of thsice vars advection in pkg/seaice.
1030    o in FFIELDS.h:
1031      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1032      - make pLoad & sIceLoad always available (but still only used if
1033         ATMOSPHERIC_LOADING is #define).
1034    o pkg/kpp: replaced _KPP_RL with _RL
1035    o bug fixes for vertical diffusivity computations when both KPP and
1036        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1037        are no longer updating the vertical diffusivity array
1038        (passed as argument) but are (re-) setting those arrays.
1039    o pkg/seaice: fix bug in evp solver, while doing that
1040      - change (improve?) discretization of stress computations for both
1041        cgrid-lsr and evp solver
1042      - add a new routine to compute strain rates
1043      - the above changes lab_sea results
1044      - add no slip conditions for evp solver (off by default), lsr-version
1045        may follow
1046      - fix exchange for shear at Z-points (does not change lab_sea)
1047      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1048        (to force the user to pick a time step since there is not "safe" way
1049        of choosing it)
1050      - add principal stress diagnostics
1051      - rearrange fields for evp a little to avoid having to call a: too many
1052        exchanges and b: exchanges for stress trensor components which we do
1053        not have.
1054      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1055        of evp, complete rewrite for lsr case (latter is does not yet work
1056        in all cases)
1057    o pkg/kpp: add code to have mixing in shelf ice caverns
1058      - add myThid to all kpp routines (long overdue)
1059    
1060    checkpoint59
1061    o pkg/exf:
1062      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1063        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1064      - move exf header files from lower_case.h to UPPER_CASE.h ;
1065        add missing cvs Header & Name
1066      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1067      - add namelist param. selectStressGridPosition, exf_monFreq
1068      - retire many _CLIM routines, and remove data.exf_clim
1069        + params moved to data.exf
1070        + climsst, climsss now handled by exf_set_gen, i.e.
1071          climss?period=0 refers to constant field,
1072          climss?period=-12 to monthly forcing
1073      - split up namelists in data.exf
1074    o pkg/seaice:
1075      - remove seaice_exch and seaice_exch_uv
1076      - remove superfluous exchange of theta
1077      - add myThid to seaice_budget_ocean/ice
1078      - add new interface for atmospheric wind forcing (C-grid only)
1079        + new routine
1080        + two new field (taux, tauy for stress over ice)
1081        + removed one global field (DAIRN) for C-grid case only
1082    o pkg/thsise
1083      - 2nd set of modifs for thsice adjoint in conjunction with exf
1084    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1085    
1086    checkpoint58y_post
1087    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1088      vertical diffusivity, similar to that in MOM4; turned on using
1089      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1090      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1091    o Added capability for 3D specification of background vertical diffusion
1092      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1093      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1094      "data" file that contains the 3D vertical diffusivity coefficients.
1095    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1096      - add code within pkg thsice to advect & diffuse sea-ice fields
1097      similar to (and will replace) what has been added in  seaice_advdiff.F,
1098      but: - conserving Mass, Heat & Salt.
1099           - better when using non-linear advection scheme (not yet fully tested)
1100           - can also be used in atmospheric set-up (for now, only the diffusion).
1101    
1102    checkpoint58x_post
1103    o IO option for global-file compact format:
1104      - add options when generating topology (utils/exch2/matlab-topology-generator)
1105      - add I/O capability (pkg/mdsio).
1106      - adapt utils/matlab/rdmds.m to read this format.
1107      for now long-line format not yet supported by pkg/mdsio (& exch2).
1108    o shelfice: add a few diagnostics
1109    
1110    checkpoint58w_post
1111    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1112      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1113      (and replace horiVertRatio in NH code).
1114      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1115                         and tutorial_plume_on_slope (sensitive to truncation)
1116    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1117      directly to drive seaice model (C-grid only)
1118    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1119     - reintroduce computation of wind from stress,
1120     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1121       mass points to avoid tau = 0
1122     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1123    o rdmnc.m: make it work with "global" files created with gluemnc
1124    o rdmnc.m : some improvements in dealing with singleton dimension
1125      (tested on all testreport mnc output files).
1126    o genmake2: disable pkg/profiles if netcdf test fails.
1127    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1128    o move call to cal_readparms up to make calendar parameters/variable available
1129      to all packages
1130    
1131    checkpoint58v_post
1132    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1133      useDynP_inEos_Zc tested.
1134  o pkg/exf: changes to properly interpolate/mask/scale initial fields  o pkg/exf: changes to properly interpolate/mask/scale initial fields
1135  o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields  o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
