4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o pkg/obcs/exf
8  o moved ptracer ctrl index 17 -> 32    - obcs_precribe_read.F: change if statements so that they match
9                              the variable type (_RL)
10      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
11        exf_iprec) as part of namelist EXF_NML_01
12    o pkg/mdsio:
13      - read/write tiled (local) files: read/write 1-level tile chunk at a time
14        (instead of segment of length sNx); expected to speed up tiled IO.
15    o pkg/exch2:
16      - take buffer copy from/to array out of S/R exch2_send/recv into new
17        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
18        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
19      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
20      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
21        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
22        including Topology header file (and common blocks).
23      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
24        remove 2nd exch call in exch2_s3d_rx (no longer needed).
25      - document S/R arg. list (+ update some comments)
26    o pkg/seaice:
27      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
28        of LSR (this change is expected to change the results slightly because now
29        it uses slightly difference moduli from the second last LSR solution, but
30        that is more consistent with the stress computations; this part of the code
31        is not tested in the verification experiments)
32      - fix diagnostics for flux of ice in case of B-grid
33      - turn strain rates eij and press into global fields within global
34        common block in SEAICE.h for more straighforward diagnostics
35      - fix diagnostics for principal stress components, press, zeta, eta
36        to give something meaning full
37    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
38      new output (all 4 tests) using default rotationPeriod.
39    o pkg KPP:
40      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
41      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
42        and normal grid from 1 to Nr)
43    o Fix computations of L4rdt in mom_calc_visc.F
44    o eesupp:
45      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
46      should be called before a "stop" if we know that all process are going
47      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
48    
49    checkpoint61o
50    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
51    o model/src/ini_curvilinear_grid.F:
52       compute angleSin/CosC when they are not read from a file
53    o pkg/seaice:
54       add pseudo time stepping for LSOR
55    o pkg/exch2:
56       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
57    o pkg/seaice:
58       Adding separate sea ice albedo, drag coefficients, and HO in Southern
59       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
60    o SingleCpuIO:
61       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
62    o pkg/seaice:
63       put exchanged variable in (local) common block for MPI+Multi-Threads
64       to work (necessary with exch1, and for now with exch2 too).
65    o verification: to get more experiments tested with mpi, mth and mpi+mth,
66      change tiling of:
67       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
68       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
69      update output of exp:
70       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
71       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
72      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
73                       (note: output.txt generated on faulks using only 1 tile)
74    o eesupp & mdsio (SingleCpuIO):
75     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
76       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
77       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
78     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
79     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
80       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
81    o pkg/exch2:
82     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
83       read parameter file "data.exch2" if it exists; otherwise try default regular
84       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
85     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
86       with new code (not to be used, just as a backup solution).
87     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
88       in utils/exch2/input.
89    
90    checkpoint61n
91    o eesupp & mdsio (SingleCpuIO):
92      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
93        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
94        receive real*4 array (instead of real*8) to read/write 32.bit files.
95        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
96         and remove new mapping S/R)
97    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
98      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
99        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
100        when using exch2. Add S/R to map global io-buffer to global model array.
101      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
102    
103    checkpoint61m
104    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
105      and add 3 other S/R for other types (R4,R8,RS).
106      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
107    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
108     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
109     - reduce number of macro definitions (keep only those which are used);
110       can always call directly the corrresponding S/R if needed.
111     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
112       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
113     Fixed wrong type of arg in:
114       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
115       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
116     To fix: global_sum of var in common block is wrong (multi-threaded) in:
117       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
118     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
119    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
120      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
121    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
122    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
123      edges are closed (zero depth); might happen with "blank tiles";
124      for now, disabled if using OBCS.
125    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
126      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
127    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
128      to reduce length of 1.D array print in STDOUT.
129    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
130      + use 48 tiles (16x8): this will allow to test "blank tiles".
131    o start to test MPI + multi-threaded (change testreport to skip tests
132      where number of tiles do not match).
133    o genmake2: add option "-omp" to turn on Open-MP ;
134      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
135    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
136      and keep the original tile numbering. Note: compatible with old
137      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
138    
139    checkpoint61l
140    o Overlaps had been forgotten in calculating ijk keys : fixed
141    o fix cyrus makedepend for gcc 4.4
142    o experiment fizhi-cs-aqualev20:
143      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
144      and generate new output. Note: new output is much closer to the old
145      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
146      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
147    o pkg/fizhi:
148     - change to avoid indices going deliberately over array-bounds
149     - remove unnecessary MPI stuff
150     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
151     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
152       does not go over array-bounds and therefore returns reliable output.
153     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
154       this S/R has 4 output arguments, which are used inside "get_alarm";
155       when it is called with the same variable "ndum" in place of several
156       output arguments, this produces weird side effect inside "get_alarm"
157      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
158       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
159       address) and produces error.
160    o tools/gemake2: (March 27-29 2009)
161      with option "-mpi": link *_mpi files from "MODS" dir (this is what
162      testreport does).
163    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
164    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
165       update lab_sea.lsr & lab_sea.salt_plume results
166    o pkg/seaice:
167      Major overhaul of the LSOR solver: change discretization from original
168      finite differences to finite volume. The old routine is still in the
169      file seaice_lsr.F and can be turned on with the CPP-flag
170      SEAICE_OLD_AND_BAD_DISCRETIZATION
171      Along with this change, the discretization of the strain rates is changed.
172      The same flag turns on the old discretization in seaice_calc_strainrates.F
173      All verification experiments with seaice are affected (except for
174      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
175      results by setting the above flag.
176      Further changes involve changes in defaults:
177      - ALLOW_FLOODING is defined and turned on by default
178      - SEAICEadvSnow = .true. is now the default
179      - SEAICEadvSalt = .true. is now the default
180      - SEAICEadvAge  = .true. is now the default
181      - SEAICE_clipVelocities  = .false. is now the default
182                                         (as per J. Zhang's recommendation)
183      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
184        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
185      - seaice_growth: replace computation of UG by a simple copy from wspeed
186    
187    checkpoint61k
188    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
189      seaice_lsr: fixed a few metric terms,
190                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
191                  add more debugging diagnostics
192      seaice_evp: removed superfluous many metric terms of FV discretization
193                  of stress divergence
194                  affects lab_sea, lab_sea.hb87
195      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
196                  of stress divergence for non-evp solver
197                  (this part is not tested anywhere)
198      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
199                  they were effectively only half slip
200                  affects lab_sea.hb87
201      updated all relevant verification experiments (except lab_sea//output_adm.txt
202        which was left over, but fails at level 7 & 6)
203    
204    checkpoint61j
205    o pkg/seaice: turn a few hard wired parameters into run time parameters
206    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
207      time in seconds as promised by the usints in seaice_monitor and exf_monitor
208    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
209      that are not cubed-sphere grids
210    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
211    o pkg/ctrl:
212      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
213    o non-hydrostatic (calc_gw.F):
214      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
215      update output of exp. global_ocean.cs32x15.viscA4
216    o remove backward compatibility for thetaMin,phiMin
217      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
218    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
219      interpolated wind field not only for curvilineargrid=.true., but also
220      for a rotated grid (rotateGrid=.true.)
221    o pkg/exf: add capability to bypass interpolation for runoff
222      by setting yet another CPP-flag
223    o eesupp/src, B-grid exchange:
224      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
225    o autodiff
226      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
227      allows to switch to single-prec common blocks;
228      corresponding switch occurs in tamc.h, integer isbyte
229      TAF store directivs "byte" and "kind" seem equivalent;
230      Most tamc.h have been updated correspondingly.
231    
232    checkpoint61i
233    o autodiff:
234      fix autodiff_sore/_restore indices for obcs
235      (spotted by I. Hoteit, M. Mazloff)
236    o pkg/autodiff, pkg/ctrl:
237      Add flag to reduce all tapelev I/O to single-prec.
238      In data.ctrl set
239        doSinglePrecTapelev = .TRUE.
240    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
241      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
242    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
243      real fresh water flux (not yet)
244    o pkg/mdsio & rw:
245     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
246     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
247    o pkg/flt:
248     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
249       init_fixed & ini_varia.
250     - clean-up & simplify linear interpolation S/R:
251       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
252     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
253     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
254     - add vert. coordinate & horiz. indices to output files.
255     - change vertical position in initial condition, from index to depth [m].
256     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
257       (easier to get to a curvilinear grid) ; delX,delY no longer used.
258    o pkg/ggl90: a few modifications:
259     - fix bottom boundary condition, and interpolation of KappaE
260       near top and bottom
261     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
262     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
263     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
264    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
265      (maintain temporary backward compatibility, until next checkpoint)
266    
267    checkpoint61h
268    o pkg/diagnostics with "periodic averaging diagnostics":
269      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
270    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
271    o pkg/obcs: fix loop ranges for balancing code
272    o pkg/flt:
273     - improve criteria for finding which tile owns a float.
274     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
275    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
276      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
277      with ocean biogeo)
278    o pkg/flt:
279     - do some cleaning and fix the restart ;
280     - add output.txt in flt_example/results to get this pkg tested.
281    o genmake2: add an EXTENDED_SRC option and flag.
282       for now, cannot be turned on on command line (only through genmake_local)
283    o pkg/mdsio: read/write vector:
284     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
285     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
286       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
287     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
288      (drop to 4 digits matching for grad). But this test does not look very
289      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
290    
291    checkpoint61g
292    o pkg/flt:
293      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
294       + make OPTIONS file more standard.
295      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
296      - fix _BYTESWAPIO CPP-Flag
297      - standard reading of file-parameter "data.flt"
298      - fix argument list of S/R FLT_RESTART
299      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
300    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
301    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
302      a still unfixed compiler/optimization bug
303    
304    checkpoint61f
305    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
306      update results of global_ocean.cs32x15.icedyn test.
307    o move getcon.F from model/src to pkg/fizhi.
308    o pkg/exf: add parameter for extrapolation of temp up to the surface
309       and option to prevent negative evap (in bulk_largeyeager04 only).
310    o Prather Advection scheme: fix tracer conservation for divergent flow
311      (e.g., when using NonLin Free-Surface).
312    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
313    o gmredi (Visbeck-variable-K):
314     - add more parameters to Visbeck-variable-K.
315     - use a 5 points average for dSigmaR in Visbeck-K calculation
316       (more "homogenous": same stencil and same weights as in dSigmaH)
317     - update output of ideal_2D_oce experiment.
318    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
319      (#undef REAL4_IS_SLOW)
320     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
321       coordinate variable
322     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
323       (surface forcing fields), removes some of the functionality
324     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
325     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
326       probably not all: copy _RS surface flux fields to RL field before
327       calling DIAGNOSTICS_FILL
328     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
329       real*4 (CALL EXCH_*_RS) versions.
330     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
331       (generate new output).
332    
333    checkpoint61e
334    o gmredi (Visbeck-variable-K):
335      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
336      - change computation of Visbeck-K where Slope > Smax :        
337        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
338        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
339    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
340      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
341    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
342    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
343      does not become too large (to avoid precision problems in implicit-diffusion
344      solver); update ideal_2D_oce output.
345    o pkg ggl90:
346      - in ggl90_cal.F: compute only one set of visc/diff, used to
347        step forward TKE/T/S/momentum
348      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
349        have Prandlt =1)
350    o gmredi (fm07):
351      - add lower limit on Transition layer thickness + lower limit on 1/lambda
352      - allow to set few more params from data.gmredi
353    o pkg ggl90:
354          - add missing sqrt(2) factor in computation of mixing length
355            scale in ggl90_calc.F
356            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
357    
358    checkpoint61d
359    o adjoint modifs
360      - adapt to new field rhoInSitu
361      - allow to revert from StoreDynVars2D, StoreDynVars3D
362        to individual fields
363        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
364    o store 3-D (in-situ) density in commom block (DYNVARS.h)
365     - save 1 rho computation.
366     - no longer modify T & S inland when using down_slope pkg.
367    o gad_som : allow to switch to SOM advection for T & S without corresponding
368      pickup files (using new S/R: MDS_CHECK4FILE).
369    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
370      (for useSingleCpuIO to work in multi-threaded)
371    o pkg/shelfice:
372     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
373       with SHELFICEtopoFile in data.shelfice
374     - move code for reading ice shelf topography and modifying hFacC into separate
375       subroutines of the shelfice package
376     - separate initialisation of "fixed" and "variable" variables
377     - kTopC is not (yet) replaced by kSurfC, although this is possible
378    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
379    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
380      and rename:
381      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
382      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
383    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
384    
385    checkpoint61c
386    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
387      to add mass source/sink of fluid in the interior (3-D generalisation
388      of oceanic real-fresh water flux).
389    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
390    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
391    o new pkg: down_slope
392      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
393      - presently, modify T & S inland (dwnslp_calc_rho.F).
394        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
395      - implementation for ocean in P-coords not tested.
396      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
397    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
398      (to facilitate conversion of oceanic pkg to p-coordinate).
399    o change FIND_RHO to FIND_RHO_2D :
400      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
401    o new pkg: cheapaml
402    
403    checkpoint61b
404    o exch2:
405      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
406      - no longer depend on the order sequence (N,S,E,W).
407      - 3rd exchange no longer needed (tested with 24 tiles).
408      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
409      - exch_UV_A-grid readily available (but not yet tested).
410      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
411      (both are no longer needed) in exch_uv: no effect in forward run; but
412       get truncation error differences with adjoint exch.
413    o exch2:
414     - change index-bounds storage (moved from target to local tile,
415       more intuitive this way) ; rename/remove some variables.
416     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
417    
418    checkpoint61a
419    o exch2/matlab-topology-generator:
420      fix bug in index bounds for N-S internal exchange (hard to tell if this
421      had any effect on the solution).
422    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
423      is exceeded
424    o testreport: modify syntax of awk, so that it works also with
425      awk, and not only with nawk and gawk
426    
427    checkpoint61
428    o autodiff
429      Change default for TAF usage by removing argument '-nonew_arg'
430      This changes TAF subroutine argument list (ordering of active var.)
431      Omission of this flag leads to incompatibility w.r.t. TAMC
432      To restore TAMC-compatibility, need following modifs:
433      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
434      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
435      Tested TAF version is 1.9.22
436      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
437    
438    checkpoint60
439    --->>> This is the last checkpoint for which generating the adjoint
440    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
441    --->>> by default.
442    --->>> Future checkpoints will ommit this flag by default.
443    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
444    o pkg/grdchk: Add gradient check to etan0 perturbations.
445    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
446    o pkg/autodiff: more flexibility in zeroadj.
447      model/src: modifying do_oceanic_phys.F accordingly.
448    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
449    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
450      special setup of gmredi for which the adjoint is stable
451      enough for parameter optimization.
452    o bridging the gap between eddy stress and GM.
453      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
454          along with a change in CPP option (now ALLOW_EDDYPSI).
455      -> when using GM w/ GM_AdvForm:
456          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
457          is applied either in the tracer Eq. or in momentum Eq.
458          depending on data.gmredi (intro. GM_InMomAsStress).
459      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
460      The key modifications are in model/src/taueddy_external_forcing.F
461      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
462    
463    checkpoint59r
464    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
465      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
466      fix option to read coriolis(@ cell-corner) from files with CS-grid.
467    o pkg/mnc: add some attributes to standard 1D-coordinate variables
468    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
469      mass points, when using mnc for output
470      - add runtime parameter (missing_value, missing_value_int) to override
471        default (which is the value of getcon('UNDEF'))
472    o pkg/mnc: prepare mnc for the actual use of missing values with the
473      diagnostics package: small fix in mnc_cw_readwrite.template and more
474      initialisation of never used fields
475      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
476      versions
477    o pkg/thsice/thsice_ini_vars.F added default initial values so that
478      thermodynamics sea ice solver does not blow up when some initial fields
479      are missing.
480    o move from external_forcing_surf.F to ini_forcing.F
481      the p-coord. hack consisting in using pLoad to set phi0surf ;
482      update output of tutorial_global_oce_in_p (affected @ truncation level).
483    o Freshen up a bit hs94.1x64x5, notably:
484      remove rotationPeriod and tRef=5*0. (adjoint only), and add
485      exactConserv=.TRUE.
486    o pkg/generic_advdiff:
487      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
488      applies to files where Temperature & Salinity 2nd Order moments are used.
489    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
490      this uses a dynamically allocated internal state data structure
491      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
492      and requires a fortran 90 compiler
493    
494    checkpoint59q
495    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
496       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
497    o Refresh tutorial_global_oce_biogeo, notably:
498      - change bathymetry (put back seamounts in ACC, use hFacs)
499      - change EOS (POLY3 --> JMD95Z)
500      - use Bryan-Lewis vertical diffusivity
501      - use multidimensional advection
502      - remove old virtual virtual in dic pkg, now done through ptracer pkg
503      - change a couple of parameters in dic pkg
504    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
505    o pkg/obcs: change default to OBCSfixTopo = .true.,
506      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
507      - replace "debugMode" with "debugLevel .GE. debLevB"
508    o implementation of TAF directives for gchem,cfc,dic
509    o remove "exp5" (replaced by tutorial_deep_convection).
510    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
511      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
512      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
513      --> changes results in exp4, seaice_obcs
514    o tutorial_deep_convection :
515      update the set-up and increase resolution and domain size ; start
516      from pseudo initial conditions = output at t=120mn in order to see
517      something happening when running testreport.
518    o pkg/seaice: add os7mp as an advection scheme
519                  add check for advection schemes
520                  add a flag for restoring T and S underneath sea ice
521    o pkg/my82: add netcdf-support and diagnostics
522    o thsice pkg:
523      - Now hsMax limits snow height by turning it into ice following
524        flooding scheme (and now conserving energy)
525      - Slight rewriting of the formula in thsice_calc_thick.F
526      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
527      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
528    
529    checkpoint59p
530    o gchem / dic / cfc :
531      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
532      - add new parameter files: "data.dic" & "data.cfc" ;
533      - various re-arrangement in initialisation & header file ;
534      - fix tutorial_global_oce_biogeo for multi-threaded test.
535    o pkg/dic: test for "pickup_dic" file when restarting ;
536      if no pickup-file, can restart with a re-initialised pH (same as it did
537      before) providing pickupStrictlyMatch is set to False.
538    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
539      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
540    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
541      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
542    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
543     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
544       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
545    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
546       scheme to use for vorticty-term ;
547     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
548       (with default selectVortScheme, return to original discretisation)
549     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
550    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
551    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
552      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
553      also fix diagnostics VISCAHW & VISCA4W.
554    
555    checkpoint59o
556    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
557    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
558      move a few statemens out the main loop into separate loops
559    o pkg/shelfice:
560      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
561        (kg/m^2/s), does not break tests, because in verification/isomip,
562        rhoConstFresh=rhoConst (by accident)
563      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
564      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
565        new file model/src/seawater.F, so that they are available for all pkgs.
566      - convert potential temperature into in-situ temperature. This changes the
567        isomip tests => update tests
568    o add a flag writePickupAtEnd (default=true) to be able to suppress
569      writing a pickup at the last timestep
570    o tools/mpack-1.6 :
571      - disable automake (not working) and autoconf (not needed).
572      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
573        also cleaner with much less compilation warnings.
574    o pkg/profiles:
575      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
576      (for "less than 32 characters name" compiler requirement)
577    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
578      conditions that have a different sampling frequency than S/T/U/V obcs
579    o pkg/diagnostics (stats-diags):
580      - fix global Min/Max in case 1 processor get only empty tiles
581    o genmake2: replace (4 times)
582         make genmake_tc_1.o >> genmake_warnings 2>&1
583      with
584         COMM="$CC $CFLAGS -c genmake_tc_1.c"
585         echo $COMM >> genmake_warnings
586         $COMM >> genmake_warnings 2>&1
587      to make genmake2 always see the value of CC as specified in the optfile.
588    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
589      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
590      - modify verification advect_cs test to test SOM-advection on CS-grid.
591    o pkg/ctrl:
592      - Rewrite of ctrl_map_ini_ecco.F,
593        introducing a generic routine (ctrl_map_ini_gen.F).
594      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
595    
596    checkpoint59n
597    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
598      number in dedicate array "hdiag":
599      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
600        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
601      - many small changes (integer format) for large number of diagnostics
602      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
603        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
604    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
605      usingSphericalGrid, this allows to define the rotated grid coordinates
606      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
607      geographical coordinates according to the inverse of the rotation defined
608      by the Euler angles, so that Coriolis parameter and online-interpolation by
609      exf works with the geographical coordinates on XC/YC/XG/YG.
610      Naturally, this feature does not work with all packages, so some
611      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
612      profiles), because there the coordinates are assumed to be regular
613      spherical grid coordinates.
614    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
615      - introduce isopycnal diffusion coefficient control.
616    o tools/adjoint_options:
617      - additional control vector components.
618    o pkg/mnc: have mnc create marginally meaning full coordinate variables
619      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
620    o pkg/mypackage:
621      - add example of read/write pickup for state-var ;
622      - add entry points to the main code for state-vars diags & write-pickup.
623    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
624      transitions for useExfYearlyFields
625      - add new subroutine that determines the file to read from for
626        use*YearlyFields = .TRUE. and .FALSE.
627      - add a verification experiment to global_with_exf that tests
628        useExfYearlyFields with USE_EXF_INTERPOLATION defined
629    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
630      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
631      subroutines (which could be generated from a template, because they are
632      almost identical), for now they are included in obcs_prescribe_read.F for
633      simplicity
634    o pkg/exf:
635      - add a little more diagnostic to exf_interp_read (in analogy to
636        mds_read_field, can be turned off with debugLevel < debugLevA=1)
637      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
638        ugly but fast by unrolling short inner loops, inserting a unroll=8
639        directive in routine lagran, and splitting a loop and making do while the
640        outermost loop (the latter requires the intoduction of index arrays)
641    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
642    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
643      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
644    o verification/seaice_obcs: updated for restart test and latest options
645    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
646      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
647      for now this is only available for the C-grid code and also within
648      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
649    
650    checkpoint59m
651    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
652      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
653    o gad_som : fix flux output (& diagnostics) to have same units as other  
654      advection scheme fluxes (was previously multiplied by deltaT).  
655    o added verification/seaice_obcs both to test seaice open boundaries
656      and to provide an example matlab scrpt for generating them
657    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
658    o pkg/salt_plume: clean up salt_plume_frac.F to
659      remove redundancy in PlumeMethod 1 and 4
660    o pkg/kpp: added saltplume diagnostics
661    o pkg/obcs and pkg/seaice:
662      - do not set uice and vice to zero when OB*icefile are unspecified
663      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
664      - moved seaice tracer obcs after call to seaice_growth
665    o pkg/salt_plume: added various options for salt plume depth
666      criterion and for vertical distribution of the salt
667    
668    checkpoint59l
669    o pkg/ptracers: new version of ptracers pickup:
670      read meta file and write only fields which are needed to restart.
671      ( same logic as main pickup file ; also using pickupStrictlyMatch )
672    o pkg/seaice:
673      - add timescale for melting due to warm mixed layer as a means of
674        setting SEAICE_availHeatFrac more conveniently
675      - add a CPP-flag/runtime parameter check for flooding algorithm
676      - reformulated availHeat in seaice_growth.F to be independent of AREA
677    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
678      unit changes
679    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
680    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
681      SX vector computer.
682    o pkg/seaice:
683      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
684        seaice forcing fields can now be read only through pkg/exf
685      - removed some unused halos
686    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
687    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
688      or U/VICE from U/VWIND before computing U/VSTRESS
689    
690    checkpoint59k
691    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
692      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
693    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
694      all experiments pass when compile with un-initialised var. checking option.
695    o added pkg/salt_plume
696    o script to test restart (for now, in MITgcm_contrib/jmc_script)
697    o pkg/seaice: new read/write pickup version.
698      read meta file and write only fields which are needed to restart.
699      ( same logic as main pickup file ; also using pickupStrictlyMatch )
700    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
701    o lab_sea.hb87: modify the domain & update output.hb87.txt :
702      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
703      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
704      process. Fixed here by closing the domain at the Northern boundary.
705    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
706    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
707      a set of consecutive levels in/from a 3-D array.
708    o pkg/ptracers:
709      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
710      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
711    
712    checkpoint59j
713    o in pkgs: dic, obcs, offline, rbcs:
714      standard way to compute coeff. for time interpolation between 2 time reccords
715      which retains full precision (& make results less dependent on compiler).
716      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
717    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
718      packages instead of reading ice cover and wind speed separately
719    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
720     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
721      to allow to compile customized code before the update)
722    o cleaning-up:
723      - fix CPP instruction syntax in pkg/obcs
724      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
725        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
726      - fix some threads issue in IO parts.
727    o pkg/dic:
728      - add tons of "_d 0" (--> much better testreports !)
729       and then update outputs of tutorial_global_oce_biogeo
730    o pkg/mom_fluxform:
731      add a special version of momentum advection intended to conserve momentum
732      next to a bathymetry step or a coastline edge. (default = off = #undef)
733    o new read/write pickup version:
734      - for now, only implemented for main (mdsio) pickup file.
735      - write out only what is needed to restart; merge pickup_nh , pickup_ph
736        and main pickup together.
737      - read meta file; read only what is needed to restart; stop if a field
738        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
739        if it make sense (even if the restart is not perfect).
740      - if no meta file, assume that pickup to read corresponds exactly to
741        a pickup that would currently be written.
742      - read pickup written in the old format (until checkpoint59i) if it
743        recognizes an old meta file (no field-list).
744      - add a meta file in exp. which starts from a pickup: 2 cases:
745        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
746         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
747        b) a meta file describing the content of the associated pickup file
748         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
749    o pkg/mdsio & pkg/rw:
750      - new routine to read a meta file ; new set of routine to read
751        Multiple-fields file (with meta file).
752    o added open boundary conditions capability for seaice
753        HSNOW, HSALT, UICE, and VICE
754    
755    checkpoint59i
756    o adjoint:
757      * fix multiDimAdvection adjoint
758        (partial recomputation problem by TAF for fVerT(:,:,kDown)
759        and comlev1 size definition (maxpass vs. max. number of tracers)
760      * verification/global_ocean.90x45x15 adjoint now tests
761        NLFS and multiDimAdvection using DST3 (=30)
762      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
763    o pkg/kpp: add "_d 0" to real constant (if missing);
764      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
765      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
766    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
767      for internal parameters related to restart process (formerly from PARAMS.h)
768      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
769    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
770      as argument. (only atm2d & obcs write_pickup have not yet been updated)
771    o pkg/monitor:
772      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
773      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
774      - account for deep Atmosphere factor and density factor (anelastic)
775    o added open boundary conditions capability for seaice HEFF and AREA
776    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
777      thermodynamics
778      - requires a little reorganization, which affects the testreport results
779        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
780        so that now the conservative form is tested
781      - add a few comments
782    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
783    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
784    o add new diagnostics to seaice: advective, diffusive fluxes (only for
785      multidim-advection, for scheme 2 they are not filled) and transports,
786      thermodynamic growth rates
787    o change units of EmPmR (inside the code, + within coupling interface)
788      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
789      Affects results @ truncation level (cg2d match) and update output of
790       experiments: lab_sea(6), global_ocean.90x40x15(10),
791      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
792      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
793      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
794      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
795    
796    checkpoint59h
797    o pkg/exf:
798      - improve vectorization by moving if-statement out of loops in
799        exf_mapfields, exf_radiation
800      - exf_bulkformulae.F: introduce 2D fields and vectorize code
801    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
802    o testreport:
803      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
804        monitor & update offline_exf_seaice exp. output.
805      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
806    o pkg/seaice:
807      - bug fix in the evp solver: boundary conditions were affected be
808        masking of zMax/zMin (changes results)
809      - minor bug fix in boundary conditions in seaice_calc_strainrates
810        (changes results for no_slip)
811      - seaice_lsr.F: make interpolation of eta dependent on boundaries
812      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
813      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
814        stress formulation and no-slip boundary conditions
815    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
816      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
817    o pkg/seaice: a first HSALT time stepping equation has been checked in
818    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
819      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
820      without requiring DO-IF statements
821    o pkg/thsice:
822      use continuous power-law function for partition of energy between lateral
823      melting/freezing and thinning/thickening ; old code using step function
824      still available with #undef THSICE_FRACEN_POWERLAW
825      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
826    o testreport: change AD testing : check against results/output_adm.txt
827      using same scripts as for forward test.
828    
829    checkpoint59g
830    o adjoint testing: in preparation for changing testreport:
831      - output format: cost and grad written on separated lines
832      - ad output results in directory "results" (instead of "results_ad")
833    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
834    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
835    o pkg/ecco: allow user defined cost function contributions
836    o testreport:
837      Allow to choose (per experiment) the list of tested output variables
838       and the main variable (used to issue a pass/FAIL ) ;
839      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
840      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
841      Also modify printing of summary:
842       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
843       b) echo the list of tested variables in the individual summary.txt of
844          each experiment.
845    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
846      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
847      (but still depend on the tile decompostion of the domain).
848    o pkg/seaice: change a discretization detail to make the B-grid code
849      "more symmetric". This change is likely to remove all "ridges/leads" that
850      where quasi-aligned with the grid in B-grid solutions. It may also be
851      the solution to the stress coupling issues with the B-grid.
852    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
853      remove .cvsignore from input dir. (since testreport no longer run here).
854    o pkg/thsice:
855     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
856     - fix reshaping of sea-ice just after advection:
857       melt all the ice only if ice-volume is too small.
858     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
859       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
860     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
861    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
862      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
863    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
864      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
865      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
866      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
867      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
868      -> update output.txt
869    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
870     this affects truncation error: -> update output.txt of exp:
871      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
872      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
873    
874    checkpoint59f
875    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
876    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
877      a bounded range (in forward mode)
878    o pkg/ecco, ctrl, autodiff and mom_common:
879     internal parameter controls, completements of implementations
880    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
881    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
882      (not seem any difference in testing results).
883    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
884       at face corners.
885    o pkg/generic_advdiff:
886     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
887      loop range indices for computing vertical advection tendency
888      and do the calculation in the interior only (no overlap) ;
889      for now, only implemented for SOM advection (to save CPU time).
890     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
891    o exch2 adjoint
892      First set of changes:
893      - add exch2 hand-written adjoint templates
894      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
895        This will require cleanup in pkg/autodiff/*.F
896        (changed routines currently kept separate in verif. code/)
897      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
898        that used to hide exch2 or cubed-sphere specific code
899        (commented via 'cph-exch2')
900    o pkg/seaice
901      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
902    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
903       output of global_ocean.cs32x15.thsice .
904    
905    checkpoint59e
906    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
907      for B-grid vector (not yet tested) and C-grid vector (<- only used
908      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
909    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
910      (#ifdef ALLOW_SALT_PLUME)
911    o gather_2d/scatter_2d: removed halo regions
912    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
913      scheme and the corresponding test case (under front_relax dir). For now,
914      only available with Skew-flux form and not yet tested in realistic set-up.
915      adjoint: store directives updated, but gradient checks deteriorated,
916      so maybe GM/Redi adjoint is now broken.
917    o seaice adjoint
918      * add AREA, HEFF, HSNOW as control variable
919        (should not change lab_sea results)
920      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
921    o pkg/seaice:
922      * added computation of saltFlux in seaice_growth;
923        For time being, sea ice salinity is assumed constant
924        contribution of snow flooding to freshening of sea ice is neglected.
925        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
926        defaults to 0.0 in order to maintain backward compatibility.
927        Typical values for SEAICE_salinity are 4 to 10 g/kg.
928      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
929      * added SEAICE_availHeatFrac, which specifies fraction of surface level
930        heat content used to melt or grow ice
931      * commented out cap of HICE: it helps keep ice thinner
932      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
933      * applied OBCS T/S mask to HEFFM sea ice mask
934    
935    checkpoint59d
936    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
937     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
938     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
939    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
940     and change default value of parameter "GM_Small_Number";
941     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
942       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
943       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
944    o pkg/ecco: cost function when applying pkg/smooth to controls
945    o pkg/ctrl: add forcingPrecond run time parameter
946    o pkg/seaice:
947     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
948     - fix bug in metric terms of u-equation in LSR solver (implicit part),
949       changes verification/lab_sea
950     - rearrange implicit part of u-equation in LSR solver to make it easier to
951       read, understand, and debug. This causes changes at the truncation level.
952     - fix (serious) bug in the boundary conditions (sign error in the implicit
953       part) of the LSR solver. Changes all LSR results.
954     - fixed problem with HSNOW initialization to avoid thick snow when AREA
955       is initilized with small values - does not change lab_sea results.
956     - added HsnowFile initialization capability
957    o pkg/smooth: addition to model/src and pkg/ctrl so allow
958     initialization of pkg/smooth and application to control vector
959    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
960    o dependencies: pkg/profiles requires pkg/cal
961    o pkg/profiles:
962     - added option ALLOW_PROFILES_GENERICGRID
963         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
964         that interpolation information (grid points and coefficients) is provided
965         within the netcdf input files.
966         -> sample matlab scripts can be found in MITgcm_contrib/gael
967         that allow you to prepare netcdf input files.
968     - also modified: cleaner include statements, cleaner error print statements,
969       cleaner stops when error, and more tests of the netcdf input files consistency.
970    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
971    o pkg/seaice:
972     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
973       requires a new routine: seaice_diagnostics_fill.F
974     - make sure that seaice does not move if not forced (pressure replacement
975       method, Hibler and Ip, 1995), changes results
976     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
977     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
978       It is turned off by default (=-1.), because it changes the results.
979     - make it possible to read AREA from a file, too.
980    
981    checkpoint59c
982    o add S/R and diagnostics for oceanic mixed-layer depth
983    o move GMRedi call after all vertical mixing schemes (including KPP)
984    o pkg/thsice:
985     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
986      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
987    o pkg/obcs:
988     - bug fix for balance code
989    o pkg/seaice:
990      - allow values of SEAICE_elasticParm > 1
991      - add new parameter SEAICE_evpTauRelax as an alternative
992        to SEAICE_elasticParm
993      - make lsr boundary conditions free slip (by default), changes result
994      - add code for no slip boundary conditions for lsr
995      - set minimum of zeta to zero (and not 4e8) (changes results)
996      - add a cap on AREA after advecting AREA if seaice_growth is not called
997    o change calculation of Visbeck K:
998      - no longer depend on tapering scheme; instead, compute slope (limited
999        by GM_maxSlope). this is equivalent to what was comuted before with
1000        clipping or linear tappering.
1001      - fix vertical averaging (wrong by 1/2 level)
1002      - leave the old version (but will not be maintained) within
1003        #ifdef OLD_VISBECK_CALC / #endif
1004      - update output of exp. ideal_2D_oce
1005    o change error catch in calc_r_star to improve vectorization
1006    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1007      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1008    o adjoint:
1009      Re-organized adjoint checkpointing according to Matt Mazloff
1010      (but with modifs/completions/cleanups)
1011      Storing is now bundled into large arrays to optimized I/O
1012      (and second step in cleanup of the_main_loop)
1013    
1014    checkpoint59b
1015    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1016      - export/import (between ocean & coupler) fields needed for ocean DIC.
1017    o pkg/seaice:
1018      - get rid of three more exchanges seaice_calc_viscosities (required
1019        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1020      - bug fix in seaice_ocean_stress (update of lab_sea required)
1021      - reduce loop boundaries to necessary minimum also in seaice_evp
1022      - go back to the old way of computing deltaC/Z as the adjoint likes that
1023        better
1024    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1025      passive tracer to an Age Tracer) + update output.txt
1026    o pkg/exf:
1027      - implement A-grid / C-grid selection for wind-stress input files.
1028      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1029      for now, in exf_bulk_largeyeager04.F only :
1030      - change implementation for case where windspeed + 2. components wind-stress
1031        are read-in. AND use rhoConstFresh to convert evap.
1032    o pkg/seaice:
1033      - use correct EXCH_UV for wind-forcing (on A-grid).
1034      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1035        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1036    o pkg/exf:
1037      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1038      EXF_INTERPOLATION:
1039      - merge global_with_exf/code version of exf_interp_read.F
1040        to the main code ;
1041      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1042        reading the file ; Important: This options needs to be defined to recover
1043        previous code.
1044        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1045      - no longer loose real*8 precision along the way when using exf_iprec=64.
1046    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1047      - change discretisation of evp-solver in order to avoid another exchange
1048        (changes lab_sea) and clean up a little
1049      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1050        help the adjoint (this also changes the results slightly)
1051      - add a few "_d 0" where they had been missing in seaice_evp.F
1052      - cleaning up: remove unused seaice_calc_rhs.F
1053    o pkg/exf: some cleaning-up:
1054      - change various "constants" into runtime parameters
1055      - cleaned-up Large&Yeager04 routine which should eventually
1056        replace exf_bulkformulae.F (changed names of S/R and CPP)
1057        and merged various ALLOW_ATM_WIND options
1058     only used with thsice pkg (in thsice_get_exf.F):
1059      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1060        which are used when useStabilityFct_overIce=TRUE (= the default)
1061      - change default values of ice & snow emissivity and scale downward LW
1062        by ice & snow emissivity.
1063    o pkg/thsice:
1064     fix few little problems, in thsice_calc_thickn.F:
1065      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1066      - melt only laterally if hIce < hThinIce (as the comments say)
1067      and in thsice_extend.F:
1068      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1069      - start to form ice as soon as the minimum ice-volume is reachable.
1070     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1071      and cpl_aim+ocn
1072    o pkg/kpp
1073     - move computation of surface related input fields to KPP into a new
1074       subroutine kpp_forcing_surf.F
1075     - remove wrong (within bi,bj loops) EXCH calls.
1076     - little cleaning (add argument myThid in last position, cvs header ...)
1077     - for now, fix conservation problem by exchanging KPPviscAz (may not
1078       be the best fix)
1079    o pkg/seaice
1080     - check for inconsistent evp parameter/cpp-flag combination
1081     - remove leftover errIO flat for obsolete name list error handling
1082    o OpenAD
1083     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1084    
1085    checkpoint59a
1086    o pkg/seaice: some parameter clarifications and a little bit of clean up
1087    o pkg/thsice: rename run-time parameters:
1088       himin       -> hIceMin
1089       himin0      -> hThinIce
1090       hihig       -> hThickIce
1091       i0          -> i0swFrac
1092       transCoef   -> bMeltCoef
1093       frac_energy -> fracMelting
1094      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1095       with default values (for now) that do not change the results.
1096      remove old version of thsice vars advection in pkg/seaice.
1097    o in FFIELDS.h:
1098      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1099      - make pLoad & sIceLoad always available (but still only used if
1100         ATMOSPHERIC_LOADING is #define).
1101    o pkg/kpp: replaced _KPP_RL with _RL
1102    o bug fixes for vertical diffusivity computations when both KPP and
1103        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1104        are no longer updating the vertical diffusivity array
1105        (passed as argument) but are (re-) setting those arrays.
1106    o pkg/seaice: fix bug in evp solver, while doing that
1107      - change (improve?) discretization of stress computations for both
1108        cgrid-lsr and evp solver
1109      - add a new routine to compute strain rates
1110      - the above changes lab_sea results
1111      - add no slip conditions for evp solver (off by default), lsr-version
1112        may follow
1113      - fix exchange for shear at Z-points (does not change lab_sea)
1114      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1115        (to force the user to pick a time step since there is not "safe" way
1116        of choosing it)
1117      - add principal stress diagnostics
1118      - rearrange fields for evp a little to avoid having to call a: too many
1119        exchanges and b: exchanges for stress trensor components which we do
1120        not have.
1121      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1122        of evp, complete rewrite for lsr case (latter is does not yet work
1123        in all cases)
1124    o pkg/kpp: add code to have mixing in shelf ice caverns
1125      - add myThid to all kpp routines (long overdue)
1126    
1127    checkpoint59
1128    o pkg/exf:
1129      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1130        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1131      - move exf header files from lower_case.h to UPPER_CASE.h ;
1132        add missing cvs Header & Name
1133      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1134      - add namelist param. selectStressGridPosition, exf_monFreq
1135      - retire many _CLIM routines, and remove data.exf_clim
1136        + params moved to data.exf
1137        + climsst, climsss now handled by exf_set_gen, i.e.
1138          climss?period=0 refers to constant field,
1139          climss?period=-12 to monthly forcing
1140      - split up namelists in data.exf
1141    o pkg/seaice:
1142      - remove seaice_exch and seaice_exch_uv
1143      - remove superfluous exchange of theta
1144      - add myThid to seaice_budget_ocean/ice
1145      - add new interface for atmospheric wind forcing (C-grid only)
1146        + new routine
1147        + two new field (taux, tauy for stress over ice)
1148        + removed one global field (DAIRN) for C-grid case only
1149    o pkg/thsise
1150      - 2nd set of modifs for thsice adjoint in conjunction with exf
1151    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1152    
1153    checkpoint58y_post
1154    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1155      vertical diffusivity, similar to that in MOM4; turned on using
1156      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1157      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1158    o Added capability for 3D specification of background vertical diffusion
1159      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1160      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1161      "data" file that contains the 3D vertical diffusivity coefficients.
1162    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1163      - add code within pkg thsice to advect & diffuse sea-ice fields
1164      similar to (and will replace) what has been added in  seaice_advdiff.F,
1165      but: - conserving Mass, Heat & Salt.
1166           - better when using non-linear advection scheme (not yet fully tested)
1167           - can also be used in atmospheric set-up (for now, only the diffusion).
1168    
1169    checkpoint58x_post
1170    o IO option for global-file compact format:
1171      - add options when generating topology (utils/exch2/matlab-topology-generator)
1172      - add I/O capability (pkg/mdsio).
1173      - adapt utils/matlab/rdmds.m to read this format.
1174      for now long-line format not yet supported by pkg/mdsio (& exch2).
1175    o shelfice: add a few diagnostics
1176    
1177    checkpoint58w_post
1178    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1179      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1180      (and replace horiVertRatio in NH code).
1181      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1182                         and tutorial_plume_on_slope (sensitive to truncation)
1183    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1184      directly to drive seaice model (C-grid only)
1185    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1186     - reintroduce computation of wind from stress,
1187     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1188       mass points to avoid tau = 0
1189     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1190    o rdmnc.m: make it work with "global" files created with gluemnc
1191    o rdmnc.m : some improvements in dealing with singleton dimension
1192      (tested on all testreport mnc output files).
1193    o genmake2: disable pkg/profiles if netcdf test fails.
1194    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1195    o move call to cal_readparms up to make calendar parameters/variable available
1196      to all packages
1197    
1198    checkpoint58v_post
1199    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1200      useDynP_inEos_Zc tested.
1201    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1202    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1203      and portions thereof.  See read_cs.txt for description and examples.
1204    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1205      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1206      following the great-circle arc between those 2 points.
1207    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1208      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1209    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1210     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1211     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1212     - still needs work (not working with some options ; efficiency to improve)
1213       and serious testing.
1214     - use this scheme for temperature & salinity in 2 advection test exp.:
1215       advect_xy & advect_xz, respectively.
1216    
1217    checkpoint58u_post
1218    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1219    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1220    o testreport: add option "-skipdir" to skip some test.
1221    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1222      momentum calculation.
1223    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1224    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1225      remove checkpoint.F and the_correction_step.F (no longer used);
1226      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1227    o add option (linFSConserveTr) to correct for tracer source/sink due to
1228      Linear Free surface
1229    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1230    o pkg/thsice: fix reading mnc-pickups
1231    
1232    checkpoint58t_post
1233    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1234    o pkg/mdsio:
1235     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1236       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1237       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1238     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1239     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1240       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1241     - new S/R (to replace MDSWRITEMETA), which allows to write more
1242       informations (variable names, time ...) to meta files.
1243     - modify rdmds.m to give back the meta file content.
1244    o pkg/diagnostics: change vertical interpolation to be safer, and more
1245       flexible (define p-levels to interpolate to in data.diagnostics);
1246      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1247       diagnostic pointer.
1248    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1249    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1250    o fix multi-category seaice:
1251     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1252       SEAICE_MULTICATEGORY
1253     - fix short wave heat flux
1254    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1255       and allow to use EVP solver. Change forward lab_sea: test both EVP
1256       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1257    o Initial check-in of lab_sea adjoint
1258      (very similar to natl_box_adjoint/code_seaice)
1259      * used C-grid and EVP solver
1260      * used KPP, GM/Redi
1261      * uses inAdExact=.TRUE.
1262      * gradient checks fail for both ADM and TLM
1263        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1264        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1265        issue is related to forward mismatch between g77 an ifort
1266    o pkg/seaice: overhaul of thermodynamics
1267     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1268     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1269     - move a few global fields out of SEAICE.h into seaice_growth.F and
1270       make them 2D (FICE/QNETO/ ...)
1271     - remove FO (it is the same as QNETO)
1272     - introduce a few local fields to avoid modifying external fields such
1273       as atemp, etc.
1274    
1275    checkpoint58s_post
1276    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1277      changed exf_set_gen.F so that
1278        genperiod=0 means input file is one time-constant field and
1279        genperiod=-12 means input file contains 12 monthly means
1280    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1281      this affects truncation error ; generate new output file for exp. which
1282      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1283        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1284        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1285        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1286        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1287        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1288    o start implementation of deep-atmosphere and anelastic formulation
1289    o verification: remove 2nd copy of input files and use script "prepare_run"
1290      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1291    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1292    o profiles: fix for multithreaded case
1293    
1294    o diagnostics: rename few diags:
1295      s/'PRESSURE'/'RCENTER '/g
1296      s/'TICE    '/'oceFreez'/g
1297      s/'TAUX    '/'oceTAUX '/g
1298      s/'TAUY    '/'oceTAUY '/g
1299      s/'SWFLUX  '/'oceQsw  '/g
1300      s/DIFx/DFxE/g
1301      s/DIFy/DFyE/g
1302      and add few ocean-forcing diagnostics:
1303      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1304    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1305      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1306      as actual snow thickness.  It now refers everywhere to effective snow
1307      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1308    
1309    checkpoint58r_post
1310    o modifications to pkg/seaice/growth.F, which change results of
1311      lab_sea experiment: fixes pertain to melting snow over open water, to
1312      masking EVAP under sea ice, and to using the correct AREA variable for
1313      computations of EVAP, PRECIP, HSNOW, and GHEFF
1314    o add ability to read bathy, salt, and theta using MNC (off by def)
1315    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1316      both are turned off by default and do no change any results
1317    o seaice advection with pkg/thsice: a step toward the use of non-linear
1318      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1319    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1320      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1321      in natl_box (affects results @ truncation level: update output.txt)
1322    o multi-threading and IO:
1323      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1324      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1325        (needed to work with SingleCpuIO): tested in all verif. exp.
1326    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1327      affects the results (but none of the verification test uses this scheme).
1328    o Adding some pkg/diagnostics capability to pkg/seaice
1329      (will certainly be subject to changes)
1330    o ctrl: adding new control variables:
1331      lwflux, lwdown, evap, snowprecip, apressure, runoff
1332    
1333    checkpoint58q_post
1334    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1335      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1336      high_res_cube configuration by 4% on Columbia.
1337    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1338      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1339      dynamical allocation (seems to work in multi-threaded).
1340    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1341      single CPU io) so that TAF does not have to see EESUPPORT.h
1342    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1343    
1344    checkpoint58p_post
1345    o obcs: stop if obcs is used with useCDscheme = .true.
1346    o shelfice:
1347     - fix a sign error so that no slip at shelfice interface works
1348     - remove stop for combination non-hydrostatic code and shelfice. That does
1349       not mean, that the results are correct, but at least they are numerically
1350       stable
1351    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1352    o added adjoint exch routined for all exch*3d* routines
1353      and updated flow directives
1354    
1355    checkpoint58o_post
1356    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1357      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1358    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1359      and clean-up reading/writing of pickup files.
1360    o fix local version of read/write pickup (NH part) in rotating_tank/code
1361    o simplify EXCH interface:
1362     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1363     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1364    o added the regrid package
1365    o shelfice:
1366     - add a simple boundary layer scheme to reduce noise
1367     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1368    
1369    checkpoint58n_post
1370    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1371       local variable (not in common block).
1372    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1373      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1374      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1375        to work with SingleCpuIO.
1376    o add "_d 0" to real constant of pkg/cfc subroutines ;
1377       update exp. cfc_exemple & tutorial_cfc_offline output files.
1378    o multi-threading and IO:
1379      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1380        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1381      - barrier before and after reading.
1382      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1383      - avoid using MDS_WRITELOCAL for LAND pkg output.
1384      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1385        common-block variables ; Allows multi-threading with master-thread IO.
1386    o change default MAX_NO_THREADS from 32 to 4 ;
1387      and stop cleanly when MAX_NO_THREADS is too small.
1388    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1389    
1390    checkpoint58m_post
1391    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1392       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1393    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1394       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1395       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1396    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1397        add MITgcm_tutorials (= code + all the tutorials)
1398    o ecco, option to compute cost for total ssh (mean+anom)
1399    o consistent with addition of ptracer and ssh in pkg/profiles
1400    o profiles: adding ptracer and ssh
1401    o testreport: change multi-test output-file name
1402      (from output.txt.{name} to output.{name}.txt)
1403    o profiles: now ok for mutli-tiles case
1404    o seaice: add 4 parameters for different advection schemes for area,
1405      (effective) seaice thickness, enthalphy, and snow height. Their default
1406      is the standard parameter SEAICEadvScheme
1407    o calc_gw:
1408     - add cosFacU in zonal viscous flux (harmonic.visc.).
1409     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1410       of tutorial_plume_on_slope.
1411    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1412    o calc_gw: true flux-form, account for horizontal grid spacing.
1413      update rotating_tank results, but not plume_on_slope (affected at
1414      truncation level, 11 digits).
1415    
1416    checkpoint58l_post
1417    o calc_gw:
1418     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1419     - remove side-drag for now (need to fix it); update plume_on_slope results.
1420     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1421    o commit code to make SST/SSS weights spatially variable
1422      (based on either variable in-situ or variable initial T/S weights)
1423    o pkg/ecco:
1424      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1425        now based on horizontally varying weights wthetaLev, wsaltLev
1426      * cost_averagesflags now returns year indices in addition to day, month
1427      * sflux balance is performed on annual basis
1428        (sflxumm, sfluxmm2, bal_sfluxmm)
1429      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1430        including separate counting and multipliers
1431    o pkg/rbcs
1432      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1433    
1434    checkpoint58k_post
1435    o testreport:
1436     - always build in dir. "build" (if not there, mkdir build instead of building
1437       & running in input)
1438     - run in dir run (if it exists), in build otherwise.
1439     - call prepare_run (if input/prepare_run exists)
1440     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1441    o pkg/exf modifications to interpolation and rotation routines for more
1442       reasonable treatment of North Pole singularity: for tracers North Pole
1443       value is set to northernmost zonal-mean value, for zonal velocity it is
1444       set to zero, and for meridional velocity it is set to northernmost value.
1445    o pkg/exf/exf_check_range.F
1446     - add tile index to diagnostics and move stop statement to the very
1447       end of the routine.
1448    o pkg/diagnostics: (diagnostics_main_init.F)
1449      define title of isomorphic variables according to the current config.
1450    o pkg/thsice with pkg/seaice dynamics:
1451    - fix domain of computation (interior only, required for exf) and do exchanges
1452    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1453    o towards a standard way of dealing with multi-threading in MONITOR
1454      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1455    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1456       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1457    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1458    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1459    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1460       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1461    o tracer advection:
1462     - clean-up and simplify calc_common_factors.F
1463     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1464       advection subroutine (but still not used within DST advection S/R)
1465    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1466    
1467    checkpoint58j_post
1468    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1469      from file (collects calls previously in FORWARD_STEP)
1470    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1471    o adjoint store dir. adjusted accordingly
1472    o genmake2
1473      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1474    
1475    checkpoint58i_post
1476    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1477      on wind stress (SEAICEstressFactor defaults to 1.)
1478    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1479      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1480    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1481      on CS-grid: no longer loosing mass.
1482    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1483    o pkg/ggl90: fix sloppy output and fix a bug
1484    o pkg/seaice: added SEAICEuseEVPpickup parameter
1485      - Set to false in order to start EVP solver with
1486        non-EVP pickup files when using SEAICEuseEVP
1487      - fix sign error in diffusion in seaice_calc_rhs
1488    
1489    checkpoint58h_post
1490    * Modifications for bottom topography control
1491      o replace hFacC by _hFacC at various places
1492      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1493      o add non-self-adjoint cg2d_nsa
1494      o update autodiff support routines
1495      o re-initialise hfac after ctrl_depth_ini
1496      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1497    * Adding verification for 5x5 box (4-layer) bottom topography control
1498    
1499    checkpoint58g_post
1500    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1501       used for mean seasonal cycle, mean diurnal cycle); add an example
1502       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1503    o pkg/ggl90:
1504      - add parameter (minimum surface kinetic energy)
1505      - fix bug (avoiding division by zero)
1506    o couple pkg/thsice to pkg/seaice:
1507      - modify advection in seaice to accomodate new scalar fields to be advected
1508      - only muliDimAdection scheme work with seaice/thsice
1509      - mapping of thsice-variables to seaice-variables, back and forth
1510      - does not break the verification experiments, but does not give the
1511        desired results either
1512    o pkg/seaice
1513      - make (default) second order advection a bit less confusing?
1514    
1515    checkpoint58f_post
1516    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1517      to pkg/seaice):
1518      - new routines thsice_map_exf and thsice_get_exf provide the interface
1519      - add an additional formal parameter to thsice_solve4temp
1520    o pkg/exf:
1521      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1522      - correct Stefan-Boltzmann constant
1523      - new parameter for longwave surface emittance
1524      - separate some stuff from exf_bulkformulae into new routines  
1525        exf_radiation, exf_wind
1526      - add new parameters and constants: longwave emissivity for ocean, ice
1527        and snow, evaporation parameters over ice
1528      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1529        either wind from stress or stress from wind
1530    o pkg/thSIce:
1531    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1532    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1533       and THSICE_CALC_THICKN
1534    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1535    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1536      to make debugging easier.
1537    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1538    o pkg/bulk_force:
1539      - clean-up comments and parameters ;
1540      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1541    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1542      generate new output for test-experiment: aim.5l_cs.thSI
1543    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1544      testreport accordingly
1545    
1546    checkpoint58e_post
1547    o SEAICE_CGRID adjoint done
1548    o R_STAR adjoint implemented.
1549      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1550      * need to sort out init. of h0facc, etc.
1551    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1552      to be able to use it in pure forward.
1553    
1554    checkpoint58d_post
1555    o upgrade simple test-experiment to tutorial example:
1556     step.1: duplicate the experiment and (step.2) will remove the old copy.
1557      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1558      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1559      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1560      tutorial_global_oce_biogeo    <- copy of dic_example
1561      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1562      tutorial_plume_on_slope       <- copy of plume_on_slope
1563      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1564      tutorial_global_oce_optim     <- empty for now (David ?)
1565      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1566     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1567    o correct a sign problem in cost_scat.F
1568    o obcs and ptracers: fix boundary conditions for advections schemes
1569      with larger stencil
1570    o thsice adjoint: start
1571    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1572      completeness
1573    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1574      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1575    o ptracers adjoint:
1576      * avoid extensive recomputatations
1577      * fix missing re-init. of gptr (missed by TAF)
1578    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1579      me to turn off the excessive output to STDOUT that this package produces
1580    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1581      and add those terms in Vector-Invariant formulation.
1582    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1583      if the control period (xx_hfluxperiod etc) is 0
1584    o in profiles pkg, clean routines and fix details
1585    o in ecco pkg, reading ssh data:
1586      fix problem in case the model does not start at iter0=0
1587    o fix mnc-pickup/restart for ptracers
1588    o new package prifiles:
1589      code to compute profile-based cost by Gael Forget
1590      (modifs in ecco, ctrl, autodiff)
1591    o Benign bug fix in initialization (spotted by M. Mazloff) of
1592      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1593    
1594    checkpoint58c_post
1595    o adjoint: finish NLFS adjoint and provide reference output in
1596      verification/global_ocean.90x40x15/results_ad_nlfs
1597    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1598      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1599      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1600      with SEAICE_CGRID defined.
1601    o move calendarDumps from "data" to "data.cal" and clean-up the code
1602      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1603    o add useEXF & useCAL flags (for now, set in hard-coded way)
1604    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1605      (were missing in NH mode, and wrong in quasihydrostatic mode).
1606      waiting for Chris updated version of calc_gw to add those CALLs.
1607    o fix bug in quasihydrostatic S/R ;
1608      add a test for this option: global_ocean.90x40x15.qshyd
1609    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1610      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1611    o add on/off flag useOffLine for package OFFLINE
1612    o seaice:
1613      - modify advection so that it works also on the C-grid
1614      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1615        problem in multi-tile runs with C-grid
1616      - add flags for clipping ice velocities and/or masking solver forcing
1617      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1618        C-grid solver
1619      - added a few comments to seaice_diffusion.F
1620      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1621        are now exclusive)
1622      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1623        required re-ordering the code a little:
1624       + make DAIRN global variable (defined in SEAICE)
1625       + move computation of the viscosities eta and zeta into a new separate
1626         routine (because I need to recompute them in seaice_ocean_stress.F)
1627    
1628    checkpoint58b_post
1629    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1630      update output.txt of exp. aim.5l_cs.thSI
1631    o various mnc cleanups and improvements:
1632      + shrink lookup tables by factor of ~4
1633      + better error reporting when running out of lookup space
1634      + able to handle longer path/file names (up to 500 chars)
1635    o adjoint:
1636      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1637      - TBD: "hidden" mom_vecinv recomp. in dynamics
1638    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1639     (allow to differentiate between forcing components using new integer flags:
1640      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1641     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1642    o ecco
1643      - enable trend removal from SSH anomaly obs.
1644    o adjoint
1645      - a fix for PmEpR when #undef EXACT_CONSERV
1646      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1647      - try to fix "hidden" recomp. in forward_step for NLFS
1648        (NLFS seems broken sometimes after I checked it in)
1649    o seaice:
1650     - add c-grid version of the dynamic solver:
1651       + three new routines that are the c-grid substitute lsr, dynsolver
1652         and ostres
1653       + put a few fields that were local to dynsolver into global common
1654         blocks, so that I can move the computation of stresses etc into
1655         seaice_lsr (saves coding but may break the adjoint).
1656     - replace more hardwired parameters by runtime parameters
1657     - add ice masks that mask the rhs of the implicit solvers where there
1658       is no ice (commented out in seaice_dynsolver, because i am not sure
1659       if this works properly), eventually this should replace the clipping
1660       of ice velocities in seaice_dynsolver to +/-40cm/s.
1661    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1662      include it only where its needed
1663    o move balancing of fluxes before the call of external_forcing_surf
1664    o seaice:
1665      - correct units of turning angles (now they are really in degrees)
1666      - move computation of GWATX/Y out of main routine into dynsolver
1667      - initialize GWATX/Y in seaice_init
1668    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1669      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1670    o seaice: add runtime flags for turning angles (default to zero)
1671    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1672      and trend from exf forcing and ctrl control adjustments
1673    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1674      (since checkpoint57x_post)
1675    o change the default rotation period to 86164.s = the Earth rotation
1676    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1677      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1678    o seaice advection: add code for choosing between the default (2nd order
1679      central differences) and multiDim advection schemes provided by
1680      pkg/generic_advdiff
1681    o seaice:
1682      - removed all references to SEAICE_GRID.h fields from
1683        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1684        (cubed-sphere configuration will change a little)
1685      - grid computations in seaice_init are obsolete now.
1686      - cleaned up code a little so that is easier to read (hopefully).
1687      - added new (better?) discretizations of default advection and diffusion
1688        (turn on with SEAICEuseFluxForm)
1689      - replace 1 in 3d global fields by kSurface in growth.F
1690      
1691    checkpoint58a_post
1692    o seaice:
1693      - bug fix in advect.F
1694    o shelfice:
1695      - separate shelfice load anomaly from pload (breaks with time
1696        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1697        Its default is 0., but it may be computed more cleverly from (unknown)
1698        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1699        done offline. A good approximation of the pressure load anomaly is
1700        necessary to avoid large initial adjustment processes underneath
1701        deep-reaching shelfice.
1702      - small fix in ISOMIP shelfice_thermodynamics
1703      - add more sophisticated thermodynamics of Hellmer (1989), this is
1704        now the default
1705      - give a few constants more intuitive names
1706    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1707      if bulk formulae are used in long integration (especially EmPmR). Turn
1708      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1709      if balancePrintMean, the imbalance that is substracted is printed to
1710      STDOUT.
1711    o fix bug (typo) in obcs_apply_eta.F
1712    o add a new package shelfice which enables us to model the circulation
1713      underneath shelf-ice with draughts of hundreds of meters.
1714     - works
1715     - to do: + include improved thermodynamics
1716              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1717                instead of new field kTopC
1718              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1719                instead of new field R_shelfIce and new code in ini_depth.F
1720                and ini_mask_etc.F?
1721              + adjust vertical mixing schemes?
1722    o seaice pkg:
1723     - add a cpp-flag to include a simple formula for a salinity dependent
1724       freezing point of sea water at the surface
1725     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1726       meridional stresses are now different (and hopefully correct)
1727    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1728       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1729       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1730    o pkg/diagnostics: add options and parameters for regional-statistics
1731       diagnostics ; define regions by reading a region-mask from a file
1732       (might add other options later)
1733    o pkg/bulk_force:
1734     - add option and parameters to use AIM surface-flux formulae.
1735     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1736       others forcing fields (defined in PARM05, parameter file "data") are loaded
1737       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1738     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1739     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1740     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1741       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1742     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1743    
1744    checkpoint58
1745    o add "--embed-source" option to genmake2 which, when the supporting
1746      tools can be compiled (as determined by genmake2) will turn on the
1747      embed_files package which then embeds the entire MITgcm source code
1748      (*.[fFhc] + Makefile) used for the build within the executable
1749      - requested by CNH but off by default
1750      - adds a paltry <9MB to the mitgcmuv executable in most cases
1751      - only writes the output when useEMBEDSRC in eedata is true
1752    o clean up 3-dim. relaxation codes:
1753      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1754      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1755      * Thanks to Tom Haine for testing!
1756    
1757    checkpoint57z_post
1758    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1759      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1760    o fix the pickup behavior for obcs in combination with ptracers
1761    o fix a bug in ptracers_external_fields_load
1762    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1763      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1764    o transfered surface NH pressure to eta field (if exactConserv).
1765    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1766         and update lab_sea output.txt file.
1767    o completing 3-dim. relaxation code: additional term
1768         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1769      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1770      * At compile time, in "EXF_OPTIONS.h" set
1771          #define  ALLOW_CLIMTEMP_RELAXATION
1772          #define  ALLOW_CLIMSALT_RELAXATION
1773      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1774          tauThetaClimRelax3Dim = 15552000.0,
1775          tauSaltClimRelax3Dim  = 15552000.0,
1776      * 3 cases:
1777          1) Use a constant-in-time 3-dim. field
1778          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1779          3) Real-time relax. to time-evolving prescribed field
1780    o Adding Laplacian-type smoothness constraint on
1781      initial and boundary (forcing) controls (ic, bc)
1782      * enable at compile-time via
1783        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1784      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1785      * Absolute scale somewhat unclear so far
1786      * no area weighting was included since no other cost term does so far
1787    
1788    checkpoint57y_post
1789    First step for a NLFS adjoint
1790    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1791    o new init. routines for calc_r_star, calc_surf_dr
1792    o still need to deal with ini_masks_etc
1793    o testreport seemed happy
1794    checkpoint57y_pre
1795    
1796    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1797    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1798    o add new offset feature to offline pkg (plus minor cleanup)
1799    o cfc fixes for final year of integration
1800    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1801      be in GCHEM_OPTIONS).
1802    
1803    checkpoint57x_post
1804    o fix testreport Pb in multiple test experiment.
1805    o cleanup our namelist syntax in verification:
1806      - make it more F95 standards compliant (some work still needed)
1807      - allows the vast majority of our tests to work with gfortran
1808    o Non-Hydrostatic:
1809     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1810     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1811    o Allow to apply AB on T,S rather than on AB(gT,gS):
1812     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1813     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1814       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1815     - need a "clever" read_pickup to restart from the other AB formulation
1816    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1817    o remove some unused variables (reduces number of compiler warnings)
1818    o adjoint
1819      * Disable useVariableViscosity for adjoint for time being
1820        (there are a number of extensive recomputations)
1821      * Initialize certain variables needed for adjoint
1822    
1823    checkpoint57w_post
1824    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1825                 fix the singleCpuIO RS version of MDSWRITEFIELD
1826       and add a WARNING if using globalFiles=T with multi-processors.
1827    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1828      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1829    o tracer advection scheme:
1830      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1831       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1832       was not very convenient).
1833      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1834       (further tests needed for the implicit DST & Flux-Limiter schemes).
1835    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1836      and sRef for convenience, handy, when you want to initialize
1837      ptracers in a large domain with a constant non-zero value. Also,
1838      untangle ptracers_init.F a little.
1839    
1840    checkpoint57v_post
1841    o change dome exp. to use variable viscosity in side-drag terms.
1842    o remove all the files from the cfc_offline test since they are now
1843      incorporated into tutorial_cfc_offline which has been producing
1844      identical results for a few days of testing
1845    o add new parameter: sideDragFactor to enable half-slip-side BC
1846      and change side-drag S/R to use viscosity from mom_calc_visc
1847      (can switch back by setting sideDragFactor=0.); affects results at
1848      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1849       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1850    o vorticity & strain are now computed without masking, to account for
1851      no-slip-side BC in variable viscosity calculation ; mask is applied
1852      anyway later on, before computing advection/coriolis terms.
1853    o modify exp4 to test new obcs support for reading from external files
1854      and for passive tracers
1855    o fix behavior of ptracers_monitor when monitor output is written to a
1856      netcdf-file; still not independent of monitor.F (writes in the same
1857      file).
1858    o change default value of tRef (put a uniform, meaningful value for ocean
1859      & atmos) and initialize sRef (was missing, as Martin mentioned).
1860    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1861      to be proportional to enstrophy dissipation length.  Thus,
1862       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1863      This is now consistent with Smagorinsky and with the manual.
1864    
1865    checkpoint57u_post
1866    o OBCS and PTRACERS: add open boundary support for passive tracers
1867      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1868        OB-values from file; this is not different from the way theta and salinity
1869        are treated
1870      - however, Orlanski-radiation conditions are not supported, and the model
1871        will stop if you use pTracers and Orlanski at the same time.
1872      - beefed up the rountine obcs_external_fields_load: now only those open
1873        boundary values are overwritten with values from files for which there
1874        are really files, otherwise the OB-fields remain untouched. This makes
1875        it possible to use different OBs at different ends of the domain (as
1876        with EXF)
1877    o reduce number of exch calls in shap_filt (s2).
1878    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1879      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1880    
1881    checkpoint57t_post
1882    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1883    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1884      same truncation, independent of the face number: affects affects several
1885      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1886    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1887      note that biharmonic viscosity + no-slip was not tested in any experiment.
1888    o fix bug in non-linear free-surf side-drag ; generate new output for
1889      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1890    o make mnc honor the writeBinaryPrec flag for most kinds of output
1891    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1892    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1893      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1894    o add brackets in multi-terms sum to get same truncation, independent of
1895      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1896      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1897    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1898      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1899      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1900      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1901      Suggested values of viscosity parameters found in mom_calc_visc.
1902      Many new viscosity diagnostics available.
1903    
1904    checkpoint57s_post
1905    o Add clearing-house for viscosity calculations, mom_calc_visc and
1906      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1907      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1908      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1909      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1910      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1911      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1912      ViscAhStrain and viscAhTension are now retired.
1913    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1914    o In response to JMC's bug report, genmake2 now ignores any soft-links
1915      that it finds in the *current* directory when searching for files.
1916      Soft-links found in any other source directories will still work as
1917      they did before.
1918    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1919      a C routine to unlimit the stack size
1920    o mnc-ify pkg/aim snapshot vars
1921    o mnc-ify pkg/land as requested by Daniel
1922    o various changes to mnc including:
1923      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1924      - output can now be grouped so that all files within a group
1925          change the ITER portion of their names in lock-step together
1926      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1927          and works with both EXCH1 and EXCH2 (but needs more testing)
1928      - writing works for all verification test cases w/ g77 on Linux
1929    
1930    checkpoint57r_post
1931    o make MNC variable initialization happen earlier
1932    o add diagnostics for (almost) each term of the momentum Eq.
1933    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1934    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1935    o remove MINIMAL_TAVE_OUTPUT option ;
1936      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1937    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1938      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1939    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1940    o add time-dependent SST, SSS control
1941    o cost terms in ecco/ modularized (new cost_generic.F)
1942    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1943    o new infrastructure for seaice model vs. obs misfits in seaice/
1944      * driver from the_main_loop.F is seaice_cost_driver.F
1945      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1946      * gradient check in Exp. 6a of natl_box_adjoint/
1947    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1948      (see README file)
1949    
1950    checkpoint57q_post
1951    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1952    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1953      - bug was reported by Jean-Michel and Ian Fenty
1954    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1955      update exp. cpl_aim+ocn output.
1956    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1957      Needed for high-res. runs with large global files
1958      to be able to limit tapelev size
1959    o Changed some tests for adjoint:
1960      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1961      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1962      * global_ocean.90x40x15/ back to default 3-level checkpointing
1963    o Modifications to enable scripted COMMON to MODULE conversion
1964      * verification/OpenAD/code/ has necessary scripts and description;
1965      * converts, compiles and runs successfully;
1966    
1967    checkpoint57p_post
1968    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1969    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1970      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1971    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1972    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1973      (was already the case for dissipation with mom_vecinv,
1974       and also the case for grad.PhiHyd when staggered-timeStep)
1975      This will allow to put dissipation out-off the AB time-stepping.
1976     Unfortunately, affects truncation error. Update output of exp. that "fails"
1977      (cg2d matching number) and leave the others for later: front_relax(10),
1978      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1979      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1980    
1981    checkpoint57o_post
1982    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1983      (2) its ready to be documented during the 20050801 DocFest
1984    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1985      for ideal_2D_oce and lab_sea on linux_ia32_g77
1986    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1987      in global1x1_tot/code_seaice_adj to access indices 32, 33
1988      (worth another tag)
1989    
1990    checkpoint57n_post
1991    o adding precip control xx_precip 32
1992    o adding swflux control xx_swflux 33
1993    o Replacing 10 forcing penalty cost routines by 1 generic.
1994    o Implementing partitioning in time-mean and variable adjustment
1995      for atmos. state.
1996    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1997  o in natl_box_adjoint:  o in natl_box_adjoint:
1998    * updated: results_bulk/    * updated exp 1 to 10
1999    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
2000    o updated global1x1/*_seaice_adj/
2001      to incorporate latest changes
2002    o enable useSingleCpuIO for mdsio vector routines
2003      (applies in particular to tapelev I/O)
2004    o removed inefficient K-loop in all active_file*control*.F
2005    
2006  checkpoint57m_post  checkpoint57m_post
