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