4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
8  o moved ptracer ctrl index 17 -> 32    of salt_plume package in Southern Ocean
9    o pkg/thsice:
10     - fix hOceMxL in overlap (needed for sea-ice advection);
11       update output of experiment global_ocean.cs32x15.icedyn.
12    o pkg/seaice:
13     - make the (placeholder-)tracer IceAge a little more meaningful
14      by avoiding ridging of age due to convergent ice flow
15     - add diagnostics for surface temperature
16    
17    checkpoint61p
18    o eesupp (global_max & global_sum):
19     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
20     - remove starting & endding barrier (no longer needed)
21    o pkg/mdsio, writelocal:
22       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
23       (remove the STOP): uses shared buffer IO to store data from all threads
24       and then let master-thread write nThreads tiles.
25    o pkg/mdsio (read/write field):
26     - tiled IO done in 1 piece (all levels at a time);
27     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
28     - multi-threaded: allow to read/write local (non-shared) array
29       (was already working with singleCpuIO ; now works also without);
30       => no longer needs barrier call after reading a file (added inside
31       mds_read/write field).
32     - move barrier calls outside gather/scatter_2d to mds_read/write_field
33    o pkg/obcs/exf
34      - exf_getffieldrec.F: add a few ". _d 0" and
35                            add code to catch the case fldperiod = 0.  
36      - obcs_precribe_read.F: change if statements so that they match
37                              the variable type (_RL)
38      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
39        exf_iprec) as part of namelist EXF_NML_01
40    o pkg/mdsio:
41      - read/write tiled (local) files: read/write 1-level tile chunk at a time
42        (instead of segment of length sNx); expected to speed up tiled IO.
43    o pkg/exch2:
44      - take buffer copy from/to array out of S/R exch2_send/recv into new
45        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
46        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
47      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
48      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
49        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
50        including Topology header file (and common blocks).
51      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
52        remove 2nd exch call in exch2_s3d_rx (no longer needed).
53      - document S/R arg. list (+ update some comments)
54    o pkg/seaice:
55      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
56        temperature and humidity over sea ice based on climatological values.
57      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
58        of LSR (this change is expected to change the results slightly because now
59        it uses slightly difference moduli from the second last LSR solution, but
60        that is more consistent with the stress computations; this part of the code
61        is not tested in the verification experiments)
62      - fix diagnostics for flux of ice in case of B-grid
63      - turn strain rates eij and press into global fields within global
64        common block in SEAICE.h for more straighforward diagnostics
65      - fix diagnostics for principal stress components, press, zeta, eta
66        to give something meaning full
67    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
68      new output (all 4 tests) using default rotationPeriod.
69    o pkg KPP:
70      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
71      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
72        and normal grid from 1 to Nr)
73    o Fix computations of L4rdt in mom_calc_visc.F
74    o eesupp:
75      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
76      should be called before a "stop" if we know that all process are going
77      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
78    
79    checkpoint61o
80    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
81    o model/src/ini_curvilinear_grid.F:
82       compute angleSin/CosC when they are not read from a file
83    o pkg/seaice:
84       add pseudo time stepping for LSOR
85    o pkg/exch2:
86       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
87    o pkg/seaice:
88       Adding separate sea ice albedo, drag coefficients, and HO in Southern
89       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
90    o SingleCpuIO:
91       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
92    o pkg/seaice:
93       put exchanged variable in (local) common block for MPI+Multi-Threads
94       to work (necessary with exch1, and for now with exch2 too).
95    o verification: to get more experiments tested with mpi, mth and mpi+mth,
96      change tiling of:
97       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
98       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
99      update output of exp:
100       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
101       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
102      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
103                       (note: output.txt generated on faulks using only 1 tile)
104    o eesupp & mdsio (SingleCpuIO):
105     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
106       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
107       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
108     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
109     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
110       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
111    o pkg/exch2:
112     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
113       read parameter file "data.exch2" if it exists; otherwise try default regular
114       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
115     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
116       with new code (not to be used, just as a backup solution).
117     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
118       in utils/exch2/input.
119    
120    checkpoint61n
121    o eesupp & mdsio (SingleCpuIO):
122      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
123        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
124        receive real*4 array (instead of real*8) to read/write 32.bit files.
125        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
126         and remove new mapping S/R)
127    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
128      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
129        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
130        when using exch2. Add S/R to map global io-buffer to global model array.
131      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
132    
133    checkpoint61m
134    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
135      and add 3 other S/R for other types (R4,R8,RS).
136      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
137    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
138     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
139     - reduce number of macro definitions (keep only those which are used);
140       can always call directly the corrresponding S/R if needed.
141     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
142       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
143     Fixed wrong type of arg in:
144       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
145       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
146     To fix: global_sum of var in common block is wrong (multi-threaded) in:
147       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
148     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
149    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
150      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
151    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
152    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
153      edges are closed (zero depth); might happen with "blank tiles";
154      for now, disabled if using OBCS.
155    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
156      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
157    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
158      to reduce length of 1.D array print in STDOUT.
159    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
160      + use 48 tiles (16x8): this will allow to test "blank tiles".
161    o start to test MPI + multi-threaded (change testreport to skip tests
162      where number of tiles do not match).
163    o genmake2: add option "-omp" to turn on Open-MP ;
164      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
165    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
166      and keep the original tile numbering. Note: compatible with old
167      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
168    
169    checkpoint61l
170    o Overlaps had been forgotten in calculating ijk keys : fixed
171    o fix cyrus makedepend for gcc 4.4
172    o experiment fizhi-cs-aqualev20:
173      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
174      and generate new output. Note: new output is much closer to the old
175      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
176      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
177    o pkg/fizhi:
178     - change to avoid indices going deliberately over array-bounds
179     - remove unnecessary MPI stuff
180     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
181     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
182       does not go over array-bounds and therefore returns reliable output.
183     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
184       this S/R has 4 output arguments, which are used inside "get_alarm";
185       when it is called with the same variable "ndum" in place of several
186       output arguments, this produces weird side effect inside "get_alarm"
187      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
188       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
189       address) and produces error.
190    o tools/gemake2: (March 27-29 2009)
191      with option "-mpi": link *_mpi files from "MODS" dir (this is what
192      testreport does).
193    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
194    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
195       update lab_sea.lsr & lab_sea.salt_plume results
196    o pkg/seaice:
197      Major overhaul of the LSOR solver: change discretization from original
198      finite differences to finite volume. The old routine is still in the
199      file seaice_lsr.F and can be turned on with the CPP-flag
200      SEAICE_OLD_AND_BAD_DISCRETIZATION
201      Along with this change, the discretization of the strain rates is changed.
202      The same flag turns on the old discretization in seaice_calc_strainrates.F
203      All verification experiments with seaice are affected (except for
204      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
205      results by setting the above flag.
206      Further changes involve changes in defaults:
207      - ALLOW_FLOODING is defined and turned on by default
208      - SEAICEadvSnow = .true. is now the default
209      - SEAICEadvSalt = .true. is now the default
210      - SEAICEadvAge  = .true. is now the default
211      - SEAICE_clipVelocities  = .false. is now the default
212                                         (as per J. Zhang's recommendation)
213      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
214        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
215      - seaice_growth: replace computation of UG by a simple copy from wspeed
216    
217    checkpoint61k
218    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
219      seaice_lsr: fixed a few metric terms,
220                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
221                  add more debugging diagnostics
222      seaice_evp: removed superfluous many metric terms of FV discretization
223                  of stress divergence
224                  affects lab_sea, lab_sea.hb87
225      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
226                  of stress divergence for non-evp solver
227                  (this part is not tested anywhere)
228      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
229                  they were effectively only half slip
230                  affects lab_sea.hb87
231      updated all relevant verification experiments (except lab_sea//output_adm.txt
232        which was left over, but fails at level 7 & 6)
233    
234    checkpoint61j
235    o pkg/seaice: turn a few hard wired parameters into run time parameters
236    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
237      time in seconds as promised by the usints in seaice_monitor and exf_monitor
238    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
239      that are not cubed-sphere grids
240    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
241    o pkg/ctrl:
242      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
243    o non-hydrostatic (calc_gw.F):
244      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
245      update output of exp. global_ocean.cs32x15.viscA4
246    o remove backward compatibility for thetaMin,phiMin
247      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
248    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
249      interpolated wind field not only for curvilineargrid=.true., but also
250      for a rotated grid (rotateGrid=.true.)
251    o pkg/exf: add capability to bypass interpolation for runoff
252      by setting yet another CPP-flag
253    o eesupp/src, B-grid exchange:
254      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
255    o autodiff
256      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
257      allows to switch to single-prec common blocks;
258      corresponding switch occurs in tamc.h, integer isbyte
259      TAF store directivs "byte" and "kind" seem equivalent;
260      Most tamc.h have been updated correspondingly.
261    
262    checkpoint61i
263    o autodiff:
264      fix autodiff_sore/_restore indices for obcs
265      (spotted by I. Hoteit, M. Mazloff)
266    o pkg/autodiff, pkg/ctrl:
267      Add flag to reduce all tapelev I/O to single-prec.
268      In data.ctrl set
269        doSinglePrecTapelev = .TRUE.
270    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
271      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
272    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
273      real fresh water flux (not yet)
274    o pkg/mdsio & rw:
275     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
276     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
277    o pkg/flt:
278     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
279       init_fixed & ini_varia.
280     - clean-up & simplify linear interpolation S/R:
281       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
282     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
283     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
284     - add vert. coordinate & horiz. indices to output files.
285     - change vertical position in initial condition, from index to depth [m].
286     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
287       (easier to get to a curvilinear grid) ; delX,delY no longer used.
288    o pkg/ggl90: a few modifications:
289     - fix bottom boundary condition, and interpolation of KappaE
290       near top and bottom
291     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
292     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
293     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
294    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
295      (maintain temporary backward compatibility, until next checkpoint)
296    
297    checkpoint61h
298    o pkg/diagnostics with "periodic averaging diagnostics":
299      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
300    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
301    o pkg/obcs: fix loop ranges for balancing code
302    o pkg/flt:
303     - improve criteria for finding which tile owns a float.
304     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
305    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
306      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
307      with ocean biogeo)
308    o pkg/flt:
309     - do some cleaning and fix the restart ;
310     - add output.txt in flt_example/results to get this pkg tested.
311    o genmake2: add an EXTENDED_SRC option and flag.
312       for now, cannot be turned on on command line (only through genmake_local)
313    o pkg/mdsio: read/write vector:
314     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
315     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
316       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
317     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
318      (drop to 4 digits matching for grad). But this test does not look very
319      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
320    
321    checkpoint61g
322    o pkg/flt:
323      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
324       + make OPTIONS file more standard.
325      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
326      - fix _BYTESWAPIO CPP-Flag
327      - standard reading of file-parameter "data.flt"
328      - fix argument list of S/R FLT_RESTART
329      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
330    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
331    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
332      a still unfixed compiler/optimization bug
333    
334    checkpoint61f
335    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
336      update results of global_ocean.cs32x15.icedyn test.
337    o move getcon.F from model/src to pkg/fizhi.
338    o pkg/exf: add parameter for extrapolation of temp up to the surface
339       and option to prevent negative evap (in bulk_largeyeager04 only).
340    o Prather Advection scheme: fix tracer conservation for divergent flow
341      (e.g., when using NonLin Free-Surface).
342    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
343    o gmredi (Visbeck-variable-K):
344     - add more parameters to Visbeck-variable-K.
345     - use a 5 points average for dSigmaR in Visbeck-K calculation
346       (more "homogenous": same stencil and same weights as in dSigmaH)
347     - update output of ideal_2D_oce experiment.
348    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
349      (#undef REAL4_IS_SLOW)
350     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
351       coordinate variable
352     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
353       (surface forcing fields), removes some of the functionality
354     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
355     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
356       probably not all: copy _RS surface flux fields to RL field before
357       calling DIAGNOSTICS_FILL
358     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
359       real*4 (CALL EXCH_*_RS) versions.
360     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
361       (generate new output).
362    
363    checkpoint61e
364    o gmredi (Visbeck-variable-K):
365      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
366      - change computation of Visbeck-K where Slope > Smax :        
367        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
368        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
369    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
370      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
371    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
372    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
373      does not become too large (to avoid precision problems in implicit-diffusion
374      solver); update ideal_2D_oce output.
375    o pkg ggl90:
376      - in ggl90_cal.F: compute only one set of visc/diff, used to
377        step forward TKE/T/S/momentum
378      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
379        have Prandlt =1)
380    o gmredi (fm07):
381      - add lower limit on Transition layer thickness + lower limit on 1/lambda
382      - allow to set few more params from data.gmredi
383    o pkg ggl90:
384          - add missing sqrt(2) factor in computation of mixing length
385            scale in ggl90_calc.F
386            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
387    
388    checkpoint61d
389    o adjoint modifs
390      - adapt to new field rhoInSitu
391      - allow to revert from StoreDynVars2D, StoreDynVars3D
392        to individual fields
393        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
394    o store 3-D (in-situ) density in commom block (DYNVARS.h)
395     - save 1 rho computation.
396     - no longer modify T & S inland when using down_slope pkg.
397    o gad_som : allow to switch to SOM advection for T & S without corresponding
398      pickup files (using new S/R: MDS_CHECK4FILE).
399    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
400      (for useSingleCpuIO to work in multi-threaded)
401    o pkg/shelfice:
402     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
403       with SHELFICEtopoFile in data.shelfice
404     - move code for reading ice shelf topography and modifying hFacC into separate
405       subroutines of the shelfice package
406     - separate initialisation of "fixed" and "variable" variables
407     - kTopC is not (yet) replaced by kSurfC, although this is possible
408    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
409    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
410      and rename:
411      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
412      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
413    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
414    
415    checkpoint61c
416    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
417      to add mass source/sink of fluid in the interior (3-D generalisation
418      of oceanic real-fresh water flux).
419    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
420    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
421    o new pkg: down_slope
422      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
423      - presently, modify T & S inland (dwnslp_calc_rho.F).
424        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
425      - implementation for ocean in P-coords not tested.
426      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
427    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
428      (to facilitate conversion of oceanic pkg to p-coordinate).
429    o change FIND_RHO to FIND_RHO_2D :
430      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
431    o new pkg: cheapaml
432    
433    checkpoint61b
434    o exch2:
435      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
436      - no longer depend on the order sequence (N,S,E,W).
437      - 3rd exchange no longer needed (tested with 24 tiles).
438      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
439      - exch_UV_A-grid readily available (but not yet tested).
440      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
441      (both are no longer needed) in exch_uv: no effect in forward run; but
442       get truncation error differences with adjoint exch.
443    o exch2:
444     - change index-bounds storage (moved from target to local tile,
445       more intuitive this way) ; rename/remove some variables.
446     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
447    
448    checkpoint61a
449    o exch2/matlab-topology-generator:
450      fix bug in index bounds for N-S internal exchange (hard to tell if this
451      had any effect on the solution).
452    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
453      is exceeded
454    o testreport: modify syntax of awk, so that it works also with
455      awk, and not only with nawk and gawk
456    
457    checkpoint61
458    o autodiff
459      Change default for TAF usage by removing argument '-nonew_arg'
460      This changes TAF subroutine argument list (ordering of active var.)
461      Omission of this flag leads to incompatibility w.r.t. TAMC
462      To restore TAMC-compatibility, need following modifs:
463      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
464      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
465      Tested TAF version is 1.9.22
466      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
467    
468    checkpoint60
469    --->>> This is the last checkpoint for which generating the adjoint
470    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
471    --->>> by default.
472    --->>> Future checkpoints will ommit this flag by default.
473    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
474    o pkg/grdchk: Add gradient check to etan0 perturbations.
475    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
476    o pkg/autodiff: more flexibility in zeroadj.
477      model/src: modifying do_oceanic_phys.F accordingly.
478    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
479    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
480      special setup of gmredi for which the adjoint is stable
481      enough for parameter optimization.
482    o bridging the gap between eddy stress and GM.
483      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
484          along with a change in CPP option (now ALLOW_EDDYPSI).
485      -> when using GM w/ GM_AdvForm:
486          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
487          is applied either in the tracer Eq. or in momentum Eq.
488          depending on data.gmredi (intro. GM_InMomAsStress).
489      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
490      The key modifications are in model/src/taueddy_external_forcing.F
491      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
492    
493    checkpoint59r
494    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
495      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
496      fix option to read coriolis(@ cell-corner) from files with CS-grid.
497    o pkg/mnc: add some attributes to standard 1D-coordinate variables
498    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
499      mass points, when using mnc for output
500      - add runtime parameter (missing_value, missing_value_int) to override
501        default (which is the value of getcon('UNDEF'))
502    o pkg/mnc: prepare mnc for the actual use of missing values with the
503      diagnostics package: small fix in mnc_cw_readwrite.template and more
504      initialisation of never used fields
505      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
506      versions
507    o pkg/thsice/thsice_ini_vars.F added default initial values so that
508      thermodynamics sea ice solver does not blow up when some initial fields
509      are missing.
510    o move from external_forcing_surf.F to ini_forcing.F
511      the p-coord. hack consisting in using pLoad to set phi0surf ;
512      update output of tutorial_global_oce_in_p (affected @ truncation level).
513    o Freshen up a bit hs94.1x64x5, notably:
514      remove rotationPeriod and tRef=5*0. (adjoint only), and add
515      exactConserv=.TRUE.
516    o pkg/generic_advdiff:
517      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
518      applies to files where Temperature & Salinity 2nd Order moments are used.
519    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
520      this uses a dynamically allocated internal state data structure
521      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
522      and requires a fortran 90 compiler
523    
524    checkpoint59q
525    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
526       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
527    o Refresh tutorial_global_oce_biogeo, notably:
528      - change bathymetry (put back seamounts in ACC, use hFacs)
529      - change EOS (POLY3 --> JMD95Z)
530      - use Bryan-Lewis vertical diffusivity
531      - use multidimensional advection
532      - remove old virtual virtual in dic pkg, now done through ptracer pkg
533      - change a couple of parameters in dic pkg
534    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
535    o pkg/obcs: change default to OBCSfixTopo = .true.,
536      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
537      - replace "debugMode" with "debugLevel .GE. debLevB"
538    o implementation of TAF directives for gchem,cfc,dic
539    o remove "exp5" (replaced by tutorial_deep_convection).
540    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
541      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
542      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
543      --> changes results in exp4, seaice_obcs
544    o tutorial_deep_convection :
545      update the set-up and increase resolution and domain size ; start
546      from pseudo initial conditions = output at t=120mn in order to see
547      something happening when running testreport.
548    o pkg/seaice: add os7mp as an advection scheme
549                  add check for advection schemes
550                  add a flag for restoring T and S underneath sea ice
551    o pkg/my82: add netcdf-support and diagnostics
552    o thsice pkg:
553      - Now hsMax limits snow height by turning it into ice following
554        flooding scheme (and now conserving energy)
555      - Slight rewriting of the formula in thsice_calc_thick.F
556      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
557      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
558    
559    checkpoint59p
560    o gchem / dic / cfc :
561      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
562      - add new parameter files: "data.dic" & "data.cfc" ;
563      - various re-arrangement in initialisation & header file ;
564      - fix tutorial_global_oce_biogeo for multi-threaded test.
565    o pkg/dic: test for "pickup_dic" file when restarting ;
566      if no pickup-file, can restart with a re-initialised pH (same as it did
567      before) providing pickupStrictlyMatch is set to False.
568    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
569      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
570    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
571      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
572    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
573     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
574       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
575    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
576       scheme to use for vorticty-term ;
577     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
578       (with default selectVortScheme, return to original discretisation)
579     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
580    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
581    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
582      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
583      also fix diagnostics VISCAHW & VISCA4W.
584    
585    checkpoint59o
586    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
587    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
588      move a few statemens out the main loop into separate loops
589    o pkg/shelfice:
590      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
591        (kg/m^2/s), does not break tests, because in verification/isomip,
592        rhoConstFresh=rhoConst (by accident)
593      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
594      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
595        new file model/src/seawater.F, so that they are available for all pkgs.
596      - convert potential temperature into in-situ temperature. This changes the
597        isomip tests => update tests
598    o add a flag writePickupAtEnd (default=true) to be able to suppress
599      writing a pickup at the last timestep
600    o tools/mpack-1.6 :
601      - disable automake (not working) and autoconf (not needed).
602      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
603        also cleaner with much less compilation warnings.
604    o pkg/profiles:
605      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
606      (for "less than 32 characters name" compiler requirement)
607    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
608      conditions that have a different sampling frequency than S/T/U/V obcs
609    o pkg/diagnostics (stats-diags):
610      - fix global Min/Max in case 1 processor get only empty tiles
611    o genmake2: replace (4 times)
612         make genmake_tc_1.o >> genmake_warnings 2>&1
613      with
614         COMM="$CC $CFLAGS -c genmake_tc_1.c"
615         echo $COMM >> genmake_warnings
616         $COMM >> genmake_warnings 2>&1
617      to make genmake2 always see the value of CC as specified in the optfile.
618    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
619      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
620      - modify verification advect_cs test to test SOM-advection on CS-grid.
621    o pkg/ctrl:
622      - Rewrite of ctrl_map_ini_ecco.F,
623        introducing a generic routine (ctrl_map_ini_gen.F).
624      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
625    
626    checkpoint59n
627    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
628      number in dedicate array "hdiag":
629      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
630        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
631      - many small changes (integer format) for large number of diagnostics
632      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
633        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
634    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
635      usingSphericalGrid, this allows to define the rotated grid coordinates
636      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
637      geographical coordinates according to the inverse of the rotation defined
638      by the Euler angles, so that Coriolis parameter and online-interpolation by
639      exf works with the geographical coordinates on XC/YC/XG/YG.
640      Naturally, this feature does not work with all packages, so some
641      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
642      profiles), because there the coordinates are assumed to be regular
643      spherical grid coordinates.
644    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
645      - introduce isopycnal diffusion coefficient control.
646    o tools/adjoint_options:
647      - additional control vector components.
648    o pkg/mnc: have mnc create marginally meaning full coordinate variables
649      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
650    o pkg/mypackage:
651      - add example of read/write pickup for state-var ;
652      - add entry points to the main code for state-vars diags & write-pickup.
653    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
654      transitions for useExfYearlyFields
655      - add new subroutine that determines the file to read from for
656        use*YearlyFields = .TRUE. and .FALSE.
657      - add a verification experiment to global_with_exf that tests
658        useExfYearlyFields with USE_EXF_INTERPOLATION defined
659    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
660      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
661      subroutines (which could be generated from a template, because they are
662      almost identical), for now they are included in obcs_prescribe_read.F for
663      simplicity
664    o pkg/exf:
665      - add a little more diagnostic to exf_interp_read (in analogy to
666        mds_read_field, can be turned off with debugLevel < debugLevA=1)
667      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
668        ugly but fast by unrolling short inner loops, inserting a unroll=8
669        directive in routine lagran, and splitting a loop and making do while the
670        outermost loop (the latter requires the intoduction of index arrays)
671    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
672    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
673      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
674    o verification/seaice_obcs: updated for restart test and latest options
675    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
676      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
677      for now this is only available for the C-grid code and also within
678      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
679    
680    checkpoint59m
681    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
682      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
683    o gad_som : fix flux output (& diagnostics) to have same units as other  
684      advection scheme fluxes (was previously multiplied by deltaT).  
685    o added verification/seaice_obcs both to test seaice open boundaries
686      and to provide an example matlab scrpt for generating them
687    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
688    o pkg/salt_plume: clean up salt_plume_frac.F to
689      remove redundancy in PlumeMethod 1 and 4
690    o pkg/kpp: added saltplume diagnostics
691    o pkg/obcs and pkg/seaice:
692      - do not set uice and vice to zero when OB*icefile are unspecified
693      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
694      - moved seaice tracer obcs after call to seaice_growth
695    o pkg/salt_plume: added various options for salt plume depth
696      criterion and for vertical distribution of the salt
697    
698    checkpoint59l
699    o pkg/ptracers: new version of ptracers pickup:
700      read meta file and write only fields which are needed to restart.
701      ( same logic as main pickup file ; also using pickupStrictlyMatch )
702    o pkg/seaice:
703      - add timescale for melting due to warm mixed layer as a means of
704        setting SEAICE_availHeatFrac more conveniently
705      - add a CPP-flag/runtime parameter check for flooding algorithm
706      - reformulated availHeat in seaice_growth.F to be independent of AREA
707    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
708      unit changes
709    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
710    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
711      SX vector computer.
712    o pkg/seaice:
713      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
714        seaice forcing fields can now be read only through pkg/exf
715      - removed some unused halos
716    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
717    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
718      or U/VICE from U/VWIND before computing U/VSTRESS
719    
720    checkpoint59k
721    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
722      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
723    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
724      all experiments pass when compile with un-initialised var. checking option.
725    o added pkg/salt_plume
726    o script to test restart (for now, in MITgcm_contrib/jmc_script)
727    o pkg/seaice: new read/write pickup version.
728      read meta file and write only fields which are needed to restart.
729      ( same logic as main pickup file ; also using pickupStrictlyMatch )
730    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
731    o lab_sea.hb87: modify the domain & update output.hb87.txt :
732      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
733      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
734      process. Fixed here by closing the domain at the Northern boundary.
735    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
736    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
737      a set of consecutive levels in/from a 3-D array.
738    o pkg/ptracers:
739      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
740      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
741    
742    checkpoint59j
743    o in pkgs: dic, obcs, offline, rbcs:
744      standard way to compute coeff. for time interpolation between 2 time reccords
745      which retains full precision (& make results less dependent on compiler).
746      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
747    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
748      packages instead of reading ice cover and wind speed separately
749    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
750     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
751      to allow to compile customized code before the update)
752    o cleaning-up:
753      - fix CPP instruction syntax in pkg/obcs
754      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
755        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
756      - fix some threads issue in IO parts.
757    o pkg/dic:
758      - add tons of "_d 0" (--> much better testreports !)
759       and then update outputs of tutorial_global_oce_biogeo
760    o pkg/mom_fluxform:
761      add a special version of momentum advection intended to conserve momentum
762      next to a bathymetry step or a coastline edge. (default = off = #undef)
763    o new read/write pickup version:
764      - for now, only implemented for main (mdsio) pickup file.
765      - write out only what is needed to restart; merge pickup_nh , pickup_ph
766        and main pickup together.
767      - read meta file; read only what is needed to restart; stop if a field
768        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
769        if it make sense (even if the restart is not perfect).
770      - if no meta file, assume that pickup to read corresponds exactly to
771        a pickup that would currently be written.
772      - read pickup written in the old format (until checkpoint59i) if it
773        recognizes an old meta file (no field-list).
774      - add a meta file in exp. which starts from a pickup: 2 cases:
775        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
776         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
777        b) a meta file describing the content of the associated pickup file
778         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
779    o pkg/mdsio & pkg/rw:
780      - new routine to read a meta file ; new set of routine to read
781        Multiple-fields file (with meta file).
782    o added open boundary conditions capability for seaice
783        HSNOW, HSALT, UICE, and VICE
784    
785    checkpoint59i
786    o adjoint:
787      * fix multiDimAdvection adjoint
788        (partial recomputation problem by TAF for fVerT(:,:,kDown)
789        and comlev1 size definition (maxpass vs. max. number of tracers)
790      * verification/global_ocean.90x45x15 adjoint now tests
791        NLFS and multiDimAdvection using DST3 (=30)
792      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
793    o pkg/kpp: add "_d 0" to real constant (if missing);
794      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
795      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
796    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
797      for internal parameters related to restart process (formerly from PARAMS.h)
798      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
799    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
800      as argument. (only atm2d & obcs write_pickup have not yet been updated)
801    o pkg/monitor:
802      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
803      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
804      - account for deep Atmosphere factor and density factor (anelastic)
805    o added open boundary conditions capability for seaice HEFF and AREA
806    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
807      thermodynamics
808      - requires a little reorganization, which affects the testreport results
809        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
810        so that now the conservative form is tested
811      - add a few comments
812    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
813    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
814    o add new diagnostics to seaice: advective, diffusive fluxes (only for
815      multidim-advection, for scheme 2 they are not filled) and transports,
816      thermodynamic growth rates
817    o change units of EmPmR (inside the code, + within coupling interface)
818      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
819      Affects results @ truncation level (cg2d match) and update output of
820       experiments: lab_sea(6), global_ocean.90x40x15(10),
821      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
822      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
823      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
824      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
825    
826    checkpoint59h
827    o pkg/exf:
828      - improve vectorization by moving if-statement out of loops in
829        exf_mapfields, exf_radiation
830      - exf_bulkformulae.F: introduce 2D fields and vectorize code
831    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
832    o testreport:
833      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
834        monitor & update offline_exf_seaice exp. output.
835      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
836    o pkg/seaice:
837      - bug fix in the evp solver: boundary conditions were affected be
838        masking of zMax/zMin (changes results)
839      - minor bug fix in boundary conditions in seaice_calc_strainrates
840        (changes results for no_slip)
841      - seaice_lsr.F: make interpolation of eta dependent on boundaries
842      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
843      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
844        stress formulation and no-slip boundary conditions
845    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
846      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
847    o pkg/seaice: a first HSALT time stepping equation has been checked in
848    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
849      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
850      without requiring DO-IF statements
851    o pkg/thsice:
852      use continuous power-law function for partition of energy between lateral
853      melting/freezing and thinning/thickening ; old code using step function
854      still available with #undef THSICE_FRACEN_POWERLAW
855      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
856    o testreport: change AD testing : check against results/output_adm.txt
857      using same scripts as for forward test.
858    
859    checkpoint59g
860    o adjoint testing: in preparation for changing testreport:
861      - output format: cost and grad written on separated lines
862      - ad output results in directory "results" (instead of "results_ad")
863    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
864    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
865    o pkg/ecco: allow user defined cost function contributions
866    o testreport:
867      Allow to choose (per experiment) the list of tested output variables
868       and the main variable (used to issue a pass/FAIL ) ;
869      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
870      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
871      Also modify printing of summary:
872       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
873       b) echo the list of tested variables in the individual summary.txt of
874          each experiment.
875    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
876      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
877      (but still depend on the tile decompostion of the domain).
878    o pkg/seaice: change a discretization detail to make the B-grid code
879      "more symmetric". This change is likely to remove all "ridges/leads" that
880      where quasi-aligned with the grid in B-grid solutions. It may also be
881      the solution to the stress coupling issues with the B-grid.
882    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
883      remove .cvsignore from input dir. (since testreport no longer run here).
884    o pkg/thsice:
885     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
886     - fix reshaping of sea-ice just after advection:
887       melt all the ice only if ice-volume is too small.
888     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
889       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
890     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
891    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
892      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
893    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
894      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
895      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
896      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
897      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
898      -> update output.txt
899    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
900     this affects truncation error: -> update output.txt of exp:
901      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
902      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
903    
904    checkpoint59f
905    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
906    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
907      a bounded range (in forward mode)
908    o pkg/ecco, ctrl, autodiff and mom_common:
909     internal parameter controls, completements of implementations
910    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
911    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
912      (not seem any difference in testing results).
913    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
914       at face corners.
915    o pkg/generic_advdiff:
916     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
917      loop range indices for computing vertical advection tendency
918      and do the calculation in the interior only (no overlap) ;
919      for now, only implemented for SOM advection (to save CPU time).
920     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
921    o exch2 adjoint
922      First set of changes:
923      - add exch2 hand-written adjoint templates
924      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
925        This will require cleanup in pkg/autodiff/*.F
926        (changed routines currently kept separate in verif. code/)
927      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
928        that used to hide exch2 or cubed-sphere specific code
929        (commented via 'cph-exch2')
930    o pkg/seaice
931      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
932    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
933       output of global_ocean.cs32x15.thsice .
934    
935    checkpoint59e
936    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
937      for B-grid vector (not yet tested) and C-grid vector (<- only used
938      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
939    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
940      (#ifdef ALLOW_SALT_PLUME)
941    o gather_2d/scatter_2d: removed halo regions
942    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
943      scheme and the corresponding test case (under front_relax dir). For now,
944      only available with Skew-flux form and not yet tested in realistic set-up.
945      adjoint: store directives updated, but gradient checks deteriorated,
946      so maybe GM/Redi adjoint is now broken.
947    o seaice adjoint
948      * add AREA, HEFF, HSNOW as control variable
949        (should not change lab_sea results)
950      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
951    o pkg/seaice:
952      * added computation of saltFlux in seaice_growth;
953        For time being, sea ice salinity is assumed constant
954        contribution of snow flooding to freshening of sea ice is neglected.
955        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
956        defaults to 0.0 in order to maintain backward compatibility.
957        Typical values for SEAICE_salinity are 4 to 10 g/kg.
958      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
959      * added SEAICE_availHeatFrac, which specifies fraction of surface level
960        heat content used to melt or grow ice
961      * commented out cap of HICE: it helps keep ice thinner
962      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
963      * applied OBCS T/S mask to HEFFM sea ice mask
964    
965    checkpoint59d
966    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
967     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
968     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
969    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
970     and change default value of parameter "GM_Small_Number";
971     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
972       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
973       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
974    o pkg/ecco: cost function when applying pkg/smooth to controls
975    o pkg/ctrl: add forcingPrecond run time parameter
976    o pkg/seaice:
977     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
978     - fix bug in metric terms of u-equation in LSR solver (implicit part),
979       changes verification/lab_sea
980     - rearrange implicit part of u-equation in LSR solver to make it easier to
981       read, understand, and debug. This causes changes at the truncation level.
982     - fix (serious) bug in the boundary conditions (sign error in the implicit
983       part) of the LSR solver. Changes all LSR results.
984     - fixed problem with HSNOW initialization to avoid thick snow when AREA
985       is initilized with small values - does not change lab_sea results.
986     - added HsnowFile initialization capability
987    o pkg/smooth: addition to model/src and pkg/ctrl so allow
988     initialization of pkg/smooth and application to control vector
989    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
990    o dependencies: pkg/profiles requires pkg/cal
991    o pkg/profiles:
992     - added option ALLOW_PROFILES_GENERICGRID
993         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
994         that interpolation information (grid points and coefficients) is provided
995         within the netcdf input files.
996         -> sample matlab scripts can be found in MITgcm_contrib/gael
997         that allow you to prepare netcdf input files.
998     - also modified: cleaner include statements, cleaner error print statements,
999       cleaner stops when error, and more tests of the netcdf input files consistency.
1000    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1001    o pkg/seaice:
1002     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1003       requires a new routine: seaice_diagnostics_fill.F
1004     - make sure that seaice does not move if not forced (pressure replacement
1005       method, Hibler and Ip, 1995), changes results
1006     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1007     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1008       It is turned off by default (=-1.), because it changes the results.
1009     - make it possible to read AREA from a file, too.
1010    
1011    checkpoint59c
1012    o add S/R and diagnostics for oceanic mixed-layer depth
1013    o move GMRedi call after all vertical mixing schemes (including KPP)
1014    o pkg/thsice:
1015     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1016      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1017    o pkg/obcs:
1018     - bug fix for balance code
1019    o pkg/seaice:
1020      - allow values of SEAICE_elasticParm > 1
1021      - add new parameter SEAICE_evpTauRelax as an alternative
1022        to SEAICE_elasticParm
1023      - make lsr boundary conditions free slip (by default), changes result
1024      - add code for no slip boundary conditions for lsr
1025      - set minimum of zeta to zero (and not 4e8) (changes results)
1026      - add a cap on AREA after advecting AREA if seaice_growth is not called
1027    o change calculation of Visbeck K:
1028      - no longer depend on tapering scheme; instead, compute slope (limited
1029        by GM_maxSlope). this is equivalent to what was comuted before with
1030        clipping or linear tappering.
1031      - fix vertical averaging (wrong by 1/2 level)
1032      - leave the old version (but will not be maintained) within
1033        #ifdef OLD_VISBECK_CALC / #endif
1034      - update output of exp. ideal_2D_oce
1035    o change error catch in calc_r_star to improve vectorization
1036    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1037      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1038    o adjoint:
1039      Re-organized adjoint checkpointing according to Matt Mazloff
1040      (but with modifs/completions/cleanups)
1041      Storing is now bundled into large arrays to optimized I/O
1042      (and second step in cleanup of the_main_loop)
1043    
1044    checkpoint59b
1045    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1046      - export/import (between ocean & coupler) fields needed for ocean DIC.
1047    o pkg/seaice:
1048      - get rid of three more exchanges seaice_calc_viscosities (required
1049        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1050      - bug fix in seaice_ocean_stress (update of lab_sea required)
1051      - reduce loop boundaries to necessary minimum also in seaice_evp
1052      - go back to the old way of computing deltaC/Z as the adjoint likes that
1053        better
1054    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1055      passive tracer to an Age Tracer) + update output.txt
1056    o pkg/exf:
1057      - implement A-grid / C-grid selection for wind-stress input files.
1058      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1059      for now, in exf_bulk_largeyeager04.F only :
1060      - change implementation for case where windspeed + 2. components wind-stress
1061        are read-in. AND use rhoConstFresh to convert evap.
1062    o pkg/seaice:
1063      - use correct EXCH_UV for wind-forcing (on A-grid).
1064      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1065        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1066    o pkg/exf:
1067      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1068      EXF_INTERPOLATION:
1069      - merge global_with_exf/code version of exf_interp_read.F
1070        to the main code ;
1071      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1072        reading the file ; Important: This options needs to be defined to recover
1073        previous code.
1074        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1075      - no longer loose real*8 precision along the way when using exf_iprec=64.
1076    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1077      - change discretisation of evp-solver in order to avoid another exchange
1078        (changes lab_sea) and clean up a little
1079      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1080        help the adjoint (this also changes the results slightly)
1081      - add a few "_d 0" where they had been missing in seaice_evp.F
1082      - cleaning up: remove unused seaice_calc_rhs.F
1083    o pkg/exf: some cleaning-up:
1084      - change various "constants" into runtime parameters
1085      - cleaned-up Large&Yeager04 routine which should eventually
1086        replace exf_bulkformulae.F (changed names of S/R and CPP)
1087        and merged various ALLOW_ATM_WIND options
1088     only used with thsice pkg (in thsice_get_exf.F):
1089      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1090        which are used when useStabilityFct_overIce=TRUE (= the default)
1091      - change default values of ice & snow emissivity and scale downward LW
1092        by ice & snow emissivity.
1093    o pkg/thsice:
1094     fix few little problems, in thsice_calc_thickn.F:
1095      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1096      - melt only laterally if hIce < hThinIce (as the comments say)
1097      and in thsice_extend.F:
1098      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1099      - start to form ice as soon as the minimum ice-volume is reachable.
1100     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1101      and cpl_aim+ocn
1102    o pkg/kpp
1103     - move computation of surface related input fields to KPP into a new
1104       subroutine kpp_forcing_surf.F
1105     - remove wrong (within bi,bj loops) EXCH calls.
1106     - little cleaning (add argument myThid in last position, cvs header ...)
1107     - for now, fix conservation problem by exchanging KPPviscAz (may not
1108       be the best fix)
1109    o pkg/seaice
1110     - check for inconsistent evp parameter/cpp-flag combination
1111     - remove leftover errIO flat for obsolete name list error handling
1112    o OpenAD
1113     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1114    
1115    checkpoint59a
1116    o pkg/seaice: some parameter clarifications and a little bit of clean up
1117    o pkg/thsice: rename run-time parameters:
1118       himin       -> hIceMin
1119       himin0      -> hThinIce
1120       hihig       -> hThickIce
1121       i0          -> i0swFrac
1122       transCoef   -> bMeltCoef
1123       frac_energy -> fracMelting
1124      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1125       with default values (for now) that do not change the results.
1126      remove old version of thsice vars advection in pkg/seaice.
1127    o in FFIELDS.h:
1128      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1129      - make pLoad & sIceLoad always available (but still only used if
1130         ATMOSPHERIC_LOADING is #define).
1131    o pkg/kpp: replaced _KPP_RL with _RL
1132    o bug fixes for vertical diffusivity computations when both KPP and
1133        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1134        are no longer updating the vertical diffusivity array
1135        (passed as argument) but are (re-) setting those arrays.
1136    o pkg/seaice: fix bug in evp solver, while doing that
1137      - change (improve?) discretization of stress computations for both
1138        cgrid-lsr and evp solver
1139      - add a new routine to compute strain rates
1140      - the above changes lab_sea results
1141      - add no slip conditions for evp solver (off by default), lsr-version
1142        may follow
1143      - fix exchange for shear at Z-points (does not change lab_sea)
1144      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1145        (to force the user to pick a time step since there is not "safe" way
1146        of choosing it)
1147      - add principal stress diagnostics
1148      - rearrange fields for evp a little to avoid having to call a: too many
1149        exchanges and b: exchanges for stress trensor components which we do
1150        not have.
1151      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1152        of evp, complete rewrite for lsr case (latter is does not yet work
1153        in all cases)
1154    o pkg/kpp: add code to have mixing in shelf ice caverns
1155      - add myThid to all kpp routines (long overdue)
1156    
1157    checkpoint59
1158    o pkg/exf:
1159      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1160        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1161      - move exf header files from lower_case.h to UPPER_CASE.h ;
1162        add missing cvs Header & Name
1163      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1164      - add namelist param. selectStressGridPosition, exf_monFreq
1165      - retire many _CLIM routines, and remove data.exf_clim
1166        + params moved to data.exf
1167        + climsst, climsss now handled by exf_set_gen, i.e.
1168          climss?period=0 refers to constant field,
1169          climss?period=-12 to monthly forcing
1170      - split up namelists in data.exf
1171    o pkg/seaice:
1172      - remove seaice_exch and seaice_exch_uv
1173      - remove superfluous exchange of theta
1174      - add myThid to seaice_budget_ocean/ice
1175      - add new interface for atmospheric wind forcing (C-grid only)
1176        + new routine
1177        + two new field (taux, tauy for stress over ice)
1178        + removed one global field (DAIRN) for C-grid case only
1179    o pkg/thsise
1180      - 2nd set of modifs for thsice adjoint in conjunction with exf
1181    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1182    
1183    checkpoint58y_post
1184    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1185      vertical diffusivity, similar to that in MOM4; turned on using
1186      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1187      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1188    o Added capability for 3D specification of background vertical diffusion
1189      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1190      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1191      "data" file that contains the 3D vertical diffusivity coefficients.
1192    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1193      - add code within pkg thsice to advect & diffuse sea-ice fields
1194      similar to (and will replace) what has been added in  seaice_advdiff.F,
1195      but: - conserving Mass, Heat & Salt.
1196           - better when using non-linear advection scheme (not yet fully tested)
1197           - can also be used in atmospheric set-up (for now, only the diffusion).
1198    
1199    checkpoint58x_post
1200    o IO option for global-file compact format:
1201      - add options when generating topology (utils/exch2/matlab-topology-generator)
1202      - add I/O capability (pkg/mdsio).
1203      - adapt utils/matlab/rdmds.m to read this format.
1204      for now long-line format not yet supported by pkg/mdsio (& exch2).
1205    o shelfice: add a few diagnostics
1206    
1207    checkpoint58w_post
1208    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1209      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1210      (and replace horiVertRatio in NH code).
1211      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1212                         and tutorial_plume_on_slope (sensitive to truncation)
1213    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1214      directly to drive seaice model (C-grid only)
1215    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1216     - reintroduce computation of wind from stress,
1217     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1218       mass points to avoid tau = 0
1219     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1220    o rdmnc.m: make it work with "global" files created with gluemnc
1221    o rdmnc.m : some improvements in dealing with singleton dimension
1222      (tested on all testreport mnc output files).
1223    o genmake2: disable pkg/profiles if netcdf test fails.
1224    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1225    o move call to cal_readparms up to make calendar parameters/variable available
1226      to all packages
1227    
1228    checkpoint58v_post
1229    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1230      useDynP_inEos_Zc tested.
1231    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1232    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1233      and portions thereof.  See read_cs.txt for description and examples.
1234    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1235      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1236      following the great-circle arc between those 2 points.
1237    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1238      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1239    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1240     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1241     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1242     - still needs work (not working with some options ; efficiency to improve)
1243       and serious testing.
1244     - use this scheme for temperature & salinity in 2 advection test exp.:
1245       advect_xy & advect_xz, respectively.
1246    
1247    checkpoint58u_post
1248    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1249    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1250    o testreport: add option "-skipdir" to skip some test.
1251    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1252      momentum calculation.
1253    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1254    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1255      remove checkpoint.F and the_correction_step.F (no longer used);
1256      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1257    o add option (linFSConserveTr) to correct for tracer source/sink due to
1258      Linear Free surface
1259    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1260    o pkg/thsice: fix reading mnc-pickups
1261    
1262    checkpoint58t_post
1263    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1264    o pkg/mdsio:
1265     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1266       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1267       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1268     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1269     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1270       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1271     - new S/R (to replace MDSWRITEMETA), which allows to write more
1272       informations (variable names, time ...) to meta files.
1273     - modify rdmds.m to give back the meta file content.
1274    o pkg/diagnostics: change vertical interpolation to be safer, and more
1275       flexible (define p-levels to interpolate to in data.diagnostics);
1276      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1277       diagnostic pointer.
1278    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1279    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1280    o fix multi-category seaice:
1281     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1282       SEAICE_MULTICATEGORY
1283     - fix short wave heat flux
1284    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1285       and allow to use EVP solver. Change forward lab_sea: test both EVP
1286       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1287    o Initial check-in of lab_sea adjoint
1288      (very similar to natl_box_adjoint/code_seaice)
1289      * used C-grid and EVP solver
1290      * used KPP, GM/Redi
1291      * uses inAdExact=.TRUE.
1292      * gradient checks fail for both ADM and TLM
1293        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1294        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1295        issue is related to forward mismatch between g77 an ifort
1296    o pkg/seaice: overhaul of thermodynamics
1297     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1298     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1299     - move a few global fields out of SEAICE.h into seaice_growth.F and
1300       make them 2D (FICE/QNETO/ ...)
1301     - remove FO (it is the same as QNETO)
1302     - introduce a few local fields to avoid modifying external fields such
1303       as atemp, etc.
1304    
1305    checkpoint58s_post
1306    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1307      changed exf_set_gen.F so that
1308        genperiod=0 means input file is one time-constant field and
1309        genperiod=-12 means input file contains 12 monthly means
1310    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1311      this affects truncation error ; generate new output file for exp. which
1312      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1313        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1314        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1315        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1316        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1317        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1318    o start implementation of deep-atmosphere and anelastic formulation
1319    o verification: remove 2nd copy of input files and use script "prepare_run"
1320      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1321    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1322    o profiles: fix for multithreaded case
1323    
1324    o diagnostics: rename few diags:
1325      s/'PRESSURE'/'RCENTER '/g
1326      s/'TICE    '/'oceFreez'/g
1327      s/'TAUX    '/'oceTAUX '/g
1328      s/'TAUY    '/'oceTAUY '/g
1329      s/'SWFLUX  '/'oceQsw  '/g
1330      s/DIFx/DFxE/g
1331      s/DIFy/DFyE/g
1332      and add few ocean-forcing diagnostics:
1333      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1334    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1335      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1336      as actual snow thickness.  It now refers everywhere to effective snow
1337      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1338    
1339    checkpoint58r_post
1340    o modifications to pkg/seaice/growth.F, which change results of
1341      lab_sea experiment: fixes pertain to melting snow over open water, to
1342      masking EVAP under sea ice, and to using the correct AREA variable for
1343      computations of EVAP, PRECIP, HSNOW, and GHEFF
1344    o add ability to read bathy, salt, and theta using MNC (off by def)
1345    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1346      both are turned off by default and do no change any results
1347    o seaice advection with pkg/thsice: a step toward the use of non-linear
1348      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1349    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1350      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1351      in natl_box (affects results @ truncation level: update output.txt)
1352    o multi-threading and IO:
1353      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1354      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1355        (needed to work with SingleCpuIO): tested in all verif. exp.
1356    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1357      affects the results (but none of the verification test uses this scheme).
1358    o Adding some pkg/diagnostics capability to pkg/seaice
1359      (will certainly be subject to changes)
1360    o ctrl: adding new control variables:
1361      lwflux, lwdown, evap, snowprecip, apressure, runoff
1362    
1363    checkpoint58q_post
1364    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1365      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1366      high_res_cube configuration by 4% on Columbia.
1367    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1368      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1369      dynamical allocation (seems to work in multi-threaded).
1370    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1371      single CPU io) so that TAF does not have to see EESUPPORT.h
1372    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1373    
1374    checkpoint58p_post
1375    o obcs: stop if obcs is used with useCDscheme = .true.
1376    o shelfice:
1377     - fix a sign error so that no slip at shelfice interface works
1378     - remove stop for combination non-hydrostatic code and shelfice. That does
1379       not mean, that the results are correct, but at least they are numerically
1380       stable
1381    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1382    o added adjoint exch routined for all exch*3d* routines
1383      and updated flow directives
1384    
1385    checkpoint58o_post
1386    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1387      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1388    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1389      and clean-up reading/writing of pickup files.
1390    o fix local version of read/write pickup (NH part) in rotating_tank/code
1391    o simplify EXCH interface:
1392     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1393     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1394    o added the regrid package
1395    o shelfice:
1396     - add a simple boundary layer scheme to reduce noise
1397     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1398    
1399    checkpoint58n_post
1400    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1401       local variable (not in common block).
1402    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1403      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1404      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1405        to work with SingleCpuIO.
1406    o add "_d 0" to real constant of pkg/cfc subroutines ;
1407       update exp. cfc_exemple & tutorial_cfc_offline output files.
1408    o multi-threading and IO:
1409      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1410        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1411      - barrier before and after reading.
1412      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1413      - avoid using MDS_WRITELOCAL for LAND pkg output.
1414      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1415        common-block variables ; Allows multi-threading with master-thread IO.
1416    o change default MAX_NO_THREADS from 32 to 4 ;
1417      and stop cleanly when MAX_NO_THREADS is too small.
1418    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1419    
1420    checkpoint58m_post
1421    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1422       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1423    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1424       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1425       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1426    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1427        add MITgcm_tutorials (= code + all the tutorials)
1428    o ecco, option to compute cost for total ssh (mean+anom)
1429    o consistent with addition of ptracer and ssh in pkg/profiles
1430    o profiles: adding ptracer and ssh
1431    o testreport: change multi-test output-file name
1432      (from output.txt.{name} to output.{name}.txt)
1433    o profiles: now ok for mutli-tiles case
1434    o seaice: add 4 parameters for different advection schemes for area,
1435      (effective) seaice thickness, enthalphy, and snow height. Their default
1436      is the standard parameter SEAICEadvScheme
1437    o calc_gw:
1438     - add cosFacU in zonal viscous flux (harmonic.visc.).
1439     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1440       of tutorial_plume_on_slope.
1441    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1442    o calc_gw: true flux-form, account for horizontal grid spacing.
1443      update rotating_tank results, but not plume_on_slope (affected at
1444      truncation level, 11 digits).
1445    
1446    checkpoint58l_post
1447    o calc_gw:
1448     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1449     - remove side-drag for now (need to fix it); update plume_on_slope results.
1450     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1451    o commit code to make SST/SSS weights spatially variable
1452      (based on either variable in-situ or variable initial T/S weights)
1453    o pkg/ecco:
1454      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1455        now based on horizontally varying weights wthetaLev, wsaltLev
1456      * cost_averagesflags now returns year indices in addition to day, month
1457      * sflux balance is performed on annual basis
1458        (sflxumm, sfluxmm2, bal_sfluxmm)
1459      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1460        including separate counting and multipliers
1461    o pkg/rbcs
1462      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1463    
1464    checkpoint58k_post
1465    o testreport:
1466     - always build in dir. "build" (if not there, mkdir build instead of building
1467       & running in input)
1468     - run in dir run (if it exists), in build otherwise.
1469     - call prepare_run (if input/prepare_run exists)
1470     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1471    o pkg/exf modifications to interpolation and rotation routines for more
1472       reasonable treatment of North Pole singularity: for tracers North Pole
1473       value is set to northernmost zonal-mean value, for zonal velocity it is
1474       set to zero, and for meridional velocity it is set to northernmost value.
1475    o pkg/exf/exf_check_range.F
1476     - add tile index to diagnostics and move stop statement to the very
1477       end of the routine.
1478    o pkg/diagnostics: (diagnostics_main_init.F)
1479      define title of isomorphic variables according to the current config.
1480    o pkg/thsice with pkg/seaice dynamics:
1481    - fix domain of computation (interior only, required for exf) and do exchanges
1482    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1483    o towards a standard way of dealing with multi-threading in MONITOR
1484      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1485    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1486       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1487    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1488    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1489    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1490       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1491    o tracer advection:
1492     - clean-up and simplify calc_common_factors.F
1493     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1494       advection subroutine (but still not used within DST advection S/R)
1495    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1496    
1497    checkpoint58j_post
1498    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1499      from file (collects calls previously in FORWARD_STEP)
1500    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1501    o adjoint store dir. adjusted accordingly
1502    o genmake2
1503      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1504    
1505    checkpoint58i_post
1506    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1507      on wind stress (SEAICEstressFactor defaults to 1.)
1508    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1509      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1510    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1511      on CS-grid: no longer loosing mass.
1512    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1513    o pkg/ggl90: fix sloppy output and fix a bug
1514    o pkg/seaice: added SEAICEuseEVPpickup parameter
1515      - Set to false in order to start EVP solver with
1516        non-EVP pickup files when using SEAICEuseEVP
1517      - fix sign error in diffusion in seaice_calc_rhs
1518    
1519    checkpoint58h_post
1520    * Modifications for bottom topography control
1521      o replace hFacC by _hFacC at various places
1522      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1523      o add non-self-adjoint cg2d_nsa
1524      o update autodiff support routines
1525      o re-initialise hfac after ctrl_depth_ini
1526      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1527    * Adding verification for 5x5 box (4-layer) bottom topography control
1528    
1529    checkpoint58g_post
1530    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1531       used for mean seasonal cycle, mean diurnal cycle); add an example
1532       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1533    o pkg/ggl90:
1534      - add parameter (minimum surface kinetic energy)
1535      - fix bug (avoiding division by zero)
1536    o couple pkg/thsice to pkg/seaice:
1537      - modify advection in seaice to accomodate new scalar fields to be advected
1538      - only muliDimAdection scheme work with seaice/thsice
1539      - mapping of thsice-variables to seaice-variables, back and forth
1540      - does not break the verification experiments, but does not give the
1541        desired results either
1542    o pkg/seaice
1543      - make (default) second order advection a bit less confusing?
1544    
1545    checkpoint58f_post
1546    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1547      to pkg/seaice):
1548      - new routines thsice_map_exf and thsice_get_exf provide the interface
1549      - add an additional formal parameter to thsice_solve4temp
1550    o pkg/exf:
1551      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1552      - correct Stefan-Boltzmann constant
1553      - new parameter for longwave surface emittance
1554      - separate some stuff from exf_bulkformulae into new routines  
1555        exf_radiation, exf_wind
1556      - add new parameters and constants: longwave emissivity for ocean, ice
1557        and snow, evaporation parameters over ice
1558      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1559        either wind from stress or stress from wind
1560    o pkg/thSIce:
1561    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1562    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1563       and THSICE_CALC_THICKN
1564    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1565    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1566      to make debugging easier.
1567    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1568    o pkg/bulk_force:
1569      - clean-up comments and parameters ;
1570      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1571    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1572      generate new output for test-experiment: aim.5l_cs.thSI
1573    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1574      testreport accordingly
1575    
1576    checkpoint58e_post
1577    o SEAICE_CGRID adjoint done
1578    o R_STAR adjoint implemented.
1579      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1580      * need to sort out init. of h0facc, etc.
1581    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1582      to be able to use it in pure forward.
1583    
1584    checkpoint58d_post
1585    o upgrade simple test-experiment to tutorial example:
1586     step.1: duplicate the experiment and (step.2) will remove the old copy.
1587      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1588      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1589      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1590      tutorial_global_oce_biogeo    <- copy of dic_example
1591      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1592      tutorial_plume_on_slope       <- copy of plume_on_slope
1593      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1594      tutorial_global_oce_optim     <- empty for now (David ?)
1595      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1596     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1597    o correct a sign problem in cost_scat.F
1598    o obcs and ptracers: fix boundary conditions for advections schemes
1599      with larger stencil
1600    o thsice adjoint: start
1601    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1602      completeness
1603    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1604      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1605    o ptracers adjoint:
1606      * avoid extensive recomputatations
1607      * fix missing re-init. of gptr (missed by TAF)
1608    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1609      me to turn off the excessive output to STDOUT that this package produces
1610    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1611      and add those terms in Vector-Invariant formulation.
1612    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1613      if the control period (xx_hfluxperiod etc) is 0
1614    o in profiles pkg, clean routines and fix details
1615    o in ecco pkg, reading ssh data:
1616      fix problem in case the model does not start at iter0=0
1617    o fix mnc-pickup/restart for ptracers
1618    o new package prifiles:
1619      code to compute profile-based cost by Gael Forget
1620      (modifs in ecco, ctrl, autodiff)
1621    o Benign bug fix in initialization (spotted by M. Mazloff) of
1622      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1623    
1624    checkpoint58c_post
1625    o adjoint: finish NLFS adjoint and provide reference output in
1626      verification/global_ocean.90x40x15/results_ad_nlfs
1627    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1628      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1629      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1630      with SEAICE_CGRID defined.
1631    o move calendarDumps from "data" to "data.cal" and clean-up the code
1632      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1633    o add useEXF & useCAL flags (for now, set in hard-coded way)
1634    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1635      (were missing in NH mode, and wrong in quasihydrostatic mode).
1636      waiting for Chris updated version of calc_gw to add those CALLs.
1637    o fix bug in quasihydrostatic S/R ;
1638      add a test for this option: global_ocean.90x40x15.qshyd
1639    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1640      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1641    o add on/off flag useOffLine for package OFFLINE
1642    o seaice:
1643      - modify advection so that it works also on the C-grid
1644      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1645        problem in multi-tile runs with C-grid
1646      - add flags for clipping ice velocities and/or masking solver forcing
1647      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1648        C-grid solver
1649      - added a few comments to seaice_diffusion.F
1650      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1651        are now exclusive)
1652      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1653        required re-ordering the code a little:
1654       + make DAIRN global variable (defined in SEAICE)
1655       + move computation of the viscosities eta and zeta into a new separate
1656         routine (because I need to recompute them in seaice_ocean_stress.F)
1657    
1658    checkpoint58b_post
1659    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1660      update output.txt of exp. aim.5l_cs.thSI
1661    o various mnc cleanups and improvements:
1662      + shrink lookup tables by factor of ~4
1663      + better error reporting when running out of lookup space
1664      + able to handle longer path/file names (up to 500 chars)
1665    o adjoint:
1666      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1667      - TBD: "hidden" mom_vecinv recomp. in dynamics
1668    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1669     (allow to differentiate between forcing components using new integer flags:
1670      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1671     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1672    o ecco
1673      - enable trend removal from SSH anomaly obs.
1674    o adjoint
1675      - a fix for PmEpR when #undef EXACT_CONSERV
1676      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1677      - try to fix "hidden" recomp. in forward_step for NLFS
1678        (NLFS seems broken sometimes after I checked it in)
1679    o seaice:
1680     - add c-grid version of the dynamic solver:
1681       + three new routines that are the c-grid substitute lsr, dynsolver
1682         and ostres
1683       + put a few fields that were local to dynsolver into global common
1684         blocks, so that I can move the computation of stresses etc into
1685         seaice_lsr (saves coding but may break the adjoint).
1686     - replace more hardwired parameters by runtime parameters
1687     - add ice masks that mask the rhs of the implicit solvers where there
1688       is no ice (commented out in seaice_dynsolver, because i am not sure
1689       if this works properly), eventually this should replace the clipping
1690       of ice velocities in seaice_dynsolver to +/-40cm/s.
1691    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1692      include it only where its needed
1693    o move balancing of fluxes before the call of external_forcing_surf
1694    o seaice:
1695      - correct units of turning angles (now they are really in degrees)
1696      - move computation of GWATX/Y out of main routine into dynsolver
1697      - initialize GWATX/Y in seaice_init
1698    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1699      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1700    o seaice: add runtime flags for turning angles (default to zero)
1701    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1702      and trend from exf forcing and ctrl control adjustments
1703    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1704      (since checkpoint57x_post)
1705    o change the default rotation period to 86164.s = the Earth rotation
1706    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1707      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1708    o seaice advection: add code for choosing between the default (2nd order
1709      central differences) and multiDim advection schemes provided by
1710      pkg/generic_advdiff
1711    o seaice:
1712      - removed all references to SEAICE_GRID.h fields from
1713        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1714        (cubed-sphere configuration will change a little)
1715      - grid computations in seaice_init are obsolete now.
1716      - cleaned up code a little so that is easier to read (hopefully).
1717      - added new (better?) discretizations of default advection and diffusion
1718        (turn on with SEAICEuseFluxForm)
1719      - replace 1 in 3d global fields by kSurface in growth.F
1720      
1721    checkpoint58a_post
1722    o seaice:
1723      - bug fix in advect.F
1724    o shelfice:
1725      - separate shelfice load anomaly from pload (breaks with time
1726        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1727        Its default is 0., but it may be computed more cleverly from (unknown)
1728        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1729        done offline. A good approximation of the pressure load anomaly is
1730        necessary to avoid large initial adjustment processes underneath
1731        deep-reaching shelfice.
1732      - small fix in ISOMIP shelfice_thermodynamics
1733      - add more sophisticated thermodynamics of Hellmer (1989), this is
1734        now the default
1735      - give a few constants more intuitive names
1736    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1737      if bulk formulae are used in long integration (especially EmPmR). Turn
1738      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1739      if balancePrintMean, the imbalance that is substracted is printed to
1740      STDOUT.
1741    o fix bug (typo) in obcs_apply_eta.F
1742    o add a new package shelfice which enables us to model the circulation
1743      underneath shelf-ice with draughts of hundreds of meters.
1744     - works
1745     - to do: + include improved thermodynamics
1746              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1747                instead of new field kTopC
1748              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1749                instead of new field R_shelfIce and new code in ini_depth.F
1750                and ini_mask_etc.F?
1751              + adjust vertical mixing schemes?
1752    o seaice pkg:
1753     - add a cpp-flag to include a simple formula for a salinity dependent
1754       freezing point of sea water at the surface
1755     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1756       meridional stresses are now different (and hopefully correct)
1757    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1758       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1759       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1760    o pkg/diagnostics: add options and parameters for regional-statistics
1761       diagnostics ; define regions by reading a region-mask from a file
1762       (might add other options later)
1763    o pkg/bulk_force:
1764     - add option and parameters to use AIM surface-flux formulae.
1765     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1766       others forcing fields (defined in PARM05, parameter file "data") are loaded
1767       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1768     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1769     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1770     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1771       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1772     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1773    
1774    checkpoint58
1775    o add "--embed-source" option to genmake2 which, when the supporting
1776      tools can be compiled (as determined by genmake2) will turn on the
1777      embed_files package which then embeds the entire MITgcm source code
1778      (*.[fFhc] + Makefile) used for the build within the executable
1779      - requested by CNH but off by default
1780      - adds a paltry <9MB to the mitgcmuv executable in most cases
1781      - only writes the output when useEMBEDSRC in eedata is true
1782    o clean up 3-dim. relaxation codes:
1783      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1784      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1785      * Thanks to Tom Haine for testing!
1786    
1787    checkpoint57z_post
1788    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1789      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1790    o fix the pickup behavior for obcs in combination with ptracers
1791    o fix a bug in ptracers_external_fields_load
1792    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1793      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1794    o transfered surface NH pressure to eta field (if exactConserv).
1795    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1796         and update lab_sea output.txt file.
1797    o completing 3-dim. relaxation code: additional term
1798         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1799      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1800      * At compile time, in "EXF_OPTIONS.h" set
1801          #define  ALLOW_CLIMTEMP_RELAXATION
1802          #define  ALLOW_CLIMSALT_RELAXATION
1803      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1804          tauThetaClimRelax3Dim = 15552000.0,
1805          tauSaltClimRelax3Dim  = 15552000.0,
1806      * 3 cases:
1807          1) Use a constant-in-time 3-dim. field
1808          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1809          3) Real-time relax. to time-evolving prescribed field
1810    o Adding Laplacian-type smoothness constraint on
1811      initial and boundary (forcing) controls (ic, bc)
1812      * enable at compile-time via
1813        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1814      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1815      * Absolute scale somewhat unclear so far
1816      * no area weighting was included since no other cost term does so far
1817    
1818    checkpoint57y_post
1819    First step for a NLFS adjoint
1820    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1821    o new init. routines for calc_r_star, calc_surf_dr
1822    o still need to deal with ini_masks_etc
1823    o testreport seemed happy
1824    checkpoint57y_pre
1825    
1826    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1827    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1828    o add new offset feature to offline pkg (plus minor cleanup)
1829    o cfc fixes for final year of integration
1830    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1831      be in GCHEM_OPTIONS).
1832    
1833    checkpoint57x_post
1834    o fix testreport Pb in multiple test experiment.
1835    o cleanup our namelist syntax in verification:
1836      - make it more F95 standards compliant (some work still needed)
1837      - allows the vast majority of our tests to work with gfortran
1838    o Non-Hydrostatic:
1839     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1840     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1841    o Allow to apply AB on T,S rather than on AB(gT,gS):
1842     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1843     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1844       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1845     - need a "clever" read_pickup to restart from the other AB formulation
1846    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1847    o remove some unused variables (reduces number of compiler warnings)
1848    o adjoint
1849      * Disable useVariableViscosity for adjoint for time being
1850        (there are a number of extensive recomputations)
1851      * Initialize certain variables needed for adjoint
1852    
1853    checkpoint57w_post
1854    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1855                 fix the singleCpuIO RS version of MDSWRITEFIELD
1856       and add a WARNING if using globalFiles=T with multi-processors.
1857    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1858      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1859    o tracer advection scheme:
1860      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1861       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1862       was not very convenient).
1863      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1864       (further tests needed for the implicit DST & Flux-Limiter schemes).
1865    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1866      and sRef for convenience, handy, when you want to initialize
1867      ptracers in a large domain with a constant non-zero value. Also,
1868      untangle ptracers_init.F a little.
1869    
1870    checkpoint57v_post
1871    o change dome exp. to use variable viscosity in side-drag terms.
1872    o remove all the files from the cfc_offline test since they are now
1873      incorporated into tutorial_cfc_offline which has been producing
1874      identical results for a few days of testing
1875    o add new parameter: sideDragFactor to enable half-slip-side BC
1876      and change side-drag S/R to use viscosity from mom_calc_visc
1877      (can switch back by setting sideDragFactor=0.); affects results at
1878      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1879       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1880    o vorticity & strain are now computed without masking, to account for
1881      no-slip-side BC in variable viscosity calculation ; mask is applied
1882      anyway later on, before computing advection/coriolis terms.
1883    o modify exp4 to test new obcs support for reading from external files
1884      and for passive tracers
1885    o fix behavior of ptracers_monitor when monitor output is written to a
1886      netcdf-file; still not independent of monitor.F (writes in the same
1887      file).
1888    o change default value of tRef (put a uniform, meaningful value for ocean
1889      & atmos) and initialize sRef (was missing, as Martin mentioned).
1890    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1891      to be proportional to enstrophy dissipation length.  Thus,
1892       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1893      This is now consistent with Smagorinsky and with the manual.
1894    
1895    checkpoint57u_post
1896    o OBCS and PTRACERS: add open boundary support for passive tracers
1897      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1898        OB-values from file; this is not different from the way theta and salinity
1899        are treated
1900      - however, Orlanski-radiation conditions are not supported, and the model
1901        will stop if you use pTracers and Orlanski at the same time.
1902      - beefed up the rountine obcs_external_fields_load: now only those open
1903        boundary values are overwritten with values from files for which there
1904        are really files, otherwise the OB-fields remain untouched. This makes
1905        it possible to use different OBs at different ends of the domain (as
1906        with EXF)
1907    o reduce number of exch calls in shap_filt (s2).
1908    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1909      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1910    
1911    checkpoint57t_post
1912    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1913    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1914      same truncation, independent of the face number: affects affects several
1915      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1916    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1917      note that biharmonic viscosity + no-slip was not tested in any experiment.
1918    o fix bug in non-linear free-surf side-drag ; generate new output for
1919      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1920    o make mnc honor the writeBinaryPrec flag for most kinds of output
1921    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1922    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1923      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1924    o add brackets in multi-terms sum to get same truncation, independent of
1925      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1926      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1927    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1928      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1929      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1930      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1931      Suggested values of viscosity parameters found in mom_calc_visc.
1932      Many new viscosity diagnostics available.
1933    
1934    checkpoint57s_post
1935    o Add clearing-house for viscosity calculations, mom_calc_visc and
1936      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1937      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1938      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1939      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1940      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1941      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1942      ViscAhStrain and viscAhTension are now retired.
1943    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1944    o In response to JMC's bug report, genmake2 now ignores any soft-links
1945      that it finds in the *current* directory when searching for files.
1946      Soft-links found in any other source directories will still work as
1947      they did before.
1948    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1949      a C routine to unlimit the stack size
1950    o mnc-ify pkg/aim snapshot vars
1951    o mnc-ify pkg/land as requested by Daniel
1952    o various changes to mnc including:
1953      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1954      - output can now be grouped so that all files within a group
1955          change the ITER portion of their names in lock-step together
1956      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1957          and works with both EXCH1 and EXCH2 (but needs more testing)
1958      - writing works for all verification test cases w/ g77 on Linux
1959    
1960    checkpoint57r_post
1961    o make MNC variable initialization happen earlier
1962    o add diagnostics for (almost) each term of the momentum Eq.
1963    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1964    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1965    o remove MINIMAL_TAVE_OUTPUT option ;
1966      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1967    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1968      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1969    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1970    o add time-dependent SST, SSS control
1971    o cost terms in ecco/ modularized (new cost_generic.F)
1972    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1973    o new infrastructure for seaice model vs. obs misfits in seaice/
1974      * driver from the_main_loop.F is seaice_cost_driver.F
1975      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1976      * gradient check in Exp. 6a of natl_box_adjoint/
1977    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1978      (see README file)
1979    
1980    checkpoint57q_post
1981    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1982    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1983      - bug was reported by Jean-Michel and Ian Fenty
1984    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1985      update exp. cpl_aim+ocn output.
1986    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1987      Needed for high-res. runs with large global files
1988      to be able to limit tapelev size
1989    o Changed some tests for adjoint:
1990      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1991      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1992      * global_ocean.90x40x15/ back to default 3-level checkpointing
1993    o Modifications to enable scripted COMMON to MODULE conversion
1994      * verification/OpenAD/code/ has necessary scripts and description;
1995      * converts, compiles and runs successfully;
1996    
1997    checkpoint57p_post
1998    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1999    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
2000      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
2001    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
2002    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
2003      (was already the case for dissipation with mom_vecinv,
2004       and also the case for grad.PhiHyd when staggered-timeStep)
2005      This will allow to put dissipation out-off the AB time-stepping.
2006     Unfortunately, affects truncation error. Update output of exp. that "fails"
2007      (cg2d matching number) and leave the others for later: front_relax(10),
2008      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
2009      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
2010    
2011    checkpoint57o_post
2012    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
2013      (2) its ready to be documented during the 20050801 DocFest
2014    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
2015      for ideal_2D_oce and lab_sea on linux_ia32_g77
2016    o set to #undef CTRL_SET_OLD_MAXCVARS_30
2017      in global1x1_tot/code_seaice_adj to access indices 32, 33
2018      (worth another tag)
2019    
2020    checkpoint57n_post
2021    o adding precip control xx_precip 32
2022    o adding swflux control xx_swflux 33
2023    o Replacing 10 forcing penalty cost routines by 1 generic.
2024    o Implementing partitioning in time-mean and variable adjustment
2025      for atmos. state.
2026    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
2027  o in natl_box_adjoint:  o in natl_box_adjoint:
2028    * updated: results_bulk/    * updated exp 1 to 10
2029    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
2030    o updated global1x1/*_seaice_adj/
2031      to incorporate latest changes
2032    o enable useSingleCpuIO for mdsio vector routines
2033      (applies in particular to tapelev I/O)
2034    o removed inefficient K-loop in all active_file*control*.F
2035    
2036  checkpoint57m_post  checkpoint57m_post
