4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/mdsio (read/write field):
8     - tiled IO done in 1 piece (all levels at a time);
9     - multi-threaded: allow to read/write local (non-shared) array
10       (was already working with singleCpuIO ; now works also without);
11       => no longer needs barrier call after reading a file (added inside
12       mds_read/write field).
13     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
14     - move barrier calls outside gather/scatter_2d to mds_read/write_field
15    o pkg/obcs/exf
16      - exf_getffieldrec.F: add a few ". _d 0" and
17                            add code to catch the case fldperiod = 0.  
18      - obcs_precribe_read.F: change if statements so that they match
19                              the variable type (_RL)
20      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
21        exf_iprec) as part of namelist EXF_NML_01
22    o pkg/mdsio:
23      - read/write tiled (local) files: read/write 1-level tile chunk at a time
24        (instead of segment of length sNx); expected to speed up tiled IO.
25    o pkg/exch2:
26      - take buffer copy from/to array out of S/R exch2_send/recv into new
27        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
28        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
29      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
30      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
31        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
32        including Topology header file (and common blocks).
33      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
34        remove 2nd exch call in exch2_s3d_rx (no longer needed).
35      - document S/R arg. list (+ update some comments)
36    o pkg/seaice:
37      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
38        temperature and humidity over sea ice based on climatological values.
39      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
40        of LSR (this change is expected to change the results slightly because now
41        it uses slightly difference moduli from the second last LSR solution, but
42        that is more consistent with the stress computations; this part of the code
43        is not tested in the verification experiments)
44      - fix diagnostics for flux of ice in case of B-grid
45      - turn strain rates eij and press into global fields within global
46        common block in SEAICE.h for more straighforward diagnostics
47      - fix diagnostics for principal stress components, press, zeta, eta
48        to give something meaning full
49    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
50      new output (all 4 tests) using default rotationPeriod.
51    o pkg KPP:
52      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
53      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
54        and normal grid from 1 to Nr)
55    o Fix computations of L4rdt in mom_calc_visc.F
56    o eesupp:
57      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
58      should be called before a "stop" if we know that all process are going
59      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
60    
61    checkpoint61o
62    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
63    o model/src/ini_curvilinear_grid.F:
64       compute angleSin/CosC when they are not read from a file
65    o pkg/seaice:
66       add pseudo time stepping for LSOR
67    o pkg/exch2:
68       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
69    o pkg/seaice:
70       Adding separate sea ice albedo, drag coefficients, and HO in Southern
71       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
72    o SingleCpuIO:
73       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
74    o pkg/seaice:
75       put exchanged variable in (local) common block for MPI+Multi-Threads
76       to work (necessary with exch1, and for now with exch2 too).
77    o verification: to get more experiments tested with mpi, mth and mpi+mth,
78      change tiling of:
79       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
80       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
81      update output of exp:
82       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
83       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
84      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
85                       (note: output.txt generated on faulks using only 1 tile)
86    o eesupp & mdsio (SingleCpuIO):
87     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
88       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
89       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
90     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
91     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
92       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
93    o pkg/exch2:
94     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
95       read parameter file "data.exch2" if it exists; otherwise try default regular
96       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
97     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
98       with new code (not to be used, just as a backup solution).
99     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
100       in utils/exch2/input.
101    
102    checkpoint61n
103    o eesupp & mdsio (SingleCpuIO):
104      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
105        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
106        receive real*4 array (instead of real*8) to read/write 32.bit files.
107        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
108         and remove new mapping S/R)
109    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
110      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
111        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
112        when using exch2. Add S/R to map global io-buffer to global model array.
113      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
114    
115    checkpoint61m
116    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
117      and add 3 other S/R for other types (R4,R8,RS).
118      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
119    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
120     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
121     - reduce number of macro definitions (keep only those which are used);
122       can always call directly the corrresponding S/R if needed.
123     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
124       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
125     Fixed wrong type of arg in:
126       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
127       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
128     To fix: global_sum of var in common block is wrong (multi-threaded) in:
129       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
130     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
131    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
132      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
133    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
134    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
135      edges are closed (zero depth); might happen with "blank tiles";
136      for now, disabled if using OBCS.
137    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
138      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
139    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
140      to reduce length of 1.D array print in STDOUT.
141    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
142      + use 48 tiles (16x8): this will allow to test "blank tiles".
143    o start to test MPI + multi-threaded (change testreport to skip tests
144      where number of tiles do not match).
145    o genmake2: add option "-omp" to turn on Open-MP ;
146      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
147    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
148      and keep the original tile numbering. Note: compatible with old
149      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
150    
151    checkpoint61l
152    o Overlaps had been forgotten in calculating ijk keys : fixed
153    o fix cyrus makedepend for gcc 4.4
154    o experiment fizhi-cs-aqualev20:
155      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
156      and generate new output. Note: new output is much closer to the old
157      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
158      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
159    o pkg/fizhi:
160     - change to avoid indices going deliberately over array-bounds
161     - remove unnecessary MPI stuff
162     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
163     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
164       does not go over array-bounds and therefore returns reliable output.
165     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
166       this S/R has 4 output arguments, which are used inside "get_alarm";
167       when it is called with the same variable "ndum" in place of several
168       output arguments, this produces weird side effect inside "get_alarm"
169      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
170       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
171       address) and produces error.
172    o tools/gemake2: (March 27-29 2009)
173      with option "-mpi": link *_mpi files from "MODS" dir (this is what
174      testreport does).
175    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
176    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
177       update lab_sea.lsr & lab_sea.salt_plume results
178    o pkg/seaice:
179      Major overhaul of the LSOR solver: change discretization from original
180      finite differences to finite volume. The old routine is still in the
181      file seaice_lsr.F and can be turned on with the CPP-flag
182      SEAICE_OLD_AND_BAD_DISCRETIZATION
183      Along with this change, the discretization of the strain rates is changed.
184      The same flag turns on the old discretization in seaice_calc_strainrates.F
185      All verification experiments with seaice are affected (except for
186      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
187      results by setting the above flag.
188      Further changes involve changes in defaults:
189      - ALLOW_FLOODING is defined and turned on by default
190      - SEAICEadvSnow = .true. is now the default
191      - SEAICEadvSalt = .true. is now the default
192      - SEAICEadvAge  = .true. is now the default
193      - SEAICE_clipVelocities  = .false. is now the default
194                                         (as per J. Zhang's recommendation)
195      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
196        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
197      - seaice_growth: replace computation of UG by a simple copy from wspeed
198    
199    checkpoint61k
200    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
201      seaice_lsr: fixed a few metric terms,
202                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
203                  add more debugging diagnostics
204      seaice_evp: removed superfluous many metric terms of FV discretization
205                  of stress divergence
206                  affects lab_sea, lab_sea.hb87
207      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
208                  of stress divergence for non-evp solver
209                  (this part is not tested anywhere)
210      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
211                  they were effectively only half slip
212                  affects lab_sea.hb87
213      updated all relevant verification experiments (except lab_sea//output_adm.txt
214        which was left over, but fails at level 7 & 6)
215    
216    checkpoint61j
217    o pkg/seaice: turn a few hard wired parameters into run time parameters
218    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
219      time in seconds as promised by the usints in seaice_monitor and exf_monitor
220    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
221      that are not cubed-sphere grids
222    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
223    o pkg/ctrl:
224      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
225    o non-hydrostatic (calc_gw.F):
226      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
227      update output of exp. global_ocean.cs32x15.viscA4
228    o remove backward compatibility for thetaMin,phiMin
229      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
230    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
231      interpolated wind field not only for curvilineargrid=.true., but also
232      for a rotated grid (rotateGrid=.true.)
233    o pkg/exf: add capability to bypass interpolation for runoff
234      by setting yet another CPP-flag
235    o eesupp/src, B-grid exchange:
236      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
237    o autodiff
238      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
239      allows to switch to single-prec common blocks;
240      corresponding switch occurs in tamc.h, integer isbyte
241      TAF store directivs "byte" and "kind" seem equivalent;
242      Most tamc.h have been updated correspondingly.
243    
244    checkpoint61i
245    o autodiff:
246      fix autodiff_sore/_restore indices for obcs
247      (spotted by I. Hoteit, M. Mazloff)
248    o pkg/autodiff, pkg/ctrl:
249      Add flag to reduce all tapelev I/O to single-prec.
250      In data.ctrl set
251        doSinglePrecTapelev = .TRUE.
252    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
253      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
254    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
255      real fresh water flux (not yet)
256    o pkg/mdsio & rw:
257     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
258     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
259    o pkg/flt:
260     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
261       init_fixed & ini_varia.
262     - clean-up & simplify linear interpolation S/R:
263       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
264     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
265     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
266     - add vert. coordinate & horiz. indices to output files.
267     - change vertical position in initial condition, from index to depth [m].
268     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
269       (easier to get to a curvilinear grid) ; delX,delY no longer used.
270    o pkg/ggl90: a few modifications:
271     - fix bottom boundary condition, and interpolation of KappaE
272       near top and bottom
273     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
274     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
275     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
276    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
277      (maintain temporary backward compatibility, until next checkpoint)
278    
279    checkpoint61h
280    o pkg/diagnostics with "periodic averaging diagnostics":
281      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
282    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
283    o pkg/obcs: fix loop ranges for balancing code
284    o pkg/flt:
285     - improve criteria for finding which tile owns a float.
286     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
287    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
288      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
289      with ocean biogeo)
290    o pkg/flt:
291     - do some cleaning and fix the restart ;
292     - add output.txt in flt_example/results to get this pkg tested.
293    o genmake2: add an EXTENDED_SRC option and flag.
294       for now, cannot be turned on on command line (only through genmake_local)
295    o pkg/mdsio: read/write vector:
296     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
297     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
298       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
299     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
300      (drop to 4 digits matching for grad). But this test does not look very
301      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
302    
303    checkpoint61g
304    o pkg/flt:
305      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
306       + make OPTIONS file more standard.
307      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
308      - fix _BYTESWAPIO CPP-Flag
309      - standard reading of file-parameter "data.flt"
310      - fix argument list of S/R FLT_RESTART
311      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
312    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
313    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
314      a still unfixed compiler/optimization bug
315    
316    checkpoint61f
317    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
318      update results of global_ocean.cs32x15.icedyn test.
319    o move getcon.F from model/src to pkg/fizhi.
320    o pkg/exf: add parameter for extrapolation of temp up to the surface
321       and option to prevent negative evap (in bulk_largeyeager04 only).
322    o Prather Advection scheme: fix tracer conservation for divergent flow
323      (e.g., when using NonLin Free-Surface).
324    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
325    o gmredi (Visbeck-variable-K):
326     - add more parameters to Visbeck-variable-K.
327     - use a 5 points average for dSigmaR in Visbeck-K calculation
328       (more "homogenous": same stencil and same weights as in dSigmaH)
329     - update output of ideal_2D_oce experiment.
330    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
331      (#undef REAL4_IS_SLOW)
332     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
333       coordinate variable
334     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
335       (surface forcing fields), removes some of the functionality
336     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
337     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
338       probably not all: copy _RS surface flux fields to RL field before
339       calling DIAGNOSTICS_FILL
340     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
341       real*4 (CALL EXCH_*_RS) versions.
342     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
343       (generate new output).
344    
345    checkpoint61e
346    o gmredi (Visbeck-variable-K):
347      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
348      - change computation of Visbeck-K where Slope > Smax :        
349        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
350        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
351    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
352      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
353    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
354    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
355      does not become too large (to avoid precision problems in implicit-diffusion
356      solver); update ideal_2D_oce output.
357    o pkg ggl90:
358      - in ggl90_cal.F: compute only one set of visc/diff, used to
359        step forward TKE/T/S/momentum
360      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
361        have Prandlt =1)
362    o gmredi (fm07):
363      - add lower limit on Transition layer thickness + lower limit on 1/lambda
364      - allow to set few more params from data.gmredi
365    o pkg ggl90:
366          - add missing sqrt(2) factor in computation of mixing length
367            scale in ggl90_calc.F
368            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
369    
370    checkpoint61d
371    o adjoint modifs
372      - adapt to new field rhoInSitu
373      - allow to revert from StoreDynVars2D, StoreDynVars3D
374        to individual fields
375        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
376    o store 3-D (in-situ) density in commom block (DYNVARS.h)
377     - save 1 rho computation.
378     - no longer modify T & S inland when using down_slope pkg.
379    o gad_som : allow to switch to SOM advection for T & S without corresponding
380      pickup files (using new S/R: MDS_CHECK4FILE).
381    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
382      (for useSingleCpuIO to work in multi-threaded)
383    o pkg/shelfice:
384     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
385       with SHELFICEtopoFile in data.shelfice
386     - move code for reading ice shelf topography and modifying hFacC into separate
387       subroutines of the shelfice package
388     - separate initialisation of "fixed" and "variable" variables
389     - kTopC is not (yet) replaced by kSurfC, although this is possible
390    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
391    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
392      and rename:
393      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
394      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
395    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
396    
397    checkpoint61c
398    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
399      to add mass source/sink of fluid in the interior (3-D generalisation
400      of oceanic real-fresh water flux).
401    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
402    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
403    o new pkg: down_slope
404      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
405      - presently, modify T & S inland (dwnslp_calc_rho.F).
406        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
407      - implementation for ocean in P-coords not tested.
408      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
409    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
410      (to facilitate conversion of oceanic pkg to p-coordinate).
411    o change FIND_RHO to FIND_RHO_2D :
412      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
413    o new pkg: cheapaml
414    
415    checkpoint61b
416    o exch2:
417      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
418      - no longer depend on the order sequence (N,S,E,W).
419      - 3rd exchange no longer needed (tested with 24 tiles).
420      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
421      - exch_UV_A-grid readily available (but not yet tested).
422      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
423      (both are no longer needed) in exch_uv: no effect in forward run; but
424       get truncation error differences with adjoint exch.
425    o exch2:
426     - change index-bounds storage (moved from target to local tile,
427       more intuitive this way) ; rename/remove some variables.
428     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
429    
430    checkpoint61a
431    o exch2/matlab-topology-generator:
432      fix bug in index bounds for N-S internal exchange (hard to tell if this
433      had any effect on the solution).
434    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
435      is exceeded
436    o testreport: modify syntax of awk, so that it works also with
437      awk, and not only with nawk and gawk
438    
439    checkpoint61
440    o autodiff
441      Change default for TAF usage by removing argument '-nonew_arg'
442      This changes TAF subroutine argument list (ordering of active var.)
443      Omission of this flag leads to incompatibility w.r.t. TAMC
444      To restore TAMC-compatibility, need following modifs:
445      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
446      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
447      Tested TAF version is 1.9.22
448      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
449    
450    checkpoint60
451    --->>> This is the last checkpoint for which generating the adjoint
452    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
453    --->>> by default.
454    --->>> Future checkpoints will ommit this flag by default.
455    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
456    o pkg/grdchk: Add gradient check to etan0 perturbations.
457    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
458    o pkg/autodiff: more flexibility in zeroadj.
459      model/src: modifying do_oceanic_phys.F accordingly.
460    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
461    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
462      special setup of gmredi for which the adjoint is stable
463      enough for parameter optimization.
464    o bridging the gap between eddy stress and GM.
465      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
466          along with a change in CPP option (now ALLOW_EDDYPSI).
467      -> when using GM w/ GM_AdvForm:
468          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
469          is applied either in the tracer Eq. or in momentum Eq.
470          depending on data.gmredi (intro. GM_InMomAsStress).
471      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
472      The key modifications are in model/src/taueddy_external_forcing.F
473      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
474    
475    checkpoint59r
476    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
477      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
478      fix option to read coriolis(@ cell-corner) from files with CS-grid.
479    o pkg/mnc: add some attributes to standard 1D-coordinate variables
480    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
481      mass points, when using mnc for output
482      - add runtime parameter (missing_value, missing_value_int) to override
483        default (which is the value of getcon('UNDEF'))
484    o pkg/mnc: prepare mnc for the actual use of missing values with the
485      diagnostics package: small fix in mnc_cw_readwrite.template and more
486      initialisation of never used fields
487      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
488      versions
489    o pkg/thsice/thsice_ini_vars.F added default initial values so that
490      thermodynamics sea ice solver does not blow up when some initial fields
491      are missing.
492    o move from external_forcing_surf.F to ini_forcing.F
493      the p-coord. hack consisting in using pLoad to set phi0surf ;
494      update output of tutorial_global_oce_in_p (affected @ truncation level).
495    o Freshen up a bit hs94.1x64x5, notably:
496      remove rotationPeriod and tRef=5*0. (adjoint only), and add
497      exactConserv=.TRUE.
498    o pkg/generic_advdiff:
499      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
500      applies to files where Temperature & Salinity 2nd Order moments are used.
501    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
502      this uses a dynamically allocated internal state data structure
503      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
504      and requires a fortran 90 compiler
505    
506    checkpoint59q
507    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
508       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
509    o Refresh tutorial_global_oce_biogeo, notably:
510      - change bathymetry (put back seamounts in ACC, use hFacs)
511      - change EOS (POLY3 --> JMD95Z)
512      - use Bryan-Lewis vertical diffusivity
513      - use multidimensional advection
514      - remove old virtual virtual in dic pkg, now done through ptracer pkg
515      - change a couple of parameters in dic pkg
516    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
517    o pkg/obcs: change default to OBCSfixTopo = .true.,
518      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
519      - replace "debugMode" with "debugLevel .GE. debLevB"
520    o implementation of TAF directives for gchem,cfc,dic
521    o remove "exp5" (replaced by tutorial_deep_convection).
522    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
523      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
524      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
525      --> changes results in exp4, seaice_obcs
526    o tutorial_deep_convection :
527      update the set-up and increase resolution and domain size ; start
528      from pseudo initial conditions = output at t=120mn in order to see
529      something happening when running testreport.
530    o pkg/seaice: add os7mp as an advection scheme
531                  add check for advection schemes
532                  add a flag for restoring T and S underneath sea ice
533    o pkg/my82: add netcdf-support and diagnostics
534    o thsice pkg:
535      - Now hsMax limits snow height by turning it into ice following
536        flooding scheme (and now conserving energy)
537      - Slight rewriting of the formula in thsice_calc_thick.F
538      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
539      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
540    
541    checkpoint59p
542    o gchem / dic / cfc :
543      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
544      - add new parameter files: "data.dic" & "data.cfc" ;
545      - various re-arrangement in initialisation & header file ;
546      - fix tutorial_global_oce_biogeo for multi-threaded test.
547    o pkg/dic: test for "pickup_dic" file when restarting ;
548      if no pickup-file, can restart with a re-initialised pH (same as it did
549      before) providing pickupStrictlyMatch is set to False.
550    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
551      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
552    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
553      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
554    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
555     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
556       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
557    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
558       scheme to use for vorticty-term ;
559     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
560       (with default selectVortScheme, return to original discretisation)
561     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
562    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
563    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
564      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
565      also fix diagnostics VISCAHW & VISCA4W.
566    
567    checkpoint59o
568    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
569    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
570      move a few statemens out the main loop into separate loops
571    o pkg/shelfice:
572      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
573        (kg/m^2/s), does not break tests, because in verification/isomip,
574        rhoConstFresh=rhoConst (by accident)
575      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
576      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
577        new file model/src/seawater.F, so that they are available for all pkgs.
578      - convert potential temperature into in-situ temperature. This changes the
579        isomip tests => update tests
580    o add a flag writePickupAtEnd (default=true) to be able to suppress
581      writing a pickup at the last timestep
582    o tools/mpack-1.6 :
583      - disable automake (not working) and autoconf (not needed).
584      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
585        also cleaner with much less compilation warnings.
586    o pkg/profiles:
587      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
588      (for "less than 32 characters name" compiler requirement)
589    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
590      conditions that have a different sampling frequency than S/T/U/V obcs
591    o pkg/diagnostics (stats-diags):
592      - fix global Min/Max in case 1 processor get only empty tiles
593    o genmake2: replace (4 times)
594         make genmake_tc_1.o >> genmake_warnings 2>&1
595      with
596         COMM="$CC $CFLAGS -c genmake_tc_1.c"
597         echo $COMM >> genmake_warnings
598         $COMM >> genmake_warnings 2>&1
599      to make genmake2 always see the value of CC as specified in the optfile.
600    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
601      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
602      - modify verification advect_cs test to test SOM-advection on CS-grid.
603    o pkg/ctrl:
604      - Rewrite of ctrl_map_ini_ecco.F,
605        introducing a generic routine (ctrl_map_ini_gen.F).
606      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
607    
608    checkpoint59n
609    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
610      number in dedicate array "hdiag":
611      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
612        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
613      - many small changes (integer format) for large number of diagnostics
614      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
615        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
616    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
617      usingSphericalGrid, this allows to define the rotated grid coordinates
618      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
619      geographical coordinates according to the inverse of the rotation defined
620      by the Euler angles, so that Coriolis parameter and online-interpolation by
621      exf works with the geographical coordinates on XC/YC/XG/YG.
622      Naturally, this feature does not work with all packages, so some
623      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
624      profiles), because there the coordinates are assumed to be regular
625      spherical grid coordinates.
626    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
627      - introduce isopycnal diffusion coefficient control.
628    o tools/adjoint_options:
629      - additional control vector components.
630    o pkg/mnc: have mnc create marginally meaning full coordinate variables
631      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
632    o pkg/mypackage:
633      - add example of read/write pickup for state-var ;
634      - add entry points to the main code for state-vars diags & write-pickup.
635    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
636      transitions for useExfYearlyFields
637      - add new subroutine that determines the file to read from for
638        use*YearlyFields = .TRUE. and .FALSE.
639      - add a verification experiment to global_with_exf that tests
640        useExfYearlyFields with USE_EXF_INTERPOLATION defined
641    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
642      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
643      subroutines (which could be generated from a template, because they are
644      almost identical), for now they are included in obcs_prescribe_read.F for
645      simplicity
646    o pkg/exf:
647      - add a little more diagnostic to exf_interp_read (in analogy to
648        mds_read_field, can be turned off with debugLevel < debugLevA=1)
649      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
650        ugly but fast by unrolling short inner loops, inserting a unroll=8
651        directive in routine lagran, and splitting a loop and making do while the
652        outermost loop (the latter requires the intoduction of index arrays)
653    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
654    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
655      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
656    o verification/seaice_obcs: updated for restart test and latest options
657    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
658      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
659      for now this is only available for the C-grid code and also within
660      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
661    
662    checkpoint59m
663    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
664      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
665    o gad_som : fix flux output (& diagnostics) to have same units as other  
666      advection scheme fluxes (was previously multiplied by deltaT).  
667    o added verification/seaice_obcs both to test seaice open boundaries
668      and to provide an example matlab scrpt for generating them
669    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
670    o pkg/salt_plume: clean up salt_plume_frac.F to
671      remove redundancy in PlumeMethod 1 and 4
672    o pkg/kpp: added saltplume diagnostics
673    o pkg/obcs and pkg/seaice:
674      - do not set uice and vice to zero when OB*icefile are unspecified
675      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
676      - moved seaice tracer obcs after call to seaice_growth
677    o pkg/salt_plume: added various options for salt plume depth
678      criterion and for vertical distribution of the salt
679    
680    checkpoint59l
681    o pkg/ptracers: new version of ptracers pickup:
682      read meta file and write only fields which are needed to restart.
683      ( same logic as main pickup file ; also using pickupStrictlyMatch )
684    o pkg/seaice:
685      - add timescale for melting due to warm mixed layer as a means of
686        setting SEAICE_availHeatFrac more conveniently
687      - add a CPP-flag/runtime parameter check for flooding algorithm
688      - reformulated availHeat in seaice_growth.F to be independent of AREA
689    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
690      unit changes
691    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
692    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
693      SX vector computer.
694    o pkg/seaice:
695      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
696        seaice forcing fields can now be read only through pkg/exf
697      - removed some unused halos
698    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
699    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
700      or U/VICE from U/VWIND before computing U/VSTRESS
701    
702    checkpoint59k
703    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
704      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
705    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
706      all experiments pass when compile with un-initialised var. checking option.
707    o added pkg/salt_plume
708    o script to test restart (for now, in MITgcm_contrib/jmc_script)
709    o pkg/seaice: new read/write pickup version.
710      read meta file and write only fields which are needed to restart.
711      ( same logic as main pickup file ; also using pickupStrictlyMatch )
712    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
713    o lab_sea.hb87: modify the domain & update output.hb87.txt :
714      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
715      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
716      process. Fixed here by closing the domain at the Northern boundary.
717    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
718    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
719      a set of consecutive levels in/from a 3-D array.
720    o pkg/ptracers:
721      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
722      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
723    
724    checkpoint59j
725    o in pkgs: dic, obcs, offline, rbcs:
726      standard way to compute coeff. for time interpolation between 2 time reccords
727      which retains full precision (& make results less dependent on compiler).
728      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
729    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
730      packages instead of reading ice cover and wind speed separately
731    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
732     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
733      to allow to compile customized code before the update)
734    o cleaning-up:
735      - fix CPP instruction syntax in pkg/obcs
736      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
737        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
738      - fix some threads issue in IO parts.
739    o pkg/dic:
740      - add tons of "_d 0" (--> much better testreports !)
741       and then update outputs of tutorial_global_oce_biogeo
742    o pkg/mom_fluxform:
743      add a special version of momentum advection intended to conserve momentum
744      next to a bathymetry step or a coastline edge. (default = off = #undef)
745    o new read/write pickup version:
746      - for now, only implemented for main (mdsio) pickup file.
747      - write out only what is needed to restart; merge pickup_nh , pickup_ph
748        and main pickup together.
749      - read meta file; read only what is needed to restart; stop if a field
750        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
751        if it make sense (even if the restart is not perfect).
752      - if no meta file, assume that pickup to read corresponds exactly to
753        a pickup that would currently be written.
754      - read pickup written in the old format (until checkpoint59i) if it
755        recognizes an old meta file (no field-list).
756      - add a meta file in exp. which starts from a pickup: 2 cases:
757        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
758         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
759        b) a meta file describing the content of the associated pickup file
760         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
761    o pkg/mdsio & pkg/rw:
762      - new routine to read a meta file ; new set of routine to read
763        Multiple-fields file (with meta file).
764    o added open boundary conditions capability for seaice
765        HSNOW, HSALT, UICE, and VICE
766    
767    checkpoint59i
768    o adjoint:
769      * fix multiDimAdvection adjoint
770        (partial recomputation problem by TAF for fVerT(:,:,kDown)
771        and comlev1 size definition (maxpass vs. max. number of tracers)
772      * verification/global_ocean.90x45x15 adjoint now tests
773        NLFS and multiDimAdvection using DST3 (=30)
774      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
775    o pkg/kpp: add "_d 0" to real constant (if missing);
776      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
777      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
778    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
779      for internal parameters related to restart process (formerly from PARAMS.h)
780      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
781    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
782      as argument. (only atm2d & obcs write_pickup have not yet been updated)
783    o pkg/monitor:
784      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
785      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
786      - account for deep Atmosphere factor and density factor (anelastic)
787    o added open boundary conditions capability for seaice HEFF and AREA
788    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
789      thermodynamics
790      - requires a little reorganization, which affects the testreport results
791        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
792        so that now the conservative form is tested
793      - add a few comments
794    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
795    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
796    o add new diagnostics to seaice: advective, diffusive fluxes (only for
797      multidim-advection, for scheme 2 they are not filled) and transports,
798      thermodynamic growth rates
799    o change units of EmPmR (inside the code, + within coupling interface)
800      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
801      Affects results @ truncation level (cg2d match) and update output of
802       experiments: lab_sea(6), global_ocean.90x40x15(10),
803      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
804      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
805      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
806      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
807    
808    checkpoint59h
809    o pkg/exf:
810      - improve vectorization by moving if-statement out of loops in
811        exf_mapfields, exf_radiation
812      - exf_bulkformulae.F: introduce 2D fields and vectorize code
813    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
814    o testreport:
815      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
816        monitor & update offline_exf_seaice exp. output.
817      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
818    o pkg/seaice:
819      - bug fix in the evp solver: boundary conditions were affected be
820        masking of zMax/zMin (changes results)
821      - minor bug fix in boundary conditions in seaice_calc_strainrates
822        (changes results for no_slip)
823      - seaice_lsr.F: make interpolation of eta dependent on boundaries
824      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
825      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
826        stress formulation and no-slip boundary conditions
827    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
828      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
829    o pkg/seaice: a first HSALT time stepping equation has been checked in
830    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
831      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
832      without requiring DO-IF statements
833    o pkg/thsice:
834      use continuous power-law function for partition of energy between lateral
835      melting/freezing and thinning/thickening ; old code using step function
836      still available with #undef THSICE_FRACEN_POWERLAW
837      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
838    o testreport: change AD testing : check against results/output_adm.txt
839      using same scripts as for forward test.
840    
841    checkpoint59g
842    o adjoint testing: in preparation for changing testreport:
843      - output format: cost and grad written on separated lines
844      - ad output results in directory "results" (instead of "results_ad")
845    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
846    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
847    o pkg/ecco: allow user defined cost function contributions
848    o testreport:
849      Allow to choose (per experiment) the list of tested output variables
850       and the main variable (used to issue a pass/FAIL ) ;
851      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
852      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
853      Also modify printing of summary:
854       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
855       b) echo the list of tested variables in the individual summary.txt of
856          each experiment.
857    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
858      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
859      (but still depend on the tile decompostion of the domain).
860    o pkg/seaice: change a discretization detail to make the B-grid code
861      "more symmetric". This change is likely to remove all "ridges/leads" that
862      where quasi-aligned with the grid in B-grid solutions. It may also be
863      the solution to the stress coupling issues with the B-grid.
864    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
865      remove .cvsignore from input dir. (since testreport no longer run here).
866    o pkg/thsice:
867     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
868     - fix reshaping of sea-ice just after advection:
869       melt all the ice only if ice-volume is too small.
870     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
871       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
872     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
873    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
874      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
875    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
876      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
877      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
878      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
879      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
880      -> update output.txt
881    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
882     this affects truncation error: -> update output.txt of exp:
883      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
884      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
885    
886    checkpoint59f
887    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
888    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
889      a bounded range (in forward mode)
890    o pkg/ecco, ctrl, autodiff and mom_common:
891     internal parameter controls, completements of implementations
892    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
893    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
894      (not seem any difference in testing results).
895    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
896       at face corners.
897    o pkg/generic_advdiff:
898     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
899      loop range indices for computing vertical advection tendency
900      and do the calculation in the interior only (no overlap) ;
901      for now, only implemented for SOM advection (to save CPU time).
902     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
903    o exch2 adjoint
904      First set of changes:
905      - add exch2 hand-written adjoint templates
906      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
907        This will require cleanup in pkg/autodiff/*.F
908        (changed routines currently kept separate in verif. code/)
909      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
910        that used to hide exch2 or cubed-sphere specific code
911        (commented via 'cph-exch2')
912    o pkg/seaice
913      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
914    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
915       output of global_ocean.cs32x15.thsice .
916    
917    checkpoint59e
918    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
919      for B-grid vector (not yet tested) and C-grid vector (<- only used
920      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
921    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
922      (#ifdef ALLOW_SALT_PLUME)
923    o gather_2d/scatter_2d: removed halo regions
924    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
925      scheme and the corresponding test case (under front_relax dir). For now,
926      only available with Skew-flux form and not yet tested in realistic set-up.
927      adjoint: store directives updated, but gradient checks deteriorated,
928      so maybe GM/Redi adjoint is now broken.
929    o seaice adjoint
930      * add AREA, HEFF, HSNOW as control variable
931        (should not change lab_sea results)
932      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
933    o pkg/seaice:
934      * added computation of saltFlux in seaice_growth;
935        For time being, sea ice salinity is assumed constant
936        contribution of snow flooding to freshening of sea ice is neglected.
937        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
938        defaults to 0.0 in order to maintain backward compatibility.
939        Typical values for SEAICE_salinity are 4 to 10 g/kg.
940      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
941      * added SEAICE_availHeatFrac, which specifies fraction of surface level
942        heat content used to melt or grow ice
943      * commented out cap of HICE: it helps keep ice thinner
944      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
945      * applied OBCS T/S mask to HEFFM sea ice mask
946    
947    checkpoint59d
948    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
949     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
950     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
951    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
952     and change default value of parameter "GM_Small_Number";
953     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
954       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
955       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
956    o pkg/ecco: cost function when applying pkg/smooth to controls
957    o pkg/ctrl: add forcingPrecond run time parameter
958    o pkg/seaice:
959     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
960     - fix bug in metric terms of u-equation in LSR solver (implicit part),
961       changes verification/lab_sea
962     - rearrange implicit part of u-equation in LSR solver to make it easier to
963       read, understand, and debug. This causes changes at the truncation level.
964     - fix (serious) bug in the boundary conditions (sign error in the implicit
965       part) of the LSR solver. Changes all LSR results.
966     - fixed problem with HSNOW initialization to avoid thick snow when AREA
967       is initilized with small values - does not change lab_sea results.
968     - added HsnowFile initialization capability
969    o pkg/smooth: addition to model/src and pkg/ctrl so allow
970     initialization of pkg/smooth and application to control vector
971    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
972    o dependencies: pkg/profiles requires pkg/cal
973    o pkg/profiles:
974     - added option ALLOW_PROFILES_GENERICGRID
975         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
976         that interpolation information (grid points and coefficients) is provided
977         within the netcdf input files.
978         -> sample matlab scripts can be found in MITgcm_contrib/gael
979         that allow you to prepare netcdf input files.
980     - also modified: cleaner include statements, cleaner error print statements,
981       cleaner stops when error, and more tests of the netcdf input files consistency.
982    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
983    o pkg/seaice:
984     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
985       requires a new routine: seaice_diagnostics_fill.F
986     - make sure that seaice does not move if not forced (pressure replacement
987       method, Hibler and Ip, 1995), changes results
988     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
989     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
990       It is turned off by default (=-1.), because it changes the results.
991     - make it possible to read AREA from a file, too.
992    
993    checkpoint59c
994    o add S/R and diagnostics for oceanic mixed-layer depth
995    o move GMRedi call after all vertical mixing schemes (including KPP)
996    o pkg/thsice:
997     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
998      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
999    o pkg/obcs:
1000     - bug fix for balance code
1001    o pkg/seaice:
1002      - allow values of SEAICE_elasticParm > 1
1003      - add new parameter SEAICE_evpTauRelax as an alternative
1004        to SEAICE_elasticParm
1005      - make lsr boundary conditions free slip (by default), changes result
1006      - add code for no slip boundary conditions for lsr
1007      - set minimum of zeta to zero (and not 4e8) (changes results)
1008      - add a cap on AREA after advecting AREA if seaice_growth is not called
1009    o change calculation of Visbeck K:
1010      - no longer depend on tapering scheme; instead, compute slope (limited
1011        by GM_maxSlope). this is equivalent to what was comuted before with
1012        clipping or linear tappering.
1013      - fix vertical averaging (wrong by 1/2 level)
1014      - leave the old version (but will not be maintained) within
1015        #ifdef OLD_VISBECK_CALC / #endif
1016      - update output of exp. ideal_2D_oce
1017    o change error catch in calc_r_star to improve vectorization
1018    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1019      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1020    o adjoint:
1021      Re-organized adjoint checkpointing according to Matt Mazloff
1022      (but with modifs/completions/cleanups)
1023      Storing is now bundled into large arrays to optimized I/O
1024      (and second step in cleanup of the_main_loop)
1025    
1026    checkpoint59b
1027    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1028      - export/import (between ocean & coupler) fields needed for ocean DIC.
1029    o pkg/seaice:
1030      - get rid of three more exchanges seaice_calc_viscosities (required
1031        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1032      - bug fix in seaice_ocean_stress (update of lab_sea required)
1033      - reduce loop boundaries to necessary minimum also in seaice_evp
1034      - go back to the old way of computing deltaC/Z as the adjoint likes that
1035        better
1036    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1037      passive tracer to an Age Tracer) + update output.txt
1038    o pkg/exf:
1039      - implement A-grid / C-grid selection for wind-stress input files.
1040      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1041      for now, in exf_bulk_largeyeager04.F only :
1042      - change implementation for case where windspeed + 2. components wind-stress
1043        are read-in. AND use rhoConstFresh to convert evap.
1044    o pkg/seaice:
1045      - use correct EXCH_UV for wind-forcing (on A-grid).
1046      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1047        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1048    o pkg/exf:
1049      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1050      EXF_INTERPOLATION:
1051      - merge global_with_exf/code version of exf_interp_read.F
1052        to the main code ;
1053      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1054        reading the file ; Important: This options needs to be defined to recover
1055        previous code.
1056        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1057      - no longer loose real*8 precision along the way when using exf_iprec=64.
1058    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1059      - change discretisation of evp-solver in order to avoid another exchange
1060        (changes lab_sea) and clean up a little
1061      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1062        help the adjoint (this also changes the results slightly)
1063      - add a few "_d 0" where they had been missing in seaice_evp.F
1064      - cleaning up: remove unused seaice_calc_rhs.F
1065    o pkg/exf: some cleaning-up:
1066      - change various "constants" into runtime parameters
1067      - cleaned-up Large&Yeager04 routine which should eventually
1068        replace exf_bulkformulae.F (changed names of S/R and CPP)
1069        and merged various ALLOW_ATM_WIND options
1070     only used with thsice pkg (in thsice_get_exf.F):
1071      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1072        which are used when useStabilityFct_overIce=TRUE (= the default)
1073      - change default values of ice & snow emissivity and scale downward LW
1074        by ice & snow emissivity.
1075    o pkg/thsice:
1076     fix few little problems, in thsice_calc_thickn.F:
1077      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1078      - melt only laterally if hIce < hThinIce (as the comments say)
1079      and in thsice_extend.F:
1080      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1081      - start to form ice as soon as the minimum ice-volume is reachable.
1082     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1083      and cpl_aim+ocn
1084    o pkg/kpp
1085     - move computation of surface related input fields to KPP into a new
1086       subroutine kpp_forcing_surf.F
1087     - remove wrong (within bi,bj loops) EXCH calls.
1088     - little cleaning (add argument myThid in last position, cvs header ...)
1089     - for now, fix conservation problem by exchanging KPPviscAz (may not
1090       be the best fix)
1091    o pkg/seaice
1092     - check for inconsistent evp parameter/cpp-flag combination
1093     - remove leftover errIO flat for obsolete name list error handling
1094    o OpenAD
1095     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1096    
1097    checkpoint59a
1098    o pkg/seaice: some parameter clarifications and a little bit of clean up
1099    o pkg/thsice: rename run-time parameters:
1100       himin       -> hIceMin
1101       himin0      -> hThinIce
1102       hihig       -> hThickIce
1103       i0          -> i0swFrac
1104       transCoef   -> bMeltCoef
1105       frac_energy -> fracMelting
1106      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1107       with default values (for now) that do not change the results.
1108      remove old version of thsice vars advection in pkg/seaice.
1109    o in FFIELDS.h:
1110      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1111      - make pLoad & sIceLoad always available (but still only used if
1112         ATMOSPHERIC_LOADING is #define).
1113    o pkg/kpp: replaced _KPP_RL with _RL
1114    o bug fixes for vertical diffusivity computations when both KPP and
1115        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1116        are no longer updating the vertical diffusivity array
1117        (passed as argument) but are (re-) setting those arrays.
1118    o pkg/seaice: fix bug in evp solver, while doing that
1119      - change (improve?) discretization of stress computations for both
1120        cgrid-lsr and evp solver
1121      - add a new routine to compute strain rates
1122      - the above changes lab_sea results
1123      - add no slip conditions for evp solver (off by default), lsr-version
1124        may follow
1125      - fix exchange for shear at Z-points (does not change lab_sea)
1126      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1127        (to force the user to pick a time step since there is not "safe" way
1128        of choosing it)
1129      - add principal stress diagnostics
1130      - rearrange fields for evp a little to avoid having to call a: too many
1131        exchanges and b: exchanges for stress trensor components which we do
1132        not have.
1133      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1134        of evp, complete rewrite for lsr case (latter is does not yet work
1135        in all cases)
1136    o pkg/kpp: add code to have mixing in shelf ice caverns
1137      - add myThid to all kpp routines (long overdue)
1138    
1139    checkpoint59
1140    o pkg/exf:
1141      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1142        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1143      - move exf header files from lower_case.h to UPPER_CASE.h ;
1144        add missing cvs Header & Name
1145      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1146      - add namelist param. selectStressGridPosition, exf_monFreq
1147      - retire many _CLIM routines, and remove data.exf_clim
1148        + params moved to data.exf
1149        + climsst, climsss now handled by exf_set_gen, i.e.
1150          climss?period=0 refers to constant field,
1151          climss?period=-12 to monthly forcing
1152      - split up namelists in data.exf
1153    o pkg/seaice:
1154      - remove seaice_exch and seaice_exch_uv
1155      - remove superfluous exchange of theta
1156      - add myThid to seaice_budget_ocean/ice
1157      - add new interface for atmospheric wind forcing (C-grid only)
1158        + new routine
1159        + two new field (taux, tauy for stress over ice)
1160        + removed one global field (DAIRN) for C-grid case only
1161    o pkg/thsise
1162      - 2nd set of modifs for thsice adjoint in conjunction with exf
1163    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1164    
1165    checkpoint58y_post
1166    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1167      vertical diffusivity, similar to that in MOM4; turned on using
1168      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1169      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1170    o Added capability for 3D specification of background vertical diffusion
1171      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1172      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1173      "data" file that contains the 3D vertical diffusivity coefficients.
1174    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1175      - add code within pkg thsice to advect & diffuse sea-ice fields
1176      similar to (and will replace) what has been added in  seaice_advdiff.F,
1177      but: - conserving Mass, Heat & Salt.
1178           - better when using non-linear advection scheme (not yet fully tested)
1179           - can also be used in atmospheric set-up (for now, only the diffusion).
1180    
1181    checkpoint58x_post
1182    o IO option for global-file compact format:
1183      - add options when generating topology (utils/exch2/matlab-topology-generator)
1184      - add I/O capability (pkg/mdsio).
1185      - adapt utils/matlab/rdmds.m to read this format.
1186      for now long-line format not yet supported by pkg/mdsio (& exch2).
1187    o shelfice: add a few diagnostics
1188    
1189    checkpoint58w_post
1190    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1191      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1192      (and replace horiVertRatio in NH code).
1193      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1194                         and tutorial_plume_on_slope (sensitive to truncation)
1195    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1196      directly to drive seaice model (C-grid only)
1197    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1198     - reintroduce computation of wind from stress,
1199     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1200       mass points to avoid tau = 0
1201     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1202    o rdmnc.m: make it work with "global" files created with gluemnc
1203    o rdmnc.m : some improvements in dealing with singleton dimension
1204      (tested on all testreport mnc output files).
1205    o genmake2: disable pkg/profiles if netcdf test fails.
1206    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1207    o move call to cal_readparms up to make calendar parameters/variable available
1208      to all packages
1209    
1210    checkpoint58v_post
1211    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1212      useDynP_inEos_Zc tested.
1213    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1214    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1215      and portions thereof.  See read_cs.txt for description and examples.
1216    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1217      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1218      following the great-circle arc between those 2 points.
1219    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1220      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1221    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1222     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1223     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1224     - still needs work (not working with some options ; efficiency to improve)
1225       and serious testing.
1226     - use this scheme for temperature & salinity in 2 advection test exp.:
1227       advect_xy & advect_xz, respectively.
1228    
1229    checkpoint58u_post
1230    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1231    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1232    o testreport: add option "-skipdir" to skip some test.
1233    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1234      momentum calculation.
1235    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1236    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1237      remove checkpoint.F and the_correction_step.F (no longer used);
1238      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1239    o add option (linFSConserveTr) to correct for tracer source/sink due to
1240      Linear Free surface
1241    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1242    o pkg/thsice: fix reading mnc-pickups
1243    
1244    checkpoint58t_post
1245    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1246    o pkg/mdsio:
1247     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1248       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1249       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1250     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1251     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1252       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1253     - new S/R (to replace MDSWRITEMETA), which allows to write more
1254       informations (variable names, time ...) to meta files.
1255     - modify rdmds.m to give back the meta file content.
1256    o pkg/diagnostics: change vertical interpolation to be safer, and more
1257       flexible (define p-levels to interpolate to in data.diagnostics);
1258      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1259       diagnostic pointer.
1260    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1261    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1262    o fix multi-category seaice:
1263     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1264       SEAICE_MULTICATEGORY
1265     - fix short wave heat flux
1266    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1267       and allow to use EVP solver. Change forward lab_sea: test both EVP
1268       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1269    o Initial check-in of lab_sea adjoint
1270      (very similar to natl_box_adjoint/code_seaice)
1271      * used C-grid and EVP solver
1272      * used KPP, GM/Redi
1273      * uses inAdExact=.TRUE.
1274      * gradient checks fail for both ADM and TLM
1275        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1276        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1277        issue is related to forward mismatch between g77 an ifort
1278    o pkg/seaice: overhaul of thermodynamics
1279     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1280     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1281     - move a few global fields out of SEAICE.h into seaice_growth.F and
1282       make them 2D (FICE/QNETO/ ...)
1283     - remove FO (it is the same as QNETO)
1284     - introduce a few local fields to avoid modifying external fields such
1285       as atemp, etc.
1286    
1287    checkpoint58s_post
1288    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1289      changed exf_set_gen.F so that
1290        genperiod=0 means input file is one time-constant field and
1291        genperiod=-12 means input file contains 12 monthly means
1292    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1293      this affects truncation error ; generate new output file for exp. which
1294      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1295        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1296        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1297        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1298        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1299        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1300    o start implementation of deep-atmosphere and anelastic formulation
1301    o verification: remove 2nd copy of input files and use script "prepare_run"
1302      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1303    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1304  o profiles: fix for multithreaded case  o profiles: fix for multithreaded case
