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