5      ==============================      ==============================
6    
7    checkpoint61y
8    o pkg/seaice
9     - change (once again) the discretization for the evp solver: rather than
10       squaring the averages of strain rates, average the squares to give
11       a better approximation to VP behavior (in simple test); this breaks
12       verification experiments that use EVP (lab_sea and lab_sea.hb87)
13        --> update outputs
14    o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit)
15      to improve vectorization of adjoint code on TARGET_NEC_SX
16    o verification/vermix:
17      - change vermix to a more "classical" 1d column with high vertical
18        resolution, seasonal heat flux forcing and constant wind forcing
19        --> update outputs
20    o pkg/seaice
21     - fix diagnostics of principal stress components for EVP
22     - add optional diagnostics of non-linear convergence for LSOR solver
23     - make maximum zeta a runtime parameter
24    o model/src (3-d solver):
25      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
26       which consisted in removing the Surf. Non-Hydrostatic pressure from the
27       whole column and adding it to Eta (inspired from Casualli, 1999):
28       Only affects 3-D solver initial guess and only if using ExactConserv,
29       but tests did show a degradation of solver convergence. For this reason,
30       decide to disable this piece of code.
31       to recover previous version, just set zeroPsNH = exactConserv (line 78).
32      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
33    o pkg/ggl90:
34     - fix previous modif (unfortunatly has not been documented here).
35    o pkg/seaice/autodiff:
36     - add CPP flag to include clipping of zeta in EVP code;
37       although clipping of zeta is not necessary for EVP and not recommended
38       it was done by default, now clipping is disabled by default
39     - modify computation and store zetaC/Z in seaice_evp for TAF
40     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
41     - change seaice_calc_viscosities/strainrates for better
42       vectorization after AD by TAF
43     - rearrange common blocks in SEAICE.h once again for easier dumps of
44       adjoint output, adjust adcommon.h and g_common.h
45     - change flux form of default advection scheme for better vectorization
46       of adjoint code
47     - modify lab_sea/input.lsr to test the flux form of default advection
48       scheme
49    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
50      transition in checkpoint61r)
51    
52    checkpoint61x
53    o adjoint: adding two new verification experiments
54      * tutorial_global_biogeo: an online dic sensitivity experiment
55        (work with G. Forget)
56      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
57        (an update of the Dutkiewicz et al., 2006 paper)
58      Both use the same CO2FLUX cost function, but different controls
59      Gradient checks look good, but some recomp. could still be traightened out
60      Should add xx_dic control variable to test at some point
61    o model/src:
62      add run-time parameters to check and/or mask initial Temp & Salt
63    o pkg/ptracers:
64      apply zonal filter (if used) to all passive tracers
65    
66    checkpoint61w
67    o adjoint:
68      * update and finish work on adjoint of dic package (G. Forget)
69      * start adjoint of offline package
70      * bug fix for cube-sphere TLM code (active_file_g.F)
71    o tutorial_global_oce_optim:
72      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
73      and add SIZE.h_mpi for MPI testing
74    o pkg autodiff
75     - fix bug in autodiff_restore
76     - make genmake2 remove comments and empty lines from ad_input_code.f in
77       order to reduce file size (new script file remove_comments_sed)
78    o allows to specify vertical profile of vertical viscosity (viscArNr)
79    o pkg autodiff
80      autodiff_ini_model_io: comment out writing of grid information to netcdf
81      files, because at this time the grid fields are a bunch of zeros
82      (this is analogous to ini_mnc_vars.F)
83    o pkg seaice/autodiff:
84     left-over from removing the 3-time-level fields:
85     - small rearrangement of common blocks (SEAICE.h)
86     - fix field declaration in order to get meaningful output in
87       adseaice.*.nc (adcommon.h)
88    o pkg obcs:
89     - go through NH code only if nonHydrostatic=T
90     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
91     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
92       => Update output of experiment seaice_obcs
93     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
94     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
95     - fix restart for useOBCSprescribe + useEXF
96    o pkg ctrl
97     - make obcs as control parameter work also with useSingleCPUio
98     - replace a few sny and snx by Ny and Nx to be consistent with
99       ctrl_set_globfld_x/yz.F
100    o pkg seaice
101     - re-introduce global field frWtrAtm for the case of
102       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
103     - catch the case of an empty filename in seaice_cost_init_fixed.F
104    o pkg ecco:
105     - small bug fixes in the_main_loop
106      . fix order of monitor arguments
107      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
108      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
109        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
110     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
111       imbalance diagnostics for wmean_h/sflux = 0
112     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
113     - catch the case of empty filenames in ecco_cost_init_fixed.F
114       and ecco_readparms.F
115     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
116       to make this statement meaningfull in ecco_cost_weights.F
117    o pkg zonal_filt:
118      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
119      - when using rStar, filter uVel*hFacW instead of uVel
120       (tested without topography: fix a Pb of growing instability with NLFS)
121    o pkg/aim/thsice:
122     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
123      (works as SST restoring)
124    o pkg/thsice:
125     -add specific parameter for salt restoring in slab mixed-layer
126       (by default equal to the temperature restoring)
127    
128    checkpoint61v
129    o pkg/kpp:
130     -add double diffusive contributions as a hack, turned off by default
131      for now, and the code can be excluded with a CPP-flag
132      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
133     -add a verification experiments to "vermix" to test this code
134    o pkg/mom_common:
135      Move computation of length scales to mom_init_fixed.F (avoid recomputation
136      at each time-steps*levels).
137    o pkg/layers:
138      Created a new package for computing volume fluxes in temperature or
139      [not yet implemented] density layers, e.g. for calculating residual
140      overturning circulations.
141    o pkg/diagnostics:
142      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
143    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
144    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
145      To avoid mixing type (RS/RL) of input/output array argument,
146      replace single mixed-type array with a pair from each type (RS/RL).
147    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
148      is now implemented for all pkgs (previously only done for the main pickup)
149    
150    checkpoint61u
151    o pkg/obcs:
152      - change OB?eta from _RS to _RL and put them into a separate commen block
153      - add code to read OB?eta from a file via obcs_prescribe_read: the code
154        compiles and does not destroy any other experiments, the data is read
155        properly, but the code is not tested in actual applications
156    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
157      create a meaningful unit attribute for the time coordinate variable
158    o pkg/ebm: add plenty of missing "_d 0" ;
159       update results of experiment global_ocean_ebm (fwd + adjoint tests)
160      Notes: several pieces of code only works for (very) specific set up
161       (domain size, lat range, etc ...); should be documented & stop if one
162       of those assumptions is not meet.
163    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
164       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
165          and offline_exf_seaice (seaicetd + adjoint).
166    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
167       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
168        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
169    o few changes to pass when compiling with strick checking of arguments
170       across S/R (allow to find few bugs in S/R calls).
171    o pkg/seaice:
172     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
173       2d-fields, for slightly better performance
174    
175    checkpoint61t
176    o pkg/seaice:
177     - remove unused variables in seaice_evp
178     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
179    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
180       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
181       each processor opens a different file (a fix from Matt).
182    o cg2d:
183       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
184       this reduces number of EXCH calls by 2 when using exch2.
185       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
186       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
187    o pkg/thsice:
188       add code for Near Infra-Red albedo (from Jeff)
189       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
190    o ini_model_io:
191       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
192       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
193       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
194    
195    checkpoint61s
196    o pkg/exch2 (exch2_rxN_cube*):
197       remove last BARRIER (no need to synchronise after getting data from shared
198       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
199    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
200      and generate new output (for the 2 tests) using default rotationPeriod.
201    o pkg/exch2:
202      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
203        (was already the case with AUTODIFF_EXCH2 defined)
204      - add bj in exch2 arrays and S/R.
205      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
206        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
207    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
208      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
209        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
210      - verification experiment natl_box.longstep
211    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
212      allow different versions of ifort (8 or 9) and different versions
213       of mpi (mpich or mpich2) to be used with the same optfile.
214      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
215       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
216    o pkg/seaice:
217      fix previous modif (3-level field removed) for old-pickup reading
218    
219    checkpoint61r
220    o pkg/seaice:
221     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
222      1. introduce fields for time step (N-1)
223      2. do not use levels 2 and 3 anymore (but keep them)
224      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
225         includes changes to pkg/thsice/thsice_get_velocity.F,
226         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
227         pkg/obcs/obcs_apply_uvice.F.
228     - completely remove code for leap-frog time stepping for second order
229       advection
230     - adjusted adjoint accordingly;
231       gradient checks have improved by an order of magnitude!
232    
233    checkpoint61q
234    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
235     - the boundary conditions along open boundaries are unclear, because the
236       associated masks are set to zero and are thus treated as closed when
237       applying the slip-boundary conditions.
238     - move initialisation of grid variables from seaice_init_varia to _fixed
239    o adding doc/diags_changes.txt
240    o model/src:
241      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
242       to avoid "_diags" naming if no relation to pkg/diagnostics.
243      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
244       file and only call PLOT_FIELD_XYZ if debugMode=T.
245      remove few PLOT_FIELD_XY calls outside initialisation.
246      remove few unnecessary BARRIER.
247    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
248      of salt_plume package in Southern Ocean
249    o pkg/thsice:
250     - fix hOceMxL in overlap (needed for sea-ice advection);
251       update output of experiment global_ocean.cs32x15.icedyn.
252    o pkg/seaice:
253     - make the (placeholder-)tracer IceAge a little more meaningful
254      by avoiding ridging of age due to convergent ice flow
255     - add diagnostics for surface temperature, atmospheric and oceanic
256       heat flux, and atmospheric and oceanic ice growth
257    
258    checkpoint61p
259    o eesupp (global_max & global_sum):
260     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
261     - remove starting & endding barrier (no longer needed)
262    o pkg/mdsio, writelocal:
263       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
264       (remove the STOP): uses shared buffer IO to store data from all threads
265       and then let master-thread write nThreads tiles.
266    o pkg/mdsio (read/write field):
267     - tiled IO done in 1 piece (all levels at a time);
268     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
269     - multi-threaded: allow to read/write local (non-shared) array
270       (was already working with singleCpuIO ; now works also without);
271       => no longer needs barrier call after reading a file (added inside
272       mds_read/write field).
273     - move barrier calls outside gather/scatter_2d to mds_read/write_field
274    o pkg/obcs/exf
275      - exf_getffieldrec.F: add a few ". _d 0" and
276                            add code to catch the case fldperiod = 0.  
277      - obcs_precribe_read.F: change if statements so that they match
278                              the variable type (_RL)
279      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
280        exf_iprec) as part of namelist EXF_NML_01
281    o pkg/mdsio:
282      - read/write tiled (local) files: read/write 1-level tile chunk at a time
283        (instead of segment of length sNx); expected to speed up tiled IO.
284    o pkg/exch2:
285      - take buffer copy from/to array out of S/R exch2_send/recv into new
286        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
287        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
288      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
289      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
290        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
291        including Topology header file (and common blocks).
292      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
293        remove 2nd exch call in exch2_s3d_rx (no longer needed).
294      - document S/R arg. list (+ update some comments)
295    o pkg/seaice:
296      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
297        temperature and humidity over sea ice based on climatological values.
298      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
299        of LSR (this change is expected to change the results slightly because now
300        it uses slightly difference moduli from the second last LSR solution, but
301        that is more consistent with the stress computations; this part of the code
302        is not tested in the verification experiments)
303      - fix diagnostics for flux of ice in case of B-grid
304      - turn strain rates eij and press into global fields within global
305        common block in SEAICE.h for more straighforward diagnostics
306      - fix diagnostics for principal stress components, press, zeta, eta
307        to give something meaning full
308    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
309      new output (all 4 tests) using default rotationPeriod.
310    o pkg KPP:
311      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
312      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
313        and normal grid from 1 to Nr)
314    o Fix computations of L4rdt in mom_calc_visc.F
315    o eesupp:
316      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
317      should be called before a "stop" if we know that all process are going
318      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
319    
320    checkpoint61o
321    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
322    o model/src/ini_curvilinear_grid.F:
323       compute angleSin/CosC when they are not read from a file
324    o pkg/seaice:
325       add pseudo time stepping for LSOR
326    o pkg/exch2:
327       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
328    o pkg/seaice:
329       Adding separate sea ice albedo, drag coefficients, and HO in Southern
330       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
331    o SingleCpuIO:
332       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
333    o pkg/seaice:
334       put exchanged variable in (local) common block for MPI+Multi-Threads
335       to work (necessary with exch1, and for now with exch2 too).
336    o verification: to get more experiments tested with mpi, mth and mpi+mth,
337      change tiling of:
338       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
339       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
340      update output of exp:
341       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
342       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
343      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
344                       (note: output.txt generated on faulks using only 1 tile)
345    o eesupp & mdsio (SingleCpuIO):
346     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
347       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
348       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
349     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
350     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
351       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
352    o pkg/exch2:
353     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
354       read parameter file "data.exch2" if it exists; otherwise try default regular
355       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
356     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
357       with new code (not to be used, just as a backup solution).
358     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
359       in utils/exch2/input.
360    
361    checkpoint61n
362    o eesupp & mdsio (SingleCpuIO):
363      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
364        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
365        receive real*4 array (instead of real*8) to read/write 32.bit files.
366        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
367         and remove new mapping S/R)
368    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
369      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
370        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
371        when using exch2. Add S/R to map global io-buffer to global model array.
372      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
373    
374    checkpoint61m
375    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
376      and add 3 other S/R for other types (R4,R8,RS).
377      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
378    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
379     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
380     - reduce number of macro definitions (keep only those which are used);
381       can always call directly the corrresponding S/R if needed.
382     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
383       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
384     Fixed wrong type of arg in:
385       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
386       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
387     To fix: global_sum of var in common block is wrong (multi-threaded) in:
388       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
389     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
390    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
391      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
392    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
393    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
394      edges are closed (zero depth); might happen with "blank tiles";
395      for now, disabled if using OBCS.
396    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
397      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
398    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
399      to reduce length of 1.D array print in STDOUT.
400    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
401      + use 48 tiles (16x8): this will allow to test "blank tiles".
402    o start to test MPI + multi-threaded (change testreport to skip tests
403      where number of tiles do not match).
404    o genmake2: add option "-omp" to turn on Open-MP ;
405      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
406    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
407      and keep the original tile numbering. Note: compatible with old
408      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
409    
410    checkpoint61l
411    o Overlaps had been forgotten in calculating ijk keys : fixed
412    o fix cyrus makedepend for gcc 4.4
413    o experiment fizhi-cs-aqualev20:
414      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
415      and generate new output. Note: new output is much closer to the old
416      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
417      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
418    o pkg/fizhi:
419     - change to avoid indices going deliberately over array-bounds
420     - remove unnecessary MPI stuff
421     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
422     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
423       does not go over array-bounds and therefore returns reliable output.
424     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
425       this S/R has 4 output arguments, which are used inside "get_alarm";
426       when it is called with the same variable "ndum" in place of several
427       output arguments, this produces weird side effect inside "get_alarm"
428      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
429       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
430       address) and produces error.
431    o tools/gemake2: (March 27-29 2009)
432      with option "-mpi": link *_mpi files from "MODS" dir (this is what
433      testreport does).
434    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
435    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
436       update lab_sea.lsr & lab_sea.salt_plume results
437    o pkg/seaice:
438      Major overhaul of the LSOR solver: change discretization from original
439      finite differences to finite volume. The old routine is still in the
440      file seaice_lsr.F and can be turned on with the CPP-flag
441      SEAICE_OLD_AND_BAD_DISCRETIZATION
442      Along with this change, the discretization of the strain rates is changed.
443      The same flag turns on the old discretization in seaice_calc_strainrates.F
444      All verification experiments with seaice are affected (except for
445      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
446      results by setting the above flag.
447      Further changes involve changes in defaults:
448      - ALLOW_FLOODING is defined and turned on by default
449      - SEAICEadvSnow = .true. is now the default
450      - SEAICEadvSalt = .true. is now the default
451      - SEAICEadvAge  = .true. is now the default
452      - SEAICE_clipVelocities  = .false. is now the default
453                                         (as per J. Zhang's recommendation)
454      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
455        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
456      - seaice_growth: replace computation of UG by a simple copy from wspeed
457    
458    checkpoint61k
459    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
460      seaice_lsr: fixed a few metric terms,
461                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
462                  add more debugging diagnostics
463      seaice_evp: removed superfluous many metric terms of FV discretization
464                  of stress divergence
465                  affects lab_sea, lab_sea.hb87
466      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
467                  of stress divergence for non-evp solver
468                  (this part is not tested anywhere)
469      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
470                  they were effectively only half slip
471                  affects lab_sea.hb87
472      updated all relevant verification experiments (except lab_sea//output_adm.txt
473        which was left over, but fails at level 7 & 6)
474    
475    checkpoint61j
476    o pkg/seaice: turn a few hard wired parameters into run time parameters
477    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
478      time in seconds as promised by the usints in seaice_monitor and exf_monitor
479    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
480      that are not cubed-sphere grids
481    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
482    o pkg/ctrl:
483      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
484    o non-hydrostatic (calc_gw.F):
485      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
486      update output of exp. global_ocean.cs32x15.viscA4
487    o remove backward compatibility for thetaMin,phiMin
488      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
489    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
490      interpolated wind field not only for curvilineargrid=.true., but also
491      for a rotated grid (rotateGrid=.true.)
492    o pkg/exf: add capability to bypass interpolation for runoff
493      by setting yet another CPP-flag
494    o eesupp/src, B-grid exchange:
495      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
496    o autodiff
497      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
498      allows to switch to single-prec common blocks;
499      corresponding switch occurs in tamc.h, integer isbyte
500      TAF store directivs "byte" and "kind" seem equivalent;
501      Most tamc.h have been updated correspondingly.
502    
503    checkpoint61i
504    o autodiff:
505      fix autodiff_sore/_restore indices for obcs
506      (spotted by I. Hoteit, M. Mazloff)
507    o pkg/autodiff, pkg/ctrl:
508      Add flag to reduce all tapelev I/O to single-prec.
509      In data.ctrl set
510        doSinglePrecTapelev = .TRUE.
511    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
512      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
513    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
514      real fresh water flux (not yet)
515    o pkg/mdsio & rw:
516     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
517     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
518    o pkg/flt:
519     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
520       init_fixed & ini_varia.
521     - clean-up & simplify linear interpolation S/R:
522       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
523     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
524     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
525     - add vert. coordinate & horiz. indices to output files.
526     - change vertical position in initial condition, from index to depth [m].
527     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
528       (easier to get to a curvilinear grid) ; delX,delY no longer used.
529    o pkg/ggl90: a few modifications:
530     - fix bottom boundary condition, and interpolation of KappaE
531       near top and bottom
532     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
533     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
534     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
535    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
536      (maintain temporary backward compatibility, until next checkpoint)
537    
538    checkpoint61h
539    o pkg/diagnostics with "periodic averaging diagnostics":
540      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
541    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
542    o pkg/obcs: fix loop ranges for balancing code
543    o pkg/flt:
544     - improve criteria for finding which tile owns a float.
545     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
546    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
547      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
548      with ocean biogeo)
549    o pkg/flt:
550     - do some cleaning and fix the restart ;
551     - add output.txt in flt_example/results to get this pkg tested.
552    o genmake2: add an EXTENDED_SRC option and flag.
553       for now, cannot be turned on on command line (only through genmake_local)
554    o pkg/mdsio: read/write vector:
555     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
556     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
557       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
558     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
559      (drop to 4 digits matching for grad). But this test does not look very
560      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
561    
562    checkpoint61g
563    o pkg/flt:
564      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
565       + make OPTIONS file more standard.
566      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
567      - fix _BYTESWAPIO CPP-Flag
568      - standard reading of file-parameter "data.flt"
569      - fix argument list of S/R FLT_RESTART
570      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
571    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
572    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
573      a still unfixed compiler/optimization bug
574    
575    checkpoint61f
576    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
577      update results of global_ocean.cs32x15.icedyn test.
578    o move getcon.F from model/src to pkg/fizhi.
579    o pkg/exf: add parameter for extrapolation of temp up to the surface
580       and option to prevent negative evap (in bulk_largeyeager04 only).
581    o Prather Advection scheme: fix tracer conservation for divergent flow
582      (e.g., when using NonLin Free-Surface).
583    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
584    o gmredi (Visbeck-variable-K):
585     - add more parameters to Visbeck-variable-K.
586     - use a 5 points average for dSigmaR in Visbeck-K calculation
587       (more "homogenous": same stencil and same weights as in dSigmaH)
588     - update output of ideal_2D_oce experiment.
589    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
590      (#undef REAL4_IS_SLOW)
591     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
592       coordinate variable
593     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
594       (surface forcing fields), removes some of the functionality
595     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
596     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
597       probably not all: copy _RS surface flux fields to RL field before
598       calling DIAGNOSTICS_FILL
599     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
600       real*4 (CALL EXCH_*_RS) versions.
601     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
602       (generate new output).
603    
604    checkpoint61e
605    o gmredi (Visbeck-variable-K):
606      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
607      - change computation of Visbeck-K where Slope > Smax :        
608        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
609        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
610    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
611      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
612    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
613    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
614      does not become too large (to avoid precision problems in implicit-diffusion
615      solver); update ideal_2D_oce output.
616    o pkg ggl90:
617      - in ggl90_cal.F: compute only one set of visc/diff, used to
618        step forward TKE/T/S/momentum
619      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
620        have Prandlt =1)
621    o gmredi (fm07):
622      - add lower limit on Transition layer thickness + lower limit on 1/lambda
623      - allow to set few more params from data.gmredi
624    o pkg ggl90:
625          - add missing sqrt(2) factor in computation of mixing length
626            scale in ggl90_calc.F
627            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
628    
629    checkpoint61d
630    o adjoint modifs
631      - adapt to new field rhoInSitu
632      - allow to revert from StoreDynVars2D, StoreDynVars3D
633        to individual fields
634        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
635    o store 3-D (in-situ) density in commom block (DYNVARS.h)
636     - save 1 rho computation.
637     - no longer modify T & S inland when using down_slope pkg.
638    o gad_som : allow to switch to SOM advection for T & S without corresponding
639      pickup files (using new S/R: MDS_CHECK4FILE).
640    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
641      (for useSingleCpuIO to work in multi-threaded)
642    o pkg/shelfice:
643     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
644       with SHELFICEtopoFile in data.shelfice
645     - move code for reading ice shelf topography and modifying hFacC into separate
646       subroutines of the shelfice package
647     - separate initialisation of "fixed" and "variable" variables
648     - kTopC is not (yet) replaced by kSurfC, although this is possible
649    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
650    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
651      and rename:
652      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
653      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
654    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
655    
656    checkpoint61c
657    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
658      to add mass source/sink of fluid in the interior (3-D generalisation
659      of oceanic real-fresh water flux).
660    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
661    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
662    o new pkg: down_slope
663      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
664      - presently, modify T & S inland (dwnslp_calc_rho.F).
665        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
666      - implementation for ocean in P-coords not tested.
667      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
668    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
669      (to facilitate conversion of oceanic pkg to p-coordinate).
670    o change FIND_RHO to FIND_RHO_2D :
671      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
672    o new pkg: cheapaml
673    
674    checkpoint61b
675    o exch2:
676      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
677      - no longer depend on the order sequence (N,S,E,W).
678      - 3rd exchange no longer needed (tested with 24 tiles).
679      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
680      - exch_UV_A-grid readily available (but not yet tested).
681      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
682      (both are no longer needed) in exch_uv: no effect in forward run; but
683       get truncation error differences with adjoint exch.
684    o exch2:
685     - change index-bounds storage (moved from target to local tile,
686       more intuitive this way) ; rename/remove some variables.
687     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
688    
689    checkpoint61a
690    o exch2/matlab-topology-generator:
691      fix bug in index bounds for N-S internal exchange (hard to tell if this
692      had any effect on the solution).
693    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
694      is exceeded
695    o testreport: modify syntax of awk, so that it works also with
696      awk, and not only with nawk and gawk
697    
698    checkpoint61
699    o autodiff
700      Change default for TAF usage by removing argument '-nonew_arg'
701      This changes TAF subroutine argument list (ordering of active var.)
702      Omission of this flag leads to incompatibility w.r.t. TAMC
703      To restore TAMC-compatibility, need following modifs:
704      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
705      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
706      Tested TAF version is 1.9.22
707      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
708    
709    checkpoint60
710    --->>> This is the last checkpoint for which generating the adjoint
711    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
712    --->>> by default.
713    --->>> Future checkpoints will ommit this flag by default.
714    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
715    o pkg/grdchk: Add gradient check to etan0 perturbations.
716    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
717    o pkg/autodiff: more flexibility in zeroadj.
718      model/src: modifying do_oceanic_phys.F accordingly.
719    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
720    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
721      special setup of gmredi for which the adjoint is stable
722      enough for parameter optimization.
723    o bridging the gap between eddy stress and GM.
724      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
725          along with a change in CPP option (now ALLOW_EDDYPSI).
726      -> when using GM w/ GM_AdvForm:
727          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
728          is applied either in the tracer Eq. or in momentum Eq.
729          depending on data.gmredi (intro. GM_InMomAsStress).
730      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
731      The key modifications are in model/src/taueddy_external_forcing.F
732      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
733    
734    checkpoint59r
735    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
736      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
737      fix option to read coriolis(@ cell-corner) from files with CS-grid.
738    o pkg/mnc: add some attributes to standard 1D-coordinate variables
739    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
740      mass points, when using mnc for output
741      - add runtime parameter (missing_value, missing_value_int) to override
742        default (which is the value of getcon('UNDEF'))
743    o pkg/mnc: prepare mnc for the actual use of missing values with the
744      diagnostics package: small fix in mnc_cw_readwrite.template and more
745      initialisation of never used fields
746      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
747      versions
748    o pkg/thsice/thsice_ini_vars.F added default initial values so that
749      thermodynamics sea ice solver does not blow up when some initial fields
750      are missing.
751    o move from external_forcing_surf.F to ini_forcing.F
752      the p-coord. hack consisting in using pLoad to set phi0surf ;
753      update output of tutorial_global_oce_in_p (affected @ truncation level).
754    o Freshen up a bit hs94.1x64x5, notably:
755      remove rotationPeriod and tRef=5*0. (adjoint only), and add
756      exactConserv=.TRUE.
757    o pkg/generic_advdiff:
758      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
759      applies to files where Temperature & Salinity 2nd Order moments are used.
760    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
761      this uses a dynamically allocated internal state data structure
762      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
763      and requires a fortran 90 compiler
764    
765    checkpoint59q
766    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
767       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
768    o Refresh tutorial_global_oce_biogeo, notably:
769      - change bathymetry (put back seamounts in ACC, use hFacs)
770      - change EOS (POLY3 --> JMD95Z)
771      - use Bryan-Lewis vertical diffusivity
772      - use multidimensional advection
773      - remove old virtual virtual in dic pkg, now done through ptracer pkg
774      - change a couple of parameters in dic pkg
775    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
776    o pkg/obcs: change default to OBCSfixTopo = .true.,
777      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
778      - replace "debugMode" with "debugLevel .GE. debLevB"
779    o implementation of TAF directives for gchem,cfc,dic
780    o remove "exp5" (replaced by tutorial_deep_convection).
781    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
782      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
783      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
784      --> changes results in exp4, seaice_obcs
785    o tutorial_deep_convection :
786      update the set-up and increase resolution and domain size ; start
787      from pseudo initial conditions = output at t=120mn in order to see
788      something happening when running testreport.
789    o pkg/seaice: add os7mp as an advection scheme
790                  add check for advection schemes
791                  add a flag for restoring T and S underneath sea ice
792    o pkg/my82: add netcdf-support and diagnostics
793    o thsice pkg:
794      - Now hsMax limits snow height by turning it into ice following
795        flooding scheme (and now conserving energy)
796      - Slight rewriting of the formula in thsice_calc_thick.F
797      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
798      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
799    
800    checkpoint59p
801    o gchem / dic / cfc :
802      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
803      - add new parameter files: "data.dic" & "data.cfc" ;
804      - various re-arrangement in initialisation & header file ;
805      - fix tutorial_global_oce_biogeo for multi-threaded test.
806    o pkg/dic: test for "pickup_dic" file when restarting ;
807      if no pickup-file, can restart with a re-initialised pH (same as it did
808      before) providing pickupStrictlyMatch is set to False.
809    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
810      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
811    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
812      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
813    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
814     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
815       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
816    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
817       scheme to use for vorticty-term ;
818     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
819       (with default selectVortScheme, return to original discretisation)
820     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
821    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
822    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
823      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
824      also fix diagnostics VISCAHW & VISCA4W.
825    
826    checkpoint59o
827    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
828    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
829      move a few statemens out the main loop into separate loops
830    o pkg/shelfice:
831      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
832        (kg/m^2/s), does not break tests, because in verification/isomip,
833        rhoConstFresh=rhoConst (by accident)
834      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
835      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
836        new file model/src/seawater.F, so that they are available for all pkgs.
837      - convert potential temperature into in-situ temperature. This changes the
838        isomip tests => update tests
839    o add a flag writePickupAtEnd (default=true) to be able to suppress
840      writing a pickup at the last timestep
841    o tools/mpack-1.6 :
842      - disable automake (not working) and autoconf (not needed).
843      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
844        also cleaner with much less compilation warnings.
845    o pkg/profiles:
846      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
847      (for "less than 32 characters name" compiler requirement)
848    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
849      conditions that have a different sampling frequency than S/T/U/V obcs
850    o pkg/diagnostics (stats-diags):
851      - fix global Min/Max in case 1 processor get only empty tiles
852    o genmake2: replace (4 times)
853         make genmake_tc_1.o >> genmake_warnings 2>&1
854      with
855         COMM="$CC $CFLAGS -c genmake_tc_1.c"
856         echo $COMM >> genmake_warnings
857         $COMM >> genmake_warnings 2>&1
858      to make genmake2 always see the value of CC as specified in the optfile.
859    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
860      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
861      - modify verification advect_cs test to test SOM-advection on CS-grid.
862    o pkg/ctrl:
863      - Rewrite of ctrl_map_ini_ecco.F,
864        introducing a generic routine (ctrl_map_ini_gen.F).
865      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
866    
867    checkpoint59n
868    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
869      number in dedicate array "hdiag":
870      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
871        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
872      - many small changes (integer format) for large number of diagnostics
873      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
874        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
875    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
876      usingSphericalGrid, this allows to define the rotated grid coordinates
877      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
878      geographical coordinates according to the inverse of the rotation defined
879      by the Euler angles, so that Coriolis parameter and online-interpolation by
880      exf works with the geographical coordinates on XC/YC/XG/YG.
881      Naturally, this feature does not work with all packages, so some
882      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
883      profiles), because there the coordinates are assumed to be regular
884      spherical grid coordinates.
885    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
886      - introduce isopycnal diffusion coefficient control.
887    o tools/adjoint_options:
888      - additional control vector components.
889    o pkg/mnc: have mnc create marginally meaning full coordinate variables
890      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
891    o pkg/mypackage:
892      - add example of read/write pickup for state-var ;
893      - add entry points to the main code for state-vars diags & write-pickup.
894    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
895      transitions for useExfYearlyFields
896      - add new subroutine that determines the file to read from for
897        use*YearlyFields = .TRUE. and .FALSE.
898      - add a verification experiment to global_with_exf that tests
899        useExfYearlyFields with USE_EXF_INTERPOLATION defined
900    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
901      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
902      subroutines (which could be generated from a template, because they are
903      almost identical), for now they are included in obcs_prescribe_read.F for
904      simplicity
905    o pkg/exf:
906      - add a little more diagnostic to exf_interp_read (in analogy to
907        mds_read_field, can be turned off with debugLevel < debugLevA=1)
908      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
909        ugly but fast by unrolling short inner loops, inserting a unroll=8
910        directive in routine lagran, and splitting a loop and making do while the
911        outermost loop (the latter requires the intoduction of index arrays)
912    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
913    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
914      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
915    o verification/seaice_obcs: updated for restart test and latest options
916    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
917      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
918      for now this is only available for the C-grid code and also within
919      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
920    
921    checkpoint59m
922    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
923      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
924    o gad_som : fix flux output (& diagnostics) to have same units as other  
925      advection scheme fluxes (was previously multiplied by deltaT).  
926    o added verification/seaice_obcs both to test seaice open boundaries
927      and to provide an example matlab scrpt for generating them
928    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
929    o pkg/salt_plume: clean up salt_plume_frac.F to
930      remove redundancy in PlumeMethod 1 and 4
931    o pkg/kpp: added saltplume diagnostics
932    o pkg/obcs and pkg/seaice:
933      - do not set uice and vice to zero when OB*icefile are unspecified
934      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
935      - moved seaice tracer obcs after call to seaice_growth
936    o pkg/salt_plume: added various options for salt plume depth
937      criterion and for vertical distribution of the salt
938    
939    checkpoint59l
940    o pkg/ptracers: new version of ptracers pickup:
941      read meta file and write only fields which are needed to restart.
942      ( same logic as main pickup file ; also using pickupStrictlyMatch )
943    o pkg/seaice:
944      - add timescale for melting due to warm mixed layer as a means of
945        setting SEAICE_availHeatFrac more conveniently
946      - add a CPP-flag/runtime parameter check for flooding algorithm
947      - reformulated availHeat in seaice_growth.F to be independent of AREA
948    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
949      unit changes
950    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
951    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
952      SX vector computer.
953    o pkg/seaice:
954      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
955        seaice forcing fields can now be read only through pkg/exf
956      - removed some unused halos
957    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
958    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
959      or U/VICE from U/VWIND before computing U/VSTRESS
960    
961    checkpoint59k
962    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
963      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
964    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
965      all experiments pass when compile with un-initialised var. checking option.
966    o added pkg/salt_plume
967    o script to test restart (for now, in MITgcm_contrib/jmc_script)
968    o pkg/seaice: new read/write pickup version.
969      read meta file and write only fields which are needed to restart.
970      ( same logic as main pickup file ; also using pickupStrictlyMatch )
971    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
972    o lab_sea.hb87: modify the domain & update output.hb87.txt :
973      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
974      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
975      process. Fixed here by closing the domain at the Northern boundary.
976    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
977    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
978      a set of consecutive levels in/from a 3-D array.
979    o pkg/ptracers:
980      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
981      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
982    
983    checkpoint59j
984    o in pkgs: dic, obcs, offline, rbcs:
985      standard way to compute coeff. for time interpolation between 2 time reccords
986      which retains full precision (& make results less dependent on compiler).
987      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
988    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
989      packages instead of reading ice cover and wind speed separately
990    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
991     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
992      to allow to compile customized code before the update)
993    o cleaning-up:
994      - fix CPP instruction syntax in pkg/obcs
995      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
996        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
997      - fix some threads issue in IO parts.
998    o pkg/dic:
999      - add tons of "_d 0" (--> much better testreports !)
1000       and then update outputs of tutorial_global_oce_biogeo
1001    o pkg/mom_fluxform:
1002      add a special version of momentum advection intended to conserve momentum
1003      next to a bathymetry step or a coastline edge. (default = off = #undef)
1004    o new read/write pickup version:
1005      - for now, only implemented for main (mdsio) pickup file.
1006      - write out only what is needed to restart; merge pickup_nh , pickup_ph
1007        and main pickup together.
1008      - read meta file; read only what is needed to restart; stop if a field
1009        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
1010        if it make sense (even if the restart is not perfect).
1011      - if no meta file, assume that pickup to read corresponds exactly to
1012        a pickup that would currently be written.
1013      - read pickup written in the old format (until checkpoint59i) if it
1014        recognizes an old meta file (no field-list).
1015      - add a meta file in exp. which starts from a pickup: 2 cases:
1016        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
1017         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
1018        b) a meta file describing the content of the associated pickup file
1019         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
1020    o pkg/mdsio & pkg/rw:
1021      - new routine to read a meta file ; new set of routine to read
1022        Multiple-fields file (with meta file).
1023    o added open boundary conditions capability for seaice
1024        HSNOW, HSALT, UICE, and VICE
1025    
1026    checkpoint59i
1027    o adjoint:
1028      * fix multiDimAdvection adjoint
1029        (partial recomputation problem by TAF for fVerT(:,:,kDown)
1030        and comlev1 size definition (maxpass vs. max. number of tracers)
1031      * verification/global_ocean.90x45x15 adjoint now tests
1032        NLFS and multiDimAdvection using DST3 (=30)
1033      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
1034    o pkg/kpp: add "_d 0" to real constant (if missing);
1035      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
1036      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
1037    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
1038      for internal parameters related to restart process (formerly from PARAMS.h)
1039      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
1040    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
1041      as argument. (only atm2d & obcs write_pickup have not yet been updated)
1042    o pkg/monitor:
1043      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
1044      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
1045      - account for deep Atmosphere factor and density factor (anelastic)
1046    o added open boundary conditions capability for seaice HEFF and AREA
1047    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
1048      thermodynamics
1049      - requires a little reorganization, which affects the testreport results
1050        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
1051        so that now the conservative form is tested
1052      - add a few comments
1053    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
1054    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
1055    o add new diagnostics to seaice: advective, diffusive fluxes (only for
1056      multidim-advection, for scheme 2 they are not filled) and transports,
1057      thermodynamic growth rates
1058    o change units of EmPmR (inside the code, + within coupling interface)
1059      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
1060      Affects results @ truncation level (cg2d match) and update output of
1061       experiments: lab_sea(6), global_ocean.90x40x15(10),
1062      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
1063      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
1064      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
1065      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
1066    
1067    checkpoint59h
1068    o pkg/exf:
1069      - improve vectorization by moving if-statement out of loops in
1070        exf_mapfields, exf_radiation
1071      - exf_bulkformulae.F: introduce 2D fields and vectorize code
1072    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
1073    o testreport:
1074      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
1075        monitor & update offline_exf_seaice exp. output.
1076      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
1077    o pkg/seaice:
1078      - bug fix in the evp solver: boundary conditions were affected be
1079        masking of zMax/zMin (changes results)
1080      - minor bug fix in boundary conditions in seaice_calc_strainrates
1081        (changes results for no_slip)
1082      - seaice_lsr.F: make interpolation of eta dependent on boundaries
1083      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
1084      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
1085        stress formulation and no-slip boundary conditions
1086    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
1087      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
1088    o pkg/seaice: a first HSALT time stepping equation has been checked in
1089    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
1090      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
1091      without requiring DO-IF statements
1092    o pkg/thsice:
1093      use continuous power-law function for partition of energy between lateral
1094      melting/freezing and thinning/thickening ; old code using step function
1095      still available with #undef THSICE_FRACEN_POWERLAW
1096      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
1097    o testreport: change AD testing : check against results/output_adm.txt
1098      using same scripts as for forward test.
1099    
1100    checkpoint59g
1101    o adjoint testing: in preparation for changing testreport:
1102      - output format: cost and grad written on separated lines
1103      - ad output results in directory "results" (instead of "results_ad")
1104    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
1105    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
1106    o pkg/ecco: allow user defined cost function contributions
1107    o testreport:
1108      Allow to choose (per experiment) the list of tested output variables
1109       and the main variable (used to issue a pass/FAIL ) ;
1110      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
1111      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
1112      Also modify printing of summary:
1113       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
1114       b) echo the list of tested variables in the individual summary.txt of
1115          each experiment.
1116    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
1117      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
1118      (but still depend on the tile decompostion of the domain).
1119    o pkg/seaice: change a discretization detail to make the B-grid code
1120      "more symmetric". This change is likely to remove all "ridges/leads" that
1121      where quasi-aligned with the grid in B-grid solutions. It may also be
1122      the solution to the stress coupling issues with the B-grid.
1123    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
1124      remove .cvsignore from input dir. (since testreport no longer run here).
1125    o pkg/thsice:
1126     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
1127     - fix reshaping of sea-ice just after advection:
1128       melt all the ice only if ice-volume is too small.
1129     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
1130       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
1131     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
1132    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
1133      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
1134    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
1135      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
1136      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
1137      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
1138      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
1139      -> update output.txt
1140    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
1141     this affects truncation error: -> update output.txt of exp:
1142      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
1143      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1144    
1145    checkpoint59f
1146    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1147    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1148      a bounded range (in forward mode)
1149    o pkg/ecco, ctrl, autodiff and mom_common:
1150     internal parameter controls, completements of implementations
1151    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1152    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1153      (not seem any difference in testing results).
1154    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1155       at face corners.
1156    o pkg/generic_advdiff:
1157     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1158      loop range indices for computing vertical advection tendency
1159      and do the calculation in the interior only (no overlap) ;
1160      for now, only implemented for SOM advection (to save CPU time).
1161     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1162    o exch2 adjoint
1163      First set of changes:
1164      - add exch2 hand-written adjoint templates
1165      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1166        This will require cleanup in pkg/autodiff/*.F
1167        (changed routines currently kept separate in verif. code/)
1168      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1169        that used to hide exch2 or cubed-sphere specific code
1170        (commented via 'cph-exch2')
1171    o pkg/seaice
1172      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1173    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1174       output of global_ocean.cs32x15.thsice .
1175    
1176    checkpoint59e
1177    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1178      for B-grid vector (not yet tested) and C-grid vector (<- only used
1179      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1180    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1181      (#ifdef ALLOW_SALT_PLUME)
1182    o gather_2d/scatter_2d: removed halo regions
1183    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1184      scheme and the corresponding test case (under front_relax dir). For now,
1185      only available with Skew-flux form and not yet tested in realistic set-up.
1186      adjoint: store directives updated, but gradient checks deteriorated,
1187      so maybe GM/Redi adjoint is now broken.
1188    o seaice adjoint
1189      * add AREA, HEFF, HSNOW as control variable
1190        (should not change lab_sea results)
1191      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1192    o pkg/seaice:
1193      * added computation of saltFlux in seaice_growth;
1194        For time being, sea ice salinity is assumed constant
1195        contribution of snow flooding to freshening of sea ice is neglected.
1196        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1197        defaults to 0.0 in order to maintain backward compatibility.
1198        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1199      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1200      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1201        heat content used to melt or grow ice
1202      * commented out cap of HICE: it helps keep ice thinner
1203      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1204      * applied OBCS T/S mask to HEFFM sea ice mask
1205    
1206    checkpoint59d
1207    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1208     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1209     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1210    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1211     and change default value of parameter "GM_Small_Number";
1212     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1213       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1214       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1215    o pkg/ecco: cost function when applying pkg/smooth to controls
1216    o pkg/ctrl: add forcingPrecond run time parameter
1217    o pkg/seaice:
1218     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1219     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1220       changes verification/lab_sea
1221     - rearrange implicit part of u-equation in LSR solver to make it easier to
1222       read, understand, and debug. This causes changes at the truncation level.
1223     - fix (serious) bug in the boundary conditions (sign error in the implicit
1224       part) of the LSR solver. Changes all LSR results.
1225     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1226       is initilized with small values - does not change lab_sea results.
1227     - added HsnowFile initialization capability
1228    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1229     initialization of pkg/smooth and application to control vector
1230    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1231    o dependencies: pkg/profiles requires pkg/cal
1232    o pkg/profiles:
1233     - added option ALLOW_PROFILES_GENERICGRID
1234         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1235         that interpolation information (grid points and coefficients) is provided
1236         within the netcdf input files.
1237         -> sample matlab scripts can be found in MITgcm_contrib/gael
1238         that allow you to prepare netcdf input files.
1239     - also modified: cleaner include statements, cleaner error print statements,
1240       cleaner stops when error, and more tests of the netcdf input files consistency.
1241    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1242    o pkg/seaice:
1243     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1244       requires a new routine: seaice_diagnostics_fill.F
1245     - make sure that seaice does not move if not forced (pressure replacement
1246       method, Hibler and Ip, 1995), changes results
1247     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1248     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1249       It is turned off by default (=-1.), because it changes the results.
1250     - make it possible to read AREA from a file, too.
1251    
1252    checkpoint59c
1253    o add S/R and diagnostics for oceanic mixed-layer depth
1254    o move GMRedi call after all vertical mixing schemes (including KPP)
1255    o pkg/thsice:
1256     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1257      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1258    o pkg/obcs:
1259     - bug fix for balance code
1260    o pkg/seaice:
1261      - allow values of SEAICE_elasticParm > 1
1262      - add new parameter SEAICE_evpTauRelax as an alternative
1263        to SEAICE_elasticParm
1264      - make lsr boundary conditions free slip (by default), changes result
1265      - add code for no slip boundary conditions for lsr
1266      - set minimum of zeta to zero (and not 4e8) (changes results)
1267      - add a cap on AREA after advecting AREA if seaice_growth is not called
1268    o change calculation of Visbeck K:
1269      - no longer depend on tapering scheme; instead, compute slope (limited
1270        by GM_maxSlope). this is equivalent to what was comuted before with
1271        clipping or linear tappering.
1272      - fix vertical averaging (wrong by 1/2 level)
1273      - leave the old version (but will not be maintained) within
1274        #ifdef OLD_VISBECK_CALC / #endif
1275      - update output of exp. ideal_2D_oce
1276    o change error catch in calc_r_star to improve vectorization
1277    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1278      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1279    o adjoint:
1280      Re-organized adjoint checkpointing according to Matt Mazloff
1281      (but with modifs/completions/cleanups)
1282      Storing is now bundled into large arrays to optimized I/O
1283      (and second step in cleanup of the_main_loop)
1284    
1285    checkpoint59b
1286    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1287      - export/import (between ocean & coupler) fields needed for ocean DIC.
1288    o pkg/seaice:
1289      - get rid of three more exchanges seaice_calc_viscosities (required
1290        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1291      - bug fix in seaice_ocean_stress (update of lab_sea required)
1292      - reduce loop boundaries to necessary minimum also in seaice_evp
1293      - go back to the old way of computing deltaC/Z as the adjoint likes that
1294        better
1295    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1296      passive tracer to an Age Tracer) + update output.txt
1297    o pkg/exf:
1298      - implement A-grid / C-grid selection for wind-stress input files.
1299      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1300      for now, in exf_bulk_largeyeager04.F only :
1301      - change implementation for case where windspeed + 2. components wind-stress
1302        are read-in. AND use rhoConstFresh to convert evap.
1303    o pkg/seaice:
1304      - use correct EXCH_UV for wind-forcing (on A-grid).
1305      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1306        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1307    o pkg/exf:
1308      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1309      EXF_INTERPOLATION:
1310      - merge global_with_exf/code version of exf_interp_read.F
1311        to the main code ;
1312      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1313        reading the file ; Important: This options needs to be defined to recover
1314        previous code.
1315        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1316      - no longer loose real*8 precision along the way when using exf_iprec=64.
1317    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1318      - change discretisation of evp-solver in order to avoid another exchange
1319        (changes lab_sea) and clean up a little
1320      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1321        help the adjoint (this also changes the results slightly)
1322      - add a few "_d 0" where they had been missing in seaice_evp.F
1323      - cleaning up: remove unused seaice_calc_rhs.F
1324    o pkg/exf: some cleaning-up:
1325      - change various "constants" into runtime parameters
1326      - cleaned-up Large&Yeager04 routine which should eventually
1327        replace exf_bulkformulae.F (changed names of S/R and CPP)
1328        and merged various ALLOW_ATM_WIND options
1329     only used with thsice pkg (in thsice_get_exf.F):
1330      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1331        which are used when useStabilityFct_overIce=TRUE (= the default)
1332      - change default values of ice & snow emissivity and scale downward LW
1333        by ice & snow emissivity.
1334    o pkg/thsice:
1335     fix few little problems, in thsice_calc_thickn.F:
1336      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1337      - melt only laterally if hIce < hThinIce (as the comments say)
1338      and in thsice_extend.F:
1339      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1340      - start to form ice as soon as the minimum ice-volume is reachable.
1341     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1342      and cpl_aim+ocn
1343    o pkg/kpp
1344     - move computation of surface related input fields to KPP into a new
1345       subroutine kpp_forcing_surf.F
1346     - remove wrong (within bi,bj loops) EXCH calls.
1347     - little cleaning (add argument myThid in last position, cvs header ...)
1348     - for now, fix conservation problem by exchanging KPPviscAz (may not
1349       be the best fix)
1350    o pkg/seaice
1351     - check for inconsistent evp parameter/cpp-flag combination
1352     - remove leftover errIO flat for obsolete name list error handling
1353    o OpenAD
1354     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1355    
1356    checkpoint59a
1357    o pkg/seaice: some parameter clarifications and a little bit of clean up
1358    o pkg/thsice: rename run-time parameters:
1359       himin       -> hIceMin
1360       himin0      -> hThinIce
1361       hihig       -> hThickIce
1362       i0          -> i0swFrac
1363       transCoef   -> bMeltCoef
1364       frac_energy -> fracMelting
1365      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1366       with default values (for now) that do not change the results.
1367      remove old version of thsice vars advection in pkg/seaice.
1368    o in FFIELDS.h:
1369      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1370      - make pLoad & sIceLoad always available (but still only used if
1371         ATMOSPHERIC_LOADING is #define).
1372    o pkg/kpp: replaced _KPP_RL with _RL
1373    o bug fixes for vertical diffusivity computations when both KPP and
1374        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1375        are no longer updating the vertical diffusivity array
1376        (passed as argument) but are (re-) setting those arrays.
1377    o pkg/seaice: fix bug in evp solver, while doing that
1378      - change (improve?) discretization of stress computations for both
1379        cgrid-lsr and evp solver
1380      - add a new routine to compute strain rates
1381      - the above changes lab_sea results
1382      - add no slip conditions for evp solver (off by default), lsr-version
1383        may follow
1384      - fix exchange for shear at Z-points (does not change lab_sea)
1385      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1386        (to force the user to pick a time step since there is not "safe" way
1387        of choosing it)
1388      - add principal stress diagnostics
1389      - rearrange fields for evp a little to avoid having to call a: too many
1390        exchanges and b: exchanges for stress trensor components which we do
1391        not have.
1392      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1393        of evp, complete rewrite for lsr case (latter is does not yet work
1394        in all cases)
1395    o pkg/kpp: add code to have mixing in shelf ice caverns
1396      - add myThid to all kpp routines (long overdue)
1397    
1398    checkpoint59
1399    o pkg/exf:
1400      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1401        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1402      - move exf header files from lower_case.h to UPPER_CASE.h ;
1403        add missing cvs Header & Name
1404      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1405      - add namelist param. selectStressGridPosition, exf_monFreq
1406      - retire many _CLIM routines, and remove data.exf_clim
1407        + params moved to data.exf
1408        + climsst, climsss now handled by exf_set_gen, i.e.
1409          climss?period=0 refers to constant field,
1410          climss?period=-12 to monthly forcing
1411      - split up namelists in data.exf
1412    o pkg/seaice:
1413      - remove seaice_exch and seaice_exch_uv
1414      - remove superfluous exchange of theta
1415      - add myThid to seaice_budget_ocean/ice
1416      - add new interface for atmospheric wind forcing (C-grid only)
1417        + new routine
1418        + two new field (taux, tauy for stress over ice)
1419        + removed one global field (DAIRN) for C-grid case only
1420    o pkg/thsise
1421      - 2nd set of modifs for thsice adjoint in conjunction with exf
1422    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1423    
1424    checkpoint58y_post
1425    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1426      vertical diffusivity, similar to that in MOM4; turned on using
1427      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1428      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1429    o Added capability for 3D specification of background vertical diffusion
1430      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1431      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1432      "data" file that contains the 3D vertical diffusivity coefficients.
1433    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1434      - add code within pkg thsice to advect & diffuse sea-ice fields
1435      similar to (and will replace) what has been added in  seaice_advdiff.F,
1436      but: - conserving Mass, Heat & Salt.
1437           - better when using non-linear advection scheme (not yet fully tested)
1438           - can also be used in atmospheric set-up (for now, only the diffusion).
1439    
1440    checkpoint58x_post
1441    o IO option for global-file compact format:
1442      - add options when generating topology (utils/exch2/matlab-topology-generator)
1443      - add I/O capability (pkg/mdsio).
1444      - adapt utils/matlab/rdmds.m to read this format.
1445      for now long-line format not yet supported by pkg/mdsio (& exch2).
1446    o shelfice: add a few diagnostics
1447    
1448    checkpoint58w_post
1449    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1450      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1451      (and replace horiVertRatio in NH code).
1452      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1453                         and tutorial_plume_on_slope (sensitive to truncation)
1454    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1455      directly to drive seaice model (C-grid only)
1456    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1457     - reintroduce computation of wind from stress,
1458     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1459       mass points to avoid tau = 0
1460     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1461    o rdmnc.m: make it work with "global" files created with gluemnc
1462    o rdmnc.m : some improvements in dealing with singleton dimension
1463      (tested on all testreport mnc output files).
1464    o genmake2: disable pkg/profiles if netcdf test fails.
1465    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1466    o move call to cal_readparms up to make calendar parameters/variable available
1467      to all packages
1468    
1469    checkpoint58v_post
1470    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1471      useDynP_inEos_Zc tested.
1472    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1473    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1474      and portions thereof.  See read_cs.txt for description and examples.
1475    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1476      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1477      following the great-circle arc between those 2 points.
1478    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1479      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1480    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1481     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1482     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1483     - still needs work (not working with some options ; efficiency to improve)
1484       and serious testing.
1485     - use this scheme for temperature & salinity in 2 advection test exp.:
1486       advect_xy & advect_xz, respectively.
1487    
1488    checkpoint58u_post
1489    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1490    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1491    o testreport: add option "-skipdir" to skip some test.
1492    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1493      momentum calculation.
1494    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1495    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1496      remove checkpoint.F and the_correction_step.F (no longer used);
1497      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1498    o add option (linFSConserveTr) to correct for tracer source/sink due to
1499      Linear Free surface
1500    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1501    o pkg/thsice: fix reading mnc-pickups
1502    
1503    checkpoint58t_post
1504    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1505    o pkg/mdsio:
1506     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1507       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1508       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1509     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1510     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1511       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1512     - new S/R (to replace MDSWRITEMETA), which allows to write more
1513       informations (variable names, time ...) to meta files.
1514     - modify rdmds.m to give back the meta file content.
1515    o pkg/diagnostics: change vertical interpolation to be safer, and more
1516       flexible (define p-levels to interpolate to in data.diagnostics);
1517      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1518       diagnostic pointer.
1519    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1520    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1521    o fix multi-category seaice:
1522     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1523       SEAICE_MULTICATEGORY
1524     - fix short wave heat flux
1525    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1526       and allow to use EVP solver. Change forward lab_sea: test both EVP
1527       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1528    o Initial check-in of lab_sea adjoint
1529      (very similar to natl_box_adjoint/code_seaice)
1530      * used C-grid and EVP solver
1531      * used KPP, GM/Redi
1532      * uses inAdExact=.TRUE.
1533      * gradient checks fail for both ADM and TLM
1534        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1535        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1536        issue is related to forward mismatch between g77 an ifort
1537    o pkg/seaice: overhaul of thermodynamics
1538     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1539     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1540     - move a few global fields out of SEAICE.h into seaice_growth.F and
1541       make them 2D (FICE/QNETO/ ...)
1542     - remove FO (it is the same as QNETO)
1543     - introduce a few local fields to avoid modifying external fields such
1544       as atemp, etc.
1545    
1546    checkpoint58s_post
1547    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1548      changed exf_set_gen.F so that
1549        genperiod=0 means input file is one time-constant field and
1550        genperiod=-12 means input file contains 12 monthly means
1551    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1552      this affects truncation error ; generate new output file for exp. which
1553      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1554        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1555        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1556        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1557        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1558        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1559    o start implementation of deep-atmosphere and anelastic formulation
1560    o verification: remove 2nd copy of input files and use script "prepare_run"
1561      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1562    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1563    o profiles: fix for multithreaded case
1564    
1565    o diagnostics: rename few diags:
1566      s/'PRESSURE'/'RCENTER '/g
1567      s/'TICE    '/'oceFreez'/g
1568      s/'TAUX    '/'oceTAUX '/g
1569      s/'TAUY    '/'oceTAUY '/g
1570      s/'SWFLUX  '/'oceQsw  '/g
1571      s/DIFx/DFxE/g
1572      s/DIFy/DFyE/g
1573      and add few ocean-forcing diagnostics:
1574      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1575    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1576      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1577      as actual snow thickness.  It now refers everywhere to effective snow
1578      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1579    
1580    checkpoint58r_post
1581    o modifications to pkg/seaice/growth.F, which change results of
1582      lab_sea experiment: fixes pertain to melting snow over open water, to
1583      masking EVAP under sea ice, and to using the correct AREA variable for
1584      computations of EVAP, PRECIP, HSNOW, and GHEFF
1585    o add ability to read bathy, salt, and theta using MNC (off by def)
1586    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1587      both are turned off by default and do no change any results
1588    o seaice advection with pkg/thsice: a step toward the use of non-linear
1589      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1590    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1591      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1592      in natl_box (affects results @ truncation level: update output.txt)
1593    o multi-threading and IO:
1594      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1595      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1596        (needed to work with SingleCpuIO): tested in all verif. exp.
1597    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1598      affects the results (but none of the verification test uses this scheme).
1599    o Adding some pkg/diagnostics capability to pkg/seaice
1600      (will certainly be subject to changes)
1601    o ctrl: adding new control variables:
1602      lwflux, lwdown, evap, snowprecip, apressure, runoff
1603    
1604    checkpoint58q_post
1605    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1606      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1607      high_res_cube configuration by 4% on Columbia.
1608    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1609      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1610      dynamical allocation (seems to work in multi-threaded).
1611    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1612      single CPU io) so that TAF does not have to see EESUPPORT.h
1613    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1614    
1615    checkpoint58p_post
1616    o obcs: stop if obcs is used with useCDscheme = .true.
1617    o shelfice:
1618     - fix a sign error so that no slip at shelfice interface works
1619     - remove stop for combination non-hydrostatic code and shelfice. That does
1620       not mean, that the results are correct, but at least they are numerically
1621       stable
1622    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1623    o added adjoint exch routined for all exch*3d* routines
1624      and updated flow directives
1625    
1626    checkpoint58o_post
1627    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1628      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1629    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1630      and clean-up reading/writing of pickup files.
1631    o fix local version of read/write pickup (NH part) in rotating_tank/code
1632    o simplify EXCH interface:
1633     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1634     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1635    o added the regrid package
1636    o shelfice:
1637     - add a simple boundary layer scheme to reduce noise
1638     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1639    
1640    checkpoint58n_post
1641    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1642       local variable (not in common block).
1643    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1644      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1645      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1646        to work with SingleCpuIO.
1647    o add "_d 0" to real constant of pkg/cfc subroutines ;
1648       update exp. cfc_exemple & tutorial_cfc_offline output files.
1649    o multi-threading and IO:
1650      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1651        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1652      - barrier before and after reading.
1653      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1654      - avoid using MDS_WRITELOCAL for LAND pkg output.
1655      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1656        common-block variables ; Allows multi-threading with master-thread IO.
1657    o change default MAX_NO_THREADS from 32 to 4 ;
1658      and stop cleanly when MAX_NO_THREADS is too small.
1659    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1660    
1661    checkpoint58m_post
1662    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1663       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1664    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1665       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1666       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1667    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1668        add MITgcm_tutorials (= code + all the tutorials)
1669    o ecco, option to compute cost for total ssh (mean+anom)
1670    o consistent with addition of ptracer and ssh in pkg/profiles
1671    o profiles: adding ptracer and ssh
1672    o testreport: change multi-test output-file name
1673      (from output.txt.{name} to output.{name}.txt)
1674    o profiles: now ok for mutli-tiles case
1675    o seaice: add 4 parameters for different advection schemes for area,
1676      (effective) seaice thickness, enthalphy, and snow height. Their default
1677      is the standard parameter SEAICEadvScheme
1678    o calc_gw:
1679     - add cosFacU in zonal viscous flux (harmonic.visc.).
1680     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1681       of tutorial_plume_on_slope.
1682    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1683    o calc_gw: true flux-form, account for horizontal grid spacing.
1684      update rotating_tank results, but not plume_on_slope (affected at
1685      truncation level, 11 digits).
1686    
1687    checkpoint58l_post
1688    o calc_gw:
1689     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1690     - remove side-drag for now (need to fix it); update plume_on_slope results.
1691     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1692    o commit code to make SST/SSS weights spatially variable
1693      (based on either variable in-situ or variable initial T/S weights)
1694    o pkg/ecco:
1695      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1696        now based on horizontally varying weights wthetaLev, wsaltLev
1697      * cost_averagesflags now returns year indices in addition to day, month
1698      * sflux balance is performed on annual basis
1699        (sflxumm, sfluxmm2, bal_sfluxmm)
1700      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1701        including separate counting and multipliers
1702    o pkg/rbcs
1703      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1704    
1705    checkpoint58k_post
1706    o testreport:
1707     - always build in dir. "build" (if not there, mkdir build instead of building
1708       & running in input)
1709     - run in dir run (if it exists), in build otherwise.
1710     - call prepare_run (if input/prepare_run exists)
1711     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1712    o pkg/exf modifications to interpolation and rotation routines for more
1713       reasonable treatment of North Pole singularity: for tracers North Pole
1714       value is set to northernmost zonal-mean value, for zonal velocity it is
1715       set to zero, and for meridional velocity it is set to northernmost value.
1716    o pkg/exf/exf_check_range.F
1717     - add tile index to diagnostics and move stop statement to the very
1718       end of the routine.
1719    o pkg/diagnostics: (diagnostics_main_init.F)
1720      define title of isomorphic variables according to the current config.
1721    o pkg/thsice with pkg/seaice dynamics:
1722    - fix domain of computation (interior only, required for exf) and do exchanges
1723    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1724    o towards a standard way of dealing with multi-threading in MONITOR
1725      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1726    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1727       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1728    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1729    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1730    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1731       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1732    o tracer advection:
1733     - clean-up and simplify calc_common_factors.F
1734     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1735       advection subroutine (but still not used within DST advection S/R)
1736    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1737    
1738    checkpoint58j_post
1739    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1740      from file (collects calls previously in FORWARD_STEP)
1741    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1742    o adjoint store dir. adjusted accordingly
1743    o genmake2
1744      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1745    
1746    checkpoint58i_post
1747    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1748      on wind stress (SEAICEstressFactor defaults to 1.)
1749    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1750      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1751    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1752      on CS-grid: no longer loosing mass.
1753    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1754    o pkg/ggl90: fix sloppy output and fix a bug
1755    o pkg/seaice: added SEAICEuseEVPpickup parameter
1756      - Set to false in order to start EVP solver with
1757        non-EVP pickup files when using SEAICEuseEVP
1758      - fix sign error in diffusion in seaice_calc_rhs
1759    
1760    checkpoint58h_post
1761    * Modifications for bottom topography control
1762      o replace hFacC by _hFacC at various places
1763      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1764      o add non-self-adjoint cg2d_nsa
1765      o update autodiff support routines
1766      o re-initialise hfac after ctrl_depth_ini
1767      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1768    * Adding verification for 5x5 box (4-layer) bottom topography control
1769    
1770    checkpoint58g_post
1771    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1772       used for mean seasonal cycle, mean diurnal cycle); add an example
1773       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1774    o pkg/ggl90:
1775      - add parameter (minimum surface kinetic energy)
1776      - fix bug (avoiding division by zero)
1777    o couple pkg/thsice to pkg/seaice:
1778      - modify advection in seaice to accomodate new scalar fields to be advected
1779      - only muliDimAdection scheme work with seaice/thsice
1780      - mapping of thsice-variables to seaice-variables, back and forth
1781      - does not break the verification experiments, but does not give the
1782        desired results either
1783    o pkg/seaice
1784      - make (default) second order advection a bit less confusing?
1785    
1786    checkpoint58f_post
1787    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1788      to pkg/seaice):
1789      - new routines thsice_map_exf and thsice_get_exf provide the interface
1790      - add an additional formal parameter to thsice_solve4temp
1791    o pkg/exf:
1792      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1793      - correct Stefan-Boltzmann constant
1794      - new parameter for longwave surface emittance
1795      - separate some stuff from exf_bulkformulae into new routines  
1796        exf_radiation, exf_wind
1797      - add new parameters and constants: longwave emissivity for ocean, ice
1798        and snow, evaporation parameters over ice
1799      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1800        either wind from stress or stress from wind
1801    o pkg/thSIce:
1802    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1803    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1804       and THSICE_CALC_THICKN
1805    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1806    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1807      to make debugging easier.
1808    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1809    o pkg/bulk_force:
1810      - clean-up comments and parameters ;
1811      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1812    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1813      generate new output for test-experiment: aim.5l_cs.thSI
1814    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1815      testreport accordingly
1816    
1817    checkpoint58e_post
1818    o SEAICE_CGRID adjoint done
1819    o R_STAR adjoint implemented.
1820      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1821      * need to sort out init. of h0facc, etc.
1822    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1823      to be able to use it in pure forward.
1824    
1825    checkpoint58d_post
1826    o upgrade simple test-experiment to tutorial example:
1827     step.1: duplicate the experiment and (step.2) will remove the old copy.
1828      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1829      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1830      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1831      tutorial_global_oce_biogeo    <- copy of dic_example
1832      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1833      tutorial_plume_on_slope       <- copy of plume_on_slope
1834      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1835      tutorial_global_oce_optim     <- empty for now (David ?)
1836      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1837     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1838    o correct a sign problem in cost_scat.F
1839    o obcs and ptracers: fix boundary conditions for advections schemes
1840      with larger stencil
1841    o thsice adjoint: start
1842    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1843      completeness
1844    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1845      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1846    o ptracers adjoint:
1847      * avoid extensive recomputatations
1848      * fix missing re-init. of gptr (missed by TAF)
1849    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1850      me to turn off the excessive output to STDOUT that this package produces
1851    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1852      and add those terms in Vector-Invariant formulation.
1853    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1854      if the control period (xx_hfluxperiod etc) is 0
1855    o in profiles pkg, clean routines and fix details
1856    o in ecco pkg, reading ssh data:
1857      fix problem in case the model does not start at iter0=0
1858    o fix mnc-pickup/restart for ptracers
1859    o new package prifiles:
1860      code to compute profile-based cost by Gael Forget
1861      (modifs in ecco, ctrl, autodiff)
1862    o Benign bug fix in initialization (spotted by M. Mazloff) of
1863      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1864    
1865    checkpoint58c_post
1866    o adjoint: finish NLFS adjoint and provide reference output in
1867      verification/global_ocean.90x40x15/results_ad_nlfs
1868    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1869      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1870      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1871      with SEAICE_CGRID defined.
1872    o move calendarDumps from "data" to "data.cal" and clean-up the code
1873      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1874    o add useEXF & useCAL flags (for now, set in hard-coded way)
1875    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1876      (were missing in NH mode, and wrong in quasihydrostatic mode).
1877      waiting for Chris updated version of calc_gw to add those CALLs.
1878    o fix bug in quasihydrostatic S/R ;
1879      add a test for this option: global_ocean.90x40x15.qshyd
1880    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1881      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1882    o add on/off flag useOffLine for package OFFLINE
1883    o seaice:
1884      - modify advection so that it works also on the C-grid
1885      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1886        problem in multi-tile runs with C-grid
1887      - add flags for clipping ice velocities and/or masking solver forcing
1888      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1889        C-grid solver
1890      - added a few comments to seaice_diffusion.F
1891      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1892        are now exclusive)
1893      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1894        required re-ordering the code a little:
1895       + make DAIRN global variable (defined in SEAICE)
1896       + move computation of the viscosities eta and zeta into a new separate
1897         routine (because I need to recompute them in seaice_ocean_stress.F)
1898    
1899    checkpoint58b_post
1900    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1901      update output.txt of exp. aim.5l_cs.thSI
1902    o various mnc cleanups and improvements:
1903      + shrink lookup tables by factor of ~4
1904      + better error reporting when running out of lookup space
1905      + able to handle longer path/file names (up to 500 chars)
1906    o adjoint:
1907      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1908      - TBD: "hidden" mom_vecinv recomp. in dynamics
1909    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1910     (allow to differentiate between forcing components using new integer flags:
1911      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1912     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1913    o ecco
1914      - enable trend removal from SSH anomaly obs.
1915    o adjoint
1916      - a fix for PmEpR when #undef EXACT_CONSERV
1917      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1918      - try to fix "hidden" recomp. in forward_step for NLFS
1919        (NLFS seems broken sometimes after I checked it in)
1920    o seaice:
1921     - add c-grid version of the dynamic solver:
1922       + three new routines that are the c-grid substitute lsr, dynsolver
1923         and ostres
1924       + put a few fields that were local to dynsolver into global common
1925         blocks, so that I can move the computation of stresses etc into
1926         seaice_lsr (saves coding but may break the adjoint).
1927     - replace more hardwired parameters by runtime parameters
1928     - add ice masks that mask the rhs of the implicit solvers where there
1929       is no ice (commented out in seaice_dynsolver, because i am not sure
1930       if this works properly), eventually this should replace the clipping
1931       of ice velocities in seaice_dynsolver to +/-40cm/s.
1932    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1933      include it only where its needed
1934    o move balancing of fluxes before the call of external_forcing_surf
1935    o seaice:
1936      - correct units of turning angles (now they are really in degrees)
1937      - move computation of GWATX/Y out of main routine into dynsolver
1938      - initialize GWATX/Y in seaice_init
1939    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1940      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1941    o seaice: add runtime flags for turning angles (default to zero)
1942    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1943      and trend from exf forcing and ctrl control adjustments
1944    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1945      (since checkpoint57x_post)
1946    o change the default rotation period to 86164.s = the Earth rotation
1947    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1948      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1949    o seaice advection: add code for choosing between the default (2nd order
1950      central differences) and multiDim advection schemes provided by
1951      pkg/generic_advdiff
1952    o seaice:
1953      - removed all references to SEAICE_GRID.h fields from
1954        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1955        (cubed-sphere configuration will change a little)
1956      - grid computations in seaice_init are obsolete now.
1957      - cleaned up code a little so that is easier to read (hopefully).
1958      - added new (better?) discretizations of default advection and diffusion
1959        (turn on with SEAICEuseFluxForm)
1960      - replace 1 in 3d global fields by kSurface in growth.F
1961      
1962    checkpoint58a_post
1963    o seaice:
1964      - bug fix in advect.F
1965    o shelfice:
1966      - separate shelfice load anomaly from pload (breaks with time
1967        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1968        Its default is 0., but it may be computed more cleverly from (unknown)
1969        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1970        done offline. A good approximation of the pressure load anomaly is
1971        necessary to avoid large initial adjustment processes underneath
1972        deep-reaching shelfice.
1973      - small fix in ISOMIP shelfice_thermodynamics
1974      - add more sophisticated thermodynamics of Hellmer (1989), this is
1975        now the default
1976      - give a few constants more intuitive names
1977    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1978      if bulk formulae are used in long integration (especially EmPmR). Turn
1979      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1980      if balancePrintMean, the imbalance that is substracted is printed to
1981      STDOUT.
1982    o fix bug (typo) in obcs_apply_eta.F
1983    o add a new package shelfice which enables us to model the circulation
1984      underneath shelf-ice with draughts of hundreds of meters.
1985     - works
1986     - to do: + include improved thermodynamics
1987              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1988                instead of new field kTopC
1989              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1990                instead of new field R_shelfIce and new code in ini_depth.F
1991                and ini_mask_etc.F?
1992              + adjust vertical mixing schemes?
1993    o seaice pkg:
1994     - add a cpp-flag to include a simple formula for a salinity dependent
1995       freezing point of sea water at the surface
1996     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1997       meridional stresses are now different (and hopefully correct)
1998    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1999       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
2000       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
2001    o pkg/diagnostics: add options and parameters for regional-statistics
2002       diagnostics ; define regions by reading a region-mask from a file
2003       (might add other options later)
2004    o pkg/bulk_force:
2005     - add option and parameters to use AIM surface-flux formulae.
2006     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
2007       others forcing fields (defined in PARM05, parameter file "data") are loaded
2008       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
2009     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
2010     - use the right EXCH call for uwind,vwind (to work on CS-grid).
2011     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
2012       and parameters (note: calcWindStress replaces .NOT.readwindstress).
2013     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
2014    
2015    checkpoint58
2016    o add "--embed-source" option to genmake2 which, when the supporting
2017      tools can be compiled (as determined by genmake2) will turn on the
2018      embed_files package which then embeds the entire MITgcm source code
2019      (*.[fFhc] + Makefile) used for the build within the executable
2020      - requested by CNH but off by default
2021      - adds a paltry <9MB to the mitgcmuv executable in most cases
2022      - only writes the output when useEMBEDSRC in eedata is true
2023    o clean up 3-dim. relaxation codes:
2024      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
2025      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
2026      * Thanks to Tom Haine for testing!
2027    
2028    checkpoint57z_post
2029    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
2030      affects output (@ truncation level) of exp. plume_on_slope ; updated.
2031    o fix the pickup behavior for obcs in combination with ptracers
2032    o fix a bug in ptracers_external_fields_load
2033    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
2034      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
2035    o transfered surface NH pressure to eta field (if exactConserv).
2036    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
2037         and update lab_sea output.txt file.
2038    o completing 3-dim. relaxation code: additional term
2039         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
2040      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
2041      * At compile time, in "EXF_OPTIONS.h" set
2042          #define  ALLOW_CLIMTEMP_RELAXATION
2043          #define  ALLOW_CLIMSALT_RELAXATION
2044      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
2045          tauThetaClimRelax3Dim = 15552000.0,
2046          tauSaltClimRelax3Dim  = 15552000.0,
2047      * 3 cases:
2048          1) Use a constant-in-time 3-dim. field
2049          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
2050          3) Real-time relax. to time-evolving prescribed field
2051    o Adding Laplacian-type smoothness constraint on
2052      initial and boundary (forcing) controls (ic, bc)
2053      * enable at compile-time via
2054        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
2055      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
2056      * Absolute scale somewhat unclear so far
2057      * no area weighting was included since no other cost term does so far
2058    
2059    checkpoint57y_post
2060    First step for a NLFS adjoint
2061    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
2062    o new init. routines for calc_r_star, calc_surf_dr
2063    o still need to deal with ini_masks_etc
2064    o testreport seemed happy
2065    checkpoint57y_pre
2066    
2067    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
2068    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
2069    o add new offset feature to offline pkg (plus minor cleanup)
2070    o cfc fixes for final year of integration
2071    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
2072      be in GCHEM_OPTIONS).
2073    
2074    checkpoint57x_post
2075    o fix testreport Pb in multiple test experiment.
2076    o cleanup our namelist syntax in verification:
2077      - make it more F95 standards compliant (some work still needed)
2078      - allows the vast majority of our tests to work with gfortran
2079    o Non-Hydrostatic:
2080     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
2081     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
2082    o Allow to apply AB on T,S rather than on AB(gT,gS):
2083     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
2084     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
2085       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
2086     - need a "clever" read_pickup to restart from the other AB formulation
2087    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
2088    o remove some unused variables (reduces number of compiler warnings)
2089    o adjoint
2090      * Disable useVariableViscosity for adjoint for time being
2091        (there are a number of extensive recomputations)
2092      * Initialize certain variables needed for adjoint
2093    
2094    checkpoint57w_post
2095    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
2096                 fix the singleCpuIO RS version of MDSWRITEFIELD
2097       and add a WARNING if using globalFiles=T with multi-processors.
2098    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
2099      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
2100    o tracer advection scheme:
2101      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
2102       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
2103       was not very convenient).
2104      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
2105       (further tests needed for the implicit DST & Flux-Limiter schemes).
2106    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
2107      and sRef for convenience, handy, when you want to initialize
2108      ptracers in a large domain with a constant non-zero value. Also,
2109      untangle ptracers_init.F a little.
2110    
2111    checkpoint57v_post
2112    o change dome exp. to use variable viscosity in side-drag terms.
2113    o remove all the files from the cfc_offline test since they are now
2114      incorporated into tutorial_cfc_offline which has been producing
2115      identical results for a few days of testing
2116    o add new parameter: sideDragFactor to enable half-slip-side BC
2117      and change side-drag S/R to use viscosity from mom_calc_visc
2118      (can switch back by setting sideDragFactor=0.); affects results at
2119      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
2120       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
2121    o vorticity & strain are now computed without masking, to account for
2122      no-slip-side BC in variable viscosity calculation ; mask is applied
2123      anyway later on, before computing advection/coriolis terms.
2124    o modify exp4 to test new obcs support for reading from external files
2125      and for passive tracers
2126    o fix behavior of ptracers_monitor when monitor output is written to a
2127      netcdf-file; still not independent of monitor.F (writes in the same
2128      file).
2129    o change default value of tRef (put a uniform, meaningful value for ocean
2130      & atmos) and initialize sRef (was missing, as Martin mentioned).
2131    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
2132      to be proportional to enstrophy dissipation length.  Thus,
2133       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
2134      This is now consistent with Smagorinsky and with the manual.
2135    
2136    checkpoint57u_post
2137    o OBCS and PTRACERS: add open boundary support for passive tracers
2138      - either use homogenous (pseudo) v.Neumann conditions or prescribe
2139        OB-values from file; this is not different from the way theta and salinity
2140        are treated
2141      - however, Orlanski-radiation conditions are not supported, and the model
2142        will stop if you use pTracers and Orlanski at the same time.
2143      - beefed up the rountine obcs_external_fields_load: now only those open
2144        boundary values are overwritten with values from files for which there
2145        are really files, otherwise the OB-fields remain untouched. This makes
2146        it possible to use different OBs at different ends of the domain (as
2147        with EXF)
2148    o reduce number of exch calls in shap_filt (s2).
2149    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
2150      truncation level) 4/5 MLAdjust test results (11&12 digits match).
2151    
2152    checkpoint57t_post
2153    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
2154    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
2155      same truncation, independent of the face number: affects affects several
2156      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
2157    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
2158      note that biharmonic viscosity + no-slip was not tested in any experiment.
2159    o fix bug in non-linear free-surf side-drag ; generate new output for
2160      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
2161    o make mnc honor the writeBinaryPrec flag for most kinds of output
2162    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
2163    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
2164      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
2165    o add brackets in multi-terms sum to get same truncation, independent of
2166      the face number (manage to get exactly same value of gU,gV at the cs-edge)
2167      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
2168    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
2169      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
2170      a maximum grid-scale Reynolds number.  Also, changes all length calculations
2171      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
2172      Suggested values of viscosity parameters found in mom_calc_visc.
2173      Many new viscosity diagnostics available.
2174    
2175    checkpoint57s_post
2176    o Add clearing-house for viscosity calculations, mom_calc_visc and
2177      correct numerous bugs in LeithD and Smagorinsky discretizations.  
2178      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
2179      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
2180      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
2181      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
2182      The Strain-Tension form is now called with useStrainTensonVisc=.true.
2183      ViscAhStrain and viscAhTension are now retired.
2184    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
2185    o In response to JMC's bug report, genmake2 now ignores any soft-links
2186      that it finds in the *current* directory when searching for files.
2187      Soft-links found in any other source directories will still work as
2188      they did before.
2189    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
2190      a C routine to unlimit the stack size
2191    o mnc-ify pkg/aim snapshot vars
2192    o mnc-ify pkg/land as requested by Daniel
2193    o various changes to mnc including:
2194      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
2195      - output can now be grouped so that all files within a group
2196          change the ITER portion of their names in lock-step together
2197      - can now read ("global") PER-FACE (in addition to PER-TILE) files
2198          and works with both EXCH1 and EXCH2 (but needs more testing)
2199      - writing works for all verification test cases w/ g77 on Linux
2200    
2201    checkpoint57r_post
2202    o make MNC variable initialization happen earlier
2203    o add diagnostics for (almost) each term of the momentum Eq.
2204    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
2205    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
2206    o remove MINIMAL_TAVE_OUTPUT option ;
2207      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
2208    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
2209      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
2210    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
2211    o add time-dependent SST, SSS control
2212    o cost terms in ecco/ modularized (new cost_generic.F)
2213    o cost_averages routines are modularized (new cost_averagesgeneric.F)
2214    o new infrastructure for seaice model vs. obs misfits in seaice/
2215      * driver from the_main_loop.F is seaice_cost_driver.F
2216      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
2217      * gradient check in Exp. 6a of natl_box_adjoint/
2218    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
2219      (see README file)
2220    
2221    checkpoint57q_post
2222    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
2223    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
2224      - bug was reported by Jean-Michel and Ian Fenty
2225    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
2226      update exp. cpl_aim+ocn output.
2227    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
2228      Needed for high-res. runs with large global files
2229      to be able to limit tapelev size
2230    o Changed some tests for adjoint:
2231      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
2232      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
2233      * global_ocean.90x40x15/ back to default 3-level checkpointing
2234    o Modifications to enable scripted COMMON to MODULE conversion
2235      * verification/OpenAD/code/ has necessary scripts and description;
2236      * converts, compiles and runs successfully;
2237    
2238    checkpoint57p_post
2239    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
2240    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
2241      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
2242    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
2243    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
2244      (was already the case for dissipation with mom_vecinv,
2245       and also the case for grad.PhiHyd when staggered-timeStep)
2246      This will allow to put dissipation out-off the AB time-stepping.
2247     Unfortunately, affects truncation error. Update output of exp. that "fails"
2248      (cg2d matching number) and leave the others for later: front_relax(10),
2249      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
2250      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
2251    
2252    checkpoint57o_post
2253    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
2254      (2) its ready to be documented during the 20050801 DocFest
2255    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
2256      for ideal_2D_oce and lab_sea on linux_ia32_g77
2257    o set to #undef CTRL_SET_OLD_MAXCVARS_30
2258      in global1x1_tot/code_seaice_adj to access indices 32, 33
2259      (worth another tag)
2260    
2261    checkpoint57n_post
2262    o adding precip control xx_precip 32
2263    o adding swflux control xx_swflux 33
2264    o Replacing 10 forcing penalty cost routines by 1 generic.
2265    o Implementing partitioning in time-mean and variable adjustment
2266      for atmos. state.
2267    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
2268    o in natl_box_adjoint:
2269      * updated exp 1 to 10
2270        (but does not have time-mean vs. variable split results yet)
2271    o updated global1x1/*_seaice_adj/
2272      to incorporate latest changes
2273    o enable useSingleCpuIO for mdsio vector routines
2274      (applies in particular to tapelev I/O)
2275    o removed inefficient K-loop in all active_file*control*.F
2276    
2277    checkpoint57m_post
2278    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
2279      and advect_cs (use EXCH-2 and standard cs-32 grid files).
2280    o pkg/exch2: filling of face-corner halo regions is optional
2281      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
2282    
2283    checkpoint57l_post
2284     tag before updating tutorials (pre-release-2)
2285    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
2286       for output and interpolation of input fields onto model grid)
2287    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
2288       Affects results of exp. rotating_tank ; update output.txt.
2289    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
2290          and taking the square quantity and/or using a fraction-weight field.
2291    o fix aim_diagnostics_init.F mate numbers.
2292    o add mnc output capability to diagnostics/diagstat and update
2293      our cvsignore files for the ACSII output generated
2294    
2295    checkpoint57k_post
2296    o lab_sea now uses diagnostics package and provides a suite of
2297      new EXF diagnostics output.
2298    
2299    checkpoint57j_post
2300    o exf
2301      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
2302        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
2303        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
2304      * extended diagnostics output
2305        - now includes all EXF variables
2306        - hs, hl moved to common block
2307        - separate S/R for diagnostics, called after ctrl vector is added
2308        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
2309        - EXFqnet contains true Qnet (i.e. includes qsw)
2310      * updated verif. lab_sea, global_with_exf
2311      * Rearranging hflux (exf_mapfields -> exf_getforcing)
2312        to ensure that diagnostics sees a true EXFqnet
2313    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
2314    o diagnostics pkg: change pointers so that 1 diagnostic can be used
2315      several times with different frequencies.
2316    o mnc-ify the thsice package as requested by Daniel Enderton
2317      - the monitor--MNC output needs work
2318      - many attributes need to be added (most are currently blank)
2319    o mnc-ify theaim_v23 package as requested by Daniel Enderton
2320      - many attributes need to be added (most are currently blank)
2321    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
2322    o add Sadourny like discretization to the 4th.O vorticity advection scheme
2323    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
2324      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
2325         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
2326    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
2327     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
2328    
2329    checkpoint57i_post
2330    o Diagnostics package was changed: diagnostic allocation is now deactivated
2331      by setting an empty file name in the namelist (used to be by setting 0 frequency)
2332    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
2333      add 1rst Order upwind vertical Shear.
2334    o add a quick fix for A/B checkpointing in OFFLINE mode
2335    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
2336      end-run around the C/Fortran linking horror in eesup/src/timers.F
2337    o added pkg/runclock: allows user to terminate run based on wall clock
2338    o added non-hydrostatic scaling parameter: nh_am2
2339    o pkg/my82: futile attempt to make results compiler-independent by adding
2340      some "_d 0", etc. no effect.
2341    o for mnc output, fill the 'T' coordinate var with myTime and create a
2342      separate 'iter' variable for iteration count
2343    o pkg/diagnostics:
2344      add new capability: output of Global/Regional & per-level statistics ;
2345      tested against monitor output (including land & thSIce) on various exp.
2346    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
2347    
2348    checkpoint57h_done
2349      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
2350      data.diagnostics, data.gchem, data.ptracers) is done.
2351    
2352    o pkg/diagnostics: prepare for Global/Regional statistics.
2353      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
2354    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
2355      and rename it: DIFFERENT_MULTIPLE
2356    
2357    checkpoint57h_post
2358    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
2359    o pkg/diagnostics: change output frequency, now in seconds (instead
2360      of Nb of iterations). This requires to change data.diagnostics.
2361    checkpoint57h_pre
2362    
2363    o in mnc, let the user create the output dir if both mnc_outdir_date
2364      and mnc_outdir_num are false
2365    o add fflags() to pkg/diagnostics which allows one to specify, on a
2366      per-file basis, the file precision [default behavior is unchanged]
2367    o added diagnostics to pkg/kpp, including computation of mixed layer
2368      depth based on a temperature/density criterion
2369    o updated verification/natl_box to test the new pkg/kpp diagnostics
2370    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
2371    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
2372    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
2373      not mnc -- this mistake was found by JMC and is now corrected
2374    
2375    checkpoint57g_post
2376    o add Adams-Bashforth 3rd Order time stepping:
2377      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
2378      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
2379    checkpoint57g_pre
2380    
2381    o make lambda[Theta,Salt]ClimRelax spatially varying
2382      (default remains spatially uniform constant based on tau)
2383    o added new control variables
2384      * init. uVel, vVel, etanN
2385      * lambda[Theta,Salt]ClimRelax
2386    o separate masks used for ctrl_pack/unpack 'from write_grid' output
2387      (suggested by G. Forget)
2388    
2389    checkpoint57f_post
2390    o add parameter "baseTime" = model base time = time at iteration zero
2391      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
2392      account for baseTime shift
2393    o move Coriolis arrays from PARAMS.h to GRID.h
2394    checkpoint57f_pre
2395    
2396    o mnc-ifying the seaice package
2397    o introduced an alternative length scale calculation for use in the limiting
2398      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
2399    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
2400    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
2401      as well as grad(vort3).  Made it compatible with both approximate form
2402      for the cubed sphere and full form of these gradients.  Added flag
2403      useFullLeith to select between approximate and full form.  
2404    o add "d0" in getcon.F to reduce differences between compilers/platforms
2405      update output.txt of exp. fizhi-gridalt-hs
2406    o change port_rand funtion to allow to set the seed.
2407    o fix obscure MNC bug involving conversion between reals and integers
2408      - it caused no problems with certain (eg. gcc, ifc) compilers but the
2409        new version is now more standards-compliant
2410    o adjoint-related modifications
2411      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
2412      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
2413      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
2414    
2415    checkpoint57e_post
2416    o Adding eddy stress controls a la Ferreira et al.
2417    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
2418
