5      ==============================      ==============================
6    
7    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
8    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
9      - bug was reported by Jean-Michel and Ian Fenty
10    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
11      update exp. cpl_aim+ocn output.
12    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
13      Needed for high-res. runs with large global files
14      to be able to limit tapelev size
15    o Changed some tests for adjoint:
16      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
17      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
18      * global_ocean.90x40x15/ back to default 3-level checkpointing
19    
20    checkpoint57p_post
21    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
22    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
23      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
24    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
25    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
26      (was already the case for dissipation with mom_vecinv,
27       and also the case for grad.PhiHyd when staggered-timeStep)
28      This will allow to put dissipation out-off the AB time-stepping.
29     Unfortunately, affects truncation error. Update output of exp. that "fails"
30      (cg2d matching number) and leave the others for later: front_relax(10),
31      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
32      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
33    
34    checkpoint57o_post
35    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
36      (2) its ready to be documented during the 20050801 DocFest
37    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
38      for ideal_2D_oce and lab_sea on linux_ia32_g77
39    o set to #undef CTRL_SET_OLD_MAXCVARS_30
40      in global1x1_tot/code_seaice_adj to access indices 32, 33
41      (worth another tag)
42    
43    checkpoint57n_post
44    o adding precip control xx_precip 32
45    o adding swflux control xx_swflux 33
46    o Replacing 10 forcing penalty cost routines by 1 generic.
47    o Implementing partitioning in time-mean and variable adjustment
48      for atmos. state.
49    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
50    o in natl_box_adjoint:
51      * updated exp 1 to 10
52        (but does not have time-mean vs. variable split results yet)
53    o updated global1x1/*_seaice_adj/
54      to incorporate latest changes
55    o enable useSingleCpuIO for mdsio vector routines
56      (applies in particular to tapelev I/O)
57    o removed inefficient K-loop in all active_file*control*.F
58    
59    checkpoint57m_post
60    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
61      and advect_cs (use EXCH-2 and standard cs-32 grid files).
62    o pkg/exch2: filling of face-corner halo regions is optional
63      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
64    
65    checkpoint57l_post
66     tag before updating tutorials (pre-release-2)
67    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
68       for output and interpolation of input fields onto model grid)
69    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
70       Affects results of exp. rotating_tank ; update output.txt.
71    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
72          and taking the square quantity and/or using a fraction-weight field.
73    o fix aim_diagnostics_init.F mate numbers.
74    o add mnc output capability to diagnostics/diagstat and update
75      our cvsignore files for the ACSII output generated
76    
77    checkpoint57k_post
78    o lab_sea now uses diagnostics package and provides a suite of
79      new EXF diagnostics output.
80    
81    checkpoint57j_post
82    o exf
83      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
84        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
85        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
86      * extended diagnostics output
87        - now includes all EXF variables
88        - hs, hl moved to common block
89        - separate S/R for diagnostics, called after ctrl vector is added
90        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
91        - EXFqnet contains true Qnet (i.e. includes qsw)
92      * updated verif. lab_sea, global_with_exf
93      * Rearranging hflux (exf_mapfields -> exf_getforcing)
94        to ensure that diagnostics sees a true EXFqnet
95    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
96    o diagnostics pkg: change pointers so that 1 diagnostic can be used
97      several times with different frequencies.
98    o mnc-ify the thsice package as requested by Daniel Enderton
99      - the monitor--MNC output needs work
100      - many attributes need to be added (most are currently blank)
101    o mnc-ify theaim_v23 package as requested by Daniel Enderton
102      - many attributes need to be added (most are currently blank)
103    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
104    o add Sadourny like discretization to the 4th.O vorticity advection scheme
105    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
106      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
107         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
108    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
109     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
110    
111    checkpoint57i_post
112    o Diagnostics package was changed: diagnostic allocation is now deactivated
113      by setting an empty file name in the namelist (used to be by setting 0 frequency)
114    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
115      add 1rst Order upwind vertical Shear.
116    o add a quick fix for A/B checkpointing in OFFLINE mode
117    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
118      end-run around the C/Fortran linking horror in eesup/src/timers.F
119    o added pkg/runclock: allows user to terminate run based on wall clock
120    o added non-hydrostatic scaling parameter: nh_am2
121    o pkg/my82: futile attempt to make results compiler-independent by adding
122      some "_d 0", etc. no effect.
123    o for mnc output, fill the 'T' coordinate var with myTime and create a
124      separate 'iter' variable for iteration count
125    o pkg/diagnostics:
126      add new capability: output of Global/Regional & per-level statistics ;
127      tested against monitor output (including land & thSIce) on various exp.
128    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
129    
130    checkpoint57h_done
131      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
132      data.diagnostics, data.gchem, data.ptracers) is done.
133    
134    o pkg/diagnostics: prepare for Global/Regional statistics.
135      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
136    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
137      and rename it: DIFFERENT_MULTIPLE
138    
139    checkpoint57h_post
140    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
141    o pkg/diagnostics: change output frequency, now in seconds (instead
142      of Nb of iterations). This requires to change data.diagnostics.
143    checkpoint57h_pre
144    
145    o in mnc, let the user create the output dir if both mnc_outdir_date
146      and mnc_outdir_num are false
147    o add fflags() to pkg/diagnostics which allows one to specify, on a
148      per-file basis, the file precision [default behavior is unchanged]
149    o added diagnostics to pkg/kpp, including computation of mixed layer
150      depth based on a temperature/density criterion
151    o updated verification/natl_box to test the new pkg/kpp diagnostics
152    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
153    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
154    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
155      not mnc -- this mistake was found by JMC and is now corrected
156    
157    checkpoint57g_post
158    o add Adams-Bashforth 3rd Order time stepping:
159      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
160      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
161    checkpoint57g_pre
162    
163    o make lambda[Theta,Salt]ClimRelax spatially varying
164      (default remains spatially uniform constant based on tau)
165    o added new control variables
166      * init. uVel, vVel, etanN
167      * lambda[Theta,Salt]ClimRelax
168    o separate masks used for ctrl_pack/unpack 'from write_grid' output
169      (suggested by G. Forget)
170    
171    checkpoint57f_post
172    o add parameter "baseTime" = model base time = time at iteration zero
173      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
174      account for baseTime shift
175    o move Coriolis arrays from PARAMS.h to GRID.h
176    checkpoint57f_pre
177    
178    o mnc-ifying the seaice package
179    o introduced an alternative length scale calculation for use in the limiting
180      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
181    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
182    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
183      as well as grad(vort3).  Made it compatible with both approximate form
184      for the cubed sphere and full form of these gradients.  Added flag
185      useFullLeith to select between approximate and full form.  
186    o add "d0" in getcon.F to reduce differences between compilers/platforms
187      update output.txt of exp. fizhi-gridalt-hs
188    o change port_rand funtion to allow to set the seed.
189    o fix obscure MNC bug involving conversion between reals and integers
190      - it caused no problems with certain (eg. gcc, ifc) compilers but the
191        new version is now more standards-compliant
192    o adjoint-related modifications
193      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
194      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
195      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
196    
197    checkpoint57e_post
198    o Adding eddy stress controls a la Ferreira et al.
199    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
200    
201    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
202      update output.txt of exp. fizhi-gridalt-hs
203    o add more "Z" dimensions and associated coordinate vars to MNC
204    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
205    o parameter calendarDumps: when set, approximate months (30-31 days) and years
206      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
207      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
208      months and years.  Requires pkg/cal.
209    o diagnostics: add pickup functionality
210      - off by default for backwards compatibility
211      - current version only uses MDSIO -- MNC will be added
212    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
213    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
214    
215    checkpoint57d_post
216    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
217    o modify verification/ideal_2D_oce so that it tests the creation of mnc
218      output from the diagnostics package
219    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
220    o make genmake2 more portable by using ".$FS" instead of ".f" for more
221      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
222    o add coordinate variables to the MNC output from the diagnostics package
223    o change MNC-flags default value: true when useMNC=TRUE
224    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
225      the ability (off by default) to read the grid information using MNC
226    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
227    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
228    o do snap-shot diagnostics at the middle of the time-interval (instead of
229      at the end).
230    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
231      new test for AIM with thSIce + slab-ocean
232    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
233    o move state variable diagnostics to the beginning of the time step ;
234      (note: still needs some work specially for snap-shot diagnostics)
235      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
236    
237    checkpoint57c_post
238    o Change testing option (-ieee) to get closer agreement between g77 & ifort
239    o generate new output.txt files on faulks with g77 & the new -ieee option
240    checkpoint57c_pre
241    
242    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
243      update output.txt of exp. global_ocean.90x40x15
244    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
245      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
246    o add saltFlux(+File) forcing capability with periodicExternalForcing
247    o allow to use pkg diagnostics for GM-Redi & ThSIce output
248    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
249    o improvements for the MNC output from DIAGNOSTICS:
250      - correct handling of the unlimitied dimension
251      - all dims now have associated coordinate variables
252      - variables located at U, V, and Corner ("Z") points are now written
253        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
254        *all* data points are output
255    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
256    o added pkg/seaice/seaice_monitor.F
257    o mdsio_readfield.F can now read files visible only to master MPI process.
258    o pkg/seaice: some test code for ice-modified ocean stress
259    o exf_getffields interpolation defaults to bilinear for all scalar forcing
260      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
261      spurious negative numbers for precipitation and humidity.  Will cause
262      some small numerical differences for integrations using pkg/exf/exf_interp.F.
263    o pkg/ctrl/
264      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
265        May be enabled via doPackDiag
266      *  introduce z-scaling of
267         + gradient (doZscalePack) and
268         + control (doZscaleUnpack)
269    o pkg/mdsio/
270      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
271      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
272    
273    checkpoint57b_post
274    o simplify options in diagnostics_fill arguments (remove weird combinations)
275    o fix MNC coordinate variables so that they now contain per-face index
276      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
277      general, EXCH2 grids are only aligned to a "local" coordinate system
278    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
279    o Implement instantaneous output within pkg diagnostics:
280      setting a negative frequency in data.diagnostics produces
281     "snap-shot" output (as opposed to time-average if freq > 0)
282    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
283      NOTE: change ptracer diagnostics name: use 2 characters to work with
284            more than 9 tracers. Add also diagnostics of advect & diffus flux.
285    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
286      becomes the coordinate variable for the 'T' dimension
287    o add CF-style coordinate variables to MNC
288      - just a first cut:  numbers are meaningless on the cubesphere and
289        missing along the T axis but otherwise it works!
290    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
291    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
292    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
293      this is based directly on what the model compute, so that the content of
294      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
295    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
296    o clean up build options files for SunOS, in particular
297      - remove -traditional from xmakedepend
298      - change -xarch=v9 to -xarch=native for f77
299      - restore use of make (not gmake)
300      - add CC=gcc if using g77
301    o changes per discussion of AM, JMC, & EH3 today:
302      - move redundant "grid" variables out of "state" -- in preparation of
303        creating proper CF-style coordinate variables and in recognition
304        that any/all grid variables can be easily copied (eg. w/NCO) from
305        the grid files into any of the other NetCDF files
306      - *always* output grid variables with MDSIO (this will eventually be
307        changed)
308      - output MNC grid file if useMNC is true
309    o every instance of _END_MASTER() has been found and replaced with
310      _END_MASTER( myThid ) in order to satisfy certain picky Sun
311      preprocessors
312    o re-arrange diagnostics pkg initialisation:
313     - allow each package to extend the available diagnostics list
314     - add some checking and fix small problems (multi-threaded, ...)
315     - new S/R diagnostics_fill (replace fill_diagnostics):
316       look through the short list of active diag. (instead of the long list)
317       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
318    
319    checkpoint57a_post
320    o this set of changes restores TAMC compatibility
321      tested for global_ocean.90x40x15 adjoint on trough
322      (what a pain)
323    
324    checkpoint57a_pre
325    o some modifs in tools/build_options for sunos
326    o call ctrl_pack for ctrl at end for optimcycle=0
327    
328    checkpoint57
329    o add horizontal bi-harmonic viscosity for vertical velocity
330      - new parameter viscA4W (defaults to viscA4)
331      - affects only non-hydrostatic code
332      - to be done: no-slip lateral boundary conditions
333    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
334    o implement Implicit Vertical advection for pTracers
335    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
336      (implemented also for implicit vertical diffusion & advection)
337    o OBCS: extend application of tracer open boundary conditions
338      to a strip beyond the boundary of width Olx/Oly
339    o add call monitor to TAF set of required calls (flow directives)
340      and include in natl_box_adjoint
341    o untangle a few ifdefs related to cost, ctrl, autodiff
342      untangel a few ALLOW_ECCO_OPTIMIZATION
343    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
344      (theta2, salt2 in ecco_cost_weights)
345    
346    checkpoint56c_post
347    o OBCS as control variables
348      - update ctrl_ad_diff.list, obcs_ad_diff.list
349      - remove balance of obcs controls from default
350      - fix index bug nobcs in ctrl_init
351      - fix dummy fields filen in ctrl_pack
352      - add dummy weights for obcs
353    o lsopt: comment out fort.94 output
354    o optim:
355      - remove unnecessary header files
356      - adjusted namelists
357      - add xerbla.F to Makefile
358    o exf:
359      - multiple modifications of exf_check_range
360      - unit change in exf_init_runoff from [m/year] to [m/s]
361    o mdsio:
362      - i/o-vector change debugLevel from debLevA to debLevB
363    
364    checkpoint56b_post
365    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
366      is called from DO_THE_MODEL_IO
367      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
368      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
369      - clean up PTRACERS_WRITE_TIMEAVE a little
370    o add another verification experiment that tests both the cfc-pkg and
371      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
372      reactive tendencies treated inline with regular timestepping
373    o testreport previously did a lousy job of comparing small numbers, so
374      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
375      implemented in the little c-progam tmp_cmpnum.c which is embedded in
376      testreport.
377    o ptracers_monitor: bug fix for MPI
378    
379    checkpoint56a_post
380    o GCHEM: finish reorganizating the package
381      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
382        (introduces another 3D-array for each passive tracer, but only if
383        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
384        gchemTendency is not needed because the timestep is done separately)
385      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
386      - GCHEM is now---more or less cleanly---separate from PTRACERS
387      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
388        so clear to me how that should be done in a general way.
389    o CFC: improve formatting of output in CFC_ATMOS
390    o PTRACERS:
391      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
392        that ALL experiments with ptracers enable can be checked. This makes
393        GCHEM_MONITOR obsolete.
394      - include a runtime parameter PTRACERS_monitorFreq that defaults to
395        monitorFreq
396      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
397    o add PTRACERS (PTR0[1-5]) to testreport output
398    o exf_check_range:
399      * default changed to .TRUE.
400      * will check values for niter0 if debLevA, every timestep if debLevB
401      * STOP in exf_check_range if 'out of range'
402      * range chosen generous to allow for potential extema
403      TBD: a version with stricter range
404           permitted range would be runtime parameters
405  o GMredi:  o GMredi:
406    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
407    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.

414        this flag is now only visible within GCHEM-pkg routines.
415      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
416        be replaced by a 3D array that is computed before thermodynamics; for
417        this, the tracer ID iTracer had to be included into the parameter list
418        of ptracers_forcing
419      - set up forward_step to call gchem_forcing, that will replace
420        gchem_forcing_int in ptracers_forcing
