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

380      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
381        this flag is now only visible within GCHEM-pkg routines.
382      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
383        be replaced by a 3D array that is computed before thermodynamics; for
384        this, the tracer ID iTracer had to be included into the parameter list
385        of ptracers_forcing
386      - set up forward_step to call gchem_forcing, that will replace
387        gchem_forcing_int in ptracers_forcing
