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

324    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
325      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
326        this flag is now only visible within GCHEM-pkg routines.
327      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
328        be replaced by a 3D array that is computed before thermodynamics; for
329        this, the tracer ID iTracer had to be included into the parameter list
330        of ptracers_forcing
331      - set up forward_step to call gchem_forcing, that will replace
332        gchem_forcing_int in ptracers_forcing
333      - cleaning up
