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