5      ==============================      ==============================
6    
7    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
8      (2) its ready to be documented during the 20050801 DocFest
9    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
10      for ideal_2D_oce and lab_sea on linux_ia32_g77
11    
12    checkpoint57n_post
13    o adding precip control xx_precip 32

15    o Replacing 10 forcing penalty cost routines by 1 generic.
16    o Implementing partitioning in time-mean and variable adjustment
17      for atmos. state.
18    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
19    o in natl_box_adjoint:
20      * updated exp 1 to 10
21        (but does not have time-mean vs. variable split results yet)
22    o updated global1x1/*_seaice_adj/
23      to incorporate latest changes
24    o enable useSingleCpuIO for mdsio vector routines
25      (applies in particular to tapelev I/O)

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

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