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

400      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
401        this flag is now only visible within GCHEM-pkg routines.
402      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
403        be replaced by a 3D array that is computed before thermodynamics; for
404        this, the tracer ID iTracer had to be included into the parameter list
405        of ptracers_forcing
406      - set up forward_step to call gchem_forcing, that will replace
407        gchem_forcing_int in ptracers_forcing
408      - cleaning up
409  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
