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