5      ==============================      ==============================
6    
7    o adding precip control xx_precip
8    o moved ptracer ctrl index 17 -> 32
9    o in natl_box_adjoint:
10      * updated: results_bulk/

15    
16    checkpoint57m_post
17    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
18      and advect_cs (use EXCH-2 and standard cs-32 grid files).
19    o pkg/exch2: filling of face-corner halo regions is optional
20      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
21    
22    checkpoint57l_post
23     tag before updating tutorials (pre-release-2)
24    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
25       for output and interpolation of input fields onto model grid)
26    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
27       Affects results of exp. rotating_tank ; update output.txt.
28    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
29          and taking the square quantity and/or using a fraction-weight field.
30    o fix aim_diagnostics_init.F mate numbers.
31    o add mnc output capability to diagnostics/diagstat and update
32      our cvsignore files for the ACSII output generated
33    
34    checkpoint57k_post
35    o lab_sea now uses diagnostics package and provides a suite of
36      new EXF diagnostics output.
37    
38    checkpoint57j_post
39    o exf
40      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
41        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
42        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
43      * extended diagnostics output
44        - now includes all EXF variables
45        - hs, hl moved to common block
46        - separate S/R for diagnostics, called after ctrl vector is added
47        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
48        - EXFqnet contains true Qnet (i.e. includes qsw)
49      * updated verif. lab_sea, global_with_exf
50      * Rearranging hflux (exf_mapfields -> exf_getforcing)
51        to ensure that diagnostics sees a true EXFqnet
52    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
53    o diagnostics pkg: change pointers so that 1 diagnostic can be used
54      several times with different frequencies.
55    o mnc-ify the thsice package as requested by Daniel Enderton
56      - the monitor--MNC output needs work
57      - many attributes need to be added (most are currently blank)
58    o mnc-ify theaim_v23 package as requested by Daniel Enderton
59      - many attributes need to be added (most are currently blank)
60    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
61    o add Sadourny like discretization to the 4th.O vorticity advection scheme
62    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
63      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
64         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
65    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
66     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
67    
68    checkpoint57i_post
69    o Diagnostics package was changed: diagnostic allocation is now deactivated
70      by setting an empty file name in the namelist (used to be by setting 0 frequency)
71    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
72      add 1rst Order upwind vertical Shear.
73    o add a quick fix for A/B checkpointing in OFFLINE mode
74    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
75      end-run around the C/Fortran linking horror in eesup/src/timers.F
76    o added pkg/runclock: allows user to terminate run based on wall clock
77    o added non-hydrostatic scaling parameter: nh_am2
78    o pkg/my82: futile attempt to make results compiler-independent by adding
79      some "_d 0", etc. no effect.
80    o for mnc output, fill the 'T' coordinate var with myTime and create a
81      separate 'iter' variable for iteration count
82    o pkg/diagnostics:
83      add new capability: output of Global/Regional & per-level statistics ;
84      tested against monitor output (including land & thSIce) on various exp.
85    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
86    
87    checkpoint57h_done
88      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
89      data.diagnostics, data.gchem, data.ptracers) is done.
90    
91    o pkg/diagnostics: prepare for Global/Regional statistics.
92      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
93    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
94      and rename it: DIFFERENT_MULTIPLE
95    
96    checkpoint57h_post
97    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
98    o pkg/diagnostics: change output frequency, now in seconds (instead
99      of Nb of iterations). This requires to change data.diagnostics.
100    checkpoint57h_pre
101    
102    o in mnc, let the user create the output dir if both mnc_outdir_date
103      and mnc_outdir_num are false
104    o add fflags() to pkg/diagnostics which allows one to specify, on a
105      per-file basis, the file precision [default behavior is unchanged]
106    o added diagnostics to pkg/kpp, including computation of mixed layer
107      depth based on a temperature/density criterion
108    o updated verification/natl_box to test the new pkg/kpp diagnostics
109    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
110    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
111    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
112      not mnc -- this mistake was found by JMC and is now corrected
113    
114    checkpoint57g_post
115    o add Adams-Bashforth 3rd Order time stepping:
116      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
117      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
118    checkpoint57g_pre
119    
120    o make lambda[Theta,Salt]ClimRelax spatially varying
121      (default remains spatially uniform constant based on tau)
122    o added new control variables
123      * init. uVel, vVel, etanN
124      * lambda[Theta,Salt]ClimRelax
125    o separate masks used for ctrl_pack/unpack 'from write_grid' output
126      (suggested by G. Forget)
127    
128    checkpoint57f_post
129    o add parameter "baseTime" = model base time = time at iteration zero
130      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
131      account for baseTime shift
132    o move Coriolis arrays from PARAMS.h to GRID.h
133    checkpoint57f_pre
134    
135    o mnc-ifying the seaice package
136    o introduced an alternative length scale calculation for use in the limiting
137      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
138    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
139    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
140      as well as grad(vort3).  Made it compatible with both approximate form
141      for the cubed sphere and full form of these gradients.  Added flag
142      useFullLeith to select between approximate and full form.  
143    o add "d0" in getcon.F to reduce differences between compilers/platforms
144      update output.txt of exp. fizhi-gridalt-hs
145    o change port_rand funtion to allow to set the seed.
146    o fix obscure MNC bug involving conversion between reals and integers
147      - it caused no problems with certain (eg. gcc, ifc) compilers but the
148        new version is now more standards-compliant
149    o adjoint-related modifications
150      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
151      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
152      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
153    
154    checkpoint57e_post
155    o Adding eddy stress controls a la Ferreira et al.
156    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
157    
158    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
159      update output.txt of exp. fizhi-gridalt-hs
160    o add more "Z" dimensions and associated coordinate vars to MNC
161    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
162    o parameter calendarDumps: when set, approximate months (30-31 days) and years
163      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
164      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
165      months and years.  Requires pkg/cal.
166    o diagnostics: add pickup functionality
167      - off by default for backwards compatibility
168      - current version only uses MDSIO -- MNC will be added
169    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
170    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
171    
172    checkpoint57d_post
173    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
174    o modify verification/ideal_2D_oce so that it tests the creation of mnc
175      output from the diagnostics package
176    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
177    o make genmake2 more portable by using ".$FS" instead of ".f" for more
178      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
179    o add coordinate variables to the MNC output from the diagnostics package
180    o change MNC-flags default value: true when useMNC=TRUE
181    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
182      the ability (off by default) to read the grid information using MNC
183    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
184    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
185    o do snap-shot diagnostics at the middle of the time-interval (instead of
186      at the end).
187    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
188      new test for AIM with thSIce + slab-ocean
189    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
190    o move state variable diagnostics to the beginning of the time step ;
191      (note: still needs some work specially for snap-shot diagnostics)
192      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
193    
194    checkpoint57c_post
195    o Change testing option (-ieee) to get closer agreement between g77 & ifort
196    o generate new output.txt files on faulks with g77 & the new -ieee option
197    checkpoint57c_pre
198    
199    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
200      update output.txt of exp. global_ocean.90x40x15
201    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
202      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
203    o add saltFlux(+File) forcing capability with periodicExternalForcing
204    o allow to use pkg diagnostics for GM-Redi & ThSIce output
205    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
206    o improvements for the MNC output from DIAGNOSTICS:
207      - correct handling of the unlimitied dimension
208      - all dims now have associated coordinate variables
209      - variables located at U, V, and Corner ("Z") points are now written
210        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
211        *all* data points are output
212    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
213    o added pkg/seaice/seaice_monitor.F
214    o mdsio_readfield.F can now read files visible only to master MPI process.
215    o pkg/seaice: some test code for ice-modified ocean stress
216    o exf_getffields interpolation defaults to bilinear for all scalar forcing
217      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
218      spurious negative numbers for precipitation and humidity.  Will cause
219      some small numerical differences for integrations using pkg/exf/exf_interp.F.
220    o pkg/ctrl/
221      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
222        May be enabled via doPackDiag
223      *  introduce z-scaling of
224         + gradient (doZscalePack) and
225         + control (doZscaleUnpack)
226    o pkg/mdsio/
227      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
228      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
229    
230    checkpoint57b_post
231    o simplify options in diagnostics_fill arguments (remove weird combinations)
232    o fix MNC coordinate variables so that they now contain per-face index
233      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
234      general, EXCH2 grids are only aligned to a "local" coordinate system
235    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
236    o Implement instantaneous output within pkg diagnostics:
237      setting a negative frequency in data.diagnostics produces
238     "snap-shot" output (as opposed to time-average if freq > 0)
239    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
240      NOTE: change ptracer diagnostics name: use 2 characters to work with
241            more than 9 tracers. Add also diagnostics of advect & diffus flux.
242    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
243      becomes the coordinate variable for the 'T' dimension
244    o add CF-style coordinate variables to MNC
245      - just a first cut:  numbers are meaningless on the cubesphere and
246        missing along the T axis but otherwise it works!
247    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
248    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
249    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
250      this is based directly on what the model compute, so that the content of
251      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
252    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
253    o clean up build options files for SunOS, in particular
254      - remove -traditional from xmakedepend
255      - change -xarch=v9 to -xarch=native for f77
256      - restore use of make (not gmake)
257      - add CC=gcc if using g77
258    o changes per discussion of AM, JMC, & EH3 today:
259      - move redundant "grid" variables out of "state" -- in preparation of
260        creating proper CF-style coordinate variables and in recognition
261        that any/all grid variables can be easily copied (eg. w/NCO) from
262        the grid files into any of the other NetCDF files
263      - *always* output grid variables with MDSIO (this will eventually be
264        changed)
265      - output MNC grid file if useMNC is true
266    o every instance of _END_MASTER() has been found and replaced with
267      _END_MASTER( myThid ) in order to satisfy certain picky Sun
268      preprocessors
269    o re-arrange diagnostics pkg initialisation:
270     - allow each package to extend the available diagnostics list
271     - add some checking and fix small problems (multi-threaded, ...)
272     - new S/R diagnostics_fill (replace fill_diagnostics):
273       look through the short list of active diag. (instead of the long list)
274       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
275    
276    checkpoint57a_post
277    o this set of changes restores TAMC compatibility
278      tested for global_ocean.90x40x15 adjoint on trough
279      (what a pain)
280    
281    checkpoint57a_pre
282    o some modifs in tools/build_options for sunos
283    o call ctrl_pack for ctrl at end for optimcycle=0
284    
285    checkpoint57
286    o add horizontal bi-harmonic viscosity for vertical velocity
287      - new parameter viscA4W (defaults to viscA4)
288      - affects only non-hydrostatic code
289      - to be done: no-slip lateral boundary conditions
290    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
291    o implement Implicit Vertical advection for pTracers
292    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
293      (implemented also for implicit vertical diffusion & advection)
294    o OBCS: extend application of tracer open boundary conditions
295      to a strip beyond the boundary of width Olx/Oly
296    o add call monitor to TAF set of required calls (flow directives)
297      and include in natl_box_adjoint
298    o untangle a few ifdefs related to cost, ctrl, autodiff
299      untangel a few ALLOW_ECCO_OPTIMIZATION
300    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
301      (theta2, salt2 in ecco_cost_weights)
302    
303    checkpoint56c_post
304    o OBCS as control variables
305      - update ctrl_ad_diff.list, obcs_ad_diff.list
306      - remove balance of obcs controls from default
307      - fix index bug nobcs in ctrl_init
308      - fix dummy fields filen in ctrl_pack
309      - add dummy weights for obcs
310    o lsopt: comment out fort.94 output
311    o optim:
312      - remove unnecessary header files
313      - adjusted namelists
314      - add xerbla.F to Makefile
315    o exf:
316      - multiple modifications of exf_check_range
317      - unit change in exf_init_runoff from [m/year] to [m/s]
318    o mdsio:
319      - i/o-vector change debugLevel from debLevA to debLevB
320    
321    checkpoint56b_post
322    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
323      is called from DO_THE_MODEL_IO
324      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
325      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
326      - clean up PTRACERS_WRITE_TIMEAVE a little
327    o add another verification experiment that tests both the cfc-pkg and
328      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
329      reactive tendencies treated inline with regular timestepping
330    o testreport previously did a lousy job of comparing small numbers, so
331      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
332      implemented in the little c-progam tmp_cmpnum.c which is embedded in
333      testreport.
334    o ptracers_monitor: bug fix for MPI
335    
336    checkpoint56a_post
337    o GCHEM: finish reorganizating the package
338      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
339        (introduces another 3D-array for each passive tracer, but only if
340        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
341        gchemTendency is not needed because the timestep is done separately)
342      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
343      - GCHEM is now---more or less cleanly---separate from PTRACERS
344      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
345        so clear to me how that should be done in a general way.
346    o CFC: improve formatting of output in CFC_ATMOS
347    o PTRACERS:
348      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
349        that ALL experiments with ptracers enable can be checked. This makes
350        GCHEM_MONITOR obsolete.
351      - include a runtime parameter PTRACERS_monitorFreq that defaults to
352        monitorFreq
353      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
354    o add PTRACERS (PTR0[1-5]) to testreport output
355    o exf_check_range:
356      * default changed to .TRUE.
357      * will check values for niter0 if debLevA, every timestep if debLevB
358      * STOP in exf_check_range if 'out of range'
359      * range chosen generous to allow for potential extema
360      TBD: a version with stricter range
361           permitted range would be runtime parameters
362  o GMredi:  o GMredi:
363    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
364    - 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 367  o GCHEM:
367    - 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
368      the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP      the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
369    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
370      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
371        this flag is now only visible within GCHEM-pkg routines.
372      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
