5      ==============================      ==============================
6    
7    o adding precip control xx_precip 32
8    o adding swflux control xx_swflux 33
9    o in natl_box_adjoint:
10      * updated exp 1 to 10
11    o enable useSingleCpuIO for mdsio vector routines
12      (applies in particular to tapelev I/O)
13    o removed inefficient K-loop in all active_file*control*.F
14    
15    checkpoint57m_post
16    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
17      and advect_cs (use EXCH-2 and standard cs-32 grid files).
18    o pkg/exch2: filling of face-corner halo regions is optional
19      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
20    
21    checkpoint57l_post
22     tag before updating tutorials (pre-release-2)
23    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
24       for output and interpolation of input fields onto model grid)
25    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
26       Affects results of exp. rotating_tank ; update output.txt.
27    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
28          and taking the square quantity and/or using a fraction-weight field.
29    o fix aim_diagnostics_init.F mate numbers.
30    o add mnc output capability to diagnostics/diagstat and update
31      our cvsignore files for the ACSII output generated
32    
33    checkpoint57k_post
34    o lab_sea now uses diagnostics package and provides a suite of
35      new EXF diagnostics output.
36    
37    checkpoint57j_post
38    o exf
39      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
40        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
41        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
42      * extended diagnostics output
43        - now includes all EXF variables
44        - hs, hl moved to common block
45        - separate S/R for diagnostics, called after ctrl vector is added
46        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
47        - EXFqnet contains true Qnet (i.e. includes qsw)
48      * updated verif. lab_sea, global_with_exf
49      * Rearranging hflux (exf_mapfields -> exf_getforcing)
50        to ensure that diagnostics sees a true EXFqnet
51    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
52    o diagnostics pkg: change pointers so that 1 diagnostic can be used
53      several times with different frequencies.
54    o mnc-ify the thsice package as requested by Daniel Enderton
55      - the monitor--MNC output needs work
56      - many attributes need to be added (most are currently blank)
57    o mnc-ify theaim_v23 package as requested by Daniel Enderton
58      - many attributes need to be added (most are currently blank)
59    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
60    o add Sadourny like discretization to the 4th.O vorticity advection scheme
61    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
62      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
63         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
64    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
65     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
66    
67    checkpoint57i_post
68    o Diagnostics package was changed: diagnostic allocation is now deactivated
69      by setting an empty file name in the namelist (used to be by setting 0 frequency)
70    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
71      add 1rst Order upwind vertical Shear.
72    o add a quick fix for A/B checkpointing in OFFLINE mode
73    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
74      end-run around the C/Fortran linking horror in eesup/src/timers.F
75    o added pkg/runclock: allows user to terminate run based on wall clock
76    o added non-hydrostatic scaling parameter: nh_am2
77    o pkg/my82: futile attempt to make results compiler-independent by adding
78      some "_d 0", etc. no effect.
79    o for mnc output, fill the 'T' coordinate var with myTime and create a
80      separate 'iter' variable for iteration count
81    o pkg/diagnostics:
82      add new capability: output of Global/Regional & per-level statistics ;
83      tested against monitor output (including land & thSIce) on various exp.
84    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
85    
86    checkpoint57h_done
87      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
88      data.diagnostics, data.gchem, data.ptracers) is done.
89    
90    o pkg/diagnostics: prepare for Global/Regional statistics.
91      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
92    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
93      and rename it: DIFFERENT_MULTIPLE
94    
95    checkpoint57h_post
96    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
97    o pkg/diagnostics: change output frequency, now in seconds (instead
98      of Nb of iterations). This requires to change data.diagnostics.
99    checkpoint57h_pre
100    
101    o in mnc, let the user create the output dir if both mnc_outdir_date
102      and mnc_outdir_num are false
103    o add fflags() to pkg/diagnostics which allows one to specify, on a
104      per-file basis, the file precision [default behavior is unchanged]
105    o added diagnostics to pkg/kpp, including computation of mixed layer
106      depth based on a temperature/density criterion
107    o updated verification/natl_box to test the new pkg/kpp diagnostics
108    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
109    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
110    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
111      not mnc -- this mistake was found by JMC and is now corrected
112    
113    checkpoint57g_post
114    o add Adams-Bashforth 3rd Order time stepping:
115      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
116      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
117    checkpoint57g_pre
118    
119    o make lambda[Theta,Salt]ClimRelax spatially varying
120      (default remains spatially uniform constant based on tau)
121    o added new control variables
122      * init. uVel, vVel, etanN
123      * lambda[Theta,Salt]ClimRelax
124    o separate masks used for ctrl_pack/unpack 'from write_grid' output
125      (suggested by G. Forget)
126    
127    checkpoint57f_post
128    o add parameter "baseTime" = model base time = time at iteration zero
129      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
130      account for baseTime shift
131    o move Coriolis arrays from PARAMS.h to GRID.h
132    checkpoint57f_pre
133    
134    o mnc-ifying the seaice package
135    o introduced an alternative length scale calculation for use in the limiting
136      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
137    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
138    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
139      as well as grad(vort3).  Made it compatible with both approximate form
140      for the cubed sphere and full form of these gradients.  Added flag
141      useFullLeith to select between approximate and full form.  
142    o add "d0" in getcon.F to reduce differences between compilers/platforms
143      update output.txt of exp. fizhi-gridalt-hs
144    o change port_rand funtion to allow to set the seed.
145    o fix obscure MNC bug involving conversion between reals and integers
146      - it caused no problems with certain (eg. gcc, ifc) compilers but the
147        new version is now more standards-compliant
148    o adjoint-related modifications
149      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
150      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
151      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
152    
153    checkpoint57e_post
154    o Adding eddy stress controls a la Ferreira et al.
155    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
156    
157    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
158      update output.txt of exp. fizhi-gridalt-hs
159    o add more "Z" dimensions and associated coordinate vars to MNC
160    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
161    o parameter calendarDumps: when set, approximate months (30-31 days) and years
162      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
163      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
164      months and years.  Requires pkg/cal.
165    o diagnostics: add pickup functionality
166      - off by default for backwards compatibility
167      - current version only uses MDSIO -- MNC will be added
168    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
169    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
170    
171    checkpoint57d_post
172    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
173    o modify verification/ideal_2D_oce so that it tests the creation of mnc
174      output from the diagnostics package
175    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
176    o make genmake2 more portable by using ".$FS" instead of ".f" for more
177      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
178    o add coordinate variables to the MNC output from the diagnostics package
179    o change MNC-flags default value: true when useMNC=TRUE
180    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
181      the ability (off by default) to read the grid information using MNC
182    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
183    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
184    o do snap-shot diagnostics at the middle of the time-interval (instead of
185      at the end).
186    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
187      new test for AIM with thSIce + slab-ocean
188    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
189    o move state variable diagnostics to the beginning of the time step ;
190      (note: still needs some work specially for snap-shot diagnostics)
191      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
192    
193    checkpoint57c_post
194    o Change testing option (-ieee) to get closer agreement between g77 & ifort
195    o generate new output.txt files on faulks with g77 & the new -ieee option
196    checkpoint57c_pre
197    
198    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
199      update output.txt of exp. global_ocean.90x40x15
200    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
201      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
202    o add saltFlux(+File) forcing capability with periodicExternalForcing
203    o allow to use pkg diagnostics for GM-Redi & ThSIce output
204    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
205    o improvements for the MNC output from DIAGNOSTICS:
206      - correct handling of the unlimitied dimension
207      - all dims now have associated coordinate variables
208      - variables located at U, V, and Corner ("Z") points are now written
209        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
210        *all* data points are output
211    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
212    o added pkg/seaice/seaice_monitor.F
213    o mdsio_readfield.F can now read files visible only to master MPI process.
214    o pkg/seaice: some test code for ice-modified ocean stress
215    o exf_getffields interpolation defaults to bilinear for all scalar forcing
216      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
217      spurious negative numbers for precipitation and humidity.  Will cause
218      some small numerical differences for integrations using pkg/exf/exf_interp.F.
219    o pkg/ctrl/
220      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
221        May be enabled via doPackDiag
222      *  introduce z-scaling of
223         + gradient (doZscalePack) and
224         + control (doZscaleUnpack)
225    o pkg/mdsio/
226      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
227      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
228    
229    checkpoint57b_post
230    o simplify options in diagnostics_fill arguments (remove weird combinations)
231    o fix MNC coordinate variables so that they now contain per-face index
232      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
233      general, EXCH2 grids are only aligned to a "local" coordinate system
234    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
235    o Implement instantaneous output within pkg diagnostics:
236      setting a negative frequency in data.diagnostics produces
237     "snap-shot" output (as opposed to time-average if freq > 0)
238    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
239      NOTE: change ptracer diagnostics name: use 2 characters to work with
240            more than 9 tracers. Add also diagnostics of advect & diffus flux.
241    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
242      becomes the coordinate variable for the 'T' dimension
243    o add CF-style coordinate variables to MNC
244      - just a first cut:  numbers are meaningless on the cubesphere and
245        missing along the T axis but otherwise it works!
246    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
247    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
248    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
249      this is based directly on what the model compute, so that the content of
250      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
251    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
252    o clean up build options files for SunOS, in particular
253      - remove -traditional from xmakedepend
254      - change -xarch=v9 to -xarch=native for f77
255      - restore use of make (not gmake)
256      - add CC=gcc if using g77
257    o changes per discussion of AM, JMC, & EH3 today:
258      - move redundant "grid" variables out of "state" -- in preparation of
259        creating proper CF-style coordinate variables and in recognition
260        that any/all grid variables can be easily copied (eg. w/NCO) from
261        the grid files into any of the other NetCDF files
262      - *always* output grid variables with MDSIO (this will eventually be
263        changed)
264      - output MNC grid file if useMNC is true
265    o every instance of _END_MASTER() has been found and replaced with
266      _END_MASTER( myThid ) in order to satisfy certain picky Sun
267      preprocessors
268    o re-arrange diagnostics pkg initialisation:
269     - allow each package to extend the available diagnostics list
270     - add some checking and fix small problems (multi-threaded, ...)
271     - new S/R diagnostics_fill (replace fill_diagnostics):
272       look through the short list of active diag. (instead of the long list)
273       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
274    
275    checkpoint57a_post
276    o this set of changes restores TAMC compatibility
277      tested for global_ocean.90x40x15 adjoint on trough
278      (what a pain)
279    
280    checkpoint57a_pre
281    o some modifs in tools/build_options for sunos
282    o call ctrl_pack for ctrl at end for optimcycle=0
283    
284    checkpoint57
285    o add horizontal bi-harmonic viscosity for vertical velocity
286      - new parameter viscA4W (defaults to viscA4)
287      - affects only non-hydrostatic code
288      - to be done: no-slip lateral boundary conditions
289    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
290    o implement Implicit Vertical advection for pTracers
291    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
292      (implemented also for implicit vertical diffusion & advection)
293    o OBCS: extend application of tracer open boundary conditions
294      to a strip beyond the boundary of width Olx/Oly
295    o add call monitor to TAF set of required calls (flow directives)
296      and include in natl_box_adjoint
297    o untangle a few ifdefs related to cost, ctrl, autodiff
298      untangel a few ALLOW_ECCO_OPTIMIZATION
299    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
300      (theta2, salt2 in ecco_cost_weights)
301    
302    checkpoint56c_post
303    o OBCS as control variables
304      - update ctrl_ad_diff.list, obcs_ad_diff.list
305      - remove balance of obcs controls from default
306      - fix index bug nobcs in ctrl_init
307      - fix dummy fields filen in ctrl_pack
308      - add dummy weights for obcs
309    o lsopt: comment out fort.94 output
310    o optim:
311      - remove unnecessary header files
312      - adjusted namelists
313      - add xerbla.F to Makefile
314    o exf:
315      - multiple modifications of exf_check_range
316      - unit change in exf_init_runoff from [m/year] to [m/s]
317    o mdsio:
318      - i/o-vector change debugLevel from debLevA to debLevB
319    
320    checkpoint56b_post
321    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
322      is called from DO_THE_MODEL_IO
323      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
324      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
325      - clean up PTRACERS_WRITE_TIMEAVE a little
326    o add another verification experiment that tests both the cfc-pkg and
327      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
328      reactive tendencies treated inline with regular timestepping
329    o testreport previously did a lousy job of comparing small numbers, so
330      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
331      implemented in the little c-progam tmp_cmpnum.c which is embedded in
332      testreport.
333    o ptracers_monitor: bug fix for MPI
334    
335    checkpoint56a_post
336    o GCHEM: finish reorganizating the package
337      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
338        (introduces another 3D-array for each passive tracer, but only if
339        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
340        gchemTendency is not needed because the timestep is done separately)
341      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
342      - GCHEM is now---more or less cleanly---separate from PTRACERS
343      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
344        so clear to me how that should be done in a general way.
345    o CFC: improve formatting of output in CFC_ATMOS
346    o PTRACERS:
347      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
348        that ALL experiments with ptracers enable can be checked. This makes
349        GCHEM_MONITOR obsolete.
350      - include a runtime parameter PTRACERS_monitorFreq that defaults to
351        monitorFreq
352      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
353    o add PTRACERS (PTR0[1-5]) to testreport output
354    o exf_check_range:
355      * default changed to .TRUE.
356      * will check values for niter0 if debLevA, every timestep if debLevB
357      * STOP in exf_check_range if 'out of range'
358      * range chosen generous to allow for potential extema
359      TBD: a version with stricter range
360           permitted range would be runtime parameters
361  o GMredi:  o GMredi:
362    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
363    - 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 366  o GCHEM:
366    - 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
367      the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP      the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
368    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
369      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
370        this flag is now only visible within GCHEM-pkg routines.
371      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
372        be replaced by a 3D array that is computed before thermodynamics; for
