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