5      ==============================      ==============================
6    
7    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
8      truncation level) 4/5 MLAdjust test results (11&12 digits match).
9    
10    checkpoint57t_post
11    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
12    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
13      same truncation, independent of the face number: affects affects several
14      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
15    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
16      note that biharmonic viscosity + no-slip was not tested in any experiment.
17    o fix bug in non-linear free-surf side-drag ; generate new output for
18      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
19    o make mnc honor the writeBinaryPrec flag for most kinds of output
20    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
21    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
22      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
23    o add brackets in multi-terms sum to get same truncation, independent of
24      the face number (manage to get exactly same value of gU,gV at the cs-edge)
25      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
26    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
27      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
28      a maximum grid-scale Reynolds number.  Also, changes all length calculations
29      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
30      Suggested values of viscosity parameters found in mom_calc_visc.
31      Many new viscosity diagnostics available.
32    
33    checkpoint57s_post
34    o Add clearing-house for viscosity calculations, mom_calc_visc and
35      correct numerous bugs in LeithD and Smagorinsky discretizations.  
36      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
37      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
38      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
39      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
40      The Strain-Tension form is now called with useStrainTensonVisc=.true.
41      ViscAhStrain and viscAhTension are now retired.
42    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
43    o In response to JMC's bug report, genmake2 now ignores any soft-links
44      that it finds in the *current* directory when searching for files.
45      Soft-links found in any other source directories will still work as
46      they did before.
47    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
48      a C routine to unlimit the stack size
49    o mnc-ify pkg/aim snapshot vars
50    o mnc-ify pkg/land as requested by Daniel
51    o various changes to mnc including:
52      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
53      - output can now be grouped so that all files within a group
54          change the ITER portion of their names in lock-step together
55      - can now read ("global") PER-FACE (in addition to PER-TILE) files
56          and works with both EXCH1 and EXCH2 (but needs more testing)
57      - writing works for all verification test cases w/ g77 on Linux
58    
59    checkpoint57r_post
60    o make MNC variable initialization happen earlier
61    o add diagnostics for (almost) each term of the momentum Eq.
62    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
63    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
64    o remove MINIMAL_TAVE_OUTPUT option ;
65      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
66    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
67      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
68    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
69    o add time-dependent SST, SSS control
70    o cost terms in ecco/ modularized (new cost_generic.F)
71    o cost_averages routines are modularized (new cost_averagesgeneric.F)
72    o new infrastructure for seaice model vs. obs misfits in seaice/
73      * driver from the_main_loop.F is seaice_cost_driver.F
74      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
75      * gradient check in Exp. 6a of natl_box_adjoint/
76    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
77      (see README file)
78    
79    checkpoint57q_post
80    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
81    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
82      - bug was reported by Jean-Michel and Ian Fenty
83    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
84      update exp. cpl_aim+ocn output.
85    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
86      Needed for high-res. runs with large global files
87      to be able to limit tapelev size
88    o Changed some tests for adjoint:
89      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
90      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
91      * global_ocean.90x40x15/ back to default 3-level checkpointing
92    o Modifications to enable scripted COMMON to MODULE conversion
93      * verification/OpenAD/code/ has necessary scripts and description;
94      * converts, compiles and runs successfully;
95    
96    checkpoint57p_post
97    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
98    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
99      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
100    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
101    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
102      (was already the case for dissipation with mom_vecinv,
103       and also the case for grad.PhiHyd when staggered-timeStep)
104      This will allow to put dissipation out-off the AB time-stepping.
105     Unfortunately, affects truncation error. Update output of exp. that "fails"
106      (cg2d matching number) and leave the others for later: front_relax(10),
107      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
108      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
109    
110    checkpoint57o_post
111    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
112      (2) its ready to be documented during the 20050801 DocFest
113    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
114      for ideal_2D_oce and lab_sea on linux_ia32_g77
115    o set to #undef CTRL_SET_OLD_MAXCVARS_30
116      in global1x1_tot/code_seaice_adj to access indices 32, 33
117      (worth another tag)
118    
119    checkpoint57n_post
120    o adding precip control xx_precip 32
121    o adding swflux control xx_swflux 33
122    o Replacing 10 forcing penalty cost routines by 1 generic.
123    o Implementing partitioning in time-mean and variable adjustment
124      for atmos. state.
125    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
126    o in natl_box_adjoint:
127      * updated exp 1 to 10
128        (but does not have time-mean vs. variable split results yet)
129    o updated global1x1/*_seaice_adj/
130      to incorporate latest changes
131    o enable useSingleCpuIO for mdsio vector routines
132      (applies in particular to tapelev I/O)
133    o removed inefficient K-loop in all active_file*control*.F
134    
135    checkpoint57m_post
136    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
137      and advect_cs (use EXCH-2 and standard cs-32 grid files).
138    o pkg/exch2: filling of face-corner halo regions is optional
139      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
140    
141    checkpoint57l_post
142     tag before updating tutorials (pre-release-2)
143    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
144       for output and interpolation of input fields onto model grid)
145    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
146       Affects results of exp. rotating_tank ; update output.txt.
147    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
148          and taking the square quantity and/or using a fraction-weight field.
149    o fix aim_diagnostics_init.F mate numbers.
150    o add mnc output capability to diagnostics/diagstat and update
151      our cvsignore files for the ACSII output generated
152    
153    checkpoint57k_post
154    o lab_sea now uses diagnostics package and provides a suite of
155      new EXF diagnostics output.
156    
157    checkpoint57j_post
158    o exf
159      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
160        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
161        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
162      * extended diagnostics output
163        - now includes all EXF variables
164        - hs, hl moved to common block
165        - separate S/R for diagnostics, called after ctrl vector is added
166        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
167        - EXFqnet contains true Qnet (i.e. includes qsw)
168      * updated verif. lab_sea, global_with_exf
169      * Rearranging hflux (exf_mapfields -> exf_getforcing)
170        to ensure that diagnostics sees a true EXFqnet
171    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
172    o diagnostics pkg: change pointers so that 1 diagnostic can be used
173      several times with different frequencies.
174    o mnc-ify the thsice package as requested by Daniel Enderton
175      - the monitor--MNC output needs work
176      - many attributes need to be added (most are currently blank)
177    o mnc-ify theaim_v23 package as requested by Daniel Enderton
178      - many attributes need to be added (most are currently blank)
179    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
180    o add Sadourny like discretization to the 4th.O vorticity advection scheme
181    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
182      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
183         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
184    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
185     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
186    
187    checkpoint57i_post
188    o Diagnostics package was changed: diagnostic allocation is now deactivated
189      by setting an empty file name in the namelist (used to be by setting 0 frequency)
190    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
191      add 1rst Order upwind vertical Shear.
192    o add a quick fix for A/B checkpointing in OFFLINE mode
193    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
194      end-run around the C/Fortran linking horror in eesup/src/timers.F
195    o added pkg/runclock: allows user to terminate run based on wall clock
196    o added non-hydrostatic scaling parameter: nh_am2
197    o pkg/my82: futile attempt to make results compiler-independent by adding
198      some "_d 0", etc. no effect.
199    o for mnc output, fill the 'T' coordinate var with myTime and create a
200      separate 'iter' variable for iteration count
201    o pkg/diagnostics:
202      add new capability: output of Global/Regional & per-level statistics ;
203      tested against monitor output (including land & thSIce) on various exp.
204    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
205    
206    checkpoint57h_done
207      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
208      data.diagnostics, data.gchem, data.ptracers) is done.
209    
210    o pkg/diagnostics: prepare for Global/Regional statistics.
211      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
212    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
213      and rename it: DIFFERENT_MULTIPLE
214    
215    checkpoint57h_post
216    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
217    o pkg/diagnostics: change output frequency, now in seconds (instead
218      of Nb of iterations). This requires to change data.diagnostics.
219    checkpoint57h_pre
220    
221    o in mnc, let the user create the output dir if both mnc_outdir_date
222      and mnc_outdir_num are false
223    o add fflags() to pkg/diagnostics which allows one to specify, on a
224      per-file basis, the file precision [default behavior is unchanged]
225    o added diagnostics to pkg/kpp, including computation of mixed layer
226      depth based on a temperature/density criterion
227    o updated verification/natl_box to test the new pkg/kpp diagnostics
228    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
229    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
230    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
231      not mnc -- this mistake was found by JMC and is now corrected
232    
233    checkpoint57g_post
234    o add Adams-Bashforth 3rd Order time stepping:
235      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
236      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
237    checkpoint57g_pre
238    
239    o make lambda[Theta,Salt]ClimRelax spatially varying
240      (default remains spatially uniform constant based on tau)
241    o added new control variables
242      * init. uVel, vVel, etanN
243      * lambda[Theta,Salt]ClimRelax
244    o separate masks used for ctrl_pack/unpack 'from write_grid' output
245      (suggested by G. Forget)
246    
247    checkpoint57f_post
248    o add parameter "baseTime" = model base time = time at iteration zero
249      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
250      account for baseTime shift
251    o move Coriolis arrays from PARAMS.h to GRID.h
252    checkpoint57f_pre
253    
254    o mnc-ifying the seaice package
255    o introduced an alternative length scale calculation for use in the limiting
256      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
257    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
258    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
259      as well as grad(vort3).  Made it compatible with both approximate form
260      for the cubed sphere and full form of these gradients.  Added flag
261      useFullLeith to select between approximate and full form.  
262    o add "d0" in getcon.F to reduce differences between compilers/platforms
263      update output.txt of exp. fizhi-gridalt-hs
264    o change port_rand funtion to allow to set the seed.
265    o fix obscure MNC bug involving conversion between reals and integers
266      - it caused no problems with certain (eg. gcc, ifc) compilers but the
267        new version is now more standards-compliant
268    o adjoint-related modifications
269      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
270      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
271      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
272    
273    checkpoint57e_post
274    o Adding eddy stress controls a la Ferreira et al.
275    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
276    
277    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
278      update output.txt of exp. fizhi-gridalt-hs
279    o add more "Z" dimensions and associated coordinate vars to MNC
280    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
281    o parameter calendarDumps: when set, approximate months (30-31 days) and years
282      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
283      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
284      months and years.  Requires pkg/cal.
285    o diagnostics: add pickup functionality
286      - off by default for backwards compatibility
287      - current version only uses MDSIO -- MNC will be added
288    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
289    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
290    
291    checkpoint57d_post
292    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
293    o modify verification/ideal_2D_oce so that it tests the creation of mnc
294      output from the diagnostics package
295    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
296    o make genmake2 more portable by using ".$FS" instead of ".f" for more
297      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
298    o add coordinate variables to the MNC output from the diagnostics package
299    o change MNC-flags default value: true when useMNC=TRUE
300    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
301      the ability (off by default) to read the grid information using MNC
302    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
303    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
304    o do snap-shot diagnostics at the middle of the time-interval (instead of
305      at the end).
306    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
307      new test for AIM with thSIce + slab-ocean
308    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
309    o move state variable diagnostics to the beginning of the time step ;
310      (note: still needs some work specially for snap-shot diagnostics)
311      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
312    
313    checkpoint57c_post
314    o Change testing option (-ieee) to get closer agreement between g77 & ifort
315    o generate new output.txt files on faulks with g77 & the new -ieee option
316    checkpoint57c_pre
317    
318    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
319      update output.txt of exp. global_ocean.90x40x15
320    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
321      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
322    o add saltFlux(+File) forcing capability with periodicExternalForcing
323    o allow to use pkg diagnostics for GM-Redi & ThSIce output
324    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
325    o improvements for the MNC output from DIAGNOSTICS:
326      - correct handling of the unlimitied dimension
327      - all dims now have associated coordinate variables
328      - variables located at U, V, and Corner ("Z") points are now written
329        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
330        *all* data points are output
331    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
332    o added pkg/seaice/seaice_monitor.F
333    o mdsio_readfield.F can now read files visible only to master MPI process.
334    o pkg/seaice: some test code for ice-modified ocean stress
335    o exf_getffields interpolation defaults to bilinear for all scalar forcing
336      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
337      spurious negative numbers for precipitation and humidity.  Will cause
338      some small numerical differences for integrations using pkg/exf/exf_interp.F.
339    o pkg/ctrl/
340      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
341        May be enabled via doPackDiag
342      *  introduce z-scaling of
343         + gradient (doZscalePack) and
344         + control (doZscaleUnpack)
345    o pkg/mdsio/
346      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
347      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
348    
349    checkpoint57b_post
350    o simplify options in diagnostics_fill arguments (remove weird combinations)
351    o fix MNC coordinate variables so that they now contain per-face index
352      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
353      general, EXCH2 grids are only aligned to a "local" coordinate system
354    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
355    o Implement instantaneous output within pkg diagnostics:
356      setting a negative frequency in data.diagnostics produces
357     "snap-shot" output (as opposed to time-average if freq > 0)
358    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
359      NOTE: change ptracer diagnostics name: use 2 characters to work with
360            more than 9 tracers. Add also diagnostics of advect & diffus flux.
361    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
362      becomes the coordinate variable for the 'T' dimension
363    o add CF-style coordinate variables to MNC
364      - just a first cut:  numbers are meaningless on the cubesphere and
365        missing along the T axis but otherwise it works!
366    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
367    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
368    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
369      this is based directly on what the model compute, so that the content of
370      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
371    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
372    o clean up build options files for SunOS, in particular
373      - remove -traditional from xmakedepend
374      - change -xarch=v9 to -xarch=native for f77
375      - restore use of make (not gmake)
376      - add CC=gcc if using g77
377    o changes per discussion of AM, JMC, & EH3 today:
378      - move redundant "grid" variables out of "state" -- in preparation of
379        creating proper CF-style coordinate variables and in recognition
380        that any/all grid variables can be easily copied (eg. w/NCO) from
381        the grid files into any of the other NetCDF files
382      - *always* output grid variables with MDSIO (this will eventually be
383        changed)
384      - output MNC grid file if useMNC is true
385    o every instance of _END_MASTER() has been found and replaced with
386      _END_MASTER( myThid ) in order to satisfy certain picky Sun
387      preprocessors
388    o re-arrange diagnostics pkg initialisation:
389     - allow each package to extend the available diagnostics list
390     - add some checking and fix small problems (multi-threaded, ...)
391     - new S/R diagnostics_fill (replace fill_diagnostics):
392       look through the short list of active diag. (instead of the long list)
393       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
394    
395    checkpoint57a_post
396    o this set of changes restores TAMC compatibility
397      tested for global_ocean.90x40x15 adjoint on trough
398      (what a pain)
399    
400    checkpoint57a_pre
401    o some modifs in tools/build_options for sunos
402    o call ctrl_pack for ctrl at end for optimcycle=0
403    
404    checkpoint57
405    o add horizontal bi-harmonic viscosity for vertical velocity
406      - new parameter viscA4W (defaults to viscA4)
407      - affects only non-hydrostatic code
408      - to be done: no-slip lateral boundary conditions
409    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
410    o implement Implicit Vertical advection for pTracers
411    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
412      (implemented also for implicit vertical diffusion & advection)
413    o OBCS: extend application of tracer open boundary conditions
414      to a strip beyond the boundary of width Olx/Oly
415    o add call monitor to TAF set of required calls (flow directives)
416      and include in natl_box_adjoint
417    o untangle a few ifdefs related to cost, ctrl, autodiff
418      untangel a few ALLOW_ECCO_OPTIMIZATION
419    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
420      (theta2, salt2 in ecco_cost_weights)
421    
422    checkpoint56c_post
423    o OBCS as control variables
424      - update ctrl_ad_diff.list, obcs_ad_diff.list
425      - remove balance of obcs controls from default
426      - fix index bug nobcs in ctrl_init
427      - fix dummy fields filen in ctrl_pack
428      - add dummy weights for obcs
429    o lsopt: comment out fort.94 output
430    o optim:
431      - remove unnecessary header files
432      - adjusted namelists
433      - add xerbla.F to Makefile
434    o exf:
435      - multiple modifications of exf_check_range
436      - unit change in exf_init_runoff from [m/year] to [m/s]
437    o mdsio:
438      - i/o-vector change debugLevel from debLevA to debLevB
439    
440    checkpoint56b_post
441    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
442      is called from DO_THE_MODEL_IO
443      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
444      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
445      - clean up PTRACERS_WRITE_TIMEAVE a little
446    o add another verification experiment that tests both the cfc-pkg and
447      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
448      reactive tendencies treated inline with regular timestepping
449    o testreport previously did a lousy job of comparing small numbers, so
450      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
451      implemented in the little c-progam tmp_cmpnum.c which is embedded in
452      testreport.
453    o ptracers_monitor: bug fix for MPI
454    
455    checkpoint56a_post
456    o GCHEM: finish reorganizating the package
457      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
458        (introduces another 3D-array for each passive tracer, but only if
459        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
460        gchemTendency is not needed because the timestep is done separately)
461      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
462      - GCHEM is now---more or less cleanly---separate from PTRACERS
463      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
464        so clear to me how that should be done in a general way.
465    o CFC: improve formatting of output in CFC_ATMOS
466    o PTRACERS:
467      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
468        that ALL experiments with ptracers enable can be checked. This makes
469        GCHEM_MONITOR obsolete.
470      - include a runtime parameter PTRACERS_monitorFreq that defaults to
471        monitorFreq
472      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
473    o add PTRACERS (PTR0[1-5]) to testreport output
474    o exf_check_range:
475      * default changed to .TRUE.
476      * will check values for niter0 if debLevA, every timestep if debLevB
477      * STOP in exf_check_range if 'out of range'
478      * range chosen generous to allow for potential extema
479      TBD: a version with stricter range
480           permitted range would be runtime parameters
481    o GMredi:
482      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
483      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
484      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
485    o GCHEM:
486      - move call to GCHEM_FORCING_SEP, so that it is now called before
487        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
488      - introduced a useGCHEM runtime flag and applied it everywhere.
489      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
490        this flag is now only visible within GCHEM-pkg routines.
491      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
492        be replaced by a 3D array that is computed before thermodynamics; for
493        this, the tracer ID iTracer had to be included into the parameter list
494        of ptracers_forcing
495      - set up forward_step to call gchem_forcing, that will replace
496        gchem_forcing_int in ptracers_forcing
497      - cleaning up
498    o small cleaning of exch2: remove files that are also in eesupp/src
499    
500    checkpoint56
501    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
502    o mnc: cleanup "full" files--fixes out-of-memory problem
503    o ECCO-GODAE
504      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
505      * fully merged and updated from SIO code
506        windstress sign change affects
507        - exf_inscal_[u/v]stress
508        - sign of xx_tau[u/v] adjustments
509        - signs in cost_scat
510      * ctrl_get_gen: avoid update of tau[u/v] for first few days
511      * natl_box_adjoint updated and compressed
512      * 2-level checkpoint switch added
513        (tested in EXP. 1 of natl_box_adjoint)
514      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
515    o SVD
516      * first complete, non-hacked version for SVD calculations
517      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
518        performed via direct access files admtlm_vector.it????
519        (via ctrl_[un]pack)
520      * optimcycle is used for ARPACK iteration counter
521        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
522      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
523        and add linear transforms where necessary
524      * controls are initial/final SST, SSS (can be extended; need to check
525        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
526    o mdsio: filename info to both stderr, stdout
527    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
528      from sign change
529    
530    checkpoint55j_post
531    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
532      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
533    o add consistent build directories and .cvsignore files to verification
534    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
535    o make all subroutines 30 or less characters in length for certain older
536      compilers to work (a thorough search only turns up two routines in
537      pkg/ptracers)
538    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
539      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
540    
541    checkpoint55i_post
542    o change arrays for total vertical diffusivity (2.D if explicit,
543      3.D if implicit) ; each ptracer uses its own background value.
544    o added mnc/NetCDF output capability to ocn_compon_interf
545      - added bits to verification/cpl_aim+ocn so that it can run on
546        ITRDA and other clusters without the mpirun "-wd" option
547    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
548      configuration
549    o give MNC the ability to create additional files rather than
550      exceeding a specified file size limit "MNC_MAX_FILESIZE"
551      - the default is just less than 2GB which is a practical limit
552        on many systems
553    o Compute the non-local term using either KPP vertical diffusivity (=default)
554       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
555    
556    checkpoint55h_post
557    o add verification test "vermix"
558    o remove all the *_ioinc flags and replace with the single global
559      outputTypesInclusive flag
560    o allow to set a vertical profile of vertical diffusivity for T & S
561    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
562    o useMNC moved from data.mnc to data.pkg
563    
564    checkpoint55g_post
565    o Renaming carbon AD experiments to comply with testreport conventions
566    o Updating adjoint of Held-Suarez hs94.1x64x5
567    o Fixing directives for non-ECCO forward_step, after ECCO directives
568      have been fixed to avoid recomp. of do_oceanic_phys
569      Works well for global_ocean.90x40x15,
570      but recomp. issue remains for carbon
571    o Updating adjoint output for natl_box_adjoint after
572      pkg/ecco has been modified (see taga c55d_post)
573    
574    checkpoint55f_post
575    o rename to timeave_init_fixed
576    
577    checkpoint55e_post
578    o some delicate re-shuffle of store directives to avoid one
579      extra call of do_oceanic_physics
580      affects ecco_the_main_loop.F, do_oceanic_physics.F
581      checkpoint_lev1_directives.h
582    o NB: this may break global_ocean adjoint temporarily,
583      but it is clear how to fix it. Will do later, need this now.
584    
585    checkpoint55d_post
586    o ECCO specific cost function terms (up-to-date with 1x1 runs)
587    o ecco_cost_weights is modified to 1x1 runs
588    o modifs to allow observations to be read in as
589      single file or yearly files
590    o enable to read exf forcing fields as either
591      single file or yearly files (flag useExfYearlyFields)
592    checkpoint55d_pre
593    
594    o switch between 2-level and 3-level checkpointing
595    o add ability of MNC to write local and "partial" (eg. 2D slices where
596      the full 3D field is never actually stored) arrays to NetCDF files
597      with the correct (that is, the complete multi-dimensional) set of
598      array indicies
599      - used in mom_vecinv() to write the diagFreq output
600      - tested (demonstrated) in verification/aim.5l_cs
601    o further mnc-ification
602      - add verification/lab_sea to the list with mnc setups
603      - fix undefined mnc v-names in cd_code
604      - add kpp to mnc output (both snapshot and timeave)
605    o non-hydrostatic code
606      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
607        in calc_gw.F
608      - defaults to viscAh
609      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
610        friction or Leith) in non-hydrostatic mode, as long as there is
611        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
612    o pkg/cost
613      extend simple cost functions to treat time mean quantities
614      (T,U,V) via cost_accumulate_state from cost_tile
615    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
616        be 2 times larger than the minimum size the advection scheme requires.
617        now get a perfect conservation of salt in advect_cs test-exp (updated)
618    o GGL90 (Gaspar's TKE mixed layer)
619      - add horizontal diffusion of TKE, requires exchanges in
620        do_fields_blocking_exchanges, horizontal diffusivity is zero by
621        default. In OPA there is no horizontal diffusion of TKE but the
622        mixing coefficients are computed from a horizontal average of TKE of
623        6 points or so. I think that diffusion has a little more physical
624        justification.
625      - clean up ggl90_calc in the hope of reducing memory usage (this hope
626        was in vain)
627      - mask tke-variable in ggl90_init
628    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
629    o fix biharmonic diffusion on CS-grid.
630    o more obcs stuff
631      - added obcs_external_fields_load as an alternative to the EXF-pkg option
632        for reading boundary values. This routine is called from
633        obcs_prescribe_read
634      - updated obcs_check
635      - changed sponge layer relaxation parameter units for days to seconds
636      - turned off sponge layer by default
637      - changed argument list of OBCS_CALC to myTime+deltaTclock
638      - fixed about 35 bugs in obcs_external_fields_load
639    
640    checkpoint55c_post
641    o obcs stuff
642      - new runtime flags useOBCSprescribe, useOBCSbalance
643      - re-arranged obcs_calc
644      - moved exf_getobcs to obcs_prescibe_read
645        obcs_prescibe_read is called after ORLANSKI stuff
646        and independent of it (executable can contain all).
647      - updated obcs_check
648      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
649        These may be necessary only if tangential velocities are
650        prescribed at OB, not sure, needs testing.
651    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
652      which simplifies the calls and passes the ifc check-bounds test
653    
654    checkpoint55b_post
655    o add a 2D scalar, Z location, exchange_2 routine.
656    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
657      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
658      affects advect_cs results (for the wrong reason): update output.txt
659    o use a more standard discretization for biharmonic viscosity ;
660     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
661      affects results of dome set-up: update output.txt
662    o fix gad_advection.F (CubedSphere part), back to version 1.23
663    o fix bug in mom_vi_del2uv.F (CubedSphere part).
664    
665    checkpoint55a_post
666    o merged code to
667      * prescribe/read time-dependent open boundaries
668        (works in conjunction with exf, cal)
669      * sponge layer code for open boundaries
670      * each boundary N/S/E/W now has its own CPP option
671        (healthy for the adjoint)
672    
673    checkpoint55
674    o up-to-date adjoint of previous breaks
675      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
676      - global_ocean_ebm: adjoint still needs fix (TLM ok)
677      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
678      - carbon: * remove tr1-related adjoint verification
679                * add ptracer as control variable
680    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
681      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
682    
683    checkpoint54f_post
684    o in verification/carbin/ remove experiment related to
685      ALLOW_PASSIVE_TRACER (array tr1 etc)
686      code_ad/ input_ad/ results_ad
687    
688    o add two new packages
689      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
690        + subject to optimization (memory)
691      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
692        + subject to reordering (many GOTOs in the original code)
693        + so far opps is called for every (i,j) point, and then operates in
694          the vertical; one may want to reorder the scheme in order operate in
695          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
696          fields)
697    o overhaul of IO so that we now have flags for MDSIO and/or MNC
698      - all verification tests compile and run with linux_ia32_g77
699      - defaults are compatible with current input files--nothing
700        should change if you were not previously using MNC
701      - MNC output has been added in numerous places (eg. timeave)
702        but there are still a few writes not yet do-able with MNC
703        (this is in progress)
704      - flags now allow for either/or/both use of MDSIO and MNC and
705        documentation will soon follow
706      - numerous small formatting cleanups for ProTeX
707    o add version info (via BUILD_INFO.h) to MNC and stdout
708    
709    checkpoint54e_post
710    o add two new packages
711      - pp81 (Packanowski and Philander, 1981), Richardson number and
712        stratification dependent mixing
713      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
714      - these scheme operate in a similar manner as KPP (without ghat, of
715        course), however there is only one diffusivity that is used for both
716        temperature and salinity (and passive tracers)ç
717    o add offline package
718    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
719      provided by Stephanie Dutkiewicz
720    o genmake2: add ability to search for C compilers and cleanup test output
721      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
722    
723    checkpoint54d_post
724    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
725    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
726      leading to additional shift by 5 days each year of integration
727       (i.e. leading to considerable offset over the years)
728    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
729    o start with no AB and no initial filtering (staggerTimeStep):
730      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
731    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
732      (external loading & cpl import/export stay in forward_step.F)
733    o update coupling interface to work with new staggerTimeStep
734    o change MDSIO ptracers_pickup.
735    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
736    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
737    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
738    
739    checkpoint54c_post
740    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
741      this affects (truncation error) output.txt of test-exp:
742       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
743    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
744    o change Qnet to always be the net heat flux, (+upward).
745      affects (truncation error) output of natl_box exp.: updated
746    o define the max number of passive tracers in PTRACERS_SIZE.h
747    o start to test mnc routinely in exp0
748    o add sea-ice loading (sIceLoad) as a new forcing field.
749    
750    checkpoint54b_post
751    o add testreport "-j JOBS" option for parallel builds (tested and pretty
752       impressive on Altix and Opteron systems)
753    o diagnostics can now write NetCDF files through the mnc package
754    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
755    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
756    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
757      affects (truncation error) output of lab_sea & natl_box exp.: updated
758    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
759    
760    checkpoint54a_post
761    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
762    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
763    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
764    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
765      + internal_wave (shift in writing cg2d_ini_res)
766    checkpoint54a_pre
767    
768    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
769      - modified verification/lab_sea and natl_box_adjoint accordingly
770    
771    checkpoint54
772    checkpoint53g_post
773    o prepare splitting of thermodynamics: store convect.counter in common block
774    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
775      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
776    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
777    o new parameter "nShapS": allow to treat differently S from T (nShapT)
778    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
779    o restore adjointability
780    
781    checkpoint53f_post
782    o modifications that affect AIM experiment results (update output.txt):
783      - no advection of S at top interface Nr (pkg/generic_advdiff)
784      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
785    o AIM pkg:
786      - include stability function into surf.Flux derivative relative to Tsurf
787      - calculate clear-sky radiation & surface temp. change (for diagnostics)
788    
789    checkpoint53e_post
790    o merged cylindrical coord configuration
791    o added rotating_tank experiment
792    checkpoint53e_pre
793    
794    checkpoint53d_post
795    o faulks upgraded: re-generate output.txt that have changed:
796       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
797    o Added Bryan and Lewis, 1979, vertical diffusivity profile
798    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
799    o added Sadourny discretization of Coriolis
800      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
801      - re-enabled use of omega3 (useAbsVorticity)
802    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
803      vector-invariant equations
804      - note: does *NOT* yet use same variable visc. for no-slip BC's.
805    o recoded the lateral boundary conditions for non-hydrostatic w, this time
806      hopefully without new bugs
807      - still to do: biharmonic friction for non-hydrostatic w
808    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
809    o regenerated output for global_ocean_ebm (using -ieee)
810    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
811      of mom_common/
812      - simple re-arrangement of instructions within computing loop
813    checkpoint53d_pre
814    
815    checkpoint53c_post
816    o new version of coupler for AIM+thSIce and Ocean models
817     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
818     - land: change Evaporation of snow
819     - aim with thSIce: fix bug in snow-precip.
820    o changes to calc_gw.F
821     - bug fix for w^2 term near the bottom boundary
822     - (hopefully) improve the lateral slip boundary condtions for use with
823        partial/looped cells
824      - because the bug fix changes two verification experiments anyway (exp5
825        and plume on slope), change the lateral boundary condition from half slip
826        to the value of no_slip_sides
827    o ebm package wasnt quite up to the parallel task. Fixed that.
828    o Adjoint of EBM package + verification
829      * TLM OK
830      * ADM not sufficient accuracy yet (needs further testing)
831    
832    checkpoint53b_post
833    o Commiting new energy balance model to repository
834      * package is pkg/ebm
835      * verif. is verification/global_ocean_ebm
836      * references are in ebm_driver.F
837    C      * X. Wang, P. Stone and J. Marotzke, 1999:
838    C        Global thermohaline circulation. Part I:
839    C        Sensitivity to atmospheric moisture transport.

841    C      * X. Wang, P. Stone and J. Marotzke, 1999:
842    C        Global thermohaline circulation. Part II:
843    C        Sensitivity with interactive transport.

845    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
846    C        Destabilization of the thermohaline circulation
847    C        by atmospheric eddy transports.
848    C        J. Climate 7(12), 1870-1882
849    o Will need long integration testing.
850    checkpoint53b_pre
851    
852    o created pkg/mom_common in preparation for variable viscosity code
853    o renamed and split ini_mnc_io
854    o pkg/land: only liquid water can diffuse or run-off
855    o AIM using land: soil wetness availability account for snow
856    o added printMapIncludesZeros to EEPARMS namelist
857    
858    checkpoint53a_post
859    o restore TAMC compatiility for exf_constants.h
860      (no usage of _d in .h)
861    o Additional storing in KPP in an attempt to fix
862      TAMC problem with adjoint of KPP code.
863      (no success...)
864      Identical code works fine with TAF.
865    o Fixed verification/natl_box_adjoint experiments.
866      Initial conditions for Experiments 4 and 5 are now
867      set to "SEAICE_initialHEFF=0", which is more reasonable,
868      and hence gives results closer to that of Experiment 2.
869      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
870    
871    checkpoint53
872    o stable checkpoint with up to date adjoint
873      TLM tests only run for 1st grdchk at the moment. Its unclear if
874      this is a code problem or a problem with resetting code for g_
875      variables that is being autogenerated wrong.
876      Otherwise:
877       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
878       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
879         are both still in chaos following their security messes.
880    
881    checkpoint52n_post
882    o various build (mostly genmake2) changes including:
883      - ability to build/run more easily within Cygwin and MacOS X
884      - more complicated Makefiles with a stronger dependence on Gnu Make
885    o pkg/seaice modifications
886      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
887        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
888        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
889      - changed proxy for geostrophic velocity and updated
890        verification/lab_sea/results/* accordingly
891      - removed ADI dynamic solver from pkg/seaice
892      - replaced all occurrences of 1/CSTICE or 1/CSUICE
893        they caused a segmentation fault under certain circumstances
894      - removed unused field WATR
895    o bug fix in exf-package:
896      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
897         now reflect that.
898    o small fixes in the cal-package:
899      - set reference date to first of January for the 'model'-calendar
900      - failing of cal_CheckDate in cal_FullDate now actually results in a
901        warning
902    o small modifications in exf-package to increase flexibility:
903      - change climtempfreeze from a constant to a runtime parameter that
904        is specified in data.exf_clim (default = -1.9)
905      - introduce runtime parameter windstressmax (default = 2.0) that is
906        specified in data.exf
907    o fix in pkg/thsice:
908      - update Evap (Tsf changes) to be consistent with Latent heat flux
909      - maintain snow precipitation unchanged (even if Tsf >=0).
910     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
911    
912    checkpoint52m_post
913    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
914      this does not change any of the results, because myIter=0 in swfrac always
915      lead to jwtype=2 (the default anyway), but the call makes little sense
916      as a default
917    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
918    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
919      atmospheric model (AIM) to use it ; add a "slab ocean" component.
920    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
921    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
922    o extending useSingleCpuIO option to work with new exch2 I/O format
923      - old-style, missing-tile I/O is still accessible by defining CPP
924        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
925    o monitor package can write to NetCDF files and/or STDOUT
926    o fix re-definition bug in MNC_GRID_INIT_ALL()
927    o doc/api_reference added
928      - a framework for building an API Reference Manual using all
929        the "protex" comments embedded in the code
930      - see pkg/generic_advdiff, pkg/mnc for examples
931    o MNC:
932      - make myThid the last argument for all subroutines
933      - new default for the grid files: NO halos
934      - add useMNC and other run-time flags
935      - separate per-file-group handling of the unlimited dimension
936      - early initialization of MNC w/ flags read at the eeboot stage
937        and lookup tables set in initialize_fixed
938      - write all MNC output to a freshly-created directory
939    o thermodynamics sea-ice (thsice) is now tested with testreport.
940    o test exp. advect_cs: use the standard cs32 grid ; update output.
941    o Added functionality to grdchk:
942      pick global i,j,k position (or nearest wet) where to perform check.
943    
944    checkpoint52l_post
945    o new land formulation:
946      a) use ground enthalpy as prognostic variable to ensure exact
947         energy conservation.
948      b) account for water temperature and for latent heat of freezing
949         in all processes (rain, run-off, ground storage)
950      c) compute surface and ground temperature implicitly.
951    o aim_v23 modification for new land model:
952      a) Treat separately land / ocean / sea-ice surface fluxes
953         to allow implicit computation of land & sea-ice surface temp.
954      b) add snow precipitation.
955    checkpoint52l_pre
956    
957    o fix problem (when 1 tile is empty) in min/max monitor.
958    o fix bug in timeAve (u,vZetatave in common block)
959    o no restoring terms under ice for pkg/seaice
960    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
961    o bug fix for pkg/seaice pickups
962    o change MNC call locations and add coordinate attributes
963    o mask vorticity at the corner ; affects global_ocean.cs output
964    o fix ini_curvilinear_grid ; test CS experiments with mpi
965    o aim.5l_cs: modify sea-ice fraction input file ; update output
966    o exf: Adding simple range check routine for exf fields after read
967    
968    checkpoint52k_post
969    o removed top-level directory "diags"
970      - we migrated these functions to pkg/timeave a long time ago
971    o fixed bug introduced in pkg/monitor
972    o accuracy ctrlprec = 32 insuffient for gradient checks using
973      averaged fields (I/O via cost_averages)
974      -> use ctrl.h in active_file*.F to control I/O precision.
975    o paramter list of CALL ADTHE_MAIN_LOOP
976    o added initial do_the_model_io to ecco
977    o set all ...Freq to zero after cost_final
978      taveFreq, dumpFreq, pChkptFreq
979    o MAIN and ECCO differentiability restored
980    
981    checkpoint52j_post
982    o fix nchklev in tamc.h for global_ocean...
983    o Bringing flow and store directives up-to-date
984    o Really weird thing!
985      call do_the_model_io from the_main_loop with parameters
986      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
987      TAF places a faulty re-call of initialise_varia
988      after cost_final call which should not be there!
989    checkpoint52j_pre
990    
991    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
992      error messages
993    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
994    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
995      debug output
996    o modfied mdsio_writefield.F to handle non-global files under exch2
997    o update AIM Cubed-Sphere exp (aim.5l_cs):
998      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
999    o update AIM Equatorial Channel exp:
1000      use standard aim_v23 pkg and change the SST fields to be more realistic.
1001    o globalFile now works with exch2
1002    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1003      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1004    o limit timeave output for hi-res integrations
1005    
1006    checkpoint52i_post
1007    o removed CPP_EEOPTIONS.h from verification/*/code
1008    o updated the tiling for global_ocean_pressure
1009    checkpoint52i_pre
1010    
1011    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1012      the old pkg/aim).
1013    
1014    checkpoint52h_pre
1015    o shortened offending lines in exch2_send_rx?.template
1016    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1017    o genmake2: add build & execute test for NetCDF code
1018    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1019      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1020    o added useSingleCPUIO flag to monitor.F and mon_out.F
1021    o added temporary hack for sea-ice dynamics on the cube:
1022      metric terms are ignored and it is assumed that
1023      there is no sea-ice on cube faces 1, 2, 4, and 5.
1024    
1025    checkpoint52f_post
1026    o added exch2 cube routines to pkg/exch2
1027    o modified hs94.cs-32x32x5 to use it
1028    o added new grid files to hs94.cs-32x32x5
1029    checkpoint52f_pre
1030    
1031    checkpoint52e_post
1032    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1033      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1034    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1035      to work with implicit vertical advection and AB ;
1036    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1037    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1038     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1039    checkpoint52e_pre
1040    
1041    o fix bug in impldiff when Nr=1 or Nr=2.
1042    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1043    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1044    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1045      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1046    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1047    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1048    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1049    
1050    checkpoint52d_post
1051    o re-tiled many expts to allow comparison in multi-processor mode
1052      - updated output accordingly
1053      - changed hs94.128x64x5 to use intial T from file rather than use the
1054        random number generator
1055    o add infrastructure in model routines for fizhi and gridalt packages
1056    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1057    o changes to permit hi-res, cubed-sphere, configuration
1058      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1059      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1060      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1061        of surface winds for the cube
1062      (A verification experiment, based on global_ocean.cs32x15, but with
1063       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1064       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1065       complete with example surface forcing files and matlab scripts to look
1066       at the output and compare it with that of global_ocean.cs32x15.)
1067    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1068       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1069       to conform to the common rule.
1070    o check-in the first version of the coupler + interfaces for multi-components
1071       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1072       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1073       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1074       - ocean and atmos. share the same horizontal grid (no interpolation).
1075       - exchanges between component and coupler is done in forward_step
1076    o new verification experiment, cpl_aim+ocn:
1077       coupled ocean - AIM atmosphere on cs32 grid.
1078    
1079    checkpoint52d_pre
1080    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1081    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1082    
1083    checkpoint52c_post
1084    o Fixing OPTIONS files for use of exf:
1085      - ALLOW_ECCO not needed
1086      - ECCO_CPPOPTIONS.h should not be included from
1087        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1088        as has been the case in the past
1089      - All cal/exf related options are currently set in
1090        single header file. Should remain so until we
1091        agree on a consistent new policy.
1092    o Removed all CPP options for cal package.
1093      cal has no more CPP options.
1094    o modified STOREs in GAD_ADVECTION
1095    o corrected key comp. for passkey
1096    
1097    checkpoint52b_post
1098    o new version: "thsice" of thermodynamic sea-ice pkg:
1099     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1100     - modify fluxes but do not change theta directly;
1101     - light cleaning of bulk_force pkg (still needed with thsice).
1102     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1103       + output_thsice.txt to test thsice & bulk_force pkgs.
1104    o put back grid & coriolis monitor output.
1105    checkpoint52b_pre
1106    
1107    o call "do_the_model_io" at the beginning (=> dump initial state)
1108    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1109    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1110      (need info on NUMBER_OF_PTRACERS)
1111    o missing PTRACERS headers in some routines
1112    o default tamc.h in pkg/autodiff supposed to crash
1113      to ensure proper customization
1114    
1115    checkpoint52a_post
1116    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1117      - moved surfaceTendencyTice from pkg/seaice to main code
1118      - subroutine FREEZE_SURFACE now limits only surface temperature
1119        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1120        => new output.txt for global_ocean.cs32x15 & global_with_exf
1121      - keep the old version of FREEZE for backward compatibility;
1122        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

1137    o this is the post-merge tag of the ecco-branch
1138      (needs another clean checkout and re-testing)
1139    o various natl_box_adjoint configs and results
1140      but no input fields

1149    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1150    
1151    checkpoint51t_post
1152    o this is the pre-merge tag of the ecco-branch
1153    
1154    checkpoint51s_post
1155    o cleanup: removed various obsolete #define-s
1156    o pkg/grdchk
1157      - renamed 'ph-grd 3' to 'grad-res'
1158      - merged from ecco-branch
1159        (remaining bug fixes for obcs gradient checks)
1160      - additional high-precision output for testreport

1182    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1183    
1184    checkpoint51p_post
1185    o create initial cd_code package
1186      - WARNING: the initialization of fields within packages
1187        is broken because INI_FIELDS (where READ_CHECKPOINT is
1188        called) is called *before* PACKAGES_INIT_VARIABLES.
1189        This seems to be backwards since
1190        1) its important to initially zero the entire field including
1191           the "halo" region
1192        2) zeroing needs to be done *before* reading pickup info
1193           and the pickup call might or might not happen in any
1194           particular run
1195      - this needs an overhaul for R2
1196    o cleanup verification/*/code/GMREDI_OPTIONS.h

1231      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1232      - subroutine FREEZE now limits only surface temperature
1233        (this means new output.txt for global_ocean.90x40x15,
1234         global_ocean.cs32x15, and global_with_exf)
1235    o added surface flux output variables to TIMEAVE_STATVARS

1324    o Added on-the-fly spatial interpolation capability
1325        "USE_EXF_INTERPOLATION" to pkg/exf.
1326      - This is a temporary Cartesian-grid hack until
1327        the super-duper ESMF coupler becomes available.
1328      - See verification/global_with_exf/README for usage example.
1329      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
1330        flags and modified pkg/seaice accordingly.
1331    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
1332        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
1333        non-local transport term.
1334    
1335    checkpoint51e_post
1336    o pkg/mom_vecinv:
1337      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)

1362      - debLevB: equivalent to current debugMode=.TRUE.
1363    o introducing pathname variable mdsioLocalDir for mdsio
1364      that can be specified at runtime
1365      (relevant for cluster I/O to local disk)
1366    `
1367    >>>checkpoint51b_post
1368    adjoint of ptracers
1369    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1370    o extended state in checkpoint_lev?, etc.
1371    o alternative ctrl/cost with tr1 or ptracer
1372    o new comlev1_bibj_ptracers
1373    o new ptracers.flow
1374    o made ptracers_forcing same as external_forcing_s
1375    o added verification for adjoint with ptracers
1376      - adm. grdchk fail so far
1377      - tlm. grdchk OK
1378      - checked tapelev/comlev recomputations: OK
1379    <<<checkpoint51b_pre
1380    
1381    checkpoint51a_post
1382    o added code for biogeochemistry package
1383      - new pkgs: dic, gchem
1384      - new subroutine in ptracers
1385    o modify code for biogeo packages
1386      - in model/src and pkg/ptracers
1387    
1388    checkpoint51
1389    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1390      - autodiff, ctrl, exf, grdchk, seaice
1391      kept separate packages
1392      - cost, ecco, obcs
1393    o updating verification/internal_wave, verification/lab_sea
1394      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1395    
1396    checkpoint50i_post
1397    o Preparing next differentiable checkpoint and sync
1398      of MAIN vs. ecco-branch
1399      - 1st step: this one is differentiable
1400      - 2nd step: next(! not this) checkpoint will have updated packages
1401                  from ecco-branch)
1402    
1403    checkpoint50h_post
1404    o new package "land": provide surface BC for AIM.
1405    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1406    o AIM: use true log-P extrapolation for near surface temp (= as in
1407        F.Molteni paper) ; update aim.5l_cs output.
1408    o New variable in PARM03 for more flexible pickups
1409    o somewhat cleaned package initialisation sequence for
1410      ctrl/ cost/ ecco/ in packages_... routines
1411    
1412    checkpoint50g_post
1413    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1414      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1415      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1416        made the default because of faster convergence than ADI
1417    
1418    checkpoint50f_post
1419    o exf totally restructured
1420      - replaced all exf_set_ routines by one generic exf_set_gen.F
1421        and made sure it's still differentiable
1422      - split exf_getffields.F into new exf_bulkformulae.F
1423      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1424      - updated adjoint/makefile and relevant verif. accordingly
1425    
1426    checkpoint50f_pre

1434     o removed lots of single quotes from comments
1435    
1436    checkpoint50e_post
1437    o make KPP work with PTRACERS
1438     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1439       nearly a copy of kpp_transport_s
1440     - there is no analogue to SurfaceTendencyS, so I have to use
1441       gPtr(of the surface layer) instead
1442    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1443    checkpoint50e_pre
1444    
1445    checkpoint50d_post
1446    o change kpp output from multiple-record state files to single-record state
1447      files analogous to write_state.F
1448    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1449      analogous to the cg2d-related output.
1450    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1451      so that writing to internal file fn (with length 512) fails.
1452    checkpoint50d_pre
1453    
1454    checkpoint50c_post
1455    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1456    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1457    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1458    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1459    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1460    
1461    checkpoint50c_pre
1462    Merging from release1_p13:
1463    o bug fix for pkg/seaice dynamic solver
1464    o Added SEAICE_initialHEFF to pkg/seaice
1465    
1466    checkpoint50b_post
1467    o store u*,v* in gU,V instead of in guNm1,gvNm1
1468    o in order to put the momForcing out of the Adams-Bashforth:
1469      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1470      to timestep.F
1471    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1472    o re-generate output for highly sensitive test-exp:
1473       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1474    
1475    checkpoint50b_pre
1476    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1477    o corrected CPP option mismatch in exf_Bulk... functions for case
1478      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1479    
1480    checkpoint50a_post
1481    o Bug fix for merging between c50 and KPP.
1482      ikey was passed from thermodynamics to kpp_calc via
1483      common block rather than being recomputed in kpp_calc,
1484      in contradiction with new key itdkey.
1485      New key ikppkey created, and tamc.h headers updated.
1486    
1487    checkpoint50
1488    - 2nd step of merge with ecco-branch:
1489      merge changes in ecco-branch back into main trunk
1490    - bug fix in find_alpha
1491    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1492    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1493    - merged some sliced AD support routines
1494    
1495    checkpoint49
1496    merged from ecco-branch:
1497    o exf:
1498      - Enable initialisation of forcing fields to constant
1499        (runtime) values.
1500      - in exf_getffields.F
1501        Reduce i-/j-loop to interior domain, discarding overlaps.
1502        That also fixes wrong TAF-key computations for key_1, key_2
1503        with bulf formulae.
1504      - exf_init.F modify #ifdef for exf_init_evap
1505      - exf_getffieldrec.F, ctrl_getrec.F
1506        The following INT-usages are not safe:
1507          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1508          fldcount = int(fldsecs/fldperiod) + 1
1509        and were modified.
1510    o autodiff: checkpoint_lev...
1511      - updated storing for bulk formulae (some arrays were missing)
1512      - added state for seaice package
1513      - synchronized with main branch
1514    o DIVA:
1515      Modif.s in
1516      - the_main_loop.F
1517      - the_model_main.F
1518      and added cost_final_restore.F cost_final_store.F
1519      o With these changes, it is possible to fully separate
1520        the first forward run to compute the cost function (mdthe_main_loop)
1521        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1522        into separate model executions.
1523        This enables better tuning of DIVA to given queue sizes.
1524      o Loss of cost function value in consecutive DIVA runs is
1525        fixed by storing to 'costfinal' file.
1526      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1527        beginning/end of adjoint integration is accounted for.
1528      The current changes apply to TAF-1.4.26.
1529      TAF has one remaining bug, requiring one manual change
1530      (see MITgcm manual).
1531    o cal: synchronized between MAIN and ecco-branch
1532    
1533    checkpoint48i_post
1534    o Changes to restore differentiability of code w.r.t. previous tag
1535      (mostly adding new routines to make list and replacing
1536      pressure by totPhiHyd).
1537    o Updated and merged grdchk package
1538      - has both ADM and TLM checks
1539      - works for single- and multi-proc.
1540      - output cleaned
1541      - worked successfully for parallel DIVA
1542    o genmake:
1543      - Adding -platform=SP4
1544      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1545    o Modif. for DIVA:
1546      ctrl_unpack should not be called in intermediate DIVA interval.
1547      (similar thing would apply for active files such as
1548      tbar, sbar, psbar, which should not be reinitialised;
1549      only relevant for ecco-branch)
1550    
1551    checkpoint48h_post
1552    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1553    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1554    o Added SEAICE_initialHEFF to pkg/seaice
1555    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1556    
1557    checkpoint48g_post
1558    --- EOS:
1559    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1560      store total Potential in totPhyHyd for diagnostics & EOS.
1561    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1562    --- Pressure/geopotential gradient:
1563    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1564    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1565      ( changes results of global_ocean_pressure )
1566    o NLFS + z-coord.: add eta*Rho' contribution.
1567    o accurate phiHyd when using interface-W at the middle between 2 centers
1568     ( changes results of ideal_2D_oce )
1569    o includes r* 2nd term in potential gradient.
1570    
1571    checkpoint48f_post
1572    Merging from release1_p12:
1573    o Modifications for using pkg/exf with pkg/seaice
1574      - improved description of the various forcing configurations
1575      - added basic radiation bulk formulae to pkg/exf
1576      - units/sign fix for evap computation in exf_getffields.F
1577      - updated verification/global_with_exf/results/output.txt
1578    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1579      (SBO) core products, including oceanic mass, center-of-mass,
1580      angular, and bottom pressure (see pkg/sbo/README.sbo).
1581    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1582      to avoid negative values in shallow regions.
1583      - updated verification/natl_box/results/output.txt
1584      - updated verification/lab_sea/results/output.txt
1585    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1586    o Added useSingleCpuIO option (see PARAMS.h).
1587    o Updated useSingleCpuIO option in mdsio_writefield.F to
1588      work with multi-field files, e.g., for single-file pickup.
1589    o pkg/seaice:
1590      - bug fix in growth.F: QNET for no shortwave case
1591      - added HeffFile for specifying initial sea-ice thickness
1592      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1593    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1594      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1595    o pkg/seaice:
1596      - adjoint-friendly modifications
1597      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1598    
1599    checkpoint48e_post
1600    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1601    o dynamics: change definition of computational domain & adapt mom_fluxform
1602      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1603    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1604        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1605        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1606        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1607        inverted_barometer solid-body.cs-32x32x1
1608      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1609    
1610    checkpoint48d_post
1611    o in preparation for r*:
1612     a) use pre-computed gradient of hydrostatic potential:
1613        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1614     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1615        => affects results of glob_oce_pressure (different truncation error)  
1616      update output.txt of ideal_2D_oce & global_ocean_pressure
1617    
1618    checkpoint48d_pre
1619    o in preparation for r*:
1620      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1621      pass the 2 comp. of the grad. as arguments to momentum S/R.
1622      but for the moment, only used if it does not change the results.
1623    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1624    
1625    checkpoint48c_post
1626    Modifications in treatment of initial flux forcing controls
1627    to avoid extra storing of flux fields.
1628    
1629    checkpoint48c_pre
1630    o Added tidal_basin_2d experiment (currently 1D!)
1631    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1632    
1633    checkpoint48b_post
1634    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1635     (modification to pressure gradient not yet implemented)
1636    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1637      (for U & V) that are used for vertical advection of momentum.
1638    
1639    checkpoint48a_post
1640    o In preparation for r*, use temp. array to compute vertical transport
1641       in flux-form momentum pkg. => change results of few test-exp.
1642      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1643                        lab_sea, natl_box & plume_on_slope
1644    
1645    checkpoint48
1646    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1647    
1648    checkpoint47j_post
1649    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1650    o moved adexch from forward_step to addummy_in_stepping
1651    o added exch in ctrl_map_...
1652    o aveFreq.=0. at end of cost_final to avoid overwrite in
1653      reverse checkpointing loop
1654    o Yet more changes in gmredi:
1655      * adgmredi_calc_tensor
1656        avoiding all recomputation of gmredi_slope_limit
1657      * adgmredi_x/y/rtransport
1658        added flag for excessive storing to avoid recomp. of
1659        u/v/rtans, dTdx/y/z
1660        -> this is not really necessary and very memory-consuming
1661      * adgmredi_slope_psi:
1662        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1663      * gmredi_slope_limit
1664        re-activated full calculation of taperfct for case 'ac02'
1665    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1666    
1667    checkpoint47i_post
1668    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1669    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1670      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1671    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1672    o gmredi: fix few bugs.
1673    
1674    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1675    This will be a good checkpoint to plug into the ecco-branch.
1676    o few modif.'s to get latest version adjointed
1677      (mainly kick out code in ini_linear_phisurf)
1678    o modif's to run adjoint with exactConserv
1679    o case GM_BOLUS_ADVEC should be cleaned
1680      S/R gmredi_slope_psi should be cleaned
1681    o verification/carbon now has exactConserv=.TRUE.
1682    
1683    checkpoint47g_post
1684    o time-average AIM output: becomes independent from statvars time-average
1685      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1686    o After TAF bug fix:
1687      Tested adjoint of gmredi package.
1688      Tests were done with checkpoint47 rather than with latest
1689      checkpoint47f_post since the latter is broken for the adjoint
1690      verification/carbon/ contains both ADM and TLM gradient checks.
1691    Here they are, before they get changed/lost/stolen.
1692    Mostly modif.'s to fix numerical sensitivities.
1693    Gradient checks OK for
1694    - GM_taper_scheme:
1695      * clipping
1696      * ac02
1697      * linear
1698      * glw91
1699      * dm95
1700      * ldd97
1701    - GMREDI_OPTIONS:
1702      * GM_VISBECK_VARIABLE_K
1703      * GM_NON_UNITY_DIAGONAL
1704      * GM_EXTRA_DIAGONAL
1705      * GM_BOLUS_ADVEC
1706    in conjunction with data.gmredi parameters to be checked in
1707    in a few minutes under verification/carbon/code/
1708    
1709    checkpoint47f_post
1710    Merging from release1_p10:
1711    o modifications for using pkg/exf with pkg/seaice
1712      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1713        and SEAICE_EXTERNAL_FLUXES
1714      - pkg/exf CPP options EXF_READ_EVAP and
1715        EXF_NO_BULK_COMPUTATIONS
1716      - usage examples are Experiments 8 and 9 in
1717        verification/lab_sea/README
1718      - verification/lab_sea default experiment now uses
1719        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1720    
1721    checkpoint47e_post
1722    o created a tag prior to creating a branch
1723    
1724    checkpoint47d_post
1725    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1726      at the bottom boundary had an erroneous half slip boundary condition
1727    o added bottom drag and no slip boundary condition capabilities to
1728      oceanic pressure coordinates code
1729    o added new verification experiment global_ocean_pressure, this experiment is
1730      also described in the tutorial section of the manual
1731    checkpoint47d_pre
1732    
1733    checkpoint47c_post
1734    o Added a verification experiment for a global cubed-sphere ocean run
1735      -  verification/global_ocean.cubed32x32x30
1736      -  uses pkg/therm_seaice and pkg/bulk_forcing
1737    
1738    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1739    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1740      when using P-coordinate; only implemented for atmospheric config.
1741    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1742      NOTES: requires option NONLIN_FRSURF to be "#define".
1743    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1744    
1745    checkpoint47b_post
1746    Merging from release1_p9:
1747    o pkg/seaice
1748      - removed GOTO's and added taf directives
1749      - double precision constants to reduce the g77 (Linux)
1750        to F77 (SGI) differences reported in release1_p8
1751    o tools/genmake
1752      - added SGI options
1753    o verification/testscript
1754      - updated to that of checkpoint47a_post
1755    o verification/global_ocean.90x40x15/input/eedata
1756      - modified for SGI f77 compatibility
1757    o verification/lab_sea
1758      - added description of sea-ice model
1759      - added missing matlab routines
1760      - added test of thermodynamics parallelization
1761    
1762    checkpoint47a_post
1763    o new pkg: aim_v23
1764     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1765       for now, keep the same surface forcing as before.
1766     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1767     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1768     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1769    o add diagnostic of surface correction term in monitor output
1770    
1771    o bulk_force and therm_seaice
1772    - Two packages:  bulk_force (Bulk forcing)
1773      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1774    - Earlier integration from Stephaine Dutkiewicz
1775      and Patrick Heimbach.
1776    - Two ifdef statements for compile time,
1777       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1778    
1779    checkpoint47
1780    differentiable version of checkpoint46n_post
1781    o bug fix in quasihydrostaticterms
1782    o * "clean" adjoint code (in terms of extensive recomputations)
1783        can now be obtained for all GMREDI options (i.e. for
1784        - GM_VISBECK_VARIABLE_K
1785        - GM_NON_UNITY_DIAGONAL
1786        - GM_EXTRA_DIAGONAL
1787        - GM_BOLUS_ADVEC )
1788      * However, wrong gradient check problem remains unsolved.
1789      * New CPP options have been introduced for different
1790        tapering schemes
1791    o external_fields_load now part of differentiation list
1792    o pressure needs multiple storing;
1793      would be nice to have store_pressure at beginning or
1794      end of forward_step, e.g. by having phiHyd global (5-dim.)
1795      (NB: pressure is needed for certain cases in find_rho,
1796      which is also invoked through convective_adjustment).
1797    o recomputations in find_rho for cases
1798     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1799    o #define ATMOSPHERIC_LOADING should be differentiable
1800    o ini_forcing shifted to begining of initialise_varia
1801    o Incorporating QNVS line search routines into MITgcm
1802      (this is separate code, and therefore not under pkg)
1803      lsopt/, optim/
1804    o Updated verification/carbon/
1805      - #define GM_VISBECK_VARIABLE_K
1806      - GM_taper_scheme    = 'ldd97'    
1807    
1808    checkpoint46n_post
1809    Merging from release1_p8:
1810    o verification/natl_box:
1811      updating new external_fields_load routine
1812    o New package: pkg/seaice
1813      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1814      The sea-ice code is based on Hibler (1979-1980).
1815      Two sea-ice dynamic solvers, ADI and LSR, are included.
1816      In addition to computing prognostic sea-ice variables and diagnosing
1817      the forcing/external data fields that drive the ocean model,
1818      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1819      The implied surface heat flux is then stored in variable
1820      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1821      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1822      non-local transport term.  Because this call precedes model
1823      thermodynamics, temperature under sea-ice may not be "exactly" at
1824      the freezing point by the time theta is dumped or time-averaged.
1825      N.B.: fairly large differences in accuracy occur across
1826            different platforms/compilers; comparison between
1827            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1828            generated output gives:
1829       T           S           U           V
1830      C D M    c        m  s        m  s        m  s        m  s

1834    
1835      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1836    o GAD:
1837      - generated new common blocks to account for call of
1838        same gad routines with differing traceridentities
1839        (needed to modify tracerIdentity indices in GAD.h)
1840      - generated separate common blocks for case useCubedSphereExchange
1841        (Department of Futurology)
1842      - parameter lists to gmredi_?transport: added tracerIdentity
1843      - added new key indices to tamc.h
1844    o external_fields_load:
1845      - added this routine to TAF list
1846      - needed to make some common blocks global and additional storing
1847        along the same lines as exf package (checkpoint_lev?_directives.h)
1848    o exf:
1849      updated external forcing package
1850      - bug fixes carried over from ecco-branch
1851        (missing OBCS_OPTIONS.h in two routines)
1852      - enable easy to use "no forcing".
1853      - added exf I/O for atmospheric loading
1854      - added exf I/O for runoff data
1855      - transfered scaling between exf <-> MITgcm to exf namelist
1856    o Adding new verification experiment global_with_exf.
1857      This verification experiment is almost identical to the
1858      global_ocean.90x40x15 experiment, except that it uses
1859      the exf (and cal) package instead of the
1860      external_fields_load routine (cf README file).
1861    
1862    checkpoint46m_post
1863    o modified testscript to return -- when there are no lines of "%MON" output
1864    o added new flag "quasiHydrostatic" for QH mode
1865      and new routine quasihydrostaticterms()
1866    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1867      New routine: mom_u_coriolis_nh()
1868    o fixed sign of non-hydrostatic metric terms in u and v equations.
1869      Depend on correct sign of gravitySign.
1870    o added work.pc* to .cvsignore in aim directories using ifc
1871    o introduced flag for controllin non-hydrostatic metric terms
1872    o removed gravitySign from PARM04
1873    o switched to g77/ifc from pgf77 in aim experiments
1874    
1875    checkpoint46l_post
1876    o made convective adjustment work with pressure coordinates:
1877     - changed the direction of k-loop in convective_adjustment.F for the
1878       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1879     - adjusted the reference pressure k-index in convective_adjustment.F
1880     - adjusted the convection condition in convect.F (in analogy to
1881       calc_ivdc.F)
1882     - convective_adjustment no longer computes anything on the halos
1883     - removed the warnings about negative salinity from find_rho.F and
1884       find_alpha.F; instead the new routine look_for_neg_salinity, called
1885       at the beginning of find_rho, find_alpha, and find_beta, does a
1886       check of the entire slice, if CPP-option
1887       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1888    checkpoint46l_pre
1889    
1890    checkpoint46k_post
1891    o fixed the verification/global_ocean.90x40x15 experiment:
1892     - new bathymetry (the world according to A., JMC, and M.)
1893     - new initial fields and forcing fields (*.bin files)
1894     - new POLY3.COEFFS (for the next release one should switch to a full
1895       equation of state: JMD95P or MDJWF)
1896     - fixed several errors and redundancies in the data file
1897     - experiment uses looped cells
1898     - added matlab directory with diagnostic scripts for plotting of output
1899    
1900    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1901     - read AIM physics parameters from a file (data.aimphys)
1902     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1903    
1904    checkpoint46j_post
1905    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1906    o move wVel computation at the end of the time step, in S/R integr_continuity
1907    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1908    o update timeave pkg for wVel diagnostic.
1909    checkpoint46j_pre
1910    
1911    checkpoint46i_post
1912    o Clean up AIM package (and keep the results unchanged):
1913      include CPP_OPTION and use IMPLICT NONE in all routines ;
1914      declare all the variables _RL ; use _d 0 for all numerical constants.
1915      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1916    
1917    checkpoint46h_post
1918    o cleaned up the use of rhoNil and rhoConst.
1919      - rhoNil should only appear in the LINEAR equation of state, everywhere
1920        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1921        and the dynamical equations are all divided by rhoConst
1922    o introduced new parameter rhoConstFresh, a reference density of fresh
1923      water, to remove the fresh water flux's dependence on rhoNil. The default
1924      value is 999.8 kg/m^3
1925    o cleanup up external_forcing.F and external_forcing_surf.F
1926      - can now be used by both OCEANIC and OCEANICP
1927    checkpoint46h_pre
1928    
1929     Added code to convert surface volume flux (fresh water) into
1930     a mass flux when using P coordinates in the ocean (OCEANICP).
1931     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1932    
1933    checkpoint46g_post
1934    o Include a new diagnostic variable phiHydLow for the ocean model
1935      - in z-coordinates, it is the bottom pressure anomaly
1936      - in p-coordinates, it is the sea surface elevation
1937      - in both cases, these variable have global drift, reflecting the mass
1938        drift in z-coordinates and the volume drift in p-coordinates
1939      - included time averaging for phiHydLow, be aware of the drift!
1940    o depth-dependent computation of Bo_surf for pressure coordinates
1941      in the ocean (buoyancyRelation='OCEANICP')
1942      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1943        Theta, Salinity, and Pressure in the parameter list. This routine is
1944        presently contained in find_rho.F. This routine does not give the
1945        correct density for 'POLY3', which would be a z-dependent reference
1946        density.
1947    o cleaned up find_rho
1948      - removed obsolete 'eqn' from the parameter list.
1949    o added two new verification experiments: gop and goz
1950      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1951    checkpoint46g_pre
1952    
1953    checkpoint46f_post
1954    o Enable tangent linear (forward mode) gradient checks:
1955      - extended active file handling to g_... files
1956      - added TANGENT_SIMULATION to theSimulationMode
1957      - extended grdchk package accordingly
1958    o added tangent linear setup in verification/carbon/code_ftl
1959    o added adjoint setup in verification/front_relax/code_ad
1960    
1961    checkpoint46e_post
1962    o Added new equation of state -> MDJWF
1963      - EOS of McDougall et al., 2002, JAOT, submitted
1964      - caveat: the equation of state is only valid for a smaller (more
1965        realistic?) range of values than JMD95P/Z and UNESCO
1966      - added masks to the calculation of pressure in store_pressure
1967      - added more check values for density in check_eos (ini_eos.F), some of
1968        the old check values are out of the range of the MDJWF-eos, so don't
1969        expect perfect matches for those
1970    checkpoint46e_pre
1971    
1972    checkpoint46d_post
1973    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1974      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1975      case of pressure coordinates. eosType='JMD95Z' in
1976      combination with buoyancyRelation='OCEANICP' now causes an error.
1977    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1978      in find_alpha/beta.
1979    checkpoint46d_pre
1980    
1981    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1982      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1983    
1984    checkpoint46c_post
1985    o Changes necessary for ocean in p-coordinates
1986     -  Added new buoyancy relation = 'OCEANICP'
1987     -  Added new parameters = gravitySign (this used to be contained inside
1988        the factor dRdZ which I added when we first switched to R coordinates).
1989     X GM/Redi is not compatible (yet)
1990     X bottom drag and no-slip need to be debugged.
1991    checkpoint46c_pre
1992    
1993    checkpoint46b_post
1994    o Added new equation of state -> JMD95Z and JMD95P
1995      - EOS of Jackett and McDougall, 1995, JAOT
1996      - moved all EOS parameters into EOS.h
1997      - new routines ini_eos.F, store_pressure.F
1998    o Added UNESCO EOS, but not recommended because it requires
1999      in-situ temperature (see JMD95)
2000    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2001      unesco.f to be used with POLY3
2002    checkpoint46b_pre
2003    
2004    checkpoint46a_post
2005    o Added (atmospheric) pressure loading
2006      - new field in FFIELDS.h, etc...
2007      - new cpp flag ATMOSPHERIC_LOADING
2008    o Changed hFacC to _hFacC in calc_phi_hyd.F
2009    o Added SHORTWAVE_HEATING to some files for consistency
2010    checkpoint46a_pre
2011    
2012    checkpoint46

2019      - Compatible with new ctrl package
2020      - added Eliassen Palm cost hooks
2021      - modif's of existing cost functions
2022    o Adjoint-related bug fixes in kpp:

2038    
2039    checkpoint45d_post
2040    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2041    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2042      (affects plume_on_slope "cg2d" output)
2043    o add new parameter deltaTfreesurf for free-surface time stepping
2044    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2045    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B

2047    o add new flags:
2048     - T,S forcing inside/outside Adams-Bashforth

2064    o included CPP option SINGLE_LAYER_MODE in thermodynamics
2065      to configure barotropic setup (Martin Losch)
2066    o moved some initialisations within bi,bj loop in dynamics
2067      (TAF flow dependency)
2068    o in initialise_varia, moved call packages_init_variables
2069      before convective_adjustment_init
2070      (corresponding adjustment of TAF tape initialisation).
2071    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
2072    
2073    checkpoint45a_post
2074    o compute Rho over the whole domain (extend iMin,jMin indices)
2075    o specific exchange for X-slice domain (case Ny=1)
2076    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
2077    o solve_for_pressure : set cg2d_x to zero where OBCS are applied

2098    
2099    checkpoint44g_post
2100    o fix surface correction term in multiDimAdvection (affects plume_on_slope
2101      results) ; ifdef missing in thermodynamics.F
2102    
2103    checkpoint44f_pre,checkpoint44f_post

2111      + Not implemented so far:
2112        - KPP
2113        - OBCS
2114      + No specific example supplied (yet) but global_ocean.90x40x15 has the
2115        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
2116        line in data.pkg.
2117      + This package is disabled by default since it increases storage.
2118    
2119
