4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o Non-Hydrostatic:
8     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
9     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
10    o Allow to apply AB on T,S rather than on AB(gT,gS):
11     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
12     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
13       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
14     - need a "clever" read_pickup to restart from the other AB formulation
15    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
16    o remove some unused variables (reduces number of compiler warnings)
17    
18    checkpoint57w_post
19    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
20                 fix the singleCpuIO RS version of MDSWRITEFIELD
21       and add a WARNING if using globalFiles=T with multi-processors.
22    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
23      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
24    o tracer advection scheme:
25      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
26       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
27       was not very convenient).
28      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
29       (further tests needed for the implicit DST & Flux-Limiter schemes).
30    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
31      and sRef for convenience, handy, when you want to initialize
32      ptracers in a large domain with a constant non-zero value. Also,
33      untangle ptracers_init.F a little.
34    
35    checkpoint57v_post
36    o change dome exp. to use variable viscosity in side-drag terms.
37    o remove all the files from the cfc_offline test since they are now
38      incorporated into tutorial_cfc_offline which has been producing
39      identical results for a few days of testing
40    o add new parameter: sideDragFactor to enable half-slip-side BC
41      and change side-drag S/R to use viscosity from mom_calc_visc
42      (can switch back by setting sideDragFactor=0.); affects results at
43      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
44       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
45    o vorticity & strain are now computed without masking, to account for
46      no-slip-side BC in variable viscosity calculation ; mask is applied
47      anyway later on, before computing advection/coriolis terms.
48    o modify exp4 to test new obcs support for reading from external files
49      and for passive tracers
50    o fix behavior of ptracers_monitor when monitor output is written to a
51      netcdf-file; still not independent of monitor.F (writes in the same
52      file).
53    o change default value of tRef (put a uniform, meaningful value for ocean
54      & atmos) and initialize sRef (was missing, as Martin mentioned).
55    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
56      to be proportional to enstrophy dissipation length.  Thus,
57       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
58      This is now consistent with Smagorinsky and with the manual.
59    
60    checkpoint57u_post
61    o OBCS and PTRACERS: add open boundary support for passive tracers
62      - either use homogenous (pseudo) v.Neumann conditions or prescribe
63        OB-values from file; this is not different from the way theta and salinity
64        are treated
65      - however, Orlanski-radiation conditions are not supported, and the model
66        will stop if you use pTracers and Orlanski at the same time.
67      - beefed up the rountine obcs_external_fields_load: now only those open
68        boundary values are overwritten with values from files for which there
69        are really files, otherwise the OB-fields remain untouched. This makes
70        it possible to use different OBs at different ends of the domain (as
71        with EXF)
72    o reduce number of exch calls in shap_filt (s2).
73    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
74      truncation level) 4/5 MLAdjust test results (11&12 digits match).
75    
76    checkpoint57t_post
77    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
78    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
79      same truncation, independent of the face number: affects affects several
80      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
81    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
82      note that biharmonic viscosity + no-slip was not tested in any experiment.
83    o fix bug in non-linear free-surf side-drag ; generate new output for
84      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
85    o make mnc honor the writeBinaryPrec flag for most kinds of output
86    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
87    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
88      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
89    o add brackets in multi-terms sum to get same truncation, independent of
90      the face number (manage to get exactly same value of gU,gV at the cs-edge)
91      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
92    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
93      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
94      a maximum grid-scale Reynolds number.  Also, changes all length calculations
95      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
96      Suggested values of viscosity parameters found in mom_calc_visc.
97      Many new viscosity diagnostics available.
98    
99    checkpoint57s_post
100    o Add clearing-house for viscosity calculations, mom_calc_visc and
101      correct numerous bugs in LeithD and Smagorinsky discretizations.  
102      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
103      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
104      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
105      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
106      The Strain-Tension form is now called with useStrainTensonVisc=.true.
107      ViscAhStrain and viscAhTension are now retired.
108    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
109    o In response to JMC's bug report, genmake2 now ignores any soft-links
110      that it finds in the *current* directory when searching for files.
111      Soft-links found in any other source directories will still work as
112      they did before.
113    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
114      a C routine to unlimit the stack size
115    o mnc-ify pkg/aim snapshot vars
116    o mnc-ify pkg/land as requested by Daniel
117    o various changes to mnc including:
118      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
119      - output can now be grouped so that all files within a group
120          change the ITER portion of their names in lock-step together
121      - can now read ("global") PER-FACE (in addition to PER-TILE) files
122          and works with both EXCH1 and EXCH2 (but needs more testing)
123      - writing works for all verification test cases w/ g77 on Linux
124    
125    checkpoint57r_post
126    o make MNC variable initialization happen earlier
127    o add diagnostics for (almost) each term of the momentum Eq.
128    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
129    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
130    o remove MINIMAL_TAVE_OUTPUT option ;
131      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
132    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
133      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
134    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
135    o add time-dependent SST, SSS control
136    o cost terms in ecco/ modularized (new cost_generic.F)
137    o cost_averages routines are modularized (new cost_averagesgeneric.F)
138    o new infrastructure for seaice model vs. obs misfits in seaice/
139      * driver from the_main_loop.F is seaice_cost_driver.F
140      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
141      * gradient check in Exp. 6a of natl_box_adjoint/
142    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
143      (see README file)
144    
145    checkpoint57q_post
146    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
147    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
148      - bug was reported by Jean-Michel and Ian Fenty
149    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
150      update exp. cpl_aim+ocn output.
151    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
152      Needed for high-res. runs with large global files
153      to be able to limit tapelev size
154    o Changed some tests for adjoint:
155      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
156      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
157      * global_ocean.90x40x15/ back to default 3-level checkpointing
158    o Modifications to enable scripted COMMON to MODULE conversion
159      * verification/OpenAD/code/ has necessary scripts and description;
160      * converts, compiles and runs successfully;
161    
162    checkpoint57p_post
163    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
164    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
165      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
166    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
167    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
168      (was already the case for dissipation with mom_vecinv,
169       and also the case for grad.PhiHyd when staggered-timeStep)
170      This will allow to put dissipation out-off the AB time-stepping.
171     Unfortunately, affects truncation error. Update output of exp. that "fails"
172      (cg2d matching number) and leave the others for later: front_relax(10),
173      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
174      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
175    
176    checkpoint57o_post
177    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
178      (2) its ready to be documented during the 20050801 DocFest
179    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
180      for ideal_2D_oce and lab_sea on linux_ia32_g77
181    o set to #undef CTRL_SET_OLD_MAXCVARS_30
182      in global1x1_tot/code_seaice_adj to access indices 32, 33
183      (worth another tag)
184    
185    checkpoint57n_post
186    o adding precip control xx_precip 32
187    o adding swflux control xx_swflux 33
188    o Replacing 10 forcing penalty cost routines by 1 generic.
189    o Implementing partitioning in time-mean and variable adjustment
190      for atmos. state.
191    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
192    o in natl_box_adjoint:
193      * updated exp 1 to 10
194        (but does not have time-mean vs. variable split results yet)
195    o updated global1x1/*_seaice_adj/
196      to incorporate latest changes
197    o enable useSingleCpuIO for mdsio vector routines
198      (applies in particular to tapelev I/O)
199    o removed inefficient K-loop in all active_file*control*.F
200    
201    checkpoint57m_post
202    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
203      and advect_cs (use EXCH-2 and standard cs-32 grid files).
204    o pkg/exch2: filling of face-corner halo regions is optional
205      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
206    
207    checkpoint57l_post
208     tag before updating tutorials (pre-release-2)
209    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
210       for output and interpolation of input fields onto model grid)
211    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
212       Affects results of exp. rotating_tank ; update output.txt.
213    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
214          and taking the square quantity and/or using a fraction-weight field.
215    o fix aim_diagnostics_init.F mate numbers.
216    o add mnc output capability to diagnostics/diagstat and update
217      our cvsignore files for the ACSII output generated
218    
219    checkpoint57k_post
220    o lab_sea now uses diagnostics package and provides a suite of
221      new EXF diagnostics output.
222    
223    checkpoint57j_post
224    o exf
225      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
226        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
227        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
228      * extended diagnostics output
229        - now includes all EXF variables
230        - hs, hl moved to common block
231        - separate S/R for diagnostics, called after ctrl vector is added
232        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
233        - EXFqnet contains true Qnet (i.e. includes qsw)
234      * updated verif. lab_sea, global_with_exf
235      * Rearranging hflux (exf_mapfields -> exf_getforcing)
236        to ensure that diagnostics sees a true EXFqnet
237    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
238    o diagnostics pkg: change pointers so that 1 diagnostic can be used
239      several times with different frequencies.
240    o mnc-ify the thsice package as requested by Daniel Enderton
241      - the monitor--MNC output needs work
242      - many attributes need to be added (most are currently blank)
243    o mnc-ify theaim_v23 package as requested by Daniel Enderton
244      - many attributes need to be added (most are currently blank)
245    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
246    o add Sadourny like discretization to the 4th.O vorticity advection scheme
247    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
248      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
249         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
250    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
251     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
252    
253    checkpoint57i_post
254    o Diagnostics package was changed: diagnostic allocation is now deactivated
255      by setting an empty file name in the namelist (used to be by setting 0 frequency)
256    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
257      add 1rst Order upwind vertical Shear.
258    o add a quick fix for A/B checkpointing in OFFLINE mode
259    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
260      end-run around the C/Fortran linking horror in eesup/src/timers.F
261    o added pkg/runclock: allows user to terminate run based on wall clock
262    o added non-hydrostatic scaling parameter: nh_am2
263    o pkg/my82: futile attempt to make results compiler-independent by adding
264      some "_d 0", etc. no effect.
265    o for mnc output, fill the 'T' coordinate var with myTime and create a
266      separate 'iter' variable for iteration count
267    o pkg/diagnostics:
268      add new capability: output of Global/Regional & per-level statistics ;
269      tested against monitor output (including land & thSIce) on various exp.
270    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
271    
272    checkpoint57h_done
273      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
274      data.diagnostics, data.gchem, data.ptracers) is done.
275    
276    o pkg/diagnostics: prepare for Global/Regional statistics.
277      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
278    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
279      and rename it: DIFFERENT_MULTIPLE
280    
281    checkpoint57h_post
282    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
283    o pkg/diagnostics: change output frequency, now in seconds (instead
284      of Nb of iterations). This requires to change data.diagnostics.
285    checkpoint57h_pre
286    
287    o in mnc, let the user create the output dir if both mnc_outdir_date
288      and mnc_outdir_num are false
289    o add fflags() to pkg/diagnostics which allows one to specify, on a
290      per-file basis, the file precision [default behavior is unchanged]
291    o added diagnostics to pkg/kpp, including computation of mixed layer
292      depth based on a temperature/density criterion
293    o updated verification/natl_box to test the new pkg/kpp diagnostics
294    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
295    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
296    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
297      not mnc -- this mistake was found by JMC and is now corrected
298    
299    checkpoint57g_post
300    o add Adams-Bashforth 3rd Order time stepping:
301      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
302      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
303    checkpoint57g_pre
304    
305    o make lambda[Theta,Salt]ClimRelax spatially varying
306      (default remains spatially uniform constant based on tau)
307    o added new control variables
308      * init. uVel, vVel, etanN
309      * lambda[Theta,Salt]ClimRelax
310    o separate masks used for ctrl_pack/unpack 'from write_grid' output
311      (suggested by G. Forget)
312    
313    checkpoint57f_post
314    o add parameter "baseTime" = model base time = time at iteration zero
315      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
316      account for baseTime shift
317    o move Coriolis arrays from PARAMS.h to GRID.h
318    checkpoint57f_pre
319    
320    o mnc-ifying the seaice package
321    o introduced an alternative length scale calculation for use in the limiting
322      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
323    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
324    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
325      as well as grad(vort3).  Made it compatible with both approximate form
326      for the cubed sphere and full form of these gradients.  Added flag
327      useFullLeith to select between approximate and full form.  
328    o add "d0" in getcon.F to reduce differences between compilers/platforms
329      update output.txt of exp. fizhi-gridalt-hs
330    o change port_rand funtion to allow to set the seed.
331    o fix obscure MNC bug involving conversion between reals and integers
332      - it caused no problems with certain (eg. gcc, ifc) compilers but the
333        new version is now more standards-compliant
334    o adjoint-related modifications
335      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
336      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
337      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
338    
339    checkpoint57e_post
340    o Adding eddy stress controls a la Ferreira et al.
341    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
342    
343    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
344      update output.txt of exp. fizhi-gridalt-hs
345    o add more "Z" dimensions and associated coordinate vars to MNC
346    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
347    o parameter calendarDumps: when set, approximate months (30-31 days) and years
348      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
349      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
350      months and years.  Requires pkg/cal.
351    o diagnostics: add pickup functionality
352      - off by default for backwards compatibility
353      - current version only uses MDSIO -- MNC will be added
354    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
355    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
356    
357    checkpoint57d_post
358    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
359    o modify verification/ideal_2D_oce so that it tests the creation of mnc
360      output from the diagnostics package
361    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
362    o make genmake2 more portable by using ".$FS" instead of ".f" for more
363      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
364    o add coordinate variables to the MNC output from the diagnostics package
365    o change MNC-flags default value: true when useMNC=TRUE
366    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
367      the ability (off by default) to read the grid information using MNC
368    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
369    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
370    o do snap-shot diagnostics at the middle of the time-interval (instead of
371      at the end).
372    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
373      new test for AIM with thSIce + slab-ocean
374    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
375    o move state variable diagnostics to the beginning of the time step ;
376      (note: still needs some work specially for snap-shot diagnostics)
377      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
378    
379    checkpoint57c_post
380    o Change testing option (-ieee) to get closer agreement between g77 & ifort
381    o generate new output.txt files on faulks with g77 & the new -ieee option
382    checkpoint57c_pre
383    
384    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
385      update output.txt of exp. global_ocean.90x40x15
386    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
387      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
388    o add saltFlux(+File) forcing capability with periodicExternalForcing
389    o allow to use pkg diagnostics for GM-Redi & ThSIce output
390    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
391    o improvements for the MNC output from DIAGNOSTICS:
392      - correct handling of the unlimitied dimension
393      - all dims now have associated coordinate variables
394      - variables located at U, V, and Corner ("Z") points are now written
395        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
396        *all* data points are output
397    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
398    o added pkg/seaice/seaice_monitor.F
399    o mdsio_readfield.F can now read files visible only to master MPI process.
400    o pkg/seaice: some test code for ice-modified ocean stress
401    o exf_getffields interpolation defaults to bilinear for all scalar forcing
402      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
403      spurious negative numbers for precipitation and humidity.  Will cause
404      some small numerical differences for integrations using pkg/exf/exf_interp.F.
405    o pkg/ctrl/
406      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
407        May be enabled via doPackDiag
408      *  introduce z-scaling of
409         + gradient (doZscalePack) and
410         + control (doZscaleUnpack)
411    o pkg/mdsio/
412      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
413      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
414    
415    checkpoint57b_post
416    o simplify options in diagnostics_fill arguments (remove weird combinations)
417    o fix MNC coordinate variables so that they now contain per-face index
418      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
419      general, EXCH2 grids are only aligned to a "local" coordinate system
420    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
421    o Implement instantaneous output within pkg diagnostics:
422      setting a negative frequency in data.diagnostics produces
423     "snap-shot" output (as opposed to time-average if freq > 0)
424    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
425      NOTE: change ptracer diagnostics name: use 2 characters to work with
426            more than 9 tracers. Add also diagnostics of advect & diffus flux.
427    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
428      becomes the coordinate variable for the 'T' dimension
429    o add CF-style coordinate variables to MNC
430      - just a first cut:  numbers are meaningless on the cubesphere and
431        missing along the T axis but otherwise it works!
432    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
433    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
434    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
435      this is based directly on what the model compute, so that the content of
436      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
437    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
438    o clean up build options files for SunOS, in particular
439      - remove -traditional from xmakedepend
440      - change -xarch=v9 to -xarch=native for f77
441      - restore use of make (not gmake)
442      - add CC=gcc if using g77
443    o changes per discussion of AM, JMC, & EH3 today:
444      - move redundant "grid" variables out of "state" -- in preparation of
445        creating proper CF-style coordinate variables and in recognition
446        that any/all grid variables can be easily copied (eg. w/NCO) from
447        the grid files into any of the other NetCDF files
448      - *always* output grid variables with MDSIO (this will eventually be
449        changed)
450      - output MNC grid file if useMNC is true
451    o every instance of _END_MASTER() has been found and replaced with
452      _END_MASTER( myThid ) in order to satisfy certain picky Sun
453      preprocessors
454    o re-arrange diagnostics pkg initialisation:
455     - allow each package to extend the available diagnostics list
456     - add some checking and fix small problems (multi-threaded, ...)
457     - new S/R diagnostics_fill (replace fill_diagnostics):
458       look through the short list of active diag. (instead of the long list)
459       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
460    
461    checkpoint57a_post
462    o this set of changes restores TAMC compatibility
463      tested for global_ocean.90x40x15 adjoint on trough
464      (what a pain)
465    
466    checkpoint57a_pre
467    o some modifs in tools/build_options for sunos
468    o call ctrl_pack for ctrl at end for optimcycle=0
469    
470    checkpoint57
471    o add horizontal bi-harmonic viscosity for vertical velocity
472      - new parameter viscA4W (defaults to viscA4)
473      - affects only non-hydrostatic code
474      - to be done: no-slip lateral boundary conditions
475    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
476    o implement Implicit Vertical advection for pTracers
477    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
478      (implemented also for implicit vertical diffusion & advection)
479    o OBCS: extend application of tracer open boundary conditions
480      to a strip beyond the boundary of width Olx/Oly
481    o add call monitor to TAF set of required calls (flow directives)
482      and include in natl_box_adjoint
483    o untangle a few ifdefs related to cost, ctrl, autodiff
484      untangel a few ALLOW_ECCO_OPTIMIZATION
485    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
486      (theta2, salt2 in ecco_cost_weights)
487    
488    checkpoint56c_post
489    o OBCS as control variables
490      - update ctrl_ad_diff.list, obcs_ad_diff.list
491      - remove balance of obcs controls from default
492      - fix index bug nobcs in ctrl_init
493      - fix dummy fields filen in ctrl_pack
494      - add dummy weights for obcs
495    o lsopt: comment out fort.94 output
496    o optim:
497      - remove unnecessary header files
498      - adjusted namelists
499      - add xerbla.F to Makefile
500    o exf:
501      - multiple modifications of exf_check_range
502      - unit change in exf_init_runoff from [m/year] to [m/s]
503    o mdsio:
504      - i/o-vector change debugLevel from debLevA to debLevB
505    
506    checkpoint56b_post
507    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
508      is called from DO_THE_MODEL_IO
509      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
510      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
511      - clean up PTRACERS_WRITE_TIMEAVE a little
512    o add another verification experiment that tests both the cfc-pkg and
513      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
514      reactive tendencies treated inline with regular timestepping
515    o testreport previously did a lousy job of comparing small numbers, so
516      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
517      implemented in the little c-progam tmp_cmpnum.c which is embedded in
518      testreport.
519    o ptracers_monitor: bug fix for MPI
520    
521    checkpoint56a_post
522    o GCHEM: finish reorganizating the package
523      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
524        (introduces another 3D-array for each passive tracer, but only if
525        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
526        gchemTendency is not needed because the timestep is done separately)
527      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
528      - GCHEM is now---more or less cleanly---separate from PTRACERS
529      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
530        so clear to me how that should be done in a general way.
531    o CFC: improve formatting of output in CFC_ATMOS
532    o PTRACERS:
533      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
534        that ALL experiments with ptracers enable can be checked. This makes
535        GCHEM_MONITOR obsolete.
536      - include a runtime parameter PTRACERS_monitorFreq that defaults to
537        monitorFreq
538      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
539    o add PTRACERS (PTR0[1-5]) to testreport output
540    o exf_check_range:
541      * default changed to .TRUE.
542      * will check values for niter0 if debLevA, every timestep if debLevB
543      * STOP in exf_check_range if 'out of range'
544      * range chosen generous to allow for potential extema
545      TBD: a version with stricter range
546           permitted range would be runtime parameters
547    o GMredi:
548      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
549      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
550      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
551    o GCHEM:
552      - move call to GCHEM_FORCING_SEP, so that it is now called before
553        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
554      - introduced a useGCHEM runtime flag and applied it everywhere.
555      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
556        this flag is now only visible within GCHEM-pkg routines.
557      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
558        be replaced by a 3D array that is computed before thermodynamics; for
559        this, the tracer ID iTracer had to be included into the parameter list
560        of ptracers_forcing
561      - set up forward_step to call gchem_forcing, that will replace
562        gchem_forcing_int in ptracers_forcing
563      - cleaning up
564    o small cleaning of exch2: remove files that are also in eesupp/src
565    
566    checkpoint56
567    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
568    o mnc: cleanup "full" files--fixes out-of-memory problem
569    o ECCO-GODAE
570      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
571      * fully merged and updated from SIO code
572        windstress sign change affects
573        - exf_inscal_[u/v]stress
574        - sign of xx_tau[u/v] adjustments
575        - signs in cost_scat
576      * ctrl_get_gen: avoid update of tau[u/v] for first few days
577      * natl_box_adjoint updated and compressed
578      * 2-level checkpoint switch added
579        (tested in EXP. 1 of natl_box_adjoint)
580      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
581    o SVD
582      * first complete, non-hacked version for SVD calculations
583      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
584        performed via direct access files admtlm_vector.it????
585        (via ctrl_[un]pack)
586      * optimcycle is used for ARPACK iteration counter
587        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
588      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
589        and add linear transforms where necessary
590      * controls are initial/final SST, SSS (can be extended; need to check
591        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
592    o mdsio: filename info to both stderr, stdout
593    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
594      from sign change
595    
596    checkpoint55j_post
597    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
598      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
599    o add consistent build directories and .cvsignore files to verification
600    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
601    o make all subroutines 30 or less characters in length for certain older
602      compilers to work (a thorough search only turns up two routines in
603      pkg/ptracers)
604    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
605      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
606    
607    checkpoint55i_post
608    o change arrays for total vertical diffusivity (2.D if explicit,
609      3.D if implicit) ; each ptracer uses its own background value.
610    o added mnc/NetCDF output capability to ocn_compon_interf
611      - added bits to verification/cpl_aim+ocn so that it can run on
612        ITRDA and other clusters without the mpirun "-wd" option
613    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
614      configuration
615    o give MNC the ability to create additional files rather than
616      exceeding a specified file size limit "MNC_MAX_FILESIZE"
617      - the default is just less than 2GB which is a practical limit
618        on many systems
619    o Compute the non-local term using either KPP vertical diffusivity (=default)
620       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
621    
622    checkpoint55h_post
623    o add verification test "vermix"
624    o remove all the *_ioinc flags and replace with the single global
625      outputTypesInclusive flag
626    o allow to set a vertical profile of vertical diffusivity for T & S
627    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
628    o useMNC moved from data.mnc to data.pkg
629    
630    checkpoint55g_post
631    o Renaming carbon AD experiments to comply with testreport conventions
632    o Updating adjoint of Held-Suarez hs94.1x64x5
633    o Fixing directives for non-ECCO forward_step, after ECCO directives
634      have been fixed to avoid recomp. of do_oceanic_phys
635      Works well for global_ocean.90x40x15,
636      but recomp. issue remains for carbon
637    o Updating adjoint output for natl_box_adjoint after
638      pkg/ecco has been modified (see taga c55d_post)
639    
640    checkpoint55f_post
641    o rename to timeave_init_fixed
642    
643    checkpoint55e_post
644    o some delicate re-shuffle of store directives to avoid one
645      extra call of do_oceanic_physics
646      affects ecco_the_main_loop.F, do_oceanic_physics.F
647      checkpoint_lev1_directives.h
648    o NB: this may break global_ocean adjoint temporarily,
649      but it is clear how to fix it. Will do later, need this now.
650    
651    checkpoint55d_post
652    o ECCO specific cost function terms (up-to-date with 1x1 runs)
653    o ecco_cost_weights is modified to 1x1 runs
654    o modifs to allow observations to be read in as
655      single file or yearly files
656    o enable to read exf forcing fields as either
657      single file or yearly files (flag useExfYearlyFields)
658    checkpoint55d_pre
659    
660    o switch between 2-level and 3-level checkpointing
661    o add ability of MNC to write local and "partial" (eg. 2D slices where
662      the full 3D field is never actually stored) arrays to NetCDF files
663      with the correct (that is, the complete multi-dimensional) set of
664      array indicies
665      - used in mom_vecinv() to write the diagFreq output
666      - tested (demonstrated) in verification/aim.5l_cs
667    o further mnc-ification
668      - add verification/lab_sea to the list with mnc setups
669      - fix undefined mnc v-names in cd_code
670      - add kpp to mnc output (both snapshot and timeave)
671    o non-hydrostatic code
672      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
673        in calc_gw.F
674      - defaults to viscAh
675      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
676        friction or Leith) in non-hydrostatic mode, as long as there is
677        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
678    o pkg/cost
679      extend simple cost functions to treat time mean quantities
680      (T,U,V) via cost_accumulate_state from cost_tile
681    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
682        be 2 times larger than the minimum size the advection scheme requires.
683        now get a perfect conservation of salt in advect_cs test-exp (updated)
684    o GGL90 (Gaspar's TKE mixed layer)
685      - add horizontal diffusion of TKE, requires exchanges in
686        do_fields_blocking_exchanges, horizontal diffusivity is zero by
687        default. In OPA there is no horizontal diffusion of TKE but the
688        mixing coefficients are computed from a horizontal average of TKE of
689        6 points or so. I think that diffusion has a little more physical
690        justification.
691      - clean up ggl90_calc in the hope of reducing memory usage (this hope
692        was in vain)
693      - mask tke-variable in ggl90_init
694    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
695    o fix biharmonic diffusion on CS-grid.
696    o more obcs stuff
697      - added obcs_external_fields_load as an alternative to the EXF-pkg option
698        for reading boundary values. This routine is called from
699        obcs_prescribe_read
700      - updated obcs_check
701      - changed sponge layer relaxation parameter units for days to seconds
702      - turned off sponge layer by default
703      - changed argument list of OBCS_CALC to myTime+deltaTclock
704      - fixed about 35 bugs in obcs_external_fields_load
705    
706    checkpoint55c_post
707    o obcs stuff
708      - new runtime flags useOBCSprescribe, useOBCSbalance
709      - re-arranged obcs_calc
710      - moved exf_getobcs to obcs_prescibe_read
711        obcs_prescibe_read is called after ORLANSKI stuff
712        and independent of it (executable can contain all).
713      - updated obcs_check
714      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
715        These may be necessary only if tangential velocities are
716        prescribed at OB, not sure, needs testing.
717    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
718      which simplifies the calls and passes the ifc check-bounds test
719    
720    checkpoint55b_post
721    o add a 2D scalar, Z location, exchange_2 routine.
722    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
723      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
724      affects advect_cs results (for the wrong reason): update output.txt
725    o use a more standard discretization for biharmonic viscosity ;
726     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
727      affects results of dome set-up: update output.txt
728    o fix gad_advection.F (CubedSphere part), back to version 1.23
729    o fix bug in mom_vi_del2uv.F (CubedSphere part).
730    
731    checkpoint55a_post
732    o merged code to
733      * prescribe/read time-dependent open boundaries
734        (works in conjunction with exf, cal)
735      * sponge layer code for open boundaries
736      * each boundary N/S/E/W now has its own CPP option
737        (healthy for the adjoint)
738    
739    checkpoint55
740    o up-to-date adjoint of previous breaks
741      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
742      - global_ocean_ebm: adjoint still needs fix (TLM ok)
743      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
744      - carbon: * remove tr1-related adjoint verification
745                * add ptracer as control variable
746    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
747      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
748    
749    checkpoint54f_post
750    o in verification/carbin/ remove experiment related to
751      ALLOW_PASSIVE_TRACER (array tr1 etc)
752      code_ad/ input_ad/ results_ad
753    
754    o add two new packages
755      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
756        + subject to optimization (memory)
757      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
758        + subject to reordering (many GOTOs in the original code)
759        + so far opps is called for every (i,j) point, and then operates in
760          the vertical; one may want to reorder the scheme in order operate in
761          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
762          fields)
763    o overhaul of IO so that we now have flags for MDSIO and/or MNC
764      - all verification tests compile and run with linux_ia32_g77
765      - defaults are compatible with current input files--nothing
766        should change if you were not previously using MNC
767      - MNC output has been added in numerous places (eg. timeave)
768        but there are still a few writes not yet do-able with MNC
769        (this is in progress)
770      - flags now allow for either/or/both use of MDSIO and MNC and
771        documentation will soon follow
772      - numerous small formatting cleanups for ProTeX
773    o add version info (via BUILD_INFO.h) to MNC and stdout
774    
775    checkpoint54e_post
776    o add two new packages
777      - pp81 (Packanowski and Philander, 1981), Richardson number and
778        stratification dependent mixing
779      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
780      - these scheme operate in a similar manner as KPP (without ghat, of
781        course), however there is only one diffusivity that is used for both
782        temperature and salinity (and passive tracers)ç
783    o add offline package
784    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
785      provided by Stephanie Dutkiewicz
786    o genmake2: add ability to search for C compilers and cleanup test output
787      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
788    
789    checkpoint54d_post
790    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
791    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
792      leading to additional shift by 5 days each year of integration
793       (i.e. leading to considerable offset over the years)
794    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
795    o start with no AB and no initial filtering (staggerTimeStep):
796      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
797    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
798      (external loading & cpl import/export stay in forward_step.F)
799    o update coupling interface to work with new staggerTimeStep
800    o change MDSIO ptracers_pickup.
801    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
802    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
803    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
804    
805    checkpoint54c_post
806    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
807      this affects (truncation error) output.txt of test-exp:
808       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
809    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
810    o change Qnet to always be the net heat flux, (+upward).
811      affects (truncation error) output of natl_box exp.: updated
812    o define the max number of passive tracers in PTRACERS_SIZE.h
813    o start to test mnc routinely in exp0
814    o add sea-ice loading (sIceLoad) as a new forcing field.
815    
816    checkpoint54b_post
817    o add testreport "-j JOBS" option for parallel builds (tested and pretty
818       impressive on Altix and Opteron systems)
819    o diagnostics can now write NetCDF files through the mnc package
820    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
821    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
822    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
823      affects (truncation error) output of lab_sea & natl_box exp.: updated
824    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
825    
826    checkpoint54a_post
827    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
828    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
829    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
830    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
831      + internal_wave (shift in writing cg2d_ini_res)
832    checkpoint54a_pre
833    
834    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
835      - modified verification/lab_sea and natl_box_adjoint accordingly
836    
837    checkpoint54
838    checkpoint53g_post
839    o prepare splitting of thermodynamics: store convect.counter in common block
840    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
841      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
842    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
843    o new parameter "nShapS": allow to treat differently S from T (nShapT)
844    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
845    o restore adjointability
846    
847    checkpoint53f_post
848    o modifications that affect AIM experiment results (update output.txt):
849      - no advection of S at top interface Nr (pkg/generic_advdiff)
850      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
851    o AIM pkg:
852      - include stability function into surf.Flux derivative relative to Tsurf
853      - calculate clear-sky radiation & surface temp. change (for diagnostics)
854    
855    checkpoint53e_post
856    o merged cylindrical coord configuration
857    o added rotating_tank experiment
858    checkpoint53e_pre
859    
860    checkpoint53d_post
861    o faulks upgraded: re-generate output.txt that have changed:
862       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
863    o Added Bryan and Lewis, 1979, vertical diffusivity profile
864    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
865    o added Sadourny discretization of Coriolis
866      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
867      - re-enabled use of omega3 (useAbsVorticity)
868    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
869      vector-invariant equations
870      - note: does *NOT* yet use same variable visc. for no-slip BC's.
871    o recoded the lateral boundary conditions for non-hydrostatic w, this time
872      hopefully without new bugs
873      - still to do: biharmonic friction for non-hydrostatic w
874    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
875    o regenerated output for global_ocean_ebm (using -ieee)
876    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
877      of mom_common/
878      - simple re-arrangement of instructions within computing loop
879    checkpoint53d_pre
880    
881    checkpoint53c_post
882    o new version of coupler for AIM+thSIce and Ocean models
883     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
884     - land: change Evaporation of snow
885     - aim with thSIce: fix bug in snow-precip.
886    o changes to calc_gw.F
887     - bug fix for w^2 term near the bottom boundary
888     - (hopefully) improve the lateral slip boundary condtions for use with
889        partial/looped cells
890      - because the bug fix changes two verification experiments anyway (exp5
891        and plume on slope), change the lateral boundary condition from half slip
892        to the value of no_slip_sides
893    o ebm package wasnt quite up to the parallel task. Fixed that.
894    o Adjoint of EBM package + verification
895      * TLM OK
896      * ADM not sufficient accuracy yet (needs further testing)
897    
898    checkpoint53b_post
899    o Commiting new energy balance model to repository
900      * package is pkg/ebm
901      * verif. is verification/global_ocean_ebm
902      * references are in ebm_driver.F
903    C      * X. Wang, P. Stone and J. Marotzke, 1999:
904    C        Global thermohaline circulation. Part I:
905    C        Sensitivity to atmospheric moisture transport.
906    C        J. Climate 12(1), 71-82
907    C      * X. Wang, P. Stone and J. Marotzke, 1999:
908    C        Global thermohaline circulation. Part II:
909    C        Sensitivity with interactive transport.
910    C        J. Climate 12(1), 83-91
911    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
912    C        Destabilization of the thermohaline circulation
913    C        by atmospheric eddy transports.
914    C        J. Climate 7(12), 1870-1882
915    o Will need long integration testing.
916    checkpoint53b_pre
917    
918    o created pkg/mom_common in preparation for variable viscosity code
919    o renamed and split ini_mnc_io
920    o pkg/land: only liquid water can diffuse or run-off
921    o AIM using land: soil wetness availability account for snow
922    o added printMapIncludesZeros to EEPARMS namelist
923    
924    checkpoint53a_post
925    o restore TAMC compatiility for exf_constants.h
926      (no usage of _d in .h)
927    o Additional storing in KPP in an attempt to fix
928      TAMC problem with adjoint of KPP code.
929      (no success...)
930      Identical code works fine with TAF.
931    o Fixed verification/natl_box_adjoint experiments.
932      Initial conditions for Experiments 4 and 5 are now
933      set to "SEAICE_initialHEFF=0", which is more reasonable,
934      and hence gives results closer to that of Experiment 2.
935      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
936    
937    checkpoint53
938    o stable checkpoint with up to date adjoint
939      TLM tests only run for 1st grdchk at the moment. Its unclear if
940      this is a code problem or a problem with resetting code for g_
941      variables that is being autogenerated wrong.
942      Otherwise:
943       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
944       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
945         are both still in chaos following their security messes.
946    
947    checkpoint52n_post
948    o various build (mostly genmake2) changes including:
949      - ability to build/run more easily within Cygwin and MacOS X
950      - more complicated Makefiles with a stronger dependence on Gnu Make
951    o pkg/seaice modifications
952      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
953        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
954        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
955      - changed proxy for geostrophic velocity and updated
956        verification/lab_sea/results/* accordingly
957      - removed ADI dynamic solver from pkg/seaice
958      - replaced all occurrences of 1/CSTICE or 1/CSUICE
959        they caused a segmentation fault under certain circumstances
960      - removed unused field WATR
961    o bug fix in exf-package:
962      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
963         now reflect that.
964    o small fixes in the cal-package:
965      - set reference date to first of January for the 'model'-calendar
966      - failing of cal_CheckDate in cal_FullDate now actually results in a
967        warning
968    o small modifications in exf-package to increase flexibility:
969      - change climtempfreeze from a constant to a runtime parameter that
970        is specified in data.exf_clim (default = -1.9)
971      - introduce runtime parameter windstressmax (default = 2.0) that is
972        specified in data.exf
973    o fix in pkg/thsice:
974      - update Evap (Tsf changes) to be consistent with Latent heat flux
975      - maintain snow precipitation unchanged (even if Tsf >=0).
976     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
977    
978    checkpoint52m_post
979    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
980      this does not change any of the results, because myIter=0 in swfrac always
981      lead to jwtype=2 (the default anyway), but the call makes little sense
982      as a default
983    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
984    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
985      atmospheric model (AIM) to use it ; add a "slab ocean" component.
986    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
987    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
988    o extending useSingleCpuIO option to work with new exch2 I/O format
989      - old-style, missing-tile I/O is still accessible by defining CPP
990        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
991    o monitor package can write to NetCDF files and/or STDOUT
992    o fix re-definition bug in MNC_GRID_INIT_ALL()
993    o doc/api_reference added
994      - a framework for building an API Reference Manual using all
995        the "protex" comments embedded in the code
996      - see pkg/generic_advdiff, pkg/mnc for examples
997    o MNC:
998      - make myThid the last argument for all subroutines
999      - new default for the grid files: NO halos
1000      - add useMNC and other run-time flags
1001      - separate per-file-group handling of the unlimited dimension
1002      - early initialization of MNC w/ flags read at the eeboot stage
1003        and lookup tables set in initialize_fixed
1004      - write all MNC output to a freshly-created directory
1005    o thermodynamics sea-ice (thsice) is now tested with testreport.
1006    o test exp. advect_cs: use the standard cs32 grid ; update output.
1007    o Added functionality to grdchk:
1008      pick global i,j,k position (or nearest wet) where to perform check.
1009    
1010    checkpoint52l_post
1011    o new land formulation:
1012      a) use ground enthalpy as prognostic variable to ensure exact
1013         energy conservation.
1014      b) account for water temperature and for latent heat of freezing
1015         in all processes (rain, run-off, ground storage)
1016      c) compute surface and ground temperature implicitly.
1017    o aim_v23 modification for new land model:
1018      a) Treat separately land / ocean / sea-ice surface fluxes
1019         to allow implicit computation of land & sea-ice surface temp.
1020      b) add snow precipitation.
1021    checkpoint52l_pre
1022    
1023    o fix problem (when 1 tile is empty) in min/max monitor.
1024    o fix bug in timeAve (u,vZetatave in common block)
1025    o no restoring terms under ice for pkg/seaice
1026    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1027    o bug fix for pkg/seaice pickups
1028    o change MNC call locations and add coordinate attributes
1029    o mask vorticity at the corner ; affects global_ocean.cs output
1030    o fix ini_curvilinear_grid ; test CS experiments with mpi
1031    o aim.5l_cs: modify sea-ice fraction input file ; update output
1032    o exf: Adding simple range check routine for exf fields after read
1033    
1034    checkpoint52k_post
1035    o removed top-level directory "diags"
1036      - we migrated these functions to pkg/timeave a long time ago
1037    o fixed bug introduced in pkg/monitor
1038    o accuracy ctrlprec = 32 insuffient for gradient checks using
1039      averaged fields (I/O via cost_averages)
1040      -> use ctrl.h in active_file*.F to control I/O precision.
1041    o paramter list of CALL ADTHE_MAIN_LOOP
1042    o added initial do_the_model_io to ecco
1043    o set all ...Freq to zero after cost_final
1044      taveFreq, dumpFreq, pChkptFreq
1045    o MAIN and ECCO differentiability restored
1046    
1047    checkpoint52j_post
1048    o fix nchklev in tamc.h for global_ocean...
1049    o Bringing flow and store directives up-to-date
1050    o Really weird thing!
1051      call do_the_model_io from the_main_loop with parameters
1052      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1053      TAF places a faulty re-call of initialise_varia
1054      after cost_final call which should not be there!
1055    checkpoint52j_pre
1056    
1057    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1058      error messages
1059    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1060    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1061      debug output
1062    o modfied mdsio_writefield.F to handle non-global files under exch2
1063    o update AIM Cubed-Sphere exp (aim.5l_cs):
1064      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1065    o update AIM Equatorial Channel exp:
1066      use standard aim_v23 pkg and change the SST fields to be more realistic.
1067    o globalFile now works with exch2
1068    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1069      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1070    o limit timeave output for hi-res integrations
1071    
1072    checkpoint52i_post
1073    o removed CPP_EEOPTIONS.h from verification/*/code
1074    o updated the tiling for global_ocean_pressure
1075    checkpoint52i_pre
1076    
1077    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1078      the old pkg/aim).
1079    
1080    checkpoint52h_pre
1081    o shortened offending lines in exch2_send_rx?.template
1082    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1083    o genmake2: add build & execute test for NetCDF code
1084    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1085      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1086    o added useSingleCPUIO flag to monitor.F and mon_out.F
1087    o added temporary hack for sea-ice dynamics on the cube:
1088      metric terms are ignored and it is assumed that
1089      there is no sea-ice on cube faces 1, 2, 4, and 5.
1090    
1091    checkpoint52f_post
1092    o added exch2 cube routines to pkg/exch2
1093    o modified hs94.cs-32x32x5 to use it
1094    o added new grid files to hs94.cs-32x32x5
1095    checkpoint52f_pre
1096    
1097    checkpoint52e_post
1098    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1099      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1100    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1101      to work with implicit vertical advection and AB ;
1102    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1103    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1104     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1105    checkpoint52e_pre
1106    
1107    o fix bug in impldiff when Nr=1 or Nr=2.
1108    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1109    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1110    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1111      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1112    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1113    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1114    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1115    
1116    checkpoint52d_post
1117    o re-tiled many expts to allow comparison in multi-processor mode
1118      - updated output accordingly
1119      - changed hs94.128x64x5 to use intial T from file rather than use the
1120        random number generator
1121    o add infrastructure in model routines for fizhi and gridalt packages
1122    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1123    o changes to permit hi-res, cubed-sphere, configuration
1124      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1125      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1126      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1127        of surface winds for the cube
1128      (A verification experiment, based on global_ocean.cs32x15, but with
1129       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1130       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1131       complete with example surface forcing files and matlab scripts to look
1132       at the output and compare it with that of global_ocean.cs32x15.)
1133    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1134       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1135       to conform to the common rule.
1136    o check-in the first version of the coupler + interfaces for multi-components
1137       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1138       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1139       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1140       - ocean and atmos. share the same horizontal grid (no interpolation).
1141       - exchanges between component and coupler is done in forward_step
1142    o new verification experiment, cpl_aim+ocn:
1143       coupled ocean - AIM atmosphere on cs32 grid.
1144    
1145    checkpoint52d_pre
1146    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1147    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1148    
1149    checkpoint52c_post
1150    o Fixing OPTIONS files for use of exf:
1151      - ALLOW_ECCO not needed
1152      - ECCO_CPPOPTIONS.h should not be included from
1153        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1154        as has been the case in the past
1155      - All cal/exf related options are currently set in
1156        single header file. Should remain so until we
1157        agree on a consistent new policy.
1158    o Removed all CPP options for cal package.
1159      cal has no more CPP options.
1160    o modified STOREs in GAD_ADVECTION
1161    o corrected key comp. for passkey
1162    
1163    checkpoint52b_post
1164    o new version: "thsice" of thermodynamic sea-ice pkg:
1165     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1166     - modify fluxes but do not change theta directly;
1167     - light cleaning of bulk_force pkg (still needed with thsice).
1168     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1169       + output_thsice.txt to test thsice & bulk_force pkgs.
1170    o put back grid & coriolis monitor output.
1171    checkpoint52b_pre
1172    
1173    o call "do_the_model_io" at the beginning (=> dump initial state)
1174    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1175    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1176      (need info on NUMBER_OF_PTRACERS)
1177    o missing PTRACERS headers in some routines
1178    o default tamc.h in pkg/autodiff supposed to crash
1179      to ensure proper customization
1180    
1181    checkpoint52a_post
1182    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1183      - moved surfaceTendencyTice from pkg/seaice to main code
1184      - subroutine FREEZE_SURFACE now limits only surface temperature
1185        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1186        => new output.txt for global_ocean.cs32x15 & global_with_exf
1187      - keep the old version of FREEZE for backward compatibility;
1188        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1189      - corresponding modifs for TAF directives
1190    o added surface flux output variables to TIMEAVE_STATVARS

1196    checkpoint52a_pre
1197    o some bug fixes for #undef REAL4_IS_SLOW
1198    
1199    checkpoint52 = ecco_c52_e35
1200    o after testing adjoints of checkpoint51u_post
1201    
1202    checkpoint51u_post
1203    o this is the post-merge tag of the ecco-branch
1204      (needs another clean checkout and re-testing)
1205    o various natl_box_adjoint configs and results
1206      but no input fields
1207    o obcs adjoint not yet merged!
1208    o adding ECCO global 1x1 and 2x2 degree configs
1209    o updated/extended some store directives for seaice
1210    o pkg/ecco now containes ecco-specific part of cost function
1211    o top level routines the_main_loop, forward_step
1212      supersede those in model/src/
1213      previous input data.cost now in data.ecco
1214      (new namelist ecco_cost_nml)
1215    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1216    
1217    checkpoint51t_post
1218    o this is the pre-merge tag of the ecco-branch
1219    
1220    checkpoint51s_post
1221    o cleanup: removed various obsolete #define-s
1222    o pkg/grdchk
1223      - renamed 'ph-grd 3' to 'grad-res'
1224      - merged from ecco-branch
1225        (remaining bug fixes for obcs gradient checks)
1226      - additional high-precision output for testreport
1227        (grep for 'precision_grdchk_result')
1228    
1229    checkpoint51r_post
1230    o cleaned up or removed CPP_OPTIONS.h files
1231    o updated results for some of the tests to reflect the new
1232      optfiles (-ieee: -O0 instead of -O3)
1233    
1234    checkpoint51q_post
1235    o cd_code:
1236      - moved cd_scheme.F -> cd_code_scheme.F
1237      - separate read_checkpoint from cd_code_ini_vars.F
1238      - separated cd_code part from write_checkpoint
1239      - updated AD_SOURCE, generated .flow
1240      - added CD_CODE_VARS.h to the_main_loop

1243      - pack/unpack now optional and decoupled from
1244        xx_/adxx_ I/O
1245      - ctrl_pack/unpack cleaned
1246        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1247      - confined inclusion of AD_CONFIG.h to where necessary.
1248    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1249    
1250    checkpoint51p_post
1251    o create initial cd_code package
1252      - WARNING: the initialization of fields within packages
1253        is broken because INI_FIELDS (where READ_CHECKPOINT is
1254        called) is called *before* PACKAGES_INIT_VARIABLES.
1255        This seems to be backwards since
1256        1) its important to initially zero the entire field including
1257           the "halo" region
1258        2) zeroing needs to be done *before* reading pickup info
1259           and the pickup call might or might not happen in any
1260           particular run
1261      - this needs an overhaul for R2
1262    o cleanup verification/*/code/GMREDI_OPTIONS.h

1297      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1298      - subroutine FREEZE now limits only surface temperature
1299        (this means new output.txt for global_ocean.90x40x15,
1300         global_ocean.cs32x15, and global_with_exf)
1301    o added surface flux output variables to TIMEAVE_STATVARS

1471    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1472    o AIM: use true log-P extrapolation for near surface temp (= as in
1473        F.Molteni paper) ; update aim.5l_cs output.
1474    o New variable in PARM03 for more flexible pickups
1475    o somewhat cleaned package initialisation sequence for
1476      ctrl/ cost/ ecco/ in packages_... routines
1477    
1478    checkpoint50g_post

1506     - there is no analogue to SurfaceTendencyS, so I have to use
1507       gPtr(of the surface layer) instead
1508    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1509    checkpoint50e_pre

1524    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1525    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1526    
1527    checkpoint50c_pre
1528    Merging from release1_p13:
1529    o bug fix for pkg/seaice dynamic solver
1530    o Added SEAICE_initialHEFF to pkg/seaice
1531    
1532    checkpoint50b_post
1533    o store u*,v* in gU,V instead of in guNm1,gvNm1
1534    o in order to put the momForcing out of the Adams-Bashforth:
1535      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1536      to timestep.F
1537    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1538    o re-generate output for highly sensitive test-exp:
1539       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1540    
1541    checkpoint50b_pre
1542    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1543    o corrected CPP option mismatch in exf_Bulk... functions for case
1544      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1545    
1546    checkpoint50a_post
1547    o Bug fix for merging between c50 and KPP.
1548      ikey was passed from thermodynamics to kpp_calc via
1549      common block rather than being recomputed in kpp_calc,
1550      in contradiction with new key itdkey.
1551      New key ikppkey created, and tamc.h headers updated.
1552    
1553    checkpoint50
1554    - 2nd step of merge with ecco-branch:
1555      merge changes in ecco-branch back into main trunk
1556    - bug fix in find_alpha
1557    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1558    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1559    - merged some sliced AD support routines
1560    
1561    checkpoint49
1562    merged from ecco-branch:
1563    o exf:
1564      - Enable initialisation of forcing fields to constant
1565        (runtime) values.
1566      - in exf_getffields.F
1567        Reduce i-/j-loop to interior domain, discarding overlaps.
1568        That also fixes wrong TAF-key computations for key_1, key_2
1569        with bulf formulae.
1570      - exf_init.F modify #ifdef for exf_init_evap
1571      - exf_getffieldrec.F, ctrl_getrec.F
1572        The following INT-usages are not safe:
1573          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1574          fldcount = int(fldsecs/fldperiod) + 1
1575        and were modified.
1576    o autodiff: checkpoint_lev...
1577      - updated storing for bulk formulae (some arrays were missing)
1578      - added state for seaice package
1579      - synchronized with main branch
1580    o DIVA:
1581      Modif.s in
1582      - the_main_loop.F
1583      - the_model_main.F
1584      and added cost_final_restore.F cost_final_store.F
1585      o With these changes, it is possible to fully separate
1586        the first forward run to compute the cost function (mdthe_main_loop)
1587        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1588        into separate model executions.
1589        This enables better tuning of DIVA to given queue sizes.
1590      o Loss of cost function value in consecutive DIVA runs is
1591        fixed by storing to 'costfinal' file.
1592      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1593        beginning/end of adjoint integration is accounted for.
1594      The current changes apply to TAF-1.4.26.
1595      TAF has one remaining bug, requiring one manual change
1596      (see MITgcm manual).
1597    o cal: synchronized between MAIN and ecco-branch
1598    
1599    checkpoint48i_post
1600    o Changes to restore differentiability of code w.r.t. previous tag
1601      (mostly adding new routines to make list and replacing
1602      pressure by totPhiHyd).
1603    o Updated and merged grdchk package
1604      - has both ADM and TLM checks
1605      - works for single- and multi-proc.
1606      - output cleaned
1607      - worked successfully for parallel DIVA
1608    o genmake:
1609      - Adding -platform=SP4
1610      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1611    o Modif. for DIVA:
1612      ctrl_unpack should not be called in intermediate DIVA interval.
1613      (similar thing would apply for active files such as
1614      tbar, sbar, psbar, which should not be reinitialised;
1615      only relevant for ecco-branch)
1616    
1617    checkpoint48h_post
1618    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1619    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1620    o Added SEAICE_initialHEFF to pkg/seaice
1621    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1622    
1623    checkpoint48g_post
1624    --- EOS:
1625    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1626      store total Potential in totPhyHyd for diagnostics & EOS.
1627    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1628    --- Pressure/geopotential gradient:
1629    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1630    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1631      ( changes results of global_ocean_pressure )
1632    o NLFS + z-coord.: add eta*Rho' contribution.
1633    o accurate phiHyd when using interface-W at the middle between 2 centers
1634     ( changes results of ideal_2D_oce )
1635    o includes r* 2nd term in potential gradient.
1636    
1637    checkpoint48f_post
1638    Merging from release1_p12:
1639    o Modifications for using pkg/exf with pkg/seaice
1640      - improved description of the various forcing configurations
1641      - added basic radiation bulk formulae to pkg/exf
1642      - units/sign fix for evap computation in exf_getffields.F
1643      - updated verification/global_with_exf/results/output.txt
1644    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1645      (SBO) core products, including oceanic mass, center-of-mass,
1646      angular, and bottom pressure (see pkg/sbo/README.sbo).
1647    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1648      to avoid negative values in shallow regions.
1649      - updated verification/natl_box/results/output.txt
1650      - updated verification/lab_sea/results/output.txt
1651    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1652    o Added useSingleCpuIO option (see PARAMS.h).
1653    o Updated useSingleCpuIO option in mdsio_writefield.F to
1654      work with multi-field files, e.g., for single-file pickup.
1655    o pkg/seaice:
1656      - bug fix in growth.F: QNET for no shortwave case
1657      - added HeffFile for specifying initial sea-ice thickness
1658      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1659    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1660      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1661    o pkg/seaice:
1662      - adjoint-friendly modifications
1663      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1664    
1665    checkpoint48e_post
1666    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1667    o dynamics: change definition of computational domain & adapt mom_fluxform
1668      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1669    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1670        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1671        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1672        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1673        inverted_barometer solid-body.cs-32x32x1
1674      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1675    
1676    checkpoint48d_post
1677    o in preparation for r*:
1678     a) use pre-computed gradient of hydrostatic potential:
1679        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1680     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1681        => affects results of glob_oce_pressure (different truncation error)  
1682      update output.txt of ideal_2D_oce & global_ocean_pressure
1683    
1684    checkpoint48d_pre
1685    o in preparation for r*:
1686      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1687      pass the 2 comp. of the grad. as arguments to momentum S/R.
1688      but for the moment, only used if it does not change the results.
1689    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1690    
1691    checkpoint48c_post
1692    Modifications in treatment of initial flux forcing controls
1693    to avoid extra storing of flux fields.
1694    
1695    checkpoint48c_pre
1696    o Added tidal_basin_2d experiment (currently 1D!)
1697    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1698    
1699    checkpoint48b_post
1700    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1701     (modification to pressure gradient not yet implemented)
1702    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1703      (for U & V) that are used for vertical advection of momentum.
1704    
1705    checkpoint48a_post
1706    o In preparation for r*, use temp. array to compute vertical transport
1707       in flux-form momentum pkg. => change results of few test-exp.
1708      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1709                        lab_sea, natl_box & plume_on_slope
1710    
1711    checkpoint48
1712    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1713    
1714    checkpoint47j_post
1715    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1716    o moved adexch from forward_step to addummy_in_stepping
1717    o added exch in ctrl_map_...
1718    o aveFreq.=0. at end of cost_final to avoid overwrite in
1719      reverse checkpointing loop
1720    o Yet more changes in gmredi:
1721      * adgmredi_calc_tensor
1722        avoiding all recomputation of gmredi_slope_limit
1723      * adgmredi_x/y/rtransport
1724        added flag for excessive storing to avoid recomp. of
1725        u/v/rtans, dTdx/y/z
1726        -> this is not really necessary and very memory-consuming
1727      * adgmredi_slope_psi:
1728        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1729      * gmredi_slope_limit
1730        re-activated full calculation of taperfct for case 'ac02'
1731    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1732    
1733    checkpoint47i_post
1734    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1735    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1736      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1737    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1738    o gmredi: fix few bugs.
1739    
1740    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1741    This will be a good checkpoint to plug into the ecco-branch.
1742    o few modif.'s to get latest version adjointed
1743      (mainly kick out code in ini_linear_phisurf)
1744    o modif's to run adjoint with exactConserv
1745    o case GM_BOLUS_ADVEC should be cleaned
1746      S/R gmredi_slope_psi should be cleaned
1747    o verification/carbon now has exactConserv=.TRUE.
1748    
1749    checkpoint47g_post
1750    o time-average AIM output: becomes independent from statvars time-average
1751      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1752    o After TAF bug fix:
1753      Tested adjoint of gmredi package.
1754      Tests were done with checkpoint47 rather than with latest
1755      checkpoint47f_post since the latter is broken for the adjoint
1756      verification/carbon/ contains both ADM and TLM gradient checks.
1757    Here they are, before they get changed/lost/stolen.
1758    Mostly modif.'s to fix numerical sensitivities.
1759    Gradient checks OK for
1760    - GM_taper_scheme:
1761      * clipping
1762      * ac02
1763      * linear
1764      * glw91
1765      * dm95
1766      * ldd97
1767    - GMREDI_OPTIONS:
1768      * GM_VISBECK_VARIABLE_K
1769      * GM_NON_UNITY_DIAGONAL
1770      * GM_EXTRA_DIAGONAL
1771      * GM_BOLUS_ADVEC
1772    in conjunction with data.gmredi parameters to be checked in
1773    in a few minutes under verification/carbon/code/
1774    
1775    checkpoint47f_post
1776    Merging from release1_p10:
1777    o modifications for using pkg/exf with pkg/seaice
1778      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1779        and SEAICE_EXTERNAL_FLUXES
1780      - pkg/exf CPP options EXF_READ_EVAP and
1781        EXF_NO_BULK_COMPUTATIONS
1782      - usage examples are Experiments 8 and 9 in
1783        verification/lab_sea/README
1784      - verification/lab_sea default experiment now uses
1785        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1786    
1787    checkpoint47e_post
1788    o created a tag prior to creating a branch
1789    
1790    checkpoint47d_post
1791    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1792      at the bottom boundary had an erroneous half slip boundary condition
1793    o added bottom drag and no slip boundary condition capabilities to
1794      oceanic pressure coordinates code
1795    o added new verification experiment global_ocean_pressure, this experiment is
1796      also described in the tutorial section of the manual
1797    checkpoint47d_pre
1798    
1799    checkpoint47c_post
1800    o Added a verification experiment for a global cubed-sphere ocean run
1801      -  verification/global_ocean.cubed32x32x30
1802      -  uses pkg/therm_seaice and pkg/bulk_forcing
1803    
1804    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1805    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1806      when using P-coordinate; only implemented for atmospheric config.
1807    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1808      NOTES: requires option NONLIN_FRSURF to be "#define".
1809    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1810    
1811    checkpoint47b_post
1812    Merging from release1_p9:
1813    o pkg/seaice
1814      - removed GOTO's and added taf directives
1815      - double precision constants to reduce the g77 (Linux)
1816        to F77 (SGI) differences reported in release1_p8
1817    o tools/genmake
1818      - added SGI options
1819    o verification/testscript
1820      - updated to that of checkpoint47a_post
1821    o verification/global_ocean.90x40x15/input/eedata
1822      - modified for SGI f77 compatibility
1823    o verification/lab_sea
1824      - added description of sea-ice model
1825      - added missing matlab routines
1826      - added test of thermodynamics parallelization
1827    
1828    checkpoint47a_post
1829    o new pkg: aim_v23
1830     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1831       for now, keep the same surface forcing as before.
1832     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1833     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1834     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1835    o add diagnostic of surface correction term in monitor output
1836    
1837    o bulk_force and therm_seaice
1838    - Two packages:  bulk_force (Bulk forcing)
1839      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1840    - Earlier integration from Stephaine Dutkiewicz
1841      and Patrick Heimbach.
1842    - Two ifdef statements for compile time,
1843       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1844    
1845    checkpoint47
1846    differentiable version of checkpoint46n_post
1847    o bug fix in quasihydrostaticterms
1848    o * "clean" adjoint code (in terms of extensive recomputations)
1849        can now be obtained for all GMREDI options (i.e. for
1850        - GM_VISBECK_VARIABLE_K
1851        - GM_NON_UNITY_DIAGONAL
1852        - GM_EXTRA_DIAGONAL
1853        - GM_BOLUS_ADVEC )
1854      * However, wrong gradient check problem remains unsolved.
1855      * New CPP options have been introduced for different
1856        tapering schemes
1857    o external_fields_load now part of differentiation list
1858    o pressure needs multiple storing;
1859      would be nice to have store_pressure at beginning or
1860      end of forward_step, e.g. by having phiHyd global (5-dim.)
1861      (NB: pressure is needed for certain cases in find_rho,
1862      which is also invoked through convective_adjustment).
1863    o recomputations in find_rho for cases
1864     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1865    o #define ATMOSPHERIC_LOADING should be differentiable
1866    o ini_forcing shifted to begining of initialise_varia
1867    o Incorporating QNVS line search routines into MITgcm
1868      (this is separate code, and therefore not under pkg)
1869      lsopt/, optim/
1870    o Updated verification/carbon/
1871      - #define GM_VISBECK_VARIABLE_K
1872      - GM_taper_scheme    = 'ldd97'    
1873    
1874    checkpoint46n_post
1875    Merging from release1_p8:
1876    o verification/natl_box:
1877      updating new external_fields_load routine
1878    o New package: pkg/seaice
1879      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1880      The sea-ice code is based on Hibler (1979-1980).
1881      Two sea-ice dynamic solvers, ADI and LSR, are included.
1882      In addition to computing prognostic sea-ice variables and diagnosing
1883      the forcing/external data fields that drive the ocean model,
1884      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1885      The implied surface heat flux is then stored in variable
1886      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1887      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1888      non-local transport term.  Because this call precedes model
1889      thermodynamics, temperature under sea-ice may not be "exactly" at
1890      the freezing point by the time theta is dumped or time-averaged.
1891      N.B.: fairly large differences in accuracy occur across
1892            different platforms/compilers; comparison between
1893            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1894            generated output gives:
1895       T           S           U           V

1901      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1902    o GAD:
1903      - generated new common blocks to account for call of
1904        same gad routines with differing traceridentities
1905        (needed to modify tracerIdentity indices in GAD.h)
1906      - generated separate common blocks for case useCubedSphereExchange
1907        (Department of Futurology)
1908      - parameter lists to gmredi_?transport: added tracerIdentity
1909      - added new key indices to tamc.h
1910    o external_fields_load:
1911      - added this routine to TAF list
1912      - needed to make some common blocks global and additional storing
1913        along the same lines as exf package (checkpoint_lev?_directives.h)
1914    o exf:
1915      updated external forcing package
1916      - bug fixes carried over from ecco-branch
1917        (missing OBCS_OPTIONS.h in two routines)
1918      - enable easy to use "no forcing".
1919      - added exf I/O for atmospheric loading
1920      - added exf I/O for runoff data
1921      - transfered scaling between exf <-> MITgcm to exf namelist
1922    o Adding new verification experiment global_with_exf.
1923      This verification experiment is almost identical to the
1924      global_ocean.90x40x15 experiment, except that it uses
1925      the exf (and cal) package instead of the
1926      external_fields_load routine (cf README file).
1927    
1928    checkpoint46m_post
1929    o modified testscript to return -- when there are no lines of "%MON" output
1930    o added new flag "quasiHydrostatic" for QH mode
1931      and new routine quasihydrostaticterms()
1932    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1933      New routine: mom_u_coriolis_nh()
1934    o fixed sign of non-hydrostatic metric terms in u and v equations.
1935      Depend on correct sign of gravitySign.
1936    o added work.pc* to .cvsignore in aim directories using ifc
1937    o introduced flag for controllin non-hydrostatic metric terms
1938    o removed gravitySign from PARM04
1939    o switched to g77/ifc from pgf77 in aim experiments
1940    
1941    checkpoint46l_post
1942    o made convective adjustment work with pressure coordinates:
1943     - changed the direction of k-loop in convective_adjustment.F for the
1944       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1945     - adjusted the reference pressure k-index in convective_adjustment.F
1946     - adjusted the convection condition in convect.F (in analogy to
1947       calc_ivdc.F)
1948     - convective_adjustment no longer computes anything on the halos
1949     - removed the warnings about negative salinity from find_rho.F and
1950       find_alpha.F; instead the new routine look_for_neg_salinity, called
1951       at the beginning of find_rho, find_alpha, and find_beta, does a
1952       check of the entire slice, if CPP-option
1953       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1954    checkpoint46l_pre
1955    
1956    checkpoint46k_post
1957    o fixed the verification/global_ocean.90x40x15 experiment:
1958     - new bathymetry (the world according to A., JMC, and M.)
1959     - new initial fields and forcing fields (*.bin files)
1960     - new POLY3.COEFFS (for the next release one should switch to a full
1961       equation of state: JMD95P or MDJWF)
1962     - fixed several errors and redundancies in the data file
1963     - experiment uses looped cells
1964     - added matlab directory with diagnostic scripts for plotting of output
1965    
1966    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1967     - read AIM physics parameters from a file (data.aimphys)
1968     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1969    
1970    checkpoint46j_post
1971    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1972    o move wVel computation at the end of the time step, in S/R integr_continuity
1973    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1974    o update timeave pkg for wVel diagnostic.
1975    checkpoint46j_pre
1976    
1977    checkpoint46i_post
1978    o Clean up AIM package (and keep the results unchanged):
1979      include CPP_OPTION and use IMPLICT NONE in all routines ;
1980      declare all the variables _RL ; use _d 0 for all numerical constants.
1981      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1982    
1983    checkpoint46h_post
1984    o cleaned up the use of rhoNil and rhoConst.
1985      - rhoNil should only appear in the LINEAR equation of state, everywhere
1986        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1987        and the dynamical equations are all divided by rhoConst
1988    o introduced new parameter rhoConstFresh, a reference density of fresh
1989      water, to remove the fresh water flux's dependence on rhoNil. The default
1990      value is 999.8 kg/m^3
1991    o cleanup up external_forcing.F and external_forcing_surf.F
1992      - can now be used by both OCEANIC and OCEANICP
1993    checkpoint46h_pre
1994    
1995     Added code to convert surface volume flux (fresh water) into
1996     a mass flux when using P coordinates in the ocean (OCEANICP).
1997     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1998    
1999    checkpoint46g_post
2000    o Include a new diagnostic variable phiHydLow for the ocean model
2001      - in z-coordinates, it is the bottom pressure anomaly
2002      - in p-coordinates, it is the sea surface elevation
2003      - in both cases, these variable have global drift, reflecting the mass
2004        drift in z-coordinates and the volume drift in p-coordinates
2005      - included time averaging for phiHydLow, be aware of the drift!
2006    o depth-dependent computation of Bo_surf for pressure coordinates
2007      in the ocean (buoyancyRelation='OCEANICP')
2008      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2009        Theta, Salinity, and Pressure in the parameter list. This routine is
2010        presently contained in find_rho.F. This routine does not give the
2011        correct density for 'POLY3', which would be a z-dependent reference
2012        density.
2013    o cleaned up find_rho
2014      - removed obsolete 'eqn' from the parameter list.
2015    o added two new verification experiments: gop and goz
2016      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2017    checkpoint46g_pre
2018    
2019    checkpoint46f_post
2020    o Enable tangent linear (forward mode) gradient checks:
2021      - extended active file handling to g_... files
2022      - added TANGENT_SIMULATION to theSimulationMode
2023      - extended grdchk package accordingly
2024    o added tangent linear setup in verification/carbon/code_ftl
2025    o added adjoint setup in verification/front_relax/code_ad
2026    
2027    checkpoint46e_post
2028    o Added new equation of state -> MDJWF
2029      - EOS of McDougall et al., 2002, JAOT, submitted
2030      - caveat: the equation of state is only valid for a smaller (more
2031        realistic?) range of values than JMD95P/Z and UNESCO
2032      - added masks to the calculation of pressure in store_pressure
2033      - added more check values for density in check_eos (ini_eos.F), some of
2034        the old check values are out of the range of the MDJWF-eos, so don't
2035        expect perfect matches for those
2036    checkpoint46e_pre
2037    
2038  checkpoint46d_post  checkpoint46d_post
2039  o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and  o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2040    'OCEANICP', also initialised field pressure correctly in ini_eos in the    'OCEANICP', also initialised field pressure correctly in ini_eos in the
