5      ==============================      ==============================
6    
7    o fix bug (typo) in obcs_apply_eta.F
8    o add a new package shelfice which enables us to model the circulation
9      underneath shelf-ice with draughts of hundreds of meters.
10     - works
11     - to do: + include improved thermodynamics
12              + check whether kSurfC (from model/inc/SURFACE.h) can be used
13                instead of new field kTopC
14              + can we use topoFile, Ro_surf and existing code in ini_depth.F
15                instead of new field R_shelfIce and new code in ini_depth.F
16                and ini_mask_etc.F?
17    o seaice pkg:
18     - add a cpp-flag to include a simple formula for a salinity dependent
19       freezing point of sea water at the surface
20     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
21       meridional stresses are now different (and hopefully correct)
22    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
23       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
24       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
25    o pkg/diagnostics: add options and parameters for regional-statistics
26       diagnostics ; define regions by reading a region-mask from a file
27       (might add other options later)
28    o pkg/bulk_force:
29     - add option and parameters to use AIM surface-flux formulae.
30     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
31       others forcing fields (defined in PARM05, parameter file "data") are loaded
32       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
33     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
34     - use the right EXCH call for uwind,vwind (to work on CS-grid).
35     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
36       and parameters (note: calcWindStress replaces .NOT.readwindstress).
37     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
38    
39    checkpoint58
40    o add "--embed-source" option to genmake2 which, when the supporting
41      tools can be compiled (as determined by genmake2) will turn on the
42      embed_files package which then embeds the entire MITgcm source code
43      (*.[fFhc] + Makefile) used for the build within the executable
44      - requested by CNH but off by default
45      - adds a paltry <9MB to the mitgcmuv executable in most cases
46      - only writes the output when useEMBEDSRC in eedata is true
47    o clean up 3-dim. relaxation codes:
48      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
49      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
50      * Thanks to Tom Haine for testing!
51    
52    checkpoint57z_post
53    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
54      affects output (@ truncation level) of exp. plume_on_slope ; updated.
55    o fix the pickup behavior for obcs in combination with ptracers
56    o fix a bug in ptracers_external_fields_load
57    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
58      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
59    o transfered surface NH pressure to eta field (if exactConserv).
60    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
61         and update lab_sea output.txt file.
62    o completing 3-dim. relaxation code: additional term
63         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
64      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
65      * At compile time, in "EXF_OPTIONS.h" set
66          #define  ALLOW_CLIMTEMP_RELAXATION
67          #define  ALLOW_CLIMSALT_RELAXATION
68      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
69          tauThetaClimRelax3Dim = 15552000.0,
70          tauSaltClimRelax3Dim  = 15552000.0,
71      * 3 cases:
72          1) Use a constant-in-time 3-dim. field
73          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
74          3) Real-time relax. to time-evolving prescribed field
75    o Adding Laplacian-type smoothness constraint on
76      initial and boundary (forcing) controls (ic, bc)
77      * enable at compile-time via
78        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
79      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
80      * Absolute scale somewhat unclear so far
81      * no area weighting was included since no other cost term does so far
82    
83    checkpoint57y_post
84    First step for a NLFS adjoint
85    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
86    o new init. routines for calc_r_star, calc_surf_dr
87    o still need to deal with ini_masks_etc
88    o testreport seemed happy
89    checkpoint57y_pre
90    
91    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
92    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
93    o add new offset feature to offline pkg (plus minor cleanup)
94    o cfc fixes for final year of integration
95    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
96      be in GCHEM_OPTIONS).
97    
98    checkpoint57x_post
99    o fix testreport Pb in multiple test experiment.
100    o cleanup our namelist syntax in verification:
101      - make it more F95 standards compliant (some work still needed)
102      - allows the vast majority of our tests to work with gfortran
103    o Non-Hydrostatic:
104     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
105     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
106    o Allow to apply AB on T,S rather than on AB(gT,gS):
107     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
108     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
109       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
110     - need a "clever" read_pickup to restart from the other AB formulation
111    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
112    o remove some unused variables (reduces number of compiler warnings)
113    o adjoint
114      * Disable useVariableViscosity for adjoint for time being
115        (there are a number of extensive recomputations)
116      * Initialize certain variables needed for adjoint
117    
118    checkpoint57w_post
119    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
120                 fix the singleCpuIO RS version of MDSWRITEFIELD
121       and add a WARNING if using globalFiles=T with multi-processors.
122    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
123      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
124    o tracer advection scheme:
125      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
126       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
127       was not very convenient).
128      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
129       (further tests needed for the implicit DST & Flux-Limiter schemes).
130    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
131      and sRef for convenience, handy, when you want to initialize
132      ptracers in a large domain with a constant non-zero value. Also,
133      untangle ptracers_init.F a little.
134    
135    checkpoint57v_post
136    o change dome exp. to use variable viscosity in side-drag terms.
137    o remove all the files from the cfc_offline test since they are now
138      incorporated into tutorial_cfc_offline which has been producing
139      identical results for a few days of testing
140    o add new parameter: sideDragFactor to enable half-slip-side BC
141      and change side-drag S/R to use viscosity from mom_calc_visc
142      (can switch back by setting sideDragFactor=0.); affects results at
143      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
144       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
145    o vorticity & strain are now computed without masking, to account for
146      no-slip-side BC in variable viscosity calculation ; mask is applied
147      anyway later on, before computing advection/coriolis terms.
148    o modify exp4 to test new obcs support for reading from external files
149      and for passive tracers
150    o fix behavior of ptracers_monitor when monitor output is written to a
151      netcdf-file; still not independent of monitor.F (writes in the same
152      file).
153    o change default value of tRef (put a uniform, meaningful value for ocean
154      & atmos) and initialize sRef (was missing, as Martin mentioned).
155    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
156      to be proportional to enstrophy dissipation length.  Thus,
157       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
158      This is now consistent with Smagorinsky and with the manual.
159    
160    checkpoint57u_post
161    o OBCS and PTRACERS: add open boundary support for passive tracers
162      - either use homogenous (pseudo) v.Neumann conditions or prescribe
163        OB-values from file; this is not different from the way theta and salinity
164        are treated
165      - however, Orlanski-radiation conditions are not supported, and the model
166        will stop if you use pTracers and Orlanski at the same time.
167      - beefed up the rountine obcs_external_fields_load: now only those open
168        boundary values are overwritten with values from files for which there
169        are really files, otherwise the OB-fields remain untouched. This makes
170        it possible to use different OBs at different ends of the domain (as
171        with EXF)
172    o reduce number of exch calls in shap_filt (s2).
173    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
174      truncation level) 4/5 MLAdjust test results (11&12 digits match).
175    
176    checkpoint57t_post
177    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
178    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
179      same truncation, independent of the face number: affects affects several
180      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
181    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
182      note that biharmonic viscosity + no-slip was not tested in any experiment.
183    o fix bug in non-linear free-surf side-drag ; generate new output for
184      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
185    o make mnc honor the writeBinaryPrec flag for most kinds of output
186    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
187    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
188      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
189    o add brackets in multi-terms sum to get same truncation, independent of
190      the face number (manage to get exactly same value of gU,gV at the cs-edge)
191      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
192    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
193      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
194      a maximum grid-scale Reynolds number.  Also, changes all length calculations
195      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
196      Suggested values of viscosity parameters found in mom_calc_visc.
197      Many new viscosity diagnostics available.
198    
199    checkpoint57s_post
200    o Add clearing-house for viscosity calculations, mom_calc_visc and
201      correct numerous bugs in LeithD and Smagorinsky discretizations.  
202      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
203      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
204      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
205      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
206      The Strain-Tension form is now called with useStrainTensonVisc=.true.
207      ViscAhStrain and viscAhTension are now retired.
208    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
209    o In response to JMC's bug report, genmake2 now ignores any soft-links
210      that it finds in the *current* directory when searching for files.
211      Soft-links found in any other source directories will still work as
212      they did before.
213    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
214      a C routine to unlimit the stack size
215    o mnc-ify pkg/aim snapshot vars
216    o mnc-ify pkg/land as requested by Daniel
217    o various changes to mnc including:
218      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
219      - output can now be grouped so that all files within a group
220          change the ITER portion of their names in lock-step together
221      - can now read ("global") PER-FACE (in addition to PER-TILE) files
222          and works with both EXCH1 and EXCH2 (but needs more testing)
223      - writing works for all verification test cases w/ g77 on Linux
224    
225    checkpoint57r_post
226    o make MNC variable initialization happen earlier
227    o add diagnostics for (almost) each term of the momentum Eq.
228    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
229    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
230    o remove MINIMAL_TAVE_OUTPUT option ;
231      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
232    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
233      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
234    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
235    o add time-dependent SST, SSS control
236    o cost terms in ecco/ modularized (new cost_generic.F)
237    o cost_averages routines are modularized (new cost_averagesgeneric.F)
238    o new infrastructure for seaice model vs. obs misfits in seaice/
239      * driver from the_main_loop.F is seaice_cost_driver.F
240      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
241      * gradient check in Exp. 6a of natl_box_adjoint/
242    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
243      (see README file)
244    
245    checkpoint57q_post
246    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
247    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
248      - bug was reported by Jean-Michel and Ian Fenty
249    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
250      update exp. cpl_aim+ocn output.
251    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
252      Needed for high-res. runs with large global files
253      to be able to limit tapelev size
254    o Changed some tests for adjoint:
255      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
256      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
257      * global_ocean.90x40x15/ back to default 3-level checkpointing
258    o Modifications to enable scripted COMMON to MODULE conversion
259      * verification/OpenAD/code/ has necessary scripts and description;
260      * converts, compiles and runs successfully;
261    
262    checkpoint57p_post
263    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
264    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
265      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
266    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
267    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
268      (was already the case for dissipation with mom_vecinv,
269       and also the case for grad.PhiHyd when staggered-timeStep)
270      This will allow to put dissipation out-off the AB time-stepping.
271     Unfortunately, affects truncation error. Update output of exp. that "fails"
272      (cg2d matching number) and leave the others for later: front_relax(10),
273      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
274      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
275    
276    checkpoint57o_post
277    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
278      (2) its ready to be documented during the 20050801 DocFest
279    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
280      for ideal_2D_oce and lab_sea on linux_ia32_g77
281    o set to #undef CTRL_SET_OLD_MAXCVARS_30
282      in global1x1_tot/code_seaice_adj to access indices 32, 33
283      (worth another tag)
284    
285    checkpoint57n_post
286    o adding precip control xx_precip 32
287    o adding swflux control xx_swflux 33
288    o Replacing 10 forcing penalty cost routines by 1 generic.
289    o Implementing partitioning in time-mean and variable adjustment
290      for atmos. state.
291    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
292    o in natl_box_adjoint:
293      * updated exp 1 to 10
294        (but does not have time-mean vs. variable split results yet)
295    o updated global1x1/*_seaice_adj/
296      to incorporate latest changes
297    o enable useSingleCpuIO for mdsio vector routines
298      (applies in particular to tapelev I/O)
299    o removed inefficient K-loop in all active_file*control*.F
300    
301    checkpoint57m_post
302    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
303      and advect_cs (use EXCH-2 and standard cs-32 grid files).
304    o pkg/exch2: filling of face-corner halo regions is optional
305      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
306    
307    checkpoint57l_post
308     tag before updating tutorials (pre-release-2)
309    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
310       for output and interpolation of input fields onto model grid)
311    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
312       Affects results of exp. rotating_tank ; update output.txt.
313    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
314          and taking the square quantity and/or using a fraction-weight field.
315    o fix aim_diagnostics_init.F mate numbers.
316    o add mnc output capability to diagnostics/diagstat and update
317      our cvsignore files for the ACSII output generated
318    
319    checkpoint57k_post
320    o lab_sea now uses diagnostics package and provides a suite of
321      new EXF diagnostics output.
322    
323    checkpoint57j_post
324    o exf
325      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
326        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
327        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
328      * extended diagnostics output
329        - now includes all EXF variables
330        - hs, hl moved to common block
331        - separate S/R for diagnostics, called after ctrl vector is added
332        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
333        - EXFqnet contains true Qnet (i.e. includes qsw)
334      * updated verif. lab_sea, global_with_exf
335      * Rearranging hflux (exf_mapfields -> exf_getforcing)
336        to ensure that diagnostics sees a true EXFqnet
337    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
338    o diagnostics pkg: change pointers so that 1 diagnostic can be used
339      several times with different frequencies.
340    o mnc-ify the thsice package as requested by Daniel Enderton
341      - the monitor--MNC output needs work
342      - many attributes need to be added (most are currently blank)
343    o mnc-ify theaim_v23 package as requested by Daniel Enderton
344      - many attributes need to be added (most are currently blank)
345    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
346    o add Sadourny like discretization to the 4th.O vorticity advection scheme
347    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
348      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
349         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
350    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
351     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
352    
353    checkpoint57i_post
354    o Diagnostics package was changed: diagnostic allocation is now deactivated
355      by setting an empty file name in the namelist (used to be by setting 0 frequency)
356    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
357      add 1rst Order upwind vertical Shear.
358    o add a quick fix for A/B checkpointing in OFFLINE mode
359    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
360      end-run around the C/Fortran linking horror in eesup/src/timers.F
361    o added pkg/runclock: allows user to terminate run based on wall clock
362    o added non-hydrostatic scaling parameter: nh_am2
363    o pkg/my82: futile attempt to make results compiler-independent by adding
364      some "_d 0", etc. no effect.
365    o for mnc output, fill the 'T' coordinate var with myTime and create a
366      separate 'iter' variable for iteration count
367    o pkg/diagnostics:
368      add new capability: output of Global/Regional & per-level statistics ;
369      tested against monitor output (including land & thSIce) on various exp.
370    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
371    
372    checkpoint57h_done
373      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
374      data.diagnostics, data.gchem, data.ptracers) is done.
375    
376    o pkg/diagnostics: prepare for Global/Regional statistics.
377      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
378    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
379      and rename it: DIFFERENT_MULTIPLE
380    
381    checkpoint57h_post
382    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
383    o pkg/diagnostics: change output frequency, now in seconds (instead
384      of Nb of iterations). This requires to change data.diagnostics.
385    checkpoint57h_pre
386    
387    o in mnc, let the user create the output dir if both mnc_outdir_date
388      and mnc_outdir_num are false
389    o add fflags() to pkg/diagnostics which allows one to specify, on a
390      per-file basis, the file precision [default behavior is unchanged]
391    o added diagnostics to pkg/kpp, including computation of mixed layer
392      depth based on a temperature/density criterion
393    o updated verification/natl_box to test the new pkg/kpp diagnostics
394    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
395    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
396    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
397      not mnc -- this mistake was found by JMC and is now corrected
398    
399    checkpoint57g_post
400    o add Adams-Bashforth 3rd Order time stepping:
401      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
402      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
403    checkpoint57g_pre
404    
405    o make lambda[Theta,Salt]ClimRelax spatially varying
406      (default remains spatially uniform constant based on tau)
407    o added new control variables
408      * init. uVel, vVel, etanN
409      * lambda[Theta,Salt]ClimRelax
410    o separate masks used for ctrl_pack/unpack 'from write_grid' output
411      (suggested by G. Forget)
412    
413    checkpoint57f_post
414    o add parameter "baseTime" = model base time = time at iteration zero
415      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
416      account for baseTime shift
417    o move Coriolis arrays from PARAMS.h to GRID.h
418    checkpoint57f_pre
419    
420    o mnc-ifying the seaice package
421    o introduced an alternative length scale calculation for use in the limiting
422      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
423    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
424    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
425      as well as grad(vort3).  Made it compatible with both approximate form
426      for the cubed sphere and full form of these gradients.  Added flag
427      useFullLeith to select between approximate and full form.  
428    o add "d0" in getcon.F to reduce differences between compilers/platforms
429      update output.txt of exp. fizhi-gridalt-hs
430    o change port_rand funtion to allow to set the seed.
431    o fix obscure MNC bug involving conversion between reals and integers
432      - it caused no problems with certain (eg. gcc, ifc) compilers but the
433        new version is now more standards-compliant
434    o adjoint-related modifications
435      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
436      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
437      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
438    
439    checkpoint57e_post
440    o Adding eddy stress controls a la Ferreira et al.
441    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
442    
443    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
444      update output.txt of exp. fizhi-gridalt-hs
445    o add more "Z" dimensions and associated coordinate vars to MNC
446    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
447    o parameter calendarDumps: when set, approximate months (30-31 days) and years
448      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
449      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
450      months and years.  Requires pkg/cal.
451    o diagnostics: add pickup functionality
452      - off by default for backwards compatibility
453      - current version only uses MDSIO -- MNC will be added
454    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
455    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
456    
457    checkpoint57d_post
458    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
459    o modify verification/ideal_2D_oce so that it tests the creation of mnc
460      output from the diagnostics package
461    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
462    o make genmake2 more portable by using ".$FS" instead of ".f" for more
463      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
464    o add coordinate variables to the MNC output from the diagnostics package
465    o change MNC-flags default value: true when useMNC=TRUE
466    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
467      the ability (off by default) to read the grid information using MNC
468    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
469    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
470    o do snap-shot diagnostics at the middle of the time-interval (instead of
471      at the end).
472    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
473      new test for AIM with thSIce + slab-ocean
474    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
475    o move state variable diagnostics to the beginning of the time step ;
476      (note: still needs some work specially for snap-shot diagnostics)
477      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
478    
479    checkpoint57c_post
480    o Change testing option (-ieee) to get closer agreement between g77 & ifort
481    o generate new output.txt files on faulks with g77 & the new -ieee option
482    checkpoint57c_pre
483    
484    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
485      update output.txt of exp. global_ocean.90x40x15
486    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
487      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
488    o add saltFlux(+File) forcing capability with periodicExternalForcing
489    o allow to use pkg diagnostics for GM-Redi & ThSIce output
490    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
491    o improvements for the MNC output from DIAGNOSTICS:
492      - correct handling of the unlimitied dimension
493      - all dims now have associated coordinate variables
494      - variables located at U, V, and Corner ("Z") points are now written
495        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
496        *all* data points are output
497    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
498    o added pkg/seaice/seaice_monitor.F
499    o mdsio_readfield.F can now read files visible only to master MPI process.
500    o pkg/seaice: some test code for ice-modified ocean stress
501    o exf_getffields interpolation defaults to bilinear for all scalar forcing
502      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
503      spurious negative numbers for precipitation and humidity.  Will cause
504      some small numerical differences for integrations using pkg/exf/exf_interp.F.
505    o pkg/ctrl/
506      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
507        May be enabled via doPackDiag
508      *  introduce z-scaling of
509         + gradient (doZscalePack) and
510         + control (doZscaleUnpack)
511    o pkg/mdsio/
512      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
513      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
514    
515    checkpoint57b_post
516    o simplify options in diagnostics_fill arguments (remove weird combinations)
517    o fix MNC coordinate variables so that they now contain per-face index
518      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
519      general, EXCH2 grids are only aligned to a "local" coordinate system
520    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
521    o Implement instantaneous output within pkg diagnostics:
522      setting a negative frequency in data.diagnostics produces
523     "snap-shot" output (as opposed to time-average if freq > 0)
524    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
525      NOTE: change ptracer diagnostics name: use 2 characters to work with
526            more than 9 tracers. Add also diagnostics of advect & diffus flux.
527    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
528      becomes the coordinate variable for the 'T' dimension
529    o add CF-style coordinate variables to MNC
530      - just a first cut:  numbers are meaningless on the cubesphere and
531        missing along the T axis but otherwise it works!
532    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
533    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
534    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
535      this is based directly on what the model compute, so that the content of
536      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
537    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
538    o clean up build options files for SunOS, in particular
539      - remove -traditional from xmakedepend
540      - change -xarch=v9 to -xarch=native for f77
541      - restore use of make (not gmake)
542      - add CC=gcc if using g77
543    o changes per discussion of AM, JMC, & EH3 today:
544      - move redundant "grid" variables out of "state" -- in preparation of
545        creating proper CF-style coordinate variables and in recognition
546        that any/all grid variables can be easily copied (eg. w/NCO) from
547        the grid files into any of the other NetCDF files
548      - *always* output grid variables with MDSIO (this will eventually be
549        changed)
550      - output MNC grid file if useMNC is true
551    o every instance of _END_MASTER() has been found and replaced with
552      _END_MASTER( myThid ) in order to satisfy certain picky Sun
553      preprocessors
554    o re-arrange diagnostics pkg initialisation:
555     - allow each package to extend the available diagnostics list
556     - add some checking and fix small problems (multi-threaded, ...)
557     - new S/R diagnostics_fill (replace fill_diagnostics):
558       look through the short list of active diag. (instead of the long list)
559       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
560    
561    checkpoint57a_post
562    o this set of changes restores TAMC compatibility
563      tested for global_ocean.90x40x15 adjoint on trough
564      (what a pain)
565    
566    checkpoint57a_pre
567    o some modifs in tools/build_options for sunos
568    o call ctrl_pack for ctrl at end for optimcycle=0
569    
570    checkpoint57
571    o add horizontal bi-harmonic viscosity for vertical velocity
572      - new parameter viscA4W (defaults to viscA4)
573      - affects only non-hydrostatic code
574      - to be done: no-slip lateral boundary conditions
575    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
576    o implement Implicit Vertical advection for pTracers
577    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
578      (implemented also for implicit vertical diffusion & advection)
579    o OBCS: extend application of tracer open boundary conditions
580      to a strip beyond the boundary of width Olx/Oly
581    o add call monitor to TAF set of required calls (flow directives)
582      and include in natl_box_adjoint
583    o untangle a few ifdefs related to cost, ctrl, autodiff
584      untangel a few ALLOW_ECCO_OPTIMIZATION
585    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
586      (theta2, salt2 in ecco_cost_weights)
587    
588    checkpoint56c_post
589    o OBCS as control variables
590      - update ctrl_ad_diff.list, obcs_ad_diff.list
591      - remove balance of obcs controls from default
592      - fix index bug nobcs in ctrl_init
593      - fix dummy fields filen in ctrl_pack
594      - add dummy weights for obcs
595    o lsopt: comment out fort.94 output
596    o optim:
597      - remove unnecessary header files
598      - adjusted namelists
599      - add xerbla.F to Makefile
600    o exf:
601      - multiple modifications of exf_check_range
602      - unit change in exf_init_runoff from [m/year] to [m/s]
603    o mdsio:
604      - i/o-vector change debugLevel from debLevA to debLevB
605    
606    checkpoint56b_post
607    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
608      is called from DO_THE_MODEL_IO
609      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
610      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
611      - clean up PTRACERS_WRITE_TIMEAVE a little
612    o add another verification experiment that tests both the cfc-pkg and
613      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
614      reactive tendencies treated inline with regular timestepping
615    o testreport previously did a lousy job of comparing small numbers, so
616      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
617      implemented in the little c-progam tmp_cmpnum.c which is embedded in
618      testreport.
619    o ptracers_monitor: bug fix for MPI
620    
621    checkpoint56a_post
622    o GCHEM: finish reorganizating the package
623      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
624        (introduces another 3D-array for each passive tracer, but only if
625        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
626        gchemTendency is not needed because the timestep is done separately)
627      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
628      - GCHEM is now---more or less cleanly---separate from PTRACERS
629      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
630        so clear to me how that should be done in a general way.
631    o CFC: improve formatting of output in CFC_ATMOS
632    o PTRACERS:
633      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
634        that ALL experiments with ptracers enable can be checked. This makes
635        GCHEM_MONITOR obsolete.
636      - include a runtime parameter PTRACERS_monitorFreq that defaults to
637        monitorFreq
638      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
639    o add PTRACERS (PTR0[1-5]) to testreport output
640    o exf_check_range:
641      * default changed to .TRUE.
642      * will check values for niter0 if debLevA, every timestep if debLevB
643      * STOP in exf_check_range if 'out of range'
644      * range chosen generous to allow for potential extema
645      TBD: a version with stricter range
646           permitted range would be runtime parameters
647    o GMredi:
648      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
649      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
650      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
651    o GCHEM:
652      - move call to GCHEM_FORCING_SEP, so that it is now called before
653        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
654      - introduced a useGCHEM runtime flag and applied it everywhere.
655      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
656        this flag is now only visible within GCHEM-pkg routines.
657      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
658        be replaced by a 3D array that is computed before thermodynamics; for
659        this, the tracer ID iTracer had to be included into the parameter list
660        of ptracers_forcing
661      - set up forward_step to call gchem_forcing, that will replace
662        gchem_forcing_int in ptracers_forcing
663      - cleaning up
664    o small cleaning of exch2: remove files that are also in eesupp/src
665    
666    checkpoint56
667    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
668    o mnc: cleanup "full" files--fixes out-of-memory problem
669    o ECCO-GODAE
670      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
671      * fully merged and updated from SIO code
672        windstress sign change affects
673        - exf_inscal_[u/v]stress
674        - sign of xx_tau[u/v] adjustments
675        - signs in cost_scat
676      * ctrl_get_gen: avoid update of tau[u/v] for first few days
677      * natl_box_adjoint updated and compressed
678      * 2-level checkpoint switch added
679        (tested in EXP. 1 of natl_box_adjoint)
680      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
681    o SVD
682      * first complete, non-hacked version for SVD calculations
683      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
684        performed via direct access files admtlm_vector.it????
685        (via ctrl_[un]pack)
686      * optimcycle is used for ARPACK iteration counter
687        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
688      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
689        and add linear transforms where necessary
690      * controls are initial/final SST, SSS (can be extended; need to check
691        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
692    o mdsio: filename info to both stderr, stdout
693    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
694      from sign change
695    
696    checkpoint55j_post
697    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
698      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
699    o add consistent build directories and .cvsignore files to verification
700    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
701    o make all subroutines 30 or less characters in length for certain older
702      compilers to work (a thorough search only turns up two routines in
703      pkg/ptracers)
704    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
705      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
706    
707    checkpoint55i_post
708    o change arrays for total vertical diffusivity (2.D if explicit,
709      3.D if implicit) ; each ptracer uses its own background value.
710    o added mnc/NetCDF output capability to ocn_compon_interf
711      - added bits to verification/cpl_aim+ocn so that it can run on
712        ITRDA and other clusters without the mpirun "-wd" option
713    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
714      configuration
715    o give MNC the ability to create additional files rather than
716      exceeding a specified file size limit "MNC_MAX_FILESIZE"
717      - the default is just less than 2GB which is a practical limit
718        on many systems
719    o Compute the non-local term using either KPP vertical diffusivity (=default)
720       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
721    
722    checkpoint55h_post
723    o add verification test "vermix"
724    o remove all the *_ioinc flags and replace with the single global
725      outputTypesInclusive flag
726    o allow to set a vertical profile of vertical diffusivity for T & S
727    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
728    o useMNC moved from data.mnc to data.pkg
729    
730    checkpoint55g_post
731    o Renaming carbon AD experiments to comply with testreport conventions
732    o Updating adjoint of Held-Suarez hs94.1x64x5
733    o Fixing directives for non-ECCO forward_step, after ECCO directives
734      have been fixed to avoid recomp. of do_oceanic_phys
735      Works well for global_ocean.90x40x15,
736      but recomp. issue remains for carbon
737    o Updating adjoint output for natl_box_adjoint after
738      pkg/ecco has been modified (see taga c55d_post)
739    
740    checkpoint55f_post
741    o rename to timeave_init_fixed
742    
743    checkpoint55e_post
744    o some delicate re-shuffle of store directives to avoid one
745      extra call of do_oceanic_physics
746      affects ecco_the_main_loop.F, do_oceanic_physics.F
747      checkpoint_lev1_directives.h
748    o NB: this may break global_ocean adjoint temporarily,
749      but it is clear how to fix it. Will do later, need this now.
750    
751    checkpoint55d_post
752    o ECCO specific cost function terms (up-to-date with 1x1 runs)
753    o ecco_cost_weights is modified to 1x1 runs
754    o modifs to allow observations to be read in as
755      single file or yearly files
756    o enable to read exf forcing fields as either
757      single file or yearly files (flag useExfYearlyFields)
758    checkpoint55d_pre
759    
760    o switch between 2-level and 3-level checkpointing
761    o add ability of MNC to write local and "partial" (eg. 2D slices where
762      the full 3D field is never actually stored) arrays to NetCDF files
763      with the correct (that is, the complete multi-dimensional) set of
764      array indicies
765      - used in mom_vecinv() to write the diagFreq output
766      - tested (demonstrated) in verification/aim.5l_cs
767    o further mnc-ification
768      - add verification/lab_sea to the list with mnc setups
769      - fix undefined mnc v-names in cd_code
770      - add kpp to mnc output (both snapshot and timeave)
771    o non-hydrostatic code
772      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
773        in calc_gw.F
774      - defaults to viscAh
775      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
776        friction or Leith) in non-hydrostatic mode, as long as there is
777        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
778    o pkg/cost
779      extend simple cost functions to treat time mean quantities
780      (T,U,V) via cost_accumulate_state from cost_tile
781    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
782        be 2 times larger than the minimum size the advection scheme requires.
783        now get a perfect conservation of salt in advect_cs test-exp (updated)
784    o GGL90 (Gaspar's TKE mixed layer)
785      - add horizontal diffusion of TKE, requires exchanges in
786        do_fields_blocking_exchanges, horizontal diffusivity is zero by
787        default. In OPA there is no horizontal diffusion of TKE but the
788        mixing coefficients are computed from a horizontal average of TKE of
789        6 points or so. I think that diffusion has a little more physical
790        justification.
791      - clean up ggl90_calc in the hope of reducing memory usage (this hope
792        was in vain)
793      - mask tke-variable in ggl90_init
794    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
795    o fix biharmonic diffusion on CS-grid.
796    o more obcs stuff
797      - added obcs_external_fields_load as an alternative to the EXF-pkg option
798        for reading boundary values. This routine is called from
799        obcs_prescribe_read
800      - updated obcs_check
801      - changed sponge layer relaxation parameter units for days to seconds
802      - turned off sponge layer by default
803      - changed argument list of OBCS_CALC to myTime+deltaTclock
804      - fixed about 35 bugs in obcs_external_fields_load
805    
806    checkpoint55c_post
807    o obcs stuff
808      - new runtime flags useOBCSprescribe, useOBCSbalance
809      - re-arranged obcs_calc
810      - moved exf_getobcs to obcs_prescibe_read
811        obcs_prescibe_read is called after ORLANSKI stuff
812        and independent of it (executable can contain all).
813      - updated obcs_check
814      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
815        These may be necessary only if tangential velocities are
816        prescribed at OB, not sure, needs testing.
817    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
818      which simplifies the calls and passes the ifc check-bounds test
819    
820    checkpoint55b_post
821    o add a 2D scalar, Z location, exchange_2 routine.
822    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
823      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
824      affects advect_cs results (for the wrong reason): update output.txt
825    o use a more standard discretization for biharmonic viscosity ;
826     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
827      affects results of dome set-up: update output.txt
828    o fix gad_advection.F (CubedSphere part), back to version 1.23
829    o fix bug in mom_vi_del2uv.F (CubedSphere part).
830    
831    checkpoint55a_post
832    o merged code to
833      * prescribe/read time-dependent open boundaries
834        (works in conjunction with exf, cal)
835      * sponge layer code for open boundaries
836      * each boundary N/S/E/W now has its own CPP option
837        (healthy for the adjoint)
838    
839    checkpoint55
840    o up-to-date adjoint of previous breaks
841      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
842      - global_ocean_ebm: adjoint still needs fix (TLM ok)
843      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
844      - carbon: * remove tr1-related adjoint verification
845                * add ptracer as control variable
846    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
847      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
848    
849    checkpoint54f_post
850    o in verification/carbin/ remove experiment related to
851      ALLOW_PASSIVE_TRACER (array tr1 etc)
852      code_ad/ input_ad/ results_ad
853    
854    o add two new packages
855      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
856        + subject to optimization (memory)
857      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
858        + subject to reordering (many GOTOs in the original code)
859        + so far opps is called for every (i,j) point, and then operates in
860          the vertical; one may want to reorder the scheme in order operate in
861          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
862          fields)
863    o overhaul of IO so that we now have flags for MDSIO and/or MNC
864      - all verification tests compile and run with linux_ia32_g77
865      - defaults are compatible with current input files--nothing
866        should change if you were not previously using MNC
867      - MNC output has been added in numerous places (eg. timeave)
868        but there are still a few writes not yet do-able with MNC
869        (this is in progress)
870      - flags now allow for either/or/both use of MDSIO and MNC and
871        documentation will soon follow
872      - numerous small formatting cleanups for ProTeX
873    o add version info (via BUILD_INFO.h) to MNC and stdout
874    
875    checkpoint54e_post
876    o add two new packages
877      - pp81 (Packanowski and Philander, 1981), Richardson number and
878        stratification dependent mixing
879      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
880      - these scheme operate in a similar manner as KPP (without ghat, of
881        course), however there is only one diffusivity that is used for both
882        temperature and salinity (and passive tracers)ç
883    o add offline package
884    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
885      provided by Stephanie Dutkiewicz
886    o genmake2: add ability to search for C compilers and cleanup test output
887      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
888    
889    checkpoint54d_post
890    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
891    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
892      leading to additional shift by 5 days each year of integration
893       (i.e. leading to considerable offset over the years)
894    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
895    o start with no AB and no initial filtering (staggerTimeStep):
896      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
897    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
898      (external loading & cpl import/export stay in forward_step.F)
899    o update coupling interface to work with new staggerTimeStep
900    o change MDSIO ptracers_pickup.
901    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
902    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
903    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
904    
905    checkpoint54c_post
906    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
907      this affects (truncation error) output.txt of test-exp:
908       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
909    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
910    o change Qnet to always be the net heat flux, (+upward).
911      affects (truncation error) output of natl_box exp.: updated
912    o define the max number of passive tracers in PTRACERS_SIZE.h
913    o start to test mnc routinely in exp0
914    o add sea-ice loading (sIceLoad) as a new forcing field.
915    
916    checkpoint54b_post
917    o add testreport "-j JOBS" option for parallel builds (tested and pretty
918       impressive on Altix and Opteron systems)
919    o diagnostics can now write NetCDF files through the mnc package
920    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
921    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
922    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
923      affects (truncation error) output of lab_sea & natl_box exp.: updated
924    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
925    
926    checkpoint54a_post
927    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
928    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
929    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
930    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
931      + internal_wave (shift in writing cg2d_ini_res)
932    checkpoint54a_pre
933    
934    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
935      - modified verification/lab_sea and natl_box_adjoint accordingly
936    
937    checkpoint54
938    checkpoint53g_post
939    o prepare splitting of thermodynamics: store convect.counter in common block
940    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
941      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
942    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
943    o new parameter "nShapS": allow to treat differently S from T (nShapT)
944    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
945    o restore adjointability
946    
947    checkpoint53f_post
948    o modifications that affect AIM experiment results (update output.txt):
949      - no advection of S at top interface Nr (pkg/generic_advdiff)
950      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
951    o AIM pkg:
952      - include stability function into surf.Flux derivative relative to Tsurf
953      - calculate clear-sky radiation & surface temp. change (for diagnostics)
954    
955    checkpoint53e_post
956    o merged cylindrical coord configuration
957    o added rotating_tank experiment
958    checkpoint53e_pre
959    
960    checkpoint53d_post
961    o faulks upgraded: re-generate output.txt that have changed:
962       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
963    o Added Bryan and Lewis, 1979, vertical diffusivity profile
964    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
965    o added Sadourny discretization of Coriolis
966      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
967      - re-enabled use of omega3 (useAbsVorticity)
968    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
969      vector-invariant equations
970      - note: does *NOT* yet use same variable visc. for no-slip BC's.
971    o recoded the lateral boundary conditions for non-hydrostatic w, this time
972      hopefully without new bugs
973      - still to do: biharmonic friction for non-hydrostatic w
974    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
975    o regenerated output for global_ocean_ebm (using -ieee)
976    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
977      of mom_common/
978      - simple re-arrangement of instructions within computing loop
979    checkpoint53d_pre
980    
981    checkpoint53c_post
982    o new version of coupler for AIM+thSIce and Ocean models
983     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
984     - land: change Evaporation of snow
985     - aim with thSIce: fix bug in snow-precip.
986    o changes to calc_gw.F
987     - bug fix for w^2 term near the bottom boundary
988     - (hopefully) improve the lateral slip boundary condtions for use with
989        partial/looped cells
990      - because the bug fix changes two verification experiments anyway (exp5
991        and plume on slope), change the lateral boundary condition from half slip
992        to the value of no_slip_sides
993    o ebm package wasnt quite up to the parallel task. Fixed that.
994    o Adjoint of EBM package + verification
995      * TLM OK
996      * ADM not sufficient accuracy yet (needs further testing)
997    
998    checkpoint53b_post
999    o Commiting new energy balance model to repository
1000      * package is pkg/ebm
1001      * verif. is verification/global_ocean_ebm
1002      * references are in ebm_driver.F
1003    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1004    C        Global thermohaline circulation. Part I:
1005    C        Sensitivity to atmospheric moisture transport.
1006    C        J. Climate 12(1), 71-82
1007    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1008    C        Global thermohaline circulation. Part II:
1009    C        Sensitivity with interactive transport.
1010    C        J. Climate 12(1), 83-91
1011    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1012    C        Destabilization of the thermohaline circulation
1013    C        by atmospheric eddy transports.
1014    C        J. Climate 7(12), 1870-1882
1015    o Will need long integration testing.
1016    checkpoint53b_pre
1017    
1018    o created pkg/mom_common in preparation for variable viscosity code
1019    o renamed and split ini_mnc_io
1020    o pkg/land: only liquid water can diffuse or run-off
1021    o AIM using land: soil wetness availability account for snow
1022    o added printMapIncludesZeros to EEPARMS namelist
1023    
1024    checkpoint53a_post
1025    o restore TAMC compatiility for exf_constants.h
1026      (no usage of _d in .h)
1027    o Additional storing in KPP in an attempt to fix
1028      TAMC problem with adjoint of KPP code.
1029      (no success...)
1030      Identical code works fine with TAF.
1031    o Fixed verification/natl_box_adjoint experiments.
1032      Initial conditions for Experiments 4 and 5 are now
1033      set to "SEAICE_initialHEFF=0", which is more reasonable,
1034      and hence gives results closer to that of Experiment 2.
1035      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1036    
1037    checkpoint53
1038    o stable checkpoint with up to date adjoint
1039      TLM tests only run for 1st grdchk at the moment. Its unclear if
1040      this is a code problem or a problem with resetting code for g_
1041      variables that is being autogenerated wrong.
1042      Otherwise:
1043       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1044       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1045         are both still in chaos following their security messes.
1046    
1047    checkpoint52n_post
1048    o various build (mostly genmake2) changes including:
1049      - ability to build/run more easily within Cygwin and MacOS X
1050      - more complicated Makefiles with a stronger dependence on Gnu Make
1051    o pkg/seaice modifications
1052      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1053        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1054        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1055      - changed proxy for geostrophic velocity and updated
1056        verification/lab_sea/results/* accordingly
1057      - removed ADI dynamic solver from pkg/seaice
1058      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1059        they caused a segmentation fault under certain circumstances
1060      - removed unused field WATR
1061    o bug fix in exf-package:
1062      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1063         now reflect that.
1064    o small fixes in the cal-package:
1065      - set reference date to first of January for the 'model'-calendar
1066      - failing of cal_CheckDate in cal_FullDate now actually results in a
1067        warning
1068    o small modifications in exf-package to increase flexibility:
1069      - change climtempfreeze from a constant to a runtime parameter that
1070        is specified in data.exf_clim (default = -1.9)
1071      - introduce runtime parameter windstressmax (default = 2.0) that is
1072        specified in data.exf
1073    o fix in pkg/thsice:
1074      - update Evap (Tsf changes) to be consistent with Latent heat flux
1075      - maintain snow precipitation unchanged (even if Tsf >=0).
1076     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1077    
1078    checkpoint52m_post
1079    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1080      this does not change any of the results, because myIter=0 in swfrac always
1081      lead to jwtype=2 (the default anyway), but the call makes little sense
1082      as a default
1083    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1084    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1085      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1086    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1087    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1088    o extending useSingleCpuIO option to work with new exch2 I/O format
1089      - old-style, missing-tile I/O is still accessible by defining CPP
1090        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1091    o monitor package can write to NetCDF files and/or STDOUT
1092    o fix re-definition bug in MNC_GRID_INIT_ALL()
1093    o doc/api_reference added
1094      - a framework for building an API Reference Manual using all
1095        the "protex" comments embedded in the code
1096      - see pkg/generic_advdiff, pkg/mnc for examples
1097    o MNC:
1098      - make myThid the last argument for all subroutines
1099      - new default for the grid files: NO halos
1100      - add useMNC and other run-time flags
1101      - separate per-file-group handling of the unlimited dimension
1102      - early initialization of MNC w/ flags read at the eeboot stage
1103        and lookup tables set in initialize_fixed
1104      - write all MNC output to a freshly-created directory
1105    o thermodynamics sea-ice (thsice) is now tested with testreport.
1106    o test exp. advect_cs: use the standard cs32 grid ; update output.
1107    o Added functionality to grdchk:
1108      pick global i,j,k position (or nearest wet) where to perform check.
1109    
1110    checkpoint52l_post
1111    o new land formulation:
1112      a) use ground enthalpy as prognostic variable to ensure exact
1113         energy conservation.
1114      b) account for water temperature and for latent heat of freezing
1115         in all processes (rain, run-off, ground storage)
1116      c) compute surface and ground temperature implicitly.
1117    o aim_v23 modification for new land model:
1118      a) Treat separately land / ocean / sea-ice surface fluxes
1119         to allow implicit computation of land & sea-ice surface temp.
1120      b) add snow precipitation.
1121    checkpoint52l_pre

1137    o fixed bug introduced in pkg/monitor
1138    o accuracy ctrlprec = 32 insuffient for gradient checks using
1139      averaged fields (I/O via cost_averages)

1141    o paramter list of CALL ADTHE_MAIN_LOOP
1142    o added initial do_the_model_io to ecco
1143    o set all ...Freq to zero after cost_final

1145    o MAIN and ECCO differentiability restored
1146    
1147    checkpoint52j_post
1148    o fix nchklev in tamc.h for global_ocean...
1149    o Bringing flow and store directives up-to-date
1150    o Really weird thing!
1151      call do_the_model_io from the_main_loop with parameters
1152      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1153      TAF places a faulty re-call of initialise_varia
1154      after cost_final call which should not be there!
1155    checkpoint52j_pre
1156    
1157    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1158      error messages
1159    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1160    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating

1164      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1165    o update AIM Equatorial Channel exp:
1166      use standard aim_v23 pkg and change the SST fields to be more realistic.
1167    o globalFile now works with exch2
1168    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1169      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1170    o limit timeave output for hi-res integrations

1175    checkpoint52i_pre
1176    
1177    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1178      the old pkg/aim).
1179    
1180    checkpoint52h_pre
1181    o shortened offending lines in exch2_send_rx?.template
1182    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator

1185      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1186    o added useSingleCPUIO flag to monitor.F and mon_out.F
1187    o added temporary hack for sea-ice dynamics on the cube:
1188      metric terms are ignored and it is assumed that
1189      there is no sea-ice on cube faces 1, 2, 4, and 5.
1190    
1191    checkpoint52f_post
1192    o added exch2 cube routines to pkg/exch2
1193    o modified hs94.cs-32x32x5 to use it
1194    o added new grid files to hs94.cs-32x32x5
1195    checkpoint52f_pre
1196    
1197    checkpoint52e_post
1198    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1199      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1200    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1201      to work with implicit vertical advection and AB ;
1202    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1203    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1204     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1205    checkpoint52e_pre
1206    
1207    o fix bug in impldiff when Nr=1 or Nr=2.
1208    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1209    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1210    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1211      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1212    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1213    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1214    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1215    
1216    checkpoint52d_post
1217    o re-tiled many expts to allow comparison in multi-processor mode
1218      - updated output accordingly
1219      - changed hs94.128x64x5 to use intial T from file rather than use the
1220        random number generator
1221    o add infrastructure in model routines for fizhi and gridalt packages
1222    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.

1224      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1225      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1226      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1227        of surface winds for the cube
1228      (A verification experiment, based on global_ocean.cs32x15, but with
1229       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1230       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1231       complete with example surface forcing files and matlab scripts to look
1232       at the output and compare it with that of global_ocean.cs32x15.)
1233    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1234       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1235       to conform to the common rule.
1236    o check-in the first version of the coupler + interfaces for multi-components
1237       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1238       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1239       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1240       - ocean and atmos. share the same horizontal grid (no interpolation).
1241       - exchanges between component and coupler is done in forward_step
1242    o new verification experiment, cpl_aim+ocn:
1243       coupled ocean - AIM atmosphere on cs32 grid.
1244    
1245    checkpoint52d_pre
1246    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1247    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1248    
1249    checkpoint52c_post
1250    o Fixing OPTIONS files for use of exf:
1251      - ALLOW_ECCO not needed
1252      - ECCO_CPPOPTIONS.h should not be included from
1253        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1254        as has been the case in the past
1255      - All cal/exf related options are currently set in
1256        single header file. Should remain so until we
1257        agree on a consistent new policy.
1258    o Removed all CPP options for cal package.
1259      cal has no more CPP options.
1260    o modified STOREs in GAD_ADVECTION
1261    o corrected key comp. for passkey
1262    
1263    checkpoint52b_post
1264    o new version: "thsice" of thermodynamic sea-ice pkg:
1265     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1266     - modify fluxes but do not change theta directly;
1267     - light cleaning of bulk_force pkg (still needed with thsice).
1268     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1269       + output_thsice.txt to test thsice & bulk_force pkgs.
1270    o put back grid & coriolis monitor output.
1271    checkpoint52b_pre
1272    
1273    o call "do_the_model_io" at the beginning (=> dump initial state)
1274    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1275    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1276      (need info on NUMBER_OF_PTRACERS)
1277    o missing PTRACERS headers in some routines
1278    o default tamc.h in pkg/autodiff supposed to crash
1279      to ensure proper customization
1280    
1281    checkpoint52a_post
1282    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1283      - moved surfaceTendencyTice from pkg/seaice to main code
1284      - subroutine FREEZE_SURFACE now limits only surface temperature
1285        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1286        => new output.txt for global_ocean.cs32x15 & global_with_exf
1287      - keep the old version of FREEZE for backward compatibility;
1288        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1289      - corresponding modifs for TAF directives
1290    o added surface flux output variables to TIMEAVE_STATVARS

1294      but no warning issued by TAF
1295    
1296    checkpoint52a_pre
1297    o some bug fixes for #undef REAL4_IS_SLOW
1298    
1299    checkpoint52 = ecco_c52_e35
1300    o after testing adjoints of checkpoint51u_post
1301    
1302    checkpoint51u_post
1303    o this is the post-merge tag of the ecco-branch
1304      (needs another clean checkout and re-testing)
1305    o various natl_box_adjoint configs and results
1306      but no input fields
1307    o obcs adjoint not yet merged!
1308    o adding ECCO global 1x1 and 2x2 degree configs
1309    o updated/extended some store directives for seaice
1310    o pkg/ecco now containes ecco-specific part of cost function
1311    o top level routines the_main_loop, forward_step
1312      supersede those in model/src/
1313      previous input data.cost now in data.ecco
1314      (new namelist ecco_cost_nml)
1315    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1316    
1317    checkpoint51t_post
1318    o this is the pre-merge tag of the ecco-branch
1319    
1320    checkpoint51s_post
1321    o cleanup: removed various obsolete #define-s
1322    o pkg/grdchk
1323      - renamed 'ph-grd 3' to 'grad-res'
1324      - merged from ecco-branch
1325        (remaining bug fixes for obcs gradient checks)
1326      - additional high-precision output for testreport
1327        (grep for 'precision_grdchk_result')
1328    
1329    checkpoint51r_post
1330    o cleaned up or removed CPP_OPTIONS.h files
1331    o updated results for some of the tests to reflect the new
1332      optfiles (-ieee: -O0 instead of -O3)
1333    
1334    checkpoint51q_post
1335    o cd_code:
1336      - moved cd_scheme.F -> cd_code_scheme.F
1337      - separate read_checkpoint from cd_code_ini_vars.F
1338      - separated cd_code part from write_checkpoint
1339      - updated AD_SOURCE, generated .flow
1340      - added CD_CODE_VARS.h to the_main_loop

1342    o ctrl package totally restructured
1343      - pack/unpack now optional and decoupled from
1344        xx_/adxx_ I/O
1345      - ctrl_pack/unpack cleaned
1346        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1347      - confined inclusion of AD_CONFIG.h to where necessary.
1348    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1349    
1350    checkpoint51p_post
1351    o create initial cd_code package
1352      - WARNING: the initialization of fields within packages
1353        is broken because INI_FIELDS (where READ_CHECKPOINT is
1354        called) is called *before* PACKAGES_INIT_VARIABLES.
1355        This seems to be backwards since
1356        1) its important to initially zero the entire field including
1357           the "halo" region
1358        2) zeroing needs to be done *before* reading pickup info
1359           and the pickup call might or might not happen in any
1360           particular run
1361      - this needs an overhaul for R2
1362    o cleanup verification/*/code/GMREDI_OPTIONS.h
1363    o cleanup testreport
1364    
1365    checkpoint51o_post

1373    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1374    o bug fix in find_alpha.F for MDJWF:
1375      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1376        change rho -> rho-rhoConst
1377      - replace call find_rho to find_rhonum

1396      - moved surfaceTendencyTice from pkg/seaice to main code
1397      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1398      - subroutine FREEZE now limits only surface temperature
1399        (this means new output.txt for global_ocean.90x40x15,
1400         global_ocean.cs32x15, and global_with_exf)
1401    o added surface flux output variables to TIMEAVE_STATVARS

1426    o enable to apply restoring on S & T only in a latitude band.
1427    o update output (external_forcing_surf modif. change truncation errors)
1428       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
1429    
1430    checkpoint51k_post
1431    o change default to: useNHMTerms=.FALSE.
1432     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):

1509    o AIM : add stratospheric drag in the upper level
1510    
1511    checkpoint51d_post
1512    o change function ILNBLNK (=> last non-blank char.) to return zero
1513      (instead of the string length) when the string. char is empty
1514    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
1515    o modif's to restore TAMC compatibility
1516      - avoid "_d" constructs in PARAMETER declarations
1517      - avoid interrupting lines by comment lines
1518    o Use cluster local disks for purely local I/O
1519      vs. globally visible disks needed for ctrl stuff
1520      (merged from ecco-branch)
1521      - new active_file_loc... and mdsio_..._loc routines
1522      - affected packages: autodiff, ctrl, grdchk, mdsio
1523    
1524    checkpoint51c_post
1525    o introducing integer flag debugLevel
1526      - debLevZero: suppress all output
1527      - debLevA: standard
1528      - debLevB: equivalent to current debugMode=.TRUE.
1529    o introducing pathname variable mdsioLocalDir for mdsio
1530      that can be specified at runtime
1531      (relevant for cluster I/O to local disk)
1532    `
1533    >>>checkpoint51b_post
1534    adjoint of ptracers
1535    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1536    o extended state in checkpoint_lev?, etc.
1537    o alternative ctrl/cost with tr1 or ptracer
1538    o new comlev1_bibj_ptracers
1539    o new ptracers.flow
1540    o made ptracers_forcing same as external_forcing_s
1541    o added verification for adjoint with ptracers
1542      - adm. grdchk fail so far
1543      - tlm. grdchk OK
1544      - checked tapelev/comlev recomputations: OK
1545    <<<checkpoint51b_pre
1546    
1547    checkpoint51a_post
1548    o added code for biogeochemistry package
1549      - new pkgs: dic, gchem
1550      - new subroutine in ptracers
1551    o modify code for biogeo packages
1552      - in model/src and pkg/ptracers
1553    
1554    checkpoint51
1555    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1556      - autodiff, ctrl, exf, grdchk, seaice
1557      kept separate packages
1558      - cost, ecco, obcs
1559    o updating verification/internal_wave, verification/lab_sea
1560      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1561    
1562    checkpoint50i_post
1563    o Preparing next differentiable checkpoint and sync
1564      of MAIN vs. ecco-branch
1565      - 1st step: this one is differentiable
1566      - 2nd step: next(! not this) checkpoint will have updated packages
1567                  from ecco-branch)
1568    
1569    checkpoint50h_post
1570    o new package "land": provide surface BC for AIM.
1571    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1572    o AIM: use true log-P extrapolation for near surface temp (= as in
1573        F.Molteni paper) ; update aim.5l_cs output.
1574    o New variable in PARM03 for more flexible pickups
1575    o somewhat cleaned package initialisation sequence for
1576      ctrl/ cost/ ecco/ in packages_... routines
1577    
1578    checkpoint50g_post
1579    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1580      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1581      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1582        made the default because of faster convergence than ADI
1583    
1584    checkpoint50f_post
1585    o exf totally restructured
1586      - replaced all exf_set_ routines by one generic exf_set_gen.F
1587        and made sure it's still differentiable
1588      - split exf_getffields.F into new exf_bulkformulae.F
1589      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1590      - updated adjoint/makefile and relevant verif. accordingly
1591    
1592    checkpoint50f_pre

1594          + change Evap over land. (update aim.5l_cs output)
1595     o added missing .cvsignores and made uniform across expts
1596     o changed configuration of tidal_basin_2d expt
1597     o added pkg/debug functions for tracing code in fatal crashes

1599     o new fn in pkg/monitor to stop model if solution grows too big
1600     o removed lots of single quotes from comments
1601    
1602    checkpoint50e_post
1603    o make KPP work with PTRACERS
1604     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1605       nearly a copy of kpp_transport_s
1606     - there is no analogue to SurfaceTendencyS, so I have to use
1607       gPtr(of the surface layer) instead
1608    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1609    checkpoint50e_pre
1610    
1611    checkpoint50d_post
1612    o change kpp output from multiple-record state files to single-record state
1613      files analogous to write_state.F
1614    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1615      analogous to the cg2d-related output.
1616    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1617      so that writing to internal file fn (with length 512) fails.
1618    checkpoint50d_pre
1619    
1620    checkpoint50c_post
1621    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1622    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1623    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1624    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1625    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1626    
1627    checkpoint50c_pre
1628    Merging from release1_p13:
1629    o bug fix for pkg/seaice dynamic solver
1630    o Added SEAICE_initialHEFF to pkg/seaice
1631    
1632    checkpoint50b_post
1633    o store u*,v* in gU,V instead of in guNm1,gvNm1
1634    o in order to put the momForcing out of the Adams-Bashforth:
1635      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1636      to timestep.F
1637    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1638    o re-generate output for highly sensitive test-exp:
1639       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1640    
1641    checkpoint50b_pre
1642    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1643    o corrected CPP option mismatch in exf_Bulk... functions for case
1644      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1645    
1646    checkpoint50a_post
1647    o Bug fix for merging between c50 and KPP.
1648      ikey was passed from thermodynamics to kpp_calc via
1649      common block rather than being recomputed in kpp_calc,
1650      in contradiction with new key itdkey.
1651      New key ikppkey created, and tamc.h headers updated.
1652    
1653    checkpoint50
1654    - 2nd step of merge with ecco-branch:
1655      merge changes in ecco-branch back into main trunk
1656    - bug fix in find_alpha
1657    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1658    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1659    - merged some sliced AD support routines
1660    
1661    checkpoint49
1662    merged from ecco-branch:
1663    o exf:
1664      - Enable initialisation of forcing fields to constant
1665        (runtime) values.
1666      - in exf_getffields.F
1667        Reduce i-/j-loop to interior domain, discarding overlaps.
1668        That also fixes wrong TAF-key computations for key_1, key_2
1669        with bulf formulae.
1670      - exf_init.F modify #ifdef for exf_init_evap
1671      - exf_getffieldrec.F, ctrl_getrec.F
1672        The following INT-usages are not safe:
1673          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1674          fldcount = int(fldsecs/fldperiod) + 1
1675        and were modified.
1676    o autodiff: checkpoint_lev...
1677      - updated storing for bulk formulae (some arrays were missing)
1678      - added state for seaice package
1679      - synchronized with main branch
1680    o DIVA:
1681      Modif.s in
1682      - the_main_loop.F
1683      - the_model_main.F
1684      and added cost_final_restore.F cost_final_store.F
1685      o With these changes, it is possible to fully separate
1686        the first forward run to compute the cost function (mdthe_main_loop)
1687        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1688        into separate model executions.
1689        This enables better tuning of DIVA to given queue sizes.
1690      o Loss of cost function value in consecutive DIVA runs is
1691        fixed by storing to 'costfinal' file.
1692      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1693        beginning/end of adjoint integration is accounted for.
1694      The current changes apply to TAF-1.4.26.
1695      TAF has one remaining bug, requiring one manual change
1696      (see MITgcm manual).
1697    o cal: synchronized between MAIN and ecco-branch
1698    
1699    checkpoint48i_post
1700    o Changes to restore differentiability of code w.r.t. previous tag
1701      (mostly adding new routines to make list and replacing
1702      pressure by totPhiHyd).
1703    o Updated and merged grdchk package
1704      - has both ADM and TLM checks
1705      - works for single- and multi-proc.
1706      - output cleaned
1707      - worked successfully for parallel DIVA
1708    o genmake:
1709      - Adding -platform=SP4
1710      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1711    o Modif. for DIVA:
1712      ctrl_unpack should not be called in intermediate DIVA interval.
1713      (similar thing would apply for active files such as
1714      tbar, sbar, psbar, which should not be reinitialised;
1715      only relevant for ecco-branch)
1716    
1717    checkpoint48h_post
1718    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1719    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1720    o Added SEAICE_initialHEFF to pkg/seaice
1721    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1722    
1723    checkpoint48g_post
1724    --- EOS:
1725    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1726      store total Potential in totPhyHyd for diagnostics & EOS.
1727    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1728    --- Pressure/geopotential gradient:
1729    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1730    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1731      ( changes results of global_ocean_pressure )
1732    o NLFS + z-coord.: add eta*Rho' contribution.
1733    o accurate phiHyd when using interface-W at the middle between 2 centers
1734     ( changes results of ideal_2D_oce )
1735    o includes r* 2nd term in potential gradient.
1736    
1737    checkpoint48f_post
1738    Merging from release1_p12:
1739    o Modifications for using pkg/exf with pkg/seaice
1740      - improved description of the various forcing configurations
1741      - added basic radiation bulk formulae to pkg/exf
1742      - units/sign fix for evap computation in exf_getffields.F
1743      - updated verification/global_with_exf/results/output.txt
1744    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1745      (SBO) core products, including oceanic mass, center-of-mass,
1746      angular, and bottom pressure (see pkg/sbo/README.sbo).
1747    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1748      to avoid negative values in shallow regions.
1749      - updated verification/natl_box/results/output.txt
1750      - updated verification/lab_sea/results/output.txt
1751    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1752    o Added useSingleCpuIO option (see PARAMS.h).
1753    o Updated useSingleCpuIO option in mdsio_writefield.F to
1754      work with multi-field files, e.g., for single-file pickup.
1755    o pkg/seaice:
1756      - bug fix in growth.F: QNET for no shortwave case
1757      - added HeffFile for specifying initial sea-ice thickness
1758      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1759    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1760      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1761    o pkg/seaice:
1762      - adjoint-friendly modifications
1763      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1764    
1765    checkpoint48e_post
1766    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1767    o dynamics: change definition of computational domain & adapt mom_fluxform
1768      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1769    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1770        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1771        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1772        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1773        inverted_barometer solid-body.cs-32x32x1
1774      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1775    
1776    checkpoint48d_post
1777    o in preparation for r*:
1778     a) use pre-computed gradient of hydrostatic potential:
1779        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1780     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1781        => affects results of glob_oce_pressure (different truncation error)  
1782      update output.txt of ideal_2D_oce & global_ocean_pressure
1783    
1784    checkpoint48d_pre
1785    o in preparation for r*:
1786      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1787      pass the 2 comp. of the grad. as arguments to momentum S/R.
1788      but for the moment, only used if it does not change the results.
1789    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1790    
1791    checkpoint48c_post
1792    Modifications in treatment of initial flux forcing controls
1793    to avoid extra storing of flux fields.
1794    
1795    checkpoint48c_pre
1796    o Added tidal_basin_2d experiment (currently 1D!)
1797    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1798    
1799  checkpoint48b_post  checkpoint48b_post
1800  o r* coordinate added in #ifdef NONLIN_FRSURF block.  o r* coordinate added in #ifdef NONLIN_FRSURF block.
