5      ==============================      ==============================
6    
7    o shelfice:
8      - separate shelfice load anomaly from pload (breaks with time
9        dependent forcing), => introduce constant field shelficeLoadAnomaly.
10        Its default is 0., but it may be computed more cleverly from (unknown)
11        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
12        done offline. A good approximation of the pressure load anomaly is
13        necessary to avoid large initial adjustment processes underneath
14        deep-reaching shelfice.
15      - small fix in shelfice_thermodynamics
16    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
17      if bulk formulae are used in long integration (especially EmPmR). Turn
18      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
19      if balancePrintMean, the imbalance that is substracted is printed to
20      STDOUT.
21    o fix bug (typo) in obcs_apply_eta.F
22    o add a new package shelfice which enables us to model the circulation
23      underneath shelf-ice with draughts of hundreds of meters.
24     - works
25     - to do: + include improved thermodynamics
26              + check whether kSurfC (from model/inc/SURFACE.h) can be used
27                instead of new field kTopC
28              + can we use topoFile, Ro_surf and existing code in ini_depth.F
29                instead of new field R_shelfIce and new code in ini_depth.F
30                and ini_mask_etc.F?
31              + adjust vertical mixing schemes?
32    o seaice pkg:
33     - add a cpp-flag to include a simple formula for a salinity dependent
34       freezing point of sea water at the surface
35     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
36       meridional stresses are now different (and hopefully correct)
37    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
38       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
39       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
40    o pkg/diagnostics: add options and parameters for regional-statistics
41       diagnostics ; define regions by reading a region-mask from a file
42       (might add other options later)
43    o pkg/bulk_force:
44     - add option and parameters to use AIM surface-flux formulae.
45     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
46       others forcing fields (defined in PARM05, parameter file "data") are loaded
47       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
48     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
49     - use the right EXCH call for uwind,vwind (to work on CS-grid).
50     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
51       and parameters (note: calcWindStress replaces .NOT.readwindstress).
52     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
53    
54    checkpoint58
55    o add "--embed-source" option to genmake2 which, when the supporting
56      tools can be compiled (as determined by genmake2) will turn on the
57      embed_files package which then embeds the entire MITgcm source code
58      (*.[fFhc] + Makefile) used for the build within the executable
59      - requested by CNH but off by default
60      - adds a paltry <9MB to the mitgcmuv executable in most cases
61      - only writes the output when useEMBEDSRC in eedata is true
62    o clean up 3-dim. relaxation codes:
63      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
64      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
65      * Thanks to Tom Haine for testing!
66    
67    checkpoint57z_post
68    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
69      affects output (@ truncation level) of exp. plume_on_slope ; updated.
70    o fix the pickup behavior for obcs in combination with ptracers
71    o fix a bug in ptracers_external_fields_load
72    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
73      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
74    o transfered surface NH pressure to eta field (if exactConserv).
75    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
76         and update lab_sea output.txt file.
77    o completing 3-dim. relaxation code: additional term
78         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
79      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
80      * At compile time, in "EXF_OPTIONS.h" set
81          #define  ALLOW_CLIMTEMP_RELAXATION
82          #define  ALLOW_CLIMSALT_RELAXATION
83      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
84          tauThetaClimRelax3Dim = 15552000.0,
85          tauSaltClimRelax3Dim  = 15552000.0,
86      * 3 cases:
87          1) Use a constant-in-time 3-dim. field
88          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
89          3) Real-time relax. to time-evolving prescribed field
90    o Adding Laplacian-type smoothness constraint on
91      initial and boundary (forcing) controls (ic, bc)
92      * enable at compile-time via
93        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
94      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
95      * Absolute scale somewhat unclear so far
96      * no area weighting was included since no other cost term does so far
97    
98    checkpoint57y_post
99    First step for a NLFS adjoint
100    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
101    o new init. routines for calc_r_star, calc_surf_dr
102    o still need to deal with ini_masks_etc
103    o testreport seemed happy
104    checkpoint57y_pre
105    
106    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
107    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
108    o add new offset feature to offline pkg (plus minor cleanup)
109    o cfc fixes for final year of integration
110    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
111      be in GCHEM_OPTIONS).
112    
113    checkpoint57x_post
114    o fix testreport Pb in multiple test experiment.
115    o cleanup our namelist syntax in verification:
116      - make it more F95 standards compliant (some work still needed)
117      - allows the vast majority of our tests to work with gfortran
118    o Non-Hydrostatic:
119     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
120     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
121    o Allow to apply AB on T,S rather than on AB(gT,gS):
122     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
123     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
124       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
125     - need a "clever" read_pickup to restart from the other AB formulation
126    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
127    o remove some unused variables (reduces number of compiler warnings)
128    o adjoint
129      * Disable useVariableViscosity for adjoint for time being
130        (there are a number of extensive recomputations)
131      * Initialize certain variables needed for adjoint
132    
133    checkpoint57w_post
134    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
135                 fix the singleCpuIO RS version of MDSWRITEFIELD
136       and add a WARNING if using globalFiles=T with multi-processors.
137    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
138      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
139    o tracer advection scheme:
140      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
141       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
142       was not very convenient).
143      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
144       (further tests needed for the implicit DST & Flux-Limiter schemes).
145    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
146      and sRef for convenience, handy, when you want to initialize
147      ptracers in a large domain with a constant non-zero value. Also,
148      untangle ptracers_init.F a little.
149    
150    checkpoint57v_post
151    o change dome exp. to use variable viscosity in side-drag terms.
152    o remove all the files from the cfc_offline test since they are now
153      incorporated into tutorial_cfc_offline which has been producing
154      identical results for a few days of testing
155    o add new parameter: sideDragFactor to enable half-slip-side BC
156      and change side-drag S/R to use viscosity from mom_calc_visc
157      (can switch back by setting sideDragFactor=0.); affects results at
158      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
159       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
160    o vorticity & strain are now computed without masking, to account for
161      no-slip-side BC in variable viscosity calculation ; mask is applied
162      anyway later on, before computing advection/coriolis terms.
163    o modify exp4 to test new obcs support for reading from external files
164      and for passive tracers
165    o fix behavior of ptracers_monitor when monitor output is written to a
166      netcdf-file; still not independent of monitor.F (writes in the same
167      file).
168    o change default value of tRef (put a uniform, meaningful value for ocean
169      & atmos) and initialize sRef (was missing, as Martin mentioned).
170    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
171      to be proportional to enstrophy dissipation length.  Thus,
172       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
173      This is now consistent with Smagorinsky and with the manual.
174    
175    checkpoint57u_post
176    o OBCS and PTRACERS: add open boundary support for passive tracers
177      - either use homogenous (pseudo) v.Neumann conditions or prescribe
178        OB-values from file; this is not different from the way theta and salinity
179        are treated
180      - however, Orlanski-radiation conditions are not supported, and the model
181        will stop if you use pTracers and Orlanski at the same time.
182      - beefed up the rountine obcs_external_fields_load: now only those open
183        boundary values are overwritten with values from files for which there
184        are really files, otherwise the OB-fields remain untouched. This makes
185        it possible to use different OBs at different ends of the domain (as
186        with EXF)
187    o reduce number of exch calls in shap_filt (s2).
188    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
189      truncation level) 4/5 MLAdjust test results (11&12 digits match).
190    
191    checkpoint57t_post
192    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
193    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
194      same truncation, independent of the face number: affects affects several
195      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
196    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
197      note that biharmonic viscosity + no-slip was not tested in any experiment.
198    o fix bug in non-linear free-surf side-drag ; generate new output for
199      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
200    o make mnc honor the writeBinaryPrec flag for most kinds of output
201    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
202    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
203      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
204    o add brackets in multi-terms sum to get same truncation, independent of
205      the face number (manage to get exactly same value of gU,gV at the cs-edge)
206      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
207    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
208      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
209      a maximum grid-scale Reynolds number.  Also, changes all length calculations
210      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
211      Suggested values of viscosity parameters found in mom_calc_visc.
212      Many new viscosity diagnostics available.
213    
214    checkpoint57s_post
215    o Add clearing-house for viscosity calculations, mom_calc_visc and
216      correct numerous bugs in LeithD and Smagorinsky discretizations.  
217      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
218      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
219      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
220      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
221      The Strain-Tension form is now called with useStrainTensonVisc=.true.
222      ViscAhStrain and viscAhTension are now retired.
223    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
224    o In response to JMC's bug report, genmake2 now ignores any soft-links
225      that it finds in the *current* directory when searching for files.
226      Soft-links found in any other source directories will still work as
227      they did before.
228    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
229      a C routine to unlimit the stack size
230    o mnc-ify pkg/aim snapshot vars
231    o mnc-ify pkg/land as requested by Daniel
232    o various changes to mnc including:
233      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
234      - output can now be grouped so that all files within a group
235          change the ITER portion of their names in lock-step together
236      - can now read ("global") PER-FACE (in addition to PER-TILE) files
237          and works with both EXCH1 and EXCH2 (but needs more testing)
238      - writing works for all verification test cases w/ g77 on Linux
239    
240    checkpoint57r_post
241    o make MNC variable initialization happen earlier
242    o add diagnostics for (almost) each term of the momentum Eq.
243    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
244    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
245    o remove MINIMAL_TAVE_OUTPUT option ;
246      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
247    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
248      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
249    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
250    o add time-dependent SST, SSS control
251    o cost terms in ecco/ modularized (new cost_generic.F)
252    o cost_averages routines are modularized (new cost_averagesgeneric.F)
253    o new infrastructure for seaice model vs. obs misfits in seaice/
254      * driver from the_main_loop.F is seaice_cost_driver.F
255      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
256      * gradient check in Exp. 6a of natl_box_adjoint/
257    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
258      (see README file)
259    
260    checkpoint57q_post
261    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
262    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
263      - bug was reported by Jean-Michel and Ian Fenty
264    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
265      update exp. cpl_aim+ocn output.
266    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
267      Needed for high-res. runs with large global files
268      to be able to limit tapelev size
269    o Changed some tests for adjoint:
270      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
271      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
272      * global_ocean.90x40x15/ back to default 3-level checkpointing
273    o Modifications to enable scripted COMMON to MODULE conversion
274      * verification/OpenAD/code/ has necessary scripts and description;
275      * converts, compiles and runs successfully;
276    
277    checkpoint57p_post
278    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
279    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
280      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
281    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
282    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
283      (was already the case for dissipation with mom_vecinv,
284       and also the case for grad.PhiHyd when staggered-timeStep)
285      This will allow to put dissipation out-off the AB time-stepping.
286     Unfortunately, affects truncation error. Update output of exp. that "fails"
287      (cg2d matching number) and leave the others for later: front_relax(10),
288      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
289      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
290    
291    checkpoint57o_post
292    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
293      (2) its ready to be documented during the 20050801 DocFest
294    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
295      for ideal_2D_oce and lab_sea on linux_ia32_g77
296    o set to #undef CTRL_SET_OLD_MAXCVARS_30
297      in global1x1_tot/code_seaice_adj to access indices 32, 33
298      (worth another tag)
299    
300    checkpoint57n_post
301    o adding precip control xx_precip 32
302    o adding swflux control xx_swflux 33
303    o Replacing 10 forcing penalty cost routines by 1 generic.
304    o Implementing partitioning in time-mean and variable adjustment
305      for atmos. state.
306    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
307    o in natl_box_adjoint:
308      * updated exp 1 to 10
309        (but does not have time-mean vs. variable split results yet)
310    o updated global1x1/*_seaice_adj/
311      to incorporate latest changes
312    o enable useSingleCpuIO for mdsio vector routines
313      (applies in particular to tapelev I/O)
314    o removed inefficient K-loop in all active_file*control*.F
315    
316    checkpoint57m_post
317    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
318      and advect_cs (use EXCH-2 and standard cs-32 grid files).
319    o pkg/exch2: filling of face-corner halo regions is optional
320      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
321    
322    checkpoint57l_post
323     tag before updating tutorials (pre-release-2)
324    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
325       for output and interpolation of input fields onto model grid)
326    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
327       Affects results of exp. rotating_tank ; update output.txt.
328    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
329          and taking the square quantity and/or using a fraction-weight field.
330    o fix aim_diagnostics_init.F mate numbers.
331    o add mnc output capability to diagnostics/diagstat and update
332      our cvsignore files for the ACSII output generated
333    
334    checkpoint57k_post
335    o lab_sea now uses diagnostics package and provides a suite of
336      new EXF diagnostics output.
337    
338    checkpoint57j_post
339    o exf
340      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
341        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
342        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
343      * extended diagnostics output
344        - now includes all EXF variables
345        - hs, hl moved to common block
346        - separate S/R for diagnostics, called after ctrl vector is added
347        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
348        - EXFqnet contains true Qnet (i.e. includes qsw)
349      * updated verif. lab_sea, global_with_exf
350      * Rearranging hflux (exf_mapfields -> exf_getforcing)
351        to ensure that diagnostics sees a true EXFqnet
352    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
353    o diagnostics pkg: change pointers so that 1 diagnostic can be used
354      several times with different frequencies.
355    o mnc-ify the thsice package as requested by Daniel Enderton
356      - the monitor--MNC output needs work
357      - many attributes need to be added (most are currently blank)
358    o mnc-ify theaim_v23 package as requested by Daniel Enderton
359      - many attributes need to be added (most are currently blank)
360    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
361    o add Sadourny like discretization to the 4th.O vorticity advection scheme
362    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
363      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
364         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
365    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
366     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
367    
368    checkpoint57i_post
369    o Diagnostics package was changed: diagnostic allocation is now deactivated
370      by setting an empty file name in the namelist (used to be by setting 0 frequency)
371    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
372      add 1rst Order upwind vertical Shear.
373    o add a quick fix for A/B checkpointing in OFFLINE mode
374    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
375      end-run around the C/Fortran linking horror in eesup/src/timers.F
376    o added pkg/runclock: allows user to terminate run based on wall clock
377    o added non-hydrostatic scaling parameter: nh_am2
378    o pkg/my82: futile attempt to make results compiler-independent by adding
379      some "_d 0", etc. no effect.
380    o for mnc output, fill the 'T' coordinate var with myTime and create a
381      separate 'iter' variable for iteration count
382    o pkg/diagnostics:
383      add new capability: output of Global/Regional & per-level statistics ;
384      tested against monitor output (including land & thSIce) on various exp.
385    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
386    
387    checkpoint57h_done
388      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
389      data.diagnostics, data.gchem, data.ptracers) is done.
390    
391    o pkg/diagnostics: prepare for Global/Regional statistics.
392      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
393    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
394      and rename it: DIFFERENT_MULTIPLE
395    
396    checkpoint57h_post
397    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
398    o pkg/diagnostics: change output frequency, now in seconds (instead
399      of Nb of iterations). This requires to change data.diagnostics.
400    checkpoint57h_pre
401    
402    o in mnc, let the user create the output dir if both mnc_outdir_date
403      and mnc_outdir_num are false
404    o add fflags() to pkg/diagnostics which allows one to specify, on a
405      per-file basis, the file precision [default behavior is unchanged]
406    o added diagnostics to pkg/kpp, including computation of mixed layer
407      depth based on a temperature/density criterion
408    o updated verification/natl_box to test the new pkg/kpp diagnostics
409    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
410    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
411    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
412      not mnc -- this mistake was found by JMC and is now corrected
413    
414    checkpoint57g_post
415    o add Adams-Bashforth 3rd Order time stepping:
416      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
417      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
418    checkpoint57g_pre
419    
420    o make lambda[Theta,Salt]ClimRelax spatially varying
421      (default remains spatially uniform constant based on tau)
422    o added new control variables
423      * init. uVel, vVel, etanN
424      * lambda[Theta,Salt]ClimRelax
425    o separate masks used for ctrl_pack/unpack 'from write_grid' output
426      (suggested by G. Forget)
427    
428    checkpoint57f_post
429    o add parameter "baseTime" = model base time = time at iteration zero
430      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
431      account for baseTime shift
432    o move Coriolis arrays from PARAMS.h to GRID.h
433    checkpoint57f_pre
434    
435    o mnc-ifying the seaice package
436    o introduced an alternative length scale calculation for use in the limiting
437      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
438    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
439    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
440      as well as grad(vort3).  Made it compatible with both approximate form
441      for the cubed sphere and full form of these gradients.  Added flag
442      useFullLeith to select between approximate and full form.  
443    o add "d0" in getcon.F to reduce differences between compilers/platforms
444      update output.txt of exp. fizhi-gridalt-hs
445    o change port_rand funtion to allow to set the seed.
446    o fix obscure MNC bug involving conversion between reals and integers
447      - it caused no problems with certain (eg. gcc, ifc) compilers but the
448        new version is now more standards-compliant
449    o adjoint-related modifications
450      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
451      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
452      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
453    
454    checkpoint57e_post
455    o Adding eddy stress controls a la Ferreira et al.
456    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
457    
458    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
459      update output.txt of exp. fizhi-gridalt-hs
460    o add more "Z" dimensions and associated coordinate vars to MNC
461    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
462    o parameter calendarDumps: when set, approximate months (30-31 days) and years
463      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
464      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
465      months and years.  Requires pkg/cal.
466    o diagnostics: add pickup functionality
467      - off by default for backwards compatibility
468      - current version only uses MDSIO -- MNC will be added
469    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
470    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
471    
472    checkpoint57d_post
473    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
474    o modify verification/ideal_2D_oce so that it tests the creation of mnc
475      output from the diagnostics package
476    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
477    o make genmake2 more portable by using ".$FS" instead of ".f" for more
478      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
479    o add coordinate variables to the MNC output from the diagnostics package
480    o change MNC-flags default value: true when useMNC=TRUE
481    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
482      the ability (off by default) to read the grid information using MNC
483    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
484    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
485    o do snap-shot diagnostics at the middle of the time-interval (instead of
486      at the end).
487    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
488      new test for AIM with thSIce + slab-ocean
489    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
490    o move state variable diagnostics to the beginning of the time step ;
491      (note: still needs some work specially for snap-shot diagnostics)
492      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
493    
494    checkpoint57c_post
495    o Change testing option (-ieee) to get closer agreement between g77 & ifort
496    o generate new output.txt files on faulks with g77 & the new -ieee option
497    checkpoint57c_pre
498    
499    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
500      update output.txt of exp. global_ocean.90x40x15
501    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
502      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
503    o add saltFlux(+File) forcing capability with periodicExternalForcing
504    o allow to use pkg diagnostics for GM-Redi & ThSIce output
505    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
506    o improvements for the MNC output from DIAGNOSTICS:
507      - correct handling of the unlimitied dimension
508      - all dims now have associated coordinate variables
509      - variables located at U, V, and Corner ("Z") points are now written
510        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
511        *all* data points are output
512    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
513    o added pkg/seaice/seaice_monitor.F
514    o mdsio_readfield.F can now read files visible only to master MPI process.
515    o pkg/seaice: some test code for ice-modified ocean stress
516    o exf_getffields interpolation defaults to bilinear for all scalar forcing
517      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
518      spurious negative numbers for precipitation and humidity.  Will cause
519      some small numerical differences for integrations using pkg/exf/exf_interp.F.
520    o pkg/ctrl/
521      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
522        May be enabled via doPackDiag
523      *  introduce z-scaling of
524         + gradient (doZscalePack) and
525         + control (doZscaleUnpack)
526    o pkg/mdsio/
527      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
528      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
529    
530    checkpoint57b_post
531    o simplify options in diagnostics_fill arguments (remove weird combinations)
532    o fix MNC coordinate variables so that they now contain per-face index
533      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
534      general, EXCH2 grids are only aligned to a "local" coordinate system
535    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
536    o Implement instantaneous output within pkg diagnostics:
537      setting a negative frequency in data.diagnostics produces
538     "snap-shot" output (as opposed to time-average if freq > 0)
539    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
540      NOTE: change ptracer diagnostics name: use 2 characters to work with
541            more than 9 tracers. Add also diagnostics of advect & diffus flux.
542    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
543      becomes the coordinate variable for the 'T' dimension
544    o add CF-style coordinate variables to MNC
545      - just a first cut:  numbers are meaningless on the cubesphere and
546        missing along the T axis but otherwise it works!
547    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
548    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
549    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
550      this is based directly on what the model compute, so that the content of
551      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
552    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
553    o clean up build options files for SunOS, in particular
554      - remove -traditional from xmakedepend
555      - change -xarch=v9 to -xarch=native for f77
556      - restore use of make (not gmake)
557      - add CC=gcc if using g77
558    o changes per discussion of AM, JMC, & EH3 today:
559      - move redundant "grid" variables out of "state" -- in preparation of
560        creating proper CF-style coordinate variables and in recognition
561        that any/all grid variables can be easily copied (eg. w/NCO) from
562        the grid files into any of the other NetCDF files
563      - *always* output grid variables with MDSIO (this will eventually be
564        changed)
565      - output MNC grid file if useMNC is true
566    o every instance of _END_MASTER() has been found and replaced with
567      _END_MASTER( myThid ) in order to satisfy certain picky Sun
568      preprocessors
569    o re-arrange diagnostics pkg initialisation:
570     - allow each package to extend the available diagnostics list
571     - add some checking and fix small problems (multi-threaded, ...)
572     - new S/R diagnostics_fill (replace fill_diagnostics):
573       look through the short list of active diag. (instead of the long list)
574       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
575    
576    checkpoint57a_post
577    o this set of changes restores TAMC compatibility
578      tested for global_ocean.90x40x15 adjoint on trough
579      (what a pain)
580    
581    checkpoint57a_pre
582    o some modifs in tools/build_options for sunos
583    o call ctrl_pack for ctrl at end for optimcycle=0
584    
585    checkpoint57
586    o add horizontal bi-harmonic viscosity for vertical velocity
587      - new parameter viscA4W (defaults to viscA4)
588      - affects only non-hydrostatic code
589      - to be done: no-slip lateral boundary conditions
590    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
591    o implement Implicit Vertical advection for pTracers
592    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
593      (implemented also for implicit vertical diffusion & advection)
594    o OBCS: extend application of tracer open boundary conditions
595      to a strip beyond the boundary of width Olx/Oly
596    o add call monitor to TAF set of required calls (flow directives)
597      and include in natl_box_adjoint
598    o untangle a few ifdefs related to cost, ctrl, autodiff
599      untangel a few ALLOW_ECCO_OPTIMIZATION
600    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
601      (theta2, salt2 in ecco_cost_weights)
602    
603    checkpoint56c_post
604    o OBCS as control variables
605      - update ctrl_ad_diff.list, obcs_ad_diff.list
606      - remove balance of obcs controls from default
607      - fix index bug nobcs in ctrl_init
608      - fix dummy fields filen in ctrl_pack
609      - add dummy weights for obcs
610    o lsopt: comment out fort.94 output
611    o optim:
612      - remove unnecessary header files
613      - adjusted namelists
614      - add xerbla.F to Makefile
615    o exf:
616      - multiple modifications of exf_check_range
617      - unit change in exf_init_runoff from [m/year] to [m/s]
618    o mdsio:
619      - i/o-vector change debugLevel from debLevA to debLevB
620    
621    checkpoint56b_post
622    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
623      is called from DO_THE_MODEL_IO
624      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
625      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
626      - clean up PTRACERS_WRITE_TIMEAVE a little
627    o add another verification experiment that tests both the cfc-pkg and
628      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
629      reactive tendencies treated inline with regular timestepping
630    o testreport previously did a lousy job of comparing small numbers, so
631      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
632      implemented in the little c-progam tmp_cmpnum.c which is embedded in
633      testreport.
634    o ptracers_monitor: bug fix for MPI
635    
636    checkpoint56a_post
637    o GCHEM: finish reorganizating the package
638      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
639        (introduces another 3D-array for each passive tracer, but only if
640        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
641        gchemTendency is not needed because the timestep is done separately)
642      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
643      - GCHEM is now---more or less cleanly---separate from PTRACERS
644      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
645        so clear to me how that should be done in a general way.
646    o CFC: improve formatting of output in CFC_ATMOS
647    o PTRACERS:
648      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
649        that ALL experiments with ptracers enable can be checked. This makes
650        GCHEM_MONITOR obsolete.
651      - include a runtime parameter PTRACERS_monitorFreq that defaults to
652        monitorFreq
653      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
654    o add PTRACERS (PTR0[1-5]) to testreport output
655    o exf_check_range:
656      * default changed to .TRUE.
657      * will check values for niter0 if debLevA, every timestep if debLevB
658      * STOP in exf_check_range if 'out of range'
659      * range chosen generous to allow for potential extema
660      TBD: a version with stricter range
661           permitted range would be runtime parameters
662    o GMredi:
663      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
664      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
665      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
666    o GCHEM:
667      - move call to GCHEM_FORCING_SEP, so that it is now called before
668        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
669      - introduced a useGCHEM runtime flag and applied it everywhere.
670      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
671        this flag is now only visible within GCHEM-pkg routines.
672      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
673        be replaced by a 3D array that is computed before thermodynamics; for
674        this, the tracer ID iTracer had to be included into the parameter list
675        of ptracers_forcing
676      - set up forward_step to call gchem_forcing, that will replace
677        gchem_forcing_int in ptracers_forcing
678      - cleaning up
679    o small cleaning of exch2: remove files that are also in eesupp/src
680    
681    checkpoint56
682    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
683    o mnc: cleanup "full" files--fixes out-of-memory problem
684    o ECCO-GODAE
685      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
686      * fully merged and updated from SIO code
687        windstress sign change affects
688        - exf_inscal_[u/v]stress
689        - sign of xx_tau[u/v] adjustments
690        - signs in cost_scat
691      * ctrl_get_gen: avoid update of tau[u/v] for first few days
692      * natl_box_adjoint updated and compressed
693      * 2-level checkpoint switch added
694        (tested in EXP. 1 of natl_box_adjoint)
695      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
696    o SVD
697      * first complete, non-hacked version for SVD calculations
698      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
699        performed via direct access files admtlm_vector.it????
700        (via ctrl_[un]pack)
701      * optimcycle is used for ARPACK iteration counter
702        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
703      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
704        and add linear transforms where necessary
705      * controls are initial/final SST, SSS (can be extended; need to check
706        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
707    o mdsio: filename info to both stderr, stdout
708    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
709      from sign change
710    
711    checkpoint55j_post
712    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
713      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
714    o add consistent build directories and .cvsignore files to verification
715    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
716    o make all subroutines 30 or less characters in length for certain older
717      compilers to work (a thorough search only turns up two routines in
718      pkg/ptracers)
719    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
720      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
721    
722    checkpoint55i_post
723    o change arrays for total vertical diffusivity (2.D if explicit,
724      3.D if implicit) ; each ptracer uses its own background value.
725    o added mnc/NetCDF output capability to ocn_compon_interf
726      - added bits to verification/cpl_aim+ocn so that it can run on
727        ITRDA and other clusters without the mpirun "-wd" option
728    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
729      configuration
730    o give MNC the ability to create additional files rather than
731      exceeding a specified file size limit "MNC_MAX_FILESIZE"
732      - the default is just less than 2GB which is a practical limit
733        on many systems
734    o Compute the non-local term using either KPP vertical diffusivity (=default)
735       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
736    
737    checkpoint55h_post
738    o add verification test "vermix"
739    o remove all the *_ioinc flags and replace with the single global
740      outputTypesInclusive flag
741    o allow to set a vertical profile of vertical diffusivity for T & S
742    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
743    o useMNC moved from data.mnc to data.pkg
744    
745    checkpoint55g_post
746    o Renaming carbon AD experiments to comply with testreport conventions
747    o Updating adjoint of Held-Suarez hs94.1x64x5
748    o Fixing directives for non-ECCO forward_step, after ECCO directives
749      have been fixed to avoid recomp. of do_oceanic_phys
750      Works well for global_ocean.90x40x15,
751      but recomp. issue remains for carbon
752    o Updating adjoint output for natl_box_adjoint after
753      pkg/ecco has been modified (see taga c55d_post)
754    
755    checkpoint55f_post
756    o rename to timeave_init_fixed
757    
758    checkpoint55e_post
759    o some delicate re-shuffle of store directives to avoid one
760      extra call of do_oceanic_physics
761      affects ecco_the_main_loop.F, do_oceanic_physics.F
762      checkpoint_lev1_directives.h
763    o NB: this may break global_ocean adjoint temporarily,
764      but it is clear how to fix it. Will do later, need this now.
765    
766    checkpoint55d_post
767    o ECCO specific cost function terms (up-to-date with 1x1 runs)
768    o ecco_cost_weights is modified to 1x1 runs
769    o modifs to allow observations to be read in as
770      single file or yearly files
771    o enable to read exf forcing fields as either
772      single file or yearly files (flag useExfYearlyFields)
773    checkpoint55d_pre
774    
775    o switch between 2-level and 3-level checkpointing
776    o add ability of MNC to write local and "partial" (eg. 2D slices where
777      the full 3D field is never actually stored) arrays to NetCDF files
778      with the correct (that is, the complete multi-dimensional) set of
779      array indicies
780      - used in mom_vecinv() to write the diagFreq output
781      - tested (demonstrated) in verification/aim.5l_cs
782    o further mnc-ification
783      - add verification/lab_sea to the list with mnc setups
784      - fix undefined mnc v-names in cd_code
785      - add kpp to mnc output (both snapshot and timeave)
786    o non-hydrostatic code
787      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
788        in calc_gw.F
789      - defaults to viscAh
790      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
791        friction or Leith) in non-hydrostatic mode, as long as there is
792        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
793    o pkg/cost
794      extend simple cost functions to treat time mean quantities
795      (T,U,V) via cost_accumulate_state from cost_tile
796    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
797        be 2 times larger than the minimum size the advection scheme requires.
798        now get a perfect conservation of salt in advect_cs test-exp (updated)
799    o GGL90 (Gaspar's TKE mixed layer)
800      - add horizontal diffusion of TKE, requires exchanges in
801        do_fields_blocking_exchanges, horizontal diffusivity is zero by
802        default. In OPA there is no horizontal diffusion of TKE but the
803        mixing coefficients are computed from a horizontal average of TKE of
804        6 points or so. I think that diffusion has a little more physical
805        justification.
806      - clean up ggl90_calc in the hope of reducing memory usage (this hope
807        was in vain)
808      - mask tke-variable in ggl90_init
809    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
810    o fix biharmonic diffusion on CS-grid.
811    o more obcs stuff
812      - added obcs_external_fields_load as an alternative to the EXF-pkg option
813        for reading boundary values. This routine is called from
814        obcs_prescribe_read
815      - updated obcs_check
816      - changed sponge layer relaxation parameter units for days to seconds
817      - turned off sponge layer by default
818      - changed argument list of OBCS_CALC to myTime+deltaTclock
819      - fixed about 35 bugs in obcs_external_fields_load
820    
821    checkpoint55c_post
822    o obcs stuff
823      - new runtime flags useOBCSprescribe, useOBCSbalance
824      - re-arranged obcs_calc
825      - moved exf_getobcs to obcs_prescibe_read
826        obcs_prescibe_read is called after ORLANSKI stuff
827        and independent of it (executable can contain all).
828      - updated obcs_check
829      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
830        These may be necessary only if tangential velocities are
831        prescribed at OB, not sure, needs testing.
832    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
833      which simplifies the calls and passes the ifc check-bounds test
834    
835    checkpoint55b_post
836    o add a 2D scalar, Z location, exchange_2 routine.
837    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
838      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
839      affects advect_cs results (for the wrong reason): update output.txt
840    o use a more standard discretization for biharmonic viscosity ;
841     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
842      affects results of dome set-up: update output.txt
843    o fix gad_advection.F (CubedSphere part), back to version 1.23
844    o fix bug in mom_vi_del2uv.F (CubedSphere part).
845    
846    checkpoint55a_post
847    o merged code to
848      * prescribe/read time-dependent open boundaries
849        (works in conjunction with exf, cal)
850      * sponge layer code for open boundaries
851      * each boundary N/S/E/W now has its own CPP option
852        (healthy for the adjoint)
853    
854    checkpoint55
855    o up-to-date adjoint of previous breaks
856      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
857      - global_ocean_ebm: adjoint still needs fix (TLM ok)
858      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
859      - carbon: * remove tr1-related adjoint verification
860                * add ptracer as control variable
861    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
862      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
863    
864    checkpoint54f_post
865    o in verification/carbin/ remove experiment related to
866      ALLOW_PASSIVE_TRACER (array tr1 etc)
867      code_ad/ input_ad/ results_ad
868    
869    o add two new packages
870      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
871        + subject to optimization (memory)
872      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
873        + subject to reordering (many GOTOs in the original code)
874        + so far opps is called for every (i,j) point, and then operates in
875          the vertical; one may want to reorder the scheme in order operate in
876          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
877          fields)
878    o overhaul of IO so that we now have flags for MDSIO and/or MNC
879      - all verification tests compile and run with linux_ia32_g77
880      - defaults are compatible with current input files--nothing
881        should change if you were not previously using MNC
882      - MNC output has been added in numerous places (eg. timeave)
883        but there are still a few writes not yet do-able with MNC
884        (this is in progress)
885      - flags now allow for either/or/both use of MDSIO and MNC and
886        documentation will soon follow
887      - numerous small formatting cleanups for ProTeX
888    o add version info (via BUILD_INFO.h) to MNC and stdout
889    
890    checkpoint54e_post
891    o add two new packages
892      - pp81 (Packanowski and Philander, 1981), Richardson number and
893        stratification dependent mixing
894      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
895      - these scheme operate in a similar manner as KPP (without ghat, of
896        course), however there is only one diffusivity that is used for both
897        temperature and salinity (and passive tracers)ç
898    o add offline package
899    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
900      provided by Stephanie Dutkiewicz
901    o genmake2: add ability to search for C compilers and cleanup test output
902      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
903    
904    checkpoint54d_post
905    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
906    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
907      leading to additional shift by 5 days each year of integration
908       (i.e. leading to considerable offset over the years)
909    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
910    o start with no AB and no initial filtering (staggerTimeStep):
911      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
912    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
913      (external loading & cpl import/export stay in forward_step.F)
914    o update coupling interface to work with new staggerTimeStep
915    o change MDSIO ptracers_pickup.
916    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
917    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
918    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
919    
920    checkpoint54c_post
921    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
922      this affects (truncation error) output.txt of test-exp:
923       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
924    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
925    o change Qnet to always be the net heat flux, (+upward).
926      affects (truncation error) output of natl_box exp.: updated
927    o define the max number of passive tracers in PTRACERS_SIZE.h
928    o start to test mnc routinely in exp0
929    o add sea-ice loading (sIceLoad) as a new forcing field.
930    
931    checkpoint54b_post
932    o add testreport "-j JOBS" option for parallel builds (tested and pretty
933       impressive on Altix and Opteron systems)
934    o diagnostics can now write NetCDF files through the mnc package
935    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
936    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
937    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
938      affects (truncation error) output of lab_sea & natl_box exp.: updated
939    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
940    
941    checkpoint54a_post
942    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
943    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
944    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
945    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
946      + internal_wave (shift in writing cg2d_ini_res)
947    checkpoint54a_pre
948    
949    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
950      - modified verification/lab_sea and natl_box_adjoint accordingly
951    
952    checkpoint54
953    checkpoint53g_post
954    o prepare splitting of thermodynamics: store convect.counter in common block
955    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
956      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
957    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
958    o new parameter "nShapS": allow to treat differently S from T (nShapT)
959    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
960    o restore adjointability
961    
962    checkpoint53f_post
963    o modifications that affect AIM experiment results (update output.txt):
964      - no advection of S at top interface Nr (pkg/generic_advdiff)
965      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
966    o AIM pkg:
967      - include stability function into surf.Flux derivative relative to Tsurf
968      - calculate clear-sky radiation & surface temp. change (for diagnostics)
969    
970    checkpoint53e_post
971    o merged cylindrical coord configuration
972    o added rotating_tank experiment
973    checkpoint53e_pre
974    
975    checkpoint53d_post
976    o faulks upgraded: re-generate output.txt that have changed:
977       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
978    o Added Bryan and Lewis, 1979, vertical diffusivity profile
979    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
980    o added Sadourny discretization of Coriolis
981      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
982      - re-enabled use of omega3 (useAbsVorticity)
983    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
984      vector-invariant equations
985      - note: does *NOT* yet use same variable visc. for no-slip BC's.
986    o recoded the lateral boundary conditions for non-hydrostatic w, this time
987      hopefully without new bugs
988      - still to do: biharmonic friction for non-hydrostatic w
989    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
990    o regenerated output for global_ocean_ebm (using -ieee)
991    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
992      of mom_common/
993      - simple re-arrangement of instructions within computing loop
994    checkpoint53d_pre
995    
996    checkpoint53c_post
997    o new version of coupler for AIM+thSIce and Ocean models
998     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
999     - land: change Evaporation of snow
1000     - aim with thSIce: fix bug in snow-precip.
1001    o changes to calc_gw.F
1002     - bug fix for w^2 term near the bottom boundary
1003     - (hopefully) improve the lateral slip boundary condtions for use with
1004        partial/looped cells
1005      - because the bug fix changes two verification experiments anyway (exp5
1006        and plume on slope), change the lateral boundary condition from half slip
1007        to the value of no_slip_sides
1008    o ebm package wasnt quite up to the parallel task. Fixed that.
1009    o Adjoint of EBM package + verification
1010      * TLM OK
1011      * ADM not sufficient accuracy yet (needs further testing)
1012    
1013    checkpoint53b_post
1014    o Commiting new energy balance model to repository
1015      * package is pkg/ebm
1016      * verif. is verification/global_ocean_ebm
1017      * references are in ebm_driver.F
1018    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1019    C        Global thermohaline circulation. Part I:
1020    C        Sensitivity to atmospheric moisture transport.
1021    C        J. Climate 12(1), 71-82
1022    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1023    C        Global thermohaline circulation. Part II:
1024    C        Sensitivity with interactive transport.
1025    C        J. Climate 12(1), 83-91
1026    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1027    C        Destabilization of the thermohaline circulation
1028    C        by atmospheric eddy transports.
1029    C        J. Climate 7(12), 1870-1882
1030    o Will need long integration testing.
1031    checkpoint53b_pre
1032    
1033    o created pkg/mom_common in preparation for variable viscosity code
1034    o renamed and split ini_mnc_io
1035    o pkg/land: only liquid water can diffuse or run-off
1036    o AIM using land: soil wetness availability account for snow
1037    o added printMapIncludesZeros to EEPARMS namelist
1038    
1039    checkpoint53a_post
1040    o restore TAMC compatiility for exf_constants.h
1041      (no usage of _d in .h)
1042    o Additional storing in KPP in an attempt to fix
1043      TAMC problem with adjoint of KPP code.
1044      (no success...)
1045      Identical code works fine with TAF.
1046    o Fixed verification/natl_box_adjoint experiments.
1047      Initial conditions for Experiments 4 and 5 are now
1048      set to "SEAICE_initialHEFF=0", which is more reasonable,
1049      and hence gives results closer to that of Experiment 2.
1050      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1051    
1052    checkpoint53
1053    o stable checkpoint with up to date adjoint
1054      TLM tests only run for 1st grdchk at the moment. Its unclear if
1055      this is a code problem or a problem with resetting code for g_
1056      variables that is being autogenerated wrong.
1057      Otherwise:
1058       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1059       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1060         are both still in chaos following their security messes.
1061    
1062    checkpoint52n_post
1063    o various build (mostly genmake2) changes including:
1064      - ability to build/run more easily within Cygwin and MacOS X
1065      - more complicated Makefiles with a stronger dependence on Gnu Make
1066    o pkg/seaice modifications
1067      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1068        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1069        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1070      - changed proxy for geostrophic velocity and updated
1071        verification/lab_sea/results/* accordingly
1072      - removed ADI dynamic solver from pkg/seaice
1073      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1074        they caused a segmentation fault under certain circumstances
1075      - removed unused field WATR
1076    o bug fix in exf-package:
1077      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1078         now reflect that.
1079    o small fixes in the cal-package:
1080      - set reference date to first of January for the 'model'-calendar
1081      - failing of cal_CheckDate in cal_FullDate now actually results in a
1082        warning
1083    o small modifications in exf-package to increase flexibility:
1084      - change climtempfreeze from a constant to a runtime parameter that
1085        is specified in data.exf_clim (default = -1.9)
1086      - introduce runtime parameter windstressmax (default = 2.0) that is
1087        specified in data.exf
1088    o fix in pkg/thsice:
1089      - update Evap (Tsf changes) to be consistent with Latent heat flux
1090      - maintain snow precipitation unchanged (even if Tsf >=0).
1091     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1092    
1093    checkpoint52m_post
1094    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1095      this does not change any of the results, because myIter=0 in swfrac always
1096      lead to jwtype=2 (the default anyway), but the call makes little sense
1097      as a default
1098    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1099    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1100      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1101    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1102    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1103    o extending useSingleCpuIO option to work with new exch2 I/O format
1104      - old-style, missing-tile I/O is still accessible by defining CPP
1105        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1106    o monitor package can write to NetCDF files and/or STDOUT
1107    o fix re-definition bug in MNC_GRID_INIT_ALL()
1108    o doc/api_reference added
1109      - a framework for building an API Reference Manual using all
1110        the "protex" comments embedded in the code
1111      - see pkg/generic_advdiff, pkg/mnc for examples
1112    o MNC:

1156    o paramter list of CALL ADTHE_MAIN_LOOP
1157    o added initial do_the_model_io to ecco
1158    o set all ...Freq to zero after cost_final

1162    checkpoint52j_post
1163    o fix nchklev in tamc.h for global_ocean...
1164    o Bringing flow and store directives up-to-date
1165    o Really weird thing!
1166      call do_the_model_io from the_main_loop with parameters
1167      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1168      TAF places a faulty re-call of initialise_varia
1169      after cost_final call which should not be there!
1170    checkpoint52j_pre
1171    
1172    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1173      error messages

1204      there is no sea-ice on cube faces 1, 2, 4, and 5.
1205    
1206    checkpoint52f_post
1207    o added exch2 cube routines to pkg/exch2

1214      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1215    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1216      to work with implicit vertical advection and AB ;
1217    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1218    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1219     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1220    checkpoint52e_pre
1221    
1222    o fix bug in impldiff when Nr=1 or Nr=2.
1223    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1224    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1225    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1226      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1227    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1228    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1229    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1230    
1231    checkpoint52d_post
1232    o re-tiled many expts to allow comparison in multi-processor mode
1233      - updated output accordingly
1234      - changed hs94.128x64x5 to use intial T from file rather than use the
1235        random number generator

1240      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1241      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1242        of surface winds for the cube
1243      (A verification experiment, based on global_ocean.cs32x15, but with
1244       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1245       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1246       complete with example surface forcing files and matlab scripts to look
1247       at the output and compare it with that of global_ocean.cs32x15.)
1248    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1249       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1250       to conform to the common rule.
1251    o check-in the first version of the coupler + interfaces for multi-components
1252       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1253       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1254       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1255       - ocean and atmos. share the same horizontal grid (no interpolation).
1256       - exchanges between component and coupler is done in forward_step
1257    o new verification experiment, cpl_aim+ocn:
1258       coupled ocean - AIM atmosphere on cs32 grid.
1259    
1260    checkpoint52d_pre
1261    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1262    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1263    
1264    checkpoint52c_post
1265    o Fixing OPTIONS files for use of exf:
1266      - ALLOW_ECCO not needed
1267      - ECCO_CPPOPTIONS.h should not be included from
1268        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1269        as has been the case in the past
1270      - All cal/exf related options are currently set in
1271        single header file. Should remain so until we
1272        agree on a consistent new policy.
1273    o Removed all CPP options for cal package.
1274      cal has no more CPP options.
1275    o modified STOREs in GAD_ADVECTION
1276    o corrected key comp. for passkey
1277    
1278    checkpoint52b_post
1279    o new version: "thsice" of thermodynamic sea-ice pkg:
1280     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1281     - modify fluxes but do not change theta directly;
1282     - light cleaning of bulk_force pkg (still needed with thsice).
1283     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1284       + output_thsice.txt to test thsice & bulk_force pkgs.
1285    o put back grid & coriolis monitor output.
1286    checkpoint52b_pre
1287    
1288    o call "do_the_model_io" at the beginning (=> dump initial state)
1289    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1290    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1291      (need info on NUMBER_OF_PTRACERS)
1292    o missing PTRACERS headers in some routines
1293    o default tamc.h in pkg/autodiff supposed to crash
1294      to ensure proper customization
1295    
1296    checkpoint52a_post
1297    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1298      - moved surfaceTendencyTice from pkg/seaice to main code
1299      - subroutine FREEZE_SURFACE now limits only surface temperature
1300        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1301        => new output.txt for global_ocean.cs32x15 & global_with_exf
1302      - keep the old version of FREEZE for backward compatibility;
1303        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1304      - corresponding modifs for TAF directives
1305    o added surface flux output variables to TIMEAVE_STATVARS

1309      but no warning issued by TAF
1310    
1311    checkpoint52a_pre
1312    o some bug fixes for #undef REAL4_IS_SLOW
1313    
1314    checkpoint52 = ecco_c52_e35
1315    o after testing adjoints of checkpoint51u_post
1316    
1317    checkpoint51u_post
1318    o this is the post-merge tag of the ecco-branch
1319      (needs another clean checkout and re-testing)
1320    o various natl_box_adjoint configs and results
1321      but no input fields
1322    o obcs adjoint not yet merged!
1323    o adding ECCO global 1x1 and 2x2 degree configs
1324    o updated/extended some store directives for seaice
1325    o pkg/ecco now containes ecco-specific part of cost function

1329      (new namelist ecco_cost_nml)
1330    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1331    
1332    checkpoint51t_post
1333    o this is the pre-merge tag of the ecco-branch
1334    
1335    checkpoint51s_post
1336    o cleanup: removed various obsolete #define-s
1337    o pkg/grdchk
1338      - renamed 'ph-grd 3' to 'grad-res'
1339      - merged from ecco-branch
1340        (remaining bug fixes for obcs gradient checks)
1341      - additional high-precision output for testreport
1342        (grep for 'precision_grdchk_result')
1343    
1344    checkpoint51r_post
1345    o cleaned up or removed CPP_OPTIONS.h files
1346    o updated results for some of the tests to reflect the new
1347      optfiles (-ieee: -O0 instead of -O3)
1348    
1349    checkpoint51q_post
1350    o cd_code:
1351      - moved cd_scheme.F -> cd_code_scheme.F
1352      - separate read_checkpoint from cd_code_ini_vars.F
1353      - separated cd_code part from write_checkpoint
1354      - updated AD_SOURCE, generated .flow
1355      - added CD_CODE_VARS.h to the_main_loop
1356      - Moving cd_code specific store dir.s to pkg/cd_code
1357    o ctrl package totally restructured
1358      - pack/unpack now optional and decoupled from
1359        xx_/adxx_ I/O
1360      - ctrl_pack/unpack cleaned
1361        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1362      - confined inclusion of AD_CONFIG.h to where necessary.
1363    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1364    
1365    checkpoint51p_post
1366    o create initial cd_code package
1367      - WARNING: the initialization of fields within packages
1368        is broken because INI_FIELDS (where READ_CHECKPOINT is
1369        called) is called *before* PACKAGES_INIT_VARIABLES.
1370        This seems to be backwards since
1371        1) its important to initially zero the entire field including
1372           the "halo" region
1373        2) zeroing needs to be done *before* reading pickup info
1374           and the pickup call might or might not happen in any
1375           particular run
1376      - this needs an overhaul for R2
1377    o cleanup verification/*/code/GMREDI_OPTIONS.h
1378    o cleanup testreport
1379    
1380    checkpoint51o_post

1411      - moved surfaceTendencyTice from pkg/seaice to main code
1412      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1413      - subroutine FREEZE now limits only surface temperature
1414        (this means new output.txt for global_ocean.90x40x15,
1415         global_ocean.cs32x15, and global_with_exf)
1416    o added surface flux output variables to TIMEAVE_STATVARS

1444    
1445    checkpoint51k_post
1446    o change default to: useNHMTerms=.FALSE.

1506        "USE_EXF_INTERPOLATION" to pkg/exf.
1507      - This is a temporary Cartesian-grid hack until
1508        the super-duper ESMF coupler becomes available.
1509      - See verification/global_with_exf/README for usage example.
1510      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
1511        flags and modified pkg/seaice accordingly.
1512    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
1513        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
1514        non-local transport term.
1515    
1516    checkpoint51e_post
1517    o pkg/mom_vecinv:
1518      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)
1519      - add time-ave diagnostic of vorticity advection.
1520    o add diagnostic (instantaneous) of Shapiro Filter effect for T,S & UV.
1521    o atmospheric geopotential: - include water vapor effect;
1522                                - use p^kappa in p* scaling.
1523    o land pkg: read initial state from files.
1524    o AIM : add stratospheric drag in the upper level
1525    
1526    checkpoint51d_post
1527    o change function ILNBLNK (=> last non-blank char.) to return zero
1528      (instead of the string length) when the string. char is empty
1529    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
1530    o modif's to restore TAMC compatibility
1531      - avoid "_d" constructs in PARAMETER declarations
1532      - avoid interrupting lines by comment lines
1533    o Use cluster local disks for purely local I/O
1534      vs. globally visible disks needed for ctrl stuff
1535      (merged from ecco-branch)
1536      - new active_file_loc... and mdsio_..._loc routines
1537      - affected packages: autodiff, ctrl, grdchk, mdsio
1538    
1539    checkpoint51c_post
1540    o introducing integer flag debugLevel
1541      - debLevZero: suppress all output
1542      - debLevA: standard
1543      - debLevB: equivalent to current debugMode=.TRUE.
1544    o introducing pathname variable mdsioLocalDir for mdsio
1545      that can be specified at runtime
1546      (relevant for cluster I/O to local disk)
1547    `
1548    >>>checkpoint51b_post
1549    adjoint of ptracers
1550    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1551    o extended state in checkpoint_lev?, etc.
1552    o alternative ctrl/cost with tr1 or ptracer
1553    o new comlev1_bibj_ptracers
1554    o new ptracers.flow
1555    o made ptracers_forcing same as external_forcing_s
1556    o added verification for adjoint with ptracers
1557      - adm. grdchk fail so far
1558      - tlm. grdchk OK
1559      - checked tapelev/comlev recomputations: OK
1560    <<<checkpoint51b_pre
1561    
1562    checkpoint51a_post
1563    o added code for biogeochemistry package
1564      - new pkgs: dic, gchem
1565      - new subroutine in ptracers
1566    o modify code for biogeo packages
1567      - in model/src and pkg/ptracers
1568    
1569    checkpoint51
1570    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1571      - autodiff, ctrl, exf, grdchk, seaice
1572      kept separate packages
1573      - cost, ecco, obcs
1574    o updating verification/internal_wave, verification/lab_sea
1575      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1576    
1577    checkpoint50i_post
1578    o Preparing next differentiable checkpoint and sync
1579      of MAIN vs. ecco-branch
1580      - 1st step: this one is differentiable
1581      - 2nd step: next(! not this) checkpoint will have updated packages
1582                  from ecco-branch)
1583    
1584    checkpoint50h_post
1585    o new package "land": provide surface BC for AIM.
1586    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1587    o AIM: use true log-P extrapolation for near surface temp (= as in
1588        F.Molteni paper) ; update aim.5l_cs output.
1589    o New variable in PARM03 for more flexible pickups
1590    o somewhat cleaned package initialisation sequence for
1591      ctrl/ cost/ ecco/ in packages_... routines
1592    
1593    checkpoint50g_post
1594    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1595      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1596      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1597        made the default because of faster convergence than ADI
1598    
1599    checkpoint50f_post
1600    o exf totally restructured
1601      - replaced all exf_set_ routines by one generic exf_set_gen.F
1602        and made sure it's still differentiable
1603      - split exf_getffields.F into new exf_bulkformulae.F
1604      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1605      - updated adjoint/makefile and relevant verif. accordingly
1606    
1607    checkpoint50f_pre

1609          + change Evap over land. (update aim.5l_cs output)
1610     o added missing .cvsignores and made uniform across expts
1611     o changed configuration of tidal_basin_2d expt
1612     o added pkg/debug functions for tracing code in fatal crashes

1614     o new fn in pkg/monitor to stop model if solution grows too big
1615     o removed lots of single quotes from comments
1616    
1617    checkpoint50e_post
1618    o make KPP work with PTRACERS
1619     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1620       nearly a copy of kpp_transport_s
1621     - there is no analogue to SurfaceTendencyS, so I have to use
1622       gPtr(of the surface layer) instead
1623    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1624    checkpoint50e_pre
1625    
1626    checkpoint50d_post
1627    o change kpp output from multiple-record state files to single-record state
1628      files analogous to write_state.F
1629    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1630      analogous to the cg2d-related output.
1631    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1632      so that writing to internal file fn (with length 512) fails.
1633    checkpoint50d_pre
1634    
1635    checkpoint50c_post
1636    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1637    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1638    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1639    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1640    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1641    
1642    checkpoint50c_pre
1643    Merging from release1_p13:
1644    o bug fix for pkg/seaice dynamic solver
1645    o Added SEAICE_initialHEFF to pkg/seaice
1646    
1647    checkpoint50b_post
1648    o store u*,v* in gU,V instead of in guNm1,gvNm1
1649    o in order to put the momForcing out of the Adams-Bashforth:
1650      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1651      to timestep.F
1652    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1653    o re-generate output for highly sensitive test-exp:
1654       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1655    
1656    checkpoint50b_pre
1657    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1658    o corrected CPP option mismatch in exf_Bulk... functions for case
1659      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1660    
1661    checkpoint50a_post
1662    o Bug fix for merging between c50 and KPP.
1663      ikey was passed from thermodynamics to kpp_calc via
1664      common block rather than being recomputed in kpp_calc,
1665      in contradiction with new key itdkey.
1666      New key ikppkey created, and tamc.h headers updated.
1667    
1668    checkpoint50
1669    - 2nd step of merge with ecco-branch:
1670      merge changes in ecco-branch back into main trunk
1671    - bug fix in find_alpha
1672    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1673    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1674    - merged some sliced AD support routines
1675    
1676    checkpoint49
1677    merged from ecco-branch:
1678    o exf:
1679      - Enable initialisation of forcing fields to constant
1680        (runtime) values.
1681      - in exf_getffields.F
1682        Reduce i-/j-loop to interior domain, discarding overlaps.
1683        That also fixes wrong TAF-key computations for key_1, key_2
1684        with bulf formulae.
1685      - exf_init.F modify #ifdef for exf_init_evap
1686      - exf_getffieldrec.F, ctrl_getrec.F
1687        The following INT-usages are not safe:
1688          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1689          fldcount = int(fldsecs/fldperiod) + 1
1690        and were modified.
1691    o autodiff: checkpoint_lev...
1692      - updated storing for bulk formulae (some arrays were missing)
1693      - added state for seaice package
1694      - synchronized with main branch
1695    o DIVA:
1696      Modif.s in
1697      - the_main_loop.F
1698      - the_model_main.F
1699      and added cost_final_restore.F cost_final_store.F
1700      o With these changes, it is possible to fully separate
1701        the first forward run to compute the cost function (mdthe_main_loop)
1702        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1703        into separate model executions.
1704        This enables better tuning of DIVA to given queue sizes.
1705      o Loss of cost function value in consecutive DIVA runs is
1706        fixed by storing to 'costfinal' file.
1707      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1708        beginning/end of adjoint integration is accounted for.
1709      The current changes apply to TAF-1.4.26.
1710      TAF has one remaining bug, requiring one manual change
1711      (see MITgcm manual).
1712    o cal: synchronized between MAIN and ecco-branch
1713    
1714    checkpoint48i_post
1715    o Changes to restore differentiability of code w.r.t. previous tag
1716      (mostly adding new routines to make list and replacing
1717      pressure by totPhiHyd).
1718    o Updated and merged grdchk package
1719      - has both ADM and TLM checks
1720      - works for single- and multi-proc.
1721      - output cleaned
1722      - worked successfully for parallel DIVA
1723    o genmake:
1724      - Adding -platform=SP4
1725      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1726    o Modif. for DIVA:
1727      ctrl_unpack should not be called in intermediate DIVA interval.
1728      (similar thing would apply for active files such as
1729      tbar, sbar, psbar, which should not be reinitialised;
1730      only relevant for ecco-branch)
1731    
1732    checkpoint48h_post
1733    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1734    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1735    o Added SEAICE_initialHEFF to pkg/seaice
1736    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1737    
1738    checkpoint48g_post
1739    --- EOS:
1740    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1741      store total Potential in totPhyHyd for diagnostics & EOS.
1742    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1743    --- Pressure/geopotential gradient:
1744    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1745    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1746      ( changes results of global_ocean_pressure )
1747    o NLFS + z-coord.: add eta*Rho' contribution.
1748    o accurate phiHyd when using interface-W at the middle between 2 centers
1749     ( changes results of ideal_2D_oce )
1750    o includes r* 2nd term in potential gradient.
1751    
1752    checkpoint48f_post
1753    Merging from release1_p12:
1754    o Modifications for using pkg/exf with pkg/seaice
1755      - improved description of the various forcing configurations
1756      - added basic radiation bulk formulae to pkg/exf
1757      - units/sign fix for evap computation in exf_getffields.F
1758      - updated verification/global_with_exf/results/output.txt
1759    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1760      (SBO) core products, including oceanic mass, center-of-mass,
1761      angular, and bottom pressure (see pkg/sbo/README.sbo).
1762    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1763      to avoid negative values in shallow regions.
1764      - updated verification/natl_box/results/output.txt
1765      - updated verification/lab_sea/results/output.txt
1766    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1767    o Added useSingleCpuIO option (see PARAMS.h).
1768    o Updated useSingleCpuIO option in mdsio_writefield.F to
1769      work with multi-field files, e.g., for single-file pickup.
1770    o pkg/seaice:
1771      - bug fix in growth.F: QNET for no shortwave case
1772      - added HeffFile for specifying initial sea-ice thickness
1773      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1774    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1775      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1776    o pkg/seaice:
1777      - adjoint-friendly modifications
1778      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1779    
1780    checkpoint48e_post
1781    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1782    o dynamics: change definition of computational domain & adapt mom_fluxform
1783      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1784    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1785        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1786        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1787        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1788        inverted_barometer solid-body.cs-32x32x1
1789      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1790    
1791    checkpoint48d_post
1792    o in preparation for r*:
1793     a) use pre-computed gradient of hydrostatic potential:
1794        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1795     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1796        => affects results of glob_oce_pressure (different truncation error)  
1797      update output.txt of ideal_2D_oce & global_ocean_pressure
1798    
1799    checkpoint48d_pre
1800    o in preparation for r*:
1801      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1802      pass the 2 comp. of the grad. as arguments to momentum S/R.
1803      but for the moment, only used if it does not change the results.
1804    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1805    
1806    checkpoint48c_post
1807    Modifications in treatment of initial flux forcing controls
1808    to avoid extra storing of flux fields.
1809    
1810    checkpoint48c_pre
1811    o Added tidal_basin_2d experiment (currently 1D!)
1812    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1813    
1814    checkpoint48b_post
1815    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1816     (modification to pressure gradient not yet implemented)
1817    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1818      (for U & V) that are used for vertical advection of momentum.
1819    
1820    checkpoint48a_post
1821    o In preparation for r*, use temp. array to compute vertical transport
1822       in flux-form momentum pkg. => change results of few test-exp.
1823      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1824                        lab_sea, natl_box & plume_on_slope
1825    
1826    checkpoint48
1827    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1828    
1829    checkpoint47j_post
1830    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1831    o moved adexch from forward_step to addummy_in_stepping
1832    o added exch in ctrl_map_...
1833    o aveFreq.=0. at end of cost_final to avoid overwrite in
1834      reverse checkpointing loop
1835    o Yet more changes in gmredi:
1836      * adgmredi_calc_tensor
1837        avoiding all recomputation of gmredi_slope_limit
1838      * adgmredi_x/y/rtransport
1839        added flag for excessive storing to avoid recomp. of
1840        u/v/rtans, dTdx/y/z
1841        -> this is not really necessary and very memory-consuming
1842      * adgmredi_slope_psi:
1843        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1844      * gmredi_slope_limit
1845        re-activated full calculation of taperfct for case 'ac02'
1846    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1847    
1848    checkpoint47i_post
1849    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1850    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1851      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1852    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1853    o gmredi: fix few bugs.
1854    
1855    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1856    This will be a good checkpoint to plug into the ecco-branch.
1857    o few modif.'s to get latest version adjointed
1858      (mainly kick out code in ini_linear_phisurf)
1859    o modif's to run adjoint with exactConserv
1860    o case GM_BOLUS_ADVEC should be cleaned
1861      S/R gmredi_slope_psi should be cleaned
1862    o verification/carbon now has exactConserv=.TRUE.
1863    
1864    checkpoint47g_post
1865    o time-average AIM output: becomes independent from statvars time-average
1866      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1867    o After TAF bug fix:
1868      Tested adjoint of gmredi package.
1869      Tests were done with checkpoint47 rather than with latest
1870      checkpoint47f_post since the latter is broken for the adjoint
1871      verification/carbon/ contains both ADM and TLM gradient checks.
1872    Here they are, before they get changed/lost/stolen.
1873    Mostly modif.'s to fix numerical sensitivities.
1874    Gradient checks OK for
1875    - GM_taper_scheme:
1876      * clipping
1877      * ac02
1878      * linear
1879      * glw91
1880      * dm95
1881      * ldd97
1882    - GMREDI_OPTIONS:
1883      * GM_VISBECK_VARIABLE_K
1884      * GM_NON_UNITY_DIAGONAL
1885      * GM_EXTRA_DIAGONAL
1886      * GM_BOLUS_ADVEC
1887    in conjunction with data.gmredi parameters to be checked in
1888    in a few minutes under verification/carbon/code/
1889    
1890    checkpoint47f_post
1891    Merging from release1_p10:
1892    o modifications for using pkg/exf with pkg/seaice
1893      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1894        and SEAICE_EXTERNAL_FLUXES
1895      - pkg/exf CPP options EXF_READ_EVAP and
1896        EXF_NO_BULK_COMPUTATIONS
1897      - usage examples are Experiments 8 and 9 in
1898        verification/lab_sea/README
1899      - verification/lab_sea default experiment now uses
1900        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1901    
1902    checkpoint47e_post
1903    o created a tag prior to creating a branch
1904    
1905    checkpoint47d_post
1906    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1907      at the bottom boundary had an erroneous half slip boundary condition
1908    o added bottom drag and no slip boundary condition capabilities to
1909      oceanic pressure coordinates code
1910    o added new verification experiment global_ocean_pressure, this experiment is
1911      also described in the tutorial section of the manual
1912    checkpoint47d_pre
1913    
1914    checkpoint47c_post
1915    o Added a verification experiment for a global cubed-sphere ocean run
1916      -  verification/global_ocean.cubed32x32x30
1917      -  uses pkg/therm_seaice and pkg/bulk_forcing
1918    
1919    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1920    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1921      when using P-coordinate; only implemented for atmospheric config.
1922    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1923      NOTES: requires option NONLIN_FRSURF to be "#define".
1924    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1925    
1926    checkpoint47b_post
1927    Merging from release1_p9:
1928    o pkg/seaice
1929      - removed GOTO's and added taf directives
1930      - double precision constants to reduce the g77 (Linux)
1931        to F77 (SGI) differences reported in release1_p8
1932    o tools/genmake
1933      - added SGI options
1934    o verification/testscript
1935      - updated to that of checkpoint47a_post
1936    o verification/global_ocean.90x40x15/input/eedata
1937      - modified for SGI f77 compatibility
1938    o verification/lab_sea
1939      - added description of sea-ice model
1940      - added missing matlab routines
1941      - added test of thermodynamics parallelization
1942    
1943    checkpoint47a_post
1944    o new pkg: aim_v23
1945     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1946       for now, keep the same surface forcing as before.
1947     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1948     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1949     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1950    o add diagnostic of surface correction term in monitor output
1951    
1952    o bulk_force and therm_seaice
1953    - Two packages:  bulk_force (Bulk forcing)
1954      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1955    - Earlier integration from Stephaine Dutkiewicz
1956      and Patrick Heimbach.
1957    - Two ifdef statements for compile time,
1958       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1959    
1960    checkpoint47
1961    differentiable version of checkpoint46n_post
1962    o bug fix in quasihydrostaticterms
1963    o * "clean" adjoint code (in terms of extensive recomputations)
1964        can now be obtained for all GMREDI options (i.e. for
1965        - GM_VISBECK_VARIABLE_K
1966        - GM_NON_UNITY_DIAGONAL
1967        - GM_EXTRA_DIAGONAL
1968        - GM_BOLUS_ADVEC )
1969      * However, wrong gradient check problem remains unsolved.
1970      * New CPP options have been introduced for different
1971        tapering schemes
1972    o external_fields_load now part of differentiation list
1973    o pressure needs multiple storing;
1974      would be nice to have store_pressure at beginning or
1975      end of forward_step, e.g. by having phiHyd global (5-dim.)
1976      (NB: pressure is needed for certain cases in find_rho,
1977      which is also invoked through convective_adjustment).
1978    o recomputations in find_rho for cases
1979     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1980    o #define ATMOSPHERIC_LOADING should be differentiable
1981    o ini_forcing shifted to begining of initialise_varia
1982    o Incorporating QNVS line search routines into MITgcm
1983      (this is separate code, and therefore not under pkg)
1984      lsopt/, optim/
1985    o Updated verification/carbon/
1986      - #define GM_VISBECK_VARIABLE_K
1987      - GM_taper_scheme    = 'ldd97'    
1988    
1989    checkpoint46n_post
1990    Merging from release1_p8:
1991    o verification/natl_box:
1992      updating new external_fields_load routine
1993    o New package: pkg/seaice
1994      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1995      The sea-ice code is based on Hibler (1979-1980).
1996      Two sea-ice dynamic solvers, ADI and LSR, are included.
1997      In addition to computing prognostic sea-ice variables and diagnosing
1998      the forcing/external data fields that drive the ocean model,
1999      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
2000      The implied surface heat flux is then stored in variable
2001      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
2002      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
2003      non-local transport term.  Because this call precedes model
2004      thermodynamics, temperature under sea-ice may not be "exactly" at
2005      the freezing point by the time theta is dumped or time-averaged.
2006      N.B.: fairly large differences in accuracy occur across
2007            different platforms/compilers; comparison between
2008            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
2009            generated output gives:
2010       T           S           U           V
2011      C D M    c        m  s        m  s        m  s        m  s

2015    
2016      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
2017    o GAD:
2018      - generated new common blocks to account for call of
2019        same gad routines with differing traceridentities
2020        (needed to modify tracerIdentity indices in GAD.h)
2021      - generated separate common blocks for case useCubedSphereExchange
2022        (Department of Futurology)
2023      - parameter lists to gmredi_?transport: added tracerIdentity
2024      - added new key indices to tamc.h
2025    o external_fields_load:
2026      - added this routine to TAF list
2027      - needed to make some common blocks global and additional storing
2028        along the same lines as exf package (checkpoint_lev?_directives.h)
2029    o exf:
2030      updated external forcing package
2031      - bug fixes carried over from ecco-branch
2032        (missing OBCS_OPTIONS.h in two routines)
2033      - enable easy to use "no forcing".
2034      - added exf I/O for atmospheric loading
2035      - added exf I/O for runoff data
2036      - transfered scaling between exf <-> MITgcm to exf namelist
2037    o Adding new verification experiment global_with_exf.
2038      This verification experiment is almost identical to the
2039      global_ocean.90x40x15 experiment, except that it uses
2040      the exf (and cal) package instead of the
2041      external_fields_load routine (cf README file).
2042    
2043    checkpoint46m_post
2044    o modified testscript to return -- when there are no lines of "%MON" output
2045    o added new flag "quasiHydrostatic" for QH mode
2046      and new routine quasihydrostaticterms()
2047    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2048      New routine: mom_u_coriolis_nh()
2049    o fixed sign of non-hydrostatic metric terms in u and v equations.
2050      Depend on correct sign of gravitySign.
2051    o added work.pc* to .cvsignore in aim directories using ifc
2052    o introduced flag for controllin non-hydrostatic metric terms
2053    o removed gravitySign from PARM04
2054    o switched to g77/ifc from pgf77 in aim experiments
2055    
2056    checkpoint46l_post
2057    o made convective adjustment work with pressure coordinates:
2058     - changed the direction of k-loop in convective_adjustment.F for the
2059       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
2060     - adjusted the reference pressure k-index in convective_adjustment.F
2061     - adjusted the convection condition in convect.F (in analogy to
2062       calc_ivdc.F)
2063     - convective_adjustment no longer computes anything on the halos
2064     - removed the warnings about negative salinity from find_rho.F and
2065       find_alpha.F; instead the new routine look_for_neg_salinity, called
2066       at the beginning of find_rho, find_alpha, and find_beta, does a
2067       check of the entire slice, if CPP-option
2068       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
2069    checkpoint46l_pre
2070    
2071    checkpoint46k_post
2072    o fixed the verification/global_ocean.90x40x15 experiment:
2073     - new bathymetry (the world according to A., JMC, and M.)
2074     - new initial fields and forcing fields (*.bin files)
2075     - new POLY3.COEFFS (for the next release one should switch to a full
2076       equation of state: JMD95P or MDJWF)
2077     - fixed several errors and redundancies in the data file
2078     - experiment uses looped cells
2079     - added matlab directory with diagnostic scripts for plotting of output
2080    
2081    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
2082     - read AIM physics parameters from a file (data.aimphys)
2083     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
2084    
2085    checkpoint46j_post
2086    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
2087    o move wVel computation at the end of the time step, in S/R integr_continuity
2088    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
2089    o update timeave pkg for wVel diagnostic.
2090    checkpoint46j_pre
2091    
2092    checkpoint46i_post
2093    o Clean up AIM package (and keep the results unchanged):
2094      include CPP_OPTION and use IMPLICT NONE in all routines ;
2095      declare all the variables _RL ; use _d 0 for all numerical constants.
2096      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
2097    
2098    checkpoint46h_post
2099    o cleaned up the use of rhoNil and rhoConst.
2100      - rhoNil should only appear in the LINEAR equation of state, everywhere
2101        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
2102        and the dynamical equations are all divided by rhoConst
2103    o introduced new parameter rhoConstFresh, a reference density of fresh
2104      water, to remove the fresh water flux's dependence on rhoNil. The default
2105      value is 999.8 kg/m^3
2106    o cleanup up external_forcing.F and external_forcing_surf.F
2107      - can now be used by both OCEANIC and OCEANICP
2108    checkpoint46h_pre
2109    
2110     Added code to convert surface volume flux (fresh water) into
2111     a mass flux when using P coordinates in the ocean (OCEANICP).
2112     Note: It assumes you have set rho0=rhoConst=density of fresh water.
2113    
2114    checkpoint46g_post
2115    o Include a new diagnostic variable phiHydLow for the ocean model
2116      - in z-coordinates, it is the bottom pressure anomaly
2117      - in p-coordinates, it is the sea surface elevation
2118      - in both cases, these variable have global drift, reflecting the mass
2119        drift in z-coordinates and the volume drift in p-coordinates
2120      - included time averaging for phiHydLow, be aware of the drift!
2121    o depth-dependent computation of Bo_surf for pressure coordinates
2122      in the ocean (buoyancyRelation='OCEANICP')
2123      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2124        Theta, Salinity, and Pressure in the parameter list. This routine is
2125        presently contained in find_rho.F. This routine does not give the
2126        correct density for 'POLY3', which would be a z-dependent reference
2127        density.
2128    o cleaned up find_rho
2129      - removed obsolete 'eqn' from the parameter list.
2130    o added two new verification experiments: gop and goz
2131      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2132    checkpoint46g_pre
2133    
2134    checkpoint46f_post
2135    o Enable tangent linear (forward mode) gradient checks:
2136      - extended active file handling to g_... files
2137      - added TANGENT_SIMULATION to theSimulationMode
2138      - extended grdchk package accordingly
2139    o added tangent linear setup in verification/carbon/code_ftl
2140    o added adjoint setup in verification/front_relax/code_ad
2141    
2142    checkpoint46e_post
2143    o Added new equation of state -> MDJWF
2144      - EOS of McDougall et al., 2002, JAOT, submitted
2145      - caveat: the equation of state is only valid for a smaller (more
2146        realistic?) range of values than JMD95P/Z and UNESCO
2147      - added masks to the calculation of pressure in store_pressure
2148      - added more check values for density in check_eos (ini_eos.F), some of
2149        the old check values are out of the range of the MDJWF-eos, so don't
2150        expect perfect matches for those
2151    checkpoint46e_pre
2152    
2153    checkpoint46d_post
2154    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2155      'OCEANICP', also initialised field pressure correctly in ini_eos in the
2156      case of pressure coordinates. eosType='JMD95Z' in
2157      combination with buoyancyRelation='OCEANICP' now causes an error.
2158    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2159      in find_alpha/beta.
2160    checkpoint46d_pre
2161    
2162    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2163      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
2164    
2165    checkpoint46c_post
2166    o Changes necessary for ocean in p-coordinates
2167     -  Added new buoyancy relation = 'OCEANICP'
2168     -  Added new parameters = gravitySign (this used to be contained inside
2169        the factor dRdZ which I added when we first switched to R coordinates).
2170     X GM/Redi is not compatible (yet)
2171     X bottom drag and no-slip need to be debugged.
2172    checkpoint46c_pre
2173    
2174    checkpoint46b_post
2175    o Added new equation of state -> JMD95Z and JMD95P
2176      - EOS of Jackett and McDougall, 1995, JAOT
2177      - moved all EOS parameters into EOS.h
2178      - new routines ini_eos.F, store_pressure.F
2179    o Added UNESCO EOS, but not recommended because it requires
2180      in-situ temperature (see JMD95)
2181    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2182      unesco.f to be used with POLY3
2183    checkpoint46b_pre
2184    
2185    checkpoint46a_post
2186    o Added (atmospheric) pressure loading
2187      - new field in FFIELDS.h, etc...
2188      - new cpp flag ATMOSPHERIC_LOADING
2189    o Changed hFacC to _hFacC in calc_phi_hyd.F
2190    o Added SHORTWAVE_HEATING to some files for consistency
2191    checkpoint46a_pre
2192    
2193    checkpoint46
2194    further merges from release1_p5
2195    o new ctrl package
2196      - adopted from ECCO environment to enable optimization
2197      - added Eliassen Palm fluxes to controls
2198    o added Eliassen Palm flux controls to gradient check package
2199    o cost package
2200      - Compatible with new ctrl package
2201      - added Eliassen Palm cost hooks
2202      - modif's of existing cost functions
2203    o Adjoint-related bug fixes in kpp:
2204      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
2205      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
2206    o autodiff package
2207      - flow directives:
2208        + new for S/R do_the_model_io
2209        + enhanced for S/R checkpoint
2210        + new gmredi.flow
2211      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
2212        disable adcommon.h/g_common.h by default.
2213      - fixed problem for adjoint of global_max
2214    o modified verification/carbon/
2215    o New setup for adjoint of global_ocean
2216    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
2217    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
2218    o incorporated hooks for sponge layer code (external_forcing.F)
2219    
2220    checkpoint45d_post
2221    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2222    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2223      (affects plume_on_slope "cg2d" output)
2224    o add new parameter deltaTfreesurf for free-surface time stepping
2225    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2226    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
2227    o change phiMin in exp1 (to agree with documentation)
2228    o add new flags:
2229     - T,S forcing inside/outside Adams-Bashforth
2230     - turn off temp,salt advection and/or forcing
2231     - for each tracer, define internal flag for multiDimAdvection & A-B
2232    o monitor: change definition of KE to check conservation of Energy
2233    
2234    checkpoint45c_post
2235    o Removed f90 comments ("!")
2236    o Modified initialisations to enable exf package for MITgcm
2237      (without invoking ECCO_PACKAGE).
2238    o modifications to gradient check package (Martin Losch)
2239      - enable centered differences
2240      - modified format of standard output
2241    
2242    checkpoint45b_post
2243    o cleaned exchange calls in cg2d
2244    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
2245    o included CPP option SINGLE_LAYER_MODE in thermodynamics
2246      to configure barotropic setup (Martin Losch)
2247    o moved some initialisations within bi,bj loop in dynamics
2248      (TAF flow dependency)
2249    o in initialise_varia, moved call packages_init_variables
2250      before convective_adjustment_init
2251      (corresponding adjustment of TAF tape initialisation).
2252    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
2253    
2254    checkpoint45a_post
2255    o compute Rho over the whole domain (extend iMin,jMin indices)
2256    o specific exchange for X-slice domain (case Ny=1)
2257    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
2258    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
2259    
2260    checkpoint44h_post = checkpoint45
2261    o Fix to restore differentiability:
2262      place at which packages_init_variables is called in
2263      initialise_varia is crucial for reverse control flow.
2264    o modifications in GMRedi to enable stable adjoint
2265      (corresponding modif's in thermodynamics, dynamics)
2266    o added missing hook for sponge layer code in external_forcing
2267    o modified test cost functions
2268    o storing in gad_advection (plus removal of write(0,*)!
2269    o missing headers TR1.h added in convective_adjustment routines
2270    o errorMessageUnit set non-equal zero in eeboot
2271      (conflict on some platforms, e.g. IBM SP3)
2272    o modified carbon verif.
2273    
2274    checkpoint44h_pre
2275    o vertical grid option: allow to put the Interface at the middle between
2276      2 cell-centers ; replace delZ in pkg/kpp by drF.
2277    o GM Advective form: Tracers are advected using the residual transport (=
2278      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
2279    
2280    checkpoint44g_post
2281    o fix surface correction term in multiDimAdvection (affects plume_on_slope
2282      results) ; ifdef missing in thermodynamics.F
2283    
2284    checkpoint44f_pre,checkpoint44f_post
2285    o added PTRACERS package
2286      This allows an arbitrary number of passive tracers to be integrated
2287      forward simultaneously with the dynamicaly model.
2288      + Implemented so far:
2289        - basic forward algorithm (time-stepping, advection, diffusion, convection)
2290        - I/O and checkpointing
2291        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
2292      + Not implemented so far:
2293        - KPP
2294        - OBCS
2295      + No specific example supplied (yet) but global_ocean.90x40x15 has the
2296        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
2297        line in data.pkg.
2298      + This package is disabled by default since it increases storage.

2301    o testscript: added -cleanup option
2302    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
2303                 b) enable to filter 2D fields.

2305    checkpoint44e_pre,post
2306    o re-wrote convective adjustment to use pre-calculated weights
2307      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
2308      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
2309      Original calls to convect() still in place.

2311    chkpt44d_pre,post
2312    o added missing EXCLUDE_MONITOR flags
2313    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
2314      (incompatible typ in MIN/MAX expressions caused problems
2315      on IBM SP3)
2316    o in genmake added variable MAKEDEPEND
2317      plus resetting for case SunOS
2318    o added timer_stats.c routine for IBM SP3
2319    o removed variables in dynamics
2320    !!! I forgot to create tag chkpt44d_pre !!!
2321    !!! But chkpt44d_pre = chkpt44c_post    !!!
2322    
2323  o real fresh water flux implemented with non-linear free-surface.  o real fresh water flux implemented with non-linear free-surface.
