5      ==============================      ==============================
6    
7    o Apply mask on Fresh-Water flux (needed for SSH forcing).
8      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
9    o seaice: add runtime flags for turning angles (default to zero)
10    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
11      and trend from exf forcing and ctrl control adjustments
12    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
13      (since checkpoint57x_post)
14    o change the default rotation period to 86164.s = the Earth rotation
15    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
16      and based on a reference stratification. Tested within hs94.cs-32x32x5.
17    o seaice advection: add code for choosing between the default (2nd order
18      central differences) and multiDim advection schemes provided by
19      pkg/generic_advdiff
20    o seaice:
21      - removed all references to SEAICE_GRID.h fields from
22        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
23        (cubed-sphere configuration will change a little)
24      - grid computations in seaice_init are obsolete now.
25      - cleaned up code a little so that is easier to read (hopefully).
26      - added new (better?) discretizations of default advection and diffusion
27        (turn on with SEAICEuseFluxForm)
28      - replace 1 in 3d global fields by kSurface in growth.F
29      
30    checkpoint58a_post
31    o seaice:
32      - bug fix in advect.F
33    o shelfice:
34      - separate shelfice load anomaly from pload (breaks with time
35        dependent forcing), => introduce constant field shelficeLoadAnomaly.
36        Its default is 0., but it may be computed more cleverly from (unknown)
37        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
38        done offline. A good approximation of the pressure load anomaly is
39        necessary to avoid large initial adjustment processes underneath
40        deep-reaching shelfice.
41      - small fix in ISOMIP shelfice_thermodynamics
42      - add more sophisticated thermodynamics of Hellmer (1989), this is
43        now the default
44      - give a few constants more intuitive names
45    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
46      if bulk formulae are used in long integration (especially EmPmR). Turn
47      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
48      if balancePrintMean, the imbalance that is substracted is printed to
49      STDOUT.
50    o fix bug (typo) in obcs_apply_eta.F
51    o add a new package shelfice which enables us to model the circulation
52      underneath shelf-ice with draughts of hundreds of meters.
53     - works
54     - to do: + include improved thermodynamics
55              + check whether kSurfC (from model/inc/SURFACE.h) can be used
56                instead of new field kTopC
57              + can we use topoFile, Ro_surf and existing code in ini_depth.F
58                instead of new field R_shelfIce and new code in ini_depth.F
59                and ini_mask_etc.F?
60              + adjust vertical mixing schemes?
61    o seaice pkg:
62     - add a cpp-flag to include a simple formula for a salinity dependent
63       freezing point of sea water at the surface
64     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
65       meridional stresses are now different (and hopefully correct)
66    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
67       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
68       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
69    o pkg/diagnostics: add options and parameters for regional-statistics
70       diagnostics ; define regions by reading a region-mask from a file
71       (might add other options later)
72    o pkg/bulk_force:
73     - add option and parameters to use AIM surface-flux formulae.
74     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
75       others forcing fields (defined in PARM05, parameter file "data") are loaded
76       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
77     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
78     - use the right EXCH call for uwind,vwind (to work on CS-grid).
79     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
80       and parameters (note: calcWindStress replaces .NOT.readwindstress).
81     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
82    
83    checkpoint58
84    o add "--embed-source" option to genmake2 which, when the supporting
85      tools can be compiled (as determined by genmake2) will turn on the
86      embed_files package which then embeds the entire MITgcm source code
87      (*.[fFhc] + Makefile) used for the build within the executable
88      - requested by CNH but off by default
89      - adds a paltry <9MB to the mitgcmuv executable in most cases
90      - only writes the output when useEMBEDSRC in eedata is true
91    o clean up 3-dim. relaxation codes:
92      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
93      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
94      * Thanks to Tom Haine for testing!
95    
96    checkpoint57z_post
97    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
98      affects output (@ truncation level) of exp. plume_on_slope ; updated.
99    o fix the pickup behavior for obcs in combination with ptracers
100    o fix a bug in ptracers_external_fields_load
101    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
102      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
103    o transfered surface NH pressure to eta field (if exactConserv).
104    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
105         and update lab_sea output.txt file.
106    o completing 3-dim. relaxation code: additional term
107         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
108      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
109      * At compile time, in "EXF_OPTIONS.h" set
110          #define  ALLOW_CLIMTEMP_RELAXATION
111          #define  ALLOW_CLIMSALT_RELAXATION
112      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
113          tauThetaClimRelax3Dim = 15552000.0,
114          tauSaltClimRelax3Dim  = 15552000.0,
115      * 3 cases:
116          1) Use a constant-in-time 3-dim. field
117          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
118          3) Real-time relax. to time-evolving prescribed field
119    o Adding Laplacian-type smoothness constraint on
120      initial and boundary (forcing) controls (ic, bc)
121      * enable at compile-time via
122        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
123      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
124      * Absolute scale somewhat unclear so far
125      * no area weighting was included since no other cost term does so far
126    
127    checkpoint57y_post
128    First step for a NLFS adjoint
129    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
130    o new init. routines for calc_r_star, calc_surf_dr
131    o still need to deal with ini_masks_etc
132    o testreport seemed happy
133    checkpoint57y_pre
134    
135    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
136    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
137    o add new offset feature to offline pkg (plus minor cleanup)
138    o cfc fixes for final year of integration
139    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
140      be in GCHEM_OPTIONS).
141    
142    checkpoint57x_post
143    o fix testreport Pb in multiple test experiment.
144    o cleanup our namelist syntax in verification:
145      - make it more F95 standards compliant (some work still needed)
146      - allows the vast majority of our tests to work with gfortran
147    o Non-Hydrostatic:
148     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
149     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
150    o Allow to apply AB on T,S rather than on AB(gT,gS):
151     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
152     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
153       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
154     - need a "clever" read_pickup to restart from the other AB formulation
155    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
156    o remove some unused variables (reduces number of compiler warnings)
157    o adjoint
158      * Disable useVariableViscosity for adjoint for time being
159        (there are a number of extensive recomputations)
160      * Initialize certain variables needed for adjoint
161    
162    checkpoint57w_post
163    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
164                 fix the singleCpuIO RS version of MDSWRITEFIELD
165       and add a WARNING if using globalFiles=T with multi-processors.
166    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
167      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
168    o tracer advection scheme:
169      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
170       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
171       was not very convenient).
172      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
173       (further tests needed for the implicit DST & Flux-Limiter schemes).
174    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
175      and sRef for convenience, handy, when you want to initialize
176      ptracers in a large domain with a constant non-zero value. Also,
177      untangle ptracers_init.F a little.
178    
179    checkpoint57v_post
180    o change dome exp. to use variable viscosity in side-drag terms.
181    o remove all the files from the cfc_offline test since they are now
182      incorporated into tutorial_cfc_offline which has been producing
183      identical results for a few days of testing
184    o add new parameter: sideDragFactor to enable half-slip-side BC
185      and change side-drag S/R to use viscosity from mom_calc_visc
186      (can switch back by setting sideDragFactor=0.); affects results at
187      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
188       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
189    o vorticity & strain are now computed without masking, to account for
190      no-slip-side BC in variable viscosity calculation ; mask is applied
191      anyway later on, before computing advection/coriolis terms.
192    o modify exp4 to test new obcs support for reading from external files
193      and for passive tracers
194    o fix behavior of ptracers_monitor when monitor output is written to a
195      netcdf-file; still not independent of monitor.F (writes in the same
196      file).
197    o change default value of tRef (put a uniform, meaningful value for ocean
198      & atmos) and initialize sRef (was missing, as Martin mentioned).
199    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
200      to be proportional to enstrophy dissipation length.  Thus,
201       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
202      This is now consistent with Smagorinsky and with the manual.
203    
204    checkpoint57u_post
205    o OBCS and PTRACERS: add open boundary support for passive tracers
206      - either use homogenous (pseudo) v.Neumann conditions or prescribe
207        OB-values from file; this is not different from the way theta and salinity
208        are treated
209      - however, Orlanski-radiation conditions are not supported, and the model
210        will stop if you use pTracers and Orlanski at the same time.
211      - beefed up the rountine obcs_external_fields_load: now only those open
212        boundary values are overwritten with values from files for which there
213        are really files, otherwise the OB-fields remain untouched. This makes
214        it possible to use different OBs at different ends of the domain (as
215        with EXF)
216    o reduce number of exch calls in shap_filt (s2).
217    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
218      truncation level) 4/5 MLAdjust test results (11&12 digits match).
219    
220    checkpoint57t_post
221    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
222    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
223      same truncation, independent of the face number: affects affects several
224      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
225    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
226      note that biharmonic viscosity + no-slip was not tested in any experiment.
227    o fix bug in non-linear free-surf side-drag ; generate new output for
228      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
229    o make mnc honor the writeBinaryPrec flag for most kinds of output
230    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
231    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
232      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
233    o add brackets in multi-terms sum to get same truncation, independent of
234      the face number (manage to get exactly same value of gU,gV at the cs-edge)
235      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
236    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
237      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
238      a maximum grid-scale Reynolds number.  Also, changes all length calculations
239      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
240      Suggested values of viscosity parameters found in mom_calc_visc.
241      Many new viscosity diagnostics available.
242    
243    checkpoint57s_post
244    o Add clearing-house for viscosity calculations, mom_calc_visc and
245      correct numerous bugs in LeithD and Smagorinsky discretizations.  
246      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
247      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
248      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
249      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
250      The Strain-Tension form is now called with useStrainTensonVisc=.true.
251      ViscAhStrain and viscAhTension are now retired.
252    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
253    o In response to JMC's bug report, genmake2 now ignores any soft-links
254      that it finds in the *current* directory when searching for files.
255      Soft-links found in any other source directories will still work as
256      they did before.
257    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
258      a C routine to unlimit the stack size
259    o mnc-ify pkg/aim snapshot vars
260    o mnc-ify pkg/land as requested by Daniel
261    o various changes to mnc including:
262      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
263      - output can now be grouped so that all files within a group
264          change the ITER portion of their names in lock-step together
265      - can now read ("global") PER-FACE (in addition to PER-TILE) files
266          and works with both EXCH1 and EXCH2 (but needs more testing)
267      - writing works for all verification test cases w/ g77 on Linux
268    
269    checkpoint57r_post
270    o make MNC variable initialization happen earlier
271    o add diagnostics for (almost) each term of the momentum Eq.
272    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
273    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
274    o remove MINIMAL_TAVE_OUTPUT option ;
275      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
276    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
277      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
278    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
279    o add time-dependent SST, SSS control
280    o cost terms in ecco/ modularized (new cost_generic.F)
281    o cost_averages routines are modularized (new cost_averagesgeneric.F)
282    o new infrastructure for seaice model vs. obs misfits in seaice/
283      * driver from the_main_loop.F is seaice_cost_driver.F
284      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
285      * gradient check in Exp. 6a of natl_box_adjoint/
286    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
287      (see README file)
288    
289    checkpoint57q_post
290    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
291    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
292      - bug was reported by Jean-Michel and Ian Fenty
293    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
294      update exp. cpl_aim+ocn output.
295    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
296      Needed for high-res. runs with large global files
297      to be able to limit tapelev size
298    o Changed some tests for adjoint:
299      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
300      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
301      * global_ocean.90x40x15/ back to default 3-level checkpointing
302    o Modifications to enable scripted COMMON to MODULE conversion
303      * verification/OpenAD/code/ has necessary scripts and description;
304      * converts, compiles and runs successfully;
305    
306    checkpoint57p_post
307    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
308    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
309      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
310    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
311    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
312      (was already the case for dissipation with mom_vecinv,
313       and also the case for grad.PhiHyd when staggered-timeStep)
314      This will allow to put dissipation out-off the AB time-stepping.
315     Unfortunately, affects truncation error. Update output of exp. that "fails"
316      (cg2d matching number) and leave the others for later: front_relax(10),
317      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
318      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
319    
320    checkpoint57o_post
321    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
322      (2) its ready to be documented during the 20050801 DocFest
323    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
324      for ideal_2D_oce and lab_sea on linux_ia32_g77
325    o set to #undef CTRL_SET_OLD_MAXCVARS_30
326      in global1x1_tot/code_seaice_adj to access indices 32, 33
327      (worth another tag)
328    
329    checkpoint57n_post
330    o adding precip control xx_precip 32
331    o adding swflux control xx_swflux 33
332    o Replacing 10 forcing penalty cost routines by 1 generic.
333    o Implementing partitioning in time-mean and variable adjustment
334      for atmos. state.
335    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
336    o in natl_box_adjoint:
337      * updated exp 1 to 10
338        (but does not have time-mean vs. variable split results yet)
339    o updated global1x1/*_seaice_adj/
340      to incorporate latest changes
341    o enable useSingleCpuIO for mdsio vector routines
342      (applies in particular to tapelev I/O)
343    o removed inefficient K-loop in all active_file*control*.F
344    
345    checkpoint57m_post
346    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
347      and advect_cs (use EXCH-2 and standard cs-32 grid files).
348    o pkg/exch2: filling of face-corner halo regions is optional
349      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
350    
351    checkpoint57l_post
352     tag before updating tutorials (pre-release-2)
353    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
354       for output and interpolation of input fields onto model grid)
355    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
356       Affects results of exp. rotating_tank ; update output.txt.
357    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
358          and taking the square quantity and/or using a fraction-weight field.
359    o fix aim_diagnostics_init.F mate numbers.
360    o add mnc output capability to diagnostics/diagstat and update
361      our cvsignore files for the ACSII output generated
362    
363    checkpoint57k_post
364    o lab_sea now uses diagnostics package and provides a suite of
365      new EXF diagnostics output.
366    
367    checkpoint57j_post
368    o exf
369      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
370        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
371        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
372      * extended diagnostics output
373        - now includes all EXF variables
374        - hs, hl moved to common block
375        - separate S/R for diagnostics, called after ctrl vector is added
376        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
377        - EXFqnet contains true Qnet (i.e. includes qsw)
378      * updated verif. lab_sea, global_with_exf
379      * Rearranging hflux (exf_mapfields -> exf_getforcing)
380        to ensure that diagnostics sees a true EXFqnet
381    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
382    o diagnostics pkg: change pointers so that 1 diagnostic can be used
383      several times with different frequencies.
384    o mnc-ify the thsice package as requested by Daniel Enderton
385      - the monitor--MNC output needs work
386      - many attributes need to be added (most are currently blank)
387    o mnc-ify theaim_v23 package as requested by Daniel Enderton
388      - many attributes need to be added (most are currently blank)
389    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
390    o add Sadourny like discretization to the 4th.O vorticity advection scheme
391    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
392      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
393         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
394    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
395     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
396    
397    checkpoint57i_post
398    o Diagnostics package was changed: diagnostic allocation is now deactivated
399      by setting an empty file name in the namelist (used to be by setting 0 frequency)
400    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
401      add 1rst Order upwind vertical Shear.
402    o add a quick fix for A/B checkpointing in OFFLINE mode
403    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
404      end-run around the C/Fortran linking horror in eesup/src/timers.F
405    o added pkg/runclock: allows user to terminate run based on wall clock
406    o added non-hydrostatic scaling parameter: nh_am2
407    o pkg/my82: futile attempt to make results compiler-independent by adding
408      some "_d 0", etc. no effect.
409    o for mnc output, fill the 'T' coordinate var with myTime and create a
410      separate 'iter' variable for iteration count
411    o pkg/diagnostics:
412      add new capability: output of Global/Regional & per-level statistics ;
413      tested against monitor output (including land & thSIce) on various exp.
414    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
415    
416    checkpoint57h_done
417      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
418      data.diagnostics, data.gchem, data.ptracers) is done.
419    
420    o pkg/diagnostics: prepare for Global/Regional statistics.
421      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
422    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
423      and rename it: DIFFERENT_MULTIPLE
424    
425    checkpoint57h_post
426    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
427    o pkg/diagnostics: change output frequency, now in seconds (instead
428      of Nb of iterations). This requires to change data.diagnostics.
429    checkpoint57h_pre
430    
431    o in mnc, let the user create the output dir if both mnc_outdir_date
432      and mnc_outdir_num are false
433    o add fflags() to pkg/diagnostics which allows one to specify, on a
434      per-file basis, the file precision [default behavior is unchanged]
435    o added diagnostics to pkg/kpp, including computation of mixed layer
436      depth based on a temperature/density criterion
437    o updated verification/natl_box to test the new pkg/kpp diagnostics
438    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
439    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
440    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
441      not mnc -- this mistake was found by JMC and is now corrected
442    
443    checkpoint57g_post
444    o add Adams-Bashforth 3rd Order time stepping:
445      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
446      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
447    checkpoint57g_pre
448    
449    o make lambda[Theta,Salt]ClimRelax spatially varying
450      (default remains spatially uniform constant based on tau)
451    o added new control variables
452      * init. uVel, vVel, etanN
453      * lambda[Theta,Salt]ClimRelax
454    o separate masks used for ctrl_pack/unpack 'from write_grid' output
455      (suggested by G. Forget)
456    
457    checkpoint57f_post
458    o add parameter "baseTime" = model base time = time at iteration zero
459      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
460      account for baseTime shift
461    o move Coriolis arrays from PARAMS.h to GRID.h
462    checkpoint57f_pre
463    
464    o mnc-ifying the seaice package
465    o introduced an alternative length scale calculation for use in the limiting
466      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
467    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
468    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
469      as well as grad(vort3).  Made it compatible with both approximate form
470      for the cubed sphere and full form of these gradients.  Added flag
471      useFullLeith to select between approximate and full form.  
472    o add "d0" in getcon.F to reduce differences between compilers/platforms
473      update output.txt of exp. fizhi-gridalt-hs
474    o change port_rand funtion to allow to set the seed.
475    o fix obscure MNC bug involving conversion between reals and integers
476      - it caused no problems with certain (eg. gcc, ifc) compilers but the
477        new version is now more standards-compliant
478    o adjoint-related modifications
479      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
480      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
481      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
482    
483    checkpoint57e_post
484    o Adding eddy stress controls a la Ferreira et al.
485    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
486    
487    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
488      update output.txt of exp. fizhi-gridalt-hs
489    o add more "Z" dimensions and associated coordinate vars to MNC
490    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
491    o parameter calendarDumps: when set, approximate months (30-31 days) and years
492      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
493      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
494      months and years.  Requires pkg/cal.
495    o diagnostics: add pickup functionality
496      - off by default for backwards compatibility
497      - current version only uses MDSIO -- MNC will be added
498    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
499    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
500    
501    checkpoint57d_post
502    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
503    o modify verification/ideal_2D_oce so that it tests the creation of mnc
504      output from the diagnostics package
505    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
506    o make genmake2 more portable by using ".$FS" instead of ".f" for more
507      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
508    o add coordinate variables to the MNC output from the diagnostics package
509    o change MNC-flags default value: true when useMNC=TRUE
510    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
511      the ability (off by default) to read the grid information using MNC
512    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
513    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
514    o do snap-shot diagnostics at the middle of the time-interval (instead of
515      at the end).
516    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
517      new test for AIM with thSIce + slab-ocean
518    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
519    o move state variable diagnostics to the beginning of the time step ;
520      (note: still needs some work specially for snap-shot diagnostics)
521      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
522    
523    checkpoint57c_post
524    o Change testing option (-ieee) to get closer agreement between g77 & ifort
525    o generate new output.txt files on faulks with g77 & the new -ieee option
526    checkpoint57c_pre
527    
528    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
529      update output.txt of exp. global_ocean.90x40x15
530    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
531      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
532    o add saltFlux(+File) forcing capability with periodicExternalForcing
533    o allow to use pkg diagnostics for GM-Redi & ThSIce output
534    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
535    o improvements for the MNC output from DIAGNOSTICS:
536      - correct handling of the unlimitied dimension
537      - all dims now have associated coordinate variables
538      - variables located at U, V, and Corner ("Z") points are now written
539        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
540        *all* data points are output
541    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
542    o added pkg/seaice/seaice_monitor.F
543    o mdsio_readfield.F can now read files visible only to master MPI process.
544    o pkg/seaice: some test code for ice-modified ocean stress
545    o exf_getffields interpolation defaults to bilinear for all scalar forcing
546      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
547      spurious negative numbers for precipitation and humidity.  Will cause
548      some small numerical differences for integrations using pkg/exf/exf_interp.F.
549    o pkg/ctrl/
550      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
551        May be enabled via doPackDiag
552      *  introduce z-scaling of
553         + gradient (doZscalePack) and
554         + control (doZscaleUnpack)
555    o pkg/mdsio/
556      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
557      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
558    
559    checkpoint57b_post
560    o simplify options in diagnostics_fill arguments (remove weird combinations)
561    o fix MNC coordinate variables so that they now contain per-face index
562      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
563      general, EXCH2 grids are only aligned to a "local" coordinate system
564    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
565    o Implement instantaneous output within pkg diagnostics:
566      setting a negative frequency in data.diagnostics produces
567     "snap-shot" output (as opposed to time-average if freq > 0)
568    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
569      NOTE: change ptracer diagnostics name: use 2 characters to work with
570            more than 9 tracers. Add also diagnostics of advect & diffus flux.
571    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
572      becomes the coordinate variable for the 'T' dimension
573    o add CF-style coordinate variables to MNC
574      - just a first cut:  numbers are meaningless on the cubesphere and
575        missing along the T axis but otherwise it works!
576    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
577    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
578    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
579      this is based directly on what the model compute, so that the content of
580      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
581    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
582    o clean up build options files for SunOS, in particular
583      - remove -traditional from xmakedepend
584      - change -xarch=v9 to -xarch=native for f77
585      - restore use of make (not gmake)
586      - add CC=gcc if using g77
587    o changes per discussion of AM, JMC, & EH3 today:
588      - move redundant "grid" variables out of "state" -- in preparation of
589        creating proper CF-style coordinate variables and in recognition
590        that any/all grid variables can be easily copied (eg. w/NCO) from
591        the grid files into any of the other NetCDF files
592      - *always* output grid variables with MDSIO (this will eventually be
593        changed)
594      - output MNC grid file if useMNC is true
595    o every instance of _END_MASTER() has been found and replaced with
596      _END_MASTER( myThid ) in order to satisfy certain picky Sun
597      preprocessors
598    o re-arrange diagnostics pkg initialisation:
599     - allow each package to extend the available diagnostics list
600     - add some checking and fix small problems (multi-threaded, ...)
601     - new S/R diagnostics_fill (replace fill_diagnostics):
602       look through the short list of active diag. (instead of the long list)
603       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
604    
605    checkpoint57a_post
606    o this set of changes restores TAMC compatibility
607      tested for global_ocean.90x40x15 adjoint on trough
608      (what a pain)
609    
610    checkpoint57a_pre
611    o some modifs in tools/build_options for sunos
612    o call ctrl_pack for ctrl at end for optimcycle=0
613    
614    checkpoint57
615    o add horizontal bi-harmonic viscosity for vertical velocity
616      - new parameter viscA4W (defaults to viscA4)
617      - affects only non-hydrostatic code
618      - to be done: no-slip lateral boundary conditions
619    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
620    o implement Implicit Vertical advection for pTracers
621    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
622      (implemented also for implicit vertical diffusion & advection)
623    o OBCS: extend application of tracer open boundary conditions
624      to a strip beyond the boundary of width Olx/Oly
625    o add call monitor to TAF set of required calls (flow directives)
626      and include in natl_box_adjoint
627    o untangle a few ifdefs related to cost, ctrl, autodiff
628      untangel a few ALLOW_ECCO_OPTIMIZATION
629    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
630      (theta2, salt2 in ecco_cost_weights)
631    
632    checkpoint56c_post
633    o OBCS as control variables
634      - update ctrl_ad_diff.list, obcs_ad_diff.list
635      - remove balance of obcs controls from default
636      - fix index bug nobcs in ctrl_init
637      - fix dummy fields filen in ctrl_pack
638      - add dummy weights for obcs
639    o lsopt: comment out fort.94 output
640    o optim:
641      - remove unnecessary header files
642      - adjusted namelists
643      - add xerbla.F to Makefile
644    o exf:
645      - multiple modifications of exf_check_range
646      - unit change in exf_init_runoff from [m/year] to [m/s]
647    o mdsio:
648      - i/o-vector change debugLevel from debLevA to debLevB
649    
650    checkpoint56b_post
651    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
652      is called from DO_THE_MODEL_IO
653      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
654      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
655      - clean up PTRACERS_WRITE_TIMEAVE a little
656    o add another verification experiment that tests both the cfc-pkg and
657      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
658      reactive tendencies treated inline with regular timestepping
659    o testreport previously did a lousy job of comparing small numbers, so
660      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
661      implemented in the little c-progam tmp_cmpnum.c which is embedded in
662      testreport.
663    o ptracers_monitor: bug fix for MPI
664    
665    checkpoint56a_post
666    o GCHEM: finish reorganizating the package
667      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
668        (introduces another 3D-array for each passive tracer, but only if
669        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
670        gchemTendency is not needed because the timestep is done separately)
671      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
672      - GCHEM is now---more or less cleanly---separate from PTRACERS
673      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
674        so clear to me how that should be done in a general way.
675    o CFC: improve formatting of output in CFC_ATMOS
676    o PTRACERS:
677      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
678        that ALL experiments with ptracers enable can be checked. This makes
679        GCHEM_MONITOR obsolete.
680      - include a runtime parameter PTRACERS_monitorFreq that defaults to
681        monitorFreq
682      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
683    o add PTRACERS (PTR0[1-5]) to testreport output
684    o exf_check_range:
685      * default changed to .TRUE.
686      * will check values for niter0 if debLevA, every timestep if debLevB
687      * STOP in exf_check_range if 'out of range'
688      * range chosen generous to allow for potential extema
689      TBD: a version with stricter range
690           permitted range would be runtime parameters
691    o GMredi:
692      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
693      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
694      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
695    o GCHEM:
696      - move call to GCHEM_FORCING_SEP, so that it is now called before
697        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
698      - introduced a useGCHEM runtime flag and applied it everywhere.
699      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
700        this flag is now only visible within GCHEM-pkg routines.
701      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
702        be replaced by a 3D array that is computed before thermodynamics; for
703        this, the tracer ID iTracer had to be included into the parameter list
704        of ptracers_forcing
705      - set up forward_step to call gchem_forcing, that will replace
706        gchem_forcing_int in ptracers_forcing
707      - cleaning up
708    o small cleaning of exch2: remove files that are also in eesupp/src
709    
710    checkpoint56
711    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
712    o mnc: cleanup "full" files--fixes out-of-memory problem
713    o ECCO-GODAE
714      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
715      * fully merged and updated from SIO code
716        windstress sign change affects
717        - exf_inscal_[u/v]stress
718        - sign of xx_tau[u/v] adjustments
719        - signs in cost_scat
720      * ctrl_get_gen: avoid update of tau[u/v] for first few days
721      * natl_box_adjoint updated and compressed
722      * 2-level checkpoint switch added
723        (tested in EXP. 1 of natl_box_adjoint)
724      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
725    o SVD
726      * first complete, non-hacked version for SVD calculations
727      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
728        performed via direct access files admtlm_vector.it????
729        (via ctrl_[un]pack)
730      * optimcycle is used for ARPACK iteration counter
731        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
732      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
733        and add linear transforms where necessary
734      * controls are initial/final SST, SSS (can be extended; need to check
735        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
736    o mdsio: filename info to both stderr, stdout
737    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
738      from sign change
739    
740    checkpoint55j_post
741    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
742      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
743    o add consistent build directories and .cvsignore files to verification
744    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
745    o make all subroutines 30 or less characters in length for certain older
746      compilers to work (a thorough search only turns up two routines in
747      pkg/ptracers)
748    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
749      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
750    
751    checkpoint55i_post
752    o change arrays for total vertical diffusivity (2.D if explicit,
753      3.D if implicit) ; each ptracer uses its own background value.
754    o added mnc/NetCDF output capability to ocn_compon_interf
755      - added bits to verification/cpl_aim+ocn so that it can run on
756        ITRDA and other clusters without the mpirun "-wd" option
757    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
758      configuration
759    o give MNC the ability to create additional files rather than
760      exceeding a specified file size limit "MNC_MAX_FILESIZE"
761      - the default is just less than 2GB which is a practical limit
762        on many systems
763    o Compute the non-local term using either KPP vertical diffusivity (=default)
764       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
765    
766    checkpoint55h_post
767    o add verification test "vermix"
768    o remove all the *_ioinc flags and replace with the single global
769      outputTypesInclusive flag
770    o allow to set a vertical profile of vertical diffusivity for T & S
771    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
772    o useMNC moved from data.mnc to data.pkg
773    
774    checkpoint55g_post
775    o Renaming carbon AD experiments to comply with testreport conventions
776    o Updating adjoint of Held-Suarez hs94.1x64x5
777    o Fixing directives for non-ECCO forward_step, after ECCO directives
778      have been fixed to avoid recomp. of do_oceanic_phys
779      Works well for global_ocean.90x40x15,
780      but recomp. issue remains for carbon
781    o Updating adjoint output for natl_box_adjoint after
782      pkg/ecco has been modified (see taga c55d_post)
783    
784    checkpoint55f_post
785    o rename to timeave_init_fixed
786    
787    checkpoint55e_post
788    o some delicate re-shuffle of store directives to avoid one
789      extra call of do_oceanic_physics
790      affects ecco_the_main_loop.F, do_oceanic_physics.F
791      checkpoint_lev1_directives.h
792    o NB: this may break global_ocean adjoint temporarily,
793      but it is clear how to fix it. Will do later, need this now.
794    
795    checkpoint55d_post
796    o ECCO specific cost function terms (up-to-date with 1x1 runs)
797    o ecco_cost_weights is modified to 1x1 runs
798    o modifs to allow observations to be read in as
799      single file or yearly files
800    o enable to read exf forcing fields as either
801      single file or yearly files (flag useExfYearlyFields)
802    checkpoint55d_pre
803    
804    o switch between 2-level and 3-level checkpointing
805    o add ability of MNC to write local and "partial" (eg. 2D slices where
806      the full 3D field is never actually stored) arrays to NetCDF files
807      with the correct (that is, the complete multi-dimensional) set of
808      array indicies
809      - used in mom_vecinv() to write the diagFreq output
810      - tested (demonstrated) in verification/aim.5l_cs
811    o further mnc-ification
812      - add verification/lab_sea to the list with mnc setups
813      - fix undefined mnc v-names in cd_code
814      - add kpp to mnc output (both snapshot and timeave)
815    o non-hydrostatic code
816      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
817        in calc_gw.F
818      - defaults to viscAh
819      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
820        friction or Leith) in non-hydrostatic mode, as long as there is
821        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
822    o pkg/cost
823      extend simple cost functions to treat time mean quantities
824      (T,U,V) via cost_accumulate_state from cost_tile
825    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
826        be 2 times larger than the minimum size the advection scheme requires.
827        now get a perfect conservation of salt in advect_cs test-exp (updated)
828    o GGL90 (Gaspar's TKE mixed layer)
829      - add horizontal diffusion of TKE, requires exchanges in
830        do_fields_blocking_exchanges, horizontal diffusivity is zero by
831        default. In OPA there is no horizontal diffusion of TKE but the
832        mixing coefficients are computed from a horizontal average of TKE of
833        6 points or so. I think that diffusion has a little more physical
834        justification.
835      - clean up ggl90_calc in the hope of reducing memory usage (this hope
836        was in vain)
837      - mask tke-variable in ggl90_init
838    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
839    o fix biharmonic diffusion on CS-grid.
840    o more obcs stuff
841      - added obcs_external_fields_load as an alternative to the EXF-pkg option
842        for reading boundary values. This routine is called from
843        obcs_prescribe_read
844      - updated obcs_check
845      - changed sponge layer relaxation parameter units for days to seconds
846      - turned off sponge layer by default
847      - changed argument list of OBCS_CALC to myTime+deltaTclock
848      - fixed about 35 bugs in obcs_external_fields_load
849    
850    checkpoint55c_post
851    o obcs stuff
852      - new runtime flags useOBCSprescribe, useOBCSbalance
853      - re-arranged obcs_calc
854      - moved exf_getobcs to obcs_prescibe_read
855        obcs_prescibe_read is called after ORLANSKI stuff
856        and independent of it (executable can contain all).
857      - updated obcs_check
858      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
859        These may be necessary only if tangential velocities are
860        prescribed at OB, not sure, needs testing.
861    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
862      which simplifies the calls and passes the ifc check-bounds test
863    
864    checkpoint55b_post
865    o add a 2D scalar, Z location, exchange_2 routine.
866    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
867      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
868      affects advect_cs results (for the wrong reason): update output.txt
869    o use a more standard discretization for biharmonic viscosity ;
870     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
871      affects results of dome set-up: update output.txt
872    o fix gad_advection.F (CubedSphere part), back to version 1.23
873    o fix bug in mom_vi_del2uv.F (CubedSphere part).
874    
875    checkpoint55a_post
876    o merged code to
877      * prescribe/read time-dependent open boundaries
878        (works in conjunction with exf, cal)
879      * sponge layer code for open boundaries
880      * each boundary N/S/E/W now has its own CPP option
881        (healthy for the adjoint)
882    
883    checkpoint55
884    o up-to-date adjoint of previous breaks
885      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
886      - global_ocean_ebm: adjoint still needs fix (TLM ok)
887      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
888      - carbon: * remove tr1-related adjoint verification
889                * add ptracer as control variable
890    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
891      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
892    
893    checkpoint54f_post
894    o in verification/carbin/ remove experiment related to
895      ALLOW_PASSIVE_TRACER (array tr1 etc)
896      code_ad/ input_ad/ results_ad
897    
898    o add two new packages
899      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
900        + subject to optimization (memory)
901      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
902        + subject to reordering (many GOTOs in the original code)
903        + so far opps is called for every (i,j) point, and then operates in
904          the vertical; one may want to reorder the scheme in order operate in
905          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
906          fields)
907    o overhaul of IO so that we now have flags for MDSIO and/or MNC
908      - all verification tests compile and run with linux_ia32_g77
909      - defaults are compatible with current input files--nothing
910        should change if you were not previously using MNC
911      - MNC output has been added in numerous places (eg. timeave)
912        but there are still a few writes not yet do-able with MNC
913        (this is in progress)
914      - flags now allow for either/or/both use of MDSIO and MNC and
915        documentation will soon follow
916      - numerous small formatting cleanups for ProTeX
917    o add version info (via BUILD_INFO.h) to MNC and stdout
918    
919    checkpoint54e_post
920    o add two new packages
921      - pp81 (Packanowski and Philander, 1981), Richardson number and
922        stratification dependent mixing
923      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
924      - these scheme operate in a similar manner as KPP (without ghat, of
925        course), however there is only one diffusivity that is used for both
926        temperature and salinity (and passive tracers)ç
927    o add offline package
928    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
929      provided by Stephanie Dutkiewicz
930    o genmake2: add ability to search for C compilers and cleanup test output
931      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
932    
933    checkpoint54d_post
934    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
935    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
936      leading to additional shift by 5 days each year of integration
937       (i.e. leading to considerable offset over the years)
938    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
939    o start with no AB and no initial filtering (staggerTimeStep):
940      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
941    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
942      (external loading & cpl import/export stay in forward_step.F)
943    o update coupling interface to work with new staggerTimeStep
944    o change MDSIO ptracers_pickup.
945    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
946    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
947    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
948    
949    checkpoint54c_post
950    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
951      this affects (truncation error) output.txt of test-exp:
952       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
953    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
954    o change Qnet to always be the net heat flux, (+upward).
955      affects (truncation error) output of natl_box exp.: updated
956    o define the max number of passive tracers in PTRACERS_SIZE.h
957    o start to test mnc routinely in exp0
958    o add sea-ice loading (sIceLoad) as a new forcing field.
959    
960    checkpoint54b_post
961    o add testreport "-j JOBS" option for parallel builds (tested and pretty
962       impressive on Altix and Opteron systems)
963    o diagnostics can now write NetCDF files through the mnc package
964    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
965    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
966    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
967      affects (truncation error) output of lab_sea & natl_box exp.: updated
968    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
969    
970    checkpoint54a_post
971    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
972    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
973    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
974    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
975      + internal_wave (shift in writing cg2d_ini_res)
976    checkpoint54a_pre
977    
978    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
979      - modified verification/lab_sea and natl_box_adjoint accordingly
980    
981    checkpoint54
982    checkpoint53g_post
983    o prepare splitting of thermodynamics: store convect.counter in common block
984    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
985      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
986    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
987    o new parameter "nShapS": allow to treat differently S from T (nShapT)
988    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
989    o restore adjointability
990    
991    checkpoint53f_post
992    o modifications that affect AIM experiment results (update output.txt):
993      - no advection of S at top interface Nr (pkg/generic_advdiff)
994      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
995    o AIM pkg:
996      - include stability function into surf.Flux derivative relative to Tsurf
997      - calculate clear-sky radiation & surface temp. change (for diagnostics)
998    
999    checkpoint53e_post
1000    o merged cylindrical coord configuration
1001    o added rotating_tank experiment
1002    checkpoint53e_pre
1003    
1004    checkpoint53d_post
1005    o faulks upgraded: re-generate output.txt that have changed:
1006       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1007    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1008    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1009    o added Sadourny discretization of Coriolis
1010      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1011      - re-enabled use of omega3 (useAbsVorticity)
1012    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1013      vector-invariant equations
1014      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1015    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1016      hopefully without new bugs
1017      - still to do: biharmonic friction for non-hydrostatic w
1018    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1019    o regenerated output for global_ocean_ebm (using -ieee)
1020    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1021      of mom_common/
1022      - simple re-arrangement of instructions within computing loop
1023    checkpoint53d_pre
1024    
1025    checkpoint53c_post
1026    o new version of coupler for AIM+thSIce and Ocean models
1027     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1028     - land: change Evaporation of snow
1029     - aim with thSIce: fix bug in snow-precip.
1030    o changes to calc_gw.F
1031     - bug fix for w^2 term near the bottom boundary
1032     - (hopefully) improve the lateral slip boundary condtions for use with
1033        partial/looped cells
1034      - because the bug fix changes two verification experiments anyway (exp5
1035        and plume on slope), change the lateral boundary condition from half slip
1036        to the value of no_slip_sides
1037    o ebm package wasnt quite up to the parallel task. Fixed that.
1038    o Adjoint of EBM package + verification
1039      * TLM OK
1040      * ADM not sufficient accuracy yet (needs further testing)
1041    
1042    checkpoint53b_post
1043    o Commiting new energy balance model to repository
1044      * package is pkg/ebm
1045      * verif. is verification/global_ocean_ebm
1046      * references are in ebm_driver.F
1047    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1048    C        Global thermohaline circulation. Part I:
1049    C        Sensitivity to atmospheric moisture transport.
1050    C        J. Climate 12(1), 71-82
1051    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1052    C        Global thermohaline circulation. Part II:
1053    C        Sensitivity with interactive transport.
1054    C        J. Climate 12(1), 83-91
1055    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1056    C        Destabilization of the thermohaline circulation
1057    C        by atmospheric eddy transports.
1058    C        J. Climate 7(12), 1870-1882
1059    o Will need long integration testing.
1060    checkpoint53b_pre
1061    
1062    o created pkg/mom_common in preparation for variable viscosity code
1063    o renamed and split ini_mnc_io
1064    o pkg/land: only liquid water can diffuse or run-off
1065    o AIM using land: soil wetness availability account for snow
1066    o added printMapIncludesZeros to EEPARMS namelist
1067    
1068    checkpoint53a_post
1069    o restore TAMC compatiility for exf_constants.h
1070      (no usage of _d in .h)
1071    o Additional storing in KPP in an attempt to fix
1072      TAMC problem with adjoint of KPP code.
1073      (no success...)
1074      Identical code works fine with TAF.
1075    o Fixed verification/natl_box_adjoint experiments.
1076      Initial conditions for Experiments 4 and 5 are now
1077      set to "SEAICE_initialHEFF=0", which is more reasonable,
1078      and hence gives results closer to that of Experiment 2.
1079      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1080    
1081    checkpoint53
1082    o stable checkpoint with up to date adjoint
1083      TLM tests only run for 1st grdchk at the moment. Its unclear if
1084      this is a code problem or a problem with resetting code for g_
1085      variables that is being autogenerated wrong.
1086      Otherwise:
1087       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1088       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1089         are both still in chaos following their security messes.
1090    
1091    checkpoint52n_post
1092    o various build (mostly genmake2) changes including:
1093      - ability to build/run more easily within Cygwin and MacOS X
1094      - more complicated Makefiles with a stronger dependence on Gnu Make
1095    o pkg/seaice modifications
1096      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1097        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1098        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1099      - changed proxy for geostrophic velocity and updated
1100        verification/lab_sea/results/* accordingly
1101      - removed ADI dynamic solver from pkg/seaice
1102      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1103        they caused a segmentation fault under certain circumstances
1104      - removed unused field WATR
1105    o bug fix in exf-package:
1106      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1107         now reflect that.
1108    o small fixes in the cal-package:
1109      - set reference date to first of January for the 'model'-calendar
1110      - failing of cal_CheckDate in cal_FullDate now actually results in a
1111        warning
1112    o small modifications in exf-package to increase flexibility:
1113      - change climtempfreeze from a constant to a runtime parameter that
1114        is specified in data.exf_clim (default = -1.9)
1115      - introduce runtime parameter windstressmax (default = 2.0) that is
1116        specified in data.exf
1117    o fix in pkg/thsice:
1118      - update Evap (Tsf changes) to be consistent with Latent heat flux
1119      - maintain snow precipitation unchanged (even if Tsf >=0).
1120     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1121    
1122    checkpoint52m_post
1123    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1124      this does not change any of the results, because myIter=0 in swfrac always
1125      lead to jwtype=2 (the default anyway), but the call makes little sense
1126      as a default
1127    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1128    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1129      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1130    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1131    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1132    o extending useSingleCpuIO option to work with new exch2 I/O format
1133      - old-style, missing-tile I/O is still accessible by defining CPP
1134        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1135    o monitor package can write to NetCDF files and/or STDOUT
1136    o fix re-definition bug in MNC_GRID_INIT_ALL()
1137    o doc/api_reference added
1138      - a framework for building an API Reference Manual using all
1139        the "protex" comments embedded in the code
1140      - see pkg/generic_advdiff, pkg/mnc for examples
1141    o MNC:
1142      - make myThid the last argument for all subroutines
1143      - new default for the grid files: NO halos
1144      - add useMNC and other run-time flags
1145      - separate per-file-group handling of the unlimited dimension
1146      - early initialization of MNC w/ flags read at the eeboot stage
1147        and lookup tables set in initialize_fixed
1148      - write all MNC output to a freshly-created directory
1149    o thermodynamics sea-ice (thsice) is now tested with testreport.
1150    o test exp. advect_cs: use the standard cs32 grid ; update output.
1151    o Added functionality to grdchk:
1152      pick global i,j,k position (or nearest wet) where to perform check.
1153    
1154    checkpoint52l_post
1155    o new land formulation:
1156      a) use ground enthalpy as prognostic variable to ensure exact
1157         energy conservation.
1158      b) account for water temperature and for latent heat of freezing
1159         in all processes (rain, run-off, ground storage)
1160      c) compute surface and ground temperature implicitly.
1161    o aim_v23 modification for new land model:
1162      a) Treat separately land / ocean / sea-ice surface fluxes
1163         to allow implicit computation of land & sea-ice surface temp.
1164      b) add snow precipitation.
1165    checkpoint52l_pre
1166    
1167    o fix problem (when 1 tile is empty) in min/max monitor.

1176    o exf: Adding simple range check routine for exf fields after read
1177    
1178    checkpoint52k_post
1179    o removed top-level directory "diags"
1180      - we migrated these functions to pkg/timeave a long time ago
1181    o fixed bug introduced in pkg/monitor
1182    o accuracy ctrlprec = 32 insuffient for gradient checks using
1183      averaged fields (I/O via cost_averages)
1184      -> use ctrl.h in active_file*.F to control I/O precision.
1185    o paramter list of CALL ADTHE_MAIN_LOOP
1186    o added initial do_the_model_io to ecco
1187    o set all ...Freq to zero after cost_final
1188      taveFreq, dumpFreq, pChkptFreq
1189    o MAIN and ECCO differentiability restored
1190    
1191    checkpoint52j_post
1192    o fix nchklev in tamc.h for global_ocean...
1193    o Bringing flow and store directives up-to-date
1194    o Really weird thing!
1195      call do_the_model_io from the_main_loop with parameters
1196      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1197      TAF places a faulty re-call of initialise_varia
1198      after cost_final call which should not be there!
1199    checkpoint52j_pre
1200    
1201    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1202      error messages
1203    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1204    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1205      debug output
1206    o modfied mdsio_writefield.F to handle non-global files under exch2
1207    o update AIM Cubed-Sphere exp (aim.5l_cs):
1208      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1209    o update AIM Equatorial Channel exp:
1210      use standard aim_v23 pkg and change the SST fields to be more realistic.
1211    o globalFile now works with exch2
1212    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1213      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1214    o limit timeave output for hi-res integrations
1215    
1216    checkpoint52i_post
1217    o removed CPP_EEOPTIONS.h from verification/*/code
1218    o updated the tiling for global_ocean_pressure
1219    checkpoint52i_pre
1220    
1221    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1222      the old pkg/aim).
1223    
1224    checkpoint52h_pre
1225    o shortened offending lines in exch2_send_rx?.template
1226    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1227    o genmake2: add build & execute test for NetCDF code
1228    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1229      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1230    o added useSingleCPUIO flag to monitor.F and mon_out.F
1231    o added temporary hack for sea-ice dynamics on the cube:
1232      metric terms are ignored and it is assumed that
1233      there is no sea-ice on cube faces 1, 2, 4, and 5.
1234    
1235    checkpoint52f_post
1236    o added exch2 cube routines to pkg/exch2
1237    o modified hs94.cs-32x32x5 to use it
1238    o added new grid files to hs94.cs-32x32x5
1239    checkpoint52f_pre
1240    
1241    checkpoint52e_post
1242    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1243      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1244    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1245      to work with implicit vertical advection and AB ;
1246    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1247    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1248     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1249    checkpoint52e_pre
1250    
1251    o fix bug in impldiff when Nr=1 or Nr=2.
1252    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1253    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1254    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1255      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1256    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1257    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1258    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1259    
1260    checkpoint52d_post
1261    o re-tiled many expts to allow comparison in multi-processor mode
1262      - updated output accordingly
1263      - changed hs94.128x64x5 to use intial T from file rather than use the
1264        random number generator
1265    o add infrastructure in model routines for fizhi and gridalt packages
1266    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1267    o changes to permit hi-res, cubed-sphere, configuration
1268      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1269      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1270      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1271        of surface winds for the cube
1272      (A verification experiment, based on global_ocean.cs32x15, but with
1273       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1274       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1275       complete with example surface forcing files and matlab scripts to look
1276       at the output and compare it with that of global_ocean.cs32x15.)
1277    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1278       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1279       to conform to the common rule.
1280    o check-in the first version of the coupler + interfaces for multi-components
1281       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1282       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1283       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1284       - ocean and atmos. share the same horizontal grid (no interpolation).
1285       - exchanges between component and coupler is done in forward_step
1286    o new verification experiment, cpl_aim+ocn:
1287       coupled ocean - AIM atmosphere on cs32 grid.
1288    
1289    checkpoint52d_pre
1290    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1291    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1292    
1293    checkpoint52c_post
1294    o Fixing OPTIONS files for use of exf:
1295      - ALLOW_ECCO not needed
1296      - ECCO_CPPOPTIONS.h should not be included from
1297        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1298        as has been the case in the past
1299      - All cal/exf related options are currently set in
1300        single header file. Should remain so until we
1301        agree on a consistent new policy.
1302    o Removed all CPP options for cal package.
1303      cal has no more CPP options.
1304    o modified STOREs in GAD_ADVECTION
1305    o corrected key comp. for passkey
1306    
1307    checkpoint52b_post
1308    o new version: "thsice" of thermodynamic sea-ice pkg:
1309     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1310     - modify fluxes but do not change theta directly;
1311     - light cleaning of bulk_force pkg (still needed with thsice).
1312     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1313       + output_thsice.txt to test thsice & bulk_force pkgs.
1314    o put back grid & coriolis monitor output.
1315    checkpoint52b_pre
1316    
1317    o call "do_the_model_io" at the beginning (=> dump initial state)
1318    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1319    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1320      (need info on NUMBER_OF_PTRACERS)
1321    o missing PTRACERS headers in some routines
1322    o default tamc.h in pkg/autodiff supposed to crash
1323      to ensure proper customization
1324    
1325    checkpoint52a_post
1326    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1327      - moved surfaceTendencyTice from pkg/seaice to main code
1328      - subroutine FREEZE_SURFACE now limits only surface temperature
1329        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1330        => new output.txt for global_ocean.cs32x15 & global_with_exf
1331      - keep the old version of FREEZE for backward compatibility;
1332        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1333      - corresponding modifs for TAF directives
1334    o added surface flux output variables to TIMEAVE_STATVARS
1335    o time-averaged output for pkg/ptracers
1336    o fix problem with ECCO-related divided adjoint
1337      snapshot file was missing some ad-variables,
1338      but no warning issued by TAF
1339    
1340    checkpoint52a_pre
1341    o some bug fixes for #undef REAL4_IS_SLOW
1342    
1343    checkpoint52 = ecco_c52_e35
1344    o after testing adjoints of checkpoint51u_post
1345    
1346    checkpoint51u_post
1347    o this is the post-merge tag of the ecco-branch
1348      (needs another clean checkout and re-testing)
1349    o various natl_box_adjoint configs and results
1350      but no input fields
1351    o obcs adjoint not yet merged!
1352    o adding ECCO global 1x1 and 2x2 degree configs
1353    o updated/extended some store directives for seaice
1354    o pkg/ecco now containes ecco-specific part of cost function
1355    o top level routines the_main_loop, forward_step
1356      supersede those in model/src/
1357      previous input data.cost now in data.ecco
1358      (new namelist ecco_cost_nml)
1359    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1360    
1361    checkpoint51t_post
1362    o this is the pre-merge tag of the ecco-branch
1363    
1364    checkpoint51s_post
1365    o cleanup: removed various obsolete #define-s
1366    o pkg/grdchk
1367      - renamed 'ph-grd 3' to 'grad-res'
1368      - merged from ecco-branch
1369        (remaining bug fixes for obcs gradient checks)
1370      - additional high-precision output for testreport
1371        (grep for 'precision_grdchk_result')
1372    
1373    checkpoint51r_post
1374    o cleaned up or removed CPP_OPTIONS.h files
1375    o updated results for some of the tests to reflect the new
1376      optfiles (-ieee: -O0 instead of -O3)
1377    
1378    checkpoint51q_post
1379    o cd_code:
1380      - moved cd_scheme.F -> cd_code_scheme.F
1381      - separate read_checkpoint from cd_code_ini_vars.F
1382      - separated cd_code part from write_checkpoint
1383      - updated AD_SOURCE, generated .flow
1384      - added CD_CODE_VARS.h to the_main_loop
1385      - Moving cd_code specific store dir.s to pkg/cd_code
1386    o ctrl package totally restructured
1387      - pack/unpack now optional and decoupled from
1388        xx_/adxx_ I/O
1389      - ctrl_pack/unpack cleaned
1390        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1391      - confined inclusion of AD_CONFIG.h to where necessary.
1392    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1393    
1394    checkpoint51p_post
1395    o create initial cd_code package
1396      - WARNING: the initialization of fields within packages
1397        is broken because INI_FIELDS (where READ_CHECKPOINT is
1398        called) is called *before* PACKAGES_INIT_VARIABLES.
1399        This seems to be backwards since
1400        1) its important to initially zero the entire field including
1401           the "halo" region
1402        2) zeroing needs to be done *before* reading pickup info
1403           and the pickup call might or might not happen in any
1404           particular run
1405      - this needs an overhaul for R2
1406    o cleanup verification/*/code/GMREDI_OPTIONS.h
1407    o cleanup testreport
1408    
1409    checkpoint51o_post

1414      - (front_relax/ )
1415    o (more) consistent directory structure for AD-related verif.'s
1416    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1417    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1418    o bug fix in find_alpha.F for MDJWF:
1419      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1420        change rho -> rho-rhoConst
1421      - replace call find_rho to find_rhonum
1422    o initialisation of rFlx extended to full array (required by TAF)
1423      and shifted to thermodynamics
1424    o removed PTRACERS.h in ptracers routine
1425    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1426    o Correcting initialisations for fVerU, fVerV.

1430    checkpoint51o_pre
1431    
1432    o undid all of cp51 pending some cleanups and discussion
1433    o added the [#include "AD_CONFIG.h"] statement to all files that need
1434       it for adjoint/tl #defines
1435     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1436     o removed tools/genmake since it no longer works
1437    
1438    checkpoint51n_post
1439    o modifications to make FREEZE flux visible to pkg/kpp
1440      - moved surfaceTendencyTice from pkg/seaice to main code
1441      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1442      - subroutine FREEZE now limits only surface temperature
1443        (this means new output.txt for global_ocean.90x40x15,
1444         global_ocean.cs32x15, and global_with_exf)
1445    o added surface flux output variables to TIMEAVE_STATVARS
1446    
1447    checkpoint51n_pre
1448    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
1449    o added [#include "AD_CONFIG.h"] to all files that use the following
1450      defines:
1451      - ALLOW_ADJOINT_RUN
1452      - ALLOW_TANGENTLINEAR_RUN
1453      - ALLOW_ECCO_OPTIMIZATION
1454    
1455    checkpoint51m_post
1456    o incorporating changes to get TAMC/TAF working in genmake2
1457      - added new TAMC/TAF targets to the Makefile
1458      - various cleanups related to package handling
1459      - these changes should have no impact on the forward model
1460    
1461    checkpoint51l_post
1462    o changes to pkg/cal and pkg/exf that allow and speed-up long integrations
1463     - faster algorithm for cal_addtime.F

1466       model integration time
1467    
1468    checkpoint51l_pre
1469    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
1470    o enable to apply restoring on S & T only in a latitude band.
1471    o update output (external_forcing_surf modif. change truncation errors)
1472       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
1473    
1474  checkpoint51k_post  checkpoint51k_post
1475  o change default to: useNHMTerms=.FALSE.  o change default to: useNHMTerms=.FALSE.
1476   - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):   - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
