7    checkpoint58b_post
8    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
9      update output.txt of exp. aim.5l_cs.thSI
10    o various mnc cleanups and improvements:
11      + shrink lookup tables by factor of ~4
12      + better error reporting when running out of lookup space
13      + able to handle longer path/file names (up to 500 chars)
14    o adjoint:
15      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
16      - TBD: "hidden" mom_vecinv recomp. in dynamics
17    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
18     (allow to differentiate between forcing components using new integer flags:
19      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
20     and add new flag to put Dissipation tendency out of Adams-Bashforth.
21    o ecco
22      - enable trend removal from SSH anomaly obs.
23    o adjoint
24      - a fix for PmEpR when #undef EXACT_CONSERV
25      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
26      - try to fix "hidden" recomp. in forward_step for NLFS
27        (NLFS seems broken sometimes after I checked it in)
28    o seaice:
29     - add c-grid version of the dynamic solver:
30       + three new routines that are the c-grid substitute lsr, dynsolver
31         and ostres
32       + put a few fields that were local to dynsolver into global common
33         blocks, so that I can move the computation of stresses etc into
34         seaice_lsr (saves coding but may break the adjoint).
35     - replace more hardwired parameters by runtime parameters
36     - add ice masks that mask the rhs of the implicit solvers where there
37       is no ice (commented out in seaice_dynsolver, because i am not sure
38       if this works properly), eventually this should replace the clipping
39       of ice velocities in seaice_dynsolver to +/-40cm/s.
40    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
41      include it only where its needed
42    o move balancing of fluxes before the call of external_forcing_surf
43    o seaice:
44      - correct units of turning angles (now they are really in degrees)
45      - move computation of GWATX/Y out of main routine into dynsolver
46      - initialize GWATX/Y in seaice_init
47    o Apply mask on Fresh-Water flux (needed for SSH forcing).
48      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
49    o seaice: add runtime flags for turning angles (default to zero)
50    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
51      and trend from exf forcing and ctrl control adjustments
52    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
53      (since checkpoint57x_post)
54    o change the default rotation period to 86164.s = the Earth rotation
55    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
56      and based on a reference stratification. Tested within hs94.cs-32x32x5.
57    o seaice advection: add code for choosing between the default (2nd order
58      central differences) and multiDim advection schemes provided by
59      pkg/generic_advdiff
60    o seaice:
61      - removed all references to SEAICE_GRID.h fields from
62        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
63        (cubed-sphere configuration will change a little)
64      - grid computations in seaice_init are obsolete now.
65      - cleaned up code a little so that is easier to read (hopefully).
66      - added new (better?) discretizations of default advection and diffusion
67        (turn on with SEAICEuseFluxForm)
68      - replace 1 in 3d global fields by kSurface in growth.F
69      
70    checkpoint58a_post
71    o seaice:
72      - bug fix in advect.F
73    o shelfice:
74      - separate shelfice load anomaly from pload (breaks with time
75        dependent forcing), => introduce constant field shelficeLoadAnomaly.
76        Its default is 0., but it may be computed more cleverly from (unknown)
77        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
78        done offline. A good approximation of the pressure load anomaly is
79        necessary to avoid large initial adjustment processes underneath
80        deep-reaching shelfice.
81      - small fix in ISOMIP shelfice_thermodynamics
82      - add more sophisticated thermodynamics of Hellmer (1989), this is
83        now the default
84      - give a few constants more intuitive names
85    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
86      if bulk formulae are used in long integration (especially EmPmR). Turn
87      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
88      if balancePrintMean, the imbalance that is substracted is printed to
89      STDOUT.
90    o fix bug (typo) in obcs_apply_eta.F
91    o add a new package shelfice which enables us to model the circulation
92      underneath shelf-ice with draughts of hundreds of meters.
93     - works
94     - to do: + include improved thermodynamics
95              + check whether kSurfC (from model/inc/SURFACE.h) can be used
96                instead of new field kTopC
97              + can we use topoFile, Ro_surf and existing code in ini_depth.F
98                instead of new field R_shelfIce and new code in ini_depth.F
99                and ini_mask_etc.F?
100              + adjust vertical mixing schemes?
101    o seaice pkg:
102     - add a cpp-flag to include a simple formula for a salinity dependent
103       freezing point of sea water at the surface
104     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
105       meridional stresses are now different (and hopefully correct)
106    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
107       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
108       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
109    o pkg/diagnostics: add options and parameters for regional-statistics
110       diagnostics ; define regions by reading a region-mask from a file
111       (might add other options later)
112    o pkg/bulk_force:
113     - add option and parameters to use AIM surface-flux formulae.
114     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
115       others forcing fields (defined in PARM05, parameter file "data") are loaded
116       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
117     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
118     - use the right EXCH call for uwind,vwind (to work on CS-grid).
119     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
120       and parameters (note: calcWindStress replaces .NOT.readwindstress).
121     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
122    
123    checkpoint58
124    o add "--embed-source" option to genmake2 which, when the supporting
125      tools can be compiled (as determined by genmake2) will turn on the
126      embed_files package which then embeds the entire MITgcm source code
127      (*.[fFhc] + Makefile) used for the build within the executable
128      - requested by CNH but off by default
129      - adds a paltry <9MB to the mitgcmuv executable in most cases
130      - only writes the output when useEMBEDSRC in eedata is true
131    o clean up 3-dim. relaxation codes:
132      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
133      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
134      * Thanks to Tom Haine for testing!
135    
136    checkpoint57z_post
137    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
138      affects output (@ truncation level) of exp. plume_on_slope ; updated.
139    o fix the pickup behavior for obcs in combination with ptracers
140    o fix a bug in ptracers_external_fields_load
141    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
142      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
143    o transfered surface NH pressure to eta field (if exactConserv).
144    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
145         and update lab_sea output.txt file.
146    o completing 3-dim. relaxation code: additional term
147         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
148      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
149      * At compile time, in "EXF_OPTIONS.h" set
150          #define  ALLOW_CLIMTEMP_RELAXATION
151          #define  ALLOW_CLIMSALT_RELAXATION
152      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
153          tauThetaClimRelax3Dim = 15552000.0,
154          tauSaltClimRelax3Dim  = 15552000.0,
155      * 3 cases:
156          1) Use a constant-in-time 3-dim. field
157          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
158          3) Real-time relax. to time-evolving prescribed field
159    o Adding Laplacian-type smoothness constraint on
160      initial and boundary (forcing) controls (ic, bc)
161      * enable at compile-time via
162        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
163      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
164      * Absolute scale somewhat unclear so far
165      * no area weighting was included since no other cost term does so far
166    
167    checkpoint57y_post
168    First step for a NLFS adjoint
169    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
170    o new init. routines for calc_r_star, calc_surf_dr
171    o still need to deal with ini_masks_etc
172    o testreport seemed happy
173    checkpoint57y_pre
174    
175    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
176    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
177    o add new offset feature to offline pkg (plus minor cleanup)
178    o cfc fixes for final year of integration
179    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
180      be in GCHEM_OPTIONS).
181    
182    checkpoint57x_post
183    o fix testreport Pb in multiple test experiment.
184    o cleanup our namelist syntax in verification:
185      - make it more F95 standards compliant (some work still needed)
186      - allows the vast majority of our tests to work with gfortran
187    o Non-Hydrostatic:
188     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
189     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
190    o Allow to apply AB on T,S rather than on AB(gT,gS):
191     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
192     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
193       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
194     - need a "clever" read_pickup to restart from the other AB formulation
195    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
196    o remove some unused variables (reduces number of compiler warnings)
197    o adjoint
198      * Disable useVariableViscosity for adjoint for time being
199        (there are a number of extensive recomputations)
200      * Initialize certain variables needed for adjoint
201    
202    checkpoint57w_post
203    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
204                 fix the singleCpuIO RS version of MDSWRITEFIELD
205       and add a WARNING if using globalFiles=T with multi-processors.
206    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
207      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
208    o tracer advection scheme:
209      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
210       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
211       was not very convenient).
212      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
213       (further tests needed for the implicit DST & Flux-Limiter schemes).
214    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
215      and sRef for convenience, handy, when you want to initialize
216      ptracers in a large domain with a constant non-zero value. Also,
217      untangle ptracers_init.F a little.
218    
219    checkpoint57v_post
220    o change dome exp. to use variable viscosity in side-drag terms.
221    o remove all the files from the cfc_offline test since they are now
222      incorporated into tutorial_cfc_offline which has been producing
223      identical results for a few days of testing
224    o add new parameter: sideDragFactor to enable half-slip-side BC
225      and change side-drag S/R to use viscosity from mom_calc_visc
226      (can switch back by setting sideDragFactor=0.); affects results at
227      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
228       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
229    o vorticity & strain are now computed without masking, to account for
230      no-slip-side BC in variable viscosity calculation ; mask is applied
231      anyway later on, before computing advection/coriolis terms.
232    o modify exp4 to test new obcs support for reading from external files
233      and for passive tracers
234    o fix behavior of ptracers_monitor when monitor output is written to a
235      netcdf-file; still not independent of monitor.F (writes in the same
236      file).
237    o change default value of tRef (put a uniform, meaningful value for ocean
238      & atmos) and initialize sRef (was missing, as Martin mentioned).
239    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
240      to be proportional to enstrophy dissipation length.  Thus,
241       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
242      This is now consistent with Smagorinsky and with the manual.
243    
244    checkpoint57u_post
245    o OBCS and PTRACERS: add open boundary support for passive tracers
246      - either use homogenous (pseudo) v.Neumann conditions or prescribe
247        OB-values from file; this is not different from the way theta and salinity
248        are treated
249      - however, Orlanski-radiation conditions are not supported, and the model
250        will stop if you use pTracers and Orlanski at the same time.
251      - beefed up the rountine obcs_external_fields_load: now only those open
252        boundary values are overwritten with values from files for which there
253        are really files, otherwise the OB-fields remain untouched. This makes
254        it possible to use different OBs at different ends of the domain (as
255        with EXF)
256    o reduce number of exch calls in shap_filt (s2).
257    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
258      truncation level) 4/5 MLAdjust test results (11&12 digits match).
259    
260    checkpoint57t_post
261    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
262    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
263      same truncation, independent of the face number: affects affects several
264      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
265    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
266      note that biharmonic viscosity + no-slip was not tested in any experiment.
267    o fix bug in non-linear free-surf side-drag ; generate new output for
268      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
269    o make mnc honor the writeBinaryPrec flag for most kinds of output
270    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
271    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
272      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
273    o add brackets in multi-terms sum to get same truncation, independent of
274      the face number (manage to get exactly same value of gU,gV at the cs-edge)
275      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
276    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
277      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
278      a maximum grid-scale Reynolds number.  Also, changes all length calculations
279      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
280      Suggested values of viscosity parameters found in mom_calc_visc.
281      Many new viscosity diagnostics available.
282    
283    checkpoint57s_post
284    o Add clearing-house for viscosity calculations, mom_calc_visc and
285      correct numerous bugs in LeithD and Smagorinsky discretizations.  
286      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
287      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
288      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
289      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
290      The Strain-Tension form is now called with useStrainTensonVisc=.true.
291      ViscAhStrain and viscAhTension are now retired.
292    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
293    o In response to JMC's bug report, genmake2 now ignores any soft-links
294      that it finds in the *current* directory when searching for files.
295      Soft-links found in any other source directories will still work as
296      they did before.
297    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
298      a C routine to unlimit the stack size
299    o mnc-ify pkg/aim snapshot vars
300    o mnc-ify pkg/land as requested by Daniel
301    o various changes to mnc including:
302      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
303      - output can now be grouped so that all files within a group
304          change the ITER portion of their names in lock-step together
305      - can now read ("global") PER-FACE (in addition to PER-TILE) files
306          and works with both EXCH1 and EXCH2 (but needs more testing)
307      - writing works for all verification test cases w/ g77 on Linux
308    
309    checkpoint57r_post
310    o make MNC variable initialization happen earlier
311    o add diagnostics for (almost) each term of the momentum Eq.
312    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
313    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
314    o remove MINIMAL_TAVE_OUTPUT option ;
315      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
316    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
317      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
318    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
319    o add time-dependent SST, SSS control
320    o cost terms in ecco/ modularized (new cost_generic.F)
321    o cost_averages routines are modularized (new cost_averagesgeneric.F)
322    o new infrastructure for seaice model vs. obs misfits in seaice/
323      * driver from the_main_loop.F is seaice_cost_driver.F
324      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
325      * gradient check in Exp. 6a of natl_box_adjoint/
326    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
327      (see README file)
328    
329    checkpoint57q_post
330    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
331    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
332      - bug was reported by Jean-Michel and Ian Fenty
333    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
334      update exp. cpl_aim+ocn output.
335    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
336      Needed for high-res. runs with large global files
337      to be able to limit tapelev size
338    o Changed some tests for adjoint:
339      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
340      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
341      * global_ocean.90x40x15/ back to default 3-level checkpointing
342    o Modifications to enable scripted COMMON to MODULE conversion
343      * verification/OpenAD/code/ has necessary scripts and description;
344      * converts, compiles and runs successfully;
345    
346    checkpoint57p_post
347    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
348    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
349      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
350    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
351    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
352      (was already the case for dissipation with mom_vecinv,
353       and also the case for grad.PhiHyd when staggered-timeStep)
354      This will allow to put dissipation out-off the AB time-stepping.
355     Unfortunately, affects truncation error. Update output of exp. that "fails"
356      (cg2d matching number) and leave the others for later: front_relax(10),
357      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
358      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).

361    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
362      (2) its ready to be documented during the 20050801 DocFest
363    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
364      for ideal_2D_oce and lab_sea on linux_ia32_g77
365    o set to #undef CTRL_SET_OLD_MAXCVARS_30
366      in global1x1_tot/code_seaice_adj to access indices 32, 33
367      (worth another tag)
368    
369    checkpoint57n_post
370    o adding precip control xx_precip 32
371    o adding swflux control xx_swflux 33
372    o Replacing 10 forcing penalty cost routines by 1 generic.
373    o Implementing partitioning in time-mean and variable adjustment
374      for atmos. state.
375    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
376    o in natl_box_adjoint:
377      * updated exp 1 to 10
378        (but does not have time-mean vs. variable split results yet)
379    o updated global1x1/*_seaice_adj/
380      to incorporate latest changes
381    o enable useSingleCpuIO for mdsio vector routines
382      (applies in particular to tapelev I/O)
383    o removed inefficient K-loop in all active_file*control*.F
384    
385    checkpoint57m_post
386    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
387      and advect_cs (use EXCH-2 and standard cs-32 grid files).
388    o pkg/exch2: filling of face-corner halo regions is optional
389      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
390    
391    checkpoint57l_post
392     tag before updating tutorials (pre-release-2)
393    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
394       for output and interpolation of input fields onto model grid)
395    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
396       Affects results of exp. rotating_tank ; update output.txt.
397    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
398          and taking the square quantity and/or using a fraction-weight field.
399    o fix aim_diagnostics_init.F mate numbers.
400    o add mnc output capability to diagnostics/diagstat and update
401      our cvsignore files for the ACSII output generated
402    
403    checkpoint57k_post
404    o lab_sea now uses diagnostics package and provides a suite of
405      new EXF diagnostics output.
406    
407    checkpoint57j_post
408    o exf
409      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
410        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
411        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
412      * extended diagnostics output
413        - now includes all EXF variables
414        - hs, hl moved to common block
415        - separate S/R for diagnostics, called after ctrl vector is added
416        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
417        - EXFqnet contains true Qnet (i.e. includes qsw)
418      * updated verif. lab_sea, global_with_exf
419      * Rearranging hflux (exf_mapfields -> exf_getforcing)
420        to ensure that diagnostics sees a true EXFqnet
421    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
422    o diagnostics pkg: change pointers so that 1 diagnostic can be used
423      several times with different frequencies.
424    o mnc-ify the thsice package as requested by Daniel Enderton
425      - the monitor--MNC output needs work
426      - many attributes need to be added (most are currently blank)
427    o mnc-ify theaim_v23 package as requested by Daniel Enderton
428      - many attributes need to be added (most are currently blank)
429    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
430    o add Sadourny like discretization to the 4th.O vorticity advection scheme
431    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
432      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
433         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
434    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
435     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
436    
437    checkpoint57i_post
438    o Diagnostics package was changed: diagnostic allocation is now deactivated
439      by setting an empty file name in the namelist (used to be by setting 0 frequency)
440    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
441      add 1rst Order upwind vertical Shear.
442    o add a quick fix for A/B checkpointing in OFFLINE mode
443    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
444      end-run around the C/Fortran linking horror in eesup/src/timers.F
445    o added pkg/runclock: allows user to terminate run based on wall clock
446    o added non-hydrostatic scaling parameter: nh_am2
447    o pkg/my82: futile attempt to make results compiler-independent by adding
448      some "_d 0", etc. no effect.
449    o for mnc output, fill the 'T' coordinate var with myTime and create a
450      separate 'iter' variable for iteration count
451    o pkg/diagnostics:
452      add new capability: output of Global/Regional & per-level statistics ;
453      tested against monitor output (including land & thSIce) on various exp.
454    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
455    
456    checkpoint57h_done
457      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
458      data.diagnostics, data.gchem, data.ptracers) is done.
459    
460    o pkg/diagnostics: prepare for Global/Regional statistics.
461      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
462    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
463      and rename it: DIFFERENT_MULTIPLE
464    
465    checkpoint57h_post
466    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
467    o pkg/diagnostics: change output frequency, now in seconds (instead
468      of Nb of iterations). This requires to change data.diagnostics.
469    checkpoint57h_pre
470    
471    o in mnc, let the user create the output dir if both mnc_outdir_date
472      and mnc_outdir_num are false
473    o add fflags() to pkg/diagnostics which allows one to specify, on a
474      per-file basis, the file precision [default behavior is unchanged]
475    o added diagnostics to pkg/kpp, including computation of mixed layer
476      depth based on a temperature/density criterion
477    o updated verification/natl_box to test the new pkg/kpp diagnostics
478    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
479    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
480    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
481      not mnc -- this mistake was found by JMC and is now corrected
482    
483    checkpoint57g_post
484    o add Adams-Bashforth 3rd Order time stepping:
485      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
486      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
487    checkpoint57g_pre
488    
489    o make lambda[Theta,Salt]ClimRelax spatially varying
490      (default remains spatially uniform constant based on tau)
491    o added new control variables
492      * init. uVel, vVel, etanN
493      * lambda[Theta,Salt]ClimRelax
494    o separate masks used for ctrl_pack/unpack 'from write_grid' output
495      (suggested by G. Forget)
496    
497    checkpoint57f_post
498    o add parameter "baseTime" = model base time = time at iteration zero
499      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
500      account for baseTime shift
501    o move Coriolis arrays from PARAMS.h to GRID.h
502    checkpoint57f_pre
503    
504    o mnc-ifying the seaice package
505    o introduced an alternative length scale calculation for use in the limiting
506      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
507    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
508    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
509      as well as grad(vort3).  Made it compatible with both approximate form
510      for the cubed sphere and full form of these gradients.  Added flag
511      useFullLeith to select between approximate and full form.  
512    o add "d0" in getcon.F to reduce differences between compilers/platforms
513      update output.txt of exp. fizhi-gridalt-hs
514    o change port_rand funtion to allow to set the seed.
515    o fix obscure MNC bug involving conversion between reals and integers
516      - it caused no problems with certain (eg. gcc, ifc) compilers but the
517        new version is now more standards-compliant
518    o adjoint-related modifications
519      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
520      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
521      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
522    
523    checkpoint57e_post
524    o Adding eddy stress controls a la Ferreira et al.
525    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
526    
527    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
528      update output.txt of exp. fizhi-gridalt-hs
529    o add more "Z" dimensions and associated coordinate vars to MNC
530    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
531    o parameter calendarDumps: when set, approximate months (30-31 days) and years
532      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
533      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
534      months and years.  Requires pkg/cal.
535    o diagnostics: add pickup functionality
536      - off by default for backwards compatibility
537      - current version only uses MDSIO -- MNC will be added
538    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
539    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
540    
541    checkpoint57d_post
542    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
543    o modify verification/ideal_2D_oce so that it tests the creation of mnc
544      output from the diagnostics package
545    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
546    o make genmake2 more portable by using ".$FS" instead of ".f" for more
547      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
548    o add coordinate variables to the MNC output from the diagnostics package
549    o change MNC-flags default value: true when useMNC=TRUE
550    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
551      the ability (off by default) to read the grid information using MNC
552    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
553    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
554    o do snap-shot diagnostics at the middle of the time-interval (instead of
555      at the end).
556    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
557      new test for AIM with thSIce + slab-ocean
558    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
559    o move state variable diagnostics to the beginning of the time step ;
560      (note: still needs some work specially for snap-shot diagnostics)
561      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
562    
563    checkpoint57c_post
564    o Change testing option (-ieee) to get closer agreement between g77 & ifort
565    o generate new output.txt files on faulks with g77 & the new -ieee option
566    checkpoint57c_pre
567    
568    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
569      update output.txt of exp. global_ocean.90x40x15
570    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
571      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
572    o add saltFlux(+File) forcing capability with periodicExternalForcing
573    o allow to use pkg diagnostics for GM-Redi & ThSIce output
574    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
575    o improvements for the MNC output from DIAGNOSTICS:
576      - correct handling of the unlimitied dimension
577      - all dims now have associated coordinate variables
578      - variables located at U, V, and Corner ("Z") points are now written
579        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
580        *all* data points are output
581    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
582    o added pkg/seaice/seaice_monitor.F
583    o mdsio_readfield.F can now read files visible only to master MPI process.
584    o pkg/seaice: some test code for ice-modified ocean stress
585    o exf_getffields interpolation defaults to bilinear for all scalar forcing
586      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
587      spurious negative numbers for precipitation and humidity.  Will cause
588      some small numerical differences for integrations using pkg/exf/exf_interp.F.
589    o pkg/ctrl/
590      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
591        May be enabled via doPackDiag
592      *  introduce z-scaling of
593         + gradient (doZscalePack) and
594         + control (doZscaleUnpack)
595    o pkg/mdsio/
596      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
597      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
598    
599    checkpoint57b_post
600    o simplify options in diagnostics_fill arguments (remove weird combinations)
601    o fix MNC coordinate variables so that they now contain per-face index
602      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
603      general, EXCH2 grids are only aligned to a "local" coordinate system
604    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
605    o Implement instantaneous output within pkg diagnostics:
606      setting a negative frequency in data.diagnostics produces
607     "snap-shot" output (as opposed to time-average if freq > 0)
608    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
609      NOTE: change ptracer diagnostics name: use 2 characters to work with
610            more than 9 tracers. Add also diagnostics of advect & diffus flux.
611    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
612      becomes the coordinate variable for the 'T' dimension
613    o add CF-style coordinate variables to MNC
614      - just a first cut:  numbers are meaningless on the cubesphere and
615        missing along the T axis but otherwise it works!
616    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
617    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
618    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
619      this is based directly on what the model compute, so that the content of
620      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
621    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
622    o clean up build options files for SunOS, in particular
623      - remove -traditional from xmakedepend
624      - change -xarch=v9 to -xarch=native for f77
625      - restore use of make (not gmake)
626      - add CC=gcc if using g77
627    o changes per discussion of AM, JMC, & EH3 today:
628      - move redundant "grid" variables out of "state" -- in preparation of
629        creating proper CF-style coordinate variables and in recognition
630        that any/all grid variables can be easily copied (eg. w/NCO) from
631        the grid files into any of the other NetCDF files
632      - *always* output grid variables with MDSIO (this will eventually be
633        changed)
634      - output MNC grid file if useMNC is true
635    o every instance of _END_MASTER() has been found and replaced with
636      _END_MASTER( myThid ) in order to satisfy certain picky Sun
637      preprocessors
638    o re-arrange diagnostics pkg initialisation:
639     - allow each package to extend the available diagnostics list
640     - add some checking and fix small problems (multi-threaded, ...)
641     - new S/R diagnostics_fill (replace fill_diagnostics):
642       look through the short list of active diag. (instead of the long list)
643       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
644    
645    checkpoint57a_post
646    o this set of changes restores TAMC compatibility
647      tested for global_ocean.90x40x15 adjoint on trough
648      (what a pain)
649    
650    checkpoint57a_pre
651    o some modifs in tools/build_options for sunos
652    o call ctrl_pack for ctrl at end for optimcycle=0
653    
654    checkpoint57
655    o add horizontal bi-harmonic viscosity for vertical velocity
656      - new parameter viscA4W (defaults to viscA4)
657      - affects only non-hydrostatic code
658      - to be done: no-slip lateral boundary conditions
659    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
660    o implement Implicit Vertical advection for pTracers
661    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
662      (implemented also for implicit vertical diffusion & advection)
663    o OBCS: extend application of tracer open boundary conditions
664      to a strip beyond the boundary of width Olx/Oly
665    o add call monitor to TAF set of required calls (flow directives)
666      and include in natl_box_adjoint
667    o untangle a few ifdefs related to cost, ctrl, autodiff
668      untangel a few ALLOW_ECCO_OPTIMIZATION
669    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
670      (theta2, salt2 in ecco_cost_weights)
671    
672    checkpoint56c_post
673    o OBCS as control variables
674      - update ctrl_ad_diff.list, obcs_ad_diff.list
675      - remove balance of obcs controls from default
676      - fix index bug nobcs in ctrl_init
677      - fix dummy fields filen in ctrl_pack
678      - add dummy weights for obcs
679    o lsopt: comment out fort.94 output
680    o optim:
681      - remove unnecessary header files
682      - adjusted namelists
683      - add xerbla.F to Makefile
684    o exf:
685      - multiple modifications of exf_check_range
686      - unit change in exf_init_runoff from [m/year] to [m/s]
687    o mdsio:
688      - i/o-vector change debugLevel from debLevA to debLevB
689    
690    checkpoint56b_post
691    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
692      is called from DO_THE_MODEL_IO
693      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
694      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
695      - clean up PTRACERS_WRITE_TIMEAVE a little
696    o add another verification experiment that tests both the cfc-pkg and
697      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
698      reactive tendencies treated inline with regular timestepping
699    o testreport previously did a lousy job of comparing small numbers, so
700      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
701      implemented in the little c-progam tmp_cmpnum.c which is embedded in
702      testreport.
703    o ptracers_monitor: bug fix for MPI
704    
705    checkpoint56a_post
706    o GCHEM: finish reorganizating the package
707      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
708        (introduces another 3D-array for each passive tracer, but only if
709        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
710        gchemTendency is not needed because the timestep is done separately)
711      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
712      - GCHEM is now---more or less cleanly---separate from PTRACERS
713      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
714        so clear to me how that should be done in a general way.
715    o CFC: improve formatting of output in CFC_ATMOS
716    o PTRACERS:
717      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
718        that ALL experiments with ptracers enable can be checked. This makes
719        GCHEM_MONITOR obsolete.
720      - include a runtime parameter PTRACERS_monitorFreq that defaults to
721        monitorFreq
722      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
723    o add PTRACERS (PTR0[1-5]) to testreport output
724    o exf_check_range:
725      * default changed to .TRUE.
726      * will check values for niter0 if debLevA, every timestep if debLevB
727      * STOP in exf_check_range if 'out of range'
728      * range chosen generous to allow for potential extema
729      TBD: a version with stricter range
730           permitted range would be runtime parameters
731  o GMredi:  o GMredi:
732    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;

739      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
740        this flag is now only visible within GCHEM-pkg routines.
741      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
742        be replaced by a 3D array that is computed before thermodynamics; for
743        this, the tracer ID iTracer had to be included into the parameter list
744        of ptracers_forcing
745      - set up forward_step to call gchem_forcing, that will replace
746        gchem_forcing_int in ptracers_forcing
