5      ==============================      ==============================
6    
7    o move calendarDumps from "data" to "data.cal" and clean-up the code
8      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
9    o add useEXF & useCAL flags (for now, set in hard-coded way)
10    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
11      (were missing in NH mode, and wrong in quasihydrostatic mode).
12      waiting for Chris updated version of calc_gw to add those CALLs.
13    o fix bug in quasihydrostatic S/R ;
14      add a test for this option: global_ocean.90x40x15.qshyd
15    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
16      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
17    o add on/off flag useOffLine for package OFFLINE
18    o seaice:
19      - modify advection so that it works also on the C-grid
20      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
21        problem in multi-tile runs with C-grid
22      - add flags for clipping ice velocities and/or masking solver forcing
23      - fix drag (ocean on ice) formulation and a bug that caused noise in the
24        C-grid solver
25      - added a few comments to seaice_diffusion.F
26      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
27        are now exclusive)
28      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
29        required re-ordering the code a little:
30       + make DAIRN global variable (defined in SEAICE)
31       + move computation of the viscosities eta and zeta into a new separate
32         routine (because I need to recompute them in seaice_ocean_stress.F)
33    
34    checkpoint58b_post
35    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
36      update output.txt of exp. aim.5l_cs.thSI
37    o various mnc cleanups and improvements:
38      + shrink lookup tables by factor of ~4
39      + better error reporting when running out of lookup space
40      + able to handle longer path/file names (up to 500 chars)
41    o adjoint:
42      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
43      - TBD: "hidden" mom_vecinv recomp. in dynamics
44    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
45     (allow to differentiate between forcing components using new integer flags:
46      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
47     and add new flag to put Dissipation tendency out of Adams-Bashforth.
48    o ecco
49      - enable trend removal from SSH anomaly obs.
50    o adjoint
51      - a fix for PmEpR when #undef EXACT_CONSERV
52      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
53      - try to fix "hidden" recomp. in forward_step for NLFS
54        (NLFS seems broken sometimes after I checked it in)
55    o seaice:
56     - add c-grid version of the dynamic solver:
57       + three new routines that are the c-grid substitute lsr, dynsolver
58         and ostres
59       + put a few fields that were local to dynsolver into global common
60         blocks, so that I can move the computation of stresses etc into
61         seaice_lsr (saves coding but may break the adjoint).
62     - replace more hardwired parameters by runtime parameters
63     - add ice masks that mask the rhs of the implicit solvers where there
64       is no ice (commented out in seaice_dynsolver, because i am not sure
65       if this works properly), eventually this should replace the clipping
66       of ice velocities in seaice_dynsolver to +/-40cm/s.
67    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
68      include it only where its needed
69    o move balancing of fluxes before the call of external_forcing_surf
70    o seaice:
71      - correct units of turning angles (now they are really in degrees)
72      - move computation of GWATX/Y out of main routine into dynsolver
73      - initialize GWATX/Y in seaice_init
74    o Apply mask on Fresh-Water flux (needed for SSH forcing).
75      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
76    o seaice: add runtime flags for turning angles (default to zero)
77    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
78      and trend from exf forcing and ctrl control adjustments
79    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
80      (since checkpoint57x_post)
81    o change the default rotation period to 86164.s = the Earth rotation
82    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
83      and based on a reference stratification. Tested within hs94.cs-32x32x5.
84    o seaice advection: add code for choosing between the default (2nd order
85      central differences) and multiDim advection schemes provided by
86      pkg/generic_advdiff
87    o seaice:
88      - removed all references to SEAICE_GRID.h fields from
89        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
90        (cubed-sphere configuration will change a little)
91      - grid computations in seaice_init are obsolete now.
92      - cleaned up code a little so that is easier to read (hopefully).
93      - added new (better?) discretizations of default advection and diffusion
94        (turn on with SEAICEuseFluxForm)
95      - replace 1 in 3d global fields by kSurface in growth.F
96      
97    checkpoint58a_post
98    o seaice:
99      - bug fix in advect.F
100    o shelfice:
101      - separate shelfice load anomaly from pload (breaks with time
102        dependent forcing), => introduce constant field shelficeLoadAnomaly.
103        Its default is 0., but it may be computed more cleverly from (unknown)
104        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
105        done offline. A good approximation of the pressure load anomaly is
106        necessary to avoid large initial adjustment processes underneath
107        deep-reaching shelfice.
108      - small fix in ISOMIP shelfice_thermodynamics
109      - add more sophisticated thermodynamics of Hellmer (1989), this is
110        now the default
111      - give a few constants more intuitive names
112    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
113      if bulk formulae are used in long integration (especially EmPmR). Turn
114      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
115      if balancePrintMean, the imbalance that is substracted is printed to
116      STDOUT.
117    o fix bug (typo) in obcs_apply_eta.F
118    o add a new package shelfice which enables us to model the circulation
119      underneath shelf-ice with draughts of hundreds of meters.
120     - works
121     - to do: + include improved thermodynamics
122              + check whether kSurfC (from model/inc/SURFACE.h) can be used
123                instead of new field kTopC
124              + can we use topoFile, Ro_surf and existing code in ini_depth.F
125                instead of new field R_shelfIce and new code in ini_depth.F
126                and ini_mask_etc.F?
127              + adjust vertical mixing schemes?
128    o seaice pkg:
129     - add a cpp-flag to include a simple formula for a salinity dependent
130       freezing point of sea water at the surface
131     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
132       meridional stresses are now different (and hopefully correct)
133    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
134       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
135       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
136    o pkg/diagnostics: add options and parameters for regional-statistics
137       diagnostics ; define regions by reading a region-mask from a file
138       (might add other options later)
139    o pkg/bulk_force:
140     - add option and parameters to use AIM surface-flux formulae.
141     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
142       others forcing fields (defined in PARM05, parameter file "data") are loaded
143       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
144     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
145     - use the right EXCH call for uwind,vwind (to work on CS-grid).
146     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
147       and parameters (note: calcWindStress replaces .NOT.readwindstress).
148     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
149    
150    checkpoint58
151    o add "--embed-source" option to genmake2 which, when the supporting
152      tools can be compiled (as determined by genmake2) will turn on the
153      embed_files package which then embeds the entire MITgcm source code
154      (*.[fFhc] + Makefile) used for the build within the executable
155      - requested by CNH but off by default
156      - adds a paltry <9MB to the mitgcmuv executable in most cases
157      - only writes the output when useEMBEDSRC in eedata is true
158    o clean up 3-dim. relaxation codes:
159      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
160      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
161      * Thanks to Tom Haine for testing!
162    
163    checkpoint57z_post
164    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
165      affects output (@ truncation level) of exp. plume_on_slope ; updated.
166    o fix the pickup behavior for obcs in combination with ptracers
167    o fix a bug in ptracers_external_fields_load
168    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
169      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
170    o transfered surface NH pressure to eta field (if exactConserv).
171    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
172         and update lab_sea output.txt file.
173    o completing 3-dim. relaxation code: additional term
174         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
175      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
176      * At compile time, in "EXF_OPTIONS.h" set
177          #define  ALLOW_CLIMTEMP_RELAXATION
178          #define  ALLOW_CLIMSALT_RELAXATION
179      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
180          tauThetaClimRelax3Dim = 15552000.0,
181          tauSaltClimRelax3Dim  = 15552000.0,
182      * 3 cases:
183          1) Use a constant-in-time 3-dim. field
184          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
185          3) Real-time relax. to time-evolving prescribed field
186    o Adding Laplacian-type smoothness constraint on
187      initial and boundary (forcing) controls (ic, bc)
188      * enable at compile-time via
189        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
190      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
191      * Absolute scale somewhat unclear so far
192      * no area weighting was included since no other cost term does so far
193    
194    checkpoint57y_post
195    First step for a NLFS adjoint
196    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
197    o new init. routines for calc_r_star, calc_surf_dr
198    o still need to deal with ini_masks_etc
199    o testreport seemed happy
200    checkpoint57y_pre
201    
202    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
203    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
204    o add new offset feature to offline pkg (plus minor cleanup)
205    o cfc fixes for final year of integration
206    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
207      be in GCHEM_OPTIONS).
208    
209    checkpoint57x_post
210    o fix testreport Pb in multiple test experiment.
211    o cleanup our namelist syntax in verification:
212      - make it more F95 standards compliant (some work still needed)
213      - allows the vast majority of our tests to work with gfortran
214    o Non-Hydrostatic:
215     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
216     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
217    o Allow to apply AB on T,S rather than on AB(gT,gS):
218     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
219     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
220       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
221     - need a "clever" read_pickup to restart from the other AB formulation
222    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
223    o remove some unused variables (reduces number of compiler warnings)
224    o adjoint
225      * Disable useVariableViscosity for adjoint for time being
226        (there are a number of extensive recomputations)
227      * Initialize certain variables needed for adjoint
228    
229    checkpoint57w_post
230    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
231                 fix the singleCpuIO RS version of MDSWRITEFIELD
232       and add a WARNING if using globalFiles=T with multi-processors.
233    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
234      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
235    o tracer advection scheme:
236      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
237       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
238       was not very convenient).
239      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
240       (further tests needed for the implicit DST & Flux-Limiter schemes).
241    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
242      and sRef for convenience, handy, when you want to initialize
243      ptracers in a large domain with a constant non-zero value. Also,
244      untangle ptracers_init.F a little.
245    
246    checkpoint57v_post
247    o change dome exp. to use variable viscosity in side-drag terms.
248    o remove all the files from the cfc_offline test since they are now
249      incorporated into tutorial_cfc_offline which has been producing
250      identical results for a few days of testing
251    o add new parameter: sideDragFactor to enable half-slip-side BC
252      and change side-drag S/R to use viscosity from mom_calc_visc
253      (can switch back by setting sideDragFactor=0.); affects results at
254      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
255       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
256    o vorticity & strain are now computed without masking, to account for
257      no-slip-side BC in variable viscosity calculation ; mask is applied
258      anyway later on, before computing advection/coriolis terms.
259    o modify exp4 to test new obcs support for reading from external files
260      and for passive tracers
261    o fix behavior of ptracers_monitor when monitor output is written to a
262      netcdf-file; still not independent of monitor.F (writes in the same
263      file).
264    o change default value of tRef (put a uniform, meaningful value for ocean
265      & atmos) and initialize sRef (was missing, as Martin mentioned).
266    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
267      to be proportional to enstrophy dissipation length.  Thus,
268       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
269      This is now consistent with Smagorinsky and with the manual.
270    
271    checkpoint57u_post
272    o OBCS and PTRACERS: add open boundary support for passive tracers
273      - either use homogenous (pseudo) v.Neumann conditions or prescribe
274        OB-values from file; this is not different from the way theta and salinity
275        are treated
276      - however, Orlanski-radiation conditions are not supported, and the model
277        will stop if you use pTracers and Orlanski at the same time.
278      - beefed up the rountine obcs_external_fields_load: now only those open
279        boundary values are overwritten with values from files for which there
280        are really files, otherwise the OB-fields remain untouched. This makes
281        it possible to use different OBs at different ends of the domain (as
282        with EXF)
283    o reduce number of exch calls in shap_filt (s2).
284    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
285      truncation level) 4/5 MLAdjust test results (11&12 digits match).
286    
287    checkpoint57t_post
288    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
289    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
290      same truncation, independent of the face number: affects affects several
291      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
292    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
293      note that biharmonic viscosity + no-slip was not tested in any experiment.
294    o fix bug in non-linear free-surf side-drag ; generate new output for
295      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
296    o make mnc honor the writeBinaryPrec flag for most kinds of output
297    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
298    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
299      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
300    o add brackets in multi-terms sum to get same truncation, independent of
301      the face number (manage to get exactly same value of gU,gV at the cs-edge)
302      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
303    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
304      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
305      a maximum grid-scale Reynolds number.  Also, changes all length calculations
306      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
307      Suggested values of viscosity parameters found in mom_calc_visc.
308      Many new viscosity diagnostics available.
309    
310    checkpoint57s_post
311    o Add clearing-house for viscosity calculations, mom_calc_visc and
312      correct numerous bugs in LeithD and Smagorinsky discretizations.  
313      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
314      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
315      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
316      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
317      The Strain-Tension form is now called with useStrainTensonVisc=.true.
318      ViscAhStrain and viscAhTension are now retired.
319    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
320    o In response to JMC's bug report, genmake2 now ignores any soft-links
321      that it finds in the *current* directory when searching for files.
322      Soft-links found in any other source directories will still work as
323      they did before.
324    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
325      a C routine to unlimit the stack size
326    o mnc-ify pkg/aim snapshot vars
327    o mnc-ify pkg/land as requested by Daniel
328    o various changes to mnc including:
329      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
330      - output can now be grouped so that all files within a group
331          change the ITER portion of their names in lock-step together
332      - can now read ("global") PER-FACE (in addition to PER-TILE) files
333          and works with both EXCH1 and EXCH2 (but needs more testing)
334      - writing works for all verification test cases w/ g77 on Linux
335    
336    checkpoint57r_post
337    o make MNC variable initialization happen earlier
338    o add diagnostics for (almost) each term of the momentum Eq.
339    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
340    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
341    o remove MINIMAL_TAVE_OUTPUT option ;
342      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
343    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
344      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
345    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
346    o add time-dependent SST, SSS control
347    o cost terms in ecco/ modularized (new cost_generic.F)
348    o cost_averages routines are modularized (new cost_averagesgeneric.F)
349    o new infrastructure for seaice model vs. obs misfits in seaice/
350      * driver from the_main_loop.F is seaice_cost_driver.F
351      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
352      * gradient check in Exp. 6a of natl_box_adjoint/
353    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
354      (see README file)
355    
356    checkpoint57q_post
357    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
358    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
359      - bug was reported by Jean-Michel and Ian Fenty
360    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
361      update exp. cpl_aim+ocn output.
362    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
363      Needed for high-res. runs with large global files
364      to be able to limit tapelev size
365    o Changed some tests for adjoint:
366      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
367      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
368      * global_ocean.90x40x15/ back to default 3-level checkpointing
369    o Modifications to enable scripted COMMON to MODULE conversion
370      * verification/OpenAD/code/ has necessary scripts and description;
371      * converts, compiles and runs successfully;
372    
373    checkpoint57p_post
374    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
375    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
376      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
377    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
378    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
379      (was already the case for dissipation with mom_vecinv,
380       and also the case for grad.PhiHyd when staggered-timeStep)
381      This will allow to put dissipation out-off the AB time-stepping.
382     Unfortunately, affects truncation error. Update output of exp. that "fails"
383      (cg2d matching number) and leave the others for later: front_relax(10),
384      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
385      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
386    
387    checkpoint57o_post
388    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
389      (2) its ready to be documented during the 20050801 DocFest
390    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
391      for ideal_2D_oce and lab_sea on linux_ia32_g77
392    o set to #undef CTRL_SET_OLD_MAXCVARS_30
393      in global1x1_tot/code_seaice_adj to access indices 32, 33
394      (worth another tag)
395    
396    checkpoint57n_post
397    o adding precip control xx_precip 32
398    o adding swflux control xx_swflux 33
399    o Replacing 10 forcing penalty cost routines by 1 generic.
400    o Implementing partitioning in time-mean and variable adjustment
401      for atmos. state.
402    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
403    o in natl_box_adjoint:
404      * updated exp 1 to 10
405        (but does not have time-mean vs. variable split results yet)
406    o updated global1x1/*_seaice_adj/
407      to incorporate latest changes
408    o enable useSingleCpuIO for mdsio vector routines
409      (applies in particular to tapelev I/O)
410    o removed inefficient K-loop in all active_file*control*.F
411    
412    checkpoint57m_post
413    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
414      and advect_cs (use EXCH-2 and standard cs-32 grid files).
415    o pkg/exch2: filling of face-corner halo regions is optional
416      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
417    
418    checkpoint57l_post
419     tag before updating tutorials (pre-release-2)
420    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
421       for output and interpolation of input fields onto model grid)
422    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
423       Affects results of exp. rotating_tank ; update output.txt.
424    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
425          and taking the square quantity and/or using a fraction-weight field.
426    o fix aim_diagnostics_init.F mate numbers.
427    o add mnc output capability to diagnostics/diagstat and update
428      our cvsignore files for the ACSII output generated
429    
430    checkpoint57k_post
431    o lab_sea now uses diagnostics package and provides a suite of
432      new EXF diagnostics output.
433    
434    checkpoint57j_post
435    o exf
436      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
437        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
438        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
439      * extended diagnostics output
440        - now includes all EXF variables
441        - hs, hl moved to common block
442        - separate S/R for diagnostics, called after ctrl vector is added
443        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
444        - EXFqnet contains true Qnet (i.e. includes qsw)
445      * updated verif. lab_sea, global_with_exf
446      * Rearranging hflux (exf_mapfields -> exf_getforcing)
447        to ensure that diagnostics sees a true EXFqnet
448    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
449    o diagnostics pkg: change pointers so that 1 diagnostic can be used
450      several times with different frequencies.
451    o mnc-ify the thsice package as requested by Daniel Enderton
452      - the monitor--MNC output needs work
453      - many attributes need to be added (most are currently blank)
454    o mnc-ify theaim_v23 package as requested by Daniel Enderton
455      - many attributes need to be added (most are currently blank)
456    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
457    o add Sadourny like discretization to the 4th.O vorticity advection scheme
458    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
459      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
460         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
461    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
462     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
463    
464    checkpoint57i_post
465    o Diagnostics package was changed: diagnostic allocation is now deactivated
466      by setting an empty file name in the namelist (used to be by setting 0 frequency)
467    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
468      add 1rst Order upwind vertical Shear.
469    o add a quick fix for A/B checkpointing in OFFLINE mode
470    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
471      end-run around the C/Fortran linking horror in eesup/src/timers.F
472    o added pkg/runclock: allows user to terminate run based on wall clock
473    o added non-hydrostatic scaling parameter: nh_am2
474    o pkg/my82: futile attempt to make results compiler-independent by adding
475      some "_d 0", etc. no effect.
476    o for mnc output, fill the 'T' coordinate var with myTime and create a
477      separate 'iter' variable for iteration count
478    o pkg/diagnostics:
479      add new capability: output of Global/Regional & per-level statistics ;
480      tested against monitor output (including land & thSIce) on various exp.
481    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
482    
483    checkpoint57h_done
484      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
485      data.diagnostics, data.gchem, data.ptracers) is done.
486    
487    o pkg/diagnostics: prepare for Global/Regional statistics.
488      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
489    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
490      and rename it: DIFFERENT_MULTIPLE
491    
492    checkpoint57h_post
493    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
494    o pkg/diagnostics: change output frequency, now in seconds (instead
495      of Nb of iterations). This requires to change data.diagnostics.
496    checkpoint57h_pre
497    
498    o in mnc, let the user create the output dir if both mnc_outdir_date
499      and mnc_outdir_num are false
500    o add fflags() to pkg/diagnostics which allows one to specify, on a
501      per-file basis, the file precision [default behavior is unchanged]
502    o added diagnostics to pkg/kpp, including computation of mixed layer
503      depth based on a temperature/density criterion
504    o updated verification/natl_box to test the new pkg/kpp diagnostics
505    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
506    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
507    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
508      not mnc -- this mistake was found by JMC and is now corrected
509    
510    checkpoint57g_post
511    o add Adams-Bashforth 3rd Order time stepping:
512      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
513      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
514    checkpoint57g_pre
515    
516    o make lambda[Theta,Salt]ClimRelax spatially varying
517      (default remains spatially uniform constant based on tau)
518    o added new control variables
519      * init. uVel, vVel, etanN
520      * lambda[Theta,Salt]ClimRelax
521    o separate masks used for ctrl_pack/unpack 'from write_grid' output
522      (suggested by G. Forget)
523    
524    checkpoint57f_post
525    o add parameter "baseTime" = model base time = time at iteration zero
526      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
527      account for baseTime shift
528    o move Coriolis arrays from PARAMS.h to GRID.h
529    checkpoint57f_pre
530    
531    o mnc-ifying the seaice package
532    o introduced an alternative length scale calculation for use in the limiting
533      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
534    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
535    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
536      as well as grad(vort3).  Made it compatible with both approximate form
537      for the cubed sphere and full form of these gradients.  Added flag
538      useFullLeith to select between approximate and full form.  
539    o add "d0" in getcon.F to reduce differences between compilers/platforms
540      update output.txt of exp. fizhi-gridalt-hs
541    o change port_rand funtion to allow to set the seed.
542    o fix obscure MNC bug involving conversion between reals and integers
543      - it caused no problems with certain (eg. gcc, ifc) compilers but the
544        new version is now more standards-compliant
545    o adjoint-related modifications
546      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
547      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
548      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
549    
550    checkpoint57e_post
551    o Adding eddy stress controls a la Ferreira et al.
552    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
553    
554    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
555      update output.txt of exp. fizhi-gridalt-hs
556    o add more "Z" dimensions and associated coordinate vars to MNC
557    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
558    o parameter calendarDumps: when set, approximate months (30-31 days) and years
559      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
560      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
561      months and years.  Requires pkg/cal.
562    o diagnostics: add pickup functionality
563      - off by default for backwards compatibility
564      - current version only uses MDSIO -- MNC will be added
565    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
566    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
567    
568    checkpoint57d_post
569    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
570    o modify verification/ideal_2D_oce so that it tests the creation of mnc
571      output from the diagnostics package
572    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
573    o make genmake2 more portable by using ".$FS" instead of ".f" for more
574      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
575    o add coordinate variables to the MNC output from the diagnostics package
576    o change MNC-flags default value: true when useMNC=TRUE
577    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
578      the ability (off by default) to read the grid information using MNC
579    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
580    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
581    o do snap-shot diagnostics at the middle of the time-interval (instead of
582      at the end).
583    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
584      new test for AIM with thSIce + slab-ocean
585    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
586    o move state variable diagnostics to the beginning of the time step ;
587      (note: still needs some work specially for snap-shot diagnostics)
588      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
589    
590    checkpoint57c_post
591    o Change testing option (-ieee) to get closer agreement between g77 & ifort
592    o generate new output.txt files on faulks with g77 & the new -ieee option
593    checkpoint57c_pre
594    
595    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
596      update output.txt of exp. global_ocean.90x40x15
597    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
598      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
599    o add saltFlux(+File) forcing capability with periodicExternalForcing
600    o allow to use pkg diagnostics for GM-Redi & ThSIce output
601    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
602    o improvements for the MNC output from DIAGNOSTICS:
603      - correct handling of the unlimitied dimension
604      - all dims now have associated coordinate variables
605      - variables located at U, V, and Corner ("Z") points are now written
606        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
607        *all* data points are output
608    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
609    o added pkg/seaice/seaice_monitor.F
610    o mdsio_readfield.F can now read files visible only to master MPI process.
611    o pkg/seaice: some test code for ice-modified ocean stress
612    o exf_getffields interpolation defaults to bilinear for all scalar forcing
613      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
614      spurious negative numbers for precipitation and humidity.  Will cause
615      some small numerical differences for integrations using pkg/exf/exf_interp.F.
616    o pkg/ctrl/
617      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
618        May be enabled via doPackDiag
619      *  introduce z-scaling of
620         + gradient (doZscalePack) and
621         + control (doZscaleUnpack)
622    o pkg/mdsio/
623      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
624      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
625    
626    checkpoint57b_post
627    o simplify options in diagnostics_fill arguments (remove weird combinations)
628    o fix MNC coordinate variables so that they now contain per-face index
629      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
630      general, EXCH2 grids are only aligned to a "local" coordinate system
631    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
632    o Implement instantaneous output within pkg diagnostics:
633      setting a negative frequency in data.diagnostics produces
634     "snap-shot" output (as opposed to time-average if freq > 0)
635    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
636      NOTE: change ptracer diagnostics name: use 2 characters to work with
637            more than 9 tracers. Add also diagnostics of advect & diffus flux.
638    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
639      becomes the coordinate variable for the 'T' dimension
640    o add CF-style coordinate variables to MNC
641      - just a first cut:  numbers are meaningless on the cubesphere and
642        missing along the T axis but otherwise it works!
643    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
644    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
645    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
646      this is based directly on what the model compute, so that the content of
647      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
648    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
649    o clean up build options files for SunOS, in particular
650      - remove -traditional from xmakedepend
651      - change -xarch=v9 to -xarch=native for f77
652      - restore use of make (not gmake)
653      - add CC=gcc if using g77
654    o changes per discussion of AM, JMC, & EH3 today:
655      - move redundant "grid" variables out of "state" -- in preparation of
656        creating proper CF-style coordinate variables and in recognition
657        that any/all grid variables can be easily copied (eg. w/NCO) from
658        the grid files into any of the other NetCDF files
659      - *always* output grid variables with MDSIO (this will eventually be
660        changed)
661      - output MNC grid file if useMNC is true
662    o every instance of _END_MASTER() has been found and replaced with
663      _END_MASTER( myThid ) in order to satisfy certain picky Sun
664      preprocessors
665    o re-arrange diagnostics pkg initialisation:
666     - allow each package to extend the available diagnostics list
667     - add some checking and fix small problems (multi-threaded, ...)
668     - new S/R diagnostics_fill (replace fill_diagnostics):
669       look through the short list of active diag. (instead of the long list)
670       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
671    
672    checkpoint57a_post
673    o this set of changes restores TAMC compatibility
674      tested for global_ocean.90x40x15 adjoint on trough
675      (what a pain)
676    
677    checkpoint57a_pre
678    o some modifs in tools/build_options for sunos
679    o call ctrl_pack for ctrl at end for optimcycle=0
680    
681    checkpoint57
682    o add horizontal bi-harmonic viscosity for vertical velocity
683      - new parameter viscA4W (defaults to viscA4)
684      - affects only non-hydrostatic code
685      - to be done: no-slip lateral boundary conditions
686    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
687    o implement Implicit Vertical advection for pTracers
688    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
689      (implemented also for implicit vertical diffusion & advection)
690    o OBCS: extend application of tracer open boundary conditions
691      to a strip beyond the boundary of width Olx/Oly
692    o add call monitor to TAF set of required calls (flow directives)
693      and include in natl_box_adjoint
694    o untangle a few ifdefs related to cost, ctrl, autodiff
695      untangel a few ALLOW_ECCO_OPTIMIZATION
696    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
697      (theta2, salt2 in ecco_cost_weights)
698    
699    checkpoint56c_post
700    o OBCS as control variables
701      - update ctrl_ad_diff.list, obcs_ad_diff.list
702      - remove balance of obcs controls from default
703      - fix index bug nobcs in ctrl_init
704      - fix dummy fields filen in ctrl_pack
705      - add dummy weights for obcs
706    o lsopt: comment out fort.94 output
707    o optim:
708      - remove unnecessary header files
709      - adjusted namelists
710      - add xerbla.F to Makefile
711    o exf:
712      - multiple modifications of exf_check_range
713      - unit change in exf_init_runoff from [m/year] to [m/s]
714    o mdsio:
715      - i/o-vector change debugLevel from debLevA to debLevB
716    
717    checkpoint56b_post
718    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
719      is called from DO_THE_MODEL_IO
720      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
721      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
722      - clean up PTRACERS_WRITE_TIMEAVE a little
723    o add another verification experiment that tests both the cfc-pkg and
724      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
725      reactive tendencies treated inline with regular timestepping
726    o testreport previously did a lousy job of comparing small numbers, so
727      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
728      implemented in the little c-progam tmp_cmpnum.c which is embedded in
729      testreport.
730    o ptracers_monitor: bug fix for MPI
731    
732    checkpoint56a_post
733    o GCHEM: finish reorganizating the package
734      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
735        (introduces another 3D-array for each passive tracer, but only if
736        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
737        gchemTendency is not needed because the timestep is done separately)
738      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
739      - GCHEM is now---more or less cleanly---separate from PTRACERS
740      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
741        so clear to me how that should be done in a general way.
742    o CFC: improve formatting of output in CFC_ATMOS
743    o PTRACERS:
744      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
745        that ALL experiments with ptracers enable can be checked. This makes
746        GCHEM_MONITOR obsolete.
747      - include a runtime parameter PTRACERS_monitorFreq that defaults to
748        monitorFreq
749      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
750    o add PTRACERS (PTR0[1-5]) to testreport output
751    o exf_check_range:
752      * default changed to .TRUE.
753      * will check values for niter0 if debLevA, every timestep if debLevB
754      * STOP in exf_check_range if 'out of range'
755      * range chosen generous to allow for potential extema
756      TBD: a version with stricter range
757           permitted range would be runtime parameters
758    o GMredi:
759      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
760      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
761      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
762    o GCHEM:
763      - move call to GCHEM_FORCING_SEP, so that it is now called before
764        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
765      - introduced a useGCHEM runtime flag and applied it everywhere.
766      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
767        this flag is now only visible within GCHEM-pkg routines.
768      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
769        be replaced by a 3D array that is computed before thermodynamics; for
770        this, the tracer ID iTracer had to be included into the parameter list
771        of ptracers_forcing
772      - set up forward_step to call gchem_forcing, that will replace
773        gchem_forcing_int in ptracers_forcing
774      - cleaning up
775    o small cleaning of exch2: remove files that are also in eesupp/src
776    
777    checkpoint56
778    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
779    o mnc: cleanup "full" files--fixes out-of-memory problem
780    o ECCO-GODAE
781      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
782      * fully merged and updated from SIO code
783        windstress sign change affects
784        - exf_inscal_[u/v]stress
785        - sign of xx_tau[u/v] adjustments
786        - signs in cost_scat
787      * ctrl_get_gen: avoid update of tau[u/v] for first few days
788      * natl_box_adjoint updated and compressed
789      * 2-level checkpoint switch added
790        (tested in EXP. 1 of natl_box_adjoint)
791      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
792    o SVD
793      * first complete, non-hacked version for SVD calculations
794      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
795        performed via direct access files admtlm_vector.it????
796        (via ctrl_[un]pack)
797      * optimcycle is used for ARPACK iteration counter
798        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
799      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
800        and add linear transforms where necessary
801      * controls are initial/final SST, SSS (can be extended; need to check
802        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
803    o mdsio: filename info to both stderr, stdout
804    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
805      from sign change
806    
807    checkpoint55j_post
808    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
809      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
810    o add consistent build directories and .cvsignore files to verification
811    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
812    o make all subroutines 30 or less characters in length for certain older
813      compilers to work (a thorough search only turns up two routines in
814      pkg/ptracers)
815    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
816      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
817    
818    checkpoint55i_post
819    o change arrays for total vertical diffusivity (2.D if explicit,
820      3.D if implicit) ; each ptracer uses its own background value.
821    o added mnc/NetCDF output capability to ocn_compon_interf
822      - added bits to verification/cpl_aim+ocn so that it can run on
823        ITRDA and other clusters without the mpirun "-wd" option
824    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
825      configuration
826    o give MNC the ability to create additional files rather than
827      exceeding a specified file size limit "MNC_MAX_FILESIZE"
828      - the default is just less than 2GB which is a practical limit
829        on many systems
830    o Compute the non-local term using either KPP vertical diffusivity (=default)
831       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
832    
833    checkpoint55h_post
834    o add verification test "vermix"
835    o remove all the *_ioinc flags and replace with the single global
836      outputTypesInclusive flag
837    o allow to set a vertical profile of vertical diffusivity for T & S
838    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
839    o useMNC moved from data.mnc to data.pkg
840    
841    checkpoint55g_post
842    o Renaming carbon AD experiments to comply with testreport conventions
843    o Updating adjoint of Held-Suarez hs94.1x64x5
844    o Fixing directives for non-ECCO forward_step, after ECCO directives
845      have been fixed to avoid recomp. of do_oceanic_phys
846      Works well for global_ocean.90x40x15,
847      but recomp. issue remains for carbon
848    o Updating adjoint output for natl_box_adjoint after
849      pkg/ecco has been modified (see taga c55d_post)
850    
851    checkpoint55f_post
852    o rename to timeave_init_fixed
853    
854    checkpoint55e_post
855    o some delicate re-shuffle of store directives to avoid one
856      extra call of do_oceanic_physics
857      affects ecco_the_main_loop.F, do_oceanic_physics.F
858      checkpoint_lev1_directives.h
859    o NB: this may break global_ocean adjoint temporarily,
860      but it is clear how to fix it. Will do later, need this now.
861    
862    checkpoint55d_post
863    o ECCO specific cost function terms (up-to-date with 1x1 runs)
864    o ecco_cost_weights is modified to 1x1 runs
865    o modifs to allow observations to be read in as
866      single file or yearly files
867    o enable to read exf forcing fields as either
868      single file or yearly files (flag useExfYearlyFields)
869    checkpoint55d_pre
870    
871    o switch between 2-level and 3-level checkpointing
872    o add ability of MNC to write local and "partial" (eg. 2D slices where
873      the full 3D field is never actually stored) arrays to NetCDF files
874      with the correct (that is, the complete multi-dimensional) set of
875      array indicies
876      - used in mom_vecinv() to write the diagFreq output
877      - tested (demonstrated) in verification/aim.5l_cs
878    o further mnc-ification
879      - add verification/lab_sea to the list with mnc setups
880      - fix undefined mnc v-names in cd_code
881      - add kpp to mnc output (both snapshot and timeave)
882    o non-hydrostatic code
883      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
884        in calc_gw.F
885      - defaults to viscAh
886      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
887        friction or Leith) in non-hydrostatic mode, as long as there is
888        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
889    o pkg/cost
890      extend simple cost functions to treat time mean quantities
891      (T,U,V) via cost_accumulate_state from cost_tile
892    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
893        be 2 times larger than the minimum size the advection scheme requires.
894        now get a perfect conservation of salt in advect_cs test-exp (updated)
895    o GGL90 (Gaspar's TKE mixed layer)
896      - add horizontal diffusion of TKE, requires exchanges in
897        do_fields_blocking_exchanges, horizontal diffusivity is zero by
898        default. In OPA there is no horizontal diffusion of TKE but the
899        mixing coefficients are computed from a horizontal average of TKE of
900        6 points or so. I think that diffusion has a little more physical
901        justification.
902      - clean up ggl90_calc in the hope of reducing memory usage (this hope
903        was in vain)
904      - mask tke-variable in ggl90_init
905    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
906    o fix biharmonic diffusion on CS-grid.
907    o more obcs stuff
908      - added obcs_external_fields_load as an alternative to the EXF-pkg option
909        for reading boundary values. This routine is called from
910        obcs_prescribe_read
911      - updated obcs_check
912      - changed sponge layer relaxation parameter units for days to seconds
913      - turned off sponge layer by default
914      - changed argument list of OBCS_CALC to myTime+deltaTclock
915      - fixed about 35 bugs in obcs_external_fields_load
916    
917    checkpoint55c_post
918    o obcs stuff
919      - new runtime flags useOBCSprescribe, useOBCSbalance
920      - re-arranged obcs_calc
921      - moved exf_getobcs to obcs_prescibe_read
922        obcs_prescibe_read is called after ORLANSKI stuff
923        and independent of it (executable can contain all).
924      - updated obcs_check
925      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
926        These may be necessary only if tangential velocities are
927        prescribed at OB, not sure, needs testing.
928    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
929      which simplifies the calls and passes the ifc check-bounds test
930    
931    checkpoint55b_post
932    o add a 2D scalar, Z location, exchange_2 routine.
933    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
934      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
935      affects advect_cs results (for the wrong reason): update output.txt
936    o use a more standard discretization for biharmonic viscosity ;
937     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
938      affects results of dome set-up: update output.txt
939    o fix gad_advection.F (CubedSphere part), back to version 1.23
940    o fix bug in mom_vi_del2uv.F (CubedSphere part).
941    
942    checkpoint55a_post
943    o merged code to
944      * prescribe/read time-dependent open boundaries
945        (works in conjunction with exf, cal)
946      * sponge layer code for open boundaries
947      * each boundary N/S/E/W now has its own CPP option
948        (healthy for the adjoint)
949    
950    checkpoint55
951    o up-to-date adjoint of previous breaks
952      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
953      - global_ocean_ebm: adjoint still needs fix (TLM ok)
954      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
955      - carbon: * remove tr1-related adjoint verification
956                * add ptracer as control variable
957    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
958      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
959    
960    checkpoint54f_post
961    o in verification/carbin/ remove experiment related to
962      ALLOW_PASSIVE_TRACER (array tr1 etc)
963      code_ad/ input_ad/ results_ad
964    
965    o add two new packages
966      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
967        + subject to optimization (memory)
968      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
969        + subject to reordering (many GOTOs in the original code)
970        + so far opps is called for every (i,j) point, and then operates in
971          the vertical; one may want to reorder the scheme in order operate in
972          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
973          fields)
974    o overhaul of IO so that we now have flags for MDSIO and/or MNC
975      - all verification tests compile and run with linux_ia32_g77
976      - defaults are compatible with current input files--nothing
977        should change if you were not previously using MNC
978      - MNC output has been added in numerous places (eg. timeave)
979        but there are still a few writes not yet do-able with MNC
980        (this is in progress)
981      - flags now allow for either/or/both use of MDSIO and MNC and
982        documentation will soon follow
983      - numerous small formatting cleanups for ProTeX
984    o add version info (via BUILD_INFO.h) to MNC and stdout
985    
986    checkpoint54e_post
987    o add two new packages
988      - pp81 (Packanowski and Philander, 1981), Richardson number and
989        stratification dependent mixing
990      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
991      - these scheme operate in a similar manner as KPP (without ghat, of
992        course), however there is only one diffusivity that is used for both
993        temperature and salinity (and passive tracers)ç
994    o add offline package
995    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
996      provided by Stephanie Dutkiewicz
997    o genmake2: add ability to search for C compilers and cleanup test output
998      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
999    
1000    checkpoint54d_post
1001    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1002    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1003      leading to additional shift by 5 days each year of integration
1004       (i.e. leading to considerable offset over the years)
1005    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1006    o start with no AB and no initial filtering (staggerTimeStep):
1007      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1008    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1009      (external loading & cpl import/export stay in forward_step.F)
1010    o update coupling interface to work with new staggerTimeStep
1011    o change MDSIO ptracers_pickup.
1012    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1013    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1014    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1015    
1016    checkpoint54c_post
1017    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1018      this affects (truncation error) output.txt of test-exp:
1019       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1020    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1021    o change Qnet to always be the net heat flux, (+upward).
1022      affects (truncation error) output of natl_box exp.: updated
1023    o define the max number of passive tracers in PTRACERS_SIZE.h
1024    o start to test mnc routinely in exp0
1025    o add sea-ice loading (sIceLoad) as a new forcing field.
1026    
1027    checkpoint54b_post
1028    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1029       impressive on Altix and Opteron systems)
1030    o diagnostics can now write NetCDF files through the mnc package
1031    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1032    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1033    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1034      affects (truncation error) output of lab_sea & natl_box exp.: updated
1035    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1036    
1037    checkpoint54a_post
1038    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1039    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1040    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1041    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1042      + internal_wave (shift in writing cg2d_ini_res)
1043    checkpoint54a_pre
1044    
1045    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1046      - modified verification/lab_sea and natl_box_adjoint accordingly
1047    
1048    checkpoint54
1049    checkpoint53g_post
1050    o prepare splitting of thermodynamics: store convect.counter in common block
1051    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1052      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1053    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1054    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1055    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1056    o restore adjointability
1057    
1058    checkpoint53f_post
1059    o modifications that affect AIM experiment results (update output.txt):
1060      - no advection of S at top interface Nr (pkg/generic_advdiff)
1061      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1062    o AIM pkg:
1063      - include stability function into surf.Flux derivative relative to Tsurf
1064      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1065    
1066    checkpoint53e_post
1067    o merged cylindrical coord configuration
1068    o added rotating_tank experiment
1069    checkpoint53e_pre
1070    
1071    checkpoint53d_post
1072    o faulks upgraded: re-generate output.txt that have changed:
1073       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1074    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1075    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1076    o added Sadourny discretization of Coriolis
1077      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1078      - re-enabled use of omega3 (useAbsVorticity)
1079    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1080      vector-invariant equations
1081      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1082    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1083      hopefully without new bugs
1084      - still to do: biharmonic friction for non-hydrostatic w
1085    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1086    o regenerated output for global_ocean_ebm (using -ieee)
1087    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1088      of mom_common/
1089      - simple re-arrangement of instructions within computing loop
1090    checkpoint53d_pre
1091    
1092    checkpoint53c_post
1093    o new version of coupler for AIM+thSIce and Ocean models
1094     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1095     - land: change Evaporation of snow
1096     - aim with thSIce: fix bug in snow-precip.
1097    o changes to calc_gw.F
1098     - bug fix for w^2 term near the bottom boundary
1099     - (hopefully) improve the lateral slip boundary condtions for use with
1100        partial/looped cells
1101      - because the bug fix changes two verification experiments anyway (exp5
1102        and plume on slope), change the lateral boundary condition from half slip
1103        to the value of no_slip_sides
1104    o ebm package wasnt quite up to the parallel task. Fixed that.
1105    o Adjoint of EBM package + verification
1106      * TLM OK
1107      * ADM not sufficient accuracy yet (needs further testing)
1108    
1109    checkpoint53b_post
1110    o Commiting new energy balance model to repository
1111      * package is pkg/ebm
1112      * verif. is verification/global_ocean_ebm
1113      * references are in ebm_driver.F

1126    o Will need long integration testing.
1127    checkpoint53b_pre
1128    
1129    o created pkg/mom_common in preparation for variable viscosity code
1130    o renamed and split ini_mnc_io
1131    o pkg/land: only liquid water can diffuse or run-off
1132    o AIM using land: soil wetness availability account for snow
1133    o added printMapIncludesZeros to EEPARMS namelist
1134    
1135    checkpoint53a_post
1136    o restore TAMC compatiility for exf_constants.h
1137      (no usage of _d in .h)
1138    o Additional storing in KPP in an attempt to fix
1139      TAMC problem with adjoint of KPP code.
1140      (no success...)
1141      Identical code works fine with TAF.
1142    o Fixed verification/natl_box_adjoint experiments.
1143      Initial conditions for Experiments 4 and 5 are now
1144      set to "SEAICE_initialHEFF=0", which is more reasonable,
1145      and hence gives results closer to that of Experiment 2.
1146      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1147    
1148    checkpoint53
1149    o stable checkpoint with up to date adjoint
1150      TLM tests only run for 1st grdchk at the moment. Its unclear if
1151      this is a code problem or a problem with resetting code for g_
1152      variables that is being autogenerated wrong.
1153      Otherwise:
1154       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1155       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1156         are both still in chaos following their security messes.
1157    
1158    checkpoint52n_post
1159    o various build (mostly genmake2) changes including:
1160      - ability to build/run more easily within Cygwin and MacOS X
1161      - more complicated Makefiles with a stronger dependence on Gnu Make
1162    o pkg/seaice modifications
1163      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1164        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1165        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1166      - changed proxy for geostrophic velocity and updated
1167        verification/lab_sea/results/* accordingly
1168      - removed ADI dynamic solver from pkg/seaice
1169      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1170        they caused a segmentation fault under certain circumstances
1171      - removed unused field WATR
1172    o bug fix in exf-package:
1173      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1174         now reflect that.
1175    o small fixes in the cal-package:
1176      - set reference date to first of January for the 'model'-calendar
1177      - failing of cal_CheckDate in cal_FullDate now actually results in a
1178        warning
1179    o small modifications in exf-package to increase flexibility:
1180      - change climtempfreeze from a constant to a runtime parameter that
1181        is specified in data.exf_clim (default = -1.9)
1182      - introduce runtime parameter windstressmax (default = 2.0) that is
1183        specified in data.exf
1184    o fix in pkg/thsice:
1185      - update Evap (Tsf changes) to be consistent with Latent heat flux
1186      - maintain snow precipitation unchanged (even if Tsf >=0).
1187     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1188    
1189    checkpoint52m_post
1190    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1191      this does not change any of the results, because myIter=0 in swfrac always
1192      lead to jwtype=2 (the default anyway), but the call makes little sense
1193      as a default
1194    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1195    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1196      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1197    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1198    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1199    o extending useSingleCpuIO option to work with new exch2 I/O format
1200      - old-style, missing-tile I/O is still accessible by defining CPP
1201        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1202    o monitor package can write to NetCDF files and/or STDOUT
1203    o fix re-definition bug in MNC_GRID_INIT_ALL()
1204    o doc/api_reference added
1205      - a framework for building an API Reference Manual using all
1206        the "protex" comments embedded in the code
1207      - see pkg/generic_advdiff, pkg/mnc for examples
1208    o MNC:
1209      - make myThid the last argument for all subroutines
1210      - new default for the grid files: NO halos
1211      - add useMNC and other run-time flags
1212      - separate per-file-group handling of the unlimited dimension
1213      - early initialization of MNC w/ flags read at the eeboot stage
1214        and lookup tables set in initialize_fixed
1215      - write all MNC output to a freshly-created directory
1216    o thermodynamics sea-ice (thsice) is now tested with testreport.
1217    o test exp. advect_cs: use the standard cs32 grid ; update output.
1218    o Added functionality to grdchk:
1219      pick global i,j,k position (or nearest wet) where to perform check.
1220    
1221    checkpoint52l_post
1222    o new land formulation:
1223      a) use ground enthalpy as prognostic variable to ensure exact
1224         energy conservation.
1225      b) account for water temperature and for latent heat of freezing
1226         in all processes (rain, run-off, ground storage)
1227      c) compute surface and ground temperature implicitly.
1228    o aim_v23 modification for new land model:
1229      a) Treat separately land / ocean / sea-ice surface fluxes
1230         to allow implicit computation of land & sea-ice surface temp.
1231      b) add snow precipitation.
1232    checkpoint52l_pre
1233    
1234    o fix problem (when 1 tile is empty) in min/max monitor.
1235    o fix bug in timeAve (u,vZetatave in common block)
1236    o no restoring terms under ice for pkg/seaice
1237    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1238    o bug fix for pkg/seaice pickups
1239    o change MNC call locations and add coordinate attributes
1240    o mask vorticity at the corner ; affects global_ocean.cs output
1241    o fix ini_curvilinear_grid ; test CS experiments with mpi
1242    o aim.5l_cs: modify sea-ice fraction input file ; update output
1243    o exf: Adding simple range check routine for exf fields after read
1244    
1245    checkpoint52k_post
1246    o removed top-level directory "diags"
1247      - we migrated these functions to pkg/timeave a long time ago
1248    o fixed bug introduced in pkg/monitor
1249    o accuracy ctrlprec = 32 insuffient for gradient checks using
1250      averaged fields (I/O via cost_averages)
1251      -> use ctrl.h in active_file*.F to control I/O precision.
1252    o paramter list of CALL ADTHE_MAIN_LOOP
1253    o added initial do_the_model_io to ecco
1254    o set all ...Freq to zero after cost_final
1255      taveFreq, dumpFreq, pChkptFreq
1256    o MAIN and ECCO differentiability restored
1257    
1258    checkpoint52j_post
1259    o fix nchklev in tamc.h for global_ocean...
1260    o Bringing flow and store directives up-to-date
1261    o Really weird thing!
1262      call do_the_model_io from the_main_loop with parameters
1263      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1264      TAF places a faulty re-call of initialise_varia
1265      after cost_final call which should not be there!
1266    checkpoint52j_pre
1267    
1268    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1269      error messages
1270    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1271    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1272      debug output
1273    o modfied mdsio_writefield.F to handle non-global files under exch2
1274    o update AIM Cubed-Sphere exp (aim.5l_cs):
1275      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1276    o update AIM Equatorial Channel exp:
1277      use standard aim_v23 pkg and change the SST fields to be more realistic.
1278    o globalFile now works with exch2
1279    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1280      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1281    o limit timeave output for hi-res integrations
1282    
1283    checkpoint52i_post
1284    o removed CPP_EEOPTIONS.h from verification/*/code
1285    o updated the tiling for global_ocean_pressure
1286    checkpoint52i_pre
1287    
1288    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1289      the old pkg/aim).
1290    
1291    checkpoint52h_pre
1292    o shortened offending lines in exch2_send_rx?.template
1293    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1294    o genmake2: add build & execute test for NetCDF code
1295    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1296      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1297    o added useSingleCPUIO flag to monitor.F and mon_out.F
1298    o added temporary hack for sea-ice dynamics on the cube:
1299      metric terms are ignored and it is assumed that
1300      there is no sea-ice on cube faces 1, 2, 4, and 5.
1301    
1302    checkpoint52f_post
1303    o added exch2 cube routines to pkg/exch2
1304    o modified hs94.cs-32x32x5 to use it
1305    o added new grid files to hs94.cs-32x32x5
1306    checkpoint52f_pre
1307    
1308    checkpoint52e_post
1309    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1310      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1311    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1312      to work with implicit vertical advection and AB ;
1313    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1314    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1315     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1316    checkpoint52e_pre
1317    
1318    o fix bug in impldiff when Nr=1 or Nr=2.
1319    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1320    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1321    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1322      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1323    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1324    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1325    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1326    
1327    checkpoint52d_post
1328    o re-tiled many expts to allow comparison in multi-processor mode
1329      - updated output accordingly
1330      - changed hs94.128x64x5 to use intial T from file rather than use the
1331        random number generator
1332    o add infrastructure in model routines for fizhi and gridalt packages
1333    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1334    o changes to permit hi-res, cubed-sphere, configuration
1335      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1336      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1337      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1338        of surface winds for the cube
1339      (A verification experiment, based on global_ocean.cs32x15, but with
1340       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1341       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1342       complete with example surface forcing files and matlab scripts to look
1343       at the output and compare it with that of global_ocean.cs32x15.)
1344    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1345       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1346       to conform to the common rule.
1347    o check-in the first version of the coupler + interfaces for multi-components
1348       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1349       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1350       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1351       - ocean and atmos. share the same horizontal grid (no interpolation).
1352       - exchanges between component and coupler is done in forward_step
1353    o new verification experiment, cpl_aim+ocn:
1354       coupled ocean - AIM atmosphere on cs32 grid.
1355    
1356    checkpoint52d_pre
1357    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1358    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1359    
1360    checkpoint52c_post
1361    o Fixing OPTIONS files for use of exf:
1362      - ALLOW_ECCO not needed
1363      - ECCO_CPPOPTIONS.h should not be included from
1364        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1365        as has been the case in the past
1366      - All cal/exf related options are currently set in
1367        single header file. Should remain so until we
1368        agree on a consistent new policy.
1369    o Removed all CPP options for cal package.
1370      cal has no more CPP options.
1371    o modified STOREs in GAD_ADVECTION
1372    o corrected key comp. for passkey
1373    
1374    checkpoint52b_post
1375    o new version: "thsice" of thermodynamic sea-ice pkg:
1376     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1377     - modify fluxes but do not change theta directly;
1378     - light cleaning of bulk_force pkg (still needed with thsice).
1379     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1380       + output_thsice.txt to test thsice & bulk_force pkgs.
1381    o put back grid & coriolis monitor output.
1382    checkpoint52b_pre
1383    
1384    o call "do_the_model_io" at the beginning (=> dump initial state)
1385    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1386    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1387      (need info on NUMBER_OF_PTRACERS)
1388    o missing PTRACERS headers in some routines
1389    o default tamc.h in pkg/autodiff supposed to crash
1390      to ensure proper customization
1391    
1392    checkpoint52a_post
1393    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1394      - moved surfaceTendencyTice from pkg/seaice to main code
1395      - subroutine FREEZE_SURFACE now limits only surface temperature
1396        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1397        => new output.txt for global_ocean.cs32x15 & global_with_exf
1398      - keep the old version of FREEZE for backward compatibility;
1399        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1400      - corresponding modifs for TAF directives
1401    o added surface flux output variables to TIMEAVE_STATVARS
1402    o time-averaged output for pkg/ptracers
1403    o fix problem with ECCO-related divided adjoint
1404      snapshot file was missing some ad-variables,
1405      but no warning issued by TAF
1406    
1407    checkpoint52a_pre
1408    o some bug fixes for #undef REAL4_IS_SLOW
1409    
1410    checkpoint52 = ecco_c52_e35
1411    o after testing adjoints of checkpoint51u_post
1412    
1413    checkpoint51u_post
1414    o this is the post-merge tag of the ecco-branch
1415      (needs another clean checkout and re-testing)
1416    o various natl_box_adjoint configs and results
1417      but no input fields
1418    o obcs adjoint not yet merged!
1419    o adding ECCO global 1x1 and 2x2 degree configs
1420    o updated/extended some store directives for seaice
1421    o pkg/ecco now containes ecco-specific part of cost function
1422    o top level routines the_main_loop, forward_step
1423      supersede those in model/src/
1424      previous input data.cost now in data.ecco
1425      (new namelist ecco_cost_nml)
1426    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1427    
1428    checkpoint51t_post
1429    o this is the pre-merge tag of the ecco-branch
1430    
1431    checkpoint51s_post
1432    o cleanup: removed various obsolete #define-s
1433    o pkg/grdchk
1434      - renamed 'ph-grd 3' to 'grad-res'
1435      - merged from ecco-branch
1436        (remaining bug fixes for obcs gradient checks)
1437      - additional high-precision output for testreport
1438        (grep for 'precision_grdchk_result')
1439    
1440    checkpoint51r_post
1441    o cleaned up or removed CPP_OPTIONS.h files
1442    o updated results for some of the tests to reflect the new
1443      optfiles (-ieee: -O0 instead of -O3)
1444    
1445    checkpoint51q_post
1446    o cd_code:
1447      - moved cd_scheme.F -> cd_code_scheme.F
1448      - separate read_checkpoint from cd_code_ini_vars.F
1449      - separated cd_code part from write_checkpoint
1450      - updated AD_SOURCE, generated .flow
1451      - added CD_CODE_VARS.h to the_main_loop
1452      - Moving cd_code specific store dir.s to pkg/cd_code
1453    o ctrl package totally restructured
1454      - pack/unpack now optional and decoupled from
1455        xx_/adxx_ I/O
1456      - ctrl_pack/unpack cleaned
1457        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1458      - confined inclusion of AD_CONFIG.h to where necessary.
1459    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1460    
1461    checkpoint51p_post
1462    o create initial cd_code package
1463      - WARNING: the initialization of fields within packages
1464        is broken because INI_FIELDS (where READ_CHECKPOINT is
1465        called) is called *before* PACKAGES_INIT_VARIABLES.
1466        This seems to be backwards since
1467        1) its important to initially zero the entire field including
1468           the "halo" region
1469        2) zeroing needs to be done *before* reading pickup info
1470           and the pickup call might or might not happen in any
1471           particular run
1472      - this needs an overhaul for R2
1473    o cleanup verification/*/code/GMREDI_OPTIONS.h
1474    o cleanup testreport
1475    
1476    checkpoint51o_post
1477    o bringing AD-related verif's up to date with genmake2
1478      - carbon/
1479      - global_ocean.90x40x15/
1480      - hs.94.1x64x5/
1481      - (front_relax/ )
1482    o (more) consistent directory structure for AD-related verif.'s
1483    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1484    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1485    o bug fix in find_alpha.F for MDJWF:
1486      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1487        change rho -> rho-rhoConst
1488      - replace call find_rho to find_rhonum
1489    o initialisation of rFlx extended to full array (required by TAF)
1490      and shifted to thermodynamics

1651    o made ptracers_forcing same as external_forcing_s
1652    o added verification for adjoint with ptracers
1653      - adm. grdchk fail so far
1654      - tlm. grdchk OK
1655      - checked tapelev/comlev recomputations: OK
1656    <<<checkpoint51b_pre

1664    
1665    checkpoint51
1666    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1667      - autodiff, ctrl, exf, grdchk, seaice
1668      kept separate packages
1669      - cost, ecco, obcs
1670    o updating verification/internal_wave, verification/lab_sea
1671      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1672    
1673    checkpoint50i_post
1674    o Preparing next differentiable checkpoint and sync
1675      of MAIN vs. ecco-branch
1676      - 1st step: this one is differentiable
1677      - 2nd step: next(! not this) checkpoint will have updated packages
1678                  from ecco-branch)
1679    
1680    checkpoint50h_post
1681    o new package "land": provide surface BC for AIM.
1682    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1683    o AIM: use true log-P extrapolation for near surface temp (= as in

1685    o New variable in PARM03 for more flexible pickups
1686    o somewhat cleaned package initialisation sequence for
1687      ctrl/ cost/ ecco/ in packages_... routines
1688    
1689    checkpoint50g_post
1690    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1691      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1692      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1693        made the default because of faster convergence than ADI
1694    
1695    checkpoint50f_post
1696    o exf totally restructured
1697      - replaced all exf_set_ routines by one generic exf_set_gen.F
1698        and made sure it's still differentiable
1699      - split exf_getffields.F into new exf_bulkformulae.F
1700      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1701      - updated adjoint/makefile and relevant verif. accordingly
1702

1712    
1713    checkpoint50e_post
1714    o make KPP work with PTRACERS
1715     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1716       nearly a copy of kpp_transport_s
1717     - there is no analogue to SurfaceTendencyS, so I have to use
1718       gPtr(of the surface layer) instead
1719    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1720    checkpoint50e_pre
1721    
1722    checkpoint50d_post
1723    o change kpp output from multiple-record state files to single-record state
1724      files analogous to write_state.F
1725    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1726      analogous to the cg2d-related output.
1727    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1728      so that writing to internal file fn (with length 512) fails.
1729    checkpoint50d_pre
1730    
1731    checkpoint50c_post
1732    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1733    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1734    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1735    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1736    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1737    
1738    checkpoint50c_pre
1739    Merging from release1_p13:
1740    o bug fix for pkg/seaice dynamic solver
1741    o Added SEAICE_initialHEFF to pkg/seaice
1742    
1743    checkpoint50b_post
1744    o store u*,v* in gU,V instead of in guNm1,gvNm1
1745    o in order to put the momForcing out of the Adams-Bashforth:
1746      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1747      to timestep.F
1748    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1749    o re-generate output for highly sensitive test-exp:
1750       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1751    
1752    checkpoint50b_pre
1753    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1754    o corrected CPP option mismatch in exf_Bulk... functions for case
1755      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1756    
1757    checkpoint50a_post
1758    o Bug fix for merging between c50 and KPP.
1759      ikey was passed from thermodynamics to kpp_calc via
1760      common block rather than being recomputed in kpp_calc,
1761      in contradiction with new key itdkey.
1762      New key ikppkey created, and tamc.h headers updated.
1763    
1764    checkpoint50
1765    - 2nd step of merge with ecco-branch:
1766      merge changes in ecco-branch back into main trunk
1767    - bug fix in find_alpha
1768    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1769    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1770    - merged some sliced AD support routines
1771    
1772    checkpoint49
1773    merged from ecco-branch:
1774    o exf:
1775      - Enable initialisation of forcing fields to constant
1776        (runtime) values.
1777      - in exf_getffields.F
1778        Reduce i-/j-loop to interior domain, discarding overlaps.
1779        That also fixes wrong TAF-key computations for key_1, key_2
1780        with bulf formulae.
1781      - exf_init.F modify #ifdef for exf_init_evap
1782      - exf_getffieldrec.F, ctrl_getrec.F
1783        The following INT-usages are not safe:
1784          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1785          fldcount = int(fldsecs/fldperiod) + 1
1786        and were modified.
1787    o autodiff: checkpoint_lev...
1788      - updated storing for bulk formulae (some arrays were missing)
1789      - added state for seaice package
1790      - synchronized with main branch
1791    o DIVA:
1792      Modif.s in
1793      - the_main_loop.F
1794      - the_model_main.F
1795      and added cost_final_restore.F cost_final_store.F
1796      o With these changes, it is possible to fully separate
1797        the first forward run to compute the cost function (mdthe_main_loop)
1798        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1799        into separate model executions.
1800        This enables better tuning of DIVA to given queue sizes.
1801      o Loss of cost function value in consecutive DIVA runs is
1802        fixed by storing to 'costfinal' file.
1803      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1804        beginning/end of adjoint integration is accounted for.
1805      The current changes apply to TAF-1.4.26.
1806      TAF has one remaining bug, requiring one manual change
1807      (see MITgcm manual).
1808    o cal: synchronized between MAIN and ecco-branch
1809    
1810    checkpoint48i_post
1811    o Changes to restore differentiability of code w.r.t. previous tag
1812      (mostly adding new routines to make list and replacing
1813      pressure by totPhiHyd).
1814    o Updated and merged grdchk package
1815      - has both ADM and TLM checks
1816      - works for single- and multi-proc.
1817      - output cleaned
1818      - worked successfully for parallel DIVA
1819    o genmake:
1820      - Adding -platform=SP4
1821      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1822    o Modif. for DIVA:
1823      ctrl_unpack should not be called in intermediate DIVA interval.
1824      (similar thing would apply for active files such as
1825      tbar, sbar, psbar, which should not be reinitialised;
1826      only relevant for ecco-branch)
1827    
1828    checkpoint48h_post
1829    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1830    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1831    o Added SEAICE_initialHEFF to pkg/seaice
1832    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1833    
1834    checkpoint48g_post
1835    --- EOS:
1836    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1837      store total Potential in totPhyHyd for diagnostics & EOS.
1838    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1839    --- Pressure/geopotential gradient:
1840    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1841    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1842      ( changes results of global_ocean_pressure )
1843    o NLFS + z-coord.: add eta*Rho' contribution.
1844    o accurate phiHyd when using interface-W at the middle between 2 centers
1845     ( changes results of ideal_2D_oce )
1846    o includes r* 2nd term in potential gradient.
1847    
1848    checkpoint48f_post
1849    Merging from release1_p12:
1850    o Modifications for using pkg/exf with pkg/seaice

1856      (SBO) core products, including oceanic mass, center-of-mass,
1857      angular, and bottom pressure (see pkg/sbo/README.sbo).
1858    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1859      to avoid negative values in shallow regions.
1860      - updated verification/natl_box/results/output.txt
1861      - updated verification/lab_sea/results/output.txt
1862    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1863    o Added useSingleCpuIO option (see PARAMS.h).
1864    o Updated useSingleCpuIO option in mdsio_writefield.F to
1865      work with multi-field files, e.g., for single-file pickup.
1866    o pkg/seaice:
1867      - bug fix in growth.F: QNET for no shortwave case
1868      - added HeffFile for specifying initial sea-ice thickness
