5      ==============================      ==============================
6    
7  untagged  o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
8      to pkg/seaice):
9      - new routines thsice_map_exf and thsice_get_exf provide the interface
10      - add an additional formal parameter to thsice_solve4temp
11    o pkg/exf:
12      - add new fields wspeed, snowprecip (to be able to couple to thsice)
13      - correct Stefan-Boltzmann constant
14      - new parameter for longwave surface emittance
15      - separate some stuff from exf_bulkformulae into new routines  
16        exf_radiation, exf_wind
17      - add new parameters and constants: longwave emissivity for ocean, ice
18        and snow, evaporation parameters over ice
19    o pkg/thSIce:
20    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
21    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
22       and THSICE_CALC_THICKN
23    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
24    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
25      to make debugging easier.
26    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
27    o pkg/bulk_force:
28      - clean-up comments and parameters ;
29      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
30    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
31      generate new output for test-experiment: aim.5l_cs.thSI
32    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
33      testreport accordingly
34    
35    checkpoint58e_post
36    o SEAICE_CGRID adjoint done
37    o R_STAR adjoint implemented.
38      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
39      * need to sort out init. of h0facc, etc.
40    o Make pkg/profile fully independent of ecco,cost, etc. stuff
41      to be able to use it in pure forward.
42    
43    checkpoint58d_post
44    o upgrade simple test-experiment to tutorial example:
45     step.1: duplicate the experiment and (step.2) will remove the old copy.
46      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
47      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
48      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
49      tutorial_global_oce_biogeo    <- copy of dic_example
50      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
51      tutorial_plume_on_slope       <- copy of plume_on_slope
52      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
53      tutorial_global_oce_optim     <- empty for now (David ?)
54      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
55     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
56    o correct a sign problem in cost_scat.F
57    o obcs and ptracers: fix boundary conditions for advections schemes
58      with larger stencil
59    o thsice adjoint: start
60    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
61      completeness
62    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
63      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
64    o ptracers adjoint:
65      * avoid extensive recomputatations
66      * fix missing re-init. of gptr (missed by TAF)
67    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
68      me to turn off the excessive output to STDOUT that this package produces
69    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
70      and add those terms in Vector-Invariant formulation.
71    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
72      if the control period (xx_hfluxperiod etc) is 0
73    o in profiles pkg, clean routines and fix details
74    o in ecco pkg, reading ssh data:
75      fix problem in case the model does not start at iter0=0
76    o fix mnc-pickup/restart for ptracers
77    o new package prifiles:
78      code to compute profile-based cost by Gael Forget
79      (modifs in ecco, ctrl, autodiff)
80    o Benign bug fix in initialization (spotted by M. Mazloff) of
81      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
82    
83    checkpoint58c_post
84    o adjoint: finish NLFS adjoint and provide reference output in
85      verification/global_ocean.90x40x15/results_ad_nlfs
86    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
87      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
88      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
89      with SEAICE_CGRID defined.
90    o move calendarDumps from "data" to "data.cal" and clean-up the code
91      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
92    o add useEXF & useCAL flags (for now, set in hard-coded way)
93    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
94      (were missing in NH mode, and wrong in quasihydrostatic mode).
95      waiting for Chris updated version of calc_gw to add those CALLs.
96    o fix bug in quasihydrostatic S/R ;
97      add a test for this option: global_ocean.90x40x15.qshyd
98    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
99      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
100    o add on/off flag useOffLine for package OFFLINE
101    o seaice:
102      - modify advection so that it works also on the C-grid
103      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
104        problem in multi-tile runs with C-grid
105      - add flags for clipping ice velocities and/or masking solver forcing
106      - fix drag (ocean on ice) formulation and a bug that caused noise in the
107        C-grid solver
108      - added a few comments to seaice_diffusion.F
109      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
110        are now exclusive)
111      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
112        required re-ordering the code a little:
113       + make DAIRN global variable (defined in SEAICE)
114       + move computation of the viscosities eta and zeta into a new separate
115         routine (because I need to recompute them in seaice_ocean_stress.F)
116    
117    checkpoint58b_post
118    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
119      update output.txt of exp. aim.5l_cs.thSI
120    o various mnc cleanups and improvements:
121      + shrink lookup tables by factor of ~4
122      + better error reporting when running out of lookup space
123      + able to handle longer path/file names (up to 500 chars)
124    o adjoint:
125      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
126      - TBD: "hidden" mom_vecinv recomp. in dynamics
127    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
128     (allow to differentiate between forcing components using new integer flags:
129      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
130     and add new flag to put Dissipation tendency out of Adams-Bashforth.
131    o ecco
132      - enable trend removal from SSH anomaly obs.
133    o adjoint
134      - a fix for PmEpR when #undef EXACT_CONSERV
135      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
136      - try to fix "hidden" recomp. in forward_step for NLFS
137        (NLFS seems broken sometimes after I checked it in)
138    o seaice:
139     - add c-grid version of the dynamic solver:
140       + three new routines that are the c-grid substitute lsr, dynsolver
141         and ostres
142       + put a few fields that were local to dynsolver into global common
143         blocks, so that I can move the computation of stresses etc into
144         seaice_lsr (saves coding but may break the adjoint).
145     - replace more hardwired parameters by runtime parameters
146     - add ice masks that mask the rhs of the implicit solvers where there
147       is no ice (commented out in seaice_dynsolver, because i am not sure
148       if this works properly), eventually this should replace the clipping
149       of ice velocities in seaice_dynsolver to +/-40cm/s.
150    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
151      include it only where its needed
152    o move balancing of fluxes before the call of external_forcing_surf
153    o seaice:
154      - correct units of turning angles (now they are really in degrees)
155      - move computation of GWATX/Y out of main routine into dynsolver
156      - initialize GWATX/Y in seaice_init
157    o Apply mask on Fresh-Water flux (needed for SSH forcing).
158      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
159    o seaice: add runtime flags for turning angles (default to zero)
160    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
161      and trend from exf forcing and ctrl control adjustments
162    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
163      (since checkpoint57x_post)
164    o change the default rotation period to 86164.s = the Earth rotation
165    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
166      and based on a reference stratification. Tested within hs94.cs-32x32x5.
167    o seaice advection: add code for choosing between the default (2nd order
168      central differences) and multiDim advection schemes provided by
169      pkg/generic_advdiff
170    o seaice:
171      - removed all references to SEAICE_GRID.h fields from
172        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
173        (cubed-sphere configuration will change a little)
174      - grid computations in seaice_init are obsolete now.
175      - cleaned up code a little so that is easier to read (hopefully).
176      - added new (better?) discretizations of default advection and diffusion
177        (turn on with SEAICEuseFluxForm)
178      - replace 1 in 3d global fields by kSurface in growth.F
179      
180    checkpoint58a_post
181    o seaice:
182      - bug fix in advect.F
183    o shelfice:
184      - separate shelfice load anomaly from pload (breaks with time
185        dependent forcing), => introduce constant field shelficeLoadAnomaly.
186        Its default is 0., but it may be computed more cleverly from (unknown)
187        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
188        done offline. A good approximation of the pressure load anomaly is
189        necessary to avoid large initial adjustment processes underneath
190        deep-reaching shelfice.
191      - small fix in ISOMIP shelfice_thermodynamics
192      - add more sophisticated thermodynamics of Hellmer (1989), this is
193        now the default
194      - give a few constants more intuitive names
195    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
196      if bulk formulae are used in long integration (especially EmPmR). Turn
197      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
198      if balancePrintMean, the imbalance that is substracted is printed to
199      STDOUT.
200    o fix bug (typo) in obcs_apply_eta.F
201    o add a new package shelfice which enables us to model the circulation
202      underneath shelf-ice with draughts of hundreds of meters.
203     - works
204     - to do: + include improved thermodynamics
205              + check whether kSurfC (from model/inc/SURFACE.h) can be used
206                instead of new field kTopC
207              + can we use topoFile, Ro_surf and existing code in ini_depth.F
208                instead of new field R_shelfIce and new code in ini_depth.F
209                and ini_mask_etc.F?
210              + adjust vertical mixing schemes?
211    o seaice pkg:
212     - add a cpp-flag to include a simple formula for a salinity dependent
213       freezing point of sea water at the surface
214     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
215       meridional stresses are now different (and hopefully correct)
216    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
217       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
218       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
219    o pkg/diagnostics: add options and parameters for regional-statistics
220       diagnostics ; define regions by reading a region-mask from a file
221       (might add other options later)
222    o pkg/bulk_force:
223     - add option and parameters to use AIM surface-flux formulae.
224     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
225       others forcing fields (defined in PARM05, parameter file "data") are loaded
226       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
227     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
228     - use the right EXCH call for uwind,vwind (to work on CS-grid).
229     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
230       and parameters (note: calcWindStress replaces .NOT.readwindstress).
231     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
232    
233    checkpoint58
234    o add "--embed-source" option to genmake2 which, when the supporting
235      tools can be compiled (as determined by genmake2) will turn on the
236      embed_files package which then embeds the entire MITgcm source code
237      (*.[fFhc] + Makefile) used for the build within the executable
238      - requested by CNH but off by default
239      - adds a paltry <9MB to the mitgcmuv executable in most cases
240      - only writes the output when useEMBEDSRC in eedata is true
241    o clean up 3-dim. relaxation codes:
242      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
243      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
244      * Thanks to Tom Haine for testing!
245    
246    checkpoint57z_post
247    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
248      affects output (@ truncation level) of exp. plume_on_slope ; updated.
249    o fix the pickup behavior for obcs in combination with ptracers
250    o fix a bug in ptracers_external_fields_load
251    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
252      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
253    o transfered surface NH pressure to eta field (if exactConserv).
254    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
255         and update lab_sea output.txt file.
256    o completing 3-dim. relaxation code: additional term
257         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
258      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
259      * At compile time, in "EXF_OPTIONS.h" set
260          #define  ALLOW_CLIMTEMP_RELAXATION
261          #define  ALLOW_CLIMSALT_RELAXATION
262      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
263          tauThetaClimRelax3Dim = 15552000.0,
264          tauSaltClimRelax3Dim  = 15552000.0,
265      * 3 cases:
266          1) Use a constant-in-time 3-dim. field
267          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
268          3) Real-time relax. to time-evolving prescribed field
269    o Adding Laplacian-type smoothness constraint on
270      initial and boundary (forcing) controls (ic, bc)
271      * enable at compile-time via
272        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
273      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
274      * Absolute scale somewhat unclear so far
275      * no area weighting was included since no other cost term does so far
276    
277    checkpoint57y_post
278    First step for a NLFS adjoint
279    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
280    o new init. routines for calc_r_star, calc_surf_dr
281    o still need to deal with ini_masks_etc
282    o testreport seemed happy
283    checkpoint57y_pre
284    
285    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
286    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
287    o add new offset feature to offline pkg (plus minor cleanup)
288    o cfc fixes for final year of integration
289    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
290      be in GCHEM_OPTIONS).
291    
292    checkpoint57x_post
293    o fix testreport Pb in multiple test experiment.
294    o cleanup our namelist syntax in verification:
295      - make it more F95 standards compliant (some work still needed)
296      - allows the vast majority of our tests to work with gfortran
297    o Non-Hydrostatic:
298     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
299     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
300    o Allow to apply AB on T,S rather than on AB(gT,gS):
301     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
302     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
303       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
304     - need a "clever" read_pickup to restart from the other AB formulation
305    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
306    o remove some unused variables (reduces number of compiler warnings)
307    o adjoint
308      * Disable useVariableViscosity for adjoint for time being
309        (there are a number of extensive recomputations)
310      * Initialize certain variables needed for adjoint
311    
312    checkpoint57w_post
313    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
314                 fix the singleCpuIO RS version of MDSWRITEFIELD
315       and add a WARNING if using globalFiles=T with multi-processors.
316    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
317      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
318    o tracer advection scheme:
319      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
320       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
321       was not very convenient).
322      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
323       (further tests needed for the implicit DST & Flux-Limiter schemes).
324    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
325      and sRef for convenience, handy, when you want to initialize
326      ptracers in a large domain with a constant non-zero value. Also,
327      untangle ptracers_init.F a little.
328    
329    checkpoint57v_post
330    o change dome exp. to use variable viscosity in side-drag terms.
331    o remove all the files from the cfc_offline test since they are now
332      incorporated into tutorial_cfc_offline which has been producing
333      identical results for a few days of testing
334    o add new parameter: sideDragFactor to enable half-slip-side BC
335      and change side-drag S/R to use viscosity from mom_calc_visc
336      (can switch back by setting sideDragFactor=0.); affects results at
337      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
338       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
339    o vorticity & strain are now computed without masking, to account for
340      no-slip-side BC in variable viscosity calculation ; mask is applied
341      anyway later on, before computing advection/coriolis terms.
342    o modify exp4 to test new obcs support for reading from external files
343      and for passive tracers
344    o fix behavior of ptracers_monitor when monitor output is written to a
345      netcdf-file; still not independent of monitor.F (writes in the same
346      file).
347    o change default value of tRef (put a uniform, meaningful value for ocean
348      & atmos) and initialize sRef (was missing, as Martin mentioned).
349    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
350      to be proportional to enstrophy dissipation length.  Thus,
351       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
352      This is now consistent with Smagorinsky and with the manual.
353    
354    checkpoint57u_post
355    o OBCS and PTRACERS: add open boundary support for passive tracers
356      - either use homogenous (pseudo) v.Neumann conditions or prescribe
357        OB-values from file; this is not different from the way theta and salinity
358        are treated
359      - however, Orlanski-radiation conditions are not supported, and the model
360        will stop if you use pTracers and Orlanski at the same time.
361      - beefed up the rountine obcs_external_fields_load: now only those open
362        boundary values are overwritten with values from files for which there
363        are really files, otherwise the OB-fields remain untouched. This makes
364        it possible to use different OBs at different ends of the domain (as
365        with EXF)
366    o reduce number of exch calls in shap_filt (s2).
367    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
368      truncation level) 4/5 MLAdjust test results (11&12 digits match).
369    
370    checkpoint57t_post
371    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
372    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
373      same truncation, independent of the face number: affects affects several
374      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
375    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
376      note that biharmonic viscosity + no-slip was not tested in any experiment.
377    o fix bug in non-linear free-surf side-drag ; generate new output for
378      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
379    o make mnc honor the writeBinaryPrec flag for most kinds of output
380    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
381    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
382      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
383    o add brackets in multi-terms sum to get same truncation, independent of
384      the face number (manage to get exactly same value of gU,gV at the cs-edge)
385      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
386    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
387      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
388      a maximum grid-scale Reynolds number.  Also, changes all length calculations
389      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
390      Suggested values of viscosity parameters found in mom_calc_visc.
391      Many new viscosity diagnostics available.
392    
393    checkpoint57s_post
394    o Add clearing-house for viscosity calculations, mom_calc_visc and
395      correct numerous bugs in LeithD and Smagorinsky discretizations.  
396      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
397      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
398      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
399      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
400      The Strain-Tension form is now called with useStrainTensonVisc=.true.
401      ViscAhStrain and viscAhTension are now retired.
402    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
403    o In response to JMC's bug report, genmake2 now ignores any soft-links
404      that it finds in the *current* directory when searching for files.
405      Soft-links found in any other source directories will still work as
406      they did before.
407    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
408      a C routine to unlimit the stack size
409    o mnc-ify pkg/aim snapshot vars
410    o mnc-ify pkg/land as requested by Daniel
411    o various changes to mnc including:
412      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
413      - output can now be grouped so that all files within a group
414          change the ITER portion of their names in lock-step together
415      - can now read ("global") PER-FACE (in addition to PER-TILE) files
416          and works with both EXCH1 and EXCH2 (but needs more testing)
417      - writing works for all verification test cases w/ g77 on Linux
418    
419    checkpoint57r_post
420    o make MNC variable initialization happen earlier
421    o add diagnostics for (almost) each term of the momentum Eq.
422    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
423    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
424    o remove MINIMAL_TAVE_OUTPUT option ;
425      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
426    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
427      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
428    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
429    o add time-dependent SST, SSS control
430    o cost terms in ecco/ modularized (new cost_generic.F)
431    o cost_averages routines are modularized (new cost_averagesgeneric.F)
432    o new infrastructure for seaice model vs. obs misfits in seaice/
433      * driver from the_main_loop.F is seaice_cost_driver.F
434      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
435      * gradient check in Exp. 6a of natl_box_adjoint/
436    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
437      (see README file)
438    
439    checkpoint57q_post
440    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
441    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
442      - bug was reported by Jean-Michel and Ian Fenty
443    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
444      update exp. cpl_aim+ocn output.
445    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
446      Needed for high-res. runs with large global files
447      to be able to limit tapelev size
448    o Changed some tests for adjoint:
449      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
450      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
451      * global_ocean.90x40x15/ back to default 3-level checkpointing
452    o Modifications to enable scripted COMMON to MODULE conversion
453      * verification/OpenAD/code/ has necessary scripts and description;
454      * converts, compiles and runs successfully;
455    
456    checkpoint57p_post
457    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
458    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
459      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
460    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
461    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
462      (was already the case for dissipation with mom_vecinv,
463       and also the case for grad.PhiHyd when staggered-timeStep)
464      This will allow to put dissipation out-off the AB time-stepping.
465     Unfortunately, affects truncation error. Update output of exp. that "fails"
466      (cg2d matching number) and leave the others for later: front_relax(10),
467      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
468      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
469    
470    checkpoint57o_post
471    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
472      (2) its ready to be documented during the 20050801 DocFest
473    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
474      for ideal_2D_oce and lab_sea on linux_ia32_g77
475    o set to #undef CTRL_SET_OLD_MAXCVARS_30
476      in global1x1_tot/code_seaice_adj to access indices 32, 33
477      (worth another tag)
478    
479    checkpoint57n_post
480    o adding precip control xx_precip 32
481    o adding swflux control xx_swflux 33
482    o Replacing 10 forcing penalty cost routines by 1 generic.
483    o Implementing partitioning in time-mean and variable adjustment
484      for atmos. state.
485    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
486    o in natl_box_adjoint:
487      * updated exp 1 to 10
488        (but does not have time-mean vs. variable split results yet)
489    o updated global1x1/*_seaice_adj/
490      to incorporate latest changes
491    o enable useSingleCpuIO for mdsio vector routines
492      (applies in particular to tapelev I/O)
493    o removed inefficient K-loop in all active_file*control*.F
494    
495    checkpoint57m_post
496    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
497      and advect_cs (use EXCH-2 and standard cs-32 grid files).
498    o pkg/exch2: filling of face-corner halo regions is optional
499      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
500    
501    checkpoint57l_post
502     tag before updating tutorials (pre-release-2)
503    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
504       for output and interpolation of input fields onto model grid)
505    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
506       Affects results of exp. rotating_tank ; update output.txt.
507    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
508          and taking the square quantity and/or using a fraction-weight field.
509    o fix aim_diagnostics_init.F mate numbers.
510    o add mnc output capability to diagnostics/diagstat and update
511      our cvsignore files for the ACSII output generated
512    
513    checkpoint57k_post
514    o lab_sea now uses diagnostics package and provides a suite of
515      new EXF diagnostics output.
516    
517    checkpoint57j_post
518    o exf
519      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
520        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
521        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
522      * extended diagnostics output
523        - now includes all EXF variables
524        - hs, hl moved to common block
525        - separate S/R for diagnostics, called after ctrl vector is added
526        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
527        - EXFqnet contains true Qnet (i.e. includes qsw)
528      * updated verif. lab_sea, global_with_exf
529      * Rearranging hflux (exf_mapfields -> exf_getforcing)
530        to ensure that diagnostics sees a true EXFqnet
531    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
532    o diagnostics pkg: change pointers so that 1 diagnostic can be used
533      several times with different frequencies.
534    o mnc-ify the thsice package as requested by Daniel Enderton
535      - the monitor--MNC output needs work
536      - many attributes need to be added (most are currently blank)
537    o mnc-ify theaim_v23 package as requested by Daniel Enderton
538      - many attributes need to be added (most are currently blank)
539    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
540    o add Sadourny like discretization to the 4th.O vorticity advection scheme
541    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
542      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,

544    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
545     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
546    
547    checkpoint57i_post
548    o Diagnostics package was changed: diagnostic allocation is now deactivated
549      by setting an empty file name in the namelist (used to be by setting 0 frequency)
550    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
551      add 1rst Order upwind vertical Shear.
552    o add a quick fix for A/B checkpointing in OFFLINE mode
553    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
554      end-run around the C/Fortran linking horror in eesup/src/timers.F
555    o added pkg/runclock: allows user to terminate run based on wall clock
556    o added non-hydrostatic scaling parameter: nh_am2
557    o pkg/my82: futile attempt to make results compiler-independent by adding
558      some "_d 0", etc. no effect.
559    o for mnc output, fill the 'T' coordinate var with myTime and create a
560      separate 'iter' variable for iteration count
561    o pkg/diagnostics:
562      add new capability: output of Global/Regional & per-level statistics ;
563      tested against monitor output (including land & thSIce) on various exp.
564    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
565    
566    checkpoint57h_done
567      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
568      data.diagnostics, data.gchem, data.ptracers) is done.
569    
570    o pkg/diagnostics: prepare for Global/Regional statistics.
571      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
572    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
573      and rename it: DIFFERENT_MULTIPLE
574    
575    checkpoint57h_post
576    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
577    o pkg/diagnostics: change output frequency, now in seconds (instead
578      of Nb of iterations). This requires to change data.diagnostics.
579    checkpoint57h_pre
580    
581    o in mnc, let the user create the output dir if both mnc_outdir_date
582      and mnc_outdir_num are false
583    o add fflags() to pkg/diagnostics which allows one to specify, on a
584      per-file basis, the file precision [default behavior is unchanged]
585    o added diagnostics to pkg/kpp, including computation of mixed layer
586      depth based on a temperature/density criterion
587    o updated verification/natl_box to test the new pkg/kpp diagnostics
588    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
589    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
590    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
591      not mnc -- this mistake was found by JMC and is now corrected
592    
593    checkpoint57g_post
594    o add Adams-Bashforth 3rd Order time stepping:
595      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
596      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
597    checkpoint57g_pre
598    
599    o make lambda[Theta,Salt]ClimRelax spatially varying
600      (default remains spatially uniform constant based on tau)
601    o added new control variables
602      * init. uVel, vVel, etanN
603      * lambda[Theta,Salt]ClimRelax
604    o separate masks used for ctrl_pack/unpack 'from write_grid' output
605      (suggested by G. Forget)
606    
607    checkpoint57f_post
608    o add parameter "baseTime" = model base time = time at iteration zero
609      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
610      account for baseTime shift
611    o move Coriolis arrays from PARAMS.h to GRID.h
612    checkpoint57f_pre
613    
614    o mnc-ifying the seaice package
615    o introduced an alternative length scale calculation for use in the limiting
616      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
617    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
618    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
619      as well as grad(vort3).  Made it compatible with both approximate form
620      for the cubed sphere and full form of these gradients.  Added flag
621      useFullLeith to select between approximate and full form.  
622    o add "d0" in getcon.F to reduce differences between compilers/platforms
623      update output.txt of exp. fizhi-gridalt-hs
624    o change port_rand funtion to allow to set the seed.
625    o fix obscure MNC bug involving conversion between reals and integers
626      - it caused no problems with certain (eg. gcc, ifc) compilers but the
627        new version is now more standards-compliant
628    o adjoint-related modifications
629      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
630      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
631      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
632    
633    checkpoint57e_post
634    o Adding eddy stress controls a la Ferreira et al.
635    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
636    
637    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
638      update output.txt of exp. fizhi-gridalt-hs
639    o add more "Z" dimensions and associated coordinate vars to MNC
640    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
641    o parameter calendarDumps: when set, approximate months (30-31 days) and years
642      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
643      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
644      months and years.  Requires pkg/cal.
645    o diagnostics: add pickup functionality
646      - off by default for backwards compatibility
647      - current version only uses MDSIO -- MNC will be added
648    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
649    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
650    
651    checkpoint57d_post
652    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
653    o modify verification/ideal_2D_oce so that it tests the creation of mnc
654      output from the diagnostics package
655    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
656    o make genmake2 more portable by using ".$FS" instead of ".f" for more
657      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
658    o add coordinate variables to the MNC output from the diagnostics package
659    o change MNC-flags default value: true when useMNC=TRUE
660    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
661      the ability (off by default) to read the grid information using MNC
662    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
663    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
664    o do snap-shot diagnostics at the middle of the time-interval (instead of
665      at the end).
666    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
667      new test for AIM with thSIce + slab-ocean
668    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
669    o move state variable diagnostics to the beginning of the time step ;
670      (note: still needs some work specially for snap-shot diagnostics)
671      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
672    
673    checkpoint57c_post
674    o Change testing option (-ieee) to get closer agreement between g77 & ifort
675    o generate new output.txt files on faulks with g77 & the new -ieee option
676    checkpoint57c_pre
677    
678    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
679      update output.txt of exp. global_ocean.90x40x15
680    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
681      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
682    o add saltFlux(+File) forcing capability with periodicExternalForcing
683    o allow to use pkg diagnostics for GM-Redi & ThSIce output
684    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
685    o improvements for the MNC output from DIAGNOSTICS:
686      - correct handling of the unlimitied dimension
687      - all dims now have associated coordinate variables
688      - variables located at U, V, and Corner ("Z") points are now written
689        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
690        *all* data points are output
691    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
692    o added pkg/seaice/seaice_monitor.F
693    o mdsio_readfield.F can now read files visible only to master MPI process.
694    o pkg/seaice: some test code for ice-modified ocean stress
695    o exf_getffields interpolation defaults to bilinear for all scalar forcing
696      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
697      spurious negative numbers for precipitation and humidity.  Will cause
698      some small numerical differences for integrations using pkg/exf/exf_interp.F.
699    o pkg/ctrl/
700      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
701        May be enabled via doPackDiag
702      *  introduce z-scaling of
703         + gradient (doZscalePack) and
704         + control (doZscaleUnpack)
705    o pkg/mdsio/
706      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
707      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
708    
709    checkpoint57b_post
710    o simplify options in diagnostics_fill arguments (remove weird combinations)
711    o fix MNC coordinate variables so that they now contain per-face index
712      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
713      general, EXCH2 grids are only aligned to a "local" coordinate system
714    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
715    o Implement instantaneous output within pkg diagnostics:
716      setting a negative frequency in data.diagnostics produces
717     "snap-shot" output (as opposed to time-average if freq > 0)
718    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
719      NOTE: change ptracer diagnostics name: use 2 characters to work with
720            more than 9 tracers. Add also diagnostics of advect & diffus flux.
721    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
722      becomes the coordinate variable for the 'T' dimension
723    o add CF-style coordinate variables to MNC
724      - just a first cut:  numbers are meaningless on the cubesphere and
725        missing along the T axis but otherwise it works!
726    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
727    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
728    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
729      this is based directly on what the model compute, so that the content of
730      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
731    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
732    o clean up build options files for SunOS, in particular
733      - remove -traditional from xmakedepend
734      - change -xarch=v9 to -xarch=native for f77
735      - restore use of make (not gmake)
736      - add CC=gcc if using g77
737    o changes per discussion of AM, JMC, & EH3 today:
738      - move redundant "grid" variables out of "state" -- in preparation of
739        creating proper CF-style coordinate variables and in recognition
740        that any/all grid variables can be easily copied (eg. w/NCO) from
741        the grid files into any of the other NetCDF files
742      - *always* output grid variables with MDSIO (this will eventually be
743        changed)
744      - output MNC grid file if useMNC is true
745    o every instance of _END_MASTER() has been found and replaced with
746      _END_MASTER( myThid ) in order to satisfy certain picky Sun
747      preprocessors
748    o re-arrange diagnostics pkg initialisation:
749     - allow each package to extend the available diagnostics list
750     - add some checking and fix small problems (multi-threaded, ...)
751     - new S/R diagnostics_fill (replace fill_diagnostics):
752       look through the short list of active diag. (instead of the long list)
753       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
754    
755    checkpoint57a_post
756    o this set of changes restores TAMC compatibility
757      tested for global_ocean.90x40x15 adjoint on trough
758      (what a pain)
759    
760    checkpoint57a_pre
761    o some modifs in tools/build_options for sunos
762    o call ctrl_pack for ctrl at end for optimcycle=0
763    
764    checkpoint57
765    o add horizontal bi-harmonic viscosity for vertical velocity
766      - new parameter viscA4W (defaults to viscA4)
767      - affects only non-hydrostatic code
768      - to be done: no-slip lateral boundary conditions
769    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
770    o implement Implicit Vertical advection for pTracers
771    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
772      (implemented also for implicit vertical diffusion & advection)
773    o OBCS: extend application of tracer open boundary conditions
774      to a strip beyond the boundary of width Olx/Oly
775    o add call monitor to TAF set of required calls (flow directives)
776      and include in natl_box_adjoint
777    o untangle a few ifdefs related to cost, ctrl, autodiff
778      untangel a few ALLOW_ECCO_OPTIMIZATION
779    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
780      (theta2, salt2 in ecco_cost_weights)
781    
782    checkpoint56c_post
783    o OBCS as control variables
784      - update ctrl_ad_diff.list, obcs_ad_diff.list
785      - remove balance of obcs controls from default
786      - fix index bug nobcs in ctrl_init
787      - fix dummy fields filen in ctrl_pack
788      - add dummy weights for obcs
789    o lsopt: comment out fort.94 output
790    o optim:
791      - remove unnecessary header files
792      - adjusted namelists
793      - add xerbla.F to Makefile
794    o exf:
795      - multiple modifications of exf_check_range
796      - unit change in exf_init_runoff from [m/year] to [m/s]
797    o mdsio:
798      - i/o-vector change debugLevel from debLevA to debLevB
799    
800    checkpoint56b_post
801    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
802      is called from DO_THE_MODEL_IO
803      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
804      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
805      - clean up PTRACERS_WRITE_TIMEAVE a little
806    o add another verification experiment that tests both the cfc-pkg and
807      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
808      reactive tendencies treated inline with regular timestepping
809    o testreport previously did a lousy job of comparing small numbers, so
810      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
811      implemented in the little c-progam tmp_cmpnum.c which is embedded in
812      testreport.
813    o ptracers_monitor: bug fix for MPI
814    
815    checkpoint56a_post
816    o GCHEM: finish reorganizating the package
817      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
818        (introduces another 3D-array for each passive tracer, but only if
819        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
820        gchemTendency is not needed because the timestep is done separately)
821      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
822      - GCHEM is now---more or less cleanly---separate from PTRACERS
823      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
824        so clear to me how that should be done in a general way.
825    o CFC: improve formatting of output in CFC_ATMOS
826    o PTRACERS:
827      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
828        that ALL experiments with ptracers enable can be checked. This makes
829        GCHEM_MONITOR obsolete.
830      - include a runtime parameter PTRACERS_monitorFreq that defaults to
831        monitorFreq
832      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
833    o add PTRACERS (PTR0[1-5]) to testreport output
834    o exf_check_range:
835      * default changed to .TRUE.
836      * will check values for niter0 if debLevA, every timestep if debLevB
837      * STOP in exf_check_range if 'out of range'
838      * range chosen generous to allow for potential extema
839      TBD: a version with stricter range
840           permitted range would be runtime parameters
841    o GMredi:
842      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
843      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
844      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
845    o GCHEM:
846      - move call to GCHEM_FORCING_SEP, so that it is now called before
847        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
848      - introduced a useGCHEM runtime flag and applied it everywhere.
849      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
850        this flag is now only visible within GCHEM-pkg routines.
851      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
852        be replaced by a 3D array that is computed before thermodynamics; for
853        this, the tracer ID iTracer had to be included into the parameter list
854        of ptracers_forcing
855      - set up forward_step to call gchem_forcing, that will replace
856        gchem_forcing_int in ptracers_forcing
857      - cleaning up
858    o small cleaning of exch2: remove files that are also in eesupp/src
859    
860    checkpoint56
861    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
862    o mnc: cleanup "full" files--fixes out-of-memory problem
863    o ECCO-GODAE
864      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
865      * fully merged and updated from SIO code
866        windstress sign change affects
867        - exf_inscal_[u/v]stress
868        - sign of xx_tau[u/v] adjustments
869        - signs in cost_scat
870      * ctrl_get_gen: avoid update of tau[u/v] for first few days
871      * natl_box_adjoint updated and compressed
872      * 2-level checkpoint switch added
873        (tested in EXP. 1 of natl_box_adjoint)
874      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
875    o SVD
876      * first complete, non-hacked version for SVD calculations
877      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
878        performed via direct access files admtlm_vector.it????
879        (via ctrl_[un]pack)
880      * optimcycle is used for ARPACK iteration counter
881        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
882      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
883        and add linear transforms where necessary
884      * controls are initial/final SST, SSS (can be extended; need to check
885        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
886    o mdsio: filename info to both stderr, stdout
887    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
888      from sign change
889    
890    checkpoint55j_post
891    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
892      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
893    o add consistent build directories and .cvsignore files to verification
894    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
895    o make all subroutines 30 or less characters in length for certain older
896      compilers to work (a thorough search only turns up two routines in
897      pkg/ptracers)
898    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
899      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
900    
901    checkpoint55i_post
902    o change arrays for total vertical diffusivity (2.D if explicit,
903      3.D if implicit) ; each ptracer uses its own background value.
904    o added mnc/NetCDF output capability to ocn_compon_interf
905      - added bits to verification/cpl_aim+ocn so that it can run on
906        ITRDA and other clusters without the mpirun "-wd" option
907    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
908      configuration
909    o give MNC the ability to create additional files rather than
910      exceeding a specified file size limit "MNC_MAX_FILESIZE"
911      - the default is just less than 2GB which is a practical limit
912        on many systems
913    o Compute the non-local term using either KPP vertical diffusivity (=default)
914       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
915    
916    checkpoint55h_post
917    o add verification test "vermix"
918    o remove all the *_ioinc flags and replace with the single global
919      outputTypesInclusive flag
920    o allow to set a vertical profile of vertical diffusivity for T & S
921    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
922    o useMNC moved from data.mnc to data.pkg
923    
924    checkpoint55g_post
925    o Renaming carbon AD experiments to comply with testreport conventions
926    o Updating adjoint of Held-Suarez hs94.1x64x5
927    o Fixing directives for non-ECCO forward_step, after ECCO directives
928      have been fixed to avoid recomp. of do_oceanic_phys
929      Works well for global_ocean.90x40x15,
930      but recomp. issue remains for carbon
931    o Updating adjoint output for natl_box_adjoint after
932      pkg/ecco has been modified (see taga c55d_post)
933    
934    checkpoint55f_post
935    o rename to timeave_init_fixed
936    
937    checkpoint55e_post
938    o some delicate re-shuffle of store directives to avoid one
939      extra call of do_oceanic_physics
940      affects ecco_the_main_loop.F, do_oceanic_physics.F
941      checkpoint_lev1_directives.h
942    o NB: this may break global_ocean adjoint temporarily,
943      but it is clear how to fix it. Will do later, need this now.
944    
945    checkpoint55d_post
946    o ECCO specific cost function terms (up-to-date with 1x1 runs)
947    o ecco_cost_weights is modified to 1x1 runs
948    o modifs to allow observations to be read in as
949      single file or yearly files
950    o enable to read exf forcing fields as either
951      single file or yearly files (flag useExfYearlyFields)
952    checkpoint55d_pre
953    
954    o switch between 2-level and 3-level checkpointing
955    o add ability of MNC to write local and "partial" (eg. 2D slices where
956      the full 3D field is never actually stored) arrays to NetCDF files
957      with the correct (that is, the complete multi-dimensional) set of
958      array indicies
959      - used in mom_vecinv() to write the diagFreq output
960      - tested (demonstrated) in verification/aim.5l_cs
961    o further mnc-ification
962      - add verification/lab_sea to the list with mnc setups
963      - fix undefined mnc v-names in cd_code
964      - add kpp to mnc output (both snapshot and timeave)
965    o non-hydrostatic code
966      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
967        in calc_gw.F
968      - defaults to viscAh
969      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
970        friction or Leith) in non-hydrostatic mode, as long as there is
971        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
972    o pkg/cost
973      extend simple cost functions to treat time mean quantities
974      (T,U,V) via cost_accumulate_state from cost_tile
975    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
976        be 2 times larger than the minimum size the advection scheme requires.
977        now get a perfect conservation of salt in advect_cs test-exp (updated)
978    o GGL90 (Gaspar's TKE mixed layer)
979      - add horizontal diffusion of TKE, requires exchanges in
980        do_fields_blocking_exchanges, horizontal diffusivity is zero by
981        default. In OPA there is no horizontal diffusion of TKE but the
982        mixing coefficients are computed from a horizontal average of TKE of
983        6 points or so. I think that diffusion has a little more physical
984        justification.
985      - clean up ggl90_calc in the hope of reducing memory usage (this hope
986        was in vain)
987      - mask tke-variable in ggl90_init
988    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
989    o fix biharmonic diffusion on CS-grid.
990    o more obcs stuff
991      - added obcs_external_fields_load as an alternative to the EXF-pkg option
992        for reading boundary values. This routine is called from
993        obcs_prescribe_read
994      - updated obcs_check
995      - changed sponge layer relaxation parameter units for days to seconds
996      - turned off sponge layer by default
997      - changed argument list of OBCS_CALC to myTime+deltaTclock
998      - fixed about 35 bugs in obcs_external_fields_load
999    
1000    checkpoint55c_post
1001    o obcs stuff
1002      - new runtime flags useOBCSprescribe, useOBCSbalance
1003      - re-arranged obcs_calc
1004      - moved exf_getobcs to obcs_prescibe_read
1005        obcs_prescibe_read is called after ORLANSKI stuff
1006        and independent of it (executable can contain all).
1007      - updated obcs_check
1008      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1009        These may be necessary only if tangential velocities are
1010        prescribed at OB, not sure, needs testing.
1011    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1012      which simplifies the calls and passes the ifc check-bounds test
1013    
1014    checkpoint55b_post
1015    o add a 2D scalar, Z location, exchange_2 routine.
1016    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1017      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1018      affects advect_cs results (for the wrong reason): update output.txt
1019    o use a more standard discretization for biharmonic viscosity ;
1020     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1021      affects results of dome set-up: update output.txt
1022    o fix gad_advection.F (CubedSphere part), back to version 1.23
1023    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1024    
1025    checkpoint55a_post
1026    o merged code to
1027      * prescribe/read time-dependent open boundaries
1028        (works in conjunction with exf, cal)
1029      * sponge layer code for open boundaries
1030      * each boundary N/S/E/W now has its own CPP option
1031        (healthy for the adjoint)
1032    
1033    checkpoint55
1034    o up-to-date adjoint of previous breaks
1035      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1036      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1037      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1038      - carbon: * remove tr1-related adjoint verification
1039                * add ptracer as control variable
1040    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1041      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1042    
1043    checkpoint54f_post
1044    o in verification/carbin/ remove experiment related to
1045      ALLOW_PASSIVE_TRACER (array tr1 etc)
1046      code_ad/ input_ad/ results_ad
1047    
1048    o add two new packages
1049      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1050        + subject to optimization (memory)
1051      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1052        + subject to reordering (many GOTOs in the original code)
1053        + so far opps is called for every (i,j) point, and then operates in
1054          the vertical; one may want to reorder the scheme in order operate in
1055          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1056          fields)
1057    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1058      - all verification tests compile and run with linux_ia32_g77
1059      - defaults are compatible with current input files--nothing
1060        should change if you were not previously using MNC
1061      - MNC output has been added in numerous places (eg. timeave)
1062        but there are still a few writes not yet do-able with MNC
1063        (this is in progress)
1064      - flags now allow for either/or/both use of MDSIO and MNC and
1065        documentation will soon follow
1066      - numerous small formatting cleanups for ProTeX
1067    o add version info (via BUILD_INFO.h) to MNC and stdout
1068    
1069    checkpoint54e_post
1070    o add two new packages
1071      - pp81 (Packanowski and Philander, 1981), Richardson number and
1072        stratification dependent mixing
1073      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1074      - these scheme operate in a similar manner as KPP (without ghat, of
1075        course), however there is only one diffusivity that is used for both
1076        temperature and salinity (and passive tracers)ç
1077    o add offline package
1078    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1079      provided by Stephanie Dutkiewicz
1080    o genmake2: add ability to search for C compilers and cleanup test output
1081      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1082    
1083    checkpoint54d_post
1084    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1085    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1086      leading to additional shift by 5 days each year of integration
1087       (i.e. leading to considerable offset over the years)
1088    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1089    o start with no AB and no initial filtering (staggerTimeStep):
1090      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1091    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1092      (external loading & cpl import/export stay in forward_step.F)
1093    o update coupling interface to work with new staggerTimeStep
1094    o change MDSIO ptracers_pickup.
1095    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1096    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1097    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1098    
1099    checkpoint54c_post
1100    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1101      this affects (truncation error) output.txt of test-exp:
1102       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1103    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1104    o change Qnet to always be the net heat flux, (+upward).
1105      affects (truncation error) output of natl_box exp.: updated
1106    o define the max number of passive tracers in PTRACERS_SIZE.h
1107    o start to test mnc routinely in exp0
1108    o add sea-ice loading (sIceLoad) as a new forcing field.
1109    
1110    checkpoint54b_post
1111    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1112       impressive on Altix and Opteron systems)
1113    o diagnostics can now write NetCDF files through the mnc package
1114    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1115    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1116    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1117      affects (truncation error) output of lab_sea & natl_box exp.: updated
1118    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1119    
1120    checkpoint54a_post
1121    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1122    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1123    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1124    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1125      + internal_wave (shift in writing cg2d_ini_res)
1126    checkpoint54a_pre
1127    
1128    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1129      - modified verification/lab_sea and natl_box_adjoint accordingly
1130    
1131    checkpoint54
1132    checkpoint53g_post
1133    o prepare splitting of thermodynamics: store convect.counter in common block
1134    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1135      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1136    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1137    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1138    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1139    o restore adjointability
1140    
1141    checkpoint53f_post
1142    o modifications that affect AIM experiment results (update output.txt):
1143      - no advection of S at top interface Nr (pkg/generic_advdiff)
1144      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1145    o AIM pkg:
1146      - include stability function into surf.Flux derivative relative to Tsurf
1147      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1148    
1149    checkpoint53e_post
1150    o merged cylindrical coord configuration
1151    o added rotating_tank experiment
1152    checkpoint53e_pre
1153    
1154    checkpoint53d_post
1155    o faulks upgraded: re-generate output.txt that have changed:
1156       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1157    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1158    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1159    o added Sadourny discretization of Coriolis
1160      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1161      - re-enabled use of omega3 (useAbsVorticity)
1162    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1163      vector-invariant equations
1164      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1165    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1166      hopefully without new bugs
1167      - still to do: biharmonic friction for non-hydrostatic w
1168    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1169    o regenerated output for global_ocean_ebm (using -ieee)
1170    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1171      of mom_common/
1172      - simple re-arrangement of instructions within computing loop
1173    checkpoint53d_pre
1174    
1175    checkpoint53c_post
1176    o new version of coupler for AIM+thSIce and Ocean models
1177     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1178     - land: change Evaporation of snow
1179     - aim with thSIce: fix bug in snow-precip.
1180    o changes to calc_gw.F
1181     - bug fix for w^2 term near the bottom boundary
1182     - (hopefully) improve the lateral slip boundary condtions for use with
1183        partial/looped cells
1184      - because the bug fix changes two verification experiments anyway (exp5
1185        and plume on slope), change the lateral boundary condition from half slip
1186        to the value of no_slip_sides
1187    o ebm package wasnt quite up to the parallel task. Fixed that.
1188    o Adjoint of EBM package + verification
1189      * TLM OK
1190      * ADM not sufficient accuracy yet (needs further testing)
1191    
1192    checkpoint53b_post
1193    o Commiting new energy balance model to repository
1194      * package is pkg/ebm
1195      * verif. is verification/global_ocean_ebm
1196      * references are in ebm_driver.F
1197    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1198    C        Global thermohaline circulation. Part I:
1199    C        Sensitivity to atmospheric moisture transport.
1200    C        J. Climate 12(1), 71-82
1201    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1202    C        Global thermohaline circulation. Part II:
1203    C        Sensitivity with interactive transport.
1204    C        J. Climate 12(1), 83-91
1205    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1206    C        Destabilization of the thermohaline circulation
1207    C        by atmospheric eddy transports.
1208    C        J. Climate 7(12), 1870-1882
1209    o Will need long integration testing.
1210    checkpoint53b_pre
1211    
1212    o created pkg/mom_common in preparation for variable viscosity code
1213    o renamed and split ini_mnc_io
1214    o pkg/land: only liquid water can diffuse or run-off
1215    o AIM using land: soil wetness availability account for snow
1216    o added printMapIncludesZeros to EEPARMS namelist
1217    
1218    checkpoint53a_post
1219    o restore TAMC compatiility for exf_constants.h
1220      (no usage of _d in .h)
1221    o Additional storing in KPP in an attempt to fix
1222      TAMC problem with adjoint of KPP code.
1223      (no success...)
1224      Identical code works fine with TAF.
1225    o Fixed verification/natl_box_adjoint experiments.
1226      Initial conditions for Experiments 4 and 5 are now
1227      set to "SEAICE_initialHEFF=0", which is more reasonable,
1228      and hence gives results closer to that of Experiment 2.
1229      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1230    
1231    checkpoint53
1232    o stable checkpoint with up to date adjoint
1233      TLM tests only run for 1st grdchk at the moment. Its unclear if
1234      this is a code problem or a problem with resetting code for g_
1235      variables that is being autogenerated wrong.
1236      Otherwise:
1237       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1238       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1239         are both still in chaos following their security messes.
1240    
1241    checkpoint52n_post
1242    o various build (mostly genmake2) changes including:
1243      - ability to build/run more easily within Cygwin and MacOS X
1244      - more complicated Makefiles with a stronger dependence on Gnu Make
1245    o pkg/seaice modifications
1246      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1247        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1248        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1249      - changed proxy for geostrophic velocity and updated
1250        verification/lab_sea/results/* accordingly
1251      - removed ADI dynamic solver from pkg/seaice
1252      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1253        they caused a segmentation fault under certain circumstances
1254      - removed unused field WATR
1255    o bug fix in exf-package:
1256      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1257         now reflect that.
1258    o small fixes in the cal-package:
1259      - set reference date to first of January for the 'model'-calendar
1260      - failing of cal_CheckDate in cal_FullDate now actually results in a
1261        warning
1262    o small modifications in exf-package to increase flexibility:
1263      - change climtempfreeze from a constant to a runtime parameter that
1264        is specified in data.exf_clim (default = -1.9)
1265      - introduce runtime parameter windstressmax (default = 2.0) that is
1266        specified in data.exf
1267    o fix in pkg/thsice:
1268      - update Evap (Tsf changes) to be consistent with Latent heat flux
1269      - maintain snow precipitation unchanged (even if Tsf >=0).
1270     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1271    
1272    checkpoint52m_post
1273    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1274      this does not change any of the results, because myIter=0 in swfrac always
1275      lead to jwtype=2 (the default anyway), but the call makes little sense
1276      as a default
1277    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1278    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1279      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1280    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1281    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1282    o extending useSingleCpuIO option to work with new exch2 I/O format
1283      - old-style, missing-tile I/O is still accessible by defining CPP
1284        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1285    o monitor package can write to NetCDF files and/or STDOUT
1286    o fix re-definition bug in MNC_GRID_INIT_ALL()
1287    o doc/api_reference added
1288      - a framework for building an API Reference Manual using all
1289        the "protex" comments embedded in the code
1290      - see pkg/generic_advdiff, pkg/mnc for examples
1291    o MNC:
1292      - make myThid the last argument for all subroutines
1293      - new default for the grid files: NO halos
1294      - add useMNC and other run-time flags
1295      - separate per-file-group handling of the unlimited dimension
1296      - early initialization of MNC w/ flags read at the eeboot stage
1297        and lookup tables set in initialize_fixed
1298      - write all MNC output to a freshly-created directory
1299    o thermodynamics sea-ice (thsice) is now tested with testreport.
1300    o test exp. advect_cs: use the standard cs32 grid ; update output.
1301    o Added functionality to grdchk:
1302      pick global i,j,k position (or nearest wet) where to perform check.
1303    
1304    checkpoint52l_post
1305    o new land formulation:
1306      a) use ground enthalpy as prognostic variable to ensure exact
1307         energy conservation.
1308      b) account for water temperature and for latent heat of freezing
1309         in all processes (rain, run-off, ground storage)
1310      c) compute surface and ground temperature implicitly.
1311    o aim_v23 modification for new land model:
1312      a) Treat separately land / ocean / sea-ice surface fluxes
1313         to allow implicit computation of land & sea-ice surface temp.
1314      b) add snow precipitation.
1315    checkpoint52l_pre
1316    
1317    o fix problem (when 1 tile is empty) in min/max monitor.
1318    o fix bug in timeAve (u,vZetatave in common block)
1319    o no restoring terms under ice for pkg/seaice
1320    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1321    o bug fix for pkg/seaice pickups
1322    o change MNC call locations and add coordinate attributes
1323    o mask vorticity at the corner ; affects global_ocean.cs output
1324    o fix ini_curvilinear_grid ; test CS experiments with mpi
1325    o aim.5l_cs: modify sea-ice fraction input file ; update output
1326    o exf: Adding simple range check routine for exf fields after read
1327    
1328    checkpoint52k_post
1329    o removed top-level directory "diags"
1330      - we migrated these functions to pkg/timeave a long time ago
1331    o fixed bug introduced in pkg/monitor
1332    o accuracy ctrlprec = 32 insuffient for gradient checks using
1333      averaged fields (I/O via cost_averages)
1334      -> use ctrl.h in active_file*.F to control I/O precision.
1335    o paramter list of CALL ADTHE_MAIN_LOOP
1336    o added initial do_the_model_io to ecco
1337    o set all ...Freq to zero after cost_final
1338      taveFreq, dumpFreq, pChkptFreq
1339    o MAIN and ECCO differentiability restored
1340    
1341    checkpoint52j_post
1342    o fix nchklev in tamc.h for global_ocean...
1343    o Bringing flow and store directives up-to-date
1344    o Really weird thing!
1345      call do_the_model_io from the_main_loop with parameters
1346      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1347      TAF places a faulty re-call of initialise_varia
1348      after cost_final call which should not be there!
1349    checkpoint52j_pre
1350    
1351    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1352      error messages
1353    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1354    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1355      debug output
1356    o modfied mdsio_writefield.F to handle non-global files under exch2
1357    o update AIM Cubed-Sphere exp (aim.5l_cs):
1358      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1359    o update AIM Equatorial Channel exp:
1360      use standard aim_v23 pkg and change the SST fields to be more realistic.
1361    o globalFile now works with exch2
1362    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1363      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1364    o limit timeave output for hi-res integrations
1365    
1366    checkpoint52i_post
1367    o removed CPP_EEOPTIONS.h from verification/*/code
1368    o updated the tiling for global_ocean_pressure
1369    checkpoint52i_pre
1370    
1371    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1372      the old pkg/aim).
1373    
1374    checkpoint52h_pre
1375    o shortened offending lines in exch2_send_rx?.template
1376    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1377    o genmake2: add build & execute test for NetCDF code
1378    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1379      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1380    o added useSingleCPUIO flag to monitor.F and mon_out.F
1381    o added temporary hack for sea-ice dynamics on the cube:
1382      metric terms are ignored and it is assumed that
1383      there is no sea-ice on cube faces 1, 2, 4, and 5.
1384    
1385    checkpoint52f_post
1386    o added exch2 cube routines to pkg/exch2
1387    o modified hs94.cs-32x32x5 to use it
1388    o added new grid files to hs94.cs-32x32x5
1389    checkpoint52f_pre
1390    
1391    checkpoint52e_post
1392    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1393      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1394    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1395      to work with implicit vertical advection and AB ;
1396    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1397    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1398     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1399    checkpoint52e_pre
1400    
1401    o fix bug in impldiff when Nr=1 or Nr=2.
1402    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1403    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1404    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1405      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1406    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1407    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1408    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1409    
1410    checkpoint52d_post
1411    o re-tiled many expts to allow comparison in multi-processor mode
1412      - updated output accordingly
1413      - changed hs94.128x64x5 to use intial T from file rather than use the
1414        random number generator
1415    o add infrastructure in model routines for fizhi and gridalt packages
1416    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1417    o changes to permit hi-res, cubed-sphere, configuration
1418      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1419      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1420      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1421        of surface winds for the cube
1422      (A verification experiment, based on global_ocean.cs32x15, but with
1423       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1424       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1425       complete with example surface forcing files and matlab scripts to look
1426       at the output and compare it with that of global_ocean.cs32x15.)
1427    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1428       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1429       to conform to the common rule.
1430    o check-in the first version of the coupler + interfaces for multi-components
1431       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1432       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1433       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1434       - ocean and atmos. share the same horizontal grid (no interpolation).
1435       - exchanges between component and coupler is done in forward_step
1436    o new verification experiment, cpl_aim+ocn:
1437       coupled ocean - AIM atmosphere on cs32 grid.
1438    
1439    checkpoint52d_pre
1440    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1441    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1442    
1443    checkpoint52c_post
1444    o Fixing OPTIONS files for use of exf:
1445      - ALLOW_ECCO not needed
1446      - ECCO_CPPOPTIONS.h should not be included from
1447        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1448        as has been the case in the past
1449      - All cal/exf related options are currently set in
1450        single header file. Should remain so until we
1451        agree on a consistent new policy.
1452    o Removed all CPP options for cal package.
1453      cal has no more CPP options.
1454    o modified STOREs in GAD_ADVECTION
1455    o corrected key comp. for passkey
1456    
1457    checkpoint52b_post
1458    o new version: "thsice" of thermodynamic sea-ice pkg:
1459     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1460     - modify fluxes but do not change theta directly;
1461     - light cleaning of bulk_force pkg (still needed with thsice).
1462     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1463       + output_thsice.txt to test thsice & bulk_force pkgs.
1464    o put back grid & coriolis monitor output.
1465    checkpoint52b_pre
1466    
1467    o call "do_the_model_io" at the beginning (=> dump initial state)
1468    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1469    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1470      (need info on NUMBER_OF_PTRACERS)
1471    o missing PTRACERS headers in some routines
1472    o default tamc.h in pkg/autodiff supposed to crash
1473      to ensure proper customization
1474    
1475    checkpoint52a_post
1476    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1477      - moved surfaceTendencyTice from pkg/seaice to main code
1478      - subroutine FREEZE_SURFACE now limits only surface temperature
1479        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1480        => new output.txt for global_ocean.cs32x15 & global_with_exf
1481      - keep the old version of FREEZE for backward compatibility;
1482        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1483      - corresponding modifs for TAF directives
1484    o added surface flux output variables to TIMEAVE_STATVARS
1485    o time-averaged output for pkg/ptracers
1486    o fix problem with ECCO-related divided adjoint
1487      snapshot file was missing some ad-variables,
1488      but no warning issued by TAF
1489    
1490    checkpoint52a_pre
1491    o some bug fixes for #undef REAL4_IS_SLOW
1492    
1493    checkpoint52 = ecco_c52_e35
1494    o after testing adjoints of checkpoint51u_post
1495    
1496    checkpoint51u_post
1497    o this is the post-merge tag of the ecco-branch
1498      (needs another clean checkout and re-testing)
1499    o various natl_box_adjoint configs and results
1500      but no input fields
1501    o obcs adjoint not yet merged!
1502    o adding ECCO global 1x1 and 2x2 degree configs
1503    o updated/extended some store directives for seaice
1504    o pkg/ecco now containes ecco-specific part of cost function
1505    o top level routines the_main_loop, forward_step
1506      supersede those in model/src/
1507      previous input data.cost now in data.ecco
1508      (new namelist ecco_cost_nml)
1509    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1510    
1511    checkpoint51t_post
1512    o this is the pre-merge tag of the ecco-branch
1513    
1514    checkpoint51s_post
1515    o cleanup: removed various obsolete #define-s
1516    o pkg/grdchk
1517      - renamed 'ph-grd 3' to 'grad-res'
1518      - merged from ecco-branch
1519        (remaining bug fixes for obcs gradient checks)
1520      - additional high-precision output for testreport
1521        (grep for 'precision_grdchk_result')
1522    
1523    checkpoint51r_post
1524    o cleaned up or removed CPP_OPTIONS.h files
1525    o updated results for some of the tests to reflect the new
1526      optfiles (-ieee: -O0 instead of -O3)
1527    
1528    checkpoint51q_post
1529    o cd_code:
1530      - moved cd_scheme.F -> cd_code_scheme.F
1531      - separate read_checkpoint from cd_code_ini_vars.F
1532      - separated cd_code part from write_checkpoint
1533      - updated AD_SOURCE, generated .flow
1534      - added CD_CODE_VARS.h to the_main_loop
1535      - Moving cd_code specific store dir.s to pkg/cd_code
1536    o ctrl package totally restructured
1537      - pack/unpack now optional and decoupled from
1538        xx_/adxx_ I/O
1539      - ctrl_pack/unpack cleaned
1540        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1541      - confined inclusion of AD_CONFIG.h to where necessary.
1542    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1543    
1544    checkpoint51p_post
1545    o create initial cd_code package
1546      - WARNING: the initialization of fields within packages
1547        is broken because INI_FIELDS (where READ_CHECKPOINT is
1548        called) is called *before* PACKAGES_INIT_VARIABLES.
1549        This seems to be backwards since
1550        1) its important to initially zero the entire field including
1551           the "halo" region
1552        2) zeroing needs to be done *before* reading pickup info
1553           and the pickup call might or might not happen in any
1554           particular run
1555      - this needs an overhaul for R2
1556    o cleanup verification/*/code/GMREDI_OPTIONS.h
1557    o cleanup testreport
1558    
1559    checkpoint51o_post
1560    o bringing AD-related verif's up to date with genmake2
1561      - carbon/
1562      - global_ocean.90x40x15/
1563      - hs.94.1x64x5/
1564      - (front_relax/ )
1565    o (more) consistent directory structure for AD-related verif.'s
1566    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1567    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1568    o bug fix in find_alpha.F for MDJWF:
1569      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1570        change rho -> rho-rhoConst
1571      - replace call find_rho to find_rhonum
1572    o initialisation of rFlx extended to full array (required by TAF)
1573      and shifted to thermodynamics
1574    o removed PTRACERS.h in ptracers routine
1575    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1576    o Correcting initialisations for fVerU, fVerV.
1577    o helping TAF to recognize dependency on kUp for
1578      fVerU, fVerV
1579    o Replacing delZ by delR in pkg/ctrl/
1580    checkpoint51o_pre
1581    
1582    o undid all of cp51 pending some cleanups and discussion
1583    o added the [#include "AD_CONFIG.h"] statement to all files that need
1584       it for adjoint/tl #defines
1585     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1586     o removed tools/genmake since it no longer works
1587    
1588    checkpoint51n_post
1589    o modifications to make FREEZE flux visible to pkg/kpp
1590      - moved surfaceTendencyTice from pkg/seaice to main code
1591      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1592      - subroutine FREEZE now limits only surface temperature
1593        (this means new output.txt for global_ocean.90x40x15,
1594         global_ocean.cs32x15, and global_with_exf)
1595    o added surface flux output variables to TIMEAVE_STATVARS
1596    
1597    checkpoint51n_pre
1598  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
1599  o added [#include "AD_CONFIG.h"] to all files that use the following  o added [#include "AD_CONFIG.h"] to all files that use the following
