5      ==============================      ==============================
6    
7    o Initial check-in of lab_sea adjoint
8      (very similar to natl_box_adjoint/code_seaice)
9      * used C-grid and EVP solver
10      * used KPP, GM/Redi
11      * uses inAdExact=.TRUE.
12      * gradient checks fail for both ADM and TLM
13        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
14        f.d. gradients actually seem more problematic than ADM, TLM gradients;
15        issue is related to forward mismatch between g77 an ifort
16    o pkg/seaice: overhaul of thermodynamics
17     - growth.F and groatb.F are replaced by new routine seaice_growth.F
18     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
19     - move a few global fields out of SEAICE.h into seaice_growth.F and
20       make them 2D (FICE/QNETO/ ...)
21     - remove FO (it is the same as QNETO)
22     - introduce a few local fields to avoid modifying external fields such
23       as atemp, etc.
24    
25    checkpoint58s_post
26    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
27      changed exf_set_gen.F so that
28        genperiod=0 means input file is one time-constant field and
29        genperiod=-12 means input file contains 12 monthly means
30    o CG2D: use pre-computed solver main-diagonal (stored in common block);
31      this affects truncation error ; generate new output file for exp. which
32      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
33        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
34        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
35        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
36        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
37        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
38    o start implementation of deep-atmosphere and anelastic formulation
39    o verification: remove 2nd copy of input files and use script "prepare_run"
40      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
41    o mom_common/vecinv/fluxform: fix a few initialisation isssues
42    o profiles: fix for multithreaded case
43    
44    o diagnostics: rename few diags:
45      s/'PRESSURE'/'RCENTER '/g
46      s/'TICE    '/'oceFreez'/g
47      s/'TAUX    '/'oceTAUX '/g
48      s/'TAUY    '/'oceTAUY '/g
49      s/'SWFLUX  '/'oceQsw  '/g
50      s/DIFx/DFxE/g
51      s/DIFy/DFyE/g
52      and add few ocean-forcing diagnostics:
53      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
54    o modifications to pkg/seaice/growth.F and budget.F, which change results of
55      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
56      as actual snow thickness.  It now refers everywhere to effective snow
57      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
58    
59    checkpoint58r_post
60    o modifications to pkg/seaice/growth.F, which change results of
61      lab_sea experiment: fixes pertain to melting snow over open water, to
62      masking EVAP under sea ice, and to using the correct AREA variable for
63      computations of EVAP, PRECIP, HSNOW, and GHEFF
64    o add ability to read bathy, salt, and theta using MNC (off by def)
65    o add flooding algorithm and advection of HSNOW for pkg/seaice;
66      both are turned off by default and do no change any results
67    o seaice advection with pkg/thsice: a step toward the use of non-linear
68      advection scheme, but #ifdef or commented out for now (requires more EXCH).
69    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
70      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
71      in natl_box (affects results @ truncation level: update output.txt)
72    o multi-threading and IO:
73      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
74      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
75        (needed to work with SingleCpuIO): tested in all verif. exp.
76    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
77      affects the results (but none of the verification test uses this scheme).
78    o Adding some pkg/diagnostics capability to pkg/seaice
79      (will certainly be subject to changes)
80    o ctrl: adding new control variables:
81      lwflux, lwdown, evap, snowprecip, apressure, runoff
82    
83    checkpoint58q_post
84    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
85      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
86      high_res_cube configuration by 4% on Columbia.
87    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
88      add (in global_with_exf/code) a version of EXF_INTERP_READ without
89      dynamical allocation (seems to work in multi-threaded).
90    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
91      single CPU io) so that TAF does not have to see EESUPPORT.h
92    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
93    
94    checkpoint58p_post
95    o obcs: stop if obcs is used with useCDscheme = .true.
96    o shelfice:
97     - fix a sign error so that no slip at shelfice interface works
98     - remove stop for combination non-hydrostatic code and shelfice. That does
99       not mean, that the results are correct, but at least they are numerically
100       stable
101    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
102    o added adjoint exch routined for all exch*3d* routines
103      and updated flow directives
104    
105    checkpoint58o_post
106    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
107      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
108    o change controling S/R for writing pickup file (new S/R do_write_pickup)
109      and clean-up reading/writing of pickup files.
110    o fix local version of read/write pickup (NH part) in rotating_tank/code
111    o simplify EXCH interface:
112     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
113     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
114    o added the regrid package
115    o shelfice:
116     - add a simple boundary layer scheme to reduce noise
117     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
118    
119    checkpoint58n_post
120    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
121       local variable (not in common block).
122    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
123      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
124      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
125        to work with SingleCpuIO.
126    o add "_d 0" to real constant of pkg/cfc subroutines ;
127       update exp. cfc_exemple & tutorial_cfc_offline output files.
128    o multi-threading and IO:
129      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
130        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
131      - barrier before and after reading.
132      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
133      - avoid using MDS_WRITELOCAL for LAND pkg output.
134      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
135        common-block variables ; Allows multi-threading with master-thread IO.
136    o change default MAX_NO_THREADS from 32 to 4 ;
137      and stop cleanly when MAX_NO_THREADS is too small.
138    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
139    
140    checkpoint58m_post
141    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
142       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
143    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
144       keep global_ocean.90x40x15 (for AD testing) with former secondary test
145       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
146    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
147        add MITgcm_tutorials (= code + all the tutorials)
148    o ecco, option to compute cost for total ssh (mean+anom)
149    o consistent with addition of ptracer and ssh in pkg/profiles
150    o profiles: adding ptracer and ssh
151    o testreport: change multi-test output-file name
152      (from output.txt.{name} to output.{name}.txt)
153    o profiles: now ok for mutli-tiles case
154    o seaice: add 4 parameters for different advection schemes for area,
155      (effective) seaice thickness, enthalphy, and snow height. Their default
156      is the standard parameter SEAICEadvScheme
157    o calc_gw:
158     - add cosFacU in zonal viscous flux (harmonic.visc.).
159     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
160       of tutorial_plume_on_slope.
161    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
162    o calc_gw: true flux-form, account for horizontal grid spacing.
163      update rotating_tank results, but not plume_on_slope (affected at
164      truncation level, 11 digits).
165    
166    checkpoint58l_post
167    o calc_gw:
168     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
169     - remove side-drag for now (need to fix it); update plume_on_slope results.
170     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
171    o commit code to make SST/SSS weights spatially variable
172      (based on either variable in-situ or variable initial T/S weights)
173    o pkg/ecco:
174      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
175        now based on horizontally varying weights wthetaLev, wsaltLev
176      * cost_averagesflags now returns year indices in addition to day, month
177      * sflux balance is performed on annual basis
178        (sflxumm, sfluxmm2, bal_sfluxmm)
179      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
180        including separate counting and multipliers
181    o pkg/rbcs
182      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
183    
184    checkpoint58k_post
185    o testreport:
186     - always build in dir. "build" (if not there, mkdir build instead of building
187       & running in input)
188     - run in dir run (if it exists), in build otherwise.
189     - call prepare_run (if input/prepare_run exists)
190     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
191    o pkg/exf modifications to interpolation and rotation routines for more
192       reasonable treatment of North Pole singularity: for tracers North Pole
193       value is set to northernmost zonal-mean value, for zonal velocity it is
194       set to zero, and for meridional velocity it is set to northernmost value.
195    o pkg/exf/exf_check_range.F
196     - add tile index to diagnostics and move stop statement to the very
197       end of the routine.
198    o pkg/diagnostics: (diagnostics_main_init.F)
199      define title of isomorphic variables according to the current config.
200    o pkg/thsice with pkg/seaice dynamics:
201    - fix domain of computation (interior only, required for exf) and do exchanges
202    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
203    o towards a standard way of dealing with multi-threading in MONITOR
204      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
205    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
206       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
207    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
208    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
209    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
210       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
211    o tracer advection:
212     - clean-up and simplify calc_common_factors.F
213     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
214       advection subroutine (but still not used within DST advection S/R)
215    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
216    
217    checkpoint58j_post
218    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
219      from file (collects calls previously in FORWARD_STEP)
220    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
221    o adjoint store dir. adjusted accordingly
222    o genmake2
223      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
224    
225    checkpoint58i_post
226    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
227      on wind stress (SEAICEstressFactor defaults to 1.)
228    o Total number of Timers is finite (<=40): comment out 2 non-essential one
229      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
230    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
231      on CS-grid: no longer loosing mass.
232    o exf & curvilinear-grid: no longer modify longitude xC & xG.
233    o pkg/ggl90: fix sloppy output and fix a bug
234    o pkg/seaice: added SEAICEuseEVPpickup parameter
235      - Set to false in order to start EVP solver with
236        non-EVP pickup files when using SEAICEuseEVP
237      - fix sign error in diffusion in seaice_calc_rhs
238    
239    checkpoint58h_post
240    * Modifications for bottom topography control
241      o replace hFacC by _hFacC at various places
242      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
243      o add non-self-adjoint cg2d_nsa
244      o update autodiff support routines
245      o re-initialise hfac after ctrl_depth_ini
246      o works for 5x5 box, doesnt work for global_ocean.90x40x15
247    * Adding verification for 5x5 box (4-layer) bottom topography control
248    
249    checkpoint58g_post
250    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
251       used for mean seasonal cycle, mean diurnal cycle); add an example
252       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
253    o pkg/ggl90:
254      - add parameter (minimum surface kinetic energy)
255      - fix bug (avoiding division by zero)
256    o couple pkg/thsice to pkg/seaice:
257      - modify advection in seaice to accomodate new scalar fields to be advected
258      - only muliDimAdection scheme work with seaice/thsice
259      - mapping of thsice-variables to seaice-variables, back and forth
260      - does not break the verification experiments, but does not give the
261        desired results either
262    o pkg/seaice
263      - make (default) second order advection a bit less confusing?
264    
265    checkpoint58f_post
266    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
267      to pkg/seaice):
268      - new routines thsice_map_exf and thsice_get_exf provide the interface
269      - add an additional formal parameter to thsice_solve4temp
270    o pkg/exf:
271      - add new fields wspeed, snowprecip (to be able to couple to thsice)
272      - correct Stefan-Boltzmann constant
273      - new parameter for longwave surface emittance
274      - separate some stuff from exf_bulkformulae into new routines  
275        exf_radiation, exf_wind
276      - add new parameters and constants: longwave emissivity for ocean, ice
277        and snow, evaporation parameters over ice
278      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
279        either wind from stress or stress from wind
280    o pkg/thSIce:
281    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
282    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
283       and THSICE_CALC_THICKN
284    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
285    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
286      to make debugging easier.
287    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
288    o pkg/bulk_force:
289      - clean-up comments and parameters ;
290      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
291    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
292      generate new output for test-experiment: aim.5l_cs.thSI
293    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
294      testreport accordingly
295    
296    checkpoint58e_post
297    o SEAICE_CGRID adjoint done
298    o R_STAR adjoint implemented.
299      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
300      * need to sort out init. of h0facc, etc.
301    o Make pkg/profile fully independent of ecco,cost, etc. stuff
302      to be able to use it in pure forward.
303    
304    checkpoint58d_post
305    o upgrade simple test-experiment to tutorial example:
306     step.1: duplicate the experiment and (step.2) will remove the old copy.
307      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
308      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
309      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
310      tutorial_global_oce_biogeo    <- copy of dic_example
311      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
312      tutorial_plume_on_slope       <- copy of plume_on_slope
313      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
314      tutorial_global_oce_optim     <- empty for now (David ?)
315      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
316     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
317    o correct a sign problem in cost_scat.F
318    o obcs and ptracers: fix boundary conditions for advections schemes
319      with larger stencil
320    o thsice adjoint: start
321    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
322      completeness
323    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
324      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
325    o ptracers adjoint:
326      * avoid extensive recomputatations
327      * fix missing re-init. of gptr (missed by TAF)
328    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
329      me to turn off the excessive output to STDOUT that this package produces
330    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
331      and add those terms in Vector-Invariant formulation.
332    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
333      if the control period (xx_hfluxperiod etc) is 0
334    o in profiles pkg, clean routines and fix details
335    o in ecco pkg, reading ssh data:
336      fix problem in case the model does not start at iter0=0
337    o fix mnc-pickup/restart for ptracers
338    o new package prifiles:
339      code to compute profile-based cost by Gael Forget
340      (modifs in ecco, ctrl, autodiff)
341    o Benign bug fix in initialization (spotted by M. Mazloff) of
342      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
343    
344    checkpoint58c_post
345    o adjoint: finish NLFS adjoint and provide reference output in
346      verification/global_ocean.90x40x15/results_ad_nlfs
347    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
348      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
349      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
350      with SEAICE_CGRID defined.
351    o move calendarDumps from "data" to "data.cal" and clean-up the code
352      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
353    o add useEXF & useCAL flags (for now, set in hard-coded way)
354    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
355      (were missing in NH mode, and wrong in quasihydrostatic mode).
356      waiting for Chris updated version of calc_gw to add those CALLs.
357    o fix bug in quasihydrostatic S/R ;
358      add a test for this option: global_ocean.90x40x15.qshyd
359    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
360      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
361    o add on/off flag useOffLine for package OFFLINE
362    o seaice:
363      - modify advection so that it works also on the C-grid
364      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
365        problem in multi-tile runs with C-grid
366      - add flags for clipping ice velocities and/or masking solver forcing
367      - fix drag (ocean on ice) formulation and a bug that caused noise in the
368        C-grid solver
369      - added a few comments to seaice_diffusion.F
370      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
371        are now exclusive)
372      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
373        required re-ordering the code a little:
374       + make DAIRN global variable (defined in SEAICE)
375       + move computation of the viscosities eta and zeta into a new separate
376         routine (because I need to recompute them in seaice_ocean_stress.F)
377    
378    checkpoint58b_post
379    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
380      update output.txt of exp. aim.5l_cs.thSI
381    o various mnc cleanups and improvements:
382      + shrink lookup tables by factor of ~4
383      + better error reporting when running out of lookup space
384      + able to handle longer path/file names (up to 500 chars)
385    o adjoint:
386      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
387      - TBD: "hidden" mom_vecinv recomp. in dynamics
388    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
389     (allow to differentiate between forcing components using new integer flags:
390      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
391     and add new flag to put Dissipation tendency out of Adams-Bashforth.
392    o ecco
393      - enable trend removal from SSH anomaly obs.
394    o adjoint
395      - a fix for PmEpR when #undef EXACT_CONSERV
396      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
397      - try to fix "hidden" recomp. in forward_step for NLFS
398        (NLFS seems broken sometimes after I checked it in)
399    o seaice:
400     - add c-grid version of the dynamic solver:
401       + three new routines that are the c-grid substitute lsr, dynsolver
402         and ostres
403       + put a few fields that were local to dynsolver into global common
404         blocks, so that I can move the computation of stresses etc into
405         seaice_lsr (saves coding but may break the adjoint).
406     - replace more hardwired parameters by runtime parameters
407     - add ice masks that mask the rhs of the implicit solvers where there
408       is no ice (commented out in seaice_dynsolver, because i am not sure
409       if this works properly), eventually this should replace the clipping
410       of ice velocities in seaice_dynsolver to +/-40cm/s.
411    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
412      include it only where its needed
413    o move balancing of fluxes before the call of external_forcing_surf
414    o seaice:
415      - correct units of turning angles (now they are really in degrees)
416      - move computation of GWATX/Y out of main routine into dynsolver
417      - initialize GWATX/Y in seaice_init
418    o Apply mask on Fresh-Water flux (needed for SSH forcing).
419      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
420    o seaice: add runtime flags for turning angles (default to zero)
421    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
422      and trend from exf forcing and ctrl control adjustments
423    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
424      (since checkpoint57x_post)
425    o change the default rotation period to 86164.s = the Earth rotation
426    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
427      and based on a reference stratification. Tested within hs94.cs-32x32x5.
428    o seaice advection: add code for choosing between the default (2nd order
429      central differences) and multiDim advection schemes provided by
430      pkg/generic_advdiff
431    o seaice:
432      - removed all references to SEAICE_GRID.h fields from
433        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
434        (cubed-sphere configuration will change a little)
435      - grid computations in seaice_init are obsolete now.
436      - cleaned up code a little so that is easier to read (hopefully).
437      - added new (better?) discretizations of default advection and diffusion
438        (turn on with SEAICEuseFluxForm)
439      - replace 1 in 3d global fields by kSurface in growth.F
440      
441    checkpoint58a_post
442    o seaice:
443      - bug fix in advect.F
444    o shelfice:
445      - separate shelfice load anomaly from pload (breaks with time
446        dependent forcing), => introduce constant field shelficeLoadAnomaly.
447        Its default is 0., but it may be computed more cleverly from (unknown)
448        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
449        done offline. A good approximation of the pressure load anomaly is
450        necessary to avoid large initial adjustment processes underneath
451        deep-reaching shelfice.
452      - small fix in ISOMIP shelfice_thermodynamics
453      - add more sophisticated thermodynamics of Hellmer (1989), this is
454        now the default
455      - give a few constants more intuitive names
456    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
457      if bulk formulae are used in long integration (especially EmPmR). Turn
458      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
459      if balancePrintMean, the imbalance that is substracted is printed to
460      STDOUT.
461    o fix bug (typo) in obcs_apply_eta.F
462    o add a new package shelfice which enables us to model the circulation
463      underneath shelf-ice with draughts of hundreds of meters.
464     - works
465     - to do: + include improved thermodynamics
466              + check whether kSurfC (from model/inc/SURFACE.h) can be used
467                instead of new field kTopC
468              + can we use topoFile, Ro_surf and existing code in ini_depth.F
469                instead of new field R_shelfIce and new code in ini_depth.F
470                and ini_mask_etc.F?
471              + adjust vertical mixing schemes?
472    o seaice pkg:
473     - add a cpp-flag to include a simple formula for a salinity dependent
474       freezing point of sea water at the surface
475     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
476       meridional stresses are now different (and hopefully correct)
477    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
478       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
479       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
480    o pkg/diagnostics: add options and parameters for regional-statistics
481       diagnostics ; define regions by reading a region-mask from a file
482       (might add other options later)
483    o pkg/bulk_force:
484     - add option and parameters to use AIM surface-flux formulae.
485     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
486       others forcing fields (defined in PARM05, parameter file "data") are loaded
487       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
488     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
489     - use the right EXCH call for uwind,vwind (to work on CS-grid).
490     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
491       and parameters (note: calcWindStress replaces .NOT.readwindstress).
492     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
493    
494    checkpoint58
495    o add "--embed-source" option to genmake2 which, when the supporting
496      tools can be compiled (as determined by genmake2) will turn on the
497      embed_files package which then embeds the entire MITgcm source code
498      (*.[fFhc] + Makefile) used for the build within the executable
499      - requested by CNH but off by default
500      - adds a paltry <9MB to the mitgcmuv executable in most cases
501      - only writes the output when useEMBEDSRC in eedata is true
502    o clean up 3-dim. relaxation codes:
503      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
504      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
505      * Thanks to Tom Haine for testing!
506    
507    checkpoint57z_post
508    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
509      affects output (@ truncation level) of exp. plume_on_slope ; updated.
510    o fix the pickup behavior for obcs in combination with ptracers
511    o fix a bug in ptracers_external_fields_load
512    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
513      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
514    o transfered surface NH pressure to eta field (if exactConserv).
515    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
516         and update lab_sea output.txt file.
517    o completing 3-dim. relaxation code: additional term
518         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
519      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
520      * At compile time, in "EXF_OPTIONS.h" set
521          #define  ALLOW_CLIMTEMP_RELAXATION
522          #define  ALLOW_CLIMSALT_RELAXATION
523      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
524          tauThetaClimRelax3Dim = 15552000.0,
525          tauSaltClimRelax3Dim  = 15552000.0,
526      * 3 cases:
527          1) Use a constant-in-time 3-dim. field
528          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
529          3) Real-time relax. to time-evolving prescribed field
530    o Adding Laplacian-type smoothness constraint on
531      initial and boundary (forcing) controls (ic, bc)
532      * enable at compile-time via
533        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
534      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
535      * Absolute scale somewhat unclear so far
536      * no area weighting was included since no other cost term does so far
537    
538    checkpoint57y_post
539    First step for a NLFS adjoint
540    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
541    o new init. routines for calc_r_star, calc_surf_dr
542    o still need to deal with ini_masks_etc
543    o testreport seemed happy
544    checkpoint57y_pre
545    
546    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
547    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
548    o add new offset feature to offline pkg (plus minor cleanup)
549    o cfc fixes for final year of integration
550    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
551      be in GCHEM_OPTIONS).
552    
553    checkpoint57x_post
554    o fix testreport Pb in multiple test experiment.
555    o cleanup our namelist syntax in verification:
556      - make it more F95 standards compliant (some work still needed)
557      - allows the vast majority of our tests to work with gfortran
558    o Non-Hydrostatic:
559     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
560     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
561    o Allow to apply AB on T,S rather than on AB(gT,gS):
562     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
563     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
564       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
565     - need a "clever" read_pickup to restart from the other AB formulation
566    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
567    o remove some unused variables (reduces number of compiler warnings)
568    o adjoint
569      * Disable useVariableViscosity for adjoint for time being
570        (there are a number of extensive recomputations)
571      * Initialize certain variables needed for adjoint
572    
573    checkpoint57w_post
574    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
575                 fix the singleCpuIO RS version of MDSWRITEFIELD
576       and add a WARNING if using globalFiles=T with multi-processors.
577    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
578      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
579    o tracer advection scheme:
580      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
581       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
582       was not very convenient).
583      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
584       (further tests needed for the implicit DST & Flux-Limiter schemes).
585    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
586      and sRef for convenience, handy, when you want to initialize
587      ptracers in a large domain with a constant non-zero value. Also,
588      untangle ptracers_init.F a little.
589    
590    checkpoint57v_post
591    o change dome exp. to use variable viscosity in side-drag terms.
592    o remove all the files from the cfc_offline test since they are now
593      incorporated into tutorial_cfc_offline which has been producing
594      identical results for a few days of testing
595    o add new parameter: sideDragFactor to enable half-slip-side BC
596      and change side-drag S/R to use viscosity from mom_calc_visc
597      (can switch back by setting sideDragFactor=0.); affects results at
598      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
599       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
600    o vorticity & strain are now computed without masking, to account for
601      no-slip-side BC in variable viscosity calculation ; mask is applied
602      anyway later on, before computing advection/coriolis terms.
603    o modify exp4 to test new obcs support for reading from external files
604      and for passive tracers
605    o fix behavior of ptracers_monitor when monitor output is written to a
606      netcdf-file; still not independent of monitor.F (writes in the same
607      file).
608    o change default value of tRef (put a uniform, meaningful value for ocean
609      & atmos) and initialize sRef (was missing, as Martin mentioned).
610    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
611      to be proportional to enstrophy dissipation length.  Thus,
612       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
613      This is now consistent with Smagorinsky and with the manual.
614    
615    checkpoint57u_post
616    o OBCS and PTRACERS: add open boundary support for passive tracers
617      - either use homogenous (pseudo) v.Neumann conditions or prescribe
618        OB-values from file; this is not different from the way theta and salinity
619        are treated
620      - however, Orlanski-radiation conditions are not supported, and the model
621        will stop if you use pTracers and Orlanski at the same time.
622      - beefed up the rountine obcs_external_fields_load: now only those open
623        boundary values are overwritten with values from files for which there
624        are really files, otherwise the OB-fields remain untouched. This makes
625        it possible to use different OBs at different ends of the domain (as
626        with EXF)
627    o reduce number of exch calls in shap_filt (s2).
628    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
629      truncation level) 4/5 MLAdjust test results (11&12 digits match).
630    
631    checkpoint57t_post
632    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
633    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
634      same truncation, independent of the face number: affects affects several
635      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
636    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
637      note that biharmonic viscosity + no-slip was not tested in any experiment.
638    o fix bug in non-linear free-surf side-drag ; generate new output for
639      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
640    o make mnc honor the writeBinaryPrec flag for most kinds of output
641    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
642    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
643      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
644    o add brackets in multi-terms sum to get same truncation, independent of
645      the face number (manage to get exactly same value of gU,gV at the cs-edge)
646      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
647    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
648      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
649      a maximum grid-scale Reynolds number.  Also, changes all length calculations
650      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
651      Suggested values of viscosity parameters found in mom_calc_visc.
652      Many new viscosity diagnostics available.
653    
654    checkpoint57s_post
655    o Add clearing-house for viscosity calculations, mom_calc_visc and
656      correct numerous bugs in LeithD and Smagorinsky discretizations.  
657      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
658      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
659      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
660      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
661      The Strain-Tension form is now called with useStrainTensonVisc=.true.
662      ViscAhStrain and viscAhTension are now retired.
663    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
664    o In response to JMC's bug report, genmake2 now ignores any soft-links
665      that it finds in the *current* directory when searching for files.
666      Soft-links found in any other source directories will still work as
667      they did before.
668    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
669      a C routine to unlimit the stack size
670    o mnc-ify pkg/aim snapshot vars
671    o mnc-ify pkg/land as requested by Daniel
672    o various changes to mnc including:
673      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
674      - output can now be grouped so that all files within a group
675          change the ITER portion of their names in lock-step together
676      - can now read ("global") PER-FACE (in addition to PER-TILE) files
677          and works with both EXCH1 and EXCH2 (but needs more testing)
678      - writing works for all verification test cases w/ g77 on Linux
679    
680    checkpoint57r_post
681    o make MNC variable initialization happen earlier
682    o add diagnostics for (almost) each term of the momentum Eq.
683    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
684    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
685    o remove MINIMAL_TAVE_OUTPUT option ;
686      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
687    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
688      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
689    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
690    o add time-dependent SST, SSS control
691    o cost terms in ecco/ modularized (new cost_generic.F)
692    o cost_averages routines are modularized (new cost_averagesgeneric.F)
693    o new infrastructure for seaice model vs. obs misfits in seaice/
694      * driver from the_main_loop.F is seaice_cost_driver.F
695      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
696      * gradient check in Exp. 6a of natl_box_adjoint/
697    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
698      (see README file)
699    
700    checkpoint57q_post
701    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
702    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
703      - bug was reported by Jean-Michel and Ian Fenty
704    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
705      update exp. cpl_aim+ocn output.
706    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
707      Needed for high-res. runs with large global files
708      to be able to limit tapelev size
709    o Changed some tests for adjoint:
710      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
711      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
712      * global_ocean.90x40x15/ back to default 3-level checkpointing
713    o Modifications to enable scripted COMMON to MODULE conversion
714      * verification/OpenAD/code/ has necessary scripts and description;
715      * converts, compiles and runs successfully;
716    
717    checkpoint57p_post
718    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
719    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
720      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
721    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
722    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
723      (was already the case for dissipation with mom_vecinv,
724       and also the case for grad.PhiHyd when staggered-timeStep)
725      This will allow to put dissipation out-off the AB time-stepping.
726     Unfortunately, affects truncation error. Update output of exp. that "fails"
727      (cg2d matching number) and leave the others for later: front_relax(10),
728      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
729      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
730    
731    checkpoint57o_post
732    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
733      (2) its ready to be documented during the 20050801 DocFest
734    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
735      for ideal_2D_oce and lab_sea on linux_ia32_g77
736    o set to #undef CTRL_SET_OLD_MAXCVARS_30
737      in global1x1_tot/code_seaice_adj to access indices 32, 33
738      (worth another tag)
739    
740    checkpoint57n_post
741    o adding precip control xx_precip 32
742    o adding swflux control xx_swflux 33
743    o Replacing 10 forcing penalty cost routines by 1 generic.
744    o Implementing partitioning in time-mean and variable adjustment
745      for atmos. state.
746    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
747    o in natl_box_adjoint:
748      * updated exp 1 to 10
749        (but does not have time-mean vs. variable split results yet)
750    o updated global1x1/*_seaice_adj/
751      to incorporate latest changes
752    o enable useSingleCpuIO for mdsio vector routines
753      (applies in particular to tapelev I/O)
754    o removed inefficient K-loop in all active_file*control*.F
755    
756    checkpoint57m_post
757    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
758      and advect_cs (use EXCH-2 and standard cs-32 grid files).
759    o pkg/exch2: filling of face-corner halo regions is optional
760      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
761    
762    checkpoint57l_post
763     tag before updating tutorials (pre-release-2)
764    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
765       for output and interpolation of input fields onto model grid)
766    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
767       Affects results of exp. rotating_tank ; update output.txt.
768    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
769          and taking the square quantity and/or using a fraction-weight field.
770    o fix aim_diagnostics_init.F mate numbers.
771    o add mnc output capability to diagnostics/diagstat and update
772      our cvsignore files for the ACSII output generated
773    
774    checkpoint57k_post
775    o lab_sea now uses diagnostics package and provides a suite of
776      new EXF diagnostics output.
777    
778    checkpoint57j_post
779    o exf
780      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
781        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
782        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
783      * extended diagnostics output
784        - now includes all EXF variables
785        - hs, hl moved to common block
786        - separate S/R for diagnostics, called after ctrl vector is added
787        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
788        - EXFqnet contains true Qnet (i.e. includes qsw)
789      * updated verif. lab_sea, global_with_exf
790      * Rearranging hflux (exf_mapfields -> exf_getforcing)
791        to ensure that diagnostics sees a true EXFqnet
792    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
793    o diagnostics pkg: change pointers so that 1 diagnostic can be used
794      several times with different frequencies.
795    o mnc-ify the thsice package as requested by Daniel Enderton
796      - the monitor--MNC output needs work
797      - many attributes need to be added (most are currently blank)
798    o mnc-ify theaim_v23 package as requested by Daniel Enderton
799      - many attributes need to be added (most are currently blank)
800    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
801    o add Sadourny like discretization to the 4th.O vorticity advection scheme
802    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
803      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
804         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
805    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
806     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
807    
808    checkpoint57i_post
809    o Diagnostics package was changed: diagnostic allocation is now deactivated
810      by setting an empty file name in the namelist (used to be by setting 0 frequency)
811    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
812      add 1rst Order upwind vertical Shear.
813    o add a quick fix for A/B checkpointing in OFFLINE mode
814    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
815      end-run around the C/Fortran linking horror in eesup/src/timers.F
816    o added pkg/runclock: allows user to terminate run based on wall clock
817    o added non-hydrostatic scaling parameter: nh_am2
818    o pkg/my82: futile attempt to make results compiler-independent by adding
819      some "_d 0", etc. no effect.
820    o for mnc output, fill the 'T' coordinate var with myTime and create a
821      separate 'iter' variable for iteration count
822    o pkg/diagnostics:
823      add new capability: output of Global/Regional & per-level statistics ;
824      tested against monitor output (including land & thSIce) on various exp.
825    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
826    
827    checkpoint57h_done
828      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
829      data.diagnostics, data.gchem, data.ptracers) is done.
830    
831    o pkg/diagnostics: prepare for Global/Regional statistics.
832      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
833    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
834      and rename it: DIFFERENT_MULTIPLE
835    
836    checkpoint57h_post
837    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
838    o pkg/diagnostics: change output frequency, now in seconds (instead
839      of Nb of iterations). This requires to change data.diagnostics.
840    checkpoint57h_pre
841    
842    o in mnc, let the user create the output dir if both mnc_outdir_date
843      and mnc_outdir_num are false
844    o add fflags() to pkg/diagnostics which allows one to specify, on a
845      per-file basis, the file precision [default behavior is unchanged]
846    o added diagnostics to pkg/kpp, including computation of mixed layer
847      depth based on a temperature/density criterion
848    o updated verification/natl_box to test the new pkg/kpp diagnostics
849    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
850    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
851    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
852      not mnc -- this mistake was found by JMC and is now corrected
853    
854    checkpoint57g_post
855    o add Adams-Bashforth 3rd Order time stepping:
856      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
857      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
858    checkpoint57g_pre
859    
860    o make lambda[Theta,Salt]ClimRelax spatially varying
861      (default remains spatially uniform constant based on tau)
862    o added new control variables
863      * init. uVel, vVel, etanN
864      * lambda[Theta,Salt]ClimRelax
865    o separate masks used for ctrl_pack/unpack 'from write_grid' output
866      (suggested by G. Forget)
867    
868    checkpoint57f_post
869    o add parameter "baseTime" = model base time = time at iteration zero
870      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
871      account for baseTime shift
872    o move Coriolis arrays from PARAMS.h to GRID.h
873    checkpoint57f_pre
874    
875    o mnc-ifying the seaice package
876    o introduced an alternative length scale calculation for use in the limiting
877      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
878    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
879    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
880      as well as grad(vort3).  Made it compatible with both approximate form
881      for the cubed sphere and full form of these gradients.  Added flag
882      useFullLeith to select between approximate and full form.  
883    o add "d0" in getcon.F to reduce differences between compilers/platforms
884      update output.txt of exp. fizhi-gridalt-hs
885    o change port_rand funtion to allow to set the seed.
886    o fix obscure MNC bug involving conversion between reals and integers
887      - it caused no problems with certain (eg. gcc, ifc) compilers but the
888        new version is now more standards-compliant
889    o adjoint-related modifications
890      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
891      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
892      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
893    
894    checkpoint57e_post
895    o Adding eddy stress controls a la Ferreira et al.
896    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
897    
898    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
899      update output.txt of exp. fizhi-gridalt-hs
900    o add more "Z" dimensions and associated coordinate vars to MNC
901    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
902    o parameter calendarDumps: when set, approximate months (30-31 days) and years
903      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
904      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
905      months and years.  Requires pkg/cal.
906    o diagnostics: add pickup functionality
907      - off by default for backwards compatibility
908      - current version only uses MDSIO -- MNC will be added
909    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
910    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
911    
912    checkpoint57d_post
913    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
914    o modify verification/ideal_2D_oce so that it tests the creation of mnc
915      output from the diagnostics package
916    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
917    o make genmake2 more portable by using ".$FS" instead of ".f" for more
918      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
919    o add coordinate variables to the MNC output from the diagnostics package
920    o change MNC-flags default value: true when useMNC=TRUE
921    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
922      the ability (off by default) to read the grid information using MNC
923    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
924    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
925    o do snap-shot diagnostics at the middle of the time-interval (instead of
926      at the end).
927    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
928      new test for AIM with thSIce + slab-ocean
929    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
930    o move state variable diagnostics to the beginning of the time step ;
931      (note: still needs some work specially for snap-shot diagnostics)
932      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
933    
934    checkpoint57c_post
935    o Change testing option (-ieee) to get closer agreement between g77 & ifort
936    o generate new output.txt files on faulks with g77 & the new -ieee option
937    checkpoint57c_pre
938    
939    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
940      update output.txt of exp. global_ocean.90x40x15
941    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
942      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
943    o add saltFlux(+File) forcing capability with periodicExternalForcing
944    o allow to use pkg diagnostics for GM-Redi & ThSIce output
945    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
946    o improvements for the MNC output from DIAGNOSTICS:
947      - correct handling of the unlimitied dimension
948      - all dims now have associated coordinate variables
949      - variables located at U, V, and Corner ("Z") points are now written
950        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
951        *all* data points are output
952    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
953    o added pkg/seaice/seaice_monitor.F
954    o mdsio_readfield.F can now read files visible only to master MPI process.
955    o pkg/seaice: some test code for ice-modified ocean stress
956    o exf_getffields interpolation defaults to bilinear for all scalar forcing
957      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
958      spurious negative numbers for precipitation and humidity.  Will cause
959      some small numerical differences for integrations using pkg/exf/exf_interp.F.
960    o pkg/ctrl/
961      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
962        May be enabled via doPackDiag
963      *  introduce z-scaling of
964         + gradient (doZscalePack) and
965         + control (doZscaleUnpack)
966    o pkg/mdsio/
967      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
968      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
969    
970    checkpoint57b_post
971    o simplify options in diagnostics_fill arguments (remove weird combinations)
972    o fix MNC coordinate variables so that they now contain per-face index
973      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
974      general, EXCH2 grids are only aligned to a "local" coordinate system
975    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
976    o Implement instantaneous output within pkg diagnostics:
977      setting a negative frequency in data.diagnostics produces
978     "snap-shot" output (as opposed to time-average if freq > 0)
979    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
980      NOTE: change ptracer diagnostics name: use 2 characters to work with
981            more than 9 tracers. Add also diagnostics of advect & diffus flux.
982    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
983      becomes the coordinate variable for the 'T' dimension
984    o add CF-style coordinate variables to MNC
985      - just a first cut:  numbers are meaningless on the cubesphere and
986        missing along the T axis but otherwise it works!
987    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
988    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
989    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
990      this is based directly on what the model compute, so that the content of
991      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
992    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
993    o clean up build options files for SunOS, in particular
994      - remove -traditional from xmakedepend
995      - change -xarch=v9 to -xarch=native for f77
996      - restore use of make (not gmake)
997      - add CC=gcc if using g77
998    o changes per discussion of AM, JMC, & EH3 today:
999      - move redundant "grid" variables out of "state" -- in preparation of
1000        creating proper CF-style coordinate variables and in recognition
1001        that any/all grid variables can be easily copied (eg. w/NCO) from
1002        the grid files into any of the other NetCDF files
1003      - *always* output grid variables with MDSIO (this will eventually be
1004        changed)
1005      - output MNC grid file if useMNC is true
1006    o every instance of _END_MASTER() has been found and replaced with
1007      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1008      preprocessors
1009    o re-arrange diagnostics pkg initialisation:
1010     - allow each package to extend the available diagnostics list
1011     - add some checking and fix small problems (multi-threaded, ...)
1012     - new S/R diagnostics_fill (replace fill_diagnostics):
1013       look through the short list of active diag. (instead of the long list)
1014       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1015    
1016    checkpoint57a_post
1017    o this set of changes restores TAMC compatibility
1018      tested for global_ocean.90x40x15 adjoint on trough
1019      (what a pain)
1020    
1021    checkpoint57a_pre
1022    o some modifs in tools/build_options for sunos
1023    o call ctrl_pack for ctrl at end for optimcycle=0
1024    
1025    checkpoint57
1026    o add horizontal bi-harmonic viscosity for vertical velocity
1027      - new parameter viscA4W (defaults to viscA4)
1028      - affects only non-hydrostatic code
1029      - to be done: no-slip lateral boundary conditions
1030    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1031    o implement Implicit Vertical advection for pTracers
1032    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1033      (implemented also for implicit vertical diffusion & advection)
1034    o OBCS: extend application of tracer open boundary conditions
1035      to a strip beyond the boundary of width Olx/Oly
1036    o add call monitor to TAF set of required calls (flow directives)
1037      and include in natl_box_adjoint
1038    o untangle a few ifdefs related to cost, ctrl, autodiff
1039      untangel a few ALLOW_ECCO_OPTIMIZATION
1040    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1041      (theta2, salt2 in ecco_cost_weights)
1042    
1043    checkpoint56c_post
1044    o OBCS as control variables
1045      - update ctrl_ad_diff.list, obcs_ad_diff.list
1046      - remove balance of obcs controls from default
1047      - fix index bug nobcs in ctrl_init
1048      - fix dummy fields filen in ctrl_pack
1049      - add dummy weights for obcs
1050    o lsopt: comment out fort.94 output
1051    o optim:
1052      - remove unnecessary header files
1053      - adjusted namelists
1054      - add xerbla.F to Makefile
1055    o exf:
1056      - multiple modifications of exf_check_range
1057      - unit change in exf_init_runoff from [m/year] to [m/s]
1058    o mdsio:
1059      - i/o-vector change debugLevel from debLevA to debLevB
1060    
1061    checkpoint56b_post
1062    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1063      is called from DO_THE_MODEL_IO
1064      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1065      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1066      - clean up PTRACERS_WRITE_TIMEAVE a little
1067    o add another verification experiment that tests both the cfc-pkg and
1068      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1069      reactive tendencies treated inline with regular timestepping
1070    o testreport previously did a lousy job of comparing small numbers, so
1071      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1072      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1073      testreport.
1074    o ptracers_monitor: bug fix for MPI
1075    
1076    checkpoint56a_post
1077    o GCHEM: finish reorganizating the package
1078      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1079        (introduces another 3D-array for each passive tracer, but only if
1080        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1081        gchemTendency is not needed because the timestep is done separately)
1082      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1083      - GCHEM is now---more or less cleanly---separate from PTRACERS
1084      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1085        so clear to me how that should be done in a general way.
1086    o CFC: improve formatting of output in CFC_ATMOS
1087    o PTRACERS:
1088      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1089        that ALL experiments with ptracers enable can be checked. This makes
1090        GCHEM_MONITOR obsolete.
1091      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1092        monitorFreq
1093      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1094    o add PTRACERS (PTR0[1-5]) to testreport output
1095    o exf_check_range:
1096      * default changed to .TRUE.
1097      * will check values for niter0 if debLevA, every timestep if debLevB
1098      * STOP in exf_check_range if 'out of range'
1099      * range chosen generous to allow for potential extema
1100      TBD: a version with stricter range
1101           permitted range would be runtime parameters

1109    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1110      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1111        this flag is now only visible within GCHEM-pkg routines.
1112      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1113        be replaced by a 3D array that is computed before thermodynamics; for
1114        this, the tracer ID iTracer had to be included into the parameter list
1115        of ptracers_forcing
1116      - set up forward_step to call gchem_forcing, that will replace
1117        gchem_forcing_int in ptracers_forcing
1118      - cleaning up
1119  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
