5      ==============================      ==============================
6    
7    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
8      directly to drive seaice model (C-grid only)
9    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
10     - reintroduce computation of wind from stress,
11     - compute tau (in exf_bulkformulae.F) from windstress averaged to
12       mass points to avoid tau = 0
13    o rdmnc.m: make it work with "global" files created with gluemnc
14    o rdmnc.m : some improvements in dealing with singleton dimension
15      (tested on all testreport mnc output files).
16    o genmake2: disable pkg/profiles if netcdf test fails.
17    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
18    o move call to cal_readparms up to make calendar parameters/variable available
19      to all packages
20    
21    checkpoint58v_post
22    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
23      useDynP_inEos_Zc tested.
24    o pkg/exf: changes to properly interpolate/mask/scale initial fields
25    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
26      and portions thereof.  See read_cs.txt for description and examples.
27    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
28      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
29      following the great-circle arc between those 2 points.
30    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
31      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
32    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
33     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
34     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
35     - still needs work (not working with some options ; efficiency to improve)
36       and serious testing.
37     - use this scheme for temperature & salinity in 2 advection test exp.:
38       advect_xy & advect_xz, respectively.
39    
40    checkpoint58u_post
41    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
42    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
43    o testreport: add option "-skipdir" to skip some test.
44    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
45      momentum calculation.
46    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
47    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
48      remove checkpoint.F and the_correction_step.F (no longer used);
49      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
50    o add option (linFSConserveTr) to correct for tracer source/sink due to
51      Linear Free surface
52    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
53    o pkg/thsice: fix reading mnc-pickups
54    
55    checkpoint58t_post
56    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
57    o pkg/mdsio:
58     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
59       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
60       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
61     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
62     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
63       either MDS_READ_FIELD or MDS_WRITE_FIELD )
64     - new S/R (to replace MDSWRITEMETA), which allows to write more
65       informations (variable names, time ...) to meta files.
66     - modify rdmds.m to give back the meta file content.
67    o pkg/diagnostics: change vertical interpolation to be safer, and more
68       flexible (define p-levels to interpolate to in data.diagnostics);
69      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
70       diagnostic pointer.
71    o pkg/seaice: more cleaning up of seaice_growth, added many comments
72    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
73    o fix multi-category seaice:
74     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
75       SEAICE_MULTICATEGORY
76     - fix short wave heat flux
77    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
78       and allow to use EVP solver. Change forward lab_sea: test both EVP
79       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
80    o Initial check-in of lab_sea adjoint
81      (very similar to natl_box_adjoint/code_seaice)
82      * used C-grid and EVP solver
83      * used KPP, GM/Redi
84      * uses inAdExact=.TRUE.
85      * gradient checks fail for both ADM and TLM
86        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
87        f.d. gradients actually seem more problematic than ADM, TLM gradients;
88        issue is related to forward mismatch between g77 an ifort
89    o pkg/seaice: overhaul of thermodynamics
90     - growth.F and groatb.F are replaced by new routine seaice_growth.F
91     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
92     - move a few global fields out of SEAICE.h into seaice_growth.F and
93       make them 2D (FICE/QNETO/ ...)
94     - remove FO (it is the same as QNETO)
95     - introduce a few local fields to avoid modifying external fields such
96       as atemp, etc.
97    
98    checkpoint58s_post
99    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
100      changed exf_set_gen.F so that
101        genperiod=0 means input file is one time-constant field and
102        genperiod=-12 means input file contains 12 monthly means
103    o CG2D: use pre-computed solver main-diagonal (stored in common block);
104      this affects truncation error ; generate new output file for exp. which
105      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
106        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
107        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
108        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
109        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
110        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
111    o start implementation of deep-atmosphere and anelastic formulation
112    o verification: remove 2nd copy of input files and use script "prepare_run"
113      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
114    o mom_common/vecinv/fluxform: fix a few initialisation isssues
115    o profiles: fix for multithreaded case
116    
117    o diagnostics: rename few diags:
118      s/'PRESSURE'/'RCENTER '/g
119      s/'TICE    '/'oceFreez'/g
120      s/'TAUX    '/'oceTAUX '/g
121      s/'TAUY    '/'oceTAUY '/g
122      s/'SWFLUX  '/'oceQsw  '/g
123      s/DIFx/DFxE/g
124      s/DIFy/DFyE/g
125      and add few ocean-forcing diagnostics:
126      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
127    o modifications to pkg/seaice/growth.F and budget.F, which change results of
128      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
129      as actual snow thickness.  It now refers everywhere to effective snow
130      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
131    
132    checkpoint58r_post
133    o modifications to pkg/seaice/growth.F, which change results of
134      lab_sea experiment: fixes pertain to melting snow over open water, to
135      masking EVAP under sea ice, and to using the correct AREA variable for
136      computations of EVAP, PRECIP, HSNOW, and GHEFF
137    o add ability to read bathy, salt, and theta using MNC (off by def)
138    o add flooding algorithm and advection of HSNOW for pkg/seaice;
139      both are turned off by default and do no change any results
140    o seaice advection with pkg/thsice: a step toward the use of non-linear
141      advection scheme, but #ifdef or commented out for now (requires more EXCH).
142    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
143      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
144      in natl_box (affects results @ truncation level: update output.txt)
145    o multi-threading and IO:
146      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
147      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
148        (needed to work with SingleCpuIO): tested in all verif. exp.
149    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
150      affects the results (but none of the verification test uses this scheme).
151    o Adding some pkg/diagnostics capability to pkg/seaice
152      (will certainly be subject to changes)
153    o ctrl: adding new control variables:
154      lwflux, lwdown, evap, snowprecip, apressure, runoff
155    
156    checkpoint58q_post
157    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
158      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
159      high_res_cube configuration by 4% on Columbia.
160    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
161      add (in global_with_exf/code) a version of EXF_INTERP_READ without
162      dynamical allocation (seems to work in multi-threaded).
163    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
164      single CPU io) so that TAF does not have to see EESUPPORT.h
165    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
166    
167    checkpoint58p_post
168    o obcs: stop if obcs is used with useCDscheme = .true.
169    o shelfice:
170     - fix a sign error so that no slip at shelfice interface works
171     - remove stop for combination non-hydrostatic code and shelfice. That does
172       not mean, that the results are correct, but at least they are numerically
173       stable
174    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
175    o added adjoint exch routined for all exch*3d* routines
176      and updated flow directives
177    
178    checkpoint58o_post
179    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
180      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
181    o change controling S/R for writing pickup file (new S/R do_write_pickup)
182      and clean-up reading/writing of pickup files.
183    o fix local version of read/write pickup (NH part) in rotating_tank/code
184    o simplify EXCH interface:
185     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
186     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
187    o added the regrid package
188    o shelfice:
189     - add a simple boundary layer scheme to reduce noise
190     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
191    
192    checkpoint58n_post
193    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
194       local variable (not in common block).
195    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
196      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
197      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
198        to work with SingleCpuIO.
199    o add "_d 0" to real constant of pkg/cfc subroutines ;
200       update exp. cfc_exemple & tutorial_cfc_offline output files.
201    o multi-threading and IO:
202      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
203        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
204      - barrier before and after reading.
205      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
206      - avoid using MDS_WRITELOCAL for LAND pkg output.
207      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
208        common-block variables ; Allows multi-threading with master-thread IO.
209    o change default MAX_NO_THREADS from 32 to 4 ;
210      and stop cleanly when MAX_NO_THREADS is too small.
211    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
212    
213    checkpoint58m_post
214    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
215       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
216    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
217       keep global_ocean.90x40x15 (for AD testing) with former secondary test
218       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
219    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
220        add MITgcm_tutorials (= code + all the tutorials)
221    o ecco, option to compute cost for total ssh (mean+anom)
222    o consistent with addition of ptracer and ssh in pkg/profiles
223    o profiles: adding ptracer and ssh
224    o testreport: change multi-test output-file name
225      (from output.txt.{name} to output.{name}.txt)
226    o profiles: now ok for mutli-tiles case
227    o seaice: add 4 parameters for different advection schemes for area,
228      (effective) seaice thickness, enthalphy, and snow height. Their default
229      is the standard parameter SEAICEadvScheme
230    o calc_gw:
231     - add cosFacU in zonal viscous flux (harmonic.visc.).
232     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
233       of tutorial_plume_on_slope.
234    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
235    o calc_gw: true flux-form, account for horizontal grid spacing.
236      update rotating_tank results, but not plume_on_slope (affected at
237      truncation level, 11 digits).
238    
239    checkpoint58l_post
240    o calc_gw:
241     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
242     - remove side-drag for now (need to fix it); update plume_on_slope results.
243     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
244    o commit code to make SST/SSS weights spatially variable
245      (based on either variable in-situ or variable initial T/S weights)
246    o pkg/ecco:
247      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
248        now based on horizontally varying weights wthetaLev, wsaltLev
249      * cost_averagesflags now returns year indices in addition to day, month
250      * sflux balance is performed on annual basis
251        (sflxumm, sfluxmm2, bal_sfluxmm)
252      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
253        including separate counting and multipliers
254    o pkg/rbcs
255      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
256    
257    checkpoint58k_post
258    o testreport:
259     - always build in dir. "build" (if not there, mkdir build instead of building
260       & running in input)
261     - run in dir run (if it exists), in build otherwise.
262     - call prepare_run (if input/prepare_run exists)
263     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
264    o pkg/exf modifications to interpolation and rotation routines for more
265       reasonable treatment of North Pole singularity: for tracers North Pole
266       value is set to northernmost zonal-mean value, for zonal velocity it is
267       set to zero, and for meridional velocity it is set to northernmost value.
268    o pkg/exf/exf_check_range.F
269     - add tile index to diagnostics and move stop statement to the very
270       end of the routine.
271    o pkg/diagnostics: (diagnostics_main_init.F)
272      define title of isomorphic variables according to the current config.
273    o pkg/thsice with pkg/seaice dynamics:
274    - fix domain of computation (interior only, required for exf) and do exchanges
275    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
276    o towards a standard way of dealing with multi-threading in MONITOR
277      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
278    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
279       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
280    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
281    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
282    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
283       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
284    o tracer advection:
285     - clean-up and simplify calc_common_factors.F
286     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
287       advection subroutine (but still not used within DST advection S/R)
288    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
289    
290    checkpoint58j_post
291    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
292      from file (collects calls previously in FORWARD_STEP)
293    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
294    o adjoint store dir. adjusted accordingly
295    o genmake2
296      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
297    
298    checkpoint58i_post
299    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
300      on wind stress (SEAICEstressFactor defaults to 1.)
301    o Total number of Timers is finite (<=40): comment out 2 non-essential one
302      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
303    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
304      on CS-grid: no longer loosing mass.
305    o exf & curvilinear-grid: no longer modify longitude xC & xG.
306    o pkg/ggl90: fix sloppy output and fix a bug
307    o pkg/seaice: added SEAICEuseEVPpickup parameter
308      - Set to false in order to start EVP solver with
309        non-EVP pickup files when using SEAICEuseEVP
310      - fix sign error in diffusion in seaice_calc_rhs
311    
312    checkpoint58h_post
313    * Modifications for bottom topography control
314      o replace hFacC by _hFacC at various places
315      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
316      o add non-self-adjoint cg2d_nsa
317      o update autodiff support routines
318      o re-initialise hfac after ctrl_depth_ini
319      o works for 5x5 box, doesnt work for global_ocean.90x40x15
320    * Adding verification for 5x5 box (4-layer) bottom topography control
321    
322    checkpoint58g_post
323    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
324       used for mean seasonal cycle, mean diurnal cycle); add an example
325       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
326    o pkg/ggl90:
327      - add parameter (minimum surface kinetic energy)
328      - fix bug (avoiding division by zero)
329    o couple pkg/thsice to pkg/seaice:
330      - modify advection in seaice to accomodate new scalar fields to be advected
331      - only muliDimAdection scheme work with seaice/thsice
332      - mapping of thsice-variables to seaice-variables, back and forth
333      - does not break the verification experiments, but does not give the
334        desired results either
335    o pkg/seaice
336      - make (default) second order advection a bit less confusing?
337    
338    checkpoint58f_post
339    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
340      to pkg/seaice):
341      - new routines thsice_map_exf and thsice_get_exf provide the interface
342      - add an additional formal parameter to thsice_solve4temp
343    o pkg/exf:
344      - add new fields wspeed, snowprecip (to be able to couple to thsice)
345      - correct Stefan-Boltzmann constant
346      - new parameter for longwave surface emittance
347      - separate some stuff from exf_bulkformulae into new routines  
348        exf_radiation, exf_wind
349      - add new parameters and constants: longwave emissivity for ocean, ice
350        and snow, evaporation parameters over ice
351      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
352        either wind from stress or stress from wind
353    o pkg/thSIce:
354    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
355    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
356       and THSICE_CALC_THICKN
357    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
358    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
359      to make debugging easier.
360    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
361    o pkg/bulk_force:
362      - clean-up comments and parameters ;
363      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
364    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
365      generate new output for test-experiment: aim.5l_cs.thSI
366    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
367      testreport accordingly
368    
369    checkpoint58e_post
370    o SEAICE_CGRID adjoint done
371    o R_STAR adjoint implemented.
372      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
373      * need to sort out init. of h0facc, etc.
374    o Make pkg/profile fully independent of ecco,cost, etc. stuff
375      to be able to use it in pure forward.
376    
377    checkpoint58d_post
378    o upgrade simple test-experiment to tutorial example:
379     step.1: duplicate the experiment and (step.2) will remove the old copy.
380      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
381      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
382      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
383      tutorial_global_oce_biogeo    <- copy of dic_example
384      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
385      tutorial_plume_on_slope       <- copy of plume_on_slope
386      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
387      tutorial_global_oce_optim     <- empty for now (David ?)
388      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
389     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
390    o correct a sign problem in cost_scat.F
391    o obcs and ptracers: fix boundary conditions for advections schemes
392      with larger stencil
393    o thsice adjoint: start
394    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
395      completeness
396    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
397      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
398    o ptracers adjoint:
399      * avoid extensive recomputatations
400      * fix missing re-init. of gptr (missed by TAF)
401    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
402      me to turn off the excessive output to STDOUT that this package produces
403    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
404      and add those terms in Vector-Invariant formulation.
405    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
406      if the control period (xx_hfluxperiod etc) is 0
407    o in profiles pkg, clean routines and fix details
408    o in ecco pkg, reading ssh data:
409      fix problem in case the model does not start at iter0=0
410    o fix mnc-pickup/restart for ptracers
411    o new package prifiles:
412      code to compute profile-based cost by Gael Forget
413      (modifs in ecco, ctrl, autodiff)
414    o Benign bug fix in initialization (spotted by M. Mazloff) of
415      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
416    
417    checkpoint58c_post
418    o adjoint: finish NLFS adjoint and provide reference output in
419      verification/global_ocean.90x40x15/results_ad_nlfs
420    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
421      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
422      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
423      with SEAICE_CGRID defined.
424    o move calendarDumps from "data" to "data.cal" and clean-up the code
425      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
426    o add useEXF & useCAL flags (for now, set in hard-coded way)
427    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
428      (were missing in NH mode, and wrong in quasihydrostatic mode).
429      waiting for Chris updated version of calc_gw to add those CALLs.
430    o fix bug in quasihydrostatic S/R ;
431      add a test for this option: global_ocean.90x40x15.qshyd
432    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
433      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
434    o add on/off flag useOffLine for package OFFLINE
435    o seaice:
436      - modify advection so that it works also on the C-grid
437      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
438        problem in multi-tile runs with C-grid
439      - add flags for clipping ice velocities and/or masking solver forcing
440      - fix drag (ocean on ice) formulation and a bug that caused noise in the
441        C-grid solver
442      - added a few comments to seaice_diffusion.F
443      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
444        are now exclusive)
445      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
446        required re-ordering the code a little:
447       + make DAIRN global variable (defined in SEAICE)
448       + move computation of the viscosities eta and zeta into a new separate
449         routine (because I need to recompute them in seaice_ocean_stress.F)
450    
451    checkpoint58b_post
452    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
453      update output.txt of exp. aim.5l_cs.thSI
454    o various mnc cleanups and improvements:
455      + shrink lookup tables by factor of ~4
456      + better error reporting when running out of lookup space
457      + able to handle longer path/file names (up to 500 chars)
458    o adjoint:
459      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
460      - TBD: "hidden" mom_vecinv recomp. in dynamics
461    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
462     (allow to differentiate between forcing components using new integer flags:
463      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
464     and add new flag to put Dissipation tendency out of Adams-Bashforth.
465    o ecco
466      - enable trend removal from SSH anomaly obs.
467    o adjoint
468      - a fix for PmEpR when #undef EXACT_CONSERV
469      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
470      - try to fix "hidden" recomp. in forward_step for NLFS
471        (NLFS seems broken sometimes after I checked it in)
472    o seaice:
473     - add c-grid version of the dynamic solver:
474       + three new routines that are the c-grid substitute lsr, dynsolver
475         and ostres
476       + put a few fields that were local to dynsolver into global common
477         blocks, so that I can move the computation of stresses etc into
478         seaice_lsr (saves coding but may break the adjoint).
479     - replace more hardwired parameters by runtime parameters
480     - add ice masks that mask the rhs of the implicit solvers where there
481       is no ice (commented out in seaice_dynsolver, because i am not sure
482       if this works properly), eventually this should replace the clipping
483       of ice velocities in seaice_dynsolver to +/-40cm/s.
484    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
485      include it only where its needed
486    o move balancing of fluxes before the call of external_forcing_surf
487    o seaice:
488      - correct units of turning angles (now they are really in degrees)
489      - move computation of GWATX/Y out of main routine into dynsolver
490      - initialize GWATX/Y in seaice_init
491    o Apply mask on Fresh-Water flux (needed for SSH forcing).
492      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
493    o seaice: add runtime flags for turning angles (default to zero)
494    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
495      and trend from exf forcing and ctrl control adjustments
496    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
497      (since checkpoint57x_post)
498    o change the default rotation period to 86164.s = the Earth rotation
499    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
500      and based on a reference stratification. Tested within hs94.cs-32x32x5.
501    o seaice advection: add code for choosing between the default (2nd order
502      central differences) and multiDim advection schemes provided by
503      pkg/generic_advdiff
504    o seaice:
505      - removed all references to SEAICE_GRID.h fields from
506        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
507        (cubed-sphere configuration will change a little)
508      - grid computations in seaice_init are obsolete now.
509      - cleaned up code a little so that is easier to read (hopefully).
510      - added new (better?) discretizations of default advection and diffusion
511        (turn on with SEAICEuseFluxForm)
512      - replace 1 in 3d global fields by kSurface in growth.F
513      
514    checkpoint58a_post
515    o seaice:
516      - bug fix in advect.F
517    o shelfice:
518      - separate shelfice load anomaly from pload (breaks with time
519        dependent forcing), => introduce constant field shelficeLoadAnomaly.
520        Its default is 0., but it may be computed more cleverly from (unknown)
521        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
522        done offline. A good approximation of the pressure load anomaly is
523        necessary to avoid large initial adjustment processes underneath
524        deep-reaching shelfice.
525      - small fix in ISOMIP shelfice_thermodynamics
526      - add more sophisticated thermodynamics of Hellmer (1989), this is
527        now the default
528      - give a few constants more intuitive names
529    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
530      if bulk formulae are used in long integration (especially EmPmR). Turn
531      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
532      if balancePrintMean, the imbalance that is substracted is printed to
533      STDOUT.
534    o fix bug (typo) in obcs_apply_eta.F
535    o add a new package shelfice which enables us to model the circulation
536      underneath shelf-ice with draughts of hundreds of meters.
537     - works
538     - to do: + include improved thermodynamics
539              + check whether kSurfC (from model/inc/SURFACE.h) can be used
540                instead of new field kTopC
541              + can we use topoFile, Ro_surf and existing code in ini_depth.F
542                instead of new field R_shelfIce and new code in ini_depth.F
543                and ini_mask_etc.F?
544              + adjust vertical mixing schemes?
545    o seaice pkg:
546     - add a cpp-flag to include a simple formula for a salinity dependent
547       freezing point of sea water at the surface
548     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
549       meridional stresses are now different (and hopefully correct)
550    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
551       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
552       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
553    o pkg/diagnostics: add options and parameters for regional-statistics
554       diagnostics ; define regions by reading a region-mask from a file
555       (might add other options later)
556    o pkg/bulk_force:
557     - add option and parameters to use AIM surface-flux formulae.
558     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
559       others forcing fields (defined in PARM05, parameter file "data") are loaded
560       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
561     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
562     - use the right EXCH call for uwind,vwind (to work on CS-grid).
563     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
564       and parameters (note: calcWindStress replaces .NOT.readwindstress).
565     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
566    
567    checkpoint58
568    o add "--embed-source" option to genmake2 which, when the supporting
569      tools can be compiled (as determined by genmake2) will turn on the
570      embed_files package which then embeds the entire MITgcm source code
571      (*.[fFhc] + Makefile) used for the build within the executable
572      - requested by CNH but off by default
573      - adds a paltry <9MB to the mitgcmuv executable in most cases
574      - only writes the output when useEMBEDSRC in eedata is true
575    o clean up 3-dim. relaxation codes:
576      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
577      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
578      * Thanks to Tom Haine for testing!
579    
580    checkpoint57z_post
581    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
582      affects output (@ truncation level) of exp. plume_on_slope ; updated.
583    o fix the pickup behavior for obcs in combination with ptracers
584    o fix a bug in ptracers_external_fields_load
585    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
586      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
587    o transfered surface NH pressure to eta field (if exactConserv).
588    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
589         and update lab_sea output.txt file.
590    o completing 3-dim. relaxation code: additional term
591         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
592      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
593      * At compile time, in "EXF_OPTIONS.h" set
594          #define  ALLOW_CLIMTEMP_RELAXATION
595          #define  ALLOW_CLIMSALT_RELAXATION
596      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
597          tauThetaClimRelax3Dim = 15552000.0,
598          tauSaltClimRelax3Dim  = 15552000.0,
599      * 3 cases:
600          1) Use a constant-in-time 3-dim. field
601          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
602          3) Real-time relax. to time-evolving prescribed field
603    o Adding Laplacian-type smoothness constraint on
604      initial and boundary (forcing) controls (ic, bc)
605      * enable at compile-time via
606        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
607      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
608      * Absolute scale somewhat unclear so far
609      * no area weighting was included since no other cost term does so far
610    
611    checkpoint57y_post
612    First step for a NLFS adjoint
613    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
614    o new init. routines for calc_r_star, calc_surf_dr
615    o still need to deal with ini_masks_etc
616    o testreport seemed happy
617    checkpoint57y_pre
618    
619    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
620    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
621    o add new offset feature to offline pkg (plus minor cleanup)
622    o cfc fixes for final year of integration
623    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
624      be in GCHEM_OPTIONS).
625    
626    checkpoint57x_post
627    o fix testreport Pb in multiple test experiment.
628    o cleanup our namelist syntax in verification:
629      - make it more F95 standards compliant (some work still needed)
630      - allows the vast majority of our tests to work with gfortran
631    o Non-Hydrostatic:
632     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
633     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
634    o Allow to apply AB on T,S rather than on AB(gT,gS):
635     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
636     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
637       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
638     - need a "clever" read_pickup to restart from the other AB formulation
639    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
640    o remove some unused variables (reduces number of compiler warnings)
641    o adjoint
642      * Disable useVariableViscosity for adjoint for time being
643        (there are a number of extensive recomputations)
644      * Initialize certain variables needed for adjoint
645    
646    checkpoint57w_post
647    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
648                 fix the singleCpuIO RS version of MDSWRITEFIELD
649       and add a WARNING if using globalFiles=T with multi-processors.
650    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
651      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
652    o tracer advection scheme:
653      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
654       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
655       was not very convenient).
656      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
657       (further tests needed for the implicit DST & Flux-Limiter schemes).
658    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
659      and sRef for convenience, handy, when you want to initialize
660      ptracers in a large domain with a constant non-zero value. Also,
661      untangle ptracers_init.F a little.
662    
663    checkpoint57v_post
664    o change dome exp. to use variable viscosity in side-drag terms.
665    o remove all the files from the cfc_offline test since they are now
666      incorporated into tutorial_cfc_offline which has been producing
667      identical results for a few days of testing
668    o add new parameter: sideDragFactor to enable half-slip-side BC
669      and change side-drag S/R to use viscosity from mom_calc_visc
670      (can switch back by setting sideDragFactor=0.); affects results at
671      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
672       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
673    o vorticity & strain are now computed without masking, to account for
674      no-slip-side BC in variable viscosity calculation ; mask is applied
675      anyway later on, before computing advection/coriolis terms.
676    o modify exp4 to test new obcs support for reading from external files
677      and for passive tracers
678    o fix behavior of ptracers_monitor when monitor output is written to a
679      netcdf-file; still not independent of monitor.F (writes in the same
680      file).
681    o change default value of tRef (put a uniform, meaningful value for ocean
682      & atmos) and initialize sRef (was missing, as Martin mentioned).
683    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
684      to be proportional to enstrophy dissipation length.  Thus,
685       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
686      This is now consistent with Smagorinsky and with the manual.
687    
688    checkpoint57u_post
689    o OBCS and PTRACERS: add open boundary support for passive tracers
690      - either use homogenous (pseudo) v.Neumann conditions or prescribe
691        OB-values from file; this is not different from the way theta and salinity
692        are treated
693      - however, Orlanski-radiation conditions are not supported, and the model
694        will stop if you use pTracers and Orlanski at the same time.
695      - beefed up the rountine obcs_external_fields_load: now only those open
696        boundary values are overwritten with values from files for which there
697        are really files, otherwise the OB-fields remain untouched. This makes
698        it possible to use different OBs at different ends of the domain (as
699        with EXF)
700    o reduce number of exch calls in shap_filt (s2).
701    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
702      truncation level) 4/5 MLAdjust test results (11&12 digits match).
703    
704    checkpoint57t_post
705    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
706    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
707      same truncation, independent of the face number: affects affects several
708      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
709    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
710      note that biharmonic viscosity + no-slip was not tested in any experiment.
711    o fix bug in non-linear free-surf side-drag ; generate new output for
712      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
713    o make mnc honor the writeBinaryPrec flag for most kinds of output
714    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
715    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
716      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
717    o add brackets in multi-terms sum to get same truncation, independent of
718      the face number (manage to get exactly same value of gU,gV at the cs-edge)
719      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
720    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
721      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
722      a maximum grid-scale Reynolds number.  Also, changes all length calculations
723      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
724      Suggested values of viscosity parameters found in mom_calc_visc.
725      Many new viscosity diagnostics available.
726    
727    checkpoint57s_post
728    o Add clearing-house for viscosity calculations, mom_calc_visc and
729      correct numerous bugs in LeithD and Smagorinsky discretizations.  
730      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
731      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
732      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
733      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
734      The Strain-Tension form is now called with useStrainTensonVisc=.true.
735      ViscAhStrain and viscAhTension are now retired.
736    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
737    o In response to JMC's bug report, genmake2 now ignores any soft-links
738      that it finds in the *current* directory when searching for files.
739      Soft-links found in any other source directories will still work as
740      they did before.
741    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
742      a C routine to unlimit the stack size
743    o mnc-ify pkg/aim snapshot vars
744    o mnc-ify pkg/land as requested by Daniel
745    o various changes to mnc including:
746      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
747      - output can now be grouped so that all files within a group
748          change the ITER portion of their names in lock-step together
749      - can now read ("global") PER-FACE (in addition to PER-TILE) files
750          and works with both EXCH1 and EXCH2 (but needs more testing)
751      - writing works for all verification test cases w/ g77 on Linux
752    
753    checkpoint57r_post
754    o make MNC variable initialization happen earlier
755    o add diagnostics for (almost) each term of the momentum Eq.
756    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
757    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
758    o remove MINIMAL_TAVE_OUTPUT option ;
759      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
760    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
761      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
762    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
763    o add time-dependent SST, SSS control
764    o cost terms in ecco/ modularized (new cost_generic.F)
765    o cost_averages routines are modularized (new cost_averagesgeneric.F)
766    o new infrastructure for seaice model vs. obs misfits in seaice/
767      * driver from the_main_loop.F is seaice_cost_driver.F
768      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
769      * gradient check in Exp. 6a of natl_box_adjoint/
770    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
771      (see README file)
772    
773    checkpoint57q_post
774    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
775    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
776      - bug was reported by Jean-Michel and Ian Fenty
777    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
778      update exp. cpl_aim+ocn output.
779    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
780      Needed for high-res. runs with large global files
781      to be able to limit tapelev size
782    o Changed some tests for adjoint:
783      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
784      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
785      * global_ocean.90x40x15/ back to default 3-level checkpointing
786    o Modifications to enable scripted COMMON to MODULE conversion
787      * verification/OpenAD/code/ has necessary scripts and description;
788      * converts, compiles and runs successfully;
789    
790    checkpoint57p_post
791    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
792    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
793      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
794    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
795    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
796      (was already the case for dissipation with mom_vecinv,
797       and also the case for grad.PhiHyd when staggered-timeStep)
798      This will allow to put dissipation out-off the AB time-stepping.
799     Unfortunately, affects truncation error. Update output of exp. that "fails"
800      (cg2d matching number) and leave the others for later: front_relax(10),
801      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
802      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
803    
804    checkpoint57o_post
805    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
806      (2) its ready to be documented during the 20050801 DocFest
807    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
808      for ideal_2D_oce and lab_sea on linux_ia32_g77
809    o set to #undef CTRL_SET_OLD_MAXCVARS_30
810      in global1x1_tot/code_seaice_adj to access indices 32, 33
811      (worth another tag)
812    
813    checkpoint57n_post
814    o adding precip control xx_precip 32
815    o adding swflux control xx_swflux 33
816    o Replacing 10 forcing penalty cost routines by 1 generic.
817    o Implementing partitioning in time-mean and variable adjustment
818      for atmos. state.
819    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
820    o in natl_box_adjoint:
821      * updated exp 1 to 10
822        (but does not have time-mean vs. variable split results yet)
823    o updated global1x1/*_seaice_adj/
824      to incorporate latest changes
825    o enable useSingleCpuIO for mdsio vector routines
826      (applies in particular to tapelev I/O)
827    o removed inefficient K-loop in all active_file*control*.F
828    
829    checkpoint57m_post
830    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
831      and advect_cs (use EXCH-2 and standard cs-32 grid files).
832    o pkg/exch2: filling of face-corner halo regions is optional
833      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
834    
835    checkpoint57l_post
836     tag before updating tutorials (pre-release-2)
837    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
838       for output and interpolation of input fields onto model grid)
839    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
840       Affects results of exp. rotating_tank ; update output.txt.
841    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
842          and taking the square quantity and/or using a fraction-weight field.
843    o fix aim_diagnostics_init.F mate numbers.
844    o add mnc output capability to diagnostics/diagstat and update
845      our cvsignore files for the ACSII output generated
846    
847    checkpoint57k_post
848    o lab_sea now uses diagnostics package and provides a suite of
849      new EXF diagnostics output.
850    
851    checkpoint57j_post
852    o exf
853      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
854        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
855        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
856      * extended diagnostics output
857        - now includes all EXF variables
858        - hs, hl moved to common block
859        - separate S/R for diagnostics, called after ctrl vector is added
860        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
861        - EXFqnet contains true Qnet (i.e. includes qsw)
862      * updated verif. lab_sea, global_with_exf
863      * Rearranging hflux (exf_mapfields -> exf_getforcing)
864        to ensure that diagnostics sees a true EXFqnet
865    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
866    o diagnostics pkg: change pointers so that 1 diagnostic can be used
867      several times with different frequencies.
868    o mnc-ify the thsice package as requested by Daniel Enderton
869      - the monitor--MNC output needs work
870      - many attributes need to be added (most are currently blank)
871    o mnc-ify theaim_v23 package as requested by Daniel Enderton
872      - many attributes need to be added (most are currently blank)
873    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
874    o add Sadourny like discretization to the 4th.O vorticity advection scheme
875    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
876      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
877         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
878    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
879     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
880    
881    checkpoint57i_post
882    o Diagnostics package was changed: diagnostic allocation is now deactivated
883      by setting an empty file name in the namelist (used to be by setting 0 frequency)
884    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
885      add 1rst Order upwind vertical Shear.
886    o add a quick fix for A/B checkpointing in OFFLINE mode
887    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
888      end-run around the C/Fortran linking horror in eesup/src/timers.F
889    o added pkg/runclock: allows user to terminate run based on wall clock
890    o added non-hydrostatic scaling parameter: nh_am2
891    o pkg/my82: futile attempt to make results compiler-independent by adding
892      some "_d 0", etc. no effect.
893    o for mnc output, fill the 'T' coordinate var with myTime and create a
894      separate 'iter' variable for iteration count
895    o pkg/diagnostics:
896      add new capability: output of Global/Regional & per-level statistics ;
897      tested against monitor output (including land & thSIce) on various exp.
898    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
899    
900    checkpoint57h_done
901      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
902      data.diagnostics, data.gchem, data.ptracers) is done.
903    
904    o pkg/diagnostics: prepare for Global/Regional statistics.
905      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
906    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
907      and rename it: DIFFERENT_MULTIPLE
908    
909    checkpoint57h_post
910    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
911    o pkg/diagnostics: change output frequency, now in seconds (instead
912      of Nb of iterations). This requires to change data.diagnostics.
913    checkpoint57h_pre
914    
915    o in mnc, let the user create the output dir if both mnc_outdir_date
916      and mnc_outdir_num are false
917    o add fflags() to pkg/diagnostics which allows one to specify, on a
918      per-file basis, the file precision [default behavior is unchanged]
919    o added diagnostics to pkg/kpp, including computation of mixed layer
920      depth based on a temperature/density criterion
921    o updated verification/natl_box to test the new pkg/kpp diagnostics
922    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
923    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
924    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
925      not mnc -- this mistake was found by JMC and is now corrected
926    
927    checkpoint57g_post
928    o add Adams-Bashforth 3rd Order time stepping:
929      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
930      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
931    checkpoint57g_pre
932    
933    o make lambda[Theta,Salt]ClimRelax spatially varying
934      (default remains spatially uniform constant based on tau)
935    o added new control variables
936      * init. uVel, vVel, etanN
937      * lambda[Theta,Salt]ClimRelax
938    o separate masks used for ctrl_pack/unpack 'from write_grid' output
939      (suggested by G. Forget)
940    
941    checkpoint57f_post
942    o add parameter "baseTime" = model base time = time at iteration zero
943      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
944      account for baseTime shift
945    o move Coriolis arrays from PARAMS.h to GRID.h
946    checkpoint57f_pre
947    
948    o mnc-ifying the seaice package
949    o introduced an alternative length scale calculation for use in the limiting
950      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
951    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
952    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
953      as well as grad(vort3).  Made it compatible with both approximate form
954      for the cubed sphere and full form of these gradients.  Added flag
955      useFullLeith to select between approximate and full form.  
956    o add "d0" in getcon.F to reduce differences between compilers/platforms
957      update output.txt of exp. fizhi-gridalt-hs
958    o change port_rand funtion to allow to set the seed.
959    o fix obscure MNC bug involving conversion between reals and integers
960      - it caused no problems with certain (eg. gcc, ifc) compilers but the
961        new version is now more standards-compliant
962    o adjoint-related modifications
963      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
964      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
965      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
966    
967    checkpoint57e_post
968    o Adding eddy stress controls a la Ferreira et al.
969    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
970    
971    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
972      update output.txt of exp. fizhi-gridalt-hs
973    o add more "Z" dimensions and associated coordinate vars to MNC
974    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
975    o parameter calendarDumps: when set, approximate months (30-31 days) and years
976      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
977      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
978      months and years.  Requires pkg/cal.
979    o diagnostics: add pickup functionality
980      - off by default for backwards compatibility
981      - current version only uses MDSIO -- MNC will be added
982    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
983    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
984    
985    checkpoint57d_post
986    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
987    o modify verification/ideal_2D_oce so that it tests the creation of mnc
988      output from the diagnostics package
989    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
990    o make genmake2 more portable by using ".$FS" instead of ".f" for more
991      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
992    o add coordinate variables to the MNC output from the diagnostics package
993    o change MNC-flags default value: true when useMNC=TRUE
994    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
995      the ability (off by default) to read the grid information using MNC
996    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
997    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
998    o do snap-shot diagnostics at the middle of the time-interval (instead of
999      at the end).
1000    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1001      new test for AIM with thSIce + slab-ocean
1002    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1003    o move state variable diagnostics to the beginning of the time step ;
1004      (note: still needs some work specially for snap-shot diagnostics)
1005      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1006    
1007    checkpoint57c_post
1008    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1009    o generate new output.txt files on faulks with g77 & the new -ieee option
1010    checkpoint57c_pre
1011    
1012    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1013      update output.txt of exp. global_ocean.90x40x15
1014    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1015      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1016    o add saltFlux(+File) forcing capability with periodicExternalForcing
1017    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1018    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1019    o improvements for the MNC output from DIAGNOSTICS:
1020      - correct handling of the unlimitied dimension
1021      - all dims now have associated coordinate variables
1022      - variables located at U, V, and Corner ("Z") points are now written
1023        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1024        *all* data points are output
1025    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1026    o added pkg/seaice/seaice_monitor.F
1027    o mdsio_readfield.F can now read files visible only to master MPI process.
1028    o pkg/seaice: some test code for ice-modified ocean stress
1029    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1030      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1031      spurious negative numbers for precipitation and humidity.  Will cause
1032      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1033    o pkg/ctrl/
1034      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1035        May be enabled via doPackDiag
1036      *  introduce z-scaling of
1037         + gradient (doZscalePack) and
1038         + control (doZscaleUnpack)
1039    o pkg/mdsio/
1040      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1041      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1042    
1043    checkpoint57b_post
1044    o simplify options in diagnostics_fill arguments (remove weird combinations)
1045    o fix MNC coordinate variables so that they now contain per-face index
1046      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1047      general, EXCH2 grids are only aligned to a "local" coordinate system
1048    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1049    o Implement instantaneous output within pkg diagnostics:
1050      setting a negative frequency in data.diagnostics produces
1051     "snap-shot" output (as opposed to time-average if freq > 0)
1052    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1053      NOTE: change ptracer diagnostics name: use 2 characters to work with
1054            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1055    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1056      becomes the coordinate variable for the 'T' dimension
1057    o add CF-style coordinate variables to MNC
1058      - just a first cut:  numbers are meaningless on the cubesphere and
1059        missing along the T axis but otherwise it works!
1060    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1061    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1062    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1063      this is based directly on what the model compute, so that the content of
1064      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1065    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1066    o clean up build options files for SunOS, in particular
1067      - remove -traditional from xmakedepend
1068      - change -xarch=v9 to -xarch=native for f77
1069      - restore use of make (not gmake)
1070      - add CC=gcc if using g77
1071    o changes per discussion of AM, JMC, & EH3 today:
1072      - move redundant "grid" variables out of "state" -- in preparation of
1073        creating proper CF-style coordinate variables and in recognition
1074        that any/all grid variables can be easily copied (eg. w/NCO) from
1075        the grid files into any of the other NetCDF files
1076      - *always* output grid variables with MDSIO (this will eventually be
1077        changed)
1078      - output MNC grid file if useMNC is true
1079    o every instance of _END_MASTER() has been found and replaced with
1080      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1081      preprocessors
1082    o re-arrange diagnostics pkg initialisation:
1083     - allow each package to extend the available diagnostics list
1084     - add some checking and fix small problems (multi-threaded, ...)
1085     - new S/R diagnostics_fill (replace fill_diagnostics):
1086       look through the short list of active diag. (instead of the long list)
1087       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1088    
1089    checkpoint57a_post
1090    o this set of changes restores TAMC compatibility
1091      tested for global_ocean.90x40x15 adjoint on trough
1092      (what a pain)
1093    
1094    checkpoint57a_pre
1095    o some modifs in tools/build_options for sunos
1096    o call ctrl_pack for ctrl at end for optimcycle=0
1097    
1098    checkpoint57
1099    o add horizontal bi-harmonic viscosity for vertical velocity
1100      - new parameter viscA4W (defaults to viscA4)
1101      - affects only non-hydrostatic code
1102      - to be done: no-slip lateral boundary conditions
1103    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1104    o implement Implicit Vertical advection for pTracers
1105    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1106      (implemented also for implicit vertical diffusion & advection)
1107    o OBCS: extend application of tracer open boundary conditions
1108      to a strip beyond the boundary of width Olx/Oly
1109    o add call monitor to TAF set of required calls (flow directives)
1110      and include in natl_box_adjoint
1111    o untangle a few ifdefs related to cost, ctrl, autodiff
1112      untangel a few ALLOW_ECCO_OPTIMIZATION
1113    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1114      (theta2, salt2 in ecco_cost_weights)
1115    
1116    checkpoint56c_post
1117    o OBCS as control variables
1118      - update ctrl_ad_diff.list, obcs_ad_diff.list
1119      - remove balance of obcs controls from default
1120      - fix index bug nobcs in ctrl_init
1121      - fix dummy fields filen in ctrl_pack
1122      - add dummy weights for obcs
1123    o lsopt: comment out fort.94 output
1124    o optim:
1125      - remove unnecessary header files
1126      - adjusted namelists
1127      - add xerbla.F to Makefile
1128    o exf:
1129      - multiple modifications of exf_check_range
1130      - unit change in exf_init_runoff from [m/year] to [m/s]
1131    o mdsio:
1132      - i/o-vector change debugLevel from debLevA to debLevB
1133    
1134    checkpoint56b_post
1135    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1136      is called from DO_THE_MODEL_IO
1137      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1138      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1139      - clean up PTRACERS_WRITE_TIMEAVE a little
1140    o add another verification experiment that tests both the cfc-pkg and
1141      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1142      reactive tendencies treated inline with regular timestepping
1143    o testreport previously did a lousy job of comparing small numbers, so
1144      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1145      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1146      testreport.
1147    o ptracers_monitor: bug fix for MPI
1148    
1149    checkpoint56a_post
1150    o GCHEM: finish reorganizating the package
1151      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1152        (introduces another 3D-array for each passive tracer, but only if
1153        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1154        gchemTendency is not needed because the timestep is done separately)
1155      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1156      - GCHEM is now---more or less cleanly---separate from PTRACERS
1157      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1158        so clear to me how that should be done in a general way.
1159    o CFC: improve formatting of output in CFC_ATMOS
1160    o PTRACERS:
1161      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1162        that ALL experiments with ptracers enable can be checked. This makes
1163        GCHEM_MONITOR obsolete.
1164      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1165        monitorFreq
1166      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1167    o add PTRACERS (PTR0[1-5]) to testreport output
1168    o exf_check_range:
1169      * default changed to .TRUE.
1170      * will check values for niter0 if debLevA, every timestep if debLevB
1171      * STOP in exf_check_range if 'out of range'
1172      * range chosen generous to allow for potential extema
1173      TBD: a version with stricter range
1174           permitted range would be runtime parameters
1175    o GMredi:
1176      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1177      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1178      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1179    o GCHEM:
1180      - move call to GCHEM_FORCING_SEP, so that it is now called before
1181        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1182      - introduced a useGCHEM runtime flag and applied it everywhere.
1183      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1184        this flag is now only visible within GCHEM-pkg routines.
1185      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1186        be replaced by a 3D array that is computed before thermodynamics; for
1187        this, the tracer ID iTracer had to be included into the parameter list
1188        of ptracers_forcing
1189      - set up forward_step to call gchem_forcing, that will replace
1190        gchem_forcing_int in ptracers_forcing
1191      - cleaning up
1192    o small cleaning of exch2: remove files that are also in eesupp/src
1193    
1194    checkpoint56
1195    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1196    o mnc: cleanup "full" files--fixes out-of-memory problem
1197    o ECCO-GODAE
1198      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1199      * fully merged and updated from SIO code
1200        windstress sign change affects
1201        - exf_inscal_[u/v]stress
1202        - sign of xx_tau[u/v] adjustments
1203        - signs in cost_scat
1204      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1205      * natl_box_adjoint updated and compressed
1206      * 2-level checkpoint switch added
1207        (tested in EXP. 1 of natl_box_adjoint)
1208      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1209    o SVD
1210      * first complete, non-hacked version for SVD calculations
1211      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1212        performed via direct access files admtlm_vector.it????
1213        (via ctrl_[un]pack)
1214      * optimcycle is used for ARPACK iteration counter
1215        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1216      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1217        and add linear transforms where necessary
1218      * controls are initial/final SST, SSS (can be extended; need to check
1219        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1220    o mdsio: filename info to both stderr, stdout
1221    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1222      from sign change
1223    
1224    checkpoint55j_post
1225    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1226      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1227    o add consistent build directories and .cvsignore files to verification
1228    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1229    o make all subroutines 30 or less characters in length for certain older
1230      compilers to work (a thorough search only turns up two routines in
1231      pkg/ptracers)
1232    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1233      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1234    
1235    checkpoint55i_post
1236    o change arrays for total vertical diffusivity (2.D if explicit,
1237      3.D if implicit) ; each ptracer uses its own background value.
1238    o added mnc/NetCDF output capability to ocn_compon_interf
1239      - added bits to verification/cpl_aim+ocn so that it can run on
1240        ITRDA and other clusters without the mpirun "-wd" option
1241    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1242      configuration
1243    o give MNC the ability to create additional files rather than
1244      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1245      - the default is just less than 2GB which is a practical limit
1246        on many systems
1247    o Compute the non-local term using either KPP vertical diffusivity (=default)
1248       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1249    
1250    checkpoint55h_post
1251    o add verification test "vermix"
1252    o remove all the *_ioinc flags and replace with the single global
1253      outputTypesInclusive flag
1254    o allow to set a vertical profile of vertical diffusivity for T & S
1255    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1256    o useMNC moved from data.mnc to data.pkg
1257    
1258    checkpoint55g_post
1259    o Renaming carbon AD experiments to comply with testreport conventions
1260    o Updating adjoint of Held-Suarez hs94.1x64x5
1261    o Fixing directives for non-ECCO forward_step, after ECCO directives
1262      have been fixed to avoid recomp. of do_oceanic_phys
1263      Works well for global_ocean.90x40x15,
1264      but recomp. issue remains for carbon
1265    o Updating adjoint output for natl_box_adjoint after
1266      pkg/ecco has been modified (see taga c55d_post)
1267    
1268    checkpoint55f_post
1269    o rename to timeave_init_fixed
1270    
1271    checkpoint55e_post
1272    o some delicate re-shuffle of store directives to avoid one
1273      extra call of do_oceanic_physics
1274      affects ecco_the_main_loop.F, do_oceanic_physics.F
1275      checkpoint_lev1_directives.h
1276    o NB: this may break global_ocean adjoint temporarily,
1277      but it is clear how to fix it. Will do later, need this now.
1278    
1279    checkpoint55d_post
1280    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1281    o ecco_cost_weights is modified to 1x1 runs
1282    o modifs to allow observations to be read in as
1283      single file or yearly files
1284    o enable to read exf forcing fields as either
1285      single file or yearly files (flag useExfYearlyFields)
1286    checkpoint55d_pre
1287    
1288    o switch between 2-level and 3-level checkpointing
1289    o add ability of MNC to write local and "partial" (eg. 2D slices where
1290      the full 3D field is never actually stored) arrays to NetCDF files
1291      with the correct (that is, the complete multi-dimensional) set of
1292      array indicies
1293      - used in mom_vecinv() to write the diagFreq output
1294      - tested (demonstrated) in verification/aim.5l_cs
1295    o further mnc-ification
1296      - add verification/lab_sea to the list with mnc setups
1297      - fix undefined mnc v-names in cd_code
1298      - add kpp to mnc output (both snapshot and timeave)
1299    o non-hydrostatic code
1300      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1301        in calc_gw.F
1302      - defaults to viscAh
1303      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1304        friction or Leith) in non-hydrostatic mode, as long as there is
1305        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1306    o pkg/cost
1307      extend simple cost functions to treat time mean quantities
1308      (T,U,V) via cost_accumulate_state from cost_tile
1309    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1310        be 2 times larger than the minimum size the advection scheme requires.
1311        now get a perfect conservation of salt in advect_cs test-exp (updated)
1312    o GGL90 (Gaspar's TKE mixed layer)
1313      - add horizontal diffusion of TKE, requires exchanges in
1314        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1315        default. In OPA there is no horizontal diffusion of TKE but the
1316        mixing coefficients are computed from a horizontal average of TKE of
1317        6 points or so. I think that diffusion has a little more physical
1318        justification.
1319      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1320        was in vain)
1321      - mask tke-variable in ggl90_init
1322    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1323    o fix biharmonic diffusion on CS-grid.
1324    o more obcs stuff
1325      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1326        for reading boundary values. This routine is called from
1327        obcs_prescribe_read
1328      - updated obcs_check
1329      - changed sponge layer relaxation parameter units for days to seconds
1330      - turned off sponge layer by default
1331      - changed argument list of OBCS_CALC to myTime+deltaTclock
1332      - fixed about 35 bugs in obcs_external_fields_load
1333    
1334    checkpoint55c_post
1335    o obcs stuff
1336      - new runtime flags useOBCSprescribe, useOBCSbalance
1337      - re-arranged obcs_calc
1338      - moved exf_getobcs to obcs_prescibe_read
1339        obcs_prescibe_read is called after ORLANSKI stuff
1340        and independent of it (executable can contain all).
1341      - updated obcs_check
1342      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1343        These may be necessary only if tangential velocities are
1344        prescribed at OB, not sure, needs testing.
1345    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1346      which simplifies the calls and passes the ifc check-bounds test
1347    
1348    checkpoint55b_post
1349    o add a 2D scalar, Z location, exchange_2 routine.
1350    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1351      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1352      affects advect_cs results (for the wrong reason): update output.txt
1353    o use a more standard discretization for biharmonic viscosity ;
1354     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1355      affects results of dome set-up: update output.txt
1356    o fix gad_advection.F (CubedSphere part), back to version 1.23
1357    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1358    
1359    checkpoint55a_post
1360    o merged code to
1361      * prescribe/read time-dependent open boundaries
1362        (works in conjunction with exf, cal)
1363      * sponge layer code for open boundaries
1364      * each boundary N/S/E/W now has its own CPP option
1365        (healthy for the adjoint)
1366    
1367    checkpoint55
1368    o up-to-date adjoint of previous breaks
1369      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1370      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1371      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1372      - carbon: * remove tr1-related adjoint verification
1373                * add ptracer as control variable
1374    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1375      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1376    
1377    checkpoint54f_post
1378    o in verification/carbin/ remove experiment related to
1379      ALLOW_PASSIVE_TRACER (array tr1 etc)
1380      code_ad/ input_ad/ results_ad
1381    
1382    o add two new packages
1383      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1384        + subject to optimization (memory)
1385      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1386        + subject to reordering (many GOTOs in the original code)
1387        + so far opps is called for every (i,j) point, and then operates in
1388          the vertical; one may want to reorder the scheme in order operate in
1389          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1390          fields)
1391    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1392      - all verification tests compile and run with linux_ia32_g77
1393      - defaults are compatible with current input files--nothing
1394        should change if you were not previously using MNC
1395      - MNC output has been added in numerous places (eg. timeave)
1396        but there are still a few writes not yet do-able with MNC
1397        (this is in progress)
1398      - flags now allow for either/or/both use of MDSIO and MNC and
1399        documentation will soon follow
1400      - numerous small formatting cleanups for ProTeX
1401    o add version info (via BUILD_INFO.h) to MNC and stdout
1402    
1403    checkpoint54e_post
1404    o add two new packages
1405      - pp81 (Packanowski and Philander, 1981), Richardson number and
1406        stratification dependent mixing
1407      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1408      - these scheme operate in a similar manner as KPP (without ghat, of
1409        course), however there is only one diffusivity that is used for both
1410        temperature and salinity (and passive tracers)ç
1411    o add offline package
1412    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1413      provided by Stephanie Dutkiewicz
1414    o genmake2: add ability to search for C compilers and cleanup test output
1415      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1416    
1417    checkpoint54d_post
1418    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1419    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1420      leading to additional shift by 5 days each year of integration
1421       (i.e. leading to considerable offset over the years)
1422    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1423    o start with no AB and no initial filtering (staggerTimeStep):
1424      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1425    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1426      (external loading & cpl import/export stay in forward_step.F)
1427    o update coupling interface to work with new staggerTimeStep
1428    o change MDSIO ptracers_pickup.
1429    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1430    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1431    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1432    
1433    checkpoint54c_post
1434    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1435      this affects (truncation error) output.txt of test-exp:
1436       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1437    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1438    o change Qnet to always be the net heat flux, (+upward).
1439      affects (truncation error) output of natl_box exp.: updated
1440    o define the max number of passive tracers in PTRACERS_SIZE.h
1441    o start to test mnc routinely in exp0
1442    o add sea-ice loading (sIceLoad) as a new forcing field.
1443    
1444    checkpoint54b_post
1445    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1446       impressive on Altix and Opteron systems)
1447    o diagnostics can now write NetCDF files through the mnc package
1448    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1449    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1450    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1451      affects (truncation error) output of lab_sea & natl_box exp.: updated
1452    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1453    
1454    checkpoint54a_post
1455    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1456    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1457    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1458    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1459      + internal_wave (shift in writing cg2d_ini_res)
1460    checkpoint54a_pre
1461    
1462    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1463      - modified verification/lab_sea and natl_box_adjoint accordingly
1464    
1465    checkpoint54
1466    checkpoint53g_post
1467    o prepare splitting of thermodynamics: store convect.counter in common block
1468    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1469      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1470    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1471    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1472    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1473    o restore adjointability
1474    
1475    checkpoint53f_post
1476    o modifications that affect AIM experiment results (update output.txt):
1477      - no advection of S at top interface Nr (pkg/generic_advdiff)
1478      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1479    o AIM pkg:
1480      - include stability function into surf.Flux derivative relative to Tsurf
1481      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1482    
1483    checkpoint53e_post
1484    o merged cylindrical coord configuration
1485    o added rotating_tank experiment
1486    checkpoint53e_pre
1487    
1488    checkpoint53d_post
1489    o faulks upgraded: re-generate output.txt that have changed:
1490       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1491    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1492    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1493    o added Sadourny discretization of Coriolis
1494      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1495      - re-enabled use of omega3 (useAbsVorticity)
1496    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1497      vector-invariant equations
1498      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1499    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1500      hopefully without new bugs
1501      - still to do: biharmonic friction for non-hydrostatic w
1502    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1503    o regenerated output for global_ocean_ebm (using -ieee)
1504    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1505      of mom_common/
1506      - simple re-arrangement of instructions within computing loop
1507    checkpoint53d_pre
1508    
1509    checkpoint53c_post
1510    o new version of coupler for AIM+thSIce and Ocean models
1511     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1512     - land: change Evaporation of snow
1513     - aim with thSIce: fix bug in snow-precip.
1514    o changes to calc_gw.F
1515     - bug fix for w^2 term near the bottom boundary
1516     - (hopefully) improve the lateral slip boundary condtions for use with
1517        partial/looped cells
1518      - because the bug fix changes two verification experiments anyway (exp5
1519        and plume on slope), change the lateral boundary condition from half slip
1520        to the value of no_slip_sides
1521    o ebm package wasnt quite up to the parallel task. Fixed that.
1522    o Adjoint of EBM package + verification
1523      * TLM OK
1524      * ADM not sufficient accuracy yet (needs further testing)
1525    
1526    checkpoint53b_post
1527    o Commiting new energy balance model to repository
1528      * package is pkg/ebm
1529      * verif. is verification/global_ocean_ebm
1530      * references are in ebm_driver.F
1531    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1532    C        Global thermohaline circulation. Part I:
1533    C        Sensitivity to atmospheric moisture transport.
1534    C        J. Climate 12(1), 71-82
1535    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1536    C        Global thermohaline circulation. Part II:

1539    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1540    C        Destabilization of the thermohaline circulation
1541    C        by atmospheric eddy transports.
1542    C        J. Climate 7(12), 1870-1882
1543    o Will need long integration testing.
1544    checkpoint53b_pre
1545    
1546    o created pkg/mom_common in preparation for variable viscosity code
1547    o renamed and split ini_mnc_io
1548    o pkg/land: only liquid water can diffuse or run-off
1549    o AIM using land: soil wetness availability account for snow
1550    o added printMapIncludesZeros to EEPARMS namelist
1551    
1552    checkpoint53a_post
1553    o restore TAMC compatiility for exf_constants.h
1554      (no usage of _d in .h)
1555    o Additional storing in KPP in an attempt to fix
1556      TAMC problem with adjoint of KPP code.
1557      (no success...)
1558      Identical code works fine with TAF.
1559    o Fixed verification/natl_box_adjoint experiments.
1560      Initial conditions for Experiments 4 and 5 are now
1561      set to "SEAICE_initialHEFF=0", which is more reasonable,
1562      and hence gives results closer to that of Experiment 2.
1563      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1564    
1565    checkpoint53
1566    o stable checkpoint with up to date adjoint
1567      TLM tests only run for 1st grdchk at the moment. Its unclear if
1568      this is a code problem or a problem with resetting code for g_
1569      variables that is being autogenerated wrong.
1570      Otherwise:
1571       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1572       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1573         are both still in chaos following their security messes.
1574    
1575    checkpoint52n_post
1576    o various build (mostly genmake2) changes including:
1577      - ability to build/run more easily within Cygwin and MacOS X
1578      - more complicated Makefiles with a stronger dependence on Gnu Make
1579    o pkg/seaice modifications
1580      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1581        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1582        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1583      - changed proxy for geostrophic velocity and updated
1584        verification/lab_sea/results/* accordingly
1585      - removed ADI dynamic solver from pkg/seaice
1586      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1587        they caused a segmentation fault under certain circumstances
1588      - removed unused field WATR
1589    o bug fix in exf-package:
1590      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1591         now reflect that.
1592    o small fixes in the cal-package:
1593      - set reference date to first of January for the 'model'-calendar
1594      - failing of cal_CheckDate in cal_FullDate now actually results in a
1595        warning
1596    o small modifications in exf-package to increase flexibility:
1597      - change climtempfreeze from a constant to a runtime parameter that
1598        is specified in data.exf_clim (default = -1.9)
1599      - introduce runtime parameter windstressmax (default = 2.0) that is
1600        specified in data.exf
1601    o fix in pkg/thsice:
1602      - update Evap (Tsf changes) to be consistent with Latent heat flux
1603      - maintain snow precipitation unchanged (even if Tsf >=0).
1604     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1605    
1606    checkpoint52m_post
1607    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1608      this does not change any of the results, because myIter=0 in swfrac always
1609      lead to jwtype=2 (the default anyway), but the call makes little sense
1610      as a default
1611    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1612    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1613      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1614    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1615    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1616    o extending useSingleCpuIO option to work with new exch2 I/O format
1617      - old-style, missing-tile I/O is still accessible by defining CPP
1618        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1619    o monitor package can write to NetCDF files and/or STDOUT
1620    o fix re-definition bug in MNC_GRID_INIT_ALL()
1621    o doc/api_reference added
1622      - a framework for building an API Reference Manual using all
1623        the "protex" comments embedded in the code
1624      - see pkg/generic_advdiff, pkg/mnc for examples
1625    o MNC:
1626      - make myThid the last argument for all subroutines
1627      - new default for the grid files: NO halos
1628      - add useMNC and other run-time flags
1629      - separate per-file-group handling of the unlimited dimension
1630      - early initialization of MNC w/ flags read at the eeboot stage
1631        and lookup tables set in initialize_fixed
1632      - write all MNC output to a freshly-created directory
1633    o thermodynamics sea-ice (thsice) is now tested with testreport.
1634    o test exp. advect_cs: use the standard cs32 grid ; update output.
1635    o Added functionality to grdchk:
1636      pick global i,j,k position (or nearest wet) where to perform check.
1637    
1638    checkpoint52l_post
1639    o new land formulation:
1640      a) use ground enthalpy as prognostic variable to ensure exact
1641         energy conservation.
1642      b) account for water temperature and for latent heat of freezing
1643         in all processes (rain, run-off, ground storage)
1644      c) compute surface and ground temperature implicitly.
1645    o aim_v23 modification for new land model:
1646      a) Treat separately land / ocean / sea-ice surface fluxes
1647         to allow implicit computation of land & sea-ice surface temp.
1648      b) add snow precipitation.
1649    checkpoint52l_pre
1650    
1651    o fix problem (when 1 tile is empty) in min/max monitor.
1652    o fix bug in timeAve (u,vZetatave in common block)
1653    o no restoring terms under ice for pkg/seaice
1654    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1655    o bug fix for pkg/seaice pickups
1656    o change MNC call locations and add coordinate attributes
1657    o mask vorticity at the corner ; affects global_ocean.cs output
1658    o fix ini_curvilinear_grid ; test CS experiments with mpi
1659    o aim.5l_cs: modify sea-ice fraction input file ; update output
1660    o exf: Adding simple range check routine for exf fields after read
1661    
1662    checkpoint52k_post
1663    o removed top-level directory "diags"
1664      - we migrated these functions to pkg/timeave a long time ago
1665    o fixed bug introduced in pkg/monitor
1666    o accuracy ctrlprec = 32 insuffient for gradient checks using
1667      averaged fields (I/O via cost_averages)
1668      -> use ctrl.h in active_file*.F to control I/O precision.
1669    o paramter list of CALL ADTHE_MAIN_LOOP
1670    o added initial do_the_model_io to ecco
1671    o set all ...Freq to zero after cost_final
1672      taveFreq, dumpFreq, pChkptFreq
1673    o MAIN and ECCO differentiability restored
1674    
1675    checkpoint52j_post
1676    o fix nchklev in tamc.h for global_ocean...
1677    o Bringing flow and store directives up-to-date
1678    o Really weird thing!
1679      call do_the_model_io from the_main_loop with parameters
1680      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1681      TAF places a faulty re-call of initialise_varia
1682      after cost_final call which should not be there!
1683    checkpoint52j_pre
1684    
1685    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1686      error messages
1687    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1688    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1689      debug output
1690    o modfied mdsio_writefield.F to handle non-global files under exch2
1691    o update AIM Cubed-Sphere exp (aim.5l_cs):
1692      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1693    o update AIM Equatorial Channel exp:
1694      use standard aim_v23 pkg and change the SST fields to be more realistic.
1695    o globalFile now works with exch2
1696    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1697      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1698    o limit timeave output for hi-res integrations
1699    
1700    checkpoint52i_post
1701    o removed CPP_EEOPTIONS.h from verification/*/code
1702    o updated the tiling for global_ocean_pressure
1703    checkpoint52i_pre
1704    
1705    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1706      the old pkg/aim).
1707    
1708    checkpoint52h_pre
1709    o shortened offending lines in exch2_send_rx?.template
1710    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1711    o genmake2: add build & execute test for NetCDF code
1712    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1713      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1714    o added useSingleCPUIO flag to monitor.F and mon_out.F
1715    o added temporary hack for sea-ice dynamics on the cube:
1716      metric terms are ignored and it is assumed that
1717      there is no sea-ice on cube faces 1, 2, 4, and 5.
1718    
1719    checkpoint52f_post
1720    o added exch2 cube routines to pkg/exch2
1721    o modified hs94.cs-32x32x5 to use it
1722    o added new grid files to hs94.cs-32x32x5
1723    checkpoint52f_pre
1724    
1725    checkpoint52e_post
1726    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1727      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1728    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1729      to work with implicit vertical advection and AB ;
1730    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1731    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1732     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1733    checkpoint52e_pre
1734    
1735    o fix bug in impldiff when Nr=1 or Nr=2.
1736    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1737    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1738    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1739      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1740    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1741    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1742    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1743    
1744    checkpoint52d_post
1745    o re-tiled many expts to allow comparison in multi-processor mode
1746      - updated output accordingly
1747      - changed hs94.128x64x5 to use intial T from file rather than use the
1748        random number generator
1749    o add infrastructure in model routines for fizhi and gridalt packages
1750    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1751    o changes to permit hi-res, cubed-sphere, configuration
1752      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1753      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1754      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1755        of surface winds for the cube
1756      (A verification experiment, based on global_ocean.cs32x15, but with
1757       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1758       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1759       complete with example surface forcing files and matlab scripts to look
1760       at the output and compare it with that of global_ocean.cs32x15.)
1761    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1762       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1763       to conform to the common rule.
1764    o check-in the first version of the coupler + interfaces for multi-components
1765       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1766       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1767       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1768       - ocean and atmos. share the same horizontal grid (no interpolation).
1769       - exchanges between component and coupler is done in forward_step
1770    o new verification experiment, cpl_aim+ocn:
1771       coupled ocean - AIM atmosphere on cs32 grid.
1772    
1773    checkpoint52d_pre
1774    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1775    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1776    
1777    checkpoint52c_post
1778    o Fixing OPTIONS files for use of exf:
1779      - ALLOW_ECCO not needed
1780      - ECCO_CPPOPTIONS.h should not be included from
1781        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1782        as has been the case in the past
1783      - All cal/exf related options are currently set in
1784        single header file. Should remain so until we
1785        agree on a consistent new policy.
1786    o Removed all CPP options for cal package.
1787      cal has no more CPP options.
1788    o modified STOREs in GAD_ADVECTION
1789    o corrected key comp. for passkey
1790    
1791    checkpoint52b_post
1792    o new version: "thsice" of thermodynamic sea-ice pkg:
1793     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1794     - modify fluxes but do not change theta directly;
1795     - light cleaning of bulk_force pkg (still needed with thsice).
1796     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1797       + output_thsice.txt to test thsice & bulk_force pkgs.
1798    o put back grid & coriolis monitor output.
1799    checkpoint52b_pre
1800    
1801    o call "do_the_model_io" at the beginning (=> dump initial state)
1802    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1803    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1804      (need info on NUMBER_OF_PTRACERS)
1805    o missing PTRACERS headers in some routines
1806    o default tamc.h in pkg/autodiff supposed to crash
1807      to ensure proper customization
1808    
1809    checkpoint52a_post
1810    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1811      - moved surfaceTendencyTice from pkg/seaice to main code
1812      - subroutine FREEZE_SURFACE now limits only surface temperature
1813        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1814        => new output.txt for global_ocean.cs32x15 & global_with_exf
1815      - keep the old version of FREEZE for backward compatibility;
1816        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

1827    checkpoint52 = ecco_c52_e35
1828    o after testing adjoints of checkpoint51u_post
1829    
1830    checkpoint51u_post
1831    o this is the post-merge tag of the ecco-branch
1832      (needs another clean checkout and re-testing)
1833    o various natl_box_adjoint configs and results
1834      but no input fields

1843    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1844    
1845    checkpoint51t_post
1846    o this is the pre-merge tag of the ecco-branch
1847    
1848    checkpoint51s_post
1849    o cleanup: removed various obsolete #define-s
1850    o pkg/grdchk
1851      - renamed 'ph-grd 3' to 'grad-res'
1852      - merged from ecco-branch
1853        (remaining bug fixes for obcs gradient checks)
1854      - additional high-precision output for testreport
1855        (grep for 'precision_grdchk_result')

1878    checkpoint51p_post
1879    o create initial cd_code package
1880      - WARNING: the initialization of fields within packages
1881        is broken because INI_FIELDS (where READ_CHECKPOINT is
1882        called) is called *before* PACKAGES_INIT_VARIABLES.
1883        This seems to be backwards since
1884        1) its important to initially zero the entire field including
1885           the "halo" region
1886        2) zeroing needs to be done *before* reading pickup info
1887           and the pickup call might or might not happen in any
1888           particular run
1889      - this needs an overhaul for R2
1890    o cleanup verification/*/code/GMREDI_OPTIONS.h

1925      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1926      - subroutine FREEZE now limits only surface temperature
1927        (this means new output.txt for global_ocean.90x40x15,
1928         global_ocean.cs32x15, and global_with_exf)
1929    o added surface flux output variables to TIMEAVE_STATVARS

2022      - See verification/global_with_exf/README for usage example.
2023      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
2024        flags and modified pkg/seaice accordingly.
2025    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
2026        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
2027        non-local transport term.
2028    
2029    checkpoint51e_post
2030    o pkg/mom_vecinv:
2031      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)

2056      - debLevB: equivalent to current debugMode=.TRUE.
2057    o introducing pathname variable mdsioLocalDir for mdsio
2058      that can be specified at runtime
2059      (relevant for cluster I/O to local disk)
2060    `
2061    >>>checkpoint51b_post
2062    adjoint of ptracers

2069    o added verification for adjoint with ptracers
2070      - adm. grdchk fail so far
2071      - tlm. grdchk OK
2072      - checked tapelev/comlev recomputations: OK
2073    <<<checkpoint51b_pre
2074    
2075    checkpoint51a_post
2076    o added code for biogeochemistry package
2077      - new pkgs: dic, gchem
2078      - new subroutine in ptracers
2079    o modify code for biogeo packages
2080      - in model/src and pkg/ptracers
2081    
2082    checkpoint51
2083    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
2084      - autodiff, ctrl, exf, grdchk, seaice
2085      kept separate packages
2086      - cost, ecco, obcs
2087    o updating verification/internal_wave, verification/lab_sea
2088      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
2089    
2090    checkpoint50i_post
2091    o Preparing next differentiable checkpoint and sync
2092      of MAIN vs. ecco-branch
2093      - 1st step: this one is differentiable
2094      - 2nd step: next(! not this) checkpoint will have updated packages
2095                  from ecco-branch)
2096    
2097    checkpoint50h_post
2098    o new package "land": provide surface BC for AIM.
2099    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
2100    o AIM: use true log-P extrapolation for near surface temp (= as in
2101        F.Molteni paper) ; update aim.5l_cs output.
2102    o New variable in PARM03 for more flexible pickups
2103    o somewhat cleaned package initialisation sequence for
2104      ctrl/ cost/ ecco/ in packages_... routines
2105    
2106    checkpoint50g_post
2107    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
2108      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
2109      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
2110        made the default because of faster convergence than ADI
2111    
2112    checkpoint50f_post
2113    o exf totally restructured
2114      - replaced all exf_set_ routines by one generic exf_set_gen.F
2115        and made sure it's still differentiable
2116      - split exf_getffields.F into new exf_bulkformulae.F
2117      - exf_inscal_/exf_outscal_ suffixes consistent with field names

2129    
2130    checkpoint50e_post
2131    o make KPP work with PTRACERS
2132     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
2133       nearly a copy of kpp_transport_s
2134     - there is no analogue to SurfaceTendencyS, so I have to use
2135       gPtr(of the surface layer) instead
2136    o add a new platform SunFire+mpi (SunFire 15000) to genmake
2137    checkpoint50e_pre
2138    
2139    checkpoint50d_post
2140    o change kpp output from multiple-record state files to single-record state
2141      files analogous to write_state.F
2142    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
2143      analogous to the cg2d-related output.
2144    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
2145      so that writing to internal file fn (with length 512) fails.
2146    checkpoint50d_pre
2147    
2148    checkpoint50c_post
2149    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
2150    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
2151    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
2152    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
2153    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
2154    
2155    checkpoint50c_pre
2156    Merging from release1_p13:
2157    o bug fix for pkg/seaice dynamic solver
2158    o Added SEAICE_initialHEFF to pkg/seaice
2159    
2160    checkpoint50b_post
2161    o store u*,v* in gU,V instead of in guNm1,gvNm1
2162    o in order to put the momForcing out of the Adams-Bashforth:
2163      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
2164      to timestep.F
2165    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
2166    o re-generate output for highly sensitive test-exp:
2167       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
2168    
2169    checkpoint50b_pre
2170    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
2171    o corrected CPP option mismatch in exf_Bulk... functions for case
2172      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
2173    
2174    checkpoint50a_post
2175    o Bug fix for merging between c50 and KPP.
2176      ikey was passed from thermodynamics to kpp_calc via
2177      common block rather than being recomputed in kpp_calc,
2178      in contradiction with new key itdkey.
2179      New key ikppkey created, and tamc.h headers updated.
2180    
2181    checkpoint50
2182    - 2nd step of merge with ecco-branch:
2183      merge changes in ecco-branch back into main trunk
2184    - bug fix in find_alpha
2185    - more storing in gmredi_calc_tensor.F, kpp_routines.F
2186    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
2187    - merged some sliced AD support routines
2188    
2189    checkpoint49
2190    merged from ecco-branch:
2191    o exf:
2192      - Enable initialisation of forcing fields to constant
2193        (runtime) values.
2194      - in exf_getffields.F
2195        Reduce i-/j-loop to interior domain, discarding overlaps.
2196        That also fixes wrong TAF-key computations for key_1, key_2
2197        with bulf formulae.
2198      - exf_init.F modify #ifdef for exf_init_evap
2199      - exf_getffieldrec.F, ctrl_getrec.F
2200        The following INT-usages are not safe:
2201          fldsecs  = int(fldsecs/fldperiod)*fldperiod
2202          fldcount = int(fldsecs/fldperiod) + 1
2203        and were modified.
2204    o autodiff: checkpoint_lev...
2205      - updated storing for bulk formulae (some arrays were missing)
2206      - added state for seaice package
2207      - synchronized with main branch
2208    o DIVA:
2209      Modif.s in
2210      - the_main_loop.F
2211      - the_model_main.F
2212      and added cost_final_restore.F cost_final_store.F
2213      o With these changes, it is possible to fully separate
2214        the first forward run to compute the cost function (mdthe_main_loop)
2215        and adjoint runs over individual DIVA intervals (adthe_main_loop)
2216        into separate model executions.
2217        This enables better tuning of DIVA to given queue sizes.
2218      o Loss of cost function value in consecutive DIVA runs is
2219        fixed by storing to 'costfinal' file.
2220      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
2221        beginning/end of adjoint integration is accounted for.
2222      The current changes apply to TAF-1.4.26.
2223      TAF has one remaining bug, requiring one manual change
2224      (see MITgcm manual).
2225    o cal: synchronized between MAIN and ecco-branch
2226    
2227    checkpoint48i_post
2228    o Changes to restore differentiability of code w.r.t. previous tag
2229      (mostly adding new routines to make list and replacing
2230      pressure by totPhiHyd).
2231    o Updated and merged grdchk package
2232      - has both ADM and TLM checks
2233      - works for single- and multi-proc.
2234      - output cleaned
2235      - worked successfully for parallel DIVA
2236    o genmake:
2237      - Adding -platform=SP4
2238      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
2239    o Modif. for DIVA:
2240      ctrl_unpack should not be called in intermediate DIVA interval.
2241      (similar thing would apply for active files such as
2242      tbar, sbar, psbar, which should not be reinitialised;
2243      only relevant for ecco-branch)
2244    
2245    checkpoint48h_post
2246    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
2247    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
2248    o Added SEAICE_initialHEFF to pkg/seaice
2249    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
2250    
2251    checkpoint48g_post
2252    --- EOS:
2253    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
2254      store total Potential in totPhyHyd for diagnostics & EOS.
2255    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
2256    --- Pressure/geopotential gradient:
2257    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
2258    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
2259      ( changes results of global_ocean_pressure )
2260    o NLFS + z-coord.: add eta*Rho' contribution.
2261    o accurate phiHyd when using interface-W at the middle between 2 centers
2262     ( changes results of ideal_2D_oce )
2263    o includes r* 2nd term in potential gradient.
2264    
2265    checkpoint48f_post
2266    Merging from release1_p12:
2267    o Modifications for using pkg/exf with pkg/seaice
2268      - improved description of the various forcing configurations
2269      - added basic radiation bulk formulae to pkg/exf
2270      - units/sign fix for evap computation in exf_getffields.F
2271      - updated verification/global_with_exf/results/output.txt
2272    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
2273      (SBO) core products, including oceanic mass, center-of-mass,
2274      angular, and bottom pressure (see pkg/sbo/README.sbo).
2275    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
2276      to avoid negative values in shallow regions.
2277      - updated verification/natl_box/results/output.txt
2278      - updated verification/lab_sea/results/output.txt
2279    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
2280    o Added useSingleCpuIO option (see PARAMS.h).
2281    o Updated useSingleCpuIO option in mdsio_writefield.F to
2282      work with multi-field files, e.g., for single-file pickup.
2283    o pkg/seaice:
2284      - bug fix in growth.F: QNET for no shortwave case
2285      - added HeffFile for specifying initial sea-ice thickness
2286      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
2287    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
2288      kpp_transport_t.F, forward_step.F, and the_main_loop.F
2289    o pkg/seaice:
2290      - adjoint-friendly modifications
2291      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
2292    
2293    checkpoint48e_post
2294    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
2295    o dynamics: change definition of computational domain & adapt mom_fluxform
2296      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
2297    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
2298        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
2299        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
2300        global_ocean.90x40x15 global_with_exf global_ocean_pressure
2301        inverted_barometer solid-body.cs-32x32x1
2302      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
2303    
2304    checkpoint48d_post
2305    o in preparation for r*:
2306     a) use pre-computed gradient of hydrostatic potential:
2307        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
2308     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
2309        => affects results of glob_oce_pressure (different truncation error)  
2310      update output.txt of ideal_2D_oce & global_ocean_pressure
2311    
2312    checkpoint48d_pre
2313    o in preparation for r*:
2314      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
2315      pass the 2 comp. of the grad. as arguments to momentum S/R.
2316      but for the moment, only used if it does not change the results.
2317    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
2318    
2319    checkpoint48c_post
2320    Modifications in treatment of initial flux forcing controls
2321    to avoid extra storing of flux fields.
2322    
2323    checkpoint48c_pre
2324    o Added tidal_basin_2d experiment (currently 1D!)
2325    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
2326    
2327    checkpoint48b_post
2328    o r* coordinate added in #ifdef NONLIN_FRSURF block.
2329     (modification to pressure gradient not yet implemented)
2330    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
2331      (for U & V) that are used for vertical advection of momentum.
2332    
2333    checkpoint48a_post
2334    o In preparation for r*, use temp. array to compute vertical transport
2335       in flux-form momentum pkg. => change results of few test-exp.
2336      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
2337                        lab_sea, natl_box & plume_on_slope
2338    
2339    checkpoint48
2340    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
2341    
2342    checkpoint47j_post
2343    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
2344    o moved adexch from forward_step to addummy_in_stepping
2345    o added exch in ctrl_map_...
2346    o aveFreq.=0. at end of cost_final to avoid overwrite in
2347      reverse checkpointing loop
2348    o Yet more changes in gmredi:
2349      * adgmredi_calc_tensor
2350        avoiding all recomputation of gmredi_slope_limit
2351      * adgmredi_x/y/rtransport
2352        added flag for excessive storing to avoid recomp. of
2353        u/v/rtans, dTdx/y/z
2354        -> this is not really necessary and very memory-consuming
2355      * adgmredi_slope_psi:
2356        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
2357      * gmredi_slope_limit
2358        re-activated full calculation of taperfct for case 'ac02'
2359    o updating verification/ adjoints of carbon, global_ocean.90x40x15
2360    
2361    checkpoint47i_post
2362    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
2363    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
2364      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
2365    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
2366    o gmredi: fix few bugs.
2367    
2368    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
2369    This will be a good checkpoint to plug into the ecco-branch.
2370    o few modif.'s to get latest version adjointed
2371      (mainly kick out code in ini_linear_phisurf)
2372    o modif's to run adjoint with exactConserv
2373    o case GM_BOLUS_ADVEC should be cleaned
2374      S/R gmredi_slope_psi should be cleaned
2375    o verification/carbon now has exactConserv=.TRUE.
2376    
2377    checkpoint47g_post
2378    o time-average AIM output: becomes independent from statvars time-average
2379      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
2380    o After TAF bug fix:
2381      Tested adjoint of gmredi package.
2382      Tests were done with checkpoint47 rather than with latest
2383      checkpoint47f_post since the latter is broken for the adjoint
2384      verification/carbon/ contains both ADM and TLM gradient checks.
2385    Here they are, before they get changed/lost/stolen.
2386    Mostly modif.'s to fix numerical sensitivities.
2387    Gradient checks OK for
2388    - GM_taper_scheme:
2389      * clipping
2390      * ac02
2391      * linear
2392      * glw91
2393      * dm95
2394      * ldd97
2395    - GMREDI_OPTIONS:
2396      * GM_VISBECK_VARIABLE_K
2397      * GM_NON_UNITY_DIAGONAL
2398      * GM_EXTRA_DIAGONAL
2399      * GM_BOLUS_ADVEC
2400    in conjunction with data.gmredi parameters to be checked in
2401    in a few minutes under verification/carbon/code/
2402    
2403    checkpoint47f_post
2404    Merging from release1_p10:
2405    o modifications for using pkg/exf with pkg/seaice
2406      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
2407        and SEAICE_EXTERNAL_FLUXES
2408      - pkg/exf CPP options EXF_READ_EVAP and
2409        EXF_NO_BULK_COMPUTATIONS
2410      - usage examples are Experiments 8 and 9 in
2411        verification/lab_sea/README
2412      - verification/lab_sea default experiment now uses
2413        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
2414    
2415    checkpoint47e_post
2416    o created a tag prior to creating a branch
2417    
2418    checkpoint47d_post
2419    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
2420      at the bottom boundary had an erroneous half slip boundary condition
2421    o added bottom drag and no slip boundary condition capabilities to
2422      oceanic pressure coordinates code
2423    o added new verification experiment global_ocean_pressure, this experiment is
2424      also described in the tutorial section of the manual
2425    checkpoint47d_pre
2426    
2427    checkpoint47c_post
2428    o Added a verification experiment for a global cubed-sphere ocean run
2429      -  verification/global_ocean.cubed32x32x30
2430      -  uses pkg/therm_seaice and pkg/bulk_forcing
2431    
2432    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
2433    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
2434      when using P-coordinate; only implemented for atmospheric config.
2435    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
2436      NOTES: requires option NONLIN_FRSURF to be "#define".
2437    o update advect_xz/results/output.txt (left from checkpoint44g_post)
2438    
2439    checkpoint47b_post
2440    Merging from release1_p9:
2441    o pkg/seaice
2442      - removed GOTO's and added taf directives
2443      - double precision constants to reduce the g77 (Linux)
2444        to F77 (SGI) differences reported in release1_p8
2445    o tools/genmake
2446      - added SGI options
2447    o verification/testscript
2448      - updated to that of checkpoint47a_post
2449    o verification/global_ocean.90x40x15/input/eedata
2450      - modified for SGI f77 compatibility
2451    o verification/lab_sea
2452      - added description of sea-ice model
2453      - added missing matlab routines
2454      - added test of thermodynamics parallelization
2455    
2456    checkpoint47a_post
2457    o new pkg: aim_v23
2458     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
2459       for now, keep the same surface forcing as before.
2460     - Part-Cell implemented into AIM; check that Heat & Water are conserved
2461     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
2462     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
2463    o add diagnostic of surface correction term in monitor output
2464    
2465    o bulk_force and therm_seaice
2466    - Two packages:  bulk_force (Bulk forcing)
2467      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
2468    - Earlier integration from Stephaine Dutkiewicz
2469      and Patrick Heimbach.
2470    - Two ifdef statements for compile time,
2471       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
2472    
2473    checkpoint47
2474    differentiable version of checkpoint46n_post
2475    o bug fix in quasihydrostaticterms
2476    o * "clean" adjoint code (in terms of extensive recomputations)
2477        can now be obtained for all GMREDI options (i.e. for
2478        - GM_VISBECK_VARIABLE_K
2479        - GM_NON_UNITY_DIAGONAL
2480        - GM_EXTRA_DIAGONAL
2481        - GM_BOLUS_ADVEC )
2482      * However, wrong gradient check problem remains unsolved.
2483      * New CPP options have been introduced for different
2484        tapering schemes
2485    o external_fields_load now part of differentiation list
2486    o pressure needs multiple storing;
2487      would be nice to have store_pressure at beginning or
2488      end of forward_step, e.g. by having phiHyd global (5-dim.)
2489      (NB: pressure is needed for certain cases in find_rho,
2490      which is also invoked through convective_adjustment).
2491    o recomputations in find_rho for cases
2492     'JMD95'/'UNESCO' or 'MDJWF' are OK.
2493    o #define ATMOSPHERIC_LOADING should be differentiable
2494    o ini_forcing shifted to begining of initialise_varia
2495    o Incorporating QNVS line search routines into MITgcm
2496      (this is separate code, and therefore not under pkg)
2497      lsopt/, optim/
2498    o Updated verification/carbon/
2499      - #define GM_VISBECK_VARIABLE_K
2500      - GM_taper_scheme    = 'ldd97'    
2501    
2502    checkpoint46n_post
2503    Merging from release1_p8:
2504    o verification/natl_box:
2505      updating new external_fields_load routine
2506    o New package: pkg/seaice
2507      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
2508      The sea-ice code is based on Hibler (1979-1980).
2509      Two sea-ice dynamic solvers, ADI and LSR, are included.
2510      In addition to computing prognostic sea-ice variables and diagnosing
2511      the forcing/external data fields that drive the ocean model,
2512      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
2513      The implied surface heat flux is then stored in variable
2514      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
2515      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
2516      non-local transport term.  Because this call precedes model
2517      thermodynamics, temperature under sea-ice may not be "exactly" at
2518      the freezing point by the time theta is dumped or time-averaged.
2519      N.B.: fairly large differences in accuracy occur across
2520            different platforms/compilers; comparison between
2521            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
2522            generated output gives:
2523       T           S           U           V
2524      C D M    c        m  s        m  s        m  s        m  s

2528    
2529      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
2530    o GAD:
2531      - generated new common blocks to account for call of
2532        same gad routines with differing traceridentities
2533        (needed to modify tracerIdentity indices in GAD.h)
2534      - generated separate common blocks for case useCubedSphereExchange
2535        (Department of Futurology)
2536      - parameter lists to gmredi_?transport: added tracerIdentity
2537      - added new key indices to tamc.h
2538    o external_fields_load:
2539      - added this routine to TAF list
2540      - needed to make some common blocks global and additional storing
2541        along the same lines as exf package (checkpoint_lev?_directives.h)
2542    o exf:
2543      updated external forcing package
2544      - bug fixes carried over from ecco-branch
2545        (missing OBCS_OPTIONS.h in two routines)
2546      - enable easy to use "no forcing".
2547      - added exf I/O for atmospheric loading
2548      - added exf I/O for runoff data
2549      - transfered scaling between exf <-> MITgcm to exf namelist
2550    o Adding new verification experiment global_with_exf.
2551      This verification experiment is almost identical to the
2552      global_ocean.90x40x15 experiment, except that it uses
2553      the exf (and cal) package instead of the
2554      external_fields_load routine (cf README file).
2555    
2556    checkpoint46m_post
2557    o modified testscript to return -- when there are no lines of "%MON" output
2558    o added new flag "quasiHydrostatic" for QH mode
2559      and new routine quasihydrostaticterms()
2560    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2561      New routine: mom_u_coriolis_nh()
2562    o fixed sign of non-hydrostatic metric terms in u and v equations.
2563      Depend on correct sign of gravitySign.
2564    o added work.pc* to .cvsignore in aim directories using ifc
2565    o introduced flag for controllin non-hydrostatic metric terms
2566    o removed gravitySign from PARM04
2567    o switched to g77/ifc from pgf77 in aim experiments
2568    
2569    checkpoint46l_post
2570    o made convective adjustment work with pressure coordinates:
2571     - changed the direction of k-loop in convective_adjustment.F for the
2572       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
2573     - adjusted the reference pressure k-index in convective_adjustment.F
2574     - adjusted the convection condition in convect.F (in analogy to
2575       calc_ivdc.F)
2576     - convective_adjustment no longer computes anything on the halos
2577     - removed the warnings about negative salinity from find_rho.F and
2578       find_alpha.F; instead the new routine look_for_neg_salinity, called
2579       at the beginning of find_rho, find_alpha, and find_beta, does a
2580       check of the entire slice, if CPP-option
2581       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
2582    checkpoint46l_pre
2583    
2584    checkpoint46k_post
2585    o fixed the verification/global_ocean.90x40x15 experiment:
2586     - new bathymetry (the world according to A., JMC, and M.)
2587     - new initial fields and forcing fields (*.bin files)
2588     - new POLY3.COEFFS (for the next release one should switch to a full
2589       equation of state: JMD95P or MDJWF)
2590     - fixed several errors and redundancies in the data file
2591     - experiment uses looped cells
2592     - added matlab directory with diagnostic scripts for plotting of output
2593    
2594    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
2595     - read AIM physics parameters from a file (data.aimphys)
2596     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
2597    
2598    checkpoint46j_post
2599    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
2600    o move wVel computation at the end of the time step, in S/R integr_continuity
2601    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
2602    o update timeave pkg for wVel diagnostic.
2603    checkpoint46j_pre
2604    
2605    checkpoint46i_post
2606    o Clean up AIM package (and keep the results unchanged):
2607      include CPP_OPTION and use IMPLICT NONE in all routines ;
2608      declare all the variables _RL ; use _d 0 for all numerical constants.
2609      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
2610    
2611    checkpoint46h_post
2612    o cleaned up the use of rhoNil and rhoConst.
2613      - rhoNil should only appear in the LINEAR equation of state, everywhere
2614        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
2615        and the dynamical equations are all divided by rhoConst
2616    o introduced new parameter rhoConstFresh, a reference density of fresh
2617      water, to remove the fresh water flux's dependence on rhoNil. The default
2618      value is 999.8 kg/m^3
2619    o cleanup up external_forcing.F and external_forcing_surf.F
2620      - can now be used by both OCEANIC and OCEANICP
2621    checkpoint46h_pre
2622    
2623     Added code to convert surface volume flux (fresh water) into
2624     a mass flux when using P coordinates in the ocean (OCEANICP).
2625     Note: It assumes you have set rho0=rhoConst=density of fresh water.
2626    
2627    checkpoint46g_post
2628    o Include a new diagnostic variable phiHydLow for the ocean model
2629      - in z-coordinates, it is the bottom pressure anomaly
2630      - in p-coordinates, it is the sea surface elevation
2631      - in both cases, these variable have global drift, reflecting the mass
2632        drift in z-coordinates and the volume drift in p-coordinates
2633      - included time averaging for phiHydLow, be aware of the drift!
2634    o depth-dependent computation of Bo_surf for pressure coordinates
2635      in the ocean (buoyancyRelation='OCEANICP')
2636      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2637        Theta, Salinity, and Pressure in the parameter list. This routine is
2638        presently contained in find_rho.F. This routine does not give the
2639        correct density for 'POLY3', which would be a z-dependent reference
2640        density.
2641    o cleaned up find_rho
2642      - removed obsolete 'eqn' from the parameter list.
2643    o added two new verification experiments: gop and goz
2644      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2645    checkpoint46g_pre
2646    
2647    checkpoint46f_post
2648    o Enable tangent linear (forward mode) gradient checks:
2649      - extended active file handling to g_... files
2650      - added TANGENT_SIMULATION to theSimulationMode
2651      - extended grdchk package accordingly
2652    o added tangent linear setup in verification/carbon/code_ftl
2653    o added adjoint setup in verification/front_relax/code_ad
2654    
2655    checkpoint46e_post
2656    o Added new equation of state -> MDJWF
2657      - EOS of McDougall et al., 2002, JAOT, submitted
2658      - caveat: the equation of state is only valid for a smaller (more
2659        realistic?) range of values than JMD95P/Z and UNESCO
2660      - added masks to the calculation of pressure in store_pressure
2661      - added more check values for density in check_eos (ini_eos.F), some of
2662        the old check values are out of the range of the MDJWF-eos, so don't
2663        expect perfect matches for those
2664    checkpoint46e_pre
2665    
2666    checkpoint46d_post
2667    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2668      'OCEANICP', also initialised field pressure correctly in ini_eos in the
2669      case of pressure coordinates. eosType='JMD95Z' in
2670      combination with buoyancyRelation='OCEANICP' now causes an error.
2671    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2672      in find_alpha/beta.
2673    checkpoint46d_pre
2674    
2675    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2676      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
2677    
2678    checkpoint46c_post
2679    o Changes necessary for ocean in p-coordinates
2680     -  Added new buoyancy relation = 'OCEANICP'
2681     -  Added new parameters = gravitySign (this used to be contained inside
2682        the factor dRdZ which I added when we first switched to R coordinates).
2683     X GM/Redi is not compatible (yet)
2684     X bottom drag and no-slip need to be debugged.
2685    checkpoint46c_pre
2686    
2687    checkpoint46b_post
2688    o Added new equation of state -> JMD95Z and JMD95P
2689      - EOS of Jackett and McDougall, 1995, JAOT
2690      - moved all EOS parameters into EOS.h
2691      - new routines ini_eos.F, store_pressure.F
2692    o Added UNESCO EOS, but not recommended because it requires
2693      in-situ temperature (see JMD95)
2694    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2695      unesco.f to be used with POLY3
2696    checkpoint46b_pre
2697    
2698    checkpoint46a_post
2699    o Added (atmospheric) pressure loading
2700      - new field in FFIELDS.h, etc...
2701      - new cpp flag ATMOSPHERIC_LOADING
2702    o Changed hFacC to _hFacC in calc_phi_hyd.F
2703    o Added SHORTWAVE_HEATING to some files for consistency
2704    checkpoint46a_pre
2705    
2706    checkpoint46
2707    further merges from release1_p5
2708    o new ctrl package
2709      - adopted from ECCO environment to enable optimization
2710      - added Eliassen Palm fluxes to controls
2711    o added Eliassen Palm flux controls to gradient check package
2712    o cost package
2713      - Compatible with new ctrl package
2714      - added Eliassen Palm cost hooks
2715      - modif's of existing cost functions
2716    o Adjoint-related bug fixes in kpp:
2717      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
2718      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
2719    o autodiff package
2720      - flow directives:

2730    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
2731    o incorporated hooks for sponge layer code (external_forcing.F)
2732    
2733    checkpoint45d_post
2734    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2735    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2736      (affects plume_on_slope "cg2d" output)
2737    o add new parameter deltaTfreesurf for free-surface time stepping
2738    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2739    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
2740    o change phiMin in exp1 (to agree with documentation)
2741    o add new flags:
2742     - T,S forcing inside/outside Adams-Bashforth
2743     - turn off temp,salt advection and/or forcing
2744     - for each tracer, define internal flag for multiDimAdvection & A-B

2746    
2747    checkpoint45c_post
2748    o Removed f90 comments ("!")

2752      - enable centered differences
2753      - modified format of standard output
2754    
2755    checkpoint45b_post
2756    o cleaned exchange calls in cg2d
2757    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
2758    o included CPP option SINGLE_LAYER_MODE in thermodynamics
2759      to configure barotropic setup (Martin Losch)
2760    o moved some initialisations within bi,bj loop in dynamics
2761      (TAF flow dependency)
2762    o in initialise_varia, moved call packages_init_variables
2763      before convective_adjustment_init
2764      (corresponding adjustment of TAF tape initialisation).
2765    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
2766    
2767    checkpoint45a_post
2768    o compute Rho over the whole domain (extend iMin,jMin indices)
2769    o specific exchange for X-slice domain (case Ny=1)
2770    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
2771    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
2772    
2773    checkpoint44h_post = checkpoint45
2774    o Fix to restore differentiability:
2775      place at which packages_init_variables is called in
2776      initialise_varia is crucial for reverse control flow.
2777    o modifications in GMRedi to enable stable adjoint
2778      (corresponding modif's in thermodynamics, dynamics)
2779    o added missing hook for sponge layer code in external_forcing

2785    o modified carbon verif.
2786    
2787    checkpoint44h_pre
2788    o vertical grid option: allow to put the Interface at the middle between
2789      2 cell-centers ; replace delZ in pkg/kpp by drF.
2790    o GM Advective form: Tracers are advected using the residual transport (=
2791      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
2792    
2793    checkpoint44g_post
2794    o fix surface correction term in multiDimAdvection (affects plume_on_slope
2795      results) ; ifdef missing in thermodynamics.F
2796    
2797    checkpoint44f_pre,checkpoint44f_post
2798    o added PTRACERS package
2799      This allows an arbitrary number of passive tracers to be integrated
2800      forward simultaneously with the dynamicaly model.
2801      + Implemented so far:
2802        - basic forward algorithm (time-stepping, advection, diffusion, convection)
2803        - I/O and checkpointing
2804        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
2805      + Not implemented so far:
2806        - KPP
2807        - OBCS
2808      + No specific example supplied (yet) but global_ocean.90x40x15 has the
2809        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
2810        line in data.pkg.
2811      + This package is disabled by default since it increases storage.
2812    
2813    
2814    o testscript: added -cleanup option
2815    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

2817    
2818    checkpoint44e_pre,post
2819    o re-wrote convective adjustment to use pre-calculated weights
2820      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
2821      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
2822      Original calls to convect() still in place.
2823    
2824    chkpt44d_pre,post
2825    o added missing EXCLUDE_MONITOR flags
2826    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
2827      (incompatible typ in MIN/MAX expressions caused problems
2828      on IBM SP3)
2829    o in genmake added variable MAKEDEPEND
2830      plus resetting for case SunOS
2831    o added timer_stats.c routine for IBM SP3
2832    o removed variables in dynamics
2833    !!! I forgot to create tag chkpt44d_pre !!!
2834    !!! But chkpt44d_pre = chkpt44c_post    !!!
2835    
2836    o real fresh water flux implemented with non-linear free-surface.
2837    
2838    chkpt44c_pre,post
2839    o few fix (mask in shap_s2, EmPmR in external_field_load,
2840      USE_NATURAL_BCS in solve_for_P);
2841    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
2842    
2843    checkpoint44b_pre/_post
2844    o merge of relevant stuff from the ecco-branch:
2845      - genmake: removed $S64 overwrite for case SunOS
2846      - pkg/exf: update and corrections for field swapping and obcs

2848                  harmonized between ECCO and MITgcm
2849      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
2850                      updated checkpointing_lev... lists for obcs
2851      - model/src: minor changes in forward_step, plot_field
2852                   added directive for divided adjoint in the_main_loop
2853      - pkg/mdsio: added mdsio_gl_slice
2854

2871    
2872    checkpoint42
2873      Fixed AD-related problems:
2874    o Store directives up-to-date with re-arranged Adams-Bashforth
2875      (mainly thermodynamics.F)
2876    o New store directives for multi-dim. advection schemes
2877      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
2878      * new common block and key passkey
2879      (mainly gad_advection.F)
2880    o Modified store directives for split of dynamics/thermodynamics
2881      for the case ALLOW_KPP
2882    o Cleaned argument list for timestep_tracer.F
2883    
2884    checkpoint41
2885    o re-formatted/added comments in prologues of key subroutines
2886      to work with protex
2887    
2888    checkpoint40
2889    o moved calc_gs, calc_gt and calc_tr1 back to model/src
2890    o added FLT (floats) package from Arne along with demo. experiment
2891    o re-arranged Adams-Bashforth scheme for tracers to allow easier

2905    o added multi-dimensional advection method for tracers
2906      
2907    checkpoint40pre8
2908    o new package rw/
2909      Added method for dumping intermediate local arrays:
2910      mdsio_writetile - same as mdsio_writefield except works from inside
2911                        bi,bj loop
2912      mdsio_writelocal - same as mdsio_writetile except works for local
2913                         arrays
2914      write_local_r? - higher-level wrapper for mdsio_writelocal
2915      Controlled by diagFreq. Defaults to zero (ie. no dumps)
2916      Example given at end of mom_vecinv.F that dumps some local arrays.
2917    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
2918      control flux-form versus vector invariant code.
2919      Switch is runtime flag vectorInvariantMomentum (defaults to false)
2920      or genmake -DISABLE ...
2921    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
2922      (additional storing is now needed for case vecinv;
2923      currently nothing implemented to switch this storing off
2924      in case fluxform is used since no CPP flag available).
2925    
2926    checkpoint40pre7
2927    o bug fix in dynamics.F
2928      calc_viscosity called before k=1,Nr loop.

2935    o corresponding split of calc_diffusivity into
2936      calc_diffusivity, calc_viscosity
2937      (kpp_calc_diff, kpp_calc_visc).
2938    o Added diffkr, kapgm to control variables
2939    o bug fix in gmredi_slope_limit for ldd97
2940    
2941    checkpoint40pre5
2942    o proper initialization of Adams-Bashforth time stepping
2943      + uses forward step for very first step of model (iter=0)
2944    o re-generated *all* output since almost all output is modified by this
2945      change (sorry but we've been putting this one off for about 2 years)
2946      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
2947        *not* regenerated since they are already out of date and I don't
2948        want to create the impression that they are suddenly working.
2949    o removed KAP stuff for DEC's
2950    o modified/added many .cvsignore files in */code and */input
2951    o added new expt "solid-body.cs-32x32x1"
2952      + this uses an alternative form of ini_curvilinear_grid.F which
2953        is not necessarily any better than the current one...
2954    
2955    checkpoint40pre4
2956    o added re-initialisations of utrans,vtrans,rtrans in
2957      calc_common_factors which are crucial for TAF.

2966    o some recomputations of nIter0 for TAMC
2967    
2968  checkpoint40pre2  checkpoint40pre2
2969  o Updated to latest branch of AJA, JMC  o Updated to latest branch of AJA, JMC
