3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint55g_post
7    o Renaming carbon AD experiments to comply with testreport conventions
8    o Updating adjoint of Held-Suarez hs94.1x64x5
9    o Fixing directives for non-ECCO forward_step, after ECCO directives
10      have been fixed to avoid recomp. of do_oceanic_phys
11      Works well for global_ocean.90x40x15,
12      but recomp. issue remains for carbon
13    o Updating adjoint output for natl_box_adjoint after
14      pkg/ecco has been modified (see taga c55d_post)
15    
16    checkpoint55f_post
17    o rename to timeave_init_fixed
18    
19    checkpoint55e_post
20    o some delicate re-shuffle of store directives to avoid one
21      extra call of do_oceanic_physics
22      affects ecco_the_main_loop.F, do_oceanic_physics.F
23      checkpoint_lev1_directives.h
24    o NB: this may break global_ocean adjoint temporarily,
25      but it is clear how to fix it. Will do later, need this now.
26    
27    checkpoint55d_post
28    o ECCO specific cost function terms (up-to-date with 1x1 runs)
29    o ecco_cost_weights is modified to 1x1 runs
30    o modifs to allow observations to be read in as
31      single file or yearly files
32    o enable to read exf forcing fields as either
33      single file or yearly files (flag useExfYearlyFields)
34    checkpoint55d_pre
35    
36    o switch between 2-level and 3-level checkpointing
37    o add ability of MNC to write local and "partial" (eg. 2D slices where
38      the full 3D field is never actually stored) arrays to NetCDF files
39      with the correct (that is, the complete multi-dimensional) set of
40      array indicies
41      - used in mom_vecinv() to write the diagFreq output
42      - tested (demonstrated) in verification/aim.5l_cs
43    o further mnc-ification
44      - add verification/lab_sea to the list with mnc setups
45      - fix undefined mnc v-names in cd_code
46      - add kpp to mnc output (both snapshot and timeave)
47    o non-hydrostatic code
48      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
49        in calc_gw.F
50      - defaults to viscAh
51      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
52        friction or Leith) in non-hydrostatic mode, as long as there is
53        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
54    o pkg/cost
55      extend simple cost functions to treat time mean quantities
56      (T,U,V) via cost_accumulate_state from cost_tile
57    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
58        be 2 times larger than the minimum size the advection scheme requires.
59        now get a perfect conservation of salt in advect_cs test-exp (updated)
60    o GGL90 (Gaspar's TKE mixed layer)
61      - add horizontal diffusion of TKE, requires exchanges in
62        do_fields_blocking_exchanges, horizontal diffusivity is zero by
63        default. In OPA there is no horizontal diffusion of TKE but the
64        mixing coefficients are computed from a horizontal average of TKE of
65        6 points or so. I think that diffusion has a little more physical
66        justification.
67      - clean up ggl90_calc in the hope of reducing memory usage (this hope
68        was in vain)
69      - mask tke-variable in ggl90_init
70    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
71    o fix biharmonic diffusion on CS-grid.
72    o more obcs stuff
73      - added obcs_external_fields_load as an alternative to the EXF-pkg option
74        for reading boundary values. This routine is called from
75        obcs_prescribe_read
76      - updated obcs_check
77      - changed sponge layer relaxation parameter units for days to seconds
78      - turned off sponge layer by default
79      - changed argument list of OBCS_CALC to myTime+deltaTclock
80      - fixed about 35 bugs in obcs_external_fields_load
81    
82    checkpoint55c_post
83    o obcs stuff
84      - new runtime flags useOBCSprescribe, useOBCSbalance
85      - re-arranged obcs_calc
86      - moved exf_getobcs to obcs_prescibe_read
87        obcs_prescibe_read is called after ORLANSKI stuff
88        and independent of it (executable can contain all).
89      - updated obcs_check
90      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
91        These may be necessary only if tangential velocities are
92        prescribed at OB, not sure, needs testing.
93    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
94      which simplifies the calls and passes the ifc check-bounds test
95    
96    checkpoint55b_post
97    o add a 2D scalar, Z location, exchange_2 routine.
98    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
99      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
100      affects advect_cs results (for the wrong reason): update output.txt
101    o use a more standard discretization for biharmonic viscosity ;
102     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
103      affects results of dome set-up: update output.txt
104    o fix gad_advection.F (CubedSphere part), back to version 1.23
105    o fix bug in mom_vi_del2uv.F (CubedSphere part).
106    
107    checkpoint55a_post
108    o merged code to
109      * prescribe/read time-dependent open boundaries
110        (works in conjunction with exf, cal)
111      * sponge layer code for open boundaries
112      * each boundary N/S/E/W now has its own CPP option
113        (healthy for the adjoint)
114    
115    checkpoint55
116    o up-to-date adjoint of previous breaks
117      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
118      - global_ocean_ebm: adjoint still needs fix (TLM ok)
119      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
120      - carbon: * remove tr1-related adjoint verification
121                * add ptracer as control variable
122    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
123      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
124    
125    checkpoint54f_post
126    o in verification/carbin/ remove experiment related to
127      ALLOW_PASSIVE_TRACER (array tr1 etc)
128      code_ad/ input_ad/ results_ad
129    
130    o add two new packages
131      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
132        + subject to optimization (memory)
133      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
134        + subject to reordering (many GOTOs in the original code)
135        + so far opps is called for every (i,j) point, and then operates in
136          the vertical; one may want to reorder the scheme in order operate in
137          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
138          fields)
139    o overhaul of IO so that we now have flags for MDSIO and/or MNC
140      - all verification tests compile and run with linux_ia32_g77
141      - defaults are compatible with current input files--nothing
142        should change if you were not previously using MNC
143      - MNC output has been added in numerous places (eg. timeave)
144        but there are still a few writes not yet do-able with MNC
145        (this is in progress)
146      - flags now allow for either/or/both use of MDSIO and MNC and
147        documentation will soon follow
148      - numerous small formatting cleanups for ProTeX
149    o add version info (via BUILD_INFO.h) to MNC and stdout
150    
151    checkpoint54e_post
152    o add two new packages
153      - pp81 (Packanowski and Philander, 1981), Richardson number and
154        stratification dependent mixing
155      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
156      - these scheme operate in a similar manner as KPP (without ghat, of
157        course), however there is only one diffusivity that is used for both
158        temperature and salinity (and passive tracers)ç
159    o add offline package
160    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
161      provided by Stephanie Dutkiewicz
162    o genmake2: add ability to search for C compilers and cleanup test output
163      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
164    
165    checkpoint54d_post
166    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
167    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
168      leading to additional shift by 5 days each year of integration
169       (i.e. leading to considerable offset over the years)
170    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
171    o start with no AB and no initial filtering (staggerTimeStep):
172      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
173    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
174      (external loading & cpl import/export stay in forward_step.F)
175    o update coupling interface to work with new staggerTimeStep
176    o change MDSIO ptracers_pickup.
177    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
178    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
179    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
180    
181    checkpoint54c_post
182    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
183      this affects (truncation error) output.txt of test-exp:
184       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
185    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
186    o change Qnet to always be the net heat flux, (+upward).
187      affects (truncation error) output of natl_box exp.: updated
188    o define the max number of passive tracers in PTRACERS_SIZE.h
189    o start to test mnc routinely in exp0
190    o add sea-ice loading (sIceLoad) as a new forcing field.
191    
192    checkpoint54b_post
193    o add testreport "-j JOBS" option for parallel builds (tested and pretty
194       impressive on Altix and Opteron systems)
195    o diagnostics can now write NetCDF files through the mnc package
196    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
197    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
198    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
199      affects (truncation error) output of lab_sea & natl_box exp.: updated
200    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
201    
202    checkpoint54a_post
203    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
204    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
205    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
206    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
207      + internal_wave (shift in writing cg2d_ini_res)
208    checkpoint54a_pre
209    
210    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
211      - modified verification/lab_sea and natl_box_adjoint accordingly
212    
213    checkpoint54
214    checkpoint53g_post
215    o prepare splitting of thermodynamics: store convect.counter in common block
216    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
217      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
218    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
219    o new parameter "nShapS": allow to treat differently S from T (nShapT)
220    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
221    o restore adjointability
222    
223    checkpoint53f_post
224    o modifications that affect AIM experiment results (update output.txt):
225      - no advection of S at top interface Nr (pkg/generic_advdiff)
226      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
227    o AIM pkg:
228      - include stability function into surf.Flux derivative relative to Tsurf
229      - calculate clear-sky radiation & surface temp. change (for diagnostics)
230    
231    checkpoint53e_post
232    o merged cylindrical coord configuration
233    o added rotating_tank experiment
234    checkpoint53e_pre
235    
236    checkpoint53d_post
237    o faulks upgraded: re-generate output.txt that have changed:
238       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
239    o Added Bryan and Lewis, 1979, vertical diffusivity profile
240    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
241    o added Sadourny discretization of Coriolis
242      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
243      - re-enabled use of omega3 (useAbsVorticity)
244    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
245      vector-invariant equations
246      - note: does *NOT* yet use same variable visc. for no-slip BC's.
247    o recoded the lateral boundary conditions for non-hydrostatic w, this time
248      hopefully without new bugs
249      - still to do: biharmonic friction for non-hydrostatic w
250    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
251    o regenerated output for global_ocean_ebm (using -ieee)
252    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
253      of mom_common/
254      - simple re-arrangement of instructions within computing loop
255    checkpoint53d_pre
256    
257    checkpoint53c_post
258    o new version of coupler for AIM+thSIce and Ocean models
259     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
260     - land: change Evaporation of snow
261     - aim with thSIce: fix bug in snow-precip.
262    o changes to calc_gw.F
263     - bug fix for w^2 term near the bottom boundary
264     - (hopefully) improve the lateral slip boundary condtions for use with
265        partial/looped cells
266      - because the bug fix changes two verification experiments anyway (exp5
267        and plume on slope), change the lateral boundary condition from half slip
268        to the value of no_slip_sides
269    o ebm package wasnt quite up to the parallel task. Fixed that.
270    o Adjoint of EBM package + verification
271      * TLM OK
272      * ADM not sufficient accuracy yet (needs further testing)
273    
274    checkpoint53b_post
275    o Commiting new energy balance model to repository
276      * package is pkg/ebm
277      * verif. is verification/global_ocean_ebm
278      * references are in ebm_driver.F
279    C      * X. Wang, P. Stone and J. Marotzke, 1999:
280    C        Global thermohaline circulation. Part I:
281    C        Sensitivity to atmospheric moisture transport.
282    C        J. Climate 12(1), 71-82
283    C      * X. Wang, P. Stone and J. Marotzke, 1999:
284    C        Global thermohaline circulation. Part II:
285    C        Sensitivity with interactive transport.
286    C        J. Climate 12(1), 83-91
287    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
288    C        Destabilization of the thermohaline circulation
289    C        by atmospheric eddy transports.
290    C        J. Climate 7(12), 1870-1882
291    o Will need long integration testing.
292    checkpoint53b_pre
293    
294    o created pkg/mom_common in preparation for variable viscosity code
295    o renamed and split ini_mnc_io
296    o pkg/land: only liquid water can diffuse or run-off
297    o AIM using land: soil wetness availability account for snow
298    o added printMapIncludesZeros to EEPARMS namelist
299    
300    checkpoint53a_post
301    o restore TAMC compatiility for exf_constants.h
302      (no usage of _d in .h)
303    o Additional storing in KPP in an attempt to fix
304      TAMC problem with adjoint of KPP code.
305      (no success...)
306      Identical code works fine with TAF.
307    o Fixed verification/natl_box_adjoint experiments.
308      Initial conditions for Experiments 4 and 5 are now
309      set to "SEAICE_initialHEFF=0", which is more reasonable,
310      and hence gives results closer to that of Experiment 2.
311      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
312    
313    checkpoint53
314    o stable checkpoint with up to date adjoint
315      TLM tests only run for 1st grdchk at the moment. Its unclear if
316      this is a code problem or a problem with resetting code for g_
317      variables that is being autogenerated wrong.
318      Otherwise:
319       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
320       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
321         are both still in chaos following their security messes.
322    
323    checkpoint52n_post
324    o various build (mostly genmake2) changes including:
325      - ability to build/run more easily within Cygwin and MacOS X
326      - more complicated Makefiles with a stronger dependence on Gnu Make
327    o pkg/seaice modifications
328      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
329        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
330        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
331      - changed proxy for geostrophic velocity and updated
332        verification/lab_sea/results/* accordingly
333      - removed ADI dynamic solver from pkg/seaice
334      - replaced all occurrences of 1/CSTICE or 1/CSUICE
335        they caused a segmentation fault under certain circumstances
336      - removed unused field WATR
337    o bug fix in exf-package:
338      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
339         now reflect that.
340    o small fixes in the cal-package:
341      - set reference date to first of January for the 'model'-calendar
342      - failing of cal_CheckDate in cal_FullDate now actually results in a
343        warning
344    o small modifications in exf-package to increase flexibility:
345      - change climtempfreeze from a constant to a runtime parameter that
346        is specified in data.exf_clim (default = -1.9)
347      - introduce runtime parameter windstressmax (default = 2.0) that is
348        specified in data.exf
349    o fix in pkg/thsice:
350      - update Evap (Tsf changes) to be consistent with Latent heat flux
351      - maintain snow precipitation unchanged (even if Tsf >=0).
352     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
353    
354    checkpoint52m_post
355    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
356      this does not change any of the results, because myIter=0 in swfrac always
357      lead to jwtype=2 (the default anyway), but the call makes little sense
358      as a default
359    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
360    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
361      atmospheric model (AIM) to use it ; add a "slab ocean" component.
362    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
363    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
364    o extending useSingleCpuIO option to work with new exch2 I/O format
365      - old-style, missing-tile I/O is still accessible by defining CPP
366        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
367    o monitor package can write to NetCDF files and/or STDOUT
368    o fix re-definition bug in MNC_GRID_INIT_ALL()
369    o doc/api_reference added
370      - a framework for building an API Reference Manual using all
371        the "protex" comments embedded in the code
372      - see pkg/generic_advdiff, pkg/mnc for examples
373    o MNC:
374      - make myThid the last argument for all subroutines
375      - new default for the grid files: NO halos
376      - add useMNC and other run-time flags
377      - separate per-file-group handling of the unlimited dimension
378      - early initialization of MNC w/ flags read at the eeboot stage
379        and lookup tables set in initialize_fixed
380      - write all MNC output to a freshly-created directory
381    o thermodynamics sea-ice (thsice) is now tested with testreport.
382    o test exp. advect_cs: use the standard cs32 grid ; update output.
383    o Added functionality to grdchk:
384      pick global i,j,k position (or nearest wet) where to perform check.
385    
386    checkpoint52l_post
387    o new land formulation:
388      a) use ground enthalpy as prognostic variable to ensure exact
389         energy conservation.
390      b) account for water temperature and for latent heat of freezing
391         in all processes (rain, run-off, ground storage)
392      c) compute surface and ground temperature implicitly.
393    o aim_v23 modification for new land model:
394      a) Treat separately land / ocean / sea-ice surface fluxes
395         to allow implicit computation of land & sea-ice surface temp.

413    o fixed bug introduced in pkg/monitor
414    o accuracy ctrlprec = 32 insuffient for gradient checks using
415      averaged fields (I/O via cost_averages)
416      -> use ctrl.h in active_file*.F to control I/O precision.
417    o paramter list of CALL ADTHE_MAIN_LOOP
418    o added initial do_the_model_io to ecco
419    o set all ...Freq to zero after cost_final

422    
423    checkpoint52j_post
424    o fix nchklev in tamc.h for global_ocean...
425    o Bringing flow and store directives up-to-date
426    o Really weird thing!
427      call do_the_model_io from the_main_loop with parameters
428      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
429      TAF places a faulty re-call of initialise_varia
430      after cost_final call which should not be there!
431    checkpoint52j_pre
432    
433    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
434      error messages
435    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src

462    o added useSingleCPUIO flag to monitor.F and mon_out.F
463    o added temporary hack for sea-ice dynamics on the cube:
464      metric terms are ignored and it is assumed that
465      there is no sea-ice on cube faces 1, 2, 4, and 5.
466    
467    checkpoint52f_post
468    o added exch2 cube routines to pkg/exch2

472    
473    checkpoint52e_post
474    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
475      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
476    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
477      to work with implicit vertical advection and AB ;
478    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
479    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
480     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
481    checkpoint52e_pre
482    
483    o fix bug in impldiff when Nr=1 or Nr=2.
484    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
485    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
486    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2

493    o re-tiled many expts to allow comparison in multi-processor mode
494      - updated output accordingly
495      - changed hs94.128x64x5 to use intial T from file rather than use the
496        random number generator
497    o add infrastructure in model routines for fizhi and gridalt packages
498    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
499    o changes to permit hi-res, cubed-sphere, configuration
500      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
501      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
502      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
503        of surface winds for the cube
504      (A verification experiment, based on global_ocean.cs32x15, but with
505       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
506       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
507       complete with example surface forcing files and matlab scripts to look
508       at the output and compare it with that of global_ocean.cs32x15.)
509    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
510       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
511       to conform to the common rule.
512    o check-in the first version of the coupler + interfaces for multi-components
513       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
514       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
515       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
516       - ocean and atmos. share the same horizontal grid (no interpolation).
517       - exchanges between component and coupler is done in forward_step
518    o new verification experiment, cpl_aim+ocn:
519       coupled ocean - AIM atmosphere on cs32 grid.
520    
521    checkpoint52d_pre
522    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
523    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
524    
525    checkpoint52c_post
526    o Fixing OPTIONS files for use of exf:
527      - ALLOW_ECCO not needed
528      - ECCO_CPPOPTIONS.h should not be included from
529        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
530        as has been the case in the past
531      - All cal/exf related options are currently set in
532        single header file. Should remain so until we
533        agree on a consistent new policy.
534    o Removed all CPP options for cal package.
535      cal has no more CPP options.
536    o modified STOREs in GAD_ADVECTION
537    o corrected key comp. for passkey
538    
539    checkpoint52b_post
540    o new version: "thsice" of thermodynamic sea-ice pkg:

542     - modify fluxes but do not change theta directly;
543     - light cleaning of bulk_force pkg (still needed with thsice).
544     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
545       + output_thsice.txt to test thsice & bulk_force pkgs.
546    o put back grid & coriolis monitor output.
547    checkpoint52b_pre
548    
549    o call "do_the_model_io" at the beginning (=> dump initial state)
550    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
551    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
552      (need info on NUMBER_OF_PTRACERS)
553    o missing PTRACERS headers in some routines
554    o default tamc.h in pkg/autodiff supposed to crash
555      to ensure proper customization
556    
557    checkpoint52a_post
558    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
559      - moved surfaceTendencyTice from pkg/seaice to main code
560      - subroutine FREEZE_SURFACE now limits only surface temperature
561        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
562        => new output.txt for global_ocean.cs32x15 & global_with_exf
563      - keep the old version of FREEZE for backward compatibility;
564        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

573    o some bug fixes for #undef REAL4_IS_SLOW
574    
575    checkpoint52 = ecco_c52_e35
576    o after testing adjoints of checkpoint51u_post
577    
578    checkpoint51u_post
579    o this is the post-merge tag of the ecco-branch
580      (needs another clean checkout and re-testing)
581    o various natl_box_adjoint configs and results
582      but no input fields
583    o obcs adjoint not yet merged!
584    o adding ECCO global 1x1 and 2x2 degree configs
585    o updated/extended some store directives for seaice
586    o pkg/ecco now containes ecco-specific part of cost function
587    o top level routines the_main_loop, forward_step
588      supersede those in model/src/
589      previous input data.cost now in data.ecco
590      (new namelist ecco_cost_nml)
591    o in ctrl/ cleaned some cross-dependencies and updated CPP options
592    
593    checkpoint51t_post
594    o this is the pre-merge tag of the ecco-branch
595    
596    checkpoint51s_post
597    o cleanup: removed various obsolete #define-s
598    o pkg/grdchk
599      - renamed 'ph-grd 3' to 'grad-res'
600      - merged from ecco-branch
601        (remaining bug fixes for obcs gradient checks)
602      - additional high-precision output for testreport
603        (grep for 'precision_grdchk_result')
604    
605    checkpoint51r_post
606    o cleaned up or removed CPP_OPTIONS.h files
607    o updated results for some of the tests to reflect the new
608      optfiles (-ieee: -O0 instead of -O3)
609    
610    checkpoint51q_post
611    o cd_code:
612      - moved cd_scheme.F -> cd_code_scheme.F
613      - separate read_checkpoint from cd_code_ini_vars.F
614      - separated cd_code part from write_checkpoint
615      - updated AD_SOURCE, generated .flow

623      - confined inclusion of AD_CONFIG.h to where necessary.
624    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
625    
626    checkpoint51p_post
627    o create initial cd_code package
628      - WARNING: the initialization of fields within packages
629        is broken because INI_FIELDS (where READ_CHECKPOINT is
630        called) is called *before* PACKAGES_INIT_VARIABLES.
631        This seems to be backwards since
632        1) its important to initially zero the entire field including
633           the "halo" region
634        2) zeroing needs to be done *before* reading pickup info
635           and the pickup call might or might not happen in any
636           particular run
637      - this needs an overhaul for R2
638    o cleanup verification/*/code/GMREDI_OPTIONS.h
639    o cleanup testreport
640    
641    checkpoint51o_post
642    o bringing AD-related verif's up to date with genmake2

676         global_ocean.cs32x15, and global_with_exf)
677    o added surface flux output variables to TIMEAVE_STATVARS
678    
679    checkpoint51n_pre
680    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

705    
706    checkpoint51k_post
707    o change default to: useNHMTerms=.FALSE.
