3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint55b_post
7    o add a 2D scalar, Z location, exchange_2 routine.
8    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
9      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
10      affects advect_cs results (for the wrong reason): update output.txt
11    o use a more standard discretization for biharmonic viscosity ;
12     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
13      affects results of dome set-up: update output.txt
14    o fix gad_advection.F (CubedSphere part), back to version 1.23
15    o fix bug in mom_vi_del2uv.F (CubedSphere part).
16    
17    checkpoint55a_post
18    o merged code to
19      * prescribe/read time-dependent open boundaries
20        (works in conjunction with exf, cal)
21      * sponge layer code for open boundaries
22      * each boundary N/S/E/W now has its own CPP option
23        (healthy for the adjoint)
24    
25    checkpoint55
26    o up-to-date adjoint of previous breaks
27      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
28      - global_ocean_ebm: adjoint still needs fix (TLM ok)
29      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
30      - carbon: * remove tr1-related adjoint verification
31                * add ptracer as control variable
32    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
33      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
34    
35    checkpoint54f_post
36    o in verification/carbin/ remove experiment related to
37      ALLOW_PASSIVE_TRACER (array tr1 etc)
38      code_ad/ input_ad/ results_ad
39    
40    o add two new packages
41      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
42        + subject to optimization (memory)
43      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
44        + subject to reordering (many GOTOs in the original code)
45        + so far opps is called for every (i,j) point, and then operates in
46          the vertical; one may want to reorder the scheme in order operate in
47          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
48          fields)
49    o overhaul of IO so that we now have flags for MDSIO and/or MNC
50      - all verification tests compile and run with linux_ia32_g77
51      - defaults are compatible with current input files--nothing
52        should change if you were not previously using MNC
53      - MNC output has been added in numerous places (eg. timeave)
54        but there are still a few writes not yet do-able with MNC
55        (this is in progress)
56      - flags now allow for either/or/both use of MDSIO and MNC and
57        documentation will soon follow
58      - numerous small formatting cleanups for ProTeX
59    o add version info (via BUILD_INFO.h) to MNC and stdout
60    
61    checkpoint54e_post
62    o add two new packages
63      - pp81 (Packanowski and Philander, 1981), Richardson number and
64        stratification dependent mixing
65      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
66      - these scheme operate in a similar manner as KPP (without ghat, of
67        course), however there is only one diffusivity that is used for both
68        temperature and salinity (and passive tracers)ç
69    o add offline package
70    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
71      provided by Stephanie Dutkiewicz
72    o genmake2: add ability to search for C compilers and cleanup test output
73      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
74    
75    checkpoint54d_post
76    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
77    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
78      leading to additional shift by 5 days each year of integration
79       (i.e. leading to considerable offset over the years)
80    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
81    o start with no AB and no initial filtering (staggerTimeStep):
82      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
83    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
84      (external loading & cpl import/export stay in forward_step.F)
85    o update coupling interface to work with new staggerTimeStep
86    o change MDSIO ptracers_pickup.
87    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
88    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
89    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
90    
91    checkpoint54c_post
92    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
93      this affects (truncation error) output.txt of test-exp:
94       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
95    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
96    o change Qnet to always be the net heat flux, (+upward).
97      affects (truncation error) output of natl_box exp.: updated
98    o define the max number of passive tracers in PTRACERS_SIZE.h
99    o start to test mnc routinely in exp0
100    o add sea-ice loading (sIceLoad) as a new forcing field.
101    
102    checkpoint54b_post
103    o add testreport "-j JOBS" option for parallel builds (tested and pretty
104       impressive on Altix and Opteron systems)
105    o diagnostics can now write NetCDF files through the mnc package
106    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
107    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
108    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
109      affects (truncation error) output of lab_sea & natl_box exp.: updated
110    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
111    
112    checkpoint54a_post
113    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
114    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
115    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
116    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
117      + internal_wave (shift in writing cg2d_ini_res)
118    checkpoint54a_pre
119    
120    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
121      - modified verification/lab_sea and natl_box_adjoint accordingly
122    
123    checkpoint54
124    checkpoint53g_post
125    o prepare splitting of thermodynamics: store convect.counter in common block
126    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
127      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
128    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
129    o new parameter "nShapS": allow to treat differently S from T (nShapT)
130    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
131    o restore adjointability
132    
133    checkpoint53f_post
134    o modifications that affect AIM experiment results (update output.txt):
135      - no advection of S at top interface Nr (pkg/generic_advdiff)
136      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
137    o AIM pkg:
138      - include stability function into surf.Flux derivative relative to Tsurf
139      - calculate clear-sky radiation & surface temp. change (for diagnostics)
140    
141    checkpoint53e_post
142    o merged cylindrical coord configuration
143    o added rotating_tank experiment
144    checkpoint53e_pre
145    
146    checkpoint53d_post
147    o faulks upgraded: re-generate output.txt that have changed:
148       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
149    o Added Bryan and Lewis, 1979, vertical diffusivity profile
150    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
151    o added Sadourny discretization of Coriolis
152      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
153      - re-enabled use of omega3 (useAbsVorticity)
154    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
155      vector-invariant equations
156      - note: does *NOT* yet use same variable visc. for no-slip BC's.
157    o recoded the lateral boundary conditions for non-hydrostatic w, this time
158      hopefully without new bugs
159      - still to do: biharmonic friction for non-hydrostatic w
160    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
161    o regenerated output for global_ocean_ebm (using -ieee)
162    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
163      of mom_common/
164      - simple re-arrangement of instructions within computing loop
165    checkpoint53d_pre
166    
167    checkpoint53c_post
168    o new version of coupler for AIM+thSIce and Ocean models
169     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
170     - land: change Evaporation of snow
171     - aim with thSIce: fix bug in snow-precip.
172    o changes to calc_gw.F
173     - bug fix for w^2 term near the bottom boundary
174     - (hopefully) improve the lateral slip boundary condtions for use with
175        partial/looped cells
176      - because the bug fix changes two verification experiments anyway (exp5
177        and plume on slope), change the lateral boundary condition from half slip
178        to the value of no_slip_sides
179    o ebm package wasnt quite up to the parallel task. Fixed that.
180    o Adjoint of EBM package + verification
181      * TLM OK
182      * ADM not sufficient accuracy yet (needs further testing)
183    
184    checkpoint53b_post
185    o Commiting new energy balance model to repository
186      * package is pkg/ebm
187      * verif. is verification/global_ocean_ebm
188      * references are in ebm_driver.F
189    C      * X. Wang, P. Stone and J. Marotzke, 1999:
190    C        Global thermohaline circulation. Part I:
191    C        Sensitivity to atmospheric moisture transport.
192    C        J. Climate 12(1), 71-82
193    C      * X. Wang, P. Stone and J. Marotzke, 1999:
194    C        Global thermohaline circulation. Part II:
195    C        Sensitivity with interactive transport.
196    C        J. Climate 12(1), 83-91
197    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
198    C        Destabilization of the thermohaline circulation
199    C        by atmospheric eddy transports.
200    C        J. Climate 7(12), 1870-1882
201    o Will need long integration testing.
202    checkpoint53b_pre
203    
204    o created pkg/mom_common in preparation for variable viscosity code
205    o renamed and split ini_mnc_io
206    o pkg/land: only liquid water can diffuse or run-off
207    o AIM using land: soil wetness availability account for snow
208    o added printMapIncludesZeros to EEPARMS namelist
209    
210    checkpoint53a_post
211    o restore TAMC compatiility for exf_constants.h
212      (no usage of _d in .h)
213    o Additional storing in KPP in an attempt to fix
214      TAMC problem with adjoint of KPP code.
215      (no success...)
216      Identical code works fine with TAF.
217    o Fixed verification/natl_box_adjoint experiments.
218      Initial conditions for Experiments 4 and 5 are now
219      set to "SEAICE_initialHEFF=0", which is more reasonable,
220      and hence gives results closer to that of Experiment 2.
221      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
222    
223    checkpoint53
224    o stable checkpoint with up to date adjoint
225      TLM tests only run for 1st grdchk at the moment. Its unclear if
226      this is a code problem or a problem with resetting code for g_
227      variables that is being autogenerated wrong.
228      Otherwise:
229       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
230       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
231         are both still in chaos following their security messes.
232    
233    checkpoint52n_post
234    o various build (mostly genmake2) changes including:
235      - ability to build/run more easily within Cygwin and MacOS X
236      - more complicated Makefiles with a stronger dependence on Gnu Make
237    o pkg/seaice modifications
238      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
239        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
240        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
241      - changed proxy for geostrophic velocity and updated
242        verification/lab_sea/results/* accordingly
243      - removed ADI dynamic solver from pkg/seaice
244      - replaced all occurrences of 1/CSTICE or 1/CSUICE
245        they caused a segmentation fault under certain circumstances
246      - removed unused field WATR
247    o bug fix in exf-package:
248      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
249         now reflect that.
250    o small fixes in the cal-package:
251      - set reference date to first of January for the 'model'-calendar
252      - failing of cal_CheckDate in cal_FullDate now actually results in a
253        warning
254    o small modifications in exf-package to increase flexibility:
255      - change climtempfreeze from a constant to a runtime parameter that
256        is specified in data.exf_clim (default = -1.9)
257      - introduce runtime parameter windstressmax (default = 2.0) that is
258        specified in data.exf
259    o fix in pkg/thsice:
260      - update Evap (Tsf changes) to be consistent with Latent heat flux
261      - maintain snow precipitation unchanged (even if Tsf >=0).
262     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
263    
264    checkpoint52m_post
265    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
266      this does not change any of the results, because myIter=0 in swfrac always
267      lead to jwtype=2 (the default anyway), but the call makes little sense
268      as a default
269    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
270    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
271      atmospheric model (AIM) to use it ; add a "slab ocean" component.
272    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
273    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
274    o extending useSingleCpuIO option to work with new exch2 I/O format
275      - old-style, missing-tile I/O is still accessible by defining CPP
276        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
277    o monitor package can write to NetCDF files and/or STDOUT
278    o fix re-definition bug in MNC_GRID_INIT_ALL()
279    o doc/api_reference added
280      - a framework for building an API Reference Manual using all
281        the "protex" comments embedded in the code
282      - see pkg/generic_advdiff, pkg/mnc for examples
283    o MNC:
284      - make myThid the last argument for all subroutines
285      - new default for the grid files: NO halos
286      - add useMNC and other run-time flags
287      - separate per-file-group handling of the unlimited dimension
288      - early initialization of MNC w/ flags read at the eeboot stage
289        and lookup tables set in initialize_fixed
290      - write all MNC output to a freshly-created directory
291    o thermodynamics sea-ice (thsice) is now tested with testreport.
292    o test exp. advect_cs: use the standard cs32 grid ; update output.
293    o Added functionality to grdchk:
294      pick global i,j,k position (or nearest wet) where to perform check.
295    
296    checkpoint52l_post
297    o new land formulation:
298      a) use ground enthalpy as prognostic variable to ensure exact
299         energy conservation.
300      b) account for water temperature and for latent heat of freezing
301         in all processes (rain, run-off, ground storage)
302      c) compute surface and ground temperature implicitly.
303    o aim_v23 modification for new land model:
304      a) Treat separately land / ocean / sea-ice surface fluxes
305         to allow implicit computation of land & sea-ice surface temp.
306      b) add snow precipitation.
307    checkpoint52l_pre
308    
309    o fix problem (when 1 tile is empty) in min/max monitor.
310    o fix bug in timeAve (u,vZetatave in common block)
311    o no restoring terms under ice for pkg/seaice
312    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
313    o bug fix for pkg/seaice pickups
314    o change MNC call locations and add coordinate attributes
315    o mask vorticity at the corner ; affects global_ocean.cs output
316    o fix ini_curvilinear_grid ; test CS experiments with mpi
317    o aim.5l_cs: modify sea-ice fraction input file ; update output
318    o exf: Adding simple range check routine for exf fields after read
319    
320    checkpoint52k_post
321    o removed top-level directory "diags"
322      - we migrated these functions to pkg/timeave a long time ago
323    o fixed bug introduced in pkg/monitor
324    o accuracy ctrlprec = 32 insuffient for gradient checks using
325      averaged fields (I/O via cost_averages)
326      -> use ctrl.h in active_file*.F to control I/O precision.
327    o paramter list of CALL ADTHE_MAIN_LOOP
328    o added initial do_the_model_io to ecco
329    o set all ...Freq to zero after cost_final
330      taveFreq, dumpFreq, pChkptFreq
331    o MAIN and ECCO differentiability restored
332    
333    checkpoint52j_post
334    o fix nchklev in tamc.h for global_ocean...
335    o Bringing flow and store directives up-to-date
336    o Really weird thing!
337      call do_the_model_io from the_main_loop with parameters
338      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
339      TAF places a faulty re-call of initialise_varia
340      after cost_final call which should not be there!
341    checkpoint52j_pre
342    
343    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
344      error messages
345    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
346    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
347      debug output
348    o modfied mdsio_writefield.F to handle non-global files under exch2
349    o update AIM Cubed-Sphere exp (aim.5l_cs):
350      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
351    o update AIM Equatorial Channel exp:
352      use standard aim_v23 pkg and change the SST fields to be more realistic.
353    o globalFile now works with exch2
354    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
355      mon_vort3.F to make exch2 friendly with >1 tile per cube face
356    o limit timeave output for hi-res integrations
357    
358    checkpoint52i_post
359    o removed CPP_EEOPTIONS.h from verification/*/code
360    o updated the tiling for global_ocean_pressure
361    checkpoint52i_pre
362    
363    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
364      the old pkg/aim).
365    
366    checkpoint52h_pre
367    o shortened offending lines in exch2_send_rx?.template
368    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
369    o genmake2: add build & execute test for NetCDF code
370    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
371      old grid files, moved CPP_EEMACROS.h to pkg/exch2
372    o added useSingleCPUIO flag to monitor.F and mon_out.F
373    o added temporary hack for sea-ice dynamics on the cube:
374      metric terms are ignored and it is assumed that
375      there is no sea-ice on cube faces 1, 2, 4, and 5.
376    
377    checkpoint52f_post
378    o added exch2 cube routines to pkg/exch2
379    o modified hs94.cs-32x32x5 to use it
380    o added new grid files to hs94.cs-32x32x5
381    checkpoint52f_pre
382    
383    checkpoint52e_post
384    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
385      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
386    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
387      to work with implicit vertical advection and AB ;
388    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
389    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
390     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
391    checkpoint52e_pre
392    
393    o fix bug in impldiff when Nr=1 or Nr=2.
394    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
395    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
396    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
397      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
398    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
399    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
400    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
401    
402    checkpoint52d_post
403    o re-tiled many expts to allow comparison in multi-processor mode
404      - updated output accordingly
405      - changed hs94.128x64x5 to use intial T from file rather than use the
406        random number generator
407    o add infrastructure in model routines for fizhi and gridalt packages
408    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
409    o changes to permit hi-res, cubed-sphere, configuration
410      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
411      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
412      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
413        of surface winds for the cube
414      (A verification experiment, based on global_ocean.cs32x15, but with
415       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
416       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
417       complete with example surface forcing files and matlab scripts to look
418       at the output and compare it with that of global_ocean.cs32x15.)
419    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
420       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
421       to conform to the common rule.
422    o check-in the first version of the coupler + interfaces for multi-components
423       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
424       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
425       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
426       - ocean and atmos. share the same horizontal grid (no interpolation).
427       - exchanges between component and coupler is done in forward_step
428    o new verification experiment, cpl_aim+ocn:
429       coupled ocean - AIM atmosphere on cs32 grid.
430    
431    checkpoint52d_pre
432    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
433    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
434    
435    checkpoint52c_post
436    o Fixing OPTIONS files for use of exf:
437      - ALLOW_ECCO not needed
438      - ECCO_CPPOPTIONS.h should not be included from
439        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
440        as has been the case in the past
441      - All cal/exf related options are currently set in
442        single header file. Should remain so until we
443        agree on a consistent new policy.
444    o Removed all CPP options for cal package.
445      cal has no more CPP options.
446    o modified STOREs in GAD_ADVECTION
447    o corrected key comp. for passkey
448    
449    checkpoint52b_post
450    o new version: "thsice" of thermodynamic sea-ice pkg:
451     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
452     - modify fluxes but do not change theta directly;
453     - light cleaning of bulk_force pkg (still needed with thsice).
454     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
455       + output_thsice.txt to test thsice & bulk_force pkgs.
456    o put back grid & coriolis monitor output.
457    checkpoint52b_pre
458    
459    o call "do_the_model_io" at the beginning (=> dump initial state)
460    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
461    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
462      (need info on NUMBER_OF_PTRACERS)
463    o missing PTRACERS headers in some routines
464    o default tamc.h in pkg/autodiff supposed to crash
465      to ensure proper customization
466    
467    checkpoint52a_post
468    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
469      - moved surfaceTendencyTice from pkg/seaice to main code
470      - subroutine FREEZE_SURFACE now limits only surface temperature
471        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
472        => new output.txt for global_ocean.cs32x15 & global_with_exf
473      - keep the old version of FREEZE for backward compatibility;
474        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
475      - corresponding modifs for TAF directives
476    o added surface flux output variables to TIMEAVE_STATVARS
477    o time-averaged output for pkg/ptracers
478    o fix problem with ECCO-related divided adjoint
479      snapshot file was missing some ad-variables,
480      but no warning issued by TAF
481    
482    checkpoint52a_pre
483    o some bug fixes for #undef REAL4_IS_SLOW
484    
485    checkpoint52 = ecco_c52_e35
486    o after testing adjoints of checkpoint51u_post
487    
488    checkpoint51u_post
489    o this is the post-merge tag of the ecco-branch
490      (needs another clean checkout and re-testing)
491    o various natl_box_adjoint configs and results
492      but no input fields
493    o obcs adjoint not yet merged!
494    o adding ECCO global 1x1 and 2x2 degree configs
495    o updated/extended some store directives for seaice
496    o pkg/ecco now containes ecco-specific part of cost function
497    o top level routines the_main_loop, forward_step
498      supersede those in model/src/
499      previous input data.cost now in data.ecco
500      (new namelist ecco_cost_nml)
501    o in ctrl/ cleaned some cross-dependencies and updated CPP options
502    
503    checkpoint51t_post
504    o this is the pre-merge tag of the ecco-branch
505    
506    checkpoint51s_post
507    o cleanup: removed various obsolete #define-s
508    o pkg/grdchk
509      - renamed 'ph-grd 3' to 'grad-res'
510      - merged from ecco-branch
511        (remaining bug fixes for obcs gradient checks)
512      - additional high-precision output for testreport
513        (grep for 'precision_grdchk_result')
514    
515    checkpoint51r_post
516    o cleaned up or removed CPP_OPTIONS.h files
517    o updated results for some of the tests to reflect the new
518      optfiles (-ieee: -O0 instead of -O3)
519    
520    checkpoint51q_post
521    o cd_code:
522      - moved cd_scheme.F -> cd_code_scheme.F
523      - separate read_checkpoint from cd_code_ini_vars.F
524      - separated cd_code part from write_checkpoint
525      - updated AD_SOURCE, generated .flow
526      - added CD_CODE_VARS.h to the_main_loop
527      - Moving cd_code specific store dir.s to pkg/cd_code
528    o ctrl package totally restructured
529      - pack/unpack now optional and decoupled from
530        xx_/adxx_ I/O
531      - ctrl_pack/unpack cleaned
532        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
533      - confined inclusion of AD_CONFIG.h to where necessary.
534    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
535    
536    checkpoint51p_post
537    o create initial cd_code package
538      - WARNING: the initialization of fields within packages
539        is broken because INI_FIELDS (where READ_CHECKPOINT is
540        called) is called *before* PACKAGES_INIT_VARIABLES.
541        This seems to be backwards since
542        1) its important to initially zero the entire field including
543           the "halo" region
544        2) zeroing needs to be done *before* reading pickup info
545           and the pickup call might or might not happen in any
546           particular run
547      - this needs an overhaul for R2
548    o cleanup verification/*/code/GMREDI_OPTIONS.h
549    o cleanup testreport
550    
551    checkpoint51o_post
552    o bringing AD-related verif's up to date with genmake2
553      - carbon/
554      - global_ocean.90x40x15/
555      - hs.94.1x64x5/
556      - (front_relax/ )
557    o (more) consistent directory structure for AD-related verif.'s
558    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
559    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
560    o bug fix in find_alpha.F for MDJWF:
561      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
562        change rho -> rho-rhoConst
563      - replace call find_rho to find_rhonum
564    o initialisation of rFlx extended to full array (required by TAF)
565      and shifted to thermodynamics
566    o removed PTRACERS.h in ptracers routine
567    o added surfacetendencyPtr to S/R parameter list pracers_forcing
568    o Correcting initialisations for fVerU, fVerV.
569    o helping TAF to recognize dependency on kUp for
570      fVerU, fVerV
571    o Replacing delZ by delR in pkg/ctrl/
572    checkpoint51o_pre
573    
574    o undid all of cp51 pending some cleanups and discussion
575    o added the [#include "AD_CONFIG.h"] statement to all files that need
576       it for adjoint/tl #defines
577     o re-worked the build logic in genmake2 to support AD_CONFIG.h
578     o removed tools/genmake since it no longer works
579    
580  checkpoint51n_post  checkpoint51n_post
581  o modifications to make FREEZE flux visible to pkg/kpp  o modifications to make FREEZE flux visible to pkg/kpp
