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

486    o some bug fixes for #undef REAL4_IS_SLOW
487    
488    checkpoint52 = ecco_c52_e35
489    o after testing adjoints of checkpoint51u_post
490    
491    checkpoint51u_post
492    o this is the post-merge tag of the ecco-branch
493      (needs another clean checkout and re-testing)
494    o various natl_box_adjoint configs and results
495      but no input fields
496    o obcs adjoint not yet merged!
497    o adding ECCO global 1x1 and 2x2 degree configs
498    o updated/extended some store directives for seaice
499    o pkg/ecco now containes ecco-specific part of cost function
500    o top level routines the_main_loop, forward_step
501      supersede those in model/src/
502      previous input data.cost now in data.ecco
503      (new namelist ecco_cost_nml)
504    o in ctrl/ cleaned some cross-dependencies and updated CPP options
505    
506    checkpoint51t_post
507    o this is the pre-merge tag of the ecco-branch
508    
509    checkpoint51s_post
510    o cleanup: removed various obsolete #define-s
511    o pkg/grdchk
512      - renamed 'ph-grd 3' to 'grad-res'
513      - merged from ecco-branch
514        (remaining bug fixes for obcs gradient checks)
515      - additional high-precision output for testreport
516        (grep for 'precision_grdchk_result')
517    
518    checkpoint51r_post
519    o cleaned up or removed CPP_OPTIONS.h files
520    o updated results for some of the tests to reflect the new
521      optfiles (-ieee: -O0 instead of -O3)
522    
523    checkpoint51q_post
524    o cd_code:
525      - moved cd_scheme.F -> cd_code_scheme.F
526      - separate read_checkpoint from cd_code_ini_vars.F
527      - separated cd_code part from write_checkpoint
528      - updated AD_SOURCE, generated .flow
529      - added CD_CODE_VARS.h to the_main_loop
530      - Moving cd_code specific store dir.s to pkg/cd_code
531    o ctrl package totally restructured
532      - pack/unpack now optional and decoupled from
533        xx_/adxx_ I/O
534      - ctrl_pack/unpack cleaned
535        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
536      - confined inclusion of AD_CONFIG.h to where necessary.
537    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
538    
539    checkpoint51p_post
540    o create initial cd_code package
541      - WARNING: the initialization of fields within packages
542        is broken because INI_FIELDS (where READ_CHECKPOINT is
543        called) is called *before* PACKAGES_INIT_VARIABLES.
544        This seems to be backwards since
545        1) its important to initially zero the entire field including
546           the "halo" region
547        2) zeroing needs to be done *before* reading pickup info
548           and the pickup call might or might not happen in any
549           particular run
550      - this needs an overhaul for R2
551    o cleanup verification/*/code/GMREDI_OPTIONS.h
552    o cleanup testreport
553    
554    checkpoint51o_post

589         global_ocean.cs32x15, and global_with_exf)
590    o added surface flux output variables to TIMEAVE_STATVARS
591    
592    checkpoint51n_pre
593    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

618    
619    checkpoint51k_post
620    o change default to: useNHMTerms=.FALSE.
