# Line 4  $Header$ Line 4  $Header$
4      ==============================      ==============================
5    
6    
7    o recoded the lateral boundary conditions for non-hydrostatic w, this time
8      hopefully without new bugs
9      - still to do: biharmonic friction for non-hydrostatic w
10    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
11    o regenerated output for global_ocean_ebm (using -ieee)
12    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
13      of mom_common/
14      - simple re-arrangement of instructions within computing loop
15    checkpoint53d_pre
16    
17    checkpoint53c_post
18    o new version of coupler for AIM+thSIce and Ocean models
19     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
20     - land: change Evaporation of snow
21     - aim with thSIce: fix bug in snow-precip.
22    o changes to calc_gw.F
23     - bug fix for w^2 term near the bottom boundary
24     - (hopefully) improve the lateral slip boundary condtions for use with
25        partial/looped cells
26      - because the bug fix changes two verification experiments anyway (exp5
27        and plume on slope), change the lateral boundary condition from half slip
28        to the value of no_slip_sides
29    o ebm package wasnt quite up to the parallel task. Fixed that.
30    o Adjoint of EBM package + verification
31      * TLM OK
32      * ADM not sufficient accuracy yet (needs further testing)
33    
34    checkpoint53b_post
35    o Commiting new energy balance model to repository
36      * package is pkg/ebm
37      * verif. is verification/global_ocean_ebm
38      * references are in ebm_driver.F
39    C      * X. Wang, P. Stone and J. Marotzke, 1999:
40    C        Global thermohaline circulation. Part I:
41    C        Sensitivity to atmospheric moisture transport.
42    C        J. Climate 12(1), 71-82
43    C      * X. Wang, P. Stone and J. Marotzke, 1999:
44    C        Global thermohaline circulation. Part II:
45    C        Sensitivity with interactive transport.
46    C        J. Climate 12(1), 83-91
47    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
48    C        Destabilization of the thermohaline circulation
49    C        by atmospheric eddy transports.
50    C        J. Climate 7(12), 1870-1882
51    o Will need long integration testing.
52    checkpoint53b_pre
53    
54    o created pkg/mom_common in preparation for variable viscosity code
55    o renamed and split ini_mnc_io
56    o pkg/land: only liquid water can diffuse or run-off
57    o AIM using land: soil wetness availability account for snow
58    o added printMapIncludesZeros to EEPARMS namelist
59    
60    checkpoint53a_post
61    o restore TAMC compatiility for exf_constants.h
62      (no usage of _d in .h)
63    o Additional storing in KPP in an attempt to fix
64      TAMC problem with adjoint of KPP code.
65      (no success...)
66      Identical code works fine with TAF.
67    o Fixed verification/natl_box_adjoint experiments.
68      Initial conditions for Experiments 4 and 5 are now
69      set to "SEAICE_initialHEFF=0", which is more reasonable,
70      and hence gives results closer to that of Experiment 2.
71      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
72    
73    checkpoint53
74    o stable checkpoint with up to date adjoint
75      TLM tests only run for 1st grdchk at the moment. Its unclear if
76      this is a code problem or a problem with resetting code for g_
77      variables that is being autogenerated wrong.
78      Otherwise:
79       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
80       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
81         are both still in chaos following their security messes.
82    
83    checkpoint52n_post
84    o various build (mostly genmake2) changes including:
85      - ability to build/run more easily within Cygwin and MacOS X
86      - more complicated Makefiles with a stronger dependence on Gnu Make
87    o pkg/seaice modifications
88      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
89        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
90        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
91      - changed proxy for geostrophic velocity and updated
92        verification/lab_sea/results/* accordingly
93      - removed ADI dynamic solver from pkg/seaice
94      - replaced all occurrences of 1/CSTICE or 1/CSUICE
95        they caused a segmentation fault under certain circumstances
96      - removed unused field WATR
97    o bug fix in exf-package:
98      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
99         now reflect that.
100    o small fixes in the cal-package:
101      - set reference date to first of January for the 'model'-calendar
102      - failing of cal_CheckDate in cal_FullDate now actually results in a
103        warning
104    o small modifications in exf-package to increase flexibility:
105      - change climtempfreeze from a constant to a runtime parameter that
106        is specified in data.exf_clim (default = -1.9)
107      - introduce runtime parameter windstressmax (default = 2.0) that is
108        specified in data.exf
109    o fix in pkg/thsice:
110      - update Evap (Tsf changes) to be consistent with Latent heat flux
111      - maintain snow precipitation unchanged (even if Tsf >=0).
112     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
113    
114    checkpoint52m_post
115    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
116      this does not change any of the results, because myIter=0 in swfrac always
117      lead to jwtype=2 (the default anyway), but the call makes little sense
118      as a default
119    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
120    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
121      atmospheric model (AIM) to use it ; add a "slab ocean" component.
122    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
123    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
124    o extending useSingleCpuIO option to work with new exch2 I/O format
125      - old-style, missing-tile I/O is still accessible by defining CPP
126        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
127    o monitor package can write to NetCDF files and/or STDOUT
128    o fix re-definition bug in MNC_GRID_INIT_ALL()
129    o doc/api_reference added
130      - a framework for building an API Reference Manual using all
131        the "protex" comments embedded in the code
132      - see pkg/generic_advdiff, pkg/mnc for examples
133    o MNC:
134      - make myThid the last argument for all subroutines
135      - new default for the grid files: NO halos
136      - add useMNC and other run-time flags
137      - separate per-file-group handling of the unlimited dimension
138      - early initialization of MNC w/ flags read at the eeboot stage
139        and lookup tables set in initialize_fixed
140      - write all MNC output to a freshly-created directory
141    o thermodynamics sea-ice (thsice) is now tested with testreport.
142    o test exp. advect_cs: use the standard cs32 grid ; update output.
143    o Added functionality to grdchk:
144      pick global i,j,k position (or nearest wet) where to perform check.
145    
146    checkpoint52l_post
147    o new land formulation:
148      a) use ground enthalpy as prognostic variable to ensure exact
149         energy conservation.
150      b) account for water temperature and for latent heat of freezing
151         in all processes (rain, run-off, ground storage)
152      c) compute surface and ground temperature implicitly.
153    o aim_v23 modification for new land model:
154      a) Treat separately land / ocean / sea-ice surface fluxes
155         to allow implicit computation of land & sea-ice surface temp.
156      b) add snow precipitation.
157    checkpoint52l_pre
158    
159    o fix problem (when 1 tile is empty) in min/max monitor.
160    o fix bug in timeAve (u,vZetatave in common block)
161    o no restoring terms under ice for pkg/seaice
162    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
163    o bug fix for pkg/seaice pickups
164    o change MNC call locations and add coordinate attributes
165    o mask vorticity at the corner ; affects global_ocean.cs output
166    o fix ini_curvilinear_grid ; test CS experiments with mpi
167    o aim.5l_cs: modify sea-ice fraction input file ; update output
168    o exf: Adding simple range check routine for exf fields after read
169    
170    checkpoint52k_post
171    o removed top-level directory "diags"
172      - we migrated these functions to pkg/timeave a long time ago
173    o fixed bug introduced in pkg/monitor
174    o accuracy ctrlprec = 32 insuffient for gradient checks using
175      averaged fields (I/O via cost_averages)
176      -> use ctrl.h in active_file*.F to control I/O precision.
177    o paramter list of CALL ADTHE_MAIN_LOOP
178    o added initial do_the_model_io to ecco
179    o set all ...Freq to zero after cost_final
180      taveFreq, dumpFreq, pChkptFreq
181    o MAIN and ECCO differentiability restored
182    
183    checkpoint52j_post
184    o fix nchklev in tamc.h for global_ocean...
185    o Bringing flow and store directives up-to-date
186    o Really weird thing!
187      call do_the_model_io from the_main_loop with parameters
188      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
189      TAF places a faulty re-call of initialise_varia
190      after cost_final call which should not be there!
191    checkpoint52j_pre
192    
193    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
194      error messages
195    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
196    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
197      debug output
198    o modfied mdsio_writefield.F to handle non-global files under exch2
199    o update AIM Cubed-Sphere exp (aim.5l_cs):
200      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
201    o update AIM Equatorial Channel exp:
202      use standard aim_v23 pkg and change the SST fields to be more realistic.
203    o globalFile now works with exch2
204    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
205      mon_vort3.F to make exch2 friendly with >1 tile per cube face
206    o limit timeave output for hi-res integrations
207    
208    checkpoint52i_post
209    o removed CPP_EEOPTIONS.h from verification/*/code
210    o updated the tiling for global_ocean_pressure
211    checkpoint52i_pre
212    
213    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
214      the old pkg/aim).
215    
216    checkpoint52h_pre
217    o shortened offending lines in exch2_send_rx?.template
218    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
219    o genmake2: add build & execute test for NetCDF code
220    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
221      old grid files, moved CPP_EEMACROS.h to pkg/exch2
222    o added useSingleCPUIO flag to monitor.F and mon_out.F
223    o added temporary hack for sea-ice dynamics on the cube:
224      metric terms are ignored and it is assumed that
225      there is no sea-ice on cube faces 1, 2, 4, and 5.
226    
227    checkpoint52f_post
228    o added exch2 cube routines to pkg/exch2
229    o modified hs94.cs-32x32x5 to use it
230    o added new grid files to hs94.cs-32x32x5
231    checkpoint52f_pre
232    
233    checkpoint52e_post
234    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
235      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
236    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
237      to work with implicit vertical advection and AB ;
238    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
239    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
240     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
241    checkpoint52e_pre
242    
243    o fix bug in impldiff when Nr=1 or Nr=2.
244    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
245    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
246    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
247      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
248    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
249    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
250    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
251    
252    checkpoint52d_post
253    o re-tiled many expts to allow comparison in multi-processor mode
254      - updated output accordingly
255      - changed hs94.128x64x5 to use intial T from file rather than use the
256        random number generator
257    o add infrastructure in model routines for fizhi and gridalt packages
258    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
259    o changes to permit hi-res, cubed-sphere, configuration
260      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
261      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
262      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
263        of surface winds for the cube
264      (A verification experiment, based on global_ocean.cs32x15, but with
265       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
266       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
267       complete with example surface forcing files and matlab scripts to look
268       at the output and compare it with that of global_ocean.cs32x15.)
269    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
270       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
271       to conform to the common rule.
272    o check-in the first version of the coupler + interfaces for multi-components
273       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
274       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
275       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
276       - ocean and atmos. share the same horizontal grid (no interpolation).
277       - exchanges between component and coupler is done in forward_step
278    o new verification experiment, cpl_aim+ocn:
279       coupled ocean - AIM atmosphere on cs32 grid.
280    
281    checkpoint52d_pre
282    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
283    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
284    
285    checkpoint52c_post
286    o Fixing OPTIONS files for use of exf:
287      - ALLOW_ECCO not needed
288      - ECCO_CPPOPTIONS.h should not be included from
289        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
290        as has been the case in the past
291      - All cal/exf related options are currently set in
292        single header file. Should remain so until we
293        agree on a consistent new policy.
294    o Removed all CPP options for cal package.
295      cal has no more CPP options.
296    o modified STOREs in GAD_ADVECTION
297    o corrected key comp. for passkey
298    
299    checkpoint52b_post
300    o new version: "thsice" of thermodynamic sea-ice pkg:
301     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
302     - modify fluxes but do not change theta directly;
303     - light cleaning of bulk_force pkg (still needed with thsice).
304     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
305       + output_thsice.txt to test thsice & bulk_force pkgs.
306    o put back grid & coriolis monitor output.
307    checkpoint52b_pre
308    
309    o call "do_the_model_io" at the beginning (=> dump initial state)
310    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
311    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
312      (need info on NUMBER_OF_PTRACERS)
313    o missing PTRACERS headers in some routines
314    o default tamc.h in pkg/autodiff supposed to crash
315      to ensure proper customization
316    
317    checkpoint52a_post
318    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
319      - moved surfaceTendencyTice from pkg/seaice to main code
320      - subroutine FREEZE_SURFACE now limits only surface temperature
321        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
322        => new output.txt for global_ocean.cs32x15 & global_with_exf
323      - keep the old version of FREEZE for backward compatibility;
324        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
325      - corresponding modifs for TAF directives
326    o added surface flux output variables to TIMEAVE_STATVARS
327    o time-averaged output for pkg/ptracers
328    o fix problem with ECCO-related divided adjoint
329      snapshot file was missing some ad-variables,
330      but no warning issued by TAF
331    
332    checkpoint52a_pre
333    o some bug fixes for #undef REAL4_IS_SLOW
334    
335    checkpoint52 = ecco_c52_e35
336    o after testing adjoints of checkpoint51u_post
337    
338    checkpoint51u_post
339    o this is the post-merge tag of the ecco-branch
340      (needs another clean checkout and re-testing)
341    o various natl_box_adjoint configs and results
342      but no input fields
343    o obcs adjoint not yet merged!
344    o adding ECCO global 1x1 and 2x2 degree configs
345    o updated/extended some store directives for seaice
346    o pkg/ecco now containes ecco-specific part of cost function
347    o top level routines the_main_loop, forward_step
348      supersede those in model/src/
349      previous input data.cost now in data.ecco
350      (new namelist ecco_cost_nml)
351    o in ctrl/ cleaned some cross-dependencies and updated CPP options
352    
353    checkpoint51t_post
354    o this is the pre-merge tag of the ecco-branch
355    
356    checkpoint51s_post
357    o cleanup: removed various obsolete #define-s
358    o pkg/grdchk
359      - renamed 'ph-grd 3' to 'grad-res'
360      - merged from ecco-branch
361        (remaining bug fixes for obcs gradient checks)
362      - additional high-precision output for testreport
363        (grep for 'precision_grdchk_result')
364    
365    checkpoint51r_post
366    o cleaned up or removed CPP_OPTIONS.h files
367    o updated results for some of the tests to reflect the new
368      optfiles (-ieee: -O0 instead of -O3)
369    
370    checkpoint51q_post
371    o cd_code:
372      - moved cd_scheme.F -> cd_code_scheme.F
373      - separate read_checkpoint from cd_code_ini_vars.F
374      - separated cd_code part from write_checkpoint
375      - updated AD_SOURCE, generated .flow
376      - added CD_CODE_VARS.h to the_main_loop
377      - Moving cd_code specific store dir.s to pkg/cd_code
378    o ctrl package totally restructured
379      - pack/unpack now optional and decoupled from
380        xx_/adxx_ I/O
381      - ctrl_pack/unpack cleaned
382        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
383      - confined inclusion of AD_CONFIG.h to where necessary.
384    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
385    
386    checkpoint51p_post
387    o create initial cd_code package
388      - WARNING: the initialization of fields within packages
389        is broken because INI_FIELDS (where READ_CHECKPOINT is
390        called) is called *before* PACKAGES_INIT_VARIABLES.
391        This seems to be backwards since
392        1) its important to initially zero the entire field including
393           the "halo" region
394        2) zeroing needs to be done *before* reading pickup info
395           and the pickup call might or might not happen in any
396           particular run
397      - this needs an overhaul for R2
398    o cleanup verification/*/code/GMREDI_OPTIONS.h
399    o cleanup testreport
400    
401    checkpoint51o_post
402    o bringing AD-related verif's up to date with genmake2
403      - carbon/
404      - global_ocean.90x40x15/
405      - hs.94.1x64x5/
406      - (front_relax/ )
