12    o update AIM Cubed-Sphere exp (aim.5l_cs):
13      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
14    o update AIM Equatorial Channel exp:
15      use standard aim_v23 pkg and change the SST fields to be more realistic.
16    o globalFile now works with exch2
17    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
18      mon_vort3.F to make exch2 friendly with >1 tile per cube face

20    
21    checkpoint52i_post
22    o removed CPP_EEOPTIONS.h from verification/*/code
23    o updated the tiling for global_ocean_pressure
24    checkpoint52i_pre
25    
26    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
27      the old pkg/aim).
28    
29    checkpoint52h_pre
30    o shortened offending lines in exch2_send_rx?.template
31    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator

34      old grid files, moved CPP_EEMACROS.h to pkg/exch2
35    o added useSingleCPUIO flag to monitor.F and mon_out.F
36    o added temporary hack for sea-ice dynamics on the cube:
37      metric terms are ignored and it is assumed that
38      there is no sea-ice on cube faces 1, 2, 4, and 5.
39    
40    checkpoint52f_post
41    o added exch2 cube routines to pkg/exch2
42    o modified hs94.cs-32x32x5 to use it

44    checkpoint52f_pre
45    
46    checkpoint52e_post
47    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
48      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
49    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
50      to work with implicit vertical advection and AB ;
51    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.

66    o re-tiled many expts to allow comparison in multi-processor mode
67      - updated output accordingly
68      - changed hs94.128x64x5 to use intial T from file rather than use the
69        random number generator
70    o add infrastructure in model routines for fizhi and gridalt packages
71    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
72    o changes to permit hi-res, cubed-sphere, configuration
73      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
74      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
75      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
76        of surface winds for the cube
77      (A verification experiment, based on global_ocean.cs32x15, but with
78       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
79       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
80       complete with example surface forcing files and matlab scripts to look
81       at the output and compare it with that of global_ocean.cs32x15.)
82    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
83       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
84       to conform to the common rule.
85    o check-in the first version of the coupler + interfaces for multi-components
86       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
87       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
88       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
89       - ocean and atmos. share the same horizontal grid (no interpolation).
90       - exchanges between component and coupler is done in forward_step
91    o new verification experiment, cpl_aim+ocn:
92       coupled ocean - AIM atmosphere on cs32 grid.
93    
94    checkpoint52d_pre
95    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
96    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
97    
98    checkpoint52c_post
99    o Fixing OPTIONS files for use of exf:
100      - ALLOW_ECCO not needed
101      - ECCO_CPPOPTIONS.h should not be included from
102        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
103        as has been the case in the past
104      - All cal/exf related options are currently set in
105        single header file. Should remain so until we
106        agree on a consistent new policy.
107    o Removed all CPP options for cal package.
108      cal has no more CPP options.
109    o modified STOREs in GAD_ADVECTION
110    o corrected key comp. for passkey
111    
112    checkpoint52b_post
113    o new version: "thsice" of thermodynamic sea-ice pkg:
114     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
115     - modify fluxes but do not change theta directly;
116     - light cleaning of bulk_force pkg (still needed with thsice).
117     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
118       + output_thsice.txt to test thsice & bulk_force pkgs.
119    o put back grid & coriolis monitor output.
120    checkpoint52b_pre
121    
122    o call "do_the_model_io" at the beginning (=> dump initial state)
123    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
124    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
125      (need info on NUMBER_OF_PTRACERS)
126    o missing PTRACERS headers in some routines
127    o default tamc.h in pkg/autodiff supposed to crash
128      to ensure proper customization
129    
130    checkpoint52a_post
131    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
132      - moved surfaceTendencyTice from pkg/seaice to main code
133      - subroutine FREEZE_SURFACE now limits only surface temperature
134        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
135        => new output.txt for global_ocean.cs32x15 & global_with_exf
136      - keep the old version of FREEZE for backward compatibility;
137        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

146    o some bug fixes for #undef REAL4_IS_SLOW
147    
148    checkpoint52 = ecco_c52_e35
149    o after testing adjoints of checkpoint51u_post
150    
151    checkpoint51u_post
152    o this is the post-merge tag of the ecco-branch
153      (needs another clean checkout and re-testing)
154    o various natl_box_adjoint configs and results
155      but no input fields
156    o obcs adjoint not yet merged!
157    o adding ECCO global 1x1 and 2x2 degree configs
158    o updated/extended some store directives for seaice
159    o pkg/ecco now containes ecco-specific part of cost function
160    o top level routines the_main_loop, forward_step
161      supersede those in model/src/
162      previous input data.cost now in data.ecco
163      (new namelist ecco_cost_nml)
164    o in ctrl/ cleaned some cross-dependencies and updated CPP options
165    
166    checkpoint51t_post
167    o this is the pre-merge tag of the ecco-branch
168    
169    checkpoint51s_post
170    o cleanup: removed various obsolete #define-s
171    o pkg/grdchk
172      - renamed 'ph-grd 3' to 'grad-res'
173      - merged from ecco-branch
174        (remaining bug fixes for obcs gradient checks)
175      - additional high-precision output for testreport
176        (grep for 'precision_grdchk_result')
177    
178    checkpoint51r_post
179    o cleaned up or removed CPP_OPTIONS.h files
180    o updated results for some of the tests to reflect the new
181      optfiles (-ieee: -O0 instead of -O3)
182    
183    checkpoint51q_post
184    o cd_code:
185      - moved cd_scheme.F -> cd_code_scheme.F
186      - separate read_checkpoint from cd_code_ini_vars.F
187      - separated cd_code part from write_checkpoint
188      - updated AD_SOURCE, generated .flow

190      - Moving cd_code specific store dir.s to pkg/cd_code
191    o ctrl package totally restructured
192      - pack/unpack now optional and decoupled from
193        xx_/adxx_ I/O

197    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
198    
199    checkpoint51p_post
200    o create initial cd_code package
201      - WARNING: the initialization of fields within packages
202        is broken because INI_FIELDS (where READ_CHECKPOINT is
203        called) is called *before* PACKAGES_INIT_VARIABLES.
204        This seems to be backwards since
205        1) its important to initially zero the entire field including
206           the "halo" region
207        2) zeroing needs to be done *before* reading pickup info
208           and the pickup call might or might not happen in any
209           particular run
210      - this needs an overhaul for R2
211    o cleanup verification/*/code/GMREDI_OPTIONS.h
212    o cleanup testreport

224      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
225        change rho -> rho-rhoConst
226      - replace call find_rho to find_rhonum

249         global_ocean.cs32x15, and global_with_exf)
250    o added surface flux output variables to TIMEAVE_STATVARS

420    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
421    o AIM: use true log-P extrapolation for near surface temp (= as in
422        F.Molteni paper) ; update aim.5l_cs output.
423    o New variable in PARM03 for more flexible pickups
424    o somewhat cleaned package initialisation sequence for
425      ctrl/ cost/ ecco/ in packages_... routines
426    
427    checkpoint50g_post
428    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
429      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
430      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
431        made the default because of faster convergence than ADI
432    
433    checkpoint50f_post
434    o exf totally restructured
435      - replaced all exf_set_ routines by one generic exf_set_gen.F
436        and made sure it's still differentiable
437      - split exf_getffields.F into new exf_bulkformulae.F
438      - exf_inscal_/exf_outscal_ suffixes consistent with field names
439      - updated adjoint/makefile and relevant verif. accordingly
440    
441    checkpoint50f_pre
442     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
443          + change Evap over land. (update aim.5l_cs output)
444     o added missing .cvsignores and made uniform across expts
445     o changed configuration of tidal_basin_2d expt
446     o added pkg/debug functions for tracing code in fatal crashes
447     o tidied pkg/monitor to use MONITOR_OPTIONS.h
448     o new fn in pkg/monitor to stop model if solution grows too big
449     o removed lots of single quotes from comments
450    
451    checkpoint50e_post
452    o make KPP work with PTRACERS
453     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
454       nearly a copy of kpp_transport_s
455     - there is no analogue to SurfaceTendencyS, so I have to use
456       gPtr(of the surface layer) instead
457    o add a new platform SunFire+mpi (SunFire 15000) to genmake
458    checkpoint50e_pre
459    
460    checkpoint50d_post
461    o change kpp output from multiple-record state files to single-record state
462      files analogous to write_state.F
463    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
464      analogous to the cg2d-related output.
465    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
466      so that writing to internal file fn (with length 512) fails.
467    checkpoint50d_pre
468    
469    checkpoint50c_post
470    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
471    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
472    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
473    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
474    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
475    
476    checkpoint50c_pre
477    Merging from release1_p13:
478    o bug fix for pkg/seaice dynamic solver
479    o Added SEAICE_initialHEFF to pkg/seaice
480    
481    checkpoint50b_post
482    o store u*,v* in gU,V instead of in guNm1,gvNm1
483    o in order to put the momForcing out of the Adams-Bashforth:
484      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
485      to timestep.F
486    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
487    o re-generate output for highly sensitive test-exp:
488       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
489    
490    checkpoint50b_pre
491    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
492  o corrected CPP option mismatch in exf_Bulk... functions for case  o corrected CPP option mismatch in exf_Bulk... functions for case
493    #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP    #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
