3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint50h_post
7    o new package "land": provide surface BC for AIM.
8    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
9    o AIM: use true log-P extrapolation for near surface temp (= as in
10        F.Molteni paper) ; update aim.5l_cs output.
11    o New variable in PARM03 for more flexible pickups
12    o somewhat cleaned package initialisation sequence for
13      ctrl/ cost/ ecco/ in packages_... routines
14    
15    checkpoint50g_post
16    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
17      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
18      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
19        made the default because of faster convergence than ADI
20    
21    checkpoint50f_post
22    o exf totally restructured
23      - replaced all exf_set_ routines by one generic exf_set_gen.F
24        and made sure it's still differentiable
25      - split exf_getffields.F into new exf_bulkformulae.F
26      - exf_inscal_/exf_outscal_ suffixes consistent with field names
27      - updated adjoint/makefile and relevant verif. accordingly
28    
29    checkpoint50f_pre
30     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
31          + change Evap over land. (update aim.5l_cs output)
32     o added missing .cvsignores and made uniform across expts
33     o changed configuration of tidal_basin_2d expt
34     o added pkg/debug functions for tracing code in fatal crashes
35     o tidied pkg/monitor to use MONITOR_OPTIONS.h
36     o new fn in pkg/monitor to stop model if solution grows too big
37     o removed lots of single quotes from comments
38    
39    checkpoint50e_post
40    o make KPP work with PTRACERS
41     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
42       nearly a copy of kpp_transport_s
43     - there is no analogue to SurfaceTendencyS, so I have to use
44       gPtr(of the surface layer) instead
45    o add a new platform SunFire+mpi (SunFire 15000) to genmake
46    checkpoint50e_pre
47    
48    checkpoint50d_post
49    o change kpp output from multiple-record state files to single-record state
50      files analogous to write_state.F
51    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
52      analogous to the cg2d-related output.
53    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
54      so that writing to internal file fn (with length 512) fails.
55    checkpoint50d_pre
56    
57    checkpoint50c_post
58    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
59    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
60    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
61    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
62    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
63    
64    checkpoint50c_pre
65    Merging from release1_p13:
66    o bug fix for pkg/seaice dynamic solver
67    o Added SEAICE_initialHEFF to pkg/seaice
68    
69    checkpoint50b_post
70    o store u*,v* in gU,V instead of in guNm1,gvNm1
71    o in order to put the momForcing out of the Adams-Bashforth:
72      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
73      to timestep.F
74    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
75    o re-generate output for highly sensitive test-exp:
76       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
77    
78    checkpoint50b_pre
79    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
80    o corrected CPP option mismatch in exf_Bulk... functions for case
81      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
82    
83    checkpoint50a_post
84    o Bug fix for merging between c50 and KPP.
85      ikey was passed from thermodynamics to kpp_calc via
86      common block rather than being recomputed in kpp_calc,
87      in contradiction with new key itdkey.
88      New key ikppkey created, and tamc.h headers updated.
89    
90    checkpoint50
91    - 2nd step of merge with ecco-branch:
92      merge changes in ecco-branch back into main trunk
93    - bug fix in find_alpha
94    - more storing in gmredi_calc_tensor.F, kpp_routines.F
95    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
96    - merged some sliced AD support routines
97    
98  checkpoint49  checkpoint49
99    merged from ecco-branch:
100    o exf:
101      - Enable initialisation of forcing fields to constant
102        (runtime) values.
103      - in exf_getffields.F
104        Reduce i-/j-loop to interior domain, discarding overlaps.
105        That also fixes wrong TAF-key computations for key_1, key_2
106        with bulf formulae.
107      - exf_init.F modify #ifdef for exf_init_evap
108      - exf_getffieldrec.F, ctrl_getrec.F
109        The following INT-usages are not safe:
110          fldsecs  = int(fldsecs/fldperiod)*fldperiod
111          fldcount = int(fldsecs/fldperiod) + 1
112        and were modified.
113    o autodiff: checkpoint_lev...
114      - updated storing for bulk formulae (some arrays were missing)
115      - added state for seaice package
116      - synchronized with main branch
117    o DIVA:
118      Modif.s in
119      - the_main_loop.F
120      - the_model_main.F
121      and added cost_final_restore.F cost_final_store.F
122      o With these changes, it is possible to fully separate
123        the first forward run to compute the cost function (mdthe_main_loop)
124        and adjoint runs over individual DIVA intervals (adthe_main_loop)
125        into separate model executions.
126        This enables better tuning of DIVA to given queue sizes.
127      o Loss of cost function value in consecutive DIVA runs is
128        fixed by storing to 'costfinal' file.
129      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
130        beginning/end of adjoint integration is accounted for.
131      The current changes apply to TAF-1.4.26.
132      TAF has one remaining bug, requiring one manual change
133      (see MITgcm manual).
134    o cal: synchronized between MAIN and ecco-branch
135    
136    checkpoint48i_post
137  o Changes to restore differentiability of code w.r.t. previous tag  o Changes to restore differentiability of code w.r.t. previous tag
138    (mostly adding new routines to make list and replacing    (mostly adding new routines to make list and replacing
139    pressure by totPhiHyd).    pressure by totPhiHyd).
