4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o gmredi(fm07):
8      - add lower limit on Transition layer thickness D + lower limit on D/lambda
9      - allow to set few more params from data.gmredi
10    o pkg ggl90:
11          - add missing sqrt(2) factor in computation of mixing length
12            scale in ggl90_calc.F
13            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
14    
15    checkpoint61d
16    o adjoint modifs
17      - adapt to new field rhoInSitu
18      - allow to revert from StoreDynVars2D, StoreDynVars3D
19        to individual fields
20        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
21    o store 3-D (in-situ) density in commom block (DYNVARS.h)
22     - save 1 rho computation.
23     - no longer modify T & S inland when using down_slope pkg.
24    o gad_som : allow to switch to SOM advection for T & S without corresponding
25      pickup files (using new S/R: MDS_CHECK4FILE).
26    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
27      (for useSingleCpuIO to work in multi-threaded)
28    o pkg/shelfice:
29     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
30       with SHELFICEtopoFile in data.shelfice
31     - move code for reading ice shelf topography and modifying hFacC into separate
32       subroutines of the shelfice package
33     - separate initialisation of "fixed" and "variable" variables
34     - kTopC is not (yet) replaced by kSurfC, although this is possible
35    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
36    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
37      and rename:
38      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
39      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
40    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
41    
42    checkpoint61c
43    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
44      to add mass source/sink of fluid in the interior (3-D generalisation
45      of oceanic real-fresh water flux).
46    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
47    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
48    o new pkg: down_slope
49      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
50      - presently, modify T & S inland (dwnslp_calc_rho.F).
51        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
52      - implementation for ocean in P-coords not tested.
53      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
54    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
55      (to facilitate conversion of oceanic pkg to p-coordinate).
56    o change FIND_RHO to FIND_RHO_2D :
57      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
58    o new pkg: cheapaml
59    
60    checkpoint61b
61    o exch2:
62      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
63      - no longer depend on the order sequence (N,S,E,W).
64      - 3rd exchange no longer needed (tested with 24 tiles).
65      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
66      - exch_UV_A-grid readily available (but not yet tested).
67      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
68      (both are no longer needed) in exch_uv: no effect in forward run; but
69       get truncation error differences with adjoint exch.
70    o exch2:
71     - change index-bounds storage (moved from target to local tile,
72       more intuitive this way) ; rename/remove some variables.
73     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
74    
75    checkpoint61a
76    o exch2/matlab-topology-generator:
77      fix bug in index bounds for N-S internal exchange (hard to tell if this
78      had any effect on the solution).
79    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
80      is exceeded
81    o testreport: modify syntax of awk, so that it works also with
82      awk, and not only with nawk and gawk
83    
84    checkpoint61
85    o autodiff
86      Change default for TAF usage by removing argument '-nonew_arg'
87      This changes TAF subroutine argument list (ordering of active var.)
88      Omission of this flag leads to incompatibility w.r.t. TAMC
89      To restore TAMC-compatibility, need following modifs:
90      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
91      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
92      Tested TAF version is 1.9.22
93      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
94    
95    checkpoint60
96    --->>> This is the last checkpoint for which generating the adjoint
97    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
98    --->>> by default.
99    --->>> Future checkpoints will ommit this flag by default.
100    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
101    o pkg/grdchk: Add gradient check to etan0 perturbations.
102    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
103    o pkg/autodiff: more flexibility in zeroadj.
104      model/src: modifying do_oceanic_phys.F accordingly.
105    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
106    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
107      special setup of gmredi for which the adjoint is stable
108      enough for parameter optimization.
109  o bridging the gap between eddy stress and GM.  o bridging the gap between eddy stress and GM.
