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