5      ==============================      ==============================
6    
7    checkpoint61c
8    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
9      to add mass source/sink of fluid in the interior (3-D generalisation
10      of oceanic real-fresh water flux).
11    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
12    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
13    o new pkg: down_slope
14      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
15      - presently, modify T & S inland (dwnslp_calc_rho.F).
16        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
17      - implementation for ocean in P-coords not tested.
18      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
19    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
20      (to facilitate conversion of oceanic pkg to p-coordinate).
21    o change FIND_RHO to FIND_RHO_2D :
22      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
23    o new pkg: cheapaml
24    
25    checkpoint61b
26    o exch2:
27      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
28      - no longer depend on the order sequence (N,S,E,W).
29      - 3rd exchange no longer needed (tested with 24 tiles).
30      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
31      - exch_UV_A-grid readily available (but not yet tested).
32      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
33      (both are no longer needed) in exch_uv: no effect in forward run; but
34       get truncation error differences with adjoint exch.
35    o exch2:
36     - change index-bounds storage (moved from target to local tile,
37       more intuitive this way) ; rename/remove some variables.
38     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
39    
40    checkpoint61a
41    o exch2/matlab-topology-generator:
42      fix bug in index bounds for N-S internal exchange (hard to tell if this
43      had any effect on the solution).
44    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
45      is exceeded
46    o testreport: modify syntax of awk, so that it works also with
47      awk, and not only with nawk and gawk
48    
49    checkpoint61
50    o autodiff
51      Change default for TAF usage by removing argument '-nonew_arg'
52      This changes TAF subroutine argument list (ordering of active var.)
53      Omission of this flag leads to incompatibility w.r.t. TAMC
54      To restore TAMC-compatibility, need following modifs:
55      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
56      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
57      Tested TAF version is 1.9.22
58      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
59    
60    checkpoint60
61    --->>> This is the last checkpoint for which generating the adjoint
62    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
63    --->>> by default.
64    --->>> Future checkpoints will ommit this flag by default.
65    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
66    o pkg/grdchk: Add gradient check to etan0 perturbations.
67    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
68    o pkg/autodiff: more flexibility in zeroadj.
69      model/src: modifying do_oceanic_phys.F accordingly.
70    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
71    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
72      special setup of gmredi for which the adjoint is stable
73      enough for parameter optimization.
74    o bridging the gap between eddy stress and GM.
75      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
76          along with a change in CPP option (now ALLOW_EDDYPSI).
77      -> when using GM w/ GM_AdvForm:
78          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
79          is applied either in the tracer Eq. or in momentum Eq.
80          depending on data.gmredi (intro. GM_InMomAsStress).
81      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
82      The key modifications are in model/src/taueddy_external_forcing.F
83      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
84    
85    checkpoint59r
86    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
87      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
88      fix option to read coriolis(@ cell-corner) from files with CS-grid.
89    o pkg/mnc: add some attributes to standard 1D-coordinate variables
90  o pkg/diagnostics: enforce missing_value attribute for scalar variables at  o pkg/diagnostics: enforce missing_value attribute for scalar variables at
