4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o exch2:
8     - change index-bounds storage (moved from target to local tile,
9       more intuitive this way) ; rename/remove some variables.
10     - change utils/exch2/matlab-topology-generator accordingly.
11    
12    checkpoint61a
13    o exch2/matlab-topology-generator:
14      fix bug in index bounds for N-S internal exchange (hard to tell if this
15      had any effect on the solution).
16    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
17      is exceeded
18    o testreport: modify syntax of awk, so that it works also with
19      awk, and not only with nawk and gawk
20    
21    checkpoint61
22    o autodiff
23      Change default for TAF usage by removing argument '-nonew_arg'
24      This changes TAF subroutine argument list (ordering of active var.)
25      Omission of this flag leads to incompatibility w.r.t. TAMC
26      To restore TAMC-compatibility, need following modifs:
27      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
28      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
29      Tested TAF version is 1.9.22
30      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
31    
32    checkpoint60
33    --->>> This is the last checkpoint for which generating the adjoint
34    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
35    --->>> by default.
36    --->>> Future checkpoints will ommit this flag by default.
37    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
38    o pkg/grdchk: Add gradient check to etan0 perturbations.
39    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
40    o pkg/autodiff: more flexibility in zeroadj.
41      model/src: modifying do_oceanic_phys.F accordingly.
42    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
43    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
44      special setup of gmredi for which the adjoint is stable
45      enough for parameter optimization.
46    o bridging the gap between eddy stress and GM.
47      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
48          along with a change in CPP option (now ALLOW_EDDYPSI).
49      -> when using GM w/ GM_AdvForm:
50          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
51          is applied either in the tracer Eq. or in momentum Eq.
52          depending on data.gmredi (intro. GM_InMomAsStress).
53      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
54      The key modifications are in model/src/taueddy_external_forcing.F
55      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
56    
57    checkpoint59r
58    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
59      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
60      fix option to read coriolis(@ cell-corner) from files with CS-grid.
61    o pkg/mnc: add some attributes to standard 1D-coordinate variables
62  o pkg/diagnostics: enforce missing_value attribute for scalar variables at  o pkg/diagnostics: enforce missing_value attribute for scalar variables at
63    mass points, when using mnc for output    mass points, when using mnc for output
