6    
7    checkpoint61
8    o autodiff
9      Change default for TAF usage by removing argument '-nonew_arg'
10      This changes TAF subroutine argument list (ordering of active var.)
11      Omission of this flag leads to incompatibility w.r.t. TAMC
12      To restore TAMC-compatibility, need following modifs:
13      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
14      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
15      Tested TAF version is 1.9.22
16      N.B.: exch2 hand-written adjoint code currently not TAMC compatible

22    --->>> Future checkpoints will ommit this flag by default.
23    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
24    o pkg/grdchk: Add gradient check to etan0 perturbations.
25    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
26    o pkg/autodiff: more flexibility in zeroadj.
27      model/src: modifying do_oceanic_phys.F accordingly.
28    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
29    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
30      special setup of gmredi for which the adjoint is stable
31      enough for parameter optimization.
32    o bridging the gap between eddy stress and GM.
33      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
34          along with a change in CPP option (now ALLOW_EDDYPSI).
35      -> when using GM w/ GM_AdvForm:
36          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
37          is applied either in the tracer Eq. or in momentum Eq.
38          depending on data.gmredi (intro. GM_InMomAsStress).
39      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
40      The key modifications are in model/src/taueddy_external_forcing.F
41      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F

43    checkpoint59r
44    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
45      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
46      fix option to read coriolis(@ cell-corner) from files with CS-grid.
