5      ==============================      ==============================
6    
7    checkpoint58k_post
8    o testreport:
9     - always build in dir. "build" (if not there, mkdir build instead of building
10       & running in input)
11     - run in dir run (if it exists), in build otherwise.
12     - call prepare_run (if input/prepare_run exists)
13     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
14    o pkg/exf modifications to interpolation and rotation routines for more
15       reasonable treatment of North Pole singularity: for tracers North Pole
16       value is set to northernmost zonal-mean value, for zonal velocity it is
17       set to zero, and for meridional velocity it is set to northernmost value.
18    o pkg/exf/exf_check_range.F
19     - add tile index to diagnostics and move stop statement to the very
20       end of the routine.
21    o pkg/diagnostics: (diagnostics_main_init.F)
22      define title of isomorphic variables according to the current config.
23    o pkg/thsice with pkg/seaice dynamics:
24    - fix domain of computation (interior only, required for exf) and do exchanges
25    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
26    o towards a standard way of dealing with multi-threading in MONITOR
27      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
28    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
29       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
30    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
31    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
32    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
33       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
34    o tracer advection:
35     - clean-up and simplify calc_common_factors.F
36     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
37       advection subroutine (but still not used within DST advection S/R)
38    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
39    
40    checkpoint58j_post
41    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
42      from file (collects calls previously in FORWARD_STEP)
43    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
44    o adjoint store dir. adjusted accordingly
45    o genmake2
46      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
47    
48    checkpoint58i_post
49    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
50      on wind stress (SEAICEstressFactor defaults to 1.)
51    o Total number of Timers is finite (<=40): comment out 2 non-essential one
52      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
53    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
54      on CS-grid: no longer loosing mass.
55    o exf & curvilinear-grid: no longer modify longitude xC & xG.
56    o pkg/ggl90: fix sloppy output and fix a bug
57    o pkg/seaice: added SEAICEuseEVPpickup parameter
58      - Set to false in order to start EVP solver with
59        non-EVP pickup files when using SEAICEuseEVP
60      - fix sign error in diffusion in seaice_calc_rhs
61    
62    checkpoint58h_post
63    * Modifications for bottom topography control
64      o replace hFacC by _hFacC at various places
65      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
66      o add non-self-adjoint cg2d_nsa
67      o update autodiff support routines
68      o re-initialise hfac after ctrl_depth_ini
69      o works for 5x5 box, doesnt work for global_ocean.90x40x15
70    * Adding verification for 5x5 box (4-layer) bottom topography control
71    
72    checkpoint58g_post
73    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
74       used for mean seasonal cycle, mean diurnal cycle); add an example
75       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
76    o pkg/ggl90:
77      - add parameter (minimum surface kinetic energy)
78      - fix bug (avoiding division by zero)
79    o couple pkg/thsice to pkg/seaice:
80      - modify advection in seaice to accomodate new scalar fields to be advected
81      - only muliDimAdection scheme work with seaice/thsice
82      - mapping of thsice-variables to seaice-variables, back and forth
83      - does not break the verification experiments, but does not give the
84        desired results either
85    o pkg/seaice
86      - make (default) second order advection a bit less confusing?
87    
88    checkpoint58f_post
89    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
90      to pkg/seaice):
91      - new routines thsice_map_exf and thsice_get_exf provide the interface
92      - add an additional formal parameter to thsice_solve4temp
93    o pkg/exf:
94      - add new fields wspeed, snowprecip (to be able to couple to thsice)
95      - correct Stefan-Boltzmann constant
96      - new parameter for longwave surface emittance
97      - separate some stuff from exf_bulkformulae into new routines  
98        exf_radiation, exf_wind
99      - add new parameters and constants: longwave emissivity for ocean, ice
100        and snow, evaporation parameters over ice
101      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
102        either wind from stress or stress from wind
103    o pkg/thSIce:
104    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
105    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
106       and THSICE_CALC_THICKN
107    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
108    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
109      to make debugging easier.
110    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
111    o pkg/bulk_force:
112      - clean-up comments and parameters ;
113      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
114    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
115      generate new output for test-experiment: aim.5l_cs.thSI
116    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
117      testreport accordingly
118

152      me to turn off the excessive output to STDOUT that this package produces
153    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
