4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/thsice with pkg/seaice dynamics:
8    - fix domain of computation (interior only, required for exf) and do exchanges
9    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
10    o towards a standard way of dealing with multi-threading in MONITOR
11      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
12    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
13       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
14    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
15    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
16    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
17       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
18    o tracer advection:
19     - clean-up and simplify calc_common_factors.F
20     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
21       advection subroutine (but still not used within DST advection S/R)
22    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
23    
24    checkpoint58j_post
25    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
26      from file (collects calls previously in FORWARD_STEP)
27    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
28    o adjoint store dir. adjusted accordingly
29    o genmake2
30      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
31    
32    checkpoint58i_post
33    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
34      on wind stress (SEAICEstressFactor defaults to 1.)
35    o Total number of Timers is finite (<=40): comment out 2 non-essential one
36      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
37    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
38      on CS-grid: no longer loosing mass.
39    o exf & curvilinear-grid: no longer modify longitude xC & xG.
40    o pkg/ggl90: fix sloppy output and fix a bug
41    o pkg/seaice: added SEAICEuseEVPpickup parameter
42      - Set to false in order to start EVP solver with
43        non-EVP pickup files when using SEAICEuseEVP
44      - fix sign error in diffusion in seaice_calc_rhs
45    
46    checkpoint58h_post
47    * Modifications for bottom topography control
48      o replace hFacC by _hFacC at various places
49      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
50      o add non-self-adjoint cg2d_nsa
51      o update autodiff support routines
52      o re-initialise hfac after ctrl_depth_ini
53      o works for 5x5 box, doesnt work for global_ocean.90x40x15
54    * Adding verification for 5x5 box (4-layer) bottom topography control
55    
56    checkpoint58g_post
57    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
58       used for mean seasonal cycle, mean diurnal cycle); add an example
59       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
60    o pkg/ggl90:
61      - add parameter (minimum surface kinetic energy)
62      - fix bug (avoiding division by zero)
63    o couple pkg/thsice to pkg/seaice:
64      - modify advection in seaice to accomodate new scalar fields to be advected
65      - only muliDimAdection scheme work with seaice/thsice
66      - mapping of thsice-variables to seaice-variables, back and forth
67      - does not break the verification experiments, but does not give the
68        desired results either
69    o pkg/seaice
70      - make (default) second order advection a bit less confusing?
71    
72    checkpoint58f_post
73    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
74      to pkg/seaice):
75      - new routines thsice_map_exf and thsice_get_exf provide the interface
76      - add an additional formal parameter to thsice_solve4temp
77    o pkg/exf:
78      - add new fields wspeed, snowprecip (to be able to couple to thsice)
79      - correct Stefan-Boltzmann constant
80      - new parameter for longwave surface emittance
81      - separate some stuff from exf_bulkformulae into new routines  
82        exf_radiation, exf_wind
83      - add new parameters and constants: longwave emissivity for ocean, ice
84        and snow, evaporation parameters over ice
85      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
86        either wind from stress or stress from wind
87    o pkg/thSIce:
88    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
89    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
90       and THSICE_CALC_THICKN
91    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
92    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
93      to make debugging easier.
94    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
95    o pkg/bulk_force:
96      - clean-up comments and parameters ;
97      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
98    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
99      generate new output for test-experiment: aim.5l_cs.thSI
100    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
101      testreport accordingly
102    
103    checkpoint58e_post
104    o SEAICE_CGRID adjoint done
105    o R_STAR adjoint implemented.
106      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
107      * need to sort out init. of h0facc, etc.
108    o Make pkg/profile fully independent of ecco,cost, etc. stuff
109      to be able to use it in pure forward.
110    
111  checkpoint58d_post  checkpoint58d_post
112  o upgrade simple test-experiment to tutorial example:  o upgrade simple test-experiment to tutorial example:
113   step.1: duplicate the experiment and (step.2) will remove the old copy.   step.1: duplicate the experiment and (step.2) will remove the old copy.
