4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
8      on CS-grid: no longer loosing mass.
9    o exf & curvilinear-grid: no longer modify longitude xC & xG.
10    o pkg/ggl90: fix sloppy output and fix a bug
11    o pkg/seaice: added SEAICEuseEVPpickup parameter
12      - Set to false in order to start EVP solver with
13        non-EVP pickup files when using SEAICEuseEVP
14      - fix sign error in diffusion in seaice_calc_rhs
15    
16    checkpoint58h_post
17    * Modifications for bottom topography control
18      o replace hFacC by _hFacC at various places
19      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
20      o add non-self-adjoint cg2d_nsa
21      o update autodiff support routines
22      o re-initialise hfac after ctrl_depth_ini
23      o works for 5x5 box, doesnt work for global_ocean.90x40x15
24    * Adding verification for 5x5 box (4-layer) bottom topography control
25    
26    checkpoint58g_post
27    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
28       used for mean seasonal cycle, mean diurnal cycle); add an example
29       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
30    o pkg/ggl90:
31      - add parameter (minimum surface kinetic energy)
32      - fix bug (avoiding division by zero)
33    o couple pkg/thsice to pkg/seaice:
34      - modify advection in seaice to accomodate new scalar fields to be advected
35      - only muliDimAdection scheme work with seaice/thsice
36      - mapping of thsice-variables to seaice-variables, back and forth
37      - does not break the verification experiments, but does not give the
38        desired results either
39    o pkg/seaice
40      - make (default) second order advection a bit less confusing?
41    
42    checkpoint58f_post
43    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
44      to pkg/seaice):
45      - new routines thsice_map_exf and thsice_get_exf provide the interface
46      - add an additional formal parameter to thsice_solve4temp
47    o pkg/exf:
48      - add new fields wspeed, snowprecip (to be able to couple to thsice)
49      - correct Stefan-Boltzmann constant
50      - new parameter for longwave surface emittance
51      - separate some stuff from exf_bulkformulae into new routines  
52        exf_radiation, exf_wind
53      - add new parameters and constants: longwave emissivity for ocean, ice
54        and snow, evaporation parameters over ice
55      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
56        either wind from stress or stress from wind
57    o pkg/thSIce:
58    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
59    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
60       and THSICE_CALC_THICKN
61    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
62    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
63      to make debugging easier.
64    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
65    o pkg/bulk_force:
66      - clean-up comments and parameters ;
67      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
68    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
69      generate new output for test-experiment: aim.5l_cs.thSI
70    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
71      testreport accordingly
72    
73    checkpoint58e_post
74    o SEAICE_CGRID adjoint done
75    o R_STAR adjoint implemented.
76      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
77      * need to sort out init. of h0facc, etc.
78    o Make pkg/profile fully independent of ecco,cost, etc. stuff
79      to be able to use it in pure forward.
80    
81    checkpoint58d_post
82    o upgrade simple test-experiment to tutorial example:
83     step.1: duplicate the experiment and (step.2) will remove the old copy.
84      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
85      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
86      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
87      tutorial_global_oce_biogeo    <- copy of dic_example
88      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
89      tutorial_plume_on_slope       <- copy of plume_on_slope
90      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
91      tutorial_global_oce_optim     <- empty for now (David ?)
92      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
93     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
94    o correct a sign problem in cost_scat.F
95    o obcs and ptracers: fix boundary conditions for advections schemes
96      with larger stencil
97    o thsice adjoint: start
98    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
99      completeness
100    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
101      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
102    o ptracers adjoint:
103      * avoid extensive recomputatations
104      * fix missing re-init. of gptr (missed by TAF)
105    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
106      me to turn off the excessive output to STDOUT that this package produces
107    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
108      and add those terms in Vector-Invariant formulation.
109    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
110      if the control period (xx_hfluxperiod etc) is 0
111    o in profiles pkg, clean routines and fix details
112    o in ecco pkg, reading ssh data:
113      fix problem in case the model does not start at iter0=0
114    o fix mnc-pickup/restart for ptracers
115    o new package prifiles:
116      code to compute profile-based cost by Gael Forget
117      (modifs in ecco, ctrl, autodiff)
118    o Benign bug fix in initialization (spotted by M. Mazloff) of
119      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
120    
121    checkpoint58c_post
122    o adjoint: finish NLFS adjoint and provide reference output in
123      verification/global_ocean.90x40x15/results_ad_nlfs
124    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
125      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
126      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
127      with SEAICE_CGRID defined.
128    o move calendarDumps from "data" to "data.cal" and clean-up the code
129      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
130    o add useEXF & useCAL flags (for now, set in hard-coded way)
131  o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum  o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
132    (were missing in NH mode, and wrong in quasihydrostatic mode).    (were missing in NH mode, and wrong in quasihydrostatic mode).
133    waiting for Chris updated version of calc_gw to add those CALLs.    waiting for Chris updated version of calc_gw to add those CALLs.
