4      ==============================      ==============================
5    o use a more standard discretization for biharmonic viscosity ;
6     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
7      affects results of dome set-up: update output.txt
8    o fix gad_advection.F (CubedSphere part), back to version 1.23
9    o fix bug in mom_vi_del2uv.F (CubedSphere part).
10    
11    checkpoint55a_post
12    o merged code to
13      * prescribe/read time-dependent open boundaries
14        (works in conjunction with exf, cal)
15      * sponge layer code for open boundaries
16      * each boundary N/S/E/W now has its own CPP option
17        (healthy for the adjoint)
18    
19    checkpoint55
20    o up-to-date adjoint of previous breaks
21      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
22      - global_ocean_ebm: adjoint still needs fix (TLM ok)
23      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
24      - carbon: * remove tr1-related adjoint verification
25                * add ptracer as control variable
26    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
27      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
28    
29    checkpoint54f_post
30    o in verification/carbin/ remove experiment related to
31      ALLOW_PASSIVE_TRACER (array tr1 etc)
32      code_ad/ input_ad/ results_ad
33    
34    o add two new packages
35      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
36        + subject to optimization (memory)
37      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
38        + subject to reordering (many GOTOs in the original code)
39        + so far opps is called for every (i,j) point, and then operates in
40          the vertical; one may want to reorder the scheme in order operate in
41          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
42          fields)
43    o overhaul of IO so that we now have flags for MDSIO and/or MNC
44      - all verification tests compile and run with linux_ia32_g77
45      - defaults are compatible with current input files--nothing
46        should change if you were not previously using MNC
47      - MNC output has been added in numerous places (eg. timeave)
48        but there are still a few writes not yet do-able with MNC
49        (this is in progress)
50      - flags now allow for either/or/both use of MDSIO and MNC and
51        documentation will soon follow
52      - numerous small formatting cleanups for ProTeX
53    o add version info (via BUILD_INFO.h) to MNC and stdout
54    
55    checkpoint54e_post
56    o add two new packages
57      - pp81 (Packanowski and Philander, 1981), Richardson number and
58        stratification dependent mixing
59      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
60      - these scheme operate in a similar manner as KPP (without ghat, of
61        course), however there is only one diffusivity that is used for both
62        temperature and salinity (and passive tracers)ç
63    o add offline package
64    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
65      provided by Stephanie Dutkiewicz
66    o genmake2: add ability to search for C compilers and cleanup test output
67      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
68    
69    checkpoint54d_post
70    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
71    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
72      leading to additional shift by 5 days each year of integration
73       (i.e. leading to considerable offset over the years)
74    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
75    o start with no AB and no initial filtering (staggerTimeStep):
76      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
77    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
78      (external loading & cpl import/export stay in forward_step.F)
79    o update coupling interface to work with new staggerTimeStep
80    o change MDSIO ptracers_pickup.
81    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
82    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
83    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
84    
85    checkpoint54c_post
86    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
87      this affects (truncation error) output.txt of test-exp:
88       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
89    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
90    o change Qnet to always be the net heat flux, (+upward).
91      affects (truncation error) output of natl_box exp.: updated
92    o define the max number of passive tracers in PTRACERS_SIZE.h
93    o start to test mnc routinely in exp0
94    o add sea-ice loading (sIceLoad) as a new forcing field.
95    
96    checkpoint54b_post
97    o add testreport "-j JOBS" option for parallel builds (tested and pretty
98       impressive on Altix and Opteron systems)
99    o diagnostics can now write NetCDF files through the mnc package
100    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
101    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
102    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
103      affects (truncation error) output of lab_sea & natl_box exp.: updated
104    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
105    
106    checkpoint54a_post
107    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
108    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
109    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
110    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
111      + internal_wave (shift in writing cg2d_ini_res)
112    checkpoint54a_pre
113    
114    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
115      - modified verification/lab_sea and natl_box_adjoint accordingly
116    
117    checkpoint54
118    checkpoint53g_post
119    o prepare splitting of thermodynamics: store convect.counter in common block
120    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
121      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
122  o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection  o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
123  o new parameter "nShapS": allow to treat differently S from T (nShapT)  o new parameter "nShapS": allow to treat differently S from T (nShapT)
124  o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)  o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
125    o restore adjointability
126    
127  checkpoint53f_post  checkpoint53f_post
128  o modifications that affect AIM experiment results (update output.txt):  o modifications that affect AIM experiment results (update output.txt):
