5    
6  tag before changing staggerTimeStep  o more obcs stuff
7      - added obcs_external_fields_load as an alternative to the EXF-pkg option
8        for reading boundary values. This routine is called from
9        obcs_prescribe_read
10      - updated obcs_check
11    
12    checkpoint55c_post
13    o obcs stuff
14      - new runtime flags useOBCSprescribe, useOBCSbalance
15      - re-arranged obcs_calc
16      - moved exf_getobcs to obcs_prescibe_read
17        obcs_prescibe_read is called after ORLANSKI stuff
18        and independent of it (executable can contain all).
19      - updated obcs_check
20      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
21        These may be necessary only if tangential velocities are
22        prescribed at OB, not sure, needs testing.
23    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
24      which simplifies the calls and passes the ifc check-bounds test
25    
26    checkpoint55b_post
27    o add a 2D scalar, Z location, exchange_2 routine.
28    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
29      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
30      affects advect_cs results (for the wrong reason): update output.txt
31    o use a more standard discretization for biharmonic viscosity ;
32     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
33      affects results of dome set-up: update output.txt
34    o fix gad_advection.F (CubedSphere part), back to version 1.23
35    o fix bug in mom_vi_del2uv.F (CubedSphere part).
36    
37    checkpoint55a_post
38    o merged code to
39      * prescribe/read time-dependent open boundaries
40        (works in conjunction with exf, cal)
41      * sponge layer code for open boundaries
42      * each boundary N/S/E/W now has its own CPP option
43        (healthy for the adjoint)
44    
45    checkpoint55
46    o up-to-date adjoint of previous breaks
47      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
48      - global_ocean_ebm: adjoint still needs fix (TLM ok)
49      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
50      - carbon: * remove tr1-related adjoint verification
51                * add ptracer as control variable
52    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
53      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
54    
55    checkpoint54f_post
56    o in verification/carbin/ remove experiment related to
57      ALLOW_PASSIVE_TRACER (array tr1 etc)
58      code_ad/ input_ad/ results_ad
59    
60    o add two new packages
61      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
62        + subject to optimization (memory)
63      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
64        + subject to reordering (many GOTOs in the original code)
65        + so far opps is called for every (i,j) point, and then operates in
66          the vertical; one may want to reorder the scheme in order operate in
67          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
68          fields)
69    o overhaul of IO so that we now have flags for MDSIO and/or MNC
70      - all verification tests compile and run with linux_ia32_g77
71      - defaults are compatible with current input files--nothing
72        should change if you were not previously using MNC
73      - MNC output has been added in numerous places (eg. timeave)
74        but there are still a few writes not yet do-able with MNC
75        (this is in progress)
76      - flags now allow for either/or/both use of MDSIO and MNC and
77        documentation will soon follow
78      - numerous small formatting cleanups for ProTeX
79    o add version info (via BUILD_INFO.h) to MNC and stdout
80    
81    checkpoint54e_post
82    o add two new packages
83      - pp81 (Packanowski and Philander, 1981), Richardson number and
84        stratification dependent mixing
85      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
86      - these scheme operate in a similar manner as KPP (without ghat, of
87        course), however there is only one diffusivity that is used for both
88        temperature and salinity (and passive tracers)ç
89    o add offline package
90    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
91      provided by Stephanie Dutkiewicz
92    o genmake2: add ability to search for C compilers and cleanup test output
93      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
94    
95    checkpoint54d_post
96    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
97    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
98      leading to additional shift by 5 days each year of integration
99       (i.e. leading to considerable offset over the years)
100    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
101    o start with no AB and no initial filtering (staggerTimeStep):
102      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
103    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
104      (external loading & cpl import/export stay in forward_step.F)
105    o update coupling interface to work with new staggerTimeStep
106    o change MDSIO ptracers_pickup.
107    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
108    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
109    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
110    
111    checkpoint54c_post
112    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
113      this affects (truncation error) output.txt of test-exp:
114       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
115    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
116    o change Qnet to always be the net heat flux, (+upward).
117      affects (truncation error) output of natl_box exp.: updated
118    o define the max number of passive tracers in PTRACERS_SIZE.h
119    o start to test mnc routinely in exp0
120    o add sea-ice loading (sIceLoad) as a new forcing field.
121    
122    checkpoint54b_post
123    o add testreport "-j JOBS" option for parallel builds (tested and pretty
124       impressive on Altix and Opteron systems)
125    o diagnostics can now write NetCDF files through the mnc package
126    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
127    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
128    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
129      affects (truncation error) output of lab_sea & natl_box exp.: updated
130    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
131    
132    checkpoint54a_post
133    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
134    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
135    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
136    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
137      + internal_wave (shift in writing cg2d_ini_res)
138  checkpoint54a_pre  checkpoint54a_pre
139    
140  o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice  o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
