4      ==============================      ==============================
5    
6    checkpoint55
7    o up-to-date adjoint of previous breaks
8      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
9      - global_ocean_ebm: adjoint still needs fix (TLM ok)
10      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
11      - carbon: * remove tr1-related adjoint verification
12                * add ptracer as control variable
13    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
14      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
15    
16    checkpoint54f_post
17    o in verification/carbin/ remove experiment related to
18      ALLOW_PASSIVE_TRACER (array tr1 etc)
19      code_ad/ input_ad/ results_ad
20    
21    o add two new packages
22      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
23        + subject to optimization (memory)
24      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
25        + subject to reordering (many GOTOs in the original code)
26        + so far opps is called for every (i,j) point, and then operates in
27          the vertical; one may want to reorder the scheme in order operate in
28          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
29          fields)
30    o overhaul of IO so that we now have flags for MDSIO and/or MNC
31      - all verification tests compile and run with linux_ia32_g77
32      - defaults are compatible with current input files--nothing
33        should change if you were not previously using MNC
34      - MNC output has been added in numerous places (eg. timeave)
35        but there are still a few writes not yet do-able with MNC
36        (this is in progress)
37      - flags now allow for either/or/both use of MDSIO and MNC and
38        documentation will soon follow
39      - numerous small formatting cleanups for ProTeX
40    o add version info (via BUILD_INFO.h) to MNC and stdout
41    
42    checkpoint54e_post
43    o add two new packages
44      - pp81 (Packanowski and Philander, 1981), Richardson number and
45        stratification dependent mixing
46      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
47      - these scheme operate in a similar manner as KPP (without ghat, of
48        course), however there is only one diffusivity that is used for both
49        temperature and salinity (and passive tracers)ç
50    o add offline package
51    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
52      provided by Stephanie Dutkiewicz
53    o genmake2: add ability to search for C compilers and cleanup test output
54      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
55    
56    checkpoint54d_post
57    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
58    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
59      leading to additional shift by 5 days each year of integration
60       (i.e. leading to considerable offset over the years)
61    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
62    o start with no AB and no initial filtering (staggerTimeStep):
63      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
64    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
65      (external loading & cpl import/export stay in forward_step.F)
66    o update coupling interface to work with new staggerTimeStep
67    o change MDSIO ptracers_pickup.
68    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
69    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
70    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
71    
72    checkpoint54c_post
73    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
74      this affects (truncation error) output.txt of test-exp:
75       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
76    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
77    o change Qnet to always be the net heat flux, (+upward).
78      affects (truncation error) output of natl_box exp.: updated
79    o define the max number of passive tracers in PTRACERS_SIZE.h
80    o start to test mnc routinely in exp0
81    o add sea-ice loading (sIceLoad) as a new forcing field.
82    
83    checkpoint54b_post
84    o add testreport "-j JOBS" option for parallel builds (tested and pretty
85       impressive on Altix and Opteron systems)
86    o diagnostics can now write NetCDF files through the mnc package
87    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
88    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
89    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
90      affects (truncation error) output of lab_sea & natl_box exp.: updated
91    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
92    
93    checkpoint54a_post
94    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
95    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
96    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
97    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
98      + internal_wave (shift in writing cg2d_ini_res)
99    checkpoint54a_pre
100    
101    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
102      - modified verification/lab_sea and natl_box_adjoint accordingly
103    
104    checkpoint54
105    checkpoint53g_post
106    o prepare splitting of thermodynamics: store convect.counter in common block
107    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
108      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
109    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
110    o new parameter "nShapS": allow to treat differently S from T (nShapT)
111    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
112    o restore adjointability
113    
114    checkpoint53f_post
115    o modifications that affect AIM experiment results (update output.txt):
116      - no advection of S at top interface Nr (pkg/generic_advdiff)
117      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
118    o AIM pkg:
119      - include stability function into surf.Flux derivative relative to Tsurf
120      - calculate clear-sky radiation & surface temp. change (for diagnostics)
121    
122    checkpoint53e_post
123    o merged cylindrical coord configuration
124    o added rotating_tank experiment
125    checkpoint53e_pre
126    
127    checkpoint53d_post

129       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
130    o Added Bryan and Lewis, 1979, vertical diffusivity profile
131    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
132    o added Sadourny discretization of Coriolis
133      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
134      - re-enabled use of omega3 (useAbsVorticity)
135    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
136      vector-invariant equations
137      - note: does *NOT* yet use same variable visc. for no-slip BC's.
138    o recoded the lateral boundary conditions for non-hydrostatic w, this time
139      hopefully without new bugs
140      - still to do: biharmonic friction for non-hydrostatic w
141    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
142    o regenerated output for global_ocean_ebm (using -ieee)
143  o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation  o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
144    of mom_common/    of mom_common/
