4      ==============================      ==============================
5    
6    checkpoint54e_post
7    o add two new packages
8      - pp81 (Packanowski and Philander, 1981), Richardson number and
9        stratification dependent mixing
10      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
11      - these scheme operate in a similar manner as KPP (without ghat, of
12        course), however there is only one diffusivity that is used for both
13        temperature and salinity (and passive tracers)ç
14    o add offline package
15    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
16      provided by Stephanie Dutkiewicz
17    o genmake2: add ability to search for C compilers and cleanup test output
18      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
19    
20    checkpoint54d_post
21    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
22    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
23      leading to additional shift by 5 days each year of integration
24       (i.e. leading to considerable offset over the years)
25    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
26    o start with no AB and no initial filtering (staggerTimeStep):
27      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
28    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
29      (external loading & cpl import/export stay in forward_step.F)
30    o update coupling interface to work with new staggerTimeStep
31    o change MDSIO ptracers_pickup.
32    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
33    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
34    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
35    
36    checkpoint54c_post
37    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
38      this affects (truncation error) output.txt of test-exp:
39       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
40    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
41    o change Qnet to always be the net heat flux, (+upward).
42      affects (truncation error) output of natl_box exp.: updated
43    o define the max number of passive tracers in PTRACERS_SIZE.h
44    o start to test mnc routinely in exp0
45    o add sea-ice loading (sIceLoad) as a new forcing field.
46    
47    checkpoint54b_post
48    o add testreport "-j JOBS" option for parallel builds (tested and pretty
49       impressive on Altix and Opteron systems)
50    o diagnostics can now write NetCDF files through the mnc package
51    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
52    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
53    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
54      affects (truncation error) output of lab_sea & natl_box exp.: updated
55    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
56    
57    checkpoint54a_post
58    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
59    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
60    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
61    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
62      + internal_wave (shift in writing cg2d_ini_res)
63    checkpoint54a_pre
64    
65    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
66      - modified verification/lab_sea and natl_box_adjoint accordingly
67    
68    checkpoint54
69    checkpoint53g_post
70    o prepare splitting of thermodynamics: store convect.counter in common block
71    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
72      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
73    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
74    o new parameter "nShapS": allow to treat differently S from T (nShapT)
75    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
76    o restore adjointability
77    
78    checkpoint53f_post
79    o modifications that affect AIM experiment results (update output.txt):
80      - no advection of S at top interface Nr (pkg/generic_advdiff)
81      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
82    o AIM pkg:
83      - include stability function into surf.Flux derivative relative to Tsurf
84      - calculate clear-sky radiation & surface temp. change (for diagnostics)
85    
86    checkpoint53e_post
87    o merged cylindrical coord configuration
88    o added rotating_tank experiment
89    checkpoint53e_pre
90    
91    checkpoint53d_post
92    o faulks upgraded: re-generate output.txt that have changed:
93       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
94    o Added Bryan and Lewis, 1979, vertical diffusivity profile
95    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
96    o added Sadourny discretization of Coriolis
97      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
98      - re-enabled use of omega3 (useAbsVorticity)
99    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
100      vector-invariant equations
101      - note: does *NOT* yet use same variable visc. for no-slip BC's.
102    o recoded the lateral boundary conditions for non-hydrostatic w, this time
103      hopefully without new bugs
104      - still to do: biharmonic friction for non-hydrostatic w
105    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
106    o regenerated output for global_ocean_ebm (using -ieee)
107    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
108      of mom_common/
109      - simple re-arrangement of instructions within computing loop
110    checkpoint53d_pre
111    
112    checkpoint53c_post
113    o new version of coupler for AIM+thSIce and Ocean models

115     - land: change Evaporation of snow
116     - aim with thSIce: fix bug in snow-precip.
