3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o add version info (via BUILD_INFO.h) to MNC and stdout
7    
8    checkpoint54e_post
9    o add two new packages
10      - pp81 (Packanowski and Philander, 1981), Richardson number and
11        stratification dependent mixing
12      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
13      - these scheme operate in a similar manner as KPP (without ghat, of
14        course), however there is only one diffusivity that is used for both
15        temperature and salinity (and passive tracers)ç
16    o add offline package
17    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
18      provided by Stephanie Dutkiewicz
19    o genmake2: add ability to search for C compilers and cleanup test output
20      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
21    
22    checkpoint54d_post
23    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
24    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
25      leading to additional shift by 5 days each year of integration
26       (i.e. leading to considerable offset over the years)
27    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
28    o start with no AB and no initial filtering (staggerTimeStep):
29      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
30    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
31      (external loading & cpl import/export stay in forward_step.F)
32    o update coupling interface to work with new staggerTimeStep
33    o change MDSIO ptracers_pickup.
34    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
35    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
36    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
37    
38    checkpoint54c_post
39    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
40      this affects (truncation error) output.txt of test-exp:
41       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
42    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
43    o change Qnet to always be the net heat flux, (+upward).
44      affects (truncation error) output of natl_box exp.: updated
45    o define the max number of passive tracers in PTRACERS_SIZE.h
46    o start to test mnc routinely in exp0
47    o add sea-ice loading (sIceLoad) as a new forcing field.
48    
49    checkpoint54b_post
50    o add testreport "-j JOBS" option for parallel builds (tested and pretty
51       impressive on Altix and Opteron systems)
52    o diagnostics can now write NetCDF files through the mnc package
53    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
54    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
55    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
56      affects (truncation error) output of lab_sea & natl_box exp.: updated
57    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
58    
59    checkpoint54a_post
60    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
61    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
62    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
63    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
64      + internal_wave (shift in writing cg2d_ini_res)
65    checkpoint54a_pre
66    
67    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
68      - modified verification/lab_sea and natl_box_adjoint accordingly
69    
70    checkpoint54
71    checkpoint53g_post
72    o prepare splitting of thermodynamics: store convect.counter in common block
73    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
74      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
75    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
76    o new parameter "nShapS": allow to treat differently S from T (nShapT)
77    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
78    o restore adjointability
79    
80    checkpoint53f_post
81    o modifications that affect AIM experiment results (update output.txt):
82      - no advection of S at top interface Nr (pkg/generic_advdiff)
83      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
84    o AIM pkg:
85      - include stability function into surf.Flux derivative relative to Tsurf
86      - calculate clear-sky radiation & surface temp. change (for diagnostics)
87    
88    checkpoint53e_post
89    o merged cylindrical coord configuration
90    o added rotating_tank experiment
91    checkpoint53e_pre
92    
93    checkpoint53d_post
94    o faulks upgraded: re-generate output.txt that have changed:
95       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
96    o Added Bryan and Lewis, 1979, vertical diffusivity profile
97    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
98    o added Sadourny discretization of Coriolis
99      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
100      - re-enabled use of omega3 (useAbsVorticity)
101    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
102      vector-invariant equations
103      - note: does *NOT* yet use same variable visc. for no-slip BC's.
104    o recoded the lateral boundary conditions for non-hydrostatic w, this time
105      hopefully without new bugs
106      - still to do: biharmonic friction for non-hydrostatic w
107    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
108    o regenerated output for global_ocean_ebm (using -ieee)
109    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
110      of mom_common/
111      - simple re-arrangement of instructions within computing loop
112    checkpoint53d_pre
113    
114    checkpoint53c_post
115    o new version of coupler for AIM+thSIce and Ocean models
116     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
117     - land: change Evaporation of snow
118     - aim with thSIce: fix bug in snow-precip.
119    o changes to calc_gw.F
120     - bug fix for w^2 term near the bottom boundary
121     - (hopefully) improve the lateral slip boundary condtions for use with
122        partial/looped cells
123      - because the bug fix changes two verification experiments anyway (exp5
124        and plume on slope), change the lateral boundary condition from half slip
125        to the value of no_slip_sides
126    o ebm package wasnt quite up to the parallel task. Fixed that.
127    o Adjoint of EBM package + verification
128      * TLM OK
129      * ADM not sufficient accuracy yet (needs further testing)
130    
131    checkpoint53b_post
132    o Commiting new energy balance model to repository
133      * package is pkg/ebm
134      * verif. is verification/global_ocean_ebm
135      * references are in ebm_driver.F
136    C      * X. Wang, P. Stone and J. Marotzke, 1999:
137    C        Global thermohaline circulation. Part I:

146    C        by atmospheric eddy transports.

148    o Will need long integration testing.
149    checkpoint53b_pre
150    
151    o created pkg/mom_common in preparation for variable viscosity code
152    o renamed and split ini_mnc_io
153  o pkg/land: only liquid water can diffuse or run-off  o pkg/land: only liquid water can diffuse or run-off
154  o AIM using land: soil wetness availability account for snow  o AIM using land: soil wetness availability account for snow
