3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
7      which simplifies the calls and passes the ifc check-bounds test
8    
9    checkpoint55b_post
10    o add a 2D scalar, Z location, exchange_2 routine.
11    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
12      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
13      affects advect_cs results (for the wrong reason): update output.txt
14    o use a more standard discretization for biharmonic viscosity ;
15     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
16      affects results of dome set-up: update output.txt
17    o fix gad_advection.F (CubedSphere part), back to version 1.23
18    o fix bug in mom_vi_del2uv.F (CubedSphere part).
19    
20    checkpoint55a_post
21    o merged code to
22      * prescribe/read time-dependent open boundaries
23        (works in conjunction with exf, cal)
24      * sponge layer code for open boundaries
25      * each boundary N/S/E/W now has its own CPP option
26        (healthy for the adjoint)
27    
28    checkpoint55
29    o up-to-date adjoint of previous breaks
30      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
31      - global_ocean_ebm: adjoint still needs fix (TLM ok)
32      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
33      - carbon: * remove tr1-related adjoint verification
34                * add ptracer as control variable
35    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
36      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
37    
38    checkpoint54f_post
39    o in verification/carbin/ remove experiment related to
40      ALLOW_PASSIVE_TRACER (array tr1 etc)
41      code_ad/ input_ad/ results_ad
42    
43    o add two new packages
44      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
45        + subject to optimization (memory)
46      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
47        + subject to reordering (many GOTOs in the original code)
48        + so far opps is called for every (i,j) point, and then operates in
49          the vertical; one may want to reorder the scheme in order operate in
50          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
51          fields)
52    o overhaul of IO so that we now have flags for MDSIO and/or MNC
53      - all verification tests compile and run with linux_ia32_g77
54      - defaults are compatible with current input files--nothing
55        should change if you were not previously using MNC
56      - MNC output has been added in numerous places (eg. timeave)
57        but there are still a few writes not yet do-able with MNC
58        (this is in progress)
59      - flags now allow for either/or/both use of MDSIO and MNC and
60        documentation will soon follow
61      - numerous small formatting cleanups for ProTeX
62    o add version info (via BUILD_INFO.h) to MNC and stdout
63    
64    checkpoint54e_post
65    o add two new packages
66      - pp81 (Packanowski and Philander, 1981), Richardson number and
67        stratification dependent mixing
68      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
69      - these scheme operate in a similar manner as KPP (without ghat, of
70        course), however there is only one diffusivity that is used for both
71        temperature and salinity (and passive tracers)ç
72    o add offline package
73    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
74      provided by Stephanie Dutkiewicz
75    o genmake2: add ability to search for C compilers and cleanup test output
76      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
77    
78    checkpoint54d_post
79    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
80    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
81      leading to additional shift by 5 days each year of integration
82       (i.e. leading to considerable offset over the years)
83    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
84    o start with no AB and no initial filtering (staggerTimeStep):
85      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
86    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
87      (external loading & cpl import/export stay in forward_step.F)
88    o update coupling interface to work with new staggerTimeStep
89    o change MDSIO ptracers_pickup.
90    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
91    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
92    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
93    
94    checkpoint54c_post
95    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
96      this affects (truncation error) output.txt of test-exp:
97       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
98    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
99    o change Qnet to always be the net heat flux, (+upward).
100      affects (truncation error) output of natl_box exp.: updated
101    o define the max number of passive tracers in PTRACERS_SIZE.h
102    o start to test mnc routinely in exp0
103    o add sea-ice loading (sIceLoad) as a new forcing field.
104    
105    checkpoint54b_post
106    o add testreport "-j JOBS" option for parallel builds (tested and pretty
107       impressive on Altix and Opteron systems)
108    o diagnostics can now write NetCDF files through the mnc package
109    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
110    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
111    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
112      affects (truncation error) output of lab_sea & natl_box exp.: updated
113    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
114    
115    checkpoint54a_post
116    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
117    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
118    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
119    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
120      + internal_wave (shift in writing cg2d_ini_res)
121    checkpoint54a_pre
122    
123    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
124      - modified verification/lab_sea and natl_box_adjoint accordingly
125    
126    checkpoint54
127    checkpoint53g_post
128    o prepare splitting of thermodynamics: store convect.counter in common block
129    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
130      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
131    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
132    o new parameter "nShapS": allow to treat differently S from T (nShapT)
133    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
134    o restore adjointability
135    
136    checkpoint53f_post
137    o modifications that affect AIM experiment results (update output.txt):
138      - no advection of S at top interface Nr (pkg/generic_advdiff)
139      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
140    o AIM pkg:
141      - include stability function into surf.Flux derivative relative to Tsurf
142      - calculate clear-sky radiation & surface temp. change (for diagnostics)
143    
144    checkpoint53e_post
145    o merged cylindrical coord configuration
146    o added rotating_tank experiment
147    checkpoint53e_pre
148    
149    checkpoint53d_post
150    o faulks upgraded: re-generate output.txt that have changed:
151       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
152    o Added Bryan and Lewis, 1979, vertical diffusivity profile
153    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
154    o added Sadourny discretization of Coriolis
155      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
156      - re-enabled use of omega3 (useAbsVorticity)
157    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
158      vector-invariant equations
159      - note: does *NOT* yet use same variable visc. for no-slip BC's.
160    o recoded the lateral boundary conditions for non-hydrostatic w, this time
161      hopefully without new bugs
162      - still to do: biharmonic friction for non-hydrostatic w
163    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
164    o regenerated output for global_ocean_ebm (using -ieee)
165    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
166      of mom_common/
167      - simple re-arrangement of instructions within computing loop
168    checkpoint53d_pre
169    
170    checkpoint53c_post
171    o new version of coupler for AIM+thSIce and Ocean models
172     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
173     - land: change Evaporation of snow
174     - aim with thSIce: fix bug in snow-precip.
175    o changes to calc_gw.F
176     - bug fix for w^2 term near the bottom boundary
177     - (hopefully) improve the lateral slip boundary condtions for use with
178        partial/looped cells
179      - because the bug fix changes two verification experiments anyway (exp5
180        and plume on slope), change the lateral boundary condition from half slip
181        to the value of no_slip_sides
182    o ebm package wasnt quite up to the parallel task. Fixed that.
183    o Adjoint of EBM package + verification
184      * TLM OK
185      * ADM not sufficient accuracy yet (needs further testing)
186    
187    checkpoint53b_post
