4      ==============================      ==============================
5    o Compute the non-local term using either KPP vertical diffusivity (=default)
6       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
7    
8    checkpoint55h_post
9    o add verification test "vermix"
10    o remove all the *_ioinc flags and replace with the single global
11      outputTypesInclusive flag
12    o allow to set a vertical profile of vertical diffusivity for T & S
13    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
14    o useMNC moved from data.mnc to data.pkg
15    
16    checkpoint55g_post
17    o Renaming carbon AD experiments to comply with testreport conventions
18    o Updating adjoint of Held-Suarez hs94.1x64x5
19    o Fixing directives for non-ECCO forward_step, after ECCO directives
20      have been fixed to avoid recomp. of do_oceanic_phys
21      Works well for global_ocean.90x40x15,
22      but recomp. issue remains for carbon
23    o Updating adjoint output for natl_box_adjoint after
24      pkg/ecco has been modified (see taga c55d_post)
25    
26    checkpoint55f_post
27    o rename to timeave_init_fixed
28    
29    checkpoint55e_post
30    o some delicate re-shuffle of store directives to avoid one
31      extra call of do_oceanic_physics
32      affects ecco_the_main_loop.F, do_oceanic_physics.F
33      checkpoint_lev1_directives.h
34    o NB: this may break global_ocean adjoint temporarily,
35      but it is clear how to fix it. Will do later, need this now.
36    
37    checkpoint55d_post
38    o ECCO specific cost function terms (up-to-date with 1x1 runs)
39    o ecco_cost_weights is modified to 1x1 runs
40    o modifs to allow observations to be read in as
41      single file or yearly files
42    o enable to read exf forcing fields as either
43      single file or yearly files (flag useExfYearlyFields)
44    checkpoint55d_pre
45    
46    o switch between 2-level and 3-level checkpointing
47    o add ability of MNC to write local and "partial" (eg. 2D slices where
48      the full 3D field is never actually stored) arrays to NetCDF files
49      with the correct (that is, the complete multi-dimensional) set of
50      array indicies
51      - used in mom_vecinv() to write the diagFreq output
52      - tested (demonstrated) in verification/aim.5l_cs
53    o further mnc-ification
54      - add verification/lab_sea to the list with mnc setups
55      - fix undefined mnc v-names in cd_code
56      - add kpp to mnc output (both snapshot and timeave)
57    o non-hydrostatic code
58      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
59        in calc_gw.F
60      - defaults to viscAh
61      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
62        friction or Leith) in non-hydrostatic mode, as long as there is
63        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
64    o pkg/cost
65      extend simple cost functions to treat time mean quantities
66      (T,U,V) via cost_accumulate_state from cost_tile
67    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
68        be 2 times larger than the minimum size the advection scheme requires.
69        now get a perfect conservation of salt in advect_cs test-exp (updated)
70    o GGL90 (Gaspar's TKE mixed layer)
71      - add horizontal diffusion of TKE, requires exchanges in
72        do_fields_blocking_exchanges, horizontal diffusivity is zero by
73        default. In OPA there is no horizontal diffusion of TKE but the
74        mixing coefficients are computed from a horizontal average of TKE of
75        6 points or so. I think that diffusion has a little more physical
76        justification.
77      - clean up ggl90_calc in the hope of reducing memory usage (this hope
78        was in vain)
79      - mask tke-variable in ggl90_init
80    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
81    o fix biharmonic diffusion on CS-grid.
82    o more obcs stuff
83      - added obcs_external_fields_load as an alternative to the EXF-pkg option
84        for reading boundary values. This routine is called from
85        obcs_prescribe_read
86      - updated obcs_check
87      - changed sponge layer relaxation parameter units for days to seconds
88      - turned off sponge layer by default
89      - changed argument list of OBCS_CALC to myTime+deltaTclock
90      - fixed about 35 bugs in obcs_external_fields_load
91    
92    checkpoint55c_post
93    o obcs stuff
94      - new runtime flags useOBCSprescribe, useOBCSbalance
95      - re-arranged obcs_calc
96      - moved exf_getobcs to obcs_prescibe_read
97        obcs_prescibe_read is called after ORLANSKI stuff
98        and independent of it (executable can contain all).
99      - updated obcs_check
100      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
101        These may be necessary only if tangential velocities are
102        prescribed at OB, not sure, needs testing.
103    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
104      which simplifies the calls and passes the ifc check-bounds test
105    
106    checkpoint55b_post
107    o add a 2D scalar, Z location, exchange_2 routine.
108    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
109      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
110      affects advect_cs results (for the wrong reason): update output.txt
111    o use a more standard discretization for biharmonic viscosity ;
112     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
113      affects results of dome set-up: update output.txt
114    o fix gad_advection.F (CubedSphere part), back to version 1.23
115    o fix bug in mom_vi_del2uv.F (CubedSphere part).
116    
117    checkpoint55a_post
118    o merged code to
119      * prescribe/read time-dependent open boundaries
120        (works in conjunction with exf, cal)
121      * sponge layer code for open boundaries
122      * each boundary N/S/E/W now has its own CPP option
123        (healthy for the adjoint)
124    
125    checkpoint55
126    o up-to-date adjoint of previous breaks
127      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
128      - global_ocean_ebm: adjoint still needs fix (TLM ok)
129      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
130      - carbon: * remove tr1-related adjoint verification
131                * add ptracer as control variable
132    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
133      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
134    
135    checkpoint54f_post
136    o in verification/carbin/ remove experiment related to
137      ALLOW_PASSIVE_TRACER (array tr1 etc)
138      code_ad/ input_ad/ results_ad
139    
140    o add two new packages
141      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
142        + subject to optimization (memory)
143      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
144        + subject to reordering (many GOTOs in the original code)
145        + so far opps is called for every (i,j) point, and then operates in
146          the vertical; one may want to reorder the scheme in order operate in
147          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
148          fields)
149    o overhaul of IO so that we now have flags for MDSIO and/or MNC
150      - all verification tests compile and run with linux_ia32_g77
151      - defaults are compatible with current input files--nothing
152        should change if you were not previously using MNC
153      - MNC output has been added in numerous places (eg. timeave)
154        but there are still a few writes not yet do-able with MNC
155        (this is in progress)
156      - flags now allow for either/or/both use of MDSIO and MNC and
157        documentation will soon follow
158      - numerous small formatting cleanups for ProTeX
159    o add version info (via BUILD_INFO.h) to MNC and stdout
160    
161    checkpoint54e_post
162    o add two new packages
163      - pp81 (Packanowski and Philander, 1981), Richardson number and
164        stratification dependent mixing
165      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
166      - these scheme operate in a similar manner as KPP (without ghat, of
167        course), however there is only one diffusivity that is used for both
168        temperature and salinity (and passive tracers)ç
169    o add offline package
170    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
171      provided by Stephanie Dutkiewicz
172    o genmake2: add ability to search for C compilers and cleanup test output
173      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
174    
175    checkpoint54d_post
176    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
177    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
178      leading to additional shift by 5 days each year of integration
179       (i.e. leading to considerable offset over the years)
180    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
181    o start with no AB and no initial filtering (staggerTimeStep):
182      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
183    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
184      (external loading & cpl import/export stay in forward_step.F)
185    o update coupling interface to work with new staggerTimeStep
186    o change MDSIO ptracers_pickup.
187    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
188    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
189    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
190    
191    checkpoint54c_post
192    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
193      this affects (truncation error) output.txt of test-exp:
194       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
195    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
196    o change Qnet to always be the net heat flux, (+upward).
197      affects (truncation error) output of natl_box exp.: updated
198    o define the max number of passive tracers in PTRACERS_SIZE.h
199    o start to test mnc routinely in exp0
200    o add sea-ice loading (sIceLoad) as a new forcing field.
201    
202    checkpoint54b_post
203    o add testreport "-j JOBS" option for parallel builds (tested and pretty
204       impressive on Altix and Opteron systems)
205    o diagnostics can now write NetCDF files through the mnc package
206    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
207    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
208    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
209      affects (truncation error) output of lab_sea & natl_box exp.: updated
210    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
211    
212  checkpoint54a_post  checkpoint54a_post
213  o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).  o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
