3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o remove all the *_ioinc flags and replace with the single global
7      outputTypesInclusive flag
8    o allow to set a vertical profile of vertical diffusivity for T & S
9    
10    checkpoint55g_post
11    o Renaming carbon AD experiments to comply with testreport conventions
12    o Updating adjoint of Held-Suarez hs94.1x64x5
13    o Fixing directives for non-ECCO forward_step, after ECCO directives
14      have been fixed to avoid recomp. of do_oceanic_phys
15      Works well for global_ocean.90x40x15,
16      but recomp. issue remains for carbon
17    o Updating adjoint output for natl_box_adjoint after
18      pkg/ecco has been modified (see taga c55d_post)
19    
20    checkpoint55f_post
21    o rename to timeave_init_fixed
22    
23    checkpoint55e_post
24    o some delicate re-shuffle of store directives to avoid one
25      extra call of do_oceanic_physics
26      affects ecco_the_main_loop.F, do_oceanic_physics.F
27      checkpoint_lev1_directives.h
28    o NB: this may break global_ocean adjoint temporarily,
29      but it is clear how to fix it. Will do later, need this now.
30    
31    checkpoint55d_post
32    o ECCO specific cost function terms (up-to-date with 1x1 runs)
33    o ecco_cost_weights is modified to 1x1 runs
34    o modifs to allow observations to be read in as
35      single file or yearly files
36    o enable to read exf forcing fields as either
37      single file or yearly files (flag useExfYearlyFields)
38    checkpoint55d_pre
39    
40    o switch between 2-level and 3-level checkpointing
41    o add ability of MNC to write local and "partial" (eg. 2D slices where
42      the full 3D field is never actually stored) arrays to NetCDF files
43      with the correct (that is, the complete multi-dimensional) set of
44      array indicies
45      - used in mom_vecinv() to write the diagFreq output
46      - tested (demonstrated) in verification/aim.5l_cs
47    o further mnc-ification
48      - add verification/lab_sea to the list with mnc setups
49      - fix undefined mnc v-names in cd_code
50      - add kpp to mnc output (both snapshot and timeave)
51    o non-hydrostatic code
52      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
53        in calc_gw.F
54      - defaults to viscAh
55      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
56        friction or Leith) in non-hydrostatic mode, as long as there is
57        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
58    o pkg/cost
59      extend simple cost functions to treat time mean quantities
60      (T,U,V) via cost_accumulate_state from cost_tile
61    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
62        be 2 times larger than the minimum size the advection scheme requires.
63        now get a perfect conservation of salt in advect_cs test-exp (updated)
64    o GGL90 (Gaspar's TKE mixed layer)
65      - add horizontal diffusion of TKE, requires exchanges in
66        do_fields_blocking_exchanges, horizontal diffusivity is zero by
67        default. In OPA there is no horizontal diffusion of TKE but the
68        mixing coefficients are computed from a horizontal average of TKE of
69        6 points or so. I think that diffusion has a little more physical
70        justification.
71      - clean up ggl90_calc in the hope of reducing memory usage (this hope
72        was in vain)
73      - mask tke-variable in ggl90_init
74    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
75    o fix biharmonic diffusion on CS-grid.
76    o more obcs stuff
77      - added obcs_external_fields_load as an alternative to the EXF-pkg option
78        for reading boundary values. This routine is called from
79        obcs_prescribe_read
80      - updated obcs_check
81      - changed sponge layer relaxation parameter units for days to seconds
82      - turned off sponge layer by default
83      - changed argument list of OBCS_CALC to myTime+deltaTclock
84      - fixed about 35 bugs in obcs_external_fields_load
85    
86    checkpoint55c_post
87    o obcs stuff
88      - new runtime flags useOBCSprescribe, useOBCSbalance
89      - re-arranged obcs_calc
90      - moved exf_getobcs to obcs_prescibe_read
91        obcs_prescibe_read is called after ORLANSKI stuff
92        and independent of it (executable can contain all).
93      - updated obcs_check
94      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
95        These may be necessary only if tangential velocities are
96        prescribed at OB, not sure, needs testing.
97    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
98      which simplifies the calls and passes the ifc check-bounds test
99    
100    checkpoint55b_post
101    o add a 2D scalar, Z location, exchange_2 routine.
102    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
103      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
104      affects advect_cs results (for the wrong reason): update output.txt
105    o use a more standard discretization for biharmonic viscosity ;
106     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
107      affects results of dome set-up: update output.txt
108    o fix gad_advection.F (CubedSphere part), back to version 1.23
109    o fix bug in mom_vi_del2uv.F (CubedSphere part).
110    
111    checkpoint55a_post
112    o merged code to
113      * prescribe/read time-dependent open boundaries
114        (works in conjunction with exf, cal)
115      * sponge layer code for open boundaries
116      * each boundary N/S/E/W now has its own CPP option
117        (healthy for the adjoint)
118    
119    checkpoint55
120    o up-to-date adjoint of previous breaks
121      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
122      - global_ocean_ebm: adjoint still needs fix (TLM ok)
123      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
124      - carbon: * remove tr1-related adjoint verification
125                * add ptracer as control variable
126    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
127      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
128    
129    checkpoint54f_post
130    o in verification/carbin/ remove experiment related to
131      ALLOW_PASSIVE_TRACER (array tr1 etc)
132      code_ad/ input_ad/ results_ad
133    
134    o add two new packages
135      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
136        + subject to optimization (memory)
137      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
138        + subject to reordering (many GOTOs in the original code)
139        + so far opps is called for every (i,j) point, and then operates in
140          the vertical; one may want to reorder the scheme in order operate in
141          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
142          fields)
143    o overhaul of IO so that we now have flags for MDSIO and/or MNC
144      - all verification tests compile and run with linux_ia32_g77
145      - defaults are compatible with current input files--nothing
146        should change if you were not previously using MNC
147      - MNC output has been added in numerous places (eg. timeave)
148        but there are still a few writes not yet do-able with MNC
149        (this is in progress)
150      - flags now allow for either/or/both use of MDSIO and MNC and
151        documentation will soon follow
152      - numerous small formatting cleanups for ProTeX
153    o add version info (via BUILD_INFO.h) to MNC and stdout
154    
155    checkpoint54e_post
156    o add two new packages
157      - pp81 (Packanowski and Philander, 1981), Richardson number and
158        stratification dependent mixing
159      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
160      - these scheme operate in a similar manner as KPP (without ghat, of
161        course), however there is only one diffusivity that is used for both
162        temperature and salinity (and passive tracers)ç
163    o add offline package
164    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
165      provided by Stephanie Dutkiewicz
166    o genmake2: add ability to search for C compilers and cleanup test output
167      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
168    
169    checkpoint54d_post
170    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
171    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
172      leading to additional shift by 5 days each year of integration
173       (i.e. leading to considerable offset over the years)
174    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
175    o start with no AB and no initial filtering (staggerTimeStep):
176      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
177    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
178      (external loading & cpl import/export stay in forward_step.F)
179    o update coupling interface to work with new staggerTimeStep
180    o change MDSIO ptracers_pickup.
181    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
182    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
183    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
184    
185    checkpoint54c_post
186    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
187      this affects (truncation error) output.txt of test-exp:
188       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
189    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
190    o change Qnet to always be the net heat flux, (+upward).
191      affects (truncation error) output of natl_box exp.: updated
192    o define the max number of passive tracers in PTRACERS_SIZE.h
193    o start to test mnc routinely in exp0
194    o add sea-ice loading (sIceLoad) as a new forcing field.
195    
196    checkpoint54b_post
197    o add testreport "-j JOBS" option for parallel builds (tested and pretty
198       impressive on Altix and Opteron systems)
199    o diagnostics can now write NetCDF files through the mnc package
200    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
201    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
202    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
203      affects (truncation error) output of lab_sea & natl_box exp.: updated
204    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
205    
206    checkpoint54a_post
207    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
208    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
209    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
210    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
211      + internal_wave (shift in writing cg2d_ini_res)
212    checkpoint54a_pre
213    
214    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
215      - modified verification/lab_sea and natl_box_adjoint accordingly
216    
217    checkpoint54
218    checkpoint53g_post
219    o prepare splitting of thermodynamics: store convect.counter in common block
220    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
221      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
222    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
223    o new parameter "nShapS": allow to treat differently S from T (nShapT)
224    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
225    o restore adjointability
226    
227    checkpoint53f_post
228    o modifications that affect AIM experiment results (update output.txt):
229      - no advection of S at top interface Nr (pkg/generic_advdiff)
230      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
231    o AIM pkg:
232      - include stability function into surf.Flux derivative relative to Tsurf
233      - calculate clear-sky radiation & surface temp. change (for diagnostics)
234    
235    checkpoint53e_post
236    o merged cylindrical coord configuration
237    o added rotating_tank experiment
238    checkpoint53e_pre
239    
240    checkpoint53d_post
241    o faulks upgraded: re-generate output.txt that have changed:
242       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
243    o Added Bryan and Lewis, 1979, vertical diffusivity profile
244    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
245    o added Sadourny discretization of Coriolis
246      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
247      - re-enabled use of omega3 (useAbsVorticity)
248    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
249      vector-invariant equations
250      - note: does *NOT* yet use same variable visc. for no-slip BC's.
251    o recoded the lateral boundary conditions for non-hydrostatic w, this time
252      hopefully without new bugs
253      - still to do: biharmonic friction for non-hydrostatic w
254    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
255    o regenerated output for global_ocean_ebm (using -ieee)
256    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
257      of mom_common/
258      - simple re-arrangement of instructions within computing loop
259    checkpoint53d_pre
260    
261    checkpoint53c_post
262    o new version of coupler for AIM+thSIce and Ocean models
263     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
264     - land: change Evaporation of snow
265     - aim with thSIce: fix bug in snow-precip.
266    o changes to calc_gw.F
267     - bug fix for w^2 term near the bottom boundary
268     - (hopefully) improve the lateral slip boundary condtions for use with
269        partial/looped cells
270      - because the bug fix changes two verification experiments anyway (exp5
271        and plume on slope), change the lateral boundary condition from half slip
272        to the value of no_slip_sides
273    o ebm package wasnt quite up to the parallel task. Fixed that.
274    o Adjoint of EBM package + verification
275      * TLM OK
276      * ADM not sufficient accuracy yet (needs further testing)
277    
278    checkpoint53b_post
279    o Commiting new energy balance model to repository
280      * package is pkg/ebm
281      * verif. is verification/global_ocean_ebm
282      * references are in ebm_driver.F
283    C      * X. Wang, P. Stone and J. Marotzke, 1999:
284    C        Global thermohaline circulation. Part I:
285    C        Sensitivity to atmospheric moisture transport.
286    C        J. Climate 12(1), 71-82
287    C      * X. Wang, P. Stone and J. Marotzke, 1999:
288    C        Global thermohaline circulation. Part II:
289    C        Sensitivity with interactive transport.
290    C        J. Climate 12(1), 83-91
291    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
292    C        Destabilization of the thermohaline circulation
293    C        by atmospheric eddy transports.
294    C        J. Climate 7(12), 1870-1882
295    o Will need long integration testing.
296    checkpoint53b_pre
297    
298    o created pkg/mom_common in preparation for variable viscosity code
299    o renamed and split ini_mnc_io
300    o pkg/land: only liquid water can diffuse or run-off
301    o AIM using land: soil wetness availability account for snow
302    o added printMapIncludesZeros to EEPARMS namelist
303    
304    checkpoint53a_post
305    o restore TAMC compatiility for exf_constants.h
306      (no usage of _d in .h)
307    o Additional storing in KPP in an attempt to fix
308      TAMC problem with adjoint of KPP code.
309      (no success...)
310      Identical code works fine with TAF.
311    o Fixed verification/natl_box_adjoint experiments.
312      Initial conditions for Experiments 4 and 5 are now
313      set to "SEAICE_initialHEFF=0", which is more reasonable,
314      and hence gives results closer to that of Experiment 2.
315      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
316    
317    checkpoint53
318    o stable checkpoint with up to date adjoint
319      TLM tests only run for 1st grdchk at the moment. Its unclear if
320      this is a code problem or a problem with resetting code for g_
321      variables that is being autogenerated wrong.
322      Otherwise:
323       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
324       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
325         are both still in chaos following their security messes.
326    
327    checkpoint52n_post
328    o various build (mostly genmake2) changes including:
329      - ability to build/run more easily within Cygwin and MacOS X
330      - more complicated Makefiles with a stronger dependence on Gnu Make
331    o pkg/seaice modifications
332      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
333        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
334        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
335      - changed proxy for geostrophic velocity and updated
336        verification/lab_sea/results/* accordingly
337      - removed ADI dynamic solver from pkg/seaice
338      - replaced all occurrences of 1/CSTICE or 1/CSUICE
339        they caused a segmentation fault under certain circumstances
340      - removed unused field WATR
341    o bug fix in exf-package:
342      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
343         now reflect that.
344    o small fixes in the cal-package:
345      - set reference date to first of January for the 'model'-calendar
346      - failing of cal_CheckDate in cal_FullDate now actually results in a
347        warning
348    o small modifications in exf-package to increase flexibility:
349      - change climtempfreeze from a constant to a runtime parameter that
350        is specified in data.exf_clim (default = -1.9)
351      - introduce runtime parameter windstressmax (default = 2.0) that is
352        specified in data.exf
353    o fix in pkg/thsice:
354      - update Evap (Tsf changes) to be consistent with Latent heat flux
355      - maintain snow precipitation unchanged (even if Tsf >=0).
356     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
357    
358    checkpoint52m_post
359    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
360      this does not change any of the results, because myIter=0 in swfrac always
361      lead to jwtype=2 (the default anyway), but the call makes little sense
362      as a default
363    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
364    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
365      atmospheric model (AIM) to use it ; add a "slab ocean" component.
366    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
367    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
368    o extending useSingleCpuIO option to work with new exch2 I/O format
369      - old-style, missing-tile I/O is still accessible by defining CPP
370        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
371    o monitor package can write to NetCDF files and/or STDOUT
372    o fix re-definition bug in MNC_GRID_INIT_ALL()
373    o doc/api_reference added
374      - a framework for building an API Reference Manual using all
375        the "protex" comments embedded in the code
376      - see pkg/generic_advdiff, pkg/mnc for examples
377  o MNC:  o MNC:
378    - make myThid the last argument for all subroutines    - make myThid the last argument for all subroutines
379    - new default for the grid files: NO halos    - new default for the grid files: NO halos
