3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
7      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
8    o add consistent build directories and .cvsignore files to verification
9    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
10    o make all subroutines 30 or less characters in length for certain older
11      compilers to work (a thorough search only turns up two routines in
12      pkg/ptracers)
13    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
14      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
15    
16    checkpoint55i_post
17    o change arrays for total vertical diffusivity (2.D if explicit,
18      3.D if implicit) ; each ptracer uses its own background value.
19    o added mnc/NetCDF output capability to ocn_compon_interf
20      - added bits to verification/cpl_aim+ocn so that it can run on
21        ITRDA and other clusters without the mpirun "-wd" option
22    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
23      configuration
24    o give MNC the ability to create additional files rather than
25      exceeding a specified file size limit "MNC_MAX_FILESIZE"
26      - the default is just less than 2GB which is a practical limit
27        on many systems
28    o Compute the non-local term using either KPP vertical diffusivity (=default)
29       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
30    
31    checkpoint55h_post
32    o add verification test "vermix"
33    o remove all the *_ioinc flags and replace with the single global
34      outputTypesInclusive flag
35    o allow to set a vertical profile of vertical diffusivity for T & S
36    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
37    o useMNC moved from data.mnc to data.pkg
38    
39    checkpoint55g_post
40    o Renaming carbon AD experiments to comply with testreport conventions
41    o Updating adjoint of Held-Suarez hs94.1x64x5
42    o Fixing directives for non-ECCO forward_step, after ECCO directives
43      have been fixed to avoid recomp. of do_oceanic_phys
44      Works well for global_ocean.90x40x15,
45      but recomp. issue remains for carbon
46    o Updating adjoint output for natl_box_adjoint after
47      pkg/ecco has been modified (see taga c55d_post)
48    
49    checkpoint55f_post
50    o rename to timeave_init_fixed
51    
52    checkpoint55e_post
53    o some delicate re-shuffle of store directives to avoid one
54      extra call of do_oceanic_physics
55      affects ecco_the_main_loop.F, do_oceanic_physics.F
56      checkpoint_lev1_directives.h
57    o NB: this may break global_ocean adjoint temporarily,
58      but it is clear how to fix it. Will do later, need this now.
59    
60    checkpoint55d_post
61    o ECCO specific cost function terms (up-to-date with 1x1 runs)
62    o ecco_cost_weights is modified to 1x1 runs
63    o modifs to allow observations to be read in as
64      single file or yearly files
65    o enable to read exf forcing fields as either
66      single file or yearly files (flag useExfYearlyFields)
67    checkpoint55d_pre
68    
69    o switch between 2-level and 3-level checkpointing
70    o add ability of MNC to write local and "partial" (eg. 2D slices where
71      the full 3D field is never actually stored) arrays to NetCDF files
72      with the correct (that is, the complete multi-dimensional) set of
73      array indicies
74      - used in mom_vecinv() to write the diagFreq output
75      - tested (demonstrated) in verification/aim.5l_cs
76    o further mnc-ification
77      - add verification/lab_sea to the list with mnc setups
78      - fix undefined mnc v-names in cd_code
79      - add kpp to mnc output (both snapshot and timeave)
80    o non-hydrostatic code
81      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
82        in calc_gw.F
83      - defaults to viscAh
84      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
85        friction or Leith) in non-hydrostatic mode, as long as there is
86        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
87    o pkg/cost
88      extend simple cost functions to treat time mean quantities
89      (T,U,V) via cost_accumulate_state from cost_tile
90    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
91        be 2 times larger than the minimum size the advection scheme requires.
92        now get a perfect conservation of salt in advect_cs test-exp (updated)
93    o GGL90 (Gaspar's TKE mixed layer)
94      - add horizontal diffusion of TKE, requires exchanges in
95        do_fields_blocking_exchanges, horizontal diffusivity is zero by
96        default. In OPA there is no horizontal diffusion of TKE but the
97        mixing coefficients are computed from a horizontal average of TKE of
98        6 points or so. I think that diffusion has a little more physical
99        justification.
100      - clean up ggl90_calc in the hope of reducing memory usage (this hope
101        was in vain)
102      - mask tke-variable in ggl90_init
103    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
104    o fix biharmonic diffusion on CS-grid.
105    o more obcs stuff
106      - added obcs_external_fields_load as an alternative to the EXF-pkg option
107        for reading boundary values. This routine is called from
108        obcs_prescribe_read
109      - updated obcs_check
110      - changed sponge layer relaxation parameter units for days to seconds
111      - turned off sponge layer by default
112      - changed argument list of OBCS_CALC to myTime+deltaTclock
113      - fixed about 35 bugs in obcs_external_fields_load
114    
115    checkpoint55c_post
116    o obcs stuff
117      - new runtime flags useOBCSprescribe, useOBCSbalance
118      - re-arranged obcs_calc
119      - moved exf_getobcs to obcs_prescibe_read
120        obcs_prescibe_read is called after ORLANSKI stuff
121        and independent of it (executable can contain all).
122      - updated obcs_check
123      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
124        These may be necessary only if tangential velocities are
125        prescribed at OB, not sure, needs testing.
126    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
127      which simplifies the calls and passes the ifc check-bounds test
128    
129    checkpoint55b_post
130    o add a 2D scalar, Z location, exchange_2 routine.
131    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
132      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
133      affects advect_cs results (for the wrong reason): update output.txt
134    o use a more standard discretization for biharmonic viscosity ;
135     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
136      affects results of dome set-up: update output.txt
137    o fix gad_advection.F (CubedSphere part), back to version 1.23
138    o fix bug in mom_vi_del2uv.F (CubedSphere part).
139    
140    checkpoint55a_post
141    o merged code to
142      * prescribe/read time-dependent open boundaries
143        (works in conjunction with exf, cal)
144      * sponge layer code for open boundaries
145      * each boundary N/S/E/W now has its own CPP option
146        (healthy for the adjoint)
147    
148    checkpoint55
149    o up-to-date adjoint of previous breaks
150      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
151      - global_ocean_ebm: adjoint still needs fix (TLM ok)
152      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
153      - carbon: * remove tr1-related adjoint verification
154                * add ptracer as control variable
155    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
156      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
157    
158    checkpoint54f_post
159    o in verification/carbin/ remove experiment related to
160      ALLOW_PASSIVE_TRACER (array tr1 etc)
161      code_ad/ input_ad/ results_ad
162    
163    o add two new packages
164      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
165        + subject to optimization (memory)
166      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
167        + subject to reordering (many GOTOs in the original code)
168        + so far opps is called for every (i,j) point, and then operates in
169          the vertical; one may want to reorder the scheme in order operate in
170          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
171          fields)
172    o overhaul of IO so that we now have flags for MDSIO and/or MNC
173      - all verification tests compile and run with linux_ia32_g77
174      - defaults are compatible with current input files--nothing
175        should change if you were not previously using MNC
176      - MNC output has been added in numerous places (eg. timeave)
177        but there are still a few writes not yet do-able with MNC
178        (this is in progress)
179      - flags now allow for either/or/both use of MDSIO and MNC and
180        documentation will soon follow
181      - numerous small formatting cleanups for ProTeX
182    o add version info (via BUILD_INFO.h) to MNC and stdout
183    
184    checkpoint54e_post
185    o add two new packages
186      - pp81 (Packanowski and Philander, 1981), Richardson number and
187        stratification dependent mixing
188      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
189      - these scheme operate in a similar manner as KPP (without ghat, of
190        course), however there is only one diffusivity that is used for both
191        temperature and salinity (and passive tracers)ç
192    o add offline package
193    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
194      provided by Stephanie Dutkiewicz
195    o genmake2: add ability to search for C compilers and cleanup test output
196      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
197    
198    checkpoint54d_post
199    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
200    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
201      leading to additional shift by 5 days each year of integration
202       (i.e. leading to considerable offset over the years)
203    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
204    o start with no AB and no initial filtering (staggerTimeStep):
205      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
206    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
207      (external loading & cpl import/export stay in forward_step.F)
208    o update coupling interface to work with new staggerTimeStep
209    o change MDSIO ptracers_pickup.
210    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
211    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
212    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
213    
214    checkpoint54c_post
215    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
216      this affects (truncation error) output.txt of test-exp:
217       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
218    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
219    o change Qnet to always be the net heat flux, (+upward).
220      affects (truncation error) output of natl_box exp.: updated
221    o define the max number of passive tracers in PTRACERS_SIZE.h
222    o start to test mnc routinely in exp0
223    o add sea-ice loading (sIceLoad) as a new forcing field.
224    
225    checkpoint54b_post
226    o add testreport "-j JOBS" option for parallel builds (tested and pretty
227       impressive on Altix and Opteron systems)
228    o diagnostics can now write NetCDF files through the mnc package
229    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
230    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
231    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
232      affects (truncation error) output of lab_sea & natl_box exp.: updated
233    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
234    
235    checkpoint54a_post
236    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
237    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
238    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
239    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
240      + internal_wave (shift in writing cg2d_ini_res)
241    checkpoint54a_pre
242    
243    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
244      - modified verification/lab_sea and natl_box_adjoint accordingly
245    
246    checkpoint54
247    checkpoint53g_post
248    o prepare splitting of thermodynamics: store convect.counter in common block
249    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
250      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
251    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
252    o new parameter "nShapS": allow to treat differently S from T (nShapT)
253    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
254    o restore adjointability
255    
256    checkpoint53f_post
257    o modifications that affect AIM experiment results (update output.txt):
258      - no advection of S at top interface Nr (pkg/generic_advdiff)
259      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
260    o AIM pkg:
261      - include stability function into surf.Flux derivative relative to Tsurf
262      - calculate clear-sky radiation & surface temp. change (for diagnostics)
263    
264    checkpoint53e_post
265    o merged cylindrical coord configuration
266    o added rotating_tank experiment
267    checkpoint53e_pre
268    
269    checkpoint53d_post
270    o faulks upgraded: re-generate output.txt that have changed:
271       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
272    o Added Bryan and Lewis, 1979, vertical diffusivity profile
273    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
274    o added Sadourny discretization of Coriolis
275      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
276      - re-enabled use of omega3 (useAbsVorticity)
277    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
278      vector-invariant equations
279      - note: does *NOT* yet use same variable visc. for no-slip BC's.
280    o recoded the lateral boundary conditions for non-hydrostatic w, this time
281      hopefully without new bugs
282      - still to do: biharmonic friction for non-hydrostatic w
283    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
284    o regenerated output for global_ocean_ebm (using -ieee)
285    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
286      of mom_common/
287      - simple re-arrangement of instructions within computing loop
288    checkpoint53d_pre
289    
290    checkpoint53c_post
291    o new version of coupler for AIM+thSIce and Ocean models
292     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
293     - land: change Evaporation of snow
294     - aim with thSIce: fix bug in snow-precip.
295    o changes to calc_gw.F
296     - bug fix for w^2 term near the bottom boundary
297     - (hopefully) improve the lateral slip boundary condtions for use with
298        partial/looped cells
299      - because the bug fix changes two verification experiments anyway (exp5
300        and plume on slope), change the lateral boundary condition from half slip
301        to the value of no_slip_sides
302    o ebm package wasnt quite up to the parallel task. Fixed that.
303    o Adjoint of EBM package + verification
304      * TLM OK
305      * ADM not sufficient accuracy yet (needs further testing)
306    
307    checkpoint53b_post
308    o Commiting new energy balance model to repository
309      * package is pkg/ebm
310      * verif. is verification/global_ocean_ebm
311      * references are in ebm_driver.F
312    C      * X. Wang, P. Stone and J. Marotzke, 1999:
313    C        Global thermohaline circulation. Part I:
314    C        Sensitivity to atmospheric moisture transport.
315    C        J. Climate 12(1), 71-82
316    C      * X. Wang, P. Stone and J. Marotzke, 1999:
317    C        Global thermohaline circulation. Part II:
318    C        Sensitivity with interactive transport.
319    C        J. Climate 12(1), 83-91
320    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
321    C        Destabilization of the thermohaline circulation
322    C        by atmospheric eddy transports.
323    C        J. Climate 7(12), 1870-1882
324    o Will need long integration testing.
325    checkpoint53b_pre
326    
327    o created pkg/mom_common in preparation for variable viscosity code
328    o renamed and split ini_mnc_io
329    o pkg/land: only liquid water can diffuse or run-off
330    o AIM using land: soil wetness availability account for snow
331    o added printMapIncludesZeros to EEPARMS namelist
332    
333    checkpoint53a_post
334    o restore TAMC compatiility for exf_constants.h
335      (no usage of _d in .h)
336    o Additional storing in KPP in an attempt to fix
337      TAMC problem with adjoint of KPP code.
338      (no success...)
339      Identical code works fine with TAF.
340    o Fixed verification/natl_box_adjoint experiments.
341      Initial conditions for Experiments 4 and 5 are now
342      set to "SEAICE_initialHEFF=0", which is more reasonable,
343      and hence gives results closer to that of Experiment 2.
344      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
345    
346    checkpoint53
347    o stable checkpoint with up to date adjoint
348      TLM tests only run for 1st grdchk at the moment. Its unclear if
349      this is a code problem or a problem with resetting code for g_
350      variables that is being autogenerated wrong.
351      Otherwise:
352       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
353       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
354         are both still in chaos following their security messes.
355    
356    checkpoint52n_post
357    o various build (mostly genmake2) changes including:
358      - ability to build/run more easily within Cygwin and MacOS X
359      - more complicated Makefiles with a stronger dependence on Gnu Make
360    o pkg/seaice modifications
361      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
362        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
363        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
364      - changed proxy for geostrophic velocity and updated
365        verification/lab_sea/results/* accordingly
366      - removed ADI dynamic solver from pkg/seaice
367      - replaced all occurrences of 1/CSTICE or 1/CSUICE
368        they caused a segmentation fault under certain circumstances
369      - removed unused field WATR
370    o bug fix in exf-package:
371      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
372         now reflect that.
373    o small fixes in the cal-package:
374      - set reference date to first of January for the 'model'-calendar
375      - failing of cal_CheckDate in cal_FullDate now actually results in a
376        warning
377    o small modifications in exf-package to increase flexibility:
378      - change climtempfreeze from a constant to a runtime parameter that
379        is specified in data.exf_clim (default = -1.9)
380      - introduce runtime parameter windstressmax (default = 2.0) that is
381        specified in data.exf
382    o fix in pkg/thsice:
383      - update Evap (Tsf changes) to be consistent with Latent heat flux
384      - maintain snow precipitation unchanged (even if Tsf >=0).
385     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
386    
387    checkpoint52m_post
388    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
389      this does not change any of the results, because myIter=0 in swfrac always
390      lead to jwtype=2 (the default anyway), but the call makes little sense
391      as a default
392    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
393    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow

399        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
400    o monitor package can write to NetCDF files and/or STDOUT
401    o fix re-definition bug in MNC_GRID_INIT_ALL()
402    o doc/api_reference added
403      - a framework for building an API Reference Manual using all
404        the "protex" comments embedded in the code
405      - see pkg/generic_advdiff, pkg/mnc for examples
406    o MNC:
407      - make myThid the last argument for all subroutines
408      - new default for the grid files: NO halos
409      - add useMNC and other run-time flags
410      - separate per-file-group handling of the unlimited dimension
411      - early initialization of MNC w/ flags read at the eeboot stage
412        and lookup tables set in initialize_fixed
413      - write all MNC output to a freshly-created directory
414    o thermodynamics sea-ice (thsice) is now tested with testreport.
415    o test exp. advect_cs: use the standard cs32 grid ; update output.
416    o Added functionality to grdchk:
417      pick global i,j,k position (or nearest wet) where to perform check.
418    
419    checkpoint52l_post
420    o new land formulation:
421      a) use ground enthalpy as prognostic variable to ensure exact
422         energy conservation.
423      b) account for water temperature and for latent heat of freezing
424         in all processes (rain, run-off, ground storage)
425      c) compute surface and ground temperature implicitly.
426    o aim_v23 modification for new land model:
427      a) Treat separately land / ocean / sea-ice surface fluxes
428         to allow implicit computation of land & sea-ice surface temp.
429      b) add snow precipitation.
430    checkpoint52l_pre

441    o exf: Adding simple range check routine for exf fields after read
442    
443    checkpoint52k_post
444    o removed top-level directory "diags"
445      - we migrated these functions to pkg/timeave a long time ago
446    o fixed bug introduced in pkg/monitor
447    o accuracy ctrlprec = 32 insuffient for gradient checks using
448      averaged fields (I/O via cost_averages)
449      -> use ctrl.h in active_file*.F to control I/O precision.
450    o paramter list of CALL ADTHE_MAIN_LOOP
451    o added initial do_the_model_io to ecco
452    o set all ...Freq to zero after cost_final
453      taveFreq, dumpFreq, pChkptFreq
454    o MAIN and ECCO differentiability restored
455    
456    checkpoint52j_post
457    o fix nchklev in tamc.h for global_ocean...
458    o Bringing flow and store directives up-to-date
459    o Really weird thing!
460      call do_the_model_io from the_main_loop with parameters
461      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
462      TAF places a faulty re-call of initialise_varia
463      after cost_final call which should not be there!
464    checkpoint52j_pre
465    
466    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
467      error messages
468    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src

484    checkpoint52i_pre
485    
486    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
487      the old pkg/aim).
488    
489    checkpoint52h_pre
490    o shortened offending lines in exch2_send_rx?.template
491    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator

494      old grid files, moved CPP_EEMACROS.h to pkg/exch2
495    o added useSingleCPUIO flag to monitor.F and mon_out.F
496    o added temporary hack for sea-ice dynamics on the cube:
497      metric terms are ignored and it is assumed that
498      there is no sea-ice on cube faces 1, 2, 4, and 5.
499    
500    checkpoint52f_post
501    o added exch2 cube routines to pkg/exch2
502    o modified hs94.cs-32x32x5 to use it
503    o added new grid files to hs94.cs-32x32x5
504    checkpoint52f_pre
505    
506    checkpoint52e_post
507    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
508      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
509    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
510      to work with implicit vertical advection and AB ;
511    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
512    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
513     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
514    checkpoint52e_pre
515    
516    o fix bug in impldiff when Nr=1 or Nr=2.
517    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
518    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
519    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
520      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
521    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
522    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
523    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
524    
525    checkpoint52d_post
526    o re-tiled many expts to allow comparison in multi-processor mode
527      - updated output accordingly
528      - changed hs94.128x64x5 to use intial T from file rather than use the
529        random number generator
530    o add infrastructure in model routines for fizhi and gridalt packages
531    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
532    o changes to permit hi-res, cubed-sphere, configuration
533      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
534      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
535      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
536        of surface winds for the cube
537      (A verification experiment, based on global_ocean.cs32x15, but with
538       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
539       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
540       complete with example surface forcing files and matlab scripts to look
541       at the output and compare it with that of global_ocean.cs32x15.)
542    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
543       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
544       to conform to the common rule.
545    o check-in the first version of the coupler + interfaces for multi-components
546       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
547       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
548       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
549       - ocean and atmos. share the same horizontal grid (no interpolation).
550       - exchanges between component and coupler is done in forward_step
551    o new verification experiment, cpl_aim+ocn:
552       coupled ocean - AIM atmosphere on cs32 grid.
553    
554    checkpoint52d_pre
555    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
556    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
557    
558    checkpoint52c_post
559    o Fixing OPTIONS files for use of exf:
560      - ALLOW_ECCO not needed
561      - ECCO_CPPOPTIONS.h should not be included from
562        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
563        as has been the case in the past
564      - All cal/exf related options are currently set in
565        single header file. Should remain so until we
566        agree on a consistent new policy.
567    o Removed all CPP options for cal package.
568      cal has no more CPP options.
569    o modified STOREs in GAD_ADVECTION
570    o corrected key comp. for passkey
571    
572    checkpoint52b_post
573    o new version: "thsice" of thermodynamic sea-ice pkg:
574     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
575     - modify fluxes but do not change theta directly;
576     - light cleaning of bulk_force pkg (still needed with thsice).
577     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
578       + output_thsice.txt to test thsice & bulk_force pkgs.
579    o put back grid & coriolis monitor output.
580    checkpoint52b_pre
581    
582    o call "do_the_model_io" at the beginning (=> dump initial state)
583    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
584    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
585      (need info on NUMBER_OF_PTRACERS)
586    o missing PTRACERS headers in some routines
587    o default tamc.h in pkg/autodiff supposed to crash
588      to ensure proper customization
589    
590    checkpoint52a_post
591    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
592      - moved surfaceTendencyTice from pkg/seaice to main code
593      - subroutine FREEZE_SURFACE now limits only surface temperature
594        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
595        => new output.txt for global_ocean.cs32x15 & global_with_exf
596      - keep the old version of FREEZE for backward compatibility;
597        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
598      - corresponding modifs for TAF directives
599    o added surface flux output variables to TIMEAVE_STATVARS

606    o some bug fixes for #undef REAL4_IS_SLOW
607    
608    checkpoint52 = ecco_c52_e35
609    o after testing adjoints of checkpoint51u_post
610    
611    checkpoint51u_post
612    o this is the post-merge tag of the ecco-branch
613      (needs another clean checkout and re-testing)
614    o various natl_box_adjoint configs and results
615      but no input fields
616    o obcs adjoint not yet merged!
617    o adding ECCO global 1x1 and 2x2 degree configs
618    o updated/extended some store directives for seaice
619    o pkg/ecco now containes ecco-specific part of cost function
620    o top level routines the_main_loop, forward_step
621      supersede those in model/src/
622      previous input data.cost now in data.ecco
623      (new namelist ecco_cost_nml)
624    o in ctrl/ cleaned some cross-dependencies and updated CPP options
625    
626    checkpoint51t_post
627    o this is the pre-merge tag of the ecco-branch
628    
629    checkpoint51s_post
630    o cleanup: removed various obsolete #define-s
631    o pkg/grdchk
632      - renamed 'ph-grd 3' to 'grad-res'
633      - merged from ecco-branch
634        (remaining bug fixes for obcs gradient checks)
635      - additional high-precision output for testreport
636        (grep for 'precision_grdchk_result')
637    
638    checkpoint51r_post
639    o cleaned up or removed CPP_OPTIONS.h files
640    o updated results for some of the tests to reflect the new
641      optfiles (-ieee: -O0 instead of -O3)
642    
643    checkpoint51q_post
644    o cd_code:
645      - moved cd_scheme.F -> cd_code_scheme.F
646      - separate read_checkpoint from cd_code_ini_vars.F
647      - separated cd_code part from write_checkpoint
648      - updated AD_SOURCE, generated .flow
649      - added CD_CODE_VARS.h to the_main_loop
650      - Moving cd_code specific store dir.s to pkg/cd_code
651    o ctrl package totally restructured
652      - pack/unpack now optional and decoupled from
653        xx_/adxx_ I/O
654      - ctrl_pack/unpack cleaned
655        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
656      - confined inclusion of AD_CONFIG.h to where necessary.
657    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
658    
659    checkpoint51p_post
660    o create initial cd_code package
661      - WARNING: the initialization of fields within packages
662        is broken because INI_FIELDS (where READ_CHECKPOINT is
663        called) is called *before* PACKAGES_INIT_VARIABLES.
664        This seems to be backwards since
665        1) its important to initially zero the entire field including
666           the "halo" region
667        2) zeroing needs to be done *before* reading pickup info
668           and the pickup call might or might not happen in any
669           particular run
670      - this needs an overhaul for R2
671    o cleanup verification/*/code/GMREDI_OPTIONS.h
672    o cleanup testreport
673    
674    checkpoint51o_post
675    o bringing AD-related verif's up to date with genmake2

684      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
685        change rho -> rho-rhoConst
686      - replace call find_rho to find_rhonum
687    o initialisation of rFlx extended to full array (required by TAF)
688      and shifted to thermodynamics
689    o removed PTRACERS.h in ptracers routine

708        (this means new output.txt for global_ocean.90x40x15,
709         global_ocean.cs32x15, and global_with_exf)
710    o added surface flux output variables to TIMEAVE_STATVARS
711    
712    checkpoint51n_pre
713    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

735    o enable to apply restoring on S & T only in a latitude band.
736    o update output (external_forcing_surf modif. change truncation errors)
737       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
738    
739    checkpoint51k_post
740    o change default to: useNHMTerms=.FALSE.
741     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):

765           - pkg_ad_check_lev?_dir.h
766    
767    checkpoint51i_post
768    o merge of the branch-genmake2

800        "USE_EXF_INTERPOLATION" to pkg/exf.
801      - This is a temporary Cartesian-grid hack until
802        the super-duper ESMF coupler becomes available.
803      - See verification/global_with_exf/README for usage example.
804      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
805        flags and modified pkg/seaice accordingly.
806    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
807        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
808        non-local transport term.
809    
810    checkpoint51e_post
811    o pkg/mom_vecinv:
812      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)
813      - add time-ave diagnostic of vorticity advection.
814    o add diagnostic (instantaneous) of Shapiro Filter effect for T,S & UV.
815    o atmospheric geopotential: - include water vapor effect;
816                                - use p^kappa in p* scaling.
817    o land pkg: read initial state from files.
818    o AIM : add stratospheric drag in the upper level
819    
820    checkpoint51d_post
821    o change function ILNBLNK (=> last non-blank char.) to return zero
822      (instead of the string length) when the string. char is empty
823    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
824    o modif's to restore TAMC compatibility
825      - avoid "_d" constructs in PARAMETER declarations
826      - avoid interrupting lines by comment lines
827    o Use cluster local disks for purely local I/O
828      vs. globally visible disks needed for ctrl stuff
829      (merged from ecco-branch)
830      - new active_file_loc... and mdsio_..._loc routines
831      - affected packages: autodiff, ctrl, grdchk, mdsio
832    
833    checkpoint51c_post
834    o introducing integer flag debugLevel
835      - debLevZero: suppress all output
836      - debLevA: standard
837      - debLevB: equivalent to current debugMode=.TRUE.
838    o introducing pathname variable mdsioLocalDir for mdsio
839      that can be specified at runtime
840      (relevant for cluster I/O to local disk)
841    `
842    >>>checkpoint51b_post
843    adjoint of ptracers
844    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
845    o extended state in checkpoint_lev?, etc.
846    o alternative ctrl/cost with tr1 or ptracer
847    o new comlev1_bibj_ptracers
848    o new ptracers.flow
849    o made ptracers_forcing same as external_forcing_s
850    o added verification for adjoint with ptracers
851      - adm. grdchk fail so far
852      - tlm. grdchk OK
853      - checked tapelev/comlev recomputations: OK
854    <<<checkpoint51b_pre
855    
856    checkpoint51a_post
857    o added code for biogeochemistry package
858      - new pkgs: dic, gchem
859      - new subroutine in ptracers
860    o modify code for biogeo packages
861      - in model/src and pkg/ptracers
862    
863    checkpoint51
864    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
865      - autodiff, ctrl, exf, grdchk, seaice
866      kept separate packages
867      - cost, ecco, obcs
868    o updating verification/internal_wave, verification/lab_sea
869      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
870    
871    checkpoint50i_post
872    o Preparing next differentiable checkpoint and sync
873      of MAIN vs. ecco-branch
874      - 1st step: this one is differentiable
875      - 2nd step: next(! not this) checkpoint will have updated packages
876                  from ecco-branch)
877    
878    checkpoint50h_post
879    o new package "land": provide surface BC for AIM.
880    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
881  o AIM: use true log-P extrapolation for near surface temp (= as in  o AIM: use true log-P extrapolation for near surface temp (= as in
882      F.Molteni paper) ; update aim.5l_cs output.      F.Molteni paper) ; update aim.5l_cs output.
883    o New variable in PARM03 for more flexible pickups
884    o somewhat cleaned package initialisation sequence for
885      ctrl/ cost/ ecco/ in packages_... routines
886    
887  checkpoint50g_post  checkpoint50g_post
888  o merged with release1_p17 (pkg/seaice and verification/lab_sea)  o merged with release1_p17 (pkg/seaice and verification/lab_sea)
