4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o shelfice: add a simple boundary layer scheme to reduce noise
8    
9    checkpoint58n_post
10    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
11       local variable (not in common block).
12    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
13      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
14      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
15        to work with SingleCpuIO.
16    o add "_d 0" to real constant of pkg/cfc subroutines ;
17       update exp. cfc_exemple & tutorial_cfc_offline output files.
18    o multi-threading and IO:
19      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
20        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
21      - barrier before and after reading.
22      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
23      - avoid using MDS_WRITELOCAL for LAND pkg output.
24      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
25        common-block variables ; Allows multi-threading with master-thread IO.
26    o change default MAX_NO_THREADS from 32 to 4 ;
27      and stop cleanly when MAX_NO_THREADS is too small.
28    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
29    
30    checkpoint58m_post
31    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
32       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
33    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
34       keep global_ocean.90x40x15 (for AD testing) with former secondary test
35       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
36    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
37        add MITgcm_tutorials (= code + all the tutorials)
38    o ecco, option to compute cost for total ssh (mean+anom)
39    o consistent with addition of ptracer and ssh in pkg/profiles
40    o profiles: adding ptracer and ssh
41    o testreport: change multi-test output-file name
42      (from output.txt.{name} to output.{name}.txt)
43    o profiles: now ok for mutli-tiles case
44    o seaice: add 4 parameters for different advection schemes for area,
45      (effective) seaice thickness, enthalphy, and snow height. Their default
46      is the standard parameter SEAICEadvScheme
47    o calc_gw:
48     - add cosFacU in zonal viscous flux (harmonic.visc.).
49     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
50       of tutorial_plume_on_slope.
51    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
52    o calc_gw: true flux-form, account for horizontal grid spacing.
53      update rotating_tank results, but not plume_on_slope (affected at
54      truncation level, 11 digits).
55    
56    checkpoint58l_post
57    o calc_gw:
58     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
59     - remove side-drag for now (need to fix it); update plume_on_slope results.
60     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
61    o commit code to make SST/SSS weights spatially variable
62      (based on either variable in-situ or variable initial T/S weights)
63    o pkg/ecco:
64      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
65        now based on horizontally varying weights wthetaLev, wsaltLev
66      * cost_averagesflags now returns year indices in addition to day, month
67      * sflux balance is performed on annual basis
68        (sflxumm, sfluxmm2, bal_sfluxmm)
69      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
70        including separate counting and multipliers
71    o pkg/rbcs
72      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
73    
74    checkpoint58k_post
75    o testreport:
76     - always build in dir. "build" (if not there, mkdir build instead of building
77       & running in input)
78     - run in dir run (if it exists), in build otherwise.
79     - call prepare_run (if input/prepare_run exists)
80     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
81    o pkg/exf modifications to interpolation and rotation routines for more
82       reasonable treatment of North Pole singularity: for tracers North Pole
83       value is set to northernmost zonal-mean value, for zonal velocity it is
84       set to zero, and for meridional velocity it is set to northernmost value.
85    o pkg/exf/exf_check_range.F
86     - add tile index to diagnostics and move stop statement to the very
87       end of the routine.
88    o pkg/diagnostics: (diagnostics_main_init.F)
89      define title of isomorphic variables according to the current config.
90    o pkg/thsice with pkg/seaice dynamics:
91    - fix domain of computation (interior only, required for exf) and do exchanges
92    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
93    o towards a standard way of dealing with multi-threading in MONITOR
94      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
95    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
96       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
97    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
98    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
99    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
100       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
101    o tracer advection:
102     - clean-up and simplify calc_common_factors.F
103     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
104       advection subroutine (but still not used within DST advection S/R)
105    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
106    
107    checkpoint58j_post
108    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
109      from file (collects calls previously in FORWARD_STEP)
110    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
111    o adjoint store dir. adjusted accordingly
112    o genmake2
113      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
114    
115    checkpoint58i_post
116    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
117      on wind stress (SEAICEstressFactor defaults to 1.)
118    o Total number of Timers is finite (<=40): comment out 2 non-essential one
119      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
120    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
121      on CS-grid: no longer loosing mass.
122    o exf & curvilinear-grid: no longer modify longitude xC & xG.
123    o pkg/ggl90: fix sloppy output and fix a bug
124    o pkg/seaice: added SEAICEuseEVPpickup parameter
125      - Set to false in order to start EVP solver with
126        non-EVP pickup files when using SEAICEuseEVP
127      - fix sign error in diffusion in seaice_calc_rhs
128    
129    checkpoint58h_post
130    * Modifications for bottom topography control
131      o replace hFacC by _hFacC at various places
132      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
133      o add non-self-adjoint cg2d_nsa
134      o update autodiff support routines
135      o re-initialise hfac after ctrl_depth_ini
136      o works for 5x5 box, doesnt work for global_ocean.90x40x15
137    * Adding verification for 5x5 box (4-layer) bottom topography control
138    
139    checkpoint58g_post
140    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
141       used for mean seasonal cycle, mean diurnal cycle); add an example
142       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
143    o pkg/ggl90:
144      - add parameter (minimum surface kinetic energy)
145      - fix bug (avoiding division by zero)
146    o couple pkg/thsice to pkg/seaice:
147      - modify advection in seaice to accomodate new scalar fields to be advected
148      - only muliDimAdection scheme work with seaice/thsice
149      - mapping of thsice-variables to seaice-variables, back and forth
150      - does not break the verification experiments, but does not give the
151        desired results either
152    o pkg/seaice
153      - make (default) second order advection a bit less confusing?
154    
155    checkpoint58f_post
156    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
157      to pkg/seaice):
158      - new routines thsice_map_exf and thsice_get_exf provide the interface
159      - add an additional formal parameter to thsice_solve4temp
160    o pkg/exf:
161      - add new fields wspeed, snowprecip (to be able to couple to thsice)
162      - correct Stefan-Boltzmann constant
163      - new parameter for longwave surface emittance
164      - separate some stuff from exf_bulkformulae into new routines  
165        exf_radiation, exf_wind
166      - add new parameters and constants: longwave emissivity for ocean, ice
167        and snow, evaporation parameters over ice
168      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
169        either wind from stress or stress from wind
170    o pkg/thSIce:
171    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
172    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
173       and THSICE_CALC_THICKN
174    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
175    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
176      to make debugging easier.
177    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
178    o pkg/bulk_force:
179      - clean-up comments and parameters ;
180      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
181    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
182      generate new output for test-experiment: aim.5l_cs.thSI
183    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
184      testreport accordingly
185    
186    checkpoint58e_post
187    o SEAICE_CGRID adjoint done
188    o R_STAR adjoint implemented.
189      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
190      * need to sort out init. of h0facc, etc.
191    o Make pkg/profile fully independent of ecco,cost, etc. stuff
192      to be able to use it in pure forward.
193    
194    checkpoint58d_post
195    o upgrade simple test-experiment to tutorial example:
196     step.1: duplicate the experiment and (step.2) will remove the old copy.
197      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
198      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
199      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
200      tutorial_global_oce_biogeo    <- copy of dic_example
201      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
202      tutorial_plume_on_slope       <- copy of plume_on_slope
203      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
204      tutorial_global_oce_optim     <- empty for now (David ?)
205      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
206     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
207    o correct a sign problem in cost_scat.F
208    o obcs and ptracers: fix boundary conditions for advections schemes
209      with larger stencil
210    o thsice adjoint: start
211    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
212      completeness
213    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
214      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
215    o ptracers adjoint:
216      * avoid extensive recomputatations
217      * fix missing re-init. of gptr (missed by TAF)
218    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
219      me to turn off the excessive output to STDOUT that this package produces
220    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
221      and add those terms in Vector-Invariant formulation.
222    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
223      if the control period (xx_hfluxperiod etc) is 0
224    o in profiles pkg, clean routines and fix details
225    o in ecco pkg, reading ssh data:
226      fix problem in case the model does not start at iter0=0
227    o fix mnc-pickup/restart for ptracers
228    o new package prifiles:
229      code to compute profile-based cost by Gael Forget
230      (modifs in ecco, ctrl, autodiff)
231    o Benign bug fix in initialization (spotted by M. Mazloff) of
232      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
233    
234    checkpoint58c_post
235    o adjoint: finish NLFS adjoint and provide reference output in
236      verification/global_ocean.90x40x15/results_ad_nlfs
237    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
238      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
239      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
240      with SEAICE_CGRID defined.
241    o move calendarDumps from "data" to "data.cal" and clean-up the code
242      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
243    o add useEXF & useCAL flags (for now, set in hard-coded way)
244    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
245      (were missing in NH mode, and wrong in quasihydrostatic mode).
246      waiting for Chris updated version of calc_gw to add those CALLs.
247    o fix bug in quasihydrostatic S/R ;
248      add a test for this option: global_ocean.90x40x15.qshyd
249    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
250      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
251    o add on/off flag useOffLine for package OFFLINE
252    o seaice:
253      - modify advection so that it works also on the C-grid
254      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
255        problem in multi-tile runs with C-grid
256      - add flags for clipping ice velocities and/or masking solver forcing
257      - fix drag (ocean on ice) formulation and a bug that caused noise in the
258        C-grid solver
259      - added a few comments to seaice_diffusion.F
260      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
261        are now exclusive)
262      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
263        required re-ordering the code a little:
264       + make DAIRN global variable (defined in SEAICE)
265       + move computation of the viscosities eta and zeta into a new separate
266         routine (because I need to recompute them in seaice_ocean_stress.F)
267    
268    checkpoint58b_post
269    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
270      update output.txt of exp. aim.5l_cs.thSI
271    o various mnc cleanups and improvements:
272      + shrink lookup tables by factor of ~4
273      + better error reporting when running out of lookup space
274      + able to handle longer path/file names (up to 500 chars)
275    o adjoint:
276      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
277      - TBD: "hidden" mom_vecinv recomp. in dynamics
278    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
279     (allow to differentiate between forcing components using new integer flags:
280      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
281     and add new flag to put Dissipation tendency out of Adams-Bashforth.
282    o ecco
283      - enable trend removal from SSH anomaly obs.
284    o adjoint
285      - a fix for PmEpR when #undef EXACT_CONSERV
286      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
287      - try to fix "hidden" recomp. in forward_step for NLFS
288        (NLFS seems broken sometimes after I checked it in)
289    o seaice:
290     - add c-grid version of the dynamic solver:
291       + three new routines that are the c-grid substitute lsr, dynsolver
292         and ostres
293       + put a few fields that were local to dynsolver into global common
294         blocks, so that I can move the computation of stresses etc into
295         seaice_lsr (saves coding but may break the adjoint).
296     - replace more hardwired parameters by runtime parameters
297     - add ice masks that mask the rhs of the implicit solvers where there
298       is no ice (commented out in seaice_dynsolver, because i am not sure
299       if this works properly), eventually this should replace the clipping
300       of ice velocities in seaice_dynsolver to +/-40cm/s.
301    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
302      include it only where its needed
303    o move balancing of fluxes before the call of external_forcing_surf
304    o seaice:
305      - correct units of turning angles (now they are really in degrees)
306      - move computation of GWATX/Y out of main routine into dynsolver
307      - initialize GWATX/Y in seaice_init
308    o Apply mask on Fresh-Water flux (needed for SSH forcing).
309      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
310    o seaice: add runtime flags for turning angles (default to zero)
311    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
312      and trend from exf forcing and ctrl control adjustments
313    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
314      (since checkpoint57x_post)
315    o change the default rotation period to 86164.s = the Earth rotation
316    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
317      and based on a reference stratification. Tested within hs94.cs-32x32x5.
318    o seaice advection: add code for choosing between the default (2nd order
319      central differences) and multiDim advection schemes provided by
320      pkg/generic_advdiff
321    o seaice:
322      - removed all references to SEAICE_GRID.h fields from
323        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
324        (cubed-sphere configuration will change a little)
325      - grid computations in seaice_init are obsolete now.
326      - cleaned up code a little so that is easier to read (hopefully).
327      - added new (better?) discretizations of default advection and diffusion
328        (turn on with SEAICEuseFluxForm)
329      - replace 1 in 3d global fields by kSurface in growth.F
330      
331    checkpoint58a_post
332    o seaice:
333      - bug fix in advect.F
334    o shelfice:
335      - separate shelfice load anomaly from pload (breaks with time
336        dependent forcing), => introduce constant field shelficeLoadAnomaly.
337        Its default is 0., but it may be computed more cleverly from (unknown)
338        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
339        done offline. A good approximation of the pressure load anomaly is
340        necessary to avoid large initial adjustment processes underneath
341        deep-reaching shelfice.
342      - small fix in ISOMIP shelfice_thermodynamics
343      - add more sophisticated thermodynamics of Hellmer (1989), this is
344        now the default
345      - give a few constants more intuitive names
346    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
347      if bulk formulae are used in long integration (especially EmPmR). Turn
348      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
349      if balancePrintMean, the imbalance that is substracted is printed to
350      STDOUT.
351    o fix bug (typo) in obcs_apply_eta.F
352    o add a new package shelfice which enables us to model the circulation
353      underneath shelf-ice with draughts of hundreds of meters.
354     - works
355     - to do: + include improved thermodynamics
356              + check whether kSurfC (from model/inc/SURFACE.h) can be used
357                instead of new field kTopC
358              + can we use topoFile, Ro_surf and existing code in ini_depth.F
359                instead of new field R_shelfIce and new code in ini_depth.F
360                and ini_mask_etc.F?
361              + adjust vertical mixing schemes?
362    o seaice pkg:
363     - add a cpp-flag to include a simple formula for a salinity dependent
364       freezing point of sea water at the surface
365     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
366       meridional stresses are now different (and hopefully correct)
367    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
368       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
369       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
370    o pkg/diagnostics: add options and parameters for regional-statistics
371       diagnostics ; define regions by reading a region-mask from a file
372       (might add other options later)
373    o pkg/bulk_force:
374     - add option and parameters to use AIM surface-flux formulae.
375     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
376       others forcing fields (defined in PARM05, parameter file "data") are loaded
377       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
378     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
379     - use the right EXCH call for uwind,vwind (to work on CS-grid).
380     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
381       and parameters (note: calcWindStress replaces .NOT.readwindstress).
382     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).

385    o add "--embed-source" option to genmake2 which, when the supporting
386      tools can be compiled (as determined by genmake2) will turn on the
387      embed_files package which then embeds the entire MITgcm source code
388      (*.[fFhc] + Makefile) used for the build within the executable
389      - requested by CNH but off by default
390      - adds a paltry <9MB to the mitgcmuv executable in most cases
391      - only writes the output when useEMBEDSRC in eedata is true
392    o clean up 3-dim. relaxation codes:
393      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
394      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
395      * Thanks to Tom Haine for testing!

421      initial and boundary (forcing) controls (ic, bc)
422      * enable at compile-time via
423        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
424      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
425      * Absolute scale somewhat unclear so far
426      * no area weighting was included since no other cost term does so far
