4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    checkpoint58u_post
8    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
9    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
10    o testreport: add option "-skipdir" to skip some test.
11    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
12      momentum calculation.
13    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
14    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
15      remove checkpoint.F and the_correction_step.F (no longer used);
16      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
17    o add option (linFSConserveTr) to correct for tracer source/sink due to
18      Linear Free surface
19    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
20    o pkg/thsice: fix reading mnc-pickups
21    
22    checkpoint58t_post
23    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
24    o pkg/mdsio:
25     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
26       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
27       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
28     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
29     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
30       either MDS_READ_FIELD or MDS_WRITE_FIELD )
31     - new S/R (to replace MDSWRITEMETA), which allows to write more
32       informations (variable names, time ...) to meta files.
33     - modify rdmds.m to give back the meta file content.
34    o pkg/diagnostics: change vertical interpolation to be safer, and more
35       flexible (define p-levels to interpolate to in data.diagnostics);
36      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
37       diagnostic pointer.
38    o pkg/seaice: more cleaning up of seaice_growth, added many comments
39    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
40    o fix multi-category seaice:
41     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
42       SEAICE_MULTICATEGORY
43     - fix short wave heat flux
44    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
45       and allow to use EVP solver. Change forward lab_sea: test both EVP
46       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
47    o Initial check-in of lab_sea adjoint
48      (very similar to natl_box_adjoint/code_seaice)
49      * used C-grid and EVP solver
50      * used KPP, GM/Redi
51      * uses inAdExact=.TRUE.
52      * gradient checks fail for both ADM and TLM
53        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
54        f.d. gradients actually seem more problematic than ADM, TLM gradients;
55        issue is related to forward mismatch between g77 an ifort
56    o pkg/seaice: overhaul of thermodynamics
57     - growth.F and groatb.F are replaced by new routine seaice_growth.F
58     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
59     - move a few global fields out of SEAICE.h into seaice_growth.F and
60       make them 2D (FICE/QNETO/ ...)
61     - remove FO (it is the same as QNETO)
62     - introduce a few local fields to avoid modifying external fields such
63       as atemp, etc.
64    
65    checkpoint58s_post
66    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
67      changed exf_set_gen.F so that
68        genperiod=0 means input file is one time-constant field and
69        genperiod=-12 means input file contains 12 monthly means
70    o CG2D: use pre-computed solver main-diagonal (stored in common block);
71      this affects truncation error ; generate new output file for exp. which
72      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
73        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
74        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
75        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
76        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
77        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
78    o start implementation of deep-atmosphere and anelastic formulation
79    o verification: remove 2nd copy of input files and use script "prepare_run"
80      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
81    o mom_common/vecinv/fluxform: fix a few initialisation isssues
82    o profiles: fix for multithreaded case
83    
84    o diagnostics: rename few diags:
85      s/'PRESSURE'/'RCENTER '/g
86      s/'TICE    '/'oceFreez'/g
87      s/'TAUX    '/'oceTAUX '/g
88      s/'TAUY    '/'oceTAUY '/g
89      s/'SWFLUX  '/'oceQsw  '/g
90      s/DIFx/DFxE/g
91      s/DIFy/DFyE/g
92      and add few ocean-forcing diagnostics:
93      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
94    o modifications to pkg/seaice/growth.F and budget.F, which change results of
95      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
96      as actual snow thickness.  It now refers everywhere to effective snow
97      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
98    
99    checkpoint58r_post
100    o modifications to pkg/seaice/growth.F, which change results of
101      lab_sea experiment: fixes pertain to melting snow over open water, to
102      masking EVAP under sea ice, and to using the correct AREA variable for
103      computations of EVAP, PRECIP, HSNOW, and GHEFF
104    o add ability to read bathy, salt, and theta using MNC (off by def)
105    o add flooding algorithm and advection of HSNOW for pkg/seaice;
106      both are turned off by default and do no change any results
107    o seaice advection with pkg/thsice: a step toward the use of non-linear
108      advection scheme, but #ifdef or commented out for now (requires more EXCH).
109    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
110      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
111      in natl_box (affects results @ truncation level: update output.txt)
112    o multi-threading and IO:
113      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
114      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
115        (needed to work with SingleCpuIO): tested in all verif. exp.
116    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
117      affects the results (but none of the verification test uses this scheme).
118    o Adding some pkg/diagnostics capability to pkg/seaice
119      (will certainly be subject to changes)
120    o ctrl: adding new control variables:
121      lwflux, lwdown, evap, snowprecip, apressure, runoff
122    
123    checkpoint58q_post
124    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
125      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
126      high_res_cube configuration by 4% on Columbia.
127    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
128      add (in global_with_exf/code) a version of EXF_INTERP_READ without
129      dynamical allocation (seems to work in multi-threaded).
130    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
131      single CPU io) so that TAF does not have to see EESUPPORT.h
132    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
133    
134    checkpoint58p_post
135    o obcs: stop if obcs is used with useCDscheme = .true.
136    o shelfice:
137     - fix a sign error so that no slip at shelfice interface works
138     - remove stop for combination non-hydrostatic code and shelfice. That does
139       not mean, that the results are correct, but at least they are numerically
140       stable
141    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
142    o added adjoint exch routined for all exch*3d* routines
143      and updated flow directives
144    
145    checkpoint58o_post
146    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
147      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
148    o change controling S/R for writing pickup file (new S/R do_write_pickup)
149      and clean-up reading/writing of pickup files.
150    o fix local version of read/write pickup (NH part) in rotating_tank/code
151    o simplify EXCH interface:
152     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
153     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
154    o added the regrid package
155    o shelfice:
156     - add a simple boundary layer scheme to reduce noise
157     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
158    
159    checkpoint58n_post
160    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
161       local variable (not in common block).
162    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
163      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
164      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
165        to work with SingleCpuIO.
166    o add "_d 0" to real constant of pkg/cfc subroutines ;
167       update exp. cfc_exemple & tutorial_cfc_offline output files.
168    o multi-threading and IO:
169      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
170        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
171      - barrier before and after reading.
172      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
173      - avoid using MDS_WRITELOCAL for LAND pkg output.
174      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
175        common-block variables ; Allows multi-threading with master-thread IO.
176    o change default MAX_NO_THREADS from 32 to 4 ;
177      and stop cleanly when MAX_NO_THREADS is too small.
178    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
179    
180    checkpoint58m_post
181    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
182       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
183    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
184       keep global_ocean.90x40x15 (for AD testing) with former secondary test
185       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
186    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
187        add MITgcm_tutorials (= code + all the tutorials)
188    o ecco, option to compute cost for total ssh (mean+anom)
189    o consistent with addition of ptracer and ssh in pkg/profiles
190    o profiles: adding ptracer and ssh
191    o testreport: change multi-test output-file name
192      (from output.txt.{name} to output.{name}.txt)
193    o profiles: now ok for mutli-tiles case
194    o seaice: add 4 parameters for different advection schemes for area,
195      (effective) seaice thickness, enthalphy, and snow height. Their default
196      is the standard parameter SEAICEadvScheme
197    o calc_gw:
198     - add cosFacU in zonal viscous flux (harmonic.visc.).
199     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
200       of tutorial_plume_on_slope.
201    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
202    o calc_gw: true flux-form, account for horizontal grid spacing.
203      update rotating_tank results, but not plume_on_slope (affected at
204      truncation level, 11 digits).
205    
206    checkpoint58l_post
207    o calc_gw:
208     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
209     - remove side-drag for now (need to fix it); update plume_on_slope results.
210     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
211    o commit code to make SST/SSS weights spatially variable
212      (based on either variable in-situ or variable initial T/S weights)
213    o pkg/ecco:
214      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
215        now based on horizontally varying weights wthetaLev, wsaltLev
216      * cost_averagesflags now returns year indices in addition to day, month
217      * sflux balance is performed on annual basis
218        (sflxumm, sfluxmm2, bal_sfluxmm)
219      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
220        including separate counting and multipliers
221    o pkg/rbcs
222      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
223    
224    checkpoint58k_post
225    o testreport:
226     - always build in dir. "build" (if not there, mkdir build instead of building
227       & running in input)
228     - run in dir run (if it exists), in build otherwise.
229     - call prepare_run (if input/prepare_run exists)
230     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
231    o pkg/exf modifications to interpolation and rotation routines for more
232       reasonable treatment of North Pole singularity: for tracers North Pole
233       value is set to northernmost zonal-mean value, for zonal velocity it is
234       set to zero, and for meridional velocity it is set to northernmost value.
235    o pkg/exf/exf_check_range.F
236     - add tile index to diagnostics and move stop statement to the very
237       end of the routine.
238    o pkg/diagnostics: (diagnostics_main_init.F)
239      define title of isomorphic variables according to the current config.
240    o pkg/thsice with pkg/seaice dynamics:
241    - fix domain of computation (interior only, required for exf) and do exchanges
242    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
243    o towards a standard way of dealing with multi-threading in MONITOR
244      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
245    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
246       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
247    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
248    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
249    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
250       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
251    o tracer advection:
252     - clean-up and simplify calc_common_factors.F
253     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
254       advection subroutine (but still not used within DST advection S/R)
255    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
256    
257    checkpoint58j_post
258    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
259      from file (collects calls previously in FORWARD_STEP)
260    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
261    o adjoint store dir. adjusted accordingly
262    o genmake2
263      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
264    
265    checkpoint58i_post
266    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
267      on wind stress (SEAICEstressFactor defaults to 1.)
268    o Total number of Timers is finite (<=40): comment out 2 non-essential one
269      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
270    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
271      on CS-grid: no longer loosing mass.
272    o exf & curvilinear-grid: no longer modify longitude xC & xG.
273    o pkg/ggl90: fix sloppy output and fix a bug
274    o pkg/seaice: added SEAICEuseEVPpickup parameter
275      - Set to false in order to start EVP solver with
276        non-EVP pickup files when using SEAICEuseEVP
277      - fix sign error in diffusion in seaice_calc_rhs
278    
279    checkpoint58h_post
280    * Modifications for bottom topography control
281      o replace hFacC by _hFacC at various places
282      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
283      o add non-self-adjoint cg2d_nsa
284      o update autodiff support routines
285      o re-initialise hfac after ctrl_depth_ini
286      o works for 5x5 box, doesnt work for global_ocean.90x40x15
287    * Adding verification for 5x5 box (4-layer) bottom topography control
288    
289    checkpoint58g_post
290    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
291       used for mean seasonal cycle, mean diurnal cycle); add an example
292       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
293    o pkg/ggl90:
294      - add parameter (minimum surface kinetic energy)
295      - fix bug (avoiding division by zero)
296    o couple pkg/thsice to pkg/seaice:
297      - modify advection in seaice to accomodate new scalar fields to be advected
298      - only muliDimAdection scheme work with seaice/thsice
299      - mapping of thsice-variables to seaice-variables, back and forth
300      - does not break the verification experiments, but does not give the
301        desired results either
302    o pkg/seaice
303      - make (default) second order advection a bit less confusing?
304    
305    checkpoint58f_post
306    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
307      to pkg/seaice):
308      - new routines thsice_map_exf and thsice_get_exf provide the interface
309      - add an additional formal parameter to thsice_solve4temp
310    o pkg/exf:
311      - add new fields wspeed, snowprecip (to be able to couple to thsice)
312      - correct Stefan-Boltzmann constant
313      - new parameter for longwave surface emittance
314      - separate some stuff from exf_bulkformulae into new routines  
315        exf_radiation, exf_wind
316      - add new parameters and constants: longwave emissivity for ocean, ice
317        and snow, evaporation parameters over ice
318      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
319        either wind from stress or stress from wind
320    o pkg/thSIce:
321    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
322    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
323       and THSICE_CALC_THICKN
324    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
325    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
326      to make debugging easier.
327    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
328    o pkg/bulk_force:
329      - clean-up comments and parameters ;
330      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
331    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
332      generate new output for test-experiment: aim.5l_cs.thSI
333    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
334      testreport accordingly
335    
336    checkpoint58e_post
337    o SEAICE_CGRID adjoint done
338    o R_STAR adjoint implemented.
339      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
340      * need to sort out init. of h0facc, etc.
341    o Make pkg/profile fully independent of ecco,cost, etc. stuff
342      to be able to use it in pure forward.
343    
344    checkpoint58d_post
345    o upgrade simple test-experiment to tutorial example:
346     step.1: duplicate the experiment and (step.2) will remove the old copy.
347      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
348      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
349      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
350      tutorial_global_oce_biogeo    <- copy of dic_example
351      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
352      tutorial_plume_on_slope       <- copy of plume_on_slope
353      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
354      tutorial_global_oce_optim     <- empty for now (David ?)
355      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
356     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
357    o correct a sign problem in cost_scat.F
