4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o fix multi-category seaice:
8     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
9       SEAICE_MULTICATEGORY
10     - fix short wave heat flux
11    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
12       and allow to use EVP solver. Change forward lab_sea: test both EVP
13       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
14    o Initial check-in of lab_sea adjoint
15      (very similar to natl_box_adjoint/code_seaice)
16      * used C-grid and EVP solver
17      * used KPP, GM/Redi
18      * uses inAdExact=.TRUE.
19      * gradient checks fail for both ADM and TLM
20        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
21        f.d. gradients actually seem more problematic than ADM, TLM gradients;
22        issue is related to forward mismatch between g77 an ifort
23    o pkg/seaice: overhaul of thermodynamics
24     - growth.F and groatb.F are replaced by new routine seaice_growth.F
25     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
26     - move a few global fields out of SEAICE.h into seaice_growth.F and
27       make them 2D (FICE/QNETO/ ...)
28     - remove FO (it is the same as QNETO)
29     - introduce a few local fields to avoid modifying external fields such
30       as atemp, etc.
31    
32    checkpoint58s_post
33    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
34      changed exf_set_gen.F so that
35        genperiod=0 means input file is one time-constant field and
36        genperiod=-12 means input file contains 12 monthly means
37    o CG2D: use pre-computed solver main-diagonal (stored in common block);
38      this affects truncation error ; generate new output file for exp. which
39      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
40        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
41        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
42        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
43        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
44        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
45    o start implementation of deep-atmosphere and anelastic formulation
46    o verification: remove 2nd copy of input files and use script "prepare_run"
47      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
48    o mom_common/vecinv/fluxform: fix a few initialisation isssues
49    o profiles: fix for multithreaded case
50    
51    o diagnostics: rename few diags:
52      s/'PRESSURE'/'RCENTER '/g
53      s/'TICE    '/'oceFreez'/g
54      s/'TAUX    '/'oceTAUX '/g
55      s/'TAUY    '/'oceTAUY '/g
56      s/'SWFLUX  '/'oceQsw  '/g
57      s/DIFx/DFxE/g
58      s/DIFy/DFyE/g
59      and add few ocean-forcing diagnostics:
60      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
61    o modifications to pkg/seaice/growth.F and budget.F, which change results of
62      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
63      as actual snow thickness.  It now refers everywhere to effective snow
64      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
65    
66    checkpoint58r_post
67    o modifications to pkg/seaice/growth.F, which change results of
68      lab_sea experiment: fixes pertain to melting snow over open water, to
69      masking EVAP under sea ice, and to using the correct AREA variable for
70      computations of EVAP, PRECIP, HSNOW, and GHEFF
71    o add ability to read bathy, salt, and theta using MNC (off by def)
72    o add flooding algorithm and advection of HSNOW for pkg/seaice;
73      both are turned off by default and do no change any results
74    o seaice advection with pkg/thsice: a step toward the use of non-linear
75      advection scheme, but #ifdef or commented out for now (requires more EXCH).
76    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
77      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
78      in natl_box (affects results @ truncation level: update output.txt)
79    o multi-threading and IO:
80      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
81      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
82        (needed to work with SingleCpuIO): tested in all verif. exp.
83    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
84      affects the results (but none of the verification test uses this scheme).
85    o Adding some pkg/diagnostics capability to pkg/seaice
86      (will certainly be subject to changes)
87    o ctrl: adding new control variables:
88      lwflux, lwdown, evap, snowprecip, apressure, runoff
89    
90    checkpoint58q_post
91    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
92      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
93      high_res_cube configuration by 4% on Columbia.
94    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
95      add (in global_with_exf/code) a version of EXF_INTERP_READ without
96      dynamical allocation (seems to work in multi-threaded).
97    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
98      single CPU io) so that TAF does not have to see EESUPPORT.h
99    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
100    
101    checkpoint58p_post
102    o obcs: stop if obcs is used with useCDscheme = .true.
103    o shelfice:
104     - fix a sign error so that no slip at shelfice interface works
105     - remove stop for combination non-hydrostatic code and shelfice. That does
106       not mean, that the results are correct, but at least they are numerically
107       stable
108    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
109    o added adjoint exch routined for all exch*3d* routines
110      and updated flow directives
111    
112    checkpoint58o_post
113    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
114      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
115    o change controling S/R for writing pickup file (new S/R do_write_pickup)
116      and clean-up reading/writing of pickup files.
117    o fix local version of read/write pickup (NH part) in rotating_tank/code
118    o simplify EXCH interface:
119     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
120     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
121    o added the regrid package
122    o shelfice:
123     - add a simple boundary layer scheme to reduce noise
124     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
125    
126    checkpoint58n_post
127    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
128       local variable (not in common block).
129    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
130      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
131      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
132        to work with SingleCpuIO.
133    o add "_d 0" to real constant of pkg/cfc subroutines ;
134       update exp. cfc_exemple & tutorial_cfc_offline output files.
135    o multi-threading and IO:
136      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
137        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
138      - barrier before and after reading.
139      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
140      - avoid using MDS_WRITELOCAL for LAND pkg output.
141      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
142        common-block variables ; Allows multi-threading with master-thread IO.
143    o change default MAX_NO_THREADS from 32 to 4 ;
144      and stop cleanly when MAX_NO_THREADS is too small.
145    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
146    
147    checkpoint58m_post
148    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
149       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
150    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
151       keep global_ocean.90x40x15 (for AD testing) with former secondary test
152       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
153    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
154        add MITgcm_tutorials (= code + all the tutorials)
155    o ecco, option to compute cost for total ssh (mean+anom)
156    o consistent with addition of ptracer and ssh in pkg/profiles
157    o profiles: adding ptracer and ssh
158    o testreport: change multi-test output-file name
159      (from output.txt.{name} to output.{name}.txt)
160    o profiles: now ok for mutli-tiles case
161    o seaice: add 4 parameters for different advection schemes for area,
162      (effective) seaice thickness, enthalphy, and snow height. Their default
163      is the standard parameter SEAICEadvScheme
164    o calc_gw:
165     - add cosFacU in zonal viscous flux (harmonic.visc.).
166     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
167       of tutorial_plume_on_slope.
168    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
169    o calc_gw: true flux-form, account for horizontal grid spacing.
170      update rotating_tank results, but not plume_on_slope (affected at
171      truncation level, 11 digits).
172    
173    checkpoint58l_post
174    o calc_gw:
175     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
176     - remove side-drag for now (need to fix it); update plume_on_slope results.
177     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
178    o commit code to make SST/SSS weights spatially variable
179      (based on either variable in-situ or variable initial T/S weights)
180    o pkg/ecco:
181      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
182        now based on horizontally varying weights wthetaLev, wsaltLev
183      * cost_averagesflags now returns year indices in addition to day, month
184      * sflux balance is performed on annual basis
185        (sflxumm, sfluxmm2, bal_sfluxmm)
186      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
187        including separate counting and multipliers
188    o pkg/rbcs
189      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
190    
191    checkpoint58k_post
192    o testreport:
193     - always build in dir. "build" (if not there, mkdir build instead of building
194       & running in input)
195     - run in dir run (if it exists), in build otherwise.
196     - call prepare_run (if input/prepare_run exists)
197     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
198    o pkg/exf modifications to interpolation and rotation routines for more
199       reasonable treatment of North Pole singularity: for tracers North Pole
200       value is set to northernmost zonal-mean value, for zonal velocity it is
201       set to zero, and for meridional velocity it is set to northernmost value.
202    o pkg/exf/exf_check_range.F
203     - add tile index to diagnostics and move stop statement to the very
204       end of the routine.
205    o pkg/diagnostics: (diagnostics_main_init.F)
206      define title of isomorphic variables according to the current config.
207    o pkg/thsice with pkg/seaice dynamics:
208    - fix domain of computation (interior only, required for exf) and do exchanges
209    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
210    o towards a standard way of dealing with multi-threading in MONITOR
211      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
212    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
213       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
214    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
215    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
216    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
217       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
218    o tracer advection:
219     - clean-up and simplify calc_common_factors.F
220     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
221       advection subroutine (but still not used within DST advection S/R)
222    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
223    
224    checkpoint58j_post
225    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
226      from file (collects calls previously in FORWARD_STEP)
227    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
228    o adjoint store dir. adjusted accordingly
229    o genmake2
230      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
231    
232    checkpoint58i_post
233    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
234      on wind stress (SEAICEstressFactor defaults to 1.)
235    o Total number of Timers is finite (<=40): comment out 2 non-essential one
236      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
237    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
238      on CS-grid: no longer loosing mass.
239    o exf & curvilinear-grid: no longer modify longitude xC & xG.
240    o pkg/ggl90: fix sloppy output and fix a bug
241    o pkg/seaice: added SEAICEuseEVPpickup parameter
242      - Set to false in order to start EVP solver with
243        non-EVP pickup files when using SEAICEuseEVP
244      - fix sign error in diffusion in seaice_calc_rhs
245    
246    checkpoint58h_post
247    * Modifications for bottom topography control
248      o replace hFacC by _hFacC at various places
249      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
250      o add non-self-adjoint cg2d_nsa
251      o update autodiff support routines
252      o re-initialise hfac after ctrl_depth_ini
253      o works for 5x5 box, doesnt work for global_ocean.90x40x15
254    * Adding verification for 5x5 box (4-layer) bottom topography control
255    
256    checkpoint58g_post
257    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
258       used for mean seasonal cycle, mean diurnal cycle); add an example
259       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
260    o pkg/ggl90:
261      - add parameter (minimum surface kinetic energy)
262      - fix bug (avoiding division by zero)
263    o couple pkg/thsice to pkg/seaice:
264      - modify advection in seaice to accomodate new scalar fields to be advected
265      - only muliDimAdection scheme work with seaice/thsice
266      - mapping of thsice-variables to seaice-variables, back and forth
267      - does not break the verification experiments, but does not give the
268        desired results either
269    o pkg/seaice
270      - make (default) second order advection a bit less confusing?
271    
272    checkpoint58f_post
273    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
274      to pkg/seaice):
275      - new routines thsice_map_exf and thsice_get_exf provide the interface
276      - add an additional formal parameter to thsice_solve4temp
277    o pkg/exf:
278      - add new fields wspeed, snowprecip (to be able to couple to thsice)
279      - correct Stefan-Boltzmann constant
280      - new parameter for longwave surface emittance
281      - separate some stuff from exf_bulkformulae into new routines  
282        exf_radiation, exf_wind
283      - add new parameters and constants: longwave emissivity for ocean, ice
284        and snow, evaporation parameters over ice
285      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
286        either wind from stress or stress from wind
287    o pkg/thSIce:
288    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
289    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
290       and THSICE_CALC_THICKN
291    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
292    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
293      to make debugging easier.
294    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
295    o pkg/bulk_force:
296      - clean-up comments and parameters ;
297      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
298    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
299      generate new output for test-experiment: aim.5l_cs.thSI
300    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
301      testreport accordingly
302    
303    checkpoint58e_post
304    o SEAICE_CGRID adjoint done
305    o R_STAR adjoint implemented.
306      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
307      * need to sort out init. of h0facc, etc.
308    o Make pkg/profile fully independent of ecco,cost, etc. stuff
309      to be able to use it in pure forward.
310    
311    checkpoint58d_post
312    o upgrade simple test-experiment to tutorial example:
313     step.1: duplicate the experiment and (step.2) will remove the old copy.
314      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
315      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
316      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
317      tutorial_global_oce_biogeo    <- copy of dic_example
318      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
319      tutorial_plume_on_slope       <- copy of plume_on_slope
320      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
321      tutorial_global_oce_optim     <- empty for now (David ?)
322      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
323     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
324    o correct a sign problem in cost_scat.F
325    o obcs and ptracers: fix boundary conditions for advections schemes
326      with larger stencil
327    o thsice adjoint: start
328    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
329      completeness
330    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
331      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
332    o ptracers adjoint:
333      * avoid extensive recomputatations
334      * fix missing re-init. of gptr (missed by TAF)
335    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
336      me to turn off the excessive output to STDOUT that this package produces
337    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
338      and add those terms in Vector-Invariant formulation.
339    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
340      if the control period (xx_hfluxperiod etc) is 0
341    o in profiles pkg, clean routines and fix details
342    o in ecco pkg, reading ssh data:
343      fix problem in case the model does not start at iter0=0
344    o fix mnc-pickup/restart for ptracers
345    o new package prifiles:
346      code to compute profile-based cost by Gael Forget
347      (modifs in ecco, ctrl, autodiff)
348    o Benign bug fix in initialization (spotted by M. Mazloff) of
349      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
350    
351    checkpoint58c_post
352    o adjoint: finish NLFS adjoint and provide reference output in
353      verification/global_ocean.90x40x15/results_ad_nlfs
354    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
355      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
356      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
357      with SEAICE_CGRID defined.
358    o move calendarDumps from "data" to "data.cal" and clean-up the code
