4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
8    o pkg/exf: some cleaning-up:
9      - change various "constants" into runtime parameters
10      - cleaned-up Large&Yeager04 routine which should eventually
11        replace exf_bulkformulae.F (changed names of S/R and CPP)
12        and merged various ALLOW_ATM_WIND options
13     only used with thsice pkg (in thsice_get_exf.F):
14      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
15        which are used when useStabilityFct_overIce=TRUE (= the default)
16      - change default values of ice & snow emissivity and scale downward LW
17        by ice & snow emissivity.
18    o pkg/thsice:
19     fix few little problems, in thsice_calc_thickn.F:
20      - growth vertically (and not laterally) if iceFrac == iceMaskMax
21      - melt laterally only if hIce < hThinIce (as the comments say)
22      and in thsice_extend.F:
23      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
24      - start to form ice as soon as the minimum ice-volume is reachable.
25     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
26      and cpl_aim+ocn
27    o pkg/kpp
28     - move computation of surface related input fields to KPP into a new
29       subroutine kpp_forcing_surf.F
30     - remove wrong (within bi,bj loops) EXCH calls.
31     - little cleaning (add argument myThid in last position, cvs header ...)
32     - for now, fix conservation problem by exchanging KPPviscAz (may not
33       be the best fix)
34    o pkg/seaice
35     - check for inconsistent evp parameter/cpp-flag combination
36     - remove leftover errIO flat for obsolete name list error handling
37    o OpenAD
38     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
39    
40    checkpoint59a
41    o pkg/seaice: some parameter clarifications and a little bit of clean up
42    o pkg/thsice: rename run-time parameters:
43       himin       -> hIceMin
44       himin0      -> hThinIce
45       hihig       -> hThickIce
46       i0          -> i0swFrac
47       transCoef   -> bMeltCoef
48       frac_energy -> fracMelting
49      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
50       with default values (for now) that do not change the results.
51      remove old version of thsice vars advection in pkg/seaice.
52    o in FFIELDS.h:
53      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
54      - make pLoad & sIceLoad always available (but still only used if
55         ATMOSPHERIC_LOADING is #define).
56    o pkg/kpp: replaced _KPP_RL with _RL
57    o bug fixes for vertical diffusivity computations when both KPP and
58        3D diffusivity arrays are used.
59    o pkg/seaice: fix bug in evp solver, while doing that
60      - change (improve?) discretization of stress computations for both
61        cgrid-lsr and evp solver
62      - add a new routine to compute strain rates
63      - the above changes lab_sea results
64      - add no slip conditions for evp solver (off by default), lsr-version
65        may follow
66      - fix exchange for shear at Z-points (does not change lab_sea)
67      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
68        (to force the user to pick a time step since there is not "safe" way
69        of choosing it)
70      - add principal stress diagnostics
71      - rearrange fields for evp a little to avoid having to call a: too many
72        exchanges and b: exchanges for stress trensor components which we do
73        not have.
74      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
75        of evp, complete rewrite for lsr case (latter is does not yet work
76        in all cases)
77    o pkg/kpp: add code to have mixing in shelf ice caverns
78      - add myThid to all kpp routines (long overdue)
79    
80    checkpoint59
81    o pkg/exf:
82      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
83        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
84      - move exf header files from lower_case.h to UPPER_CASE.h ;
85        add missing cvs Header & Name
86      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
87      - add namelist param. selectStressGridPosition, exf_monFreq
88      - retire many _CLIM routines, and remove data.exf_clim
89        + params moved to data.exf
90        + climsst, climsss now handled by exf_set_gen, i.e.
91          climss?period=0 refers to constant field,
92          climss?period=-12 to monthly forcing
93      - split up namelists in data.exf
94    o pkg/seaice:
95      - remove seaice_exch and seaice_exch_uv
96      - remove superfluous exchange of theta
97      - add myThid to seaice_budget_ocean/ice
98      - add new interface for atmospheric wind forcing (C-grid only)
99        + new routine
100        + two new field (taux, tauy for stress over ice)
101        + removed one global field (DAIRN) for C-grid case only
102    o pkg/thsise
103      - 2nd set of modifs for thsice adjoint in conjunction with exf
104    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
105    
106    checkpoint58y_post
107    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
108      vertical diffusivity, similar to that in MOM4; turned on using
109      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
110      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
111    o Added capability for 3D specification of background vertical diffusion
112      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
113      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
114      "data" file that contains the 3D vertical diffusivity coefficients.
115    o ice dynamics (pkg/seaice) with thsice thermodynamics:
116      - add code within pkg thsice to advect & diffuse sea-ice fields
117      similar to (and will replace) what has been added in  seaice_advdiff.F,
118      but: - conserving Mass, Heat & Salt.
119           - better when using non-linear advection scheme (not yet fully tested)
120           - can also be used in atmospheric set-up (for now, only the diffusion).
121    
122    checkpoint58x_post
123    o IO option for global-file compact format:
124      - add options when generating topology (utils/exch2/matlab-topology-generator)
125      - add I/O capability (pkg/mdsio).
126      - adapt utils/matlab/rdmds.m to read this format.
127      for now long-line format not yet supported by pkg/mdsio (& exch2).
128    o shelfice: add a few diagnostics
129    
130    checkpoint58w_post
131    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
132      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
133      (and replace horiVertRatio in NH code).
134      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
135                         and tutorial_plume_on_slope (sensitive to truncation)
136    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
137      directly to drive seaice model (C-grid only)
138    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
139     - reintroduce computation of wind from stress,
140     - compute tau (in exf_bulkformulae.F) from windstress averaged to
141       mass points to avoid tau = 0
142     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
143    o rdmnc.m: make it work with "global" files created with gluemnc
144    o rdmnc.m : some improvements in dealing with singleton dimension
145      (tested on all testreport mnc output files).
146    o genmake2: disable pkg/profiles if netcdf test fails.
147    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
148    o move call to cal_readparms up to make calendar parameters/variable available
149      to all packages
150    
151    checkpoint58v_post
152    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
153      useDynP_inEos_Zc tested.
154    o pkg/exf: changes to properly interpolate/mask/scale initial fields
155    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
156      and portions thereof.  See read_cs.txt for description and examples.
157    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
158      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
159      following the great-circle arc between those 2 points.
160    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
161      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
162    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
163     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
164     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
165     - still needs work (not working with some options ; efficiency to improve)
166       and serious testing.
167     - use this scheme for temperature & salinity in 2 advection test exp.:
168       advect_xy & advect_xz, respectively.
169    
170    checkpoint58u_post
171    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
172    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
173    o testreport: add option "-skipdir" to skip some test.
174    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
175      momentum calculation.
176    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
177    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
178      remove checkpoint.F and the_correction_step.F (no longer used);
179      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
180    o add option (linFSConserveTr) to correct for tracer source/sink due to
181      Linear Free surface
182    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
183    o pkg/thsice: fix reading mnc-pickups
184    
185    checkpoint58t_post
186    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
187    o pkg/mdsio:
188     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
189       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
190       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
191     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
192     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
193       either MDS_READ_FIELD or MDS_WRITE_FIELD )
194     - new S/R (to replace MDSWRITEMETA), which allows to write more
195       informations (variable names, time ...) to meta files.
196     - modify rdmds.m to give back the meta file content.
197    o pkg/diagnostics: change vertical interpolation to be safer, and more
198       flexible (define p-levels to interpolate to in data.diagnostics);
199      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
200       diagnostic pointer.
201    o pkg/seaice: more cleaning up of seaice_growth, added many comments
202    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
203    o fix multi-category seaice:
204     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
205       SEAICE_MULTICATEGORY
206     - fix short wave heat flux
207    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
208       and allow to use EVP solver. Change forward lab_sea: test both EVP
209       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
210    o Initial check-in of lab_sea adjoint
211      (very similar to natl_box_adjoint/code_seaice)
212      * used C-grid and EVP solver
213      * used KPP, GM/Redi
214      * uses inAdExact=.TRUE.
215      * gradient checks fail for both ADM and TLM
216        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
217        f.d. gradients actually seem more problematic than ADM, TLM gradients;
218        issue is related to forward mismatch between g77 an ifort
219    o pkg/seaice: overhaul of thermodynamics
220     - growth.F and groatb.F are replaced by new routine seaice_growth.F
221     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
222     - move a few global fields out of SEAICE.h into seaice_growth.F and
223       make them 2D (FICE/QNETO/ ...)
224     - remove FO (it is the same as QNETO)
225     - introduce a few local fields to avoid modifying external fields such
226       as atemp, etc.
227    
228    checkpoint58s_post
229    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
230      changed exf_set_gen.F so that
231        genperiod=0 means input file is one time-constant field and
232        genperiod=-12 means input file contains 12 monthly means
233    o CG2D: use pre-computed solver main-diagonal (stored in common block);
234      this affects truncation error ; generate new output file for exp. which
235      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
236        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
237        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
238        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
239        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
240        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
241    o start implementation of deep-atmosphere and anelastic formulation
242    o verification: remove 2nd copy of input files and use script "prepare_run"
243      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
244    o mom_common/vecinv/fluxform: fix a few initialisation isssues
245    o profiles: fix for multithreaded case
246    
247    o diagnostics: rename few diags:
248      s/'PRESSURE'/'RCENTER '/g
249      s/'TICE    '/'oceFreez'/g
250      s/'TAUX    '/'oceTAUX '/g
251      s/'TAUY    '/'oceTAUY '/g
252      s/'SWFLUX  '/'oceQsw  '/g
253      s/DIFx/DFxE/g
254      s/DIFy/DFyE/g
255      and add few ocean-forcing diagnostics:
256      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
257    o modifications to pkg/seaice/growth.F and budget.F, which change results of
258      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
259      as actual snow thickness.  It now refers everywhere to effective snow
260      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
261    
262    checkpoint58r_post
263    o modifications to pkg/seaice/growth.F, which change results of
264      lab_sea experiment: fixes pertain to melting snow over open water, to
265      masking EVAP under sea ice, and to using the correct AREA variable for
266      computations of EVAP, PRECIP, HSNOW, and GHEFF
267    o add ability to read bathy, salt, and theta using MNC (off by def)
268    o add flooding algorithm and advection of HSNOW for pkg/seaice;
269      both are turned off by default and do no change any results
270    o seaice advection with pkg/thsice: a step toward the use of non-linear
271      advection scheme, but #ifdef or commented out for now (requires more EXCH).
272    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
273      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
274      in natl_box (affects results @ truncation level: update output.txt)
275    o multi-threading and IO:
276      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
277      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
278        (needed to work with SingleCpuIO): tested in all verif. exp.
279    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
280      affects the results (but none of the verification test uses this scheme).
281    o Adding some pkg/diagnostics capability to pkg/seaice
282      (will certainly be subject to changes)
283    o ctrl: adding new control variables:
284      lwflux, lwdown, evap, snowprecip, apressure, runoff
285    
286    checkpoint58q_post
287    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
288      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
289      high_res_cube configuration by 4% on Columbia.
290    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
291      add (in global_with_exf/code) a version of EXF_INTERP_READ without
292      dynamical allocation (seems to work in multi-threaded).
293    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
294      single CPU io) so that TAF does not have to see EESUPPORT.h
295    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
296    
297    checkpoint58p_post
298    o obcs: stop if obcs is used with useCDscheme = .true.
299    o shelfice:
300     - fix a sign error so that no slip at shelfice interface works
301     - remove stop for combination non-hydrostatic code and shelfice. That does
302       not mean, that the results are correct, but at least they are numerically
303       stable
304    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
305    o added adjoint exch routined for all exch*3d* routines
306      and updated flow directives
307    
308    checkpoint58o_post
309    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
310      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
311    o change controling S/R for writing pickup file (new S/R do_write_pickup)
312      and clean-up reading/writing of pickup files.
313    o fix local version of read/write pickup (NH part) in rotating_tank/code
314    o simplify EXCH interface:
315     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
316     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
317    o added the regrid package
318    o shelfice:
319     - add a simple boundary layer scheme to reduce noise
320     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
321    
322    checkpoint58n_post
323    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
324       local variable (not in common block).
325    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
326      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
327      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
328        to work with SingleCpuIO.
329    o add "_d 0" to real constant of pkg/cfc subroutines ;
330       update exp. cfc_exemple & tutorial_cfc_offline output files.
331    o multi-threading and IO:
332      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
333        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
334      - barrier before and after reading.
335      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
336      - avoid using MDS_WRITELOCAL for LAND pkg output.
337      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
338        common-block variables ; Allows multi-threading with master-thread IO.
339    o change default MAX_NO_THREADS from 32 to 4 ;
340      and stop cleanly when MAX_NO_THREADS is too small.
341    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
342    
343    checkpoint58m_post
344    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
345       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
346    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
347       keep global_ocean.90x40x15 (for AD testing) with former secondary test
348       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
349    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
350        add MITgcm_tutorials (= code + all the tutorials)
351    o ecco, option to compute cost for total ssh (mean+anom)
352    o consistent with addition of ptracer and ssh in pkg/profiles
353  o profiles: adding ptracer and ssh  o profiles: adding ptracer and ssh
354  o testreport: change multi-test output-file name  o testreport: change multi-test output-file name
355    (from output.txt.{name} to output.{name}.txt)    (from output.txt.{name} to output.{name}.txt)
