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