5      ==============================      ==============================
6    
7    o change calculation of Visbeck K:
8      - no longer depend on tapering scheme; instead, compute slope (limited
9        by GM_maxSlope). this is equivalent to what was comuted before with
10        clipping or linear tappering.
11      - fix vertical averaging (wrong by 1 level)
12      - leave the old version (but will not be maintained) within
13        #ifdef OLD_VISBECK_CALC / #endif
14    o change error catch in calc_r_star to improve vectorization
15    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
16      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
17    
18    checkpoint59b
19    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
20      - export/import (between ocean & coupler) fields needed for ocean DIC.
21    o pkg/seaice:
22      - get rid of three more exchanges seaice_calc_viscosities (required
23        different loop boundaries in seaice_lsr and seaice_ocean_stress)
24      - bug fix in seaice_ocean_stress (update of lab_sea required)
25      - reduce loop boundaries to necessary minimum also in seaice_evp
26      - go back to the old way of computing deltaC/Z as the adjoint likes that
27        better
28    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
29      passive tracer to an Age Tracer) + update output.txt
30    o pkg/exf:
31      - implement A-grid / C-grid selection for wind-stress input files.
32      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
33      for now, in exf_bulk_largeyeager04.F only :
34      - change implementation for case where windspeed + 2. components wind-stress
35        are read-in. AND use rhoConstFresh to convert evap.
36    o pkg/seaice:
37      - use correct EXCH_UV for wind-forcing (on A-grid).
38      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
39        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
40    o pkg/exf:
41      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
42      EXF_INTERPOLATION:
43      - merge global_with_exf/code version of exf_interp_read.F
44        to the main code ;
45      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
46        reading the file ; Important: This options needs to be defined to recover
47        previous code.
48        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
49      - no longer loose real*8 precision along the way when using exf_iprec=64.
50    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
51      - change discretisation of evp-solver in order to avoid another exchange
52        (changes lab_sea) and clean up a little
53      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
54        help the adjoint (this also changes the results slightly)
55      - add a few "_d 0" where they had been missing in seaice_evp.F
56      - cleaning up: remove unused seaice_calc_rhs.F
57    o pkg/exf: some cleaning-up:
58      - change various "constants" into runtime parameters
59      - cleaned-up Large&Yeager04 routine which should eventually
60        replace exf_bulkformulae.F (changed names of S/R and CPP)
61        and merged various ALLOW_ATM_WIND options
62     only used with thsice pkg (in thsice_get_exf.F):
63      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
64        which are used when useStabilityFct_overIce=TRUE (= the default)
65      - change default values of ice & snow emissivity and scale downward LW
66        by ice & snow emissivity.
67    o pkg/thsice:
68     fix few little problems, in thsice_calc_thickn.F:
69      - growth vertically (and not laterally) if iceFrac == iceMaskMax
70      - melt laterally only if hIce < hThinIce (as the comments say)
71      and in thsice_extend.F:
72      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
73      - start to form ice as soon as the minimum ice-volume is reachable.
74     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
75      and cpl_aim+ocn
76    o pkg/kpp
77     - move computation of surface related input fields to KPP into a new
78       subroutine kpp_forcing_surf.F
79     - remove wrong (within bi,bj loops) EXCH calls.
80     - little cleaning (add argument myThid in last position, cvs header ...)
81     - for now, fix conservation problem by exchanging KPPviscAz (may not
82       be the best fix)
83    o pkg/seaice
84     - check for inconsistent evp parameter/cpp-flag combination
85     - remove leftover errIO flat for obsolete name list error handling
86    o OpenAD
87     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
88    
89    checkpoint59a
90    o pkg/seaice: some parameter clarifications and a little bit of clean up
91    o pkg/thsice: rename run-time parameters:
92       himin       -> hIceMin
93       himin0      -> hThinIce
94       hihig       -> hThickIce
95       i0          -> i0swFrac
96       transCoef   -> bMeltCoef
97       frac_energy -> fracMelting
98      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
99       with default values (for now) that do not change the results.
100      remove old version of thsice vars advection in pkg/seaice.
101    o in FFIELDS.h:
102      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
103      - make pLoad & sIceLoad always available (but still only used if
104         ATMOSPHERIC_LOADING is #define).
105    o pkg/kpp: replaced _KPP_RL with _RL
106    o bug fixes for vertical diffusivity computations when both KPP and
107        3D diffusivity arrays are used.
108    o pkg/seaice: fix bug in evp solver, while doing that
109      - change (improve?) discretization of stress computations for both
110        cgrid-lsr and evp solver
111      - add a new routine to compute strain rates
112      - the above changes lab_sea results
113      - add no slip conditions for evp solver (off by default), lsr-version
114        may follow
115      - fix exchange for shear at Z-points (does not change lab_sea)
116      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
117        (to force the user to pick a time step since there is not "safe" way
118        of choosing it)
119      - add principal stress diagnostics
120      - rearrange fields for evp a little to avoid having to call a: too many
121        exchanges and b: exchanges for stress trensor components which we do
122        not have.
123      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
124        of evp, complete rewrite for lsr case (latter is does not yet work
125        in all cases)
126    o pkg/kpp: add code to have mixing in shelf ice caverns
127      - add myThid to all kpp routines (long overdue)
128    
129    checkpoint59
130    o pkg/exf:
131      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
132        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
133      - move exf header files from lower_case.h to UPPER_CASE.h ;
134        add missing cvs Header & Name
135      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
136      - add namelist param. selectStressGridPosition, exf_monFreq
137      - retire many _CLIM routines, and remove data.exf_clim
138        + params moved to data.exf
139        + climsst, climsss now handled by exf_set_gen, i.e.
140          climss?period=0 refers to constant field,
141          climss?period=-12 to monthly forcing
142      - split up namelists in data.exf
143    o pkg/seaice:
144      - remove seaice_exch and seaice_exch_uv
145      - remove superfluous exchange of theta
146      - add myThid to seaice_budget_ocean/ice
147      - add new interface for atmospheric wind forcing (C-grid only)
148        + new routine
149        + two new field (taux, tauy for stress over ice)
150        + removed one global field (DAIRN) for C-grid case only
151    o pkg/thsise
152      - 2nd set of modifs for thsice adjoint in conjunction with exf
153    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
154    
155    checkpoint58y_post
156    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
157      vertical diffusivity, similar to that in MOM4; turned on using
158      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
159      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
160    o Added capability for 3D specification of background vertical diffusion
161      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
162      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
163      "data" file that contains the 3D vertical diffusivity coefficients.
164    o ice dynamics (pkg/seaice) with thsice thermodynamics:
165      - add code within pkg thsice to advect & diffuse sea-ice fields
166      similar to (and will replace) what has been added in  seaice_advdiff.F,
167      but: - conserving Mass, Heat & Salt.
168           - better when using non-linear advection scheme (not yet fully tested)
169           - can also be used in atmospheric set-up (for now, only the diffusion).
170    
171    checkpoint58x_post
172    o IO option for global-file compact format:
173      - add options when generating topology (utils/exch2/matlab-topology-generator)
174      - add I/O capability (pkg/mdsio).
175      - adapt utils/matlab/rdmds.m to read this format.
176      for now long-line format not yet supported by pkg/mdsio (& exch2).
177    o shelfice: add a few diagnostics
178    
179    checkpoint58w_post
180    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
181      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
182      (and replace horiVertRatio in NH code).
183      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
184                         and tutorial_plume_on_slope (sensitive to truncation)
185    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
186      directly to drive seaice model (C-grid only)
187    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
188     - reintroduce computation of wind from stress,
189     - compute tau (in exf_bulkformulae.F) from windstress averaged to
190       mass points to avoid tau = 0
191     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
192    o rdmnc.m: make it work with "global" files created with gluemnc
193    o rdmnc.m : some improvements in dealing with singleton dimension
194      (tested on all testreport mnc output files).
195    o genmake2: disable pkg/profiles if netcdf test fails.
196    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
197    o move call to cal_readparms up to make calendar parameters/variable available
198      to all packages
199    
200    checkpoint58v_post
201    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
202      useDynP_inEos_Zc tested.
203    o pkg/exf: changes to properly interpolate/mask/scale initial fields
204    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
205      and portions thereof.  See read_cs.txt for description and examples.
206    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
207      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
208      following the great-circle arc between those 2 points.
209    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
210      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
211    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
212     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
213     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
214     - still needs work (not working with some options ; efficiency to improve)
215       and serious testing.
216     - use this scheme for temperature & salinity in 2 advection test exp.:
217       advect_xy & advect_xz, respectively.
218    
219    checkpoint58u_post
220    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
221    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
222    o testreport: add option "-skipdir" to skip some test.
223    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
224      momentum calculation.
225    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
226    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
227      remove checkpoint.F and the_correction_step.F (no longer used);
228      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
229    o add option (linFSConserveTr) to correct for tracer source/sink due to
230      Linear Free surface
231    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
232    o pkg/thsice: fix reading mnc-pickups
233    
234    checkpoint58t_post
235    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
236    o pkg/mdsio:
237     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
238       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
239       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
240     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
241     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
242       either MDS_READ_FIELD or MDS_WRITE_FIELD )
243     - new S/R (to replace MDSWRITEMETA), which allows to write more
244       informations (variable names, time ...) to meta files.
245     - modify rdmds.m to give back the meta file content.
246    o pkg/diagnostics: change vertical interpolation to be safer, and more
247       flexible (define p-levels to interpolate to in data.diagnostics);
248      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
249       diagnostic pointer.
250  o pkg/seaice: more cleaning up of seaice_growth, added many comments  o pkg/seaice: more cleaning up of seaice_growth, added many comments
251  o pkg/exf: put runoff0 and runoff into the appropriate common block  o pkg/exf: put runoff0 and runoff1 into the appropriate common block
252  o fix multi-category seaice:  o fix multi-category seaice:
253   - change cpp flag SEAICE_MULTILEVEL to more meaningful name:   - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
