4      ==============================      ==============================
5    
6    o removed gravitySign from PARM04
7    o switched to g77/ifc from pgf77 in aim experiments
8    
9    checkpoint46l_post
10    o made convective adjustment work with pressure coordinates:
11     - changed the direction of k-loop in convective_adjustment.F for the
12       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
13     - adjusted the reference pressure k-index in convective_adjustment.F
14     - adjusted the convection condition in convect.F (in analogy to
15       calc_ivdc.F)
16     - convective_adjustment no longer computes anything on the halos
17     - removed the warnings about negative salinity from find_rho.F and
18       find_alpha.F; instead the new routine look_for_neg_salinity, called
19       at the beginning of find_rho, find_alpha, and find_beta, does a
20       check of the entire slice, if CPP-option
21       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
22    checkpoint46l_pre
23    
24    checkpoint46k_post
25    o fixed the verification/global_ocean.90x40x15 experiment:
26     - new bathymetry (the world according to A., JMC, and M.)
27     - new initial fields and forcing fields (*.bin files)
28     - new POLY3.COEFFS (for the next release one should switch to a full
29       equation of state: JMD95P or MDJWF)
30     - fixed several errors and redundancies in the data file
31     - experiment uses looped cells
32     - added matlab directory with diagnostic scripts for plotting of output
33    
34    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
35     - read AIM physics parameters from a file (data.aimphys)
36     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
37    
38    checkpoint46j_post
39    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
40    o move wVel computation at the end of the time step, in S/R integr_continuity
41    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
42    o update timeave pkg for wVel diagnostic.
43    checkpoint46j_pre
44    
45    checkpoint46i_post
46    o Clean up AIM package (and keep the results unchanged):
47      include CPP_OPTION and use IMPLICT NONE in all routines ;
48      declare all the variables _RL ; use _d 0 for all numerical constants.
49      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
50    
51    checkpoint46h_post
52    o cleaned up the use of rhoNil and rhoConst.
53      - rhoNil should only appear in the LINEAR equation of state, everywhere
54        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
55        and the dynamical equations are all divided by rhoConst
56    o introduced new parameter rhoConstFresh, a reference density of fresh
57      water, to remove the fresh water flux's dependence on rhoNil. The default
58      value is 999.8 kg/m^3
59    o cleanup up external_forcing.F and external_forcing_surf.F
60      - can now be used by both OCEANIC and OCEANICP
61    checkpoint46h_pre
62    
63     Added code to convert surface volume flux (fresh water) into
64     a mass flux when using P coordinates in the ocean (OCEANICP).
65     Note: It assumes you have set rho0=rhoConst=density of fresh water.
66    
67    checkpoint46g_post
68    o Include a new diagnostic variable phiHydLow for the ocean model
69      - in z-coordinates, it is the bottom pressure anomaly
70      - in p-coordinates, it is the sea surface elevation
71      - in both cases, these variable have global drift, reflecting the mass
72        drift in z-coordinates and the volume drift in p-coordinates
73      - included time averaging for phiHydLow, be aware of the drift!
74    o depth-dependent computation of Bo_surf for pressure coordinates
75      in the ocean (buoyancyRelation='OCEANICP')
76      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
77        Theta, Salinity, and Pressure in the parameter list. This routine is
78        presently contained in find_rho.F. This routine does not give the
79        correct density for 'POLY3', which would be a z-dependent reference
80        density.
81    o cleaned up find_rho
82      - removed obsolete 'eqn' from the parameter list.
83    o added two new verification experiments: gop and goz
84      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
85    checkpoint46g_pre
86    
87    checkpoint46f_post
88    o Enable tangent linear (forward mode) gradient checks:
89      - extended active file handling to g_... files
90      - added TANGENT_SIMULATION to theSimulationMode
91      - extended grdchk package accordingly
92    o added tangent linear setup in verification/carbon/code_ftl
93    o added adjoint setup in verification/front_relax/code_ad
94    
95    checkpoint46e_post
96    o Added new equation of state -> MDJWF
97      - EOS of McDougall et al., 2002, JAOT, submitted
98      - caveat: the equation of state is only valid for a smaller (more
99        realistic?) range of values than JMD95P/Z and UNESCO
100      - added masks to the calculation of pressure in store_pressure
101      - added more check values for density in check_eos (ini_eos.F), some of
102        the old check values are out of the range of the MDJWF-eos, so don't
103        expect perfect matches for those
104    checkpoint46e_pre
105    
106    checkpoint46d_post
107    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
108      'OCEANICP', also initialised field pressure correctly in ini_eos in the
109      case of pressure coordinates. eosType='JMD95Z' in
110      combination with buoyancyRelation='OCEANICP' now causes an error.
111    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
112      in find_alpha/beta.
113    checkpoint46d_pre
114    
115    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
116      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
117    
118    checkpoint46c_post
119    o Changes necessary for ocean in p-coordinates
120     -  Added new buoyancy relation = 'OCEANICP'
121     -  Added new parameters = gravitySign (this used to be contained inside
122        the factor dRdZ which I added when we first switched to R coordinates).
123     X GM/Redi is not compatible (yet)
124     X bottom drag and no-slip need to be debugged.
125    checkpoint46c_pre
126    
127    checkpoint46b_post
128    o Added new equation of state -> JMD95Z and JMD95P
129      - EOS of Jackett and McDougall, 1995, JAOT
130      - moved all EOS parameters into EOS.h
131      - new routines ini_eos.F, store_pressure.F
132    o Added UNESCO EOS, but not recommended because it requires
133      in-situ temperature (see JMD95)
134    o Modified formatting for knudsen2.f in utils/knudsen2 and added
135      unesco.f to be used with POLY3
136    checkpoint46b_pre
137    
138    checkpoint46a_post
139    o Added (atmospheric) pressure loading
140      - new field in FFIELDS.h, etc...
141      - new cpp flag ATMOSPHERIC_LOADING
142    o Changed hFacC to _hFacC in calc_phi_hyd.F

178    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
179    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
180    o change phiMin in exp1 (to agree with documentation)
181    o add new flags:
182     - T,S forcing inside/outside Adams-Bashforth

200    o moved some initialisations within bi,bj loop in dynamics
201      (TAF flow dependency)
202    o in initialise_varia, moved call packages_init_variables
203      before convective_adjustment_init
204      (corresponding adjustment of TAF tape initialisation).
205    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
206    
207    checkpoint45a_post
208    o compute Rho over the whole domain (extend iMin,jMin indices)

226    
227    checkpoint44h_pre
228    o vertical grid option: allow to put the Interface at the middle between

230    o GM Advective form: Tracers are advected using the residual transport (=
231      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
232    
233    checkpoint44g_post
234    o fix surface correction term in multiDimAdvection (affects plume_on_slope
235      results) ; ifdef missing in thermodynamics.F
236    
237    checkpoint44f_pre,checkpoint44f_post
238    o added PTRACERS package
239      This allows an arbitrary number of passive tracers to be integrated
240      forward simultaneously with the dynamicaly model.
241      + Implemented so far:
242        - basic forward algorithm (time-stepping, advection, diffusion, convection)
243        - I/O and checkpointing
244        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
245      + Not implemented so far:
246        - KPP
247        - OBCS
248      + No specific example supplied (yet) but global_ocean.90x40x15 has the
249        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
250        line in data.pkg.
251      + This package is disabled by default since it increases storage.
252    
253    
254    o testscript: added -cleanup option

262      Original calls to convect() still in place.
263    
264    chkpt44d_pre,post
265    o added missing EXCLUDE_MONITOR flags
266    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
267      (incompatible typ in MIN/MAX expressions caused problems
268      on IBM SP3)
269    o in genmake added variable MAKEDEPEND
270      plus resetting for case SunOS
271    o added timer_stats.c routine for IBM SP3
272    o removed variables in dynamics
273    !!! I forgot to create tag chkpt44d_pre !!!

275    
276    o real fresh water flux implemented with non-linear free-surface.
277    
278    chkpt44c_pre,post
279    o few fix (mask in shap_s2, EmPmR in external_field_load,
280      USE_NATURAL_BCS in solve_for_P);
281    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
282    
283    checkpoint44b_pre/_post
284    o merge of relevant stuff from the ecco-branch:
285      - genmake: removed $S64 overwrite for case SunOS
286      - pkg/exf: update and corrections for field swapping and obcs

303    o improve and extend diagnostics (Monitor, TimeAve with NonLin-FrSurf)
304    o added some stuff for AD
305    
306    checkpoint43
307    o added two new advection tests
308    o added global 4x4 degree ocean test

313      Fixed AD-related problems:
314    o Store directives up-to-date with re-arranged Adams-Bashforth
315      (mainly thermodynamics.F)
316    o New store directives for multi-dim. advection schemes
317      * new CPP flag ALLOW_MULTI_DIM_ADVECTION

330    o added FLT (floats) package from Arne along with demo. experiment
331    o re-arranged Adams-Bashforth scheme for tracers to allow easier
332      implementation of forward-in-time forcing terms
333    o more mods for non-linear free-surface including new variable
334    o modified multi-dim method to work on cube
335    o bug fix in KPP (from DM)
336    
337    checkpoint40pre9
338    o added DST advection schemes
339    o fix MPI bug on SGI's
340    o modifications for non-linear free-surface
341    o fixed conditionals for fixed flow/passive tracer only mode
342    o added tension/strain form of stress tensor
343    o changes to commenting of arguments for TAF/TAMC
344    o added/updated many matlab scripts
345    o added multi-dimensional advection method for tracers
346      
347    checkpoint40pre8
348    o new package rw/
349      Added method for dumping intermediate local arrays:
350      mdsio_writetile - same as mdsio_writefield except works from inside
351                        bi,bj loop
352      mdsio_writelocal - same as mdsio_writetile except works for local
353                         arrays
354      write_local_r? - higher-level wrapper for mdsio_writelocal
355      Controlled by diagFreq. Defaults to zero (ie. no dumps)
356      Example given at end of mom_vecinv.F that dumps some local arrays.
357    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
358      control flux-form versus vector invariant code.
359      Switch is runtime flag vectorInvariantMomentum (defaults to false)
360      or genmake -DISABLE ...
361    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
362      (additional storing is now needed for case vecinv;
363      currently nothing implemented to switch this storing off
364      in case fluxform is used since no CPP flag available).
365    
366    checkpoint40pre7
367    o bug fix in dynamics.F
368      calc_viscosity called before k=1,Nr loop.
369    o added some #ifdef's ALLOW_PASSIVE_TRACER

375    o corresponding split of calc_diffusivity into
376      calc_diffusivity, calc_viscosity
377      (kpp_calc_diff, kpp_calc_visc).
378    o Added diffkr, kapgm to control variables
379    o bug fix in gmredi_slope_limit for ldd97
380    
381    checkpoint40pre5
382    o proper initialization of Adams-Bashforth time stepping
383      + uses forward step for very first step of model (iter=0)
384    o re-generated *all* output since almost all output is modified by this
385      change (sorry but we've been putting this one off for about 2 years)
386      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
387        *not* regenerated since they are already out of date and I don't
388        want to create the impression that they are suddenly working.
389    o removed KAP stuff for DEC's
390    o modified/added many .cvsignore files in */code and */input
391    o added new expt "solid-body.cs-32x32x1"
392      + this uses an alternative form of ini_curvilinear_grid.F which
393        is not necessarily any better than the current one...
394    
395    checkpoint40pre4
396    o added re-initialisations of utrans,vtrans,rtrans in
397      calc_common_factors which are crucial for TAF.
398    o extended iMin,jMin range for calc_common_factors,
399      calc_diffusivity

407    
408    checkpoint40pre2
409    o Updated to latest branch of AJA, JMC
410    o Added gradient check package
411    o Added routines for passive tracer handling
412    o Added carbon sequestration sensitivity experiment
