4      ==============================      ==============================
5    
6    checkpoint48a_post
7    o In preparation for r*, use temp. array to compute vertical transport
8       in flux-form momentum pkg. => change results of few test-exp.
9      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
10                        lab_sea, natl_box & plume_on_slope
11    
12    checkpoint48
13    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
14    
15    checkpoint47j_post
16    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
17    o moved adexch from forward_step to addummy_in_stepping
18    o added exch in ctrl_map_...
19    o aveFreq.=0. at end of cost_final to avoid overwrite in
20      reverse checkpointing loop
21    o Yet more changes in gmredi:
22      * adgmredi_calc_tensor
23        avoiding all recomputation of gmredi_slope_limit
24      * adgmredi_x/y/rtransport
25        added flag for excessive storing to avoid recomp. of
26        u/v/rtans, dTdx/y/z
27        -> this is not really necessary and very memory-consuming
28      * adgmredi_slope_psi:
29        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
30      * gmredi_slope_limit
31        re-activated full calculation of taperfct for case 'ac02'
32    o updating verification/ adjoints of carbon, global_ocean.90x40x15
33    
34    checkpoint47i_post
35    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
36    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
37      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
38    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
39    o gmredi: fix few bugs.
40    
41    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
42    This will be a good checkpoint to plug into the ecco-branch.
43    o few modif.'s to get latest version adjointed
44      (mainly kick out code in ini_linear_phisurf)
45    o modif's to run adjoint with exactConserv
46    o case GM_BOLUS_ADVEC should be cleaned
47      S/R gmredi_slope_psi should be cleaned
48    o verification/carbon now has exactConserv=.TRUE.
49    
50    checkpoint47g_post
51    o time-average AIM output: becomes independent from statvars time-average
52      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
53    o After TAF bug fix:
54      Tested adjoint of gmredi package.
55      Tests were done with checkpoint47 rather than with latest
56      checkpoint47f_post since the latter is broken for the adjoint
57      verification/carbon/ contains both ADM and TLM gradient checks.
58    Here they are, before they get changed/lost/stolen.
59    Mostly modif.'s to fix numerical sensitivities.
60    Gradient checks OK for
61    - GM_taper_scheme:
62      * clipping
63      * ac02
64      * linear
65      * glw91
66      * dm95
67      * ldd97
68    - GMREDI_OPTIONS:
69      * GM_VISBECK_VARIABLE_K
70      * GM_NON_UNITY_DIAGONAL
71      * GM_EXTRA_DIAGONAL
72      * GM_BOLUS_ADVEC
73    in conjunction with data.gmredi parameters to be checked in
74    in a few minutes under verification/carbon/code/
75    
76    checkpoint47f_post
77    Merging from release1_p10:
78    o modifications for using pkg/exf with pkg/seaice
79      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
80        and SEAICE_EXTERNAL_FLUXES
81      - pkg/exf CPP options EXF_READ_EVAP and
82        EXF_NO_BULK_COMPUTATIONS
83      - usage examples are Experiments 8 and 9 in
84        verification/lab_sea/README
85      - verification/lab_sea default experiment now uses
86        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
87    
88    checkpoint47e_post
89    o created a tag prior to creating a branch
90    
91    checkpoint47d_post
92    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
93      at the bottom boundary had an erroneous half slip boundary condition
94    o added bottom drag and no slip boundary condition capabilities to
95      oceanic pressure coordinates code
96    o added new verification experiment global_ocean_pressure, this experiment is
97      also described in the tutorial section of the manual
98    checkpoint47d_pre
99    
100    checkpoint47c_post
101    o Added a verification experiment for a global cubed-sphere ocean run
102      -  verification/global_ocean.cubed32x32x30
103      -  uses pkg/therm_seaice and pkg/bulk_forcing
104    
105    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
106    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
107      when using P-coordinate; only implemented for atmospheric config.
108    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
109      NOTES: requires option NONLIN_FRSURF to be "#define".
110    o update advect_xz/results/output.txt (left from checkpoint44g_post)
111    
112    checkpoint47b_post
113    Merging from release1_p9:
114    o pkg/seaice
115      - removed GOTO's and added taf directives
116      - double precision constants to reduce the g77 (Linux)
117        to F77 (SGI) differences reported in release1_p8
118    o tools/genmake
119      - added SGI options
120    o verification/testscript
121      - updated to that of checkpoint47a_post
122    o verification/global_ocean.90x40x15/input/eedata
123      - modified for SGI f77 compatibility
124    o verification/lab_sea
125      - added description of sea-ice model
126      - added missing matlab routines
127      - added test of thermodynamics parallelization
128    
129    checkpoint47a_post
130    o new pkg: aim_v23
131     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
132       for now, keep the same surface forcing as before.
133     - Part-Cell implemented into AIM; check that Heat & Water are conserved
134     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
135     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
136    o add diagnostic of surface correction term in monitor output
137    
138    o bulk_force and therm_seaice
139    - Two packages:  bulk_force (Bulk forcing)
140      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
141    - Earlier integration from Stephaine Dutkiewicz
142      and Patrick Heimbach.
143    - Two ifdef statements for compile time,
144       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
145    
146    checkpoint47
147    differentiable version of checkpoint46n_post
148    o bug fix in quasihydrostaticterms
149    o * "clean" adjoint code (in terms of extensive recomputations)
150        can now be obtained for all GMREDI options (i.e. for
151        - GM_VISBECK_VARIABLE_K
152        - GM_NON_UNITY_DIAGONAL
153        - GM_EXTRA_DIAGONAL
154        - GM_BOLUS_ADVEC )
155      * However, wrong gradient check problem remains unsolved.
156      * New CPP options have been introduced for different
157        tapering schemes
158    o external_fields_load now part of differentiation list
159    o pressure needs multiple storing;
160      would be nice to have store_pressure at beginning or
161      end of forward_step, e.g. by having phiHyd global (5-dim.)
162      (NB: pressure is needed for certain cases in find_rho,
163      which is also invoked through convective_adjustment).
164    o recomputations in find_rho for cases
165     'JMD95'/'UNESCO' or 'MDJWF' are OK.
166    o #define ATMOSPHERIC_LOADING should be differentiable
167    o ini_forcing shifted to begining of initialise_varia
168    o Incorporating QNVS line search routines into MITgcm
169      (this is separate code, and therefore not under pkg)
170      lsopt/, optim/
171    o Updated verification/carbon/
172      - #define GM_VISBECK_VARIABLE_K
173      - GM_taper_scheme    = 'ldd97'    
174    
175    checkpoint46n_post
176    Merging from release1_p8:
177    o verification/natl_box:
178      updating new external_fields_load routine
179    o New package: pkg/seaice
180      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
181      The sea-ice code is based on Hibler (1979-1980).
182      Two sea-ice dynamic solvers, ADI and LSR, are included.
183      In addition to computing prognostic sea-ice variables and diagnosing
184      the forcing/external data fields that drive the ocean model,
185      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
186      The implied surface heat flux is then stored in variable
187      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
188      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
189      non-local transport term.  Because this call precedes model
190      thermodynamics, temperature under sea-ice may not be "exactly" at
191      the freezing point by the time theta is dumped or time-averaged.
192      N.B.: fairly large differences in accuracy occur across
193            different platforms/compilers; comparison between
194            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
195            generated output gives:
196       T           S           U           V
197      C D M    c        m  s        m  s        m  s        m  s
198      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
199      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d

201    
202      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
203    o GAD:
204      - generated new common blocks to account for call of
205        same gad routines with differing traceridentities
206        (needed to modify tracerIdentity indices in GAD.h)
207      - generated separate common blocks for case useCubedSphereExchange
208        (Department of Futurology)
209      - parameter lists to gmredi_?transport: added tracerIdentity
210      - added new key indices to tamc.h
211    o external_fields_load:
212      - added this routine to TAF list
213      - needed to make some common blocks global and additional storing
214        along the same lines as exf package (checkpoint_lev?_directives.h)
215    o exf:
216      updated external forcing package
217      - bug fixes carried over from ecco-branch
218        (missing OBCS_OPTIONS.h in two routines)
219      - enable easy to use "no forcing".
220      - added exf I/O for atmospheric loading
221      - added exf I/O for runoff data
222      - transfered scaling between exf <-> MITgcm to exf namelist
223    o Adding new verification experiment global_with_exf.
224      This verification experiment is almost identical to the
225      global_ocean.90x40x15 experiment, except that it uses
226      the exf (and cal) package instead of the
227      external_fields_load routine (cf README file).
228    
229    checkpoint46m_post
230    o modified testscript to return -- when there are no lines of "%MON" output
231    o added new flag "quasiHydrostatic" for QH mode
232      and new routine quasihydrostaticterms()
233    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
234      New routine: mom_u_coriolis_nh()
235    o fixed sign of non-hydrostatic metric terms in u and v equations.
236      Depend on correct sign of gravitySign.
237    o added work.pc* to .cvsignore in aim directories using ifc
238    o introduced flag for controllin non-hydrostatic metric terms
239    o removed gravitySign from PARM04
240    o switched to g77/ifc from pgf77 in aim experiments
241    
242    checkpoint46l_post
243    o made convective adjustment work with pressure coordinates:
244     - changed the direction of k-loop in convective_adjustment.F for the
245       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
246     - adjusted the reference pressure k-index in convective_adjustment.F
247     - adjusted the convection condition in convect.F (in analogy to
248       calc_ivdc.F)
249     - convective_adjustment no longer computes anything on the halos
250     - removed the warnings about negative salinity from find_rho.F and
251       find_alpha.F; instead the new routine look_for_neg_salinity, called
252       at the beginning of find_rho, find_alpha, and find_beta, does a
253       check of the entire slice, if CPP-option
254       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
255    checkpoint46l_pre
256    
257    checkpoint46k_post
258    o fixed the verification/global_ocean.90x40x15 experiment:
259     - new bathymetry (the world according to A., JMC, and M.)
260     - new initial fields and forcing fields (*.bin files)
261     - new POLY3.COEFFS (for the next release one should switch to a full
262       equation of state: JMD95P or MDJWF)
263     - fixed several errors and redundancies in the data file
264     - experiment uses looped cells
265     - added matlab directory with diagnostic scripts for plotting of output
266    
267    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
268     - read AIM physics parameters from a file (data.aimphys)
269     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
270    
271    checkpoint46j_post
272    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
273    o move wVel computation at the end of the time step, in S/R integr_continuity
274    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
275    o update timeave pkg for wVel diagnostic.
276    checkpoint46j_pre
277    
278    checkpoint46i_post
279    o Clean up AIM package (and keep the results unchanged):
280      include CPP_OPTION and use IMPLICT NONE in all routines ;
281      declare all the variables _RL ; use _d 0 for all numerical constants.
282      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
283    
284    checkpoint46h_post
285    o cleaned up the use of rhoNil and rhoConst.
286      - rhoNil should only appear in the LINEAR equation of state, everywhere
287        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
288        and the dynamical equations are all divided by rhoConst
289    o introduced new parameter rhoConstFresh, a reference density of fresh
290      water, to remove the fresh water flux's dependence on rhoNil. The default
291      value is 999.8 kg/m^3
292    o cleanup up external_forcing.F and external_forcing_surf.F
293      - can now be used by both OCEANIC and OCEANICP
294    checkpoint46h_pre
295    
296     Added code to convert surface volume flux (fresh water) into
297     a mass flux when using P coordinates in the ocean (OCEANICP).
298     Note: It assumes you have set rho0=rhoConst=density of fresh water.
299    
300    checkpoint46g_post
301    o Include a new diagnostic variable phiHydLow for the ocean model
302      - in z-coordinates, it is the bottom pressure anomaly
303      - in p-coordinates, it is the sea surface elevation
304      - in both cases, these variable have global drift, reflecting the mass
305        drift in z-coordinates and the volume drift in p-coordinates
306      - included time averaging for phiHydLow, be aware of the drift!
307    o depth-dependent computation of Bo_surf for pressure coordinates
308      in the ocean (buoyancyRelation='OCEANICP')
309      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
310        Theta, Salinity, and Pressure in the parameter list. This routine is
311        presently contained in find_rho.F. This routine does not give the
312        correct density for 'POLY3', which would be a z-dependent reference
313        density.
314    o cleaned up find_rho
315      - removed obsolete 'eqn' from the parameter list.
316    o added two new verification experiments: gop and goz
317      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
318    checkpoint46g_pre
319    
320    checkpoint46f_post
321    o Enable tangent linear (forward mode) gradient checks:
322      - extended active file handling to g_... files
323      - added TANGENT_SIMULATION to theSimulationMode
324      - extended grdchk package accordingly
325    o added tangent linear setup in verification/carbon/code_ftl
326    o added adjoint setup in verification/front_relax/code_ad
327    
328    checkpoint46e_post
329    o Added new equation of state -> MDJWF
330      - EOS of McDougall et al., 2002, JAOT, submitted
331      - caveat: the equation of state is only valid for a smaller (more
332        realistic?) range of values than JMD95P/Z and UNESCO
333      - added masks to the calculation of pressure in store_pressure
334      - added more check values for density in check_eos (ini_eos.F), some of
335        the old check values are out of the range of the MDJWF-eos, so don't
336        expect perfect matches for those
337    checkpoint46e_pre
338    
339    checkpoint46d_post
340    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
341      'OCEANICP', also initialised field pressure correctly in ini_eos in the
342      case of pressure coordinates. eosType='JMD95Z' in
343      combination with buoyancyRelation='OCEANICP' now causes an error.
344    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
345      in find_alpha/beta.
346    checkpoint46d_pre
347    
348    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
349      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
350    
351    checkpoint46c_post
352    o Changes necessary for ocean in p-coordinates
353     -  Added new buoyancy relation = 'OCEANICP'
354     -  Added new parameters = gravitySign (this used to be contained inside
355        the factor dRdZ which I added when we first switched to R coordinates).
356     X GM/Redi is not compatible (yet)
357     X bottom drag and no-slip need to be debugged.
358    checkpoint46c_pre
359    
360    checkpoint46b_post
361    o Added new equation of state -> JMD95Z and JMD95P
362      - EOS of Jackett and McDougall, 1995, JAOT
363      - moved all EOS parameters into EOS.h
364      - new routines ini_eos.F, store_pressure.F
365    o Added UNESCO EOS, but not recommended because it requires
366      in-situ temperature (see JMD95)
367    o Modified formatting for knudsen2.f in utils/knudsen2 and added
368      unesco.f to be used with POLY3
369    checkpoint46b_pre
370    
371    checkpoint46a_post
372    o Added (atmospheric) pressure loading
373      - new field in FFIELDS.h, etc...
374      - new cpp flag ATMOSPHERIC_LOADING
375    o Changed hFacC to _hFacC in calc_phi_hyd.F
376    o Added SHORTWAVE_HEATING to some files for consistency
377    checkpoint46a_pre
378    
379    checkpoint46
380    further merges from release1_p5
381    o new ctrl package
382      - adopted from ECCO environment to enable optimization
383      - added Eliassen Palm fluxes to controls
384    o added Eliassen Palm flux controls to gradient check package
385    o cost package
386      - Compatible with new ctrl package
387      - added Eliassen Palm cost hooks
388      - modif's of existing cost functions
389    o Adjoint-related bug fixes in kpp:
390      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
391      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
392    o autodiff package
393      - flow directives:
394        + new for S/R do_the_model_io
395        + enhanced for S/R checkpoint
396        + new gmredi.flow
397      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
398        disable adcommon.h/g_common.h by default.
399      - fixed problem for adjoint of global_max
400    o modified verification/carbon/
401    o New setup for adjoint of global_ocean
402    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
403    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
404    o incorporated hooks for sponge layer code (external_forcing.F)
405    
406    checkpoint45d_post
407    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
408    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
409      (affects plume_on_slope "cg2d" output)
