4      ==============================      ==============================
5    
6    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
7      New routine: mom_u_coriolis_nh()
8    o fixed sign of non-hydrostatic metric terms in u and v equations.
9      Depend on correct sign of gravitySign.
10    o added work.pc* to .cvsignore in aim directories using ifc
11    o introduced flag for controllin non-hydrostatic metric terms
12    o removed gravitySign from PARM04
13    o switched to g77/ifc from pgf77 in aim experiments
14    
15    checkpoint46l_post
16    o made convective adjustment work with pressure coordinates:
17     - changed the direction of k-loop in convective_adjustment.F for the
18       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
19     - adjusted the reference pressure k-index in convective_adjustment.F
20     - adjusted the convection condition in convect.F (in analogy to
21       calc_ivdc.F)
22     - convective_adjustment no longer computes anything on the halos
23     - removed the warnings about negative salinity from find_rho.F and
24       find_alpha.F; instead the new routine look_for_neg_salinity, called
25       at the beginning of find_rho, find_alpha, and find_beta, does a
26       check of the entire slice, if CPP-option
27       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
28    checkpoint46l_pre
29    
30    checkpoint46k_post
31    o fixed the verification/global_ocean.90x40x15 experiment:
32     - new bathymetry (the world according to A., JMC, and M.)
33     - new initial fields and forcing fields (*.bin files)
34     - new POLY3.COEFFS (for the next release one should switch to a full
35       equation of state: JMD95P or MDJWF)
36     - fixed several errors and redundancies in the data file
37     - experiment uses looped cells
38     - added matlab directory with diagnostic scripts for plotting of output
39    
40    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
41     - read AIM physics parameters from a file (data.aimphys)
42     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
43    
44    checkpoint46j_post
45    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
46    o move wVel computation at the end of the time step, in S/R integr_continuity
47    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
48    o update timeave pkg for wVel diagnostic.
49    checkpoint46j_pre
50    
51    checkpoint46i_post
52    o Clean up AIM package (and keep the results unchanged):
53      include CPP_OPTION and use IMPLICT NONE in all routines ;
54      declare all the variables _RL ; use _d 0 for all numerical constants.
55      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
56    
57    checkpoint46h_post
58    o cleaned up the use of rhoNil and rhoConst.
59      - rhoNil should only appear in the LINEAR equation of state, everywhere
60        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
61        and the dynamical equations are all divided by rhoConst
62    o introduced new parameter rhoConstFresh, a reference density of fresh
63      water, to remove the fresh water flux's dependence on rhoNil. The default
64      value is 999.8 kg/m^3
65    o cleanup up external_forcing.F and external_forcing_surf.F
66      - can now be used by both OCEANIC and OCEANICP
67    checkpoint46h_pre
68    
69     Added code to convert surface volume flux (fresh water) into
70     a mass flux when using P coordinates in the ocean (OCEANICP).
71     Note: It assumes you have set rho0=rhoConst=density of fresh water.
72    
73    checkpoint46g_post
74    o Include a new diagnostic variable phiHydLow for the ocean model
75      - in z-coordinates, it is the bottom pressure anomaly
76      - in p-coordinates, it is the sea surface elevation
77      - in both cases, these variable have global drift, reflecting the mass
78        drift in z-coordinates and the volume drift in p-coordinates
79      - included time averaging for phiHydLow, be aware of the drift!
80    o depth-dependent computation of Bo_surf for pressure coordinates
81      in the ocean (buoyancyRelation='OCEANICP')
82      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
83        Theta, Salinity, and Pressure in the parameter list. This routine is
84        presently contained in find_rho.F. This routine does not give the
85        correct density for 'POLY3', which would be a z-dependent reference
86        density.
87    o cleaned up find_rho
88      - removed obsolete 'eqn' from the parameter list.
89    o added two new verification experiments: gop and goz
90      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
91    checkpoint46g_pre
92    
93    checkpoint46f_post
94    o Enable tangent linear (forward mode) gradient checks:
95      - extended active file handling to g_... files
96      - added TANGENT_SIMULATION to theSimulationMode
97      - extended grdchk package accordingly
98    o added tangent linear setup in verification/carbon/code_ftl
99    o added adjoint setup in verification/front_relax/code_ad
100    
101    checkpoint46e_post
102    o Added new equation of state -> MDJWF
103      - EOS of McDougall et al., 2002, JAOT, submitted
104      - caveat: the equation of state is only valid for a smaller (more
105        realistic?) range of values than JMD95P/Z and UNESCO
106      - added masks to the calculation of pressure in store_pressure
107      - added more check values for density in check_eos (ini_eos.F), some of
108        the old check values are out of the range of the MDJWF-eos, so don't
109        expect perfect matches for those
110    checkpoint46e_pre
111    
112    checkpoint46d_post
113    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
114      'OCEANICP', also initialised field pressure correctly in ini_eos in the
115      case of pressure coordinates. eosType='JMD95Z' in
116      combination with buoyancyRelation='OCEANICP' now causes an error.
117    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
118      in find_alpha/beta.
119    checkpoint46d_pre
120    
121    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
122      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
123    
124    checkpoint46c_post
125    o Changes necessary for ocean in p-coordinates
126     -  Added new buoyancy relation = 'OCEANICP'
127     -  Added new parameters = gravitySign (this used to be contained inside
128        the factor dRdZ which I added when we first switched to R coordinates).
129     X GM/Redi is not compatible (yet)
130     X bottom drag and no-slip need to be debugged.
131    checkpoint46c_pre
132    
133    checkpoint46b_post
134    o Added new equation of state -> JMD95Z and JMD95P
135      - EOS of Jackett and McDougall, 1995, JAOT
136      - moved all EOS parameters into EOS.h
137      - new routines ini_eos.F, store_pressure.F
138    o Added UNESCO EOS, but not recommended because it requires
139      in-situ temperature (see JMD95)
140    o Modified formatting for knudsen2.f in utils/knudsen2 and added
141      unesco.f to be used with POLY3
142    checkpoint46b_pre
143    
144    checkpoint46a_post
145    o Added (atmospheric) pressure loading
146      - new field in FFIELDS.h, etc...
147      - new cpp flag ATMOSPHERIC_LOADING
148    o Changed hFacC to _hFacC in calc_phi_hyd.F
149    o Added SHORTWAVE_HEATING to some files for consistency
150    checkpoint46a_pre
151    
152    checkpoint46
153    further merges from release1_p5
154    o new ctrl package
155      - adopted from ECCO environment to enable optimization
156      - added Eliassen Palm fluxes to controls
157    o added Eliassen Palm flux controls to gradient check package
158    o cost package
159      - Compatible with new ctrl package
160      - added Eliassen Palm cost hooks
161      - modif's of existing cost functions
162    o Adjoint-related bug fixes in kpp:
163      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
164      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
165    o autodiff package
166      - flow directives:
167        + new for S/R do_the_model_io
168        + enhanced for S/R checkpoint
169        + new gmredi.flow
170      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
171        disable adcommon.h/g_common.h by default.
172      - fixed problem for adjoint of global_max
173    o modified verification/carbon/
174    o New setup for adjoint of global_ocean

177    o incorporated hooks for sponge layer code (external_forcing.F)
178    
179    checkpoint45d_post
180    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
181    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
182      (affects plume_on_slope "cg2d" output)
183    o add new parameter deltaTfreesurf for free-surface time stepping
184    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
