4      ==============================      ==============================
5    
6    checkpoint40
7    o all changes of checkpoint40pre?
8    o new package rw/
9      Added method for dumping intermediate local arrays:
10      mdsio_writetile - same as mdsio_writefield except works from inside
11                        bi,bj loop
12      mdsio_writelocal - same as mdsio_writetile except works for local
13                         arrays
14      write_local_r? - higher-level wrapper for mdsio_writelocal
15      Controlled by diagFreq. Defaults to zero (ie. no dumps)
16      Example given at end of mom_vecinv.F that dumps some local arrays.
17    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
18      control flux-form versus vector invariant code.
19      Switch is runtime flag vectorInvariantMomentum (defaults to false)
20      or genmake -DISABLE ...
21    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
22      (additional storing is now needed for case vecinv;
23      currently nothing implemented to switch this storing off
24      in case fluxform is used since no CPP flag available).
25    
26    checkpoint40pre7
27    o bug fix in dynamics.F
28      calc_viscosity called before k=1,Nr loop.
29    o added some #ifdef's ALLOW_PASSIVE_TRACER
30    o cleaned initialisations in ctrl_map_ini
31      related to TAF
32    
33    checkpoint40pre6
34    o split dynamics into thermodynamics & dynamics
35    o corresponding split of calc_diffusivity into
36      calc_diffusivity, calc_viscosity
37      (kpp_calc_diff, kpp_calc_visc).
38    o Added diffkr, kapgm to control variables
39    o bug fix in gmredi_slope_limit for ldd97
40    
41    checkpoint40pre5
42    o proper initialization of Adams-Bashforth time stepping
43      + uses forward step for very first step of model (iter=0)
44    o re-generated *all* output since almost all output is modified by this
45      change (sorry but we've been putting this one off for about 2 years)
46      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
47        *not* regenerated since they are already out of date and I don't
48        want to create the impression that they are suddenly working.
49    o removed KAP stuff for DEC's
50    o modified/added many .cvsignore files in */code and */input
51    o added new expt "solid-body.cs-32x32x1"
52      + this uses an alternative form of ini_curvilinear_grid.F which
53        is not necessarily any better than the current one...
54    
55    checkpoint40pre4
56    o added re-initialisations of utrans,vtrans,rtrans in
57      calc_common_factors which are crucial for TAF.
58    o extended iMin,jMin range for calc_common_factors,
59      calc_diffusivity
60    o added option ALLOW_PASSIVE_TRACER
61    o a few minor updates and fixes
62    
63    checkpoint40pre3
64    o created calc_gtr1.F for gad package
65    o split the_main_loop and re-introduced forward_step
66    o some recomputations of nIter0 for TAMC
67    
68    checkpoint40pre2
69    o Updated to latest branch of AJA, JMC
70    o Added gradient check package
71    o Added routines for passive tracer handling
72    o Added carbon sequestration sensitivity experiment
73    
74    checkpoint39
75     o Modifications and fixes to support TAMC
76       (mainly missing or wrong directives)
77     o Corrected common blocks when fooling TAMC to produce adjoint I/O
78       in addummy_in_stepping
79     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
80     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
81     o Included following packages:
82       cal: calendar
83       exf: external forcing
84       ecco: essential routines to control use of cal, exf
85             (NB: this is not the full ECCO environment)
86     o disabled some packages by default in genmake
87    
88    checkpoint38
89     o see notes_c37_adj.txt
90     o corrected wrong layer index in external_forcing_t
91     o replaced the_main_loop/forward_step by the_main_loop
92     o removed forceoutput from write_state
93       (replaced criteria for initial/final state)
94     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
95    
96    checkpoint37
97     o mdsio.F routine split and packaged in pkg/mdsio
98       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
99        used unless genmake -disable=mdsio)
100     o allow a more precise surface-geopotential gradient for the atmosphere
101       taking into account the change in space of Alpha (=1/rho) at the surface.
102     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
103       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
104     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
105       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
106       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
107     o Time-Average diagnostics defined as a pseudo package "timeave".
108     o pickup files : old pickup (before c35) did not work with new code (c35
109       and after) unless activating 2 commented lines in initialise-varia.
110     o Non-Hydrostatic pickup file Pb fixed.
111     o bug with Rigid-lid version (since c35) fixed.  
112    
113    checkpoint36
114     o implement Crank-Nickelson barotropic time-stepping
115     o recover Time-Average diagnostics
116     o fix Pb in checkpoint (PR#19)
117     o AIM become a standard package ; clean unused CPP_kees
118    
119    checkpoint35
120     o subtantial rewrite of dynamics.f
121     o allows staggered time-stepping
122     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
123     o added bottom drag (linear + quadratic)
124    
125  checkpoint34  checkpoint34
126   o Modified exchange routines for correct reverse simulation.   o Modified exchange routines for correct reverse simulation.
127   o Added verification output to comply with bug fix in impldiff.F   o Added verification output to comply with bug fix in impldiff.F

130   o Corrected array boundaries in impldiff.F   o Corrected array boundaries in impldiff.F
131   o Corrected array dimensions in gmredi.   o Corrected array dimensions in gmredi.
132     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
