20    
21    checkpoint42
22      Fixed AD-related problems:
23    o Store directives up-to-date with re-arranged Adams-Bashforth
24      (mainly thermodynamics.F)
25    o New store directives for multi-dim. advection schemes
26      * new CPP flag ALLOW_MULTI_DIM_ADVECTION

29    o Modified store directives for split of dynamics/thermodynamics
30      for the case ALLOW_KPP
31    o Cleaned argument list for timestep_tracer.F
32    
33    checkpoint41
34    o re-formatted/added comments in prologues of key subroutines
35      to work with protex
36    
37    checkpoint40
38    o moved calc_gs, calc_gt and calc_tr1 back to model/src
39    o added FLT (floats) package from Arne along with demo. experiment
40    o re-arranged Adams-Bashforth scheme for tracers to allow easier
41      implementation of forward-in-time forcing terms
42    o more mods for non-linear free-surface including new variable
43    o modified multi-dim method to work on cube
44    o bug fix in KPP (from DM)
45    
46    checkpoint40pre9
47    o added DST advection schemes
48    o fix MPI bug on SGI's
49    o modifications for non-linear free-surface
50    o fixed conditionals for fixed flow/passive tracer only mode
51    o added tension/strain form of stress tensor
52    o changes to commenting of arguments for TAF/TAMC
53    o added/updated many matlab scripts
54    o added multi-dimensional advection method for tracers
55      
56    checkpoint40pre8
57    o new package rw/
58      Added method for dumping intermediate local arrays:
59      mdsio_writetile - same as mdsio_writefield except works from inside
60                        bi,bj loop
61      mdsio_writelocal - same as mdsio_writetile except works for local
62                         arrays
63      write_local_r? - higher-level wrapper for mdsio_writelocal
64      Controlled by diagFreq. Defaults to zero (ie. no dumps)
65      Example given at end of mom_vecinv.F that dumps some local arrays.
66    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
67      control flux-form versus vector invariant code.
68      Switch is runtime flag vectorInvariantMomentum (defaults to false)
69      or genmake -DISABLE ...
70    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
71      (additional storing is now needed for case vecinv;
72      currently nothing implemented to switch this storing off
73      in case fluxform is used since no CPP flag available).
74    
75    checkpoint40pre7
76    o bug fix in dynamics.F
77      calc_viscosity called before k=1,Nr loop.
78    o added some #ifdef's ALLOW_PASSIVE_TRACER
79    o cleaned initialisations in ctrl_map_ini
80      related to TAF
81    
82    checkpoint40pre6
83    o split dynamics into thermodynamics & dynamics
84    o corresponding split of calc_diffusivity into
85      calc_diffusivity, calc_viscosity
86      (kpp_calc_diff, kpp_calc_visc).
87    o Added diffkr, kapgm to control variables
88    o bug fix in gmredi_slope_limit for ldd97
89    
90    checkpoint40pre5
91    o proper initialization of Adams-Bashforth time stepping
92      + uses forward step for very first step of model (iter=0)
93    o re-generated *all* output since almost all output is modified by this
94      change (sorry but we've been putting this one off for about 2 years)
95      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
96        *not* regenerated since they are already out of date and I don't
97        want to create the impression that they are suddenly working.
98    o removed KAP stuff for DEC's
99    o modified/added many .cvsignore files in */code and */input
100    o added new expt "solid-body.cs-32x32x1"
101      + this uses an alternative form of ini_curvilinear_grid.F which
102        is not necessarily any better than the current one...
103    
104    checkpoint40pre4
105    o added re-initialisations of utrans,vtrans,rtrans in
106      calc_common_factors which are crucial for TAF.
107    o extended iMin,jMin range for calc_common_factors,
108      calc_diffusivity
109    o added option ALLOW_PASSIVE_TRACER
110    o a few minor updates and fixes
111    
112    checkpoint40pre3
113    o created calc_gtr1.F for gad package
114    o split the_main_loop and re-introduced forward_step
115    o some recomputations of nIter0 for TAMC
116    
117    checkpoint40pre2
118    o Updated to latest branch of AJA, JMC
119    o Added gradient check package
120    o Added routines for passive tracer handling
121    o Added carbon sequestration sensitivity experiment
122    
123    checkpoint39
124     o Modifications and fixes to support TAMC
125       (mainly missing or wrong directives)
126     o Corrected common blocks when fooling TAMC to produce adjoint I/O
127       in addummy_in_stepping
128     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
129     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
130     o Included following packages:
131       cal: calendar
132       exf: external forcing
133       ecco: essential routines to control use of cal, exf
134             (NB: this is not the full ECCO environment)
135     o disabled some packages by default in genmake
136    
137    checkpoint38
138     o see notes_c37_adj.txt
139     o corrected wrong layer index in external_forcing_t
140     o replaced the_main_loop/forward_step by the_main_loop
141     o removed forceoutput from write_state
142       (replaced criteria for initial/final state)
143     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
144    
145    checkpoint37
146     o mdsio.F routine split and packaged in pkg/mdsio
147       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
148        used unless genmake -disable=mdsio)
149     o allow a more precise surface-geopotential gradient for the atmosphere
150       taking into account the change in space of Alpha (=1/rho) at the surface.
151     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
152       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
153     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
154       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
155       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
156     o Time-Average diagnostics defined as a pseudo package "timeave".
157     o pickup files : old pickup (before c35) did not work with new code (c35
158       and after) unless activating 2 commented lines in initialise-varia.
159     o Non-Hydrostatic pickup file Pb fixed.
160     o bug with Rigid-lid version (since c35) fixed.  
161    
162    checkpoint36
163     o implement Crank-Nickelson barotropic time-stepping
164     o recover Time-Average diagnostics
165     o fix Pb in checkpoint (PR#19)
166     o AIM become a standard package ; clean unused CPP_kees
167    
168  checkpoint35  checkpoint35
169   o subtantial rewrite of dynamics.f   o subtantial rewrite of dynamics.f
