3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint41
7    o re-formatted/added comments in prologues of key subroutines
8      to work with protex
9    
10    checkpoint40
11    o moved calc_gs, calc_gt and calc_tr1 back to model/src
12    o added FLT (floats) package from Arne along with demo. experiment
13    o re-arranged Adams-Bashforth scheme for tracers to allow easier
14      implementation of forward-in-time forcing terms
15    o more mods for non-linear free-surface including new variable
16    o modified multi-dim method to work on cube
17    o bug fix in KPP (from DM)
18    
19    checkpoint40pre9
20    o added DST advection schemes
21    o fix MPI bug on SGI's
22    o modifications for non-linear free-surface
23    o fixed conditionals for fixed flow/passive tracer only mode
24    o added tension/strain form of stress tensor
25    o changes to commenting of arguments for TAF/TAMC
26    o added/updated many matlab scripts
27    o added multi-dimensional advection method for tracers
28      
29    checkpoint40pre8
30    o new package rw/
31      Added method for dumping intermediate local arrays:
32      mdsio_writetile - same as mdsio_writefield except works from inside
33                        bi,bj loop
34      mdsio_writelocal - same as mdsio_writetile except works for local
35                         arrays
36      write_local_r? - higher-level wrapper for mdsio_writelocal
37      Controlled by diagFreq. Defaults to zero (ie. no dumps)
38      Example given at end of mom_vecinv.F that dumps some local arrays.
39    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
40      control flux-form versus vector invariant code.
41      Switch is runtime flag vectorInvariantMomentum (defaults to false)
42      or genmake -DISABLE ...
43    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
44      (additional storing is now needed for case vecinv;
45      currently nothing implemented to switch this storing off
46      in case fluxform is used since no CPP flag available).
47    
48    checkpoint40pre7
49    o bug fix in dynamics.F
50      calc_viscosity called before k=1,Nr loop.
51    o added some #ifdef's ALLOW_PASSIVE_TRACER
52    o cleaned initialisations in ctrl_map_ini
53      related to TAF
54    
55    checkpoint40pre6
56    o split dynamics into thermodynamics & dynamics
57    o corresponding split of calc_diffusivity into
58      calc_diffusivity, calc_viscosity
59      (kpp_calc_diff, kpp_calc_visc).
60    o Added diffkr, kapgm to control variables
61    o bug fix in gmredi_slope_limit for ldd97
62    
63    checkpoint40pre5
64    o proper initialization of Adams-Bashforth time stepping
65      + uses forward step for very first step of model (iter=0)
66    o re-generated *all* output since almost all output is modified by this
67      change (sorry but we've been putting this one off for about 2 years)
68      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
69        *not* regenerated since they are already out of date and I don't
70        want to create the impression that they are suddenly working.
71    o removed KAP stuff for DEC's
72    o modified/added many .cvsignore files in */code and */input
73    o added new expt "solid-body.cs-32x32x1"
74      + this uses an alternative form of ini_curvilinear_grid.F which
75        is not necessarily any better than the current one...
76    
77    checkpoint40pre4
78    o added re-initialisations of utrans,vtrans,rtrans in
79      calc_common_factors which are crucial for TAF.
80    o extended iMin,jMin range for calc_common_factors,
81      calc_diffusivity
82    o added option ALLOW_PASSIVE_TRACER
83    o a few minor updates and fixes
84    
85    checkpoint40pre3
86    o created calc_gtr1.F for gad package
87    o split the_main_loop and re-introduced forward_step
88    o some recomputations of nIter0 for TAMC
89    
90    checkpoint40pre2
91    o Updated to latest branch of AJA, JMC
92    o Added gradient check package
93    o Added routines for passive tracer handling
94    o Added carbon sequestration sensitivity experiment
95    
96    checkpoint39
97     o Modifications and fixes to support TAMC
98       (mainly missing or wrong directives)
99     o Corrected common blocks when fooling TAMC to produce adjoint I/O
100       in addummy_in_stepping
101     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
102     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
103     o Included following packages:
104       cal: calendar
105       exf: external forcing
106       ecco: essential routines to control use of cal, exf
107             (NB: this is not the full ECCO environment)
108     o disabled some packages by default in genmake
109    
110    checkpoint38
111     o see notes_c37_adj.txt
112     o corrected wrong layer index in external_forcing_t
113     o replaced the_main_loop/forward_step by the_main_loop
114     o removed forceoutput from write_state
115       (replaced criteria for initial/final state)
116     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
117    
118    checkpoint37
119     o mdsio.F routine split and packaged in pkg/mdsio
120       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
121        used unless genmake -disable=mdsio)
122     o allow a more precise surface-geopotential gradient for the atmosphere
123       taking into account the change in space of Alpha (=1/rho) at the surface.
124     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
125       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
126     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
127       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
128       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
129     o Time-Average diagnostics defined as a pseudo package "timeave".
130     o pickup files : old pickup (before c35) did not work with new code (c35
131       and after) unless activating 2 commented lines in initialise-varia.
132     o Non-Hydrostatic pickup file Pb fixed.
133     o bug with Rigid-lid version (since c35) fixed.  
134    
135  checkpoint36  checkpoint36
136   o implement Crank-Nirotropic time-stepping   o implement Crank-Nickelson barotropic time-stepping
137   o recover Time-Average diagnostics   o recover Time-Average diagnostics
138   o fix Pb in checkpoint (PR#19)   o fix Pb in checkpoint (PR#19)
139   o AIM become a standard package ; clean unused CPP_kees   o AIM become a standard package ; clean unused CPP_kees
