3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint40
7    o moved calc_gs, calc_gt and calc_tr1 back to model/src
8    o added FLT (floats) package from Arne along with demo. experiment
9    o re-arranged Adams-Bashforth scheme for tracers to allow easier
10      implementation of forward-in-time forcing terms
11    o more mods for non-linear free-surface including new variable
12    o modified multi-dim method to work on cube
13    o bug fix in KPP (from DM)
14    
15    checkpoint40pre9
16    o added DST advection schemes
17    o fix MPI bug on SGI's
18    o modifications for non-linear free-surface
19    o fixed conditionals for fixed flow/passive tracer only mode
20    o added tension/strain form of stress tensor
21    o changes to commenting of arguments for TAF/TAMC
22    o added/updated many matlab scripts
23    o added multi-dimensional advection method for tracers
24      
25    checkpoint40pre8
26    o new package rw/
27      Added method for dumping intermediate local arrays:
28      mdsio_writetile - same as mdsio_writefield except works from inside
29                        bi,bj loop
30      mdsio_writelocal - same as mdsio_writetile except works for local
31                         arrays
32      write_local_r? - higher-level wrapper for mdsio_writelocal
33      Controlled by diagFreq. Defaults to zero (ie. no dumps)
34      Example given at end of mom_vecinv.F that dumps some local arrays.
35    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
36      control flux-form versus vector invariant code.
37      Switch is runtime flag vectorInvariantMomentum (defaults to false)
38      or genmake -DISABLE ...
39    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
40      (additional storing is now needed for case vecinv;
41      currently nothing implemented to switch this storing off
42      in case fluxform is used since no CPP flag available).
43    
44    checkpoint40pre7
45    o bug fix in dynamics.F
46      calc_viscosity called before k=1,Nr loop.
47    o added some #ifdef's ALLOW_PASSIVE_TRACER
48    o cleaned initialisations in ctrl_map_ini
49      related to TAF
50    
51    checkpoint40pre6
52    o split dynamics into thermodynamics & dynamics
53    o corresponding split of calc_diffusivity into
54      calc_diffusivity, calc_viscosity
55      (kpp_calc_diff, kpp_calc_visc).
56    o Added diffkr, kapgm to control variables
57    o bug fix in gmredi_slope_limit for ldd97
58    
59    checkpoint40pre5
60    o proper initialization of Adams-Bashforth time stepping
61      + uses forward step for very first step of model (iter=0)
62    o re-generated *all* output since almost all output is modified by this
63      change (sorry but we've been putting this one off for about 2 years)
64      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
65        *not* regenerated since they are already out of date and I don't
66        want to create the impression that they are suddenly working.
67    o removed KAP stuff for DEC's
68    o modified/added many .cvsignore files in */code and */input
69    o added new expt "solid-body.cs-32x32x1"
70      + this uses an alternative form of ini_curvilinear_grid.F which
71        is not necessarily any better than the current one...
72    
73    checkpoint40pre4
74    o added re-initialisations of utrans,vtrans,rtrans in
75      calc_common_factors which are crucial for TAF.
76    o extended iMin,jMin range for calc_common_factors,
77      calc_diffusivity
78    o added option ALLOW_PASSIVE_TRACER
79    o a few minor updates and fixes
80    
81    checkpoint40pre3
82    o created calc_gtr1.F for gad package
83    o split the_main_loop and re-introduced forward_step
84    o some recomputations of nIter0 for TAMC
85    
86    checkpoint40pre2
87    o Updated to latest branch of AJA, JMC
88    o Added gradient check package
89    o Added routines for passive tracer handling
90    o Added carbon sequestration sensitivity experiment
91    
92    checkpoint39
93     o Modifications and fixes to support TAMC
94       (mainly missing or wrong directives)
95     o Corrected common blocks when fooling TAMC to produce adjoint I/O
96       in addummy_in_stepping
97     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
98     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
99     o Included following packages:
100       cal: calendar
101       exf: external forcing
102       ecco: essential routines to control use of cal, exf
103             (NB: this is not the full ECCO environment)
104     o disabled some packages by default in genmake
105    
106    checkpoint38
107     o see notes_c37_adj.txt
108     o corrected wrong layer index in external_forcing_t
109     o replaced the_main_loop/forward_step by the_main_loop
110     o removed forceoutput from write_state
111       (replaced criteria for initial/final state)
112     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
113    
114    checkpoint37
115     o mdsio.F routine split and packaged in pkg/mdsio
116       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
117        used unless genmake -disable=mdsio)
118     o allow a more precise surface-geopotential gradient for the atmosphere
119       taking into account the change in space of Alpha (=1/rho) at the surface.
120     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
121       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
122     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
123       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
124       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
125     o Time-Average diagnostics defined as a pseudo package "timeave".
126     o pickup files : old pickup (before c35) did not work with new code (c35
127       and after) unless activating 2 commented lines in initialise-varia.
128     o Non-Hydrostatic pickup file Pb fixed.
129     o bug with Rigid-lid version (since c35) fixed.  
130    
131    checkpoint36
132     o implement Crank-Nickelson barotropic time-stepping
133     o recover Time-Average diagnostics
134     o fix Pb in checkpoint (PR#19)
135     o AIM become a standard package ; clean unused CPP_kees
136    
137    checkpoint35
138     o subtantial rewrite of dynamics.f
139     o allows staggered time-stepping
140     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
141     o added bottom drag (linear + quadratic)
142    
143    checkpoint34
144     o Modified exchange routines for correct reverse simulation.
145     o Added verification output to comply with bug fix in impldiff.F
146       as of c33 (exp2, natl_box).
147     o Corrected store directives in dynamics.F
148     o Corrected array boundaries in impldiff.F
149     o Corrected array dimensions in gmredi.
150       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
151     o Added routine GLOBAL_SUM_INT to global_sum.F
152     o Added mdsio_gl.F for ECCO purposes.
153    
154  checkpoint33  checkpoint33
155   o Fixed bug in lower BC in impldiff.F   o Fixed bug in lower BC in impldiff.F
