3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint40pre5
7    o proper initialization of Adams-Bashforth time stepping
8      + uses forward step for very first step of model (iter=0)
9    o re-generated *all* output since almost all output is modified by this
10      change (sorry but we've been putting this one off for about 2 years)
11      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
12        *not* regenerated since they are already out of date and I don't
13        want to create the impression that they are suddenly working.
14    o removed KAP stuff for DEC's
15    o modified/added many .cvsignore files in */code and */input
16    o added new expt "solid-body.cs-32x32x1"
17      + this uses an alternative form of ini_curvilinear_grid.F which
18        is not necessarily any better than the current one...
19    
20    checkpoint40pre4
21    o added re-initialisations of utrans,vtrans,rtrans in
22      calc_common_factors which are crucial for TAF.
23    o extended iMin,jMin range for calc_common_factors,
24      calc_diffusivity
25    o added option ALLOW_PASSIVE_TRACER
26    o a few minor updates and fixes
27    
28    checkpoint40pre3
29    o created calc_gtr1.F for gad package
30    o split the_main_loop and re-introduced forward_step
31    o some recomputations of nIter0 for TAMC
32    
33    checkpoint40pre2
34    o Updated to latest branch of AJA, JMC
35    o Added gradient check package
36    o Added routines for passive tracer handling
37    o Added carbon sequestration sensitivity experiment
38    
39    checkpoint39
40     o Modifications and fixes to support TAMC
41       (mainly missing or wrong directives)
42     o Corrected common blocks when fooling TAMC to produce adjoint I/O
43       in addummy_in_stepping
44     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
45     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
46     o Included following packages:
47       cal: calendar
48       exf: external forcing
49       ecco: essential routines to control use of cal, exf
50             (NB: this is not the full ECCO environment)
51     o disabled some packages by default in genmake
52    
53    checkpoint38
54     o see notes_c37_adj.txt
55     o corrected wrong layer index in external_forcing_t
56     o replaced the_main_loop/forward_step by the_main_loop
57     o removed forceoutput from write_state
58       (replaced criteria for initial/final state)
59     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
60    
61    checkpoint37
62     o mdsio.F routine split and packaged in pkg/mdsio
63       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
64        used unless genmake -disable=mdsio)
65     o allow a more precise surface-geopotential gradient for the atmosphere
66       taking into account the change in space of Alpha (=1/rho) at the surface.
67     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
68       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
69     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
70       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
71       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
72     o Time-Average diagnostics defined as a pseudo package "timeave".
73     o pickup files : old pickup (before c35) did not work with new code (c35
74       and after) unless activating 2 commented lines in initialise-varia.
75     o Non-Hydrostatic pickup file Pb fixed.
76     o bug with Rigid-lid version (since c35) fixed.  
77    
78  checkpoint36  checkpoint36
79   o implement Crank-Nirotropic time-stepping   o implement Crank-Nickelson barotropic time-stepping
80   o recover Time-Average diagnostics   o recover Time-Average diagnostics
81   o fix Pb in checkpoint (PR#19)   o fix Pb in checkpoint (PR#19)
82   o AIM become a standard package ; clean unused CPP_kees   o AIM become a standard package ; clean unused CPP_kees
