3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint40pre9
7    o added DST advection schemes
8    o fix MPI bug on SGI's
9    o modifications for non-linear free-surface
10    o fixed conditionals for fixed flow/passive tracer only mode
11    o added tension/strain form of stress tensor
12    o changes to commenting of arguments for TAF/TAMC
13    o added/updated many matlab scripts
14      
15    checkpoint40pre8
16    o new package rw/
17      Added method for dumping intermediate local arrays:
18      mdsio_writetile - same as mdsio_writefield except works from inside
19                        bi,bj loop
20      mdsio_writelocal - same as mdsio_writetile except works for local
21                         arrays
22      write_local_r? - higher-level wrapper for mdsio_writelocal
23      Controlled by diagFreq. Defaults to zero (ie. no dumps)
24      Example given at end of mom_vecinv.F that dumps some local arrays.
25    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
26      control flux-form versus vector invariant code.
27      Switch is runtime flag vectorInvariantMomentum (defaults to false)
28      or genmake -DISABLE ...
29    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
30      (additional storing is now needed for case vecinv;
31      currently nothing implemented to switch this storing off
32      in case fluxform is used since no CPP flag available).
33    
34    checkpoint40pre7
35    o bug fix in dynamics.F
36      calc_viscosity called before k=1,Nr loop.
37    o added some #ifdef's ALLOW_PASSIVE_TRACER
38    o cleaned initialisations in ctrl_map_ini
39      related to TAF
40    
41    checkpoint40pre6
42    o split dynamics into thermodynamics & dynamics
43    o corresponding split of calc_diffusivity into
44      calc_diffusivity, calc_viscosity
45      (kpp_calc_diff, kpp_calc_visc).
46    o Added diffkr, kapgm to control variables
47    o bug fix in gmredi_slope_limit for ldd97
48    
49    checkpoint40pre5
50    o proper initialization of Adams-Bashforth time stepping
51      + uses forward step for very first step of model (iter=0)
52    o re-generated *all* output since almost all output is modified by this
53      change (sorry but we've been putting this one off for about 2 years)
54      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
55        *not* regenerated since they are already out of date and I don't
56        want to create the impression that they are suddenly working.
57    o removed KAP stuff for DEC's
58    o modified/added many .cvsignore files in */code and */input
59    o added new expt "solid-body.cs-32x32x1"
60      + this uses an alternative form of ini_curvilinear_grid.F which
61        is not necessarily any better than the current one...
62    
63    checkpoint40pre4
64    o added re-initialisations of utrans,vtrans,rtrans in
65      calc_common_factors which are crucial for TAF.
66    o extended iMin,jMin range for calc_common_factors,
67      calc_diffusivity
68    o added option ALLOW_PASSIVE_TRACER
69    o a few minor updates and fixes
70    
71    checkpoint40pre3
72    o created calc_gtr1.F for gad package
73    o split the_main_loop and re-introduced forward_step
74    o some recomputations of nIter0 for TAMC
75    
76    checkpoint40pre2
77    o Updated to latest branch of AJA, JMC
78    o Added gradient check package
79    o Added routines for passive tracer handling
80    o Added carbon sequestration sensitivity experiment
81    
82    checkpoint39
83     o Modifications and fixes to support TAMC
84       (mainly missing or wrong directives)
85     o Corrected common blocks when fooling TAMC to produce adjoint I/O
86       in addummy_in_stepping
87     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
88     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
89     o Included following packages:
90       cal: calendar
91       exf: external forcing
92       ecco: essential routines to control use of cal, exf
93             (NB: this is not the full ECCO environment)
94     o disabled some packages by default in genmake
95    
96    checkpoint38
97     o see notes_c37_adj.txt
98     o corrected wrong layer index in external_forcing_t
99     o replaced the_main_loop/forward_step by the_main_loop
100     o removed forceoutput from write_state
101       (replaced criteria for initial/final state)
102     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
103    
104    checkpoint37
105     o mdsio.F routine split and packaged in pkg/mdsio
106       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
107        used unless genmake -disable=mdsio)
108     o allow a more precise surface-geopotential gradient for the atmosphere
109       taking into account the change in space of Alpha (=1/rho) at the surface.
110     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
111       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
112     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
113       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
114       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
115     o Time-Average diagnostics defined as a pseudo package "timeave".
116     o pickup files : old pickup (before c35) did not work with new code (c35
117       and after) unless activating 2 commented lines in initialise-varia.
118     o Non-Hydrostatic pickup file Pb fixed.
119     o bug with Rigid-lid version (since c35) fixed.  
120    
121    checkpoint36
122     o implement Crank-Nickelson barotropic time-stepping
123     o recover Time-Average diagnostics
124     o fix Pb in checkpoint (PR#19)
125     o AIM become a standard package ; clean unused CPP_kees
126    
127    checkpoint35
128     o subtantial rewrite of dynamics.f
129     o allows staggered time-stepping
130     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
131     o added bottom drag (linear + quadratic)
132    
133    checkpoint34
134     o Modified exchange routines for correct reverse simulation.
135     o Added verification output to comply with bug fix in impldiff.F
136       as of c33 (exp2, natl_box).
137     o Corrected store directives in dynamics.F
138     o Corrected array boundaries in impldiff.F
139     o Corrected array dimensions in gmredi.
140       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
141     o Added routine GLOBAL_SUM_INT to global_sum.F
142     o Added mdsio_gl.F for ECCO purposes.
143    
144    checkpoint33
145     o Fixed bug in lower BC in impldiff.F
146     o Fixed confusion about units of forcing arrays in FFIELDS.h
147       namely Fu,Fv,Qnet,Qsw,EmPmR:
148       - Removed verification/natl_box/code/external_fields_scale.F
149         (did not differ from that in model/src)
150       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
151         (see FFIELDS.h for description)
152       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
153         kpp_calc.F and kpp_transport_t.F
154       - Removed model/src/external_fields_scale.F and calls to it
155       - verification/natl_box uses flux data with "atmospheric" sign so
156         a special version of external_fields_load.F is used to
157         change the data as it's read in. This way, the arrays
158         have the right units and signs at all times tha a user could
159         possibly use them.
160     o Corrected genmake to delete a temporary file during configuration
161    
162  checkpoint32  checkpoint32
163   o Scaling of forcing fields moved from external_forcing.F to   o Scaling of forcing fields moved from external_forcing.F to
164     external_fields_scale.F, called directly after loading fields.     external_fields_scale.F, called directly after loading fields.
