3     Notes on tags used in MITgcmUV
4     ==============================
5 heimbach 1.47
6 adcroft 1.48 checkpoint40pre8
7 heimbach 1.47 o new package rw/
8     Added method for dumping intermediate local arrays:
9     mdsio_writetile - same as mdsio_writefield except works from inside
10     bi,bj loop
11     mdsio_writelocal - same as mdsio_writetile except works for local
12     arrays
13     write_local_r? - higher-level wrapper for mdsio_writelocal
14     Controlled by diagFreq. Defaults to zero (ie. no dumps)
15     Example given at end of mom_vecinv.F that dumps some local arrays.
16     o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
17     control flux-form versus vector invariant code.
18     Switch is runtime flag vectorInvariantMomentum (defaults to false)
19     or genmake -DISABLE ...
20     o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
21     (additional storing is now needed for case vecinv;
22     currently nothing implemented to switch this storing off
23     in case fluxform is used since no CPP flag available).
24 heimbach 1.46
25     checkpoint40pre7
26     o bug fix in dynamics.F
27     calc_viscosity called before k=1,Nr loop.
28     o added some #ifdef's ALLOW_PASSIVE_TRACER
29     o cleaned initialisations in ctrl_map_ini
30     related to TAF
31 heimbach 1.45
32     checkpoint40pre6
33     o split dynamics into thermodynamics & dynamics
34     o corresponding split of calc_diffusivity into
35     calc_diffusivity, calc_viscosity
36     (kpp_calc_diff, kpp_calc_visc).
37     o Added diffkr, kapgm to control variables
38     o bug fix in gmredi_slope_limit for ldd97
39 adcroft 1.44
40     checkpoint40pre5
41     o proper initialization of Adams-Bashforth time stepping
42     + uses forward step for very first step of model (iter=0)
43     o re-generated *all* output since almost all output is modified by this
44     change (sorry but we've been putting this one off for about 2 years)
45     + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
46     *not* regenerated since they are already out of date and I don't
47     want to create the impression that they are suddenly working.
48     o removed KAP stuff for DEC's
49     o modified/added many .cvsignore files in */code and */input
50     o added new expt "solid-body.cs-32x32x1"
51     + this uses an alternative form of ini_curvilinear_grid.F which
52     is not necessarily any better than the current one...
53 heimbach 1.43
54     checkpoint40pre4
55     o added re-initialisations of utrans,vtrans,rtrans in
56     calc_common_factors which are crucial for TAF.
57     o extended iMin,jMin range for calc_common_factors,
58     calc_diffusivity
59     o added option ALLOW_PASSIVE_TRACER
60     o a few minor updates and fixes
61    
62 heimbach 1.42 checkpoint40pre3
63     o created calc_gtr1.F for gad package
64     o split the_main_loop and re-introduced forward_step
65     o some recomputations of nIter0 for TAMC
66    
67 heimbach 1.41 checkpoint40pre2
68     o Updated to latest branch of AJA, JMC
69     o Added gradient check package
70     o Added routines for passive tracer handling
71     o Added carbon sequestration sensitivity experiment
72    
73 heimbach 1.39 checkpoint39
74     o Modifications and fixes to support TAMC
75     (mainly missing or wrong directives)
76     o Corrected common blocks when fooling TAMC to produce adjoint I/O
77     in addummy_in_stepping
78     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
79     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
80     o Included following packages:
81     cal: calendar
82     exf: external forcing
83     ecco: essential routines to control use of cal, exf
84     (NB: this is not the full ECCO environment)
85 heimbach 1.40 o disabled some packages by default in genmake
86 heimbach 1.39
87 heimbach 1.38 checkpoint38
88     o see notes_c37_adj.txt
89     o corrected wrong layer index in external_forcing_t
90     o replaced the_main_loop/forward_step by the_main_loop
91     o removed forceoutput from write_state
92     (replaced criteria for initial/final state)
93     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
94 jmc 1.36
95 jmc 1.37 checkpoint37
96     o mdsio.F routine split and packaged in pkg/mdsio
97     (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
98     used unless genmake -disable=mdsio)
99     o allow a more precise surface-geopotential gradient for the atmosphere
100     taking into account the change in space of Alpha (=1/rho) at the surface.
101     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
102     (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
103     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
104     Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
105     [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
106     o Time-Average diagnostics defined as a pseudo package "timeave".
107     o pickup files : old pickup (before c35) did not work with new code (c35
108     and after) unless activating 2 commented lines in initialise-varia.
109     o Non-Hydrostatic pickup file Pb fixed.
110     o bug with Rigid-lid version (since c35) fixed.
111    
112 jmc 1.36 checkpoint36
113 jmc 1.37 o implement Crank-Nickelson barotropic time-stepping
114 jmc 1.36 o recover Time-Average diagnostics
115     o fix Pb in checkpoint (PR#19)
116     o AIM become a standard package ; clean unused CPP_kees
117 jmc 1.35
118     checkpoint35
119     o subtantial rewrite of dynamics.f
120     o allows staggered time-stepping
121     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
122     o added bottom drag (linear + quadratic)
123 heimbach 1.33
124     checkpoint34
125     o Modified exchange routines for correct reverse simulation.
126     o Added verification output to comply with bug fix in impldiff.F
127     as of c33 (exp2, natl_box).
128     o Corrected store directives in dynamics.F
129     o Corrected array boundaries in impldiff.F
130     o Corrected array dimensions in gmredi.
131     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
132 heimbach 1.34 o Added routine GLOBAL_SUM_INT to global_sum.F
133 heimbach 1.33 o Added mdsio_gl.F for ECCO purposes.
134 adcroft 1.32
135     checkpoint33
136     o Fixed bug in lower BC in impldiff.F
137     o Fixed confusion about units of forcing arrays in FFIELDS.h
138     namely Fu,Fv,Qnet,Qsw,EmPmR:
139     - Removed verification/natl_box/code/external_fields_scale.F
140     (did not differ from that in model/src)
141     - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
142     (see FFIELDS.h for description)
143     - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
144     kpp_calc.F and kpp_transport_t.F
145     - Removed model/src/external_fields_scale.F and calls to it
146     - verification/natl_box uses flux data with "atmospheric" sign so
147     a special version of external_fields_load.F is used to
148     change the data as it's read in. This way, the arrays
149     have the right units and signs at all times tha a user could
150     possibly use them.
151     o Corrected genmake to delete a temporary file during configuration
152 heimbach 1.31
153     checkpoint32
154     o Scaling of forcing fields moved from external_forcing.F to
155     external_fields_scale.F, called directly after loading fields.
156     o Surface relaxation terms added to surface tendency fields in
157     extra subroutine.
158     o impldiff.F changed to avoid storing by TAMC of huge intermediate
159     fields.
160     o Changes in GMRedi to comply with packaging structure.
161     o Modifications and bug fixes in KPP package.
162     o Verification experiment for KPP added (verification/nat_box/)
163 heimbach 1.30
164     checkpoint31
165     o Packages interface brought in line with defined standard
166     -> new routines packages_...F
167     -> changes in initialise_fixed.F, initialise_varia.F
168     -> enables initialisation interface for ECCO package
169     o Rescaling of external forcing fields immediately after read
170     (removed from external_forcing.F)
171     -> new: surface_fields_scale.F
172     -> affects ini_foorcing.F, external_fields_load.F
173     o Computation of surface tendencies before tendency updates.
174     -> new: external_forcing_surf.F
175     o Change of variable names useGMRedi, useKPP, useECCO
176     o Further changes in dynamics.F, impldiff.F for TAMC
177     o Tested for experiments 0, 2, 4.
178     - not yet tested for GMRedi.
179     - not yet tested for KPP.

196     o config_summary.F: replaced write_1D_... by write_0D_...
197     read_write.F: added subroutines write_0D_...
198     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
199     included some initialisations required for TAMC.
200     o routine calc_isoslopes: modified sqrt computation to make it
201     differentiable for zero argument.
202     o routines dynamics, impldiff:
203     included store directives and tape key computations required for TAMC.

216     except the argument declarations. This was using up some memory.
217     o fixed macros like _ADT to work with both versions of Linux cpp
218     o cleaned up some unused and uninitialized variables
219     (helps when debugging with strict compile options)
220     o split up CPP_EEOPTIONS.h into options and macros
221     (macros are now in eesupp/inc/CPP_EEMACROS.h)
222     o patch for 2 processor JAM mode
223 adcroft 1.24

229     o added a diagnostic of convective index
230     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
231     (this is was partly for OBCs and NH but also in anticipation of
232     an explicit free-surface option)

265     o Implemented free-slip/no-slip BCs and del^4 dissipation.
266 adcroft 1.19 o Split default parameters out of ini_parms.F into set_defaults.F.
267 cnh 1.17
268     checkpoint18

272     checkpoint17
273     o Beginning to incorporating modularity
274     for supporting atmos. and ocean configs.
275     o Small changes for TAMC complinace

279     checkpoint16
280     o Minor changes to exchange routines to support
281     accumulation in reverse mode. Adjoint of an
282     assignment is an addition.
283     o Changes to support compilation by TAMC (LR(1)
284     syntax) and by g77 under Linux ( 72 character
285     limit ).
286 cnh 1.14
287     checkpoint15
288     Rewrote exchange routines to allow
289     o General tile <-> tile connectivity.
290     o TAMC reverse mode flag ( is this really needed? )
291     o Variable width overlap and exchange region widths.
292     o Hooks for sharing data via DMA, Arctic, Memory Channel,

302     of KGM time-averaging diagnostic errors. Also contains
303     a double-gyre experiment setup as well as the baseline
304     4 degree global template. The double gyre template is
305     organised to allow it to be applied automatically to
306     the baseline configuration.
307 adcroft 1.11
308     branch-point-rdot
309     A few tidy-ups have been made bt the real point of this
310     check-point (excuse the pun) is to allow a branch to be
311     made for the purposes of adding the rDot alterations.
312     I don't want to commit the rDot to the main-trunk until
313     we've actually tested it...
314 cnh 1.10
315     checkpoint12
