3     Notes on tags used in MITgcmUV
4     ==============================
5 heimbach 1.47
6     checkpoint40
7     o all changes of checkpoint40pre?
8     o new package rw/
9     Added method for dumping intermediate local arrays:
10     mdsio_writetile - same as mdsio_writefield except works from inside
11     bi,bj loop
12     mdsio_writelocal - same as mdsio_writetile except works for local
13     arrays
14     write_local_r? - higher-level wrapper for mdsio_writelocal
15     Controlled by diagFreq. Defaults to zero (ie. no dumps)
16     Example given at end of mom_vecinv.F that dumps some local arrays.
17     o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
18     control flux-form versus vector invariant code.
19     Switch is runtime flag vectorInvariantMomentum (defaults to false)
20     or genmake -DISABLE ...
21     o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
22     (additional storing is now needed for case vecinv;
23     currently nothing implemented to switch this storing off
24     in case fluxform is used since no CPP flag available).
25 heimbach 1.46
26     checkpoint40pre7
27     o bug fix in dynamics.F
28     calc_viscosity called before k=1,Nr loop.
29     o added some #ifdef's ALLOW_PASSIVE_TRACER
30     o cleaned initialisations in ctrl_map_ini
31     related to TAF
32 heimbach 1.45
33     checkpoint40pre6
34     o split dynamics into thermodynamics & dynamics
35     o corresponding split of calc_diffusivity into
36     calc_diffusivity, calc_viscosity
37     (kpp_calc_diff, kpp_calc_visc).
38     o Added diffkr, kapgm to control variables
39     o bug fix in gmredi_slope_limit for ldd97
40 adcroft 1.44
41     checkpoint40pre5
42     o proper initialization of Adams-Bashforth time stepping
43     + uses forward step for very first step of model (iter=0)
44     o re-generated *all* output since almost all output is modified by this
45     change (sorry but we've been putting this one off for about 2 years)
46     + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
47     *not* regenerated since they are already out of date and I don't
48     want to create the impression that they are suddenly working.
49     o removed KAP stuff for DEC's
50     o modified/added many .cvsignore files in */code and */input
51     o added new expt "solid-body.cs-32x32x1"
52     + this uses an alternative form of ini_curvilinear_grid.F which
53     is not necessarily any better than the current one...
54 heimbach 1.43
55     checkpoint40pre4
56     o added re-initialisations of utrans,vtrans,rtrans in
57     calc_common_factors which are crucial for TAF.
58     o extended iMin,jMin range for calc_common_factors,
59     calc_diffusivity
60     o added option ALLOW_PASSIVE_TRACER
61     o a few minor updates and fixes
62    
63 heimbach 1.42 checkpoint40pre3
64     o created calc_gtr1.F for gad package
65     o split the_main_loop and re-introduced forward_step
66     o some recomputations of nIter0 for TAMC
67    
68 heimbach 1.41 checkpoint40pre2
69     o Updated to latest branch of AJA, JMC
70     o Added gradient check package
71     o Added routines for passive tracer handling
72     o Added carbon sequestration sensitivity experiment
73    
74 heimbach 1.39 checkpoint39
75     o Modifications and fixes to support TAMC
76     (mainly missing or wrong directives)
77     o Corrected common blocks when fooling TAMC to produce adjoint I/O
78     in addummy_in_stepping
79     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
80     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
81     o Included following packages:
82     cal: calendar
83     exf: external forcing
84     ecco: essential routines to control use of cal, exf
85     (NB: this is not the full ECCO environment)
86 heimbach 1.40 o disabled some packages by default in genmake
87 heimbach 1.39
88 heimbach 1.38 checkpoint38
89     o see notes_c37_adj.txt
90     o corrected wrong layer index in external_forcing_t
91     o replaced the_main_loop/forward_step by the_main_loop
92     o removed forceoutput from write_state
93     (replaced criteria for initial/final state)
94     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
95 jmc 1.36
96 jmc 1.37 checkpoint37
97     o mdsio.F routine split and packaged in pkg/mdsio
98     (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
99     used unless genmake -disable=mdsio)
100     o allow a more precise surface-geopotential gradient for the atmosphere
101     taking into account the change in space of Alpha (=1/rho) at the surface.
102     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
103     (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
104     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
105     Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
106     [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
107     o Time-Average diagnostics defined as a pseudo package "timeave".
108     o pickup files : old pickup (before c35) did not work with new code (c35
109     and after) unless activating 2 commented lines in initialise-varia.
110     o Non-Hydrostatic pickup file Pb fixed.
111     o bug with Rigid-lid version (since c35) fixed.
112    
113 jmc 1.36 checkpoint36
114 jmc 1.37 o implement Crank-Nickelson barotropic time-stepping
115 jmc 1.36 o recover Time-Average diagnostics
116     o fix Pb in checkpoint (PR#19)
117     o AIM become a standard package ; clean unused CPP_kees
118 jmc 1.35
119     checkpoint35
120     o subtantial rewrite of dynamics.f
121     o allows staggered time-stepping
122     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
123     o added bottom drag (linear + quadratic)
124 heimbach 1.33
125     checkpoint34
126     o Modified exchange routines for correct reverse simulation.
127     o Added verification output to comply with bug fix in impldiff.F
128     as of c33 (exp2, natl_box).
129     o Corrected store directives in dynamics.F
130     o Corrected array boundaries in impldiff.F
131     o Corrected array dimensions in gmredi.
132     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
133 heimbach 1.34 o Added routine GLOBAL_SUM_INT to global_sum.F
134 heimbach 1.33 o Added mdsio_gl.F for ECCO purposes.
135 adcroft 1.32
136     checkpoint33
137     o Fixed bug in lower BC in impldiff.F
138     o Fixed confusion about units of forcing arrays in FFIELDS.h
139     namely Fu,Fv,Qnet,Qsw,EmPmR:
140     - Removed verification/natl_box/code/external_fields_scale.F
141     (did not differ from that in model/src)
142     - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
143     (see FFIELDS.h for description)
144     - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
145     kpp_calc.F and kpp_transport_t.F
146     - Removed model/src/external_fields_scale.F and calls to it
147     - verification/natl_box uses flux data with "atmospheric" sign so
148     a special version of external_fields_load.F is used to
149     change the data as it's read in. This way, the arrays
150     have the right units and signs at all times tha a user could
151     possibly use them.
152     o Corrected genmake to delete a temporary file during configuration
153 heimbach 1.31
154     checkpoint32
155     o Scaling of forcing fields moved from external_forcing.F to
156     external_fields_scale.F, called directly after loading fields.
157     o Surface relaxation terms added to surface tendency fields in
158     extra subroutine.
159     o impldiff.F changed to avoid storing by TAMC of huge intermediate
160     fields.
161     o Changes in GMRedi to comply with packaging structure.
162     o Modifications and bug fixes in KPP package.
163     o Verification experiment for KPP added (verification/nat_box/)
164 heimbach 1.30
165     checkpoint31
166     o Packages interface brought in line with defined standard
167     -> new routines packages_...F
168     -> changes in initialise_fixed.F, initialise_varia.F
169     -> enables initialisation interface for ECCO package
170     o Rescaling of external forcing fields immediately after read
171     (removed from external_forcing.F)
172     -> new: surface_fields_scale.F
173     -> affects ini_foorcing.F, external_fields_load.F
174     o Computation of surface tendencies before tendency updates.
175     -> new: external_forcing_surf.F
176     o Change of variable names useGMRedi, useKPP, useECCO
177     o Further changes in dynamics.F, impldiff.F for TAMC
178     o Tested for experiments 0, 2, 4.

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

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

266     o Implemented free-slip/no-slip BCs and del^4 dissipation.
267 adcroft 1.19 o Split default parameters out of ini_parms.F into set_defaults.F.
268 cnh 1.17
269     checkpoint18
270     o Further changes for optional code generation with
271     CPP - ugh!
272 cnh 1.16
273     checkpoint17
274     o Beginning to incorporating modularity
275     for supporting atmos. and ocean configs.
276     o Small changes for TAMC complinace

280     checkpoint16
281     o Minor changes to exchange routines to support
282     accumulation in reverse mode. Adjoint of an
283     assignment is an addition.
284     o Changes to support compilation by TAMC (LR(1)
285     syntax) and by g77 under Linux ( 72 character
286     limit ).
287 cnh 1.14
288     checkpoint15
289     Rewrote exchange routines to allow
290     o General tile <-> tile connectivity.

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