3     Notes on tags used in MITgcmUV
4     ==============================
5 heimbach 1.52
6     checkpoint42
7     Fixed AD-related problems:
8     o Store directives up-to-date with re-arranged Adams-Bashforth
9     (mainly thermodynamics.F)
10     o New store directives for multi-dim. advection schemes
11     * new CPP flag ALLOW_MULTI_DIM_ADVECTION
12     * new common block and key passkey
13     (mainly gad_advection.F)
14     o Modified store directives for split of dynamics/thermodynamics
15     for the case ALLOW_KPP
16     o Cleaned argument list for timestep_tracer.F
17 adcroft 1.51
18     checkpoint41
19     o re-formatted/added comments in prologues of key subroutines
20     to work with protex
21 heimbach 1.47
22 adcroft 1.50 checkpoint40
23     o moved calc_gs, calc_gt and calc_tr1 back to model/src
24     o added FLT (floats) package from Arne along with demo. experiment
25     o re-arranged Adams-Bashforth scheme for tracers to allow easier
26     implementation of forward-in-time forcing terms
27     o more mods for non-linear free-surface including new variable
28     o modified multi-dim method to work on cube
29     o bug fix in KPP (from DM)
30    
31 adcroft 1.49 checkpoint40pre9
32     o added DST advection schemes
33     o fix MPI bug on SGI's
34     o modifications for non-linear free-surface
35     o fixed conditionals for fixed flow/passive tracer only mode
36     o added tension/strain form of stress tensor
37     o changes to commenting of arguments for TAF/TAMC
38     o added/updated many matlab scripts
39 adcroft 1.50 o added multi-dimensional advection method for tracers
40 adcroft 1.49
41 adcroft 1.48 checkpoint40pre8
42 heimbach 1.47 o new package rw/
43     Added method for dumping intermediate local arrays:
44     mdsio_writetile - same as mdsio_writefield except works from inside
45     bi,bj loop
46     mdsio_writelocal - same as mdsio_writetile except works for local
47     arrays
48     write_local_r? - higher-level wrapper for mdsio_writelocal
49     Controlled by diagFreq. Defaults to zero (ie. no dumps)
50     Example given at end of mom_vecinv.F that dumps some local arrays.
51     o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
52     control flux-form versus vector invariant code.
53     Switch is runtime flag vectorInvariantMomentum (defaults to false)
54     or genmake -DISABLE ...
55     o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
56     (additional storing is now needed for case vecinv;
57     currently nothing implemented to switch this storing off
58     in case fluxform is used since no CPP flag available).
59 heimbach 1.46
60     checkpoint40pre7
61     o bug fix in dynamics.F
62     calc_viscosity called before k=1,Nr loop.
63     o added some #ifdef's ALLOW_PASSIVE_TRACER
64     o cleaned initialisations in ctrl_map_ini
65     related to TAF
66 heimbach 1.45
67     checkpoint40pre6
68     o split dynamics into thermodynamics & dynamics
69     o corresponding split of calc_diffusivity into
70     calc_diffusivity, calc_viscosity
71     (kpp_calc_diff, kpp_calc_visc).
72     o Added diffkr, kapgm to control variables
73     o bug fix in gmredi_slope_limit for ldd97
74 adcroft 1.44
75     checkpoint40pre5
76     o proper initialization of Adams-Bashforth time stepping
77     + uses forward step for very first step of model (iter=0)
78     o re-generated *all* output since almost all output is modified by this
79     change (sorry but we've been putting this one off for about 2 years)
80     + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
81     *not* regenerated since they are already out of date and I don't
82     want to create the impression that they are suddenly working.
83     o removed KAP stuff for DEC's
84     o modified/added many .cvsignore files in */code and */input
85     o added new expt "solid-body.cs-32x32x1"
86     + this uses an alternative form of ini_curvilinear_grid.F which
87     is not necessarily any better than the current one...
88 heimbach 1.43
89     checkpoint40pre4
90     o added re-initialisations of utrans,vtrans,rtrans in
91     calc_common_factors which are crucial for TAF.
92     o extended iMin,jMin range for calc_common_factors,
93     calc_diffusivity
94     o added option ALLOW_PASSIVE_TRACER
95     o a few minor updates and fixes
96    
97 heimbach 1.42 checkpoint40pre3
98     o created calc_gtr1.F for gad package
99     o split the_main_loop and re-introduced forward_step
100     o some recomputations of nIter0 for TAMC
101    
102 heimbach 1.41 checkpoint40pre2
103     o Updated to latest branch of AJA, JMC
104     o Added gradient check package
105     o Added routines for passive tracer handling
106     o Added carbon sequestration sensitivity experiment
107    
108 heimbach 1.39 checkpoint39
109     o Modifications and fixes to support TAMC
110     (mainly missing or wrong directives)
111     o Corrected common blocks when fooling TAMC to produce adjoint I/O
112     in addummy_in_stepping
113     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
114     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
115     o Included following packages:
116     cal: calendar
117     exf: external forcing
118     ecco: essential routines to control use of cal, exf
119     (NB: this is not the full ECCO environment)
120 heimbach 1.40 o disabled some packages by default in genmake
121 heimbach 1.39
122 heimbach 1.38 checkpoint38
123     o see notes_c37_adj.txt
124     o corrected wrong layer index in external_forcing_t
125     o replaced the_main_loop/forward_step by the_main_loop
126     o removed forceoutput from write_state
127     (replaced criteria for initial/final state)
128     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
129 jmc 1.36
130 jmc 1.37 checkpoint37
131     o mdsio.F routine split and packaged in pkg/mdsio
132     (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
133     used unless genmake -disable=mdsio)
134     o allow a more precise surface-geopotential gradient for the atmosphere
135     taking into account the change in space of Alpha (=1/rho) at the surface.
136     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
137     (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
138     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
139     Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
140     [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
141     o Time-Average diagnostics defined as a pseudo package "timeave".
142     o pickup files : old pickup (before c35) did not work with new code (c35
143     and after) unless activating 2 commented lines in initialise-varia.
144     o Non-Hydrostatic pickup file Pb fixed.
145     o bug with Rigid-lid version (since c35) fixed.
146    
147 jmc 1.36 checkpoint36
148 jmc 1.37 o implement Crank-Nickelson barotropic time-stepping
149 jmc 1.36 o recover Time-Average diagnostics
150     o fix Pb in checkpoint (PR#19)
151     o AIM become a standard package ; clean unused CPP_kees
152 jmc 1.35
153     checkpoint35
154     o subtantial rewrite of dynamics.f
155     o allows staggered time-stepping
156     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
157     o added bottom drag (linear + quadratic)
158 heimbach 1.33
159     checkpoint34
160     o Modified exchange routines for correct reverse simulation.
161     o Added verification output to comply with bug fix in impldiff.F
162     as of c33 (exp2, natl_box).
163     o Corrected store directives in dynamics.F
164     o Corrected array boundaries in impldiff.F
165     o Corrected array dimensions in gmredi.
166     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
167 heimbach 1.34 o Added routine GLOBAL_SUM_INT to global_sum.F
168 heimbach 1.33 o Added mdsio_gl.F for ECCO purposes.
169 adcroft 1.32
170     checkpoint33
171     o Fixed bug in lower BC in impldiff.F
172     o Fixed confusion about units of forcing arrays in FFIELDS.h
173     namely Fu,Fv,Qnet,Qsw,EmPmR:
174     - Removed verification/natl_box/code/external_fields_scale.F
175     (did not differ from that in model/src)
176     - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
177     (see FFIELDS.h for description)
178     - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
179     kpp_calc.F and kpp_transport_t.F
180     - Removed model/src/external_fields_scale.F and calls to it
181     - verification/natl_box uses flux data with "atmospheric" sign so
182     a special version of external_fields_load.F is used to
183     change the data as it's read in. This way, the arrays
184     have the right units and signs at all times tha a user could
185     possibly use them.
186     o Corrected genmake to delete a temporary file during configuration
187 heimbach 1.31
188     checkpoint32
189     o Scaling of forcing fields moved from external_forcing.F to
190     external_fields_scale.F, called directly after loading fields.
191     o Surface relaxation terms added to surface tendency fields in
192     extra subroutine.
193     o impldiff.F changed to avoid storing by TAMC of huge intermediate
194     fields.
195     o Changes in GMRedi to comply with packaging structure.
196     o Modifications and bug fixes in KPP package.
197     o Verification experiment for KPP added (verification/nat_box/)

202     -> changes in initialise_fixed.F, initialise_varia.F
203     -> enables initialisation interface for ECCO package
204     o Rescaling of external forcing fields immediately after read
205     (removed from external_forcing.F)
206     -> new: surface_fields_scale.F
207     -> affects ini_foorcing.F, external_fields_load.F
208     o Computation of surface tendencies before tendency updates.
209     -> new: external_forcing_surf.F
210     o Change of variable names useGMRedi, useKPP, useECCO
211     o Further changes in dynamics.F, impldiff.F for TAMC

229     o Corrected initialization of hFacMin for difference vertical coordinates
230     o Modified calculation of partial cell thickness to more robust algorithm
231     o config_summary.F: replaced write_1D_... by write_0D_...
232     read_write.F: added subroutines write_0D_...
233     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
234     included some initialisations required for TAMC.
235     o routine calc_isoslopes: modified sqrt computation to make it
236     differentiable for zero argument.
237     o routines dynamics, impldiff:
238     included store directives and tape key computations required for TAMC.
239     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
240 adcroft 1.26
241     checkpoint27
242     o fixed calc_isoslopes() to so that cancellation of terms in tensor
243     formulation works properly with variable resolution.
244     o restructured the calling tree between the_model_main() and dynamics()
245     o split initialise() into initialise_fixed() and initialise_varia()

251     except the argument declarations. This was using up some memory.
252     o fixed macros like _ADT to work with both versions of Linux cpp
253     o cleaned up some unused and uninitialized variables
254     (helps when debugging with strict compile options)
255     o split up CPP_EEOPTIONS.h into options and macros
256     (macros are now in eesupp/inc/CPP_EEMACROS.h)
257     o patch for 2 processor JAM mode
258 adcroft 1.24
259     checkpoint25
260     o updates for OBCs and NH
261     o dramatically reduced memory usage
262     o added "JAM" routines for use on Artic network
263     o parameterization of convection by implicit vertical diffusion
264     o added a diagnostic of convective index
265     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
266     (this is was partly for OBCs and NH but also in anticipation of
267     an explicit free-surface option)

285     o Split-up mid-level I/O routines
286     o Updated input data for experiments 0,1,2,4 and 5
287     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
288 adcroft 1.18
289 adcroft 1.19 checkpoint20
290     o Tidied up open-boundaries some more
291     o Added non-hydrostatic code
292     o Fixed some input data

307     checkpoint17
308     o Beginning to incorporating modularity
309     for supporting atmos. and ocean configs.
310     o Small changes for TAMC complinace

316     accumulation in reverse mode. Adjoint of an
317     assignment is an addition.
318     o Changes to support compilation by TAMC (LR(1)
319     syntax) and by g77 under Linux ( 72 character
320     limit ).
321 cnh 1.14
322     checkpoint15
323     Rewrote exchange routines to allow
324     o General tile <-> tile connectivity.

337     of KGM time-averaging diagnostic errors. Also contains
338     a double-gyre experiment setup as well as the baseline
339     4 degree global template. The double gyre template is
340     organised to allow it to be applied automatically to
341     the baseline configuration.
342 adcroft 1.11
343     branch-point-rdot
344     A few tidy-ups have been made bt the real point of this
345     check-point (excuse the pun) is to allow a branch to be
346     made for the purposes of adding the rDot alterations.
347     I don't want to commit the rDot to the main-trunk until
348     we've actually tested it...
349 cnh 1.10
