4      ==============================      ==============================
5    
6    checkpoint35
7     o subtantial rewrite of dynamics.f
8     o allows staggered time-stepping
9     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
10     o added bottom drag (linear + quadratic)
11    
12    checkpoint34
13     o Modified exchange routines for correct reverse simulation.
14     o Added verification output to comply with bug fix in impldiff.F
15       as of c33 (exp2, natl_box).
16     o Corrected store directives in dynamics.F
17     o Corrected array boundaries in impldiff.F
18     o Corrected array dimensions in gmredi.
19       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
20     o Added routine GLOBAL_SUM_INT to global_sum.F
21     o Added mdsio_gl.F for ECCO purposes.
22    
23    checkpoint33
24     o Fixed bug in lower BC in impldiff.F
25     o Fixed confusion about units of forcing arrays in FFIELDS.h
26       namely Fu,Fv,Qnet,Qsw,EmPmR:
27       - Removed verification/natl_box/code/external_fields_scale.F
28         (did not differ from that in model/src)
29       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
30         (see FFIELDS.h for description)
31       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
32         kpp_calc.F and kpp_transport_t.F
33       - Removed model/src/external_fields_scale.F and calls to it
34       - verification/natl_box uses flux data with "atmospheric" sign so
35         a special version of external_fields_load.F is used to
36         change the data as it's read in. This way, the arrays
37         have the right units and signs at all times tha a user could
38         possibly use them.
39     o Corrected genmake to delete a temporary file during configuration
40    
41    checkpoint32
42     o Scaling of forcing fields moved from external_forcing.F to
43       external_fields_scale.F, called directly after loading fields.
44     o Surface relaxation terms added to surface tendency fields in
45       extra subroutine.
46     o impldiff.F changed to avoid storing by TAMC of huge intermediate
47       fields.
48     o Changes in GMRedi to comply with packaging structure.
49     o Modifications and bug fixes in KPP package.
50     o Verification experiment for KPP added (verification/nat_box/)
51    
52    checkpoint31
53     o Packages interface brought in line with defined standard
54       -> new routines packages_...F
55       -> changes in initialise_fixed.F, initialise_varia.F
56       -> enables initialisation interface for ECCO package
57     o Rescaling of external forcing fields immediately after read
58       (removed from external_forcing.F)
59       -> new: surface_fields_scale.F
60       -> affects ini_foorcing.F, external_fields_load.F
61     o Computation of surface tendencies before tendency updates.
62       -> new: external_forcing_surf.F
63     o Change of variable names useGMRedi, useKPP, useECCO
64     o Further changes in dynamics.F, impldiff.F for TAMC
65     o Tested for experiments 0, 2, 4.

74       kpp_dumpFreq and kpp_taveFreq
75     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)

80    
81    checkpoint28
82     o Corrected initialization of hFacMin for difference vertical coordinates
83     o Modified calculation of partial cell thickness to more robust algorithm
84     o config_summary.F: replaced write_1D_... by write_0D_...
85       read_write.F: added subroutines write_0D_...
86     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
87       included some initialisations required for TAMC.
88     o routine calc_isoslopes: modified sqrt computation to make it
89       differentiable for zero argument.
90     o routines dynamics, impldiff:
91       included store directives and tape key computations required for TAMC.
92     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
93    
94    checkpoint27
95     o fixed calc_isoslopes() to so that cancellation of terms in tensor
96       formulation works properly with variable resolution.

104       except the argument declarations. This was using up some memory.
105     o fixed macros like _ADT to work with both versions of Linux cpp
106     o cleaned up some unused and uninitialized variables
107       (helps when debugging with strict compile options)

111    
112    checkpoint25
113     o updates for OBCs and NH
114     o dramatically reduced memory usage
115     o added "JAM" routines for use on Artic network

117     o added a diagnostic of convective index
118     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
119       (this is was partly for OBCs and NH but also in anticipation of
120        an explicit free-surface option)
121     o initial state input files for U and V
122    
123    checkpoint24

155    
156    checkpoint18
157     o Further changes for optional code generation with
158       CPP - ugh!
