4      ==============================      ==============================
5    checkpoint40pre2
6    o Updated to latest branch of AJA, JMC
7    o Added gradient check package
8    o Added routines for passive tracer handling
9    o Added carbon sequestration sensitivity experiment
10    
11    checkpoint39
12     o Modifications and fixes to support TAMC
13       (mainly missing or wrong directives)
14     o Corrected common blocks when fooling TAMC to produce adjoint I/O
15       in addummy_in_stepping
16     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
17     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
18     o Included following packages:
19       cal: calendar
20       exf: external forcing
21       ecco: essential routines to control use of cal, exf
22             (NB: this is not the full ECCO environment)
23     o disabled some packages by default in genmake
24    
25    checkpoint38
26     o see notes_c37_adj.txt
27     o corrected wrong layer index in external_forcing_t
28     o replaced the_main_loop/forward_step by the_main_loop
29     o removed forceoutput from write_state
30       (replaced criteria for initial/final state)
31     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
32    
33    checkpoint37
34     o mdsio.F routine split and packaged in pkg/mdsio
35       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
36        used unless genmake -disable=mdsio)
37     o allow a more precise surface-geopotential gradient for the atmosphere
38       taking into account the change in space of Alpha (=1/rho) at the surface.
39     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
40       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
41     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
42       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
43       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
44     o Time-Average diagnostics defined as a pseudo package "timeave".
45     o pickup files : old pickup (before c35) did not work with new code (c35
46       and after) unless activating 2 commented lines in initialise-varia.
47     o Non-Hydrostatic pickup file Pb fixed.
48     o bug with Rigid-lid version (since c35) fixed.  
49    
50    checkpoint36
51     o implement Crank-Nickelson barotropic time-stepping
52     o recover Time-Average diagnostics
53     o fix Pb in checkpoint (PR#19)
54     o AIM become a standard package ; clean unused CPP_kees
55    
56    checkpoint35
57     o subtantial rewrite of dynamics.f
58     o allows staggered time-stepping
59     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
60     o added bottom drag (linear + quadratic)
61    
62    checkpoint34
63     o Modified exchange routines for correct reverse simulation.
64     o Added verification output to comply with bug fix in impldiff.F
65       as of c33 (exp2, natl_box).
66     o Corrected store directives in dynamics.F
67     o Corrected array boundaries in impldiff.F
68     o Corrected array dimensions in gmredi.
69       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
70     o Added routine GLOBAL_SUM_INT to global_sum.F
71     o Added mdsio_gl.F for ECCO purposes.
72    
73    checkpoint33
74     o Fixed bug in lower BC in impldiff.F
75     o Fixed confusion about units of forcing arrays in FFIELDS.h
76       namely Fu,Fv,Qnet,Qsw,EmPmR:
77       - Removed verification/natl_box/code/external_fields_scale.F
78         (did not differ from that in model/src)
79       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
80         (see FFIELDS.h for description)
81       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
82         kpp_calc.F and kpp_transport_t.F
83       - Removed model/src/external_fields_scale.F and calls to it
84       - verification/natl_box uses flux data with "atmospheric" sign so
85         a special version of external_fields_load.F is used to
86         change the data as it's read in. This way, the arrays
87         have the right units and signs at all times tha a user could
88         possibly use them.
89     o Corrected genmake to delete a temporary file during configuration
90    
91    checkpoint32
92     o Scaling of forcing fields moved from external_forcing.F to
93       external_fields_scale.F, called directly after loading fields.
94     o Surface relaxation terms added to surface tendency fields in
95       extra subroutine.
96     o impldiff.F changed to avoid storing by TAMC of huge intermediate
97       fields.
98     o Changes in GMRedi to comply with packaging structure.
99     o Modifications and bug fixes in KPP package.
100     o Verification experiment for KPP added (verification/nat_box/)
101    
102    checkpoint31
103     o Packages interface brought in line with defined standard
104       -> new routines packages_...F
105       -> changes in initialise_fixed.F, initialise_varia.F
106       -> enables initialisation interface for ECCO package
107     o Rescaling of external forcing fields immediately after read
108       (removed from external_forcing.F)
109       -> new: surface_fields_scale.F
110       -> affects ini_foorcing.F, external_fields_load.F
111     o Computation of surface tendencies before tendency updates.
112       -> new: external_forcing_surf.F
113     o Change of variable names useGMRedi, useKPP, useECCO
114     o Further changes in dynamics.F, impldiff.F for TAMC
115     o Tested for experiments 0, 2, 4.

136     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
137       included some initialisations required for TAMC.
138     o routine calc_isoslopes: modified sqrt computation to make it
139       differentiable for zero argument.
140     o routines dynamics, impldiff:
141       included store directives and tape key computations required for TAMC.
142     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
143

155     o fixed macros like _ADT to work with both versions of Linux cpp
156     o cleaned up some unused and uninitialized variables
157       (helps when debugging with strict compile options)

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