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