4      ==============================      ==============================
5    
6    checkpoint37
7     o mdsio.F routine split and packaged in pkg/mdsio
8       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
9        used unless genmake -disable=mdsio)
10     o allow a more precise surface-geopotential gradient for the atmosphere
11       taking into account the change in space of Alpha (=1/rho) at the surface.
12     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
13       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
14     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
15       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
16       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
17     o Time-Average diagnostics defined as a pseudo package "timeave".
18     o pickup files : old pickup (before c35) did not work with new code (c35
19       and after) unless activating 2 commented lines in initialise-varia.
20     o Non-Hydrostatic pickup file Pb fixed.
21     o bug with Rigid-lid version (since c35) fixed.  
22    
23    checkpoint36
24     o implement Crank-Nickelson barotropic time-stepping
25     o recover Time-Average diagnostics
26     o fix Pb in checkpoint (PR#19)
27     o AIM become a standard package ; clean unused CPP_kees
28    
29    checkpoint35
30     o subtantial rewrite of dynamics.f
31     o allows staggered time-stepping
32     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
33     o added bottom drag (linear + quadratic)
34    
35    checkpoint34
36     o Modified exchange routines for correct reverse simulation.
37     o Added verification output to comply with bug fix in impldiff.F
38       as of c33 (exp2, natl_box).
39     o Corrected store directives in dynamics.F
40     o Corrected array boundaries in impldiff.F
41     o Corrected array dimensions in gmredi.
42       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
43     o Added routine GLOBAL_SUM_INT to global_sum.F
44     o Added mdsio_gl.F for ECCO purposes.
45    
46    checkpoint33
47     o Fixed bug in lower BC in impldiff.F
48     o Fixed confusion about units of forcing arrays in FFIELDS.h
49       namely Fu,Fv,Qnet,Qsw,EmPmR:
50       - Removed verification/natl_box/code/external_fields_scale.F
51         (did not differ from that in model/src)
52       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
53         (see FFIELDS.h for description)
54       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
55         kpp_calc.F and kpp_transport_t.F
56       - Removed model/src/external_fields_scale.F and calls to it
57       - verification/natl_box uses flux data with "atmospheric" sign so
58         a special version of external_fields_load.F is used to
59         change the data as it's read in. This way, the arrays
60         have the right units and signs at all times tha a user could
61         possibly use them.
62     o Corrected genmake to delete a temporary file during configuration
63    
64    checkpoint32
65     o Scaling of forcing fields moved from external_forcing.F to
66       external_fields_scale.F, called directly after loading fields.
67     o Surface relaxation terms added to surface tendency fields in
68       extra subroutine.
69     o impldiff.F changed to avoid storing by TAMC of huge intermediate
70       fields.
71     o Changes in GMRedi to comply with packaging structure.
72     o Modifications and bug fixes in KPP package.
73     o Verification experiment for KPP added (verification/nat_box/)
74    
75    checkpoint31
76     o Packages interface brought in line with defined standard
77       -> new routines packages_...F
78       -> changes in initialise_fixed.F, initialise_varia.F
79       -> enables initialisation interface for ECCO package
80     o Rescaling of external forcing fields immediately after read
81       (removed from external_forcing.F)
82       -> new: surface_fields_scale.F
83       -> affects ini_foorcing.F, external_fields_load.F
84     o Computation of surface tendencies before tendency updates.
85       -> new: external_forcing_surf.F
86     o Change of variable names useGMRedi, useKPP, useECCO
87     o Further changes in dynamics.F, impldiff.F for TAMC
88     o Tested for experiments 0, 2, 4.
89       - not yet tested for GMRedi.
90       - not yet tested for KPP.

92  checkpoint30  checkpoint30
93   o Updates for OBCs   o Updates for OBCs
94   o New experiment for test OBCs (internal_wave)   o New experiment for test OBCs (internal_wave)
