4      ==============================      ==============================
5    
6    checkpoint53d_post
7    o faulks upgraded: re-generate output.txt that have changed:
8       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
9    o Added Bryan and Lewis, 1979, vertical diffusivity profile
10    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
11    o added Sadourny discretization of Coriolis
12      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
13      - re-enabled use of omega3 (useAbsVorticity)
14    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
15      vector-invariant equations
16      - note: does *NOT* yet use same variable visc. for no-slip BC's.
17    o recoded the lateral boundary conditions for non-hydrostatic w, this time
18      hopefully without new bugs
19      - still to do: biharmonic friction for non-hydrostatic w
20    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
21    o regenerated output for global_ocean_ebm (using -ieee)
22    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
23      of mom_common/
24      - simple re-arrangement of instructions within computing loop
25    checkpoint53d_pre
26    
27    checkpoint53c_post
28    o new version of coupler for AIM+thSIce and Ocean models
29     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
30     - land: change Evaporation of snow
31     - aim with thSIce: fix bug in snow-precip.
32    o changes to calc_gw.F
33     - bug fix for w^2 term near the bottom boundary
34     - (hopefully) improve the lateral slip boundary condtions for use with
35        partial/looped cells
36      - because the bug fix changes two verification experiments anyway (exp5
37        and plume on slope), change the lateral boundary condition from half slip
38        to the value of no_slip_sides
39    o ebm package wasnt quite up to the parallel task. Fixed that.
40    o Adjoint of EBM package + verification
41      * TLM OK
42      * ADM not sufficient accuracy yet (needs further testing)
43    
44    checkpoint53b_post
45    o Commiting new energy balance model to repository
46      * package is pkg/ebm
47      * verif. is verification/global_ocean_ebm
48      * references are in ebm_driver.F
49    C      * X. Wang, P. Stone and J. Marotzke, 1999:
50    C        Global thermohaline circulation. Part I:
51    C        Sensitivity to atmospheric moisture transport.
52    C        J. Climate 12(1), 71-82
53    C      * X. Wang, P. Stone and J. Marotzke, 1999:
54    C        Global thermohaline circulation. Part II:
55    C        Sensitivity with interactive transport.
56    C        J. Climate 12(1), 83-91
57    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
58    C        Destabilization of the thermohaline circulation
59    C        by atmospheric eddy transports.
60    C        J. Climate 7(12), 1870-1882
61    o Will need long integration testing.
62    checkpoint53b_pre
63    
64    o created pkg/mom_common in preparation for variable viscosity code
65    o renamed and split ini_mnc_io
66    o pkg/land: only liquid water can diffuse or run-off
67    o AIM using land: soil wetness availability account for snow
68    o added printMapIncludesZeros to EEPARMS namelist
69    
70    checkpoint53a_post
71    o restore TAMC compatiility for exf_constants.h
72      (no usage of _d in .h)
73    o Additional storing in KPP in an attempt to fix
74      TAMC problem with adjoint of KPP code.
75      (no success...)
76      Identical code works fine with TAF.
77    o Fixed verification/natl_box_adjoint experiments.
78      Initial conditions for Experiments 4 and 5 are now
79      set to "SEAICE_initialHEFF=0", which is more reasonable,
80      and hence gives results closer to that of Experiment 2.
81      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
82    
83    checkpoint53
84    o stable checkpoint with up to date adjoint
85      TLM tests only run for 1st grdchk at the moment. Its unclear if
86      this is a code problem or a problem with resetting code for g_
87      variables that is being autogenerated wrong.
88      Otherwise:
89       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
90       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
91         are both still in chaos following their security messes.
92    
93    checkpoint52n_post
94    o various build (mostly genmake2) changes including:
95      - ability to build/run more easily within Cygwin and MacOS X
96      - more complicated Makefiles with a stronger dependence on Gnu Make
97    o pkg/seaice modifications
98      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
99        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
100        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
101      - changed proxy for geostrophic velocity and updated
102        verification/lab_sea/results/* accordingly
103      - removed ADI dynamic solver from pkg/seaice
104      - replaced all occurrences of 1/CSTICE or 1/CSUICE
105        they caused a segmentation fault under certain circumstances
106      - removed unused field WATR
107    o bug fix in exf-package:
108      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
109         now reflect that.
110    o small fixes in the cal-package:
111      - set reference date to first of January for the 'model'-calendar
112      - failing of cal_CheckDate in cal_FullDate now actually results in a
113        warning
114    o small modifications in exf-package to increase flexibility:
115      - change climtempfreeze from a constant to a runtime parameter that
116        is specified in data.exf_clim (default = -1.9)
117      - introduce runtime parameter windstressmax (default = 2.0) that is
118        specified in data.exf
119    o fix in pkg/thsice:
120      - update Evap (Tsf changes) to be consistent with Latent heat flux
121      - maintain snow precipitation unchanged (even if Tsf >=0).
122     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
123    
124    checkpoint52m_post
125    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
126      this does not change any of the results, because myIter=0 in swfrac always
127      lead to jwtype=2 (the default anyway), but the call makes little sense
128      as a default
129    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
130    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
131      atmospheric model (AIM) to use it ; add a "slab ocean" component.
132    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
133    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
134    o extending useSingleCpuIO option to work with new exch2 I/O format
135      - old-style, missing-tile I/O is still accessible by defining CPP
136        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
137    o monitor package can write to NetCDF files and/or STDOUT
138    o fix re-definition bug in MNC_GRID_INIT_ALL()
139    o doc/api_reference added
140      - a framework for building an API Reference Manual using all
141        the "protex" comments embedded in the code
142      - see pkg/generic_advdiff, pkg/mnc for examples
143  o MNC:  o MNC:
144    - make myThid the last argument for all subroutines    - make myThid the last argument for all subroutines
145    - new default for the grid files: NO halos    - new default for the grid files: NO halos
