4      ==============================      ==============================
5    
6    checkpoint53b_pre
7    
8    o created pkg/mom_common in preparation for variable viscosity code
9    o renamed and split ini_mnc_io
10    o pkg/land: only liquid water can diffuse or run-off
11    o AIM using land: soil wetness availability account for snow
12    o added printMapIncludesZeros to EEPARMS namelist
13    
14    checkpoint53a_post
15    o restore TAMC compatiility for exf_constants.h
16      (no usage of _d in .h)
17    o Additional storing in KPP in an attempt to fix
18      TAMC problem with adjoint of KPP code.
19      (no success...)
20      Identical code works fine with TAF.
21    o Fixed verification/natl_box_adjoint experiments.
22      Initial conditions for Experiments 4 and 5 are now
23      set to "SEAICE_initialHEFF=0", which is more reasonable,
24      and hence gives results closer to that of Experiment 2.
25      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
26    
27    checkpoint53
28    o stable checkpoint with up to date adjoint
29      TLM tests only run for 1st grdchk at the moment. Its unclear if
30      this is a code problem or a problem with resetting code for g_
31      variables that is being autogenerated wrong.
32      Otherwise:
33       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
34       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
35         are both still in chaos following their security messes.
36    
37    checkpoint52n_post
38    o various build (mostly genmake2) changes including:
39      - ability to build/run more easily within Cygwin and MacOS X
40      - more complicated Makefiles with a stronger dependence on Gnu Make
41    o pkg/seaice modifications
42      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
43        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
44        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
45      - changed proxy for geostrophic velocity and updated
46        verification/lab_sea/results/* accordingly
47      - removed ADI dynamic solver from pkg/seaice
48      - replaced all occurrences of 1/CSTICE or 1/CSUICE
49        they caused a segmentation fault under certain circumstances
50      - removed unused field WATR
51    o bug fix in exf-package:
52      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
53         now reflect that.
54    o small fixes in the cal-package:
55      - set reference date to first of January for the 'model'-calendar
56      - failing of cal_CheckDate in cal_FullDate now actually results in a
57        warning
58    o small modifications in exf-package to increase flexibility:
59      - change climtempfreeze from a constant to a runtime parameter that
60        is specified in data.exf_clim (default = -1.9)
61      - introduce runtime parameter windstressmax (default = 2.0) that is
62        specified in data.exf
63    o fix in pkg/thsice:
64      - update Evap (Tsf changes) to be consistent with Latent heat flux
65      - maintain snow precipitation unchanged (even if Tsf >=0).
66     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
67    
68    checkpoint52m_post
69    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
70      this does not change any of the results, because myIter=0 in swfrac always
71      lead to jwtype=2 (the default anyway), but the call makes little sense
72      as a default
73    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
74    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
75      atmospheric model (AIM) to use it ; add a "slab ocean" component.
76    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
77    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
78    o extending useSingleCpuIO option to work with new exch2 I/O format
79      - old-style, missing-tile I/O is still accessible by defining CPP
80        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
81    o monitor package can write to NetCDF files and/or STDOUT
82    o fix re-definition bug in MNC_GRID_INIT_ALL()
83    o doc/api_reference added
84      - a framework for building an API Reference Manual using all
85        the "protex" comments embedded in the code
86      - see pkg/generic_advdiff, pkg/mnc for examples
87    o MNC:
88      - make myThid the last argument for all subroutines
89      - new default for the grid files: NO halos
90      - add useMNC and other run-time flags
91      - separate per-file-group handling of the unlimited dimension
92      - early initialization of MNC w/ flags read at the eeboot stage
93        and lookup tables set in initialize_fixed
94      - write all MNC output to a freshly-created directory
95    o thermodynamics sea-ice (thsice) is now tested with testreport.
96    o test exp. advect_cs: use the standard cs32 grid ; update output.
97    o Added functionality to grdchk:
98      pick global i,j,k position (or nearest wet) where to perform check.
99    
100    checkpoint52l_post
101    o new land formulation:
102      a) use ground enthalpy as prognostic variable to ensure exact
103         energy conservation.
104      b) account for water temperature and for latent heat of freezing
105         in all processes (rain, run-off, ground storage)
106      c) compute surface and ground temperature implicitly.
107    o aim_v23 modification for new land model:
108      a) Treat separately land / ocean / sea-ice surface fluxes
109         to allow implicit computation of land & sea-ice surface temp.
110      b) add snow precipitation.
111  checkpoint52l_pre  checkpoint52l_pre
112    
113  o fix problem (when 1 tile is empty) in min/max monitor.  o fix problem (when 1 tile is empty) in min/max monitor.
