4      ==============================      ==============================
5    
6    checkpoint52n_post
7    o various build (mostly genmake2) changes including:
8      - ability to build/run more easily within Cygwin and MacOS X
9      - more complicated Makefiles with a stronger dependence on Gnu Make
10    o pkg/seaice modifications
11      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
12        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
13        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
14      - changed proxy for geostrophic velocity and updated
15        verification/lab_sea/results/* accordingly
16      - removed ADI dynamic solver from pkg/seaice
17      - replaced all occurrences of 1/CSTICE or 1/CSUICE
18        they caused a segmentation fault under certain circumstances
19      - removed unused field WATR
20    o bug fix in exf-package:
21      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
22         now reflect that.
23    o small fixes in the cal-package:
24      - set reference date to first of January for the 'model'-calendar
25      - failing of cal_CheckDate in cal_FullDate now actually results in a
26        warning
27    o small modifications in exf-package to increase flexibility:
28      - change climtempfreeze from a constant to a runtime parameter that
29        is specified in data.exf_clim (default = -1.9)
30      - introduce runtime parameter windstressmax (default = 2.0) that is
31        specified in data.exf
32    o fix in pkg/thsice:
33      - update Evap (Tsf changes) to be consistent with Latent heat flux
34      - maintain snow precipitation unchanged (even if Tsf >=0).
35     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
36    
37    checkpoint52m_post
38    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
39      this does not change any of the results, because myIter=0 in swfrac always
40      lead to jwtype=2 (the default anyway), but the call makes little sense
41      as a default
42    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
43    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
44      atmospheric model (AIM) to use it ; add a "slab ocean" component.
45    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
46    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
47    o extending useSingleCpuIO option to work with new exch2 I/O format
48      - old-style, missing-tile I/O is still accessible by defining CPP
49        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
50    o monitor package can write to NetCDF files and/or STDOUT
51    o fix re-definition bug in MNC_GRID_INIT_ALL()
52    o doc/api_reference added
53      - a framework for building an API Reference Manual using all
54        the "protex" comments embedded in the code
55      - see pkg/generic_advdiff, pkg/mnc for examples
56    o MNC:
57      - make myThid the last argument for all subroutines
58      - new default for the grid files: NO halos
59      - add useMNC and other run-time flags
60      - separate per-file-group handling of the unlimited dimension
61      - early initialization of MNC w/ flags read at the eeboot stage
62        and lookup tables set in initialize_fixed
63      - write all MNC output to a freshly-created directory
64    o thermodynamics sea-ice (thsice) is now tested with testreport.
65    o test exp. advect_cs: use the standard cs32 grid ; update output.
66    o Added functionality to grdchk:
67      pick global i,j,k position (or nearest wet) where to perform check.
68    
69    checkpoint52l_post
70    o new land formulation:
71      a) use ground enthalpy as prognostic variable to ensure exact
72         energy conservation.
73      b) account for water temperature and for latent heat of freezing
74         in all processes (rain, run-off, ground storage)
75      c) compute surface and ground temperature implicitly.
76    o aim_v23 modification for new land model:
77      a) Treat separately land / ocean / sea-ice surface fluxes
78         to allow implicit computation of land & sea-ice surface temp.
79      b) add snow precipitation.
80    checkpoint52l_pre
81    
82    o fix problem (when 1 tile is empty) in min/max monitor.
83    o fix bug in timeAve (u,vZetatave in common block)
84    o no restoring terms under ice for pkg/seaice
85    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
86    o bug fix for pkg/seaice pickups
87    o change MNC call locations and add coordinate attributes
88    o mask vorticity at the corner ; affects global_ocean.cs output
89    o fix ini_curvilinear_grid ; test CS experiments with mpi
90    o aim.5l_cs: modify sea-ice fraction input file ; update output
91    o exf: Adding simple range check routine for exf fields after read
92    
93    checkpoint52k_post
94    o removed top-level directory "diags"
95      - we migrated these functions to pkg/timeave a long time ago
96    o fixed bug introduced in pkg/monitor
97    o accuracy ctrlprec = 32 insuffient for gradient checks using
98      averaged fields (I/O via cost_averages)
99      -> use ctrl.h in active_file*.F to control I/O precision.
100    o paramter list of CALL ADTHE_MAIN_LOOP
101    o added initial do_the_model_io to ecco
102    o set all ...Freq to zero after cost_final
103      taveFreq, dumpFreq, pChkptFreq
104    o MAIN and ECCO differentiability restored
105    
106  checkpoint52j_post  checkpoint52j_post
107  o fix nchklev in tamc.h for global_ocean...  o fix nchklev in tamc.h for global_ocean...
108  o Bringing flow and store directives up-to-date  o Bringing flow and store directives up-to-date
