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
107    o fix nchklev in tamc.h for global_ocean...
108    o Bringing flow and store directives up-to-date
109    o Really weird thing!
110      call do_the_model_io from the_main_loop with parameters
111      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
112      TAF places a faulty re-call of initialise_varia
113      after cost_final call which should not be there!
114    checkpoint52j_pre
115    
116    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
117      error messages
118    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
119    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
120      debug output
121    o modfied mdsio_writefield.F to handle non-global files under exch2
122    o update AIM Cubed-Sphere exp (aim.5l_cs):
123      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
124    o update AIM Equatorial Channel exp:
125      use standard aim_v23 pkg and change the SST fields to be more realistic.
126    o globalFile now works with exch2
127    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
128      mon_vort3.F to make exch2 friendly with >1 tile per cube face
129    o limit timeave output for hi-res integrations
130    
131    checkpoint52i_post
132    o removed CPP_EEOPTIONS.h from verification/*/code
133    o updated the tiling for global_ocean_pressure
134    checkpoint52i_pre
135    
136    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
137      the old pkg/aim).
138    
139    checkpoint52h_pre
140    o shortened offending lines in exch2_send_rx?.template
141    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
142    o genmake2: add build & execute test for NetCDF code
143    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
144      old grid files, moved CPP_EEMACROS.h to pkg/exch2
145    o added useSingleCPUIO flag to monitor.F and mon_out.F
146    o added temporary hack for sea-ice dynamics on the cube:
147      metric terms are ignored and it is assumed that
148      there is no sea-ice on cube faces 1, 2, 4, and 5.
149    
150    checkpoint52f_post
151    o added exch2 cube routines to pkg/exch2
152    o modified hs94.cs-32x32x5 to use it

154    checkpoint52f_pre
155    
156    checkpoint52e_post
157    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
158      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
159    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
160      to work with implicit vertical advection and AB ;
161    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
162    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
163     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
164    checkpoint52e_pre
165    
166    o fix bug in impldiff when Nr=1 or Nr=2.
167    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
168    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
169    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
170      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
