3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o pkg/seaice modifications
7      - changed proxy for geostrophic velocity and updated
8        verification/lab_sea/results/* accordingly
9      - removed ADI dynamic solver from pkg/seaice
10      - replaced all occurrences of 1/CSTICE or 1/CSUICE
11        they caused a segmentation fault under certain circumstances
12      - removed unused field WATR
13    o bug fix in exf-package:
14      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
15         now reflect that.
16    o small fixes in the cal-package:
17      - set reference date to first of January for the 'model'-calendar
18      - failing of cal_CheckDate in cal_FullDate now actually results in a
19        warning
20    o small modifications in exf-package to increase flexibility:
21      - change climtempfreeze from a constant to a runtime parameter that
22        is specified in data.exf_clim (default = -1.9)
23      - introduce runtime parameter windstressmax (default = 2.0) that is
24        specified in data.exf
25    o fix in pkg/thsice:
26      - update Evap (Tsf changes) to be consistent with Latent heat flux
27      - maintain snow precipitation unchanged (even if Tsf >=0).
28     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
29    
30    checkpoint52m_post
31    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
32      this does not change any of the results, because myIter=0 in swfrac always
33      lead to jwtype=2 (the default anyway), but the call makes little sense
34      as a default
35    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
36    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
37      atmospheric model (AIM) to use it ; add a "slab ocean" component.
38    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
39    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
40    o extending useSingleCpuIO option to work with new exch2 I/O format
41      - old-style, missing-tile I/O is still accessible by defining CPP
42        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
43    o monitor package can write to NetCDF files and/or STDOUT
44    o fix re-definition bug in MNC_GRID_INIT_ALL()
45    o doc/api_reference added
46      - a framework for building an API Reference Manual using all
47        the "protex" comments embedded in the code
48      - see pkg/generic_advdiff, pkg/mnc for examples
49    o MNC:
50      - make myThid the last argument for all subroutines
51      - new default for the grid files: NO halos
52      - add useMNC and other run-time flags
53      - separate per-file-group handling of the unlimited dimension
54      - early initialization of MNC w/ flags read at the eeboot stage
55        and lookup tables set in initialize_fixed
56      - write all MNC output to a freshly-created directory
57    o thermodynamics sea-ice (thsice) is now tested with testreport.
58    o test exp. advect_cs: use the standard cs32 grid ; update output.
59    o Added functionality to grdchk:
60      pick global i,j,k position (or nearest wet) where to perform check.
61    
62    checkpoint52l_post
63    o new land formulation:
64      a) use ground enthalpy as prognostic variable to ensure exact
65         energy conservation.
66      b) account for water temperature and for latent heat of freezing
67         in all processes (rain, run-off, ground storage)
68      c) compute surface and ground temperature implicitly.
69    o aim_v23 modification for new land model:
70      a) Treat separately land / ocean / sea-ice surface fluxes
71         to allow implicit computation of land & sea-ice surface temp.
72      b) add snow precipitation.
73    checkpoint52l_pre
74    
75    o fix problem (when 1 tile is empty) in min/max monitor.
76    o fix bug in timeAve (u,vZetatave in common block)
77    o no restoring terms under ice for pkg/seaice
78    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
79    o bug fix for pkg/seaice pickups
80    o change MNC call locations and add coordinate attributes
81    o mask vorticity at the corner ; affects global_ocean.cs output
82    o fix ini_curvilinear_grid ; test CS experiments with mpi
83    o aim.5l_cs: modify sea-ice fraction input file ; update output
84    o exf: Adding simple range check routine for exf fields after read
85    
86    checkpoint52k_post
87    o removed top-level directory "diags"
88      - we migrated these functions to pkg/timeave a long time ago
89    o fixed bug introduced in pkg/monitor
90    o accuracy ctrlprec = 32 insuffient for gradient checks using
91      averaged fields (I/O via cost_averages)
92      -> use ctrl.h in active_file*.F to control I/O precision.
93    o paramter list of CALL ADTHE_MAIN_LOOP
94    o added initial do_the_model_io to ecco
95    o set all ...Freq to zero after cost_final
96      taveFreq, dumpFreq, pChkptFreq
97    o MAIN and ECCO differentiability restored
98    
99    checkpoint52j_post
100    o fix nchklev in tamc.h for global_ocean...
101    o Bringing flow and store directives up-to-date
102    o Really weird thing!
103      call do_the_model_io from the_main_loop with parameters
104      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
105      TAF places a faulty re-call of initialise_varia
106      after cost_final call which should not be there!
107    checkpoint52j_pre
108    
109    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
110      error messages
111    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
112    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
113      debug output
114    o modfied mdsio_writefield.F to handle non-global files under exch2
115    o update AIM Cubed-Sphere exp (aim.5l_cs):
116      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
117    o update AIM Equatorial Channel exp:
118      use standard aim_v23 pkg and change the SST fields to be more realistic.
119    o globalFile now works with exch2
120    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
121      mon_vort3.F to make exch2 friendly with >1 tile per cube face
122    o limit timeave output for hi-res integrations
123    
124    checkpoint52i_post
125    o removed CPP_EEOPTIONS.h from verification/*/code
126    o updated the tiling for global_ocean_pressure
127    checkpoint52i_pre
128    
129    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
130      the old pkg/aim).
131    
132    checkpoint52h_pre
133    o shortened offending lines in exch2_send_rx?.template
134    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
135    o genmake2: add build & execute test for NetCDF code
136    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
137      old grid files, moved CPP_EEMACROS.h to pkg/exch2
138    o added useSingleCPUIO flag to monitor.F and mon_out.F
139    o added temporary hack for sea-ice dynamics on the cube:
140      metric terms are ignored and it is assumed that
141      there is no sea-ice on cube faces 1, 2, 4, and 5.
142    
143    checkpoint52f_post
144    o added exch2 cube routines to pkg/exch2
145    o modified hs94.cs-32x32x5 to use it

147    checkpoint52f_pre
148    
149    checkpoint52e_post
150    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
151      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
152    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
153      to work with implicit vertical advection and AB ;
154    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
155    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
156     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
157    checkpoint52e_pre
158    
159    o fix bug in impldiff when Nr=1 or Nr=2.
