4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
8     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
9    
10  eckpoint57e_pre  checkpoint57i_post
11    o Diagnostics package was changed: diagnostic allocation is now deactivated
12      by setting an empty file name in the namelist (used to be by setting 0 frequency)
13    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
14      add 1rst Order upwind vertical Shear.
15    o add a quick fix for A/B checkpointing in OFFLINE mode
16    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
17      end-run around the C/Fortran linking horror in eesup/src/timers.F
18    o added pkg/runclock: allows user to terminate run based on wall clock
19    o added non-hydrostatic scaling parameter: nh_am2
20    o pkg/my82: futile attempt to make results compiler-independent by adding
21      some "_d 0", etc. no effect.
22    o for mnc output, fill the 'T' coordinate var with myTime and create a
23      separate 'iter' variable for iteration count
24    o pkg/diagnostics:
25      add new capability: output of Global/Regional & per-level statistics ;
26      tested against monitor output (including land & thSIce) on various exp.
27    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
28    
29    checkpoint57h_done
30      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
31      data.diagnostics, data.gchem, data.ptracers) is done.
32    
33    o pkg/diagnostics: prepare for Global/Regional statistics.
34      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
35    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
36      and rename it: DIFFERENT_MULTIPLE
37    
38    checkpoint57h_post
39    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
40    o pkg/diagnostics: change output frequency, now in seconds (instead
41      of Nb of iterations). This requires to change data.diagnostics.
42    checkpoint57h_pre
43    
44    o in mnc, let the user create the output dir if both mnc_outdir_date
45      and mnc_outdir_num are false
46    o add fflags() to pkg/diagnostics which allows one to specify, on a
47      per-file basis, the file precision [default behavior is unchanged]
48    o added diagnostics to pkg/kpp, including computation of mixed layer
49      depth based on a temperature/density criterion
50    o updated verification/natl_box to test the new pkg/kpp diagnostics
51    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
52    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
53    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
54      not mnc -- this mistake was found by JMC and is now corrected
55    
56    checkpoint57g_post
57    o add Adams-Bashforth 3rd Order time stepping:
58      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
59      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
60    checkpoint57g_pre
61    
62    o make lambda[Theta,Salt]ClimRelax spatially varying
63      (default remains spatially uniform constant based on tau)
64    o added new control variables
65      * init. uVel, vVel, etanN
66      * lambda[Theta,Salt]ClimRelax
67    o separate masks used for ctrl_pack/unpack 'from write_grid' output
68      (suggested by G. Forget)
69    
70    checkpoint57f_post
71    o add parameter "baseTime" = model base time = time at iteration zero
72      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
73      account for baseTime shift
74    o move Coriolis arrays from PARAMS.h to GRID.h
75    checkpoint57f_pre
76    
77    o mnc-ifying the seaice package
78    o introduced an alternative length scale calculation for use in the limiting
79      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
80    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
81    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
82      as well as grad(vort3).  Made it compatible with both approximate form
83      for the cubed sphere and full form of these gradients.  Added flag
84      useFullLeith to select between approximate and full form.  
85    o add "d0" in getcon.F to reduce differences between compilers/platforms
86      update output.txt of exp. fizhi-gridalt-hs
87    o change port_rand funtion to allow to set the seed.
88    o fix obscure MNC bug involving conversion between reals and integers
89      - it caused no problems with certain (eg. gcc, ifc) compilers but the
90        new version is now more standards-compliant
91    o adjoint-related modifications
92      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
93      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
94      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
95    
96    checkpoint57e_post
97    o Adding eddy stress controls a la Ferreira et al.
98    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
99    
100  o fizhi pkg: fix AtoC and CtoA when called with same input & output array  o fizhi pkg: fix AtoC and CtoA when called with same input & output array
101    update output.txt of exp. fizhi-gridalt-hs    update output.txt of exp. fizhi-gridalt-hs
