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

85    o adjoint-related modifications
86      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
87      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
88      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
