4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
8      end-run around the C/Fortran linking horror in eesup/src/timers.F
9    o added pkg/runclock: allows user to terminate run based on wall clock
10    o added non-hydrostatic scaling parameter: nh_am2
11    o pkg/my82: futile attempt to make results compiler-independent by adding
12      some "_d 0", etc. no effect.
13    o for mnc output, fill the 'T' coordinate var with myTime and create a
14      separate 'iter' variable for iteration count
15    o pkg/diagnostics:
16      add new capability: output of Global/Regional & per-level statistics ;
17      tested against monitor output (including land & thSIce) on various exp.
18    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
19    
20    checkpoint57h_done
21      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
22      data.diagnostics, data.gchem, data.ptracers) is done.
23    
24    o pkg/diagnostics: prepare for Global/Regional statistics.
25      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
26    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
27      and rename it: DIFFERENT_MULTIPLE
28    
29    checkpoint57h_post
30    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
31    o pkg/diagnostics: change output frequency, now in seconds (instead
32      of Nb of iterations). This requires to change data.diagnostics.
33    checkpoint57h_pre
34    
35    o in mnc, let the user create the output dir if both mnc_outdir_date
36      and mnc_outdir_num are false
37    o add fflags() to pkg/diagnostics which allows one to specify, on a
38      per-file basis, the file precision [default behavior is unchanged]
39    o added diagnostics to pkg/kpp, including computation of mixed layer
40      depth based on a temperature/density criterion
41    o updated verification/natl_box to test the new pkg/kpp diagnostics
42    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
43    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
44    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
45      not mnc -- this mistake was found by JMC and is now corrected
46    
47    checkpoint57g_post
48    o add Adams-Bashforth 3rd Order time stepping:
49      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
50      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
51    checkpoint57g_pre
52    
53    o make lambda[Theta,Salt]ClimRelax spatially varying
54      (default remains spatially uniform constant based on tau)
55    o added new control variables
56      * init. uVel, vVel, etanN
57      * lambda[Theta,Salt]ClimRelax
58    o separate masks used for ctrl_pack/unpack 'from write_grid' output
59      (suggested by G. Forget)
60    
61    checkpoint57f_post
62    o add parameter "baseTime" = model base time = time at iteration zero
63      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
64      account for baseTime shift
65    o move Coriolis arrays from PARAMS.h to GRID.h
66    checkpoint57f_pre
67    
68    o mnc-ifying the seaice package
69    o introduced an alternative length scale calculation for use in the limiting
70      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
71    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
72    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
73      as well as grad(vort3).  Made it compatible with both approximate form
74      for the cubed sphere and full form of these gradients.  Added flag
75      useFullLeith to select between approximate and full form.  
76    o add "d0" in getcon.F to reduce differences between compilers/platforms
77      update output.txt of exp. fizhi-gridalt-hs
78    o change port_rand funtion to allow to set the seed.
79    o fix obscure MNC bug involving conversion between reals and integers
80      - it caused no problems with certain (eg. gcc, ifc) compilers but the
81        new version is now more standards-compliant
82    o adjoint-related modifications
83      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
84      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
85      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
86    
87    checkpoint57e_post
88    o Adding eddy stress controls a la Ferreira et al.
89    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
90    
91    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
92      update output.txt of exp. fizhi-gridalt-hs
93    o add more "Z" dimensions and associated coordinate vars to MNC
94    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
95    o parameter calendarDumps: when set, approximate months (30-31 days) and years
96      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
97      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
98      months and years.  Requires pkg/cal.
99    o diagnostics: add pickup functionality
100      - off by default for backwards compatibility
101      - current version only uses MDSIO -- MNC will be added
102    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
103    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
104    
105    checkpoint57d_post
106    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
107    o modify verification/ideal_2D_oce so that it tests the creation of mnc
108      output from the diagnostics package
109    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
110    o make genmake2 more portable by using ".$FS" instead of ".f" for more
111      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
112    o add coordinate variables to the MNC output from the diagnostics package
113    o change MNC-flags default value: true when useMNC=TRUE
114    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
115      the ability (off by default) to read the grid information using MNC
116    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
117    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
118    o do snap-shot diagnostics at the middle of the time-interval (instead of
119      at the end).
120    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
121      new test for AIM with thSIce + slab-ocean
122    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
123    o move state variable diagnostics to the beginning of the time step ;
124      (note: still needs some work specially for snap-shot diagnostics)
125      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
126    
127  checkpoint57c_post  checkpoint57c_post
128  o Change testing option (-ieee) to get closer agreement between g77 & ifort  o Change testing option (-ieee) to get closer agreement between g77 & ifort
129  o generate new output.txt files on faulks with g77 & the new -ieee option  o generate new output.txt files on faulks with g77 & the new -ieee option
