4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
8    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
9    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
10      not mnc -- this mistake was found by JMC and is now corrected
11    
12    checkpoint57g_post
13    o add Adams-Bashforth 3rd Order time stepping:
14      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
15      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
16    checkpoint57g_pre
17    
18    o make lambda[Theta,Salt]ClimRelax spatially varying
19      (default remains spatially uniform constant based on tau)
20    o added new control variables
21      * init. uVel, vVel, etanN
22      * lambda[Theta,Salt]ClimRelax
23    o separate masks used for ctrl_pack/unpack 'from write_grid' output
24      (suggested by G. Forget)
25    
26    checkpoint57f_post
27    o add parameter "baseTime" = model base time = time at iteration zero
28      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
29      account for baseTime shift
30    o move Coriolis arrays from PARAMS.h to GRID.h
31    checkpoint57f_pre
32    
33    o mnc-ifying the seaice package
34    o introduced an alternative length scale calculation for use in the limiting
35      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
36    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
37    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
38      as well as grad(vort3).  Made it compatible with both approximate form
39      for the cubed sphere and full form of these gradients.  Added flag
40      useFullLeith to select between approximate and full form.  
41    o add "d0" in getcon.F to reduce differences between compilers/platforms
42      update output.txt of exp. fizhi-gridalt-hs
43    o change port_rand funtion to allow to set the seed.
44    o fix obscure MNC bug involving conversion between reals and integers
45      - it caused no problems with certain (eg. gcc, ifc) compilers but the
46        new version is now more standards-compliant
47    o adjoint-related modifications
48      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
49      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
50      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
51    
52    checkpoint57e_post
53    o Adding eddy stress controls a la Ferreira et al.
54    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
55    
56    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
57      update output.txt of exp. fizhi-gridalt-hs
58    o add more "Z" dimensions and associated coordinate vars to MNC
59    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
60    o parameter calendarDumps: when set, approximate months (30-31 days) and years
61      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
62      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
63      months and years.  Requires pkg/cal.
64    o diagnostics: add pickup functionality
65      - off by default for backwards compatibility
66      - current version only uses MDSIO -- MNC will be added
67    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
68    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
69    
70    checkpoint57d_post
71    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
72    o modify verification/ideal_2D_oce so that it tests the creation of mnc
73      output from the diagnostics package
74    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
75    o make genmake2 more portable by using ".$FS" instead of ".f" for more
76      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
77    o add coordinate variables to the MNC output from the diagnostics package
78    o change MNC-flags default value: true when useMNC=TRUE
79    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
80      the ability (off by default) to read the grid information using MNC
81    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
82    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
83    o do snap-shot diagnostics at the middle of the time-interval (instead of
84      at the end).
85    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
86      new test for AIM with thSIce + slab-ocean
87    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
88    o move state variable diagnostics to the beginning of the time step ;
89      (note: still needs some work specially for snap-shot diagnostics)
90      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
91    
92    checkpoint57c_post
93    o Change testing option (-ieee) to get closer agreement between g77 & ifort
94    o generate new output.txt files on faulks with g77 & the new -ieee option
95    checkpoint57c_pre
96    
97    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
98      update output.txt of exp. global_ocean.90x40x15
99    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
100      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
101  o add saltFlux(+File) forcing capability with periodicExternalForcing  o add saltFlux(+File) forcing capability with periodicExternalForcing
102  o allow to use pkg diagnostics for GM-Redi & ThSIce output  o allow to use pkg diagnostics for GM-Redi & ThSIce output
103  o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.  o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
