3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint57f_pre
7    
8    o mnc-ifying the seaice package
9    o introduced an alternative length scale calculation for use in the limiting
10      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
11    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
12    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
13      as well as grad(vort3).  Made it compatible with both approximate form
14      for the cubed sphere and full form of these gradients.  Added flag
15      useFullLeith to select between approximate and full form.  
16    o add "d0" in getcon.F to reduce differences between compilers/platforms
17      update output.txt of exp. fizhi-gridalt-hs
18    o change port_rand funtion to allow to set the seed.
19    o fix obscure MNC bug involving conversion between reals and integers
20      - it caused no problems with certain (eg. gcc, ifc) compilers but the
21        new version is now more standards-compliant
22    o adjoint-related modifications
23      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
24      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
25      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
26    
27    checkpoint57e_post
28    o Adding eddy stress controls a la Ferreira et al.
29    checkpoint57e_pre
30    
31    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
32      update output.txt of exp. fizhi-gridalt-hs
33    o add more "Z" dimensions and associated coordinate vars to MNC
34    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
35    o parameter calendarDumps: when set, approximate months (30-31 days) and years
36      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
37      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
38      months and years.  Requires pkg/cal.
39    o diagnostics: add pickup functionality
40      - off by default for backwards compatibility
41      - current version only uses MDSIO -- MNC will be added
42    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
43    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
44    
45    checkpoint57d_post
46    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
47    o modify verification/ideal_2D_oce so that it tests the creation of mnc
48      output from the diagnostics package
49    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
50    o make genmake2 more portable by using ".$FS" instead of ".f" for more
51      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
52    o add coordinate variables to the MNC output from the diagnostics package
53    o change MNC-flags default value: true when useMNC=TRUE
54    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
55      the ability (off by default) to read the grid information using MNC
56    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
57    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
58    o do snap-shot diagnostics at the middle of the time-interval (instead of
59      at the end).
60    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
61      new test for AIM with thSIce + slab-ocean
62    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
63    o move state variable diagnostics to the beginning of the time step ;
64      (note: still needs some work specially for snap-shot diagnostics)
65      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
66    
67    checkpoint57c_post
68    o Change testing option (-ieee) to get closer agreement between g77 & ifort
69    o generate new output.txt files on faulks with g77 & the new -ieee option
70    checkpoint57c_pre
71    
72    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
73      update output.txt of exp. global_ocean.90x40x15
74    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
75      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
76    o add saltFlux(+File) forcing capability with periodicExternalForcing
77    o allow to use pkg diagnostics for GM-Redi & ThSIce output
78    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
79    o improvements for the MNC output from DIAGNOSTICS:
80      - correct handling of the unlimitied dimension
81      - all dims now have associated coordinate variables
82      - variables located at U, V, and Corner ("Z") points are now written
83        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
84        *all* data points are output
85    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
86    o added pkg/seaice/seaice_monitor.F
87  o mdsio_readfield.F can now read files visible only to master MPI process.  o mdsio_readfield.F can now read files visible only to master MPI process.
88  o pkg/seaice: some test code for ice-modified ocean stress  o pkg/seaice: some test code for ice-modified ocean stress
89  o exf_getffields interpolation defaults to bilinear for all scalar forcing  o exf_getffields interpolation defaults to bilinear for all scalar forcing
90    fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,    fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
91    spurious negative numbers for precipitation and humidity.  Will cause    spurious negative numbers for precipitation and humidity.  Will cause
92    some small numerical differences for integrations using pkg/exf/exf_interp.F.    some small numerical differences for integrations using pkg/exf/exf_interp.F.
93    o pkg/ctrl/
94      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
95        May be enabled via doPackDiag
96      *  introduce z-scaling of
97         + gradient (doZscalePack) and
98         + control (doZscaleUnpack)
99    o pkg/mdsio/
100      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
101      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
102    
103  checkpoint57b_post  checkpoint57b_post
104  o simplify options in diagnostics_fill arguments (remove weird combinations)  o simplify options in diagnostics_fill arguments (remove weird combinations)
