4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
8                 fix the singleCpuIO RS version of MDSWRITEFIELD
9       and add a WARNING if using globalFiles=T with multi-processors.
10    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
11      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
12    o tracer advection scheme:
13      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
14       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
15       was not very convenient).
16      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
17       (further tests needed for the implicit DST & Flux-Limiter schemes).
18    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
19      and sRef for convenience, handy, when you want to initialize
20      ptracers in a large domain with a constant non-zero value. Also,
21      untangle ptracers_init.F a little.
22    
23    checkpoint57v_post
24    o change dome exp. to use variable viscosity in side-drag terms.
25    o remove all the files from the cfc_offline test since they are now
26      incorporated into tutorial_cfc_offline which has been producing
27      identical results for a few days of testing
28    o add new parameter: sideDragFactor to enable half-slip-side BC
29      and change side-drag S/R to use viscosity from mom_calc_visc
30      (can switch back by setting sideDragFactor=0.); affects results at
31      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
32       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
33    o vorticity & strain are now computed without masking, to account for
34      no-slip-side BC in variable viscosity calculation ; mask is applied
35      anyway later on, before computing advection/coriolis terms.
36    o modify exp4 to test new obcs support for reading from external files
37      and for passive tracers
38    o fix behavior of ptracers_monitor when monitor output is written to a
39      netcdf-file; still not independent of monitor.F (writes in the same
40      file).
41    o change default value of tRef (put a uniform, meaningful value for ocean
42      & atmos) and initialize sRef (was missing, as Martin mentioned).
43    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
44      to be proportional to enstrophy dissipation length.  Thus,
45       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
46      This is now consistent with Smagorinsky and with the manual.
47    
48    checkpoint57u_post
49    o OBCS and PTRACERS: add open boundary support for passive tracers
50      - either use homogenous (pseudo) v.Neumann conditions or prescribe
51        OB-values from file; this is not different from the way theta and salinity
52        are treated
53      - however, Orlanski-radiation conditions are not supported, and the model
54        will stop if you use pTracers and Orlanski at the same time.
55      - beefed up the rountine obcs_external_fields_load: now only those open
56        boundary values are overwritten with values from files for which there
57        are really files, otherwise the OB-fields remain untouched. This makes
58        it possible to use different OBs at different ends of the domain (as
59        with EXF)
60    o reduce number of exch calls in shap_filt (s2).
61    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
62      truncation level) 4/5 MLAdjust test results (11&12 digits match).
63    
64    checkpoint57t_post
65    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
66    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
67      same truncation, independent of the face number: affects affects several
68      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
69    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
70      note that biharmonic viscosity + no-slip was not tested in any experiment.
71    o fix bug in non-linear free-surf side-drag ; generate new output for
72      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
73    o make mnc honor the writeBinaryPrec flag for most kinds of output
74    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
75    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
76      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
77    o add brackets in multi-terms sum to get same truncation, independent of
78      the face number (manage to get exactly same value of gU,gV at the cs-edge)
79      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
80    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
81      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
82      a maximum grid-scale Reynolds number.  Also, changes all length calculations
83      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
84      Suggested values of viscosity parameters found in mom_calc_visc.
85      Many new viscosity diagnostics available.
86    
87    checkpoint57s_post
88    o Add clearing-house for viscosity calculations, mom_calc_visc and
89      correct numerous bugs in LeithD and Smagorinsky discretizations.  
90      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
91      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
92      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
93      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
94      The Strain-Tension form is now called with useStrainTensonVisc=.true.
95      ViscAhStrain and viscAhTension are now retired.
96    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
97  o In response to JMC's bug report, genmake2 now ignores any soft-links  o In response to JMC's bug report, genmake2 now ignores any soft-links
