4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
8      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
9    o tracer advection scheme:
10      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
11       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
12       was not very convenient).
13      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
14       (further tests needed for the implicit DST & Flux-Limiter schemes).
15    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
16      and sRef for convenience, handy, when you want to initialize
17      ptracers in a large domain with a constant non-zero value. Also,
18      untangle ptracers_init.F a little.
19    
20    checkpoint57v_post
21    o change dome exp. to use variable viscosity in side-drag terms.
22    o remove all the files from the cfc_offline test since they are now
23      incorporated into tutorial_cfc_offline which has been producing
24      identical results for a few days of testing
25    o add new parameter: sideDragFactor to enable half-slip-side BC
26      and change side-drag S/R to use viscosity from mom_calc_visc
27      (can switch back by setting sideDragFactor=0.); affects results at
28      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
29       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
30    o vorticity & strain are now computed without masking, to account for
31      no-slip-side BC in variable viscosity calculation ; mask is applied
32      anyway later on, before computing advection/coriolis terms.
33    o modify exp4 to test new obcs support for reading from external files
34      and for passive tracers
35    o fix behavior of ptracers_monitor when monitor output is written to a
36      netcdf-file; still not independent of monitor.F (writes in the same
37      file).
38    o change default value of tRef (put a uniform, meaningful value for ocean
39      & atmos) and initialize sRef (was missing, as Martin mentioned).
40    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
41      to be proportional to enstrophy dissipation length.  Thus,
42       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
43      This is now consistent with Smagorinsky and with the manual.
44    
45    checkpoint57u_post
46    o OBCS and PTRACERS: add open boundary support for passive tracers
47      - either use homogenous (pseudo) v.Neumann conditions or prescribe
48        OB-values from file; this is not different from the way theta and salinity
49        are treated
50      - however, Orlanski-radiation conditions are not supported, and the model
51        will stop if you use pTracers and Orlanski at the same time.
52      - beefed up the rountine obcs_external_fields_load: now only those open
53        boundary values are overwritten with values from files for which there
54        are really files, otherwise the OB-fields remain untouched. This makes
55        it possible to use different OBs at different ends of the domain (as
56        with EXF)
57    o reduce number of exch calls in shap_filt (s2).
58    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
59      truncation level) 4/5 MLAdjust test results (11&12 digits match).
60    
61    checkpoint57t_post
62    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
63    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
64      same truncation, independent of the face number: affects affects several
65      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
66    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
67      note that biharmonic viscosity + no-slip was not tested in any experiment.
68    o fix bug in non-linear free-surf side-drag ; generate new output for
69      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
70    o make mnc honor the writeBinaryPrec flag for most kinds of output
71    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
72    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
73      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
74    o add brackets in multi-terms sum to get same truncation, independent of
75      the face number (manage to get exactly same value of gU,gV at the cs-edge)
76      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
77    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
78      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
79      a maximum grid-scale Reynolds number.  Also, changes all length calculations
80      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
81      Suggested values of viscosity parameters found in mom_calc_visc.
82      Many new viscosity diagnostics available.
83    
84    checkpoint57s_post
85    o Add clearing-house for viscosity calculations, mom_calc_visc and
86      correct numerous bugs in LeithD and Smagorinsky discretizations.  
87      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
88      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
89      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
90      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
91      The Strain-Tension form is now called with useStrainTensonVisc=.true.
92      ViscAhStrain and viscAhTension are now retired.
93    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
94    o In response to JMC's bug report, genmake2 now ignores any soft-links
95      that it finds in the *current* directory when searching for files.
96      Soft-links found in any other source directories will still work as
97      they did before.
98    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
99      a C routine to unlimit the stack size
100    o mnc-ify pkg/aim snapshot vars
101    o mnc-ify pkg/land as requested by Daniel
102    o various changes to mnc including:
103      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
104      - output can now be grouped so that all files within a group
105          change the ITER portion of their names in lock-step together
106      - can now read ("global") PER-FACE (in addition to PER-TILE) files
107          and works with both EXCH1 and EXCH2 (but needs more testing)
108      - writing works for all verification test cases w/ g77 on Linux
109    
110    checkpoint57r_post
111    o make MNC variable initialization happen earlier
112    o add diagnostics for (almost) each term of the momentum Eq.
113    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
114    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
115    o remove MINIMAL_TAVE_OUTPUT option ;
116      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
117    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
118      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
119    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
120    o add time-dependent SST, SSS control
121    o cost terms in ecco/ modularized (new cost_generic.F)
122    o cost_averages routines are modularized (new cost_averagesgeneric.F)
123    o new infrastructure for seaice model vs. obs misfits in seaice/
124      * driver from the_main_loop.F is seaice_cost_driver.F
125      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
126      * gradient check in Exp. 6a of natl_box_adjoint/
127    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
128      (see README file)
129    
130  checkpoint57q_post  checkpoint57q_post
131  o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)  o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
132  o fix annoying months-old bug in mnc/mdsio output for seaice pkg  o fix annoying months-old bug in mnc/mdsio output for seaice pkg
