4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
8      update results of global_ocean.cs32x15.icedyn test.
9    o move getcon.F from model/src to pkg/fizhi.
10    o pkg/exf: add parameter for extrapolation of temp up to the surface
11       and option to prevent negative evap (in bulk_largeyeager04 only).
12    o Prather Advection scheme: fix tracer conservation for divergent flow
13      (e.g., when using NonLin Free-Surface).
14    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
15    o gmredi (Visbeck-variable-K):
16     - add more parameters to Visbeck-variable-K.
17     - use a 5 points average for dSigmaR in Visbeck-K calculation
18       (more "homogenous": same stencil and same weights as in dSigmaH)
19     - update output of ideal_2D_oce experiment.
20    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
21      (#undef REAL4_IS_SLOW)
22     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
23       coordinate variable
24     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
25       (surface forcing fields), removes some of the functionality
26     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
27     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
28       probably not all: copy _RS surface flux fields to RL field before
29       calling DIAGNOSTICS_FILL
30     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
31       real*4 (CALL EXCH_*_RS) versions.
32     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
33       (generate new output).
34    
35    checkpoint61e
36    o gmredi (Visbeck-variable-K):
37      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
38      - change computation of Visbeck-K where Slope > Smax :        
39        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
40        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
41    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
42      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
43    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
44    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
45      does not become too large (to avoid precision problems in implicit-diffusion
46      solver); update ideal_2D_oce output.
47    o pkg ggl90:
48      - in ggl90_cal.F: compute only one set of visc/diff, used to
49        step forward TKE/T/S/momentum
50      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
51        have Prandlt =1)
52    o gmredi (fm07):
53      - add lower limit on Transition layer thickness + lower limit on 1/lambda
54      - allow to set few more params from data.gmredi
55    o pkg ggl90:
56          - add missing sqrt(2) factor in computation of mixing length
57            scale in ggl90_calc.F
58            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
59    
60    checkpoint61d
61    o adjoint modifs
62      - adapt to new field rhoInSitu
63      - allow to revert from StoreDynVars2D, StoreDynVars3D
64        to individual fields
65        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
66    o store 3-D (in-situ) density in commom block (DYNVARS.h)
67     - save 1 rho computation.
68     - no longer modify T & S inland when using down_slope pkg.
69    o gad_som : allow to switch to SOM advection for T & S without corresponding
70      pickup files (using new S/R: MDS_CHECK4FILE).
71    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
72      (for useSingleCpuIO to work in multi-threaded)
73    o pkg/shelfice:
74     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
75       with SHELFICEtopoFile in data.shelfice
76     - move code for reading ice shelf topography and modifying hFacC into separate
77       subroutines of the shelfice package
78     - separate initialisation of "fixed" and "variable" variables
79     - kTopC is not (yet) replaced by kSurfC, although this is possible
80    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
81    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
82      and rename:
83      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
84      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
85    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
86    
87    checkpoint61c
88  o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"  o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
89    to add mass source/sink of fluid in the interior (3-D generalisation    to add mass source/sink of fluid in the interior (3-D generalisation
90    of oceanic real-fresh water flux).    of oceanic real-fresh water flux).
