5      ==============================      ==============================
6    
7    o move getcon.F from model/src to pkg/fizhi.
8    o pkg/exf: add parameter for extrapolation of temp up to the surface
9       and option to prevent negative evap (in bulk_largeyeager04 only).
10    o Prather Advection scheme: fix tracer conservation for divergent flow
11      (e.g., when using NonLin Free-Surface).
12    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
13    o gmredi (Visbeck-variable-K):
14     - add more parameters to Visbeck-variable-K.
15     - use a 5 points average for dSigmaR in Visbeck-K calculation
16       (more "homogenous": same stencil and same weights as in dSigmaH)
17     - update output of ideal_2D_oce experiment.
18    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
19      (#undef REAL4_IS_SLOW)
20     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
21       coordinate variable
22     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
23       (surface forcing fields), removes some of the functionality
24     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
25     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
26       probably not all: copy _RS surface flux fields to RL field before
27       calling DIAGNOSTICS_FILL
28     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
29       real*4 (CALL EXCH_*_RS) versions.
30     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
31       (generate new output).
32    
33    checkpoint61e
34    o gmredi (Visbeck-variable-K):
35      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
36      - change computation of Visbeck-K where Slope > Smax :        
37        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
38        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
39    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
40      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
41    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
42    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
43      does not become too large (to avoid precision problems in implicit-diffusion
44      solver); update ideal_2D_oce output.
45    o pkg ggl90:
46      - in ggl90_cal.F: compute only one set of visc/diff, used to
47        step forward TKE/T/S/momentum
48      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
49        have Prandlt =1)
50    o gmredi (fm07):
51      - add lower limit on Transition layer thickness + lower limit on 1/lambda
52      - allow to set few more params from data.gmredi
53    o pkg ggl90:
54          - add missing sqrt(2) factor in computation of mixing length
55            scale in ggl90_calc.F
56            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
57    
58    checkpoint61d
59    o adjoint modifs
60      - adapt to new field rhoInSitu
61      - allow to revert from StoreDynVars2D, StoreDynVars3D
62        to individual fields
63        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
64    o store 3-D (in-situ) density in commom block (DYNVARS.h)
65     - save 1 rho computation.
66     - no longer modify T & S inland when using down_slope pkg.
67    o gad_som : allow to switch to SOM advection for T & S without corresponding
68      pickup files (using new S/R: MDS_CHECK4FILE).
69    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
70      (for useSingleCpuIO to work in multi-threaded)
71    o pkg/shelfice:
72     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
73       with SHELFICEtopoFile in data.shelfice
74     - move code for reading ice shelf topography and modifying hFacC into separate
75       subroutines of the shelfice package
76     - separate initialisation of "fixed" and "variable" variables
77     - kTopC is not (yet) replaced by kSurfC, although this is possible
78    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
79    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
80      and rename:
81      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
82      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
83    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
84    
85    checkpoint61c
86    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
87      to add mass source/sink of fluid in the interior (3-D generalisation
88      of oceanic real-fresh water flux).
89    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
90  o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)  o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
91  o new pkg: down_slope  o new pkg: down_slope
92    density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).    density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
