5      ==============================      ==============================
6    
7    checkpoint61f
8    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
9      update results of global_ocean.cs32x15.icedyn test.
10    o move getcon.F from model/src to pkg/fizhi.
11    o pkg/exf: add parameter for extrapolation of temp up to the surface
12       and option to prevent negative evap (in bulk_largeyeager04 only).
13    o Prather Advection scheme: fix tracer conservation for divergent flow
14      (e.g., when using NonLin Free-Surface).
15    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
16    o gmredi (Visbeck-variable-K):
17     - add more parameters to Visbeck-variable-K.
18     - use a 5 points average for dSigmaR in Visbeck-K calculation
19       (more "homogenous": same stencil and same weights as in dSigmaH)
20     - update output of ideal_2D_oce experiment.
21    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
22      (#undef REAL4_IS_SLOW)
23     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
24       coordinate variable
25     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
26       (surface forcing fields), removes some of the functionality
27     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
28     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
29       probably not all: copy _RS surface flux fields to RL field before
30       calling DIAGNOSTICS_FILL
31     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
32       real*4 (CALL EXCH_*_RS) versions.
33     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
34       (generate new output).
35    
36    checkpoint61e
37    o gmredi (Visbeck-variable-K):
38      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
39      - change computation of Visbeck-K where Slope > Smax :        
40        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
41        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
42    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
43      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
44    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
45    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
46      does not become too large (to avoid precision problems in implicit-diffusion
47      solver); update ideal_2D_oce output.
48    o pkg ggl90:
49      - in ggl90_cal.F: compute only one set of visc/diff, used to
50        step forward TKE/T/S/momentum
51      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
52        have Prandlt =1)
53    o gmredi (fm07):
54      - add lower limit on Transition layer thickness + lower limit on 1/lambda
55      - allow to set few more params from data.gmredi
56    o pkg ggl90:
57          - add missing sqrt(2) factor in computation of mixing length
58            scale in ggl90_calc.F
59            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
60    
61    checkpoint61d
62    o adjoint modifs
63      - adapt to new field rhoInSitu
64      - allow to revert from StoreDynVars2D, StoreDynVars3D
65        to individual fields
66        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
67    o store 3-D (in-situ) density in commom block (DYNVARS.h)
68     - save 1 rho computation.
69     - no longer modify T & S inland when using down_slope pkg.
70    o gad_som : allow to switch to SOM advection for T & S without corresponding
71      pickup files (using new S/R: MDS_CHECK4FILE).
72    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
73      (for useSingleCpuIO to work in multi-threaded)
74    o pkg/shelfice:
75     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
76       with SHELFICEtopoFile in data.shelfice
77     - move code for reading ice shelf topography and modifying hFacC into separate
78       subroutines of the shelfice package
79     - separate initialisation of "fixed" and "variable" variables
80     - kTopC is not (yet) replaced by kSurfC, although this is possible
81    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
82    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
83      and rename:
84      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
85      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
86    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
87    
88    checkpoint61c
89    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
90      to add mass source/sink of fluid in the interior (3-D generalisation
91      of oceanic real-fresh water flux).
92    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
93  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)
94  o new pkg: down_slope  o new pkg: down_slope
95    density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).    density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
