5      ==============================      ==============================
6    
7    checkpoint61e
8    o gmredi (Visbeck-variable-K):
9      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
10      - change computation of Visbeck-K where Slope > Smax :        
11        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
12        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
13    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
14      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
15    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
16    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
17      does not become too large (to avoid precision problems in implicit-diffusion
18      solver); update ideal_2D_oce output.
19    o pkg ggl90:
20      - in ggl90_cal.F: compute only one set of visc/diff, used to
21        step forward TKE/T/S/momentum
22      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
23        have Prandlt =1)
24    o gmredi (fm07):
25      - add lower limit on Transition layer thickness + lower limit on 1/lambda
26      - allow to set few more params from data.gmredi
27    o pkg ggl90:
28          - add missing sqrt(2) factor in computation of mixing length
29            scale in ggl90_calc.F
30            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
31    
32    checkpoint61d
33    o adjoint modifs
34      - adapt to new field rhoInSitu
35      - allow to revert from StoreDynVars2D, StoreDynVars3D
36        to individual fields
37        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
38    o store 3-D (in-situ) density in commom block (DYNVARS.h)
39     - save 1 rho computation.
40     - no longer modify T & S inland when using down_slope pkg.
41    o gad_som : allow to switch to SOM advection for T & S without corresponding
42      pickup files (using new S/R: MDS_CHECK4FILE).
43    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
44      (for useSingleCpuIO to work in multi-threaded)
45    o pkg/shelfice:
46     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
47       with SHELFICEtopoFile in data.shelfice
48     - move code for reading ice shelf topography and modifying hFacC into separate
49       subroutines of the shelfice package
50     - separate initialisation of "fixed" and "variable" variables
51     - kTopC is not (yet) replaced by kSurfC, although this is possible
52    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
53    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
54      and rename:
55      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
56      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
57    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
58    
59    checkpoint61c
60    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
61      to add mass source/sink of fluid in the interior (3-D generalisation
62      of oceanic real-fresh water flux).
63    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
64  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)
65  o new pkg: down_slope  o new pkg: down_slope
66    density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).    density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
