List of Global Cubed-Sphere (CS510) ECCO2 Perturbation Experiments


ECCO2

List of ECCO2 cubed-sphere sensitivity experiments: Ocean Model Parameters.


cube02 : 1992-2002, with sea-ice dynamics, surface salinity relaxation, and lower vertical viscosity and diffusivity. Bathymetry file changed from ver3b_filled to ver5e_filled.

cube03 : 1992-2002, same as cs510.nb.02 but with half the horizontal biharmonic viscosity: 2.4e11 m^4/s.

cube05 : 1992-2003, same as cs510.nb.04 but shortwave radiation and albedo have been adjusted for a more realistic sea-ice extent.

cube06 : 1992-2000, same as cs510.nb.05 but with yet smaller horizontal biharmonic viscosity: 5e10 m^4/s.

cube09 : same as cube 6 but with Leith biharmonic viscosity.

cube26 : same as cube25 with bug-fix to exf_bulkformulae

cube27 : same as cube26 but with viscC4Leith=1, viscC4Leithd=1, useAreaViscLength=.TRUE., SadournyCoriolis=.TRUE., useAbsVorticity=.TRUE.

cube28 : same as cube.26 but with viscC4Leith=1.5, viscC4Leithd=1.5, highOrderVorticity = .TRUE., useAreaViscLength=.TRUE.

cube29 : same as cube28 but with
SEAICE_strength = 2.75e4

cube30 : same as cube29 but with
diffKrT=1.0e-5,
diffKrS=1.0e-5,

cube31 : same as cube28 but data.seaice has following
parameters default values:
SEAICE_drag = 0.002 _d 0
OCEAN_drag = 0.001 _d 0
SEAICE_waterDrag = 5.5 _d 0
SEAICE_strength = 2.75 _d +04

cube33 : 1992-2002 same as cube31 but with
Ricr = 0.3

cube34 : 1992-2002 same as cube31 but with
tauSaltClimRelax = 7684760.

cube35 : 1992-2002 same as cube31 but with
Riinfty = 0.701
and starting from pickup.0000000216.cube27

cube50 : 1992-2002 same as cube49 but with SEAICEadvSnow=.true. and with more realistic initial sea-ice conditions as in cube48

cube51 : 1992-2002 same as cube50 but with bottomDragQuadratic = 0.0012 (but data.kpp is that of cube47)

cube52 : 1992-2002 same as cube50 but with exf_albedo = 0.16

cube53 : 1992-2002 same as cube50 but with exf_scal_BulkCdn = 0.9

cube64 : same as cube55 but with new ERA40_full_resolution (320x160) forcing from /skylla/data1/data/era40/era40_fullres

cube65 : same as cube64 but with diffKr as function of (y,z) instead of const. Bryan and Lewis 1979 vertical diffusivity parameters with latitudinal dependence:
   #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h
   diffKrFile = 'DIFFKR_2_20_1_lat6070', in data

cube68 : same as cube65 but with blending spfh2m field (cube49)

cube70 : same as cube66 but with GM_background_K=150, GM_Kmin_horiz=50 Bug: PHCT is in-situ rather than potential temperature THETA output was converted back to potential after integration but expected to impact regions of deep convection

cube71 : same as cube66 but with useGMRedi=.FALSE. hydrogThetaFile='PHC_THETA_JAN_510x6x510x50.bin'

cube72 : same as cube70 but with useGMRedi=.TRUE. GM_background_K=100, GM_Kmin_horiz=98, GM_taper_scheme='ldd97'
