6.5.10. Namelist NAM_ISBA_SNOWn

CROCUS snow scheme.

Fortran name Fortran type values default value
LSNOWDRIFT logical T
LSNOWDRIFT_SUBLIM logical F
LSNOW_ABS_ZENITH logical F
CSNOWMETAMO character(3) 'B92', 'C13', 'T07', 'F06' 'B92'
CSNOWRAD character(3) 'B92', 'TAR', 'TA1', 'TA2' 'B92'

  • LSNOWDRIFT : logical for snowdrift
  • LSNOWDRIFT_SUBLIM : logical for snowdrift subliation
  • LSNOW_ABS_ZENITH: if True modify solar absorption as a function of solar zenithal angle (physically wrong but better results in polar regions when CSNOWRAD=B92)
  • CSNOWMETAMO: Scheme of snow metamorphism (Crocus)
    • B92: historical version, Brun et al 92
    • C13: Carmagnola et al 2014
    • T07: Taillandier et al 2007
    • F06: Flanner et al 2006
  • CSNOWRAD: radiative transfer scheme in snow (Crocus)
    • B92: historical version, Brun et al 92
    • TAR: TARTES, Libois et al 2013
    • TA1: TARTES with constant impurities
    • TA2: TARTES with constant impurities as function of ageing
