NAM_DUST

This namelist is use to activate explicit aerosol dusts. It is not necessary to use chemistry to activate dusts but it is recommended to activate on-line dust emissions (see SURFEX namelists). Radiative direct effects are automatically deduced from an interpolation table of SHDOM radiative code (Mie).

  • LDUST : flag to activate passive dust aerosol.

  • LVARSIG : flag to activate variable standard deviation for each dust mode.

  • LSEDIMDUST : flag to activate dust sedimentation.

  • NMODE_DST : number of lognormal dust modes (maximum of 3 modes).

  • LRGFIX_DST : flag to use only 1 moment for each dust mode (LRGFIX_DST=’TRUE’ associated to LVARSIG=’FALSE)

  • LDEPOS_DST : flag to activate wet dust deposition

  • LPASPOL_DST: emit dust aerosols instead of passive scalar

  • LSED2MOM_DST: flag to activate multimoment sedimentation
