Tracers

• tracer.def: tracers

  • Number identifying the advection scheme, possibly different for horizontal (hadv) and vertical advection (vadv)
  • Possible: tracer of tracer, useful for isotopes
  • For more information on available advection schemes: dyn3d_common/infotrac.F90
  • See presentation on dynamics by E. Millour.

Syntax for tracer.def

Syntax for traceur.def

• traceur.def: old file with old format for tracers
• First line: number of tracers
• Then one line per tracer, with a number identifying the advection scheme
