10.4.3 Extrapolation of ISBA properties

Independent of which scheme which is used for nature, there is an option to extrapolate nature variables for points having a nature fraction in SURFEX but a CANARI land-sea mask as water. The variables are extrapolated from the nearest point having land in CANARI and nature in SURFEX.


Fortran name Fortran type values default value

  • LEXTRAP_NATURE : if T, extrapolation is performed.

The variables extrapolated are:

  • TG1/2/3 (with height adjustment)
  • WG1/2
  • WGI1
  • Snow (SWE/density and albedo)
