4.4.3.1. ISBA scheme: NAM_DATA_ISBA

Over natural areas, all surface parameters for each vegtype at a given frequency have to be specified by the user in namelist NAM_DATA_ISBA.

If LECOCLIMAP = T (NAM_FRAC), only part of the surface parameters for each vegtype can be given in NAM_DATA_ISBA. They are then completed by ECOCLIMAP data.

If only data for some of the 19 vegtypes are given, other vegtypes are filled with the values of the first given vegtype placed before in the list of 19.

The order of the vegtypes is the following:

  • 1: no vegetation (smooth) - NO
  • 2: no vegetation (rocks) - ROCK
  • 3: permanent snow and ice - SNOW
  • 4: temperate broadleaf cold-deciduous summergreen - TEBD
  • 5: boreal needleleaf evergreen - BONE
  • 6: tropical broadleaf evergreen - EVER
  • 7: C3 cultures types - C3
  • 8: C4 cultures types - C4
  • 9: irrigated crops - IRR
  • 10: grassland (C3) - GRAS
  • 11: tropical grassland (C4) - TROG
  • 12: peat bogs, parks and gardens (irrigated grass) - PARK
  • 13: tropical broadleaf deciduous - TRBD
  • 14: temperate broadleaf evergreen - TEBE
  • 15: temperate needleleaf evergreen - TENE
  • 16: boreal broadleaf cold-deciduous summergreen - BOBD
  • 17: boreal needleleaf cold-deciduous summergreen - BOND
  • 18: boreal grass - BOGR
  • 19: shrub - SHRB
