  • LSPINUPCARBS : if T, to do the soil carbon spinup

  • XSPINMAXS : This key defines the spinup time step as the increase of the physical time step by a factor equal to XSPINMAXS. So, if the physical (isba time step) = 300s and XSPINMAXS = 50, then the carbon spinup time step = 15000s.

  • NNBYEARSPINS : number of years needed to reach soil equilibrium (spinup time step is at its maximum during 80% of the defined NNBYEARSPINS, then decrease linearly to reach the physical time step). So, if XSPINMAXS = 50 and NNBYEARSPINS =250, the spinup procedure is at maximum during 200 physical years representing 200x50 = 10 000 carbon years.

  • XMISSFCO2 : Missing carbon flux (cf. anthropic) required for ESM coupling in emission mode (default = 0.)

  • LFIRE : flag to activate simple biomass fire module

  • LCLEACH : flag to activate soil carbon leaching that produce dissolved organic carbon that can be routed by CTRIP

  • LADVECT_SOC : flag to activate vertical advection scheme for soil dynamics carbon module, only if CRESPSL = DIF (in NAM_PREP_ISBA_CARBON)

  • LCRYOTURB : flag to activate vertical cryoturbation scheme if CRESPSL = DIF (in \

  • LBIOTURB : flag to activate vertical bioturbation scheme if CRESPSL = DIF (in \
