Water limitation in diffuco_trans_co2

Reported by: dsolyga Owned by: nicolasviovy
Priority: minor Milestone:
Component: Biogeochemical processes Version: orchidee_1_9_6
Keywords: water stress, diffuco Cc: nviovy


The following formulation used to calculate water limitation in diffuco :

      WHERE ( assimilate(:) )
        water_lim(:) = MIN( 2.*humrel(:,jv), un )

could be replaced by the formulation used in the Assimilation branch :

WHERE ( assimilate(:) )
      water_lim(:) = 2./(1+EXP(-opti_fstressh(jv)*humrel(:,jv)))-1.


Need to add a new pft parameter called opti_fstressh and maybe the externalization of the scalar parameters equations in the new formulation.


Study the differences between the 2 formulations.
