We present here the simulation tests at two tropical broadleaf evergreen tree sites (PFT = 2):

  • BR-Sa3 in Brazil
  • ID-Pag in Indonesia.

Simulation are done with ORCHIDEE_CN r3714 (CN3714OLDRES, CN3714RESTIME, CN3714KLAT and CN3714NEWCN) and r3823 (CN3823RESTIME, CN3823SLA and CN3823SLA02).

Setting

The parameter setting of the different simulations is shown in the table below. The parameters are set only for PFT=2, as we consider the whole cell covered by this PFT. All the other parameters, forcing files, configuration run are the same for all simulations.

Results

  1. Using the same RESIDENCE_TIME as in the ORCHIDEE trunk configuration (30.0 yr) the total biomass is significantly decreased, giving more reasonable results (all simulation except CN3714OLDRES).
  1. Decreasing RESIDENCE_TIME is not enough to correct the GPP and the different biomass stocks (CN3823RESTIME, pink line).
  1. Using the same RESIDENCE_TIME and TAU_SAP of the ORCHIDEE trunk configuration (30.0 yr and 730 days, respectively), brings to significant decrease of GPP, NPP, LAI and leaf mass. This decrease anyway is too high (CN3714RESTIME, green line in the figures).
  1. Decrease of TAU_SAP means having less sapwood area and consequently less leaf area. To partly offset the strong LAI decrease we can increase the K_LATOSA parameters (K_LATOSA_MIN and K_LATOSA_MAX), that drive, in the allocation scheme, the proportion between sapwood and LAI (the higher K_LATOSA, the higher the fraction of LAI with respect to sapwood). In CN3714KLAT (red line) we doubled the K_LATOSA_MIN and K_LATOSA_MAX, obtaining higher and more reasonable values of LAI.
  1. Increasing the CN ratio CN3714NEWCN, we impose less nitrogen in the leaf that induces less GPP and lower VCMAX, but has a low impact on the LAI (look CN3714NEWCN vs CN3714KLAT, light blue and red line, respectively).
  1. The impact of dynamic SLA depends on the SLA_INIT. Low SLA_INIT (CN3823SLA, light green line) leads to lower LAI and slightly lower GPP in comparison to CN3714KLAT (red line) simulation, while higher SLA_INIT (CN3823SLA02, black line) leads to higher LAI, GPP and NPP.
