- Continuous simulations performed between June 1990
- We used an iterative procedure based on the downhill simplex
method to estimate the values of ?bmax and initial root biomass
that minimizes ? (Observed NDVI - Simulated NDVI)2
- The parameters that have been selected to be re-parameterized
and re-initialized were the Maximum photosynthetic conversion
efficiency ?bmax and the initial root biomass
- the model is highly sensitive to them
- they are spatially variables
- they are difficult to obtain by directs measurements
