ORCHIDEE-TRUNK OPTIMIZATION
ROUND8 (11/03/2024)
Select: |
Update (06/10/2024)
A bug has been found in the calculation of error associated to each simulated variable that is further used in the cost-function calculation. As an effect the control variables were badly weighted and some variables were given much more priority during the sim-obs tuning.
Optimization is redone for crops with corrected error calculation (PFT12c, PFT13c)
