Calibrate GPP & LAI model #1637
Description
Calibrate GPP and Optimal LAI parameters
GPP needs calibration, in particular to address the overestimation of C4 GPP (which may stem from incorrect parameters or a structural issue). Optimal LAI parameters should also be calibrated.
For reference, the current RMSE for monthly Optimal LAI is 1.3, compared to 0.6–1.4 across other LSMs. The target is 0.5.
