Description

I plotted the changes in LAI and TWLV (outputs of the leafdynamics model) with respect to variations in the parameters SPAN and TDWI for every test file in the PCSE test folder. The notebook is available here.

From the plots, it seems that the parameter SPAN does not affect TWLV , see plot 2.2. For LAI, after SPAN reaches a certain threshold, further changes do not appear to affect the output either, see plot 2.1. Is this expected behavior of the leaf_dynamics module?

Additionally, how do other parameters in this model (and in other modules) influence the outputs? It would be good to know this in advance when calculating gradients of an output w.r.t. a parameter.

Research direction

Start with pcs_playground.ipynb and the PCSE tests referenced in the issue, focusing on the leafdynamics model and the LAI, TWLV, SPAN, and TDWI relationships. Compare the plotted behavior with the model's documented or implemented parameter effects. Done means explaining whether the observations are expected and documenting how parameters influence outputs and gradients across the relevant modules.
