Representing Complex Consumer-Substrate Networks: Development for ESM Land Models with an Application to Litter Decomposition
Current ESM land models lack mechanistic representation of substrate (e.g., C and N) competition and the resulting decomposition kinetics. Our goals were to develop a new concept for representing these dynamics (using the total quasi-steady state assumption and perturbation theory) in a manner applicable to CLM4.5.
