Compendium on methods and tools to evaluate impacts of, and vulnerability and adaptation to, climate change


MC1
Description

MC1 consists of three linked modules simulating biogeography, biogeochemistry, and fire disturbance. The main functions of the biogeography module are to:

  1. Predict the composition of deciduous/evergreen tree and C3/C4 grass lifeform mixtures,
  2. Classify the predicted biomass from the biogeochemistry module into different vegetation classes.

The biogeochemistry module simulates monthly carbon and nutrient dynamics for a given ecosystem. Above- and below-ground processes are modeled in detail, and include plant production, soil organic matter decomposition, and water and nutrient cycling. Parameterization of this module is based on the lifeform composition of the ecosystems, which is updated annually by the biogeography module.
