Model of Acidity Dynamics and Organic Carbon (MADOC)

MADOC predicts the effects of nitrogen and sulphur deposition (from air pollution) on soil acidity and carbon uptake and/or emissions. It is used by researchers to project future impacts of, and recovery from, air pollution on ecosystems and ecosystem services, such as: (1) acidification and eutrophication (for Defra); (2) biodiversity (here MADOC is coupled to MultiMOVE: see separate entry); (3) heavy metal solubility and soil concentrations (here MADOC is coupled to IDMM: see separate entry).
