Coping with scale issues in modelling nitrous oxide and methane emissions from soils

摘要

Soils are important sources of atmospheric nitrous oxide (N_2O) and methane (CH_4). Process-based models are useful tools in exploring management measures to reduce these emissions. In order to scale up the basic production, consumption and transport processes to the field scale, simplifying assumptions have to be made. The validation of these simplifications is a major challenge for future modelling work.
