Soil carbon model Yasso07
With respect to variables in natural ecosystems, this Climate guide only includes scenarios related to leaf litter decomposition. Future estimates of leaf litter decomposition are based on results from the soil carbon model Yasso07.
Soil carbon model Yasso07
The soil carbon model Yasso07 describes the release of carbon dioxide as a consequence of leaf litter decomposition [1]. The model assumes that different types of carbon compounds in the soil decompose at different speeds. In addition to the air temperature, the decomposition speed is affected by moisture in the soil, for example. The model calculates the changes in the stock of soil organic carbon and the amount of carbon dioxide released from the soil over a specific period of time. The Yasso model is used for the greenhouse gas calculations in Finland and some other countries. In addition, the model is widely used in research.[2]
