Abstract
The Yasso15 model describes cycling of organic carbon in soil (Järvenpää et al. 2015). It is an improved version of an earlier Yasso model (Liski et al. 2005) as well as the Yasso07 model (Tuomi et al. 2009, Tuomi et al. 2011a, Tuomi et al. 2011b). The Yasso07 was based on a substantially larger number of measurements and more advanced mathematical methods than the original Yasso. In addition, uncertainty estimates are a fixed part of Yasso07 results. In the current Yasso15 model, even more diverse data set is used for model calibration as well as some improvements are introduced. Furthermore, in the development of the Yasso15 model more emphasis was put on modelling choices and some mathematical details leading to better understanding of the methods and the underlying environmental processes. Uncertainty estimates are an important part of the Yasso15 model. The Yasso15 calculates the stock of soil organic carbon, changes in the stock of soil organic carbon and heterotrophic soil respiration. Applications the model include, for example, simulations of land use change, ecosystem management, climate change, greenhouse gas inventories and education. The Yasso15 is a relatively simple soil organic carbon model requiring information only on climate and soil carbon input to operate.
