Integrating bottom-up and top-down methods to estimate the variability of the Siberian carbon balance

Siberia plays a critical role in the global carbon cycle due to its vast boreal forests, permafrost soils, and wetlands, which together act as both major carbon reservoirs and potential sources of greenhouse gas emissions under a warming climate. However, large uncertainties remain in quantifying the magnitude and variability of Siberia’s carbon balance, particularly given strong seasonal dynamics, interannual variability, and the sensitivity of permafrost carbon to climate change. This project aims to integrate bottom-up and top-down approaches utilising the ZOtino Tall Tower Observatory long-term dataset to better constrain the spatial and temporal variability of the Siberian carbon balance.
