ICOS Talks is a series of online presentations and discussions by scientists, for scientists. These talks showcase groundbreaking greenhouse gas science topics facilitated by ICOS data.

He is the principal investigator of the ICOS Ecosystem stations at Svartberget and Degerö in northern Sweden. His research focuses on biosphere–atmosphere exchanges across boreal forest landscapes. Abstract Boreal forests represent an important global carbon sink. However, their sink strength remains poorly constrained due to inherent limitations of standard measurement approaches in capturing processes across spatial and temporal scales. Here, Matthias presents a spatially-nested measurement framework based on ICOS infrastructure that integrates bottom-up (forest plot inventories and chamber-based flux measurements) and top-down (eddy-covariance and atmospheric observations) approaches to reconcile the carbon balance of managed boreal forests in northern Sweden across plot, ecosystem, landscape, and regional scales. The talk highlights the value of integrated multi-scale monitoring platforms that co-locate bottom-up and top-down approaches to advance our understanding of terrestrial carbon-cycle–climate feedbacks.
