Greenhouse Gas Modelling
The Greenhouse Gas Modelling Group studies the circulation of carbon dioxide and methane between vegetation, soil, and the atmosphere. We combine observations and modelling to assess how natural processes and human activities influence greenhouse gas emissions and sinks, particularly in northern ecosystems.
Our research group studies how greenhouse gases are transported in the atmosphere and which factors influence their concentrations and variability. We focus particularly on northern ecosystems, such as peatlands, wetlands, and forests, and investigate how the underlying processes in these environments release and absorb greenhouse gases as part of their natural cycles. In addition, we examine the impacts of human activities—such as peatland restoration, forest management, and climate change—and assess how these changes are reflected in greenhouse gas emissions and sinks. We also consider direct emissions caused by human activities, for example from traffic and industry.
Our methods are based on combining observations and modelling. We use measurements from ecosystem stations as well as observations made in the atmosphere, complemented by various computational models. With these tools, we can estimate the sources and sinks of greenhouse gases both locally and across broader regions in Finland and globally.
We participate in the international ICOS and WMO-G3W collaborations. In Finland, we support greenhouse gas inventories by providing observation-based estimates of emissions and sinks.
