Greenhouse Gases research group
The Greenhouse Gases research group studies greenhouse gas concentrations and their exchange between the atmosphere and different ecosystems experimentally and theoretically.

The research is based on internationally well-calibrated atmospheric concentration and ecosystem net gas flux measurements carried out in multiple locations both in Finland and abroad. The main research station is Pallas-Sodankylä observatory which is one of the main WMO Global Atmosphere Watch sites on high latitudes.
The research group runs most of the ICOS-Finland sites providing greenhouse gas data to the European Integrated Carbon Observation System (ICOS) network. As part of the ICOS activities, the new well-calibrated atmospheric concentration sites cover all parts of Finland. Instrumentations in the ecosystem flux sites are extended to support various ecological research.
The research group is part of Nordic Centre of Excellence DEFROST (Impacts of a changing cryosphere - depiciting ecosystem-climate feedbacks from permafrost, snow and ice) and Finnish Centre of Excellence in Physics, Chemistry, Biology and Meteorology of Atmospheric Composition and Climate Change.
