Video: The increase in carbon dioxide and methane concentrations shows in measurements made at Pallas, Finland


The measurements made in the Pallas-Yllästunturi National Park reveal the increase of carbon dioxide and methane concentrations and their seasonal variation. The carbon dioxide concentration has been increasing since the monitoring at Pallas began. It reaches the highest level in winter and decreases during the growing season. At Pallas the seasonal cycle of methane is not as regular as the cycle of carbon dioxide, and it also shows the local methane emissions from wetlands.
