Fa Li works on the data visualizations that accompany the research.
The figure from the recently published paper shows the distribution of methane emissions in the Boreal-Arctic thanks to the upscaled data set of tower and chamber data combined by the researchers. Soil chamber sites are denoted as yellow dots while the towers are red. Emissions hotspots are outlined in dotted red lines. The accompanying graph shows methane emissions, which are increasing over time while the area of land covered by wetlands slightly decreases.
Scientists have been measuring global methane emissions for decades, but the boreal arctic —with a wide range of biomes including wetlands that extend across the northern parts of North America, Europe and Asia — is a key region where accurately estimating highly potent greenhouse gas emissions has been challenging.
