Outline of Final Research Achievements

Ecosystem-scale CH4 exchange between forest and the atmosphere was measured using the hyperbolic relaxed eddy accumulation method with the automated closed chamber measurement. The measurements were conducted at three temperate forests and one sub-arctic forest. We found that three of the four forests acted as net CH4 source at the annual timescale. The sources could be contributed by sporadically located hotspot emissions within the flux footprint. Our findings suggest that previous CH4 sink at global upland forests are overestimated; thus, revisiting CH4 budget at forest ecosystems are required. Our system combining the micrometeorological and chamber methods are useful for understanding CH4 budget at the point to ecosystem scales.
