Release of greenhouse gases from northern soils contribute significantly to the global atmosphere and play an important role in regulating climate. This study, based in N. Finland, aimed to measure and understand the release of CH4
O, and using satellite imagery, upscale our results to a 2 × 2 km area. Wetlands released large amounts of CH4
, with emissions linked to temperature and the presence of Sphagnum; landscape emissions were 2.05 mg C m−2
O fluxes were consistently near-zero.
