This episode is all about the different "scales" of methane measurements made during MAMM. Whilst the aircraft samples the whole European Arctic region, close-up, small-scale sampling of the wetlands is also done to understand how methane emissions vary within short distances, and how they are linked to vegetation types and the depth of the water table.
Jennifer speaks to Ute Skiba from the Centre for Ecology & Hydrology and finds out about her measurements of methane in the wetlands using chambers, and how these small-scale measurements can be scaled up to the larger, i.e. regional scale, which can then be compared with the regional scale measurements made by the aircraft. Another important greenhouse gas, nitrous oxide - N2O, also gets a mention!
