Manual chamber Ch4, CO2, N2O fluxes + auxiliary data from Stordalen Mire, N Sweden, 2023

This dataset contains greenhouse gas fluxes (N2O, CO2, and CH4) and auxiliary data, including PAR (Photosynthetically Active Radiation), soil moisture, and soil temperature from manual chamber campaigns at the Stordalen Mire (68.20°N, 19.03°E, 351m above sea level) in sub-Arctic Sweden in May, July, and September 2023.

The Stordalen Mire is located within the sporadic permafrost zone, adjacent to lake Torneträsk. A large portion of the mire consists of a slightly elevated drained area, altered by wetter depressions, which are not underplayed by permafrost. It is located on the 0°C isotherm which causes the permafrost in the mire to be of sporadic and of very dynamic nature. As a result of recent years warming in the area permafrost has been observed to degrade in many parts of the mires.

Our dataset is grouped in four different micro habitats along a thawing (moisture) gradient from dry to wet: palsa lichen (dry), palsa moss (dry), bog (wet), and fen (wet). Please refer to our publications.
