Short summary
Short summary
This dataset includes monthly measurements of carbon dioxide and methane exchange between land, water, and the atmosphere from over 1,000 sites in Arctic and boreal regions. It combines measurements from a variety of ecosystems, including wetlands, forests, tundra, lakes, and rivers, gathered by over 260 researchers from 1984–2024. This dataset can be used to improve and reduce uncertainty in carbon budgets in order to strengthen our understanding of climate feedbacks in a warming world.

Short summary
As the soil thaws in summer, the land subsides, owing to the greater volume of ice than of water. This deformation helps monitor water storage because the subsidence magnitude is proportional to water volume. In this study, the interferometric synthetic aperture radar (InSAR) technique was used to map subsidence around Toolik Lake, Arctic Alaska. Both InSAR and field observations suggest that soil water storage ranges from 0 to 75 cm, with small errors, and that the spatial distribution of soil water correlates strongly with topography and vegetation.
