SP2: Greenhouse gas monitoring and upscaling

Greenhouse gas monitoring and upscaling

Subproject 2 (SP 2) investigates the spatiotemporal variability of land–atmosphere exchange processes of the interconnected greenhouse gas fluxes of CO₂, methane, and nitrous oxide from typical soil–vegetation complexes in heterogeneous permafrost landscapes. The new data will be harmonized with existing datasets, in particular those previously collected in MOMENT, and used for data-driven, machine-learning-based modeling to upscale GHG fluxes. The monitoring program will be conducted from the pedon to the landscape scale in the glacial U-shaped valley Kuup Ilua as well as in higher-elevation proglacial areas. Spatially distributed measurement sites, where high-resolution assessments of soil energy and water budgets and measurements of CO₂, CH₄, and N₂O emission and uptake fluxes are carried out, overlap with the fieldwork and sampling locations of SP 1. The manually collected data will be jointly analyzed together with ongoing long-term landscape-scale measurements from an eddy-covariance flux tower system in Kuup Ilua (operated by the Kutzbach working group within the Cluster of Excellence CLICCS at the University of Hamburg).
