  • A new approach to simulate peat accumulation, degradation and stability in a global land surface scheme (JULES vn5.8 accumulate soil) for northern and temperate peatlands 
    Chadburn, Sarah E.; Burke, Eleanor J.; Gallego-Sala, Angela V.; Smith, Noah D.; Bret-Harte, M. Syndonia; Charman, Dan J.; Drewer, Julia; Edgar, Colin W.; Euskirchen, Eugenie S.; Fortuniak, Krzysztof; Gao, Yao; Nakhavali, Mahdi; Pawlak, Wlodzimierz; Schuur, Edward A. G.; Westermann, Sebastian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract. Peatlands have often been neglected in Earth system models (ESMs). Where they are included, they are usually represented via a separate, prescribed grid cell fraction that is given the physical characteristics ...
  • Carbon stocks and fluxes in the high latitudes: Using site-level data to evaluate Earth system models 
    Chadburn, Sarah E.; Krinner, Gerhard; Porada, Philipp; Bartsch, Annett; Beer, Christian; Belelli Marchesini, Luca; Boike, Julia; Ekici, Altug; Elberling, Bo; Friborg, Thomas; Hugelius, Gustaf; Johansson, Margareta; Kuhry, Peter; Kutzbach, Lars; Langer, Moritz; Lund, Magnus; Parmentier, Frans-Jan Willem; Peng, Shushi; van Huissteden, Ko; Wang, Tao; Westermann, Sebastian; Zhu, Dan; Burke, Eleanor J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    It is important that climate models can accurately simulate the terrestrial carbon cycle in the Arctic due to the large and potentially labile carbon stocks found in permafrost-affected environments, which can lead to a ...
  • Consequences of permafrost degradation for Arctic infrastructure - Bridging the model gap between regional and engineering scales 
    Schneider Von Deimling, Thomas; Lee, Hanna; Ingeman-Nielsen, Thomas; Westermann, Sebastian; Romanovsky, Vladimir; Lamoureux, Scott; Walker, Donald A.; Chadburn, Sarah E.; Trochim, Erin; Cai, Lei; Nitzbon, Jan; Jacobi, Stephan; Langer, Moritz (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Infrastructure built on perennially frozen ice-rich ground relies heavily on thermally stable subsurface conditions. Climate-warming-induced deepening of ground thaw puts such infrastructure at risk of failure. For better ...
  • Explicitly modelling microtopography in permafrost landscapes in a land surface model (JULES vn5.4_microtopography) 
    Smith, Noah D.; Burke, Eleanor J.; Aas, Kjetil Schanke; Althuizen, Inge; Boike, Julia; Christiansen, Casper Tai; Etzelmüller, Bernd; Friborg, Thomas; Lee, Hanna; Rumbold, Heather; Turton, Rachael H.; Westermann, Sebastian; Chadburn, Sarah E. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Microtopography can be a key driver of heterogeneity in the ground thermal and hydrological regime of permafrost landscapes. In turn, this heterogeneity can influence plant communities, methane fluxes, and the initiation ...
  • Modeled Microbial Dynamics Explain the Apparent Temperature Sensitivity of Wetland Methane Emissions 
    Chadburn, Sarah E.; Aalto, Tuula; Aurela, Mika; Baldocchi, Dennis; Biasi, Christina; Boike, Julia; Burke, Eleanor J.; Comyn-platt, Edward; Dolman, A Johannes; Duran-Rojas, Carolina; Fan, Yuanchao; Friborg, Thomas; Gao, Yao; Gedney, Nicola; Göckede, Mathias; Hayman, Garry D.; Holl, David; Hugelius, Gustaf; Kutzbach, Lars; Lee, Hanna; Lohila, Annalea; Parmentier, Frans-Jan W.; Sachs, Torsten; Shurpali, Narasinha J.; Westermann, Sebastian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Methane emissions from natural wetlands tend to increase with temperature and therefore may lead to a positive feedback under future climate change. However, their temperature response includes confounding factors and ...
