Permafrost thaw and resulting soil moisture changes regulate projected high-latitude CO2 and CH4 emissions (2015, background): “…simulation and projection of key thermal, hydrologic, and biogeochemical processes that are thought to be relevant for permafrost and its response to climate change (Lawrence and Slater 2007, Lawrence et al 2008, Riley et al 2011, Swenson and Lawrence 2012, Swenson et al 2012, Koven et al 2013b).”
The Community Land Model Version 5: Description of New Features, Benchmarking, and Impact of Forcing Uncertainty (2019, methodology): “The snow cover fraction parameterization was revised to reflect hysteresis in fractional snow cover, for a given snow depth, between accumulation and melt phases (Swenson & Lawrence, 2012).”
Global Mean Climate and Main Patterns of Variability in the CMCC‐CM2 Coupled Model (2018, background): “The hydrology processes list modifications related with treatment of icy permafrost ground (Swenson et al., 2012) and improve the simulation of snow cover fraction (Swenson & Lawrence, 2012), by separating the processes governing snowmelt (i.e., depletion) and snowfall (i.e., accumulation).”
