Impacts of microtopography on hydrologic and thermal states in an Arctic ecosystem: A case study using ELM-3D v1.0
Using a new three-dimensional hydrological and thermal capability in ELM (ELM-3D), scientists at LBNL analyzed the role of snow redistribution and lateral interconnectivity on soil temperatures and active layer.
Modeling the role of vegetation-induced preferential snow accumulation in open talik development and hillslope groundwater flow in a transitional permafrost landscape
The role of distributed snow on permafrost distribution along the hillslope at Teller field site
Symbiotic N-fixation by alder impacts nitrogen availability on a landscape scale
Nitrogen fixed within root nodules of alder growing in dense shrublands is associated with higher levels of local N availability. The inclusion of a plant functional type based on this N-fixing shrub may improve earth system models’ ability to capture nit
Coupling PFLOTRAN into E3SM through collaboration between the CMDV and NGEE Arctic projects
The NGEE Arctic PFLOTRAN biogeochemistry (BGC) is coupled to the E3SM Land Model (ELM) through a generic interface and the ELM-PFLOTRAN is being evaluated at both point and global scales.
Modeling anaerobic soil organic carbon decomposition in Arctic polygon tundra: Insights into soil geochemical influences on carbon mineralization
Linking soil geochemistry with carbon decomposition improves predictions of CO2 and CH4 production along fine-scale hydrological variabilities in Arctic soil and permafrost.
Factors affecting the spatial pattern of snow distribution at the NGEE Arctic Teller and Kougarok watersheds
High resolution snow data collected from two small catchments in the southern Seward Peninsula was used to identify key factors that control snow distribution, quantify the relative impacts of those factors and improve the snow representation for the arct
