NGEE Arctic Returns to San Francisco for its Ninth All-Hands Meeting

Scientists from across the country gather for their ninth annual NGEE Arctic All-Hands meeting to celebrate success and discuss progress and plans for the project.

Investigations of topographic control on thermokarst development and the ground thermal regime in ice wedge polygons using the Advanced Terrestrial Simulator

NGEE Arctic researchers found that rim height and trough depth in ice wedge polygons considerably influence the vulnerability of the underlying permafrost, shaping feedbacks which ultimately control topographic deformation and increased soil aeration in t

NGEE Arctic scientists attend NASA ABoVE annual meeting

Shawn Serbin represented NGEE Arctic at the NASA ABoVE meeting, showcasing our science and identifying opportunities for synergy with NASA ABoVE.

Characterization of permafrost landscapes using an unmanned aerial system: LiDAR mapping the NGEE Arctic Teller field site

A state-of-the-art unmanned aerial system was deployed to collect centimeter-resolution imagery and topographic data of the NGEE Teller research site.

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

Convolutional neural network approach for mapping Arctic vegetation using multi-sensor remote Sensing fusion

Deep learning models achieve multi-sensor remote sensing fusion for mapping of Arctic vegetation

Modeling the impacts of fire on surface energy and land-atmosphere carbon exchange across Alaska

Impacts of fire on the long-term net ecosystem productivity were modeled across selected sites in Alaska.

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.
