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
A Subgrid Approach for Modeling Microtopographic Effects on Overland Flow: Application to Polygonal Tundra
The effects of fine-scale topography can be represented in models with coarser spatial resolution through the use of a new subgrid model, thus enabling computationally demanding integrated surface/subsurface hydrology models to be used at field scales
Plant Traits Across an Arctic Landscape: Above versus Belowground
NGEE Arctic researchers are quantifying above and belowground variation in plant functional traits across environmental gradients to inform the representation of plant traits in terrestrial biosphere models.
Evapotranspiration across Plant Types and Geomorphological Units in Polygonal Arctic Tundra
A field research showed that evapotranspiration from mosses and open water was twice as high as that from lichens and bare ground, and that microtopographic variations in polygonal tundra explained most of this and other spatial variation
