Sub-Meter Scale Vegetation Maps for Toolik Lake, Alaska

Vegetation communities.

Vegetation communities for the Toolik footprint shown at 1:25,000 scale.

Plant communities near Toolik Lake research station in Alaska were classified at 20 cm resolution based on airborne imagery and lidar surveys.

Spectral Reflectance of Tundra Plants

Common Garden Ecotype site.

A plot at a common garden ecotype site near Eagle Creek, Alaska. Common garden sites were established with different populations of the tussock-forming sedge taken from different latitudes in Alaska.

Researchers with the Arctic-Boreal Vulnerability Experiment (ABoVE) measured plot-level and species-specific full-spectrum reflectance data for tundra plants.

MODIS MAIAC at ABoVE Flux Towers

ABoVE domain.

New MAIAC data were calculated at 62 flux tower sites within the ABoVE domain in Alaska and Canada.

MODIS Multi-Angle Implementation of Atmospheric Correction algorithm (MAIAC) surface reflectances are available for 62 flux tower sites in the ABoVE domain.

River Ice Breakup and Freeze-up Stages from ABoVE

Freeze-up stages.

Examples of freeze-up stages in the Grayling study area. Landsat images are displayed as color composites (R: SWIR, G: NIR, B: green), where water appears dark blue and snow/ice appears light blue.

Estimates of river ice breakup and freeze-up stages along selected reaches of the Yukon and Tanana Rivers in the Yukon River Basin in interior Alaska from 1972-2016 are now available from ABoVE.

Soil Temperature Profiles for Interior Alaska

USArray measurement sites

USArray measurement sites in Alaska. Sites are labeled with site ID and maximum measurement depth and color-coded by mean annual ground temperature (MAGT in degrees C) of the deepest sensor measurements. Data are omitted for sites disrupted by bears.

Soil temperature data were collected at Alaskan USArray seismic monitoring sites from 2016-2018.
