Vegetation Imagery from Toolik Lake, Alaska

Toolik plot photo.

A plot photo (#0656) taken at the largest study area "Toolik" at elevation 765.7 m. The small white object was included in many of the photos as a color reference. The photographer's boots are also often visible, in this photo they are to the lower left of the white object.

A new ABoVE dataset offers hundreds of ground-based vegetation photos which may serve as a reference for studies of climate and vegetation change in the area.

Winter Carbon Flux From Arctic & Boreal Soils

Soil CO2 flux estimates.

Mean daily soil CO2 flux in each month of the non-growing season (NGS) during the baseline period (2003-2018). Gridded estimates are provided at 25-km resolution for the pan-Arctic and Boreal permafrost region.

New data from the Arctic-Boreal Vulnerability Experiment (ABoVE) provide winter soil CO2 flux estimates for the pan-Arctic and Boreal regions.

Thirty+ Year Timeseries of Arctic Land Cover

Land Cover Classes.

Land cover (10-class product) for the year 2014 for ABoVE tile BH03V04. The pixel resolution is 30 m and a tile is 180 x 180 km.

Research from NASA's ABoVE project provides annual land cover classifications from 1984 to 2014 for Alaska and the Canadian Arctic.

Two new datasets provide soil active layer thaw depth and end-of-season snow depth at sites near Fairbanks, Alaska.

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.
