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.

Active Layer Thickness Across Northern Alaska

Active layer thickness.

Active layer thickness product (ALT) at 30 m resolution near Barrow (Utqiagvik), Alaska.

New data from NASA's Arctic-Boreal Vulnerability Experiment (ABoVE) provide estimates of active layer thickness from airborne radar.

Monthly Hydrological Fluxes for ABoVE Domain

Average annual precipitation.

Average annual precipitation for 1979-2010 at 0.25 degree resolution across the Arctic Boreal Vulnerability Experiment study domain.

Estimated historical water balance climatologies are available for the Arctic-Boreal Vulnerability Experiment (ABoVE) study domain.

Temporal Dynamics of Lake Area in the Arctic

Four ABoVE study sites.

Near-daily CubeSat imagery was collected within four large regions across the ABoVE study area. Timeseries of lake area were derived from the CubeSat imagery for more than 80,000 lakes in these regions.

Near-daily CubeSat imagery provides information on the seasonal dynamics of more than 80,000 lakes.

Greenhouse Gases from Arctic-CAP

Monitoring carbon dynamics during the 2017 growing season.

Arctic-CAP flight lines (orange) sampled Arctic and boreal regions of Alaska and Canada. Pins mark the locations of vertical profiles that were repeatedly acquired during the 2017 growing season.

Atmospheric carbon and methane concentrations were measured during the 2017 Arctic Carbon Aircraft Profile (Arctic-CAP) flights throughout Alaska and western Canada.
