ABoVE

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.

Monitoring Permafrost with P-Band SAR

Active layer thickness and uncertainty.

Active layer thickness with uncertainty for a flight swath over the northern section of Alaska's Dalton Highway in summer 2015.

NASA's ABoVE airborne campaign provides estimates of active layer thickness and soil properties derived from the AirMOSS instrument.

Uncertainty in Arctic Carbon Stocks and Fluxes

Uncertainty of carbon stock across the ABoVE domain.

Uncertainty in soil carbon stocks and gross primary productivity across the ABoVE domain.

Work from NASA's ABoVE compared model outputs to estimate the uncertainty in six components of the carbon cycle across Alaska and Canada.
