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

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.
