    • Timeseries of Arctic-Boreal Lake Area Derived from CubeSat Imagery, 2017

    Metadata Updated: December 7, 2023

    This dataset provides near-daily lake area timeseries for 85,358 lakes across four study areas in Northern Canada and Alaska, USA, between May 1 and October 1, 2017. These lake area estimates were produced using digital images from newly developed Planet Labs CubeSats, small satellites with a 4-band (blue, green, red, near-infrared) camera payload. In constellation, CubeSats collected imagery at very high spatial (3-5m) and temporal (near-daily) resolution. From the imagery, each lake's mean, minimum, and maximum areas and seasonal dynamism were derived. The dataset covers four Arctic-Boreal regions: the Yukon Flats Basin (YFB) in eastern interior Alaska, and the Mackenzie River Valley (MRV), Canadian Shield Transect (CST), and Hudson Bay Lowland (HBL) in Canada.

    Gridded maps of lake dynamism (seasonal maximum minus seasonal minimum lake area, km2) for the study areas derived from CubeSat imagery. White dashed lines show major river systems. Stars indicate locations of in-situ lake level measurements used for validation. From Cooley et al. (2019).
