Data from: Low-frequency radar sounding of ice in East Antarctica and southern Greenland

We share data from a decameter-wavelength airborne radar sounder, the Warm
Ice Sounding Explorer (WISE), that provides ice thickness in areas where
radar signal penetration at higher frequencies is expected to be limited.
We share results for three campaigns conducted in Greenland (2008, 2009,
2010) and two in Antarctica (2009, 2010). Comparisons with
higher-frequency radar data indicate an accuracy of 55 m for ice-thickness
measurements in Greenland and 25 m in Antarctica. We also estimate ice
thickness of the Qassimiut lobe in southwest Greenland, where few
ice-thickness measurements have been made, demonstrating that WISE
penetrates in strongly scattering environments.
