Part of the ice- sheet mass loss is the result of increased dynamic response of outlet glaciers (Rignot <em>et al.</em> 2011). The ice discharge from outlet glaciers can be quantified by coincident measurements of ice velocity and ice thickness (Thomas <em>et al.</em> 2000; van den Broeke <em>et al.</em> 2016). As part of the Programme for monitoring of the Greenland Ice Sheet (PROMICE; Ahlstrøm <em>et al.</em> 2008), three airborne surveys were carried out in 2007, 2011 and 2015, with the aim of measuring the changes in Greenland ice-sheet thicknesses. The purpose of the airborne surveys was to collect data to assess the dynamic mass loss of the Greenland ice sheet (Andersen <em>et al.</em> 2015). Here, we present these datasets of observations from ice-penetrating radar and airborne laser scanning, which, in combination, make us able to determine the ice thickness precisely. Surface-elevation changes between surveys are also presented, although we do not provide an in-depth scientific interpretation of these.</p> ER -
