N2 - The Greenland ice sheet has experienced an average mass loss of 142 ± 49 Gt/yr from 1992 to 2011 (Shepherd et al.
2012), making it a significant contributor to sea-level rise. Part of
the ice- sheet mass loss is the result of increased dynamic response of
outlet glaciers (Rignot et al. 2011). The ice discharge from
outlet glaciers can be quantified by coincident measurements of ice
velocity and ice thickness (Thomas et al. 2000; van den Broeke et al. 2016). As part of the Programme for monitoring of the Greenland Ice Sheet (PROMICE; Ahlstrøm et al.
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 et al.
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.
