“…The data are used to evaluate the horizontal extent of firn aquifers and ice layers simulated by the two numerical models. The Accumulation Radar was built and is operated by the Center for Remote Sensing of Ice Sheets (CReSIS) at the University of Kansas to image near-surface (up to approximately 400 m depth) internal structure of the ice sheet with a 65 cm vertical resolution (Rodriguez-Morales et al, 2014). The Accumulation Radar is well suited to image the presence of a water table in the firn characterized by a bright reflector in the radar images Miège et al, 2016).…”

“…The sounder has a frequency range from 180 to 210 MHz, corresponding to a centre wavelength ∼ 0.87 m in ice. After accounting for pulse shaping and windowing, this results in a depth-range resolution in ice of ∼ 4.3 m (Rodriguez- Morales et al, 2014;Paden, 2015). For the flight lines considered, the alongtrack resolution after synthetic aperture radar (SAR) processing and multi-looking is ∼ 30 m with an along-track-sample spacing of ∼ 15 m .…”

“…The snow radar operates over the frequency range from ∼ 2 to 6.5 GHz (Panzer et al, 2013;Rodriguez-Morales et al, 2014). The snow radar uses an FMCW design to provide a vertical-range resolution of ∼ 4 cm in snow/firn, capable of resolving annual layering, where preserved, to tens of meters in depth (Medley et al, 2013).…”

“…In the past 2 decades, climate warming over the Greenland Ice Sheet (GrIS) has accelerated its mass loss, nearly quadrupling from ∼ 55 Gt a −1 between 1993 and 1999 (Krabill et al, 2004) to ∼ 210 Gt a −1 , equivalent to ∼ 0.6 mm a −1 of sea-level rise, between 2003(Shepherd et al 2012. As GrIS mass loss has accelerated, a fundamental change in the dominant mass loss process has occurred (e.g.…”
