Autonomous phase-sensitive radar (ApRES) measurements at EastGRIP drill site, Greenland

The dataset consists of raw data from autonomous phase-sensitive radar (ApRES) measurements. The ApRES with two broadband frame antennas was operated within a trench (~10 m below the surface) at the EastGRIP drill site on the Greenland Ice Sheet (-35.997°W, 75.630°N) between 08/2017 - 04/2018 and 08/2018 - 05/2019 with a one day interval. These Lagrangian measurements allow the estimation of basal melt rates based on estimated vertical displacements of englacial and basal reflections. The ApRES is an autonomous operating frequency-modulated continuous wave (FMCW) radar that transmits a tone sweep – called chirp – ranging from 200 to 400 MHz over a period of one second. In order to improve the signal-to-noise ratio, 100 chirps were transmitted within a single measurement. These measurements were repeated every 24 hours. Background of the pRES-system is published by Brennan et al. (2014) and Nicholls et al. (2015). The processing of the data is described in Stewart (2018), Stewart et al. (2019) and Vankova et al. (2020).
