Time series of autonomous phase-sensitive radar (ApRES) measurements for basal melt rate estimations at location ApRES1 on 79°N Glacier from August 2016 to June 2022
The dataset consists of raw data from autonomous phase-sensitive radar (ApRES) measurements. The ApRES was operated with two bow-tie antennas on the surface in the ablation zone of the 79°N Glacier in Northeast Grenland since 2016. These Lagrangian measurements allow the estimation of basal melt rat...

description |
The dataset consists of raw data from autonomous phase-sensitive radar (ApRES) measurements. The ApRES was operated with two bow-tie antennas on the surface in the ablation zone of the 79°N Glacier in Northeast Grenland since 2016. 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, 20 to 100 chirps were transmitted within a single measurement. These measurements were repeated at time intervals between 15 minutes and 6 hours. A raw data file contains up to 4 measurements. Background of the pRES-system is published by Nicholls et al. (2015). The processing of the data is described in Zeising et al. (2024). |
