Radar profiling data collected on Breidamerkurjokull in 2009
Listed in NASA Earthdata CMR
5-MHz ground-based radar data were collected along three transects roughly follow the ice-flow direction.
Description
These three profiles are located each in slow (150-200 m/a, transect a), intermediate (150-250 m/a, transect b), and fast (300-400 m/a, transect c) -flowing regimes of the glacier. Two profiles (a1 and a2) were made for the slow-flow transect for the redundancy purpose.
The data are provided in Matlab format. Each profile (a1, a2, b1, c1) has structure including: horizontal positions x and y in the UTM coordinate (meters), vertical position z above the WGS84 ellipsoid (meters), radar waveform (1024 samples per trace), corresponding two-way travel time (seconds), sampling rate of the radar waveform in nanosecond (10 nsec for this dataset), and days of the year of 2007 and seconds of the day when each radar trace is recorded.

No processing is applied to the radar waveforms. However, the echo from the basal interface of the glacier and echoes from within the glacier are clearly recorded.
