Radar monitoring data collected at two locations in June, 2009, Breidamerkurjokull
Listed in NASA Earthdata CMR
5-MHz ground-based radar system was located on two places on Breidamerkurjokull for several days to measure temporal changes of englacial and subglacial properties.
Description
The data file includes two structures: Site A and Site B. Each structure includes two radar waveforms (ch0 for a wider amplitude range and ch1 for a narrower amplitude range), corresponding two-way travel time, and time when each radar data was collected (julian day, hour, minute, second, and timestamp = jday + (hour + minute./60 + second./3600)./24).
We replaced the batteries of the radar system every day, which is not frequent enough to collect the data continuously. The users of this dataset should pay attention to temporal changes of the radar-transmitting power. Amplitudes of the direct wave can be used to measure this feature caused by decreased voltage of the power supply.
