The dataset refere to the data collected on Mount Etna on two sites (Site1 and Site2) and published on Journal of Geophysical Research: Planets.
 
Two types of data are present: TDR data and GPR data.

1) GPR data have been collected using different antenna systems (500 MHz and 1MHz) and polarization (TE and TM)

Data description:
  
the first row represents the postion of the GPR along track
the first column represents the time in ns
the echo amplitudes (in arbitary units) acquired by the radar are the remanaing data 
  
  
2) TDR data have been collected using three different probes (s1,s2,s3) in different locations (p1, p2,...)

the probe s1 is characterized by a length of 0.1 m and a characteristic impedance of 221 Ohm 
the probe s2 is characterized by a length of 0.21 m and a characteristic impedance of 113 Ohm 
the probe s3 is characterized by a length of 0.08 m and a characteristic impedance of 233 Ohm 

Data description:
	
the first column represents the time in ns
the second column represents the amplitude of TDR trace in arbitary units
