Polarimetric ApRES data on a profile across Dome C, East Antarctica, 2013-2014
The radar data collected in 2013-2014 at Dome C, East Antarctica, aims to understand bulk preferred crystal orientation fabric near a dome. We measure changes in englacial birefringence and anisotropic scattering in 21 sites along a 36 km long profile across Dome C. These optical properties are obtained by analysing radar returns for different antenna orientations. More details can be found in Ershadi et al, 2021.

- Statement
-
The quality of the data is similar in all the sites. It varies mainly with depth: In the top 2000 m the return is consistently above the noise level. Below 2000 m, the return signal is weak, apart from some isolated reflectors, up to the bedrock that is clear in all the records.
The parallel antenna configuration measurements, HH and VV, have larger signal-to-noise ratio, than the perpendicular ones, HV and VH. This is because of experimental design as system configuration is identical in all the antenna orientations.
