Abstract
The dataset contains radargrams from the 2004-2005 airborne radar sounding surveys on Pine Island Glacier and Thwaites Glacier as part of the BBAS and AGASEA projects. It also includes basal reflectivity and one-way attenuation rates derived from these radargrams. Radar data from the Pine Island Ice Shelf inland to the Bentley Sublglacial Trench were collected by the British Antarctica Survey (BAS) with the Polarimetric-radar Airborne Science INstrument (PASIN) radar sounder, operating at a center frequency of 150 MHz and 15 MHz bandwidth. Data over Thwaites Glacier were collected by the University of Texas Institute for Geophysics (UTIG) High Capability Airborne Radar Sounder (HiCARS) operating at a center frequency of 60 MHz with 15 MHz of bandwidth. Data are provided as 50km segments in NetCDF files, along with kml location files, and pdf files for browsing radargrams images by flight transect. Details of the processing methods are included in the associated README file. The processed data sets (reflectivity and attenuation) are provided as a single NetCDF file for each flight transect. Details of the calibration and processing procedures are provided in Chu, et al (in review).
