Abstract:
Airborne radar data collected during the PolarGap project funded by the European Space Agency. The radar system PASIN of the British Antarctic Survey was used for data collection.
Quality
Data were collected in December 2015 in a 10 km grid above the Recovery Lakes A, B and C. The data files include Latitude, Longitude, x and y coordinates (Antarctic Polar Stereographic projection, true scale at -71°, EPSG3031), air plane elevation, ice sheet surface elevation (derived from LIDAR data), bed elevation, ice thickness and uncorrected relative bed return power. Elevations are given in relation to the WGS84 ellipsoid. Bed returned power in all three files are referenced to a single, common refernece level.
Profile P07 and P10: Data collected above the Recovery Lakes A and B. Profile P11: Data collected above the Recovery Lake C.
The PolarGAP project collected many other flight data south of 83S. Data from those flights are released from ESA’s data portal and UK’s Polar Data Centere.
