On 13 March 2017, the NASA IceBridge HiCARS 1 L2 Geolocated Ice Thickness data were replaced. The data files now include extensive header information, including field descriptions, campaign information, and data processing notes. XML metadata files are now included with the data set. This data set contains ice thickness, surface and bed elevation, and echo strength measurements taken over Antarctica using the Hi-Capability Airborne Radar Sounder (HiCARS) instrument.
