Description

This data set contains measurements of glacier surface elevation, bed elevation, and ice thickness for Alaska and Northwestern Canada. Glacier surface elevation is derived from IceBridge UAF Lidar Scanner L1B Geolocated Surface Elevation Triplets (ILAKS1B). Radar bed returns are sourced from IceBridge UAF L1B HF Geolocated Radar Echo Strength Profiles (IRUAFHF1B) to provide glacier bed elevation and ice thickness. Radar-derived ice thickness and glacier bed elevation are provided as per-trace measurements from the corresponding L1B radar echo strength profile (referencing the WGS 84 ellipsoid).
