Description

This data set contains glacier surface elevation, bed elevation, and ice thickness measurements 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 taken from IceBridge ARES L1B Geolocated Radar Echo Strength Profiles (IRARES1B).
