Calibration and validation experiments conducted for the CryoSat2 campaign have begun to address this issue by collecting concurrent ground-based and airborne measurements of ice surface elevation, along with detailed measurements of the physical properties and stratigraphy of near-surface snow and firn, which can be used to investigate the causes of differences in measurements of surface elevation made using GPS, laser altimetry, and radar altimetry.
