It describes specific aspects of the altimetry technique applied for studying land ice and discusses specifics of measurements of polar ice sheets by radar altimeters.

It summarizes average characteristics of the ice sheet, assuming in first approximation that it is in a state of mass balance. Surface topography is one of the most pertinent parameters for monitoring an ice sheet but also for constraining ice flow models. When using altimetric series, the error due to the poor temporal repetition of the satellite ground track and the presence of surface slope must be corrected.
