Performance of ICESat‐2 Precision Pointing Determination
Earth and Space Science, 2021 Global elevations are critical to understanding the Earth's dynamic processes and changing climate. These measurements are best acquired from a space‐based vantage point and are most accurate using laser altimetry technology.

On the retrieval of sea ice thickness and snow depth using concurrent laser altimetry and L-band remote sensing data [PDF]
The Cryosphere, 2018 The accurate knowledge of sea ice parameters, including sea ice thickness and snow depth over the sea ice cover, is key to both climate studies and data assimilation in operational forecasts.

Rapid submarine ice melting in the grounding zones of ice shelves in West Antarctica. [PDF]
, 2016 Enhanced submarine ice-shelf melting strongly controls ice loss in the Amundsen Sea embayment (ASE) of West Antarctica, but its magnitude is not well known in the critical grounding zones of the ASE's major glaciers.

Time-evolving mass loss of the Greenland Ice Sheet from satellite altimetry [PDF]
The Cryosphere, 2014 Mass changes of the Greenland Ice Sheet may be estimated by the input–output method (IOM), satellite gravimetry, or via surface elevation change rates (dH/dt).
