Statement

Methodology:

The swath elevation data are produced from CryoSat-2 as described in the following paper:

Gourmelen, N, Escorihuela, M, Shepherd, A, Foresta, L, Muir, A, Garcia-Mondejar, A, Roca, M, Baker, S & Drinkwater, MR 2017, 'CryoSat-2 swath interferometric altimetry for mapping ice elevation and elevation change' Advances in Space Research. DOI: 10.1016/j.asr.2017.11.014

Data collection:

CryoSat-2 spaceborne interferometric radar altimeter.

Data quality:

There is a minimal amount of editing of the data as to provide maximum flexibility. The user should therefore use caution, as the dataset will contain measurements of variable quality. The user should make use of the quality estimator provided, e.g. signal coherence and signal power. A typical minimum value of coherence is 0.8 and a typical minimum value of power is -170. It is also recommended to the user to check for remaining errors using a reference DEM (e.g. Bedmap2, REMA, TanDEM-X) as to identify remaining data blunders that would originate from sensor or processing errors. Details of data quality, potential issues, and validations can be found in Gourmelen et al., 2017 and in literature listed here.
