Assessment of CryoSat-2 Baseline-D Height Product by GNSS and ICESat-2 in Lambert-Amery System, East Antarctica

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
CryoSat-2 repeatedly collects dense radar altimetry footprints covering high latitudes of the polar ice sheets for over ten years. The Baseline-D height product of CryoSat-2 was recently upgraded and released in 2019.

Ice-sheet elevations from across-track processing of airborne interferometric radar altimetry [PDF]

open access: yes, 2009
Interferometric Radar Altimeters (IRA's) use dual receive antennas to overcome one of the spatial limitations of pulse-limited altimeters. In a conventional IRA measurement, the range and across-track direction of a scatterer are determined using the ...

CryoSat-2 Sea-Ice Freeboard and Thickness [PDF]

open access: yes, 2013
The understanding and predictability of the observed decline of Arctic sea ice depends on the knowledge of its mass balance in a warming environment. While sea ice extent is monitored by passive microwave sensors for decades, only recently its volume is ...

Wet tropospheric correction for satellite altimetry using SIRGAS-CON products

open access: yesJournal of Geodetic Science, 2022
The wet tropospheric correction (WTC) is a required correction to satellite altimetry measurements, mainly due to the atmospheric water vapor delay. On-board microwave radiometers (MWR) provide information for WTC estimation but fail in coastal zones and

Improving the Arctic Mean Sea Surface with CryoSat-2 Data [PDF]

open access: yes, 2013
A fundamental basis for estimating short and long-term changes in the sea surface is a reliable mean sea surface (MSS). Existing MSS models, derived from satellite radar altimetry, generally lack observations above 82 degrees latitude making high Arctic sea surface change estimates unreliable.

Polar Ocean dataset (Cryosat-2)

open access: yes, 2023
Arctic and Antarctic Cryosat-2 Polar datasetThe files contain the Cryosat-2 sea surface height data for the Arctic and Antarctic regions for the period 2010.5 until 2019.12.Data can be used to study ocean tides or sea level variations. The data have been

A new Arctic MSS model derived from combined Cryosat-2 and ICESat observations

open access: yesInternational Journal of Digital Earth, 2022
Due to the existence of seasonal or perennial sea ice cover, the determination of the Arctic sea surface is more difficult than that of mid-low latitudinal oceans.

CryoSat-2 Antarctic Snow Freeboard Estimates

open access: yes, 2021
Along-track and gridded estimates of Antarctic snow freeboard derived from CryoSat-2 Baseline-D SAR and SARIn data from October 2018 through October 2020. Data are generated using a physical retracker and waveform-fitting method.

Comparison of CryoSat-2 and ENVISAT radar freeboard over Arctic sea ice: toward an improved Envisat freeboard retrieval [PDF]

open access: yesThe Cryosphere, 2017
Over the past decade, sea-ice freeboard has been monitored with various satellite altimetric missions with the aim of producing long-term time series of ice thickness.

Improved retrieval of land ice topography from CryoSat-2 data and its impact for volume-change estimation of the Greenland Ice Sheet [PDF]

open access: yesThe Cryosphere, 2016
A new methodology for retrieval of glacier and ice sheet elevations and elevation changes from CryoSat-2 data is presented. Surface elevations and elevation changes determined using this approach show significant improvements over ESA's publicly ...
