Hydraulic Model Calibration Using CryoSat‐2 Observations in the Zambezi Catchment [PDF]
Water Resources Research, 2020 Abstract Geodetic altimeters provide unique observations of the river surface longitudinal profile due to their long repeat periods and densely spaced ground tracks. This information is valuable for calibrating hydraulic model parameters, and thus, for producing reliable simulations of water level for flood forecasting and river ...

Synthesis of the ICESat/ICESat-2 and CryoSat-2 observations to reconstruct time series of lake level
International Journal of Digital Earth, 2023 Synthesis of multi-satellite altimetry facilitates the acquisition of long-term changes in lake level but may induce biases due to inconsistent data sources, and thus remains largely unexplored.

Assessing CryoSat‐2 Antarctic Snow Freeboard Retrievals Using Data From ICESat‐2
Earth and Space Science, 2021 NASA's Ice, Cloud, and land Elevation Satellite‐2 (ICESat‐2) laser altimeter launched in Fall 2018, providing an invaluable addition to the polar altimetry record generated by ESA's CryoSat‐2 radar altimeter.

Retrieval of snow freeboard of Antarctic sea ice using waveform fitting of CryoSat-2 returns [PDF]
The Cryosphere, 2019 In this paper we develop a CryoSat-2 algorithm to retrieve the surface elevation of the air–snow interface over Antarctic sea ice. This algorithm utilizes a two-layer physical model that accounts for scattering from a snow layer atop sea ice as well as ...

IEEE 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.

Monitoring Arctic thin ice: a comparison between CryoSat-2 SAR altimetry data and MODIS thermal-infrared imagery [PDF]
The Cryosphere, 2023 Areas of thin sea ice in the polar regions not only are experiencing the highest rate of sea-ice production but also are, therefore, important hot spots for ocean ventilation as well as heat and moisture exchange between the ocean and the atmosphere ...

Classification of CryoSat-2 Radar Echoes [PDF]
, 2015 Sea-ice thickness at global scale is an important variable in the polar climate system. Only satellite altimeters such as onboard the CryoSat-2 mission allow us to obtain sea-ice thickness on hemispherical scale. Accurate CryoSat-2 altimeter range measurements provide surface elevations which have to be referenced to the local sea level to obtain sea ...

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

Wet tropospheric correction for satellite altimetry using SIRGAS-CON products
Journal 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
