Hydraulic Model Calibration Using CryoSat‐2 Observations in the Zambezi Catchment [PDF]

open access: yesWater 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 ...

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.

The performance and potentials of the CryoSat-2 SAR and SARIn modes for lake level estimation [PDF]

open access: yes, 2017
Over the last few decades, satellite altimetry has proven to be valuable for monitoring lake levels. With the new generation of altimetry missions, CryoSat-2 and Sentinel-3, which operate in Synthetic Aperture Radar (SAR) and SAR Interferometric (SARIn ...

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

Classification of CryoSat-2 Radar Echoes [PDF]

open access: yes, 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 ...

CryoSat-2 Altimetry Applications over Rivers and Lakes [PDF]

open access: yesWater, 2017
Monitoring the variation of rivers and lakes is of great importance. Satellite radar altimetry is a promising technology to do this on a regional to global scale. Satellite radar altimetry data has been used successfully to observe water levels in lakes and (large) rivers, and has also been combined with hydrologic/hydrodynamic models. Except CryoSat-2,

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.

Application of CryoSat-2 altimetry data for river analysis and modelling [PDF]

open access: yes, 2017
Availability of in situ river monitoring data, especially of data shared across boundaries, is decreasing, despite growing challenges for water resource management across the entire globe.

Antarctic grounding zone characteristics from CryoSat-2 [PDF]

open access: yes, 2019
Abstract. We present the results of mapping the limit of tidal flexure (point F) and hydrostatic equilibrium (point H) of the grounding zone of Antarctic ice shelves from CryoSat-2 standard and swath elevation data. Overall we were able to map 41 % of the grounding zone of the larger floating ice shelves and outlet glaciers in Antarctica.

A high resolution record of Greenland mass balance [PDF]

open access: yes, 2016
We map recent Greenland Ice Sheet elevation change at high spatial (5-km) and temporal (monthly) resolution using CryoSat-2 altimetry. After correcting for the impact of changing snowpack properties associated with unprecedented surface melting in 2012 ...
