CryoSat-2 Ocean Altimetry Assessment
2016CryoSat-2 was launched April 2010 and has been monitoring the Earth’s cryosphere and oceans since with unprecedented accuracy and precision by an ice-dedicated altimeter capable of measuring in LRM, SAR and SARin mode. In this paper we validate CryoSat-2 LRM, RDSAR, IOP and GOP ocean data and assess their quality in comparison with other altimeters by ...

CryoSat-2 Ocean Altimetry Assessment
2017CryoSat-2 was launched on the 8th of April 2010, the primary purpose of the mission is to measure sea ice thickness, however the mission is also able to monitor land ice volume variations and ocean height changes. The primary instrument is the Siral altimeter, it comes with an unprecedented accuracy and precision capable of measuring in a low ...

Point-to-point ICESat-2 vs CryoSat-2 comparison
2021<p>For measuring the mass balance of mountain glaciers, the combination of ICESat-2 and CryoSat-2 data holds the potential to improve both spatial and temporal coverage and measurement quality. Both satellite missions are dedicated to measuring the surface elevation in the cryosphere and complement each other.

Precision orbit determination performance for CryoSat-2
Advances in Space Research, 2018Abstract In this paper we discuss our efforts to perform precision orbit determination (POD) of CryoSat-2 which depends on Doppler and satellite laser ranging tracking data. A dynamic orbit model is set-up and the residuals between the model and the tracking data is evaluated. The average r.m.s. of the 10 s averaged Doppler tracking pass residuals is

Validation of CryoSat-2 SAR mode based lake levels
Remote Sensing of Environment, 2015Lake level serve as an important indicator of the climate and continuous measurements are therefore essential. Satellite radar altimetry has now been used successfully for more than two decades to measure lake level as an addition to gauge measurements.

Cryosat-2 altimetry of BC Coastal Mountain glaciers
Remote Sensing Letters, 2016ABSTRACTCryosat-2 altimetry, for the period July 2010 to January 2016, shows widespread melting of glaciers in the southern part of the British Columbia (BC) Coastal Mountain range in western Canada. The Interferometric Radar Altimeter on Cryosat-2 is in synthetic aperture mode in this area, recording elevations of suitably-sloping targets out to about

Improvement of a radiation model for Cryosat-2
2014In this paper we discuss the precision orbit modeling of Cryosat-2 launched on 8-April-2010 to map the cryosphere with an advanced radar altimeter system. The satellite is tracked with laser and DORIS for which we find residuals of 1.58 cm and 0.4 mm/sec respectively.
