Water level analysis in Tibet using CryoSat-2

, 2019
While the water level monitoring inTibet suffers data gaps due to insufficient in situ gauge stations, the satellite altimetry serves as an efficient alternative. In this work, measurements from the CryoSat-2 mission are employed and analyzed to determine water level time series in various lakes throughout Tibetan region. The time series are calculated

Assimilating Summer Sea‐Ice Thickness Observations Improves Arctic Sea‐Ice Forecast

Geophysical Research Letters
Accurate Arctic sea‐ice forecasting for the melt season is still a major challenge because of the lack of reliable pan‐Arctic summer sea‐ice thickness (SIT) data.

Lead and Floe Detection From CryoSat‐2 Radar and ICESat‐2 Laser Altimetry

Earth and Space Science
Differences in satellite sampling affect their ability to resolve small‐scale features over Arctic sea ice. For CryoSat‐2 (CS2) and ICESat‐2 (IS2) these differences are driven by geometric (footprint resolution) and radiometric (radar or laser) sampling.

Analysis of the Influence of Different Reference Models on Recovering Gravity Anomalies from Satellite Altimetry

Remote Sensing
A satellite altimetry mission can measure high-precision sea surface height (SSH) to recover a marine gravity field. The reference gravity field model plays an important role in this recovery.

Two Decades of Arctic Sea-Ice Thickness from Satellite Altimeters: Retrieval Approaches and Record of Changes (2003–2023)

Remote Sensing
There now exists two decades of basin-wide coverage of Arctic sea ice from three dedicated polar-orbiting altimetry missions (ICESat, CryoSat-2, and ICESat-2) launched by NASA and ESA.

The ESA Permanent Facility for Altimetry Calibration in Crete: Advanced Services and the Latest Cal/Val Results

Remote Sensing
Two microwave transponders have been operating in west Crete and Gavdos to calibrate international satellite radar altimeters at the Ku-band. One has been continuously operating for about 8 years at the CDN1 Cal/Val site in the mountains of Crete, and ...
