Evaluation of the Performances of Radar and Lidar Altimetry Missions for Water Level Retrievals in Mountainous Environment: The Case of the Swiss Lakes

open access: yesRemote Sensing, 2021
Radar altimetry is now commonly used to provide long-term monitoring of inland water levels in complement to or for replacing disappearing in situ networks of gauge stations.

Niger discharge from radar altimetry: bridging gaps between gauge and altimetry time series [PDF]

open access: yesHydrology and Earth System Sciences, 2019
The Niger River represents a challenging target for deriving discharge from spaceborne radar altimeter measurements, particularly since most terrestrial gauges ceased to provide data during the 2000s. Here, we propose deriving altimetric rating curves by

Global coastal attenuation of wind-waves observed with radar altimetry [PDF]

open access: yesNat Commun, 2021
Coastal studies of wave climate and evaluations of wave energy resources are mainly regional and based on the use of computationally very expensive models or a network of in-situ data.

Research on Radio Altimetry in Urban Environments Based on Electromagnetic Simulation Echo Modeling Technology [PDF]

open access: yesSensors
As the low-altitude economy develops rapidly, precise radar altimetry is crucial for ensuring the safety and reliability of drone flights. In the context of urban radio detection, the presence of numerous buildings and ground surfaces gives rise to ...

Antarctic Ice Sheet and Radar Altimetry: A Review [PDF]

open access: yesRemote Sensing, 2009
Altimetry is probably one of the most powerful tools for ice sheet observation. Our vision of the Antarctic ice sheet has been deeply transformed since the launch of the ERS1 satellite in 1991. With the launch of ERS2 and Envisat, the series of altimetric observations now provides 19 years of continuous and homogeneous observations that allow ...

Greenland Ice Sheet surface roughness from Ku- and Ka-band radar altimetry surface echo strengths [PDF]

open access: yesThe Cryosphere
Surface roughness is an important factor to consider when modelling mass changes at the Greenland Ice Sheet (GrIS) surface (i.e., surface mass balance, SMB).

Greenland Ice Sheet Mass Balance (1992–2020) From Calibrated Radar Altimetry

open access: yesGeophysical Research Letters, 2021
We present the first 1992–2020 record of Greenland Ice Sheet (GrIS) mass balance derived from multisatellite Ku‐band altimetry. We employ an empirical approach as an alternative detailed to radar‐propagation modeling, and instead convert elevation ...

Estimation of Arctic Sea Ice Thickness from Chinese HY-2B Radar Altimetry Data

open access: yesRemote Sensing, 2023
Sea ice thickness (SIT) is an important parameter in the study of climate change. During the past 20 years, satellite altimetry has been widely used to observe sea ice thickness.

Arctic Ocean Sea Level Record from the Complete Radar Altimetry Era: 1991–2018

open access: yesRemote Sensing, 2019
In recent years, there has been a large focus on the Arctic due to the rapid changes of the region. Arctic sea level determination is challenging due to the seasonal to permanent sea-ice cover, lack of regional coverage of satellites, satellite ...

Elevation Changes of the Antarctic Ice Sheet from Joint Envisat and CryoSat-2 Radar Altimetry

open access: yesRemote Sensing, 2020
The elevation changes of ice sheets have been recognized as an essential climate variable. Long-term time series of these changes are an important parameter to understand climate change, and the longest time-series of ice sheet elevation changes can be ...
