Satellite radar altimetry for monitoring small rivers and lakes in Indonesia [PDF]

open access: yesHydrology and Earth System Sciences, 2015
Remote sensing and satellite geodetic observations are capable of hydrologic monitoring of freshwater resources. Although satellite radar altimetry has been used in monitoring water level or discharge, its use is often limited to monitoring large rivers (

Time-evolving mass loss of the Greenland Ice Sheet from satellite altimetry [PDF]

open access: yesThe Cryosphere, 2014
Mass changes of the Greenland Ice Sheet may be estimated by the input–output method (IOM), satellite gravimetry, or via surface elevation change rates (dH/dt).

Combining satellite radar altimetry, SAR surface soil moisture and GRACE total storage changes for hydrological model calibration in a large poorly gauged catchment [PDF]

open access: yesHydrology and Earth System Sciences, 2011
The availability of data is a major challenge for hydrological modelling in large parts of the world. Remote sensing data can be exploited to improve models of ungauged or poorly gauged catchments.

Quality analysis of water level series obtained by altimetric radar satellite along the São Francisco River

open access: yesRBRH, 2021
Radar altimeters are instruments carried on space missions and allow for determination of heights, particularly in oceans and ice sheets. The use of altimetry data on continental waters involves several challenges, such as the revisit frequency ...

Real-time remote sensing driven river basin modeling using radar altimetry [PDF]

open access: yesHydrology and Earth System Sciences, 2011
Many river basins have a weak in-situ hydrometeorological monitoring infrastructure. However, water resources practitioners depend on reliable hydrological models for management purposes. Remote sensing (RS) data have been recognized as an alternative to

Radar altimetry for the detection of ship traffic: an improved byproduct of satellite radar altimetry

open access: yes, 2023
The detection of vessels is considered an attractive byproduct of satellite radar altimetry, because it may complement the conventional tracking systems with the possibility to build long-term global statistics of ship traffic based on relatively small and manageable datasets of freely available data.

Satellite altimetry for Indian reservoirs

open access: yesWater Science and Engineering, 2021
Satellite radar altimetry has immense potential for monitoring fresh surface water resources and predicting the intra-seasonal, seasonal, and inter-annual variability of inundated surface water over large river basins.

River ice phenology and thickness from satellite altimetry: potential for ice bridge road operation and climate studies [PDF]

open access: yesThe Cryosphere, 2021
River ice is a key component of the cryosphere. Satellite monitoring of river ice is a rapidly developing area of scientific enquiry, which has wide-ranging implications for climate, environmental and socioeconomic applications.

Arctic sea ice radar freeboard retrieval from the European Remote-Sensing Satellite (ERS-2) using altimetry: toward sea ice thickness observation from 1995 to 2021

open access: yesThe Cryosphere, 2023
. Sea ice volume's significant interannual variability requires long-term series of observations to identify trends in its evolution. Despite improvements in sea ice thickness estimations from altimetry during the past few years thanks to CryoSat-2 and ...

Automatic Detection of Inland Water Bodies along Altimetry Tracks for Estimating Surface Water Storage Variations in the Congo Basin

open access: yesRemote Sensing, 2021
Surface water storage in floodplains and wetlands is poorly known from regional to global scales, in spite of its importance in the hydrological and the carbon balances, as the wet areas are an important water compartment which delays water transfer ...
