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 (

High-resolution airborne observations of sea-ice pressure ridge sail height

open access: yesAnnals of Glaciology, 2018
Pressure ridges impact the mass, energy and momentum budgets of the sea-ice cover and present an obstacle to transportation through ice-infested waters. Quantifying ridge characteristics is important for understanding total sea-ice mass and for improving
