Selection of the key earth observation sensors and platforms focusing on applications for Polar Regions in the scope of Copernicus system 2020-2030 [PDF]

open access: yes, 2019
An optimal payload selection conducted in the frame of the H2020 ONION project (id 687490) is presented based on the ability to cover the observation needs of the Copernicus system in the time period 2020–2030.

A new approach to estimate ice dynamic rates using satellite observations in East Antarctica [PDF]

open access: yesThe Cryosphere, 2017
Mass balance changes of the Antarctic ice sheet are of significant interest due to its sensitivity to climatic changes and its contribution to changes in global sea level. While regional climate models successfully estimate mass input due to snowfall,

Influence of Atmospheric Scattering on the Accuracy of Laser Altimetry of the GF-7 Satellite and Corrections

open access: yesRemote Sensing, 2021
Satellite laser altimetry can obtain sub-meter or even centimeter-scale surface elevation data over large areas, but it is inevitably affected by scattering caused by clouds, aerosols, and other atmospheric particles.

Sea level accelerations at globally distributed tide gauge stations during the satellite altimetry era

open access: yesJournal of Geodetic Science, 2018
This observational study reports that several globally distributed tide gauge stations exhibit a propensity of statistically significant sea level accelerations during the satellite altimetry era.

Can satellite altimetry observe coastally trapped waves on sub-monthly timescales? [PDF]

open access: yesOcean Science
Coastally trapped waves (CTWs) are a major cause of sub-seasonal coastal sea level variability. While they have mostly been studied using numerical models, observational evidence is limited due to the sparse spatial coverage of the tide gauge network and

Larval Transport Pathways Reveal Critical Habitat and Benefits of a Marine Protected Area to Fisheries

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.

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. As part of the Preparation for the Surface Water and Ocean Topography mission scheduled for launch in mid-2022, the present study aimed

Flood Risk Communications Through Maps: Challenges, Perception Theories and Approaches

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Flood risk communication is a core component of flood risk management, yet persistent challenges limit its effectiveness in supporting public understanding, preparedness and adaptive behaviour. Here, we examine flood risk maps as communication tools at the interface of scientific modelling, visual design, and human risk perception.

The Eddy Experiment: accurate GNSS-R ocean altimetry from low altitude aircraft

open access: yes, 2004
During the Eddy Experiment, two synchronous GPS receivers were flown at 1 km altitude to collect L1 signals and their reflections from the sea surface for assessment of altimetric precision and accuracy.
