Determination of Long-Term (1993–2019) Sea Level Rise Trends Around the Korean Peninsula Using Ocean Tide-Corrected, Multi-Mission Satellite Altimetry Data

Frontiers in Marine Science, 2022
It is vital to improve estimations of long-term trends in global and regional sea level rise to help mitigate and adapt to climate change. Satellite altimetry data have been widely used for this purpose; however, data collected in regions with strong ...

Sea level change along the Black Sea coast from satellite altimetry, tide gauge and GPS observations

Geodesy and Geodynamics, 2016
Sea level change affects human living conditions, particularly ocean coasts. However, sea level change is still unclear along the Black Sea coast due to lack of in-situ measurements and low resolution satellite data. In this paper, sea level change along

Observing and Modelling the HighWater Level from Satellite Radar Altimetry During Tropical Cyclones

, 2015
This paper investigates the capability of observing tropical cyclones using satellite radar altimetry. Two representative cyclones Yasi (February 2011) and Larry (March 2006) in the northeast Australian coastal area are selected based also on available ...

Definition of ICESat Selection Criteria for their Use as Height References for TanDEM-X

, 2010
The TanDEM X satellite synthetic aperture radar (SAR) mission has the goal to deliver a high-precision global digital elevation model (DEM). The X band SAR interferometry (InSAR)-derived DEMs contain absolute and relative height errors that have to be ...

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

The 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,

A first approach towards dual-hemisphere sea ice reference measurements from multiple data sources repurposed for evaluation and product intercomparison of satellite altimetry [PDF]

Earth System Science Data
Sea ice altimetry currently remains the primary method for estimating sea ice thickness from space, however, time series of such satellite-derived estimates are of limited use without having been quality-controlled against reference measurements.
