Analysis of ICESat‐2 Data Acquisition Algorithm Parameter Enhancements to Improve Worldwide Bathymetric Coverage

open access: yesEarth and Space Science
A major advance in global bathymetric observation occurred in 2018 with the launch of NASA’s ICESat‐2 satellite, carrying a green‐wavelength, photon‐counting lidar, the Advanced Topographic Laser Altimeter System (ATLAS). Although bathymetric measurement

Quantifying Volumetric Scattering Bias in ICESat‐2 and Operation IceBridge Altimetry Over Greenland Firn and Aged Snow

open access: yesEarth and Space Science
The Ice, Cloud, and Land Elevation Satellite‐2 (ICESat‐2) mission has collected surface elevation measurements for over 5 years. ICESat‐2 carries an instrument that emits laser light at 532 nm, and ice and snow absorb weakly at this wavelength.

Creation of ICESat-2 Footprint Level Global Geodetic Control Points Using Crossover Analysis

open access: yesRemote Sensing
Precise measurements of the Earth’s surface are possible using satellite laser altimetry data, as demonstrated by NASA’s ICEsat-2 mission. Recently, the vertical accuracy of ICESat-2 data has been validated to

Characterizing ICESat‐2 Snow Depths Over the Boreal Forests and Tundra of Alaska in Support of the SnowEx 2023 Campaign

open access: yesWater Resources Research
Recent studies show that the Ice, Clouds, and Land Elevation Satellite‐2 (ICESat‐2) can achieve decimeter‐level accuracy over forested and mountainous sites in the western United States, as well as over the glaciers of Alaska.

Assessing Vertical Accuracy and Spatial Coverage of ICESat-2 and GEDI Spaceborne Lidar for Creating Global Terrain Models

open access: yesRemote Sensing
Digital Elevation Models (DEMs) are a necessity for modelling many large-scale environmental processes. In this study, we investigate the potential of data from two spaceborne lidar altimetry missions, ICESat-2 and GEDI—with respect to their vertical ...

Substantial potential of ICESat-2 photon-counting laser altimetry for reconstructing the lake water depth on the Tibetan Plateau

open access: yesInternational Journal of Digital Earth
The littoral zone is crucial in the aquatic ecosystem of lakes, and water depth is often insufficient when using the traditional zigzag echo-sounding method.

The Vital Role of ICESat Data Products

open access: yes, 2011
Changes in Ice sheet thicknesses, sea level, and sea ice extent have been explicitly identified as a current priority in the President’s Climate Change Science Program, the Arctic Climate Impact Assessment, the 4th Assessment Report of the IPCC and other

TanDEM-X: Block adjustment of interferometric height models [PDF]

open access: yes, 2009
The TanDEM-X mission will derive a global digital elevation model (DEM) with satellite SAR interferometry. The aimed accuracies are an absolute, resp. relative height error of 10m resp. 2m for 90% of the data.
