Mass Loss of Greenland and Antarctic Peripheral Glaciers From ICESat and ICESat‐2 [PDF]

Journal of Geophysical Research: Earth Surface
Abstract Greenland and Antarctica's peripheral glaciers are an important but often overlooked element in the global sea‐level rise budget. Here, we use satellite laser altimetry from ICESat and ICESat‐2 to assess the mass loss from Greenland's and Antarctica's peripheral glaciers for three periods: February 2003 ...

ICE SHEET ELEVATION MAPPING AND CHANGE DETECTION WITH THE ICE, CLOUD AND LAND ELEVATION SATELLITE-2 [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
On September 15, 2018, ICESat-2 (Ice, Cloud, and land Elevation satellite) was successfully launched to measure ice sheet and glacier elevation change, sea ice freeboard, and vegetation.

On a possibility to use the remote sensing techniques for glaciological analysis in mountain regions of Uzbekistan

Лëд и снег, 2017
The ALOS/AVNIR-2 satellite data (2007–2010) allowed estimating areas of glaciers, change in the areas for 50 years, and the number and areas of new naturally-dammed lakes in the mountain regions of Uzbekistan. Boundaries of these gla‑ ciers together with

Improving ICESat‐2‐based boreal forest height estimation by a multivariate sample quality control approach

Methods in Ecology and Evolution, 2023
Boreal forest heights are associated with global carbon stocks and energy budgets. The launch of the Advanced Topographic Laser Altimeter System (ATLAS) onboard the NASA's Ice, Cloud and Land Elevation Satellite (ICESat‐2) enables canopy vertical ...

Leaf area index retrieval with ICESat-2 photon counting LiDAR

International Journal of Applied Earth Observations and Geoinformation, 2021
This is the first study to inverse leaf area index (LAI) with photon counting LiDAR (i.e., Ice, Cloud, and Land Elevation Satellite-2/Advanced Topographic Laser Altimeter System, ICESat-2/ATLAS). A new framework composed of three major steps was applied:

ICESat sea level comparisons [PDF]

Geophysical Research Letters, 2005
ICESat calculations of sea level and mesoscale variability are demonstrated and compared to calculations from TOPEX altimetry. In particular, we examine the accuracy of the ICESat Laser 2a Release 21 GLA15 ocean elevations. A global ICESat ocean elevation bias of −10.0 ± 1.0 cm (low) was found with respect to TOPEX, obtained with a reference mean sea ...

An Adaptive Filter Based on Local Slope by Adjusting Elliptic Filter Kernel for ICESat-2 Photon Counting Laser Altimetric Data [PDF]

EPJ Web of Conferences, 2020
The Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) was launched on September 15th, 2018, which continues to perform measurement tasks as the successor to ICESat. Unlike full waveform technology of ICESat, ICESat-2 employs micropulse photon counting

Aboveground biomass mapping by integrating ICESat-2, SENTINEL-1, SENTINEL-2, ALOS2/PALSAR2, and topographic information in Mediterranean forests

GIScience & Remote Sensing, 2022
The Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) provides an extraordinary opportunity to support global large-scale forest carbon mapping, but further research is needed in order to obtain wall-to-wall forest aboveground biomass (AGB) maps with

Estimating Terrain Slope from ICESat-2 Data in Forest Environments

Remote Sensing, 2020
The global digital elevation measurement (DEM) products such as SRTM DEM and GDEM have been widely used for terrain slope retrieval in forests. However, the slope estimation accuracy is generally limited due to the DEMs’ low vertical accuracy over ...

Accelerating High Mountain Asia Glacier Loss From ICESat and ICESat-2 [PDF]

IEEE Transactions on Geoscience and Remote Sensing
Communities dependent on snow and ice melt need to face escalating challenges due to glacier depletion, particularly in High Mountain Asia (HMA). Understanding glacier changes is thus crucial for addressing these impacts. Employing Ice, Cloud, and land Elevation Satellite (ICESat) and ICESat-2, we estimate glacier mass balance from 2003 to 2023 using ...
