A New Web-Based Software Tool for ICESat and ICESat-2 Laser Altimetry Data Processing and Visualization

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The purpose of this paper is to present and briefly describe a web-based tool for processing and visualizing in a suitable way the available data from satellite laser altimetry missions, in particular data from ICESat and ICESat-2. This new tool, called ICEComb, allows to access all data contained within each data granule of the datasets of both ...

Tibetan Plateau's Lake Level and Volume Changes From NASA's ICESat/ICESat‐2 and Landsat Missions

Geophysical Research Letters, 2019
AbstractLake level change is an effective indicator of climate change, because it reflects the dynamic balance of water input and loss. Here we provide a first look of Ice, Cloud, and land Elevation Satellite‐2 (ICESat‐2) on the lakes of the Tibetan Plateau. ICESat‐2 doubles the number of lakes observed using predecessor ICESat data.

The ICESat-2 Laser Altimetry Mission

Proceedings of the IEEE, 2010
Satellite and aircraft observations have revealed that remarkable changes in the Earth's polar ice cover have occurred in the last decade. The impacts of these changes, which include dramatic ice loss from ice sheets and rapid declines in Arctic sea ice, could be quite large in terms of sea level rise and global climate.

A design on calibration and validation of ICESat data

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
The accurate geolocation (horizontal and vertical position) of a laser altimeter's surface returns (the spots from which the laser energy reflects on the earth's surface) is a critical issue in the scientific application of these data. The geolocation of laser surface return is computed from the laser-altimeter surface range observations along with the

Operation icebridge: Using instrumented aircraft to bridge the observational gap between icesat and icesat-2

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
Operation IceBridge, a six-year NASA mission, is the largest airborne survey of Earth's polar ice ever flown. Data collected during IceBridge will help scientists bridge the gap in polar observations between NASA's Ice, Cloud and Land Elevation Satellite (ICESat), in orbit from 2003 to 2009, and ICESat-2, planned for launch in late 2015, making ...

ICESat Geolocation Validation Using Airborne Photography

IEEE Transactions on Geoscience and Remote Sensing, 2010
NASA's ICESat satellite launched in January of 2003, carrying the Geoscience Laser Altimeter. During the initial phase of this mission, many validation procedures were implemented to verify the accuracy associated with a variety of altimetry-derived data products.

ICESat GLAS Data for Urban Environment Monitoring

IEEE Transactions on Geoscience and Remote Sensing, 2011
Although the Geoscience Laser Altimeter System (GLAS) onboard the NASA Ice, Cloud and Land Elevation Satellite was not designed for urban applications, its 3-D measurement capability over the globe makes it a nice feature for consideration in monitoring urban heights. However, this has not been previously done. In this paper, we report some preliminary

Surface-Water-Level Changes During 2003–2019 in Australia Revealed by ICESat/ICESat-2 Altimetry and Landsat Imagery

IEEE Geoscience and Remote Sensing Letters, 2021
Surface-water-level changes reflect Earth’s water resource variations ( e.g. , trends and fluctuations) and they are helpful to understand potential drivers ( e.g. , climate change and human activities). Currently, Australia is facing serious water crisis owing to rainfall shortage and climate change, and national-scale data set on surface-water-level ...

A Two-Stage Approach for Decomposition of ICESat Waveforms

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Decomposing a waveform into distinct components by fitting a mixture of Gaussians impacts the ultimate interpretation of the return waveform, because the resulting parameter estimates of the Gaussian mixture directly affect the understanding of vertical structure within laser footprints. Decomposing the waveform into a mixture of Gaussians involves two

ICESat-2 laser Nd:YVO4 amplifier

Components and Packaging for Laser Systems IV, 2018
We report on the cause and corrective actions of three amplifier crystal fractures in the space-qualified laser systems used in NASA Goddard Space Flight Center’s (GSFC) Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2). The ICESat-2 lasers each contain three end-pumped Nd:YVOO4 amplifier stages.
