Rapid Access and Visualization of Spaceborne Altimetry Data from ICESat and ICESat-2

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The goal of OpenAltimetry is to provide altimetry-specific data discovery and access with a focus on ease-of-use and quick response times. OpenAltimetry currently supports NASA's laser altimeter missions: ICESat (2003∼2009) and ICESat-2 (scheduled for launch in 2018) with a powerful, web-based interactive interface that provides data discovery ...

ICESat-2 laser technology development

SPIE Proceedings, 2013
A number of ICESat-2 system requirements drove the technology evolution and the system architecture for the laser transmitter Fibertek has developed for the mission.. These requirements include the laser wall plug efficiency, laser reliability, high PRF (10kHz), short-pulse (

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.

ICESat-2 ATLAS telescope testing

2015 IEEE Aerospace Conference, 2015
Many lessons were learned in the comprehensive testing of the one meter Beryllium flight telescope for the ICESat-2 mission. This paper will focus on testing areas of encircled energy analysis, plate scale measurements, and boresight alignment for alignment of fiber optic cables.

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 ...

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-2 altimetry for coastal MSS improvement

2023
Radar altimeters have traditioally been used for the determination of the mean sea surface to centimeter accuracy. However close to the coast the MSS degrade because of the lack of valid altimetry observations and because of the land contamination and the altimeter footprint size.
