    Tracking mountainous glaciers using TanDEM-X

    Ice melting from mountain glaciers is one of the largest contributors to sea-level rise outside the large ice sheets of Antarctica and Greenland. New research leveraging the vast data from the TanDEM-X mission, has successfully mapped glacial elevation change over multiple mountainous regions of the world.

    Towards More Efficient Use of Radar-Altimeter Data

    Twenty years ago, experimental altimeters on NASA's Skylab and Geos-3 were already demonstrating the potential of such instrumentation. This led in turn to the development and launch by NASA in July 1978 of the Seasat oceanographic satellite mission. Both Geos-3 and Seasat were very successful in their pioneering missions, but were limited somewhat by poor coverage in the case of Geos-3 and an abnormally short mission duration in Seasat's case.

    Toolbox Functionality and Algorithm Specification Document - GOCE User Toolbox Specifications (GUTS)

    Deliverable: WP3000: This report is the output from WP3000 of the GOCE User Toolbox Specification. The study will select the best (in terms of accuracy and computational demands) algorithms to compute the variables listed in the user requirement document [1]. This document will form the basis for the system specification work performed in WP4000 and the prototype and tutorials to be generated in WP5000, all available in this library.
