David Bekaert is a Radar Scientist at the Radar Science and Engineering Section of the Jet Propulsion Laboratory, where he utilizes Interferometric Synthetic Aperture Radar (InSAR) processing techniques for Earth Science and Geoscience applications including natural hazards and critical infrastructure monitoring. Amongst many applications, time-series InSAR techniques can be used to generate land-based subsidence, one of the two components defining relative sea-level rise. As part of the NASA Sea Level Change Team he is analyzing long-duration SAR time-series to generate regional subsidence maps, helping to identify areas of high vulnerability where land subsidence can exceed the rate of sea-level rise.
The American Institute of Aeronautics and Astronautics (AIAA) is honoring Jet Propulsion Laboratory Director Watkins and Autonomous Systems Manager Gross, plus two European partners, for work on the GRACE missions.
So just how does the Surface Water and Ocean Topography (SWOT) mission expect to measure what’s flowing in the planet’s lakes, rivers, and oceans? A very busy project manager explains.
A new approach to simulations seamlessly combines multiple computer models for more fluid – and more precise – portraits of possible changes to come.
