Merging Recent Mean Sea Surface Into a 2023 Hybrid Model (From Scripps, DTU, CLS, and CNES)
EARTH AND SPACE SCIENCE
07 february 2025
Alice Laloue, Philippe Schaeffer, Marie-Isabelle P...
In this paper, we compute a new hybrid mean sea surface (MSS) model by merging three recent models, CNES_CLS22, SCRIPPS_CLS22, and DTU21, and takin...
Estimating Earthquake Ground Acceleration using InSAR Coherence and Topographic Gradient
RECENT ADVANCES IN SAR AND INSAR PROCESSING, BIG DATA ANALYSIS, AND EARTH SCIENCE APPLICATIONS III POSTER
geodesy | 12 december 2024
Matthew Brandin, David T. Sandwell
We explore the potential for using InSAR coherence to estimate earthquake ground acceleration in hilly and sloped terrain. We use simple Newmark slidi...
