Abstract: With the global population surpassing 7.8 billion people in 2021, the impacts of human activities on the environment are noticeable almost everywhere on our planet. The consequences of these impacts are still elusive, particularly when trying to quantify them at larger scales. It is essential to trace environmental changes from a local to a global scale over several decades. This task is increasingly fulfilled by Earth-observing (EO) satellites, in particular, radar imaging instruments. Synthetic Aperture Radar (SAR), a cloud-penetrant microwave imaging system, provides unique day-night and all-weather monitoring capabilities. The availability of repeated SAR acquisitions with similar imaging geometry allows performing interferometric SAR (InSAR) processing. InSAR uses radar to illuminate an area of the Earth's surface and measures the change in distance between satellite and ground surface, as well as the returned signal strength. Such measurements are suitable for generating high-resolution digital elevation models and accurate terrain deformation maps. Firstly, I will discuss some of the recent advances in modern multitemporal InSAR algorithms. Next, I will present examples demonstrating the value of high-resolution Radar EO satellite data for mapping surface deformation and change monitoring with implications for relative sea-level rise and flooding hazards. These sets of case studies highlight the importance of EO satellite data for developing management, adaptation, and resilience plans.
