524 NASA Data Made Easy: Getting Started with Synthetic Aperture Radar
NASA’s airborne- and satellite-based instruments provide information for understanding a number of natural disasters, including flooding, cyclonic storms, earthquakes, and landslides. However, during disasters, conditions are often not ideal for making observations using optical sensors. Synthetic aperture radar, or SAR, which uses the microwave region of the electromagnetic spectrum, is ideal in that it can penetrate cloud cover and “see through” darkness and weather, allowing a unique view of flood inundation, land cover changes, and changes in Earth’s surface from earthquakes and landslides. NASA data are free and open but can be challenging to use. NASA’s Earth Science Data Systems (ESDS) program and Distributed Active Archive Centers (DAACs) have developed resources and tools to overcome this challenge. The ESDS has developed a disaster data pathfinder that links to SAR datasets commonly used for disaster monitoring and assessment; the Alaska Satellite Facility (ASF) DAAC has a number of tools for accessing, processing, and analyzing SAR data; and GeoGateway provides tools for scientific discovery, field use, and disaster response using Interferometric SAR (InSAR) and GPS integrated with earthquake fault, seismicity, and model data. In this workshop, we will demonstrate these resources for geologists wishing to get started using NASA SAR data.
