ARIA

Overview

ARIA is a collaboration between JPL and Caltech to exploit radar and optical remote sensing, GPS, and seismic observations for hazard science and response.  

ARIA investigates the processes and impacts of earthquakes, volcanoes, landslides, fires, subsurface fluid movement and other natural hazards by applying modern geodesy, merged with ground-based observations, to improve society's resilience.  ARIA develops state-of-the-art ground deformation measurements, change detection methods and physical models using GPS and synthetic aperture radar observations, automating the required large scale processing, and producing basic data products for the science community.

Disasters Capabilities:

  • Data from various Synthetic Aperture Radar (SAR) instruments is processed by the ARIA team to produce interferograms and surface deformation maps to support response and recovery from earthquakes and volcanoes. 
  • Data from various SAR nstruments is processed by the ARIA team to produce damage proxy maps which identify damaged infrastructure to support response and recovery from earthquakes, volcanoes, and tropical cyclones. 
  • Data from various SAR nstruments is processed by the ARIA team to produce flood proxy maps which identify water extent and flooded areas to support response and recovery from floods and tropical cyclones.
