Abstract:
Looking Into the Continents from Space with Synthetic Aperture Radar (LiCSAR) is a system built for large-scale interferometric processing of Sentinel-1 data. LiCSAR automatically produces geocoded wrapped and unwrapped interferograms combining every acquisition epoch with four preceding epochs, and complementary data (e.g. data from Generic Atmospheric Correction Online Service, GACOS).

The LiCSAR products are generated in frame units where a standard frame covers ~220x250 km, at 0.001° resolution (WGS-84 coordinate system). Frames are continuously updated for tectonic and volcanic priority areas. In 2020, the LiCSAR system covered about 1,600 global frames in which we have processed over 90,000 Sentinel-1 acquisitions and generated over 350,000 interferograms. Among these, 470 frames cover 1,024 global volcanoes.

Our products can be directly converted to displacement time series and velocities using the LiCSBAS time series analysis software: https://github.com/yumorishita/LiCSBAS. LiCSBAS currently uses (and automatically downloads) unwrapped data and GACOS corrections where available. The combination of LiCSAR products and LiCSBAS processor is applied in COMET Volcano Portal: https://comet.nerc.ac.uk/comet-volcano-portal.

We present solutions implemented in LiCSAR, and show several case studies that use LiCSAR and LiCSBAS products to measure tectonic and volcanic deformation.





Best wishes,
