Sentinel-1 Interferograms and time series collection on Afar 2014-2021
This project aims to characterize the spatial and temporal distribution of the deformation in the region of the Afar depression. The aim is to better understand large-scale tectonics (localization of divergent borders, kinematics of the triple point), but also the dynamics of volcanic, seismic and aseismic events, and the mechanics of active faults. The issue of gravity hazard will also be addressed.
Three types of products are made available for each orbit portion processed (see <a href=" https://formater.pages.in2p3.fr/flatsim/" target="_blank"> detailed description </a> )
- "INTERFEROGRAM": this brings together the differential interferograms, wound and unwound, in radar or terrain geometry, filtered or not, at different resolutions, as well as the atmospheric correction maps used and spatial coherence for each interferogram.
- "TIMESERIES": this includes maps of movement in time series and average speed, according to the satellite line of sight (LOS), and quality indices of time series processing.
- "AUXILIARYDATA": this directory contains maps indicating the LOS vector, the DTM in radar geometry, at different resolutions, the radar-field geometry transcoding tables, and temporal coherence, as well as a set of figures and parameter files specific to the processing of the time series.

- Statement
-
These collections of interferograms and displacement time series are produced by CNES as part of the FLATSIM service. This service is developed in collaboration with the ForM @ Ter Data and Services pole and the ISTerre, LGL-TPE and IPGP laboratories. The radar images used come from the TOPSAR Sentinel-1 archive (Copernicus data). The calculations are made from the NSBAS interferometric processing chain
