Interferograms and time series collection on Central Chile 2014-2022

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.

Purpose

The project aims to quantify the deformations associated with the Andean subduction in central Chile, with the main objectives to

(1) constrain the kinematics and interseismic coupling of the subduction interface and crustal faults, at the front and inside the Andes mountain range,

(2) analyze co- and post-seismic deformations during different seismic crises and slow slip episodes,

(3) understand the link between the seismic cycle and relief building,

(4) monitor the behavior of volcanoes in the Andean arc. Another objective is to characterize erosion episodes during extreme climatic events in the Atacama Desert.

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
