Sentinel-1 Interferograms and time series collection on eastern border of tibetan plateau 2014-2021

The objective of the project is to quantify and model the current deformations on the eastern edge of the Tibetan plateau. It focuses on deformations of tectonic origin, at the scale of active faults as well as at the continental scale, to address issues of the seismic cycle and uplift mechanisms of the Tibetan plateau. This project is also interested in non-tectonic signals present in time series (hydrological overloads in particular).


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
