On 13 November at 3.00 pm UTC, CopernicusLAC Chile will host the webinar “InSAR and the hydrosphere: anthropogenic subsidence and glaciology”, an open event inviting RedCLARA members and the scientific community in Latin America and the Caribbean to watch the live stream via the CopernicusLAC Chile YouTube channel. The talk will be presented by Francisco Delgado, a lecturer in the Department of Geology at the University of Chile.
(By: Scarlette Araya Olave, Copernicus LAC Chile) The talk will address two issues associated with the dynamics of the Earth’s hydrosphere. Firstly, it will examine the areas and rates of subsidence in Chile resulting from groundwater extraction, using the Atacama Salt Flat and Central Chile (the Valparaíso, Metropolitan and O’Higgins regions) as case studies, with reference to time series from the Sentinel-1A/B, SAOCOM-1A/B and PAZ missions.
Secondly, he will address how the Patagonian Ice Fields are moving in response to climate change, using a unique set of interferograms from the one-day tandem phases of ERS-1/2 in 1996 and Sentinel-1C/D in 2026, separated by 30 years. Furthermore, it will highlight the potential and limitations of SAOCOM-1A/B and NISAR for glaciology.
RedCLARA members and the scientific community in Latin America and the Caribbean are invited to tune in and follow this livestream on the CopernicusLAC Chile YouTube channel at: https://go.cmm.uchile.cl/seminario13nov.
