2 CERN.ZENODO 10.5281/zenodo.54704 Bignami, Christian Christian Bignami Istituto Nazionale di Geofisica e Vulcanologia Zenodo 2016 Puyehue DinSAR ENVISAT Eruptions 2016-06-03 https://zenodo.org/record/54704 Creative Commons Zero - CC0 1.0 Open Access <p>On June 4, 2011, Puyehue-Cordon Caulle complex began its eruptive activity. This intense eruption lasted for several months and was characterized by both effusive and explosive activities. ENVISAT ASAR sensor imaged the eruption of the volcano, and the sin-eruptive surface deformation was estimated by using Differential SAR Interferometry (DinSAR). The present dataset is the result of such estimation, and reports the SAR Line of Sight (LoS) displacement, in metres, related to the first phase of the eruption. In particular, the ASAR images used for DinSAR processing are dated May 08, 2011 and June 07, 2011. The &nbsp;interferogram shows a large deflating area in the Cordon Caulle section of the volcanic complex that reaches a value of -90 cm. Moreover, few centimetres of deflation are also present in the west flank of Puyehue stratocone.</p> Input data: ENVISAT-ASAR images on May 08, 2011 and June 07, 2011, ascending orbit Topographic phase removed with SRTM DEM Spatial Baseline: 98 m Multi-look factor: 2 range x 6 azimuth LoS: 40.8° off-nadir Projection: GEO Lat-Long WGS84
