Title: | Thirty years of volcano geodesy from space at Campi Flegrei caldera (Italy) | Journal: | Scientific Data | Series/Report no.: | /9 (2022) | Publisher: | Springer-Nature | Issue Date: | 26-Nov-2022 | DOI: | 10.1038/s41597-022-01849-7 | Keywords: | InSAR, cGNSS, Levelling | Subject Classification: | 04.03. Geodesy | Abstract: | This work provides the mean ground deformation rates and ground displacement time series of the Campi Flegrei caldera (Italy) retrieved by satellite remote sensing data analysis from 1992 to 2021. Synthetic Aperture Radar (SAR) images acquired by ERS 1-2 (1992-2002), Envisat (2003-2011) and Cosmo-SkyMed (2011-2021) are processed by multi-temporal SAR Interferometry (InSAR) approach using the same technique, parameters and reference system, to obtain for the first time a homogeneous and time-continuous dataset. The validation of the InSAR products is carried out by comparison with the measurements provided by precise levelling lines and cGNSS stations. The produced outcomes offer an overview on the temporal behaviour of ground deformation at Campi Flegrei along an unprecedented time window of about 30 years and can be exploited by the scientific community for supporting and improving the knowledge of the dynamics of the caldera. |
