Abstract Synthetic Aperture Radar (SAR) Differential Interferometry (DInSAR) and its extensions to manage time series are nowadays well-known and mastered techniques to perform among others land-motion monitoring. We present here a fully automated monitoring service based on DInSAR and Multidimensional Small Baseline Subset (MSBAS) methods. The automated processing chain named “InSAR automated Mass processing Toolbox for multidimensional Time series” (MasTer) is demonstrated with the peculiar case of the Laguna del Maule and Domuyo volcanoes, which are known to undergo significant inflation up to several cm or tens of cm per year. The here-described monitoring service is made of three components: an InSAR command line processor, the MSBAS processor and a number of shell scripts automatizing all tasks, from data downloading to updated displacement maps and time series. Thanks to the European Commission Copernicus Service, data are freely available every 12 or 6 days along each orbit, depending on ESA acquisition plan. Linear deformation rate maps and time series of vertical and East-West ground deformation computed by the MasTer tool are updated every 1–6 days on a web page, according to the S1 data availability. Interested user can request additional time series at coherent pixels that wouldn't be displayed on the web page and receive them by e-mail within a minute. Processing chain and preliminary observations at Domuyo and Laguna del Maule test site are presented and commented. The nearly 6 years long 2D time series of ground deformation allow highlighting recent changes in the well-known deformation at both volcanoes: Domuyo inflation stabilizes since beginning of 2019 while deformation at Laguna del Maule seems to gently accelerate since mid 2018. New deformation features are also identified, such as a 2 km wide 3 cm/yr circular subsidence at Laguna del Maule as well as a 2 cm/yr downward and 1 cm/yr eastward movement located to the East of Laguna Fea.

使用 Sentinel-1 MSBAS 时间序列对 Domuyo - Laguna del Maule 地区（阿根廷）进行持续自动地面变形监测：2015-2020 年期间的方法描述和首次观测

摘要 合成孔径雷达 (SAR) 微分干涉测量 (DInSAR) 及其对时间序列管理的扩展是当今众所周知且掌握的技术，用于执行陆地运动监测等。我们在此展示了一种基于 DInSAR 和多维小基线子集 (MSBAS) 方法的全自动监控服务。名为“用于多维时间序列的 InSAR 自动化质量处理工具箱”(MasTer) 的自动化处理链通过 Laguna del Maule 和 Domuyo 火山的特殊案例进行了演示，已知这些火山经历了高达几厘米或几十厘米/每厘米的显着膨胀。年。这里描述的监控服务由三个组件组成：一个 InSAR 命令行处理器、MSBAS 处理器和一些自动化所有任务的 shell 脚本，从数据下载到更新的置换贴图和时间序列。多亏了欧盟委员会哥白尼服务，每个轨道上每 12 或 6 天免费提供一次数据，具体取决于欧空局的采购计划。根据 S1 数据的可用性，由 MasTer 工具计算的线性变形率图和垂直和东西向地面变形的时间序列每 1-6 天在网页上更新一次。感兴趣的用户可以在网页上不会显示的连贯像素上请求额外的时间序列，并在一分钟内通过电子邮件接收它们。介绍并评论了 Domuyo 和 Laguna del Maule 试验场的加工链和初步观察结果。近 6 年的地面变形二维时间序列突出显示了两座火山著名变形的近期变化：
