Footnote 2: email: {[EMAIL_ADDRESS], jonathan.weiss@uni-potsdam. large-scale tectonic deformation was also challenging (e.g., [9; 10]) due, in part, to typical swath widths of up to ~100 km for image mode data, such as those provided by ASAR on ENVISAT. The dual-satellite Sentinel-1 constellation, operated by the European Space Agency (ESA) as part of the European Commission's Copernicus Programme [11], has drastically changed the situation and outlook for the systematic exploitation of SAR data. Sentinel-1 routinely and frequently (every 6 or 12 days, depending on the area) acquires data over all the onshore areas on Earth, with ascending and descending information acquired in the tectonically straining regions [12]. The swath width of the Interferometric Wide Swath (IWS) mode is ~250 km, which is suitable for large-scale tectonic deformation monitoring. The data are freely and openly distributed under the ESA Copernicus Initiative for Earth Observation. Although data availability has been greatly improved by Sentinel-1, there are still hurdles to overcome for the full exploitation of this near-global coverage and the huge amount of associated data. If users start with the Single Look Complex (SLC) images (generated by ESA from the L0 raw data), they need tremendous amounts of disk space, computing resources, processing time, and extensive knowledge of InSAR techniques. Whilst several free software packages have been developed and are available for InSAR processing (e.g., GMTSAR [13; 14], ISCE [15; 16], SNAP [17]) and time series analysis (GIAnT [18; 19], MintPy [20; 21], and StaMPS [3; 22]), they remain technically complex and can be challenging to use for nonexperts. Some online services promote and facilitate the wider exploitation of Sentinel-1 InSAR products. For example, ESA's Geohazard Exploitation Platform (GEP) is a user-friendly web-based platform where users can run unsupervised InSAR time series analysis on ESA's Grid Processing On Demand (G-POD) environment [23; 24]. Users do not need to have the hardware nor software to process the huge amount of Sentinel-1 data. Instead, to obtain a result from the time series analysis, they need only to set the area of interest, select the SAR images to be processed, and choose the processing parameters before submitting the jobs online. However, adjusting processing parameters and error handling is difficult, because GEP acts as a \"black box\". Furthermore, it is currently a beta prototype, and access to it is restricted to early adopters only.
