One million GUNW products from ARIA and counting: Enabling open-science and disaster management for everyone

NASA has committed to an open-source science initiative that enables Earth observation data transparency, inclusivity and accessibility, and reproducibility - all fundamental to the pace and quality of scientific progress. We have embraced this vision: producing standard science products freely available to the public and developing open-source, well documented state-of-the-art software in ground deformation research freely available on github and relevant across the solid earth, hydrology, and sea-level disciplines. Under the NASA ACCESS effort, we have generated over 1 million Advanced Rapid and Imaging Analysis (ARIA) Sentinel-1 Geocoded Unwrapped Phase (S1-GUNW) analysis ready datasets. The scientific analysis of these products is streamlined via the open-source ARIA-Tools, which simplifies the download and preparation of S1-GUNWs for time-series analysis - we train users to work with this software at annual scientific workshops. The S1-GUNW archive is now one of the largest and most comprehensive open InSAR datasets, spanning continental scales across most major active tectonic and volcanic regions. We have also ported the product generation tools to the open-source Hybrid Pluggable Processing Pipeline (HyP3) cloud architecture to allow our team to generate S1-GUNWs through a cloud-hosted API. These cloud tools enable other science teams to re-deploy the same architectures and containerized processing software for their own study areas. Our cloud processing unit leverages the open-source ISCE2 and delivers S1-GUNW products to the open access ASF DAAC, the latter which ensures that S1-GUNWs are available to the public for reproducible scientific analyses and disaster monitoring. Our team has also developed open-source tools to efficiently query the ASF DAAC for S1-GUNW products and utilize publicly available DEMs for InSAR processing. The current throughput of our processing system has been scaled up to 12,000 products per day. We have used the products to respond to recent volcanic unrest and earthquake events globally, and also analyze tectonic motion across entire fault systems. We are currently working to expand the ARIA S1-GUNW archive across even more study areas and expose ISCE2 processing parameters for more focused surface deformation analysis crucial for disaster response efforts.
