The ARIA-S1-GUNW: The ARIA Sentinel-1 Geocoded Unwrapped Phase Product for Open InSAR science and Disaster Response - Proceedings

NASA has committed to open-source science that enables Earth observation data transparency, inclusivity and accessi- bility, and reproducibility – all fundamental to the pace and quality of scientific progress. We have embraced this vision: to produce standard InSAR science products generated from state-of-the-art methods that are freely available to the public through NASA Data Active Archive Centers (DAACs). The Advanced Rapid Image Analysis (ARIA) project’s Sentinel-1 Geocoded Unwrapped Phase Product (ARIA-S1-GUNW) is a 90 meter InSAR product spans major, land-based fault sys- tems, the US Coast, and active volcanic regions through the complete Sentinel-1 record. The products enable the mea- surement of centimeter-scale surface displacement with ap- plications across the solid earth, hydrology, and sea-level dis- ciplines. The ARIA-S1-GUNW also enables rapid response after earthquakes, landslides, and subsidence. The ARIA- S1-GUNW products are freely available through the Alaska Satellite Facility (ASF) DAAC. In the last year, we have suc- cessfully grown the archive to over 1.1 million products (a 6 fold increase in this period), through NASA ACCESS by improving our processing workflow and leveraging the cloud architecture HyP3. We are continuing to partner with re- searchers to generate more products over relevant areas of scientific interest. All the processing software and cloud in- frastructure are open-source to ensure reproducibility and en- able other scientists to modify, improve upon, and scale their own cloud workflows for related InSAR analyses. We have, in parallel, developed and supported open-source and well- documented tools to further streamline time-series analysis from the ARIA-S1-GUNW into deformation analysis work- flows.

美国国家航空航天局（National Aeronautics and Space Administration, NASA）始终致力于推进开源科学事业，以实现地球观测数据的透明性、包容性、可及性与可重复性——这些要素皆是科学研究进展速度与质量的核心根基。我们秉持这一愿景，旨在产出采用前沿方法生成的标准化干涉合成孔径雷达（Interferometric Synthetic Aperture Radar, InSAR）科学产品，并通过NASA数据主动存档中心（Data Active Archive Centers, DAACs）向公众免费开放。
高级快速图像分析（Advanced Rapid Image Analysis, ARIA）项目的Sentinel-1地理编码解缠相位产品（ARIA-S1-GUNW）是一款分辨率为90米的InSAR产品，覆盖全球主要陆地断层系统、美国海岸以及活跃火山区域，数据集涵盖完整的Sentinel-1观测记录。该产品可实现厘米级地表位移测量，应用覆盖固体地球、水文与海平面相关研究领域。ARIA-S1-GUNW还可在地震、滑坡与地面沉降事件发生后提供快速响应支持。
ARIA-S1-GUNW产品可通过阿拉斯加卫星设施（Alaska Satellite Facility, ASF）DAAC免费获取。过去一年间，依托NASA ACCESS项目，我们通过优化处理流程并利用云架构HyP3，成功将存档产品总量提升至110万件以上，同期增幅达6倍。我们仍在持续与科研人员合作，在具备科学研究价值的相关区域生成更多产品。所有处理软件与云基础设施均已开源，以保障研究可重复性，并允许其他科研人员修改、改进并拓展其自身用于相关InSAR分析的云工作流。
与此同时，我们还开发并维护了开源且文档完备的工具，以进一步简化从ARIA-S1-GUNW数据到形变分析工作流的时间序列分析流程。
