ARIA Sentinel-1 GUNW Interferograms

The ARIA Sentinel-1 Geocoded Unwrapped Interferogram (S1 GUNW) products are Level-2 products generated by the Jet Propulsion Lab (JPL) ARIA project. The creation, discovery, and distribution of these products support the use of InSAR science around tectonically active regions, volcanoes, or areas of subsidence/uplift. These products are part of the Alaska Satellite Facility (ASF) long-term archive. The generation of the ARIA-S1-GUNW products was in part funded through collaborations with the AWS Open Data Program and NASA ROSES.The Advanced Rapid Imaging and Analysis (ARIA) Project is a collaboration between JPL and the California Institute of Technology to exploit radar and optical remote sensing, GPS, and seismic observations for hazard science and response.ARIA investigates the processes and impacts of earthquakes, volcanoes, landslides, fires, subsurface fluid movement, and other natural hazards by combining modern geodesy with ground-based observations to help improve our resilience to such events. The project develops state-of-the-art ground deformation measurement change detection methods and physical models using GPS and synthetic aperture radar observations, automating the required large-scale processing and producing essential data products for the science community.As populations grow, response to natural disasters becomes an increasingly important link between science and society. We are developing tools to use the growing networks of ground-based GPS sensors and constellations of imaging satellites for hazard monitoring and response. With these new tools, we anticipate the improvement of situational awareness immediately following disasters.ARIA S1 GUNW Interferogram ProductsThe ARIA S1 GUNW interferograms are available as NetCDF-4 products. Detailed information is available in the product specifications document. The following layers are also available as standalone GeoTIFF products:Unwrapped phaseCoherenceAmplitudeConnected components ProcessorProducts were generated by the JPL ARIA project. Initial product formation and development was done under the Getting Ready for NISAR project using the Hybrid Science Data System (HySDS). Under ACCESS funding, the product was further refined with cloud orchestration using the ASF Hybrid Pluggable Processing Pipeline (HyP3) system. The processor uses the InSAR Scientific Computing Environment (ISCE) software package developed at JPL.

ARIA Sentinel-1 地理编码解包干涉图（S1 GUNW）产品为二级产品，由喷气推进实验室（JPL）的ARIA项目生成。该产品的创建、发现和分发支持在构造活动区域、火山或沉降/隆升地区进行干涉合成孔径雷达（InSAR）科学应用。这些产品构成了阿拉斯加卫星设施（ASF）长期档案的一部分。ARIA-S1-GUNW产品的生成部分资金来源于与AWS开放数据计划及NASA ROSES的合作。高级快速成像与分析（ARIA）项目是喷气推进实验室与加州理工学院合作，利用雷达和光学遥感、全球定位系统（GPS）和地震观测，以促进灾害科学和响应的项目。ARIA通过结合现代大地测量学与地面观测，研究地震、火山、滑坡、火灾、地下流体运动等自然灾害的过程与影响，旨在增强我们对这些事件的抗灾能力。该项目开发基于GPS和合成孔径雷达观测的最新地表形变测量变化检测方法和物理模型，自动化大规模处理，并为科学界生产关键数据产品。随着人口的增长，对自然灾害的响应成为科学与社会之间日益重要的联系。我们正在开发工具，利用日益增长的地面GPS传感器网络和成像卫星星座进行灾害监测和响应。借助这些新工具，我们期待在灾害发生后立即提高态势感知能力。ARIA S1 GUNW 干涉图产品ARIA S1 GUNW 干涉图作为NetCDF-4产品提供。产品规范文档中提供了详细信息。以下图层也作为独立的GeoTIFF产品提供：展开相位、相干度、振幅、连通组件。产品由JPL的ARIA项目生成。最初的产品形成和发展是在“为NISAR做准备”项目下，使用混合科学数据系统（HySDS）完成的。在ACCESS基金的支持下，产品通过使用ASF混合可插拔处理管道（HyP3）系统进行云编排而进一步优化。处理器使用喷气推进实验室开发的干涉合成孔径雷达科学计算环境（ISCE）软件包。
