Introducing the OPERA Project for Systematic Surface Water, Surface Deformation, and Surface Disturbance Data Products from Satellite Observations
Abstract
Every two years the Satellite Needs Working Group (SNWG, an initiative of the U.S. Group on Earth Observations, USGEO), mandated by the White Houses Office of Management and Budget) performs a survey among the US federal agencies to identify the most needed remote sensing observations to support their highest-priority activities. NASA supports the SNWG by developing remote sensing products that address data gaps identified by the SNWG. In response to the requirements identified by the SNWG 2018 cycle, the JPL OPERA (Observational Products for End-Users from Remote Sensing Analysis) project has been funded to develop and implement three products: (1) a near-Global Dynamic Surface Water Extent Product from optical and Synthetic Aperture Radar (SAR) data, (2) a near-Global Land Surface Change Product from optical data, and (3) a North America Land Surface Deformation Product from SAR data. The source of the optical data is the harmonized Landsat-8 and Sentinel-2A/B (HLS) satellite products. The source of the radar data comprises Sentinel-1 A/B, NISAR, and SWOT data products. In addition to the three output products identified by SNWG, two intermediate products will also be produced: (1) a North America Land coregistered Single Look Complex (CSLC) stack product for all interferometric radar data, and (2) a near-Global land surface Radiometric Terrain Corrected (RTC) product derived from the SAR data. OPERAs current scope of work provides operational funding until the end of FY 2025, with the various products delivered to and distributed by three NASA Distributed Active Archive Centers (DAACs). The presentation will discuss the OPERA products, the processing and analysis, the Stakeholder Engagement Program, and the timeline.
