Stakeholder Engagement Program (SEP)

NASA's Satellite Needs Working Group (SNWG) includes a Stakeholder Engagement Program (SEP) focused on supporting SNWG product user communities with relevant training and end-user engagement activities. SEP efforts include aggregation and delivery of relevant training in remote sensing topics, background on developed products, and training on how to efficiently access and utilize new products for stakeholder decision-making. Resources aggregated or provided by SEP focus on NASA and partner contributions in areas of remote sensing training, code recipes, and data processing.

The biennial SNWG survey and assessment cycles have led to the funding of new solutions which undergo processes for their formulation, implementation, and operational deployment. Solutions developed and deployed for operational use through new web portals, data products, and other capabilities are referenced below with links that direct users to more information.

Harmonized Landsat Sentinel-2 (HLS)

Harmonized Landsat Sentinel-2 (HLS)

HLS provides consistent surface reflectance (SR) data from the Operational Land Imager (OLI) aboard the joint NASA/USGS Landsat 8 satellite and the Multi-Spectral Instrument (MSI) aboard the European Space Agency’s (ESA) Copernicus Sentinel-2A and Sentinel-2B satellites. The combined measurement enables global observations of land every 2–3 days at 30 m spatial resolution. Our SEP effort provides resources on the use of HLS in collaboration with NASA’s LP DAAC, Applied Science: Capacity Building program, and other partners.

Ice, Cloud & Land Elevation Satellite-2 (ICESat-2) Quick Look Products

Ice, Cloud & Land Elevation Satellite-2 (ICESat-2) Quick Look Products

Users of ICESat-2 data for various atmospheric, land, and ice analysis submitted needs for products to be generated with reduced latency. As a result, an SNWG solution focused on the generation of ICESat-2 “Quick Look” products, that can be delivered at reduced latency relative to the standard ICESat-2 products permanently archived by NSIDC DAAC. Quick Look versions of products focus on latency of 3-5 days versus the typical 45-day latency of standard products.

Products to be developed as Quick Look versions include atmospheric profiles, along-track sea ice, vegetation and canopy height, and inland water bodies. In addition, the ICESat-2 team will explore development of a new Lake Ice Freeboard product with standard and quick-look latency. ICESat-2 Quick Look products will be released to the community as they are developed, with training and engagement supported by the SNWG Stakeholder Engagement Program.

Observation Products for End-Users for Remote Sensing Analysis (OPERA)

Observation Products for End-Users for Remote Sensing Analysis (OPERA)

Started in April 2021, the Observation Products for End-Users for Remote Sensing Analysis (OPERA) project at the Jet Propulsion Laboratory collects data from satellite radar and optical instruments to generate three products that respond to the needs identified by various federal agencies during the 2018 cycle (a.k.a. Cycle 2) of the Satellite Needs Working Group development activities, namely:

  • a near-global Surface Water Extent product suite, 
  • a near-global Surface Disturbance product suite, and 
  • a North-America Displacement product suite.

The first is generated from synthetic aperture radar (SAR) and optical data. The second is generated from optical data only. The third is generated from Interferometric SAR data. In addition, OPERA is producing two intermediate SAR data products:

  • a North America land coregistered single-look complex (CSLC) product suite; and
  • a near-global land-surface radiometric terrain-corrected (RTC) product.

The OPERA data products and time series are derived from measurements made by the instruments aboard the Sentinel-1A/1B, Sentinel-2A/2B, and Landsat-8 satellites, to be augmented by the measurements from the radars on the soon-to-be-launched NISAR and SWOT satellites. All products will be distributed though NASA's Distributed Active Archive Centers (DAACs). 

As part of its SNWG activities the OPERA team engages in coordination with the overall SNWG SEP managed by the SNWG program office at IMPACT. This includes end-user engagement and training with federal agencies, interested satellite data users, and members of the broader science and applications communities.

For more information on the project and its activities visit the OPERA website.
