Satellite Needs Working Group (SNWG)

A coordinated approach to identify and communicate Federal Earth observation satellite needs.


About the SNWG

Through the White House National Science and Technology Council’s U.S. Group on Earth Observations (USGEO), the SNWG partners with Federal agencies to identify high-priority sustained and unmet needs for satellite Earth observations. The SNWG conducts a biennial survey to formally document and communicate satellite Earth-observing needs to NASA and other space-based Earth observation providers.

Satellite Needs Survey

The Satellite Needs Survey obtains information about key Federal agency objectives that require the application of satellite Earth observations, as well as specific measurement requirements. The survey is conducted to identify potential data gaps in the current NASA program of record and existing data resources that meet agency needs.

Previous surveys have resulted in new data products and investments to support agency missions, such as:


The following activities were selected from the 2020 SNWG assessment, and formulation activities are anticipated to begin in FY23:

  • Global Harmonized Landsat Sentinel-2 derived vegetation indices suite
  • Air quality forecasts and distributed Pandora sensors
  • Merged GNSS-RO/atmospheric sounder measurements for planetary boundary layer products
  • Sea ice from sea surface salinity
  • TEMPO/GOES Near Real-Time and Enhanced Products (TBD, in discussion with NOAA)

Process and Timeline

The Satellite Needs Survey will open on June 1, 2022 and close on July 22, 2022. Internal agency deadlines for submission will vary, with some agencies initiating internal review before July 22, 2022. Survey respondents are encouraged to communicate with their agency’s SNWG representative regarding agency-specific timelines.

The SNWG will compile submitted user agency inputs and provide an informational copy to the White House Office of Science and Technology Policy (OSTP) and Office of Management and Budget (OMB) prior to formal submission to USGEO. USGEO will then acknowledge the user agency inputs and formally submit its compilation inputs to NASA, which will analyze the user agency inputs in reference to current and future satellite plans and capabilities.
