NPOESS User Working Group

The proposal aims to establish a User Working Group to provide user-perspective insights on NPOESS system capabilities, products, and improvements. It seeks to address gaps, product evolution, algorithm enhancements, and system assessment, involving external advisory teams and ensuring alignment with NOAA initiatives.

  1. NPOESS User Working Group A Proposal to the NOAA Science Advisory Board Gregory W. Withee Assistant Administrator for Satellite and Information Services November 3, 2003

  2. Background • The IPO and NESDIS together share responsibility for the overall NPOESS system • A number of groups provide guidance, advice and/or oversight concerning various aspects of the overall NPOESS system • There is no group looking at the overall NPOESS system from the perspective of NOAA end users

  3. Command, Control & Communications NOAA IPO Data Utilization • L3/4 Product Generation • Blended Products • Reformatted Products Environ. Modeling Systems Interface Data Processing Segment Product Processing • System Integration • Operational Test & Eval. • Data Assimilation NPOESS Functional Architecture NPOESS Satellite Data Collection Science Support NOAA Central XDRs (HDF5) User Community Long Term Archive (CLASS)

  4. Groups providing guidance, advice and/or oversight for NPOESS • NPOESS Science Team, an internal group reporting to Northrop Grumman • NPOESS Science Advisory Team, an external group chaired by Joe Friday reporting to Northrop Grumman • Integrated Weather Product Test Bed Team, overseeing Raytheon’s IDPS and reporting to Northrop Grumman • A number of Instrument Cal/Val Teams reporting to Northrop Grumman and the IPO • Eight Operational Algorithm Teams (OAT) and a Central Users’ Forum reporting to the IPO • Data Archive Board reporting to NESDIS OSDPD • Climate Monitoring Working Group, chaired by Mark Abbott and reporting to NOAA SAB • Climate and Global Change Working Group, chaired by Otis Brown and reporting to NOAA SAB • A new 1-year NAS/BASC study looking at Climate Data Records

  5. Wide Range of NOAA Users • Operational – operational observations to support weather forecasting – where there is feedback within hours to days on the impact of observations on forecasts • Research – sustained systematic observations to support climate change – where similar feedback may not come for years to a decade or more

  6. Proposed Terms of Reference • As a sanctioned Working Group of the NOAA SAB, provide scientific advise and broad program direction on the on the condition and capabilities of the NPOESS system from the user perspective • The NPOESS system is meant to include the space segment, NOAA Central (from Interface Data Processing Segment thru product generation to utilization), CLASS archive, and supporting science • Complement, and coordinate with, the existing Climate Monitoring and Climate & Global Change Working Groups

  7. What are some initial issues? • Identification of gaps: How will needs be met in the NPOESS era for: • QuikSCAT-class surface vector winds? • Jason-class sea surface topography? • Preplanned product improvement EDRs (eg, carbon gases)? • Assessment of planned system: • Will CLASS have sufficient capacity in time for NPOESS? • How well will resulting products contribute to the long-term climate record • Product improvement: What is the plan for evolving the algorithms in response to applications such as fine-spatial-resolution ocean products approaching the coast?

  8. What are some initial issues?(continued) • Regarding product improvement: During the NPOESS era, to what extent will/might there be: • Access to lower-level data? • Open and transparent algorithms? • Competitively selected, peer-reviewed science teams?

  9. Next Steps • NOAA SAB: • approve written Terms of Reference • address membership & designation of chair • First meeting in early CY04 • NPOESS User Working Group starts by reviewing the components of the overall NPOESS system
