To provide a consistent and coordinated response from the NMI radiometry community to the needs of the satellite-observation communities, particularly those related to climate change, this task group has the following objectives:

  • Review the relevant documented requirements from the community relating to satellite observations, including:
    • The BIPM-WMO Metrology for Climate Action (2022) report (aka “Report”), recommendations 1A.1, 1B.2, 1B.8 – 1B.11, 1C.1 – 1C.7, 1D.1, 1D.4, 1D.6, 1D.9, 1E.1, 2D.1
    • The CEOS-GSICS SI-Traceable Space-Based Climate Observation System (2019) report (doi: 10.47120/npl.9319)
    • The 2005 report “Satellite instrument calibration for measuring global climate change: Report of a workshop”, published in BAMS. (doi: 10.1175/BAMS-86-9-1303)
  • Document the current capabilities of NMIs and research institutes and their potential for near-term observation improvement capabilities
  • Produce a roadmap for the development/implementation of radiometric capability to provide calibration services for optical (UV, visible, SWIR, thermal IR) satellite sensors (pre- and post- launch)
    • Establish whether more specific reference standards and/or comparisons are needed to support the confidence in delivered SI-traceability to satellite sensor calibrations,
    • Support NMI and DMI members of CCPR to assess needs and opportunities in satellite radiometric observations by discussing documented requirements and sharing information from relevant committees. Provide materials for coherent joint messages to be given for various conferences and where appropriate encourage collaborative projects to support the aims of the members.
    • Encourage space agencies to establish and report quantitative requirements and needs for current and future missions in a manner accessible to the Metrology community.
  • Recommend specific areas where funding from NMIs or other funding agencies could enable meeting the Report and roadmap objectives. Consider what is best done collaboratively, independently or by a single NMI, and review options for funding in national and international programmes.
  • Coordinate with relevant CCs (e.g., CCEM, CCT, CCQM, CCTF) on non-radiometric satellite sensor requirements.
