Metrology for Climate Action Workshop 2022

Hosted by the BIPM and WMO

26-30 September 2022



The workshop is open to experts and stakeholders active in the fields of climate science, observations, modelling, GHG mitigation and measurement and measurement science willing to contribute to the development of recommendations on key technical challenge areas for metrology in these fields.

Interest in participation can be registered below, including topics that the participant wishes to contribute to, as well as suggestions of additional topics and themes for which recommendations on metrology needs should be developed. Meeting registration as well as an open call for papers and posters will be made at the beginning of 2022.

Workshop Aims

The aims of this workshop are to present progress and identify requirements for further development of advanced measurements, standards, reference data, comparisons, calibrations and metrological techniques to support the physical science basis for and adaptation to climate change, as well as mitigation efforts of greenhouse gas emissions.

The output of the workshop will be a set of recommendations on key technical challenge areas for metrology over the next decade.

This workshop follows on from two previous events:


Workshop Themes and Topics

The workshop will be organized along two major themes, covering multiple topics within each. The current list of provisional topics to be covered in each theme is given below.

Theme 1: Metrology in support of the physical science basis of climate change and climate observations

The topics (provisional) covered within the theme are Metrology in support of:

  • Atmosphere chemistry and physics
  • Ocean chemistry and physics
  • Radiation and Earth Energy Balance
  • Biosphere monitoring
  • Cryosphere Monitoring
  • Data assimilation and modelling

Other topics under consideration:

  • Reference networks and fiducial reference measurements
  • Extreme climate monitoring
  • Traceability of observations in developing economies
  • Historical climate and paleoclimatology

Theme 2: Metrology in support of greenhouse gas mitigation efforts

The topics (provisional) covered within the theme are Metrology in support of:

  • GHG Measurement Scales: establishment, maintenance, and value transfer
  • Improving national emission inventories
    • Application of atmospheric concentration measurements for emission estimates
    • Measurements for Land Use, Land Use Change, and Forestry (LULUCF)
  • Targeting and tracking emissions at local scales: cities, states and provinces
  • Quantifying carbon credits and other climate finance need for standards
  • Meeting new sensor requirements: surface-based, airborne and space-borne


Workshop Format

The workshop will be held online and incorporate an introductory plenary session, an open call and sessions for papers and posters and meetings of topic specific working groups to develop recommendations.

  • 26 September 2022: Introductory Plenary Session
  • 27-28 September 2022: Virtual Paper and Poster Presentations
  • 29-30 September 2022: Topic Specific Recommendation Development Sessions
