Resolution 11 of the 23rd CGPM (2007)
Version française
On the importance of SI traceable measurements to monitor climate change

    The 23rd General Conference,

    recalling Resolution 4 of the 21st General Conference on Weights and Measures (1999) concerning the need to use SI units in studies of earth resources, the environment, human well-being and related issues,

    considering

  • the expansion in the number of international and national initiatives to address the challenges and implications of climate change for the world,
  • working arrangements between the CIPM and the World Meteorological Organization (WMO),
  • the increasing importance of optical radiation measurements and physico-chemical measurements of air, ground-based as well as air-borne, and physico-chemical measurements of ocean water, which support research into the understanding of the causes and impacts of climate change,
  • the importance of basing long-term measurements which relate to climate change on the stable references of the International System of Units (SI),
  • welcomes the proposed BIPM/WMO international conference to address the increasing important role of metrology in studies on global climate change,

    recommends relevant bodies to take steps to ensure that all measurements used to make observations which may be used for climate studies are made fully traceable to SI units,

    and further recommends appropriate funding bodies to support the development of techniques which can make possible a set of SI-traceable radiometric standards and instruments to allow such traceability to be established in terrestrial and space based measurements.
